Abstract

The invention belongs to the field of wireless elevators and particularly relates to a direct-driving elevator anti-falling safety device which comprises a fixing support assembly arranged along a shaftway and safety tongs for clamping a braking track. The direct-driving elevator anti-falling safety device is characterized in that a pulling steel wire rope for triggering the safety tongs is fixedly wound on a rope sheave; the rope sheave is connected to one end of an overrun clutch through a connecting shaft I; the other end of the overrun clutch is connected with a gear connecting shaft II; bearings on the connecting shaft I and the connecting shaft II are fixed on bearing bases; the bearing bases are fixed on a mover for bearing a lift car or a speed measuring and speed limiting lifting mechanism fixing plate of a lift car frame; a rack meshed with a gear is fixed on at least one side face of the fixing support assembly. The safety tongs are arranged on the braking track; the rope sheave connected with the triggering lifting steel wire rope is connected with the overrun clutch which is connected with the gear capable of measuring the speed of the lift car; accordingly, quick braking can be achieved; safety and reliability are achieved.

Description

technical field [0001] The invention belongs to the field of cordless elevators, and in particular relates to a safety device for preventing falling of a direct drive elevator. Background technique [0002] Elevators are an important transportation link in various buildings. Linear motor cordless hoists that do not require wire ropes and a separate mechanical room have been proposed for a long time. In the prior art, there are direct-drive elevators for high-rise buildings and mines, and there are cost and reliability issues. more or less question. In the prior art, the patent "Direct Drive Home Elevator" (Patent No.: CN201010528066.X) proposes a safety speed limit protection device: it is composed of a gear, a rack, a ball throwing mechanism, a swing rod mechanism, and a torsion spring. The mechanism is coaxially connected with the gear, and is also connected with the pendulum mechanism. The gear runs along the rack at the same speed as the car. The gear drives the coaxial...
