Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of railway engineering machinery, and in particular to a rail transportation system applied to continuous rail welding and a working method. BACKGROUND

[0002] When the railway rail reaches a certain service life, it usually needs to be replaced. In the process of metro rail replacement, short rails need to be transported to the site by flat cars, and then welded into long rails on the ground through multiple skylight points. In the construction, maintenance and other construction operations of railways, the transportation of rails is essential. At present, long rail transportation cars are mainly used for transporting rails. The current long rail transportation car in China is mainly suitable for national railway lines and is not suitable for narrow working spaces such as subway tunnels. In addition, the current long rail transportation car is not convenient to be connected with rail unloading, rail replacement and other construction vehicles, which reduces the work efficiency. At the same time, the bending of the rail during transportation will cause stress concentration effect, resulting in damage or even rupture of the rail.

[0003] In the prior art, Liu Xuexia applied for a Chinese invention application on May 23, 2021, and it was publicly disclosed on September 3, 2021, with the publication number CN113335316A, which discloses a rail transportation flat car for subway construction. The rail transportation flat car comprises: a track horizontally arranged in the tunnel and arranged along the length direction of the tunnel; a car body arranged on the track, the car body comprising a horizontally arranged mounting plate and a top plate; a walking mechanism arranged below the car body, the car body moving along the length direction of the track on the track through the walking mechanism; a sleeper bearing mechanism arranged on the car body and located at the front end of the top of the car body; a rail bearing mechanism arranged on the car body, the length direction of the rail bearing mechanism being consistent with the length direction of the track; and a transportation feeding mechanism arranged on the rail bearing mechanism. The rail transportation flat car for subway construction can carry rails and sleepers in the track through the flat car, transport a large number of sleepers and rails to the construction position, improve the carrying capacity, reduce the labor intensity, avoid multiple carrying, improve the work efficiency, and improve the practicality of the equipment. Although the application discloses a technical solution for bearing and transporting rails and sleepers in subway construction, it is not suitable for the transportation of rails with a length of one hundred meters.

[0004] Therefore, the existing rail transportation car still has the following technical defects:

[0005] 1) The existing rail transportation car is mainly suitable for national railway lines and is not suitable for narrow working spaces such as subway tunnels. In addition, the existing rail transportation car is not convenient to be connected with rail unloading, rail replacement and other construction vehicles, which reduces the work efficiency.

[0006] 2) The existing rail transport operation vehicle mainly relies on ordinary flat cars with rolling beam devices to transport long rails. In the transportation of rails, the bending of the rails will cause stress concentration effect. The transformation of the bending deformation position of the rails not only requires a long deformation space, but also easily leads to damage or even breakage of the rails. In addition, although the rolling beam structure increases the number of rails transported at one time, it makes it difficult for personnel to pass through the rail transport vehicle and unable to carry other operation devices, which is not suitable for construction sites such as subways that require small number of rails transported at one time but have requirements for the length and space of the whole vehicle.

[0007] 3) The existing rail transport operation vehicle does not have the overall conveying capacity of simultaneously adjusting the horizontal position, vertical position and longitudinal conveying of the rails. SUMMARY

[0008] Therefore, the purpose of the present application is to provide a rail transportation system and operation method to solve the technical problems of low efficiency and unsuitability for narrow operation space such as subway tunnels of the existing rail transportation system and operation method.

[0009] In order to achieve the above-mentioned purpose of the application, the present application specifically provides a technical implementation scheme of a rail transportation system, which comprises:

[0011] A plurality of jacking conveying devices are arranged on the first flat car in the longitudinal direction, and the jacking conveying devices are used for jacking and longitudinal conveying of the rails.

[0012] The first flat car is also provided with a horizontal pushing device, and the horizontal pushing device is used for horizontally conveying the rails on the jacking conveying device to a designated position on the first flat car.

[0013] When loading the rails, the rails are conveyed to the designated position by the jacking conveying device from one end of the first flat car, then the jacking conveying device is lowered, and the rails fall onto the horizontal pushing device. The horizontal pushing device horizontally conveys the rails to the designated position on the first flat car for storage.

