Description

Technical Field

[0001] The present invention relates to the field of railway engineering machinery, and in particular to a railway operating device annular circulation system and an operating method. 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 circular circulation system and operation method for railway operating devices. The circulation system can drive multiple working devices to perform circular circulation motion, 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] By adding a connecting mechanism to a small tool, the tool is upgraded to a corresponding operating device. The circular circulation system for a railway operating device described in the present invention then drives the operating device to circulate within the construction work frame. As the circulating frame continuously advances, the circulating system continuously circulates in a forward and backward direction, allowing the operating device to remain fixed to the railway line and relatively stationary for a period of time, allowing the corresponding line maintenance work to be completed during this period. The circular circulation system and operating method for a railway operating device described in the present invention can significantly reduce the labor required for line maintenance operations, reducing labor costs while improving operational safety.

[0006] In order to achieve the above-mentioned design objectives, the scheme adopted by the present invention is as follows:

[0007] The first aspect of the present invention provides a circular circulation system for railway working devices, including an engineering working frame and a lower supporting mechanism, wherein the middle lower portion of the engineering working frame is supported by the lower supporting mechanism, and when the working device operates on the railway track, the lower supporting mechanism has a vertical supporting effect on the working device; the engineering working frame runs on the rails as the supporting frame of the entire circulation system, and the front end of the engineering working frame is fixedly installed with a circular descending mechanism, which is used to smoothly transport the working device above the front end of the frame to a lower position through circular transportation; the rear end of the engineering working frame is installed with a circular lifting mechanism, which is used to smoothly lift the working device below the rear end of the frame to an upper position through circular transportation; an upper horizontal conveying mechanism is installed above the middle of the engineering working frame 1, which lifts the working device at the rear end of the bracket by the circular lifting mechanism and horizontally transports it to the top of the front end of the frame, and then continues the next cycle.

[0008] Preferably, a positioning mechanism is fixedly installed below the front end of the engineering work frame. When the working device descends from above the front end to below, the positioning mechanism drives the working device to move backward.

[0009] In any of the above solutions, it is preferred that the annular landing mechanism includes a support plate, an annular landing track and a driving device, and the support plate is fixedly mounted on the engineering vehicle frame for mounting the annular landing track.

[0010] In any of the above schemes, it is preferred that the annular landing track includes an inner track and an outer track, and the two tracks are staggered with each other in a direction perpendicular to the support plate. The inner track provides guidance and support for the short-axis support wheels of the working device, and the outer track provides guidance and support for the long-axis support wheels of the working device.

[0011] In any of the above schemes, it is preferred that the radius R of the inner track and the outer track are the same, the horizontal offset L of the track center and the center distance M of the rolling wheels of the working device are equal, to ensure that the working device does not swing during the circular landing process.

[0013] In any of the above solutions, preferably, the movable panel is arranged on the inner track, with one end hinged to the inner track and the other end overlapped on the inner track.

[0014] When a long-axis support wheel of the working device moves along the outer track to the staggered position, the movable plate can be pushed upward; when the long-axis support wheel passes the staggered position a, the movable plate will automatically fall down and continue to provide support and guidance for the short-axis support wheel on the inner track.

[0015] In any of the above solutions, preferably, the driving device includes a landing wheel, a driving shaft and a driving motor. The driving shaft can transmit the rotational motion of the driving motor to the landing wheel.

[0016] In any of the above solutions, it is preferred that a plurality of landing teeth are evenly distributed on the outer edge of the landing wheel, and their function is to provide supporting force during the landing process of the operating device.

[0017] In any of the above solutions, it is preferred that the support plate, the inner landing track, the outer landing track and the landing wheels are symmetrically arranged on both sides of the cyclic motion trajectory of the working device.

[0018] In any of the above schemes, it is preferred that a spacing corresponding to the width of the working device is left between the landing tracks (the landing tracks include an inner landing track and an outer landing track) symmetrically arranged on both sides of the cyclic motion trajectory of the working device, so that the working device will not interfere with the annular landing mechanism during the circulation process.

