Abstract
The utility model discloses a cat ladder antiskid lock, including " II " shape curb girder fixed frame, be equipped with the tight mechanism in bolt top on " II " shape curb girder fixed frame, still be fixed with cat ladder limiting clamping plate on " II " shape curb girder fixed frame, cat ladder limiting clamping plate can take on leaning against the object, prevents the cat ladder gliding. The utility model discloses the problem of must the special messenger in the time of can effectively solving the cat ladder and use holding up.
Description
Technical field
The utility model relates to ladder technical field.
Background technology
In substation equipment maintenance and repair working site, the utilization rate of cat ladder is the highest, and the work in nearly all switch, disconnecting link, the little device framework of transformer station four (potential transformer, current transformer, arrester and coupling capacitor) all can use cat ladder.
In the use procedure of cat ladder, there is the risk that slips, for avoiding risk, ensureing ascending stair operator personal safety, current when using cat ladder, often need to arrange special messenger's staircase; If but staircase people inadvertent, ladder still likely can slip, thus causes ascending stair operator to come to harm, so existing cat ladder using method exists, potential safety hazard is large, the problem of waste of human resource.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provides a kind of cat ladder antiskid lock, must special messenger's problem of holding up for solve when cat ladder uses, have simple and reasonable for structure, quality is light, moulding is little, easy to operate, saving manpower, the feature of safety.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of cat ladder antiskid lock, comprise " П " shape curb girder fixed frame, " П " shape curb girder fixed frame is provided with bolt jacking mechanism, " П " shape curb girder fixed frame is also fixed with the spacing clamp of cat ladder, the spacing clamp of cat ladder can ride over and lean against on object, prevents cat ladder from gliding.
As to further restriction of the present utility model, preferred version is, described " П " shape curb girder fixed frame one side is provided with screwed hole, and bolt and this screwed hole coordinate, and the outer end of bolt is provided with turning handle, is rotationally connected between the inner end of bolt and pressing plate.
The inner end of described bolt also nonrotationally can be connected for fixed with between pressing plate, or does not arrange pressing plate.
As to further restriction of the present utility model, preferred version is, the spacing clamp of described cat ladder is that inclined at acute angles tilts to be fixedly connected with " П " shape curb girder fixed frame one side.
Or the spacing clamp of described cat ladder is that inclined at acute angles is fixedly connected with " П " shape curb girder fixed frame bottom surface.
Such scheme is adopted to bring following beneficial effect: first, cat ladder curb girder and cat ladder are locked and are fixed together by " П " shape curb girder fixed frame and bolt jacking mechanism jointly, the spacing clamp of cat ladder rides over and leans against on object, indirectly cat ladder curb girder is fixed together with leaning against object, operator is when ascending stair, and cat ladder lock just instead of the role of staircase people, serves the effect of strong fix cat ladder, like this under the prerequisite of personal safety ensureing operator, save manpower; In addition connect between its each parts rationally, structure is simple, quality is light, moulding is little, easy to operate, therefore has very large practicality.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, Fig. 4, a kind of cat ladder antiskid lock, comprise " П " shape curb girder fixed frame 1, " П " shape curb girder fixed frame 1 is provided with bolt jacking mechanism 2, " П " shape curb girder fixed frame 1 is also fixed with the spacing clamp 3 of cat ladder, the spacing clamp 3 of cat ladder can ride over and lean against on object, prevents cat ladder from gliding.
Described bolt jacking mechanism 2 also comprises, and " П " shape curb girder fixed frame 1 one side is provided with screwed hole 4, and bolt 5 and this screwed hole 4 coordinate, and the outer end of bolt 5 is provided with turning handle 6, is rotationally connected between the inner end of bolt 5 and pressing plate 7.
The spacing clamp 3 of described cat ladder is that inclined at acute angles is fixedly connected with " П " shape curb girder fixed frame 1 one side.
With reference to Fig. 2, Fig. 3, cat ladder antiskid lock respectively arranges 1 on 2 " П " shape curb girders, and concrete use procedure is as follows: first, and rotary motion handle 6 is with dynamic pressure plate 7 to move up, and is enclosed within by curb girder fixed frame 1 on cat ladder curb girder 8; Subsequently, rotary motion handle 6, band dynamic pressure plate 7 moves down, and makes cat ladder curb girder 8 closely firmly be enclosed within curb girder fixed frame 1, finally, is stuck on supporter cross bar 9 by spacing for cat ladder clamp 3.Utilize cat ladder antiskid lock to achieve strong fix between cat ladder and supporter like this, special messenger's staircase need not be arranged, greatly save manpower.
