Abstract
The utility model discloses an elevator emergency braking apparatus including a casing, a brake head, an electromagnetic gravity type brake mechanism, a support rod, and a guide wheel. A tachymeter is arranged at the upper part of the casing, the support rod is arranged at the side of the casing, the guide wheel is arranged on the support rod, and the electromagnetic gravity type brake mechanism is arranged inside the casing. The elevator emergency braking apparatus can timely take an action when an elevator has a fault or falls down because of other reasons, and the braking apparatus can timely brake even when power failure occurs. Therefore, the braking apparatus provided is high in safety and reliability, and high in insurance coefficient.
Description
Technical field
The utility model relates to elevator field, relates in particular to a kind of elevator emergency brake gear.
Background technology
At present, China is high-rise and high-rise building is more and more, and elevator used is also more and more.The safety and reliability of elevator, is one of most important index, is related to personal safety.The various elevators that use at present, its safe reliability is not high, and conservative factor is inadequate, only has a kind of brake gear, and its brake is mainly arranged on traction or counterweight frame, generally adopts electronic band brake type, and once band-type brake breaks down, consequence is hardly imaginable.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of novel elevator emergency brake arrangement is provided.
The utility model is that following technical scheme is achieved: a kind of elevator emergency brake gear, comprises casing, brake head, electromagnetism gravity type boat davit braking mechanism, strut bar, track adjusting wheel, described casing top is provided with knotmeter, and casing sidepiece is provided with strut bar, and described strut bar is provided with track adjusting wheel, and described box house is equipped with electromagnetism gravity type boat davit braking mechanism, and described electromagnetism gravity type boat davit braking mechanism comprises permanent seat, sliding bar, brake head, Compress Spring, block, cliding seat, snake bend-type depression bar, extension spring, magnet coil, described permanent seat and cliding seat are all fixedly mounted on casing, in described permanent seat and cliding seat, be provided with sliding bar sliding back and forth, described sliding bar one end is installed with brake head, described Compress Spring is enclosed within on sliding bar, described Compress Spring one end withstands on permanent seat, the other end withstands on the block being fixedly mounted on sliding bar, described block contacts with snake bend-type depression bar, described snake bend-type depression bar is arranged in magnet coil, and become gap sliding type to be connected with magnet coil, on described snake bend-type depression bar, be set with extension spring.
The utility model principle of work is as follows: casing is arranged on lift car, the knotmeter on casing top is measured the running velocity of lift car, in the time that elevator speed is within allowed band, magnet coil is in charge condition, snake bend-type depression bar is produced to upwards thrust, make snake bend-type depression bar push down the block on sliding bar.The running velocity that measures lift car when knotmeter exceedes allowed band or elevator while accelerating due to fault, magnet coil power-off, snake bend-type depression bar is under the effect of gravity and extension spring, return downwards, block on sliding bar is released, sliding bar, under the effect of Compress Spring, drives brake head to stretch out compression guide rail, carries out emergency brake.
The utility model is provided with emergency brake arrangement on lift car, in the time that elevator electric band brake type produces fault or other reasons and causes elevator tenesmus, electromagnetism gravity type boat davit braking mechanism of the present utility model can move in time, even if in the time having a power failure, also can brake in time, realize the multiple safety protection of elevator, safe reliability is higher, conservative factor is larger, can effectively ensure elevator and contained personnel's safety, can have sufficient time maintenance and trouble-shooting.
Two pairs of track adjusting wheels are installed on casing of the present utility model, both can have ensured the steadily operation up and down of lift car, play directional tagging, can prevent from again toppling over of whole device from playing equilibrium activity.

In accompanying drawing, 1-casing, 2-permanent seat, 3-Compress Spring, 4-block, 5-knotmeter, 6-sliding bar, 7-strut bar, 8-track adjusting wheel, 9-cliding seat, 10-brake head, 11-snake bend-type depression bar, 12-extension spring, 13-magnet coil.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further elaborated.
A kind of elevator emergency brake gear, comprises casing 1, brake 10, electromagnetism gravity type boat davit braking mechanism, strut bar 7, track adjusting wheel 8.
Electromagnetism gravity type boat davit braking mechanism is equipped with in casing 1 inside, and electromagnetism gravity type boat davit braking mechanism comprises permanent seat 2, sliding bar 6, brake 10, Compress Spring 3, block 4, cliding seat 9, snake bend-type depression bar 11, extension spring 12, magnet coil 13.Permanent seat 2 and cliding seat 9 are all fixedly mounted on casing 1, are provided with sliding bar 6 sliding back and forth in permanent seat 2 and cliding seat 9.Described sliding bar 6 one end are installed with brake 10, and brake 10 is general adopts a wear-resisting powdered metallurgical material sintering to form.Compress Spring 3 is enclosed within on sliding bar 6, described Compress Spring 3 one end withstand on permanent seat 2, the other end withstands on the block 4 being fixedly mounted on sliding bar 6, described block 4 contacts with snake bend-type depression bar 11, described snake bend-type depression bar 11 is arranged in magnet coil 13, and be connected with 13 one-tenth gap sliding types of magnet coil, on snake bend-type depression bar 11, be set with extension spring 12.Snake bend-type depression bar 11 is made by magnetic material, and in the time that magnet coil 13 is filled with electric current, the magnetic field producing produces application force to snake bend-type depression bar 11, makes snake bend-type depression bar 11 compress the block 4 on sliding bar 6.When magnet coil 13 power-off, snake bend-type depression bar 11, under the effect of gravity and extension spring 12, is return downwards, and the block 4 on sliding bar 6 is released, and sliding bar 6, under the effect of Compress Spring 3, drives brake 10 to stretch out compression guide rail, carries out emergency brake.
Casing 1 top is provided with knotmeter 5, and the running velocity of lift car is measured.The running velocity that measures lift car when knotmeter 5 exceedes allowed band or elevator while accelerating due to fault, 13 power-off of control setup control magnet coil.Casing 1 sidepiece is provided with strut bar 7, and described strut bar 7 is provided with track adjusting wheel 8, both can ensure the steadily operation up and down of lift car, plays directional tagging, can prevent from again toppling over of whole device from playing equilibrium activity.
The utility model can be in the time that elevator has fault or other reasons to cause elevator tenesmus, and action in time, even in the time having a power failure, also can brake in time, realize the multiple safety protection of elevator, safe reliability is higher, conservative factor is larger, can effectively ensure elevator and contained personnel's safety.
