Description

A kind of cat ladder for elevator hoistways

Technical field

This utility model relates to a kind of cat ladder ascended a height when repair and maintenance, refers more particularly to a kind of for elevator The cat ladder in road.

Background technology

At present, a kind of traditional cat ladder for elevator hoistways, its structure generally includes: a pair vertical rod and some connect this The cross bar being equally spaced of a pair vertical rod, every vertical rod is generally all welded on well enclosure by fixing connector.Actual During making, vertical rod and cross bar the most all use angle bar to make.During life-time service, vertical rod and cross bar are easy to get rusty, many Well known, the cat ladder after getting rusty, its intensity will be greatly reduced, thus causes this cat ladder to there is serious potential safety hazard.And And, owing to cat ladder is integrally fixed on well enclosure, when cat ladder get rusty need afterwards change time, dismounting bother very much.

Utility model content

Technical problem to be solved in the utility model is: provide a kind of dismounting climbing for elevator hoistways very easily Ladder.

For solving above-mentioned technical problem, a kind of cat ladder for elevator hoistways that this utility model uses, its structure includes: A pair vertical rod and some these cross bars to vertical rod of connection, every vertical rod is provided with at least one for vertical rod being fixed on Active connection on hoistway.

As a kind of preferred version, described a kind of in the cat ladder of elevator hoistways, described connector includes: phase The most vertical hoistway connecting portion and vertical rod connecting portion, vertical rod connecting portion is fixing with vertical rod to be connected, and hoistway connecting portion offers length Bar hole.

As a kind of preferred version, described a kind of in the cat ladder of elevator hoistways, described vertical rod is hollow knot Structure, the both sides sidewall of its one end offers through connecting hole.

As a kind of preferred version, described a kind of in the cat ladder of elevator hoistways, the upper and lower both sides of described cross bar Side on be provided with anti-skid structure.

As a kind of preferred version, described a kind of in the cat ladder of elevator hoistways, described anti-skid structure includes: The bar shaped convex tendon that some the length directions along cross bar are arranged.

As a kind of preferred version, described a kind of in the cat ladder of elevator hoistways, the horizontal stroke of described bar shaped convex tendon The profile in cross section is circular arc.

As a kind of preferred version, described a kind of in the cat ladder of elevator hoistways, described vertical rod is away from even Connect and on the other end in hole, be provided with buffer cap.

The beneficial effects of the utility model are: this utility model is owing to have employed active connection so that the dismounting of cat ladder Very convenient；Further, owing to offering elongate holes on hoistway connecting portion, the position of cat ladder can be adjusted when installing cat ladder, The most generous installation having made cat ladder.Additionally, due to be provided with bar shaped convex tendon, a side on the side of the upper and lower both sides of cross bar Face adds the intensity of cross bar, on the other hand can be effectively prevented climbing personnel's sole and skid, be to kill two birds with one stone.It addition, by It is hollow structure in vertical rod, the both sides sidewall of its one end offers through connecting hole, thus can be logical according to actual needs Cross splicing connecting piece to be stitched together by a pair cat ladder, extend the height of cat ladder, thus significantly widened its application scenario.

Detailed description of the invention

Below in conjunction with the accompanying drawings, being embodied as of a kind of cat ladder for elevator hoistways described in the utility model is described in detail Scheme:

As it is shown in figure 1, a kind of cat ladder for elevator hoistways described in the utility model, including: a pair vertical rod 1 and some Root connects this cross bar 2 to vertical rod, and cross bar 2 is generally all equally spaced, depending on its quantity can be according to practical situation, and every (quantity of active connection 3 can basis for the active connection 3 that vertical rod 1 is fixed on hoistway to be provided with a pair in vertical rod 1 Depending on practical situation), as shown in Figure 6, the concrete structure of this active connection 3 includes: orthogonal hoistway connecting portion 31 He Vertical rod connecting portion 32, this vertical rod connecting portion 32 offers a pair connecting hole 321, described vertical rod 1 offers with this to even Connect hole 321 connecting hole one to one, vertical rod connecting portion 32 and vertical rod 1 to be fixed together by bolt, pad and nut, well The elongate holes 311 that the expansion bolt 4 offered on road connecting portion 31 and be fixed on well enclosure matches--see Fig. 3 institute Show.In the present embodiment, described vertical rod 1 is hollow structure, the both sides sidewall of its one end offers through connecting hole 11, separately Buffer cap 9 as shown in Figure 7 it is arranged with on one end；In addition, as shown in Figure 4, Figure 5, in order to make cat ladder stand upside down or upright Time all there is antiskid function, the side of the upper and lower both sides of described cross bar 2 is provided with anti-skid structure, this anti-skid structure Concrete structure includes: the bar shaped convex tendon 21 that some the length directions along cross bar 2 are arranged, the cross section of this bar shaped convex tendon 21 Profile is circular arc.

When reality is applied, described vertical rod 1 and cross bar 2 are made by aluminium alloy, overcome because being in elevator for a long time The problem of rustiness caused in road.

Time actually used, the cat ladder of a pair structure described in the utility model can be bolted together and makes according to actual needs With, to extend the height of cat ladder, widen its application scenario.First, making a pair cat ladder for splicing, this is on cat ladder The installation direction contrast of active connection 3, then, by shown in Fig. 2 offer a pair with this vertical rod 1 end to cat ladder Cat ladder is stitched together by splicing connecting piece 5 and bolt, nut and the pad of the through hole that the connecting hole 11 in portion matches by this, As it is shown on figure 3, spliced a pair cat ladder, its active connection 3 is positioned at the same side.

In sum, preferred embodiment the most of the present utility model, not it is used for limiting what this utility model was implemented Scope, all equivalent variations made according to shape, structure, feature and the spirit described in this utility model right with repair Decorations, all should be included in right of the present utility model.
