Description

Multifunctional high efficiency high voltage electric cable stripper

The utility model relates to a kind of multifunctional efficient high voltage power cable peeler.

For many years, in power engineering, (the lift-off technology problem that is called for short the cable joint insulating barrier never is well solved high voltage power cable.The workman carries out sawing with bow saw and general cutter to cable insulation usually and eliminates, and wastes time and energy, and otch is not concordant yet.Domestic production recently a kind of cable stripping device, the patent No. is 92233384.X, it is by cutter and carry off that the cable device is supporting to be formed.Measure the length that to cut at cable socket with the method for line earlier during work, be 60mm or 100mm, cutter being enclosed within makes blade overlap with the line of being drawn again on the cable, rotary cutter, until insulating barrier has been cut, and then two of will carry off the cable device carry off dogging and go into to cut in the groove, and rotating screw bolt is slowly carried off out the insulating sleeve that is cut.This cable stripping device is because by cutter with carry off two kinds of instruments of cable device and forms, so operate loaded down with trivial detailsly, efficient is not high, when the little cable of cutting external diameter, also can occur off-centre and deflection, make cutter can not cut off insulating barrier or cut cable conductor bad.In addition, this device structure is not compact, the manufacturing cost height.

The purpose of this utility model is to provide a kind of at the problem that present cable stripping device exists to cut and carry off cable and finished by a mechanism, and two kinds of high cable joint insulating barrier peelers of compact conformation, efficient that operation can be carried out continuously.

The utility model is finished like this: multifunctional efficient high voltage power cable peeler mainly is made up of shed stick 1, screw rod 2, knife rest 3, cutter 4, cover tile 5, double-screw bolt 6, bearing inner sleeve 7, bearing outside 8, connection location cylinder 9, nut end cover 10, unsteady pressure head 11 and screw rod 12, shed stick 13.The outer round surface of the endoporus of bearing outside 8 and bearing inner sleeve 7 is and is slidingly matched.Cover tile 5 is connected in the below of bearing outside 8 by screw 22.Screw rod 2 one ends insert in the circular hole of cover tile 5, and are stuck in its cannelure by dog screw 16, make it rotatable, and axial endplay can not be arranged.Knife rest 3 is meshed by the external screw thread of the internal thread on it with screw rod 2, and has the double-screw bolt 6 that screws in cover tile 5 to insert in the slit of its end, prevents that it is around screw rod 2 swings.The left end of knife rest 3 has cutter 4, and fixing by screw 15.The other end of screw rod 2 is equipped with shed stick 1, and fixing by pin 14.Connect cylinder 9 two ends, location and all be shaped on internal thread, be connected with nut end cover 10 with bearing inner sleeve 7 respectively,, when carrying off cable, transmit the pulling force of nut end cover 10 simultaneously bearing outside 8 axial location.Connect edge, cylinder 9 two ends, location and circumferentially have inspection hole, and be carved with 60mm and two grooves of 100mm.The left end that connects location cylinder 9 is circumferentially located by screw 18.There is screwed hole at nut end cover 10 centers.The screw-threaded engagement at screw rod 12 and nut end cover 10 centers.The left end of screw rod 12 has a unsteady pressure head 11 that connects with screw, packing ring 20,21.The right-hand member of screw rod 12 has a shed stick 13 of fixing by alignment pin 19 in order to be suitable for the various outer diameter cable, make have when cutting cable good in neutrality, not eccentric and not deflection, the utility model is provided with one group of 3-4 the sleeve of fit mutually, its fit face does not have obvious gap, can be separated from each other easily, maximum sleeve outer diameter can with bearing inner sleeve 7 fits.Each length sleeve equates with screw 17 corresponding positions three holes that the aperture is more bigger than screw are arranged respectively on the sleeve with bearing inner sleeve 7.

Compare with existing cable joint insulation displacement device, the utility model has the advantages that:

1, this peeler is an integral body, cuts cable and carries off cable and carry out continuously, has improved operating efficiency, and the operating time shortens 50%;

2, needn't on cable, measure line in advance, simple to operate;

3, owing to need not carry off hook, so notch width can be narrow, so both can change cutter the rectangle cutter of 10 * 4mm into by the square cutter of 10 * 10mm, make the cost of charp tool descend 40%, significantly reduced cutter simultaneously, operate light;

4, reasonable in design, easily manufactured, cost reduces more than 30.

Fig. 1 is a structure chart of the present utility model;

Fig. 2 is the left view of Fig. 1.

The utility model is described in further detail below in conjunction with embodiment shown in the drawings.

During work, select suitable sleeve (or not needing sleeve) for use according to the external diameter of cutting cable, peeler is enclosed within on the required cable of peeling off, according to the cable joint that is cut is transition joint or end fitting, make the cut cable alignment connect graduation mark 60mm or the 90mm that locatees on the cylinder 9, screw three flat head screws 17.Head of screw screws in the insulating barrier degree of depth and is about 2-4mm.Adjust knife rest 3, making the distance between the lower plane on plane and cover tile 5 on it is the thickness of cable insulation.Adjust cutter 4, make the outer surface of blade contact cable insulation, screw fixedly cutter of screw 15.Hold shed stick 1 with the right hand knife rest 3 is rotated around cable clockwise, meanwhile, rotate counterclockwise screw rod 2, just can carry out cutting, till having cut cable insulation.Afterwards, by shed stick 13 screw rod 12 that turns clockwise, the pressure head 11 that floats promptly is pressed on the cable metal core end face, and to thrust left of its generation, screw rod 12 also produces a pulling force to the right to nut end cover 10 simultaneously, this power directly connects location cylinder 9 and reaches bearing inner sleeve 7, and reaches on the cable insulation through three screws 17.Continuous rotating screw bolt 12, cable insulation promptly apply under the twisting force of pressing on the sheath when pulling force and rotation and are slowly carried off out by integral body by helical trajectory from cable core, have finished the stripping operation of cable joint insulating barrier.
