Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hoisting equipment, in particular to a hoisting equipment for copper plate stacking. BACKGROUND

[0002] At present, for the transfer of plate materials, the clamps widely used in the industry are mainly divided into two categories: one is a claw clamp, which contacts the surface of the plate material through a claw, and uses the friction between the contact surfaces to achieve clamping and transfer of the material. However, this transfer method relying on friction has obvious defects: when the surface of the material is smooth, has oil stains or has high humidity, the friction will decrease significantly, which will easily cause the plate to slip during transfer, causing material damage and even safety accidents; at the same time, in order to ensure sufficient friction, the claw often needs to exert a large clamping force on the material, which is easy to cause deformation, surface scratches and other problems for some soft materials (such as plastic plates, thin wood plates) or surface-damaged materials (such as copper plates, steel plates), affecting the subsequent use of the material.

[0003] Another commonly used transfer method is magnetic transfer, which uses magnetic force to adsorb iron-containing or other magnetic materials to achieve transfer. However, the application of this method has strict material restrictions and is only suitable for materials with magnetism. It is completely unsuitable for non-magnetic materials such as aluminum alloy plates, plastic plates, glass plates and wooden plates, which greatly limits its application in diversified material transfer scenarios. In addition, magnetic transfer usually cannot achieve the stacking and transfer of multiple plates, because the magnetic force will decrease sharply with the increase in the number of plates, and the magnetic interference between adjacent plates may cause the stacking state to be unstable, often requiring individual transfer, which is low in efficiency. SUMMARY

[0004] In order to solve the above problems, the present application provides a hoisting equipment for copper plate stacking, which can drive the clamping jaw to turn inward and then lift the plate from below by using the adjusting module. Compared with the conventional claw that uses friction to transfer, the stability and safety of the hoisting equipment for copper plate stacking are higher when transferring plate materials, and the wear on the edge of the plate can be reduced. Compared with the magnetic transfer equipment, the hoisting equipment for copper plate stacking has no restrictions on the material of the plate, and can simultaneously transfer multiple plates, which is higher in transfer efficiency.
