The specific embodiment
Below the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on embodiment of the present utility model, those of ordinary skills belong to protection domain of the present utility model not making the every other embodiment that obtains under the creative work prerequisite.
The utility model embodiment provides a kind of folding protection cat ladder, can be used in the Construction of Steel Structure, as shown in Figure 1, 2, comprising: ladder and protect cage;
Wherein, the ladder top is provided with hook; Protect cage and be movably connected in (see figure 4) on the ladder by bolt, protect and shroud the front that ladder is stated in the residence, protecting cage can be along the folding positive (see figure 2) of described ladder that fits in after the bolt rotation that connects described ladder.
Further, as shown in Figure 3, the hook of above-mentioned ladder can be made of two steel column hooks that are arranged side by side, and hook is welded on described ladder top, and the weld length of hook on described ladder top is 250mm;
Further, ladder can be made of the montant of both sides and a plurality of horizontal treadle that is disposed between two montants, and the montant of both sides can be made of the strip flat steel bar, and montant back, ladder both sides is interval with leg, and leg is perpendicular to described montant (see figure 1).
In the further above-mentioned cat ladder, protect cage and constituted by a plurality of guard rings and the connecting rod that is connected between each guard ring that arranges at interval;
