Elevator with multiple safety protection functions

Abstract

The invention relates to the technical field of elevators, and discloses an elevator with multiple safety protection functions. The elevator comprises an elevator body, an elevator protection mechanism, a passenger protection mechanism and an elevator indication mechanism. The elevator protection mechanism is arranged on the elevator body, and the passenger protection mechanism and the elevator indication mechanism are both arranged on the elevator protection mechanism. The left side and the right side of the top face of the elevator body are each provided with two sliding grooves, and the surfaces, close to the center of the elevator body, of the sliding grooves are fixedly connected with springs A. By arranging the elevator protection mechanism, the safety of the elevator can be automatically judged according to the rotating speed of the elevator, and when the elevator falls, the elevator protection mechanism can be automatically and rapidly started to operate. Two attaching plates are used for being tightly attached to the walls on the two sides of the elevator, the falling speed of the elevator is reduced through friction force, the elevator is prevented from falling to the ground at a high speed to cause harm to passengers, the elevator is straightened through thrust on the two sides, and the problem that the passengers are collided due to shaking of the elevator is avoided.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator with multiple safety protection functions. Background technique [0002] During the use of elevators, various situations may occur in elevators due to power outages and other problems. Among them, the most harmful thing to passenger safety is the elevator falling. At the moment when elevators are very popular, avoiding such situations has become an urgent problem. [0003] The existing patent No. CN105236231B proposes an elevator protection mechanism. Once the elevator accidentally rises or falls, the travel switch will control the elevator power to be disconnected in time, and the car will be supported by the crank arm, so as to reduce accidents. However, when problems such as cable breakage and pulley block fall off occur, the effect of the device controlling the elevator through the travel switch is zero, and the effect of reducing the risk of elevator falling is...

Problems solved by technology

[0003] The existing patent No. CN105236231B proposes an elevator protection mechanism. Once the elevator accidentally rises or falls, the travel switch will control the elevator power to be disconnected in time, and the car will be supported by the crank arm, so as to reduce accidents. However, when problems such as cable breakage and sheave block fall-off occur, the effect of the device controlling the elevator through the travel switch is zero, and the effect of reducing the risk of elevator falling is too low

[0004] The existing patent number CN105366461B proposes a protective device for the accompanying cable of an elevator, which can avoid the risk of the accompanying cable being broken during the operation of the elevator, and at the same time improve the service life of the accompanying cable and ensure the smooth operation of the elevator, but its effect is on the On the cables, even if the cables and steel cables are protected, the elevator has the risk of falling due to other reasons, so the protection effect of the device on the passengers in the elevator is still low, and the protection of the elevator is actually the protection of the safety of the passengers. The device does not provide adequate protection for occupants
