Description

Technical Field

[0001] The utility model relates to the technical field of hanging frames, in particular to an adjustable hanging frame for a loading and unloading vehicle skid. Background Art

[0002] The lifting frame for loading and unloading car skids is a kind of lifting equipment with strong practicality, stable performance, safety and reliability, and has a wide range of application prospects in various loading and unloading car plates and logistics distribution. Publication No. CN 215439381 U discloses a lifting frame for loading and unloading car skids. In the utility model, a staff member grasps a rectangular plate with one hand and rotates a worm with the other hand to rotate the worm wheel, driving the clamping block to move to both sides, placing the car skid partly between the two notches, and then rotates the worm in the opposite direction to make the clamping block move inward for clamping.

[0003] The above-mentioned prior art drives the worm wheel to rotate by rotating the worm, and then drives the clamping block to rotate, so that the clamping block clamps the car skid and then lifts it. The above-mentioned prior art mainly has the following problems: first, when adjusting the rotation of the clamping block, the operator is required to rotate the worm so that the worm drives the worm wheel to rotate. This process requires continuous and multiple rotations of the worm, that is, the rotation speed of the clamping block is slow, so that the clamping block clamps or releases the car skid at a slow speed, resulting in low lifting efficiency. In addition, the distance between the diameters of the two sets of clamping components cannot be adjusted, resulting in lifting only a car skid of a certain size, and poor applicability.
