Abstract
The utility model discloses a combined ladder. The combined ladder comprises a main ladder frame and a sliding ladder frame, wherein a slide way is arranged on the inner side of the main ladder frame; the sliding ladder frame is arranged on the slide way; a fastening plate which is movably connected with a transverse beam of the main ladder frame is arranged at the bottom of the sliding ladder frame. With the combined ladder, the sliding ladder frame can slide on the slide way of the main ladder frame up and down; when the sliding frame slides to a pre-set position, the fastening plate on the sliding ladder frame is fixed with the transverse beam of the main ladder frame to realize adjustable height of the combined ladder.
Description
Technical field
The utility model relates to a kind of high-voltage hot-line work instrument, more particularly, relates to a kind of combination ladder.
Background technology
In power transmission and distribution technical field, insulating ladder is the indispensable instrument of altitude hot-line operation.Existing insulating ladder is all generally to rely on or connect on the line to use, highly limited; Higher when the construction of line, while exceeding the height of insulating ladder, insulating ladder can not be used.
Utility model content
The utility model embodiment provides a kind of combination ladder, to address the above problem.
A kind of novel combination ladder that the utility model provides, comprising:
Main ladder support and slip ladder;
The inner side of described main ladder support is provided with slideway;
Described side-rolling ladder frame is arranged on described slideway;
The bottom of described slip ladder is provided with the plate that links closely being flexibly connected with described main ladder support crossbeam.
Above-mentioned combination ladder, preferred, described slideway comprises many group slide assemblies;
Described slide assemblies comprise the first chute and the second chute;
In described the first chute and described the second chute, be respectively arranged with pulley;
On the symmetrical both sides ladder that is separately positioned on described main ladder support of described the first chute and described the second chute.
From technique scheme, can find out, in the utility model, slip ladder can slide up and down on the slideway of main ladder support, when slip ladder slides into precalculated position, can fix by the crossbeam of link closely plate and main ladder support on slip ladder, realized the Height Adjustable of combination ladder.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, the accompanying drawing the following describes is only some embodiment that record in the utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation of a kind of combination ladder that Fig. 1 provides for the utility model;
The structural representation of a kind of combination ladder middle slideway that Fig. 2 provides for the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to protection domain of the present utility model.
The structural representation of a kind of combination ladder that the utility model embodiment provides as shown in Figure 1, comprising: main ladder support 101 and slip ladder 106;
The inner side of described main ladder support is provided with slideway 105;
Described slip ladder 106 is arranged on described slideway 105;
The bottom of described slip ladder 106 is provided with the plate 103 that links closely being flexibly connected with described main ladder support crossbeam 102.
Described slideway 105 comprises many group slide assemblies;
Described slide assemblies comprise the first chute 107 and the second chute 109;
In described the first chute 107 and described the second chute 109, be respectively arranged with pulley 108;
On described the first chute 107 and the symmetrical both sides ladder that is separately positioned on described main ladder support 101 of described the second chute 109.
By above technical scheme, can show that the combination ladder that the embodiment of the present application provides is comprised of main ladder support 101 and slip ladder 106; On the both sides ladder of described main ladder support, be provided with slideway 105, described slideway 105 comprises many group slide assemblies; Described slide assemblies as shown in fig. 1, are arranged between the ladder of main ladder support both sides, and between upper and lower two crossbeams of main ladder support 105.
As shown in Figure 2, show the structural representation of the utility model embodiment slide assemblies, the enterprising line slip of slideway that slip ladder 106 can form at described a plurality of slide assemblies.
In the combination ladder that the utility model embodiment provides, in the bottom of slip ladder 106, be provided with the plate 103 that links closely; The described plate 103 that links closely fixes with the crossbeam of the bottom of described slip ladder 106.When slip ladder 106 slides into precalculated position, by linking closely, plate 103 snaps onto on the crossbeam of main ladder support 101.
The utility model can according to actual needs, arbitrarily regulate the height of extension ladder by the combination of any crossbeam on link closely plate and main ladder support on slip ladder.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
