Description

Technical Field

[0001] The present invention relates to the field of railway engineering machinery, and in particular to a vertical circulation system of a railway operating device and an operating method thereof. Background Art

[0002] Currently, line maintenance operations, particularly those requiring relative stationary contact with the railway line and unable to be performed while the equipment is in motion, are often performed manually using small tools. This approach requires a large amount of manpower, makes site management difficult, and results in high labor costs. The harsh working environment and high workload also create significant safety risks.

[0003] For example, the Chinese invention patent with publication number CN 108978372 A discloses a bracket for transporting railway sleepers, comprising a base plate, a material placement device, and a support frame. The base plates are two in number and are arranged symmetrically on the left and right. The material placement device is installed on the upper end of the base plate, and the support frame is installed between the two base plates. The material placement device includes a mounting plate, an active roller, a driven roller, an active motor, a conveyor belt, a limit plate, a connecting support plate, a limit cylinder, a material placement plate, a mounting ring, an adjustable electric push rod, an adjustable slide plate, a mounting slide plate, a fixed cylinder, and a fixed pressure plate. This invention can solve the problems of high labor cost, high labor intensity, low work efficiency, inconvenient removal, and easy collision in the existing sleeper transportation process, and can realize the function of orderly transporting sleepers, with the advantages of low labor cost, low labor intensity, high work efficiency, easy removal, and no collision. However, this bracket is only applicable to sleeper transportation, and its operating condition is static, so it will not work during the material transportation process. Summary of the Invention

[0004] In order to solve the above-mentioned technical defects existing in the prior art, the purpose of the present invention is to provide a vertical circulation system and operation method for railway operating devices. The circulation system can drive multiple operating devices to perform vertical circulation movements, and can achieve that during the continuous advancement of the engineering work vehicle, the internal operating devices remain relatively stationary with the railway line for a certain period of time and complete related maintenance operations.

[0005] Certain connecting mechanisms are added to small machines to upgrade the small machines to corresponding operating devices, and then the operating devices are driven to perform circulating motion in the engineering operation frame by the vertical circulation system of the railway operating device described in the present invention. During the continuous advancement of the circulating frame, since the circulation system is always performing circulating motion in the front-rear direction, the operating device is fixed to the railway line and relatively stationary for a period of time, and the corresponding line maintenance operations can be completed during this period of time.

[0025] In any of the above solutions, preferably, the lower support mechanism includes a left support plate and a right support plate. When the operating device performs relevant maintenance operations, the support wheels contact the support surface to provide vertical support.

[0026] In any of the above schemes, it is preferred that the left support plate and the right support plate have a structure that is narrow at the front and rear ends and wide in the middle, so as to ensure that vertical support can be provided for the operating device when operating on a curved railway line.

[0027] In any of the above schemes, it is preferred that the vertical lifting mechanism includes two sets of symmetrically arranged lifting mechanisms, and each set of the lifting mechanisms includes a support plate, a lifting rail, a horizontal support guide structure, a driving device and a movable support plate.

[0028] In any of the above solutions, it is preferred that the support plate is fixedly mounted on the engineering vehicle frame for installing the lifting rail.

[0029] In any of the above schemes, it is preferred that the horizontal support guide structure is arranged below the lifting track, and when the working device enters the vertical lifting mechanism from the lower support mechanism, the horizontal support guide mechanism provides horizontal movement guidance and vertical support for the working device.

[0030] In any of the above solutions, it is preferred that the driving device is arranged in the middle part of the lifting track.

[0031] In any of the above solutions, preferably, the driving device includes a roller chain, a sprocket, a drive motor, a support block, and a chain track.

[0032] In any of the above schemes, it is preferred that a roller chain passes through a chain track on the side of the support block that supports the working device, thereby ensuring that the chain does not collapse or deform during the lifting process of supporting the working device.

[0033] In any of the above solutions, it is preferred that the upper horizontal conveying mechanism includes a supporting rail, a chain, a scraper, a transmission shaft and a drive motor.

