Description

  The present invention relates to a rope pinching device and an anti-winding device.

  The utility pole P erected in the mountain field causes vines and other vines to be wound around the branch line, causing a short circuit accident or hindering overhead work. In order to prevent this, as shown in FIG. 23, a cylindrical wrinkle prevention device G composed of two half-broken bodies G1 and G2 is loosely fitted to the rope W forming the branch line. The anti-winding device G shown in FIG. 23 (a) includes a rope pinching device for pinching the rope W inside so as not to slip down vertically along the rope W. As shown in FIG. 23 (b), there is a type in which a rope pinching device H that is separate from the anti-winding device G is provided vertically below the anti-winding device G.

  As a rope pinching device, for example, there is a device having two locking claws as described in Patent Document 1 and pinching the rope W by the two locking claws. The two locking claws are provided with an elastic force by a spring so that the distal ends thereof are angularly displaced in a direction approaching each other. Against this spring force, the two locking claws are manually angularly displaced in the direction in which the tip part moves away from each other, and the rope pinching device is arranged so that the rope is positioned between the two locking claws. Then, when the hands are released from the two locking claws, the two locking claws are angularly displaced in the direction in which the distal ends approach each other, and the rope W is clamped.

Japanese Patent No. 2883045

  The rope sandwiching device described in Patent Document 1 has an advantage that it is difficult to be displaced with respect to the rope W. Specifically, when the rope clamping device described in Patent Document 1 is slightly shifted vertically downward along the rope W, the two locking claws are caused to end by friction with the rope W. The parts are angularly displaced in the direction of approaching each other. As a result, the distance between the tip parts is reduced, the clamping force is increased, and further displacement is prevented. Moreover, since the rope clamping device described in Patent Document 1 is configured to clamp the rope W by angular displacement of the two locking claws, the two locking claws are opposed to each other. The rope W is locally pinched by a part of the surface. Therefore, it is difficult to disperse the pinching force, and the rope W can be firmly pinched. Furthermore, since the rope clamping device described in Patent Document 1 is configured to clamp the rope W by angular displacement of the two locking claws, the rope clamping device is displaced vertically downward. Even if it is a case, the state which the two latching claw parts pinch the rope W locally is maintained, and the firm clamping state can be maintained.

  As described above, the rope sandwiching device described in Patent Document 1 exhibits some advantageous effects. However, as described above, it is necessary to manually attach the rope sandwiching device. Usually, since the attachment work is performed with thick gloves, it is difficult to manually angularly displace the two locking claws, and it is difficult to attach the rope pinching device.

  As a rope pinching device that solves such a problem, a rope pinching device J shown in FIGS. 24 and 25 can be considered. The rope pinching device J has two L-shaped plates 31a and 31b, and clamps the rope by the flat plate portions 31aa and 31ba of the two L-shaped plates 31a and 31b which are parallel to each other. The two L-shaped plates 31a and 31b are configured to be slidable along guide hole portions 32a and 32b provided in the base portion 32, respectively. The two L-shaped plates 31a and 31b are given an elastic force by a spring (not shown) so as to approach each other along the guide hole portions 32a and 32b, and the rope W is sandwiched between the flat plate portions 31aa and 31ba. If not, the state shown in FIG.

  When the trigger portion 33 is pulled downward from the state of FIG. 25A, the two L-shaped plates 31a and 31b slide and move away from each other along the guide holes 32a and 32b. It will be in the state of (b). When the state shown in FIG. 25B is reached, a not-shown convex portion of the trigger portion 33 and a not-shown concave portion of the base portion 32 are fitted, and the state shown in FIG. 25B is maintained. The rope pinching device J is provided with such a structure in one half-cracked body and a projection (not shown) on the other half-cracked body. The protrusion provided on the other half-cracked body presses the trigger part 33 when the other half-cracked body is bonded to the other half-cracked body, and the convex part of the trigger part 33 and the concave part of the base part 32 Thus, the two L-shaped plates 31a and 31b approach each other along the guide hole portions 32a and 32b by the elastic force, and as a result, the cord located between the flat plate portions 31aa and 31ba. The strip W is sandwiched between the flat plate portions 31aa and 31ba. Therefore, according to the rope pinching device J, the rope W can be automatically pinched when the two half cracks are joined.

