A Deviation Correction Method for Tower Crane

Abstract

The invention discloses a deviation rectifying method of a tower crane. The outer diameter of a connecting pin shaft is reduced by replacing a connecting pin shaft between a built-in supporting leg and the bottom of a tower body, deviation of the tower crane is rectified to the opposite side of the inclination direction by replacing the upper and lower gap difference between the connecting pin shaft and a connecting hole, and the connection of the built-in supporting leg and the bottom of the tower body after deviation rectifying is fixed by adopting subsequent stabilizing measures. Operationis easy and convenient, the deviation rectifying effect is obvious, construction operation can be carried out on the premise of not dismantling the tower crane, a large amount of material resources and manpower are saved, the safety risk is reduced, and meanwhile, the tower crane has a good stabilizing effect and is suitable for rectification operation of the tower crane.

Description

【Technical field】 [0001] The application belongs to the technical field of deviation correction of tower cranes, and in particular relates to a method for correcting deviation of a tower body of a tower crane. 【Background technique】 [0002] Tower crane (hereinafter referred to as "tower crane") is a kind of lifting equipment for horizontal and vertical transportation of materials, mainly used for lifting and installation of building materials and prefabricated components. It is widely used in the field of construction with the advantages of fast speed and wide working range, and plays an important role. [0003] However, the tower crane belongs to an eccentric unbalanced moment device erected in the sky, and the large and heavy superstructure produces a large overturning moment on the tower supporting its work (the tower cranes currently used in the world are based on the corresponding The maximum tipping moment of the model is limited to 400-15000KN.M), so the tower crane...

Problems solved by technology

[0007] In order to solve the technical problems of complex deviation correction steps, high deviation correction cost and poor deviation correction effect of existing tower cranes, this application provides a deviation correction method for tower cranes. The outer diameter of the connecting pin shaft is small, and the difference between the upper and lower gaps between the connecting pin shaft and the connecting hole is used to correct the deviation of the tower crane towards the opposite side of the inclination direction, and at the same time, follow-up stabilization measures are used to fix the pre-embedded outriggers and the bottom of the tower body after deviation correction The connection is not only easy to operate and low in cost, but also has a good stabilizing effect
