[0042] In the embodiment of the present application, the support plate 2 is movably connected to the base 1, the traction mechanism 3 is arranged on the base 1 and connected to the support plate 2, and the traction mechanism 3 is used to drive the support plate 2 to move relative to the base 1 so that the support plate 2 switches between the first position and the second position; wherein, when the support plate 2 is in the first position, the support plate 2 is located in the base 1, and when the support plate 2 is in the second position, the support plate 2 is at least partially suitable for extending into the bottom of the vehicle to be repaired to carry the repair parts of the vehicle. In this way, the transport and replacement of the repair parts are carried out by extending the retractable support plate 2 into the bottom of the vehicle, thereby reducing the input of manpower and material resources and improving the maintenance efficiency; at the same time, the safety during maintenance is improved.

[0043] In specific applications, the base 1 is used to support components or mechanisms installed on the base 1. The base 1 can adopt a frame structure. The base 1 can be welded from multiple sections of square tubes, or it can be bolted from multiple sections of square tubes. Technical personnel in this field can choose according to actual needs, and the embodiments of the present application do not limit this.

[0044] In a specific application, the traction mechanism 3 drives the support plate 2 to move relative to the base 1, so that the support plate 2 can be extended into the bottom of the vehicle to be repaired, or retracted into the base 1, so that the maintenance parts can be moved from the bottom of the vehicle where it is inconvenient to repair to a wider vehicle operation and maintenance device.

[0045] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the four corners of the bottom of the base 1 are provided with adjustable lifting parts. When the ground or workbench on which the base 1 is located is uneven, the adjustable lifting parts at the four corners can be adjusted to make the bearing surface of the support plate 2 in the base 1 in a horizontal state, thereby ensuring the balance and safety of the bearing mechanism or maintenance parts.

[0046] Understandably, referring to Figure 2 The support plate 2 is connected to the base 1. When the support plate 2 is in the first position, the support plate 2 is located in the base 1. Therefore, when the support plate 2 carries vehicle maintenance parts, the base 1 can bear the weight of the support plate 2 and the vehicle maintenance parts to ensure safety during maintenance.

[0047] Understandably, referring to Figure 1 When the support plate 2 is in the second position, the support plate 2 is at least partially suitable for extending into the bottom of the vehicle to be repaired (not shown in the figure), so that after the repair parts of the vehicle are removed, they are placed on the support plate 2, thereby carrying the repair parts of the vehicle without human support, thereby improving the repair efficiency and safety during repair.

[0048] Taking rail vehicle maintenance as an example, during maintenance, the vehicle operation and maintenance device is placed next to the vehicle track beam 4 at the part to be repaired, the support plate 2 is extended into the bottom of the vehicle to be repaired, that is, the second position, the disassembled maintenance parts are placed on the support plate 2, and then the support plate 2 is recovered to the base 1, that is, the first position, to facilitate the maintenance of the maintenance parts, or the maintenance parts are transported to the maintenance workshop for further maintenance through the mobile mechanism.

[0049] Optionally, refer to Figure 3The traction mechanism 3 includes a first driving member 31, a transmission member 32 and a traction plate 33. The transmission member 32 is movably connected to the base 1, the traction plate 33 is fixedly connected to the transmission member 32, and the support plate 2 is connected to the traction plate 33; the first driving member 31 is connected to the transmission member 32, and is used to drive the transmission member 32 to move, so that the traction plate 33 drives the support plate 2 to switch between the first position and the second position.

[0050] In the embodiment of the present application, the transmission member 32 transmits the driving force of the first driving member 31 to the traction plate 33, thereby driving the support plate 2 to switch between the first position and the second position. Thus, the support plate 2 can automatically switch between the first position and the second position without the need for manpower to transfer, thereby improving maintenance efficiency.

