Description

Technical Field

[0001] The present application relates to the field of rail transportation, and in particular to a maintenance station for a monorail system and a monorail system. Background Art

[0002] In the existing field of rail transportation, the monorail system is particularly involved. The existing monorail systems include straddle-type monorails and suspended monorails. When building maintenance stations for EMUs, these types of monorail systems usually require independent maintenance lines of the maintenance stations, which can be connected to the transportation lines through turnouts. Whether it is a straddle-type monorail or a suspended monorail with various structural forms, the maintenance time of EMUs is usually long. Therefore, the maintenance line is not suitable for being directly connected in series with the transportation line. At the same time, it also leads to a more complex construction structure and a much higher cost when the maintenance station is built.

[0003] In addition, in order to reduce costs, the maintenance stations in the prior art usually set up several large maintenance stations to carry out centralized maintenance of the EMUs, which greatly increases the comprehensive distance from the EMUs to the maintenance stations and reduces the efficiency of EMU maintenance. Summary of the invention

[0004] Based on the existing design, the present application provides a maintenance station and a monorail system for a monorail system.

[0005] A maintenance station for a monorail system comprises a maintenance section rail beam that occupies a portion of a transport line, a transfer device disposed above or / and below the maintenance section rail beam, and a mobile support body that supports the movement of the maintenance section rail beam;

[0006] The inspection section track beam is composed of two main bodies which are symmetrically arranged with respect to the running direction, and at least one main body moves laterally along the moving support body.

[0007] Optionally, the two main bodies of the inspection section track beam move laterally along the movable support body.

[0008] Optionally, the two main bodies of the inspection section track beam move in opposite directions along the movable support body.

[0009] Optionally, the transfer device arranged above the track beam of the maintenance section is a lifting sling.

[0010] Optionally, the transfer device arranged below the track beam of the maintenance section is a lifting and carrying device.

[0011] Optionally, the length of the track beam in the maintenance section is at least greater than the length of a motor vehicle running along the track beam.

[0012] Optionally, the transfer device at least includes a motor vehicle transfer device.

[0013] Optionally, the EMU transfer device is at least provided with a vertical transfer function for the EMU.

[0014] Optionally, the monorail system includes any one of a suspended monorail system and an embedded monorail system.

[0015] The present application also provides a technical solution of the second aspect, namely a monorail system, comprising any of the aforementioned maintenance stations for the monorail system, wherein the maintenance section track beam is a partial section of the transportation line.

[0016] The present application is used in the maintenance station of the monorail system, and its working process is as follows: when the EMU passes through the maintenance section track beam, if the EMU needs maintenance, one or both of the main bodies of the maintenance section track beam are moved to enable the EMU to leave the position of the maintenance section track beam through the transfer device to the maintenance area set elsewhere. If the maintenance time of the EMU is in progress, one or both of the main bodies can be restored to be connected with the transportation line after the EMU leaves the maintenance section track beam, so that the function of the maintenance section track beam passing can be realized.

[0017] The maintenance station for the monorail system of the present application can be directly set up on the transportation line. Through the above-mentioned setting, the normal passage of the motor vehicle will be affected only when the motor vehicle is transferred. In other cases, the normal passage of the motor vehicle will not be affected. This impact can be completely eliminated when the overall scheduling of the transportation line is reasonable. The maintenance station has a simple structure and does not need to independently set up the maintenance line and track beam through the turnout, thereby reducing the construction cost of the maintenance station. In addition, by setting up multiple maintenance stations described in this application in the transportation line of the monorail system, the comprehensive distance from the motor vehicle that needs maintenance to the maintenance station can be shortened, thereby improving the comprehensive maintenance efficiency of the motor vehicle.

[0028] The present solution is described below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Please refer to Figure 1 and Figure 2 , Figure 1 , Figure 2 The schematic diagrams are respectively the structural diagrams of the vertical running direction and the parallel running direction of the maintenance station for the monorail system. The maintenance station is arranged in the track line, the track line can be a suspended monorail or an embedded monorail, and the corresponding track beam is a suspended track beam or an embedded track beam.