[0034] In any of the above schemes, it is preferred that the front and rear ends of the support track are respectively connected to the steering connection mechanism above the vertical landing mechanism and the vertical lifting mechanism. After the vertical lifting mechanism lifts the working device to the top, it enters the support track horizontally, and the working device rolls on the track through the support wheels.

[0035] In any of the above solutions, preferably, the drive motor drives the chain to rotate cyclically via the transmission shaft, and the scraper on the chain drives the working device to move from the rear end to the front end of the support rail. By adjusting the speed of the drive motor, the horizontal transmission speed of the working device can be controlled.

[0036] In any of the above solutions, preferably, the steering connection mechanism includes a support seat, a sliding plate and a telescopic cylinder.

[0037] In any of the above solutions, it is preferred that the support seat includes two parts, each part includes a connecting plate and a supporting pulley; the two parts are arranged opposite to each other, and the supporting pulley is installed on the opposite surface of the connecting plate.

[0038] In any of the above schemes, it is preferred that the connecting plate is fixedly mounted on the working vehicle frame, wherein one end of the connecting plate is also connected to the upper water conveying mechanism support rail to keep the upper surface on the same plane.

[0040] In any of the above solutions, preferably, one side of the sliding plate is connected to the telescopic cylinder, and the telescopic cylinder drives the sliding plate to slide on the support roller of the support seat.

[0041] When the working device's support rollers are lifted by the vertical lifting mechanism to below the steering and engagement mechanism, the telescopic cylinder retracts, the sliding plate slides away from the support position, and the working device continues to rise to its highest position. Then, the telescopic cylinder extends, the sliding plate slides back to the support position, and the working device descends, its support rollers landing on the sliding plate. The chain scraper of the upper horizontal conveying mechanism carries the working device horizontally. When the working device is horizontally conveyed to the steering and engagement mechanism above the vertical landing mechanism, the telescopic cylinder retracts, the sliding plate slides away from the support position, and the working device falls onto the support seat of the vertical landing mechanism. The support rollers on both sides enter the landing track, and the device begins to descend, driven by the landing mechanism.

[0044] During vertical lifting and lowering, the support block supports the support base, driving the working device to complete the lifting and lowering movement. On the transfer chain conveyor line, the working device is supported by the support base on the roller chain, which drives the working device to complete the conveying. During the raising and lowering of the working device, the support rollers operate on the lifting and lowering tracks to ensure the stability of the lifting and lowering process. During the horizontal conveying of the working device on the lower working support mechanism and the upper horizontal conveying mechanism, the support rollers provide vertical support.

[0045] A second aspect of the present invention provides an operating process of a vertical circulation system of a railway operating device, which comprises the following steps:

[0046] Step A: During high-speed operation of the engineering vehicle: fix the operating device on the frame of the engineering vehicle;

[0047] Step B: Operation preparation stage: Arriving at the operation location, the engineering operation vehicle stops moving forward, and the circulation system drives the operation device to perform a circulation motion inside the engineering operation vehicle;

[0048] Step C: Operation phase: The construction vehicle advances at a low and uniform speed, and the operating device circulates inside the construction vehicle. When the operating device circulates to the bottom of the front end of the construction vehicle, it is moved to the corresponding operation position by the hoisting alignment mechanism. The operating device and the railway line are fixed and remain relatively stationary, and maintenance operations begin. At this time, the lower support mechanism only provides vertical support for the operating device. The construction vehicle continues to advance, and the operating device moves backward relative to the construction vehicle. The time it takes for the operating device to move from the front to the rear relative to the construction vehicle is the time the operating device and the railway line remain relatively stationary, which is also the effective time for the operating device to perform maintenance operations on the railway line. After the operating device reaches the rear end of the construction vehicle, it is lifted by the vertical lifting mechanism for another cycle until the operation of the entire line is completed.

[0049] Step D: Vehicle collection phase: After the operation is completed, the operating device and the engineering vehicle are fixed and driven out of the operation area at high speed.

