Abstract

The invention discloses a climbing belt self-hoisting system of a large-sized movable-arm tower crane. The climbing belt self-hoisting system comprises a hoister, a tower body composed of a plurality of standard sections of the tower crane, a hoister base, a pulley block, a pin, a pulley block base, a clamp A, a clamp B and a clamp C, wherein the hoister base is vertically fixed at the middle of a column of the standard sections of the tower crane through the clamp C, the clamp B is fixed on an upper standard section of the tower crane, a hoist cable is arranged between and connected with the clamp B and a lifting lug of specially-produced channel steel No. 1, the pulley block base is fixed on the top standard section of the tower crane through the clamp A, two diagonal struts are fixed between a connection board of specially-produced channel steel No. 2 and the clamp B arranged on a lower standard section of the tower crane, and the pulley block is fixed on the pulley block base through the pin. The climbing belt self-hoisting system provided by the invention can realize self-hoisting of the climbing belt of the tower crane, does not occupy time of the tower crane, enables a construction period to be reduced, reduces cost for labor force and is repeatedly recyclable.

Description

technical field [0001] The invention relates to a self-elevating system of a climbing belt of a large-scale boom tower crane. Background technique [0002] In the field of construction, as buildings continue to rise, large boom tower cranes are used more and more frequently. As the main equipment for vertical transportation, the tower crane's operating capacity largely determines the speed of construction. However, due to the constraints of working surface factors, the number of tower cranes that can be installed is limited, and the efficiency of tower cranes is not very high. How to improve the efficiency of tower cranes in super high-rise construction has become one of the important research topics in the field of building construction today. Most of the large boom tower cranes adopt the internal climbing type, and the improvement of efficiency is mainly optimized from three aspects: one is to improve the lifting performance of the tower crane, the other is to shorten th...
