Abstract
The invention relates to a high rise elevator rope-breaking safety protection device. A pulley and a steel wire rope on the pulley are arranged on the top part of an elevator compartment; a shaft penetrating hole is formed in the center of an upper beam of the elevator compartment; a steel shaft under the pulley penetrates through the shaft penetrating hole so as to be fixed on a lower clamping plate; the lower clamping plate is connected with a braking device for starting a breaking rope on the elevator compartment and tenses the braking device. When an elevator operates normally, the steel wire rope tenses a shaft connecting rod through the lower clamping plate and a hanger rod, and an eccentric rod tenses an actuator rod in a safety rod sleeve; when the elevator steel wire rope is broken, the rope end loses the tensile force on the lower clamping late, the hanger rod and the shaft connecting rod, the upper end of a spring arm lever moves downwards to drive a disk to rotate clockwise, the eccentric rod pushes the actuator rod out of the safety rod sleeve, after the actuator rod stretches out, the elevator compartment is dropped less than one floor, and the end part of the actuator rod can be dropped and finally laid on a safety board. According to the safety protection device provided by the invention, after the rope is broken, the hoisted steel wire rope loses the tensile force, and the lever type safety protection device is started immediately, so that the elevator can be dropped less than one floor, and the reliability of the elevator safety is improved.
Description
Technical field
The present invention relates to elevator, particularly a kind of high rise elevator disconnected rope safety guard.
Background technology
In prior art, when there is disconnected rope situation in elevator wire rope, by the elevator safety friction clamp of elevator brake car, car can be clamped on the slide rail of elevator both sides, but due to lift car weight greatly, highly big, safe friction clamp clamps incessantly sometimes, and the accident of occasional generation used during elevator falling still makes people feel worried.
Summary of the invention
It is an object of the invention to provide once disconnected rope occurs in elevator wire rope, car is by the safety guard of stop immediately.
For reaching above-mentioned purpose, the technical solution used in the present invention is:
This high rise elevator disconnected rope safety guard; including the cab for passenger; pulley and steel wire rope thereon are arranged at cab top; it is characterized in that; cab upper beam center has one to wear axis hole; steel axle under pulley wears axis hole, is fixed on lower clamp, and the brake unit that lower clamp starts with the disconnected rope in cab is connected and strains.
When elevator is properly functioning, steel wire rope drives cab to move up and down by pulley, steel axle, lower clamp, once wire cable rupture, brake unit is connected with lower clamp lax and starts immediately, by cab stop.
The structure of brake unit is: on lower clamp, by pin, hole is connected with the upper end of suspending rod, pin is passed through in the lower end of suspending rod, hole is connected with the upper end of coupling rod, the lower end of coupling rod and the rotating shaft of disk are fixed together, what rotating shaft two ends were movable is arranged in cab, disk is at 2 symmetrical points, by pin, hole is provided with eccentric rod, eccentric rod passes through pin, hole is connected with the actuating strut of level, safety pole set is had outside actuating strut, safety pole set is fixed in cab, the rotating shaft of disk is further fixed on spring armed lever, the upper end of spring armed lever is provided with spring, the lower end of spring is fixed on cab wallboard, the end of actuating strut matches with safety board, safety board is fixed on the relevant position of the every floor of the elevator borehole wall of lift car walking, when actuating strut stretches out, the ends rest of actuating strut is on safety board.
When elevator is properly functioning, steel wire rope is by lower clamp, suspending rod tension coupling rod, and actuating strut is pulled in safety pole set by eccentric rod；When elevator wire rope disconnects, end loses the pulling force to lower clamp, suspending rod and coupling rod, spring makes spring armed lever upper end move upward, disk is driven to rotate clockwise, actuating strut is released outside safety pole set by eccentric rod, after actuating strut stretches out, cab falls less than a floor, and the end of actuating strut will decline, finally be shelved on safety board.
Present configuration is simple, and reliability is high, makes full use of after resolving rope; the steel wire rope of lifting loses pulling force, and brake unit is connected lax with lower clamp, starts lever-type safety guard immediately; make used during elevator falling less than a floor, improve the reliability of elevator safety.
