Movable arm type tower crane supporting system auxiliary circulating lifting transport device and construction method thereof

Abstract

A movable arm type tower crane supporting system auxiliary circulating lifting transport device comprises a movable arm type tower crane and further comprises a set of supporting fixing piece, the supporting fixing piece is connected to the two sides of the top of a standard knot and connected with a rotary table base; the bottom surface of the supporting fixing piece is vertically connected witha lifting lug, the lifting lug is connected with lifting chains, and the lower ends of the lifting chains are connected with supporting frames; the at least three supporting frames are distributed onthe standard knot at intervals and all provided with C-shaped frame bases in advance. According to a construction method, through the rotary table of the movable arm type tower crane and the supporting fixing piece arranged at the top of the standard knot, installing of fulcrums during circulating lifting transport is omitted; and the supporting frames and the C-shaped frame bases are divided intotwo parts, a middle supporting frame temporary hanging method is adopted, the problems that components are damaged or the lifting space is insufficient due to the fact that the supporting frame and the C-shaped frame bases are directly lifted can be solved, a main beam, a connection rod, a vertical inclined support, a horizontal support and other parts are detachable and are in a partial rotationconnecting mode and are convenient to disassemble, folding and assembling during lifting, and the lifting space is saved.

Description

technical field [0001] The invention belongs to the construction field of tower crane equipment, and in particular relates to a support and reversing device and a construction method of a boom-type tower crane. Background technique [0002] In the construction of high-rise or ultra-high-rise buildings, tower cranes are important equipment for transporting materials during the construction process. However, due to the increasingly dense buildings and limited construction sites, traditional flat-arm tower cranes are prone to disputes over territory and airspace. The height is limited, so the boom-type self-climbing tower crane is often used to meet the construction requirements of different heights, and the boom-type tower crane is limited by the length of the standard joint. If there is a higher working height, it needs to be lifted and lifted as a whole. [0003] The previous hoisting method was to rely on another boom tower for auxiliary hoisting. Since it was necessary to ...

AI Technical Summary

Problems solved by technology

[0003] The previous hoisting method was to rely on another boom tower for auxiliary hoisting. Since it was necessary to adjust the verticality of the tower body to calibrate the splicing position of the supporting main beam, this tower could not work. At this time, the two boom towers could not normally take charge of the site The vertical transportation will greatly affect the construction work on site; there is also a vertical overall reverse hoisting through the standard under-section support system, but there will be damage or suspension of the main frame and support rods in the support system due to the overall hoisting. In the case of insufficient transportation space, the lifting fulcrum of this method is located on the support system, which is not easy to construct and operate, and due to the existence of the upper support system, it is often not conducive to the overall vertical lifting of the lower support system during lifting.