[0019] In any of the above schemes, it is preferred that the lower support mechanism includes a left support plate and a right support plate. When the operating device performs relevant maintenance operations, the long-axis support wheels and the short-axis support wheels contact the support surfaces of the left support plate and the right support plate to provide vertical support.

[0020] 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.

[0021] In any of the above solutions, preferably, the annular lifting mechanism includes a support plate, a lifting rail and a lifting mechanism driving device.

[0022] 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.

[0023] In any of the above schemes, it is preferred that the lifting track includes an inner track of the lifting mechanism and an outer track of the lifting mechanism, and the two tracks are staggered with each other in a direction perpendicular to the support plate. The inner track of the lifting mechanism provides guidance and support for the short-axis support wheels of the working device, and the outer track of the lifting mechanism provides guidance and support for the long-axis support wheels of the working device.

[0024] In any of the above schemes, it is preferred that the radius R1 of the inner track of the lifting mechanism and the outer track of the lifting mechanism are the same, and the horizontal offset L1 of the track center is equal to the center distance M1 of the rolling wheel of the working device, to ensure that the working device does not swing during the circular lifting process.

[0025] In any of the above solutions, preferably, a lifting mechanism movable plate is provided at the intersecting position of the lifting mechanism inner track and the lifting mechanism outer track.

[0026] In any of the above solutions, preferably, the lifting mechanism movable plate is arranged on the inner track of the lifting mechanism, with one end hinged to the inner track of the lifting mechanism and the other end overlapped on the outer track of the lifting mechanism.

[0027] When a long-axis support wheel of the operating device moves to the staggered position along the outer track of the lifting mechanism, the movable plate of the lifting mechanism can be pushed upward; when the long-axis support wheel passes the staggered position, the movable plate of the lifting mechanism will automatically fall down and continue to provide support and guidance for the short-axis support wheel on the inner track of the lifting mechanism.

[0028] In any of the above solutions, preferably, the lifting mechanism driving device includes a lifting wheel, a lifting mechanism driving shaft and a lifting mechanism driving motor, and the lifting mechanism driving shaft can transmit the rotational motion of the lifting mechanism driving motor to the lifting wheel.

[0029] In any of the above solutions, it is preferred that a plurality of lifting teeth are evenly distributed on the outer edge of the lifting wheel, and their function is to provide lifting force during the lifting process of the working device.

[0030] In any of the above schemes, it is preferred that the support plate, lifting rail and lifting wheel are symmetrically arranged on both sides of the cyclic motion trajectory of the working device; a spacing corresponding to the width of the working device is left between the lifting rails symmetrically arranged on both sides of the motion trajectory of the working device, so that the working device will not interfere with the annular lifting mechanism during the circulation process.

[0031] In any of the above schemes, it is preferred that the upper horizontal conveying mechanism includes a supporting rail, a chain, a scraper, a transmission shaft and a conveying mechanism drive motor.

[0032] In any of the above schemes, it is preferred that the front and rear ends of the support track are respectively connected to the upper part of the annular landing mechanism and the annular lifting mechanism. After the working device is lifted to the upper part by the annular lifting mechanism, it can enter the support track horizontally, and the working device rolls on the track through the long-axis support wheels and the short-axis support wheels.

[0033] The conveyor mechanism's drive motor drives the chain through a drive shaft, which in turn rotates the chain. The scraper on the chain drives the working device from the rear end of the support track to the front end. By adjusting the speed of the drive motor, the robot's horizontal transmission speed can be controlled.

[0034] In any of the above solutions, preferably, the alignment mechanism includes two sets of symmetrically installed pushing mechanisms, and each set of pushing mechanisms includes a bracket, a slide rail assembly, a telescopic seat and a telescopic cylinder.

[0035] In any of the above solutions, preferably, the bracket is installed on the engineering work vehicle frame and is located below the annular landing mechanism and in front of the lower support mechanism.

[0036] In any of the above solutions, preferably, the telescopic seat is connected to the bracket through a slide rail assembly and can slide under the drive of the telescopic cylinder.

[0037] In any of the above solutions, preferably, a spring and a slide groove structure are provided inside the telescopic seat so as to be able to perform a telescopic action.

