Description

Technical Field

[0001] This utility model relates to a stripping mechanism for making high-voltage cable heads, belonging to the field of cable head manufacturing. Background Technology

[0002] When fabricating 110kV high-voltage cable terminations, wire stripping is a crucial step that requires extreme care and precision to ensure safety and electrical performance. A cutting tool is commonly used in 110kV high-voltage cable termination; it's used to cut open the outer sheath of the cable. When using this tool, the operator holds the handle with both hands and moves the cutting edge along the length of the cable, repeating this several times until the sheath is cut open. This method requires the operator to maintain control of the tool while keeping it firmly on the cable, and to use a backward movement. There is a risk that the tool might slip off the cable due to operator error, potentially injuring the operator and posing a safety hazard. Furthermore, relying entirely on manual force to cut open the sheath of a 110kV high-voltage cable is time-consuming and labor-intensive. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a stripping mechanism for making high-voltage cable heads, so as to solve the problems mentioned in the background technology. This utility model realizes the use of a hammering method to replace the manual method of cutting open the outer sheath of the high-voltage cable, thereby improving safety.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage cable head stripping mechanism, comprising a high-voltage cable, a ring sleeved on the high-voltage cable, a connecting seat on the upper side of the ring, two screws installed between the connecting seat and the ring, one end of each screw penetrating the connecting seat and being positionally adjustable, two adjusting nuts threaded onto the screws on both sides of the connecting seat, two clamping plates fixedly connected to the side of the connecting seat away from the ring, an inclined knife handle inserted between the two clamping plates, a knife head installed at one end of the knife handle, the knife handle being connected to the two clamping plates by fasteners formed by two sets of screws and positioning nuts, and a knocking plate connected to the two clamping plates on the upper side of the knife head.

[0005] Furthermore, two small holes are provided on one side of the handle, and two round holes are provided on the clamp plate that mate with the small holes. Screws are inserted into the channels formed by the small holes and the corresponding round holes, and a positioning nut is threaded to one end of the screws.

[0006] Furthermore, both of the clamping plates are provided with T-shaped support plates on their back sides for connection and fixation to the strike plate. One side of each T-shaped support plate has two through holes that mate with round holes, and the screws pass through the through holes on the two T-shaped support plates.

[0007] Furthermore, there is a gap between the T-shaped support plate and the clamping plate for inserting the hacksaw blade, and a clamping plate is fixedly connected to the side of the hammered plate facing the clamping plate. The clamping plate is inserted between the two clamping plates, and multiple strip-shaped openings are evenly provided on one side of the T-shaped support plate.

[0008] Furthermore, two through holes are symmetrically formed on the upper surface of the connector, and the screw passes through the through holes.

[0009] Furthermore, two threaded sleeves are symmetrically installed on the outer surface of the ring, and the end of the screw away from the connecting seat is threadedly connected to the threaded sleeve. The side of the threaded sleeve opposite to the ring is provided with an anti-loosening nut that is threadedly connected to the screw.

[0010] Furthermore, the side of the strike plate facing away from the clamping plate has two vertically arranged insertion slots, the lower end of the insertion slots is closed, and the side of the strike plate facing away from the clamping plate is provided with a protective plate. The side of the protective plate facing the strike plate has two insertion strips that cooperate with the insertion slots, and the insertion strips are inserted into the insertion slots.

[0011] Furthermore, the cross-section of the connector strip is dovetail-shaped, and the cross-section of the connector groove is dovetail-shaped.

[0012] Furthermore, a handle is installed at the center of the side of the connecting seat opposite to the struck plate, and a rubber sleeve is fitted onto the handle and adhered to the handle.

[0013] The beneficial effects of this utility model are:

[0014] 1. Place the ring onto the high-voltage cable, then position the cutter head outside the end of the high-voltage cable. Adjust the distance between the connecting seat and the ring. At this time, the screw moves within the through hole relative to the connecting seat. After the cutter head is outside the end of the high-voltage cable, use two adjusting nuts to limit the relative position of the screw and the connecting seat, so that the cutter head and the cutter handle maintain a constant relative position with the high-voltage cable. Then, the operator holds the connecting seat with one hand and uses a hammer to strike the plate being struck with the other hand. Under the action of the striking force, the ring moves along the high-voltage cable, and the cutter head slides along the high-voltage cable, thus cutting through the outer sheath of the high-voltage cable. This method of using a hammer to cut through the outer sheath of the high-voltage cable instead of manually avoids the cutter suddenly slipping off the high-voltage cable and injuring personnel, thus improving safety.

