Description

  The present invention relates to a support device that is mounted on a pallet used for cargo handling and can be suspended without bending the surface of the pallet.

  As a cargo handling pallet, a basic structure in which rectangular flat plates arranged in parallel on the front and back surfaces and girders are applied to the middle portions of the front and back surfaces is widely known. In general, the two forks of the forklift are inserted into the space formed by the girders, and the pallet is moved up and down. Moreover, since it is necessary to load a heavy material also as a material which comprises a pallet, the structure using stronger materials, such as a synthetic resin and an aluminum material, is also proposed.

  By the way, in order to use the pallet for cargo handling not only with a forklift, but also with a forklift, a ring-shaped attachment is attached to the four corners of the pallet and hooks are attached to the tip of the attachment. A method of hooking the provided wire rope and suspending it with a crane device is also widely adopted.

JP 2000-159474 A

  Patent Document 1 was previously invented by the applicant. A supporting material such as a pipe is passed through both sides of the pallet, and a hook at the tip of the wire is hung on a rotatable retaining ring provided at both ends thereof. It is the structure to do. And the detent material for fixing the distance of two support materials is spanned to the support material so that it may not approach the center part when the support material is suspended by the wire.

  However, in the configuration described in Patent Document 1, the distance between the support members can be reliably fixed if the load is relatively light. However, when a heavy load is loaded, the pallet bends and thereby the support member. Will tilt somewhat inward depending on the deflection. If it does so, there existed a problem that the offset stop material will remove | deviate by the inclination of the support material of both sides.

  An object of the present invention is to solve such a conventional problem, and an object of the present invention is to provide a pallet support device that can stably transport a pallet even when a heavy object is loaded on the pallet.

  In order to achieve the above-described object, the present invention is a support device applied to both sides where a through hole of a cargo handling pallet appears. A plurality of positioning holes are arranged in parallel on both sides, and the positioning holes on both sides are sandwiched by a pair of steel plates from above and below to achieve an object. The two square pipes are for lifting both sides of the pallet when the pallet is suspended by an equal pulling force, and the positioning holes are configured to set the two square pipes so that they are not biased. In addition, the pair of steel plates is configured to securely fix each positioning hole, and at the same time, corrects the deformation of the pallet in the bending direction due to the load loaded on the pallet surface. That is, since the positioning hole is sandwiched between a pair of steel plates and the position in the rotational direction is restricted, the movement of the square pipe inserted through the positioning hole is also restricted thereby.

Furthermore, a means of including a steel plate above each positioning hole and drilling a screw hole was selectively used. As a result, the square pipe is not restricted from moving in the insertion direction, so that the square pipe is not inadvertently dropped off, and a solid frame is formed by the two square pipes and a pair of support devices, which may cause twisting. It also has a strong proof strength. When adopting a means for providing a handle at the center of the upper steel plate, it is easy to transport a relatively heavy support device.

Furthermore, a means of further providing a reinforcing wall surface of a steel plate at the middle part of the positioning holes on both sides was used. This reinforcing wall surface acts so as to receive stress in the bending direction of the support device, and reliably prevents the support device from bending.

  According to the present invention, the pallet support device sandwiches a plurality of through holes provided in parallel on both sides between two upper and lower steel plates, so that the square member inserted through the pallet is securely fixed even when a heavy object is loaded. It is possible to reinforce the bending of the pallet itself, and the support device does not come off the square bar. Therefore, a safe pallet support device could be provided.

