[0002] In the process of modern manufacturing, the lifting and handling of goods is an important part of improving production efficiency. At present, there are two ways to lift the frame on the trailer production line: one is to directly lift it with chains, and the other is to lift it with clamps. However, the chain bundling method is very cumbersome whether it is tied or disassembled. Frequent dragging and transferring of chains is time-consuming and labor-intensive, with low work efficiency, and it is not easy to judge the state of the chain itself, and there is a safety hazard of chain breakage; while the clamp-type sling surrounds and clamps the frame from the outside, and uses the sling's clamp to clamp the wing surface of the frame longitudinal beam for lifting. The center of gravity needs to be adjusted repeatedly, which is inefficient.
[0003] Therefore, it is necessary to provide a frame hanger that is easy to use, safe, and highly adaptable to different operating scenarios. Utility Model Content

[0005] In order to achieve the above purpose, the specific technical solution of the utility model is as follows:
[0006] A lifting device for transporting a trailer frame comprises a lifting eye beam, a shoulder pole cross beam, a lifting hook and an opening and closing mechanism, wherein the lifting eye beam is fixed to the shoulder pole cross beam, the upper end of the lifting hook is hinged to the shoulder pole cross beam, and the lower end is hook-shaped for hanging goods, the lifting hooks are arranged in pairs and symmetrically distributed on the left and right sides of the shoulder pole cross beam, and the opening and closing mechanism is a telescopic mechanism, the two ends of the opening and closing mechanism are respectively hinged to the middle parts of the paired lifting hooks, and one end has the freedom to slide relative to the lifting hook.
[0007] The opening and closing mechanism includes a pressure handle and an articulated button. The articulated button includes an articulated button A and an articulated button B respectively fixed at the middle of the sides of the two hooks. One end of the pressure handle is hinged to the articulated button A, and a sliding groove is provided on the other end. The articulated button B passes through the sliding groove and is fixed to the hook and has the freedom to slide relative to the sliding groove. The pressure handle with one end of the sliding groove is extended out of the hook and is provided with a handle.
[0008] The number of the hooks is two or more pairs, which are evenly distributed along the extension direction of the shoulder pole crossbeam, and each pair of the hooks is provided with a set of opening and closing mechanisms.
[0009] The eye beam and the shoulder pole cross beam are welded and fixed.
[0010] The hinge button A and the hinge button B are respectively welded on the side surfaces of the hook.
[0011] A connecting plate is welded on the shoulder pole cross beam, and the upper end of the hook is hinged to the connecting plate through bolts.
[0012] The beneficial effects of the utility model are as follows: the utility model provides a sling for transporting a trailer frame, and by arranging a shoulder pole crossbeam, a hook and a pressure handle, the sling is configured as a wing-shaped structure, so that the lifting or disassembly thereof can be conveniently and quickly controlled, and the technical solution provided by the utility model has a simple structure, and the steps for performing a safety inspection on the sling are simple and convenient; in addition, when it is necessary to lift frames of different models, it is only necessary to control the pressure handle to be pressed down or lifted until the hook grasps the frame, and repeated adjustment is not required, so the utility model has good adaptability and high efficiency.

[0016] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.
[0017] like Figure 1 , Figure 2As shown, the utility model provides a lifting device for transporting a trailer frame, which includes a lifting ring beam 1, a shoulder pole beam 2, a hook 3 and an opening and closing mechanism, wherein the lifting ring beam 1 is welded and fixed on the shoulder pole beam 2 and is used to connect a lifting device, connecting plates are respectively provided at both ends of the shoulder pole beam 2, the hooks 3 are arranged in pairs, and the number is two pairs, and each pair of hooks 3 is stacked and distributed on the left and right sides of the shoulder pole beam 2, the upper ends of the two pairs of hooks 3 are respectively hinged to the connecting plates at both ends of the shoulder pole beam 2, and the lower ends are hook-shaped for hanging goods, and the two pairs of hooks 3 work together to ensure the stability of the frame 8 during the lifting process, and the opening and closing mechanism is a telescopic mechanism, which includes The present invention comprises a rod-shaped pressure handle 5 with a slide groove, and a hinge button set in the middle of the side of the hook 3, which are respectively a hinge button A6 and a hinge button B7, wherein one end of the pressure handle 5 is hinged to the hinge button A6, and the other end is provided with a slide groove, and the hinge button B7 passes through the slide groove and is fixed to the hook 3, and has the freedom to slide relative to the slide groove, and the distance between the hinge button A6 and the hinge button B7 is controlled by the relative sliding between the slide groove and the hinge button B7, the structure is simple, and the use is convenient, in addition, in order to facilitate the staff to control the lifting or falling of the pressure handle 5 and the opening and closing of the hook 3, one end of the pressure handle 5 with the slide groove is extended out of the hook and set to a handle shape. It should be noted that the lifting ring and the hook 3 in this embodiment are made of steel plates, which are strong and durable, and daily maintenance only needs to check the bolts 4 and the hinge button, which is simple and convenient.
[0018] When it is necessary to clamp the frame 8, the lifting device drives the eye beam 1 to move above the frame 8 and then drops it. The staff presses down the pressure handle 5 by hand to drive the two hooks 3 to open relatively. After opening them to clamp the frame 8, the staff lifts the pressure handle 5 to drive the two hooks 3 to close relatively, so that the hooks 3 grasp the frame 8. The lifting device can lift the eye beam 1 and thus lift the frame 8 and transfer it to the designated position. The structure is simple and the operation is convenient, which effectively improves the lifting efficiency and safety.