[0051] In specific applications, refer to Figure 3 The traction mechanism 3 is arranged on the base 1, and the first driving member 31 is connected to the transmission member 32, driving the transmission member 32 to move, thereby driving the traction plate 33 fixedly connected to the driving member 32 to move, and then can drive the support plate 2 to reciprocate between the first position and the second position.

[0052] It can be understood that the specific transmission mode of the transmission member 3 can be belt transmission, worm gear transmission, rack and pinion transmission, gear set transmission and other transmission modes. Those skilled in the art can select according to actual needs, and the embodiments of the present application do not limit this.

[0053] Optionally, refer to Figure 3 The transmission member 32 includes a first rotating shaft 321, a second rotating shaft 322 and a transmission belt 323. The first rotating shaft 321 and the second rotating shaft 322 are both rotatably connected to the base 1. The first rotating shaft 321 and the second rotating shaft 322 are arranged at intervals along the moving direction of the support plate 2. The transmission belt 323 is sleeved on the first rotating shaft 321 and the second rotating shaft 322. The traction plate 33 is fixedly connected to the transmission belt 323. The first driving member 31 is connected to the first rotating shaft 321 or the second rotating shaft 322.

[0054] In the embodiment of the present application, the transmission member 32 adopts a belt drive structure. The first rotating shaft 321 and the second rotating shaft 322 arranged at both ends of the base 1 drive the traction plate 33 and the support plate 2 under the drive of the first driving member 31, so that the transmission member 32 has a higher transmission efficiency.

[0055] In a specific application, when the transmission mode of the transmission member 32 is belt transmission, a first rotating shaft 321 and a second rotating shaft 322 are provided at both ends of the top of the base 1, and a transmission belt 323 is sleeved on the first rotating shaft 321 and the second rotating shaft 322. The traction plate 33 is fixedly connected to the transmission belt 323, and the first driving member 31 is connected to the first rotating shaft 321 or the second rotating shaft 322. Among them, of the first rotating shaft 321 and the second rotating shaft 322, the one connected to the first driving member 31 is the driving shaft, and the other is the driven shaft. The driving shaft rotates under the drive of the first driving member 31, and the movement of the transmission belt 323 drives the driven shaft to rotate, thereby realizing the reciprocating motion of the traction plate 33 connected to the transmission belt between the first position and the second position.

[0056] It can be understood that a bearing seat is provided on the base 1, and the first rotating shaft 321 and the second rotating shaft 322 are inserted into the corresponding bearing seats. The first rotating shaft 321 or the second rotating shaft 322 and the bearing seat are positioned by a shoulder, thereby improving the transmission efficiency and transmission stability.

[0057] Optionally, refer to Figure 3 The first rotating shaft 321 and the second rotating shaft 322 are provided with pulleys 324, and the transmission belt 323 is a synchronous belt, which is meshed with the pulleys.

[0058] In the embodiment of the present application, the transmission member 32 is a synchronous belt transmission, the first rotating shaft 321 and the second rotating shaft 322 are provided with pulleys 324, the transmission belt 323 is a synchronous belt, and the synchronous belt is meshed with the pulleys. In this way, the transmission is more stable and the noise is smaller; at the same time, the synchronous belt transmission can be overload protected.

[0059] In a specific application, the transmission belt 323 is a synchronous belt, and the first rotating shaft 321 and the second rotating shaft 322 are provided with a pulley 324, and the synchronous belt and the pulley 324 are meshed to form a synchronous belt transmission. The pulley 324 is locked with the first rotating shaft 321 or the second rotating shaft 322 by a screw, and under the drive of the first driving member 31, the pulley 324 drives the synchronous belt to move, and then drives the traction plate 33 and the support plate 2 fixed on the synchronous belt to move, so as to realize the position switching of the support plate 2 between the first position and the second position.

[0060] Optionally, refer to Figure 3 The traction mechanism 3 also includes a sensing member 34 and a controller. The sensing member 34 is arranged on the base 1 and is used to sense the relative position of the support plate 2 and the base 1. The controller is connected to the sensing member 34 and the first driving member 31 and is used to control the operation of the first driving member 31 based on the sensing signal of the sensing member 34.

