Description

Technical Field

[0001] The utility model relates to the technical field of hoisting tools, in particular to a modular building hoisting device. Background Art

[0002] Modular construction refers to dividing a building into several spatial modules, manufacturing these modules and all the equipment, pipelines, decoration, fixed furniture in the modules separately in the factory, and also completing the facade decoration at the same time, and then transporting these modules to the construction site as components and assembling them together in a similar way to building blocks. Modular construction is a high-end product of building industrialization and has its own high degree of integrity.

[0003] For example, a modular building hoisting device with announcement number CN216764054U includes a hook and two upper top plates, a plurality of springs are fixedly arranged at the bottom of the upper top plates, the other end of the springs is fixedly connected to the lower bottom plate, a rotating block is arranged between the two upper top plates, a side plate is fixedly arranged at the top of the lower bottom plate, a hinge shaft is fixedly arranged at one end of the side plate away from the lower side plate, the two side plates are hinged through the hinge shaft, a steel rope is fixedly connected to the bottom of the hinge shaft, and the bottom of the steel rope is fixedly connected to the hook. When the hoisting device is hoisting building materials, when subjected to force, the springs directly on the upper top surface and the lower bottom surface will be compressed toward one side, and the corresponding side will be stretched to form an opposite elastic force, which reduces the force of the compressed springs and improves the buffering effect. The hoisting itself is subjected to less force, which reduces the risk of bending and deformation of the hoisting device due to long-term force. A triangular stable structure is formed between the two side plates and the lower side plate, which improves the stability of the device.

[0004] However, when this device is used to lift materials, most cranes are unable to clamp and fix the materials well, resulting in the materials easily falling off the crane during lifting. The falling of materials can easily cause safety accidents, making it impossible for the life safety of construction workers to be effectively protected while they are working. Utility Model Content
