Abstract
The utility model relates to an engineering crawling ladder which comprises a plurality of two lines of vertical rod brackets, a safety fence and a plurality of transverse support pedal plates, wherein the transverse support pedal plates are evenly and transversely connected between two lines of the vertical rod brackets, the lower ends of two symmetrical vertical rod brackets which are arranged at the lowest bottom end are respectively provided with a piston, the pistons are fixed on the ground by a plurality of L-shaped equilateral steel angles, one side of the safety fence which encloses the vertical rod brackets is semicircular, the other sides of the vertical rod brackets are connected with a bracket connecting body by the L-shaped equilateral steel angles, the vertical rod brackets are made from square pipes or circuit pipes, the transverse support pedal plates are made from plum blossom pipes, and the safety fence is made from flat iron. The engineering crawling ladder has the advantages of being adjustable in height as required, good in firmness, safe, reliable, and detachable.
Description
Technical field:
The utility model relates to a kind of cat ladder, particularly a kind of engineering cat ladder.
Background technology:
At present, used ladder in the existing construction, mostly be the cat ladder of non-removable regular length or be collapsible cat ladder, this cat ladder floor space is bigger, less stable when there is the gradient in ground, need be stable by just can make it by external force, and the height of this ladder is non-extensible, and significant limitation is arranged in use.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, provides a kind of and can regulate height automatically, and stationarity is good, dismountable engineering cat ladder.
The purpose of this utility model is achieved through the following technical solutions: a kind of engineering cat ladder, comprise the vertical rod support that a plurality of one-tenth two row are provided with, safety fence and a plurality of stull foot rest, and a plurality of stull foot rests laterally are connected between the two row vertical rod supports uniformly, two symmetries and place the lower end of the vertical rod support of lowermost end to be respectively equipped with piston therein, piston fixes on the ground by L type equal leg angle, safety fence distributes around a plurality of vertical rod support one side semicircular in shape shapes, vertical rod support opposite side is connected with the support connector by a plurality of L type unequal angles, vertical rod support material is square tube or pipe, stull foot rest material is the plum blossom pipe, and the safety fence material is a band steel.
The utility model compared with prior art has following characteristics:
Its compact conformation, ingenious, the function practicality, can carry out voltage-withstand test according to the requirement of unlike material, saved manual testing's link, so just avoided because the security incident that misoperation produces, can improve testing efficiency, reduced testing cost, only need install at the scene, time saving and energy saving.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the front view of Fig. 1;
Number in the figure: 1-vertical rod support, 2-stull foot rest, 3-safety fence, 4-piston, 5-L type equal leg angle, 6-L type unequal angle, 7-support connector.
The specific embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
As Fig. 1, Fig. 2 shows a kind of embodiment of the utility model engineering cat ladder: comprise the vertical rod support 1 that a plurality of one-tenth two row are provided with, safety fence 3 and a plurality of stull foot rest 2, and a plurality of stull foot rests 2 laterally are connected between the two row vertical rod supports 1 uniformly, two symmetries and place the lower end of the vertical rod support 1 of lowermost end to be respectively equipped with piston 4 therein, piston 4 fixes on the ground by L type equal leg angle 5, safety fence 3 distributes around a plurality of vertical rod support 1 one side semicircular in shape shapes, vertical rod support 1 opposite side is connected with support connector 7 by a plurality of L type unequal angles 6, vertical rod support 1 material is square tube or pipe, stull foot rest 2 materials are the plum blossom pipe, safety fence 3 materials are band steel, cat ladder length can be provided with voluntarily according to engineering is required, and the installation and removal process is convenient, stationarity is strong, and is safe and reliable.
