Abstract
The invention relates to a longitudinal electric cutter for a cable outer sheath. The longitudinal electric cutter for the cable outer sheath comprises an upper handle and a lower handle. The lower handle is connected with a power head support through a reset spring. The upper handle is fixedly connected with the power head support. The power head support is fixedly provided with a blade. A riding wheel I and a riding wheel II are fixed below the blade. A power head is connected with a power source through a connecting shaft I. When the longitudinal electric cutter for the cable outer sheath is used for sectioning a cable, the sectioned cable moves on the riding wheels, the rotating direction of the blade is opposite to the feed direction of the cable, the blade cutting resistance is smaller than the traction of the cable, the sectioning efficiency of the cable outer sheath can be improved, labor intensity is relieved, damage to the cable is reduced, and potential safety hazards are avoided. Different sizes of blades can be installed on the power head support, due to the distance between the blade and the cable, the cables with different diameters can be sectioned conveniently, and the longitudinal electric cutter for the cable outer sheath is affordable.
Description
Technical field
The present invention relates to a kind of cable jacket electric chopper, be especially applicable to longitudinal cutting of secondary cable jacket, belong to field of machining.
Background technology
Along with increasing the weight of of the quickening of extra-high voltage grid and town and country distribution network construction paces, transformer station's new website construction, the transformation of old station, technological transformation task, substation secondary cable stripping work just becomes an important step in engineering, wherein putting into operation of a circuit only, just needs up to a hundred of stripping secondary cable tens.Secondary cable jacket, mostly manufactured by igelite material, these material insulation property are good, corrosion-resistant, heat-resisting, water-fast, tightness is very strong, but its temperature influence is larger, after temperature reduces, due to the variation of molecular structure, its hardness is increased greatly, bring great inconvenience to cable construction.Because current operation field does not have secondary cable special stripping and cutting tool, staff is very dangerous in the time using common cable cutter to carry out longitudinal stripping to cable, the phenomenon that workmen is hurt by blade often occurs, and efficiency is low, and labour intensity is high.And because staff's method of operation, dynamics are different; often can damage the halfway phenomenon of cable core insulating barrier and heart yearn or peeling; if cable insulation is compromised, easily cause secondary loop short circuit, bring hidden danger to power network safety operation.
Summary of the invention
The technical problem to be solved in the present invention is that traditional cable cutter stripping secondary cable efficiency is low, has potential safety hazard.For addressing the above problem, a kind of cable jacket longitudinal electric cutting knife is provided, solve original cable stripping labor intensity large, easily endanger personal safety and damage the problems such as cable.
The object of the invention is to realize in the following manner:
The present invention is mainly connected with power head bracket by back-moving spring by lower handle, and upper handle and power head bracket are fixedly connected; On described power head bracket, be fixed with blade; Described unit head is connected with power source by connecting axle I; Described blade below is fixed with support roller I and support roller II.
Described support roller I be fixed on blade below parallel with support roller II.
When operating state, described upper handle is not parallel with lower handle, and unit head and handle are 90 °.
The direction of described blade rotation is contrary with cable direction of feed, and blade cuts resistance is less than cable pulling power.
Described power head bracket is fixed on safety guard fixed station by safety guard fixing threaded hole.
Described upper handle is fixedly connected with stop-nut by stationary knife screw with lower handle one end.
With respect to prior art, the present invention has following beneficial effect: 1, dissectd cable and move on support roller, the direction of blade rotation is contrary with cable direction of feed, blade cuts resistance is less than cable pulling power, can improve the stripping efficiency of cable jacket, reduce labour intensity, reduced the infringement of cable, avoided potential safety hazard.2, power knife support of the present invention can be installed the blade of different model size, and the distance between blade and cable can facilitate the cable of stripping different thicknesses, economic and practical.3, the present invention is simple in structure, easy to operate, practical, and cost is low.4, in the middle of power head bracket and lower handle, be connected with back-moving spring, when Manual press, the power saving that saves time is laborsaving.

Embodiment
As depicted in figs. 1 and 2, a kind of secondary cable jacket longitudinal electric cutting knife of the present invention, is connected with power head bracket 2 by back-moving spring 7 by lower handle 10, and upper handle 8 is fixedly connected with power head bracket 2; On power head bracket 2, pass through push type broach screw 13, pressure knife block 14 and folder cutter plain cushion 15 fixed blades 3; Unit head 20 is connected with power source by connecting axle I 4; Blade 3 belows are fixed with support roller I 6 and support roller II 23.Support roller I 6 be fixed on blade 3 belows parallel with support roller II 23.In the middle of power head bracket 2 and lower handle 8, be connected with back-moving spring 7.When operating state, described upper handle 8 is not parallel with lower handle 10, and unit head 20 is 90 ° with handle.The direction that blade 3 rotates is contrary with cable 5 directions of feed, and blade 3 Cutting Drags are less than cable 5 tractive effort, designs more stablely, and unit head 20 is with cutting blade high speed rotating, vertically cable jacket is dissectd rapidly.Power head bracket 2 is fixed on safety guard fixed station 1 by safety guard fixing threaded hole 21.Upper handle 8 is fixedly connected with stop-nut 12 by stationary knife screw 11 with lower handle 10 one end.Upper handle 10 connects with support roller II 23 by handle fixed screw 9, and junction is provided with support roller plain cushion 22; Coupling spindle II 18 connects with support roller I 6 by self-locking nut 19; Support roller is arranged in supporting-roller shaft 16, the flexible back-up ring 17 of support roller arranged outside.
Specific works process is as follows:
Adjust stationary knife screw 11 and make cutting knife incision size correct, tighten stop-nut 12 after errorless, open unit head 20 and determine that blade 3 installation directions are contrary with cable 5 directions of feed.Cable is placed between cutter blade 3 and support roller I 6 and support roller II 23, presses down upper handle 8, safety guard move up (press off safety guard need certain dynamics).Starting cutting from the position of cable socket number meter, when work, coordinate enforcement by two people, people's attached cable, another people holds cutter regression backward.After having cut, shut switch, release handle, under the effect of back-moving spring 7, upper lower handle is opened naturally, and guard shield seals blade 3 immediately completely, and blade 3 immediate recoveries are guard mode.
