Steel track welding platform with adjustable working surface

Abstract

The invention relates to steel track welding equipment, in particular to a steel track welding platform with an adjustable working surface. The steel track welding platform is provided with a base and a platform rack, the platform rack is mounted on the base via a hinging mechanism, the hinging mechanism is symmetrically arranged in the middle of a space between two sides of the platform rack, and the platform rack is connected with a driving mechanism which drives the platform rack to swing. The steel rack welding platform has the following advantages that energy is saved, adjusting ability is good, operation is simple, stress on the platform rack is balanced, manufacturing cost is low, assembly and disassembly are convenient, a good swinging effect can be realized, stress on the base is balanced, and stability of the platform rack is high.

Description

technical field [0001] The invention relates to rail welding equipment, in particular to a rail welding platform with an adjustable working face. Background technique [0002] The seamless lines of railways are mostly welded by multi-section steel rails. Rail welding is usually classified as factory welding or on-site (on-line) welding. For on-line welding, in order to avoid the harm caused by centrifugal force, a certain slope will be provided on the side of the roadbed at the bend of the railway. Welding on the platform on the curve line will cause the welding platform to be out of level due to the influence of the slope, thus causing welding defects. [0003] One end of the existing rail welding platform is hinged on the base, and the other end is connected to one or more hydraulic cylinders, the one or more hydraulic cylinders are hinged on the base, and the base usually adopts a steel structure. If one hydraulic oil cylinder is used, the pressure on the base is relat...

AI Technical Summary

Problems solved by technology

If one hydraulic cylinder is used, the pressure on the base will be greater, which will easily cause yield deformation and affect the levelness of the platform; if multiple hydraulic cylinders are used, the cost will be high and disassembly will be difficult

In addition, the structure is rotated and adjusted for a long time, and the force is uneven at various angles. Under alternating loads, it is prone to fatigue failure, crack expansion, causing deformation or even collapse of the base, which eventually leads to the unevenness of the platform and the decline in the welding quality of the rail.
