Vertical lifting elevator with fall protective function

Abstract

The invention discloses a vertical lifting elevator with the fall protection function. The vertical lifting elevator comprises outer frames fixed to lift cars, wherein tooth rows extending in the vertical direction are formed on the two sides of the outer frames, and protective plates located between elevator doors and the lift cars are arranged at the middle position of the elevator doors in a matched mode in the horizontal direction; guide wheels, rope winding wheels and connecting ropes are correspondingly arranged on the two sides of the elevator doors in a matched mode in the vertical direction; the rope winding wheels are arranged at the middle position of the elevator doors in the vertical direction, the rope winding wheels sleeve gears which can mesh with the tooth rows, and the guide wheels are arranged above the elevator doors; the protective plates include lifting portions and telescopic portions, the telescopic portions are telescopically connected under the lifting portions, the lifting portions are fixedly connected to one ends of the connecting ropes, and the other ends of the connecting ropes bypass the guiding wheel and are fixedly connected with the rope winding wheels; and when the lift cars are lifted or lowered, the rope winding wheels pull the connecting ropes to lift the protective plates, and when the tooth rows are separated from the gears, the protective plates are lowered downwards under the effect of gravity to block the elevator doors. According to the structure of the vertical lifting elevator, falling accidents can be effectively prevented.

Description

technical field [0001] The invention relates to the field of elevator safety protection, in particular to a helicopter elevator with a fall protection function. Background technique [0002] Helicopters are widely used in many places such as shopping malls, residential buildings, hospitals and entertainment. They usually include a car, a vertical track and a motor. The car can be lifted up and down along the vertical track driven by the motor. sports. [0003] During the operation of the above-mentioned elevator, since the car reciprocates up and down on the vertical track, when the car is at a higher position, the space below the car usually does not have any barriers. Once the elevator door on the lower floor is opened or maliciously pried open, and someone directly enters the elevator without attracting attention, there is a risk of falling directly from a high place, which brings great safety hazards to people. [0004] In view of this, the applicant conducted in-depth...
