Description

Technical Field

[0001] The present invention belongs to the technical field of APM vehicle braking systems, and more specifically, relates to an APM vehicle spring brake relief device. The present invention also relates to a method for using the APM vehicle spring brake relief device. Background Art

[0002] The braking system of APM vehicles (Automated People Mover System) adopts electric-pneumatic hybrid braking, and friction braking adopts air braking. The braking system is active safety. The brake cylinder of the friction brake actuator has two independent air chambers, namely the brake air chamber and the spring air chamber. The brake air chamber is inflated for braking and exhausted for relief; the spring air chamber is inflated for relief and exhausted for braking. During normal operation, the application and relief of the brake are achieved by the inflation and exhaust of the brake air chamber, and the spring air chamber is always inflated. When there is no air in the braking system due to a fault condition or after the vehicle has been parked for a long time, the spring brake is applied to ensure the safety of the vehicle.

[0003] The friction brake system is equipped with an auxiliary relief air cylinder, which is used to relieve spring brakes, and is used to relieve brakes and apply rescue in fault conditions or rescue conditions. The defects of the prior art are: APM vehicles adopt active safety braking, and the brake cylinder is divided into two independent air chambers. The spring air chamber is used as a safety guarantee. When exhausting, the brake is applied by spring force, and when inflating, the air pressure overcomes the spring force to relieve the brake. When the vehicle needs to be rescued due to a fault, the driving mode of the faulty vehicle will be changed to manual mode. At this time, the hand control handle is in the EB position, the faulty vehicle will apply emergency braking, and the emergency solenoid valve will lose power. The brake air chamber can be exhausted through the brake relief device in the passenger compartment, and the spring air chamber will also be exhausted due to the loss of power of the emergency solenoid valve. At this time, operating the button on the hand control cannot relieve the spring brake, and the operator can only get off the vehicle and operate on the brake equipment. Because the APM vehicle is powered by the third rail, if the operator enters the track area, the power supply rail needs to be powered off, which will seriously affect the normal operation of the vehicle, and the operator has a major safety hazard.

[0004] There is a technology in the prior art named "An air brake system for APM vehicles" and with a publication (announcement) number of "CN102963347B", which discloses an air brake system for APM vehicles. In order to solve the problem that the existing air brake system does not have the brake control, brake monitoring and fault diagnosis functions, the APM vehicle air brake system includes an air supply module, an air control module, a brake control module, a basic brake device air circuit control module, an air spring air circuit control module, and an unhooking and vehicle connection pipeline control module. The air brake system described in the present invention has a more flexible brake cylinder pressure adjustment capability than the original technology, and has better control accuracy and functional expansibility. This technology does not involve the technical problems and technical solutions of the present application. Summary of the invention

[0005] The technical problem to be solved by the present invention is: in view of the deficiencies in the prior art, an APM vehicle spring brake relief device is provided which has a simple structure and can complete vehicle brake relief in the passenger compartment under vehicle rescue conditions. The operator does not need to enter the trackside to perform operations under the vehicle. The operator can complete related operations while ensuring that the power supply rail is uninterrupted. This not only ensures the personal safety of the operator and improves work efficiency, but also minimizes the impact on operations.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is:

[0008] The zipper component support of the zipper component is connected to the electrical cabinet bracket, and the other end of the zipper connector is connected to the manual valve component.

[0009] The manual valve assembly comprises a manual valve body, a manual valve handle, and a zipper fixing device. The manual valve body is a two-position three-way valve, the manual valve handle is connected to the manual valve body, the zipper fixing device is connected to the manual valve handle, and the zipper connector of the zipper assembly is connected to the zipper fixing device.

[0010] The APM vehicle spring brake relief device also includes a pulley assembly, which includes a pulley assembly support, a zipper protection tube mounting plate, a sleeve, a pulley assembly pin, and a pulley assembly latch. The pulley assembly pin is connected to the pulley assembly support, the sleeve is connected to the pulley assembly pin, the zipper protection tube mounting plate is connected to the pulley assembly pin, the pulley assembly latch is connected to the pulley assembly pin, and the pulley assembly support is connected to the vehicle chassis.

[0013] The present invention also relates to a method for using an APM vehicle spring brake relief device, which has simple steps and can complete vehicle brake relief in the passenger compartment under vehicle rescue conditions. An operator does not need to enter the trackside to perform operations under the vehicle. The operator can complete related operations while ensuring that the power supply rail is not disconnected. This not only ensures the personal safety of the operator and improves work efficiency, but also minimizes the impact on operations. The method for using the APM vehicle spring brake relief device has the following steps:

[0014] S1: destroy the lead seal of the handle latch protection device and the handle latch, lift the handle latch protection device, take the handle latch out from the opening of the handle and the opening of the handle seat, connect the handle latch to the handle seat through the anti-drop device, insert the handle latch into the zipper to form a support to complete the fixation;

[0015] S2: Lift the handle to the limit position and rotate it 90 degrees.

Under non-vehicle rescue conditions, the handle latch passes through the opening of the handle seat and the opening of the handle, and the handle latch protection device and the handle latch are connected through the lead seal. At this time, the handle latch protection device fixes the handle and the handle seat through the lead seal, and one end of the zipper connector passes through the zipper support rod and is connected to the handle. The zipper connector is used to transmit force to the manual valve assembly when operating the handle. The zipper assembly support of the zipper assembly is connected to the electrical cabinet bracket, the electrical cabinet bracket fixes the zipper assembly bracket, and the other end of the zipper connector is connected to the manual valve assembly. The structure of the present invention includes: a zipper assembly, a pulley assembly, and a manual valve assembly. The zipper assembly connector is a wire rope structure.

When the spring brake needs to be isolated, the lead seal is released, and then the manual valve handle can be controlled by the operating handle. By pulling up the manual valve handle of the zipper assembly, the manual valve handle can be pulled by the wire rope to switch the manual valve body to the conduction position, which assists in relieving the compressed air in the air cylinder from entering the spring air chamber and completes the relief of the spring brake. The structure of the present invention can achieve the relief of vehicle brakes in the passenger compartment under the vehicle rescue condition, and the operator does not need to enter the trackside to work under the vehicle. Since the APM vehicle is powered by the third rail, the operator can complete the relevant operations while ensuring that the power supply rail is not disconnected, which not only ensures the personal safety of the operator and improves the work efficiency, but also minimizes the impact on operations.
