Cantilever crane telescopic tower crane with attachment mechanism and working method thereof

Abstract

The invention discloses a cantilever crane telescopic tower crane with an attachment mechanism and a working method thereof, and belongs to the technical field of tower cranes of building machinery. The cantilever crane telescopic tower crane comprises a mounting base, a jacking hydraulic pump station, a climbing frame, a main arm, a main arm attachment mechanism, a cantilever crane main winch anda balance weight; the main arm attachment mechanism is used for assisting stabilization of the main arm through a building under construction; the cantilever crane is telescopic; an inhaul cable withone end connected with the telescopic cantilever crane is arranged on the telescopic cantilever crane; the other end of the inhaul cable is hinged to an inhaul cable winch arranged on the rear of thetelescopic cantilever crane through a main arm top bracket and provides pulling force; the inhaul cable tensions the telescopic cantilever crane, and stress borne by the telescopic cantilever crane is reduced. The cantilever crane telescopic tower crane can reduce the length of the cantilever crane and is suitable for operation in a narrow space. The main arm attachment mechanism achieves auxiliary supporting to the main arm, the main arm is prevented from overturning, the overturning moment of the main arm is reduced, the auxiliary mechanism and the main arm can move relatively in the vertical direction, the gravity of the main arm is prevented from acting on an attached object, and damage to an attached building is reduced.

Description

technical field [0001] The invention relates to a tower crane and a working method thereof, in particular to a telescopic boom tower crane with an attachment mechanism and a working method thereof suitable for building construction, and belongs to the technical field of construction machinery industry. Background technique [0002] Tower crane is an important equipment for the modern construction industry to realize production mechanization and automation, reduce physical labor intensity and improve production efficiency. With the massive increase of high-rise and ultra-high-rise buildings, independent height tower cranes can no longer fully meet the needs of large-height lifting work. When the height of the tower body is high, the bending moment of the tower body increases, and the overall stability of the tower crane decreases. Therefore, when the height of the tower crane generally exceeds the free height, the tower crane must use attached struts to attach the tower body ...

AI Technical Summary

Problems solved by technology

When the tower crane is limited by the construction site, the installation position is at the corner of the building, the attachment distance is far away, and the angle of the attachment strut is too small and other unfavorable conditions, the traditional anchoring method will make the attachment strut bear a lot of force, causing the attachment The cross-section of the strut design is too large and the length is too long

The existing attachment method completely limits the freedom of the main arm, the main arm cannot move up and down, and the force on the main arm and the attachment is relatively large