[0050] The vertical circulation system for railway operating devices of the present invention has the following advantages and effects compared with the prior art:

[0051] 1. This vertical circulation system drives the working device in a circular motion within the continuously advancing construction vehicle. When the working device is positioned below the construction vehicle frame, its relative speed relative to the frame is equal to, but in the opposite direction of, the vehicle's forward speed. During this period, the working device remains stationary relative to the railway line. During this stationary phase, the working device can perform maintenance operations on the railway line. This vertical circulation system allows the internal working device to remain stationary relative to the railway line for a specified period of time while the construction vehicle is continuously advancing, allowing it to complete maintenance operations.

[0052] 2. The lifting track, landing track, lifting drive mechanism and landing drive mechanism in the vertical lifting mechanism and vertical landing mechanism are all arranged vertically, with compact structure, high transmission efficiency, and easy installation and arrangement in a small space.

[0053] 3. A steering connection mechanism is installed at the intersection of the vertical lifting mechanism and the vertical landing mechanism with the horizontal conveying mechanism, which is conducive to the smooth and rapid transition of the operating device in the circulation system from vertical lifting to horizontal conveying and from horizontal conveying to vertical landing.

[0054] 4. A transfer chain conveyor line is installed below the vertical landing mechanism. During operation, the chain conveyor line rotates continuously in a cycle, which can promptly transport the operating device that has landed below to the rear so that the next operating device will not collide with the previous operating device when it lands.

[0055] 5. A hoisting and positioning mechanism is arranged above the rear end of the transfer chain conveyor line. When the operating device is transported from the front to the rear by the transfer chain conveyor line, it is lifted by the hoisting and positioning mechanism and moved backward. After moving to the operating position, it is lowered and can be fixed to the railway line and remain stationary.

[0056] 6. The hoisting alignment mechanism is primarily composed of two sets of sliding mechanisms. During the hoisting and sliding operations, the two mechanisms do not interfere with each other. The simultaneous operation of the two sliding mechanisms can greatly improve the efficiency of the hoisting alignment operation.

[0057] 7. The vertical lifting mechanism, vertical lowering mechanism, upper horizontal conveying mechanism and transfer chain conveyor line all adopt a continuous cycle drive mode, which improves the conveying efficiency and facilitates the control of the conveying speed.

[0058] 8. The lower support mechanism is not designed with a drive device. When the working device circulates to the lower support mechanism, the working device is fixed to the railway line through its own mechanism. At this time, the lower support mechanism provides vertical support for it through the support rollers on the working device. The working device moves backward relative to the lower support mechanism while remaining relatively stationary with the railway line to perform relevant maintenance operations on the railway line.

[0059] 9. According to the needs of railway line maintenance, different operating devices are selected to complete different line maintenance. One circulation system can drive multiple operating devices. BRIEF DESCRIPTION OF THE DRAWINGS

The vertical circulation system for railway working devices according to the present invention comprises an engineering working frame 1 and a lower supporting mechanism 5. The lower middle portion of the engineering working frame 1 is supported by the lower supporting mechanism 5. When the working device 9 operates on the railway track, the lower supporting mechanism 5 provides vertical support for the working device. The engineering working frame 1 runs on the rails as the supporting framework of the entire circulation system. The front end of the engineering working frame 1 is fixedly installed with a vertical descending mechanism 2, which vertically transports the working device 9 above the front end of the frame to a lower position. The rear end of the engineering working frame 1 is installed with a vertical lifting mechanism 6, which vertically lifts the working device 9 below the rear end of the frame to an upper position. The upper middle portion of the engineering working frame 1 is installed with an upper horizontal conveying mechanism 7, which lifts the working device 9 at the rear end of the frame by the vertical lifting mechanism 6 and horizontally transports it to the top of the front end of the frame, and then continues the next cycle.

[0080] The engineering operation vehicle frame 1 serves as the supporting frame of the entire circulation system, and wheels are installed at the bottom. During the operation process, the engineering operation vehicle frame moves forward continuously without the need to stop and wait.

