Description

Technical Field

[0001] The present application relates to the field of railway engineering operations, and in particular to a continuous sleeper changing operation train and operation method. Background Art

[0002] Railway sleeper replacement is a key task in mechanized railway line maintenance. With the continuous advancement of engineering technology, sleeper replacement has evolved from a traditional, fully manual operation to one using small and large-scale machinery. This has shortened sleeper replacement time, reduced the workload of construction workers, reduced staffing, and facilitated management.

[0003] At present, there are two main methods of using small machines to replace sleepers: first, using small machines in conjunction with track lifting equipment to move the sleepers out from the side of the track and perform side-pull replacement; second, using a dual-purpose road-rail excavator in conjunction with a sleeper clamp for construction. Both of these solutions require that the new sleepers be transported to both sides of the track where the sleepers are to be replaced in advance and placed there. After the replacement is complete, the old sleepers placed on both sides of the track need to be transported away. On the one hand, this requires a large space on both sides of the track, and on the other hand, it requires multiple transportation processes. Moreover, after the sleepers are replaced, the fasteners need to be manually fastened, which requires a large amount of manual work, and the steps are cumbersome and inefficient. In addition, in the existing technology, railway sleeper replacement generally does not process the sleeper bottom bed, and the construction quality is not high. Therefore, there is a need for subsequent steps to process the sleeper bed, resulting in more processes and poor continuity, which in turn causes the entire sleeper replacement process to last longer, greatly affecting the normal operation of the railway.

[0004] Using large-scale track maintenance machinery to replace sleepers is done on overhaul trains. This requires cutting the track, and sleeper and track replacement are typically performed simultaneously, resulting in low efficiency. This requires cutting the track, and then welding the track back to a seamless line after completion, increasing both construction steps and maintenance costs.

[0005] In view of this, this application is hereby filed. Summary of the Invention

Figures 1 to 7 As shown in the figures, the present embodiment provides a continuous sleeper replacement operation train and operation method for removing old sleepers and installing new sleepers on a railway.

[0031] The continuous sleeper changing operation train provided by the embodiment of the application is used for continuously changing sleepers on a railway. A direction extending along a track is defined as a longitudinal direction, a direction perpendicular to the track is defined as a transverse direction, and a front direction is a direction in which the train travels. The train comprises a ballast treatment vehicle B and a sleeper changing operation vehicle C connected to each other. The ballast treatment vehicle B is provided with a ballast treatment device. The ballast treatment device is used for excavating ballast on both sides of the track, transferring the ballast between sleepers to both sides of the track, and backfilling the ballast to an inner side of the track after the sleeper changing operation vehicle completes the sleeper changing operation. The sleeper changing operation vehicle C is used for recovering old sleepers and laying new sleepers.

[0032] As an embodiment of the application, the ballast treatment device comprises a side slope excavating device 11 and a sleeper interval ballast treatment device 10. The sleeper interval ballast treatment device 10 is connected to a lower side of the ballast treatment vehicle B and is used for excavating the ballast between sleepers and transferring the ballast to both sides of the track. The side slope excavating device 11 is used for excavating the ballast on both sides of the track and transferring the ballast to a ballast conveying platform 13, and the ballast is transported to a backfilling position by the ballast conveying platform 13.

[0033] As an embodiment of the application, the ballast treatment device further comprises the ballast conveying platform 13. The ballast conveying platform 13 is installed on an upper side of the ballast treatment vehicle B, one end of the ballast conveying platform 13 is connected to the side slope excavating device 11, and the ballast excavated and conveyed by the side slope excavating device 11 is received by the ballast conveying platform 13. The other end of the ballast conveying platform 13 extends to a ballast backfilling position of the sleeper changing operation vehicle C.

[0034] In the implementation, the side slope excavating device 11 is symmetrically installed on both sides of the ballast treatment vehicle B and is arranged on both sides of the operation train relative to an axis of the forward direction. A rotation point is arranged on the side slope excavating device 11, and the rotation point is used for switching between a working position and a high-speed walking position through angle adjustment. The side slope excavating device 11 used for excavating the ballast on both sides of the track can have many structures, for example, a bucket. The ballast excavated by the side slope excavating device 11 can be conveyed to an end of the ballast conveying platform 13 by a screw conveyor. As a specific embodiment, the ballast conveying platform 13 is a conveying belt.

