Combined cable tool
Technical field
The present invention relates to a kind of Combined cable tool, be particularly useful for the Combined cable tool of twisted polyethylene cable head manufacturing process.
Background technology
At present, in twisted polyethylene cable head fabrication, the stripping of main insulating layer and outer semiconducting layer is a very important and elaboration, and technological requirement is very high, particularly the section of outer semiconducting layer will link up, neatly very much, and any burr and uneven can not be arranged.This position electric field strength is the most concentrated, is the weakest place of cable end, and the cable end Common Accidents is caused by this position mostly.The quality of stripping quality directly affects the useful life of cable and the stability of safe operation.
At present, in construction, the quality of this link be by the workmen with common cable knife, control according to individual's technology and experience, how many workmen's technology quality, experiences differ greatly, uneven, be difficult to guarantee that a plurality of cable ends can both reach technological requirement.
Summary of the invention
The object of the invention is to have the deficiency that traditional electrical cable end manufacture method is brought now in order to overcome, a kind of Combined cable tool is provided, manufacture craft is low when having solved original manufacturing cable head, construction quality is uneven, thereby affects the problems such as cable useful life and harm equipment safety operation stability.
For achieving the above object, the technical solution used in the present invention is as follows:
Combined cable tool of the present invention, comprise upper bracket, lower carriage and blade, it is characterized in that: blade is packed on the swivelling tool-holder, the upper end of swivelling tool-holder and upper bracket are flexibly connected, and are provided with screw in the upper bracket, are provided with screw rod in the screw, the screw rod upper end is connected with handwheel, the lower end is connected with the driving wheel support, and the driving wheel support is provided with driving wheel, and the position corresponding to driving wheel on lower carriage is provided with fast pulley.
Among the present invention, be provided with chute at upper bracket, swivelling tool-holder is slidingly connected by tool carrier lock jack panel and upper bracket.
Among the present invention, also be provided with forming cutter on lower carriage, forming cutter is packed on the forming cutter screw mandrel.
Because the present invention has adopted technique scheme, this Combined cable tool has fundamentally changed the scene, only need adjust the blade amount of feeding in the construction period and just can satisfy technological requirement fully, improved operating efficiency, reduced labour intensity, guarantee construction quality, obtained the effect of getting twice the result with half the effort.Particularly operating personnel's personal safety, played a very good protection, really accomplished the work idea of " people-oriented, safety first ".

Embodiment
As shown in Figure 1 and Figure 2, Combined cable tool of the present invention comprises upper bracket 3, lower carriage 9 and blade 14, and blade 14 is packed on the swivelling tool-holder 13 by blade gland 16 and gland screw 15.Be provided with chute 18 at upper bracket 3, swivelling tool-holder 13 is slidingly connected by tool carrier lock jack panel 12 and upper bracket 3, and the lower end of swivelling tool-holder 13 is connected with lower carriage 9 by blade carrier wheel 17.Be provided with screw in the upper bracket 3, be provided with screw rod 2 in the screw, screw rod 2 upper ends are connected with handwheel 1, and the lower end is connected with driving wheel support 4, and driving wheel support 4 is provided with driving wheel 5, and the position corresponding to driving wheel on lower carriage 9 is provided with fast pulley 7.
Among the present invention, also be provided with forming cutter 6 on lower carriage 9, forming cutter 6 is packed on the forming cutter screw mandrel 11, and forming cutter screw mandrel 11 is socketed in forming cutter rest 8 and the lower carriage 9.
The course of work of the present invention is as follows:
1, rotates adjustment screw rod 2, make driving wheel 5, fast pulley 7 suitably contact (compression), can radially rotate in the cable outer semiconducting layer.
2, unclamp tool carrier lock jack panel 12, adjust blade 14 feeding depths (deciding on semi-conductive layer thickness), must not injure main insulation.
3, the fastening effect of driving wheel 5 and fast pulley 7 this cutter radially rotated the cut-out work of namely finishing in a week, owing to can make the cutter seam dock to satisfy technological requirement fully.
4, in the time of need radially cutting off main insulation, can when cutter rotates, push down tool carrier lock jack panel 12, make gradually ecto-entad feeding of blade 14, turn and press in conjunction with finishing cut-out work.
5, by adjusting the amount of feeding of forming cutter 6, can finish simultaneously the work of main insulation cut-out and the 45 ° of chamferings in end, very efficient, safety.
