Description

Technical Field

[0001] The present invention relates to the technical field of rail vehicle maintenance, and in particular to an embedded magnetic levitation rail vehicle maintenance device and a method for using the same. Background Art

[0002] Embedded maglev rail vehicles are a type of rail vehicle that has special requirements for maintenance.

[0003] Specifically, when performing maintenance on a rail vehicle, the entire vehicle must be lifted from the maintenance equipment to create a gap between the vehicle and the ground for maintenance personnel to enter. Conventional rail vehicles only require an additional track section at the maintenance equipment, connecting to the normal track, to allow the vehicle to travel over the maintenance equipment and be lifted.

[0004] However, for embedded maglev vehicles, due to their C-shaped track cross-section, if the maintenance equipment were to be connected to the normal track, as previously practiced, the reaction rail on the maintenance equipment would interfere with the vehicle's running gear as the vehicle was lifted, preventing the lifting operation from proceeding normally. Therefore, preventing the maintenance equipment from interfering with the lifting operation of the embedded maglev vehicle became a pressing technical challenge. Summary of the Invention

[0005] The present invention aims to provide an embedded magnetic levitation rail vehicle maintenance device and a method of using the same, which can avoid interference with the jacking action of the embedded rail vehicle.

[0006] The embodiment of the present invention is achieved as follows:

[0007] A maintenance device for an embedded maglev rail vehicle, comprising:

[0008] Two power supply rails are arranged in parallel on both sides of the rail vehicle in the transverse direction of the rail vehicle;

[0009] Two reaction rails located above the power supply rail, the reaction rails being arranged in parallel on both sides of the rail vehicle in the transverse direction of the rail vehicle;

[0010] The reaction rail is configured to be able to move relative to the power supply rail in the transverse direction of the rail vehicle, thereby switching between a first position and a second position; when the reaction rail is in the first position, it is located above the corresponding power supply rail on the same side, so as to cooperate with the power supply rail to form a track for the passage of the maglev rail vehicle; when the reaction rail is in the second position, it is away from each other and away from the power supply rail on the same side, so as to avoid the space above the power supply rail.

[0011] Preferably, the device further comprises a jacking system, and the jacking system is used to jack up the magnetic levitation rail vehicle that falls on the power supply rail.

[0012] Preferably, the device further comprises a driving system for driving the reaction rail to move so as to switch the reaction rail between the first position and the second position.

[0015] Preferably, the drive system includes a plurality of drive units, each of which includes a fixed portion and a movable portion movable relative to the fixed portion. The plurality of drive units are arranged in sequence along the length direction of the reaction track, and the movable portion of each drive unit is connected to the reaction track.

[0016] Preferably, the driving system further comprises a receiving unit, which is in the shape of a frame having an internal space, and each driving unit is received in the internal space of the receiving unit.

[0017] Preferably, the exterior of the receiving unit is at least partially covered with a dust cover plate, and the dust cover plate is movably connected to the receiving unit so as to selectively expose the interior space of the receiving unit or cover the receiving unit.

[0018] Preferably, the accommodating unit includes a plurality of frame bodies arranged in sequence along the extension direction of the reaction rail and having an internal space, the number of the frame bodies corresponds to the number of the driving units, the driving units are accommodated in the internal space of the corresponding frame bodies, at least one beam of the frame body is configured to slide in the internal space of the frame body, the fixed part of the driving unit is fixed to the frame body, and the movable part is fixedly connected to the beam, and the reaction rail is mounted on the beam.

[0019] Preferably, the driving unit is a cylinder.

[0020] Preferably, the track formed by the reaction rail and the power supply rail when the reaction rail is in the first position is used to connect with the embedded magnetic levitation track.

[0021] The present application also provides a method for using the maintenance device as described above, which is characterized by comprising the steps of:

[0022] placing the reaction rail in a first position and moving the magnetic levitation rail vehicle between the reaction rail and the power supply rail of the maintenance equipment;

[0023] Cutting off the power supply rail so that the magnetic levitation rail vehicle lands on the power supply rail of the maintenance equipment;

[0024] The reaction rails are moved laterally away from each other to a second position, thereby clearing the space above the power supply rails, and then the magnetic levitation rail vehicle falling on the power supply rails is lifted.

[0038] Example 1

[0039] See also Figure 1 and Figure 2 This embodiment 1 proposes an embedded maglev rail vehicle maintenance device, the device comprising:

[0040] Power supply rail 1, two power supply rails 1 are installed in parallel on the left and right sides;

[0041] Reaction rails 2, two reaction rails 2 are installed in parallel on the left and right sides;

[0042] Among them, the reaction rail 2 can move relative to the power supply rail 1 to switch between a first position and a second position; when the reaction rail 2 is in the first position, it is above the power supply rail 1 on the same side to cooperate with the power supply rail 1 to form a track for the maglev track vehicle to pass; when the reaction rail 2 is in the second position, it avoids the space above the power supply rail 1 on the same side and the power supply rails 1 on both sides.

[0043] In this embodiment, a power supply rail 1 and a reaction rail 2 are mainly built on the maintenance equipment to enable the embedded maglev rail vehicle to enter and adjust its position on the maintenance equipment. At the same time, the reaction rail 2 can move relative to the power supply rail 1 to avoid the space above the power supply rail 1 and the power supply rails 1 on both sides, so that the embedded maglev rail vehicle can be normally lifted for maintenance operations.