[0030] The maintenance station includes a mobile support body 1, a maintenance section track beam 3, a transfer device and a motor vehicle maintenance system. The two ends of the maintenance section track beam 3 directly match the connecting line track beam 2, and the length of the maintenance section track beam 3 satisfies that it is at least greater than the length of a motor vehicle 4 running along the track beam. During normal passage, the motor vehicle 4 can directly pass through the maintenance station through the maintenance section track beam 3; the maintenance section track beam 3 is supported by the mobile support body 1, and can move laterally in the lateral movement channel of the mobile support body 1. The transfer device includes a lifting sling 5 and a lifting load-bearing device 6. The lifting sling 5 is arranged above the maintenance section track beam 3, and the lifting load-bearing device 6 is arranged below the track beam. Sliders 7 are provided on both sides along the running direction. The sliders 7 on both sides can slide in the direction perpendicular to the running direction. The sliders 7 are provided with a running surface matching the motor vehicle 4. The central axis of the lifting load-bearing device 6 along the running direction is in the same vertical plane as the central axis of the maintenance section track beam 3 and the lifting sling 5 along the running direction.

[0031] The maintenance section track beam 3 is composed of multiple main bodies, preferably two main bodies are set, namely the first main body 3a and the second main body 3b. Among them, the first main body 3a and the second main body 3b are symmetrical about the vertical central axis plane of the maintenance section track beam 3 composed of them along the running direction. During normal passage, the maintenance section track beam 3 composed of the first main body 3a and the second main body 3b is matched and connected with the line track beam 2 front and back, and the motor vehicle 4 can directly pass through the maintenance station through the maintenance section track beam 3. The maintenance section track beam 3 formed by the first main body 3a and the second main body 3b should have an upper opening and a lower opening. The first main body 3a and the second main body 3b can move in the movable support body 1 and the transverse moving channel, and preferably the moving directions of the two are opposite.

[0032] Please refer to Figure 3 to Figure 6 , Figure 3 to Figure 6 The figure is a schematic diagram of the steps of moving the motor vehicle 4 from the maintenance section track beam 3 to the state to be maintained. The motor vehicle 4 to be maintained is parked at the lower part of the maintenance section track beam 3, and the lifting device 5 grabs and fixes the motor vehicle 4 parked on the maintenance section track beam 3 through the upper opening of the maintenance section track beam 3, and then the first body 3a and the second body 3b of the maintenance section track beam 3 move apart on both sides, so that the lower opening width of the maintenance section track beam 3 is larger than the width of the motor vehicle 4. The lifting sling 5 lowers the EMU 4 to the lifting load-bearing device 6. When lowering, the sliding member 7 of the lifting load-bearing device 6 is first separated to both sides. When the connection part of the EMU 4 grabbing the container or the carriage is lower than the height of the sliding member 7 and the running wheels of the power bogie are higher than the height of the sliding member 7, the sliding member moves toward the middle to make the running wheels of the power bogie match the running surface on the sliding member 7. The grabbing part of the lifting sling 5 rises back to the initial position. Then, the first main body 3a and the second main body 3b of the maintenance section track beam 3 move toward the inside to match the line track beams 2 at both ends. At this time, the EMU 4 can directly pass through the maintenance section track beam 3 to pass through the maintenance station.

[0033] After the EMU 4 is transferred from the maintenance section track beam 3 of the maintenance station set up in the operating line to the lifting load-bearing device 6, the EMU maintenance system can be used to maintain the EMU 4, and the EMU 4 can run on the running surface of the lifting load-bearing device 6 to move to different maintenance areas.

[0034] In addition, when the maintenance is completed, the first main body 3a and the second main body 3b of the maintenance section track beam 3 are separated to both sides, the grabbing part of the lifting sling 5 descends to grab and fix the EMU 4, and then the sliding part 7 of the lifting bearing device 6 is separated to both sides, and the lifting sling 5 lifts the EMU 4, and rises to the height of the power bogie of the EMU 4 to be consistent with the running space, the first main body 3a and the second main body 3b of the maintenance section track beam 3 move inward to make the running wheels of the power bogie of the EMU 4 match the running surfaces of the first main body 3a and the second main body 3b, and finally the grabbing part of the lifting sling 5 releases the EMU 4 and rises back to the initial position.

[0035] After completing the above steps, the EMU 4 can continue to move along the track beam. At the maintenance station, at least a vertical transfer function is set for the maintenance EMU 4, so that the maintenance EMU 4 can be transferred between the maintenance section track beam 4 and the lifting load-bearing device 6. In addition, it can also be transferred horizontally within the lifting load-bearing device 6 to reach different maintenance locations.

