[0002] Railway tracks are generally made up of multiple rails laid end to end, and two adjacent rails are generally connected by welding. At present, there are four main methods of rail welding at home and abroad: flash welding, gas pressure welding, thermite welding and narrow gap arc welding. In related technologies, welding between adjacent rails is generally achieved by a rail welding car.

[0003] At present, pneumatic rail welding vehicles are usually used to weld new rails that are inserted into the section to be replaced. In this process, the movement of new and old rails still needs to rely on manual handling. At the same time, one bogie of the pneumatic rail welding vehicle needs to be supported to be separated from the rails, which is not only labor-intensive, but also takes a certain amount of time. In addition, there is no separation of people and vehicles during the operation of the pneumatic rail welding vehicle, which poses a safety hazard. In addition, there are the following problems during welding: one of the bogies of the rail welding vehicle is pressed on the rail, and there is a relative displacement between the rail and the bogie during welding top forging; after the first sawing welding is completed, the welding position has not been aged for a certain period of time, and the rail welding vehicle passes through the first welding position, which is easy to have an adverse effect on the welding point; when traveling from the first welding point to the second welding point, the fasteners of one side of the rail are completely loosened, and there are risks of vehicle overturning and derailment for super-high lines.

When the rail welding vehicle is operating, there is no need to lift the bogie on the welding joint side to separate from the rails, which effectively reduces safety hazards. At the same time, the rail welding vehicle can also operate on super-elevation lines, realizing the high-speed rail super-elevation working conditions, and has good adaptability.

The first loading platform has a simple structure, is easy to use, has a strong carrying capacity and is easy to maintain. The power room provides a power source for the welding operation, the operation room can control the travel and braking of the whole vehicle, and control the start and stop and operation of each component, and the welding machine hoisting device can hoist the welding machine to the welding position of the adjacent track, so that the rail welding vehicle can weld the rails of the adjacent track on the adjacent track, thereby realizing the adjacent line welding of the rail welding vehicle.

[0037] Furthermore, the welding rail vehicle 2 also includes: two slide grooves 25, which are respectively arranged on both sides of the first loading platform 21 and extend along the length direction of the vehicle body, the notch of each slide groove 25 is upward, and at least one connecting component 26 is slidably arranged in each slide groove 25; a sliding ceiling 27, which is connected to the top of each connecting component 26, and the sliding ceiling 27 is located above the power room 22, the operation room 23 and the welding machine hoisting device 24. When each connecting component 26 moves in the same direction in the corresponding slide groove 25, it can drive the sliding ceiling 27 to move in the same direction. During operation, the sliding ceiling 27 slides in the direction away from the welding machine hoisting device 24. When the sliding ceiling 27 slides into place, the sliding ceiling 27 is located above the power room 22 and the operation room 23, making room for the welding machine hoisting device to work; the ceiling 28 is arranged on the top of the operation room 23, and is heat-insulated to provide a good working environment for the staff.

[0038] Furthermore, the first loading platform 21 is a NX70 flatbed truck, or a loading platform with a structure and function similar to that of a flatbed truck.

[0039] Furthermore, the power room 22 adopts a box-type structure to integrate various power source systems for easy lifting.

[0040] Specifically, the power room 22 is equipped with an internal combustion engine or a new energy power system to provide power for welding operations.

[0041] As another embodiment, the power room 22 integrates the power source systems in a load-bearing manner with protective devices to facilitate lifting.

[0043] Specifically, the electrical control cabinet is electrically connected to the first crane, the leveling cylinder and the hydraulic outriggers in the welding machine hoisting device. The electrical control cabinet can control the travel and braking of the whole vehicle, the rotation and lifting of the first crane, the lifting and lowering of the leveling cylinder, and the lateral movement and lowering of the hydraulic outriggers. During operation, the above operations can be achieved by controlling the buttons on the electrical control cabinet or by remote control, which is simple and convenient to operate.

[0044] Specifically, two connecting components 26 are slidably disposed in each sliding groove 25, which effectively increases the stability of the connection between the connecting components and the sliding ceiling.

[0045] Figure 5 This is a structural schematic diagram of a welding machine hoisting device for a rail welding vehicle provided in an embodiment of the present application. Figure 6 This is a front view of a welding machine hoisting device for a rail welding vehicle provided in an embodiment of the present application. Figure 7 A top view of a welding machine hoisting device for a rail welding vehicle provided in an embodiment of the present application, as shown in FIG. Figure 5-7 As shown, further, the welding machine hoisting device 24 includes: a fixed base 241, which is arranged on the first loading platform 21 and is used to carry the leveling mechanism, the welding machine and the first hoist; a leveling mechanism 242, which is arranged on the fixed base 241 and is used to level the welding machine hoisting device 24; a welding machine 243, which is movably arranged at one end of the fixed base 241 and is used to weld the joint between the new rail and the existing rail; a first hoist 244, which is arranged in the middle of the leveling mechanism 242 and is used to hoist the welding machine 243. The first hoist can be used to hoist the welding machine from the fixed base to the working position of the adjacent track to be replaced, and the welding machine after work can also be hoisted to the next working position, and the welding machine after work can also be hoisted to the fixed base 241, and the first boom of the first hoist 244 is a retractable boom, which expands the working range of the first hoist.

