Embodiment Construction
[0056] The track brakes in the prior art have complex structures and high manufacturing costs, are difficult to meet the requirements in the specifications, have low performance reliability, and are prone to safety hazards.
[0057] In order to improve the above problems, the present invention provides a hydraulic track brake and a braking system. The hydraulic track brake includes a bracket, a clamp arm, a wedge block and a disc spring hydraulic cylinder. The hydraulic track brake system includes a main control subsystem, an electrical The control subsystem, the hydraulic subsystem and at least two hydraulic track brakes, through the modular design of the track brakes, according to the parameters of a single track brake and the slope and total weight of the cable car, are calculated in accordance with the requirements of the specification, and the number of track brakes is calculated. The configuration can effectively realize the rational use of track brakes, and the structure...

The invention provides a hydraulic track brake and a hydraulic track brake system, belonging to the field of ground cable cars. The hydraulic track brake comprises a support, two tong arms, a wedge block and a disc spring hydraulic cylinder. The hydraulic track brake system comprises a main control subsystem, an electric control subsystem, a hydraulic subsystem and at least two hydraulic track brakes. By carrying out modularized design on the track brakes and calculating based on standard requirements according to the parameters of the single track brake as well as the gradient and gross weight of a cable car, the quantity of the track brakes is configured, the reasonable utilization of the track brakes can be effectively realized, and the structure is simple and convenient. In addition, a plurality of groups of brakes sequentially act, firstly, few hydraulic track brakes are used for decelerating the cable car, and then a plurality of groups of hydraulic track brakes are used for stopping the cable car, thereby avoiding too fast braking, reducing friction loss and prolonging the service life of the hydraulic track brakes and tracks.
Description
technical field [0001] The invention relates to the field of ground cable cars, in particular to a hydraulic rail brake and a braking system. Background technique [0002] Passenger ground cable cars need to use track brakes to brake the cable car, etc., the requirements of Article 8.6 of "Passenger Ground Cable Car Safety Requirements (GB19402-2012)" are as follows: 8.6.2 In the following cases, the track brakes should be automatically activated: the traction cable breaks ; - to overspeed up to 25%; when the traction cable of the traveling mechanism is only half of its maximum tension or the tension of the traction cable is below 5KN. [0003] 8.6.3 When the vehicle has a crew member, the track brake should have a manual release device. The manual release should be in the same position as the automatic release of the brake shown. [0004] 8.6.4 When the track brake works on the track, the pressure of the track brake jaw should be determined according to μmin (preferably 0...
