Abstract
The utility model relates to a ladder, in particular to a single-pole elevator shaft ladder. The elevator shaft ladder is provided to mainly solve the problem of high material consumption in the prior art. In order to solve the technical problem, the elevator shaft ladder adopts the technical scheme as follows: the elevator shaft ladder comprises a lifting main pole, climbing step nails distributed in the longwise direction of the main pole and fixedly connected with the main pole, and connecting plates fixedly connected on the main pole and used for fixing the ladder inside an elevator shaft. The single-pole elevator shaft ladder has the advantages of simple structure and small volume, and saves materials and space.
Description
Technical field:
The utility model relates to a kind of cat ladder, relates in particular to a kind of elevator hoistways cat ladder of single pole.
Background technology:
Traditional cat ladder is generally two vertical rods, and the centre adds the structure of cross bar, though solid, materials are also many.China's utility model patent 200720024542.8 discloses a kind of safe cat ladder, its structure is: mainly be made up of cat ladder vertical rod, cat ladder pawl, cat ladder connector, the cat ladder vertical rod is provided with two, the cat ladder pawl is connected between the cat ladder vertical rod, set up a cat ladder handrail in a side of cat ladder vertical rod, the cat ladder handrail links together by welding and cat ladder vertical rod.This safe cat ladder is an a kind of pair of bar cat ladder, though solid, how materials also take up space very much.
Summary of the invention:
The utility model has mainly solved the many problems of materials in the above-mentioned prior art, and a kind of elevator hoistways cat ladder is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of elevator hoistways cat ladder, comprise a cat ladder mobile jib, along the cat ladder of fixedlying connected arranged on the length direction of mobile jib step nail and be fixedly connected on the mobile jib junction plate that cat ladder is fixed in the elevator hoistways with mobile jib.
As a kind of preferred version of such scheme, between described mobile jib and each junction plate, be provided with connecting rod, an end of connecting rod is fixedlyed connected with mobile jib, and the other end is fixedlyed connected with junction plate.
As a kind of preferred version of such scheme, cat ladder step nail is arranged in parallel, and the cat ladder step middle part of nail is arranged on the mobile jib.
As a kind of preferred version of such scheme, the described cat ladder step follows closely symmetry or is crisscross arranged in the mobile jib both sides.The cat ladder step follows closely and is staggered setting in this preferred version, and this structure is compared common cat ladder and saved the material of half, has reduced cost.
As a kind of preferred version of such scheme, described cat ladder step nail is upturned away from mobile jib one end.Be convenient to staff's climbing.
The utility model has the advantages that simple in structurely, volume is little, has saved material and space.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of side-looking structural representation of Fig. 1;
Fig. 3 is an another kind of structural representation of the present utility model.
The specific embodiment:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described.
Embodiment 1:
According to illustrated in figures 1 and 2, the utility model cat ladder comprises a cat ladder mobile jib 1, is staggeredly equipped with cat ladder step nail 2 on cat ladder mobile jib both sides, and this cat ladder step nail inserts in the mobile jib, by welding fixing or passing through bolt, cat ladder step nail is upturned away from mobile jib one end then; On mobile jib, also be provided with connecting rod 4, the connecting rod end is provided with and is used for the cat ladder mobile jib is fixed on junction plate 3 in the elevator hoistways, needs according to the fabricating yard, this junction plate can or be bolted on the fixing body by welding, when using bolt, junction plate is provided with installing hole, and bolt generally adopts expansion bolt.
Embodiment 2:
According to shown in Figure 3, the utility model has provided another kind of structure, comprise a cat ladder mobile jib 1, be symmetrically arranged with cat ladder step nail 2 on the mobile jib both sides, this cat ladder step nail inserts in the mobile jib, then by welding fixing or passing through bolt, certainly the cat ladder step nail that is arranged on the mobile jib both sides can be a cat ladder step nail, this cat ladder step nail passes mobile jib, and is fixing by bolt or welding then, perhaps directly fixing with the mobile jib welding by the middle part of cat ladder step nail.Other structures are identical with embodiment 1.
Specific embodiment described herein only is that the present invention's spirit is illustrated.The technician of the technical field of the invention can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
Although this paper has used mobile jib morely, the possibility of using other term do not got rid of in terms such as cat ladder step nail, connecting rod, junction plate.Using these terms only is in order to describe and explain essence of the present invention more easily; They are construed to any additional restriction all is contrary with spirit of the present invention.