  In addition, the rope pinching device J has an advantage that it is difficult to be displaced with respect to the rope W, similarly to the rope pinching device described in Patent Document 1. Specifically, when the rope pinching device J is slightly shifted vertically downward along the rope W, the two L-shaped plates 31a and 31b approach each other by friction with the rope W. As a result, the distance between the flat plate portions 31aa and 31ba is reduced, the clamping force is increased, and further displacement is prevented.

  However, since the rope clamping device J is configured to clamp the rope by the two flat plate portions 31aa and 31ba, the rope cannot be clamped locally, and the clamping force is easily dispersed. The rope cannot be clamped firmly. Further, in order to make the L-shaped plates 31a and 31b slidable, it is necessary to configure the rope pinching device J to be long in the extending direction of the rope, and it is difficult to reduce the size of the rope pinching device J. The number of parts increases.

  The present invention is for solving the above-described problems, and an object of the present invention is to provide a rope pinching device and an anti-winding prevention device capable of firmly and automatically pinching a rope.

The claw receiving wall portion 15 is erected in a direction away from the opposing wall portion 8a (arrow Z1 direction). The arrow Z1 direction is the opposing wall of one half-cracked body 3a when in the fitted state. This is a direction from the portion 8a toward the opposing wall portion 8b of the other half cracked body 3b.

  The claw receiving wall portion 15 is a “claw receiving portion” in the present invention, and is a member that sandwiches a branch line with the locking claw portion 13. At least the surface of the claw receiving wall 15 that faces the locking claw 13 is covered with an elastic layer. FIG. 6 shows details of the claw receiving wall portion 15 covered with the elastic layer 15a. The claw receiving wall portion 15 shown in FIG. 6 is configured by fitting an elastic layer 15a formed of synthetic rubber or the like into a groove portion of a wall main body 15b formed of polycarbonate or the like. The thickness of the elastic layer 15a is, for example, 2 mm to 6 mm, and the Shore hardness is about 70 degrees. In addition, you may adhere | attach the elastic layer 15a on the surface of the wall part main body 15b instead of comprising like FIG. In order to reduce the number of parts, the claw receiving wall portion 15 (wall portion main body 15b) is preferably formed integrally with the base portion 14.

  The locking claw portion 13 is a columnar member that extends in the direction of the arrow Z1 and in the direction of the arrow Z2 that is the opposite direction (the arrow Z1 direction and the arrow Z2 direction are collectively referred to as the Z direction). Further, it is configured to be angularly displaceable. The locking claw portion 13 is formed with a hole 13a through which the angular displacement center axis S passes. The shape of the hole 13a is a column shape extending in the direction of the angular displacement central axis S, and the angular displacement shaft portion 16 is inserted into the hole 13a.

  The locking claw portion 13 is configured such that the distance between the side surface 13b of the locking claw portion 13 and the claw receiving wall portion 15 changes continuously by angular displacement. In FIG. 7, a mode when the latching claw part 13 carries out an angular displacement is shown. In FIG. 7, the retaining portion 18 is omitted. The locking claw portion 13 can be angularly displaced in either one direction (arrow D1 direction) and the other direction (arrow D2 direction) around the angular displacement center axis S. FIG. ), FIG. 7B, and FIG. 7C, the locking claw portion 13 is angularly displaced in the direction of the arrow D2. As shown in FIG. 7A to FIG. 7C, the engagement claw portion 13 is angularly displaced in the direction of the arrow D <b> 2, so that between the side surface 13 b of the engagement claw portion 13 and the claw receiving wall portion 15. Distance L gradually decreases. Here, the distance L is the shortest distance between the side surface 13 b of the locking claw portion 13 and the claw receiving wall portion 15. In the present embodiment, the distance L becomes 0 when the engaging claw portion 13 is further angularly displaced in the direction of the arrow D2 from the state shown in FIG. That is, the side surface 13 b of the locking claw portion 13 abuts on the claw receiving wall portion 15.

