Description

Technical field:

[0001] The invention belongs to the technical field of railway rail air pressure welding machine control, in particular to a control method and equipment for a mobile rail air pressure welding machine. Background technique

[0002] In the prior art, a general complete set of mobile rail pressure welding machine is composed of a crimping machine, a high-pressure oil pump, a heater, a tumor pushing device, a gas flow control box and a cooling water circulation system. The mobile rail air pressure welding machine is divided into the clamping waist type and the clamping rail bottom type. The crimping machine is mainly to clamp the two welded steel rails, fix their relative positions, provide the upsetting force during the heating process of the air pressure welding, and ensure the joints of the rails. End face welding and post-welding to complete the push-button requirements. This air pressure welding machine can pass TB / T2622.1-95 "Mobile Rail Air Pressure Wel...
