Low-power-consumption elevator brake

Abstract

The low-power-consumption elevator brake belongs to the technical field of elevator brakes and comprises a device body and a collecting box located on the inner side of the device body, a base is installed at the bottom of the device body, a collecting groove is formed in one side of the base, and a dust suction pipe communicated with the collecting groove is communicated with the top of the device body in a penetrating mode. An intercepting module is arranged at the top end of the dust suction pipe, one side of the base communicates with an air outlet pipe communicating with the collecting tank, an exhaust fan is arranged in the air outlet pipe, and the base is provided with a filtering module through the collecting tank. According to the low-power-consumption elevator brake, dust attached to the device body and dust around the device body are sucked into the collecting groove through the dust suction pipe by periodically starting the air suction pump, and then the dust is intercepted through the filter screen, so that the effect of treating the dust is achieved, and it is helpful for preventing the dust from entering the device body; the heat dissipation performance of electronic components in the device is reduced, and the power consumption is increased.

Description

technical field [0001] The invention belongs to the technical field of elevator brakes, and in particular relates to a low-power consumption elevator brake. Background technique [0002] The elevator brake is an important safety device for the elevator. Its safety and reliability are one of the important factors to ensure the safe operation of the elevator. The two-way thrust elevator brake generates a two-way electromagnetic thrust when the power is turned on, so that the brake mechanism is separated from the rotating part of the motor. The force disappears, and under the action of the external brake spring pressure, a friction brake for power-off braking is formed. It is mainly matched with the drive motor on the escalator traction machine to form an electromagnetic brake three-phase asynchronous motor for escalators. It is widely used in It can realize smooth stop and fast start and safe braking in case of power failure. [0003] In the process of realizing the present i...
