Description

Due to the internal structure of the turnout, the complex working conditions of the turnout pre-paving site and other reasons, the welding machine cannot effectively clamp the to-be-welded rail, and cannot weld the rail joints near the position of the frog, the point rail and the like with small rail-to-rail distance. Therefore, at present, for the welding of the rail joints of the station line and the turnout, due to the complex working conditions of the turnout pre-paving site, the complicated process of the operation equipment reaching the to-be-welded position, the manual operation with a small machine is mainly used, the aluminum heat welding is used to realize the welding of the rail joints in the turnout area, and the weld joint is of cast structure. This operation mode requires a large number of workers, has high labor intensity and high labor cost, and the welding quality of the welding position is uneven due to the different experiences of the workers. Compared with the flash welding and the gas pressure welding which can realize automatic control, the weld joint of the manual aluminum heat welding has poor comprehensive mechanical properties, high rail breaking rate and low service life. Replacing the aluminum heat welding with the flash welding or the gas pressure welding to realize the rail welding in the turnout area is beneficial to improving the train safety of the line.

[0071] In a specific embodiment, the application provides a rail welding equipment for both road and railway, which comprises a loading platform 211, a welding device 214 and a hoisting device 213. The loading platform 211 comprises a chassis 2112, a vehicle frame 2111 and related systems and accessories. The chassis 2112 is located below the vehicle frame 2111 and comprises a steel wheel running device 21122 and a track running device 21121. The rail welding equipment for both road and railway can switch between running on a railway and running on a flat road through the steel wheel running device 21122 and the track running device 21121, so that the rail welding equipment can run to the position of a frog, a point rail, etc. in a turnout for rail welding, and is suitable for complex working conditions. The vehicle frame 2111 is used for carrying a cab, a power system 217, a hydraulic system 218 and an electrical system 219. The related systems and accessories comprise the power system 217, the hydraulic system 218 and the electrical system 219, etc. The power system 217 comprises a charger, a storage battery, an electrical control cabinet and a generator. The charger is connected to an external power supply and charges the storage battery. The voltage of the storage battery is the voltage available for the welding machine 2141 system and the hydraulic system 218. Under normal circumstances, the storage battery is charged by the charger through an external power supply. When it is inconvenient to charge the storage battery through an external power supply and there is a construction demand, the storage battery can be charged by the generator. The hydraulic system 218 is used to provide hydraulic power for the track running device 21121, the steel wheel running device 21122, a rotating device 212, the hoisting device 213, a rail lifting device 216 and the welding machine 2141. The hydraulic system 218 is provided with an emergency pump, which can perform emergency operation or emergency parking when a pump station fails. The electrical system 219 is used to provide electrical control for the track running device 21121, the steel wheel running device 21122, the rotating device 212, the hoisting device 213, the rail lifting device 216 and the welding machine 2141, etc. The hoisting device 213 is used to hoist the welding machine 2141 and can assist in supporting the whole machine under uphill or downhill tracks or other harsh working conditions, thereby improving the flexibility and off-road capability of the whole machine.
