A hook is fixedly connected to the bottom of the lifting device body 1.
[0037] The working principle of the above technical solution is as follows:
[0038] During operation, insert the forklift truck into the middle of the spreader body 1. Shake the crank 13 to drive the turntable 12 to rotate. The turntable 12 drives the lead screw 11 to rotate. The lead screw 11 drives a pair of clamping blocks 14 to approach each other, so that the clamping blocks 14 contact the truck. The locking assembly fixes the clamping blocks 14 to the forklift forks. Fix the spreader body 1 to the forklift mast through the fixing assembly. Lift the goods with the hook at the bottom of the spreader body 1. Through the settings of the lead screw 11, turntable 12, crank 13 and clamping blocks 14, an adjustable spreader is formed, realizing the adaptation of the spreader to forklift forks of different sizes, solving the problems of sliding or non - adaptation when forklift forks of different sizes are installed and matched with a general spreader, improving the adaptability of the spreader during use, and reducing the shaking of the spreader when lifting goods due to non - adaptation.
[0039] Please refer to Figure 1 、 Figure 3 and Figure 4 The locking assembly includes a push rod 2, a limit block 21, a rotating handle 22 and reverse teeth 23. The push rod 2 is threadedly connected to the bottom of the clamping block 14. The limit block 21 is rotatably connected to the end of the push rod 2 close to the clamping block 14. The limit block 21 is wedge - shaped. The reverse teeth 23 are fixedly connected to the end of the limit block 21 away from the push rod 2. Multiple groups of reverse teeth 23 are arranged at the end of the limit block 21 and are evenly distributed at the end of the limit block 21. The rotating handle 22 is slidably connected to the side wall of the push rod 2 away from the limit block 21.
[0040] During operation, the forklift fork is inserted into the middle of the spreader body 1 from the thinner part of the limit block 21. After the spreader body 1 moves to the appropriate position of the forklift fork, rotate the rotating handle 22 to drive the push rod 2 to rotate. The push rod 2 drives the limit block 21 and the reverse teeth 23 to move towards the top of the clamping block 14. The forklift fork is arranged with a thin front end and a thick rear end, which cooperates with the limit block 21. The reverse teeth 23 contact and lock the bottom of the forklift fork. Pull the rotating handle 22 to change the torque when rotating the rotating handle 22. Through the settings of the push rod 2, limit block 21, rotating handle 22 and reverse teeth 23, a structure for locking the forklift fork is formed, realizing the function of fixing the forklift fork inserted into the spreader body 1, solving the problem of relative sliding between the spreader body 1 and the forklift fork when they cooperate, improving the stability during goods lifting, and increasing the convenience when tightening the limit block 21.

[0044] During operation, after the forklift forks are inserted into the middle of the sling body 1, the roller 4 contacts the top of the forklift forks. When it is necessary to adjust the position of the sling body 1 on the forklift forks, the sling body 1 is pushed to move on the forklift forks. The roller 4 changes the static friction between the sling body 1 and the forklift forks into rolling friction. Through the setting of the roller 4, this step realizes the function of changing the static friction between the sling body 1 and the forklift forks into rolling friction, solves the problem of large frictional damage when the sling body 1 moves on the forklift forks, improves the convenience of moving the sling body 1 on the forklift forks, and increases the service life of the components.

Through the setting of the sealing plate 5, this step seals the top of the sling body 1, reducing the entry of dust or foreign objects into the interior of the sling body 1, thereby causing abnormal wear of the lead screw 11 and the clamping block 14, and increasing the service life of the components.
[0047] Please refer to Figure 3 As shown, a rubber pad 6 is fixedly connected to the inner side wall of the clamping block 14 away from the limit block 21. The rubber pad 6 is made of rubber.
[0048] During operation, when the clamping block 14 clamps the freight car, the rubber pad 6 contacts the side surface of the forklift forks. Through the setting of the rubber pad 6, the rubber pad 6 contacts the side surface of the forklift forks, increasing the contact area between the clamping block 14 and the forklift forks and playing a buffering role.
[0049] Please refer to Figure 3 As shown, the limit block 21 is made of metal.
[0050] During operation, the limiting block 21 is made of metal, which increases the structural strength of the general lifting tool and improves the ability to lift goods.
[0051] During operation, insert the forklift's fork into the middle of the lifting tool body 1, shake the crank 13 to drive the turntable 12 to rotate, the turntable 12 drives the lead screw 11 to rotate, the lead screw 11 drives a pair of clamping blocks 14 to approach each other, so that the clamping blocks 14 contact the fork, and the locking component fixes the clamping blocks 14 to the fork. Fix the lifting tool body 1 to the forklift mast through the fixing component, and lift the goods through the hook at the bottom of the lifting tool body 1. The fork is inserted into the middle of the lifting tool body 1 from the thinner part of the limiting block 21. After the lifting tool body 1 moves to the appropriate position of the fork, rotate the rotating handle 22 to drive the ejector rod 2 to rotate, and the ejector rod 2 drives the limiting block 21 and the reverse teeth 23 to move towards the top of the clamping block 14. The fork is arranged with a thin front end and a thick rear end, which cooperates with the limiting block 21. The reverse teeth 23 contact the bottom of the fork and lock the fork. Pull the rotating handle 22 to change the torque when rotating the rotating handle 22. After the lifting tool body 1 is inserted into the fork, pull the telescopic rod 3 to the appropriate position and lock it. Slide the fixed clamp 31, clamp the fixed clamp 31 on the mast and tighten the fixing screw 32 for fixation. After the fork is inserted into the middle of the lifting tool body 1, the roller 4 contacts the top of the fork. When it is necessary to adjust the position of the lifting tool body 1 on the fork, push the lifting tool body 1 to move on the fork, and the roller 4 changes the static friction between the lifting tool body 1 and the fork into rolling friction. The sealing plate 5 seals the top of the lifting tool body 1 to reduce dust or foreign objects from entering the inside of the lifting tool body 1. When the clamping block 14 clamps the fork, the rubber pad 6 contacts the side of the fork. The limiting block 21 is made of metal, which increases the structural strength of the general lifting tool and improves the ability to lift goods.
[0052] The above embodiments only represent the specific implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention.
