Description

Technical Field

[0001] The invention relates to the field of power supply cables, and in particular to a high-voltage cable terminal head positioning and stripping device. Background Art

[0002] Before stripping the high-voltage cable terminal head, prepare professional cable stripping tools, such as cable knives, wire strippers, etc. Wear appropriate protective equipment, such as insulating gloves, goggles, etc. Then determine the stripping length, and determine the length of the cable outer sheath, steel armor, inner sheath and insulation layer to be stripped according to the specifications and requirements of the cable terminal head. Generally speaking, the stripping length of the outer sheath should be slightly longer than the installation length of the terminal head, and the stripping length of the steel armor and inner sheath should be determined according to the specific situation. When stripping the high-voltage cable terminal head, use a cable knife to make a circular incision on the outer sheath of the cable. The depth of the incision should be moderate, and the outer sheath should be stripped along the incision. Be careful not to scratch the steel armor and insulation layer inside the cable. Strip the insulation layer and determine the stripping length of the insulation layer according to the requirements of the terminal head. Use professional insulation stripping tools, such as wire strippers or cable knives, to carefully strip the insulation layer, and be careful not to damage the cable conductor. After stripping, wipe the surface of the cable conductor and insulation layer with a cleaning cloth to remove dust and impurities.

[0003] If the stripping length cannot be determined when stripping the wire at the high-voltage cable terminal, the following series of effects may occur: if the stripping length of the high-voltage cable terminal is too long, the cable conductor is exposed too much and is easily affected by external environmental factors, such as humid air, dust, etc., which may cause oxidation and corrosion of the conductor, thereby increasing resistance, affecting the electrical conductivity of the cable, and reducing the efficiency of power transmission. The risk of phase-to-phase short circuit or ground short circuit is increased, because the overly long conductor is more likely to contact or approach surrounding objects, which may cause faults under the action of high voltage. If the stripping length is too short, the cable terminal and the cable conductor are not tightly connected, and the contact resistance increases, which will also affect the electrical conductivity and cause local heating, which may cause a fire in severe cases. Therefore, whether the stripping length is too long or too short, it may affect the insulation performance of the cable, reduce the voltage resistance of the cable, and increase the risk of electric shock. Therefore, the present invention provides a high-voltage cable terminal positioning and stripping device. Summary of the invention

[0054] Working principle:

[0055] When stripping the high-voltage cable terminal head, first measure the length of the high-voltage cable terminal head that needs to be stripped. The measurement method is mainly to use a ruler or a soft ruler for measurement. After the measurement is completed, record the measured length of the high-voltage cable terminal head. Then, rotate the rotating plate 12 at the tail. The rotating plate 12 is fixedly connected to the transverse screw rod 4. When the rotating plate 12 rotates, it drives the transverse screw rod 4 to rotate. The transverse screw rod 4 is connected to the nut 11 by a threaded structure. When the rotating plate 12 is rotated, the rotating plate 12 will drive the transverse screw rod 4 to move, and the end of the transverse screw rod 4 is connected to the rolling bearing 13. The inner ring surface of the rolling bearing 13 is fixedly connected, and the outer ring surface of the rolling bearing 13 is fixedly connected to one side of the positioning plate 6. When the transverse screw rod 4 rotates in the rolling bearing 14, the positioning plate 6 is pushed horizontally by the transverse screw rod 4, and two slide rods 7 are inserted into the holes on the positioning plate, and the slide rods 7 have scale values, so the positioning plate is pushed to the distance where the stripping length of the high-voltage cable terminal head is required. The distance L is the stripping length of the high-voltage cable terminal head. When the stripping length is determined, the cable 8 is inserted between the cable pulley 32 and the stripping knife assembly 34, and the stripping frame 31 is rotated. The adjusting plate 37 is fixedly connected to the top of the longitudinal push rod 33. When the adjusting plate 37 is rotated, the longitudinal push rod 33 is driven to rotate, and the longitudinal push rod 33 is fixedly connected to the inner ring surface of the push rod bearing 344, and the outer ring surface of the push rod bearing 344 is fixedly connected to the top of the transverse bracket 343. Therefore, by rotating the adjusting plate 37, the wire stripping knife assembly 34 can be driven to move vertically up and down in the wire cavity 38 of the adjusting stripping mechanism 3. Through the movement of the wire stripping knife assembly 34, the bottom of the wire stripping knife 341 on the wire stripping knife assembly 34 is pressed against the cable 8 The top of the cable 8 is then pushed horizontally. When the cable 8 moves between the cable pulley 32 and the wire stripping knife assembly 34, the cable pulley 32 below the cable 8 serves to convey the cable, and the wire stripping knife 341 on the wire stripping knife assembly 34 strips off the insulation layer of the cable 8. The cable 8 is continued to be pushed until the end of the cable 8 is pressed against the positioning plate 6. After the stripping is completed, the cable 8 is pulled out from between the cable pulley 32 and the wire stripping knife assembly 34, and the above steps are repeated to continue the stripping process of the next cable 8, thereby completing the stripping of multiple cables of the same length.
