[0053] Example 1

[0054] See also Figures 1 to 6 The main body of the present embodiment 1 is a rail system for maintenance equipment of an embedded maglev rail vehicle, the rail system comprises a power supply rail 1 and a reaction rail 2 symmetrically arranged on the left and right sides of the rail vehicle, the power supply rail 1 and the reaction rail 2 cooperate with each other to form a track for the passage of the maglev rail vehicle, the power supply rail 1 is divided into at least two sections 11 spaced apart from each other along its extension direction;

[0055] The track system also includes a lifting unit 3, which is embedded between two adjacent sections 11 of the power supply rail 1, and is constructed to be able to move up and down between a first position and a second position. When the lifting unit is located at the first position, its top surface is flush with the top surface of the power supply rail 1 and constitutes a part of the track. When the lifting unit is located at the second position, it extends upward from the power supply rail 1 to lift the maglev rail vehicle that falls on the power supply rail 1.

[0056] In specific implementation, the maglev rail vehicle enters the track formed by the lifting system through a trolley or its own original track. When the maglev rail vehicle moves to a suitable position, the power supply rail 1 is powered off, so that the maglev rail vehicle falls on the power supply rail 1; then, the lifting unit 3 can move vertically to lift the entire maglev rail vehicle, making it convenient for the implementation personnel to carry out maintenance work.

[0057] The jacking system in this embodiment couples the track and the jacking unit 3 that specifically performs the jacking action, so that the maglev rail vehicle can be jacked directly by moving it onto the track. Compared with the traditional method, which does not require an additional temporary arrangement of the jacking unit 3, the operation efficiency is higher.

[0058] In addition, it is worth noting that in this embodiment, the jacking unit 3 is flush with the power rail 1 under normal conditions, and is not immersed in the section 11 of the power rail 1. The advantage of this arrangement is that when the power rail 1 is powered off and the entire maglev rail vehicle falls on the power rail 1, the jacking unit 3 and the power rail 1 can provide more stable support for the maglev rail vehicle together, avoiding the occurrence of overhanging parts of the maglev rail vehicle.

[0059] In addition, for the embedded maglev rail vehicle, since its running part is embedded, if the lifting unit 3 directly lifts it, it is restricted by the reaction rail 2 and the lifting height of the entire rail vehicle is limited; so in this embodiment, see Figure 2 The reaction rail 2 can move relative to the power supply rail 1 to switch between the first position and the 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 rail vehicle to pass; when the reaction rail 2 is in the second position, it can avoid the upper space between the power supply rail 1 on the same side and the power supply rails 1 on both sides, so that the maglev rail vehicle can be freely lifted to a suitable height.

[0060] In this embodiment, the reaction rails 2 on both sides are installed on the telescopic rods of the cylinders 4, and the reaction rails 2 on both sides can move along the left and right sides under the drive of the corresponding cylinders 4. At the same time, the cylinders 4 are correspondingly placed in the frame body 5 for installation and fixation; the top of the frame body 5 is covered with a movable dust cover plate 6. A stopper 7 is also provided between the power supply rails 1 on both sides.

[0061] As a preferred embodiment, in this embodiment, the number of sections 11 into which each side power rail 1 is divided is more than three. The purpose of setting such a structure is to increase the number of jacking units 3 in each side power rail 1, so as to provide more supporting points for the maglev rail vehicle and reduce the risk of overturning when the maglev rail vehicle is jacked up.

[0062] In this embodiment, the lifting unit 3 is specifically lifted by a driving device. Of course, the implementer can also set a hand-driven device to replace the driving device.

[0063] In conventional methods, the number of actuators used to simultaneously lift the maglev rail vehicle is often large (for example, as disclosed in Chinese invention document No. CN111348576A), and each component is affected by the control accuracy, and non-coordinated actions are inevitable.