[0036] Please refer to Figure 7 , Figure 7 It is a schematic diagram of a normally-traveled EMU 4 passing through a maintenance station via the maintenance section track beam. When in the traffic state, other normally-traveled EMUs 4 can directly pass through the maintenance station via the maintenance section track beam 3. Only when the EMU 4 to be repaired is transferred downward or completed at the maintenance station, other EMUs 4 on the same track line cannot pass normally. Therefore, the impact on the EMUs 4 on the same track line is relatively small. If the trains are properly dispatched, this impact can even be completely eliminated.

[0037] Please refer to Figure 8 , Figure 8 This is a top view of the maintenance station for the monorail system. The maintenance station for the monorail system transportation line described in the present application can also include a transfer device for the containers or carriages loaded on the motor vehicle 4. In this embodiment, a transfer trolley 8 is used as the transfer device.

[0038] Please refer to Figure 1 and Figure 8 When the motor vehicle 4 to be overhauled is loaded with containers or carriages, it cannot be directly lowered from the overhaul section track beam 3 to the lifting and carrying device 6. First, the container or carriage must be unloaded, and then the motor vehicle 4 is vertically transferred. The transfer trolley 8 is preferably set as a height-liftable trolley. When the motor vehicle 4 loaded with containers or carriages is about to enter the station, it should first stop at the end of the line track beam 2 connected to the overhaul section track beam 3. Then the transfer trolley 8 runs to the bottom of the motor vehicle 4, so that the vertical projection of the container or carriage is located in the loading part of the transfer trolley 8. The loading part of the transfer trolley 8 is raised so that its loading part contacts the bottom of the container or carriage. At this time, the grabbing part of the motor vehicle 4 is released, so that the container or carriage is loaded onto the transfer trolley 8. The loading part of the transfer trolley 8 is lowered, so that the center of gravity is lowered and the stability is improved. Finally, the transfer trolley 8 stops and waits in the parking area of ​​the overhaul station.

[0039] After the maintenance of EMU 4 is completed, EMU 4 stops below the head end of the line track beam 2 connected to the running direction of the maintenance section track beam 3, and the transfer trolley 8 travels to the bottom of EMU 4, so that the container or carriage falls into the vertical projection of the loading part of EMU 4, the loading part of the transfer trolley 8 rises, and the loading part of EMU 4 grabs and fixes the container or carriage, and finally the loading part of the transfer trolley 8 descends, and the transfer trolley 8 stops at the parking area, and EMU 4 continues to travel along the line track beam 2.

[0040] Through the above arrangement, the maintenance of the EMU 4 loaded with containers or carriages can be completed, and the transfer device for the containers or carriages loaded on the EMU 4 at the maintenance station of the monorail system is not limited to the above-mentioned transfer trolley 8, but can also be other similar devices that can independently complete the loading, unloading and transportation of containers or carriages loaded on the EMU 4.

[0041] The maintenance station for the monorail system described in the present application has a simple structure and is directly set on the track line. There is no need to separately set up the track line and corresponding switches connecting the maintenance station. Therefore, multiple maintenance stations can be set up in a suspended monorail or embedded monorail line. When the EMU 4 needs to be repaired, the nearest maintenance station can be selected for repair, without running to a distant centralized maintenance station for maintenance, thereby greatly improving the maintenance efficiency of the EMU 4.

[0042] The monorail system described in the present application includes the maintenance station for the monorail system transportation line described in the above application, and the maintenance station is directly set in each line. The maintenance section track beam 3 is matched and connected with the line track beam 2. The EMU 4 that needs maintenance can directly travel to the nearest maintenance station of the line for maintenance, without having to travel a long distance to a separately set up maintenance station, thereby greatly improving the efficiency of maintenance of the EMU 4.

[0043] When the maintenance station on the line has not transferred the EMU 4 to be repaired downward or transferred the EMU 4 that has been repaired upward, the EMU 4 that normally passes on the same line can directly pass through the maintenance station. Therefore, the maintenance station has little impact on the EMU 4 on the line. If properly dispatched, this impact can even be completely eliminated.

In particular, for the system and terminal embodiments, since the methods therein are basically similar to the method embodiments, the description is relatively simple, and the relevant parts can be referred to the description in the method embodiments.