[0061] In the embodiment of the present application, a sensing member 34 for sensing the relative position of the support plate 2 and the base 1 is also provided on the base 1. The controller connects the sensing member 34 and the first driving member 31, thereby controlling the operation of the first driving member 31 according to the sensing signal of the sensing member 34, and then controlling the operation of the support plate 2, so that the support plate 2 stops when it reaches the preset first position and the second position, thereby eliminating the steps of human operation and improving the overall maintenance efficiency.

[0062] It can be understood that the sensing element 34 can be a pressure sensor, an infrared sensor, a visual sensor, etc., and those skilled in the art can select them according to actual needs, and the embodiments of the present application do not limit this.

[0063] In specific applications, refer to Figure 3 The sensing member 34 is respectively arranged beside the first rotating shaft 321 and beside the second rotating shaft 322. The first driving member 31 drives the first rotating shaft 321. When the support plate 2 moves from the first position to the second position, the sensing member 34 located beside the first rotating shaft 321 senses the position of the support plate 2, the first driving member 31 stops running, and the support plate 2 stops at the second position; similarly, when the support plate 2 moves from the second position to the first position, the sensing member 34 located beside the second rotating shaft 322 senses the position of the support plate 2, the first driving member 31 stops running, and the support plate 2 stops at the first position.

[0064] The following description will be made by taking the sensing element 34 as a pressure sensor as an example. Figure 3 When the support plate 2 moves from the second position to the first position, the sensing member 34 is in at least partial contact with the traction plate 33, thereby transmitting the sensing signal to the controller, and the controller controls the first driving member 31 to stop running, so that the driving shaft (first rotating shaft 321) and the transmission belt 323 stop rotating, and then the traction plate 33 fixedly connected to the transmission belt 323 stops moving, and finally the support plate 2 connected to the traction plate 33 stops moving, that is, the support plate 2 stops at the preset first position; similarly, when the support plate 2 moves from the first position to the second position, the support plate 2 stops at the preset second position.

[0065] In some embodiments of the present application, the sensing member 34 is disposed on the base 1 between the first rotating shaft 321 and the second rotating shaft 322, and a limiting rod is also provided on the base 1 on the side of the second rotating shaft 322 away from the first rotating shaft 321 to limit the traction plate 33 to prevent the traction plate 33 from rushing out of the controllable range of the vehicle operation and maintenance operation device with the support plate 2, thereby improving the safety of the use of the device.

[0066] Optionally, refer to Figure 4A plurality of rollers 10 are provided in the base 1 , and the plurality of rollers 10 are rotatably connected to the base 1 . The plurality of rollers 10 are arranged in sequence and spaced apart along the moving direction of the support plate 2 , and the support plate 2 is slidably connected to the rollers 10 .

[0067] In an embodiment of the present application, the base 1 is provided with a plurality of rollers 10 rotatably connected thereto, and the plurality of rollers 10 are slidably connected to the support plate 2, so that when the support plate 2 switches between the first position and the second position, the friction is smaller and the movement is faster when carrying heavy objects.

[0068] In specific applications, refer to Figure 4 A plurality of rollers 10 are provided on the top of the base 1, and the plurality of rollers 10 are rotatably connected to the base 1. The plurality of rollers 10 are arranged in sequence along the moving direction of the support plate 2, and the support plate 2 is slidably connected to the rollers 10. When the support plate 2 moves between the first position and the second position, the support plate 2 is at least partially slidably connected to the plurality of rollers 10, thereby reducing the friction force of the support plate 2 when it moves and improving the moving speed.

[0069] In some embodiments of the present application, limit plates are further provided on both sides of the drum 10 along a moving direction perpendicular to the support plate, so as to prevent the support plate 2 from deflecting during movement, thereby avoiding the risk of the support plate 2 and the maintenance parts it carries falling.

