Abstract
The utility model discloses a kind of emergency staircase with triple buffer, car is connected with traction apparatuss by chain, and traction apparatuss are located in machine room, the bottom of described hoistway is provided with the grains of sand, the upside of the described grains of sand is provided with the buffer board of level, and between buffer board and hoistway, leave out the gap of sand, it is equipped with vertical chute on the side wall of the bottom of described hoistway four, described chute is plugged with slide block, and the inner of slide block is connected with buffer board, it is uniformly provided with spring, the upper end of described buffer board is provided with buffer between described buffer board and the bottom of hoistway.When car falls, touch buffer first, so buffer plays ground floor cushioning effect, and then buffer board pushes, and spring plays the second weight cushioning effect, then the grains of sand are extruded, flow out with going out husky hole from circumference, play triple buffer effect, therefore, triple buffer acts on, and greatly improves buffering effect and the security performance of elevator.
Description
Technical field
This utility model is related to elevator safety technical field, specially a kind of emergency staircase with triple buffer.
Background technology
The a lot of cell of elevator has, and is easy to people upstairs, gives people to save the time, but, elevator accident frequency in recent years
Send out, there is potential safety hazard, therefore, the safety of elevator is critically important, elevator is from high falling, without buffer unit, the inside
People is likely to get killed, and the elevator on market also has buffer unit, but, an only buffer, buffering effect not enough,
For this reason, we design a kind of emergency staircase with triple buffer.
Utility model content
The purpose of this utility model is to provide a kind of emergency staircase with triple buffer, to solve above-mentioned background technology
The problem of middle proposition.
For achieving the above object, this utility model provides following technical scheme：
A kind of emergency staircase with triple buffer, including hoistway, the left end of described hoistway is vertically provided with many
Individual door opening, is provided with car in described hoistway, and car is connected with traction apparatuss by chain, and traction apparatuss are located in machine room,
The bottom of described hoistway is provided with the grains of sand, and the upside of the described grains of sand is provided with the buffer board of level, and leaves between buffer board and hoistway
Go out the gap of sand, the bottom four side wall of described hoistway is equipped with vertical chute, described chute is plugged with slide block, and slide block
The inner be connected with buffer board, be uniformly provided with spring between described buffer board and the bottom of hoistway, the upper end of described buffer board sets
There is buffer.
Preferably, the door head beam of described door opening is equipped with armored concrete.
Preferably, it is provided with the illuminating lamp of Chang Liang in described hoistway.
Preferably, described buffer board is uniformly provided with out husky hole.
Compared with prior art, the beneficial effects of the utility model are：This has the emergency staircase of triple buffer, and car falls
When lower, touch buffer first, such buffer plays ground floor cushioning effect, then buffer board pushes, spring plays
Double cushioning effect, then the grains of sand be extruded, from circumference with go out husky hole and flow out, play triple buffer effect, therefore, San Chonghuan
Punching acts on, and greatly improves buffering effect and the security performance of elevator.
Brief description
Fig. 1 is this utility model structural representation；
Fig. 2 is A schematic enlarged-scale view of the present utility model；
Fig. 3 is hoistway top view of the present utility model.
In figure：1 hoistway, 2 door openings, 3 cars, 4 chains, 5 traction apparatuss, 6 grains of sand, 7 buffer boards, 8 chutes, 9 slide blocks, 10 bullets
Spring, 11 buffers.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1-3, this utility model provides a kind of technical scheme：
A kind of emergency staircase with triple buffer, including hoistway 1, is provided with the illuminating lamp of Chang Liang in hoistway 1, hoistway 1
Left end is vertically provided with multiple door openings 2, and the door head beam of door opening 2 is equipped with armored concrete, more solid, in hoistway 1
It is provided with car 3, and car 3 is connected with traction apparatuss 5 by chain 4, and traction apparatuss 5 are located in machine room, the bottom of hoistway 1 sets
There are the grains of sand 6.
The upside of the grains of sand 6 is provided with the buffer board 7 of level, and leaves out husky gap between buffer board 7 and hoistway 1, buffering
Husky hole is uniformly provided with out on plate 7, buffering effect more preferably, the bottom four side wall of hoistway 1 is equipped with vertical chute 8, chute 8
It is plugged with slide block 9, and the inner of slide block 9 is connected with buffer board 7, is uniformly provided with spring between the bottom of buffer board 7 and hoistway 1
10, the upper end of buffer board 7 is provided with buffer 11.
This has the emergency staircase of triple buffer, when car 3 falls, touches buffer 11, such buffer 11 first
Play ground floor cushioning effect, then buffer board 7 pushes, spring 10 plays the second weight cushioning effect, then the grains of sand 6 are extruded,
Flow out with going out husky hole from circumference, play triple buffer effect, therefore, triple buffer acts on, greatly improve the slow of elevator
Rush effect and security performance.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with multiple changes in the case of without departing from principle of the present utility model and spirit, repair
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
