Abstract

In an embodiment of the present application, a railway operation device circulation system and a railway operation device circulation method are provided, including a frame, a closed-loop circulation track, an operation device, and a power driving device. The power driving devices correspond one-to-one to the closed-loop circulation tracks, are fixed on the frame and connected to the operation device. The power driving devices drive the operation device to rotate along the closed-loop circulation track. When the operation device moves to the lower side of the closed-loop circulation track, the operation device and the frame move in opposite directions. The power driving device adjusts the running speed of the operation device to be the same as that of the frame, so that the operation device remains stationary relative to the railway track and performs maintenance operations on the points to be repaired on the railway track. The above system has the power driving devices corresponding one-to-one to the closed-loop circulation tracks, reducing the number of mechanisms required for the operation device in the circulation system, simplifying the system structure, eliminating the need to set up alignment mechanisms for alignment between the circulation tracks, reducing the operation difficulty of the system, and improving the reliability of the system.

Description

Technical Field

[0001] This application relates to the technical field of railway engineering machinery. Specifically, it relates to a circulating system for a railway working device and a circulating method for a railway working device. Background Art

[0002] Currently, in track maintenance operations, especially some maintenance operations that require relative stillness with the railway track and cannot be carried out during the movement of the working device, many times they are completed by manual use of small tools. Such a construction method has a large demand for labor, difficult construction site management, and high labor costs. Due to the harsh working environment and high work intensity, the potential safety hazards are relatively serious.

[0003] There are also some technical solutions in the industry to solve the above problems. For example, a circulating system is provided for circulating and transporting a railway working device, so that when the working device reaches the lower position, it falls onto the railway rail, and then through a positioning mechanism, the working device reaches the working position and remains relatively stationary with the rail, and starts to operate on the track. Finally, the working device reaches the lower part of the rear end of the circulating system and enters the next circulating transport. This circulating system is mainly composed of an engineering working vehicle frame, a landing mechanism, a lower support mechanism, a lifting mechanism, an upper horizontal transport mechanism, and a positioning mechanism, and the actions of each mechanism are independent of each other.

[0004] In the above circulating system, in order to enable the working device to move smoothly in the circulating system, it is necessary for the structures of each mechanism to be accurately connected and the action control to be precisely matched, which requires high production and control requirements for the circulating system, and too many mechanisms and controls will reduce the reliability of the entire system.

[0099] The embodiment of the present invention discloses a circulating system for a railway working device to solve the problems in the existing circulating system that several action mechanisms need to be set to ensure the smooth operation of the working device in the circulating system, the structure is complex, and the system reliability is low.

[0100] To make the technical solutions and advantages in the embodiments of the present application clearer and more understandable, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0101] Please refer to Figures 1-3 , Figure 1 which is the front view structural schematic diagram of a circulating system of a railway operation device 3 provided by an embodiment of the present application; Figure 2 is Figure 1 the top view structural schematic diagram of; Figure 3 which is the front view structural schematic diagram of the frame 1 provided by an embodiment of the present application.

[0102] In a specific implementation manner, an embodiment of the present application provides a circulating system of a railway operation device 3, including a frame 1, a closed circulating track 2, and an operation device 3. Among them, the frame 1 can be set as a rectangular frame 71. The frame 1 is arranged above the railway track and can move relative to the railway track. Preferably, the frame 1 includes a connecting frame 11 and frame traveling wheels 12. The closed circulating track 2, the operation device 3, and the power driving device 5 are fixed on the connecting frame 11; the frame traveling wheels 12 are rotatably connected to the lower part of the connecting frame 11 for cooperation with the railway track.

[0103] The closed circulating track 2 is vertically fixed on the frame 1. The closed circulating track 2 is arranged along the length direction of the frame 1. The closed circulating track 2 is preferably arranged in a vertical plane. The closed circulating track 2 and the frame 1 are detachably connected. The operation device 3 is arranged on the closed circulating track 2 and rotates along the closed circulating track 2 so as to be able to perform maintenance operations on the points to be maintained on the railway track when moving to the lower side of the closed circulating track 2.