[0081] The vertical circulation system of the railway operating device of the present invention is installed in the continuously advancing engineering operation vehicle frame, and can drive the operating device to perform a circular motion. When the operating device moves to the position below the circulation system, the operating device can be fixed to the railway line and remain relatively stationary, and relevant maintenance operations can be performed on the railway line during this process. The present invention can achieve that during the continuous advancement of the engineering operation vehicle, the internal operating device remains relatively stationary with the railway line for a certain period of time and completes relevant maintenance operations.

[0084] In this embodiment, a lifting and positioning mechanism 4 is installed behind the transfer chain line 3 to lift the working device 9 and move it toward the rear end of the frame. After the working device 9 reaches the working position, it is lowered by the lifting and positioning mechanism 4 and fixed to the railway line to remain relatively stationary and start performing related operations on the railway line.

[0085] In this embodiment, a steering connection mechanism 8 is provided at the junction of the vertical landing mechanism 2 and the vertical lifting mechanism 6 and the upper horizontal conveying mechanism 7 to provide support for the working device 9 during the process of the working device 9 changing from vertical upward movement to horizontal movement and from horizontal movement to vertical downward movement.

[0087] In this embodiment, the support plate 2 - 1 is fixedly mounted on the engineering vehicle frame 1 and is used for installing the landing track 2 - 2 .

[0088] In this embodiment, the horizontal guide structure 2-3 is arranged below the landing track 2-2. When the working device 9 is dropped from above to below, the horizontal guide structure 2-3 provides horizontal movement guidance for the working device 9.

[0089] In this embodiment, the driving device 2-4 is arranged in the middle part of the landing track 2-2.

[0090] The vertical landing mechanism 2 is mounted at the front end of the construction vehicle frame 1. It vertically transports the working device above the front end of the frame to a lower position. The lower support mechanism 5 is mounted at the lower center of the construction vehicle frame 1. When the working device 9 is working on the railway track, the lower support mechanism 5 provides vertical support for the working device 9.

[0091] like Figure 4 As shown, according to the vertical circulation system of the railway working device of the present invention, Figure 2 Schematic diagram of the structure of the driving device in the embodiment shown.

[0092] In this embodiment, the driving device 2-4 includes a roller chain 2-4-1, a sprocket 2-4-2, a driving motor 2-4-3, a support block 2-4-4 and a chain track 2-4-5.

[0094] In this embodiment, on the side of the support block 2-4-4 that supports the working device 9, the roller chain 2-4-1 passes through the chain track 2-4-5 to ensure that the chain will not collapse or deform during the process of supporting the working device 9 to descend.

During operation, the chain rotates in a circular motion. When the working device 9 descends from above, it lands on the transfer chain conveyor line 3 and is transported backward. The continuous rotation of the chain conveyor line 3 allows the dropped working device 9 to be promptly transported to the rear, preventing the next descending working device 9 from colliding with the previous one.

When the working device 9 enters the vertical lifting mechanism 6 from the lower support mechanism 5, the horizontal support guide structure 6-3 provides horizontal movement guidance and vertical support for the working device 9.

[0112] In this embodiment, the driving device 6-4 is arranged in the middle part of the lifting rail 6-2.

[0113] like Figure 12 As shown, according to the vertical circulation system of the railway working device of the present invention, Figure 10 Schematic diagram of the structure of the driving device in the embodiment shown.

[0114] In this embodiment, the drive device 6-4 includes a roller chain 6-4-1, a sprocket 6-4-2, a drive motor 6-4-3, a support block 6-4-4, and a chain track 6-4-5. Driven by the roller chain 6-4-1, the support block 6-4-4 can perform a cyclic lifting action in the vertical direction, while providing vertical support for the lifting of the working device 9 from bottom to top.

[0115] In this embodiment, on the side of the support block 6-4-4 that supports the working device 9, the roller chain 6-4-1 passes through the chain track 6-4-5 to ensure that the chain will not collapse or deform during the lifting process of supporting the working device 9.

