Description
Technical field
The present invention relates to the technical fields of ladder, more particularly, to a kind of elevator pit ladder and its application method.
Background technology
Ladder, daily life tools, the tool do side by two root long thick bar, and scansorial cross bar is crossed in centre, use
In climbing, ladder is divided into the single ladder of lifting and lifting double ladder.
Elevator pit is the minimum stop hoistway part below for being located at car service, interior to stop equipped with buffer and elevator
Only switch and hoistway lamp switch, power outlet and illumination；Pit door can be set on demand；Pit should have enough spaces；Cheat bottom with
Clearance between car lowermost portion is not less than 0.5m；Cheat bottom and guide shoe or idler wheel, safety tongs voussoir, toeguard or vertical
The clearance of slide unit cannot be less than 0.1m.Its bottom is answered smooth, is unable to ponding.Its structure should be able to bear car or
The compression strength of counter-force when counterweight is collided with buffer.
Existing elevator pit ladder design is simple, it has not been convenient to fold, safety coefficient is not high, and is inconvenient to operate.
Invention content
The present invention is at least one defect overcome described in the above-mentioned prior art, provides a kind of elevator pit ladder and its makes
With method, facilitates folding, efficiently use space.
The technical scheme is that：A kind of elevator pit ladder, wherein including ladder main body, be positioned on wall
Wall fixed part, first connecting rod, described first connecting rod one end is hinged with ladder main body, and the other end is hinged with wall fixed part；
Further include the ladder extension being set in ladder main body, the deck for positioning ladder extension；Also connect in ladder main body
Connect the driving mechanism that driving ladder main body folds.
In the present invention, by using driving mechanism so that ladder can foldable integral, it is very convenient.And staff needs
So that when ladder, ladder extension is pulled upwardly, is then pressed slightly downwards, deck can be made to block ladder extension, it is quickly fixed
Position and very firm stable.The working environment of this ladder must be used in sill top-operation, and the pull of step takes Y type decks
Structure has the function that flexible free, convenient, flexible.
Further, the driving mechanism include lead screw, the sliding block that is connect with lead screw, further include second connecting rod, it is described
Second connecting rod one end and sliding block it is hinged, the other end is hinged with ladder main body.The axis top of the lead screw is provided with for making
Tool passes through the through-hole of rotary screw rod.
In the present invention, for be applicable in this ladder by staff on hoistway（Hall door）Operation takes lead screw sliding block to release
Principle reaches the rational deployment for using and parking.So that tool is passed through rotary screw rod by through-hole, is moved down on lead screw driving sliding block
Dynamic, to which slider-actuated second connecting rod moves, second connecting rod drives the folding or expansion of ladder main body again.
Further, the first connecting rod is respectively arranged on the upper and lower part of ladder main body.Setting is so that ladder in this way
It is whole more steady.
Further, the ladder main body fold thicknesses are 65-70mm.Preferably, ladder main body fold thicknesses are
68mm。
Because elevator pit is almost otherwise fully engaged in the process up and down in car, fold thicknesses when this ladder packs up deactivated
68mm is no more than lading door dill width 70mm, rationally utilizes space.
A kind of application method of elevator pit ladder, includes the following steps：
S1. tool passes through through-hole rotary screw rod；
S2. sliding block is moved down along lead screw, drives second connecting rod, second connecting rod drives first connecting rod again, to drive ladder master
Body flexes outward；
S3. it pulls up ladder extension and makes it higher than platform；
S4. ladder extension is made to fix by the cross bar of deck clamping ladder main body again.
Compared with prior art, advantageous effect is：Effective solution of the present invention ele-vator shaft spaces are small, safety coefficient is low
The problems such as, by using driving mechanism so that ladder can foldable integral, it is very convenient.And staff is it is required that ladder
When, ladder extension is pulled upwardly, is then pressed slightly downwards, deck can be made to block ladder extension, quickly positioning and ten
Divide firm stable.The pull of step takes Y type cartridge structures, has the function that flexible free, convenient, flexible.
