Problems solved by technology

However, the above-mentioned process of removing the third attachment frame 203 and the fourth attachment frame 204 relies on manual removal operations, which not only takes a long time to remove, consumes a large number of workers, but also has a relatively large potential safety hazard, which will cause the attachment of tower cranes in the construction process. The dismantling operation brings great difficulty

Abstract

The invention discloses an auxiliary device for disassembling a tower crane attachment bracket. The auxiliary device for disassembling the tower crane attachment bracket comprises a strip-type bracket, a front-end guide wheel, a middle guide wheel, a middle guide wheel adjusting shaft, an adjusting shaft support seat, a driving device and a steel wire rope, wherein the front-end guide wheel is arranged at the front part of the strip-type bracket; the middle guide wheel, the middle guide wheel adjusting shaft and the adjusting shaft support seat are arranged in the middle of the strip-type bracket; a wheel disc of the front-end guide wheel is vertically arranged; a wheel disc of the middle guide wheel is horizontally arranged in an initial installation state; a tangent line between the edge of the wheel disc of the middle guide wheel and the edge of the wheel disc of the front-end guide wheel is parallel to the extension direction of the strip-type bracket; one end of the steel wire rope is connected with the driving device; the other end of the steel wire rope sequentially penetrates through the middle guide wheel and the front-end guide wheel and is connected with an attachment bracket to be disassembled.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to an auxiliary device for removing an attachment frame of a tower crane. Background technique [0002] The tower crane is the main large-scale mechanical equipment on the construction site. It is responsible for the important task of vertical transportation. Attachment devices are set on the object (that is, the tower body of the tower crane and the building are connected by steel components) to meet the strength and stability requirements of the tower crane. [0003] see figure 1 , the tower crane attachment device 200 is generally symmetrically connected in a "eight" shape. When the tower crane 100 is dismantled, as the tower continues to descend, the tower crane attachment device 200 will also be removed sequentially from top to bottom. When the attachment device of the tower crane is removed, it needs to be lifted with the hook of the tower crane. Sinc...
