Description

Technical Field

[0001] The present application relates to the field of rail transit maintenance, and more specifically, to a rail transport vehicle set and an operating method thereof. Background Art

[0002] With the development of the domestic economy and the increase in population, the demand for rail transit is getting higher and higher. The construction of rail transit in my country and even in the world is accelerating, and the operating mileage of rail transit is constantly increasing. The main fixed facilities of rail transit include rail lines. During operation, rail lines often have problems such as wear and corrosion of rails. In order to ensure the stability and safety of train operation, when the rails reach their service life, they need to be replaced.

[0003] At present, the construction of track replacement in China generally involves transporting 25m long new rails (short rails) to the replacement area, placing them in order in the middle of the track bed or on the side of the ditch, and tying them with iron wire to prevent them from affecting driving. Then the short rails are welded together on site, and the flaw detection and fine grinding of the rail joints are completed. After that, the old rails are sawed off, the short rails are welded into long rails, and the new and old long rails are replaced by cranes. Clamps are installed at both ends of the new long rails for temporary connection, the line is locked, and the track is repaired to meet operating conditions. Finally, the rail joints at both ends are welded, and the replaced old rails are cut into 25m lengths for recycling. This construction method needs to be carried out after the relevant lines are shut down and the power supply system is shut down. It usually takes 3 to 4 hours, with a large workload and a large number of construction personnel, and has great safety hazards.

[0004] In order to solve this problem, some lines currently weld short rails into long rails in the factory, and then use long rail transport vehicles to directly transport them to the site for construction. This can save a lot of construction time, and the short rails are welded in the factory, so the welding quality is better.

[0005] Existing long rail transport vehicles can be roughly divided into two categories. One category is a long rail transport vehicle that adopts longitudinal rail collection and unloading, represented by a rail transport vehicle set CN110924246A. This type of long rail transport vehicle is equipped with a rail collection and changing device with a mechanical arm that moves on the rail transport vehicle. This type of long rail transport vehicle can realize the transportation and collection and unloading of long rails in tunnels and small radius curves, is not greatly affected by construction and line conditions, and can realize one-way out-of-position collection and unloading of rails. However, this type of long rail transport vehicle is affected by the structure and the construction organization is relatively simple. The rail collection and unloading device moves on the long rail transport vehicle, and the long rail transport vehicle needs to be arranged with a track for the rail collection and unloading device to operate, and a bridge device needs to be arranged between adjacent vehicles for the rail collection and unloading device to pass through, but the bridge device has poor connection smoothness with the front and rear vehicles in the small curve section, and there are safety hazards in the operation of the rail collection and changing device on the long rail transport vehicle.

[0006] The other type is a long rail transport vehicle that uses the same-side transverse collection and unloading of rails, represented by a rail transport vehicle set CN214874786U. This type of long rail transport vehicle is formed by connecting multiple rail hoisting devices and rail bearing device flatbed cars. This type of long rail transport vehicle can be reconnected through the hoisting device, and can synchronously lift and laterally move the rails from both sides of the train to achieve the collection and unloading of long rails. However, this type of long rail transport vehicle can only realize the collection and unloading of long rails on the same side, and cannot perform out-of-position collection and unloading of rails. In addition, this type of long rail transport vehicle is greatly affected by the construction environment and the line, and cannot adapt well to the narrow space of the tunnel and the smaller curve radius. If the line that needs to replace the rails is a subway line, this type of rail transport vehicle set is difficult to work. Summary of the invention

[0041] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0042] In the process of realizing the present application, the inventor discovered that in the existing rail-changing operation using long rail transport vehicles, the long rail transport vehicles that longitudinally collect and unload rails are operated by rail collection and changing devices with mechanical arms that can move on the rail transport vehicles. Affected by the structure, the construction organization is relatively simple, and the long rail transport vehicles need to be arranged with tracks and bridge devices for the operation of the rail collection and unloading devices. Since the smoothness of the connection between the bridge device and the front and rear vehicles in the small curve section is poor, there are safety hazards in the operation of the rail collection and changing devices on the long rail transport vehicles. The long rail transport vehicles that collect and unload rails horizontally on the same side can only collect and unload long rails on the same side, and cannot collect and unload rails in different positions. Moreover, they are greatly affected by the construction environment and the line, and cannot adapt well to the narrow space of the tunnel and the small curve radius. If the line that needs to replace the rails is a subway line, it is difficult to work.

