Abstract

The invention discloses a safety car device for an elevator, and relates to the technical field of elevator safety. The problem that passengers cannot save themselves under the condition that safety tongs of an elevator car are locked in the prior art is solved. The device is technically characterized in that the safety car device comprises a car body and a safety unit, and the safety unit comprises clamping plate units, wherein the clamping plate units are used for braking the elevator; a clamping plate driving unit used for driving the clamping plate units to be close to or away from each other; a main driving unit used for recognizing the stall state of the elevator and controlling the clamping plate units to be close to or away from each other through the clamping plate driving unit; and a manual control unit used for manually controlling the clamping plate driving unit. The clamping force of the clamping plate units on guide rails can be controlled to be gradually reduced throughthe manual control unit so that the elevator can slowly descend to an elevator opening, and the passengers can prize up an elevator door for self rescue.

Description

technical field [0001] The invention relates to the technical field of elevator safety, in particular to a safety car device for an elevator. Background technique [0002] With the progress of urbanization, more and more people live in high-rise buildings. Elevators are necessary transportation equipment for high floors, and are used to transport people or goods to preset floors. [0003] Elevator safety gear is a safety device that stops the car in an emergency and clamps it on the guide rail when the elevator has a very serious fault such as overspeed or broken rope under the control of the speed limiter. It provides a guarantee for the safe operation of the elevator. Effective protection. [0004] After the safety gear in the prior art clamps the elevator guide rail under the control of the speed governor, the elevator will stay at a certain position in the elevator shaft. For a long time, passengers in the elevator cannot save themselves during this period, which cause...
