Embodiment Construction

[0017] Example. A safety braking method for an escalator, characterized in that a sensor is used to detect abnormal conditions of the escalator and / or passengers, the feedback signal of the sensor is transmitted to the control cabinet to cut off the power supply of the motor for braking, and the sprocket connected to the motor is activated. Locking brakes.

[0018] The method of using a sensor to detect the abnormal condition of the escalator and transmitting the feedback signal of the sensor to the control cabinet to cut off the power supply of the motor for braking is to detect the breakage or elongation of the step chain and the breakage or elongation of the drive chain through the induction switch , step sag, apron plate deformed by force or comb plate moved backward, the feedback signal of the induction switch is transmitted to the control cabinet to cut off the motor power and brake the motor through the brake.

[0019] The method for braking the cascade is that the kic...

Abstract

The invention discloses a safety braking method of an automatic escalator, which is characterized by comprising the following steps of: adopting a sensor to detect the abnormal condition of the automatic escalator and / or passengers, transmitting feedback signals of the sensor to a control cabinet to cut off a power supply of a motor for braking, and carrying out locked braking on a chain wheel connected with the motor. In the invention, a double-braking mode is adopted for the occurring abnormal condition of the automatic escalator and the passengers, so that the inverse operation of the escalator is avoided and the safety of the passengers is ensured.

Description

technical field [0001] The invention relates to a braking method and device, in particular to a safety braking method and device for an escalator. Background technique [0002] At present, with the development of social economy, escalators have been gradually integrated into people's lives, and are widely used in public places such as shopping malls and overpasses. [0003] The transmission structure of the escalator is mainly driven by the motor to drive the sprocket shaft, thereby driving the sprocket mounted on the sprocket shaft, and then driving the steps, comb plates and handrails. At present, when an abnormal situation occurs in the general elevator, the motor is braked only by cutting off the power supply of the motor. The braking measure is relatively simple, and the elevator may go backwards, and the safety of passengers cannot be guaranteed. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a safety bra...
