The invention relates to a safety protection device for accidental movement of an elevator car. The safety protection device comprises a transition support and a support component. The support component is slidably connected with the transition support, transmission shafts are arranged on the support component, cams are arranged at the front ends of the transmission shafts, transmission gears mutually meshed are arranged at the rear ends of the transmission shafts, driving gears meshed with the transmission gears are connected with driving motors, a self-locking wheel capable of vertically moving and the cams are arranged on the left and the right of guide rails respectively, the cams are driven to rotate by gear transmission belts, and the guide rails are finally clamped by matching of the cams and the self-locking wheel. The safety protection device for accidental movement of the elevator car is small in size, quick to act, good in self-locking performance, bidirectional in brake, safe, reliable and convenient to manufacture and is low in use cost.
Description
technical field [0001] The present invention relates to the technical field of application of detection, fault correction or safety devices in elevators, in particular to a device that uses friction between a car, a cage or a skip and a fixed guide element or a hoisting channel or the inner surface of an elevator shaft. A brake or pawl device for braking force. Background technique [0002] When the elevator is in the state of opening the door after leveling, during the normal process of people entering and exiting or loading and unloading goods, due to a failure of an electrical component of the elevator or a component of the traction braking system, the car accidentally moves away from the landing , so that there are serious accident hazards in the elevator, so it is urgent to increase the corresponding safety protection device to prevent the car from moving accidentally. Contents of the invention [0003] The technical problem to be solved by the present invention is t...
