Vertical elevator with high-strength locking pin

Abstract

Disclosed is a vertical elevator with a high-strength locking pin. The vertical elevator comprises a lift car, a well wall, a lift car frame, a locking device, a control rod and stop blocks. The locking device is arranged on the lift car frame and can move axially. One end of the control rod is arranged on the lift car frame and matched with the locking device in shape. The other end of the control rod is arranged in the lift car, and the control rod can move axially. The stop blocks are arranged on the well wall and matched with the locking device in shape. The locking device comprises a first elastic part and the locking pin. One end of the first elastic part and the locking pin are connected mutually. The other end of the first elastic part and the lift car frame are connected mutually. The locking pin comprises a set of long fibers and a metal layer. The set of long fibers are evenly distributed in the metal layer and formed in a squeeze casting mode. The direction of the long fibers is parallel to the axial direction of the locking pin. A buffer layer is arranged on the periphery of the locking pin. When an existing fall-prevention device loses efficacy, people in the elevator can brake the elevator manually to achieve the fall-prevention purpose, and thus self rescue of the personnel in the elevator is achieved.

Description

technical field [0001] The invention relates to a vertical elevator, in particular to a vertical elevator with high-strength locking pins. 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 reduce the i...

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.