[0038] As the work device descends from the ring-shaped lowering mechanism, the telescopic cylinder extends, pushing the device toward the rear of the construction vehicle frame and simultaneously moving it backward relative to the railway track. Once in the working position, the telescopic cylinder stops, securing the device and the track and maintaining relative stillness, allowing maintenance work to begin.

[0039] A second aspect of the present invention provides an operating process of a railway operating device annular circulation system, which includes the following steps:

[0040] Step A: During high-speed operation of the engineering vehicle: fix the operating device on the frame of the engineering vehicle;

[0041] 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;

[0042] Step C: Operation phase: The engineering work vehicle advances at a low and uniform speed, and the operating device circulates inside the engineering work vehicle. When the operating device circulates to the bottom of the front end of the vehicle frame, it is moved to the corresponding operating position by the positioning 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 engineering work vehicle continues to advance, and the operating device moves backward relative to the work vehicle frame. The time it takes for the operating device to move from the front to the rear relative to the work vehicle frame 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 work vehicle frame, it is lifted by the circular lifting mechanism for another cycle until the operation of the entire line is completed.

[0043] 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.

[0044] Compared with the prior art, the railway operating device annular circulation system of the present invention has the following advantages and effects:

[0045] 1. The circular 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 track. During this stationary phase, the working device can perform maintenance operations on the railway track. This circular circulation system allows the internal working device to remain stationary relative to the railway track for a specified period of time while the construction vehicle is continuously advancing, allowing it to complete maintenance operations.

[0046] 2. The lifting track and the lowering track in the ring lifting mechanism and the ring lowering mechanism are both ring tracks, and adopt special track and connection structure, so that the working device can be transported smoothly and stably in the mechanism.

[0047] 3. The ring lifting mechanism, ring lowering mechanism and upper horizontal conveying mechanism all adopt continuous cycle drive, which improves the conveying efficiency and facilitates the control of conveying rhythm.

[0048] 4. 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.

[0049] 5. The alignment mechanism is located at the front end of the lower support structure. When the working device descends from above, it drives the working device backward on the lower support structure relative to the working frame, while also maintaining a relatively slow backward speed relative to the railway track. Once the working device reaches its position, the alignment mechanism stops, and the working device remains stationary relative to the railway track.

[0050] 6. According to the needs of railway line maintenance, different operating devices are selected to complete different line maintenance. The circulation system described in the present invention can drive multiple operating devices. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] To more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other embodiments can be derived from these drawings without inventive effort.

[0067] like Figure 1 The figure shows a schematic structural diagram of a preferred embodiment of a circular circulation system for railway working devices according to the present invention. The circular circulation system for railway working devices according to the present invention comprises an engineering working frame 1 and a lower supporting mechanism 3. The lower middle portion of the engineering working frame 1 is supported by the lower supporting mechanism 3. When the working device 7 operates on the railway track, the lower supporting mechanism 3 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 circular lowering mechanism 2, which transports the working device 7 above the front end of the frame to a lower position through circular conveying. The rear end of the engineering working frame 1 is installed with a circular lifting mechanism 4, which lifts the working device 7 below the rear end of the frame to an upper position through circular conveying. The upper middle portion of the engineering working frame 1 is installed with an upper horizontal conveying mechanism 5, which lifts the working device 7 at the rear end of the frame by the circular lifting mechanism 4 and transports it horizontally to the front end of the frame, and then continues the next cycle.

[0068] In this embodiment, a positioning mechanism 6 is fixedly installed below the front end of the engineering work frame 1. When the working device 7 descends from the top of the front end to the bottom, the positioning mechanism 6 drives the working device 7 to move backward. After reaching the working position, the working device 7 is fixed relatively still to the railway line and starts to perform related operations on the railway line.

[0069] like Figure 2 、 Figure 3 As shown, the railway operation device ring circulation system according to the present invention Figure 1 The schematic diagram of the structure of the annular landing mechanism in the preferred embodiment is shown.

