The invention discloses an elevator overspeed protection device. The elevator overspeed protection device comprises electromagnetic safety tongs and a speed detection mechanism, wherein the electromagnetic safety tongs are installed on an elevator car and comprise electromagnets and clamp bodies driven by the electromagnets, the clamp bodies are connected to guide rails in a clamped mode and have an opening state and a closing state, and when the electromagnets are powered on and powered off, the clamp bodies can be converted between the opening state and the closing state; the speed detection mechanism is installed on the elevator car, is used for detecting a speed of the elevator car, and is electrically connected with the electromagnets to control the electromagnets to be powered on and powered off; and when the speed detection mechanism detects that the elevator car is overspeed, an overspeed signal is sent to an elevator control system to stop output, and the electromagnets are powered off to convert the clamp bodies into the closing state, so that the guide rails are clamped to stop the elevator car. According to the invention, speed-limiting overspeed protection is achieved, the trigger protection response speed is high, a structure is simple, the material cost can be saved, an installation process is simplified, and installation time is shortened.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator overspeed protection device which simplifies the installation process and saves material costs. Background technique [0002] At present, the overspeed protection of the elevator speed limiter uses a mechanical speed limit scheme. The elevator speed limiter is composed of a speed limiter, a wire rope, a clamp and a tensioning wheel. The speed limiter is installed in the machine room, the clamp is installed in the car, and the tensioning wheel is installed in the pit. The speed limiter, clamp and tensioning wheel are connected together by a wire rope. The clamp realizes the brake, so that the elevator is forcibly stopped on the guide rail. [0003] The cost of the existing elevator speed limiter is high, the installation process and process are cumbersome, the installation time is long, and the response speed of the mechanical speed limiter is slow, which is not con...
