The invention discloses a safety car device for an elevator, which relates to the technical field of elevator safety and solves the problem in the prior art that passengers cannot save themselves when the elevator car is locked by safety gear. The main body and the safety unit, the safety unit includes: a splint unit, the splint unit is used to brake the elevator; a splint drive unit, the splint drive unit is used to drive the splint units to approach or move away from each other; a main drive unit, the main drive The unit is used to identify the stall state of the elevator and the main drive unit controls the splint units to approach or move away from each other through the splint drive unit; the manual control unit is used to manually control the splint drive unit; the present invention can control the splint unit through the manual control unit The clamping force on the guide rail is gradually reduced, so that the elevator can slowly descend to the elevator entrance, so that passengers can pry open the 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...
