Description

Technical Field

[0001] The invention belongs to the technical field of railway line maintenance, and in particular relates to a road-rail dual-purpose rail welding vehicle. Background Art

[0002] Modern railway transportation is developing in the direction of high speed, heavy load and large volume. Seamless lines are being used more and more. Seamless lines eliminate the rail welding joints of ordinary lines, reduce the impact and vibration of trains, and extend the service life of wheel-rail components. The problem that needs to be solved urgently in the laying of seamless railways is various rail welding problems. Therefore, rail welding technology is the key to achieving high-speed, heavy-load, large-volume and safe railway transportation. At the same time, for existing railways, rail welding technology is also needed in daily maintenance and repair operations. For example, when the rails on the existing line are broken, short rails need to be inserted and re-welded to achieve the purpose of permanent treatment.

[0003] At present, there are three main methods commonly used for domestic railway rail welding, namely flash welding, pneumatic welding and thermite welding; flash welding is divided into fixed and mobile types. Fixed flash welding is mainly used for rail welding in the factory, and mobile flash welding, pneumatic welding and thermite welding are mainly used for rail welding on site; mobile flash welding has the characteristics of high efficiency and high quality, and is currently the most widely used rail welding method, but mobile flash welding often requires the dispatch of large self-propelled rail welding vehicles or rail vehicles to tow containerized rail welding vehicles for rail welding operations, with high equipment cost and weak adaptability, and is mainly used in mainline railways. Pneumatic welding has the characteristics of low equipment cost, fast welding speed and good welding quality, but it has very strict requirements for the cross-section treatment of the joint before welding, and the welding process is easily affected by the environment and the operating level of the personnel. The joint quality fluctuates greatly and is difficult to control. It is generally only used as a supplement to flash welding, and is used for the welding of joint joints during the on-site laying of long rails or the welding of joints of seamless lines across sections. Thermite welding equipment is simple and easy to operate, and is very suitable for repairing broken rails and welding rails in switch areas with limited space. However, its welding strength is low, the quality is unstable, the breakage rate is high, and the overall performance is poor.

[0004] Based on the shortcomings of large-scale rail welding vehicles in mainline rail welding operations, such as high equipment cost, weak adaptability, low flexibility, and low strength and unstable quality of rail welding in the turnout area, it is necessary to design a dual-purpose rail welding vehicle that can perform rail welding operations both on the mainline and in the turnout area, based on flash welding, and has the characteristics of low equipment cost, mobility and flexibility, high quality and high efficiency, so as to reduce the number of railway turnout rail welding operators, improve the quality and efficiency of rail welding operations, and reduce the safety hazards of railway driving.
