Background

The steel rail flash welding is the most widely applied one of the domestic steel rail welding methods, the welding method has high automation degree, the treatment requirement on the steel rail before welding is lower, the obtained joint has stable quality, and the on-line rail breakage rate is extremely low. The welding method is one of pressure welding, and has the basic principle that the two ends of a steel rail to be welded are heated by forming lintel blasting through current, upsetting force is applied after a certain welding temperature field is formed, and finally the welding of the steel rail is realized.

The flash welding of steel rails can be divided into two major categories, base welding and mobile welding, according to the difference of the operation fields. In the rail moving flash welding, because the equipment is small, the rail is generally operated in a way of clamping the rail by the rail web, which is greatly different from the welding of most bases. The pre-welding rust removal equipment for the mobile flash welding of the steel rail needs to remove rust on four rail waist surfaces of two steel rails to be welded so as to reduce the contact resistance between the rail waist and a welding machine and realize flash welding.

The length of polishing before welding has certain demand, and this length is generally about 600mm, and these equipment do not solve the problem of emery wheel axial automatic movement in polishing, need the operation personnel to promote constantly and advance. 3. The depth of polishing, namely the depth of feed, is adjusted by manual machinery or is directly manually controlled, so that the operation difficulty of operators is increased. 4. Most of the grinding devices adopt traditional power, and the used common three-phase motor or internal combustion engine is used as power, so that fossil energy such as diesel oil is inevitably adopted on a construction site, the pollution to the environment is serious, and the harm to the health of operators can be caused under a closed environment.
