Bottom soil fixing, the ladder pedestal are set there are two groove, and the groove imports the extension ladder, and the terraced two sides of the extension are equipped with
Hollow cleat stanchion is connected with stile between the hollow cleat stanchion, and the hollow cleat stanchion imports anti-folding reinforcing bar, the extension from top to bottom
Terraced upper end is fixedly connected with the ladder top, and the ladder top side penetrates the anti-folding reinforcing bar and fixes, the ladder top other side and base
Hole top is fixedly linked using attachment fastener, and described attachment fastener one end is welded and fixed with the ladder top, and the attachment fastener is another
One end is in 90 degree and bends and be equipped with hole to the right, and described hole penetrates fixed steel bars and fixes with foundation pit top.
In one preferred embodiment of the utility model, the stile is slidably connected with the hollow cleat stanchion level.
In one preferred embodiment of the utility model, is erect between the stile and be provided with telescopic strut.
In one preferred embodiment of the utility model, the stile both ends are equipped with foot-operated recess.
In one preferred embodiment of the utility model, it is connected with shaft between the extension ladder, to reach described
Extend the folding purpose of ladder.
The beneficial effects of the utility model are: the utility model passes through the fixation of terraced pedestal and ladder top, so that total
Be tightly combined at the top of bottom of foundation ditch and foundation pit, securely and reliably, by stile, telescopic rod and hollow cleat stanchion be slidably connected so that
Stile can be adjusted arbitrarily between the upper and lower away from using more convenient, while by the effect of anti-folding reinforcing bar so that entirely ladder is vertical
It is more firm not pliable on direction, by the rotation connection between extension ladder so that the more quick detachable placement of total.Simultaneously
Total is detachable, so that part is conveniently replaceable cleaning, improves service life.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings, in which:
Fig. 1 is a kind of structural schematic diagram of folding one preferred embodiment of reinforced foundation pit escape ladder of the utility model；
The components in the drawings are labeled as follows: 1, ladder top；2, terraced pedestal；3, extend ladder；4, groove；5, hollow cleat stanchion；6,
Stile；7, anti-folding reinforcing bar；8, attachment fastener；9, hole；10, telescopic rod.
Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Referring to Fig. 1, the utility model embodiment includes:
A kind of folding reinforced foundation pit escape ladder, including the terraced pedestal 2 of ladder top 1 and several extension ladders 3, the ladder bottom
Seat 2 squeezes into downwards fixed steel bars and bottom of foundation ditch soil fixing, and the ladder pedestal 2 is set there are two groove 4, and the groove 4 imports
The extension ladder 3, terraced 3 two sides of the extension are equipped with hollow cleat stanchion 5, are connected with stile 6, the sky between the hollow cleat stanchion 5
Heart cleat stanchion 5 imports anti-folding reinforcing bar 7 from top to bottom, and terraced 3 upper ends of the extension are fixedly connected with the ladder top 1,1 side of ladder top
It is fixed to penetrate the anti-folding reinforcing bar 2,1 other side of ladder top is fixedly linked with foundation pit top using attachment fastener 8, the fixation
