[0002] In the field of railway transportation, the safe parking and starting of EMUs are of vital importance. Traditional wheel stoppers rely mainly on manual placement and removal during operation, which is not only labor-intensive and inefficient, but also prone to safety hazards due to human negligence. For example, in severe weather conditions, the accuracy and timeliness of manual operation will be seriously affected, thus threatening the safety of EMUs.

[0003] With the continuous increase in the speed of EMUs and the continuous increase in transportation density, higher requirements are placed on the intelligence and automation of wheel stoppers. The existing partially automated wheel stoppers are difficult to meet the use requirements of different types of EMUs due to their poor compatibility with the EMU tracks and vehicle structures. At the same time, these devices lack monitoring and fault warning functions, and cannot provide real-time feedback on the working status of the wheel stoppers, and cannot detect and solve potential problems in advance, which seriously restricts the safety and reliability of railway transportation.

[0004] To solve the above problems, we propose an intelligent wheel stopper that can adapt to different EMUs and has intelligent control, real-time monitoring and fault warning functions to meet the railway industry's needs for safe and efficient transportation. Summary of the invention

[0037] See also Figure 1-Figure 5 The present invention provides a technical solution: an intelligent wheel stopper for an EMU, comprising a base 1, a wheel stopper plate 2 and an actuator 5 adapted to the EMU track 11 and the vehicle structure. The middle part or one end of the wheel stopper plate 2 is hinged to the connecting rod 3 through a pin shaft. The connecting rod 3 is installed on a slider 4. The slider 4 is connected to the actuator 5. The actuator 5 drives the slider 4 to move, driving the connecting rod 3 to rotate the wheel stopper plate 2 around the hinge point, thereby realizing the locking and releasing switching of the wheel stopper on the EMU wheel 13. The size and installation interface of the base 1 meet the relevant standards of the EMU.

[0038] In this embodiment, the actuator 5 includes a drive unit 501 and a push rod 502. The drive unit 501 drives the push rod 502 to perform telescopic linear motion, thereby driving the slider 4 to move. The drive unit 501 is provided with an intelligent control module, which can automatically control the movement of the push rod 502 according to the EMU control signal, and output the push rod 502 push stroke to the EMU monitoring system.

[0039] Specifically, the drive unit 501 of the actuator 5 is equipped with an intelligent control module, which can automatically control the action of the push rod 502 and output the travel information according to the EMU control signal. This design enables the wheel stopper to achieve automatic control, greatly reducing manual operation and labor costs. At the same time, the accuracy of the wheel stop operation is improved through travel feedback, ensuring that the wheel stop effect is stable and reliable.

[0040] In this embodiment, the drive unit 501 is hydraulically driven or electrically driven, and accurately controls the movement of the push rod 502 by communicating with the central control system of the EMU, and feeds back the status information of the push rod 502 to the central control system, thereby realizing intelligent monitoring and fault warning.

[0041] Specifically, the drive unit 501 is hydraulically or electrically driven and communicates with the EMU central control system, which can not only accurately control the action of the push rod 502, but also feedback its status information. On the one hand, it realizes the refined control of the wheel stopper action, and on the other hand, through the real-time grasp of the equipment status, it can timely discover and solve potential fault hazards, realize intelligent monitoring and fault warning, and ensure railway transportation safety.

[0042] In this embodiment, the actuator 5 is connected to the upper control host of the EMU, and the upper control host remotely controls the action of the actuator 5, monitors its status in real time, and judges the working status of the wheel stopper through the status of the actuator 5, the push rod 502 and the position of the slider 4, and issues an alarm when an abnormality occurs.

[0043] Specifically, the actuator 5 is connected to the upper control host to achieve remote control and real-time status monitoring. The staff can remotely operate the wheel stopper, breaking through the space limitation and improving the convenience of operation. At the same time, with the comprehensive judgment of the actuator status, push rod and slider position, the working status of the wheel stopper can be more comprehensively grasped, and an alarm can be immediately issued in case of abnormality, further enhancing the safety and reliability of railway transportation.

[0044] In this embodiment, the base 1 includes a bottom plate 101, a guide rail 102 and a support seat 103. The guide rail 102 and the support seat 103 are installed on the bottom plate 101. One end of the wheel stop plate 2 is hinged to the support seat 103. The guide rail 102 is arranged along the movement direction of the slider 4 for the slider 4 to slide on top. The bottom plate 101 is provided with a fixed structure connected to the EMU track or car body.

[0045] Specifically, the base 1 adopts a combination design of a bottom plate 101, a guide rail 102 and a support seat 103, the wheel stop plate 2 is hinged to the support seat 103, the slider 4 moves along the guide rail 102, and the bottom plate 101 is provided with a fixed structure. This design provides a stable installation and movement platform for each component, ensures that the wheel stopper has a stable structure during operation, and improves the reliability and durability of the wheel stopper.

[0046] In this embodiment, when the slider 4 is in the extreme movement position, it is tightly fitted with the support seat 103. The extreme position is fed back to the EMU control host through the sensor in the wheel stopper to determine the locking state of the wheel stopper.

