Steel structure building truss hoisting and conveying system and machining process

Abstract

The invention provides a steel structure building truss hoisting and conveying system and a machining process. The system comprises a hoisting bottom plate, winding mechanisms, a guide mechanism, a bearing mechanism and horizontal adjusting mechanisms, wherein the winding mechanisms are symmetrically arranged at the lower end of the hoisting bottom plate, the guide mechanism is arranged at the lower end of the hoisting bottom plate and positioned between the winding mechanisms, the horizontal adjusting mechanisms are symmetrically arranged at the lower end of the guide mechanism, the bearing mechanism is arranged on the guide mechanism, and the bearing mechanism is positioned between the horizontal adjusting mechanisms. According to the steel structure building truss hoisting and conveyingsystem, the adjustable multi-station structure design concept is adopted to carry out hoisting and conveying on a steel structure truss, a mechanical integrated working structure is adopted, therefore, the labor intensity of workers is reduced, and the working flow is simplified; and meanwhile the structure with a scale is arranged, the whole adjusting process is visualized, and the accuracy of adjusting the left height position and the right height position when the steel structure building truss is hoisted and conveyed is improved.

Description

technical field [0001] The invention relates to the technical field of steel structure truss hoisting and transportation, in particular to a steel structure building truss hoisting and transportation system and a processing technology. Background technique [0002] Steel truss refers to a truss made of steel. In the fields of crane beams, bridges and hydraulic gates of industrial and civil buildings, steel trusses are commonly used as the main load-bearing components. Compared with the solid web beam, the steel truss uses sparse web members instead of the overall web plate, and the members mainly bear the axial force, which can often save steel and reduce the self-weight of the structure. This makes steel trusses particularly suitable for structures with large spans or heights. In addition, the steel truss is also convenient to make various shapes according to different usage requirements.

AI Technical Summary

Problems solved by technology

[0003] Since the amount of steel used in the web is less than that of the web of the solid web, the steel truss can often be made to have a larger height and thus have greater rigidity. However, the steel truss has more members and nodes, and the structure is more complicated. Manufacturing is labor-intensive, and the requirements for installation and construction equipment are relatively high. However, the following problems exist in the traditional steel structure building truss lifting and transportation operations. 1. The traditional steel structure building truss lifting and transportation operations are generally Manually use the lifting platform to rise to the position to be installed, and then use the hoisting tool to lift the steel structure truss to the corresponding height, manually adjust the height position of the left and right ends, and fix it with clamps. Usually, the size of the steel structure truss is large. Manual calibration and alignment is difficult, and high-altitude operations are likely to cause safety accidents

2. The traditional hoisting and conveying machinery cannot limit the load-bearing rope during the hoisting and conveying process to prevent violent shaking, and cannot automatically adjust the height of the corresponding left and right positions of the steel structure truss according to the difference in the left and right installation heights , and cannot automatically release the clamping and positioning state of the steel structure truss after the installation is completed
