[0002] The operating mileage of high-speed railways has reached 45,000 kilometers. As the service life of some lines increases, fatigue damage to the rails is quite common. For the track replacement construction of high-speed railways, it is necessary to complete all the procedures of track replacement within a single window point, including unloading of new rails, replacing old rails with new ones, recycling of old rails, stress relief and locking, rail welding, etc., and ensure that the materials are clean and the site is clear after the work is completed.

[0003] At present, the rail replacement construction of the operating railway is carried out based on the main line, that is, the operation of the engineering train and the rail replacement operation are all carried out on one railway line. The new long rails are unloaded by "road unloading method". The long rails are dragged out from the long rail conveyor. When the rear end of the rail enters the on-board fixed flash welder, the long rail train stops, and the towing device is used to drag another pair of long rails from the long rail conveyor. The on-board fixed flash welder is used to weld the first pair of rails and the second pair of rails into a longer length to form a new long rail. The front end of the new long rail is placed on the outside of the running track rail, and the existing long rail is pulled out of the rail groove by the rail replacement trolley and placed on the inside of the railway line rail. At the same time, the new long rail is put into the rail groove to complete the replacement of the old and new long rails; the train is reversed and the rail replacement trolley is used to shovel and recycle the rails to be replaced. In the future, stress relief and locking, rail locking joint welding and other work will continue until all processes are completed.

The front end of the new long rail 5 is placed on the outside of the running track rail, and the long rail 4 to be replaced is pulled out of the bearing rail groove by a rail-changing trolley and placed on the inside of the railway line rail. At the same time, the new long rail 5 is inserted into the bearing rail groove to complete the replacement of the old and new long rails. The train is reversed and the rail-changing trolley is used to shovel and recycle the rail to be replaced. In the future, the welding of rail unit joints, stress relief and locking, and welding of rail locking joints will continue until all processes are completed.

[0031] The various procedures of track replacement construction are carried out alternately on the railway line in the track replacement section, involving the investment of a large amount of equipment and personnel, making the construction organization difficult; railway equipment vehicles run on railway lines with incomplete fasteners, posing a high safety risk; the various procedures are carried out step by step and cannot be carried out simultaneously, resulting in low construction efficiency.

[0032] It should be noted that the "main line 40" in this application refers to the channel for the operation of major equipment and logistics, the "adjacent line" in this application refers to the route for the implementation of the main track-changing task, the "track-changing starting point" in this application refers to the starting position of the existing rail 6 that is planned to be replaced or needs to be replaced, the "track-changing operation section" in this application refers to the section from the track-changing starting point to the track-changing end point, and the "track-changing end point" in this application refers to the end position of the existing rail 6 that is planned to be replaced or needs to be replaced. The "front end" in this application refers to the end close to the track-changing end point in the track-changing operation section, and the "rear end" in this application refers to the end close to the track-changing starting point in the track-changing operation section.

[0033] The rail replacement device provided by the present invention is firstly provided with a long rail train set 2 and a rail welding unit 3, wherein the long rail train set 2 is arranged on the main line 40, and the long rail train set 2 travels on the main line 40, and is used to recover the long rails 4 to be replaced on the adjacent line 50, and lay new long rails 5 on the adjacent line 50, and the rail welding unit 3 is arranged on the adjacent line 50, and the new long rails 5 are welded to the ends of the existing rails 6 by the rail welding unit 3, thereby realizing the recovery, laying and welding of the long rails 4 to be replaced. The rail replacement construction method provided by the present invention utilizes the advantages of the dual-channel construction of the main line 40 and the adjacent line 50, completes the replacement task of the long rails on the adjacent line 50, recovers the long rails 4 to be replaced on the adjacent line 50 by the long rail set, and lays new long rails 5 on the adjacent line 50, and simplifies the construction process. It can be seen that compared with the prior art, the rail replacing device in the embodiment of the present invention can reduce the interference of process alternation, reduce the difficulty of construction organization, improve the efficiency of track replacement construction, reduce driving safety risks, and give full play to the effectiveness of the invested equipment.

