Abstract

The invention discloses an emergency brake release system. The emergency brake release system comprises a battery, a brake controller and an emergency hydraulic brake. The battery provides power for the emergency hydraulic brake. The brake controller issues a control signal to control the emergency hydraulic brake to work, and a hoisting mechanism releases weights during power failures. The invention further provides a control method of the emergency brake release system. The control method comprises the steps that the system is started for self-inspection; the emergency brake release system is started; an emergency oil pump is started; the brake is switched off in an emergency manner; a speed sensor detects the rotating speed of a hoisting motor and uploads the rotating speed to the brakecontroller; the brake controller controls a proportional overflow valve to guarantee the rotating speed of the hoisting motor; and if the rotating speed of the hoisting motor is larger than a threshold value, the battery and the emergency brake release system are immediately disconnected, and the brake is switched on. The invention further provides the hosting mechanism including the emergency brake release system and the control method. It can be guaranteed that the hoisting mechanism releases the weights safely, fast and controllably when the system is powered off, the structure is simple,and safety and reliability are achieved.

Description

technical field [0001] The purpose of the present invention is to provide an emergency brake release system, a control method and a hoisting system thereof. Background technique [0002] With the development of national economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source in people's daily production and life, bringing endless convenience to people's production and life. [0003] The hoisting mechanism is an important auxiliary mechanism in industrial production, and the existing hoisting mechanisms all adopt electro-hydraulic control. The hydraulic disc brake is a device used for braking in the hoisting mechanism. When the hoisting mechanism decelerates and stops during normal operation, it can reliably realize the braking brake of the hoisting mechanism; in case of emergency, it can respond quickly, The lifting mechanism is braked by the brake; when the lifting mechanism stops working,...
