Description

Technical Field

[0001] The invention relates to a public transportation system, in particular to a running drive device of a public transportation vehicle. Background Art

[0002] Land public transportation systems mainly include bus passenger transport, subways, urban light rail, trains, high-speed trains, etc. The vehicles or trains in these transportation systems must operate according to the dispatching. However, along the way in the operation area, there are many complex factors such as traffic posts, forks, traffic jams, stops at stations, speed limits, parking and waiting, restarting driving, and the stationmasters between stations are not fixed, which inevitably lead to the disorder of the time interval and even the order of the operation. It is not easy to keep the overall transportation system in good operation order. Even if there is a rigorous system operation and dispatching system and equipped with corresponding professional and technical personnel, once there is a dislocation of the operation order, it will affect the overall public transportation system and even cause the system to collapse. Therefore, the current public transportation system has the technical problems of low operation efficiency, many and uncontrollable factors affecting the operation order, high coordination difficulty, and high professional requirements. There are also technical problems such as large cumulative energy consumption of transportation tools, high component loss, complicated maintenance types, and high costs.

[0003] Patent document CN110422180A discloses a non-stop public transportation system and a method for not affecting passengers getting on and off during non-stop operation. The power locomotive tows a non-powered trailer and basically maintains a non-stop speed on a closed-loop track. When passing each station along the way, a section of arc-shaped undulating auxiliary track is used to implement the replacement of the front and rear trailers to ensure that passengers get on and off the locomotive while the locomotive is running. The key technical link in the realization of this technical solution is how to ensure that the power locomotives on the circular track can always maintain a safe operating distance and eliminate rear-end collisions that lead to system collapse accidents. If this technical problem is not solved, the realization of this new type of efficient public transportation system will face great technical obstacles. However, the existing manual scheduling, intelligent scheduling, and manual and intelligent combined scheduling methods are difficult to achieve 100% safe cyclic operation performance, and the technical difficulty faced in technical improvements is high, lacking cost-effectiveness in practical applications. Summary of the invention

[0004] The invention purpose of this patent application is mainly aimed at the non-stop public transportation system, starting from the system structure itself, cleverly resolving the technical obstacles of station location setting, eliminating the safety driving loopholes between vehicles of each shift in the operating range, and providing a new type of non-stop public transportation operation power system.

[0005] The technical solution of the non-stop public transportation operation power system provided by this patent application mainly includes: a non-stop public transportation operation power system, the components of which include a chain part, a chain guide part and a chain drive part;

[0006] The chain part is a chain device connected end to end and parallel to the public transportation running track. The power car unit of the public transportation is installed on the chain device at intervals. The chain device is composed of a plurality of chain links and chain link plates hinged between the chain links, wherein the chain link plates have meshing teeth on their sides;

[0007] The chain driving part includes a power source and a driving gear of the power source output shaft, and the driving gear is in driving engagement with the meshing teeth of the chain link plate;

[0008] The chain guide part is a guide wheel group which forms a chain guide channel on both sides of the chain device.

[0009] One of the preferred options of the above overall technical solution is that the chain link plate is a groove-shaped component, and its groove-shaped bottom surface is formed with meshing teeth on the chain link plate that mesh with the driving gear, and its groove-shaped space is used to accommodate the chain links connected.

[0010] One of the preferred options of the above overall technical solution is that on the chain portion, a link axis separated by a number of chain links is a long axis protruding from the plane on the link, and the bottom of the power vehicle unit is mounted on the upper end of the long axis of the chain link.

[0011] One of the preferred options of the above-mentioned overall technical solution is that the guide wheel group has a guide roller on one side and a guide gear meshing with the meshing teeth of the chain link plate on the other side, and the guide roller and the guide gear form a running route that limits the chain device.

[0012] One of the preferred options of the above overall technical solution is that the guide roller is an "I"-shaped guide wheel with upper and lower protruding edges.

[0019] The non-stop public transportation operation power system disclosed in the present invention is the main technical means to support the non-stop operation of the public transportation system. The power car units 3 of each shift in the operation section are driven by the operation power system and run repeatedly along the operation track 1. At each station 5, with the assistance of the auxiliary track 6, the front and rear unloading and load transfer of the loaded non-powered trailer 9 and the non-powered trailer 9a to be loaded are completed. Figure 1 and Figure 2 shown.

[0020] In this public transportation system, the power vehicle unit 3 is driven by the operating power system, so it does not need to be equipped with its own driving power. It can be equipped with a backup power drive device unless it needs to be inspected or other reasons to leave the operating track 1 in the operating section and needs to move on its own.

[0021] The running power system is composed of three parts: a chain part, a chain guide part and a chain drive part.

[0022] The chain part is a chain device 4 which is parallel to and end-to-end connected with the public transportation circular running track 1, on which a power vehicle unit 3 is connected at a spacing set according to the shift requirements. The power vehicle unit 3 is driven by the chain driving part 2 and guided by the chain guiding part. Driven by the chain device 4, the power vehicle unit 3 runs along the running track 1.

[0023] In the chain device 4, between each group of two adjacent chain links 11 and 12, a chain link plate 10 is hingedly connected to its adjacent chain link shaft 16, and is continuously connected according to the mileage of the operating range. The chain link plate 10 is provided with meshing teeth 17 on one side.

[0024] The chain guide is a guide wheel set arranged on both sides of the chain device 1, which is used to limit the running track of the chain device 1. The chain guide has a variety of implementation structures, which can be guide rollers arranged on both sides of the chain device 1, with the wheel axle seat installed on the bottom plate 24 along the line, or Figure 3 As shown, one side is a guide roller 22, and the other side is a guide gear 23 meshing and guiding with the meshing teeth 17 of the chain link plate 10. The guide roller 22 and the guide gear 23 form a running route for limiting the chain device 1.

[0025] like Figure 4 As shown, the bottom plate 24 along the line is transversely fixed on the rail sleeper 15 of the running track 1; the guide roller 22 is preferably an "I"-shaped guide wheel with upper and lower protruding edges, and the axial length between the upper and lower protruding edges is basically the height of the chain device 1.

[0026] The chain drive unit 2 is as follows: Figure 4 As shown, it includes a motor 20 as a power source, and a driving gear 21 on the output shaft of the motor reduction box. The driving gear 21 is well meshed with the meshing teeth 17 of the chain link plate 10, and the chain device 1 runs under the drive of the motor 20.

[0027] In the operation area of ​​the public transportation system, a group of chain driving parts 2 with the same rotation speed is added in each mileage section or on the slope section to ensure the stable driving operation performance of the chain device 1.

[0028] In this embodiment, in order to improve the stability and reliability of the chain drive unit 2 in the chain device 4, in this embodiment, the chain link plate 10 is a groove-shaped component, and the bottom surface of the groove is provided with meshing teeth 17 on the chain link plate 10 that mesh with the driving gear 21. The left and right chain links 11 and 12 are placed in the groove space and are hingedly connected to the adjacent chain link shafts 16 of the two chain links 11 and 12. Because the meshing teeth 17 have a larger meshing surface with the driving gear 21, the stability of the transmission coordination is improved and the meshing noise is reduced.

[0029] On the chain segment of the chain device 4 where the power car unit 3 is located, it is best to have a chain link axis with equal chain link number intervals as a long body axis 13 protruding from the upper plane of the chain body, and a hanger 14 is fixed at the same interval at the bottom of the power car unit 3, and the upper end of the chain link long body axis 13 is inserted into the axial hole of the hanger 14, so that the chain device 1 of the power car unit 3 is hung, and the power car unit 3 moves forward along the running track 1 driven by the chain device 1.