[0070] In this embodiment, the annular landing mechanism 2 includes a support plate 2-1, an annular landing track and a driving device. The support plate 2-1 is fixedly mounted on the engineering vehicle frame 1 and is used to install the annular landing track.

[0071] In this embodiment, the annular landing track includes an inner track 2-2 and an outer track 2-3. The two tracks are staggered with each other in a direction perpendicular to the support plate 2-1. The inner track 2-2 provides guidance and support for the short-axis support wheel 7-2 of the working device, and the outer track 2-3 provides guidance and support for the long-axis support wheel 7-1 of the working device.

[0072] like Figure 4-6 As shown, the railway operation device ring circulation system according to the present invention Figure 2 Schematic diagram of the landing track of the annular landing mechanism in the embodiment shown.

[0073] In this embodiment, the radius R of the inner track 2-2 and the outer track 2-3 are the same, and the horizontal offset L of the track center is equal to the center distance M of the rolling wheels of the working device, ensuring that the working device does not swing during the circular landing process.

[0074] In this embodiment, movable plates 2-8 are provided on the inner rail 2-2 and the outer rail 2-3 at positions staggered from each other in a direction perpendicular to the support plate 2-1.

[0075] In this embodiment, the movable panel 2-8 is arranged on the inner track 2-2, with one end hinged to the inner track 2-2 and the other end overlapped on the inner track 2-2.

[0076] When a long-axis support wheel 7-1 of the operating device 7 moves to the staggered position along the outer track 2-3, the movable plate 7 can be pushed upward; when the long-axis support wheel 7-1 passes the staggered position а, the movable plate 2-8 will automatically fall down and continue to provide support and guidance for the short-axis support wheel 7-2 on the inner track 2-2.

[0077] In this embodiment, the driving device includes a landing wheel 2-4, a driving shaft 2-5 and a driving motor 2-6. The driving shaft 2-5 can transmit the rotational motion of the driving motor 2-6 to the landing wheel 2-4.

[0078] In this embodiment, a plurality of landing teeth 2-7 are evenly distributed on the outer edge of the landing wheel 2-4, and their function is to provide supporting force during the landing process of the operating device 7.

[0079] In this embodiment, the support plate 2 - 1 , the inner landing track 2 - 2 , the outer landing track 2 - 3 and the landing wheel 2 - 4 are symmetrically arranged on both sides of the circular motion trajectory of the working device 7 .

[0080] In this embodiment, the landing tracks (the landing tracks include an inner landing track 2-2 and an outer landing track 2-3) symmetrically arranged on both sides of the cyclic motion trajectory of the working device 7 have a spacing corresponding to the width of the working device 7 between the inner landing track 2-2 and the outer landing track 2-3, so that the working device 7 will not interfere with the annular landing mechanism 2 during the circulation process.

[0081] See next Figure 7 As shown, the railway operation device ring circulation system according to the present invention Figure 1 Schematic diagram of the structure of the lower support mechanism in the illustrated embodiment.

[0082] In this embodiment, the lower support mechanism 3 includes a left support plate 3-1 and a right support plate 3-2. When the working device 7 performs relevant maintenance operations, the long-axis support wheel 7-1 and the short-axis support wheel 7-2 contact the support surfaces of the left support plate 3-1 and the right support plate 3-2 to provide vertical support.

[0083] In this embodiment, the left support plate 3-1 and the right support plate 3-2 are narrow at the front and rear ends and wide in the middle, so as to provide vertical support for the operating device 7 when operating on a curved railway line.

[0084] like Figure 8 、 Figure 9 As shown, the railway operation device ring circulation system according to the present invention Figure 1 A schematic structural diagram of the annular lifting mechanism in the illustrated embodiment.

[0085] In this embodiment, the annular lifting mechanism 4 includes a support plate 4 - 1 , a lifting rail and a lifting mechanism driving device.

[0086] In this embodiment, the support plate 4 - 1 is fixedly mounted on the engineering vehicle frame 1 and is used for installing the lifting rail.

