Technical field
The utility model relates to a kind of improvement of spanner, specifically the unidirectional handle spanner that turns of a kind of charged dismounting arrester stud bolt.Be mainly used in the dismounting of 10kV leakage conductor stud bolt.
Background technology
At present, in order to improve the power supply reliability of 10kV circuit, the 10kV circuit that is subject to damage to crops caused by thunder at some has all installed leakage conductor, the power outage bringing to reduce the natural calamities such as thunderbolt additional.But, when after the faults such as 10kV leakage conductor punctures, in order to reduce frequency of power cut, need the arrester of charged timely replacing fault, operating personnel is in the time carrying out 10kV charged for replacement arrester, after need covering completely the electrical body such as high pressure downlead, cross-arm of pile crown on arrester and earth potential object, could start arrester stud bolt to dismantle.For the dismounting of arrester stud bolt, current method is: stood on hoistable platform by operating personnel, higher than the installation site of arrester stud bolt, adopt common spanner, have on insulating glove and dismantle, the deficiency of this spanner is: the one, because handle is shorter, need near arrester stud bolt, so just simultaneously near charged position, so increased the unsafe factor of operating personnel in operation process; The 2nd, in Renewal process, because arrester exists fault, be likely short-circuited at any time, in the time of operation, operating personnel has also increased task difficulty owing to wearing insulating glove.Known by retrieving, have not yet to see remote, by unidirectionally turning the rotation of handle, with moving sleeve one-directional rotation, realize the report of the spanner of dismounting arrester stud bolt.
Summary of the invention
It is a kind of simple in structure, safe and convenient to use that the purpose of this utility model is to provide, away from charged position in the situation that, can be by unidirectionally turning the rotation of handle, with moving sleeve one-directional rotation, realize the unidirectional handle spanner that turns of charged dismounting arrester stud bolt of the charged dismounting of 10kV leakage conductor stud bolt.
In order to reach above object, the technical scheme that the utility model adopts is: the unidirectional handle spanner that turns of this charged dismounting arrester stud bolt, formed by telescopic insulating bar and arrester stud bolt sleeve, described telescopic insulating bar is socketed to form by 2-3 joint insulating sleeves, and fix its collapsing length by insulation set bolt, maximum extension length is 2m; The inwall of described arrester stud bolt sleeve and the outer wall of arrester stud bolt match; It is characterized in that: on the upper end sidewall of described arrester stud bolt sleeve, in vertical welding, " L " shape is turned the horizontal termination of handle, turn the sheathed one-directional rotation cover in perpendicular upper end of handle " L " shape, the front end vertical welding of telescopic insulating bar is fixed on the lateral wall middle part of one-directional rotation cover.
The utility model is also implemented by following measure: described one-directional rotation cover, comprise inner side ring set, outside ring set and spin, inner side ring set is fixedly set in " L " shape and turns the perpendicular upper end of handle, on the perisporium of inner side ring set, be provided with circlewise, the semispherical indentations of equidistant arrangement, on the inwall of outer ring cover, be provided with circlewise, equidistant arrangement, wedge be to consistent wedge-shaped slot, outside ring set is enclosed within on the ring set of inner side; In described wedge-shaped slot, be equipped with spin, the diameter of spin is consistent with the diameter of the semispherical indentations on the ring set of inner side, and mutually corresponding.
The beneficial effects of the utility model are: the unidirectional handle spanner that turns of this charged dismounting arrester stud bolt, simple in structure, safe and convenient to use, owing to having adopted telescopic insulating bar, so can be away from charged position in the situation that, by arrester stud bolt jacket casing on arrester stud bolt; Owing to realizing the one-directional rotation of arrester stud bolt sleeve by one-directional rotation cover, so as long as the telescopic insulating bar of continuous push-and-pull can drive arrester stud bolt sleeve one-directional rotation, realize the charged dismounting of 10kV leakage conductor stud bolt.Improve processing safety, reduced labour intensity, reduced staff's operating time, also reduced power off time.Can be widely used in the charged dismounting of 10kV leakage conductor stud bolt.
Brief description of the drawings
Fig. 1 is structure schematic side view of the present utility model.
Fig. 2 is that structure of the present utility model is analysed and observe enlarged diagram along A-A.
In figure: 1, telescopic insulating bar; 2, arrester stud bolt sleeve; 3, insulation set bolt; 4, " L " shape is turned handle; 5, one-directional rotation cover; 6, inner side ring set; 7, outside ring set; 8, spin; 9, semispherical indentations; 10, wedge-shaped slot.
Detailed description of the invention
Make the utility model with reference to Fig. 1, Fig. 2.The unidirectional handle spanner that turns of this charged dismounting arrester stud bolt, formed by telescopic insulating bar 1 and arrester stud bolt sleeve 2, described telescopic insulating bar 1 is socketed to form by 2-3 joint insulating sleeves, and fix its collapsing length by insulation set bolt 3, maximum extension length is 2m, to adapt to the length of operating personnel from 10kV leakage conductor stud bolt distance; The inwall of described arrester stud bolt sleeve 2 and the outer wall of arrester stud bolt match, so that arrester stud bolt sleeve 2 can not skid in the time rotating and between the outer wall of arrester stud bolt; It is characterized in that: on the upper end sidewall of described arrester stud bolt sleeve 2, in vertical welding, " L " shape is turned the horizontal termination of handle 4, turn the sheathed one-directional rotation cover 5 in perpendicular upper end of handle 4 " L " shape, the front end vertical welding of telescopic insulating bar 1 is fixed on the lateral wall middle part of one-directional rotation cover 5, in the time that the original position of one-directional rotation cover 5 is in the front, right side of arrester stud bolt sleeve 2, can makes " L " shape turn handle 4 by the promotion of telescopic insulating bar 1 and rotate counterclockwise along the axis of arrester stud bolt sleeve 2; In the time that one-directional rotation cover 5 forwards the rear, left side of arrester stud bolt sleeve 2 to, can make " L " shape turn handle 4 by pulling of telescopic insulating bar 1 rotates counterclockwise along the axis of arrester stud bolt sleeve 2, continuous like this push-and-pull, can make continuous the rotating by counter clockwise direction of arrester stud bolt sleeve 2, thereby unload arrester stud bolt.
As improvement of the present utility model: described one-directional rotation cover 5, comprise inner side ring set 6, outside ring set 7 and spin 8, inner side ring set 6 is fixedly set in " L " shape and turns the perpendicular upper end of handle 4, on the perisporium of inner side ring set 6, be provided with circlewise, the semispherical indentations 9 of equidistant arrangement, on the inwall of outer ring cover 7, be provided with circlewise, equidistant arrangement, wedge be to consistent wedge-shaped slot 10, outside ring set 7 is enclosed within on the ring set 6 of inner side; In described wedge-shaped slot 10, be equipped with spin 8, the diameter of spin 8 is consistent with the diameter of the semispherical indentations 9 on inner side ring set 6, and mutually corresponding; When by promote or pull telescopic insulating bar 1 make outside ring set 7 along the wedge of wedge-shaped slot 10 when rotating backward, spin 8 enters in semispherical indentations 9, rotates thereby stir inner side ring set 6, turns handle 4 thereby can promote " L " shape; When the wedge along wedge-shaped slot 10 is during to rotating in same direction, spin 8 skids off semispherical indentations 9, enters in the large space of wedge-shaped slot 10, no longer stirs inner side ring set 6, and inner side ring set 6 stops, and turns handle 4 and rotates thereby can not promote " L " shape.
