Description

Technical Field

[0001] This utility model relates to the field of rail transit vehicle braking technology, and in particular to a remote release control system for parking brakes of rail vehicles. Background Technology

[0002] Currently, in order to meet the parking braking force requirements of rail vehicles, the basic braking system of the vehicle is usually equipped with a parking brake device. The parking brake device mainly includes spring force application and air release. In order to ensure that the vehicle releases the parking brake in the absence of air, the basic braking system is equipped with a manual mechanical release device to release the spring parking braking force generated by the parking brake device.

[0003] Traditionally, the manual release rope of the parking brake device is located near the wheel. When the parking brake force needs to be released, the operator needs to pull the manual release rope to release it. When the parking brake force is large, a lot of force needs to be used under the car to pull out the release ring. In addition, the traditional rope has a large pull force attenuation, high resistance, and limited length, making it very inconvenient to operate. This poses a great safety hazard to the operator, especially for rail vehicles with third rail current collection.

[0004] In addition, the traditional method uses a steel cable to connect the release lever, with the handle at the other end of the cable usually placed on both sides of the vehicle. Pulling the handle can release the parking brake. The brake cylinders with parking function are usually located on both sides of the vehicle. This method can only release the parking brake on one side at a time under the vehicle. Releasing both parking cylinders requires two operations, and can only be done under the vehicle. The release force is large, the operation is time-consuming, and the status is not easy to identify.

[0005] Therefore, it is necessary to provide a remote release control system for parking brakes of rail vehicles that can release the parking brake on a bogie in a single operation. Utility Model Content

[0006] The purpose of this utility model is to overcome the defects of the existing technology and provide a remote release control system for parking brakes of rail vehicles that has a reasonable layout, can release the parking brake of one bogie at a time on or under the vehicle, is labor-saving to operate, and is convenient to maintain.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The remote release control system for parking brakes of rail vehicles disclosed in this utility model includes:

[0009] Two parking brake cylinders, and rotary handles respectively located on and under the vehicle for independently releasing the parking brake cylinders; and

[0010] An integrated box for force amplification, which is connected to the two parking brake cylinders and the two rotary handles respectively via push-pull cables; also includes...

[0011] A transition bracket is fixedly connected to the vehicle frame and supports the integrated box to form an operating space with the vehicle's underframe. The transition bracket is detachably and fixedly connected to the integrated box on the side away from the underframe.

[0012] Furthermore, the transition bracket is detachably and securely connected to the vehicle frame and the integrated box via connectors.

[0013] Furthermore, the handle under the vehicle is fixedly connected to the side beam of the underframe via the transition bracket.

[0014] Furthermore, the rotating handle located under the vehicle is situated on one side of the vehicle body, while the rotating handle located on the upper part of the vehicle is situated on the other side inside the vehicle body.

[0015] Furthermore, the parking release mechanism inside the parking brake cylinder is equipped with a limit switch. The mechanical release of the parking brake will trigger the limit switch, output a status signal, and display it on the indicator lights inside and outside the vehicle.

[0016] The remote release control system for parking brakes of rail vehicles provided by this utility model has the following advantages:

[0017] The rail vehicle parking brake remote release control system designed in this utility model firstly uses an integrated box that can amplify force to connect two parking brake cylinders via push-pull cables, and connects two rotary handles that can independently control the two parking brake cylinders via two push-pull cables at the output end, which facilitates independent operation on and off the vehicle.

[0018] Secondly, the integrated box is hoisted using a transition bracket, creating an operating space between the integrated box and the frame. This allows both new vehicles not yet on the line and vehicles already in operation to be technically modified according to user needs to apply the remote release control system for rail vehicle parking brake. The integrated box and rotary handle have a sufficiently expansive field of vision for connection and disassembly, as well as adjustment of the pull-pull stroke, during installation, disassembly, and subsequent maintenance.

