Safety linkage device for people and goods elevators in building construction

Abstract

The invention discloses a building construction people-cargo elevator safety linkage device and belongs to the field of elevator safety. According to the key points in the technical scheme, the devicecomprises an elevator well and a car in sliding connection with the interior of the elevator well, a safety protection system is arranged on the car, multiple sets of linkage protection devices are arranged in the elevator well in sequence from top to bottom, each set of linkage protection device comprises multiple supporting plates, the supporting plates can stretch out of the elevator well, thesupporting plates are in abutting connection with the bottom of the car when stretching out and support the car, the upper surfaces of the supporting plates are provided with arc faces, and the arc faces are extended upwards from the ends, close to the car, of the supporting plates to the other ends, the linkage protection device further comprises a recycling device which can recycling the supporting plates into the elevator well in sequence from top to bottom , the problem that staff in the car is difficult to rescue when an elevator is powered off and the car is clamped between two floors is solved, and the effect that the car can slowly fall down to the position of an elevator entrance when the elevator is powered off, and therefore workers can get away from the elevator from the elevator entrance is achieved.

Description

technical field [0001] The invention relates to the field of elevator safety, in particular to a safety linkage device for building construction personnel and freight elevators. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. Once the elevator fails, usually its own traction system fails, and the elevator car will get stuck in the deep shaft of the elevator or fall directly. The general elevator itself has a safety protection system. The safety protection system can start when the elevator breaks down and brake the elevator in an emergency to prevent the elevator from falling, so as to protect the safety of the people in the car. [0003] For the prior art, please refer to the Chinese patent whose authorized announcement number ...
