Description

Technical Field

[0001] The invention belongs to the technical field of rail transit vehicle braking, and in particular relates to a parking brake relief device. Background Art

[0002] In the rail transit vehicle braking system, parking brake is an important function to ensure that the vehicle can be parked reliably for a long time without external energy supply. The parking brake function includes brake application function and parking brake release function.

[0003] The traditional parking brake release method is to release it by manually pulling the rope. The operator must reach the side of the bogie and pull the hand ropes one by one to disengage the ratchet mechanism inside the brake to achieve parking brake release. Each brake needs to be pulled once, and each time it takes about 300N to 500N of force. Based on 4 brakes per car, a train of 6-carriage subway cars needs to be pulled 24 times. The operation is very inconvenient, time-consuming and labor-intensive. The disadvantages of this function are particularly prominent when the car formation is long. Summary of the invention

[0004] The present invention aims to solve the problems of inconvenient operation and low efficiency of the traditional parking brake relief function, thereby providing a parking brake relief device, which adopts an electric method to power on the parking relief mechanism on the brake, and can remotely and quickly complete the parking brake relief function of the brake, thereby freeing up manpower and improving operating efficiency.

[0005] To achieve the above-mentioned purpose of the invention, the present invention provides a parking brake release device, including a quick-connect connector, a retractable cable, a chassis, a switch, a display, a release operation button, a cable reel, a battery pack, a main control board, and an adapter board; a battery pack, a main control board and an adapter board are arranged in the chassis, the battery pack is connected to the main control board, the connection switch, the display and the release operation button are installed on the adapter board, the adapter board is at the front end of the chassis, and the connection switch, the display and the release operation button extend from the opening at the front end of the chassis; the adapter board and the main control board are connected through a connector; a cable reel is provided on the inner side of the rear end of the chassis, one end of the cable reel is connected to the main control board, and the other end is connected to the quick-connect connector on the outside of the chassis through a retractable cable.

[0006] Furthermore, the battery pack includes a battery group and a protective shell, and the battery pack is integrated on the main control board.

[0007] Furthermore, the connection switch, display and relief operation button are electrically connected to the main control board via an adapter board.

[0008] The operator of the present invention only needs to hold the invention device of the present patent, connect the device to the parking brake release interface by quick plugging inside the vehicle, and operate the release button to complete the parking brake release of all brakes of a vehicle within 5 seconds. Compared with the traditional solution, this solution has the advantages of easy operation, high efficiency, and labor saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Among them: 1. Quick-connect connector; 2. Retractable cable; 3. Chassis; 4. Switch; 5. Display; 6. Relief operation button; 7. Cable reel; 8. Battery pack; 9. Main control board; 10. Adapter board; 11. Brake. DETAILED DESCRIPTION

[0013] In order to better understand the purpose, structure and function of the present invention, a parking brake release device of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0014] Reference Figure 1 The device is mainly composed of a quick-plug connector 1, a retractable cable 2, a chassis 3, a switch 4, a display 5, a relief operation button 6, a cable reel 7, a battery pack 8, a main control board 9, and an adapter board 10. A plurality of quick-plug connectors 1 and retractable cables 2 can be provided.

[0015] A battery pack 8, a main control board 9 and an adapter board 10 are arranged in the chassis 3. The battery pack is connected to the main control board. The connection switch 4, the display 5 and the relief operation button 6 are installed on the adapter board. The adapter board is at the front end of the chassis 3. The connection switch 4, the display 5 and the relief operation button 6 extend from the opening at the front end of the chassis; the adapter board 10 and the main control board 9 are connected through a connector.

[0016] The cable drum 7 is mounted on the inner side wall of the rear end of the chassis 3 for storing the retractable cable 2. One end of the cable drum 7 is connected to the main control board 9, and the other end is connected to the quick-plug connector 1 outside the chassis 3 through the retractable cable 2, and the quick-plug connector is used to connect to the brake under the vehicle.

[0017] The battery pack 8 is composed of a battery group and a protective shell, which can effectively protect the battery and prevent the battery from affecting other components when it fails. The battery pack 8 is integrated on the main control board 9 and is used for storing electric energy.

[0018] The main control board 9 integrates the battery charging circuit, which has the functions of filtering protection, surge suppression, charging current control, charging voltage control, etc., to protect the battery charging safety. In addition, the control board can control the battery voltage to prevent the battery from overvoltage failure and extend the service life. The power and fault status are displayed on the display.

[0019] The switch 4 , the display 5 and the relief operation button 6 are electrically connected to the main control board 9 via the adapter board 10 .

[0020] When working, the quick-connect connector 1 is connected to the brake 11 through the parking brake release interface on the vehicle, and the release operation button 6 is operated to energize the parking release mechanism inside the brake. The device has a timing function. After pressing the release operation button 6, the timing automatically starts. After reaching the preset time, the external output power supply is automatically cut off, and the operator is reminded by a buzzer. The device has a power and status display function, and displays relevant information through the display 5.