[0104] Among them, the power driving device 5 is arranged corresponding to the closed circulating track 2 one by one, so as to realize the circulating operation of the operation device 3 on the entire closed circulating track 2 through one power driving device 5. Compared with the prior art, the number of mechanisms is reduced, and there is no need to set a positioning mechanism for positioning between the circulating tracks, improving the reliability of the system. Specifically, the power driving device 5 is fixed on the frame 1 and connected to the operation device 3. The power driving device 5 drives the operation device 3 to rotate along the closed circulating track 2. When the operation device 3 moves to the lower side of the closed circulating track 2, the running directions of the operation device 3 and the frame 1 are opposite. The power driving device 5 adjusts the running speed of the operation device 3 to be the same as the running speed of the frame 1, so that the operation device 3 remains stationary relative to the railway track and performs maintenance operations on the points to be maintained on the railway track.

[0105] Adopting a circulation system of a railway operation device 3 provided in the embodiments of the present application, compared with the prior art, has the following technical effects:

[0106] By arranging a closed-loop circulation track 2 vertically and along the length direction of the frame 1, the power driving device 5 drives the operation device 3 to rotate on the closed-loop circulation track 2. When the operation device 3 moves to the lower side of the closed-loop circulation track 2, the running directions of the operation device 3 and the frame 1 are opposite. The power driving device 5 adjusts the running speed of the operation device 3 to be the same as that of the frame 1, so that the operation device 3 remains stationary relative to the railway track, and the operation device 3 can perform maintenance operations on the railway track. The above system realizes the circulation operation of the operation device 3 by arranging the closed-loop circulation track 2, and the power driving device 5 corresponds to the closed-loop circulation track 2 one by one. Compared with the prior art, the number of mechanisms required for the operation device 3 in the circulation system is reduced, the system structure is simplified, there is no need to set a positioning mechanism for positioning between the circulation tracks, the system operation difficulty is reduced, and the system reliability is improved.

[0107] As Figures 4-6 shown in Figure 4 FIG. 11 is a front view structural schematic diagram of the closed-loop circulation track 2 provided by the embodiments of the present application; Figure 5 is Figure 4 a top view structural schematic diagram of Figure 6 is Figure 4 a side view structural schematic diagram of Figure 11 FIG. 21 is a structural schematic diagram of the circulation support track 61 provided by the embodiments of the present application.

[0108] Specifically, the closed-loop circulation track 2 includes a track bracket 21, a gear member 23, and a chain rack 24. The track bracket 21 is arranged longitudinally along the frame 1, that is, the length direction of the frame 1. The number of gear members 23 is two, which are respectively rotatably arranged at both longitudinal ends of the track bracket 21. The gear member 23 is connected to the power driving device 5 to serve as a power source for driving the chain rack 24 to rotate; the chain rack 24 meshes with the gear member 23 and is laid along the outer wall of the circumference of the track bracket 21. The track bracket 21 is used to support the chain rack 24 and the operation device 3 arranged thereon. The operation device 3 is connected to the chain rack 24, such as detachably connected, realized by a threaded fastener 74, so that the operation device 3 rotates driven by the chain rack 24. The power driving device 5 drives the gear member 23 to rotate, the chain rack 24 meshes with the gear member 23, and the chain rack 24 drives the operation device 3 to rotate relative to the frame 1. The above device provides a passive power source, and the operation device 3 runs passively on the closed-loop circulation track 2.

[0109] The chain rack 24 can be set as a chain or a rack, and the gear member 23 can be set as a gear tooth or a gear to cooperate with the chain rack 24 respectively. Further, the circulating system can be designed such that the chain is fixed and there is no power mechanism, and the sprocket on the working device 3 cooperates with the chain. By controlling the driving mechanism of the sprocket on the working device 3, the working device 3 can perform a circulating motion inside the circulating system.