[0116] like Figure 13 As shown, according to the vertical circulation system of the railway working device of the present invention, Figure 1 Schematic diagram of the structure of the upper horizontal conveying mechanism in the embodiment shown.

[0117] In this embodiment, the upper horizontal conveying mechanism 7 includes a support rail 7-1, a chain 7-2, a scraper 7-3, a transmission shaft 7-4 and a drive motor 7-5.

[0118] In this embodiment, the front and rear ends of the support rail 7-1 are respectively connected to the vertical landing mechanism 2 and the steering connection mechanism 8 above the vertical lifting mechanism 6. After the vertical lifting mechanism 6 lifts the working device 9 to the top, it enters the support rail 7-1 horizontally, and the working device 9 rolls on the rail through the support wheel 9-3.

[0119] In this embodiment, the drive motor 7-5 drives the chain 7-2 to rotate in a circular motion via the transmission shaft 7-4, and the scraper 7-3 on the chain 7-2 drives the working device 9 from the rear end to the front end of the support rail 7-1. By adjusting the speed of the drive motor 7-5, the horizontal transmission speed of the working device 9 can be controlled.

[0120] like Figure 14 、 Figure 15 As shown, according to the vertical circulation system of the railway working device of the present invention, Figure 1 A schematic structural diagram of the steering connection mechanism in the illustrated embodiment.

[0121] In this embodiment, the steering connection mechanism 8 includes a support seat, a sliding plate 8-2 and a telescopic cylinder 8-3.

[0122] In this embodiment, the support seat includes two parts, each of which includes a connecting plate 8-1-1 and a supporting pulley 8-1-2; the two parts are arranged relative to each other, and the supporting pulley 8-1-2 is installed on the opposite surface of the connecting plate 8-1-1.

[0123] In this embodiment, the connecting plate 8-1-1 is fixedly mounted on the working frame 1, wherein one end of the connecting plate 8-1-1 is also connected to the upper water conveying mechanism support rail 7-1 to keep the upper surface on the same plane.

[0124] In this embodiment, the sliding plate 8-2 is installed in the middle of the two connecting plates 8-1-1 of the support seat, with the lower surface supported on the supporting pulley 8-1-2 and the upper surface flush with the upper surface of the connecting plate 8-1-1.

[0125] In this embodiment, one side of the sliding plate 8-2 is connected to the telescopic cylinder 8-3, and the telescopic cylinder 8-3 drives the sliding plate 8-2 to slide on the support roller 8-1-2 of the support seat.

[0126] When the working device 9's support rollers 9-3 are lifted by the vertical lifting mechanism 6 to below the steering and connecting mechanism 8, the telescopic cylinder 8-3 retracts, the sliding plate 8-2 slides off the support position, and the working device 9 continues to be lifted to its highest position. Then, the telescopic cylinder 8-3 extends, the sliding plate 8-2 slides back to the support position, and the working device 9 drops. Its support rollers 9-3 fall onto the sliding plate 8-2, and are carried horizontally by the chain scraper 7-3 of the upper horizontal conveying mechanism 7. When the working device 9 is horizontally conveyed to the steering and connecting mechanism 8 above the vertical landing mechanism 2, the telescopic cylinder 8-3 retracts, the sliding plate 8-2 slides off the support position, and the working device 9 falls onto the support base 2-4-4 of the vertical landing mechanism 2. The support rollers 9-3 on both sides enter the landing track 2-2, and the working device 9 begins to descend under the drive of the landing mechanism 2. After the working device's support rollers 9-3 fall and leave the steering and connecting mechanism 8, the telescopic cylinder 8-3 extends, and the sliding plate 8-2 slides back to the support position.

[0127] like Figure 16 、 Figure 17 As shown, according to the vertical circulation system of the railway working device of the present invention, Figure 1 Schematic diagram of the structure of the working device in the embodiment shown.

[0128] In this embodiment, the working device 9 includes a device body 9-1, a support seat 9-2 and a support roller 9-3.

