Description
Technical field
The invention belongs to electrical equipment field, particularly a kind of insulating bar.
Background technology
In power industry outdoor study, often use the device removing foreign matter on cable, the feature of these instruments is all stand in ground by staff to operate upper installations.When removing foreign matter on cable, one end is normally adopted the insulating bar of working head to be installed, because the height of cable is higher in order to avoid staff gets an electric shock, the corresponding insulating bar that just needs are longer, out of doors during operation, insulating bar is oversize, and is inconvenient to carry.
In order to solve the problem being not easy to because insulating bar length is longer carry, insulating bar is segmented into several insulating bar sections by people, when not using, insulating bar sections is bundled, in use, connect insulating bar sections one by one, make the insulating bar length connected reach work requirements, adopt in this way, not only make insulating bar be convenient for carrying, also make insulating bar can be competent at differing heights cable maintenance.Current insulating bar sections is generally about 2 meters, in use, adopt between insulating bar sections and be threaded, employing is threaded, when assembling and split insulating bar, because needs carry out multiple rotary to insulating bar sections, by the splicing of insulating bar sections or can remove, so normally need multiple staff's cooperation just can complete, and need the longer time.
In order to solve the difficulty of above-mentioned splicing and dismounting insulating bar sections, Chinese utility model patent " multiplex insulating bar ", Authorization Notice No.: CN201289795Y, disclose a kind of multiplex insulating bar, this insulating bar adopts hollow draw-bar as insulating bar sections, the wherein internal diameter of a joint pull bar and the major diameter fit of its next joint pull bar, the like, a upper joint pull bar cooperation inserts in next joint pull bar hollow pipe, when not using, each joint pull bar is retracted in next joint hollow draw-bar successively, successively each joint pull bar is pulled out successively again during use, this structure is adopted not only to save storage area, also make the splicing of insulating bar sections and dismounting all very convenient.But in this structure, the diameter of insulating bar progressively reduces successively along with the increase of length, and then the intensity of insulating bar is progressively reduced, limit its use in the environment of higher cable.
Summary of the invention
To the object of the invention is to overcome in prior art and existing be not easy to carry due to insulating bar, with after by insulating bar segmentation, splicing and split difficulty between each sections, and when adopting stretching structure, the deficiency that insulating bar intensity reduces, provides a kind of insulating bar.Insulating bar of the present invention, the intersegmental splicing of each insulating bar and easy accessibility, and insulating bar diameter does not reduce because length increases, and makes insulating bar have good intensity.
In order to realize foregoing invention object, the invention provides following technical scheme:
A kind of insulating bar, comprise insulating bar and the working head being arranged on insulating bar one end, described insulating bar is multiple insulating bar sections, in described multiple insulating bar sections, wherein one section of insulating bar sections one end is provided with pullover, the other end is provided with nipple or pullover, all the other insulating bar sections one end are provided with pullover, the other end is provided with nipple, described pullover on be provided with trepanning, described nipple is provided with boss, external diameter and the described trepanning diameter compatible of described boss close, described pullover on be provided with draw-in groove, described boss is provided with projection, the size of described projection matches with described draw-in groove.Boss on nipple be socketed in pullover in, splice each insulating bar sections successively, the projection on nipple is stuck in draw-in groove, enhances the compactness connected between insulating bar sections.
Preferably, described draw-in groove is L-type.Described projection is stuck in L-type draw-in groove, prevents the insulating bar spliced from coming off.
Further preferably, described pullover on be provided with alignment pin, described alignment pin cuts off described draw-in groove, ensures that described projection alignment pin when L-type draw-in groove end can prop up projection.
Still more preferably, described alignment pin rear end is provided with spring.Alignment pin, by spring compression, can automatically reset.
Further, described alignment pin rear end is provided with stay cord, and the described stay cord other end is provided with draw ring.Pull alignment pin by draw ring, make when assembled insulating bar sections convenient.
Further, described alignment pin top is provided with slope mouth.When splicing insulating bar, projecting through and withstanding slope mouth directly by alignment pin jack-up, and not needing artificial pull-up alignment pin, making the assembled convenient of insulating bar sections.
Insulating bar of the present invention, insulating bar is divided into multiple insulating bar sections, insulating bar is convenient for carrying, each insulating bar sections splices with nipple successively by being arranged on the pullover of two ends, splicing and demolishing process simple and convenient, and insulating bar diameter does not reduce because length increases, and makes insulating bar have good intensity.
compared with prior art, beneficial effect of the present invention:
1, insulating bar is divided into multiple insulating bar sections, insulating bar is convenient for carrying.
2, each insulating bar sections is by being arranged on the pullover of two ends and nipple splices successively, splicing and demolishing process simple and convenient.
3, insulating bar diameter does not reduce because length increases, and makes insulating bar have good intensity.
