Description
Technical field
The present invention relates to elevator auxiliary device technical field more particularly to a kind of elevator buffer devices.
Background technique
Elevator is a kind of using motor as the vertical conveyor of power, also known as vertical lift, and vertical lift is hung equipped with box-like
Cabin multiplies people or carrying cargo for tier building.Elevator is the fixed type lifting equipment for serving regulation floor, is operated at least
Two column it is vertical or between rigid guideway of the inclination angle less than 15 °.Elevator with carriage, car size and structure type are just
In passenger's discrepancy or handling goods.
During elevator work, if lifting device breaks down, gently if lead to elevator stop motion, it is heavy then lead to elevator
It falls, brings life threat to passenger.
Buffer unit can be arranged in elevator bottom in present people, and when used during elevator falling, elevator is fallen to be filled in buffering
Enterprising row buffering is set, danger when falling is reduced, but this kind of buffer unit suffers from the drawback that 1. floors are higher, buffering dress
It is poorer to set buffering effect, when elevator is from when crossing high falling, under the effect of gravity, buffer unit will be more than that buffering carrying is online,
It directly damages, buffering effect is very little；2. immediately starting at the time of buffer unit cannot be damaged with elevator, can only passively delay
Punching, cannot actively start, cannot play a protective role at the first time.
Summary of the invention
The purpose of the present invention is to solve the bad disadvantages of elevator buffer device using effect in the prior art, and propose
A kind of elevator buffer device.
To achieve the goals above, present invention employs following technical solutions:
A kind of elevator buffer device is designed, the side wall including elevator and elevator two sides, elevator bottom is equipped with buffering
Device, the buffer unit include two the first fixed plates being placed in parallel for being fixed in elevator bottom, and two described first solid
It is equipped with reel between fixed board, is wound with flexible strand on the reel, the reel both ends are connected with line retaining disk, the gear
Drum another side is connected with shaft, and the shaft rotation connection is on the first fixing plate；Guaranteeing reel just by this kind of device
Often rotation.
Outer cylinder is connected with inside one of them described line retaining disk, outwardly, the outer barrel is inserted with the outer cylinder opening
Clamping bar, the clamping bar other end are plugged in the through-hole that the first fixed plate opens up；It is fixed since clamping bar is plugged in first
In plate, prevent reel from rotating.
First fixed plate is equipped with horizontal positioned cylinder far from the side of clamping bar, and the cylinder is solid by link block
It is scheduled on elevator bottom, the inner barrel is equipped with rotating bar, and the rotating bar both ends are rotatably connected on first be arranged in cylinder
On cross bar, the second cross bar, spiral plate is set in the rotating bar, the spiral plate outer rim and cylinder inboard wall are tangent,
The rotating bar is coaxially connected with gear far from one end of clamping bar, and the rack gear of vertical display is connected on the side wall of elevator,

The coaxial arrangement of clamping bar, the sliding block are connected with spring far from rotating bar on one side, and the spring other end is fixed in cylinder
Wall；
When elevator normally declines, by the engagement between gear, rack gear, rotate rotating bar, spiral
Plate and then rotates, and since spiral plate outer rim and cylinder inboard wall are tangent, air-flow is from cylinder close to one end of side wall to other end stream
Dynamic, air-flow is flowed out from stomata, and small part gas shock sliding block, impact force is absorbed by spring.
The flexible strand bottom end is hung with the block that falls, and the block two sides of falling pass through first axle and are connected with diagonally downward
The promotion connecting rod of setting, the promotion connecting rod bottom end are connected with pushing block by second hinge, and the elevator bottom is solid by second
Fixed board is connected with horizontal positioned bottom plate, and the pushing block is slidably connected on bottom plate, and the pushing block is far from the side for pushing connecting rod
It is connected with clamping block, the clamping block is corresponding with the side wall position of elevator.
When elevator damages dramatic decrease, rotating bar is rapidly rotated, and air-flow rapidly enters in cylinder, and air-flow is arranged beyond stomata
Tolerance, most of gas shock make sliding block drive pushrod movement on sliding block, and ram impacts clamping bar withdraws clamping bar outer
In cylinder, since the flexible strand bottom hung on reel has the block that falls, fall block sharp downward movement under the effect of gravity, passes through
The block that falls makes pushing block push clamping block movement to pushing connecting rod to apply a power, and two clamping blocks are stuck in two side walls
On, since elevator motion direction and the clamping block direction of motion are perpendicular, elevator is effectively prevented to continue to fall downwards.
Preferably, the clamping bar, which circumferentially rotates, is connected with several runners closely arranged, and is convenient for push rod by clamping bar

Both ends are rotatably connected to idler wheel.When clamping block is stuck in the moment of side wall, bottom plate will generate very big power to idler wheel, by this
Kind design method, keeps the bonding strength of pushing block and bottom plate bigger.
Preferably, the pushing block bottom surface is equipped with ball, and cushion, the cushion are equipped in the slideway that the bottom plate opens up
It is placed in above idler wheel, the design of ball is conducive to the sliding of pushing block, and the design of cushion plays certain buffer function, avoids pushing away
Block is detached from bottom plate.
Preferably, the block bottom of falling offers the cunning chamber being vertically arranged, and the cunning is intracavitary to be inserted with guide post, described
Guide post bottom end is fixed on bottom plate, and the block that prevents from falling during elevator motion is arbitrarily swung.
Preferably, the block bottom surface of falling is connected with the first permanent magnetic iron block, and the plate upper surface is connected with the second permanent magnetism
Iron block, first permanent magnetic iron block, the second permanent magnetic iron block mutually attract, and under magneticaction, the block that makes to fall falls speed faster, just
It is stuck on side wall in clamping block.
Preferably, the clamping block is equipped with clamping protrusion, the clamping protrusion and side wall close to the side of elevator side wall
The cone tank opened up on face matches, and is stuck on side wall convenient for clamping block.
A kind of elevator buffer device proposed by the present invention, beneficial effect are: the present apparatus is completed in the way of full machinery
The buffering and clamping fixed of elevator, the coefficient of stability is higher, moves since the present apparatus begins to clamping when used during elevator falling occurs
Make, used during elevator falling can be prevented in time, preferably protects the safety of passenger.
