Utility model content
The purpose of this utility model is to provide a kind of safety climbing ladder, and this safety climbing ladder can significantly improve the security performance of cat ladder, thus ensures healthy when operation of operating personnel.
For solving the problems of the technologies described above, the utility model provides a kind of safety climbing ladder, comprise four bases, the top of described base is provided with cat ladder frame, described cat ladder frame comprises the montant and cross bar that connect successively, the bottom of described cat ladder frame is provided with the passway that can enter for people, the inside of described cat ladder frame is provided with stair, the side of described stair is provided with handrail, the side of the platform of marking time of described stair is provided with limit guardrail, and the outside of described cat ladder frame is provided with the diagonal member for increasing structural stability.
Preferably, described limit guardrail hooks on cross bar described in two of the platform place of marking time being in described stair.
Preferably, the both sides of the platform of marking time of described stair are all provided with described limit guardrail.
Preferably, described diagonal member is arranged on marking time between platform of two-layer described stair.
Preferably, the inside of described cat ladder frame is provided with stull, and described stair are arranged in described stull.
Preferably, the inside of described cat ladder frame is often provided with a described stull apart from 1.5 meters.
Preferably, described limit guardrail is latticed limit guardrail.
The safety climbing ladder that the utility model provides, cat ladder in prior art, is provided with limit guardrail at the platform place of marking time of stair, thus prevents the operating personnel when constructing from falling down from the space being in platform of marking time, namely fall down from the space between cross bar and cross bar, ensure that the safety of operating personnel.
In a preferred embodiment, limit guardrail hooks marks time on two cross bars at platform place what be in stair, and limit guardrail is latticed limit guardrail, thus the space between two cross bars being in platform place of marking time is blocked by limit guardrail, fully ensure that operating personnel's is healthy.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The elevation of safety climbing ladder when not filling protective guard that Fig. 1 provides for the utility model embodiment;
The lateral view of safety climbing ladder when not filling protective guard that Fig. 2 provides for the utility model embodiment.
Detailed description of the invention
Core of the present utility model is to provide a kind of safety climbing ladder, and this safety climbing ladder can significantly improve the security performance of cat ladder, thus ensures healthy when operation of operating personnel.
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See the elevation of safety climbing ladder when not filling protective guard that Fig. 1 and Fig. 2, Fig. 1 provide for the utility model embodiment; The lateral view of safety climbing ladder when not filling protective guard that Fig. 2 provides for the utility model embodiment.
The safety climbing ladder that the utility model embodiment provides, comprise four bases 1, the top of base 1 is provided with cat ladder frame, cat ladder frame comprises the montant 2 and cross bar 3 that connect successively, the bottom of cat ladder frame is provided with the passway that can enter for people, and the inside of cat ladder frame is provided with stair 4, and the side of stair 4 is provided with handrail 5, the side of the platform of marking time of stair 4 is provided with limit guardrail, and the outside of cat ladder frame is provided with the diagonal member 6 for increasing structural stability.
The safety climbing ladder that the utility model embodiment provides, compared to cat ladder of the prior art, at the platform place of marking time of stair 4, limit guardrail is installed, thus prevent the operating personnel when constructing from falling down from the space being in platform of marking time, namely fall down from the space between cross bar 3 and cross bar 3, ensure that the safety of operating personnel.
Due in cat ladder, stair 4 are not straight-through tops, but as the stair that our floor gap uses, between two-layer stair 4, have platform, are the platform of marking time of above-mentioned stair 4.
On concrete or steel plate, 4 support with adjustables 1 are installed, namely bearing 1 position with highly can select, use level gauge copy absolute altitude, make 4 bearings 1 be in same plane and formed a rectangle, difference grafting montant 2 on four bearings 4, montant 2 and cross bar 3 are all provided with the latch storehouse for grafting latch, with latch, cross bar 3 and montant 2 are linked together, finally form an overall cat ladder frame, and latch is provided with stopping device, prevent latch from withdrawing.
Further, limit guardrail hooks on two cross bars 3 at platform place of marking time being in stair 4, and namely hooking on the cross bar 3 at platform place of marking time being in stair 4 has limit guardrail, limit guardrail is provided with the crotch that can catch on cross bar 3, certainly, limit guardrail also can hook on diagonal member 6.
In the both sides of the platform of marking time of stair 4, limit guardrail can be all installed.
Further, what diagonal member 6 was arranged on two-layer stair 4 marks time between platform, makes the platform of marking time of itself and stair 4 jointly increase the stability of structure.
Further, in the inside of cat ladder frame, stull can be installed, stair 4 arrange in stull, stull can be welded by angle steel, in the inside of cat ladder frame, often distance 1.5 meters is provided with a stull, and do not make cross bar 3 at bottom one deck of the width of whole cat ladder frame, first stull is arranged on herein, on the first stull, three roads do not make cross bar 3, thus as passway.
Above-mentioned limit guardrail can be latticed limit guardrail, and certain above-mentioned limit guardrail also can be the limit guardrail of other structures, as the limit guardrail of triangular structure.
Mounting distance between above-mentioned cross bar 3 and cross bar 3 is up arranged by 0.5m one deck, and the height of whole cat ladder can reach 21m, and the supporting screw of handrail 5, nut are fixed on the inner side of stair 4.
When cat ladder is connected with wall, cat ladder frame often raises 3m can arrange one wall connecting rod part, is connected with montant 2.