[0047] Specifically, the limit position of the slider 4 is tightly matched with the support seat 103, and the feedback is sent to the control host through the sensor to determine the locking state of the wheel stopper. This design provides an intuitive and accurate basis for judging whether the wheel stopper is locked normally, helping the staff to understand the working state of the wheel stopper in time and avoid safety accidents caused by abnormal locking.

[0048] In this embodiment, the base plate 101 is provided with a lug plate 104 for mounting the actuator 5, which is mounted in a manner that facilitates connection with the electrical and hydraulic systems of the EMU;

[0049] Specifically, the ear plate 104 on the bottom plate 101 is used to install the actuator 5, and the installation method is convenient for connecting with the electrical and hydraulic systems of the EMU. This design optimizes the connection method between the wheel stopper and the EMU-related systems, facilitates construction and installation and later maintenance, and improves the integration of the wheel stopper and the EMU system.

[0050] In this embodiment, a first mounting groove is provided at one end of the slider 4 to connect the connecting rod 3, and a second mounting groove is provided at the other end to connect the actuator 5, so as to ensure the connection reliability and maintainability, and facilitate the rapid disassembly and installation during the maintenance of the EMU;

[0051] Specifically, the mounting grooves at both ends of the slider 4 are respectively connected to the connecting rod 3 and the actuator 5, ensuring the reliability and maintainability of the connection. When the EMU is overhauled, the staff can quickly disassemble and install related components, shorten the overhaul time, improve the overhaul efficiency, reduce the equipment downtime, and ensure the normal operation of railway transportation.

[0052] In this embodiment, a dovetail groove 401 is provided at the bottom of the slider 4 to cooperate with the guide rail 102. The size and precision of the dovetail groove 401 meet the requirements of the EMU operating environment, ensuring that the slider 4 slides smoothly;

[0053] Specifically, the dovetail groove 401 at the bottom of the slider 4 cooperates with the guide rail 102, and the size and precision meet the requirements of the EMU operating environment, ensuring the smooth sliding of the slider 4. This design improves the stability of the wheel stopper, reduces the failure caused by the unsmooth movement of the slider 4, and prolongs the service life of the wheel stopper.

[0054] In this embodiment, a method for using an intelligent wheel stopper for a train set includes:

[0055] Startup step: When the EMU needs to stop, the EMU control host sends a start signal to the actuator 5, and the drive unit 501 starts working;

[0056] Locking steps: the driving unit 501 drives the push rod 502 to extend, pushing the slider 4 to move along the guide rail 102, the slider 4 drives the connecting rod 3, so that the wheel stop plate 2 rotates around the hinge point, the wheel stop part is lowered and contacts the EMU wheel 12, and locking is achieved;

[0057] Monitoring steps: During the locking process, the actuator 5 feeds back the status information such as the stroke of the push rod 502 and the position of the slider 4 to the EMU control host in real time, and the control host determines whether the wheel stopper works normally;

[0058] Release steps: When the EMU needs to start, the EMU control host sends a release signal to the actuator 5, the drive unit 501 drives the push rod 502 to retract, the slider 4 moves in the opposite direction, drives the connecting rod 3 to rotate the wheel stop plate 2 around the hinge point, the wheel stop part is lifted, and the lock on the wheel 12 is released;

[0059] Stopping step: After the wheel stopper completes the release action, the driving unit 501 stops working and waits for the next instruction.

[0060] The working principle of the above embodiment is as follows: when the EMU needs to stop, the EMU control host plays a role and sends a start signal to the actuator 5. After receiving the signal, the drive unit 501 in the actuator 5 starts to work and provides power support for subsequent actions. This is the starting link of the entire working process;

[0061] After the driving unit 501 starts working, the driving push rod 502 extends, and the extension of the push rod 502 pushes the slider 4 to move along the guide rail 102 installed on the base 1. The slider 4 drives the connecting rod 3 during the movement, and the middle part or one end of the wheel stop plate 2 is hinged to the connecting rod 3 through a pin shaft, so the movement of the connecting rod 3 causes the wheel stop plate 2 to rotate around the hinge point, and the wheel stop part of the wheel stop plate 2 is lowered and contacts the EMU wheel 12, thereby locking the EMU wheel to prevent the EMU from moving when docked; during the locking process, the actuator 5 undertakes an important information feedback task, and it feeds back the state information such as the stroke of the push rod 502 and the position of the slider 4 to the EMU control host in real time. After receiving this information, the EMU control host analyzes and processes it to determine whether the wheel stopper works normally. If an abnormal situation occurs, the control host can take corresponding measures in time, such as issuing an alarm; when the EMU needs to start, the EMU control host sends a release signal to the actuator 5. After receiving the release signal, the drive unit 501 drives the push rod 502 to retract. The retraction of the push rod 502 causes the slider 4 to move in the opposite direction, and the reverse movement of the slider 4 drives the connecting rod 3, thereby causing the wheel stop plate 2 to rotate around the hinge point, and the wheel stop portion of the wheel stop plate 2 is lifted, releasing the lock on the wheel 12, and removing the restriction on the start of the EMU. After the wheel stopper completes the release action, the drive unit 501 stops working. At this time, the wheel stopper is in a standby state, waiting for the next instruction from the EMU control host, so as to perform the corresponding operation again when needed.

[0062] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
