Steel rail flash welding machine and container type steel rail flash welding equipment

Abstract

The invention provides a steel rail flash welding machine which comprises fulcrums arranged thereon, at least two steel rail clamping mechanisms arranged on the corresponding fulcrums, a flash welding transformer and an upset forging actuating mechanism. Each steel rail clamping mechanism comprises an operating mechanism, two lever structures and two connecting rod pieces, wherein the operating mechanism is provided with an operating rod capable of vertically applying force or actuating; the two lever structures can pivot around the fulcrums, and the lower end of each lever structure can loosen or clamp a steel rail; and one end of each connecting rod piece is pivotally connected with a common first pivot point on the operating rod, and the other end of the connecting rod piece is pivotally connected with one of second and third pivot points lower than the first pivot point on the corresponding lever structure, and the operating rod vertically applies the force to or actuates the connecting rod pieces, so that the lower ends of the lever structures loosen or clamp the steel rails. The invention also provides container type steel rail flash welding equipment with the steel rail flash welding machine.

Description

technical field [0001] The invention relates to the field of rail flash welding, in particular to a rail flash welding machine. In addition, the invention also relates to a container-type rail flash welding equipment with a rail flash welding machine. Background technique [0002] The seamless lines of railways are mostly welded by multi-section steel rails. Rail welding is generally classified as factory welding or on-site (on-line) welding. For field welding there are generally four types, namely flash welding, gas pressure welding, thermite welding and narrow gap arc welding. Among them, the quality of rails welded by mobile flash welding is the most stable, so it has become the main means of on-site rail welding. [0003] The basic principle of flash welding is to make the ends of the spliced ​​two rails short-circuit and generate heat, and then when they are heated to a certain temperature, the softened ends are quickly pulled together (upset) to complete the welding...

AI Technical Summary

Problems solved by technology

In this kind of container-type flash welding equipment, the hydraulic pump station and the electric control cabinet are in the same compartment. Due to the high operating temperature of the hydraulic pump station, sometimes it is above 60 degrees, and the noise of the pump station is very loud, which is harmful to the electrical equipment. The electrical components in the control cabinet have adverse effects, and its boom is not retractable. When welding on the line, it is difficult to align the rail when the welder is placed on the rail to be welded, because the boom cannot be longitudinally along the rail. adjust