[0110] As Figures 12-16 shown, Figure 12 This is a schematic structural diagram of the working device 3 provided by an embodiment of the present application;

[0111] Figure 13 For Figure 12 the side view structural diagram; Figure 14 This is an isometric structural diagram of the working device 3 provided by an embodiment of the present application; Figure 15 This is an installation structural diagram of the working device 3 provided by an embodiment of the present application; Figure 16 For Figure 15 the lateral structural diagram.

[0112] In another embodiment, the working device 3 includes a working gear member 33 and a working power driving mechanism. The working gear member 33 meshes with the chain rack 24; the working power driving mechanism is connected to the working gear member 33 and is used to drive the working gear member 33 to rotate on the chain rack 24, so that the working device 3 makes a relative movement with respect to the chain rack 24, thereby realizing the active walking of the working device 3 on the chain rack 24. When applied, when the working device 3 runs to the lower side of the closed circulating track 2 and there is a position deviation between the working device 3 and the maintenance point of the railway track, the working power driving mechanism can be used to drive the working gear member 33 to rotate on the chain rack 24 to finely adjust the position of the working device 3 with respect to the railway track and improve the maintenance operation accuracy. Specifically, in order to prevent the working device 3 from slipping or shifting at the turning and lower positions of the closed circulating track 2, when the working power driving mechanism stops working and locks itself, the working gear member 33 and the chain rack 24 are locked to lock, and at this time, the working gear member 33 and the chain rack 24 cannot move relatively. Further, in order to optimize the locking effect, the working device 3 further includes a locking component for locking or unlocking the working device 3 and the chain rack 24. After locking, the working device 3 and the chain rack 24 are fixed, so that the working device 3 remains fixed at the lower side and turning of the closed circulating track 2 and does not slip. In the locked state, the working power driving mechanism cannot drive the working gear member 33 to rotate and mesh with the chain rack 24, but the working device 3 can move synchronously under the drive of the chain rack 24; when unlocked, the working device 3 can make a relative movement with respect to the chain rack 24 under the drive of the working power driving mechanism to realize the individual adjustment of the position of the working device 3.

[0113] Specifically, the locking component includes:

[0114] An electromagnet, which is used to generate a magnetic force when powered on and attract the chain rack 24;

[0115] An electromagnet moving power mechanism, which is connected to the electromagnet and drives the electromagnet to move towards or away from the chain rack 24. When the electromagnet moving power mechanism drives the electromagnet to move into contact with the chain rack 24, the electromagnet is powered on and attracts the chain rack 24, and the working device 3 and the chain rack 24 are locked; when the electromagnet is powered off, there is no magnetic force with the chain rack 24, and the working device 3 and the chain rack 24 are unlocked. It can be understood that the chain rack 24 is made of metal material or other magnetic materials to enable cooperation with the electromagnet and realize the fixation of the working device 3 on the chain rack 24. This is only a preferred implementation, and in other embodiments, the specific structure of the locking component can be set as needed, all within the protection scope of this application.

[0116] Among them, the working device 3 further includes a working frame 34, a working mechanism 31 and lower traveling wheels 32. The working wheel tooth part 33, the working power driving mechanism and the locking component are all arranged on the working frame 34; the working mechanism 31 is used to perform maintenance operations on the points to be maintained on the railway track. For example, it is set as a working wrench to screw the threaded parts on the railway track. In other embodiments, the specific form of the working mechanism 31 can be set as needed. The lower traveling wheels 32 are arranged at the bottom of the working frame 34. The working frame 34 is preferably a rectangular frame 71, and two lower traveling wheels 32 are respectively arranged on a set of opposite sides of the rectangular frame 71 for supporting the working device 3 in cooperation with the railway track. With this setting, when the working device 3 runs on the lower track of the closed loop track 2, the working device 3 can be supported by the lower traveling wheels 32, so that the working device 3 runs stably on the lower track, reduces jitter, further maintains the relative static state of the working device 3 and the railway track, and reduces the difficulty of maintenance operations.