[0070] It is understandable that the plurality of rollers 10 may also be replaced by slide rails, and the slide rails cooperate with the support plate 2 to reduce friction and increase the moving speed of the support plate 2 .

[0071] Optionally, refer to Figure 1 and Figure 2 The support plate 2 can be moved at least in a horizontal direction to switch between a first position and a second position.

[0072] In the embodiment of the present application, the support plate 2 is connected to the base 1 and can move in a horizontal direction relative to the base 1 under the action of the driving mechanism 3, so that the support plate 2 at least partially extends into the bottom of the vehicle to be repaired, thereby carrying the components of the vehicle to be repaired (not shown in the figure); when the support plate 2 moves in the horizontal direction, the components of the vehicle to be repaired that it carries are placed more stably.

[0073] In a specific application, the support plate 2 moves relative to the base 1 so that the support plate 2 at least partially extends into the bottom of the vehicle to be repaired, and the moving direction can be along the horizontal direction, or the moving direction forms a certain angle with the horizontal direction.

[0074] It can be understood that in order to ensure the stability of the vehicle component to be repaired during movement, it is preferred that the support plate 2 moves in a horizontal direction, so that the vehicle component to be repaired will not deflect or even fall during the movement.

[0075] Optionally, refer to Figure 2 The vehicle operation and maintenance device also includes a moving mechanism 11, which is arranged at the bottom of the base 1 and is used to drive the base 1 to move relative to the vehicle to be repaired.

[0076] In an embodiment of the present application, a moving mechanism 11 is provided at the bottom of the base 1, so that when the vehicle to be repaired needs to be inspected, the moving mechanism 11 drives the base 1 and other components on the base 1 to move to the maintenance position of the vehicle to be repaired for inspection, thereby improving the convenience of the vehicle operation and maintenance device.

[0077] In specific applications, refer to Figure 2 The mobile mechanism 11 includes but is not limited to: a wheeled mobile mechanism, a crawler mobile mechanism, a stepping mobile mechanism, etc. Those skilled in the art can select them according to actual needs, and the embodiments of the present application do not limit this.

[0078] It can be understood that by moving the mobile mechanism 11 on the ground or the workbench, the vehicle operation and maintenance operation device is driven to move as a whole, so that the position of the vehicle operation and maintenance operation device can be more conveniently adjusted to adapt to different vehicle maintenance parts; when the support plate 2 carries maintenance parts, the vehicle operation and maintenance operation device carrying the maintenance parts can be transported to the maintenance workshop through the mobile mechanism 11 to repair the maintenance parts, thereby reducing manpower input and improving transportation efficiency.

[0079] In some embodiments of the present application, reference Figure 1 and Figure 2 Taking rail vehicle maintenance as an example, the vehicle to be repaired (not shown in the figure) is generally located on the vehicle track beam 4. During maintenance, the vehicle operation and maintenance operation device needs to be moved to the side of the vehicle track beam 4 through the mobile mechanism 11. After the parts of the vehicle to be repaired that need to be repaired or replaced are disassembled onto the support plate 2, the vehicle operation and maintenance operation device can be transferred to the maintenance workshop through the mobile mechanism 11 for more detailed inspection or replacement; or, the vehicle operation and maintenance operation device can be transferred from one part to be repaired to the next part to be repaired through the mobile mechanism 11, which improves the convenience of using the vehicle operation and maintenance operation device.

[0080] Optionally, refer to Figure 6 or Figure 7 The vehicle operation and maintenance device also includes: a lifting mechanism 5, which is suitable for being arranged at the bottom of the vehicle. When the support plate 2 is in the second position, the lifting mechanism 5 is located below the support plate 2. The support plate 2 is detachably connected to the base 1. The lifting mechanism 5 can drive the support plate 2 to move up and down to adjust the height of the support plate 2.