[0034] In the above structure, as one of the specific implementations, the long rail train group 2 in the embodiment of the present invention includes: a first tractor 21; a first cross-line rail-changing vehicle 22, a first pusher 23 and a rail transport vehicle 24 at the rear end of the first tractor 21 in sequence, the first cross-line rail-changing vehicle 22 is used to lift the rear end of the long rail 4 to be replaced at the starting point of the rail change, and the first cross-line rail-changing vehicle 22 is provided with a rail-pushing device. During the movement, the first tractor 21 drives the long rail 4 to be replaced through the rail-pushing device and the first pusher 23 into the rail transport vehicle 24; a second pusher 25 and a second cross-line rail-changing vehicle 26 are arranged at the rear end of the rail transport vehicle 24 in sequence, and the new long rail 5 is placed in the rail transport vehicle 24, the second pusher 25 is used to push the new long rail 5 to the second cross-line rail-changing vehicle 26, and the rear end of the new long rail 5 is pushed into the starting point of the rail change of the adjacent line 50 through the rail-pushing device placed on the second cross-line rail-changing vehicle 26.

[0035] It should be noted that the rail transport vehicle 24 in the embodiment of the present invention is used to place and transport the recovered long rails 4 to be replaced and the new long rails 5, and the long rails 4 to be replaced and the new long rails 5 are arranged side by side on the rail transport vehicle 4.

[0036] The first tractor 21 is used to provide power for the long rail train set 2, and the first cross-line rail changing car 22, the first push car 23 and the rail transport car 24 are used to recover the long rail 4 to be replaced located on the adjacent line 50. The first cross-line rail changing car 22 is provided with a rail derailing device. The first tractor 21 drives the first cross-line rail changing car 22 to move to the rail changing starting point of the main line 40, and the long rail 4 to be replaced located at the rail changing starting point of the adjacent line 50 is lifted by the first cross-line rail changing car 22, and the long rail 4 to be replaced is shifted to the main line 40 by the rail derailing device on the first cross-line rail changing car 22. As the long rail train set 2 moves toward the rail changing end point, the long rail 4 to be replaced passes through the rail derailing device and the first push car 23 and is transported to the rail transport car 24, and the long rail 4 to be replaced is transported by the rail transport car 24.

[0037] The rail transport vehicle 24, the second push vehicle 25 and the second cross-line rail changing vehicle 26 are used to transport and lay the new long rail 5. The new long rail 5 is arranged in the rail transport vehicle 24. When the second cross-line rail changing vehicle 26 moves to the rail changing starting point, the first tractor 21 stops moving, and the new long rail 5 in the rail transport vehicle 24 is pulled out by the second push vehicle 25 and pushed to the rail shifting device on the second cross-line rail changing vehicle 26. The end of the new long rail 5 is shifted to the rail changing starting point in the rail bearing groove on the adjacent line 50 by the rail shifting device, and the end of the new long rail 5 is fixed. The first tractor 21 moves toward the direction of the rail changing end point, driving the second push vehicle 25 and the second cross-line rail changing vehicle 26 to move until the new long rail 5 completely falls into the rail bearing groove of the adjacent line 50, thereby completing the laying of the rail.

[0038] Furthermore, during the movement of the long rail train set 2 on the main line 40, the first cross-line rail changing vehicle 22, the first pushing vehicle 23 and the rail transport vehicle 24 located at the front end are used to recover and transport the long rails 4 to be replaced on the adjacent line 50, while the second pushing vehicle 25 and the second cross-line rail changing vehicle 26 are used to lay the new long rails 5 in the rail transport vehicle on the adjacent line 50. The actions of recovering the old rails and laying the new rails can be carried out simultaneously, saving operation time, reducing alternating interference between working processes, and improving construction operation efficiency.

[0039] In the above structure, as one of the specific implementations, the rail welding unit 3 in the embodiment of the present invention includes a first welding rail group 31 and a second welding rail group 32, wherein the first welding rail group 31 is arranged at the starting point of the rail change of the adjacent line 50, and the first welding rail group 31 is used to weld the rear end of the new long rail 5 to the first end of the existing rail 6, and the second welding rail group 32 is arranged at the end point of the rail change of the adjacent line 50, and is used to weld the front end of the new long rail 5 to the second end of the existing rail 6.

[0040] When the new long rail 5 is laid, the first welding rail group 31 and the second welding rail group 32 are constructed simultaneously to weld the two ends of the new long rail 5 to the existing rail 6. On the one hand, the first welding rail group 31 and the second welding rail group 32 are both arranged on the adjacent line 50 and will not conflict with the movement of the long rail train group 2 on the main line 40; on the other hand, the first welding rail group 31 and the second welding rail group 32 can weld the two ends of the new long rail 5 at the same time, further improving the construction efficiency.

