Abstract

The invention discloses an elevator anti-falling centrifugal ball device. The device comprises anti-falling gears, wherein the anti-falling gears are installed on the side, away from a heavy object, of an elevator car, and the plurality of anti-falling gears are arranged on the elevator car; a tooth wall is arranged on the outer side of the elevator car, wherein teeth on the tooth wall mesh with the anti-falling gears, fixing frames are arranged on the two sides of the axis of each anti-falling gear, and a locking sliding rail is arranged on each fixing frame; a locking support is installed in each locking sliding rail, locking teeth are arranged at the top of each locking support, a spring is installed at the bottom of each locking support, one end of each spring is installed at the bottom of the corresponding locking support, and a sensitive ball is arranged at the other end of the corresponding spring. Compared with the prior art, the elevator anti-falling centrifugal ball device has the advantages that the sensitive balls are moved out of the bottom of the locking supports through weightlessness, the locking supports integrally fall down under the action of gravity so that the anti-falling gears can be fixed, the elevator car is prevented from continuously falling, and thus safety is achieved. The whole device is simple in structure, low in cost and quite convenient to install, and therefore has good market prospects.

Description

technical field [0001] The invention relates to the field of elevator safety accessories, in particular to an elevator anti-drop centrifugal ball 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 that are perpendicular to the horizontal plane or at an inclination angle of less than 15° from the plumb line. There is also a step type, and the tread plate is installed on the crawler belt to run continuously, commonly known as an escalator or a moving walk. Fixed lifting equipment serving specified floors. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in buildings regard...
