Abstract
The purpose of the present invention is to provide a telescopic cross arm shielding cover comprising a main body. The vertical cross section of the main body is configured in [pi]-shaped structure. A sliding cover is disposed on the right side of the main body. The length of the shielding cover can be adjusted according to required operating distance by adding the telescopic sliding cover. The shielding cover can be lengthened or shortened in order to cover an exposed cross arm electric pole. The telescopic cross arm shielding cover has simple structure and strong practicality and may easily and fast perform insulated shielding and increase a safety factor of live working and the work efficiency of workers.
Description
Technical field
The present invention relates to a kind of masking device of altitude hot-line operation, be specifically related to a kind of cross arm shielding cover of concertina type.
Background technology
For ensureing the stability of mains supply, when the job executions such as power equipment test, maintenance and transformation, mostly adopt live line working at present.In altitude hot-line operation, often need to electric pole cross-arm, cover by cross arm shielding cover.Different in size due to cross-arm electric pole, if cross arm shielding cover is long, operating personnel installs and carries inconvenience, and easily blocks and need to detect position; If cross arm shielding cover is too short, in masking process, cover not comprehensive, thereby cause existing fatal potential safety hazard in live line working process.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, a kind of concertina type cross arm shielding cover is provided, telescopic cross arm shielding cover has function that can be flexible, can adjust length along with needed operating distance.
The object of this invention is to provide a kind of concertina type cross arm shielding cover, comprise main body, the vertical section of main body is Π type structure, and described main body right side is provided with sliding closure.
Further improvement of the present invention is: described bottom part body inner side is provided with chute, and sliding closure is back and forth flexible in main body by chute.
Further improvement of the present invention is: described main body left side is provided with boss, boss upper surface is provided with opening U-shaped breach left, breach top is provided with the inserts matching with notch geometry, on inserts, have U-shaped port, main body front is provided with installing ring, and installing ring cylindrical is gear-like.
Further improvement of the present invention is: described slide unit right end top is provided with guide vane end stop.
Further improvement of the present invention is: described inserts is detachable.
Beneficial effect of the present invention: by setting up telescopic sliding closure, make mask to adjust length along with needed operating distance, can extend or shorten and cover on the cross-arm electric pole exposing.Inserts is installed, and cross arm shielding cover is applicable to pin insulator; Remove inserts, cross arm shielding cover is applicable to pillar insulator, and the design of inserts has strengthened the practicality of mask.By setting up installing ring, can use wire clamp to do rod clamping, be convenient to install.
The present invention is simple in structure, can carrying out insulation easily and fast cover, and improves the coefficient of safety of live line working, improves operating personnel's operating efficiency, and practical.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Fig. 2 is vertical view of the present invention.
Wherein: 1-main body, 2-sliding closure, 3-inserts, 4-installing ring, 5-guide vane end stop.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
As shown in Figure 1, the present embodiment provides a kind of concertina type cross arm shielding cover, comprises main body 1, and the vertical section of main body 1 is Π type structure, and described main body 1 right side is provided with sliding closure 2.Described main body 1 bottom inside is provided with chute, and sliding closure 2 is interior back and forth flexible in main body 1 by chute, strengthens the smoothness of sliding.Described main body 1 left side is provided with boss, and boss upper surface is provided with opening U-shaped breach left, and breach top is provided with the inserts 3 matching with notch geometry, has U-shaped port on inserts 3,, be convenient to the cross-arm electric pole of tape insulation.Main body 1 front is provided with installing ring 4, and installing ring 4 cylindricals are gear-like, can use wire clamp to do rod clamping, is convenient to install.Described sliding closure 2 right end tops are provided with guide vane end stop 5, avoid in the whole indentation main bodys 1 of sliding closure 2, and can be used as holding area and be convenient to push-and-pull sliding closure 2.Described inserts 3 is detachable, and inserts 3 is installed, and cross arm shielding cover is applicable to pin insulator; Remove inserts 3, cross arm shielding cover is applicable to pillar insulator.
A kind of concertina type cross arm shielding cover that the present embodiment provides, adjusts length by sliding closure 2 according to the needed operating distance of cross-arm electric pole, then covers on the cross-arm electric pole exposing; Simple in structure, can carrying out insulation easily and fast cover, improve the coefficient of safety of live line working, improve operating personnel's operating efficiency.