[0081] In the embodiment of the present application, the lifting mechanism 5 is provided so that when the vehicle is repaired, the lifting mechanism 5 is placed at the bottom of the vehicle, and then when the support plate 2 is in the second position, it is located above the lifting mechanism 5, and the support plate 2 is detachably connected to the base 1, and the lifting mechanism 5 can drive the support plate 2 to move up and down to adjust the height of the support plate 2. Thus, the lifting mechanism 5 replaces manpower to lift the support plate 2 to the bottom of the maintenance component, and after carrying the maintenance component, the support plate 2 is lifted and lowered, thereby reducing the input of manpower and improving the maintenance efficiency.

[0082] In specific applications, refer to Figure 1 or Figure 6 or Figure 7 A lifting mechanism 5 is provided at the bottom of the vehicle maintenance area. When the support plate 2 is in the second position, the lifting mechanism 5 is lifted and lowered and drives the support plate 2 to move up and down, bringing the support plate 2 to the bottom of the maintenance component for easy loading. After loading the maintenance component, the lifting mechanism 5 is lowered and drives the support plate 2 and the loaded maintenance component to be lowered, so as to facilitate the retraction of the support plate 2 back to the base 1.

[0083] Furthermore, the support plate 2 is detachably connected to the base 1. When the lifting mechanism 5 drives the support plate 2 to rise, the support plate 2 is separated from the base 1 and the traction mechanism 3. When the lifting mechanism 5 descends and the support plate 2 falls back onto the base 1, the card slot 21 is carded on the card connection portion 331 of the traction mechanism 3, so that the traction mechanism 3 drives the support plate 2 to reciprocate between the first position and the second position. The support plate 2 is carded and connected to the card connection portion 331 of the traction mechanism 3 as a whole through the card slot 21, so as to realize horizontal movement.

[0084] It can be understood that the lifting mechanism 5 has a first supporting surface, and the plurality of rollers 10 arranged on the base 1 have a second supporting surface. When the lifting mechanism 5 is in the initial position, the first supporting surface and the second supporting surface are flush, and both the first supporting surface and the second supporting surface are higher than the top surface of the vehicle track beam 4, so that the support plate 2 can move back and forth smoothly between the first position and the second position.

[0085] Optionally, refer to Figure 3 and Figure 5 The traction mechanism 3 includes a traction plate 33 , a clamping groove 21 is provided on one side of the support plate 2 facing the traction plate 33 , a clamping portion 331 is provided in the traction plate 33 , and the clamping groove 21 is clamped to the clamping portion 331 along the vertical direction.

[0086] In the embodiment of the present application, the traction mechanism 3 includes a traction plate 33, a slot 21 is provided on one side of the support plate 2 facing the traction plate 33, a clamping portion 331 is provided in the traction plate 33, and the slot 21 is clamped to the clamping portion 331 in the vertical direction. In this way, when the lifting mechanism 5 rises and drives the support plate 2 to rise, the support plate 2 is separated from the traction plate 33; and when the lifting mechanism 5 descends, the support plate 2 falls back onto the base 1, and the slot 21 is clamped to the clamping portion 331 of the traction plate 33, so that the traction plate 33 drives the support plate 2 to switch between the first position and the second position, and the support plate 2 is clamped to the clamping portion 331 of the traction plate 33 through the slot 21, so as to realize horizontal movement.

[0087] In some embodiments of the present application, the support plate 2 and the traction plate 33 are detachably connected by means of pins and pin holes. Thus, while ensuring the stability of horizontal movement, when the support plate 2 needs to be raised or lowered, the pins and the pin holes are separated, thereby achieving the separation of the support plate 2 and the traction plate 33.

[0088] Optionally, refer to Figure 6 The lifting mechanism 5 includes: a movable base 51, a lifting platform 52 and a second driving member (not shown in the figure). The lifting platform 52 is movably connected to the movable base 51. The second driving member is connected to the lifting platform 52 and is used to drive the lifting platform 52 to move relative to the movable base 51, so that the lifting platform 52 drives the support plate 2 to move up and down.