[0117] In another embodiment, in order to prevent the working device 3 from slipping off the closed loop track 2, the system further includes an anti-slip component 6, which is fixed on the frame 1 and is used to support the rotation of the working device 3 on the closed loop track 2, and when the working device 3 rotates to the turning point of the closed loop track 2, it prevents the working device 3 from slipping off the closed loop track 2. The anti-slip component 6 can be a clamping structure arranged on the closed loop track 2, and the working device 3 and the closed loop track 2 are fixed through the clamping structure manually to achieve anti-slip. The clamping structure is set as a buckle, and the specific structure of the anti-slip component 6 can be set as needed as long as the same technical effect can be achieved.

[0118] In one embodiment, the anti - detachment assembly 6 includes a circulating support track 61 and a support roller set 62. The circulating support track 61 is fixed to the frame 1 and arranged parallel to the chain rack 24. The chain rack 24 serves as the power source for the movement of the working device 3, and the circulating support track 61 serves as an auxiliary support structure for the circulating movement of the working device 3. They cooperate with the chain rack 24 to provide support for the circulating movement of the working device 3.

[0119] The support roller set 62 is arranged on the working device 3. The support roller set 62 includes a roller mounting plate 221, an outer support roller, and an inner support roller. The roller mounting plate 221 is preferably a rectangular plate. The outer support roller and the inner support roller are arranged at both ends in the length direction of the rectangular plate and are symmetrically arranged with respect to the center of the rectangular plate. At the same time, the roller mounting plate 221 rotates around its own center, and the outer support roller and the inner support roller can rotate around their own axes. A circulating support track 61 is provided between the outer support roller and the inner support roller to limit the movement of the working device 3 when it detaches from the circulating support track 61; when passing through the turning point of the closed - loop track 2, the roller mounting plate 221 can rotate along with the track at the turning point, so that the outer support roller and the inner support roller can respectively contact and fit with the track at the turning point to achieve support.

[0120] The specific operation process is as follows: When the working device 3 is on the upper track of the circulating support track 61, under the action of gravity, the outer support roller contacts the circulating support track 61 to support the working device 3. When the working device 3 is on the lower track of the circulating support track 61, the inner support roller hangs above the circulating support track 61 and contacts the circulating support track 61 to provide hanging support for the working device 3; when the working device 3 is at the turning point of the circulating support track 61, the roller mounting plate 221 rotates around its own center, so that the outer support roller and the inner support roller run along the turning - point track of the circulating support track 61 and respectively contact and support the outer wall and the inner wall of the circulating support track 61, preventing the working device 3 from slipping at the turning point and improving the operation reliability of the working device 3.

[0121] Furthermore, in order to limit the lateral movement of the working device 3, limiting grooves are circumferentially provided on the side walls of the outer support roller and the inner support roller, and limiting protrusions are provided on the circulating support track 61. The limiting protrusions cooperate with the limiting grooves to limit the axial movement of the outer support roller and the inner support roller, thereby further ensuring the relative static state between the working device 3 and the railway track, improving the stability of the working device 3 during maintenance operations, and improving the maintenance efficiency and maintenance operation accuracy. The limiting groove is set as a limiting groove with a rectangular cross - section.

[0122] In one embodiment, the circulating support track 61 includes a first circulating support track 61 and a second circulating support track 61. The first circulating support track 61 and the second circulating support track 61 are symmetrically arranged along the longitudinal center line of the frame 1. A limiting projection is provided on one of the first circulating support track 61 and the second circulating support track 61. The support roller set 62 includes a first support roller set 62 and a second support roller set 62. The first support roller set 62 and the second support roller set 62 are symmetrically arranged along the center line of the working device 3. A limiting groove is provided on one of the first support roller set 62 and the second support roller set 62. Specifically, the second circulating support track 61 and the second support roller set 62 are in contact and cooperation through the limiting projection and the limiting groove to limit the axial movement of the working device 3 along the second support roller set 62. The contact surface between the first circulating support track 61 and the first support roller set 62 is a plane to release the degree of freedom of the working device 3 on the first circulating support track 61 and prevent the movement of the circulating support roller set 62 on the circulating support track 61 from being restricted due to installation errors or processing errors.

