Description

Technical Field

[0001] The present invention relates to the technical field of urban public transportation, and in particular to an urban rail transit system. Background Art

[0002] With the development of the automobile industry and the continuous advancement of urbanization, the improvement of people's living standards, the number of cars has also increased significantly, and the problem of urban road congestion has become one of the important issues restricting urban development. At present, the urban traffic solution for most cities is mainly the three-dimensionalization of urban traffic. By changing the original road plane intersection to a three-dimensional intersection, some large cities also use underground transportation and ground transportation to effectively alleviate traffic pressure. However, the construction of such transportation facilities requires a large amount of capital investment and a long construction period. In particular, the implementation of underground projects is also restricted by local geological and geomorphological factors. Bus Rapid Transit (BRT) is currently a popular transportation solution. It is a new type of public passenger transportation system between Rapid Rail Transit (RRT) and Normal Bus Transit (NBT). It is a large-capacity transportation mode that realizes rail transportation operation services and reaches the level of light rail service. A unique urban passenger transportation system, but the actual effect of this solution is not satisfactory. Although some of them facilitate the operation of buses, they affect the smooth flow of other types of vehicles.

[0003] So people thought of using aerial tracks and vehicles running on the aerial tracks to realize urban rail transit operation services. The aerial tracks are tracks at a certain height from the ground, with a station set up at a certain distance; the vehicles run on the aerial tracks and stop to pick up and drop off passengers when they arrive at the station. Since the aerial tracks are at a certain height from the ground, the supporting stations need to reach a corresponding height, which occupies a large area and is expensive. In order to reduce the overall cost of the rail transit system, it is usually adopted to increase the distance between stations. This makes the station layout too sparse, which is inconvenient for citizens to take the train nearby, restricting the development of urban rail transit operation services. For this reason, it is necessary to develop an urban rail transit system that is more convenient for citizens to take the train and has a lower cost. Summary of the invention

[0018] In another preferred embodiment, the car lifting mechanism comprises a plurality of car lifting hydraulic cylinders, the cylinder bodies of the car lifting hydraulic cylinders are fixedly mounted on the vehicle frame, the piston rods of the car lifting hydraulic cylinders are downwardly directed and connected to the car, and the car is raised or lowered by contracting or extending the piston rods of the car lifting hydraulic cylinders.

[0019] In a specific solution, the car lifting mechanism includes four car lifting hydraulic cylinders, which are arranged in two rows and two columns. The four car lifting hydraulic cylinders are arranged in two rows and two columns to balance the force on the car.

[0020] Usually, the above-mentioned traveling mechanism includes a traveling frame, two front wheels and two rear wheels, and the two front wheels and the two rear wheels are all connected to the driving motor. The driving motor drives the two front wheels and the two rear wheels to rotate (the transmission mechanism and driving method thereof can be designed with reference to ordinary automobiles), so that the traveling mechanism, the frame and the car move along the aerial track together. The traveling mechanism cooperates with the aerial track in such a way that the left front wheel and the left rear wheel are on the left wheel support bottom plate, and the right front wheel and the right rear wheel are on the right wheel support bottom plate.

Each guide wheel group includes at least one guide wheel, and each guide wheel is rotatably installed on the steering guide frame. The two guide wheel groups are located on both sides of the middle partition of the aerial track; when the vehicle reaches the turning part of the aerial track, the guide wheel group on one side of the steering guide frame contacts one side of the middle partition, prompting the steering guide frame to rotate inwardly at the turning point, thereby realizing the steering of the front wheels. The above-mentioned drive motor drives the two front wheels and the two rear wheels to rotate, and the two front wheels and the two rear wheels cooperate with the aerial track to make the running mechanism, the frame and the car move along the aerial track together; by setting the front differential and the rear differential, when the vehicle is turning, the left and right front wheels can rotate at different speeds (when turning, the speed of the inner front wheel decreases, and the speed of the outer front wheel increases), and the left and right rear wheels can rotate at different speeds (when turning, the speed of the inner rear wheel decreases, and the speed of the outer rear wheel increases).