[0019] The remote release control system for parking brakes of this rail vehicle is flexible and reasonable in layout and application. It allows for multi-point tension output operation on and off the vehicle, simplifies the control system, reduces the number of system components, and integrates functional components, effectively reducing the failure rate and cost and improving reliability.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] Figure 1 A structural diagram of a remote release control system for parking brakes of rail vehicles;

[0030] Figure 2 Schematic diagram of the onboard status structure of the remote release control system for parking brakes of rail vehicles;

[0031] A utility model remote release control system for parking brakes of rail vehicles includes: two parking brake cylinders 1, two rotary handles 2, and an integrated box 4;

[0032] Two rotary handles 2 are respectively located on the upper and lower parts of the vehicle. An integrated box 4 is used for force amplification. The sides of the integrated box 4 are connected to two parking brake cylinders 1 and two rotary handles 2 via push-pull cables 3, allowing the two rotary handles 2 to independently release the parking brake cylinders 1. In other words, as... Figure 2As shown, the integrated box 4 and the rotating handle 2 are connected by a push-pull cable 3b, and the integrated box 4 and the parking brake cylinder 1 are connected by a push-pull cable 3a. During assembly, refer to... Figure 1a The male connector 3.1 and female connector 3.2 of the push-pull cable 3 are connected by a joint. The integrated box 4 is a product of the existing VPS model B200-298. It uses the lever amplification principle to amplify the output of the pulling force. The push-pull cable 3 is a push-pull cable of the existing VPS models F71448 and F71449. It uses a ball bearing slide to transmit the push-pull force, and the efficiency can reach more than 90%.

[0033] See Figure 2 , 3 As shown:

[0034] The remote release control system for parking brakes of rail vehicles also includes a transition bracket 5;

[0035] The transition bracket 5 is fixedly connected to the vehicle frame and supports the integrated box 4 and the vehicle's chassis 6 to form an operating space. The side of the transition bracket 5 away from the chassis 6 is detachably fixedly connected to the integrated box 4. In this structure, the transition bracket 5 ensures that there is sufficient installation and operating space between the integrated box 4 and the vehicle chassis 6, which facilitates the installation, disassembly and maintenance of the integrated box 4, and provides sufficient travel space for torque application to ensure the reliability of the integrated box 4 installation. At the same time, it facilitates the operation of connecting the push-pull lock to the integrated box 4. When the push-pull lock cylinder and the pull rod of the integrated box 4 need to be coupled, there is a wide field of vision for connection and disassembly, as well as adjustment of the push-pull stroke of the lock. In the working state, it is beneficial for the push-pull lock cylinder to push and pull relative to the housing, driving the lever mechanism inside the integrated box 4 to rotate, realizing the effective transmission of the push-pull stroke of the push-pull lock cylinder and the amplification of the force.

[0036] The transition bracket 5 is detachably and fixedly connected to the vehicle frame and the integrated box 4 via the connector 8. Specifically, the connector 8 is a bolt assembly, which facilitates the subsequent disassembly and assembly of the integrated box 4. The transition bracket 5 has a U-shaped structure, and the vertical section of the U-shape of the transition bracket 5 is provided with mounting holes for mounting the bolt assembly.

[0037] See Figure 2 , 4 As shown:

[0038] The undercarriage handle is fixedly connected to the chassis side beam 7 via a transition bracket 5. Specifically, the transition bracket 5 has a U-shaped structure with horizontal sections on both sides and in the middle. These horizontal sections have openings for mounting connectors 8, thus ensuring a secure connection between the two sides of the transition bracket and the chassis side beam, and a secure connection between the middle of the bracket and the rotating handle 2. Similarly, in this structure, the rotating handle 2 is mounted on the chassis via the transition bracket 5, ensuring sufficient installation and operating space between the undercarriage rotating handle 2 and the vehicle chassis 6. This provides a clear view for connection and disassembly when the push-pull lock cylinder and the rotating handle 2 lever need to be coupled, as well as for adjusting the push-pull stroke. In operation, this facilitates the rotation of the handle relative to the housing, enabling effective transmission of the push-pull lock cylinder's stroke and secondary force amplification.

