Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a wind resistance device for a tower crane. Background Technique

[0002] A tower crane, also known as a tower hoist, is a rotating crane with a jib installed on the upper part of a tall tower body. It has a large working space and is mainly used for the vertical and horizontal transportation of materials and the installation of building components in building construction. It consists of three parts: a metal structure, a working mechanism, and an electrical system. The metal structure includes a tower body, a jib, and a base, etc. The working mechanism has four parts: hoisting, luffing, slewing, and traveling.

[0003] Chinese Patent Publication No. CN206827995U discloses a tower crane with an extended wind resistance sleeve. The technical solution provided by this patent document is as follows: It includes a crane body. A fixed frame is installed and built on one side of the crane body. A rotating base is installed at the upper end of the fixed frame. One end of the rotating base leads out a rotating jib. A moving trolley is provided on the rotating jib. An extended wind resistance sleeve is installed at the bottom end of the moving trolley. The extended wind resistance sleeve is composed of a fixed sleeve and a telescopic sleeve. A support rod is connected to the outer side end of the telescopic sleeve. The support rod is connected to a moving block. The moving block is installed on the inner frame body of the fixed frame and is arranged to slide vertically. By the above method, the utility model can improve the stability of the tower crane when hoisting items. The steel wire sling connected to the upper end of the hook device can be surrounded and protected by the extended wind resistance sleeve to prevent the steel wire sling from shaking.

[0004] In order to solve the problem that the traditional tower crane has insufficient protection for the hook device, the steel wire rope is prone to shaking and causing danger when hoisting items, and the traditional tower crane does not have a device for surrounding and protecting the steel wire sling. The prior art is to adopt the method that the steel wire sling connected to the upper end of the hook device can be surrounded and protected by the extended wind resistance sleeve to prevent the steel wire sling from shaking. However, there will still be a situation where the middle part of the tower crane cannot be protected against wind, which affects the construction efficiency, and further leads to the problem of reduced work efficiency.
