Problems solved by technology

[0002] For some downward belt conveyors with a large inclination angle, the sliding force generated by the gravity of the material greatly exceeds the running resistance, so that the drive motor runs in the state of power generation, and when the brake is stopped, the sliding force all acts on the braking device On the other hand, it is easy to cause the brake device to fail and cause speeding, causing accidents such as running coal, hurting people, breaking the belt, and the motor rotor is broken.
In response to this situation, many brake devices have been developed at home and abroad. One of the brake devices that is more commonly used and has a better effect is the hydraulic speed control brake. The speed valve is used to adjust the braking force. At present, the maximum operating pressure of the domestic speed control valve is 28Mpa, and the high-pressure and large-flow hydraulic system should generally reach a pressure resistance of 35Mpa, so a base pressur

Embodiment Construction

[0012] The hydraulic variable speed soft brake is a subsystem that must be used in conjunction with the braked system (main system). The motor 5 of the main system is connected with the reducer 21 of the belt conveyor through a coupling 22, and the output shaft of the reducer 21 directly drives the driving roller 20 of the conveyor. The oil suction port and the oil discharge port of the brake pump 6 are connected to the hydraulic pump station 29 respectively. Manual reversing valve 9, pilot relief valve 8, electromagnetic reversing valve 7, proportional throttle valve 15, differential pressure reducing valve 14, fine filter 12, coarse filter 3, bypass valve 13, fuel tank 1, The pressure gauges 10 , 11 , the stop valve 2 , the flow sensor 19 and the rotational speed sensor 4 are all arranged in the hydraulic pump station 29 . The brake pump 6 is connected with the speed reducer 21 high-speed shaft of the tape machine through a shaft coupling 23, so that the main system drives ...

Abstract

A hydraulic speed regulation type soft brake for the underhung conveyer is composed of hydraulic system and electric control system. The said hydraulic system consists of braking pump and hydraulic pump station which comprises manual reverse valve, electromagnetic overflow valve, proportional throttle valve, filters, oil tank, pressure meter, cut-off valve and sensors (flow sensor and rotation speed sensor). Its advantages are high braking stability, and no need of cooler.

Description

Technical field [0001] The invention relates to a hydraulic speed regulating brake device. It is especially suitable for use in conjunction with mechanical systems that must be braked, such as conveyor belt conveyors. Background technique [0002] For some downward belt conveyors with a large inclination angle, the sliding force generated by the gravity of the material greatly exceeds the running resistance, so that the drive motor runs in the state of power generation, and when the brake is stopped, the sliding force all acts on the braking device On the other hand, it is easy to cause the brake device to fail and cause speeding, causing accidents such as running coal, hurting people, broken belts, and motor rotors being damaged. In response to this situation, many brake devices have been developed at home and abroad. One of the brake devices that is more commonly used and has a better effect is the hydraulic speed control brake. The speed valve is used to adjust the brak...
