Background technology:
Along with the large-scale popularization of cross-inked polyethylene power cable is applied, cable operation at the scene is not easily displayed gradually by the operation link of manual control, by acknowledged difficult point it is: the outer semiconducting layer of crosslinked cable cable core and the stripping of insulating barrier, this is also the core of quality control in power cable installation and repairing.By operating procedure standard-required, this stripping dimension precision requirement is significantly high, simultaneously because crosslinked cable installation and repairing complex process, therefore, gets hold of standardized installation and repairing technique, is our target of pursuing.The fact also demonstrates that, causes the reason that power cable has an accident, and the accident having 1/3rd is owing to installation and repairing quality does not reach the hidden danger that technological standards is buried.The stripping and cutting tool of current existing cross-linked power cable conductive layer and insulating barrier has multiple, such as the special stripping and cutting tool of cable from the U.S., Italy's import, but, these some being not acclimatized of import specific purpose tool, do not meet China's national situation, certain structures is complicated, relatively costly, complex process and need many people coordinate, inefficiency.
Summary of the invention:
The technical problem to be solved is: overcome the deficiencies in the prior art, it is provided that a kind of reasonable in design, simple in construction, the cross-linked power cable semi-conducting layer peeling tool outside that stripping is effective and work efficiency is high.
The technical scheme is that a kind of cross-linked power cable semi-conducting layer peeling tool outside, containing framework ring, guide cover and end cap, three is fixed together by connecting bolt, and, described framework ring is clamped between described guide cover and end cap, described framework ring is evenly arranged with three dynamic cutteves, it is provided with stage clip between described dynamic cutter and described framework ring, described framework ring is set with a retaining ring, the inner ring surface of described retaining ring is evenly arranged with three arc positioning grooves, the bottom surface of described arc positioning groove is made up of the location cambered surface at two ends and middle connection cambered surface, the radius of curvature of two described location cambered surfaces is different, the outer end of three described dynamic cutteves is all stretched out described framework ring and lays respectively in three described arc positioning grooves.
Described dynamic cutter is made up of knife rest and cutter head, described knife rest is provided with bar hole, arranging a connecting pin in described bar hole, the two ends of described connecting pin are fixed on described framework ring, are provided with back-moving spring between the bottom surface, outer end of described connecting pin and described bar hole；Described cutter head is arranged on the inner of described knife rest.Described cutter head is that rib more than three is cone-shaped.Radially uniform three through holes on described framework ring, three described dynamic cutteves are separately positioned in three described through holes.Being evenly arranged with three arcuate grooves on the outer ring surface of described retaining ring, three described arcuate grooves and three described arc positioning groove interleaved are arranged；The outer end of described dynamic cutter is provided with gland.
The invention has the beneficial effects as follows:
1, the present invention controls the flexible of dynamic cutter by retaining ring, thus accurately cutting crosslinked cable, ring cutting and rip cutting are coordinated to carry out, convenient and swift.
2, arranging arc positioning groove in retaining ring of the present invention, the inner surface of arc positioning groove is positioned cambered surface by two and a connection cambered surface is constituted, and connects cambered surface and realizes the compression of dynamic cutter and overhanging, the position of the fixing dynamic cutter of location cambered surface realization, it is ensured that cutting accuracy.
3, three arc positioning groove structures of retaining ring inner ring surface of the present invention are identical, it is ensured that the motion synchronicity of three dynamic cutteves and feeding accuracy, and firmly uniformly, efficiency is high.
4, three arcuate grooves on the outer ring surface of retaining ring of the present invention and three arc positioning groove interleaved on inner ring surface are arranged, it is simple to operator holds rotation.
5, the present invention is reasonable in design, simple in construction, stripping is effective and work efficiency is high, and it is applied widely, it is easy to promotion and implementation, has good economic benefit.

Detailed description of the invention:
Embodiment: referring in Fig. 1-Fig. 4, figure, 1-guide cover, 2-moves cutter, 3-gland, 4-framework ring, 5-connecting pin, 6-back-moving spring, 7-end cap, 8-retaining ring, 9-arc positioning groove, 10-connecting bolt, 11-cross-linked power cable.
Cross-linked power cable semi-conducting layer peeling tool outside contains framework ring 4, guide cover 1 and end cap 7, three is fixed together by connecting bolt 10, and, framework ring 4 is clamped between guide cover 1 and end cap 7, wherein: radially uniform three through holes on framework ring 4, each through hole is all set with a dynamic cutter 2, dynamic cutter 2 is made up of knife rest and cutter head, knife rest is provided with bar hole, bar hole arranges a connecting pin 5, the two ends of connecting pin 5 are fixed on the hole wall of through hole, are provided with back-moving spring 6 between the bottom surface, outer end of connecting pin 5 and bar hole；Cutter head is arranged on the inner of knife rest.Framework ring 4 is set with a retaining ring 8, the inner ring surface of retaining ring 8 is evenly arranged with three arc positioning grooves 9, the bottom surface of arc positioning groove 9 is made up of the location cambered surface at two ends and middle connection cambered surface, the radius of curvature of two location cambered surfaces is different, and the outer end of three dynamic cutteves 2 is all stretched out framework ring 4 and lays respectively in three arc positioning grooves 9.
Cutter head is that rib more than three is cone-shaped, naturally it is also possible to for other shapes, determines as required, does not describe in detail one by one.It addition, be evenly arranged with three arcuate grooves on the outer ring surface of retaining ring 8, three arcuate grooves and three arc positioning groove 9 interleaved are arranged, it is simple to staff grips and rotates；The outer end of dynamic cutter 2 is provided with gland 3.
