Abstract
The invention discloses a stripping device for an outer shielding layer of a high-voltage cable. The stripping device comprises a first clamping block and a second clamping block which are oppositely arranged, wherein a stripping knife is arranged on the first clamping block; a smooth surface rolling shaft and a helicoidal surface rolling shaft are arranged side by side on the inner side of the second clamping block; and the first clamping block and the second clamping block are connected through a connection device. By adopting the technical scheme, the stripping time is greatly shortened, the work efficiency is improved, a smooth stripping surface is obtained, and a uniform transition surface is formed at the cutting port part on the outer shielding layer of the cable.
Description
Technical field
The present invention relates to a kind of high-tension cable outer shielding layer stripping off device.
Background technology
High pressure and extra-high-tension cable in the end a procedure oversheath all will carry out partial discharge and ac voltage withstanding delivery test after producing, during test, to carry out peeling off of oversheath and cable external shield, the strip length of external shield will decide according to the length of water terminal, terminal is done in general 110kV cable testing all will peel off 1.5m left and right, 3m is peeled off at cable two ends altogether, the external shield of 220kV cable is peeled off longer, general one end is peeled off and will be approached 2m, 4m cable will be shelled altogether in two ends, and existing traditional external shield stripping means is to adopt sheet glass to scrape, because the cable external shield of 110kV above is to adopt not strippable external shield material, when making cable terminal, high voltage test can only scrape with sheet glass, cable external shield for the about 3-4m of length is scraped with sheet glass, this is a muscular labor very laboriously, with sheet glass, scrape, sometimes careless easily scratch is pointed, both dangerous, speed is slow again.Scrape external shield and approximately spent altogether 2 hours above time, so, finish two terminals of cable and approximately spend about 3 hours altogether, add test duration, test one dish high-tension cable will spend more than 4 hours, and speed is slow, and efficiency is low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high-tension cable outer shielding layer stripping off device, has avoided the phenomenon that original stripping means peeling rate is slow, stripping is rough.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: high-tension cable outer shielding layer stripping off device, comprise the first grip block and the second grip block that are oppositely arranged, described the first grip block is provided with bark knife, the inner side of described the second grip block is provided with light face roller bearing and helicoid roller bearing side by side, and described the first grip block is connected by jockey with described the second grip block.
As preferably, described jockey comprises adjusting screw mandrel, connecting plate and at least two guide posts that are parallel to each other, the two ends of described guide post are fixed with described the first grip block and described connecting plate respectively, the middle part of described guide post is through described the second grip block, described adjusting screw mandrel and described connecting plate are threaded connection, and described adjusting screw mandrel one end backstop is in described the second grip block.
As preferably, this stripping off device also comprises toolsetting knob, and described toolsetting knob has one section of screw rod, and described screw rod and described the first grip block are threaded connection, and the end of described screw rod is connected with the tail end of described bark knife.
As preferably, the blade of described bark knife is provided with a bar hole, and described bark knife is fixed on the side of described the first grip block by being arranged in hold-down screw in described bar hole.
As preferably, on described the first grip block and described the second grip block, be respectively equipped with handle.
As preferably, the diameter of thread of described helicoid roller bearing is 32mm, and pitch is 1.5mm.
The present invention, owing to having adopted technique scheme, has shortened splitting time greatly, has improved operating efficiency, can obtain level and smooth stripping face, and forms uniform transition face in cable external shield incision.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
Fig. 1 and Figure 2 shows that high-tension cable outer shielding layer stripping off device of the present invention, comprise the first grip block 1 and the second grip block 2 that are oppositely arranged, described the first grip block 1 is provided with bark knife 3, the inner side of described the second grip block 2 is provided with light face roller bearing 4 and helicoid roller bearing 5 side by side, and described the first grip block 1 is connected by jockey with described the second grip block 2.Described jockey comprises adjusting screw mandrel 6, connecting plate 7 and at least two guide posts that are parallel to each other 8, the two ends of described guide post 8 are fixing with described the first grip block 1 and described connecting plate 7 respectively, the middle part of described guide post 8 is through described the second grip block 2, described adjusting screw mandrel 6 is threaded connection with described connecting plate 7, and described adjusting screw mandrel 6 one end backstops are in described the second grip block 2.On described the first grip block 1 and described the second grip block 2, be respectively equipped with handle 11.Figure 3 shows that helicoid roller bearing, the diameter of thread of described helicoid roller bearing 5 is 32mm, and pitch is 1.5mm.Helicoid rolling sleeve is located on a back shaft, and the two ends of this back shaft are articulated with respectively on described the second grip block, so that helicoid roller bearing can freely rotate.
This stripping off device also comprises toolsetting knob 9, and as shown in Figure 4, described toolsetting knob 9 has one section of screw rod 91, and described screw rod and described the first grip block 1 are threaded connection, and the end of described screw rod is connected with the tail end of described bark knife 3.The blade of described bark knife 3 is provided with a bar hole 31, and described bark knife 3 is fixed on the side of described the first grip block 1 by being arranged in hold-down screw 10 in described bar hole 31.
As shown in Figure 1, high-tension cable comprises conductor 16, insulating barrier 17 and outer shielding layer 18 from inside to outside successively.During use, will tighten folding adjusting handle wait shelling after cable insulation core end clips is held on outer shielding layer stripping off device, be screwed to just clamping cables insulated wire cores, and make light face roller bearing as finger opens, hold cable with helicoid roller bearing, till just tightening; Regulate the position of bark knife, mainly by toolsetting knob, rotate the position of moving to regulate bark knife, make the edge of a knife just head into 1mm left and right in cable outer shielding layer, then tighten hold-down screw, make cutter keep fixing, can not become flexible; While peeling off, both hands are held handle, and clockwise direction evenly rotates this device, during rotation, a little firmly to cable stripping direction, advance and clockwise rotate cutter, and outer shielding layer will be stripped from continually.This cutter also has autofeed function, and stripping pitch is even.When required test length is arrived in external shield stripping, first screw mandrel handwheel is unscrewed a bit, continued to clockwise rotate this and install about half-turn, just can cut off more glossily the external shield peeling off, the smooth rounding of transition tangent plane of external shield and insulating barrier.Adopt after high-tension cable outer shielding layer stripping off device of the present invention, two terminal splitting times of one dish high-tension cable are about 40 minutes, greatly shortened splitting time, improved operating efficiency, the smooth rounding of transition tangent plane of external shield and insulating barrier, also improve the external shield stripping quality of cable, also accelerated test speed.
