  TECHNICAL FIELD The present invention relates to a retaining member for retaining a retaining member such as a retaining strap for a granular storage bag for storing granular material such as excavated earth and sand and grains, and a granular material guide provided with the retaining member. It is.

Conventionally, when filling and storing the excavated earth and sand in the foundation work of a building in a bag, or when making large sandbags by adding earth and sand to the bag, the bag body makes it easier to add earth and sand Must be held open. Two or more workers are required to open the opening of the bag body with the hands of workers, and when using heavy machinery to throw in a large amount of earth and sand, close to the bag body. There was a problem that it was dangerous for the workers.
Therefore, various techniques have been developed as techniques for holding the bag body in an open state without using the hands of the operator.

(Patent Document 1) “A rectangular parallelepiped frame that accommodates a bag body, and a latching portion that is disposed on an upper portion of the frame, and the latching portion is horizontally attached to the upper portion of the frame. A bag holding comprising: a cylinder, a round bar rotatably provided in the cylinder, a handle projecting at one end of the round bar, and a hanging part projecting from the other end of the round bar "Frame" is disclosed.
(Patent Document 2) states that “a frame that houses a bag, a clamp that is detachably fixed to the frame, two opposing pin holding plates that protrude from the clamp, and the pin Opening fixing of a residual soil storage bag comprising a pin member having a head larger than a through-hole formed in a holding plate and detachably hooking a hooking string attached to an opening end of the bag body ”Is disclosed.
Utility Model Registration No. 3047887 JP 2005-82209 A

However, the above conventional techniques have the following problems.

When filling the powder body 25 into the bag body 21, first, as shown in FIG. 3, both ends are hooked to the upper hooking member 6 of the powder body guide tool 1 in the place where the powder body 25 is filled. A hook 24 a is hung on the hooking member 20, and the granular material guide 1 is slightly lifted to open a gap between the floor surface and the lower end of the lower cylindrical body 4, and the bag body 21 extends below the lower cylindrical body 4 from this gap. And the lower cylinder 4 is inserted into the opening 22 of the bag body 21, and the respective hooking bodies 23 are hung on the hooking portions 16 on the upper edges of the overlapping portions 14 of the respective hooking members 10. Next, the detachment prevention member 8 is hooked on the hooking portion 15.
Next, as shown in FIG. 4, after the granular material guide 1 is suspended and placed on the floor surface, the hook 24 a is removed from the hooking member 20. Next, the granular material 25 such as earth and sand or grains is sown with the bucket 24, and the bucket 24 is moved above the granular material guide 1, and then the bucket 24 is tilted to guide the granular material 25 with the granular material. The tool 1 is put into the cylinder 2.
Next, as shown in FIG. 5, when the powder guide body 1 is lifted by hooking the hook member 24 to the hooking member 20 again, the powder body 25 put into the cylinder 2 is contained in the bag body 21. Fall into. The powder body 25 dropped into the bag body 21 applies a load from the powder body 25 to the latching body 23 of the bag body 21, but the latching body 23 is the latching section 16 at the upper edge of the overlapping portion 14. Since the hooking portion 23 is hooked and the abutting portion 17 formed on the back surface of the hooking portion 16 is in contact with the upper edge of the base side of the support member 11, the base portion of the hooking body 23 is substantially cylindrical. 2 is hung on the base side of the support member 11 fixed by welding or the like, and can withstand the load of the granular material 25.

