A kind of upward overspeed protection device for elevator

Abstract

The invention belongs to the technical field of low-floor elevator protection, and discloses an elevator overspeed protection device, which comprises a car frame, auxiliary frames placed on both sides of the car frame, a speed limiter box fixed on the back of the car frame, and a The speed detector above the car frame, the speed limiter box has a built-in iron core with externally wound conductive windings, an adsorption piece placed under the iron core, and a fixed guide plate symmetrically arranged on both sides of the adsorption piece. The guide rod of the speed limiter box and the elastic piece wound around the guide rod body, one end of the guide rod is connected with a traction rope wound around the bottom of the adsorption piece, and one end of the guide rod facing the auxiliary frame is provided with a guide wheel; When the speed of the floor elevator is too fast during the upward process, energize the iron core with the external conductive winding to attract the suction part, and push the traction rope wound around the bottom of the suction part through the fixed guide plate to move vertically downward until it is separated from the suction part, and then The guide wheel is ejected from the elastic piece to the auxiliary frame to increase the resistance, so as to realize the elevator deceleration.

Description

technical field

[0001] The invention belongs to the technical field of protection of low-floor elevators, and in particular relates to an upward overspeed protection device for elevators. Background technique

[0002] With the development of society, the use of elevators has become more and more common. It has been used only in commercial buildings and hotels, and has been used in office buildings, residential buildings and other places. Vertical elevators are the most common. Popularity has brought convenience to people's lives, but the accompanying elevator accidents have gradually increased, and people have begun to pay more and more attention to the safety protection measures of vertical elevators. Elevators generally include four major spaces and eight systems. The four major spaces include the machine room part, the shaft and the pit part, the car part and the landing part. The eight major systems generally include the traction system, the guidance system, the car syst...