[0043] In response to the above problems, an embodiment of the present application provides a long rail transport vehicle group, which is assembled by connecting multiple functional vehicles. It is easy to assemble and disassemble and can be flexibly combined according to construction needs. It can collect and unload rails longitudinally and transversely. There is no need to arrange tracks and bridge devices for the operation of rail collection and unloading devices on the transport vehicle group. It is less affected by the construction environment and line lines, and can adapt well to the narrow space of tunnels and smaller curve radius.

[0044] In order to clearly explain the present application, in the specific embodiment of the present application, the direction extending along the rail is defined as the longitudinal direction, the direction extending along the sleeper is defined as the transverse direction, the direction perpendicular to the plane where the transverse direction and the longitudinal direction are located is defined as the vertical direction, and the forward direction of the whole vehicle set is defined as the forward direction. No matter which car at the two ends of the whole vehicle set is used as the lead car, the forward direction of the whole vehicle set is defined as the forward direction. Figure 1 As shown, when the whole vehicle set is running with the first safety car 600 as the leading car, the direction of the first safety car 600 is forward, that is, at this time the first safety car 600 is in front and the rail unloading car 100 is behind; when the whole vehicle set is running with the rail unloading car 100 as the leading car, the direction of the rail unloading car 100 is forward, that is, at this time the rail unloading car 100 is in front and the first safety car 600 is behind.

[0045] Figure 1 The front view of the rail transport vehicle set provided in the embodiment of the present application is as follows: Figure 1The rail transport vehicle group shown includes a rail unloading vehicle 100, a transition vehicle 200, a safety vehicle, a rail transport vehicle 400 and a rail locking vehicle 500, wherein the rail unloading vehicle 100 is located at one end of the rail transport group, and the safety vehicle, the rail transport vehicle 400, the rail locking vehicle 500, the transition vehicle 200 and the rail unloading vehicle 100 are detachably connected in a row. The number and arrangement order of the safety vehicle, the rail locking vehicle 500 and the rail transport vehicle 400 can be flexibly combined and respectively used for collecting and unloading rails of different lengths. For example, the rail transport vehicle and the rail locking vehicle can be combined to transport 25m short rails. In addition, the safety vehicle and the rail transport vehicle can be combined, the safety vehicle and the rail locking vehicle can be combined, the safety vehicle and the safety vehicle can be combined, and the rail transport vehicle and the rail transport vehicle can be combined.

[0046] The embodiment of the present application provides a functional vehicle combination method for a rail transport vehicle group used for long rail disassembly transportation, such as Figure 1 As shown, there are two safety vehicles, including a first safety vehicle 600 and a second safety vehicle 300, and at least two rail transport vehicles 400. In one specific embodiment, there are five rail transport vehicles 400. The first safety vehicle 600 is located at one end of the rail transport vehicle group, and the unloading vehicle 100 is located at the other end of the rail transport vehicle group. From the unloading vehicle 100 to the direction of the first safety vehicle 600, the unloading vehicle 100, the transition vehicle 200, and the second safety vehicle 300 are connected in sequence. A locking vehicle 500 is arranged between the second safety vehicle 300 and the first safety vehicle 600, two rail transport vehicles 400 are arranged between the locking vehicle 500 and the first safety vehicle 600, and three rail transport vehicles 400 are arranged between the locking vehicle 500 and the second safety vehicle 300. The functional vehicles are connected in sequence through detachable couplers to form a rail transport vehicle set in the order of rail unloading vehicle 100, transition vehicle 200, second safety vehicle 300, rail transport vehicle 400, rail locking vehicle 500, rail transport vehicle 400 and first safety vehicle 600.

[0047] Furthermore, the first safety vehicle 600, the rail transport vehicle 400 and the rail locking vehicle 500 are all provided with a rail lifting device 510. The rail lifting device 510 can be an L-shaped electric lift, which is used when the rails are horizontally collected. In some specific embodiments, the first safety vehicle is also provided with a towing device 131.