  At least the surface of the locking claw 13 that faces the claw receiving wall 15 is covered with an elastic layer. In FIG. 8, the detail of the latching claw part 13 coat | covered with the elastic layer 13c is shown. The locking claw portion 13 shown in FIG. 8 is configured by fitting an elastic layer 13c formed of synthetic rubber or the like into a groove portion of a claw body 13d formed of polycarbonate or the like. The thickness of the elastic layer 13c is, for example, 2 mm to 6 mm, and the Shore hardness is about 70 degrees. In addition, you may adhere | attach the elastic layer 13c on the surface of the nail | claw part main body 13d instead of comprising like FIG.

  The angular displacement shaft portion 16 is a substantially columnar member that stands on the base portion 14 and extends in the Z direction. More specifically, it is a member in which two protrusions 16b are formed on the side surface of the upper end, which is the end on the arrow Z1 direction side, of the column 16a extending in the Z direction. The central axis of the cylinder 16a coincides with the angular displacement central axis S. As described above, the angular displacement shaft portion 16 is inserted through the hole 13 a of the locking claw portion 13. In the present embodiment, there are two protrusions 16b. However, as a modification of the present embodiment, the number of protrusions 16b may be one, or may be three or more.

  As shown in FIG. 7A, the shape of the angular displacement shaft portion 16 when viewed in the direction of the arrow Z2 is the same as the shape when the hole 13a of the locking claw 13 is viewed in the direction of the arrow Z2. The same shape or a slightly smaller shape. Therefore, in the state shown in FIG. 7A, the position of the locking claw portion 13 through which the angular displacement shaft portion 16 is inserted in the Z direction is relatively far from the base portion 14, thereby the angular displacement shaft portion. When a part or all of the 16 protrusions 16b are in the hole 13a of the locking claw 13, the hole 13e of the locking claw 13 surrounding the hole 13a and the protrusion 16b of the angular displacement shaft part 16 Are engaged, and the locking claw portion 13 cannot be angularly displaced.

  As described above, a state in which the hole 13e and the protrusion 16b are fitted and the locking claw 13 cannot be angularly displaced is hereinafter referred to as a locked state. The distance L between the side surface 13b of the locking claw portion 13 and the claw receiving wall portion 15 in the locked state is the maximum thickness of the branch line that can be clamped by the rope clamping device 1. As shown in FIGS. 7A to 7C, the locking claw portion 13 can be angularly displaced so that the distance L becomes smaller than the distance L in the locked state.

  FIG. 9 schematically shows the locking claw portion 13 and the angular displacement shaft portion 16 in the locked state. 9A is a cross-sectional view taken along line AA in FIG. 7A, and FIG. 9B is a cross section taken along line BB in FIG. 7A. It is sectional drawing when setting it as a line. In FIG. 9, the entire protrusion 16 b is in the hole 13 a of the locking claw 13, thereby being locked.

  The angular displacement shaft portion 16 is a member that can lock the locking claw portion 13 as described above, and is an “angular displacement prevention portion” according to the present invention. The angular displacement preventing portion is in a state where the locking claw portion 13 is angularly displaced in the direction of the arrow D1 as shown in FIG. 7A, and the locking claw portion 13 is located at the position on the arrow Z1 direction side as shown in FIG. When it comes, the locking claw portion 13 is brought into the locked state.

  A state in which the locking claw portion 13 can be angularly displaced with respect to the locked state is referred to as a non-locked state. For example, even in the state shown in FIG. 7A, the position of the locking claw portion 13 through which the angular displacement shaft portion 16 is inserted in the Z direction is relatively close to the base portion 14, whereby the angular displacement shaft portion When a part of the 16 projections 16b is not in the hole 13a of the locking claw 13, the locking claw 13 can be angularly displaced as shown in FIGS. 7 (a) to 7 (b). It is.