The perspective view which shows the state which mounted | wore the pallet with the support apparatus of this invention, inserted the square material in the pallet, and was suspended with the wire. The exploded perspective view of a pallet and a support device. The front view of the support apparatus of this invention. FIG.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is an exploded perspective view showing a state in which a support device of the present invention is attached to a known pallet. Here, 1 is a pallet main body, which is composed of front and back plates 2 and 3 and a girder 4. Since the pallet body is not a component in the present invention, it is sufficient if the pallet body is a known pallet and the through holes 5 are formed in the depth direction between the front and back surfaces 2 and 3. Reference numerals 6 and 6 denote square pipes which are inserted into the through holes 5 of the pallet main body 1, and two of them are inserted into the through holes 5 of the pallet main body 1 in parallel. Reference numeral 7 denotes a ring-shaped retaining ring that functions as a wire locking portion provided at both ends of the square pipe 6, and may be configured to be rotatable or non-rotating. Then, the wires 8 to 8 are hung on the retaining ring 7 appearing at the four corners and suspended by a crane device (not shown) or the like.

  The square pipes 6 and 6 are inserted in parallel on both sides of the through hole 5 of the pallet 1 and then positioned by the support device 9 of the present invention. As shown in detail in FIGS. 3 and 4, the support device 9 has four positioning holes 10... 10 on both sides. More specifically, the positioning hole 10 is obtained by cutting a square pipe formed by drawing with a uniform width. However, the method of manufacturing the positioning hole 10 is not limited to this, and it can be manufactured by a known method as long as it has a structure having an inner diameter that allows the square pipe 6 to be inserted tightly. Then, in a state where four positioning holes 10 are arranged on both sides, the upper and lower sides are sandwiched and connected by steel plates 11 and 11 and fixed by welding or the like as an example. In the present embodiment, four positioning holes 10 are provided on both sides, but the meaning of providing the positioning holes 10 is to appropriately determine the distance between the square pipes 6 and 6 depending on the position where the square pipe 6 is inserted. Therefore, it is not necessary to limit the number to 4. Further, the positioning hole 10 does not simply mean “hole” but refers to a concept including a peripheral frame part for forming this hole, and has a physical width. Further, a steel plate having a width commensurate with the width of the positioning hole 10 is also adopted for the steel plate 11. However, it is not necessary to make the width of the positioning hole 10 and the width of the steel plate 11 exactly match. Reference numeral 12 denotes a handle for carrying. As a basic configuration, the positioning holes 10 provided on both sides and the steel plates 11 and 11 are sufficient, but in order to reinforce the bending strength, in this embodiment, the steel material is placed between the innermost positioning holes 10a. Reinforcing wall surfaces 13 are provided on the front and rear sides. Accordingly, the central portion of the support device 9 has a rectangular shape with a vertically long cross section. A screw hole 14 is formed by including a steel plate 11 in the upper part of the positioning hole 10 corresponding to each positioning hole 10. The screw 15 is fitted into the screw hole 14 with the square pipe 6 inserted, and the square pipe is inserted. By tightening 6, the square pipe 6 is fixed so as not to move.

  In the case of using the apparatus configured as described above, first, the square pipes 6 and 6 are inserted into the through-holes 5 inside the pallet 1, and each is placed on both sides in the width direction of the pallet 1. Next, the support device 9 of the present invention is adapted to the place where the square pipes 6 and 6 are protruding from the pallet 1, and the square pipes 6 and 6 are inserted into the positioning holes 10. In this case, as to which of the four positioning holes 10 the square pipe 6 is inserted into, the positioning holes 10 that are in the same position are determined so as not to tilt when the square pipes 6 and 6 are suspended by wires or the like. . After the square pipes 6 and 6 are inserted into the positioning holes 10 of the support devices 9 and 9 on both sides, the screw 15 is engaged with an internal screw formed in the screw hole 14 in advance. Thereafter, the wire is hooked on the retaining ring 7 provided at both ends of the square pipe 6 to complete the operation.

  In the present embodiment, when a load is loaded on the surface plate 2 of the pallet 1, a frame is formed by the pair of support devices 9 and 9 and the pair of square pipes 6 and 6 even when these loads are relatively heavy. Therefore, since the load applied to the pallet 1 is received by this frame, the pallet 1 does not bend unnecessarily.
