Cable loading crane with automatic decimal alignment pressure-bearing and shearing resistance functions

Abstract

The invention relates to a cable loading crane with automatic decimal alignment pressure bearing and shearing resistance functions, comprising a sling connected with an end beam, wherein a heavy member is fixed at the lower end of the sling, a cable clip is arranged at the lower side of each of the two ends of the end beam, multiple pressure-bearing and shearing resistance blocks are also arrangedat the lower end of the end beam, the pressure-bearing and shearing resistance block comprises a top plate, a bottom plate is fixed at the lower end of the top plate, inverted hooks are arranged at four corners parts of the upper end face of the top plate, a hinge pin is also fixed on the upper end face of the top plate, an end beam bottom plate is arranged on the bottom end face of the end beam,and multiple rows of hinge pin holes corresponding to the hinge pins are formed in the end beam bottom plate. The cable loading crane is used for solving the problems in a conventional bolt fixing manner of the pressure-bearing and shearing resistance blocks and the end beam that bolt hole clearance is small, positioning is difficult, and the bolt needs to be tightened for multiple times, and hasthe characteristics of being simple and convenient to operate, and increasing the working efficiency.

Description

Technical field [0001] The invention relates to a cable-mounted crane with automatic alignment, pressure-bearing and shear-resistant. Background technique [0002] The cable crane is a kind of special equipment for the construction of suspension bridges. Its working method is to lift and install the steel beams under the bridge across the two main cables of the suspension bridge. At present, the cable crane has been widely used in The suspension bridge is under construction. As my country's cable crane design and construction technology become more and more mature, under the premise of meeting the feasibility and reliability of construction, the construction party has higher and higher requirements for the convenience of cable crane operation. [0003] Cable cranes generally have a pressure-bearing anti-shear system. The pressure-bearing anti-shear block is installed under the end beam. Before the cable-borne crane is hoisted, the pressure-bearing anti-shear block must be pressed ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a cable-loaded crane with automatic alignment, pressure and shear resistance, which solves the problem of difficult positioning and installation when switching positions of the pressure and shear resistance blocks of traditional cranes, and has the advantages of easy operation and reliable force transmission. , High work efficiency