[0014] Further, when unloading the rails, the horizontal pushing device moves horizontally to push the stored rails to the designated position, the jacking conveying device rises and jacks up the rails, and the rails are conveyed longitudinally to leave the first flat car.

[0015] Further, the horizontal pushing device is arranged in pairs and spaced apart in the longitudinal direction of the first flat car, and moves the rails horizontally to the two sides of the first flat car for storage.

[0016] Further, the first flat car is provided with a rail storage platform for storing rails, and an arch is arranged in the middle of the first flat car in the longitudinal direction for passing the rails, and the arch is located on the upper part of the lifting conveying device.

[0018] Further, a plurality of first flat cars are coupled to form a storage space for rails of a desired length.

[0019] Further, the first flat car is provided with a fixed pulley. When it is necessary to convey the rails to the first flat car for storage, one end of the traction device is connected to the rails after passing through the fixed pulley, and the other end is connected to the pushing device. When it is necessary to unload the rails to the ground, one end of the traction device is connected to the rails, and the other end is connected to the pushing device.

[0020] The present application further specifically provides a technical implementation scheme of a rail transportation operation method, which comprises the following steps:

[0021] S1) Before the rail transportation operation, when loading the rails, a plurality of first flat cars are coupled by car couplings, the rails are conveyed from one end of the first flat car to the lifting conveying device, and the rails are pushed to the designated position by the lifting conveying device;

[0022] S2) The lifting conveying device is lowered to make the rails fall onto the transverse pushing device, the transverse pushing device is moved to the designated position in the transverse direction, and a plurality of rails are sequentially stored under the rail storage platform;

[0023] S3) During the rail transportation operation, the first flat car is coupled with the traction vehicle to transfer the rails;

[0024] S4) After the rail transportation operation, when unloading the rails, the transverse pushing device moves in the transverse direction to push the stored rails to the middle position, the rails are lifted by the lifting conveying device, and the rails are pushed away from the first flat car in the longitudinal direction.

[0025] Further, before the rail transportation operation, short rails are welded into long rails, and the long rails are conveyed to the first flat car by the lifting conveying device.

[0026] Further, before the rail unloading operation, the rails are conveyed away from the first flat car by the lifting conveying device, and long rails are welded into longer rails.

[0027] Further, in the step S2), the transverse pushing device moves towards the transverse sides of the first flat car to sequentially store a plurality of rails under the space on both sides of the rail storage platform.

[0028] Further, in the step S1), the steel rail is conveyed by the space of the middle arch of the track storage platform to the jacking conveying device of the first flat car.

[0029] Further, in the step S4), the jacking conveying device jacks up the steel rail to the space of the middle arch of the track storage platform, and pushes the steel rail longitudinally away from the first flat car.

DETAILED DESCRIPTION

[0055] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0056] As shown in the drawings, Figure 1 to Figure 19 the specific embodiments of the rail transport system and operation method of the present application are given, and the present application will be further described below in conjunction with the drawings and specific embodiments.

[0057] Embodiment 1

[0058] As shown in the drawings, Figure 1 to Figure 3As shown, an embodiment of the rail transport system of the present application specifically comprises:

[0059] A first flat car 2 (i.e. rail transport car) for storing and transporting the rails 23.

[0060] A plurality of jacking and conveying devices 13 are longitudinally spaced apart on the first flat car 2, and are used for jacking and longitudinally conveying the rails 23.

[0061] The first flat car 2 is also provided with lateral pushing devices 14, which are used for conveying the rails 23 on the jacking and conveying devices 13 as a whole to the designated positions on the first flat car 2 in the lateral direction.

[0062] As shown in the accompanying drawings, Figure 4 The lateral pushing devices 14 are used for conveying the rails 23 on the jacking and conveying devices 13 as a whole to the designated positions on the first flat car 2 in the lateral direction (as shown by W in the accompanying drawings). The lateral pushing devices 14 are spaced apart in pairs in the longitudinal direction of the first flat car 2 (as shown by L in the accompanying drawings), and are used for moving the rails 23 to the two sides of the first flat car 2 for storage. The lateral pushing devices 14 and the jacking and conveying devices 13 realize the overall smooth driving of the rails 23, and the transfer process is completely automated. On the basis of realizing the overall transfer and conveying of the rails, not only the space is saved, but also the quality of the rails 23 is guaranteed.