[0035] As an embodiment of the application, the ballast on both sides of the track is excavated by the side slope excavating device 11 and is transported to the ballast conveying platform 13 at an upper end. Then, the ballast is backfilled to an inner side of the track by the ballast conveying platform 13. A ballast storage device can be further installed at an end of the ballast conveying platform 13 and is used for controlling a backfilling speed of the ballast.

[0036] During implementation, the ballast-processing device 10 between sleepers transfers the ballast on the inner side of the ballast track between sleepers to the outer side of the track to fill the ballast on the slope. The ballast-processing device 10 between sleepers performs step-by-step operation when the entire vehicle is continuously moving forward; that is, it is stationary during the ballast transfer and moves to the next work station after the ballast transfer is completed; thus, the ballast-processing device 10 between sleepers is movably connected to the vehicle frame. In specific implementation, a variety of structures can realize the ballast between sleepers being pushed to both sides of the track. For example, a ballast scraper is connected to a movable frame, and the ballast scraper is driven by a hydraulic cylinder to guide the ballast scraper along the frame to push the ballast between sleepers to both sides of the track; a small bucket is connected to a multi-joint robotic arm, and the ballast between sleepers is removed by the small bucket under power drive and pushed to both sides of the track by the multi-joint robotic arm; the ballast between sleepers is directly excavated to the outside of the track by a knife plate excavation device.

[0037] As an embodiment of the present application, the continuous sleeper replacement operation train also includes a sleeper transport vehicle A and a power vehicle D, which are used to store and transport new sleepers and old sleepers; the power vehicle D is used to provide power for the operation train.

[0038] During implementation, the new sleeper 1 is directly transported to the site by the sleeper transport vehicle A, and the old sleeper 4 is driven away from the site by the sleeper transport vehicle, which saves the time of laying the new sleeper 1 on both sides of the track in advance and the time of picking up and transporting the old sleeper 4. The sleeper can be replaced without sawing the track, and the integrated continuous operation of fastener disassembly, sleeper replacement, fastener installation and sleeper transportation is achieved at one window point, saving a lot of construction time.

[0039] As an embodiment of the present application, the sleeper transport vehicle A, the ballast processing vehicle B, the sleeper changing vehicle C and the power vehicle D are arranged and connected in sequence backward along the direction of travel.

[0040] like Figure 2 As shown, as an embodiment of the present application, the sleeper transport vehicle A includes multiple flatbed trucks 2 and a gantry crane 3, and the multiple flatbed trucks 2 are connected in sequence front and back to carry new sleepers 1 and old sleepers 4; each flatbed truck 2 is provided with a sliding track, and a track crossing device is provided between each flatbed truck 2, and the track crossing device is used to connect the sliding tracks on two adjacent flatbed trucks 2; the gantry crane 3 travels along the sliding track and the track crossing device between each flatbed truck 2, and has a large range of movement; a sleeper clamping device is provided on the gantry crane 3, and the sleeper device can move up and down to clamp the sleepers, and the storage and transportation of the new sleepers 1 and the old sleepers 4 are realized through the sleeper transport vehicle A.

[0041] In practice, the method for clamping the sleeper is conventional, and the clamping device can also take many forms, such as clamps and manipulators. As an embodiment, the gantry crane 3 can also be equipped with a vertical drive device, which controls the vertical movement of the sleeper clamping device to clamp the sleeper. The vertical drive device can be a drive cylinder or a drive motor, or other structure capable of driving the sleeper clamping device to move up and down. To prevent the gantry crane 3 from running out of control, a buffer stop is provided at the front end of the sleeper transport vehicle A.

[0042] As an embodiment, the sliding tracks on each flatbed truck 2 and the track crossing devices between each flatbed truck 2 enable the gantry crane 3 to move between the flatbed trucks 2. The gantry crane 3 is equipped with a power system, so that the gantry crane 3 can move over a large range of flatbed trucks 2 and move independently.

[0043] Through the embodiment of the present application, the new sleepers 1 are directly transported to the site by the sleeper transport vehicle A, and the old sleepers 4 are driven away from the site by the sleeper transport vehicle A, which saves the time of placing the new sleepers 1 on both sides of the track in advance and the time of picking up and transporting the old sleepers 4.