[0048] The longitudinal rail unloading function of the above-mentioned rail transport vehicle set is mainly realized by the rail unloading vehicle 100. The rail unloading vehicle 100 is provided with a device that can be used for longitudinal rail unloading. The embodiment of the present application provides a specific implementation method of the longitudinal rail unloading device. Fig.12 A front view of the auxiliary vehicle provided in the embodiment of the present application; Fig.13 A top view of the auxiliary vehicle provided in the embodiment of the present application, such as Figure 1 , Fig.12 and Fig.13As shown, an auxiliary trolley 130 and a lifting device for retracting and releasing the auxiliary trolley 130 are provided under the frame of the rail unloading vehicle 100, an auxiliary trolley locking device for fixedly connecting the auxiliary trolley 130 to the rail unloading vehicle 100 is provided at the rear of the rail unloading vehicle 100, and a towing device 131 for towing the rails and an auxiliary trolley rail guide device 132 for guiding the rails passing through the auxiliary trolley are provided on the auxiliary trolley 130. For example, the towing device 131 can adopt a winch. When working, the wire rope of the winch is fixed to one end of the rail by a clamp. When the winch is operated, the rail can be towed to move. The auxiliary trolley rail guide device 132 should preferably adopt structures such as slide rails and pulleys to limit the lateral movement of the rails and ensure their longitudinal movement.

[0049] Furthermore, the auxiliary trolley rail guide device 132 includes an auxiliary trolley middle guide device and auxiliary trolley side guide devices, wherein the auxiliary trolley middle guide device is arranged at the longitudinal middle position of the upper surface of the auxiliary trolley 130, and the auxiliary trolley side guide devices are located on both sides of the middle guide device, the middle guide device is used to guide the rail to the roadbed, and the side guide devices are used to guide the new rail to the outer side of the old rail on the roadbed. The auxiliary trolley rail guide device 132 includes two rollers arranged opposite to each other and a roller frame supporting the rollers, the roller frame is fixed on the frame of the auxiliary trolley, and the roller can rotate horizontally in the roller frame. When the train group is working, the rail passes between the two rollers, and the auxiliary trolley rail guide device 132 limits the movement of the rail in the lateral direction, reduces the friction in the longitudinal direction, and guides the rail to move smoothly in the longitudinal direction.

[0050] The embodiment of the present application also provides a specific implementation method of the rail unloading vehicle 100. Figure 2 This is a main view of the rail unloading vehicle provided in the embodiment of the present application. Figure 3 A top view of the rail unloading vehicle provided in the embodiment of the present application, such as Figure 2 and Figure 3 As shown, the rail unloading vehicle 100 is longitudinally provided with a rail guide groove 110 and a rail guide device 120 for providing guidance for the rails passing through the rail unloading vehicle 100 during rail unloading, wherein the rail guide device 120 for the rail unloading vehicle is arranged at the front end of the upper surface of the rail unloading vehicle 100, and the rail guide groove 110 is located at the rear end of the upper surface of the rail unloading vehicle 100.

[0051] Furthermore, the opening width of one end of the rail guide device 120 of the rail unloading vehicle toward the first safety vehicle 600 is greater than the opening width of the other end thereof, so as to facilitate the introduction of the rail into the rear rail guide groove.

[0052] Furthermore, Figure 4 The main view of the transition vehicle provided in the embodiment of the present application, Figure 5 A top view of a transition vehicle provided in an embodiment of the present application, such as Figure 4 and Figure 5As shown, the transition vehicle 200 is provided with a rail shifting device 210, which provides lateral and vertical position adjustment for the rails when the rails are longitudinally collected and unloaded, especially provides greater lateral position adjustment for the rails when the rails are collected and unloaded out of position on one side. The rail shifting device is a prior art means, and its structure and working process can be realized by using existing technologies, which will not be described in detail in this embodiment.