[0063] As shown in the accompanying drawings, Figure 4 to the accompanying drawings, Figure 6As shown, the first flat car 2 is provided with a rail storage platform 19 for storing the steel rail 23, and the middle part of the first flat car 2 in the longitudinal direction is provided with an arch 20 for passing the steel rail 23 (as a conveying line of the steel rail 23), and the arch 20 is located at the upper part of the jacking conveying device 13. The rail storage platform 17 is a way of storing the steel rail 23, and when the steel rail 23 is stored in a horizontal moving manner, the steel rail 23 can be moved horizontally and stored on the rail storage platform 19. On both sides of the arch 20 in the transverse direction, the upper part of the rail storage platform 19 is provided with a walkway 18 for personnel to walk and place equipment, and the outer side of the walkway 18 is provided with a guardrail 21. The walkway 18 is used to form a passageway for personnel to walk above the rail storage platform 19, which can facilitate maintenance and movement on the flat car. The guardrail 21 is used to protect personnel when walking on the walkway. The rail storage platform 19 with the arch 20 in the middle part is used in combination with the jacking conveying device 13 arranged in the longitudinal direction and the transverse pushing device 14, and no stress concentration is generated during the conveying of the steel rail 23, which is especially suitable for combined construction with rail unloading and rail changing construction vehicles in a narrow space such as a subway or a tunnel, and is connected to the rail storage and rail conveying part to realize the simultaneous storage of the steel rail 23 on the rail conveying vehicle, and the function of personnel and placement of the operation device. The embodiment adopts the technical scheme of horizontal movement of the whole steel rail, saves the transition length required for deformation of the steel rail, and removes the transition car, so that the overall length of the vehicle is greatly reduced.

[0064] When the steel rail 23 is loaded, the steel rail 23 is conveyed from one end of the first flat car 2 to the designated position through the arch 20 in the middle part by the jacking conveying device 13, then the jacking conveying device 13 is lowered, and the steel rail 23 falls onto the transverse pushing device 14. The transverse pushing device 14 conveys the steel rail 23 in the transverse direction to the designated position on the first flat car 2 for storage.

[0065] When the steel rail 23 is unloaded, the transverse pushing device 14 moves laterally to push the stored steel rail 23 to the position below the arch 20 in the middle part of the first flat car 2, the jacking conveying device 13 lifts and jacks up the steel rail 23, and conveys the steel rail 23 in the longitudinal direction to leave the first flat car 2.

[0066] A plurality of first flat cars 2 are connected to form a storage space for the required length of steel rail 23, and after connection, the loading and transportation of the long steel rail can be realized. The first flat car 2 is provided with a fixed pulley 17. When the steel rail 23 needs to be transported to the storage space on the first flat car 2, one end of the traction device 16 is connected to the steel rail 23 after passing through the fixed pulley 17, and the other end is connected to the pushing device 15. When the steel rail 23 needs to be unloaded to the ground, one end of the traction device 16 is connected to the steel rail 23, and the other end is connected to the pushing device 15. As a typical embodiment of the present application, the pushing device 15 can further specifically adopt a winch to realize the traction and pushing of the steel rail 23 as a supplement to the jacking conveying device 13. The pushing device 15 is provided with a traction device 16, which can further specifically adopt a steel wire rope. In this embodiment, the winch is only one of the structure implementation schemes, and is not limited to the implementation mode of the winch and the steel wire rope. Other modes can also be used to realize the transportation of the steel rail 23, such as the use of self-powered rail clamping wheels on the left and right sides of the steel rail 23 to realize the transportation of the steel rail 23. The fixed pulley 17 is used to cooperate with the steel wire rope and the winch to realize the pushing of the steel rail 23.

