Abstract
The disconnected rope safety guard of high rise elevator; there are pulley and steel wire rope thereon at the top of cab, cab upper beam center has a steel shaft worn under axis hole, pulley to wear axis hole; it is fixed on lower clamp, lower clamp is connected and tensed with the brake apparatus that the disconnected rope in cab starts.When elevator is normally run, steel wire rope tenses coupling rod by lower clamp, suspending rod, and actuating strut is pulled in safe rod set by eccentric rod；When elevator wire rope disconnects, end loses the pulling force to lower clamp, suspending rod and coupling rod, spring spring armed lever upper end is moved downward, disk is driven to rotate clockwise, eccentric rod releases actuating strut outside safe rod set, after actuating strut stretches out, cab falls to being no more than a floor, and the end of actuating strut will decline, finally be shelved on safety board.The present invention, which makes full use of, to be resolved after rope, and the steel wire rope of lifting loses pulling force, and lever-type safety guard is started immediately, is made less than one floor of used during elevator falling, is improved the reliability of elevator safety.
Description
Technical field
The present invention relates to elevator, a kind of particularly disconnected rope safety guard of high rise elevator.
Background technology
In the prior art, when disconnected rope situation occurs in elevator wire rope, the elevator safety friction of elevator brake car is passed through
Car, can be clamped on the slide rail of elevator both sides by pincers, but be due to that lift car weight is big, highly big, safe friction clamp
Sometimes pincers are not lived, and the accident of used during elevator falling occurs for occasional, people is felt worried.
The content of the invention
Car is by the safeguard protection dress of stop immediately if it is an object of the invention to provide disconnected rope occur once elevator wire rope
Put.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
Have at the top of the disconnected rope safety guard of this high rise elevator, including the cab for passenger, cab pulley and
Steel wire rope thereon, it is characterised in that cab upper beam center has a steel shaft worn under axis hole, pulley to wear axis hole, it is fixed
On lower clamp, lower clamp is connected and tensed with the brake apparatus that the disconnected rope in cab starts.
When elevator is normally run, steel wire rope drives cab to move up and down by pulley, steel shaft, lower clamp, once steel wire
Fracture of rope, brake apparatus is connected relaxation with lower clamp and started immediately, by cab stop.
The structure of brake apparatus is：On lower clamp, connected by the upper end of pin, hole and suspending rod, the lower end of suspending rod
Connected by the upper end of pin, hole and coupling rod, the lower end of coupling rod and the rotating shaft of disk are fixed together, the activity of rotating shaft two ends
In cab, disk is provided with eccentric rod at symmetrical 2 points by pin, hole, and eccentric rod passes through the dynamic of pin, hole and level
Make have safe rod set outside bar connection, actuating strut, safe rod set is fixed in cab, and spring arm is further fixed in the rotating shaft of disk
Bar, the upper end of spring armed lever is provided with spring, and the lower end of spring is fixed on cab wallboard, end and the safety board phase of actuating strut
Coordinate, safety board is fixed on relevant position of the elevator borehole wall of lift car walking per floor, when actuating strut stretches out, action
The ends rest of bar is on safety board.
When elevator is normally run, steel wire rope tenses coupling rod by lower clamp, suspending rod, and actuating strut is pulled in by eccentric rod
In safe rod set；When elevator wire rope disconnects, end loses the pulling force to lower clamp, suspending rod and coupling rod, and spring makes
Spring armed lever upper end is moved upwards, drives disk to rotate clockwise, eccentric rod releases actuating strut outside safe rod set, works as action
After bar stretches out, cab falls to being no more than a floor, and the end of actuating strut will decline, finally be shelved on safety board.
The present invention is simple in construction, and reliability is high, makes full use of and resolves after rope, the steel wire rope of lifting loses pulling force, brakes
Device is connected relaxation with lower clamp, and lever-type safety guard is started immediately, makes less than one floor of used during elevator falling, carries
The high reliability of elevator safety.