[0123] As Figure 10 shown, Figure 10 is a schematic structural diagram of the trolley wire 41 power supply device 4 provided by the embodiment of the present application. In another embodiment, in order to facilitate the working device 3 to obtain power for maintenance operations, the above system further includes a trolley wire 41 power supply device 4. The trolley wire 41 power supply device 4 includes a trolley wire 41 and a current collector 42. Among them, the trolley wire 41 is fixed to the track support 21 along the length direction; preferably, it is arranged on the upper side and the lower side of the chain rack 24 and is parallel to the chain rack 24. The current collector 42 is fixed to the working device 3. When the working device 3 moves relative to the frame 1, the current collector 42 slides on the trolley wire 41 to take power and supply it to the working device 3 for operation. This setting eliminates the need for the working device 3 to externally connect cables or other power equipment, simplifies the external equipment of the working device 3, makes it lightweight, so as to facilitate running on the closed circulating track 2, and prevents the cables from interfering with the track or other components and affecting the circulating movement of the working device 3.

[0124] As Figures 8-9 shown, Figure 8 is a schematic structural diagram of the track support 21 provided by the embodiment of the present application; Figure 9 is Figure 8Schematic diagram of the partial enlarged structure at position A in the figure. At the same time, in order to keep the chain rack 24 always in a tensioned state, the above system further includes a tensioning device 7 provided on the track bracket 21. The tensioning device 7 includes a driving tensioning wheel assembly and a driven tensioning wheel assembly 72. The driven tensioning wheel assembly 72 includes a set of driven tensioning wheels and a driven mounting frame. The driven mounting frame is fixed on the track bracket 21, and the driven tensioning wheels are rotatably provided at both ends in the length direction of the driven mounting frame; a preset interval is provided between the driven tensioning wheels. The driving tensioning wheel assembly includes a set of driving tensioning wheels and a driving mounting frame. The driving mounting frame and the driven mounting frame are relatively fixed. The driving tensioning wheels are rotatably provided at both ends in the length direction of the driving mounting frame and are provided with a preset interval. The chain rack 24 meshes with the driven tensioning wheels and the driving tensioning wheels respectively. It passes upward through the driven tensioning wheels to contact the two driving tensioning wheels and then downward from the other end of the driving tensioning wheels to contact another driven tensioning wheel. It can be understood that the center distance between adjacent driving tensioning wheels is adjustable. When the center distance of the driving tensioning wheels increases, the chain rack 24 is tensioned. With this setting, the tensioned state of the chain rack 24 is always maintained, so that it can always contact the working device 3 and drive the working device 3 to move along the closed-loop track 2.

[0125] Specifically, the driving mounting frame includes a first driving mounting frame and a second driving mounting frame. The first driving mounting frame and the second driving mounting frame are coplanar and parallel to the driven mounting frame. The first driving mounting frame and the second driving mounting frame are respectively fixed on the machine frame 1. The first driving mounting frame and the second driving mounting frame each include a rectangular frame 71 and a sliding member. Sliding portions are provided on a set of parallel side walls of the rectangular frame 71; the sliding members are provided at both ends of the wheel axle of the driving tensioning wheels. The sliding members slide along the length direction of the sliding portions. Through the cooperation of the sliding portions and the sliding members, the adjustment of the center distance between the driving tensioning wheels is realized. Among them, the sliding member includes a threaded fastener 74 and a sliding protrusion 73 that cooperates with the sliding portion. One end of the threaded fastener 74 protrudes from the side wall of the rectangular frame 71 and is arranged along the length direction of the sliding portion, and the other end contacts the sliding member to push the driving tensioning wheel to slide along the sliding portion; the sliding portion is a sliding hole or a sliding groove. Preferably, the sliding portion is set as a sliding hole to facilitate the intuitive observation of the distance between the driving tensioning wheels outside the rectangular frame 71. The sliding protrusion 73 is preferably a rectangular protrusion, and the upper and lower surfaces respectively fit with the upper wall and the lower wall of the sliding hole. During use, by screwing the threaded fastener 74, the length of the protruding end in the sliding hole changes, and the sliding protrusion 73 is pushed to slide in the sliding hole. Furthermore, the distance between the driving tensioning wheels increases, and the chain rack 24 is tensioned.