[0067] The steel rail transportation system described in embodiment 1 realizes the stable transfer and transportation of the whole steel rail through the jacking conveying device and the transverse pushing device, and the transfer process is completely automated. The space is saved while effectively ensuring the quality of the steel rail, especially suitable for use in narrow space construction environments such as subways, as a rail storage and transportation part connected to construction vehicles such as rail unloading and changing. The steel rail transportation system has high automation, saves space and the length of the whole vehicle, can realize welding, transportation, unloading and changing of the rail, and has flexible grouping and operation mode, high degree of mechanization, improves operation efficiency, saves a large amount of labor, and can well adapt to the characteristics of short sky window period of subway rail changing operation. At the same time, the steel rail transportation system uses a rail storage rack with a central arch to cooperate with the longitudinal jacking conveying device and the transverse pushing device, so that stress concentration does not occur during the transportation of the steel rail. At the same time, a walkway is provided for personnel to walk and place other equipment, so that the rail transportation flat car can store rails, pass personnel and place operation devices at the same time.

[0068] Embodiment 2

[0069] An embodiment of a steel rail transportation operation method based on the system described in embodiment 1 of the present application, specifically comprising the following steps:

[0070] S1) Before the rail operation, when loading the steel rail 23, a plurality of first flat cars 2 are connected through the coupler 11, the steel rail 23 is transported from one end of the first flat car 2 to the jacking conveying device 13, and the steel rail 23 is pushed to the designated position through the jacking conveying device 13;

[0071] S2) The lifting and conveying device 13 is lowered, and the steel rails 23 are dropped onto the lateral pushing device 14, which is moved laterally to the designated position, and the steel rails 23 are sequentially stored under the storage rail platform 19;

[0072] S3) During the rail transportation operation, the first flat car 2 is coupled with the tractor 1, and the steel rails 23 are transported and transferred.

[0073] S4) After the rail transportation operation, the steel rails 23 are unloaded, and the lateral pushing device 14 is moved laterally to push the stored steel rails 23 to the middle position, the lifting and conveying device 13 lifts the steel rails 23, and the steel rails 23 are pushed longitudinally away from the first flat car 2.

[0074] Before the rail transportation operation, the short steel rails are welded into long steel rails, and are conveyed to the first flat car 2 by the lifting and conveying device 13.

[0075] Before the rail unloading operation, the steel rails 23 are conveyed away from the first flat car 2 by the lifting and conveying device 13, and the long steel rails are welded into longer steel rails.

[0076] In the above step S2), the lateral pushing device 14 is moved towards the lateral sides of the first flat car 2, and the steel rails 23 are sequentially stored under the space on both sides of the storage rail platform 19. When the steel rails 23 are loaded, the steel rails 23 are conveyed from one end of the first flat car 2 to the lifting and conveying device 13 through the arch 20 in the middle, and the steel rails 23 are pushed to the designated position by the lifting and conveying device 13. After reaching the designated position, the lifting and conveying device 13 is lowered, and the steel rails 23 are dropped onto the lateral pushing device 14, which is moved laterally to the two sides of the first flat car 2, and the steel rails 23 are sequentially stored under the storage rail platform 19.

[0077] In the above step S1), the steel rails 23 are conveyed from one end to the lifting and conveying device 13 of the first flat car 2 through the space of the arch 20 in the middle of the storage rail platform 19.

[0078] In the above step S4), the lifting and conveying device 13 lifts the steel rails 23 to the space of the arch 20 in the middle of the storage rail platform 19, and pushes the steel rails 23 longitudinally away from the first flat car 2. When the steel rails 23 are unloaded, the lateral pushing device 14 is moved laterally to push the stored steel rails 23 to the position under the arch 20 in the middle of the first flat car 2, the lifting and conveying device 13 lifts the steel rails 23, and the steel rails 23 are pushed longitudinally away from the first flat car 2.

[0079] The rail transportation method described in embodiment 2 is that the rail 23 is placed on the rail transport car by the lifting conveying device 13 and the transverse pushing device 14 after the welding and grinding treatment on the flat car, which not only facilitates the transportation of the rail 23, but also has high mechanization degree and high operation efficiency, and saves a large amount of labor. The rail transportation method of the application can complete synchronous operation of welding and grinding, effectively connect the pre-treatment before welding and the transportation process after grinding, and provide the possibility for realizing the integrated operation of metro overhaul of collecting rails, welding rails, grinding and replacing rails.

