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.

Abstract

Disclosed is an elevator fall-prevention mechanism with a compound locking sliding block. The elevator fall-prevention mechanism comprises a crank, a connection rod, the locking sliding block, a control rod and stop blocks. The locking sliding block is arranged on a lift car frame and can slide horizontally. One end of the connection rod is connected with the locking sliding block, and the connection rod can swing with the corresponding connection point as the pivot. The other end of the connection rod and one end of the crank are connected and can swing mutually with the corresponding connection point as the pivot. The other end of the crank is connected with the lift car frame, and the crank can swing with the corresponding connection point as the pivot. One end of the control rod and the crank are connected and can swing mutually with the corresponding connection point as the pivot. The other end of the control rod is arranged in a lift car. The stop blocks are arranged on a well wall. Floating plates are arranged on the upper surfaces of the stop blocks and connected with the stop blocks through a set of springs. The locking sliding block comprises a metal layer and an annular high-manganese steel wire mesh arranged in the metal layer. When an existing fall-prevention device loses efficacy, people in an elevator can brake the elevator manually, and thus self rescue of the personnel in the elevator is achieved.

Description

technical field [0001] The invention relates to an anti-falling device, in particular to an elevator anti-falling mechanism with a composite locking slider. 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 buffe...
