JP4825192B2 - A sluice with a lifting rod buckling prevention device - Google Patents

Description

  The present invention relates to a sluice equipped with a lifting rod buckling prevention device.

  The switch suitable for a sluice with a structure that raises and lowers the door body along the left and right gate pillar guides is a gate beam that connects the left and right gate pillars with a spindle or rack or other lifting rod connected to the upper edge of the door body. The drive mechanism installed in the main component is the main component.When the lifting rod is pulled up by the drive mechanism, the door body rises to the open position. Conversely, when the lifting mechanism is pushed down by the drive mechanism, the door body is closed. Lower to position.

  However, when closing the sluice, if the drive device does not stop simultaneously with the bottom of the lower side of the door body, a force in the compression direction acts on the lifting rod, causing buckling of the lifting rod.

  Therefore, a guide bar that extends vertically with a rack (lifting bar) sandwiched between the left and right roller guide grooves (gate post guides) is formed, and a sliding hole is formed through which the guide bar and the rack can be moved up and down relatively. A rack bar buckling prevention girder has been proposed in which a support girder is arranged on the upper side of the door body and a support fitting capable of contacting the lower surface of the girder is attached to the lower end portion of the rack (for example, Patent Document 1). reference).

In this rack bar buckling prevention girder, the girder always positioned above the roller guide groove suppresses the deflection of the guide bar when the door body is bottomed. Push up the receiving girder to secure the door ascent.

  Rollers 4 are attached to the left and right side end surfaces of the door body 1, and the rollers 4 roll along side rails 5 embedded in the guide portion 3.

  The opening / closing machine mainly includes a pair of elevating rods 6 such as spindles or racks whose lower ends are connected to the left and right sides of the upper side of the door body 1, and a drive mechanism 8 installed on a beam 7 connecting the left and right gate columns 2. When the elevating rod 6 is pulled up by the drive mechanism 8, the door body 1 is raised to the open position, and when the elevating rod 6 is pushed down by the drive mechanism 8, the door body 1 is lowered to the closed position.

  The lifting rod buckling prevention device is fitted on the left lifting rod 6 so as to be movable relative to the left and right lifting rods 6, and can move up and down along the guide portion 3 of the left portal 2, and prevents the door body 1 from being lifted and lowered. A left pedestal 10 that can be attached to the left gate column 2 and can hold the left support 9 at a predetermined height, a left pressing member 11 that is attached to the door 1 so that the left support 9 can be pushed up, A right support 9 which is externally fitted to the elevating rod 6 so as to be movable relative to the vertical and which can be raised and lowered along the guide portion 3 of the right portal 2, and which is attached to the right portal 2 so as not to prevent the door 1 from being raised and lowered; The right pedestal 10 capable of holding the right support 9 at a predetermined height, the right pressing member 11 attached to the door 1 so that the right support 9 can be pushed up, and the horizontally extending left and right supports 9 are integrated. And a connecting member 12 connected to the left and right support bodies 9, the gantry 10, and Pressing member 11 is essentially as a symmetrical shape.

  The support body 9 includes a first member 14 having a hole 13 through which the elevating rod 6 is inserted, a second member 16 in which the elevating rod 6 is fitted in the long groove 15 in a concave shape in plan view, and the gantry A third member 17 attached to the second member 16 so as to be in contact with the upper surface of the tenth member, and a fourth member 18 attached to the second member 16 so that the pressing member 11 can be in contact with the lower surface. And a fifth member 19 that is bolted to the second member 16 so that the position of the second member 16 can be adjusted to the left and right. The second and fifth members 16 and 19 have recesses 20 and 21 that fit into the side rail 5. Is formed.

  The connecting member 12 is obtained by attaching plates 22 bolted to the second member 16 to both end portions of the hollow rod 23, suppressing tilting of the support 9 with respect to the lifting rod 6, and lifting and lowering. It plays the role which prevents that the support body 9 displaces to the circumferential direction of the stick | rod 6. As shown in FIG.

  When the door body 1 is lifted from the closed position where the lower side is bottomed as shown in FIG. 1, the left and right pressing members 11 eventually come into contact with the fourth members 18 as shown in FIG. As shown in FIG. 3, the third members 17 are separated from the left and right bases 10, and the left and right supports 9 and the connecting member 12 are integrally raised with the door body 1.

  Until the pressing member 11 comes into contact with the fourth member 18 and the support body 9 begins to rise, each lifting rod 6 slides upward in the hole 13 of the first member 14.

  Further, after the pressing member 11 comes into contact with the fourth member 18, the recesses 20 and 21 of the second and fifth members 16 and 19 slide upward along the side rail 5.

  Therefore, the door body 1 can be raised until the support body 9 reaches the uppermost end of the guide portion 3 of the gate pillar 2.

  When the door body 1 is lowered from the open position, the left and right support bodies 9 and the connecting member 12 also follow and descend, and eventually the third members 17 simultaneously contact the left and right bases 10 as shown in FIG. The support body 9 and the connecting member 12 are stopped, and only the door body 1 and the lifting bar 6 continue to descend.

  The concave portions 20 and 21 of the second and fifth members 16 and 19 slide downward along the side rail 5 until the third member 17 comes into contact with the gantry 10 and the support body 9 stops.

