A special aircraft for intelligent repair of railway coupler tongue

Abstract

The invention discloses a special intelligent repair machine for a railway coupler knuckle which comprises a base, stand columns, a slide rail, a coupler knuckle positioning support, a welding assembly, a milling assembly and a control system. The slide rail is installed on the base through the stand columns. The coupler knuckle positioning support is arranged under the base and penetrates out of the base to be used for fixing a coupler knuckle. The special repair machine is high in practicability, high in intelligence degree and high in efficiency, welding repair and milling forming are integrated, and the procedure that the coupler knuckle is machined on a coupler knuckle profiling milling machine special for coupler knuckles after welding repair is completed is omitted, the welded workpiece can be repaired continuously and formed at a time, materials and manpower are saved, welding materials are saved by 70% or over, the maintenance cost is lowered, railway vehicle coupler knuckle detecting and remanufacturing are achieved, and the flexibility of coupler knuckle repair is greatly improved while the intelligence level of coupler knuckle repair is increased.

Description

technical field [0001] The invention relates to the technical field of special planes, in particular to a special plane for intelligent repair of railway coupler knuckles. Background technique [0002] In recent years, the railway has undergone six major speed increases. With the introduction of the strategy of "high-speed rail going global", the high-speed rail industry has developed rapidly and achieved remarkable results in the world. After the speed increase, how to make the train run more safely and at high speed , the government and the railway department attach great importance to it. At the same time, the maintenance volume of various components has increased greatly, which has also become a problem that needs to be faced. There have been more and more problems caused by the speed-up of railway vehicles. The worn parts on the train have been worn too fast, especially the movable parts such as the hook tongue and the brake beam between the carriages. , brake failure,...

Problems solved by technology

[0004] At present, most of the repairs of vulnerable parts of railway trains are done manually, which has low efficiency and poor quality. Labor costs remain high

[0005] The existing patent 00226356.4 discloses a head of automatic submerged arc welding machine with poles of railway knuckle, which solves the technical problem of welding the head of submerged arc surfacing welding with poles in a narrow space, and enables the technology of submerged arc surfacing welding with poles in It is used in surfacing welding repair of railway coupler knuckle, but due to the thick welding wire used and the large heat input, the machining allowance after welding is large, wasting welding materials, workers and man-hours, and the thickness of the surfacing layer cannot be accurately controlled And the position of surfacing welding, resulting in the need to manually repair the unwelded position after welding, which affects the welding quality. After welding, it must be cut into a single knuckle with a toothless saw. Noise and dust permeate the entire workshop during cutting, causing serious environmental pollution.