  FIG. 10 schematically shows the locking claw portion 13 and the angular displacement shaft portion 16 in the unlocked state. 10A is a cross-sectional view taken along line C-C in FIG. 7C, and FIG. 10B is a cross-sectional view taken along line DD in FIG. 7C. It is sectional drawing when setting it as a line. In FIG. 10, the entire portion of the protruding portion 16 b is outside the hole 13 a of the locking claw portion 13, thereby being in an unlocked state.

  The retaining portion 18 is a member that prevents the angular displacement shaft portion 16 from coming off from the hole 13 a of the locking claw portion 13. For example, the retaining portion 18 is a bolt or a pin having a head portion 18a larger than the hole 13a. In the present embodiment, as shown in FIG. 4, the retaining portion 18 is a separate member that is inserted into the hole at the upper end portion of the angular displacement shaft portion 16, but as a modification of the present embodiment, the angular displacement shaft It may be integrally formed with the part 16. FIG. 11 shows a modification in which the retaining portion 18 and the angular displacement shaft portion 16 are integrally formed. In the modified example shown in FIG. 11, after inserting the integrated body of the angular displacement shaft portion 16 and the retaining portion 18 into the hole 13 a of the locking claw portion 13, the end portion of the integrated body is fixed to the base portion 14. Composed. Thus, the number of parts can be reduced by integrally forming the retaining portion 18 and the angular displacement shaft portion 16. In addition, when the retaining portion 18 and the angular displacement shaft portion 16 are separate members as in the present embodiment, the number of parts can be reduced by integrally forming the angular displacement shaft portion 16 and the base portion 14. Can do.

  The elastic force imparting portion 17 is a member that imparts a first elastic force and a second elastic force to the locking claw portion 13. The first elastic force is a force toward the arrow Z1 direction. In the locked state as shown in FIG. 9, the locking claw portion 13 is pushed in the direction of the arrow Z <b> 1 by the first elastic force, and is locked by the elastic force applying portion 17 and the head portion 18 a of the retaining portion 18. The nail | claw part 13 will be in the state pinched | interposed. In the unlocked state as shown in FIG. 10, the locking claw portion 13 is pushed in the direction of the arrow Z <b> 1 by the first elastic force, and the elastic force applying portion 17 and the protruding portion 16 b of the angular displacement shaft portion 16. The locking claw portion 13 is sandwiched. When the locking claw portion 13 is angularly displaced in the direction of the arrow D1 so that the unlocked state shown in FIG. 10 is changed to the locked state shown in FIG. 9, the locking claw portion 13 is moved by the first elastic force. Move in the direction of the symbol Z1.

  The second elastic force is a force that angularly displaces the locking claw portion 13 in the direction of the arrow D2, and is a force that increases in size when the locking claw portion 13 is angularly displaced in the direction of the arrow D1. Therefore, the second elastic force is larger in the state shown in FIG. 7A than in the state shown in FIG. When the latching claw portion 13 is angularly displaced in the direction of the arrow D2 until the distance L between the side surface 13b of the latching claw portion 13 and the claw receiving wall portion 15 becomes zero, the second elastic force May be 0. Further, in the locked state shown in FIG. 9, even if the second elastic force is large, it cannot be angularly displaced. In the state shown in FIG. 7B, the locking claw portion 13 is automatically angularly displaced by the second elastic force so as to be in the state of FIG. 7C.

  In the present embodiment, the elastic force applying part 17 is a compression torsion coil spring connected to the locking claw part 13. FIG. 12 shows a compression torsion coil spring 19 which is an example of a compression torsion coil spring. The compression torsion coil spring 19 is a member formed in a substantially spiral shape, and has both characteristics of the compression coil spring and the torsion coil spring. When the compression torsion coil spring 19 is used as the elastic force imparting portion 17, the substantially spiral central axis coincides with the angular displacement central axis S, and the compression torsion coil spring 19 is mounted so as to surround the angular displacement shaft portion 16. Is done.