[0089] In the embodiment of the present application, the lifting platform 52 is movably connected to the mobile base 51, and the second driving member is connected to the lifting platform 52 and drives the lifting platform 52 to move relative to the mobile base 51, so that the lifting platform 52 drives the support plate 2 to move up and down. In this way, the mobile base 51 moves within the vehicle track beam 4 to the vehicle maintenance area, and the lifting platform 52 is driven by power to move relative to the mobile base 51, driving the support plate 2 to move up and down, thereby reducing manpower input, improving maintenance efficiency, and ensuring maintenance safety to a certain extent.

[0090] It can be understood that the movable base 51 is provided with a movable part, and the movable part can be a roller, a track, a slide rail, etc. Technical personnel in this field can select according to actual needs, and the embodiment of the present application does not limit this.

[0091] It can be understood that the lifting platform 52 and the second driving member can transmit the driving force for the lifting movement through a hydraulic structure, a worm gear, a ball screw and other structures. Technical personnel in this field can choose according to actual needs, and the embodiments of the present application do not limit this.

[0092] In specific applications, refer to Figure 6 or Figure 7Driven by the second driving member, the lifting platform 52 rises to the bottom of the support plate 2, driving the support plate 2 to rise to the bottom of the maintenance component. After carrying the maintenance component, the second driving member drives the lifting platform 52 to fall back, and the slot 21 of the support plate 2 is re-engaged with the clamping portion 331 of the traction mechanism 3. Driven by the first driving member 31, the support plate 2 moves from the second position to the first position carrying the maintenance component.

[0093] Optionally, refer to Figure 6 and Figure 7 A limiting groove 521 is provided on the lifting platform 52 , and a supporting beam 22 is provided at the bottom of the supporting plate 2 . When the supporting plate 2 is located at the second position, the supporting beam 22 is at least partially located in the limiting groove 521 .

[0094] In the embodiment of the present application, a support beam 22 is provided at the bottom of the support plate 2. When the support plate 2 moves from the first position to the second position, the support beam 22 is at least partially located in the limiting groove 521. By setting the limiting groove 521, a certain guiding and limiting effect can be played during the movement of the support plate 2.

[0095] It can be understood that when the support plate 2 moves from the first position to the second position, one end of the support beam 22 extends from the base 1 and extends into the limiting groove 521, and the other end slides along the limiting groove 521 to the lifting platform 52, and the inner width of the limiting groove 521 should be greater than the width of the support beam. In this process, the support beam 22 is slidably connected with the roller 10 on the base 1, resulting in relative sliding.

[0096] In some embodiments of the present application, reference Figure 6 A plurality of ball bearings 523 are arranged in the limiting groove 521. When the support beam 22 is located in the limiting groove 521, the plurality of ball bearings 523 are in contact with the support beam 22. Thus, after the support plate 2 carries the maintenance component, it is easier to adjust the position within a small range within the limiting groove 521.

[0097] Optionally, refer to Figure 6 and Figure 7 The lifting mechanism 5 also includes a pin (not shown in the figure), a first hole 221 is provided in the support beam 22, and a second hole 522 is provided in the lifting platform 52. When the support plate 2 is in the second position, the pin is sequentially passed through the first hole 221 and the second hole 522 to limit and fix the support plate 2 and the lifting platform 52.

[0098] In the embodiment of the present application, when the support plate 2 is located in the second position, a pin shaft (not shown in the figure) is sequentially passed through the first hole 221 in the support beam 22 and the second hole 522 in the lifting platform 52, so that when the support plate 2 is in the second position, there is no large-scale offset between the support plate 2 and the lifting platform 52, thereby ensuring the safety of the maintenance parts carried.

