Description

Technical Field

[0001] The invention belongs to the technical field of train fault braking, and in particular relates to a mechanical support type parking device and method for a high-speed maglev train with a ramp fault. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] High-speed maglev trains can generally reach 400 km / h to 600 km / h. They have the advantages of fast, low consumption, environmental protection, and safety. They have broad application prospects and are particularly suitable for medium and long-distance operations. Since the maglev system must be supplemented by electromagnetic force to complete suspension, guidance, and driving, the safety of the train in the event of a power outage is an issue that must be considered. Trains need to be suspended at a specific height to run normally, and the protection measures for dangers are not as many as those for high-speed railways and EMUs. Therefore, protection against sudden failures of high-speed maglev trains is very important. Ramp failure is a power failure scenario for high-speed maglev trains. When a power failure occurs on a ramp, the train will slide down. Although the sliding speed will not be too high, it will still cause damage to passengers and the train. Summary of the invention

[0004] In order to solve the above problems, the present invention proposes a mechanically supported parking device and method for a high-speed maglev train ramp failure, which can perform emergency treatment to avoid casualties or train damage caused by the train sliding from the top of the slope to the bottom of the slope when the slope failure is caused by the failure of the train traction system. It can effectively reduce the hazards of ramp failure and greatly improve the safety and reliability of the operation of high-speed maglev trains.

[0011] As a further technical definition, the support plate includes a support sleeve and a support panel that are fixedly connected; the support sleeve is sleeved on the outside of the support spring.

[0012] Furthermore, the size of the supporting panel matches the size of the supporting groove.

[0013] Furthermore, the depth of the support groove is greater than the height of the support panel perpendicular to the direction of the support sleeve.

[0014] As a further technical limitation, the mechanical shaft is controlled by a motor or mechanically to achieve rotation at a limited angle.

[0032] Embodiment 1

[0033] Embodiment 1 of the present invention introduces a mechanical support parking device for a high-speed maglev train in case of ramp failure.

[0034] like Figure 1 , Figure 2 and Figure 3 The high-speed maglev train ramp fault mechanical support parking device shown includes a mechanical shaft 1, a mechanical control device 1-1, a motor 1-2, a support frame 2, a support spring 3, a support plate 4, a support sleeve 4-1, a support panel 4-2 and a support groove 5.

[0035] As one or more implementation modes, the mechanical shaft 1 is a common steel structure, and can be driven by the motor 1-2 control or the mechanical connection control mode 1-1, and the rotation range of the mechanical shaft 1 is 30° to 60°. When the train is running on a slope, if the train loses power and slides due to a traction fault, the drive control of the mechanical shaft 1 is realized through the train fault sensing device, and the motor 1-2 can be controlled by the on-board power supply system to complete the fault stop, or the mechanical connection control 1-1 can be manually operated to complete the fault stop.

[0036] As one or more implementation modes, the support frame 2 is a connection structure between the mechanical shaft 1 and the support plate 4, and is made of steel material; the connection between the support frame 2 and the mechanical shaft 1 can be achieved by welding or bolting.

[0037] As one or more embodiments, the support spring 3 is an ordinary alloy spring or hydraulic spring, which is a connecting structure between the support frame 2 and the support plate 4, and mainly plays a buffering role to prevent unnecessary damage caused by excessive shock during the parking process of the train. The support plate 4 is composed of a support sleeve 4-1 and a support panel 4-2; the support sleeve 4-1 is used to protect the support spring 3; the support panel 4-2 is a steel structure or a combination of steel and rubber, which is the main force-bearing part of the mechanical parking device when the high-speed maglev train stops. The size of the support panel 4-2 is matched with the size of the support groove 5 on the track. When the train is in a ramp fault and slides, the support plate 4 contacts the support groove 5 on the track to form a supporting effect, combined with the buffering effect of the support spring 3, until the train stops sliding.

[0038] In this embodiment, the mechanical support parking device for high-speed maglev train ramp failure is distributed in two rows along the running direction of the train, with a spacing of more than 1m between the two rows and more than 2m between each row. The forward mechanical support parking device or the reverse mechanical support parking device is activated according to the specific sliding direction of the train during the specific working conditions of uphill failure and downhill failure. The mechanical support parking device for high-speed maglev train ramp failure needs to be used in conjunction with the support groove 5 on the track. The support groove 5 is made of ordinary steel material or concrete material and is distributed in the middle of the track.

[0039] As one or more implementation modes, the support frame 2 is fixed to the mechanical shaft 1 by welding or bolting, and is a connecting device between the mechanical shaft 1 and the support plate 4 .

[0040] As one or more implementation modes, the support spring 3 is a common alloy spring or a hydraulic spring, which is arranged between the support frame 2 and the support plate 4 and serves as a buffer structure when the train stops.

[0041] This embodiment provides emergency treatment for preventing casualties or train damage caused by the train sliding downhill when a slope failure is caused by a failure of the train traction system. The support parking function in the event of a slope failure is realized by mechanical connection, which can effectively reduce the harm of the slope failure and greatly improve the safety and reliability of the operation of high-speed maglev trains.