[0044] As a specific embodiment of the present application, the sleeper conveying platform is installed parallel to the top of the working train and extends along the direction of travel; it is arranged between the sleeper changing operation vehicle C, the ballast processing vehicle B and the sleeper transport vehicle A, and is used to convey the dismantled old sleepers 4 to the sleeper transport vehicle A, and at the same time convey the new sleepers 1 conveyed by the sleeper transport vehicle A to the target placement position of the new sleepers 1.

[0045] like Figures 2-3 As shown, as an embodiment, the sleeper conveying platform includes an old sleeper conveying platform 6, an old sleeper rotating device 7, a new sleeper conveying platform 5 and a new sleeper rotating device 9. The old sleeper conveying platforms 6 are connected in sequence and arranged in multiples; they extend from the sleeper changing operation vehicle C to the sleeper transport vehicle A to transport the old sleepers 4 forward along the travel direction; an old sleeper rotating device 7 is installed between the old sleeper conveying platforms 6, and the old sleeper rotating device 7 is located above the ballast processing device and is used to rotate the old sleepers 4 on the old sleeper conveying platform 90° before transportation; before rotation, the length direction of the old sleeper 4 is perpendicular to the travel direction, and after rotation, the length direction of the old sleeper 4 is parallel to the travel direction; the new sleeper conveying platforms 5 are connected in sequence and arranged in multiples, extending from the sleeper changing operation vehicle to the sleeper transport vehicle; a new sleeper rotating device 9 is installed between the new sleeper conveying platforms 5, and the new sleeper rotating device 9 is located in the ballast processing device. The new sleeper rotating device 9 transports the new sleeper 1 backward along the travel direction, and before rotation, the length direction of the new sleeper 1 is perpendicular to the travel direction, and after rotation, the length direction of the new sleeper 1 is parallel to the travel direction. The transmission of the new sleeper 1 and the old sleeper 4 can also be replaced by a sleeper transport vehicle with a sleeper transfer device.

[0046] As a specific embodiment, the new sleeper conveying platform 5 and the old sleeper conveying platform 6 can be conveyed by a conveying belt or a chain wheel.

[0047] In the implementation, the old sleeper rotating device 7 and the new sleeper rotating device 9 for realizing the rotating function can have various structures and forms; for example, a clamp or a mechanical hand for clamping sleepers can be installed on a rotating base, or a conveying belt and a conveying motor can be installed on the rotating base, the conveying motor drives the conveying belt to realize the conveying of sleepers, and the rotating base rotates under the driving of a driving mechanism to realize the change of direction.

[0048] As an embodiment of the present application, the sleeper changing vehicle C is further provided with a sleeper converging device 17, two old sleeper pickup devices and a transfer platform 18; the sleeper converging device 17 is used for converging multiple old sleepers 4 into an old sleeper group; the sleeper converging device 17 converges multiple old sleepers 4 into an old sleeper group, so that the old sleeper pickup device can pick up sleepers, work time is saved, and work efficiency is improved.

[0049] The old sleeper pickup device is arranged at the bottom of the sleeper changing vehicle C and includes a first old sleeper pickup device 19 and a second old sleeper pickup device 20; the first old sleeper pickup device 19 is used for clamping the converged old sleeper group from the sleeper converging device 17, rotating the old sleeper group by 90° and placing the old sleeper group on the transfer platform 18; then the second old sleeper pickup device 20 transfers the old sleeper group on the transfer platform 18 to the old sleeper conveying platform 6. Then the old sleeper conveying platform 6 transports the old sleeper group to the sleeper transporting vehicle A; the sleepers on the transfer platform 18 are in a longitudinal direction, and the sleepers at the front end of the old sleeper conveying platform 6 are in a transverse direction, so that the old sleeper rotating device 7 is arranged on the old sleeper conveying platform 6.

[0050] It is worth noting that the old sleeper pickup device is divided into two in the embodiment of the present application to speed up the work efficiency, and the old sleeper pickup can also be realized by one device.

