Description
Technical field
A kind of contraction type ladder of the present invention, belongs to elevator technology field.
Background technology
With the progress and development of science and technology, aircraft, high ferro and subway have become a kind of vehicles of people's trip, and
And drive the fast development of elevator.But Sightseeing Lift turns into the preferred trapezoidal of airport, high ferro station and subway station, Sightseeing Lift is being protected
While demonstrate,proving quality and safety, also to accomplish beautiful, generous, exquisite.Wherein had to comply with into the ladder of pit " GB7588.1
It is middle require terraced frame or other suitable handrail length from the upward vertically extending height of landing sill be at least 1.1m ", see
Light ladder is mostly four sides Sightseeing Lift, and wherein handrail leakage influences attractive in appearance.For non-sightseeing type elevator, when ladder is arranged on layer door
Sill bottom, in running process of elevator, handrail can and car door sill interference.
The content of the invention
The technical problems to be solved by the invention are：It is simple in construction to provide one kind, safety and stability, adaptation headroom height are low
The counterweight frame of elevator hoistways.
For above technical problem, a kind of contraction type ladder of the present invention, there is pit side wall and be fixed on pit
Maintenance cat ladder in side wall, the both sides for overhauling cat ladder are provided with handrail, and maintenance cat ladder upper end, which is symmetrically arranged with, to be connected to maintenance and climb
Tumbler between ladder and handrail has to be arranged in the both sides of handrail is used for the jump ring for fixing handrail in pit side wall, examining
Repair and be symmetrically arranged with cat ladder when handrail deploys for the handrail fixture for fixing handrail, maintenance cat ladder, which has, to be symmetricly set on
Column in pit side wall and the crosspiece being connected between two heel posts, the both sides of the crosspiece, which have, stretches out maintenance cat ladder
Protuberance.
Preferably, tumbler has a connecting plate and tumbler, connecting plate has 2 pieces of metallic plates and through 2 blocks of metal
The connecting shaft of plate, the tumbler are socketed in connecting shaft, and the other end of tumbler is fixedly connected with handrail, one end of connecting plate
It is fixed on the column of maintenance cat ladder, the other end is connected by connecting shaft with handrail, and handrail can rotate along connecting shaft and edge turns
Moving part moves up and down.
Preferably, the quantity of tumbler is 2, it is respectively fixedly connected with the column of maintenance cat ladder both sides, rotates
Device is corresponding with the handrail of both sides, and the expansion of handrail and contraction are completed by tumbler, facilitates maintainer to enter elevator
Pit is attractive in appearance with guarantee sightseeing elevator.
Preferably, causing to interfere in order to avoid handrail overhauls maintenance personal cat ladder up and down, handrail fixture is arranged on
On the protuberance of crosspiece, quantity is 2.
Compared with prior art, usefulness of the present invention is：Maintainer need to only squat at doorway, rotary handle, make
It is fixed on handrail fixture, conveniently can be entered pit, be realized the maintenance operation of pit safety component；When not using ladder
The period of the day from 11 p.m. to 1 a.m, handrail need to be only fixed on jump ring, hidden function can be realized.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is contraction type ladder deployed condition structural representation；
Fig. 2 is contraction type ladder contraction state structural representation；
Fig. 3 is the structural representation of tumbler.
In figure：1st, pit side wall；11st, jump ring；2nd, cat ladder is overhauled；3rd, handrail；4th, tumbler；41st, connecting plate；411st, it is golden
Belong to plate；412nd, connecting shaft；42nd, tumbler；5th, handrail fixture；6th, column；7th, crosspiece；71st, protuberance.
Embodiment
A kind of contraction type ladder of the present invention, as depicted in figs. 1 and 2：With pit side wall 1 and it is arranged on pit side
Maintenance cat ladder 2 on wall 1, the left and right sides of maintenance cat ladder 2 is provided with handrail 3, wherein maintenance cat ladder 2 has column 6 and connection
Crosspiece 7 between column 6, the both sides of a crosspiece 7 are with the protuberance 71 for protruding maintenance cat ladder 2 wherein, in protuberance
The handrail fixture 5 for fixing handrail 3 is provided with 71, the rotation for connecting handrail 3 is fixed with maintenance cat ladder 2 both sides
Device 4.
Preferably,：The quantity of tumbler 4 is 2, and tumbler 4 has connecting plate 41
With tumbler 42, connecting plate 41 has 2 pieces of metallic plates 411 and the connecting shaft 412 through 2 pieces of metallic plates 411, and tumbler 42 is socketed
In connecting shaft 412, the other end of tumbler 42 is fixedly connected with handrail 3, and one end of connecting plate 41 is fixed on maintenance cat ladder 2