  The compression torsion coil spring 19 has a gap in the central axis direction, and can be compressed in the central axis direction. The compressed compression torsion coil spring 19 generates an elastic force so as to extend in the central axis direction. As described above, in the state shown in FIGS. 9 and 10, the elastic force imparting portion 17 applies the first elastic force to the locking claw portion 13. Therefore, when the compression torsion coil spring 19 is used as the elastic force applying unit 17, the compression torsion coil spring 19 is compressed in the state shown in FIGS. 9 and 10 so that the compression torsion coil spring 19 is compressed more than the natural state. It is necessary to provide between the base portion 14 and the locking claw portion 13.

  When the compression torsion coil spring 19 moves the end of the arrow Z1 direction in the direction of the arrow R1 to open the coil, it generates an elastic force in the direction of the arrow R2 that attempts to close the coil. As described above, the elastic force imparting portion 17 attempts to angularly displace the locking claw portion 13 in the arrow D2 direction when the locking claw portion 13 is angularly displaced in the arrow D1 direction. The second elastic force is applied. Therefore, when the compression torsion coil spring 19 is used as the elastic force imparting portion 17, the arrow R1 direction is the arrow D1 direction, the arrow Z1 direction end is connected to the locking claw portion 13, and the arrow It is necessary to connect the end portion in the Z2 direction to the base portion 14.

  As a modification of the present embodiment, the elastic force imparting portion 17 may be configured by a torsion coil spring and a compression coil spring. FIG. 13 shows an elastic force applying portion 17 composed of a torsion coil spring 20 and a compression coil spring 21. The torsion coil spring 20 is connected to the base portion 14 and the locking claw portion 13 so that the opening direction of the coil coincides with the direction of the arrow D1, and the second elastic force is applied to the locking claw portion when the coil is opened. 13 is given. The compression coil spring 21 is provided between the base portion 14 and the locking claw portion 13 so that the Z direction is the compression direction. The compression coil spring need not be connected to the base portion 14 and the locking claw portion 13. As described above, the elastic force imparting portion 17 can be used in place of the compression torsion coil spring 19 by constituting the elastic force imparting portion 17 with two members. In FIG. 13, the torsion coil spring 20 is disposed inside the compression coil spring 21, but the torsion coil spring 20 may be disposed outside the compression coil spring 21.

  Next, the clamping operation unit 5 will be described. The sandwiching operation portion 5 includes a base portion 22 and a cylindrical portion 23. FIG. 14 is a plan view of the clamping operation unit 5. In FIG. 14, the position of the clamping operation unit 4 with respect to the position of the clamping operation unit 5 in the bonded state is indicated by a two-dot chain line.

  The base portion 22 is a rectangular flat plate member provided on the opposing wall portion 8b of the other half-cracked body 3b. The base portion 22 may be a part of the opposing wall portion 8b of the other half cracked body 3b.

  The cylindrical portion 23 is a member that is erected on the base portion 22, and is erected in the direction of the arrow Z <b> 2 that is separated from the opposing wall portion 8 b when in the fitted state. In order to reduce the number of parts, the cylindrical portion 23 is preferably integrally formed with the base portion 22.

  The cylindrical portion 23 is a “blocking state releasing portion” in the present invention, and presses the locking claw portion 13 in the locked state in the direction of the arrow Z2 when the two half-cracks 3a and 3b are joined together. And it is a member which cancels | releases a locked state. In order to press the locking claw portion 13 in the direction of the arrow Z2 and reliably release the locked state, the inner diameter of the cylindrical portion 23 is larger than the outer diameter of the head portion 18a of the retaining portion 18 as shown in FIG. Also, the center axis of the cylindrical portion 23 coincides with the angular displacement center axis S in the attached state. The blocking state releasing part for releasing the locked state may be a mere protrusion, but if the pressed location is concentrated on one point, the locked state may not be released well, so It is preferable to form in a cylindrical shape. By forming it in a cylindrical shape, the pressed portion can be a portion surrounding the hole 13a in the locking claw portion 13, and the locked state can be reliably released.