[0087] In this embodiment, the lifting track includes an inner track 4-2 of the lifting mechanism and an outer track 4-3 of the lifting mechanism. The two tracks are staggered with each other in a direction perpendicular to the support plate. The inner track 4-2 of the lifting mechanism provides guidance and support for the short-axis support wheel 7-2 of the working device, and the outer track 4-3 of the lifting mechanism provides guidance and support for the long-axis support wheel 7-1 of the working device.

[0088] In this embodiment, the lifting mechanism driving device includes a lifting wheel 4-4, a lifting mechanism driving shaft 4-5 and a lifting mechanism driving motor 4-6. The lifting mechanism driving shaft 4-5 can transmit the rotational motion of the lifting mechanism driving motor 4-6 to the lifting wheel 4-4.

[0089] In this embodiment, a plurality of lifting teeth 4 - 7 are evenly distributed on the outer edge of the lifting wheel 4 - 4 , and their function is to provide lifting force during the lifting process of the working device 7 .

[0090] In this embodiment, the support plate 4-1, lifting rail and lifting wheel 4-4 are symmetrically arranged on both sides of the circular motion trajectory of the working device 7; a spacing corresponding to the width of the working device 7 is left between the lifting rails symmetrically arranged on both sides of the motion trajectory of the working device, so that the working device 7 will not interfere with the annular lifting mechanism 4 during the circulation process.

[0091] Depending on the needs of railway line maintenance, different operating devices 7 can be selected within the circulation mechanism to complete different line maintenance tasks. A single circulation system can drive multiple operating devices. The operating device 7 only needs to have structural dimensions that match those of the circulation system. Specifically, the dimensions of the short-axis support wheels 7-2 and long-axis support wheels 7-1 must match the inner guide rails 2-2 and outer guide rails 2-3 of the annular lowering mechanism 2, as well as the inner lift rails 4-2 and outer lift rails 4-3 of the annular lift mechanism 3. This operating device 7 can then be driven by the circulation system to perform a cyclic motion within the engineering work frame 1, remaining stationary relative to the railway line on the lower support mechanism 3, thus completing the corresponding line maintenance tasks.

[0092] like Figure 10-12 As shown, the railway operation device ring circulation system according to the present invention Figure 1 Schematic diagram of the lifting track of the lifting mechanism in the illustrated embodiment.

[0093] In this embodiment, the radius R1 of the inner track 4-2 of the lifting mechanism and the outer track 4-3 of the lifting mechanism are the same, and the horizontal offset L1 of the track center is equal to the center distance M1 of the rolling wheel of the working device, ensuring that the working device does not swing during the circular lifting process.

[0094] In this embodiment, a lifting mechanism movable plate 4-8 is provided at the intersecting position of the lifting mechanism inner rail 4-2 and the lifting mechanism outer rail 4-3.

[0095] In this embodiment, the lifting mechanism movable plate 4-8 is arranged on the inner track 4-2 of the lifting mechanism, one end is hinged to the inner track 4-2 of the lifting mechanism, and the other end is overlapped on the outer track 4-3 of the lifting mechanism.

[0096] When a long-axis support wheel 7-1 of the operating device 7 moves to the staggered position along the outer track 4-3 of the lifting mechanism, the movable plate 4-8 of the lifting mechanism can be pushed upward; when the long-axis support wheel 7-1 passes the staggered position, the movable plate 4-8 of the lifting mechanism will automatically fall down and continue to provide support and guidance for the short-axis support wheel 7-2 of the inner track 4-2 of the lifting mechanism.

[0097] like Figure 13 As shown, the railway operation device ring circulation system according to the present invention Figure 1 Schematic diagram of the structure of the upper horizontal conveying mechanism in the embodiment shown.

[0098] In this embodiment, the upper horizontal conveying mechanism 5 includes a support rail 5-1, a chain 5-2, a scraper 5-3, a transmission shaft 5-4 and a conveying mechanism drive motor 5-5.

[0099] In this embodiment, the front and rear ends of the support track 5-1 are respectively connected to the upper part of the annular landing mechanism 2 and the annular lifting mechanism 4. After the working device 7 is lifted to the upper part by the annular lifting mechanism 4, it can enter the support track 5-1 horizontally, and the working device 7 rolls on the track through the long-axis support wheel 7-1 and the short-axis support wheel 7-2.

