Description

Technical Field

[0002] A high-rise building steel corridor generally refers to two high-rise buildings connected by an overhead steel connector to meet the requirements of building shape and functional use. The connector is the steel corridor. During the construction of high-rise buildings, the steel corridor will be hoisted to a suitable height position through a hoisting device.

[0003] Chinese patent application No. 202122614205.7 discloses a hoisting device for a high-rise steel corridor, in which the bottom of the rope on the hoisting device is fixed on the steel corridor, and the rope passing through the guide pulley and the load-bearing pulley is driven by a winch to move and lift the steel corridor. However, the rope will contact the first pulley body on the load-bearing pulley and the second pulley body on the load-bearing pulley. When the rope is fixed to the steel corridor and then lifted by the winch, the rope will exert a large contact force on the second pulley body and the first pulley body. If granular impurities are attached to the outer surface of the rope, the granular impurities will cause wear on the parts of the second pulley body and the first pulley body that are in contact with the rope, thereby reducing the service life of the second pulley body and the first pulley body, thereby reducing the service life of the load-bearing pulley and the guide pulley, and increasing the cost of use. For this reason, we propose a hoisting device for a high-rise steel corridor. Utility Model Content
