Vertical lift capable of achieving manual falling prevention

Abstract

The invention discloses a vertical lift capable of achieving manual falling prevention. The vertical lift comprises a lift car, a shaft well, a lift car frame, a locking device, a joystick and stop dogs, wherein the locking device is arranged on the lift car frame and can move axially; one end of the joystick is arranged on the lift car frame and matched with the locking device in shape, the other end of the joystick is arranged in the lift car, and the joystick can move axially; and the stop dogs are arranged on the shaft wall and matched with the locking device in shape. When an existing anti-falling device fails, a person in the lift can manually brake the lift to achieve the purpose of falling prevention, and self rescue of the person in the lift is achieved.

Description

technical field [0001] The invention relates to a vertical elevator, in particular to a vertical elevator capable of manually preventing falling. Background technique [0002] In recent years, with the advancement of urbanization and the improvement of residents' living standards, elevators have become an indispensable means of vertical transportation in people's production and life. In order to ensure safe operation, general vertical elevators are equipped with anti-falling devices. Gear, safety gear and the buffer at the bottom of the hoistway and other devices to achieve. Once it is found that the elevator is descending at an overspeed, the speed limiter will first stop the elevator driving the main engine. If the inside directly hits the buffer, the car will also stop. However, an error in any part of the system or failure of components may lead to the paralysis of the entire anti-fall system. When the car lands at an extremely fast speed, although the buffer can reduc...

Problems solved by technology

However, an error in any part of the system or failure of components may lead to the paralysis of the entire anti-fall system. force, but the effect is limited, and it may still cause casualties to the occupants in the elevator

Although the vertical elevator has been equipped with the above two anti-fall protection devices, it still cannot completely avoid the occurrence of elevator falling accidents.
