Description

Technical Field

[0001] The invention belongs to the technical field of rail transportation, and in particular relates to a track changing device for suspended air-rail switching, an air-rail turnout and an air-rail system. Background Art

[0002] The aerial rail train is a city rapid transit bus and a suspended rail transportation system, including track piers, track beams, aerial rail trains and vehicle bogies. The vehicle bogies are arranged on the upper part of the vehicle to drive the aerial rail train to move longitudinally along the track beams. The aerial rail train, that is, the suspended aerial rail, is different from the subway and tram. The track of the suspended aerial rail is above and can be built in near-ground space such as under bridges. It has low construction cost and short construction period. It can effectively alleviate traffic pressure in congested areas.

[0003] With the rapid development of air rail, the development of rail lines presents a trend of network distribution, and the application demand of turnouts has also increased significantly. Turnout systems are set at the intersections of various lines for track change of trains. In the prior art, rotatable turnout arms are set at the intersecting track lines, and the on-off conditions of the corresponding tracks are adjusted by controlling the rotation of the turnout arms. In order to improve the stability of the vehicle body passing through the turnout system, the turnout arm needs to be set to match the corresponding track shape, which leads to a large turnout arm length. When the end of the turnout arm away from its rotation center contacts the corresponding track, its contact surface is small, and the vehicle body will shake during movement due to reasons or parameters such as power transmission and the roughness of the track plane. When the vehicle body passes through the fork connection, the roller of the vehicle body will produce a great impact force on the turnout arm, and this impact force is mainly borne by the contact part between the turnout arm and the corresponding track, which causes the contact part between the turnout arm and the corresponding track to be subjected to a great impact force, and cracks or even fractures will occur at the turnout arm part, which increases the number of later inspections and repairs, and is not conducive to the smooth passage of the vehicle body through the turnout system. Summary of the invention

[0036] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0037] The present invention provides a track-changing device for suspended air-rail switching, that is, for switching tracks at a fork of a bifurcated track beam, the track-changing device comprises a first connecting member, a second connecting member, and a driving device; the two ends of the first connecting member can be connected to the bifurcated portion inside the first track beam to realize the passage of the first track beam, and the two ends of the second connecting member can be connected to the bifurcated portion inside the second track beam to realize the passage of the second track beam, and the first track beam and the second track beam constitute a bifurcated track beam structure, that is, the track-changing device is used to be set at the fork of at least two track beams, and is used to realize switching of different track lines; the driving device drives one of the first connecting member and the second connecting member to move downward to connect with the corresponding track beam, and drives the other to rise to a set height, so as to construct a unique passage at the bifurcated track beam structure; the first track beam and the second track beam can be either straight track beams or curved track beams.

[0038] The following is an intuitive example to further illustrate the track changing device in the present invention. It is assumed that the first track beam is a straight track beam and the second track beam is a curved track beam. The straight track beam and the curved track beam constitute a bifurcated track beam structure. Taking a single-track single opening as an example, when the train goes straight at the bifurcated track entrance without changing tracks, that is, the straight track beam needs to maintain its own connectivity at the bifurcated track entrance, the driving device drives one of the first connecting member and the second connecting member to move downward and dock with the straight track beam to achieve the self-connection of the straight track beam at the bifurcated track entrance, and the train keeps going straight at the bifurcated track entrance. At the same time, the driving device drives the other of the two to rise to a set height without affecting the normal passage of the train. When the train needs to change tracks at the bifurcated track entrance, that is, it needs to be implemented at the bifurcated track entrance When the track needs to be changed, that is, when it is necessary to change the track from the straight track beam to the curved track beam, the driving device drives one of the first connecting member and the second connecting member to move downward and connect with the curved track beam, so as to realize the connection between the curved track beam and the straight track beam at the fork, and realize the track change of the train at the fork. At the same time, the driving device drives the other of the two to rise to a set height without affecting the normal passage of the train; that is, the first connecting member and the second connecting member are moved by the lifting device, and at the same time, only one of them is connected and connected with the corresponding track beam, and the other rises to a set height that does not interfere with the operation of the train. In the present invention, the set height refers to a height higher than the train bogie set according to the height of the train bogie, which does not interfere with the running train.

[0039] It should be noted that, in the present invention, the driving device can directly drive the first connecting member and the second connecting member, or can drive the movement of the first connecting member and the second connecting member through a lifting member, as long as the first connecting member and the second connecting member can be moved and transformed to achieve the purpose of docking with the corresponding track beam.

When the integral forming setting is used, stress and strain sensors can be set at the lower part of the first track part and the second track part to detect their respective deformations, and then ensure safety through alarms.