  When using the anti-wrinkle device 2 including the clamping operation unit 5 and the clamping operation unit 4 configured as described above, first, the locking claw unit 13 is manually angularly displaced in the direction of the arrow D1. The lock state is assumed. Next, the anti-winding device 2 is disposed so that one of the grooves (groove 9a or groove 9b) of the two half-cracks 3a and 3b is along the branch line. At this time, among the longitudinal ends of the anti-winding device 2, the end portion close to the rope pinching device 1 is on the lower side in the vertical direction, and the end portion far from the rope pinching device is on the upper side in the vertical direction. The anti-winding device 2 is disposed. And the half crack body which is not along a branch line is angularly displaced, and the two half crack bodies 3a and 3b are united. By being attached, the two grooves 9 a and 9 b form an insertion hole 10, and a branch line is inserted into the insertion hole 10.

  When the two half-cracks 3a and 3b are joined, the cylindrical portion 23 presses the locking claw portion 13 in the direction of the arrow Z2 against the first elastic force by the elastic force applying portion 17, and this The lock state is released by. The locking claw portion 13 released from the locked state and brought into the unlocked state is angularly displaced in the direction of the arrow D <b> 2 by the second elastic force applied by the elastic force applying unit 17. The branch line inserted through the insertion hole 10 extends along the claw receiving wall portion 15 and is sandwiched between the claw receiving wall portion 15 and the claw receiving wall portion 15 that are angularly displaced.

  Therefore, according to the present invention, the anti-wrinkle device 2 is automatically operated by the clamping unit 6 including the clamping operation unit 4 and the clamping operation unit 5 by joining the two half-cracks 3a and 3b. Thus, the branch line can be sandwiched. In addition, when something is attached to the anti-winding prevention device 2 and the anti-winding prevention device 2 is displaced vertically downward by the load of the object, the locking claw portion 13 is moved in the direction of the arrow D1 due to friction with the branch line. As a result, the distance L between the side surface 13b of the locking claw portion 13 and the claw receiving wall portion 15 is reduced. At this time, the branch line, the elastic layer of the claw receiving wall portion 15 and the locking claw portion 13 are compressed, the frictional force between the locking claw portion 13 and the branch line is increased, and the anti-winding preventing device 2 is further dropped. Is prevented. That is, the rope pinching device 1 is configured to increase the pinching force and prevent the rope pinching device 1 from falling when the branch line is relatively vertically displaced in the direction in which the branch line extends. Has been.

  Further, the rope pinching device 1 is configured to pinch the branch line by the angular displacement of the locking claw portion 13, and therefore, of the surface of the locking claw portion 13 that faces the claw receiving wall portion 15. A branch line is pinched by a part. That is, the latching claw part 13 pinches a branch line locally. Therefore, since the clamping force is not dispersed, the branch line can be firmly clamped. Further, since the rope pinching device 1 is configured to pinch the branch line by the angular displacement of the locking claw portion 13, the hooking prevention device 2 is locked even if it is displaced vertically downward. The state in which the claw portion 13 locally clamps the branch line is maintained, and a firm clamping state can be maintained.

  Further, since the rope sandwiching device 1 is configured to sandwich the branch line by the angular displacement of the locking claw portion 13, it is not necessary to configure the rope sandwiching apparatus 1 long in the direction in which the branch line extends. The rope pinching device 1 can be reduced in size and the number of parts can be reduced.

  In the present embodiment, the claw receiving wall portion 15 is provided on one half-cracked body 3a as a part of the sandwiching operation portion 4, but as a modification of the present embodiment, the sandwiching operation portion 5 As a part, it may be provided in the other half cracked body 3b. FIG. 15 shows a rope sandwiching device 25 in which a claw receiving wall portion 24 is provided on the other half-cracked body 3b. In the rope sandwiching device 25, the claw receiving wall portion 24 and the side surface 13b of the locking claw portion 13 are opposed to each other only when the two half-broken bodies 3a and 3b are joined. At this time, the claw receiving wall portion 24 is provided at the same position as the above-described claw receiving wall portion 15. Therefore, similar to the above-described rope pinching device 1, the rope can be firmly and automatically pinched by the rope pinching device 25.