The movable body can be moved, and the bag body can be lifted or pulled laterally. When removing the latching body 23 from the support member 11, simply hold the tip end side of the lever 13 and rotate it downward, the latching body 23 is flipped up at the overlapping portion 14, and the latching body 23 is moved to the lever 13. It can be removed from the tip side. For this reason, it has a high mechanical strength that can withstand the load of the bag body 21 filled with the granular material 25, and the suspending body 23 can be removed with a slight force and a simple operation by the principle of the lever. Excellent.
(2) Since the upper surface of the latching portion 16 fixed to the upper edge of the overlapping portion 14 of the lever 13 protrudes, the latching body 23 latched by the latching portion 16 is difficult to wear and difficult to cut. Further, when the lever 13 is rotated downward by holding the front end side of the lever 13 and the latching body 23 is flipped up by the overlapping portion 14, the latching body 23 easily slides on the upper surface of the latching portion 16 and can be easily removed. .
(3) Since the length of the overlapping portion 14 on the base side of the lever 13 is shorter than the length from the pivot 12 to the tip of the lever 13, hold the tip of the lever 13 and rotate the lever 13 downward. Since the length of the force point from the fulcrum (the pivot 12) is longer than the length from the fulcrum (the pivot 12) to the action point (the position of the latch 23) when the latch 23 is moved up, the length of the force point is small. The lever 13 can be rotated with a sufficient force.
(4) Since the abutting portion 17 that abuts the upper edge of the support member 11 is provided on the upper edge of the lever 13, the lever 13 is removed when the latching body 23 hung on the base side of the support member 11 is removed. Can rotate only in one direction on the lower side, there is no operation error, and the lever 13 can be flipped up and the latching body 23 can be reliably removed.
(5) Since the locking member 8 having a locking member at the tip is fixed to the cylindrical body 2, the locking member of the locking member 8 is hooked on the support member 11 after the locking body 23 is hung on the support member 11. By being attached to 15, even when the moving body (cylinder body 2) is moved, even if the hooking body 23 is displaced outward, it can be prevented from coming off, and the safety is excellent.

Moreover, since the granular material guide provided with the latching member in Embodiment 1 of this invention is comprised as mentioned above, the following effects | actions are acquired.
(1) Since the base portion of the support member 11 is fixed to the symmetrical position of the outer surface of the cylindrical body 2, the opening 22 of the bag body 21 is covered from the lower part of the cylindrical body 2 at the place where the granular material 25 is charged, When the latching body 23 of the bag body 21 is latched on the latching section 16 on the base side of the lever 13, the bag body 21 can be held in an open state, and when the granular material 25 is introduced from the upper part of the cylindrical body 2. The granular material 25 is filled in the cylindrical body 2. Next, when the cylindrical body 2 is lifted upward, the granular material 25 in the cylindrical body 2 is introduced into the bag body 21 and can be moved laterally to a desired position while being lifted. After being placed at a desired position, the holding member 23 is flipped up at the overlapping portion 14 and moved to the tip side of the lever 13 simply by holding the tip side of the lever 13 of the latch member 10 and rotating it downward. Can be made. Next, when the cylindrical body 2 is lifted upward, the latching body 23 is detached from the lever 13 and the cylindrical body 2 is separated from the bag body 21, so that the cylindrical body 2 is moved to the place where the powder body 25 is charged, A new bag 21 can be put on and the powder 25 can be charged. In this way, the latching body 23 can be removed from the support member 11 by a very simple operation of rotating the lever 13 in a short time, and the bag body 21 filled with the granular material 25 is attached to the cylindrical body 2. Since it is moved and placed in the horizontal direction while being hung, there is no need for incidental work such as changing the hooking body 23, so the productivity of the work of filling the powder body 25 into the bag body 21 can be increased. . When actually performing the work, a series of work of filling the bag body 21 with the powder body 25 and laterally moving and placing the bag body 21 filled with the powder body 25 to a desired position is performed for 2 minutes at a time. It was found that it can be done with this cycle. This indicates that 30 filling operations can be performed per hour, and it has been found that 1.5 times higher productivity can be obtained as compared with the conventional technique.
(2) Since both ends of the support members 11 and 11 are fixed to the back side of the support member 11 and the pipe-shaped reinforcement member 3a is provided in the cylinder 2, the cylinder 2 is suspended from the support members 11 and 11. It is difficult to compress and deform due to the weight of the bag body 21 and is excellent in durability.