[0053] Furthermore, Figure 6 The second safety car main view provided in the embodiment of the present application is Figure 7 A top view of the second safety car provided in the embodiment of the present application, such as Figure 6 and Figure 7 As shown, a safety door 310 is provided on the safety vehicle. The safety door is mainly composed of a door, a door post and a door support. The two doors of the safety door can be rotated 90° along the door post to complete the switch state transition, and the door support can also be rotated along the bottom shaft to complete the transition from the support position to the laid-down position. The safety door 310 is arranged along the transverse direction of the vehicle body. When the vehicle is carrying rails, the safety door is closed to prevent the rails from longitudinally jumping out of the storage area due to sudden changes in vehicle speed during transportation, such as sudden braking. The setting position of the safety door is designed according to the length of the rails to be transported. In some specific embodiments, the safety door on the safety vehicle is designed to be three, which are used when transporting 100m, 75m and 50m rails respectively. The safety door in use is in the support position, and the safety door not in use is in the open position. Fig.14 The first safety car main view provided in the embodiment of the present application is Fig.15 The top view of the first safety car provided in the embodiment of the present application, in some specific embodiments, the first safety car is also provided with a towing device 131. The towing device 131 on the first safety car can be a winch, and when performing the rail collection operation, the tail end of the rail is recovered to the rail unloading car, and the towing device is used to pull the tail end of the rail to the second safety car.

[0054] Furthermore, Fig.10 This is a main view of the track locking vehicle provided in the embodiment of the present application. Fig.11 A top view of a rail locking vehicle provided in an embodiment of the present application, such as Fig.10 and Fig.11 As shown, the rail locking vehicle 500 is provided with a rail locking device 520, which is used to limit the lateral and longitudinal movement of the rails carried on the long rail transport vehicle set.

[0055] Furthermore, Figure 8 The main view of the rail transport vehicle provided in the embodiment of the present application, Fig. 9 A top view of the rail transport vehicle provided in the embodiment of the present application, such as Figures 6 to 11As shown, the safety vehicle, the rail transport vehicle 400 and the rail locking vehicle 500 are all provided with a rail roller frame 320 with a plurality of rollers. The rail roller frame 320 is used to carry the rails and change the longitudinal movement of the rails from sliding to longitudinal movement by roller rotation, thereby reducing movement resistance.

[0056] The embodiment of the present application also provides an operating method for a rail transport vehicle set, which uses the above rail transport vehicle set to perform longitudinal rail unloading operations, longitudinal rail collecting operations, transverse rail unloading operations, and transverse rail collecting operations.

[0057] like Fig.16 As shown in FIG. 1 , the longitudinal rail unloading operation of the rail transport vehicle group includes the following steps:

[0058] Step 1: Tow the rail transport vehicle group to the working area, release the auxiliary trolley 130, make the auxiliary trolley 130 run to the working position, and connect the rear end of the rail unloading vehicle 100 with the auxiliary trolley 130;

[0059] In step 1, the release of the auxiliary trolley 130 can be performed by manual disassembly or by a lifting or disassembly device. The tail end of the unloading vehicle 100 refers to the idle end of the unloading vehicle 100, and the other end of the unloading vehicle 100 is connected to the transition vehicle 200;

[0060] Step 2: Connect the dragging device 131 on the auxiliary trolley 130 to the rail to be unloaded;

[0061] In step 2, if a winch is used as the towing device 131, the wire rope of the winch is connected to the end of the rail to be removed close to the auxiliary trolley 130. In addition, if a safety door 310 is provided on the safety vehicle and a rail locking device 520 is provided on the rail locking vehicle, before executing step 2, the safety door 310 and the rail locking device 520 need to be opened to allow the rails carried on the rail transport vehicle set to be in a state where they can move freely.

[0062] Step 3: The auxiliary trolley 130 is locked in place, and the dragging device 131 pulls the unloaded rail to move longitudinally, and the unloaded rail gradually separates from the train and enters the auxiliary trolley rail guide device 132 until one end of the unloaded rail contacts the ballast bed;

[0063] Step 4: After fixing the end of the unloaded rail that contacts the ballast bed to the track, release the connection between the dragging device 131 on the auxiliary trolley 130 and the unloaded rail, so that the dragging device 131 is reset;

[0064] Step 5: The locking state of the auxiliary trolley 130 is released, and the entire rail transport train set moves with the first safety car 600 as the leading car, and the auxiliary trolley 130 moves with the rail transport train set until the rails to be unloaded are completely unloaded;

[0065] Step 6: The rail transport vehicle group drives out of the construction area; if the safety vehicle is provided with a safety door 310 and the rail locking device 520 is provided on the rail locking vehicle, before executing step 6, the safety door 310 and the rail locking device 520 need to be closed again.

