Utility model content
For solving the problems of the technologies described above, the utility model aims to provide the relieving attachment of a kind of ultra-high-tension power transmission line conductor spacer, utilizes this instrument to dismantle easily conductor spacer, has advantages of that time saving and energy saving efficiency is high.
For achieving the above object, the utility model has adopted following technical scheme, the relieving attachment of this ultra-high-tension power transmission line conductor spacer, and its structural feature is: have a rhizoid bar, a rotating cylinder is spinning on the top of described screw mandrel; In the bottom of described screw mandrel, be fixedly connected with a power post, the middle part of this power post has a waist through hole, is provided with a push rod that can freely overturn in described waist through hole.
As preferably, described rotating cylinder is nested with on a gland, this gland with described rotating cylinder for being flexibly connected.
As preferably, on the outer wall of described gland and the inwall of described rotating cylinder, be respectively equipped with a spill annular groove, closing in groove of described two spill annular grooves, be provided with ball, by ball, described gland and rotating cylinder are flexibly connected into whole.
As preferably, described push rod is arranged in described waist through hole by a circular bearing pin.
As preferably, the end face semicircular in shape of the free-end of described power post.
Beneficial effect: than existing, the utility model yet there are no open report and use, it utilizes the design feature of existing wire clamp of conductor spacer, during use, power post is extended through to the groove of wire clamp lower clamping piece, then push rod overturns, make on its diapire that withstands on lower clamping piece, play again rotating cylinder, make the bottom surface of rotating cylinder be pressed on the end face of upper clamping piece through hole, locking folder from top to bottom, thereby reach the object of loose pivot pin, now can extract easily pivot pin, make folder from top to bottom depart from wire and the end of dismantling wire clamp, have advantages of that time saving and energy saving efficiency is high.
Below by accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the sectional perspective structural representation of conductor spacer.
Fig. 2 is the main view plane structural representation of an embodiment of the utility model.
Fig. 3 is the structure for amplifying schematic diagram of A portion in Fig. 2.
In figure: wire clamp 1, line hole 2, lower clamping piece 21, groove 22, upper clamping piece 3, through hole 31, pivot pin 4, bearing pin 5, clamping piece 6.Rotating cylinder 10, handle 20, rotation set 30, gland 40, screw mandrel 50, power post 60, push rod 70.
Embodiment
Referring to Fig. 1, Fig. 2.The relieving attachment of this ultra-high-tension power transmission line conductor spacer, its structural feature is: there is a rhizoid bar 50, the rotating cylinder 10 that spinning on the top of described screw mandrel 50, this rotating cylinder 10 by lever handle 20 control backspins or on revolve.In the bottom of described screw mandrel 10, be fixedly connected with a power post 60, the middle part of this power post 60 has a waist through hole, is provided with a push rod that can freely overturn 70 in described waist through hole.Power post 60 and screw mandrel 50 are single piece.
During as preferred concrete enforcement, described rotating cylinder 10 is nested with the periphery at a gland 40, this gland 40 with rotating cylinder 10 for being flexibly connected, that is: on the inwall of the outer wall of gland 40 and rotating cylinder 10, a spill annular groove is set respectively, closing in groove of described two spill annular grooves, put into ball, by ball, gland 40 and rotating cylinder 10 are flexibly connected into whole.The outer wall of rotating cylinder 10 to described in close groove and offer a through hole, ball is put into through this through hole, seals this through hole after putting into again, and realizes and connecting.The object that described gland 40 is set is: when rotating cylinder 10 backspin, push gland 40 descending, first the lower surface of gland 40 is offseted with the end face of upper clamping piece 3, due to gland 40, can only to make straight line descending, therefore, when the lower surface of gland and the end face of upper clamping piece 3 offset, can not produce spin friction, thereby guarantee that the end face of upper clamping piece 3 is not worn.
During use, operating personnel first see Fig. 1 by power post 60 via through holes 31() through groove 22, and make push rod 70 be positioned at the below of groove 22, now, rout up push rod 70 and make it horizontal on the bottom surface of groove 22.Then, operating grip 20 make rotating cylinder 10 and gland 40 descending, until the bottom surface of gland 40 is pressed on (the bottom surface external diameter of gland 40 is greater than the aperture of through hole 31) on through hole 31, at push rod 70 and gland 40 in opposite directions under the effect of power, eliminate the pressure of upper clamping piece 3 and 21 pairs of pivot pins 4 of lower clamping piece, make pivot pin 4 in relaxed state, now can extract easily pivot pin 4, convolution rotating cylinder 10, can unload an end of wire clamp of conductor spacer, so complete the dismounting of four ends of wire clamp, finally realize the object that unloads conductor spacer.
If do not establish gland 40, by the bottom surface of rotating cylinder 10, completed the same function of gland 40, still, because rotating cylinder 10 is backspin bodies, upper clamping piece 3 through holes 31 roof around will be damaged in its bottom surface.
Above-described embodiment is only for explaining utility model thinking of the present utility model, and any simple deformation structure that is subject to its inspiration and makes, all should include protection range of the present utility model in.
