Description

Technical Field

[0001] The invention relates to the technical field of construction machinery safety, and in particular to a climbing assistance protection device. Background Art

[0002] Tower crane is also called tower crane, which originated in Western Europe. It is a rotating crane with a boom mounted on the top of a tall tower. It has a large working space and is mainly used for vertical and horizontal transportation of materials and installation of building components in house construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower body, boom and base. The working mechanism has four parts: lifting, luffing, rotation and walking. The electrical system includes motors, controllers, distribution cabinets, connecting lines, signals and lighting devices, etc. In order to facilitate operators to go up and down, traditional tower cranes will set vertical ladders on the inside of the tower.

[0003] Traditional vertical ladders usually have guard rings or nets on the sides for safety protection. Due to the high height of the crane, when the workers slide sideways while climbing, they need to grab the guard rings or nets set on the outside to stop falling. However, the guard rings are generally rigid. When the workers fall, the rigid guard rings will cause the workers to bump into them. In severe cases, the workers may bump into their heads or vulnerable parts, causing secondary injuries to the falling people. Moreover, after the collision, the human body will become slow in movement due to pain and cannot firmly hold the guard rings on the sides. Therefore, it is very necessary to design a reasonable climbing assistance protection device. Summary of the invention
