The top of cat ladder lead is sequentially provided with stop pin axis hole and lower locking bearing pin.
It is further：The both sides of the cat ladder are additionally provided with handrail.
The position that the slide upper ear plate and slide lower ear plate contact with cat ladder lead is provided with wear-resistant sleeve.
The wear-resistant sleeve that one end of the wear-resistant sleeve is provided with outside slide upper ear plate and slide lower ear plate is raised, and upper and lower two
The individual wear-resistant sleeve is installed with the raised relative direction of wear-resistant sleeve, is provided with and is enclosed between the slide upper ear plate and slide lower ear plate
It is used to withstand the raised distance set of wear-resistant sleeve on cat ladder lead.
The utility model has advantages below：Climbing from locking handrail cat ladder of the present utility model for high-altitude drivers' cab
Ladder can be controlled lifting by operating personnel, by bearing pin and upper stop pin axis hole and lower locking pin shaft hole with the use of coming pair
The position of cat ladder is fixed, and realizes the conversion of cat ladder relative altitude under different demands, with ensure safety that cat ladder uses with
It is convenient.

Embodiment
A kind of locking handrail cat ladder, including for work high above the ground certainly for high-altitude drivers' cab as shown in Figures 1 to 4
Operating desk 2, the operating desk 2 are provided with driver's chair 1, and the side of the operating desk 2 is provided with cat ladder 4, and the cat ladder 4 is by setting
Put the cat ladder fixed mount 3 below operating desk 2 to be fixed, the cat ladder fixed mount 3 is provided with slide upper ear plate 9 and slide
Otic placode 10, the cat ladder lead 11 of the both sides of cat ladder 4 link together with slide upper ear plate 9 and slide lower ear plate 10；It is described
The top of cat ladder lead 11 is sequentially provided with stop pin axis hole 5 and lower locking bearing pin 6.The both sides of the cat ladder 4, which are additionally provided with, to be helped
Hand 12.Driver's chair and cat ladder fixed mount of the present utility model is both connected on operating desk, on the cat ladder lead of cat ladder both sides
Portion interval is provided with upper stop pin axis hole and lower locking pin shaft hole, by placing bearing pin in locking pin shaft hole up and down, leads to simultaneously
Cross slide upper ear plate and bearing pin to be used cooperatively to change the relative position of cat ladder and cat ladder fixed mount, during normal operation, bearing pin is
It is inserted in lower locking pin shaft hole, prevents from interfering during operation to raise the relative altitude of cat ladder, when operating personnel need
When getting off from operating desk, bearing pin, which is inserted in upper stop pin axis hole, makes bearing pin be stuck on slide upper ear plate, and cat ladder is with respect to cat ladder
Fixed mount is fallen while locks cat ladder and no longer falls, and the height that now cat ladder falls, which conforms exactly to operating personnel, to be needed to fall earthward
Height；When operating personnel need to climb on operating desk, bearing pin is still placed in stop pin axis hole, it is known that operating personnel
Bearing pin is taken out in the lower locking pin shaft hole of insertion from upper stop pin axis hole again after entering operating desk, slide upper ear plate is stuck in bearing pin
On, so as to raise the height of cat ladder.Cat ladder both sides are additionally provided with handrail, play auxiliary and safing effect.
A kind of locking handrail cat ladder certainly for high-altitude drivers' cab as shown in Figures 1 to 4, the He of slide upper ear plate 9
The position that slide lower ear plate 10 contacts with cat ladder lead 11 is provided with wear-resistant sleeve 7.One end of the wear-resistant sleeve 7, which is provided with, is located at slide
Wear-resistant sleeve projection 71 outside upper ear plate 9 and slide lower ear plate 10, upper and lower two wear-resistant sleeves 7 are relative with wear-resistant sleeve projection 71
Direction installation, between the slide upper ear plate 9 and slide lower ear plate 10 be provided be enclosed on cat ladder lead 11 be used for withstand it is resistance to
The distance set 8 of grinding set projection 71.Cat ladder from locking handrail cat ladder of the present utility model for high-altitude drivers' cab is when in use
The change often with cat ladder fixed mount generation relative position is needed, therefore under cat ladder cat ladder lead and slide upper ear plate and slide
Abrasion can be produced because often rubbing against between otic placode, cause device damage or service life reduction, therefore in slide upper ear plate and cunning
Terraced lower ear plate sets wear-resistant sleeve in the position that cat ladder lead contacts, and is sent out to place wear-resistant sleeve with the activity of cat ladder lead
Raw position movement, projection is set in one end of wear-resistant sleeve, and wear-resistant sleeve sets a raised terminal block under slide upper ear plate and slide
Play a part of limiting the motion in one direction of wear-resistant sleeve outside otic placode, in order to ensure the motion of both direction above and below wear-resistant sleeve quilt
Limitation, wear-resistant sleeve make two raised positions of wear-resistant sleeve on slide upper ear plate and slide lower ear plate close to each other when installing, simultaneously
Distance set is provided between two wear-resistant sleeve projections, is prevented resistance on wear-resistant sleeve whereabouts and the slide lower ear plate on slide upper ear plate
Grinding set rises, therefore can effectively ensure the fixation of wear-resistant sleeve position.