[0096] After the rail conveying operation, when the steel rails 23 are unloaded, the transverse pushing device 14 moves in the transverse direction to push the stored steel rails 23 to the middle position, the jacking conveying device 13 jacks up the steel rails 23, and the steel rails 23 are pushed to leave the first flat car 2 in the longitudinal direction.

[0097] ​​​As a preferred embodiment of the present application, the distance between the welding module 7 and the grinding module 9 is the length of a standard rail 23, so that the previous joint is ground while the current joint of the rail 23 is welded. For example, the distance between the welding module 7 on the second flat car 3 and the grinding module 9 on the third flat car 8 is 25 m, which is used to process two welded joints while welding a 25 m standard short rail, and to grind the previous welded joint while welding the current joint, so that the welding and grinding of the rail 23 can be synchronized during the track laying, greatly improving the efficiency of the track laying operation. When welding short rails of other lengths, only the distance between the welding module 7 and the grinding module 9 needs to be adjusted.

[0098] As a typical embodiment of the present application, the continuous rail welding operation system has two operation scenarios in actual use. One scenario is in the base, and the 25 m short rail on the track laying car 4 is transported to the welding module 7, and the welding module 7 welds the 25 m short rail into a 100 m long rail. Two parallel operation rail conveying lines can be arranged on the track laying car 4, the first conveying line is used for pre-welding treatment (such as rust removal), and the second conveying line leads to the welding module 7 for welding treatment. The rail 23 is lifted by the jacking conveying device 13 after the pre-treatment on the first conveying line, and is transferred to the second conveying line for welding operation, so that the pre-treatment and welding treatment can be synchronized, thereby realizing the synchronization of welding and rust removal, and further improving the operation efficiency. Another scenario is at the construction site, and the long rail on the rail transport car (i.e. the first flat car 2) is transported to the rail welding car (i.e. the second flat car 3), and the 100 m long rail is welded into a long rail strip of several hundred meters (usually 500 m), which is unloaded to the ground by the rail unloading car 5 or the rail changing car 6 (or directly changed into the rail bearing groove). The rail 23 has three different forms according to different operation states, one is a short rail before track laying, the other is a long rail after welding and grinding stored on the rail transport car, and the third is a long rail strip after welding and unloading to the ground.

[0099] Before the steel rail welding operation, two 25m short steel rails after the pre-welding treatment (such as rust removal) are longitudinally conveyed by the jacking conveying device 14 to the rail welding vehicle and the rail grinding vehicle, and the welding is completed by the welding equipment at the welding module 7 and the normalizing cooling treatment is performed, and the 50m steel rail after the treatment is longitudinally conveyed by the jacking conveying device 14. When the first rail joint reaches the position of the grinding module 9, the third 25m short steel rail after the pre-treatment continues to be welded at the welding module 7 to obtain a 75m steel rail. At the same time, the grinding module 9 performs the grinding and flaw detection treatment on the first joint. In this way, the welding and grinding operations are continuously and synchronously performed until the long steel rail with the required length (such as 100m) is obtained. After the long steel rail with the required length is obtained, the jacking conveying device 13 arranged longitudinally continues to drive the steel rail 23 to move longitudinally, and after the steel rail 23 reaches the rail vehicle, the jacking conveying device 14 is lowered, the long steel rail falls onto the horizontal pushing device 14, the horizontal pushing device 14 moves horizontally along the horizontal direction, and the long steel rail is sequentially stored on the rail storage platform 19, and the rail welding and grinding operation is completed.

[0100] The continuous rail welding operation system described in Embodiment 3 is used for the rail unloading, and the rail grinding operation is performed on the ground, and the first skylight is only used for the welding and unloading of the steel rail 23, and the next skylight is used for the grinding operation of the rail welding joint (performed manually on the ground).

[0101] The continuous rail welding operation system described in Embodiment 3 cancels the fastener dismounting vehicle and the transition vehicle, greatly reduces the length of the whole vehicle, saves the space, facilitates the storage of the whole vehicle on the metro storage track, has high automation degree, and has flexible marshalling, which is well adapted to the operation conditions in the metro tunnel and the short skylight of the metro rail replacement operation.
