In this utility model, by the design of two elevator doors etc., it is to avoid the accident that car surprisingly lifts and occurs；Designed by buffer cell and detector unit, cage descending, convenient rescue can be stoped when steel wire rope surprisingly ruptures timely；Elevator structure is simple, uses conveniently, safely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the top view of car of the present utility model.
Detailed description of the invention
With reference to Fig. 1,2:
Fig. 1 is that this cylinder 10 drives the structural representation that gripper shoe 11 rotates after cylinder 10 is energized；Under normal circumstances, gripper shoe 11 houses with in through hole 9, does not affect the rising of car 1.
The utility model proposes a kind of is prevented from the elevator that car surprisingly rises or falls, including car 1, drive mechanism 2, two elevator doors 3, pillars 4, this pillar 4 is vertically arranged, two elevator doors 3 are distributed in the both sides of pillar 4, two elevator doors 3 are connected with pillar 4 loose-leaf system, and this drive mechanism 2 drives two elevator doors 3 to be turned out car 1 centered by pillar 4 and opens.
Allow elevator door 3 by above-mentioned design, there is some benefit following:
When one, opening the door, elevator door 3 need not slide to both sides, reduces the width of hoistway, cost-effective.
Rising or falling if two cars 1 are unexpected, elevator door 3 is placed in floor and stops mouth A, at this moment, it is possible to use elevator door 3 supports the weight of car 1, it is to avoid occur unexpectedly, also makes a response for people and strives for valuable time.
Three, by arranging two elevator doors 3, can do into people respectively, go out people's use, so, people do not interfere with when passing in and out car 1, convenient.
This elevator also includes steel wire rope 5, hoist engine 6, guide rail 7, and this guide rail 7 is vertically arranged, and this car 1 is connected with guide rail 7 rolling by the roller 8 matched with guide rail 7, and this steel wire rope 5 one end is connected with car 1, and the other end is connected with hoist engine 6；
This guide rail 7 is vertically interval with some through holes 9；Certainly, the size of through hole 9 can not be excessive, it is impossible to affects the normal lifting of roller 7；
This elevator also includes buffer cell and detector unit；
This buffer cell includes cylinder 10, gripper shoe 11, and this cylinder 10 is in transmission connection with gripper shoe 11, and the size of this gripper shoe 11 matches with through hole 9, and one end of this gripper shoe 11 is rotationally connected with through hole 9；
After the energising of this cylinder 10, this cylinder 10 drives gripper shoe 11 to rotate through through hole 9 to car 1 direction centered by gripper shoe 11 with the junction of through hole 9；
This detector unit includes connecting rod 12, spring 13, this connecting rod 12 is connected with steel wire rope 5, this connecting rod 12 be provided with the first conductor 14, the lower section of this first conductor 14 is provided with the second conductor 15, this second conductor 15 is arranged on car 1, and one end of this spring 13 is connected with the first conductor 14, and the other end and the second conductor 15 connect, this first conductor 14 electrically connects with external power source, and this second conductor 15 electrically connects with cylinder 10；
By the pulling force of steel wire rope 5, connecting rod 12 rises, and after this connecting rod 12 rises, this first conductor 14, second conductor 15 separates, and the distance at these spring 13 two ends is more than its natural length；
After steel wire rope 5 fracture, the active force lower link 12 at spring 13 quickly declines, and declines the acceleration acceleration more than car, and after this connecting rod 12 declines, this first conductor 14, second conductor 15 turns on.
When steel wire rope 5 ruptures, cylinder 10 is energized, gripper shoe 11 is driven to rotate, gripper shoe 11 contacts with roller 8, distance between gripper shoe 11 and roller 8 is gradually reduced, and with reference to Fig. 1, roller 8 can not be to car 1 direction horizontal displacement under the effect of guide rail 7, gripper shoe 11 coordinates prevention roller 8 to continue to decline with guide rail 7, effectively avoids accidents.
This through hole 9 and floor are stopped mouth A and are correspondingly arranged, and the quantity of buffer cell is multiple；After car 1 is stopped, conveniently stop mouth A from floor and car 1 is rescued；By arranging multiple buffer cell, after steel wire rope 5 fracture, it is possible to utilize neighbouring buffer cell to rescue timely, reduce the dropping distance of car 1, also reduce the abrasion of roller 8 and gripper shoe 11.
This gripper shoe 11 is vertically arranged, and the top of this gripper shoe 11 is rotationally connected with through hole 9；Because one end of gripper shoe 11 is fixed with through hole 9, after steel wire rope 5 fracture, gripper shoe 11 rotates, and gripper shoe 11 one-tenth is obliquely installed, and the distance between roller 8 is gradually reduced, and so can slow down the impulsive force between roller 8 and gripper shoe 11, reduces and damages.
This through hole 9 is positioned on the sidewall that guide rail 7 contacts with the peripheral side of roller 8, and the surface on surface and above-mentioned sidewall that this gripper shoe 11 is positioned at car 1 side overlaps, and this gripper shoe 11 and through hole 9 are along bearing of trend equal sized of guide rail 7；If above-mentioned design, do not affect the normal lifting of roller 8.
The scope of this embodiment detection is relatively big, as long as the steel wire rope 5 between connecting rod 12 and hoist engine 6 can detect whether it ruptures.
The above; it is only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; conceive equivalent or change in addition according to the technical solution of the utility model and utility model thereof, all should contain within protection domain of the present utility model.
