Abstract
The utility model discloses a kind of multifunction insulating chain type snap ring ladder, and its structure comprises snap ring, two vertical chains and horizontal chain, and two described vertical chains be arranged in parallel, are provided with some horizontal chains between two vertical chains; Two described vertical chain tops are respectively equipped with semicircle snap ring, and described snap ring is connected with the top of vertical chain by axle.The snap ring of this snap ring ladder by spring and anti-skidding projection can with line bar close contact, prevent that climbing personnel snap ring ladder in climbing process from gliding, and guaranteed staff's safety.And snap ring the line bar that can adapt to different-diameter is set, applicability is strong, uses, the feature of easy-to-operate.
Description
Technical field
The utility model relates to a kind of handling implement, specifically a kind of multifunction insulating chain type snap ring ladder.
Background technology
In the overhaul and operation maintenance of electric distribution network, along with the use of city line without stay rod, avoided line bar bracing wire impact, but a large amount of uses without stay rod, especially the special bar type in some special locations, distribution fortune inspection personnel maintenance, safeguard equipment on bar, need to step on bar, because of bar footpath thicker, cannot use and pedal high climbers, to stepping on bar personnel, bring inconvenience, what have have to adopt by means of high altitude vehicle or traditional ladder, but traditional ladder because of bar footpath thicker, again circular, ladder easily skids, high altitude vehicle also exists that because of On-the-spot factor, limit can not be close, all reasons are brought the inconvenience such as expensive and construction safety hidden danger.At present, the solution also not had.
Utility model content
The purpose of this utility model is to provide a kind of multifunction insulating chain type snap ring ladder, the snap ring of this snap ring ladder by spring and anti-skidding projection can with line bar close contact, prevent that climbing personnel snap ring ladder in climbing process from gliding, and guaranteed staff's safety.And snap ring the line bar that can adapt to different-diameter is set, applicability is strong, uses, the feature of easy-to-operate.
The technical scheme in the invention for solving the technical problem is: a kind of multifunction insulating chain type snap ring ladder, its structure comprises snap ring, two vertical chains and horizontal chain, two described vertical chains be arranged in parallel, are provided with some horizontal chains between two vertical chains; Two described vertical chain tops are respectively equipped with semicircle snap ring, and described snap ring is connected with the top of vertical chain by axle.
Further, between the inner side of two snap rings, be provided with spring, described snap ring inner side edge is provided with several anti-skidding projections.
Further, the inner side edge radian of described snap ring is identical with the outside radian of electric pole.
The beneficial effects of the utility model are:
1, because the top at the vertical chain of snap ring ladder is provided with arc snap ring, drive snap ring to be upturned downwards, thereby hold line bar tightly when ladder is exerted oneself, staff can climb, and than using, pedal button is convenient, safety, time saving and energy saving.
2, owing to being provided with spring between the inner side of snap ring, when snap ring is stuck on line bar, can make snap ring and line bar close contact, prevent that snap ring from gliding; Arranging of spring can also make snap ring adapt to the different line bar of diameter, strengthened practicality.
3, because the inner side edge at snap ring is provided with several anti-skidding projections, increased the friction with line bar outside, strengthened the steadiness that snap ring contacts with line bar, can better guarantee the personnel's of climbing safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is use state diagram of the present utility model;
In figure: 1 snap ring, 2 vertical chains, 3 horizontal chains, 4 axles, 5 springs, 6 anti-skidding projections, 7 line bars.
The specific embodiment
With reference to Figure of description, a kind of multifunction insulating chain type snap ring ladder of the present utility model is described in detail below.
As shown in Figure 1 and Figure 2, a kind of multifunction insulating chain type snap ring ladder of the present utility model, its structure comprises snap ring 1, two vertical chains 2 and horizontal chain 3, and two described vertical chains 2 be arranged in parallel, are provided with some horizontal chains 3 between two vertical chains 2; Two described vertical chain 2 tops are respectively equipped with semicircle snap ring 1, and described snap ring 1 is connected with the top of vertical chain 2 by axle 4.
Between the inner side of two snap rings 1, be provided with spring 5, it anti-skidding protruding 6, anti-skidding protruding 6 is quality of rubber materials that described snap ring 1 inner side edge is provided with several, increases friction reinforced the stability that snap ring 1 contacts with line bar 7 with line bar 7.
Pull snap ring 1, can realize the size of snap ring 1 diameter by spring 5, the line bar that is applicable to different-diameter uses, and has improved practicality.Compactness when simultaneously the tensile force of spring 2 also can guarantee that snap ring 1 is encircled with line bar 7.
As shown in Figure 3, the inner side edge radian of described snap ring 1 is identical with the outside radian of line bar, has guaranteed that the outside of snap ring 1 inner side and line bar 7 fits tightly, and increases friction, prevents from gliding.
Before ascending stair, first two snap rings 1 are pulled open by spring 5, the normal non-tension that arranges of spring coordinates snap ring application diameter at 45 centimeters, maximum tension coordinates snap ring to reach 95 centimeters, can be convenient to pull open snap ring, make snap ring 1 be clipped in line bar outside, one side of the vertical online bar of chain ladder, during ascending stair, pin is trampled on horizontal chain 3, chain ladder is exerted oneself downwards, now, the top of vertical chain 2 drives snap ring 1 motion downwards, one end down sliding that snap ring 1 is connected with vertical chain 2, drive the free end of snap ring 1 to be upturned simultaneously, two snap rings 1 are just encircled with line bar 7 more closely, strengthened the steadiness that snap ring 1 contacts with line bar 7, can better guarantee the personnel's of climbing safety.
Snap ring ladder of the present utility model snap ring by spring and anti-skidding projection can with line bar close contact, prevent that climbing personnel snap ring ladder in climbing process from gliding, and guaranteed staff's safety.And snap ring the line bar that can adapt to different-diameter is set, applicability is strong, uses, the feature of easy-to-operate.
The above, principles more of the present utility model just explain through diagrams, this manual is not in concrete structure and the scope of application described shown in the utility model will being confined to, therefore the corresponding modify being likely utilized every and equivalent, all belong to the scope of the claims that the utility model is applied for.
Except technical characterictic described in manual, all the other technical characterictics are those skilled in the art's known technology.
