Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of large casting hoisting auxiliary equipment, and particularly relates to a pneumatic unhooking clamping device. BACKGROUND

[0002] In the casting production process, after the casting is formed and the mold is removed, it usually needs to be transported to the later polishing production line for further processing. However, when there is no conveying belt for direct conveying, the transportation of the casting often depends on manual operation of hoisting equipment.

[0003] The existing hoisting equipment usually adopts a hook type clamping device for fixation when hoisting heavy castings. Since the weight of the metal casting is large, in the hoisting process, the heavy object will have a large extrusion effect on the clamping device, causing the bottom of the clamping device to be difficult to separate smoothly from the bottom surface of the casting. In this case, the worker needs to exert a large force to complete the separation operation of the lifting appliance and the casting. This operation mode not only increases the labor intensity of the worker, but also makes the loading and unloading action of the worker difficult to control accurately, which is easy to cause safety accidents, thereby significantly increasing the unsafe factors in the transportation process of the casting.