[0041] Furthermore, as one embodiment, the first welding rail set 31 in the embodiment of the present invention includes a second tractor 311 and a first welding rail device 312, and the second tractor 311 drives the first welding rail device to travel on the adjacent line 50. The second welding rail set 32 ​​in the embodiment of the present invention includes a third tractor 321 and a second welding rail device 322, and the third tractor 321 drives the second welding rail device 322 to travel on the adjacent line.

[0042] In the above structure, as one of the preferred embodiments, the new long steel rail 5 in the embodiment of the present invention includes at least two long rail units, and the two long rail units are welded by cross-line rail welding equipment. The cross-line rail welding equipment is arranged on the main line 40 and is used to weld the two long rail units located on the adjacent line 50.

[0043] The cross-line rail welding equipment runs on the main line 40, and the cross-line rail welding equipment is arranged at the rear end of the long rail train group 2. After the long rail train has laid two long rail units, the long rail unit located on the adjacent line 50 can be welded by the cross-line rail welding equipment. On the one hand, the cross-line rail welding equipment runs on the main line, and the rail welding unit 3 runs in the unconstructed area on the adjacent line 50, which is safer. On the other hand, after the long rail train group 2 has replaced the two long rail units, the cross-line rail welding equipment can be used to weld the two adjacent long rail units, and the construction efficiency is higher.

[0044] like Figures 10 to 12As shown, the present invention also provides a specific structure of a cross-line rail welding device, which includes a bearing platform 10, a hanger mechanism 20 installed on the bearing platform 10, and a welding device 30 connected to the hanger mechanism 20, wherein the hanger mechanism 20 can drive the welding device 30 to switch between the direction of the main line 40 and the direction of the adjacent line 50; the hanger mechanism 20 includes a mounting seat 201, a swivel arm 202, a support arm 203, and a telescopic arm 204. Among them, the mounting seat 201 is rotatable relative to the bearing platform 10; the swivel arm 202 is rotatably connected to the mounting seat 201; the support arm 203 is rotatably connected to the side wall of the swivel arm 202, and has an unfolded state and a folded state relative to the swivel arm 202; the telescopic arm 204 is movably connected to one end of the swivel arm 202 away from the mounting seat 201, and includes a first telescopic arm 2041 and a second telescopic arm 2042 arranged in sequence. It can be explained that the main line 40 refers to the track line where the rail train 2 is located, and the adjacent line 50 refers to the track line adjacent to the main line 40. In some optional embodiments, one end of the mounting base 201 is rotatably connected to the swivel arm 202, and the other end is connected to a telescopic support rod 205, the telescopic end of the telescopic support rod 205 is connected to the swivel arm 202, and provides additional support for the telescopic arm 204 after the swivel arm 202 is extended. The support arm 203 includes a first support arm 203 and a second support arm 203, and the second support arm 203 is telescopically arranged relative to the first support arm 203, so as to adjust the height of the welding equipment during operation.

[0045] The cross-line rail welding equipment 1 includes a bearing platform 10, a hanger mechanism 20 installed on the bearing platform 10, and a welding device 30 connected to the hanger mechanism 20; the hanger mechanism 20 includes a mounting seat 201, a rotating arm 202, a support arm 203 and a telescopic arm 204; wherein the mounting seat 201 is rotatable relative to the bearing platform 10 so that the hanger mechanism 20 can drive the welding device 30 to switch between the direction of the main line 40 and the direction of the adjacent line 50; the rotating arm 202 is rotatably connected to the mounting seat 201 so that the welding device can be moved away from the bearing platform under the action of the rotating arm 202 10 is aligned with the target welding position or is placed above the supporting platform 10 close to the supporting platform 10; the setting of the support arm 203 being rotatably connected to the side wall of the rotating arm 202 makes the support arm 203 have an unfolded state and a folded state relative to the rotating arm 202; the setting of the movably connected telescopic arm 204 to the end of the rotating arm 202 away from the mounting seat 201 makes the telescopic arm 204 have an extended state and a contracted state relative to the rotating arm 202, and the telescopic arm 204 includes a first telescopic arm 2041 and a second telescopic arm 2042 which are arranged in sequence, which can expand the welding operation range and realize adjacent line welding.

[0046] The cross-line rail welding equipment provided in the embodiment of the present invention can realize both main-line welding and adjacent-line welding, so that it has a dual-line operation mode, which improves the flexibility of equipment construction. When adjacent-line welding is adopted, the number of installation and removal of temporary joints, rail buckle accessories and rollers can be reduced, thereby improving construction efficiency.

