Description

Technical Field

[0001] The utility model relates to a hoisting device, specifically to a hoisting device for prefabricated building wall panels. Background Art

[0002] Reinforced concrete slab-shaped components for building assembly are processed and manufactured in prefabrication factories (yards) or construction sites, simply referred to as wall panels or wall slabs. Using precast concrete wall panels to build prefabricated large-panel buildings can improve the degree of factory and mechanized construction, reduce on-site wet operations, save on-site labor, overcome seasonal impacts, and shorten the building construction period.

[0003] During the assembly and transportation of building wall panels, hoisting equipment is usually required to hoist the building wall panels. There are many types of hoisting equipment for building wall panels on the market at present. For example, a wall panel horizontal hoisting clamp disclosed in Chinese Patent CN103395689A clamps the wall panel through a clamping arm, and adjusts the opening or clamping of the clamping arm by the lifting of a hoisting rod. During the lifting process, due to the weight of the wall panel pulling downwards, the relative position of the hoisting rod moves upwards, causing the clamping arm to clamp the wall panel. When putting down the wall panel, the lower part of the wall panel is supported, the steel wire rope becomes slack, and under the action of its own weight, the relative position of the hoisting rod moves downwards, and the clamping arm opens to release the wall panel. However, during the wall panel assembly process, it is often necessary to first lift the wall panel to a certain height and move it to a suitable position, and then with the assistance of workers, insert the lower end of the wall panel into the steel bar components fixed on the ground. During this process, the wall panel will stop and swing repeatedly, the hoisting rod cannot be stably stressed, and the clamping arm cannot stably clamp. Therefore, the hoisting mechanism disclosed in Chinese Patent CN103395689A is more suitable for simply lifting and laying flat the wall panel, and is not suitable for the wall panel assembly process.
