Description

Technical Field

[0001] The invention belongs to the technical field of hollow building block hoisting, and specifically refers to a hollow building block hoisting device for reserved space corner protection type buildings. Background Art

[0002] In construction, a large number of hollow blocks are required for some building walls. However, the existing hollow blocks still rely on manual loading and unloading by manpower during the loading and unloading process, which not only requires a large amount of manpower and material resources, but also has low handling efficiency, affecting work efficiency. It is easy to cause personal injury during the loading and unloading process, posing certain safety hazards. Secondly, the existing hollow blocks are clamped in an arc track oblique clamping manner during hoisting. This clamping manner is not parallel to the hollow blocks, which can easily damage the edges and corners of the hollow blocks and cause the hollow blocks to break. The subsequent use will seriously reduce the quality of the building, and not using it will cause a large amount of resource waste, and the applicability is poor. In addition, the hollow blocks have poor seismic performance. There is no shock absorbing device when hoisting the hollow blocks, which can easily cause the blocks to break during the hoisting process. Summary of the invention

[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides a hollow building block lifting device with reserved space and corner protection. In view of the fact that hollow blocks are easily broken during lifting, according to the hollow characteristics of the hollow blocks themselves, an inflatable air bag is inflated to squeeze the hollow inner wall, and the hollow blocks are lifted by static friction, thereby achieving the dual technical effects of neither damaging the lifting blocks themselves nor damaging the surrounding blocks. According to the traditional method of lifting hollow blocks, which easily damages the corners of the hollow blocks by clamping them with an arc track, a combination of pre-protection and parallel track clamping is adopted to achieve the technical effects of parallel clamping of the outer side of the hollow blocks, reserved space corner protection and soft shock-absorbing support at the bottom.

The setting of the reserved space type arc-shaped part can effectively prevent the edges and corners of the hollow building block from being damaged.