[0039] The vehicle-mounted rotary handle 2 is located inside the vehicle, and the vehicle-mounted rotary handle 2 is installed at the interface position reserved in the vehicle via a connecting bracket.

[0040] Preferably, the under-vehicle rotary handle 2 is located on one side of the vehicle body, and the upper-vehicle rotary handle 2 is located on the other side inside the vehicle body. Specifically, for example... Figure 2 As shown, facing the direction of vehicle movement, the under-vehicle rotary handle is located on the left side of the vehicle body, while the upper-vehicle rotary handle is located on the right side inside the vehicle, making operation convenient;

[0041] Preferably, the parking release mechanism in the parking brake cylinder 1 is equipped with a limit switch. The mechanical release parking process will trigger the limit switch, output a status signal, and display it on the indicator lights inside and outside the vehicle.

[0042] In the above technical solution, the rail vehicle parking brake remote release control system provided by this utility model is as follows:

[0043] 1. Flexible layout: The position of the parking brake rotary handle 2 inside and outside the vehicle can be set according to the user's operating needs and habits. This allows the driver and operator to quickly and mechanically release the parking brake of one bogie (two parking brake cylinders 1) from any position inside or outside the vehicle. The operation frequency is reduced and the operation position is flexible and convenient. The operating position of the handle can also be changed according to the user's needs for vehicles already in operation. It is suitable for the renovation of old operating vehicles and can be flexibly arranged in areas with limited installation and operating space.

[0044] 2. Low failure rate: The optimized internal structure of the integrated box 4 allows for adjustment of the shape and size of the force amplification lever. Based on the traditional bogie parking brake cylinder 1 structure, there is no need to change the structure of the parking brake cylinder 1 or the mechanical release cable interface. The quick-release ball head at one end of the push-pull cable 3 can be directly connected to the mechanical release cable interface inside the parking brake cylinder 1, and the quick-release ball head at the other end of the push-pull cable 3 can be directly connected to the integrated box 4. The coupling of the male and female ball heads realizes the connection of the lock cylinder structure, eliminating the need for an externally installed mechanical release mechanism for the mechanical release of the parking cylinder under the vehicle, as required by the existing system. At the same time, the second rotating handle 2 led out from the integrated box 4 under the vehicle can be installed under the vehicle. Alternatively, according to user needs, if one handle is already configured on the vehicle, a handle can be set under the vehicle to achieve dual-sided mechanical release parking. This allows one bogie parking brake to release two parking brake cylinders 1 at once, reducing the number of control components. The same integrated box 4 can realize the integrated amplification of multiple load tension inputs and multi-point tension output operations, simplifying the control system, reducing the number of system components, improving the integration of functional components, reducing failure rate and cost, and improving reliability.

[0045] 3. Flexible application: The push-pull cable 3, used for remote control of parking machinery, employs a ball bearing slide to transmit push-pull force, achieving a mechanical efficiency of over 90%. The push-pull cable 3 is flexible and has a minimum bending radius of 100mm, making it suitable for installation and fixing in confined and complex spaces. Secured using traditional nylon tubing clamps found in rail vehicles, the push-pull cable 3 can be extended to the required operating position without sacrificing mechanical efficiency. The connection between the push-pull cable 3 and the parking brake cylinder 1 can be designed according to the interface type.

[0046] 4. To facilitate identification by drivers and maintenance personnel, the parking release mechanism inside the parking brake cylinder 1 is equipped with a limit switch. The push-pull cable 3 of the mechanical release parking operation will trigger the limit switch, output a status signal, and display it on the indicator lights or display screen inside and outside the vehicle.

[0047] 5. Effortless: The parking brake remote release control system achieves double force amplification through the force amplification mechanism of the integrated box 4 and the rotary handle 2. The specific force amplification factor can be designed according to user requirements, making it easy for female drivers and operators to operate.

[0048] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
