[0003] This kind of brake needs to hold the brake wheel tightly for a long time due to the working principle. At the same time, most of the existing elevators use intelligent control of the long-term braking and operation of the elevator. It is not practical to use the brake to realize it. The function of the brake has been replaced by other intelligent preparations. Instead, the existing smart elevators have abandoned the role of the existing brakes, and only need to give timely braking when the elevator falls rapidly

Embodiment Construction
[0009] The present invention will be described in further detail below in conjunction with the embodiments in the accompanying drawings, but this does not constitute any limitation to the present invention.
[0010] see figure 2 As shown, there are eight major systems in the elevator, and the relationship between each system has been clarified and normalized. The elevator traction system and electrical and electrical control system are used in this new realization; the elevator traction system includes traction motor 1, brake 2, Speed reducer 3, traction sheave 4, traction rope 5, guide wheel 6, car 7 and counterweight 8; Said speed reducer 3 is arranged between traction motor 1 and traction sheave 4, is used to increase the Dynamic torque; the brake 2 is arranged between the traction motor 1 and the reducer 3 for braking; the traction sheave 4, the traction rope 5, the guide wheel 6, the car 7 and the counterweight 8 form a conventional elevator The necessary traction str...

The invention discloses an anti-falling device for an elevator. The anti-falling device for the elevator comprises a brake. The brake comprises a brake electromagnet which is connected with an elevator electric control system and composed of an electromagnet core. Brake arms are connected to the two sides of the brake electromagnet. A space for limiting a brake wheel is defined by the two brake arms. The brake wheel is integrally hollow and is divided into an inner brake wheel body and an outer brake wheel body. A traction motor rotary shaft is fixedly connected into the inner brake wheel body. The outer brake wheel body is fixedly connected with a brake lining. The inner brake wheel body and the outer brake wheel body are integrated through a connecting shaft. A plurality of sets of ballssliding on the inner side of the outer brake wheel body are arranged in the gap between the inner brake wheel body and the outer brake wheel body. A baffle is arranged at the position where the upperouter side of the outer brake wheel body is connected with a brake shoe. An infrared sensor is arranged at the topmost end of the baffle. According to the anti-falling device for the elevator, the centrifugation speed of the balls is associated with the falling speed of the elevator, and the elevator electric control system controls the brake electromagnet through the infrared sensor to achieve braking.
Description
technical field [0001] The invention relates to an elevator fall prevention device. Background technique [0002] The working principle of the existing brake: when the elevator is in a static state, there is no current passing through the coils of the traction motor and the electromagnetic brake. Hold the brake wheel tightly to ensure that the motor does not rotate; when the traction motor is energized and rotates, the coil in the brake electromagnet is simultaneously energized with current, and the electromagnet core is quickly magnetized and engaged, driving the brake arm to make the brake spring When the force is applied, the brake pads are opened and completely disengaged from the brake wheels, and the elevator can run; when the elevator car reaches the desired stop, the traction motor loses power, and the coil in the brake electromagnet also loses power at the same time , the magnetic force in the electromagnet core disappears quickly, and the iron core resets through ...
