An 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, including 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, the passenger protection mechanism and the elevator indication mechanism The mechanisms are all set on the elevator protection mechanism. There are two chutes on the left and right sides of the top surface of the elevator body. The side of the chute close to the center of the elevator body is fixedly connected with a spring A. Through the setting of the elevator protection mechanism, according to the rotation speed of the elevator To automatically judge the safety of the elevator, when the elevator falls, it can automatically and quickly start the operation of the elevator protection mechanism, use the two stickers to closely fit the walls on both sides of the elevator, and use friction to slow down the elevator's falling speed , prevent the elevator from falling to the ground at high speed and cause harm to passengers, and use the thrust on both sides to make the elevator straighten, avoiding the problem that the elevator shakes and the passengers are bumped.

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