[0129] In this embodiment, the device body 9-1 is a fastener processing device or a rail processing device or a sleeper processing device.

[0130] During vertical lifting and vertical descent, the support block 2-4-4 supports the support seat 9-2, driving the working device 9 to complete the lifting and lowering movement. On the transfer chain conveyor line 3, the working device 9 is supported on the roller chain 3-1 through the support seat 9-2, and the roller chain 3-1 drives the working device 9 to complete the conveying. During the lifting and lowering process of the working device 9, the support roller 9-3 operates in the lifting track 6-2 and the lowering track 2-2 to ensure the stability of the lifting and lowering process. During the horizontal conveying process of the working device 9 on the lower working support mechanism 5 and the upper horizontal conveying mechanism 7, the vertical support is achieved by the support roller 9-3.

[0131] Last read Figure 18 As shown, this is a working flow chart of the vertical circulation system of the railway operating device according to the present invention.

[0132] A second aspect of the present invention provides an operating process of a vertical circulation system of a railway operating device, which comprises the following steps:

[0133] Step A: High-speed operation stage of the engineering vehicle: fix the working device 9 on the engineering vehicle frame 1;

[0134] Step B: Operation preparation stage: Upon reaching the operation position, the engineering vehicle 1 stops moving forward, and the circulation system drives the operation device 9 to perform a circulation motion inside the engineering vehicle 1;

[0135] Step C: Operation phase: The construction vehicle 1 advances at a low and uniform speed, and the operation device 9 circulates inside the construction vehicle 1. When the operation device 9 circulates to the bottom of the front end of the construction vehicle 1, it is moved to the corresponding operation position by the hoisting alignment mechanism 4. The operation device 9 and the railway line are fixed and remain relatively stationary, and maintenance operations begin. At this time, the lower support mechanism only has a vertical support function for the operation device 9. The construction vehicle 1 continues to advance, and the operation device 9 moves backward relative to the construction vehicle 1. The time it takes for the operation device 9 to move from the front to the rear relative to the construction vehicle 1 is the time when the operation device 9 and the railway line are relatively stationary, which is also the effective time for the operation device 9 to perform maintenance operations on the railway line. After the operation device 9 reaches the rear end of the construction vehicle 1, it is lifted by the vertical lifting mechanism 6 for the next cycle until the operation of the entire line is completed.

[0136] Step D: Vehicle collection phase: After the operation is completed, the operation device 9 is fixed to the engineering operation vehicle 1 and drives out of the operation area at high speed.

[0137] As an alternative solution: the vertical lifting mechanism, vertical landing mechanism and transfer chain conveyor line use drive motors. In this technical solution, electric motors, hydraulic motors or pneumatic motors can be used; the vertical landing mechanism and the vertical lifting mechanism both use circulating chains as drive mechanisms, and telescopic cylinders, wire rope winches, reciprocating chain motion mechanisms and other drive mechanisms can also be used; a lower support mechanism is designed to provide vertical support for the operating device during operation, or the operating device itself can be fixedly supported on the railway line, and the lower support mechanism can also be omitted in the entire circulation system; the upper horizontal conveying mechanism uses a chain scraper mechanism for transmission, and can also be transmitted by transmission rollers, chain conveyor lines and other methods; the movable support plate on the vertical landing mechanism is hinged at one end and overlapped on the horizontal guide structure by an elastic hinge method; the movable support plate on the vertical lifting mechanism is hinged at one end and overlapped on the horizontal support guide structure by an elastic hinge method, and other methods can also be used, such as an elastic telescopic structure. As long as it can be squeezed open when the support block passes by, and can be reset to support the operating device after the support block passes, it can be used as the technical solution of the present invention.

[0138] Those skilled in the art will readily appreciate that the vertical circulation system and operating method for railway operating equipment of the present invention encompass any combination of the various components described in this specification. Due to space limitations and to maintain clarity, these combinations are not described in detail here. However, after reading this specification, the scope of the present invention, encompassed by any combination of the various components described herein, will be readily apparent.