[0022] The above-mentioned running mechanism usually also includes a braking device, which is used to stop the front and rear wheels from rotating when parking is required, and to stop the running frame at a predetermined position of the aerial track, thereby stopping the running mechanism, the frame and the car. The braking device can adopt existing conventional equipment, for example: adopt a braking device similar to that of an ordinary car to stop the front and rear wheels from rotating; and set an auxiliary braking device on the running frame, the auxiliary braking device includes a left brake pad, a right brake pad and a brake pad opening and closing mechanism, the left brake pad and the right brake pad are respectively located on both sides of the middle partition, and the brake pad opening and closing mechanism can control the opening and closing of the left brake pad and the right brake pad (when the brake pad opening and closing mechanism drives the left brake pad and the right brake pad to move toward each other, the left brake pad and the right brake pad clamp the middle partition of the aerial track to fix the position of the running frame; when the brake pad opening and closing mechanism drives the left brake pad and the right brake pad to move in reverse, the left brake pad and the right brake pad are separated from the middle partition, and will not hinder the running of the running mechanism along the aerial track).

[0023] The above-mentioned walking bracket is usually provided with a power terminal, which contacts and cooperates with the power supply line arranged at the lower edge of the partition in the middle of the aerial track, and connects electric energy from the power supply line for use by power devices such as the drive motor on the vehicle.

The gap between the two plug-in components in the plug-in mechanism is aligned with the corresponding clamping cross bar. The plug reset spring can apply a thrust to the plug seat and the plug toward the corresponding socket. When the car rises to a high position, the plug-in pieces of each plug-in assembly are inserted into the corresponding sockets, and the plug-in pieces clamp the clamping crossbar (at this time, the clamping crossbar is between the two plug-in assemblies of the plug-in mechanism, and the plug-in piece reset spring is in an extended state. The plug-in piece remains in an inserted state under the action of the plug-in piece reset spring to prevent the plug-in piece from loosening), which can better fix the car on the frame to ensure safety. When the car needs to be lowered, the hydraulic rods of each plug-in mechanism extend, so that the two plug-in assemblies move back to back along the translation guide rail, so that each plug-in piece is disengaged from the socket on the clamping crossbar, so that the car can be lowered relative to the frame.

[0025] In a more preferred solution, the cross-section of the above-mentioned clamping crossbar is a trapezoid (preferably an isosceles trapezoid) with a small top and a large bottom. In the plug-in mechanism, the distance between the inner end faces of the two plug-ins gradually increases from top to bottom. In this way, an inlet with a large width at the bottom and a small width at the top is formed between the inner end faces of the two plug-ins, so that the clamping crossbar can smoothly enter the gap between the two plug-in components (in the process of the clamping crossbar rising, the clamping crossbar gradually pushes the two plug-ins outward, and the plug-in reset spring is compressed at this time; when the plug hole on the clamping crossbar reaches the position corresponding to the plug, the plug reset spring stretches, so that the plug is automatically inserted into the corresponding plug hole).

[0026] In a specific solution, each clamping crossbar is provided with two pairs of plug holes, and there are four pairs of plug holes on the two clamping crossbars, and correspondingly, four plug-in mechanisms are provided on the frame. The four plug-in mechanisms are usually located at the four corners of the same rectangle.

The station is used to receive the lowered car for passengers to get on and off. Normally, the station door panel closes the station door to prevent ground vehicles and personnel from entering; the vehicle stops when it reaches the top of the station, and then the car is lowered, and the lowered car enters the space inside the wall through the car entrance and exit at the top of the wall, and falls on the car support plate, and then the station door and the car door are opened to get on and off; after the passengers are boarded and off, the car door and the station door are closed, the car rises, and the vehicle runs to the next station. The above-mentioned compression springs play a buffering role, reducing the impact force of the descending car on the car support plate and the base; the above-mentioned compression springs also play a role in stabilizing the car. After the car falls on the car support plate, the car exerts pressure on the car support plate by relying on its own weight, and each compression spring is compressed to exert an upward force on the car support plate, providing a certain bearing capacity for the car, so that the car is close to the car support plate, effectively preventing the car from swaying, and helping the car to maintain a stable position.