  Moreover, in this embodiment, although the cylindrical part 23 is provided in the other half crack body 3b as a part of clamping operation part 5, as a modification of this embodiment, a part of clamping operation part 4 is provided. As such, it may be provided on one half-cracked body 3a. FIG. 16 shows a rope sandwiching device 27 in which a cylindrical portion 26 is provided on one half-cracked body 3a. In this rope pinching device 27, when the two half-cracks 3a and 3b are joined, the end portion in the arrow Z1 direction of the cylindrical portion 26 is pressed by the base portion 22, and as a result, the locking claw portion 13 The locked state is released. At this time, the cylindrical portion 26 is provided at the same position as the cylindrical portion 23 described above. Therefore, similar to the above-described rope pinching device 1, the rope can be firmly and automatically pinched by the rope pinching device 27. In addition, in this rope pinching apparatus 1, the base 22 is a “blocking state release unit” in the present invention. Furthermore, when the base 22 and the other half-cracked body 3b are integrally formed, the other half-cracked body 3b becomes a “blocking state releasing portion”.

  Further, in the present embodiment, the claw receiving wall portion 15 is the “claw receiving portion” in the present invention, but as a modified example of the present embodiment, the second locking is configured similarly to the locking claw portion 13. The nail portion may be a “nail receiving portion”. FIG. 17 shows a rope pinching device 29 using the second locking claw portion 28 as a claw receiving portion. The rope pinching device 29 has a second cylindrical portion 30 configured similarly to the cylindrical portion 23 in order to release the locked state of the second locking claw portion 28. In the rope pinching device 29, when the two half-cracks 3a and 3b are joined, the locking claw portion 13 is pressed by the cylindrical portion 23 to release the locked state, and the angular displacement is performed in the direction of the arrow D2. At the same time, the second locking claw portion 28 is pressed by the second cylindrical portion 30 to release the locked state, and is angularly displaced in the direction of the arrow D3. Then, a part of the surface facing the second locking claw portion 28 of the locking claw portion 13 angularly displaced in the direction of the arrow D2 and the second locking claw portion 28 angularly displaced in the direction of the arrow D3. The branch line is clamped by a part of the surface facing the locking claw 13. Therefore, this rope pinching device 29 can pinch a branch line locally, and can pinch a branch line firmly and automatically like the rope pinching apparatus 1 described above.

  In the rope pinching device 29, the hinge portion is arranged so that the cylindrical portion 23 and the second cylindrical portion 30 come into contact with and press the locking claw portion 13 and the second locking claw portion 28 almost simultaneously at the time of attachment. It is preferable that the axial length of the second cylindrical portion 30 disposed on the outer side in the angular displacement centering on 7 is longer than the axial length of the cylindrical portion 23 disposed on the inner side.

  Next, the rope pinching device 34 which is 2nd Embodiment of this invention is demonstrated. FIG. 18 is a view showing the rope pinching device 34 and corresponds to FIG. The rope pinching device 34 includes two half-breaking bodies 3a and 3b and a pinching operation portion 35 provided in the recess 11a of the half-breaking body 3a. The half-cracked body 3a is a support member according to the present invention, and the groove 9a of the half-cracked body 3a is a groove into which a branch line (strand) of a utility pole can be fitted.

  FIG. 19 is an exploded perspective view of the clamping operation unit 35 and corresponds to FIG. The clamping operation part 35 includes a locking claw part 13, a base part 14, a claw receiving wall part 15, an angular displacement shaft part 16, an elastic force applying part 17, a retaining part 18, and a pressed part 36. including.

  The pressed portion 36 is a columnar member connected to a part of the side surface 13b of the locking claw portion 13 on the arrow Z2 direction side, and is provided to extend perpendicularly to the Z direction. The pressed portion 36 is provided so as to be positioned between the locking claw portion 13 and the claw receiving wall portion 15 when the locking claw portion 13 is in the locked state, and the locking claw portion 13 is locked. When the state is released and the angle is displaced, the claw receiving wall portion 15 is provided so as not to contact. Here, the pressed portion 36 connected to the locking claw portion 13 may be configured by fixing a member different from the locking claw portion 13 to the locking claw portion 13. 13 (claw body 13d) may be formed integrally.

