This equipment has a high carrying capacity and flexibility, can operate in a small space, and can easily move and stack containers.

[0003] When loading and unloading double-layer ton bags, the existing forks have limited operating space for forklifts, which increases the difficulty of loading and unloading operations. In addition, the shape and hardness of traditional forks limit their adaptability to ton bags, resulting in frequent punctures of ton bags by the forks during the forking and placement process. This not only causes cargo loss, but also may cause safety hazards and seriously affect operational efficiency. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1:

[0026] See also Figure 1-Figure 4 As shown, a fork suitable for transporting and loading and unloading ton bags, comprising:

[0027] Plug-in board 1;

[0028] The hook mechanism 2 is buckled on the outside of the plug-in board 1. The hook mechanism 2 includes a hook plate 201, an upper hook 202 and a lower hook 203. The hook plate 201 is connected to the outside of the plug-in board 1. The top end of the hook plate 201 is fixedly connected to the upper hook 202, and the bottom end of the hook plate 201 is fixedly connected to the lower hook 203;

[0029] The snap-fitting plate 3 is inserted into the outside of the hook mechanism 2. The upper hook 202 and the lower hook 203 are welded to the upper and lower ends of the hook plate 201. The upper hook 202 and the lower hook 203 are respectively snapped onto the outside of the insertion plate 1 and the snap-fitting plate 3. A fork mechanism 4 is fixedly connected to the outside of one side of the hook mechanism 2. A limiting mechanism 5 is provided on the outside of the hook mechanism 2. A plurality of holes and slots are horizontally opened on the outside of the insertion plate 1.

[0030] Specifically, by engaging the upper hook 202 and the lower hook 203 on the insertion plate 1 and the locking plate 3 , the hook plate 201 can pass through the limiting mechanism 5 and be installed on the forklift.

[0031] From the above, it can be seen that after the hook plate 201 is clamped and fixed on the outside of the insertion plate 1, the two triangular brackets 401 can be installed, and the fork rod 402 is designed to be circular, which can prevent the square fork from cutting the lifting belt during loading and unloading. The triangular bracket 401 is designed to be a triangle, which makes full use of the mechanical principles and increases stability.

[0032] Example 2:

[0033] refer to Figure 3 and Figure 4 As shown, the fork mechanism 4 includes a triangular bracket 401, a fork rod 402 and a head 403. The triangular bracket 401 is welded to the outside of one side of the hook mechanism 2. The top of the triangular bracket 401 is welded with a fork rod 402. The head 403 is installed on the outside of one side of the fork rod 402. There are two triangular brackets 401 horizontally, and the tops of the two triangular brackets 401 are both welded with a fork rod 402. The fork rod 402 is a cylindrical structure. The limiting mechanism 5 includes a positioning pin 501, an insertion rod 502 and The insertion pin 503 and the positioning pin 501 are arranged at the top end of the upper hook 202. The bottom end of the positioning pin 501 is fixedly connected to the insertion rod 502. The bottom end of the insertion rod 502 is fixedly connected to the insertion pin 503. The outer sleeve of the insertion rod 502 is provided with a tension spring 504. The insertion rod 502 passes through and is inserted into the interior of the upper hook 202. The top end of the tension spring 504 is abutted against the bottom end of the upper hook 202. The insertion rod 502 is elastically and telescopically connected to the tension spring 504. The insertion pin 503 is inserted in the hole groove of the insertion plate 1.

[0034] Specifically, when the positioning pin 501 is stretched, the elastic expansion and contraction between the insertion rod 502 and the tension spring 504 can enable the insertion pin 503 to be inserted and fixed in the snap-fit ​​groove outside the insertion plate 1, thereby fixing the hook plate 201 on the outside of the insertion plate 1 and the snap-fit ​​plate 3.

[0035] From the above, it can be seen that when the hook plate 201 is being installed, the positioning pin 501 is stretched, so that the elastic expansion and contraction between the insertion rod 502 and the tension spring 504 can lift the insertion pin 503, so that the insertion pin 503 is limitedly inserted inside the card slot of the insertion plate 1, thereby facilitating the installation and disassembly of the fork mechanism 4, and by inserting it inside the card slot, the fork can be prevented from moving left and right during operation.
