Description

Technical Field

[0001] The invention belongs to the technical field of air-rail transportation, and mainly relates to an air-rail top-mounted vehicle stabilizer. Background Art

[0002] Skytrain, also known as "suspended rail train," is a type of monorail system. Its tracks are suspended above the train, supported in the air by steel or concrete columns. It's suitable for intercity rail travel.

[0003] The aerial rail has the advantages of low construction cost, fast construction, small footprint, detachable and movable, full process automation, environmental protection, low noise and energy saving.

[0004] The stability of vehicle operation is a crucial factor in the operation of SkyRail trains. Because the trains are suspended upside down from the track beams, they experience a wobble when passengers board and alight, without any other means of stabilizing them. This creates a sense of insecurity and discomfort for passengers. This wobble also creates a large gap between the train and the platform, significantly impacting passenger safety. Therefore, the development of a stabilizing device to ensure the safety and stability of trains entering and exiting stations is a critical technical challenge facing SkyRail technology.

[0005] When a suspended rail train is going through a curve or subjected to lateral forces, the car can swing to eliminate the impact and vibration, which can improve passenger comfort. However, when the vehicle stops at a station, passengers need to get on and off, so the vehicle needs to be stable and not shake. In order to solve this problem of not shaking when stopping at a station, a stabilizer is generally installed at the platform. The stabilizer drives a long-arm connecting rod through a power device such as a switch or an electric motor to rotate the stabilizer axle. When the stabilizer axle rotates, it will also rotate the stabilizer wheel synchronously. Finally, the stabilizer wheel is stuck in the stabilizer groove side plate at the bottom of the car to achieve stability. Each car is equipped with two stabilizers.

[0006] At present, the stabilizing devices of suspended trains are all set on the platform base and connected to the bottom of the suspended train for stabilization. For example, "A stabilizing device for a suspended train" with application number CN202222475928.8 and "A stabilizing device for a suspended monorail train" with application number CN202320813548.2 both stabilize the train at the bottom of the train.

[0007] The existing vehicle stabilizer has the following disadvantages:

[0008] 1. Ordinary vehicle stabilizers are expensive because of their complex structure and the use of self-locking motors or switch machines in the driving part.

[0009] 2. The vehicle stabilizer is very large, occupying a significant amount of space beside the platform tracks and impacting construction in the platform area. In particular, the vehicle stabilizer bar is located high above the platform, requiring installation and commissioning at height, posing a risk of falling. Furthermore, the entire device is heavy, making commissioning and measurement difficult.

[0010] 3. The driving part of the car stabilizer is installed in the platform area, which requires the design of a large foundation pit. After installation, a separate inspection port needs to be designed. Since the inspection port needs to be used for passengers to walk, there are also requirements for strength and insulation. Summary of the Invention

[0011] To address these issues, the present invention proposes a device for stabilizing the top of an aerial rail vehicle, known as an "aerial rail roof-mounted stabilizer." This device is compact and simple, requiring no platform space, is lightweight, and inexpensive. Furthermore, it features a simple structure and is easy to maintain. The technical solution employed is as follows.

[0012] An aerial rail top-mounted car stabilizer, comprising: a control system, a braking system, a hydraulic system and a car stabilizing mechanism; characterized in that: the car stabilizing mechanism is arranged on the top of the train; the car stabilizing mechanism comprises a "downward pressure" mechanism and a "upward pressure" mechanism; the "downward pressure" mechanism comprises a tilting and stabilizing seat, a cover, an electric push rod, a drive shaft, a support seat, a rotating shaft, a stop pin, a downward pressure limit stroke switch and a retraction limit stroke switch; the "downward pressure" mechanism is mounted on the track beam through fasteners; the "upward pressure" mechanism comprises a hydraulic lifting rod, a push rod, a jack base, an oil supply pipe, a buffer rubber Rubber pad, micro switch; the "upward push" mechanism is installed on the roof empty spring plate through fasteners; the support seat on the "downward pressure" mechanism is movably connected with the drive shaft and the rotating shaft, and the horizontal "downward pressure" working state and the vertical retracted non-working state are realized by the extension and contraction of the electric push rod; the push rod on the "upward push" mechanism completes the "upward push contact" and "downward movement separation" with the horizontal bottom surface of the support seat on the "downward pressure" mechanism through the linkage instructions of the control system, braking system and hydraulic system; the "upward push" force and stroke of the push rod on the "upward push" mechanism are controlled by the micro switch.

[0013] Furthermore, the telescopic stroke of the electric push rod on the "pressing down" mechanism is controlled by triggering the pressing limit stroke switch and the retracting limit stroke switch with the stop pin on the support seat.

[0014] Furthermore, the stop pin is fixedly connected to the support seat and slides in the limit groove as the support seat flips, thereby triggering the downward limit travel switch and the retraction limit travel switch.

[0015] Furthermore, the buffer rubber pad is located between the support seat and the push rod.

[0016] Furthermore, the contact plane between the support seat and the push rod is a knurled friction plane.

[0017] Furthermore, the ejector rod is moved electrically, pneumatically or hydraulically.

[0018] Furthermore, the vehicle stabilizing mechanisms are symmetrically distributed between the vehicle roof and the track beam, with the number being 4 or more groups.

[0019] The "top-mounted" stabilizer mechanism of the air-railway top-mounted stabilizer of the present invention has significant advantages over the current "bottom-mounted" stabilizer, and its beneficial effects are as follows:

[0020] 1. The overall vehicle stabilization mechanism is small in size and occupies less space in the platform area;

[0021] 2. The overall stabilizing mechanism has a compact structure and low cost;

[0022] 3. The overall vehicle stabilization mechanism has a simple structure and is easy to maintain;

[0023] 4. The overall train stabilization mechanism cleverly uses the principle of mechanical leverage to allow a smaller cylinder to generate greater force, saving costs and making the train's parking more stable.

