The present embodiment is a kind of penetration type electric armour clamp, sees shown in Fig. 1 to Fig. 8, including 1, core pipe 2 of a pressure ring, a set of paw assembly 3 and an axial back-up ring 4.
The periphery wall of core pipe 2 is provided with the gear platform 21 of evagination and the annular groove 22 of indent, and core tube wall has been uniformly distributed circumferentially three radially-directed holes 23; In the present embodiment, each radially-directed hole extends radially through core tube wall along core pipe. Axial back-up ring is arranged in the annular groove of core pipe.
Each radially-directed hole 23 includes the guiding slide opening 231 and the anticreep slide opening 232 that axially set gradually along core pipe; Guiding slide opening is arranged on the core pipe edge away from a side of axial back-up ring, and anticreep slide opening connects with guiding slide opening; The radial cross-sectional shape in each radially-directed hole is T-shaped; Each radially-directed hole 23 forms a breach being positioned at core tube edges place; In the present embodiment, each radially-directed hole extends radially through gear platform 21 along core pipe.
Paw assembly includes three paws 5; Each paw is provided with pressing plate portion 51, along the guide runner portion 52 that core pipe radially extends and the driver plate portion 53 that is arranged in guide runner portion; The driver plate portion of each paw is provided in the flange axially projecting along core pipe in each guide runner portion, and the outboard end of this flange is provided with chisel teeth 54.
Each pressing plate portion is arranged in core pipe tube chamber, and core tube wall is stretched out in the outer end in the guide runner portion of each paw, and each driver plate portion is positioned at outside core tube wall; Each guide runner portion 52 includes guide part 521 and anti-delinking part 522, and guide part is arranged in the guiding slide opening in a corresponding radially-directed hole, and anti-delinking part is arranged in the anticreep slide opening in a corresponding radially-directed hole; The radial cross-sectional shape of guide part and anti-delinking part is adaptive with radially-directed hole T-shaped. Each paw is under the spacing of radially-directed hole and guide effect, along core caliber to reciprocatingly sliding; The inwall in each pressing plate portion is provided with arcuate groove 55, and the arcuate groove of three paws encloses the formation one clamp hole 61 for clamping connection electric power cable.
Pressure ring 1 rotates and is arranged on the periphery wall of core pipe, and at gear platform with axially between back-up ring; The internal perisporium of pressure ring is the smooth inner wall adjacent with the slip of core pipe periphery wall; The periphery wall of pressure ring is provided with multiple binding groove 11;In the present embodiment, a side of pressure ring and axial back-up ring slide adjacent, and another side of pressure ring and the guide runner portion of each paw slide adjacent; The side that pressure ring and each paw guide runner portion adjoin is provided with three helicla flutes 12; In the present embodiment, each helicla flute includes the anticreep district 121 that connects with pressure ring vestibule 13 and the accommodating area 122 away from pressure ring vestibule; The diapire in anticreep district is provided with multiple wedge shape anticreep tooth 123, and the chisel teeth of each wedge shape anticreep tooth and paw is adaptive; Accommodating area is smooth chute; The present embodiment, when operation, adopts the binding groove that hook type spanner catches on pressure ring to twist pressure ring.
The driver plate portion of each paw is arranged in a corresponding helicla flute; Each helicla flute rotates along with pressure ring so that a corresponding driver plate portion is from being positioned at accommodating area to being positioned at anticreep district, namely this driver plate portion is produced squeezing action; Pressure ring synchronizes to drive three paws by three helicla flutes so that each pressing plate portion is close to each other towards core tube hub, thus clamping is arranged in the electric power cable in clamp hole.
When the chisel teeth in each pressing plate portion is clamped on the wedge shape anticreep tooth in corresponding anticreep district, wedge shape anticreep tooth prevents pressure ring from reversing, so that the present embodiment has good anti-loosening effect.
The present embodiment, in order to connect electricity from insulating power cable, is also provided with multiple puncture 62 in each arcuate groove; Specifically, respectively puncture along core pipe radially protruding. The existence punctured, it is possible to without insulating power cable is carried out peeling process, can effectively connect electricity. In concrete practice, if what to clamp is bare wire, then can be not provided with puncturing.
In the present embodiment, each paw is the integral piece made by casting forming, and each puncture is made when casting forming; In concrete practice, puncture may be used without alternate manner and makes; In each arcuate groove, be such as provided with multiple installation draw-in groove, then install in draw-in groove be inlaid in corresponding one by the die-cut puncture sheet made; Puncturing sheet include installation portion and sting blade, installation portion is inlaid in installation draw-in groove, and thorn blade then exposes installation draw-in groove and forms puncture. The benefit of this structure is to puncture sheet the material different with paw can be adopted to make, and especially selects and treats that same material used by clamp cable is made, being conducive to obtaining preferably electric property.
The present embodiment is by being arranged on cable clamping at the longitudinal center line place of electric armour clamp, and its gravity centre distribution is relatively reasonable, when on the overhead power line of high-altitude, is conducive to alleviating vibration; Additionally, each paw is positioned by the present embodiment by having the slope groove of wedge shape anticreep tooth, it is possible to play the technique effect preventing from falling back, and compares with by traditional bolt assembly clamping electric power cable, in anti-loosening effect particularly excellent, be effectively ensured the reliability of long-term work.
