Elevator car fall protection safety device

Abstract

The invention discloses a falling protection safety device of an elevator car. The falling protection safety device comprises the elevator car and cavities formed in the side portions of all layers of an elevator shaft. The cavities are located in the upper portions of the stopping positions of the elevator car. Each cavity is internally provided with vertical rotating shafts and guiding sleeves. Each rotating shaft is provided with a rotating rod, the middle portions of the rotating rods are hinged to the rotating shafts, the two ends of each rotating rod are hinged to one end of a first universal coupling and one end of a second universal coupling correspondingly, the other end of each first universal coupling is hinged and connected to the side edge of an elevator landing door, an inserting rod is hinged to the other end of each second universal coupling, and each inserting rod is matched with the corresponding guiding sleeve. After the elevator car reaches a corresponding floor and the corresponding elevator landing door is opened, the corresponding elevator landing door is moved towards the two sides and pushes the corresponding rotating rods to rotate around the corresponding rotating shafts, the corresponding inserting rods move towards the elevator shaft and can be inserted in inserting pipes, so that suspension supporting is added for the top of the elevator car, even the falling situation happens, safety is effectively improved due to the action of the inserting rods and the inserting pipes, and sufficient protection can be provided the moment the falling accident happens.

Description

technical field [0001] The invention belongs to the field of elevator engineering, in particular to a safety device for protecting an elevator car from falling. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, which is used for multi-storey buildings to take people or carry goods. With the continuous construction of high-rise buildings, elevators are widely used as vertical transportation tools in buildings. The use of the elevator also brings a greater safety risk. When the elevator door is opened, the elevator car only has a suspension force point, lacking supporting protection, and once a fall occurs, it will cause a very large danger. Contents of the invention [0003] The invention provides an elevator car fall protection safety device to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] The elevator car ...