  In addition, after the third member 17 comes into contact with the gantry 10, each elevating rod 6 slides downward in the hole 13 of the first member 14.

  Therefore, the support body 9 can be lowered to the middle in the height direction of the gate pillar 2 that is the attachment portion of the gantry 10, specifically, to the middle of the range in which the upper side of the door body 1 moves up and down.

  That is, when the lower side of the door body 1 is bottomed, the distance from the upper side of the door body 1 to which the lower end portion of the elevating bar 6 is connected to the support body 9 through which the elevating bar 6 penetrates does not extend too much. The buckling of the elevating bar 6 can be effectively suppressed.

  FIG. 6 shows another example of the sluice equipped with the lifting rod buckling prevention device of the present invention. The lifting rod 6 is intended for one switch, and the same reference numerals as in FIGS. The parts marked with indicate the same thing.

  The lifting rod buckling prevention device includes a left support 24 that can be moved up and down along the guide portion 3 of the left portal 2, and a left support 24 that is attached to the left portal 2 so as not to prevent the door 1 from moving up and down. A left pedestal 10 that can be held at a height, a left pressing member 11 that is attached to the door 1 so that the left supporting member 9 can be pushed up, and a right supporting member 24 that can be moved up and down along the guide 3 of the right portal 2. The right frame 10 is attached to the right gate 2 so as not to hinder the raising and lowering of the door 1 and the right support 24 can be held at a predetermined height, and the right support 9 is attached to the door 1 so that the right support 9 can be pushed up. The right pressing member 11 and a connecting member 25 that is externally fitted to the elevating bar 6 and integrally connects the left and right support bodies 24 are provided. The left and right support bodies 24, the gantry 10, and the pressing member 11 are basically symmetrical. As a shape.

  The support 24 includes a first member 26 extending horizontally from the guide portion 3 to the vicinity of the lifting rod 6 and a second member 27 attached to the first member 26 so as to be in contact with the upper surface of the gantry 10. A third member 28 attached to the first member 26 so that the pressing member 11 can contact the lower surface, and a fourth member 29 bolted to the first member 26 so that the position of the first member 26 can be adjusted to the left and right. The first and fourth members 26 and 29 are formed with recesses 30 and 31 that fit into the side rails 5.

  The connecting member 25 has a hole 32 through which the elevating rod 6 is inserted, and is bolted to an end portion of each support body 24 near the elevating rod 6, and the support body 24 is inclined with respect to the elevating rod 6. It plays a role to suppress things.

  When the door body 1 is lifted from the closed position, the left and right pressing members 11 come into contact with the third members 28 at the same time to push up the left and right support members 24, and the second members 27 are separated from the left and right mounts 10. The left and right support bodies 24 and the connecting member 25 are raised integrally with the door body 1.

  Until the pressing member 11 comes into contact with the third member 28 and the support 24 starts to rise, the elevating rod 6 slides upward in the hole 32 of the connecting member 25.

  Further, after the pressing member 11 comes into contact with the third member 28, the concave portions 30 and 31 of the first and fourth members 26 and 29 slide upward along the side rail 5.

  Therefore, the door 1 can be raised until the support 24 reaches the uppermost end of the guide portion 3 of the gate pillar 2.

  When the door body 1 is lowered from the open position, the left and right support bodies 24 and the connecting member 25 are also moved downward, and eventually the second members 27 are simultaneously brought into contact with the left and right mounts 10 and the left and right support bodies 24 and The connecting member 25 stops and only the door body 1 and the lifting bar 6 continue to descend.

  The concave portions 30 and 31 of the first and fourth members 26 and 29 slide downward along the side rail 5 until the second member 27 comes into contact with the gantry 10 and the support 24 stops.

  Further, after the second member 27 comes into contact with the gantry 10, the elevating rod 6 slides downward in the hole 32 of the connecting member 25.

  Therefore, the support body 24 can be lowered to the middle in the height direction of the gate pillar 2 that is the attachment portion of the gantry 10, specifically, to the middle of the range in which the upper side of the door body 1 moves up and down.

  That is, when the lower side of the door body 1 is bottomed, the distance from the upper side of the door body 1 to which the lower end portion of the lifting bar 6 is connected to the connecting member 25 through which the lifting bar 6 penetrates does not extend too much. The buckling of the elevating bar 6 can be effectively suppressed.

  Further, the left and right support members 24 may be integrally connected without using the connecting member 25. As an example, the lift rods 6 have a concave shape in plan view at the ends of the support members 24 near the lift rods 6. 5 is formed like the second member 16 in FIG. 5, and the end portions of the support members 24 near the lifting bar 6 are overlapped with each other so that both long grooves surround the lifting bar 6 in the circumferential direction. And bolt fastening can be considered.

  In addition, the sluice equipped with the lifting rod buckling prevention device of the present invention is not limited to the above-described embodiment, but slides along the side rails on the left and right side end surfaces of the door body instead of the rollers. Needless to say, the present invention can be applied to a sluice equipped with a possible sliding shoe and can be modified without departing from the gist of the present invention.

  The sluice equipped with the lifting rod buckling prevention device of the present invention can also be applied to an existing sluice.