[0051] As a specific embodiment of the present application, the sleeper converging device 17 of the sleeper changing vehicle C is located in front of the first old sleeper pickup device 19 and converges multiple old sleepers 4 into an old sleeper group; the sleeper converging device 17 can adopt, for example, Figure 7The structure shown, including the fixed rod 1703, the sleeper pushing rod 1701 and the sleeper oil cylinder 1702, forms a triangular structure; the fixed rod 1703 is rotationally connected with the sleeper pushing rod 1701, the base of the sleeper oil cylinder 1702 is rotationally connected with the fixed rod 1703, the piston rod of the sleeper oil cylinder 1702 is rotationally connected with the end of the sleeper pushing rod 1701, and the sleeper oil cylinder 1702 is contracted to lift the sleeper pushing rod 1701; the sleeper oil cylinder 1702 is extended to lower the sleeper pushing rod 1701, and the sleeper closing device 17 is movably connected with the frame of the sleeper changing vehicle C, and can move longitudinally along the sleeper changing vehicle C to realize the closing of the disassembled old sleepers 4.

[0052] It should be noted that the sleeper closing device 1 can also be completed by a sleeper closing structure with a higher degree of automation.

[0053] As a specific embodiment of the present application, the old sleeper picking device is connected with the frame of the sleeper changing vehicle C, and the bottom of the sleeper changing vehicle C can move relative to the sleeper changing vehicle C to clamp and rotate the closed old sleeper group. In the implementation, after the rail lifting device 16 lifts the rail, the first old sleeper picking device 19 takes out the old sleeper group and rotates the old sleeper group by 90° to place it on the transfer platform 18; the second old sleeper picking device 20 rotates the old sleeper group on the transfer platform 18 and transfers it to the old sleeper conveying platform 6, and then transfers it to the sleeper transport vehicle A from the old sleeper conveying platform 6.

[0054] As an embodiment of the present application, the new sleeper placing device is also installed on the sleeper changing vehicle C. In the implementation, the new sleeper placing device is adjacent to the end of the new sleeper conveying platform 5, is used to clamp the new sleeper 1 conveyed by the new sleeper conveying platform 5, and rotate the new sleeper 1 by 90° to place it at the target placement position; the new sleeper first placing device 21 clamps the new sleeper group at the end of the new sleeper conveying platform 5 and places it on the ballast bed, and the new sleeper second placing device 22 rotates the new sleeper group by 90° to adjust the sleeper-to-sleeper distance and place it at the appropriate position. Specifically, in order to enable the sleepers to smoothly fall into the inside of the rail, the sleepers at the tail end of the new sleeper conveying platform 5 are in the longitudinal direction, and the sleepers at the front end of the new sleeper conveying platform 5 are in the transverse direction, so the new sleeper rotating device 9 is arranged on the new sleeper conveying platform 5.

[0055] It should be noted that the new sleeper placing device is divided into two in the embodiment of the present application in order to speed up the work efficiency, and the new sleeper placing can also be realized by one device.

[0056] After the horizontal and longitudinal positions of the new sleepers are adjusted, the ballast between the sleepers is backfilled. The ballast is directly backfilled to the inside of the rail through the ballast conveying platform 13.

[0057] As an embodiment of the present application, the tie treatment vehicle B is further provided with a fastener dismounting and collecting device, which is used for dismounting, collecting and storing the fasteners on the old sleepers. The fastener dismounting and collecting device on the tie treatment vehicle B includes a fastener dismounting device 12 and a fastener collecting device 14. The fastener dismounting device 12 is connected below the tie treatment vehicle B and can dismount the fasteners of multiple sleepers at one time, and then places the fasteners on both sides of the track. The fastener dismounting device 12 is movably connected to the frame of the tie treatment vehicle B. The fastener dismounting device 12 can be implemented by various structures, for example, not only an internal combustion wrench or an electric wrench can be used, but also a known dismounting device can be used to dismount the fasteners on the sleepers. The fastener collecting device 14 is provided with a magnetic device and a storage device. The magnetic device collects the dismounted fasteners, and the storage device is used for storing the dismounted fasteners. That is, the fastener dismounting device 12 places the dismounted fasteners on both sides of the track, and then the magnetic device collects the dismounted fasteners and stores them in the storage device.

[0058] It should be particularly pointed out that the fastener dismounting device 12 and the fastener collecting device 14 can all use fully automatic dismounting and collecting devices with higher automation, or manual or small machines can be used to dismount or install the fasteners.
