Description
Technical field
The invention belongs to the electrical equipment field, particularly a kind of insulating bar.
Background technology
In the power industry outdoor study, often use the device of removing foreign matter on the cable, the characteristics of these instruments all are to be operated in the face of the high-altitude device by the staff with standing in.On removing cable during foreign matter, get an electric shock for fear of the staff and normally to adopt an end that the insulating bar of working head is installed, because the height of cable is higher, the corresponding insulating bar that just need to grow, during operation, insulating bar is oversize, and is inconvenient to carry out of doors.
In order to solve owing to the long problem that is not easy to carry of insulating bar length, people are segmented into several insulating bar sections with insulating bar, when not using, the insulating bar sections is bundled, in use, connect one by one the insulating bar sections, make the insulating bar length that connects reach work requirements, adopt this mode, insulating bar is convenient for carrying, also so that insulating bar can be competent at the differing heights cable maintenance.The insulating bar sections is generally about 2 meters at present, in use, adopt between the insulating bar sections and be threaded, employing is threaded, when assembling and fractionation insulating bar, owing to need to the insulating bar sections be carried out multiple rotary, can or remove the splicing of insulating bar sections, so normally need a plurality of staff's cooperations just can finish, and need the long time.
For the difficulty that solves above-mentioned splicing and remove the insulating bar sections, Chinese utility model patent " multiplex insulating bar ", Granted publication number: CN201289795Y, a kind of multiplex insulating bar is disclosed, this insulating bar is to adopt hollow draw-bar as the insulating bar sections, wherein the external diameter of the internal diameter of a joint pull bar and its next joint pull bar cooperates, the like, a upper joint pull bar cooperation inserts in next joint pull bar hollow pipe, when not using, each saves pull bar and is retracted into successively in next joint hollow draw-bar, successively each joint pull bar is pulled out successively again during use, adopt this structure not only to save the storage area, also so that the splicing of insulating bar sections and dismounting are all very convenient.But in this structure, the diameter of insulating bar progressively reduces successively along with the increase of length, and then so that the intensity of insulating bar progressively reduces, has limited its use in the environment of higher cable.
Summary of the invention
The object of the invention is to overcome in the prior art existing owing to insulating bar is not easy to carry, with after with the insulating bar segmentation, splicing and split difficulty between each sections, and when adopting stretching structure, the deficiency of insulating bar strength decreased provides a kind of insulating bar.Insulating bar of the present invention, the intersegmental splicing of each insulating bar and easy accessibility, and the insulating bar diameter is because the length increase does not reduce, so that insulating bar has good intensity.
In order to realize the foregoing invention purpose, the invention provides following technical scheme:
A kind of insulating bar, comprise insulating bar and the working head that is installed in insulating bar one end, described insulating bar is a plurality of insulating bar sections, in described a plurality of insulating bar sections wherein one section insulating bar sections one end be equipped with pullover, the other end is equipped with nipple or pullover, all the other insulating bar sections one ends are equipped with pullover, the other end is equipped with nipple, describedly be provided with trepanning on pullover, be provided with boss on the described nipple, the external diameter of described boss matches with described trepanning internal diameter, describedly is provided with draw-in groove on pullover, be provided with projection on the described boss, the size of described projection matches with described draw-in groove.Boss on the nipple be socketed in pullover in, splice successively each insulating bar sections, the projection on the nipple is stuck in the draw-in groove, has strengthened the compactness that connects between the insulating bar sections.
Preferably, described draw-in groove is L-type.Described projection is stuck in the L-type draw-in groove, prevents from splicing good insulating bar and comes off.
Further preferably, describedly be provided with alignment pin on pullover, described alignment pin cuts off described draw-in groove, guarantees 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 can automatically reset by spring compression.
Further, described alignment pin rear end is provided with stay cord, and the described stay cord other end is provided with draw ring.By draw ring pulling alignment pin, so that convenient when assembly unit insulating bar sections.
Further, described alignment pin top is provided with the slope mouth.In splicing during insulating bar, projection is by withstanding the slope mouth directly with alignment pin jack-up, and do not need artificial pull-up alignment pin, so that the assembly unit of insulating bar sections is convenient.
Insulating bar of the present invention, insulating bar is divided into a plurality of insulating bar sections, so that insulating bar is convenient for carrying, each insulating bar sections splices successively by the pullover and nipple that is arranged on two ends, splicing and demolishing process are simple and convenient, and the insulating bar diameter does not reduce because length increases, so that insulating bar has good intensity.
Compared with prior art, beneficial effect of the present invention:
1, insulating bar is divided into a plurality of insulating bar sections, so that insulating bar is convenient for carrying.
2, each insulating bar sections splices successively by the pullover and nipple that is arranged on two ends, and splicing and demolishing process are simple and convenient.
3, the insulating bar diameter does not reduce because length increases, so that insulating bar has good intensity.