The lifting guide devices can guide the car support plate to rise and fall more smoothly, and further prevent the car support plate and the car from swaying.

[0031] In a more preferred embodiment, a plurality of anti-slip strips are provided on the upper surface of the above-mentioned car support plate, each anti-slip strip has the same direction, and there is a strip groove between two adjacent anti-slip strips. By providing the anti-slip strips, the friction between the car and the car support plate can be increased, and the dislocation of the car parked on the car support plate can be effectively avoided.

The forward or reverse rotation of the power output shaft of the station door panel unit translation motor can drive the lower roller to rotate forward or reverse, thereby driving the corresponding station door panel unit to translate, thereby realizing the opening or closing of the station door (the station door is opened when the two station door panel units move in opposite directions, and the station door is closed when the two station door panel units move toward each other).

[0033] Usually, the aerial track is shared by vehicles on multiple different routes. The aerial track is in a grid-like shape with multiple X-shaped intersections or Y-shaped intersections. Track conversion or switching devices need to be set up at these intersections so that vehicles can continue to run along the predetermined route when they reach the intersection.

At the X-shaped intersection of the aerial track, the aerial track has four track ends (track end refers to the end of a section of track), two of which are aligned with each other, and the other two are aligned with each other; the four first track hanging parts on the first track bearing platform are respectively hung on these four track ends (after installation, the first track hanging parts can be welded to the corresponding track ends), so as to fix the track cross conversion device on the aerial track; the four transition track segments are respectively connected to the four track ends. At the X-shaped intersection, when the vehicle needs to pass from one track end to another track end aligned with it, the rotating disk driving device drives the rotating disk to rotate in advance, so that the transfer rail rotates to the position corresponding to the two track ends.

When the rotating disk driving motor drives the driving gear to rotate, the driving gear drives the rotating disk to rotate through the driven gear, thereby switching the position of the transfer rail.

[0036] In a more preferred embodiment, a limiting cylinder is provided in the central portion of the first track support platform, and a through hole is provided at the portion of the limiting cylinder corresponding to each transition track segment; a limiting ring is provided at the bottom of the rotating disk, and the limiting ring is located in the opening at the top of the limiting cylinder. The outer wall of the limiting ring cooperates with the top of the inner wall of the limiting cylinder to limit the rotating disk. Each through hole connects the internal cavity of the corresponding transition track segment with the cavity of the limiting cylinder. When two transition track segments are connected by a transfer rail, the corresponding two through holes connect the internal cavity of the transfer rail with the internal cavity of the two transition track segments to form a passage for vehicles to pass through.

[0102] The translation mechanism includes a translation motor 66, a driving gear 67 and a transverse rack 68. The translation motor 66 is fixedly mounted on the second track bearing platform 62. The second track bearing platform 62 is provided with a transverse guide rail 622.

The strip groove 623 is provided with a plurality of evenly arranged balls 624. The lower surface of the translation seat unit 631 contacts the balls 624 on the two support rails 6221. When the translation motor 66 drives the driving gear 67 to rotate, the driving gear 67 drives the transmission shaft 69 to rotate, and drives the transverse racks 68 to move synchronously through the transmission gears 610, thereby driving the translation seat units 631 to move to the desired position along the transverse guide rail 622, and switching the positions of the first transfer rail 64 and the second transfer rail 65. Each translation seat unit 631 is connected to different positions of the first transfer rail 64 and the second transfer rail 65, which can improve the bearing capacity of the first transfer rail 64 and the second transfer rail 65.

[0103] The second rail hanging part 621 includes a second hanging plate 6211, and second side limit plates 6212 and 6213 are respectively provided on both sides of the second hanging plate 6211. The upper edges of the two second side limit plates 6212 and 6213 are respectively connected to the edges of both sides of the second hanging plate 6211. The cross-section of the second rail hanging part 621 is a U-shape with an opening downward.

[0104] The second support frame 61 is fixedly installed on the ground and is used to support the track fork switching device 6 .