  A method of using the rope pinching device 34 including the pinching operation portion 35 configured as described above will be described with reference to FIGS. 20 and 21. 20 is a view corresponding to FIG. 7, and FIG. 21 is a cross-sectional view taken along line EE of FIG.

  When using the rope pinching device 34, first, the locking claw portion 13 is manually angularly displaced in the direction of the arrow D1 to be in a locked state. Next, as shown in FIG. 20 (a), the rope sandwiching device 34 is installed so that the branch line W1 fits into the groove 9a of the half-cracked body 3a. At this time, it installs so that the to-be-pressed part 36 may be pressed in the arrow Z2 direction with the branch line W1. As a result, as shown in FIG. 21, the locking claw portion 13 in the locked state moves in the direction of the arrow Z2, and the locked state is released. The locking claw portion 13 released from the locked state and brought into the unlocked state is angularly displaced in the direction of the arrow D <b> 2 by the second elastic force applied by the elastic force applying unit 17. The branch line W1 that fits into the groove 9a extends along the claw receiving wall 15 and is sandwiched between the angularly displaced locking claw 13 and the claw receiving wall 15 as shown in FIG. Worn.

  Note that, as shown in FIG. 20B, in the sandwiched state of the branch line W1, the pressed portion 36 is not in contact with the branch line W1, and as a result, the first elastic force applied by the elastic force applying unit 17 is obtained. Accordingly, the locking claw portion 13 is moved in the direction of the arrow Z1. Therefore, the elastic force imparting portion 17 is in a state in which the compressive force in the Z direction is slightly released and slightly extended in the Z direction when the branch line W1 is sandwiched.

  After pinching the branch line W1, the half-cracked body 3b is angularly displaced, and the two half-cracked bodies 3a and 3b are joined together. By joining, the two grooves 9a and 9b form an insertion hole 10, and the branch line W1 is inserted into the insertion hole 10.

  As described above, according to the present invention, the rope sandwiching device 34 automatically sandwiches the branch line W1 by the sandwiching operation portion 35 by fitting the branch line W1 into the groove 9a of the half-cracked body 3a. Can be worn. Further, when something is attached to the rope pinching device 34 and the rope pinching device 34 is displaced vertically downward by the load of the thing, the locking claw portion 13 is caused to move by the friction with the branch line W1. As a result, the distance L between the side surface 13b of the locking claw portion 13 and the claw receiving wall portion 15 is reduced. At this time, the elastic layer of the branch line W1, the claw receiving wall part 15 and the locking claw part 13 is compressed, and the frictional force between the locking claw part 13 and the branch line W1 is increased. Further fall is prevented. That is, the rope pinching device 34 increases the pinching force when the branch line W1 is relatively vertically displaced in the extending direction of the branch line W1, and prevents the rope pinching device 34 from falling. It is configured.

  In the present embodiment, the pressed portion 36 is connected to a part of the side surface 13b of the locking claw portion 13 on the arrow Z2 direction side, but as a modified example of the present embodiment, the pressed portion 36 is It may be provided over the entire portion of the side surface 13b of the locking claw portion 13 on the arrow Z2 direction side. FIG. 22 shows a rope sandwiching device 38 in which a pressed portion 37 is provided over the entire portion of the side surface 13b of the locking claw portion 13 on the arrow Z2 direction side. FIG. 22 corresponds to FIG.

  In the rope pinching device 38, the pressed portion 37 is provided over the entire portion of the side surface 13b of the locking claw portion 13 on the arrow Z2 direction side, and the locked state of the locking claw portion 13 is released. It is provided so as not to come into contact with the claw receiving wall 15 when the angular displacement occurs. In the rope sandwiching device 38 configured as described above, the pressed portion 37 comes into contact with the branch line W1 in the sandwiched state of the branch line W1, and as a result, the elastic force applying unit 17 does not release the compressive force. . When the elastic force imparting portion 17 extends in the Z direction, the pinching force decreases. However, in the rope pinching device 38, the compression force is not released, so the pinching force does not decrease, and thereby the branch line W1 is pinched more firmly. Can be worn.
