[0002] A forklift is a device for lifting and transferring workpieces. A forklift can replace manpower to transfer large workpieces. When a forklift is used, it is often necessary to first stably clamp the workpiece through a forklift clamp, and then connect the forklift clamp to the forklift to ensure the stability and safety of the forklift handling. The folding box here mainly refers to a folding container, which is a container that can simply fold the main components of the container. When carrying goods, it is often necessary to fold and stack the empty folding containers to save space and reduce the transportation cost. Pin holes are respectively provided at the four corners of the top plate and the bottom plate of the folding container, so that it is convenient to fix them by pins when stacking. After some types of folding containers are folded, the pin holes are still located at the top four corners of the folded box body. The existing forklift clamp often includes two clamps, which are clamped together to clamp the folding box. This not only has high requirements on the stability and clamping degree of the clamps, but also does not utilize the original pin hole structure of the folding container. Utility Model Content

[0016] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0017] like Figures 1 to 4As shown, it is a schematic diagram of the structure of the forklift clamp for folding boxes provided by the utility model. The forklift clamp for folding boxes includes a crossbar assembly 10 and clamp bodies 20 respectively arranged at both ends of the crossbar assembly 10. The forklift clamp for folding boxes also includes some other functional modules, such as a connection structure arranged between the crossbar assembly 10 and the clamp body 20, etc., which should be well known to those skilled in the art and will not be described in detail here.

[0018] The crossbar assembly 10 includes a crossbar 11, two vertical bars 12 symmetrically arranged at the top of the crossbar 11, reinforcing diagonal bars 13 respectively arranged between the crossbar 11 and each vertical bar 12, and reinforcing crossbars 14 respectively arranged between the ends of the two vertical bars 12. A forklift mounting portion 15 is arranged on one side of each of the vertical bars 12, which is used to connect the crossbar assembly 10 to a forklift. A hydraulic cylinder interface is also arranged on one side of the vertical bar 12, so as to facilitate the transmission of hydraulic oil into the hydraulic drive assembly described below. It should be noted that a hydraulic pipe is arranged on one side of the crossbar 11, and the hydraulic pipe is connected to the hydraulic drive assembly 25 described below and the hydraulic cylinder interface, and the hydraulic pipe is not shown in the figure.

[0019] Each of the clamp bodies 20 includes a mounting block 21 disposed at one end of the cross bar 11, a positioning portion 22 disposed at one side of the mounting block 21, a rotating shaft 23 vertically passing through the positioning portion 22, a clamping block 24 fixedly sleeved on the outside of the rotating shaft 23, a hydraulic drive assembly 25 disposed on the mounting block 21 to drive the rotating shaft 23 to rotate, and a roller 26 disposed at the bottom of the mounting block 21 and with its outer edge abutting against the side of the folding box.

[0020] Ribs 27 are provided on the top of the mounting block 21 and around the positioning portion 22. The ribs 27 surround each other to form a mounting groove 28. The hydraulic drive assembly is installed in the mounting groove 28. The ribs 27 on the mounting block and the ribs 27 on the positioning portion are welded to each other, thereby increasing the connection strength between the mounting block 21 and the positioning portion 22.

[0021] A shaft seat 221 is disposed at the top of the positioning portion 22, and the rotating shaft 23 is rotatably inserted in the shaft seat 221. A swing arm 222 is mounted on the portion of the rotating shaft 23 that exceeds the top of the shaft seat 221, and the swing arm 222 is used to be rotatably connected to the hydraulic drive assembly 25, so that the hydraulic drive assembly 25 can drive the rotating shaft 23 to rotate after rotating, and then drive the clamping block 24 to rotate.

[0022] A conical guide portion 231 is disposed at the end of the rotating shaft 23 so as to guide the end of the rotating shaft 23 to be inserted into the pin hole.

[0023] The clamping block 24 includes a circular body 241 and a clamping portion 242 disposed on the circular body 241. The cross section of the pin hole is U-shaped, and the pin hole is opened on the plate and passes through the plate. The specific structure of the pin hole is well known to those skilled in the art, and is not the main content of the present invention, and will not be described here.

[0024] When in use, the forklift controls the forklift clamp to move from top to bottom, so that the clamping block 24 just passes through the pin hole, and then the hydraulic drive assembly 25 drives the rotating shaft 23 to rotate, so that the clamping part 242 of the clamping block 241 rotates and is misaligned with the pin hole, so that the folding box can be lifted after the forklift clamp is lifted. Only two pin holes on one side of the folding box need to be clamped to lift the entire folding box. Thus, the clamping of the folding box is realized. When the folding box needs to be put down, it is only necessary to place the folding box directly at the corresponding position, control the forklift clamp to move downward a short distance, so that the top of the clamping part 242 does not abut against the plate of the pin hole, and then drive the rotating shaft 23 to rotate, so that the clamping part 242 rotates until the clamping block 24 is aligned with the pin hole, and then the forklift clamp is controlled to move upward to separate the forklift clamp from the folding box.

[0025] Compared with the prior art, the forklift clamp for a folding box provided by the utility model increases the stability of the structure through the reinforcing diagonal rod 13 and the reinforcing cross rod 14, and sets the clamp body 20, which includes a rotating shaft 23, a clamping block 24 sleeved on the outside of the rotating shaft, and a hydraulic drive assembly 25 for driving the rotating shaft 23 to rotate, so that it can be clamped in conjunction with the pin hole on the folding box. Specifically, after the clamping block 24 passes through the pin hole, the rotating shaft 23 is controlled to rotate, so that the clamping block 24 is misaligned with the pin hole, and the folding box can be fixed on the top of the clamping block 24 by relying on the gravity of the folding box itself.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
