Description

Technical Field

[0001] The present invention relates to the technical field of power cable stripping devices, and particularly to a power cable stripping machine. Background Art

[0002] Power cables are cables used for transmitting and distributing electrical energy. Power cables are commonly used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. Cable installation, use, and recycling all require cable stripping.

[0003] The power cable stripping device with the patent publication number CN108666852A places the cable body on the lower pressing block and three cable roller frames in sequence from right to left, and then starts the first servo drive motor to drive the circular gear to rotate. According to the meshing principle of gear and rack, the lifting rack will slowly move downward until the upper pressing block clamps the right end of the cable body in cooperation with the lower pressing block. The added lifting guide slider and vertical guide rail ensure the stability of the lifting rack during the lifting process. Then, the heat insulation cover is opened, and the very hot heating wire bakes and burns the cable body at high temperature until the cable skin at that place is charred and softened. The clamping head grabs the left end of the cable body, and the second servo drive motor is started to drive the horizontal rotating screw. Due to the action of an internal thread hole and a guiding through hole on the added vertical moving column.

[0004] The above patent provides a power cable stripping machine, which solves the problems of poor effect and low efficiency caused by the complicated design of the traditional stripping device, improves the stripping efficiency of power cables, has stronger practicability and a wide application range. However, when the stripping length becomes shorter and shorter, the cutting tool or cutting part of the stripping device may only act on the tail end part of the cable, which may cause stress concentration at the tail end during the stripping process, forming local stress. Due to the structural characteristics of the cable, the stress at the tail end may increase after stripping. In this case, the cable may be more likely to suffer mechanical damage during subsequent use, and even lead to cable fracture or failure. Summary of the Invention

[0010] According to the above technical solution, the other end of the fixed rod contacts the fixed rotating plate. A square groove is formed on the upper surface of the cross bar. The bolt slides on the inner wall of the square groove. The bolt slides on the inner wall of the square groove to limit the cross bar.

The fifth spring is provided to drive the sliding cutting plate back to its original position.

[0014] The present invention provides a power cable stripping machine. It has the following beneficial effects: (1) In this invention, when the remaining length of the cable being stripped cannot press down the rotating plate, the limit between the clamping plate and the outer rod is released, and the clamping plate will be pushed out by the third spring to clamp the end of the cable, avoiding the excessive stress at the end of the cable from affecting the stripping. The stripped part will bear a certain tensile stress. If the insulation layer at the stripped end is stripped too short, it may lead to stress concentration at the end during the stripping process, forming local stress. The conductor inside the cable may be affected by the tensile force, resulting in deformation or damage of the conductor, and it is more likely to cause wear or peeling of the conductor.

[0015] (2) In this invention, the fixed rotating plate is blocked by the fixed rod so that the fixed rotating plate cannot rotate. The inability of the fixed rotating plate to rotate will lift the sliding plate through contact with the fixed block, preventing the sliding plate from descending when the cable skin is not completely stripped. The sudden drop of the upper peeling wheel may cause the stripping process to become uneven, possibly resulting in over - stripping in some areas while other areas are not stripped, affecting the subsequent operation of the cable. If the upper peeling wheel drops too fast or with too much force, it may cause physical damage to the conductor inside the cable, affecting the electrical performance of the cable.

[0016] (3) In this invention, when stripping the cable, the cable stripping mechanism will start to rotate to strip the cable. The stripped cable will be discharged through the guiding cylinder, and the stripped skin will enter the interior of the collection box through the slideway. When the cable stripping mechanism rotates, the rotating shaft of the lower peeling wheel will rotate. The rotation of the rotating shaft of the lower peeling wheel will drive the rotating pressure rod to rotate. The rotation of the rotating pressure rod will contact the sliding cutting plate and push the sliding cutting plate towards the fixed cutting plate to cut the stripped skin, strengthening the collection of the skin. By cutting and collecting the stripped cable skin, it is possible to avoid the formation of messy waste on - site. This helps to keep the working environment clean, improve work efficiency, and reduce the risk of accidents caused by debris. Description of the Drawings

[0025] The other end of the fixed rod 208 is in contact with the fixed rotating plate 206. A square groove is formed on the upper surface of the cross bar 209.

[0029] During the operation of this embodiment: When the guide wheel 101 moves, it will push the fixed frame 103 to move the inner plate. When the inner plate of the fixed frame 103 moves, it will push the push plate 211 to move. When the push plate 211 moves, it will push the first hydraulic rod 202 to move into the first hydraulic cylinder 201, pushing the liquid inside the first hydraulic cylinder 201 into the second hydraulic cylinder 203. When the liquid inside the second hydraulic cylinder 203 increases, it will push the second hydraulic rod 204 to move. When the second hydraulic rod 204 moves, it will push the sliding plate 205 to move upward. When the sliding plate 205 moves upward, it will drive the lower peeling wheel to move. When the sliding plate 205 moves, it will drive the fixed rotating plate 206 to move. When the fixed rotating plate 206 moves, it will contact the fixed block 207. When the length of the cable is too short to contact the guide wheel 101, the guide wheel 101 will return to its original position. When the guide wheel 101 returns to its original position, it will drive the first hydraulic rod 202 to return to its original position. When the first hydraulic rod 202 returns to its original position, it will pump the excess liquid inside the second hydraulic cylinder 203 back into the first hydraulic cylinder 201. When the liquid inside the second hydraulic cylinder 203 decreases, the second hydraulic rod 204 will release the supporting force on the sliding plate 205, and the fixed rotating plate 206 will be blocked by the fixed rod 208, preventing the fixed rotating plate 206 from rotating. When the fixed rotating plate 206 cannot rotate, it will support the sliding plate 205 through contact with the fixed block 207, preventing the sliding plate 205 from descending before the cable skin is completely peeled. When the cable peeling is completed, rotate the bolt 210 to make the bolt 210 lose contact with the cross bar 209, releasing the limit on the cross bar 209. Pull the cross bar 209. When the cross bar 209 moves, it will drive the fixed rod 208 to move. When the fixed rod 208 moves, it will release the limit on the fixed rotating plate 206, causing the sliding plate 205 to return to its original position.

[0030] When peeling the cable, the cable peeling mechanism 6 will start to rotate to peel the cable. The peeled cable will be discharged through the guide cylinder 7, and the peeled skin will enter the collection box 3 through the slideway 302. When the cable peeling mechanism 6 rotates, the rotating shaft of the lower peeling wheel will rotate. When the rotating shaft of the lower peeling wheel rotates, it will drive the rotating pressure rod 304 to rotate. When the rotating pressure rod 304 rotates, it will contact the sliding cutting plate 305 and push the sliding cutting plate 305 towards the fixed cutting plate 301 to cut the peeled skin, strengthening the collection of the skin. Because the sheared and scattered skin chips will fall onto the surface of the inclined platform 303, the skin chips will slide into the collection box 3 through the inclined surface of the inclined platform 303. When the rotating pressure rod 304 rotates, it will contact the lower slide plate 306 and push the lower slide plate 306 to move. When the lower slide plate 306 moves, it will push the conical plate 307 to move. When the conical plate 307 moves, it will push the moving rod 308 to move. When the moving rod 308 moves, it will drive the pushing plate 309 to move towards both sides of the collection box 3. When the pushing plate 309 moves towards both sides of the collection box 3, it will be blocked by the limit block 310, preventing the pushing plate 309 from rotating when it moves towards both sides of the collection box 3. When the moving rod 308 is pushed back to its original position by the fourth spring, the pushing plate 309 will rotate because the frictional force with the bottom of the collection box 3 is too large.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