[0047] When welding the main line, the mounting seat 201 rotates so that the hanger mechanism 20 faces the main line 40, and the support arm 203 is in a folded state for welding operations. It should be further explained that the state of the telescopic arm 204 can be flexibly adjusted according to the distance of the target welding position. Specifically, when the target welding position is close, the telescopic arm 204 can remain in a retracted state to facilitate convenient and stable operation; and when the distance to the target welding position is far, the operator can adjust the length of the telescopic arm 204 to extend it to the required distance. This flexible telescopic design not only enhances the adaptability of the cross-line welding rail equipment 1, but also improves the efficiency of operation.

[0048] In some special cases, such as when the welding device 30 needs to be extended to a further position, the arm 203 can be adjusted to an extended state. In this state, the arm 203 will provide additional support and stability for the swivel arm 202 and the welding device 30, thereby ensuring that the equipment can withstand greater forces and loads during the welding process, and avoiding welding quality problems caused by unstable equipment.

[0049] During adjacent line welding, the mounting seat 201 rotates so that the hanger mechanism 20 faces the adjacent line 50, and the arm 203 is in an expanded state to provide necessary support to ensure the stability of the welding device 30. Since the target welding position of the adjacent line welding is usually far away from the support platform 10, it is necessary to adjust the telescopic arm 204 to the expanded state so that the welding equipment can perform welding operations on the target position to be welded. In order to achieve this, it is necessary to open the arm 203. The opened arm 203 is erected on the ground and can withstand the load from the swivel arm 202 and the welding device 30, thereby enhancing the stability of the entire welding system and preventing tilting or shaking during operation.

[0050] Adjacent line welding includes proximal welding and distal welding; during proximal welding, the first telescopic arm 2041 is in an extended state, and the second telescopic arm 2042 is in a retracted state; during distal welding, the first telescopic arm 2041 and the second telescopic arm 2042 are both in an extended state. It can be explained that proximal welding refers to welding operations on a track on the adjacent line 50 that is closer to the main line 40, while distal welding refers to welding operations on a track on the adjacent line 50 that is farther from the main line 40. During proximal welding, the first telescopic arm 2041 is in an extended state to bring the welding device 30 closer to the proximal welding position, while the second telescopic arm 2042 is in a retracted state to reduce the equipment's occupation of the surrounding space and avoid unnecessary vibration or offset during the welding process. During distal welding, the first telescopic arm 2041 and the second telescopic arm 2042 are both in an extended state so that the welding device 30 is close to the distal welding position to ensure that the distal welding operation can proceed smoothly.

[0051] In some optional embodiments, the cross-line rail welding equipment 1 is a double container structure, including a front container 60, a rear container 70 and a container transfer equipment, the front container 60 and the rear container 70 are both installed on the container transfer equipment, the bearing platform 10 is arranged at the bottom of the front container 60, the front container 60 is used to store the hanger mechanism 20 and welding equipment, hydraulic pump station, chiller and electrical cabinet, and the rear container 70 is used to store the generator set. Among them, the container transfer equipment can be a railway vehicle or a road vehicle, which is not specifically limited here. The bearing platform 10 can be the bottom of the front container 60, and the mounting seat 201 is a rotatable structure, which is installed on the bottom of the front container 60. The hydraulic pump station can provide power to the telescopic arm 204, the slewing arm 202, the support arm 203, etc. The chiller is used to cool the welding part to prevent overheating, the electrical cabinet is responsible for the power management and control of the equipment, and the generator set provides the required power for the entire equipment.

[0052] In the above structure, as one of the implementation modes, the cross-line rail welding equipment 1 in the embodiment of the present invention is also provided with a traction unit 7, and the traction unit 7 is used to drive the cross-line rail welding equipment 1 to move along the direction of the line 40.

[0053] An embodiment of the present invention provides an operation method of the cross-line rail welding device 1 based on any one of the above embodiments, the operation method includes main line welding and adjacent line welding, and the main line welding includes the following steps: Lower the swivel arm 202 so that the welding device 30 extends in the direction of the line 40; Adjust the first telescopic arm 2041 so that the welding device 30 is aligned with the joint of the rail to be welded and welded; The first telescopic arm 2041 and the welding device 30 are retracted to prepare for entering the next rail welding location.

