Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hoisting fixtures, in particular to a hoisting fixture for semi-trailer production. Background Art
[0002] Semi-trailers are large in size and weight, so the main load-bearing beam and the secondary load-bearing beam in the chassis structure of the semi-trailer are long and heavy. During the production process, it is often necessary to use lifting equipment to lift and install them. The traditional lifting method generally uses a hook to lift. However, since the raw materials of the semi-trailer are of different lengths, especially the main load-bearing beam and the secondary load-bearing beam are different in length, during the lifting process, it is often necessary to replace different types of clamps, which affects the convenience of semi-trailer production and lifting.
[0003] In order to solve the above problems, we propose a lifting fixture for semi-trailer production to solve the above problems. Utility Model Content

The top of the clamping plate is slidably installed on the inner middle part of the channel steel. Cylinders are fixedly installed on the lower sides of both ends of the channel steel. The output end of the cylinder is fixedly connected to the back of the clamping plate. The two groups of clamping plates are driven by the cylinder so that they can slide horizontally. When the two groups of clamping plates slide toward the center point, the raw material objects to be hoisted can be clamped at both ends.

[0024] The embodiment of the present application provides a hoisting fixture for semi-trailer production, and its main technical solution is that the connecting column 5 slides horizontally in the limiting slide groove 3, and then the clamp tooling is limited and fixed by the fixing nut 7, so that the staff can adjust the positions of the two sets of clamp tooling at any level according to the needs, so that the utility model can clamp and hoist semi-trailer materials of different lengths, thereby improving the extensiveness and convenience of the utility model in practical applications;
[0025] At the same time, by providing a fixing hook 13 on one side of the bottom end of the clamping plate 12, it is convenient for the staff to wrap the binding rope to bind and fix the semi-trailer materials to be hoisted, further improving the safety and stability when hoisting the production raw materials.
[0026] Example: Refer to Figure 1-5 As shown, a lifting fixture for semi-trailer production in this embodiment includes a lifting beam 1, and clamping tools are arranged on both sides of the bottom end of the lifting beam 1. The raw materials for semi-trailer production can be clamped and lifted at both ends through two sets of clamping tools.
[0027] The fixture tooling includes a channel steel 4, and "L"-shaped clamping plates 12 are arranged on both sides of the bottom end of the channel steel 4. The top of the clamping plate 12 is slidably installed on the inner middle part of the channel steel 4. Cylinders 9 are fixedly installed on the lower sides of both ends of the channel steel 4, and the output end of the cylinder 9 is fixedly connected to the back of the clamping plate 12.
[0028] Among them, the cylinder 9 is used to push the clamping plate 12 to slide horizontally. When the two groups of clamping plates 12 slide toward the center point, the production raw materials placed in the middle of the bottom end of the channel steel 4 can be clamped at both ends.
[0029] At the same time, by providing a fixing hook 13 on one side of the bottom end of the clamping plate 12, it is convenient for the staff to tie the production materials clamped by the two groups of clamping plates 12 with ropes, further improving the safety and stability of the production raw materials when hoisting.
[0030] A connecting column 5 is provided in the middle of the top end of the channel steel 4, and a limiting block 6 is provided on the top of the connecting column 5. The limiting block 6 is slidably installed in the middle of the inner side of the suspension beam 1. An external thread is provided in the middle of the upper end of the connecting column 5, and a fixing nut 7 is movably installed at the external thread. By moving the connecting column 5, the position of the channel steel 4 can be horizontally moved, and then by twisting the fixing nut 7, the position of the connecting column 5 can be limited and fixed.
[0031] A limiting slot 3 is provided at the inner bottom of the suspension beam 1, and the top of the connecting column 5 passes through the limiting slot 3 and slides horizontally in the limiting slot 3. The limiting block 6 is slidably installed in the inner middle part of the limiting slot 3. The limiting slot 3 limits the limiting block 6 to prevent the limiting block 6 from falling from the inner bottom of the suspension beam 1 when sliding horizontally. When the limiting block 6 moves to a suitable position, the fixing nut 7 is twisted to make the fixing nut 7 come into close contact with the bottom of the limiting slot 3, thereby clamping and fixing the limiting block 6, so that the position of the clamp tooling is limited and fixed.
[0032] A mounting groove 10 is provided at the inner bottom of the channel steel 4, and the clamping plate 12 slides horizontally in the inner middle part of the mounting groove 10. In addition, a sliding rod 11 is provided at the inner upper end of the mounting groove 10, and the top of the clamping plate 12 is slidably connected to the sliding rod 11. The sliding rod 11 can limit the horizontal sliding of the clamping plate 12, thereby improving the stability of the clamping plate 12 during horizontal displacement.
[0033] In some examples, a lifting ring 2 is provided in the middle of the upper end of the hanging beam 1 , and the lifting ring 2 is connected and fixed to the hanging beam 1 by a plurality of sets of fixing bolts, so that the lifting ring 2 can lift and pull the hanging beam 1 .
[0034] In some examples, reinforcing ribs 8 are provided between the connecting column 5 and the channel steel 4 , so as to improve the strength and stability of the connection between the channel steel 4 and the connecting column 5 .
[0035] The working principle of the utility model is:
[0036] When it is necessary to hoist the raw materials and objects for semi-trailer production, first adjust the positions of the two sets of fixtures according to the length of the raw materials;
[0037] The specific steps are as follows: first, loosen the fixing nut 7 to release the limit of the connecting column 5, then move the connecting column 5 so that the fixture slides horizontally in the middle of the bottom end of the hanging beam 1, and when the distance between the two sets of fixtures is adjusted, twist the fixing nut 7 so that the fixing nut 7 is in close contact with the bottom of the limiting slide groove 3, thereby locking and limiting the position of the fixture;
[0038] Then, the clamping plates 12 are pushed by the cylinder 9, so that the two sets of clamping plates 12 move toward the center point, thereby clamping the raw materials at both ends;
[0039] At the same time, by providing a fixing hook 13 on one side of the bottom end of the clamping plate 12, it is convenient for the staff to wrap the binding rope to bind and fix the raw materials, further improving the safety and stability of the production raw materials when hoisting;
[0040] After the raw materials are tied and fixed, the lifting beam 1 is lifted and pulled through the lifting ring 2, so as to realize the lifting work of the raw materials on the semi-trailer.