[0066] Usually, the long rail transport vehicle carries multiple rails, so before executing step 6, steps 1 to 5 need to be repeated until all the carried rails are unloaded.

[0067] like Fig.17 As shown, the longitudinal rail closing of the rail transport vehicle group includes the following steps:

[0068] Step 1: Tow the rail transport vehicle group to the working area, release the auxiliary trolley 130, make the auxiliary trolley 130 run to the working position, and connect the rear end of the rail unloading vehicle 100 with the auxiliary trolley 130;

[0069] Step 2: The rail transport vehicle group runs with the unloading vehicle 100 as the leading vehicle, pushing the auxiliary vehicle 130 to run to the end of the rail to be recovered, and guiding the rail end into the rail guide device 132 of the auxiliary vehicle; if the safety vehicle is provided with a safety door 310, and the rail locking device 520 is provided on the rail locking vehicle, before executing step 2, the safety door 310 and the rail locking device 520 need to be opened, so that the rail to be recovered can smoothly enter the carrying area of ​​the long rail transport vehicle group;

[0070] Step 3: The rail transport vehicle set continues to run with the unloading vehicle 100 as the leading vehicle, and the auxiliary trolley 130 moves with the rail transport vehicle set. The rails to be recovered gradually enter the rail guide device 120 of the unloading vehicle 100 through the auxiliary trolley rail guide device 132, and pass through the unloading vehicle 100 and the transition vehicle 200 with the assistance of the rail guide device 120 and / or manual labor, enter the second safety vehicle 300, the rail transport vehicle 400, and the rail locking vehicle 500, and enter the first safety vehicle 600 under the towing device 131 on the first safety vehicle, until the rails to be recovered are completely retracted onto the rail transport vehicle set;

[0071] Step 4: Recover the auxiliary trolley 130 and drive the vehicle out of the construction area; if the safety vehicle is provided with a safety door 310 and the rail locking device 520 is provided on the rail locking vehicle, before executing step 4, the safety door 310 and the rail locking device 520 need to be closed so that the movement of the rails carried on the rail transport vehicle set is restricted by the rail locking device 520 and the safety door 310 to avoid safety accidents caused by the rails jumping out during transportation.

[0072] like Fig.18 As shown, the transverse unloading of rail transport vehicles includes the following steps:

[0073] Step 1: Pull the rail transport vehicle set to the operation area;

[0074] Step 2: Rotate the rail lifting device 510 on the safety car, rail transport car 400 or rail locking car 500 in the rail transport vehicle group and drop it to the rail to be unloaded. After the rail lifting device 510 is fixedly connected to the rail to be unloaded, control the rail lifting device 510 to drop the rail to be unloaded to both sides of the original track.

[0075] Step 3: The rail transport vehicle drives out of the construction area.

[0076] If the safety vehicle is provided with a safety door 310 and the rail locking device 520 is provided on the rail locking vehicle, before executing step 2, the safety door 310 and the rail locking device 520 need to be opened to facilitate rail unloading; and before executing step 3, the safety door 310 and the rail locking device 520 need to be closed again.

[0077] like Fig.19 As shown, the transverse rail closing of the rail transport vehicle group includes the following steps:

[0078] Step 1: Pull the rail transport vehicle set to the operation area;

[0079] Step 2: Rotate the rail lifting device 510 on the safety car, rail transport car 400 or rail locking car 500 in the rail transport vehicle group and drop it to the rail to be collected. After the rail lifting device 510 is fixedly connected to the rail to be collected, control the rail lifting device 510 to lift the rail to be collected and drop it onto the rail transport vehicle group.

[0080] Step 3: The rail transport vehicle drives out of the construction area.

[0081] If the safety car is provided with a safety door 310 and the rail locking device 520 is provided on the rail locking car, before executing step 2, the safety door 310 and the rail locking device 520 need to be opened to facilitate rail collection; and after step 2 is completed and before executing step 3, the safety door 310 and the rail locking device 520 need to be closed so that the movement of the rails carried on the rail transport vehicle set is restricted by the rail locking device 520 and the safety door 310, so as to avoid safety accidents caused by the rails jumping out during transportation.