[0024] 5. The top-mounted stabilizer's stabilizing actuator operates stably, has a fast stabilizing speed, and has a strong stabilizing force; the release time is short, and the train's stopping and starting efficiency is high, effectively improving passenger experience and train operation safety.

Specific implementation methods

[0033] In order to more clearly express the technical solution of the present invention, a detailed description is given below with reference to the accompanying drawings.

[0034] See attached Figures 1-6 , an air-rail overhead stabilizer includes: a control system, a braking system, a hydraulic system and a stabilizer mechanism; it is characterized in that: the stabilizer mechanism is arranged on the top of the train; the stabilizer mechanism includes two parts: a "downward pressure" mechanism and a "upward pressure" mechanism; the "downward pressure" mechanism includes a downward-turning stabilizer seat 1, a cover 101, an electric push rod 102, a drive shaft 103, a support seat 104, a rotating shaft 105, a stop pin 106, a downward pressure limit stroke switch 107, and a retraction limit stroke switch 108; the "downward pressure" mechanism is installed on the track beam 3 by fasteners; the "upward pressure" mechanism includes a hydraulic jacking rod 2, a jack 201, a jack base 202, an oil supply pipe 20 3, buffer rubber pad 204, micro switch 205; the "upward push" mechanism is installed on the roof empty spring plate 4 by fasteners; the support seat 104 on the "downward pressure" mechanism is movably connected with the drive shaft 103 and the rotating shaft 105, and the horizontal "downward pressure" working state and the vertical retracted non-working state are realized by the extension and contraction of the electric push rod 102; the push rod 201 on the "upward push" mechanism completes the "upward push contact" and "downward movement separation" with the horizontal bottom surface of the support seat 104 on the "downward pressure" mechanism through the linkage instructions of the control system, braking system and hydraulic system; the "upward push" force and stroke of the push rod 201 on the "upward push" mechanism are controlled by the micro switch 205.

[0035] The telescopic stroke of the electric push rod 102 on the "pressing down" mechanism is controlled by triggering the pressing limit stroke switch 107 and the retracting limit stroke switch 108 through the stop pin 106 on the support seat 104.

[0036] The stop pin 106 is fixedly connected to the support base 104 and slides in the limit groove 109 as the support base 104 turns over, thereby triggering the downward limit travel switch 107 and the retraction limit travel switch 108.

[0037] The buffer rubber pad 204 is located between the support seat 104 and the push rod 201 to buffer the "collision" between the support seat 104 and the push rod 201, and plays a role in buffering the collision force generated by the "downward pressure" and "upward pressure" of the stabilizer, and controls the pressure value generated between the "downward pressure" and "upward pressure" of the stabilizer through its buffering time, thereby effectively protecting the support seat 104 and the push rod 201 and their vehicle body.

[0038] The contact surface between the support seat 104 and the push rod 201 is a knurled friction surface, so as to increase the friction force of the contact between them and achieve the effect of stabilizing the vehicle.

[0039] The ejector rod 201 is moved electrically, pneumatically or hydraulically.

[0040] The vehicle stabilizing mechanisms are symmetrically distributed between the vehicle roof and the track beam, and the number of the mechanisms is 4 or more.

[0041] Specifically, when the vehicle stops for passenger pickup or drop-off, the control system and braking system initiate commands to activate the hydraulic system, driving the vehicle stabilization mechanism. This activates the tilting stabilizer seat 1, pushing the electric push rod 102 downward. This push rod 102, via the drive shaft 103, rotates the support base 104 about the rotation axis 105. When the support base 104 rotates until its bottom surface is horizontal, the stop pin 106 triggers the downward travel limit switch 107, causing the motor of the push rod 102 to stop pushing downward and generate a reverse current. This reverse current only maintains the push rod 102 stationary and maintains a certain force. Simultaneously, the push rod 201 on the spring plate 4, under commands from the control system and braking system, begins to rise until the rubber cushion 204 contacts the bottom surface of the support base 104. At this point, the microswitch 205 triggers, causing the push rod 201 to stop rising and maintain a certain holding force. The force applied is sufficient to stabilize the vehicle body without damaging the spring plate 4 or the tilted support base 104. At this point, the vehicle stabilizer is in operation.

[0042] When the vehicle is ready to move after stabilizing, the lower push rod 201 begins to descend under the control system's command. After the push rod 201 is fully retracted, the "upward push" mechanism executes the command and returns to its initial state. At this point, the control system issues a command for the electric push rod 102 to begin retracting, and the support base 104 of the "downward pressure" mechanism begins to tilt and rotate upward until the stop pin 106 moves and triggers the retraction limit switch 108. At this point, the electric push rod 102 stops retracting and receives a reverse current. At this point, the entire movement stops, the "downward pressure" mechanism executes the command and returns to its initial state, and the vehicle can leave the platform.

[0043] The invention discloses an aerial railway top-mounted vehicle stabilizer which firmly stabilizes a suspended train on a track beam through four top-mounted vehicle stabilizers, so that the vehicle will not shake when passengers get on and off the train.

[0044] To achieve synchronization, the oil supply to all hydraulic jacks and the power supply to the entire stabilizer system are coordinated by a controller installed on the vehicle. The coordination instructions for the stabilizers are issued by the control center, ensuring that all systems operate in an orderly manner when the vehicle stops.