[0105] At the Y-shaped intersection of the aerial track 1 (i.e., the junction or fork of the track), the aerial track 1 has three track ends 4, one of which is on one side of the track fork switching device, and the other two are on the other side of the track fork switching device; the three second track hanging parts 621 on the second track bearing platform 62 are hung on these three track ends 4 respectively (when the second track hanging part 621 is combined with the track end 4, the second hanging plate 6211 is superimposed on the top surface of the track end 4, and the two second side limit plates 6212 and 6213 are respectively on both sides of the track end 4 and close to the side of the track end 4; after installation, the second track hanging part 621 can be welded to the corresponding track end 4), so as to fix the track fork switching device on the aerial track 1. The cross-sectional shape and size of the first transfer rail 64 and the second transfer rail 65 are consistent with the track end 4.

[0106] In the urban rail transit system of the present invention, the traveling mechanism 22 directly cooperates with the aerial track 1, and relies on the driving motor 24 to drive the traveling mechanism 22 to operate, so that the entire vehicle moves on the aerial track 1; the car 23 for passengers to ride can be raised and lowered, and a station 3 for accommodating the car 23 is set to facilitate passengers getting on and off the car.

[0107] 1. The working principle of vehicle 2 is:

[0108] When the vehicle moves on the aerial track 1, the car 23 rises to a high position, and the top of the car 23 is connected to the bottom of the frame 21 by a buckle mechanism, so that the car 23 is firmly fixed to the frame 21. When the vehicle arrives at the station, it stops, the buckle mechanism is released, and the car lifting mechanism drives the car 23 to descend relative to the frame 21. The lowered car 23 stops at the station, and the car door 234 is opened for passengers to get on and off; after the passengers are boarded and off, the car door 234 is closed, and the car lifting mechanism drives the car 23 to rise relative to the frame 21, and the top of the car 23 is reconnected to the bottom of the frame 21 by the buckle mechanism, and the vehicle moves to the next station.

[0109] The drive motor 24 provides power for the traveling mechanism 22 and the car lifting mechanism, and uses the first clutch and the second clutch to control the separation or engagement of the power transmission. When the car 23 needs to be raised or lowered, the first clutch is engaged (the second clutch is disengaged at this time), and the drive motor 24 can drive the winding wheels 25 to rotate synchronously, reeling in or unreeling the ropes 26, so that the length of the drooping part of each rope 26 is shortened or extended, thereby raising or lowering the car 23. When the traveling mechanism 22 needs to be operated, the second clutch is engaged (the first clutch is disengaged at this time), and the drive motor 24 drives the traveling mechanism 22 to operate, so that the entire vehicle moves on the aerial track 1.

[0110] When the driving motor 24 drives the two front wheels 229 and the two rear wheels 2210 to rotate, the two front wheels 229 and the two rear wheels 2210 cooperate with the aerial track 1 to move the walking mechanism 22, the frame 21 and the car 23 along the aerial track 1; by setting the front differential 227 and the rear differential 228, when the vehicle is turning, the left and right front wheels 229 can rotate at different speeds (when turning, the speed of the inner front wheel decreases, and the speed of the outer front wheel increases), and the left and right rear wheels 2210 can rotate at different speeds (when turning, the speed of the inner rear wheel decreases, and the speed of the outer rear wheel increases).

[0111] When the vehicle 2 reaches the turning part of the aerial track 1, the guide wheel group 2212 on one side of the steering guide frame 222 contacts one side of the middle partition 16, prompting the steering guide frame 222 to rotate inwardly of the turning, thereby realizing the steering of the front wheel 229 and allowing the vehicle to pass the turning part smoothly.

[0112] 2. The working principle of station 3 is:

[0113] The station 3 is used to receive the lowered car 23 for passengers to get on and off. Usually, the station door 332 is closed by the station door panel 333 to prevent ground vehicles and personnel from entering; Figure 8 The vehicle runs on the aerial track 1 and stops when it reaches the top of the station 3. Then the car 23 is lowered. The lowered car 23 enters the space inside the wall 33 through the car entrance 331 at the top of the wall and falls on the car support plate 32. Then the station door 332 and the car door 234 are opened to allow passengers to get on and off. After the passengers are boarded and off, the car door 234 and the station door 332 are closed, the car 23 rises, and the vehicle runs to the next station.

