A kind of cable apparatus for peeling off
Technical field
The present invention relates to the stripping off device of a kind of electric power cable the end of a thread portion insulating barrier.
Background technology
In the power construction, when wiring, need be with the insulation displacement of cable head.Cable with diameter 50-150mm is an example, and its thickness of insulating layer is 3-8mm, and the insulating barrier material generally is the material of high strength such as crosslinked polyethylene.In the past, in construction, we generally adopted electrician's knife cutting, peeled off, and operation easier is quite big, and especially in the winter time, insulating barrier hardness is very big, and cutting a end of a thread needs for a long time, and the end of a thread after the cutting is peeled off place's out-of-shape.Afterwards, we adopted electronic cutter to cut, and had alleviated the labour intensity of this work.But in when operation, still be difficult to hold the track of motion, can occur helical trajectory, feeding dark excessively/problem such as shallow.Optimal cable head is peeled off, and should be that remaining insulating barrier is regular taper surface.
Summary of the invention
The present invention is directed to above problem, provide a kind of energy easily, fast, and can make remaining insulating barrier present the cable apparatus for peeling off of regular taper surface accurately.
Technical scheme of the present invention is: comprise electronic cutter, described electronic cutter afterbody is provided with the back free bearing, and electronic cutter head is provided with preceding free bearing; It also comprises electronic cutter circulatory motion operating means, and described electronic cutter circulatory motion operating means comprises the collar, vertical rod, sliding sleeve and hand lever; Described collar external peripheral surface is provided with a circle T-slot, and described vertical rod is provided with T shape structure towards an end of T-slot, thereby vertical rod is linked to each other by T-slot with the collar, and vertical rod can be moved around the collar; The other end of described vertical rod and described back free bearing are hinged; Described sliding sleeve is hinged on the middle part of vertical rod, and described hand lever and described sliding sleeve are slidingly connected, described hand lever towards an end of electronic cutter and described before free bearing hinged.
Described collar endoporus is a bellmouth.
The described collar is a half slide structure.
The present invention is in conjunction with the characteristics of stripper wire cable end (end) portion insulating barrier, for electronic cutter provides a circulatory motion operating means, the blade that it can guarantee electronic cutter is done circulatory motion around the cable axis, and then the circumference that cuts out rule, as the remaining insulating barrier of needs is taper, can electronic cutter be set to cable in a certain anglely, have angle thereby make between blade and cable.The operator can make vertical rod take exercises around the collar by holding hand lever, moves in a circle thereby drive electronic cutter, and insulating barrier is cut.In addition, be to regulate the depth of cut, sliding sleeve and the hinged mode of vertical rod employing in addition can relative motions between hand lever and sliding sleeve, thereby when making the operator hold hand lever, can carry out the adjusting of the depth of cut.For ease of using, the inner ring surface of the collar is set to taper, and during use, cover withstands on the end face of cable, can play certain fixation.

Embodiment
The present invention comprises electronic cutter 4 as shown in Figure 1, 2, and described electronic cutter 4 afterbodys are provided with back free bearing 6, and electronic cutter 4 heads are provided with preceding free bearing 5; It also comprises electronic cutter circulatory motion operating means, and described electronic cutter circulatory motion operating means comprises the collar 11, vertical rod 7, sliding sleeve 8 and hand lever 9; The described collar 11 external peripheral surfaces are provided with a circle T-slot 10, and described vertical rod 7 is provided with T shape structure towards an end of T-slot 10, thereby vertical rod 7 is linked to each other by T-slot 10 with the collar 11, and vertical rod 7 can be around the collar 11 motions; The other end of described vertical rod 7 and described back free bearing 6 are hinged; Described sliding sleeve 8 is hinged on the middle part of vertical rod 7, and described hand lever 9 is slidingly connected with described sliding sleeve 8, described hand lever 9 towards an end of electronic cutter 4 and described before free bearing 5 hinged.The collar 11 endoporus are bellmouth 12.
The collar 11 is a half slide structure.Can carry out the processing of peeling, broken string to the lead optional position like this, as shown in Figure 3.
Insulating barrier 1 with the cutting cable knob is an example, during use, the collar 11 is enclosed within cable knob, operation hand lever 9, and the depth of cut is controlled to be the thickness of insulating barrier 1, does not contact, destroys core 2; Then, hold hand lever 9, rotation; At last, realize peeling.