[0044] Further, see Attachment Figure 3 , Figure 3 yes Figure 1The first embodiment of the track change device shown is a schematic diagram of a three-dimensional structure applied at a track switch.

[0051] See attached Fig. 9 and attached Fig.10 , Fig. 9 1 is a schematic structural diagram of a fourth embodiment of a track changing device for suspended air-rail switching in the present invention. Fig.10 yes Fig. 9Schematic diagram of a three-dimensional structure used in an externally suspended track beam, wherein the first track beam 4 and the second track beam 5 form an externally suspended single-track left-opening turnout track beam structure, at which time the second track beam 5 is in a passage state; the second connecting member 2 is driven by the driving device to move downward to dock with the second track beam 5, thereby realizing the passage of the second track beam, and further, the second track portion 21 of the second connecting member is docked with the walking plate gap between the second track beam and the first track beam, and the second connecting portion 22 of the second connecting member is docked with the web gap between the second track beam and the first track beam, thereby completing the second track beam and realizing the row The vehicle changes track direction from the first track beam to the second track beam; in addition, in the externally suspended track beam, the externally suspended track beam is an I-shaped structure, and the first connecting member and the second connecting member also include a first top plate connection and a second top plate connection portion, which are respectively used to connect with the top plates of the first track beam and the second track beam, and the first top plate connection and the second top plate connection portion arranged at the upper part can bear part of the load of the track plate; at the same time, the first connecting member 1 rises to a set height under the drive of the driving device. In the present invention, the set height refers to a height that does not interfere with the operation of the train, that is, the rising height is greater than the height of the bogie in the train.

[0052] Furthermore, the length of the second connecting portion is greater than the length of the second track portion, that is, when the second connecting member is docked with the second track beam, the second track portion is docked with the walking plate of the second track beam, and the second connecting portion is docked with the web of the second track beam. Due to the structural design, when the train passes through the docking area on the second track beam, the second track portion bears the gravity of the train, and the second track portion disperses part of the load to the second track beam through the second connecting portion connected thereto.

[0053] It should be noted that, in the external suspension embodiment, the track-changing device is used for line switching of the external suspension track. Regardless of whether it is a single-line left-opening turnout or a single-line right-opening turnout structure, the track portion and the connecting portion of the track-changing device are arranged according to the external suspension track beam; usually, at the fork, the main line is a straight track beam, that is, the first track beam is a straight track beam. When the straight track beam needs to be connected, the driving device drives the first lifting component to drive the first connecting component to move downward to dock with the first track beam, and at the same time drives the second lifting component to drive the second connecting component to move upward to a set height to construct a unique passage at the turnout structure; the first track portion, the first connecting portion, and the second track portion The structural shape of the second connecting part is adapted to the shape of the corresponding track beam at the notch; in addition, in the default state, the first track beam is in a connected state, that is, the first connecting component is at the lower limit position, this action is the second action set, when the track needs to be changed at the track fork, the first action set is implemented, that is, the second connecting component is at the lower limit position, connecting the second track beam to achieve track switching, the second action set and the first action set are opposite actions, when the train passes, it is restored to the default state before the implementation of the first action set; the first connecting component and the second connecting component can quickly realize the vehicle track change and vehicle operation, improve the overall operation efficiency, and save track change time.

[0054] Furthermore, in the track change device, the first connecting portion of the first connecting member that is docked with the web can bear the static load and the moving load of the first connecting member; when the first track beam is in a self-connected state, that is, when the first connecting member is lowered to the lower limit position and docked with the notch on the first track beam, when the bogie of the train passes through the first track portion of the first connecting member, the first track portion transmits pressure to the first connecting portion through a vertical limiting member (not shown) between the first connecting portion and the first connecting portion. Because the width of the first connecting portion is greater than the width of the first track portion, the pressure on the first connecting portion can be transmitted to the first track beam through the connecting member and its own structure; at the same time, the side of the first connecting portion facing the train bogie can bear the pressure from the train bogie The invention can transfer the load pressure borne by the first track-changing device in the working state to the first track beam body through the vertical limiting members and the horizontal limiting members, thereby further improving the structural safety performance of the first track-changing device; similarly, the second connecting member in the track-changing device is also provided with vertical and horizontal limiting members having the same function as the first connecting member, that is, when the track parts in different connecting members are in a state of overlapping and docking with the track surface, each track part and each connecting part transfers the load force from the train bogie to the track beam body through the limiting members, thereby dispersing the load-bearing load of the track-changing device, thereby achieving more reliable structural safety of the track-changing device.
