Processing method of large-scale suspension bridge vice saddle

Abstract

The invention discloses a processing method of a large-scale suspension bridge vice saddle. The vice saddle is constituted by combining and welding a saddle bow and a saddle body, wherein, the saddlebody is constituted by combining and welding a base block and a rib plate; and the bottom surface of the base block is provided with a key slot. The processing steps are as follows: (1) respectively processing well the saddle bow and the base block on the numerical control machine tool rotation workbench, wherein, the key slot on the base block is not processed temporarily; (2) welding the rib plate on the base block to form the saddle body on the ground workbench; (3) combining and welding the saddle bow and the saddle body to a whole on the ground workbench; and (4) processing the key slot on the ground workbench. The method can satisfy processing requirements by utilizing conventional general equipment without adding large-scale equipment, thus having prominent economic effect.

Description

technical field [0001] The invention relates to a suspension bridge, in particular to a processing method for a loose cable saddle of a large suspension bridge. Background technique [0002] In modern bridge construction, the suspension bridge has become the first choice for long-span bridges due to its large spanning capacity, good seismic performance, and beautiful appearance. [0003] The loose cable saddle is an important force-bearing component of the suspension bridge, and is generally welded by casting the saddle head 1 and the saddle body, such as figure 1 , figure 2 shown. [0004] Small and medium sling saddles have small structure and light weight, and can be processed with conventional equipment in the heavy industry. The traditional manufacturing process is: the saddle head and saddle body are roughly machined and then welded into a whole, and finally the whole is finished. [0005] With the rapid development of transportation and the continuous improvement ...

AI Technical Summary

Problems solved by technology

As the span of the suspension bridge increases, in order to ensure the strength of the loose cable saddle, its structural size and weight increase simultaneously. The weight of a large loose cable saddle exceeds 100 tons, which brings about the problem of insufficient equipment capacity in the traditional heavy industry industry. The geometric size and bearing capacity of the table are limited, which cannot meet the overall processing requirements of the loose cable saddle. If the simple increase in investment is used to transform or update equipment and workshops, and improve the processing capacity, it is bound to greatly increase the manufacturing cost of the loose cable saddle. bridge cost
