Abstract
An emergent anti-dropping device of an elevator comprises a control device (1) and an anti-dropping device (2). The device has the advantages that the device has simple structure and can be modified on the basis of the existing elevator without adding great cost. Personal safety of users can be assured and accidents of elevator dropping can be reduced.
Description
Technical field
The utility model relates to the elevator technology field, a kind of specifically elevator emergency falling proof device.
Background technology
Along with the continuous development of urban construction, skyscraper is on the increase, elevator thereby be widely used, and it is inseparable with daily life as the vehicle of vertical operation in the skyscraper.But in a single day elevator has an accident, when falling rapidly, will produce harm greatly even threat to life to people's physical and mental health.
Elevator brake or safety tongs (being safety device) are installed in the existing elevator, and most elevator device all can there be a bumper of fixing with ground in the hoistway bottom.When down falling rapidly at et out of order, the safety device in the elevator is opened, and it can pin the elevator of up-and-down movement in hoistway.When elevator dropped down onto the hoistway bottom, the bumper that fixes on the ground can play certain buffer action.Even so, some elevator is in bad repair with age, and elevator safety device loses effect, and the buffer action that the bumper that fixes on the ground can play is also limited, and personal safety is brought threat.
The utility model content
The purpose of this utility model be design a kind of under the situation that original safety device lost efficacy, can make elevator safety operation, improve the elevator emergency falling proof device of elevator safety coefficient.
The utility model elevator emergency falling proof device comprises: control setup 1 and anti-fall device 2.
Buffer rack 9 comprises: be fixed on the connection support 14 of outside, elevator room top, and be connected the flexible grade post 15 that support 14 links to each other.
The utility model elevator emergency falling proof device prevents to fall and is achieved in that when elevator falls rapidly, bead 5 is in state of weightlessness, rise to conducting film 7 places of insulating cylinder 6, switch on, motor 8 starts running, drives turning cylinder 13 and rotates, and the pin 11 that is contained on the turning cylinder 13 moves to and the previous status upright position, the flexible shelves post 15 of buffer rack 9 is fallen on the pin 11, and deceleration of elevator is until stopping; Behind the static trouble-shooting of elevator, bead 5 comes back to and is subjected to gravity state, break away from conducting film 7, circuit disconnects, the motor 8 of all the other floors cuts out, and pin 11 is return under the effect of spring 12, as long as start elevator, support pin 11 return under the effect of spring 12 of this elevator, elevator can recover normal operation.If certain one deck is not because the time difference is blocked, following one deck is bound to block, and has improved the safety control coefficient when elevator drops.
The advantage of the utility model elevator emergency falling proof device is: simple in structure, can on existing elevator basis, transform, and need not increase very big cost, ensure user's personal safety, reduce the generation of used during elevator falling accident.
Description of drawings
Accompanying drawing is the structural representation of elevator emergency falling proof device.
Specific embodiments
With reference to the accompanying drawings, the elevator emergency falling proof device comprises: control setup 1 and anti-fall device 2.
Buffer rack 9 comprises: be fixed on the connection support 14 of outside, elevator room top, and be connected the flexible grade post 15 that support 14 links to each other.
