Amount, protects human body not injured.
At present, in existing elevator, after steel wire rope is broken, elevator does the movement of falling object, and the speed of elevator can be increasingly
Soon, elevator at a high speed knocks buffer, and elevator is stopped by rapidly moving to, and impact is larger, even if being provided with buffering in pit
Device also not necessarily ensures the safety of human body, particularly with being injured more for this kind of special population such as old man, children and disabled person
Greatly.
Utility model content
The defects of for the prior art, the purpose of this utility model are to provide a kind of emergency staircase, can reduce elevator car
Compartment knocks the initial velocity of buffer, ensures the safety of human body in car.
The above-mentioned technical purpose of the utility model technical scheme is that：A kind of emergency staircase, bag
It includes car, car guide rail, be located on the car and the matched guide shoe of the car guide rail, the buffer being located in pit,
It is characterized in that, further include the deceleration device for slowing down before buffer acts to the car；The dress that slows down
It puts including being arranged on the vertical guide in pit, the guide groove being located in the vertical guide, the slip being stuck in the guide groove
Block, be located on well enclosure and positioned at the car guide rail both sides a pair of of guide roller, be fixedly connected on the sliding shoe and
The weight block and set that the steel wire rope being suspended on respectively on the corresponding guide roller is connected with the corresponding steel wire rope other end
In the cage bottom pressing the briquetting that the sliding shoe moves down.
Preferably, the weight block includes multiple hanging blocks, is connected between the hanging block by connecting rope.
Preferably, the guide groove tilts from top to bottom to the car guide rail.
Preferably, the sliding shoe includes body, sets on the body and guide groove cooperation sliding part, sets
On the body for stop the briquetting so that the car occur laterally offset blocking portion.
Preferably, the hanging block includes casting pig.
Preferably, the cross section of the guide groove is C-shaped.
In conclusion the invention has the advantages that：
The initial velocity that lift car knocks buffer can be reduced, ensures the safety of human body in car.
Description of the drawings
Fig. 1 is the structure diagram of one embodiment 1 of the utility model；
Fig. 2 is the structure schematic diagram of sliding shoe.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only explanation to the utility model, is not the limitation to the utility model, ability
Field technique personnel can as needed make the present embodiment the modification of no creative contribution after this specification is read, but
As long as it is all protected in the right of the utility model be subject to Patent Law.
Embodiment 1：As Figure 1-Figure 2, a kind of emergency staircase including car 1, car guide rail 2, is located at the car 1
Upper and the 2 matched guide shoe 3 of car guide rail, the buffer 4 being located in pit, which is characterized in that further include for slow
Rush the deceleration device 5 to slow down before device 4 acts to the car 1；The deceleration device 5 includes being arranged on vertical in pit
Guide rail 51, the guide groove 52 being located in the vertical guide 51, are located at well enclosure at the sliding shoe 53 being stuck in the guide groove 52
A pair of of guide roller 54 that is upper and being located at 2 both sides of car guide rail is fixedly connected on the sliding shoe 53 and hangs respectively
The weight block 56 and set that steel wire rope 55 on the corresponding guide roller 54 is connected with corresponding 55 other end of steel wire rope
In 1 bottom of car pressing the briquetting 57 that the sliding shoe 53 moves down.During installation, avoid vertical guide 51, slide
Block 53, weight block 56, steel wire rope 55, guide roller 54 are mounted on the underface of car, should be mounted on covering for 1 vertical projection of car
Outside lid scope, the quantity of car guide rail 2 is 2, and the upper surface and lower face of car 1 are both provided with guide shoe 3；Preferably, slow down
The quantity of device 5 is 2, using the perpendicular bisector of car guide rail 2 as symmetrical centre, is symmetrically disposed on the both sides of car 1.When elevator
After steel wire rope is broken, 1 movement of falling object of car after briquetting 57 and sliding shoe 53 contact of 1 bottom of car, presses sliding shoe
53 move downward along guide groove 52, and sliding shoe 53, which moves downward, pulls weight block 56 to rise, and the acceleration of car 1 becomes at this time
Small, the initial velocity that car 1 knocks buffer becomes smaller, and buffer 4 becomes smaller to the impact of human body, ensures the peace of human body in car
Entirely.
Preferably, the weight block 56 includes multiple hanging blocks 561, is connected between the hanging block 561 by connecting rope 562
It connects.If weight block 56 is whole one piece, be equivalent to suddenly to car 1 one it is upward more energetically, can bring unexpected fast
Prompt drop speed can bring injury to human body, multiple hanging blocks 561 connected by connecting rope 562 be used in the present embodiment, to car
1 power applied progressively increases to the weight of multiple hanging blocks 561 for the weight of 1 hanging block 561, and reduction of speed is more gentle, favorably
In protection human body.
Preferably, the guide groove 52 tilts from top to bottom to the car guide rail 2.
Preferably, the sliding shoe 53 include body 531, be located on the body 531 and the guide groove 52 coordinate
Sliding part 532, be located on the body 531 for stopping the briquetting 57 so that laterally offset occurs for the car 1
Blocking portion 533.This is set so that drives briquetting 57 and car 1 that sidesway occurs when sliding shoe 53 moves down, so that leading
CONTACT WITH FRICTION occurs for boots 3 and guide rail 2, further reduces the acceleration of car 1, and car 1 knocks the initial velocity of buffer into one
Step becomes smaller, and buffer 4 becomes smaller to the impact of human body, ensures the safety of human body in car.
Preferably, the hanging block 561 includes casting pig.
Preferably, the cross section of the guide groove 52 is C-shaped.Sliding shoe 53 can be stuck in guide groove 52 by the shape,