[0099] It can be understood that when the support plate 2 is located in the second position, the lifting platform 52 rises and drives the support plate 2 to rise and fall. At this time, the support plate 2 is separated from the base 1 and the traction mechanism 3, and a pin shaft is used to limit and fix the support plate 2 and the lifting platform 52 to maintain the stability of the support plate 2, thereby improving the transportation safety of the maintenance parts.

[0100] In some embodiments of the present application, the diameter of the second hole 522 is greater than the diameter of the first hole 221, so that after the pin shaft passes through the first hole 221 and the second hole 522 in sequence, the support plate 2 can also move in a small range, so that when preparing to carry the maintenance parts, a small range of position adjustment can be performed, so that the maintenance parts can fall on the support plate 2 more stably.

[0101] Optionally, refer to Figure 6 and Figure 7 The lifting mechanism 5 also includes a slide rail 53 , and the movable base 51 is slidably connected to the slide rail 53 . The movable base 51 can move relative to the slide rail 53 to adjust the position of the lifting platform 52 .

[0102] In the embodiment of the present application, the lifting mechanism 5 further includes a slide rail 53, and the mobile base 51 is slidably connected to the slide rail 53. The mobile base 51 can move relative to the slide rail 53 to adjust the position of the lifting platform 52. In this way, after the maintenance of one maintenance area is completed, the lifting mechanism can slide to the next maintenance area through the slide rail 53, avoiding the need for manual lifting mechanism 5 to carry and transfer, thereby improving the efficiency of maintenance.

[0103] It can be understood that in actual application, the extension direction of the slide rail 53 is consistent with the extension direction of the vehicle track beam 4, and the slide rail 53 is laid between two vehicle track beams 4, so as to facilitate the transfer of the lifting mechanism 5 between different maintenance areas.

[0104] In some embodiments of the present application, a storage space may be further provided in the base 1, and maintenance-related tools and the like may be placed in the storage space to improve the utilization rate of the vehicle operation and maintenance device.

[0105] In some embodiments of the present application, reference Figure 8 and Fig. 9 The vehicle operation and maintenance device also includes a bracket 23, which is arranged on the support plate 2 and is detachably connected to the support plate 2.

[0106] It is understandable that in some cases, the lifting distance of the lifting mechanism 5 may not be enough. In this case, the bracket 23 is clamped on the support plate 2, thereby increasing the height of the maintenance parts and making it more convenient.

[0107] Optionally, refer to Figure 1An embodiment of the present application also provides a track maintenance vehicle, including the vehicle operation and maintenance device in any of the above embodiments, and the track maintenance vehicle is used to repair track vehicles.

[0108] In the embodiment of the present application, the rail maintenance vehicle includes a vehicle operation and maintenance device for repairing rail vehicles. Figure 1 The rail vehicle runs on the vehicle track beam 4. When the rail vehicle needs to be repaired, the track maintenance vehicle is moved to one side of the track beam 4, and then the parts of the rail vehicle to be repaired are repaired or replaced through the vehicle operation and maintenance device.

[0109] The vehicle operation and maintenance device includes: a base 1, a support plate 2 and a traction mechanism 3, wherein the support plate 2 is movably connected to the base 1, the traction mechanism 3 is arranged on the base 1 and connected to the support plate 2, and the traction mechanism 3 is used to drive the support plate 2 to move relative to the base 1 so that the support plate 2 switches between a first position and a second position; wherein, when the support plate 2 is in the first position, the support plate 2 is located in the base 1, and when the support plate 2 is in the second position, the support plate 2 is at least partially suitable for extending into the bottom of the rail vehicle to be repaired to carry the maintenance parts of the vehicle. In this way, the maintenance parts are transported and replaced by extending the retractable support plate 2 into the bottom of the rail vehicle, thereby reducing the input of manpower and material resources and improving the maintenance efficiency; at the same time, the safety during maintenance is improved.

[0110] Other components of the vehicle operation and maintenance device according to the embodiment of the present application, such as a control cabinet and a control panel, are known to ordinary technicians in the field and will not be described in detail here.