[0044] Specifically, after the embedded maglev vehicle, using its own rails or a transport trolley, moves onto the track formed by the reaction rail 2 and the power rail 1 in the first position, it uses its running gear to move along the track to the desired location. Then, the power rail 1 is de-energized, allowing the entire vehicle body to rest on top of it and be supported by it. At this point, personnel can use a jacking device, independent of maintenance equipment, to lift the entire vehicle body to a desired height without interference.

[0045] Regarding the lifting action of the above-mentioned embedded maglev rail vehicle, in this embodiment, the equipment further includes a lifting system 3, which is used to lift the maglev rail vehicle that has landed on the power supply rail 1. The lifting system 3 is specifically a hydraulic cylinder. It is worth noting that when the reaction rail 2 is in the first position, the hydraulic cylinder should be configured to be locked to avoid accidental interference accidents. At the same time, to prevent maintenance personnel from accidentally coming into contact with the power supply rail 1 after the rail vehicle is lifted, in this embodiment, power supply rail stops 7 are also provided on the inner side of the power supply rails 1 on both sides, and the area between the power supply rail stops 7 on both sides forms an inspection channel.

[0046] The switching of the states of the reaction rail 2 is preferably automatic. Therefore, as a preferred embodiment, in this embodiment, a driving system is further included for driving the reaction rail 2 to move so as to switch it between the first position and the second position. The driving system is used to drive the reaction rails 2 on both sides to move in the same direction or in different directions.

[0047] In this embodiment, the drive system is used to drive the reaction rails 2 on both sides to move away from each other in the left-right direction, thereby avoiding the power rail 1 and the space above the power rails 1 on both sides. The implementer can select the movement direction of the reaction rails 2 according to their own needs. For example, in another embodiment, the reaction rails 2 move in the front-to-back direction to avoid the power rail 1 and the space above the power rails 1 on both sides.

[0048] The movement direction of the reaction rail 2 is not necessarily a straight line, but can also be a curved line, that is, the reaction rails 2 on both sides are flipped around a straight line along the front-to-back direction by the rotating device, which can also achieve the technical effect of avoiding the power supply rail 1 and the upper space between the power supply rails 1 on both sides.

[0049] In this embodiment, for ease of control, the drive system comprises two groups of components, each of which drives the reaction rails 2 on both sides to move. The two drive systems are preferably configured to operate synchronously.

[0050] More specifically, in this embodiment, the drive system includes a plurality of drive units 4, each of which includes a fixed portion and a movable portion that can move relative to the fixed portion. The plurality of drive units 4 are arranged in sequence along the length direction of the reaction rail 2, and the movable portion of each drive unit 4 is connected to the reaction rail 2.

[0051] In this embodiment, the driving unit 4 is a cylinder, but it can also be a linear motor or other device.

[0052] For maintenance equipment, ensuring its own maintenance efficiency and reducing its own maintenance standby time are key factors in determining whether it can be applied to large-capacity lines. In this embodiment, the most prone to failure is the drive units 4, which are numerous and have high coordination requirements.

[0053] Therefore, as a preferred embodiment, the drive system further includes a housing unit, which is frame-shaped and has an interior space. Each drive unit 4 is housed within the interior space of the housing unit. The exterior of the housing unit is also at least partially covered with a dust cover plate 6, which is movably connected to the housing unit, allowing it to selectively expose or cover the interior space of the housing unit. The power rail 1, reaction rail 2, housing unit, and lifting system 3 are all mounted on a base.

[0054] This structural style makes it easy for maintenance personnel to perform maintenance on the entire maintenance device. Specifically, the drive unit 4 in the receiving unit can be replaced or repaired by simply opening the dust cover plate 6. When the entire maintenance device does not need to be maintained, the dust cover plate 6 forms the top surface of the entire receiving unit for personnel to step on.

[0055] In addition, in the present embodiment, the receiving unit includes a plurality of frame bodies 5 arranged in sequence along the extension direction of the reaction rail 2 and having an internal space. The number of the frame bodies 5 corresponds to the number of the drive units 4. The drive units 4 are accommodated in the internal space of the corresponding frame bodies 5. At least one beam 8 of the frame body 5 is configured to slide within the internal space of the frame body 5. The fixed portion of the drive unit 4 is fixed to the frame body 5, and the movable portion is fixedly connected to the beam 8. The reaction rail 2 is mounted on the beam 8. The frame body 5 is made of rectangular steel sheets. In the present embodiment, the frame bodies 5 are spaced apart, but the frame bodies 5 can also be made to be connected as one.

[0056] Those skilled in the art will understand that the frame body 5 mentioned above means that it is composed of multiple beams.

[0057] As previously described, the embedded maglev track vehicle can be moved onto the track formed by the reaction rail 2 and the power supply rail 1 in the first position using its own track or a transport trolley. In this preferred embodiment, the track formed by the reaction rail 2 and the power supply rail 1 in the first position is used to connect with the embedded maglev track, eliminating the need for an inconvenient trolley and improving maintenance efficiency.

[0058] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
