An elevator emergency braking device

Abstract

The invention relates to the field of emergency braking devices of elevators, in particular to an emergency braking device of a lifting elevator. The emergency braking device comprises guide structures, limiting structures, an elevator body, lubricating structures, driving structures, a cleaning structure and anti-skid structures; the four guide structures are arranged on the four corners of the elevator body, the guide structures and the limiting structures are in sliding connection, so that the contact areas between the guide structures and the limiting structures are increased, the guide structures and the limiting structures are more stable in sliding, then the elevator body is more stable in the lifting process, and the dislocation of the guide structures and the limiting structures caused by uneven placement of construction articles on the elevator body is effectively avoided; the anti-skid structures for limiting guide structures and limit structures are arranged in the guide structures, and the driving structures are arranged in the guide structures; when the sliding speed between the guide structures and the limiting structures is abnormal, the guide structures control thedriving structures to drive the anti-skid structures to brake the guide structures, so that the lifting elevator is braked emergently.

Description

technical field [0001] The invention relates to the field of elevator emergency braking devices, in particular to an elevator emergency braking device. Background technique [0002] Elevator refers to the permanent transportation equipment that serves several specific floors in the building, and its car runs on at least two rigid rails perpendicular to the horizontal plane or with an inclination angle of less than 15° from the plumb line. Running continuously on the crawler belt, commonly known as escalators or moving walks, serving fixed lifting equipment for specified floors, vertical lifts have a car that runs between at least two vertical or rigid guide rails with an inclination angle of less than 15°, For example, in the elevator used in building construction, the elevator body is pulled by the elevator wire rope to move vertically. [0003] However, when the elevator is used in a construction site, due to the high-altitude operation, and the center of gravity of the g...

AI Technical Summary

Problems solved by technology

[0003] However, when the elevator is used in a construction site, due to the high-altitude operation, and the center of gravity of the goods placed on the elevator is not at the center of the elevator body, it is easy to cause the elevator and the guide rail to deviate, thereby affecting the conveying quality. It is not convenient to apply lubricating oil to the guide rails of the elevator, and the gravitational potential energy cannot be used during the elevator's downward process. When the steel wire rope breaks, the elevator body is not convenient for emergency braking according to the running speed of the elevator. At the same time, it is easy to break the power cord, causing safety ACCIDENT