[0046] Specifically, the rotating device on the first crane 244 can drive the first boom to rotate freely 360°, making the first crane more practical. During operation, the first crane lifts the welder and rotates it to a suitable angle so that the welder is located above the working position to be welded. Then, the welder is dropped back to the working position of the operation line by the first crane. The welder welds the position to be welded. After the welding operation is completed, the first crane is driven to hoist the welder onto the rail welding vehicle. The rail welding vehicle in the present application realizes the welding of the rails on the adjacent tracks. At the same time, it eliminates the adverse effects of the rail welding vehicle on the operation line and improves the construction quality.

[0047] Specifically, the welding machine 243 uses a flash normalizing integrated machine and its supporting devices to perform pre-welding treatment, welding and post-welding treatment on the rails to be welded, thereby improving work efficiency and saving costs.

[0048] Specifically, the first crane 244 also includes hydraulic legs. After the first crane hoisting welder is rotated to a suitable angle, the hydraulic legs thereon move laterally downward to provide auxiliary support for the first crane and enhance the stability of the device.

[0049] As an implementation manner, the welding machine 243 is disposed at one end of the fixed base 241 away from the operating room 23 , and the hook of the first crane 244 is located above the welding machine 243 .

Figure 8 As shown, further, the leveling mechanism 242 includes: a leveling base 2421, which is arranged on the fixed base 241; two leveling cylinders 2422, which are vertically symmetrically arranged on both sides of the leveling base 2421, and are used to drive the leveling base 2421 to swing up and down like a seesaw; two hydraulic legs 2423, which are symmetrically arranged at both ends of the leveling base 2421, and can move laterally and can also be lifted and lowered vertically. During operation, the two hydraulic legs 2423 move laterally and descend on the sleepers or the roadbed to assist in supporting the rail welding vehicle and prevent the rail welding vehicle from overturning.

[0051] When the rail welding vehicle of the present application is operating on a superelevation line, the leveling mechanism on it can play a leveling role, ensuring that the hydraulic legs, the first crane, and the welding machine on it are all in a horizontal state, ensuring the efficiency and safety of the operation. In addition, according to actual needs, the leveling mechanism is not limited to flatbed vehicles, and can also be used in conjunction with automobile transportation.

[0052] Furthermore, each rail transport vehicle 1 includes: a second loading platform 11, which is used to load new rails. Bogies that cooperate with the rails are arranged at both ends of the bottom of the second loading platform, which are used to drive the second loading platform to move on the track. The second loading platform has a simple structure, is easy to use, has a strong load-bearing capacity and is easy to maintain; at least one second crane 12 is arranged on the second loading platform 11, which is used to lift the new rails from the second loading platform 11 to the corresponding position of the operating area of ​​the adjacent track to be replaced, and the second boom of each second crane 12 is a retractable boom, which expands the working range of the second crane.

[0053] Specifically, the rotating device on the second crane 12 can drive the second crane arm to rotate 360 ​​degrees freely, making the second crane more practical. During operation, the second crane lifts the new rail and rotates the new rail to the top of the corresponding position of the adjacent track section to be replaced, and then the new rail is dropped back to the corresponding position of the operation area by the second crane.

Fig.10 As shown, as another embodiment, a second crane 12 is provided at both ends of each rail transport vehicle 1. This expands the use scope of the second crane.

[0056] In specific implementation, at least one rail transport vehicle 1 without new rails can be connected to the rear end of the rail welding vehicle 2 to load the dismantled old rails, thereby saving costs.

[0057] The new rails in the present application are lifted or dropped back to the designated position by the second crane on the rail transport vehicle, and the dismantled old rails can also be lifted by the second crane on the rail transport vehicle to the rail transport vehicle or the old rail recovery vehicle, thereby realizing cross-line transportation, reducing manual participation, alleviating manual labor intensity, and improving operation safety.

[0058] Furthermore, the second loading platform 11 is a NX70 flatbed truck, or a loading platform with a structure and function similar to that of a flatbed truck.

[0059] Specifically, each rail transport vehicle also includes a control component, which is electrically connected to the second crane. The control component can be used to control the boom of the second crane to rotate, extend, clamp the new rail and place the new rail in the rail bearing groove of the old rail on the rail section to be replaced, and control the hydraulic support leg on the second crane to move horizontally and descend, which is easy to operate.