[0100] The conveying mechanism drive motor 5-5 drives the chain 5-2 to rotate in a circular motion through the transmission shaft 5-4. The scraper 5-3 on the chain 5-2 drives the working device from the rear end to the front end of the support track 5-1. By adjusting the speed of the drive motor 5-5, the horizontal transmission speed of the robot can be controlled.

[0101] like Figure 14 As shown, the railway operation device ring circulation system according to the present invention Figure 1 A schematic structural diagram of the alignment mechanism in the illustrated embodiment.

[0102] In this embodiment, the alignment mechanism 6 includes two sets of pushing mechanisms that are symmetrically installed, and each set of pushing mechanisms includes a bracket 6-1, a slide rail assembly 6-2, a telescopic seat 6-3 and a telescopic cylinder 6-4.

[0103] In this embodiment, the bracket 6 - 1 is installed on the engineering vehicle frame 1 , and is located below the annular landing mechanism 2 and in front of the lower support mechanism 3 .

[0104] In this embodiment, the telescopic seat 6-3 is connected to the bracket 6-1 through the slide rail assembly 6-2 and can slide under the drive of the telescopic cylinder 6-4.

[0105] In this embodiment, a spring 6-3-1 and a slide groove structure 6-3-2 are provided inside the telescopic seat 6-3, which can perform telescopic movements.

[0106] As the working device 7 descends from above the annular lowering mechanism 2 to below, the telescopic cylinder 6-4 extends, pushing the working device 7 toward the rear of the construction vehicle frame 1. Simultaneously, the working device 7 moves rearward relative to the railway track. Once in the working position, the telescopic cylinder 6-4 stops, securing the working device 7 relative to the railway track and maintaining it stationary. Maintenance work begins.

[0107] Last read Figure 15 FIG. 2 is a flowchart of the working process of the circular circulation system of the railway operation device according to the present invention.

[0108] A second aspect of the present invention provides an operating process of a railway operating device annular circulation system, which includes the following steps:

[0109] Step A: High-speed operation stage of the engineering vehicle: fix the operating device 7 on the engineering vehicle frame 1;

[0110] 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 7 to perform a circulation motion inside the engineering vehicle 1;

[0111] Step C: Operation phase: the engineering work vehicle 1 moves forward at a low and uniform speed, and the operation device 7 circulates inside the engineering work vehicle 1. When the operation device 7 circulates to the bottom of the front end of the vehicle frame, it is moved to the corresponding operation position by the positioning mechanism 6. The operation device 7 and the railway line are fixed and remain relatively stationary, and maintenance work begins. At this time, the lower support mechanism 3 only has a vertical support function for the operation device 7. The engineering work vehicle 1 continues to move forward, and the operation device 7 moves backward relative to the operation vehicle frame. The time it takes for the operation device 7 to move from the front end to the rear end relative to the operation vehicle frame is the time when the operation device 7 and the railway line are relatively stationary, and it is also the effective time for the operation device 7 to perform maintenance work on the railway line. After the operation device 7 reaches the rear end of the operation vehicle frame, it is lifted by the annular lifting mechanism 4 for the next cycle until the operation of the entire line is completed.

[0112] Step D: Vehicle collection phase: The operation is completed, the operation device 7 is fixed to the engineering operation vehicle 1, and it drives out of the operation area at high speed.

[0113] As an alternative: the annular lowering mechanism and the annular lifting mechanism are both driven by electric motors, and can also be replaced by driving devices such as hydraulic motors; the alignment mechanism is driven by a telescopic cylinder, and can also be replaced by motion mechanisms such as gear racks, screw transmission mechanisms, etc.; a lower support mechanism is designed to provide vertical support for the operating device during operation, and the operating device itself can also 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 adopts a chain scraper mechanism for transmission, and can also be transmitted by transmission rollers, chain conveyor lines, etc.

[0114] Those skilled in the art will readily appreciate that the railway operating device annular circulation system and operating method 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.