[0054] In the above process, there is no need to open the support arm 203 to support the swivel arm 202 , and there is no need to adjust the second telescopic arm 2042 .

[0055] The present invention provides an operating method of a cross-line rail welding device 1, which adopts the cross-line rail welding device 1, and therefore at least has the technical effect corresponding to the embodiment of the cross-line rail welding device 1, which will not be repeated here. In addition, the operating method not only has the welding function of the main line, but also has the welding function of the adjacent line, which enhances the flexibility of construction. During the main line welding operation, the position of the welding device 30 can be flexibly adjusted according to the distance of the rail joint to be welded, thereby expanding the coverage of the welding device 30; during the adjacent line welding operation, there is no need to install temporary joints and rail buckle accessories, and the cross-line rail welding device 1 can complete the rail welding across the line, reducing the number of installation and removal of temporary joints, rail buckle accessories and rollers, thereby improving construction efficiency.

[0056] For further explanation, please refer to the attached Figure 5 As shown, the above operation method also includes adjacent line welding, and the adjacent line welding includes the following steps: Lower the swivel arm 202 to extend the welding device 30; Rotate the mounting seat 201 so that the hanger mechanism 20 faces the adjacent line 50; Lower the support arm 203 to support the swivel arm 202; Adjust the first telescopic arm 2041 so that the welding device 30 is aligned with the joint of the near-end rail to be welded and welded; Adjust the second telescopic arm 2042 so that the welding device 30 is aligned with the joint of the far end rail to be welded and welded; The second telescopic arm 2042, the first telescopic arm 2041, and the supporting arm 203 are retracted in sequence; The mounting seat 201 is rotated to make the hanger mechanism 20 face the direction of the main line 40, and the welding device 30 is retracted to prepare for entering the next rail welding location.

[0057] The operation method provided in this embodiment sets the operation of the cross-line rail welding equipment 1 and the rail welding operation on different track lines. During the rail welding operation, there is no need to install temporary joints and rail buckle accessories. The cross-line rail welding equipment 1 can complete the rail welding across the line, reducing the number of installation and removal of temporary joints, rail buckle accessories and rollers, thereby improving construction efficiency.

[0058] At present, the rail replacement construction of the operating railway is carried out based on the main line, that is, the operation of the engineering train and the rail replacement operation are all carried out on one railway line. The new long rail 5 is unloaded by "road unloading method". The long rail is dragged out from the long rail conveyor. When the rear end of the rail enters the on-board fixed flash welder, the long rail train stops, and the traction device is used to drag another pair of long rails from the long rail conveyor. The on-board fixed flash welder is used to weld the first pair of rails and the second pair of rails into a longer length to form a new long rail 5. The front end of the new long rail 5 is placed on the outside of the running track rail, and the existing long rail is pulled out of the bearing rail groove by the rail replacement trolley and placed on the inside of the railway line rail. At the same time, the new long rail 5 is pulled into the bearing rail groove to complete the replacement of the old and new long rails; the train is reversed and the rail replacement trolley is used to shovel and recycle the rail to be replaced. In the future, the welding of rail unit joints, stress release and locking, and welding of rail locking joints will continue until all processes are completed.

[0059] The various procedures of track replacement construction are carried out alternately on the railway line in the track replacement section, involving the investment of a large amount of equipment and personnel, making the construction organization difficult; railway equipment vehicles run on railway lines with incomplete fasteners, posing a high safety risk; the various procedures are carried out step by step and cannot be carried out simultaneously, resulting in low construction efficiency.

[0060] The present invention also provides a construction method, based on the above rail laying device, comprising the following steps: The long rail train set 2 arrives at the rail-changing starting point via the main line 40, and the rail welding machine set 3 arrives at both ends of the rail-changing operation section via the adjacent line; Specifically, the long rail train set 2 travels on the main line 40, and the long rail train set 2 reaches the track changing starting point of the track changing operation section via the main line 40. The rail welding unit 3 travels on the adjacent line 50, and the rail welding unit 3 reaches the two ends of the track changing operation section via the adjacent line 50. Neither the long rail train set 2 nor the rail welding unit 3 needs to travel in the track changing operation section of the adjacent line 50, and the driving process is safer.

