Abstract
The invention discloses a rope break anti-fall device. The rope break anti-fall device comprises a cage, tracks, a movable pulley, fixed pulleys, anti-fall supports, anti-fall device bodies and a rack. The cage is movably connected with the tracks, and the anti-fall supports are arranged between the tracks on the two sides of the cage. A steel wire rope is arranged in the movable pulley and used for lifting the cage. The fixed pulleys, the rack and the anti-fall device bodies are arranged at the top end of the cage, steel wire ropes are arranged in the fixed pulleys, one end of each steel wire rope is connected with the movable pulley, and the other end of each steel wire rope is connected with the corresponding anti-fall device body on the rack. The anti-fall device bodies are movably connected with the rack, and when the anti-fall device bodies move forwards, the front ends of the anti-fall device bodies can stretch into the anti-fall supports. The rope break anti-fall device is simple in structure, high in safety index due to the full-mechanical structure, easy to construct and low in cost.
Description
Technical field
The present invention relates to a kind of disconnected rope anti-fall device, belong to Electric Hoist device technique field.
Background technology
At present, the Electric Hoist of use is adopted almost without falling proof device, the falling proof device of existing elevator more
With holding track tightly, or auxiliary security steel wire rope works.But this falling proof device is the most complicated for Electric Hoist,
It is unfavorable for in-site installation and realization.
Summary of the invention
Purpose: in order to overcome the deficiencies in the prior art, the present invention provides a kind of disconnected rope anti-fall device.
Technical scheme: for solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of disconnected rope anti-fall device, including: cage, track, movable pulley, fixed pulley, Anti-dropping rack, anti-fall device, frame, described
Cage and track mobile link, described cage both sides interorbital is provided with Anti-dropping rack；It is provided with steel wire in described movable pulley
Rope, for elevator cage；Cage top is provided with fixed pulley, frame, anti-fall device, is provided with steel wire rope in described fixed pulley,
Steel wire rope one end is connected with movable pulley, and the other end is connected with the anti-fall device in frame；Described anti-fall device moves with frame
Being dynamically connected, when anti-fall device moves forward, front end can be stretched in Anti-dropping rack.
Described anti-fall device includes that steady pin, spring, described steady pin rear end are connected with steel wire rope, and steady pin is in frame
Interior mobile link, steady pin rear end is provided with spring, quickly ejects frame for steady pin.
Described Anti-dropping rack is provided with multiple tabula part.
Preferably, described fixed pulley, Anti-dropping rack, anti-fall device, the quantity of frame are set to two.
Preferably, described steel wire rope uses double twist composite steel rope.
Preferably, described spring uses alloy spring steel material.
Beneficial effect: the one that the present invention provides disconnected rope anti-fall device, when wire cable rupture, steel wire rope pulling force upwards
Disappearing, movable pulley falls, the looseness of steel wire ropes being connected with movable pulley, the spring effect that steel wire rope is compressed in anti-fall device
Under, steady pin ejects along frame, on the tabula part of the steady pin of ejection to Anti-dropping rack, stops cage to fall.The design structure
Simply, full mechanical, safety index is high, easily constructs, low cost.