As described above, since the latching member according to the second embodiment of the present invention is configured, the following operation is obtained.
(1) The lever 33 is formed of a pipe material or a steel bar whose cross section in the short direction is formed in a substantially circular shape, and since the latching portions 35 and 35a protrude from the bay, the latching portions 35 and 35a A latching body (not shown) to be hung can be made difficult to cut, and when the lever 33 is rotated downward by holding the distal end side of the lever 33 and the latching body jumps up at the overlapping portion 34, the latching body of the lever 33 Since the upper surface is easy to slide, it can be easily removed.
(2) Since the lower edge of the lever 33 is provided with the abutting portion 36 that is locked to the lower edge of the support member 31, when the unillustrated latching body hung on the support member 31 and the overlapping portion 34 is removed, Since the lever 33 can be rotated only in one direction on the lower side, there is no operation mistake, and the lever 33 can be flipped up to reliably remove the latching body.

(Embodiment 3)
FIG. 9A is a perspective view of a movable body to which a latching member according to Embodiment 3 of the present invention is fixed, and FIG. 9B shows a state after the latching member according to Embodiment 3 is rotated. It is a perspective view, (c) is a side view of the latching member in Embodiment 3.
In the figure, 40 is a latching member according to Embodiment 3 of the present invention, 41 is a movable body made of a bottomed cylindrical container made of steel or the like, 42 is a plate-like member or the like and is welded or the like. A support member having a base fixed symmetrically on both sides of the movable body 41 by welding or the like, 43 is a pivot shaft such as a bolt inserted into a through-hole drilled in the distal end side of the support member 42, and 44 is a base side A lever 45, which is formed of a plate-like member whose width is substantially the same as or slightly narrower than the width of the support member 11 and is rotatably fixed by the pivot 43, overlaps the support member 11 on the base side of the support member 11 with respect to the pivot 43. The overlapping portion 46 of the lever 44 is formed of a half-cracked pipe material or the like, is disposed and fixed on the lower edge of the overlapping portion 45, and a latching portion 47 on which a latching body 48 described later is latched, and 47 is a latching portion 46. This is a contact portion formed on the back surface of the lever, and the lever 44 is rotated around the pivot 43. When this is done, the contact portion 47 contacts the lower edge of the base side of the support member 42. Reference numeral 48 denotes a hooking body such as a wire having both ends formed in an annular shape.

  As in the case described in the first embodiment, the hook member in the third embodiment of the present invention configured as described above is a heavy machine such as a crane by hanging the hook body 48 on the hook portion 46. The latching body 48 can be lifted to lift or move the movable body 41. When the latching body 48 is removed from the latching portion 46, the lever 44 is held upward and rotated upward. The latch body 48 can be lifted up by the latch body 48 to remove the latch body 48 from the tip end side of the lever 44.

As described above, since the latching member according to the third embodiment of the present invention is configured, the following operation is obtained.
(1) Since the support member 42 whose base is fixed to the moving body 41 substantially bears the load of the moving body 41 suspended by the hanging body 48, the supporting member 42 has high mechanical strength and has high hanging strength. At the time of attaching / detaching the stop body 48, the latch body 48 can be removed with a slight force and a simple operation to rotate the lever 44 according to the principle of the lever, and the workability is excellent.

  In the present embodiment, the case where the latching member 40 is fixed to the movable body 41 made of a bottomed cylindrical container has been described. However, lifting, hanging, lateral pulling, etc. are performed by heavy equipment such as a crane or an excavator. The moving member is not particularly limited as long as it can be moved. For example, the hooking member 40 can be fixed to a moving body such as mechanical equipment or a jig, and the same action can be obtained in this case.

  TECHNICAL FIELD The present invention relates to a latch member for latching a retaining strap of a granular material storage bag for storing granular materials such as excavated earth and sand and grains, and a granular material guide provided with the latch member. Because it has high mechanical strength that can withstand the load applied by the hanging body, it can be lifted or pulled horizontally using heavy machinery, etc. It is possible to provide a latching member that can remove the latching body and is excellent in workability, and it is possible to remove the latching body such as a flexible container bag in a short time, and the bag is filled with powder particles. Since the body can be moved in the horizontal direction with the body suspended, no additional work such as changing the retaining body is required to move the bag body, so the productivity of filling powder into the bag body is unnecessary. It is possible to provide a granular material guide that can increase the resistance.