[0061] The long rail train set 2 recovers the long rail 4 to be replaced on the adjacent line 50 during the process from the rail replacement starting point to the rail replacement end point, and lays a new long rail 5 on the adjacent line 50; Specifically, the long rail train set 2 travels on the rail changing operation section on the main line 40. During the travel, the long rail 4 to be replaced on the adjacent line 50 is recovered by the front end of the long rail train set 2, and a new long rail 5 is laid on the adjacent line 50 by the rear end of the long rail train set 2. When the long rail train set 2 travels from the rail changing starting point to the rail changing end point, the long rail train has completed the process of recovering the long rail 4 to be replaced on the adjacent line 50 and laying the new long rail 5, and the construction efficiency is higher.

[0062] The rail welding unit 3 welds the two ends of the new long rail 5 to the existing rail 6 .

[0063] Specifically, after the laying process of the new long rail 5 is completed, the rail welding unit 3 welds the two ends of the new long rail 5 on the adjacent line 50 to the existing rail 6. The welding work at both ends of the new long rail 5 can be carried out simultaneously to improve the efficiency of the rail replacement construction.

[0064] The construction method based on the rail replacing device provided by the embodiment of the present invention can give full play to the dual-channel advantage of the double-track railway of the own and adjacent lines, with one line for driving and one line for operation, and each process is operated synchronously, which reduces the interference of alternating processes, improves the efficiency of track replacement construction, reduces the risk of driving safety, and can give full play to the effectiveness of the invested equipment.

[0065] Furthermore, as one specific implementation method, the long rail train set 2 in the embodiment of the present invention recovers the long rail 4 to be replaced on the adjacent line during the driving process, including the following steps: The front end of the first cross-line rail-changing vehicle 22 reaches the rail-changing starting point, and the end of the long steel rail 4 to be replaced is lifted by the first cross-line rail-changing vehicle 22. When the first tractor 21 moves forward, the long steel rail 4 to be replaced passes through the rail-pulling device and the first pusher 23 and enters the rail transport vehicle until the end of the long steel rail 4 to be replaced reaches the rear end of the rail transport vehicle. Specifically, the long rail train set 2 includes a first traction vehicle 21, a first cross-line rail changing vehicle 22, a first push vehicle 23, a rail transport vehicle 24, a second push vehicle 25 and a second cross-line rail changing vehicle 26 which are arranged in sequence. Among them, the first traction vehicle 21 is mainly used to provide power for the long rail train set 2, the first cross-line rail changing vehicle 22, the first pushing vehicle 23 and the rail transport vehicle 24 are used to recover the long rail 4 to be replaced located on the adjacent line 50, and the process of recovering the long rail 4 to be replaced is: the front end of the first cross-line rail changing vehicle 22 reaches the rail changing starting point, that is, the first cross-line rail changing vehicle 22 is aligned with the existing rail 6 at the rail changing starting point on the adjacent line 50, the first cross-line rail changing vehicle 22 lifts the end of the long rail 4 to be replaced, the first traction vehicle 21 drives the long rail train set 2 to continue to move toward the direction of the rail changing end point, so that the rear end of the long rail 4 to be replaced passes through the rail derailing device located on the first cross-line rail changing vehicle 22, the long rail train set 2 continues to move, and the long rail 4 to be replaced enters the rail transport vehicle 24 via the first pushing vehicle 23 until the end of the long rail 4 to be replaced reaches the rear end of the rail transport vehicle 24.

[0066] The first tractor 21 stops and cuts off the long rail 4 to be replaced; When the end of the long rail 4 to be replaced reaches the rear end of the rail transport vehicle 24, in order to transport the long rail 4 to be replaced, the long rail train set 2 stops running, cuts off the long rail 4 to be replaced, and completes the recovery of the long rail unit.

[0067] The first tractor 21 continues driving until all the long rails 4 to be replaced are recovered.

[0068] The long rail train set 2 continues to travel, and the long rails 4 to be replaced are continuously recovered, and the recovered rails to be replaced are cut into the length of the long rail conveyor vehicle until the long rails 4 to be replaced are completely recovered.