[0064] Therefore, in this embodiment, the system further includes:

[0065] A connector 8, the connector 8 is installed on the left and right sides, and each lifting unit 3 embedded in the power supply rail 1 is fixedly connected to the connector 8 on the same side;

[0066] The driving device acts on the connecting body 8 to drive the lifting unit 3 to move vertically relative to the power supply rail 1 .

[0067] That is to say, the driving device drives the lifting unit 3 on one side to lift by acting on the connecting body 8. This arrangement can reduce the number of actuators in the driving device, thereby reducing the risk of non-coordinated actions.

[0068] In this embodiment, the number of components of the driving device is two groups, and the two groups of driving devices act on the connecting bodies 8 on the left and right sides respectively.

[0069] See also Figure 5 More specifically, in this embodiment, the driving device has a plurality of driving units 9, each of which has a fixed end and a movable end capable of vertically moving relative to the fixed end, and each movable end of the driving unit 9 is fixedly connected to a corresponding connecting body 8;

[0070] The connector 8 is in a rectangular parallelepiped shape, and the length direction of the connector 8 is consistent with the extension direction of the power supply rail 1;

[0071] The positions where the connector 8 is connected to the movable ends of the driving units 9 are arranged in sequence along the length direction of the connector 8 .

[0072] The above structure can effectively ensure that the lifting force of the driving unit 9 applied to the connecting body 8 can be evenly transmitted to the lifting unit 3, and improve the stability of the system during lifting.

[0073] More specifically, in this embodiment, the connector 8 is a hollow rectangular steel support beam, and the drive unit 9 is a hydraulic cylinder. Hollow rectangular steel has the advantages of high standardization and easy availability.

[0074] In addition, more importantly, different from the prior art that uses a movable fork frame to lift the embedded maglev rail vehicle (such as the Chinese invention document with publication number CN111348576A), in this embodiment, the top surface of the lifting unit 3 is used to contact the bottom of the running part of the maglev rail vehicle to lift the maglev rail vehicle. The structure of this device is simpler and avoids the need for an additional movable mechanism on the lifting unit 3.

[0075] The power rail 1 will form a track for the maglev rail vehicle to pass only when it is powered on. In this embodiment, the power rail 1 is divided into a plurality of sections 11 spaced apart from each other, and the implementer can independently power each section 11 to ensure the normal operation of the power rail 1.

[0076] However, it is obvious that this method has a high implementation cost, so in this embodiment, the multiple sections 11 in each power rail 1 are electrically connected to each other to minimize the deployment cost. Specifically, a conductor 12 is provided between two adjacent sections 11 in each power rail 1, and the two adjacent sections 11 are electrically connected to each other through the conductor 12 therebetween. The conductor 12 is bent to avoid space for placing the lifting unit 3.

[0077] See also Figure 6 In this embodiment, the lifting unit 3 includes:

[0078] A first insulating portion, wherein a top surface of the first insulating portion defines a top surface of the lifting unit 3;

[0079] The skeleton 33 is used for being fixedly connected to the connector 8 , and the first insulating part is fixed on the top of the skeleton 33 .

[0080] This arrangement can prevent the current carried by the maglev rail vehicle from being transmitted to the connector 8 and the drive unit 9 .

[0081] In order to improve the contact stability and reduce the deflection of the running gear of the maglev rail vehicle during lifting, in this embodiment, the top of the first insulating part is in a concave shape in the middle to form multi-surface contact.

[0082] In detail, the first insulating part is specifically composed of a first nylon plate 31 and two second nylon plates 32 arranged on both sides of the first nylon plate 31. The top surface height of the first nylon plate 31 is lower than the top surface height of the second nylon plate 32, so that the top surface of the lifting unit 3 is limited only by the second nylon plate 32.

[0083] As a preferred embodiment, in this embodiment, the lifting unit 3 further includes:

[0084] At least two second insulating parts 34 are fixedly covered on two opposite sides of the frame 33 along the extension direction of the power rail 1. The second insulating parts 34 avoid the possibility of the lifting unit 3 being electrified from the side, thereby improving the safety of maintenance personnel. The second insulating parts 34 are also made of nylon.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