[0126] The track bracket 21 includes an arc-shaped turning portion 211 and a straight portion 212. Adjacent arc-shaped turning portions 211 are connected through the straight portion 212 to form a closed track. There are two arc-shaped turning portions 211 and two straight portions 212, respectively, and they are arranged alternately. In order to support the sprocket 24, the straight portion 212 and the arc-shaped turning portion 211 are hollow shells, and the sprocket 24 is arranged in the hollow shell. The arc-shaped turning portion 211 is a hollow shell with an opening on one side. The gear member 23 is arranged in the hollow shell of the arc-shaped turning portion 211 and meshes with the sprocket 24. The outer wall of any arc-shaped turning portion 211 and the outer wall of the straight portion 212 are provided with a clearance hole arranged continuously in space, which is used to make way for the sprocket 24. The operating device 3 is arranged above the track bracket 21 and connected to the sprocket 24 through the clearance hole.

[0127] In one embodiment, the clearance holes are arranged along the center line of the hollow shell, the sprockets 24 are three groups and fixedly connected, the middle chain corresponds to the clearance hole and meshes with the working gear part 33, and the sprockets 24 on both sides mesh with the gear part 23 respectively. Thus, the shells on both sides of the clearance hole can support the working device 3 as supporting surfaces when the working device 3 is tilted, so as to prevent the working device 3 from overturning and causing a safety accident.

[0128] like Figure 7 As shown, Figure 7 A schematic diagram of the structure of the mounting bracket 22 provided in the embodiment of the present application. In order to facilitate the installation of the circulating support track 61 and the closed circulating track 2, the above system also includes a mounting bracket 22 for fixing to the frame 1; the mounting bracket 22 includes a group of parallel mounting plates 221, a connecting seat 222 and a connecting beam 223. The closed circulating track 2 is fixed to the outer side of the mounting plate 221 through the track bracket 21, and the circulating support track 61 is fixed to the inner side of the mounting plate 221, thereby making the spatial structure compact with a reasonable layout. The connecting seat 222 is fixedly connected to the frame 1 and fixed to the outer side of the mounting plate 221. The connecting beam 223 is arranged between the parallel mounting plates 221, and the two ends in the length direction are respectively fixedly connected to the mounting plates 221 to improve the strength of the mounting plates 221.

[0129] Furthermore, there are two groups of closed loop tracks 2, and the two groups of closed loop tracks 2 are symmetrically arranged along the center line of the connecting frame 11; and a plurality of groups of working devices 3 are arranged on any closed loop track 2. In other embodiments, there are four groups of closed loop tracks 2, which are respectively arranged on the frame 1 and arranged in pairs to provide stable support for the working devices 3.

[0130] The specific operation process of the system is as follows: During operation, the circulating system of the railway operation device 3 moves forward at a constant speed on the rail, and at the same time, the power driving device 5 drives the operation device 3 to perform a circulating motion in the plane perpendicular to the railway track. When the operation device 3 is above the closed circulating track 2, the moving directions of the chain rack 24 and the operation device 3 are the same as the advancing direction of the machine frame 1. When the operation device 3 is below the closed circulating track 2, the moving directions of the chain rack 24 and the operation device 3 are opposite to the advancing direction of the machine frame 1. When the operation device 3 is below the closed circulating track 2, the moving direction is opposite to but the speed is the same as the advancing direction of the machine frame 1, achieving relative static between the operation device 3 and the railway track, and this continues until the operation unit reaches the rear end of the lower track of the closed circulating track 2. During the stage when the operation device 3 and the railway track maintain relative static, the operation device 3 can complete the maintenance operation of the line.