[0114] Each compression spring 34 plays a buffering role, reducing the impact force of the descending car 23 on the car support plate 32 and the base 31; in addition, after the car 23 falls on the car support plate 32, the car 23 exerts pressure on the car support plate 32 by its own weight, and each compression spring 34 is compressed to exert an upward force on the car support plate 32, providing a certain bearing capacity for the car 23, so that the car 23 is close to the car support plate 32, effectively preventing the car 3 from swaying, which is conducive to keeping the car 3 in a stable position. Each lifting guide device 35 can guide the car support plate 32 to rise and fall more smoothly.

[0115] The forward or reverse rotation of the power output shaft of the station door panel unit translation motor can drive the lower roller to rotate forward or reverse, thereby driving the corresponding station door panel unit 3331 to translate, thereby realizing the opening or closing of the station door 332 (the station door 332 opens when the two station door panel units 3331 move back to back, and closes when the two station door panel units 3331 move toward each other).

[0116] 3. The working principle of the track cross conversion device 5 is:

[0117] At the X-shaped intersection, when the vehicle needs to pass from one track end 4 to another track end 4 aligned with it, the rotating disk drive device drives the rotating disk 53 to rotate in advance, so that the transfer rail 54 rotates to the position corresponding to the two track ends 4. At this time, the two transition track segments are connected through the transfer rail 54 and the corresponding two transition track segments 55. The center line of the transfer rail 54 is in a straight line with the center line of the two transition track segments 55, so that the two track ends 4, the two transition track segments 55 and the transfer rail 54 are connected in a straight line, so that the vehicle can pass through the X-shaped intersection smoothly.

[0118] 4. The working principle of the track bifurcation switching device 6 is:

[0119] When the vehicle needs to pass over a certain track end 4 on the other side from the track end 4 on one side, the translation mechanism drives the translation seat 63 and the first transfer rail 64 and the second transfer rail 65 to translate horizontally in advance, so that the first transfer rail 64 or the second transfer rail 65 moves to the position corresponding to the two track ends 64. At this time, the two track ends 64 are connected through the first transfer rail 64 or the second transfer rail 65, so that the two track ends 4 and the first transfer rail 64 (or the second transfer rail 65) are connected in a line, so that the vehicle can pass through the Y-shaped intersection smoothly. The trajectory of the first transfer rail 64 and the second transfer rail 65 is determined according to the direction of the three sections of the track at the Y-shaped intersection. When the two track ends 4 are connected through the first transfer rail 64 (or the second transfer rail 65), the first transfer rail 64 (or the second transfer rail 65) and the corresponding two sections of the track form a smoothly connected track.

[0120] In other embodiments, the above-mentioned car lifting mechanism may also include a winding motor, a plurality of winding wheels and a plurality of ropes; the winding motor is fixedly mounted on the frame; each winding wheel can be rotatably mounted on the frame, and each winding wheel is drivingly connected to the power output shaft of the winding motor; the number of ropes and winding wheels is the same and corresponds one to one, one end of the rope is connected to the corresponding winding wheel, and the other end is connected to the car. The winding motor can drive each winding wheel to rotate synchronously, reel in or unreel each rope, shorten or lengthen the length of the drooping part of each rope, and thus raise or lower the car. The difference between this scheme and the above-mentioned preferred embodiment is that winding and traveling are each driven by a motor, and other structures can be the same.

[0121] In other embodiments, the above-mentioned car lifting mechanism may also include a plurality of car lifting hydraulic cylinders (e.g., four, arranged in two rows and two columns), the cylinder body of each car lifting hydraulic cylinder is fixedly mounted on the frame, and the piston rod of each car lifting hydraulic cylinder is downwardly connected to the car. The car is raised or lowered by contracting or extending the piston rod of each car lifting hydraulic cylinder.