[0069] Furthermore, as a more specific implementation method, the laying of the new long rail 5 on the adjacent line 50 in the embodiment of the present invention specifically includes the following steps: The rear end of the second cross-line rail-changing vehicle 26 reaches the rail-changing starting point, the first tractor 21 stops, and the new long rail 5 is dragged out from the rail transport vehicle 24 by the second pusher 25, and the new long rail 5 is sequentially passed through the second pusher 25, and the new long rail 5 is pushed into the adjacent line 50 by the rail-pushing device on the second cross-line rail-changing vehicle 26; The second pushing car 25 and the second cross-line rail-changing car 26 are used for laying new long rails 5 on the adjacent line 50. The new long rails 5 are arranged on the rail transport car 24. The second pushing car 25 is used for dragging the new long rails 5 from the rail transport car 24. The second cross-line rail-changing car 26 is used for laying the new long rails 5 in the rail-changing operation section of the adjacent line 50. The specific process is as follows: when the long rail train set 2 travels to the rear end of the second cross-line rail-changing car 26 and reaches the rail-changing starting point, the long rail train set 2 stops, and the new long rails 5 in the rail transport car 24 are dragged out by the second pushing car 25. The new long rails 5 are sequentially transported to the second cross-line rail-changing car 26 through the second pushing car 25. The new long rails 5 are dialed into the rail-changing operation section on the adjacent line 50 by the rail-shifting device, and the end of the new long rail 5 reaches the rail-changing starting point.

[0070] Align and fix the end of the new long rail 5 with the existing rail 6; The end of the new long rail 5 is aligned with the existing rail 6, and the two are fixed by the staff.

[0071] The first tractor 21 continues to move until the laying of the new long rail 5 is completed.

[0072] The long rail train continues to move, and the new long rail 5 is continuously pulled out until the laying of the new long rail 5 is completed.

[0073] In this embodiment, the recovery of the long rails 4 to be replaced and the laying of new long rails 5 are two interrelated processes. The recovery of the long rails 4 to be replaced is completed by the front end of the long rail train set 2, and the laying of the new long rails 5 is completed by the rear end of the long rail train set 2. These processes are completed simultaneously during the forward movement of the long rail train set 2, and the work efficiency is higher.

[0074] Furthermore, as one of the specific implementation methods, the rail welding unit 3 welds the two ends of the new long rail 5 to the existing rail 6, which specifically includes the following steps: welding the rear end of the new long rail 5 located at the starting point of the rail change to the existing rail 6 through the first rail welding group 31, and welding the front end of the new long rail 5 located at the end point of the rail change to the existing rail 6 through the second rail welding group 32.

[0075] By providing the first welding rail group 31 and the second welding rail group 32, both ends of the new long rail 5 are welded without driving in the rail replacement construction section, which is safer and can improve work efficiency.

[0076] The construction equipment in this embodiment is configured as a dual-machine configuration to meet the safety requirements of operating railways. At the same time, all equipment participates in the operation to give full play to the equipment efficiency.

[0077] In the above structure, as one of the specific implementation methods, the new long rail 5 in the embodiment of the present invention includes at least two long rail units. The long rail units are placed in sequence from the starting point to the end point of the rail change. The long rail units close to the starting point and the end point of the rail change are welded by the rail welding unit 3, and the adjacent long rail units are welded by the cross-line rail welding equipment. The cross-line rail welding equipment is arranged at the rear end of the long rail train group 2, and the cross-line rail welding equipment welds the adjacent long rail units on the adjacent line 50 via the main line 40.

[0078] In the above structure, as one implementation mode, at least two cross-line welding rail devices are provided in the embodiment of the present invention.

[0079] The long rail units are laid on the adjacent line 50 in sequence by the second pusher 25 and the second cross-line rail-changing vehicle 26. After at least two long rail units are laid, the cross-line rail welding equipment is used to weld the joints of the two adjacent long rail units. The cross-line rail welding equipment travels on the main line 40 and does not need to travel on the rail-changing construction section on the adjacent line 50, making the working process safer.

[0080] As one specific implementation method, the new long rail 5 in the embodiment of the present invention includes three long rail units. When the first long rail unit 51 is laid, the first welding rail group 31 is used to connect the rear end of the first long rail unit 51 with the existing rail 6; when the second long rail unit 52 is laid, the second cross-line welding rail equipment is used to carry out the long rail unit welding operation to connect the first long rail unit 51 with the second long rail unit 52; After the welding of the third long rail unit 53 is completed, the first cross-line rail welding equipment is used to connect the second long rail unit 52 and the third long rail unit 53. After the rail unit is welded, the stress of the newly laid long rail is relieved and locked, and the front end of the third long rail unit 53 is connected to the existing rail 6 through the second welding rail group 32.

[0081] After completing the planned rail replacement task, we started equipment preparation and restoration, site cleaning, line inspection and other work to ensure that the conditions for opening are met and the line is restored to service.