[0131] During the operation process, the operation device 3 and the chain rack 24 are divided into two working conditions. First, when the operation devices 3 are evenly spaced along the track direction on the railway track as the operation objects, the relative positions between the operation devices 3 can be preferentially adjusted according to the relative positions between the operation objects. During operation, the operation devices 3 can sequentially match the operation objects to perform railway maintenance operations. Second, when the operation devices 3 and the operation objects are unevenly spaced along the track direction on the railway track, during the process of the operation device 3 performing a circulating motion along the upper track of the closed circulating track 2, according to the relative positions between the operation objects, control the operation power driving mechanism of the operation device 3 to act, so that the operation gear member 33 meshes with the chain rack 24, and adjust the front and rear positions of the operation device 3 relative to the chain rack 24, so that the spacing between the operation devices 3 matches the spacing between the operation objects, ensuring that the operation device 3 can fall on the preset position of the railway track when it reaches below the closed circulating track 2 and perform the corresponding railway maintenance operation.

[0132] The above-mentioned system operation device 3 makes a circular motion within the closed-loop track 2. When the operation device 3 is below the device, the circular motion speed is equal in magnitude and opposite in direction to the advancing speed of the frame 1. The operation device 3 remains relatively stationary with respect to the railway track until the operation device 3 reaches the rear end of the operation device 3. During the stage of remaining relatively stationary with respect to the railway track, the operation device 3 can perform corresponding railway maintenance operations. Secondly, the closed-loop track 2 is connected end to end without gaps. When the operation device 3 runs on the closed-loop track 2, the support roller group 62 always cooperates with the circular support track 61. Compared with the circular system composed of multiple mechanisms, the operation device 3 runs more safely and smoothly in the circular system. Thirdly, the operation device 3 is driven to make a circular motion by two integral chains. The chains cooperate with the sprockets and make a circular motion driven by a power drive device 5. Compared with the method of driving the operation unit by multiple drive mechanisms, the control of the circular motion is relatively more convenient. Finally, the sprocket of the operation device 3 is designed with an operation power drive mechanism, enabling the operation device 3 to make a circular motion at the same speed as the chain of the circular mechanism and also enabling it to move independently relative to the chain, so that the operation device 3 can operate on operation objects with different spacings on the railway track.

[0133] Based on the above system embodiments, the present application also provides a railway operation device circulation method for a railway operation device circulation system according to any one of the above embodiments. The method includes:

[0134] Driving the frame to move on the railway track at a preset speed, and the operation device rotates on the closed-loop track;

[0136] If so, judging whether the current running speed of the operation device on the closed-loop track is the same as the preset speed of the driven frame;

[0137] When the current running speed of the operation device is not the same as the preset speed of the driven frame, controlling the power drive device to adjust the current running speed of the operation device to be the same as the preset speed of the driven frame;

[0138] Controlling the operation device to perform maintenance operations on the points to be overhauled on the railway track.

[0139] Adopting a railway operation device circulation system and method provided in the embodiments of the present application, compared with the prior art, has the following technical effects:

[0140] By arranging a closed-loop track vertically and along the length direction of the rack, the power driving device drives the working device to rotate on the closed-loop track. When the working device moves to the lower side of the closed-loop track, the running directions of the working device and the rack are opposite. The power driving device adjusts the running speed of the working device to be the same as that of the rack, so that the working device remains stationary relative to the railway track, and the working device can perform maintenance operations on the railway track. The above system realizes the cyclic operation of the working device by arranging the closed-loop track, and the power driving device corresponds to the closed-loop track one by one. Compared with the prior art, the number of mechanisms required by the working device in the cyclic system is reduced, the system structure is simplified, there is no need to arrange an alignment mechanism for alignment between the cyclic tracks, the operation difficulty of the system is reduced, and the reliability of the system is improved.