[0015] 2. Insert the connector strip on the guard plate into the connector slot on the plate to be struck, so that the guard plate and the plate to be struck can be connected. With the guard plate blocking the flow, the hammer head does not directly contact the plate to be struck, thereby extending the service life of the plate to be struck. When the guard plate is damaged, the guard plate can be replaced separately, which helps to reduce the cost of replacing parts.

[0016] 3. After the screw passes through the channel formed by the through hole, round hole, and small hole, tighten the positioning nut and lock the clamping plate on the hammer plate between the two clamping plates. This completes the fastener formed by the screw and positioning nut, which simultaneously restricts the relative positions of the tool holder, the hammer plate, and the clamping plates, reducing the number of screws used. Since there is a gap between the T-shaped support plate and the clamping plate, if the positioning nut and screw cannot be easily separated, simply insert the hacksaw blade into the gap between the T-shaped support plate and the clamping plate to cut the screw. This facilitates the later replacement of the hammer plate and the tool. Attached Figure Description

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1 and Figure 3This utility model provides a technical solution: a high-voltage cable head stripping mechanism, including a high-voltage cable 1, a ring 16 sleeved on the high-voltage cable 1, a connecting seat 13 on the upper side of the ring 16, a handle 9 installed in the middle of the side of the connecting seat 13 away from the striking plate 4, a rubber sleeve that is adhered to the handle 9, and the connecting seat 13 can be easily supported by gripping the handle 9.

[0025] See Figure 1 and Figure 3 Two screws 11 are installed between the connecting seat 13 and the ring 16. Two adjusting nuts 12 are threaded onto the screws 11 and located on both sides of the connecting seat 13. Two through holes 21 are symmetrically opened on the upper surface of the connecting seat 13, through which the screws 11 pass. Two threaded sleeves 15 are symmetrically installed on the outer surface of the ring 16, so that the end of the screw 11 away from the connecting seat 13 is threaded into the threaded sleeve 15, thereby assembling the screws 11 and the ring 16. On the side of the threaded sleeve 15 away from the ring 16, there is an anti-loosening nut 14 that is threaded into the screw 11, so that the anti-loosening nut 14 fits tightly with the threaded sleeve 15 to prevent the screws 11 from rotating at will.

[0026] See Figures 1-3 Two clamping plates 6 are fixedly connected to the side of the connecting seat 13 opposite to the ring 16. An inclined tool holder 18 is inserted between the two clamping plates 6. A tool head 2 is installed at one end of the tool holder 18. The tool holder 18 is connected to the two clamping plates 6 by fasteners formed by two sets of screws 7 and positioning nuts 8. Two small holes 19 are opened on one side of the tool holder 18. Two round holes 20 that mate with the small holes 19 are opened on the clamping plates 6. Screws 7 are inserted into the channels formed by the small holes 19 and the corresponding round holes 20. A positioning nut 8 is threaded to one end of the screw 7. The ring 16 is placed on the high-voltage cable 1, and then the tool head 2 is placed outside the end of the high-voltage cable 1. Then the distance between the connecting seat 13 and the ring 16 is adjusted. At this time, the screw 11 is relative to the high-voltage cable 16. The connecting seat 13 moves within the through hole 21. When the cutter head 2 is outside the end of the high-voltage cable 1, the two adjusting nuts 12 restrict the relative position of the screw 11 and the connecting seat 13, so that the cutter head 2 and the cutter 18 maintain a constant relative position with the high-voltage cable 1. Then, the operator holds the connecting seat 13 with one hand and holds a hammer with the other hand to strike the strike plate 4. Under the action of the striking force, the ring 16 moves along the high-voltage cable 1, and the cutter head 2 slides along the high-voltage cable 1. Thus, the cutter head 2 cuts through the outer sheath of the high-voltage cable 1, realizing the method of cutting through the outer sheath of the high-voltage cable 1 by striking instead of manually, avoiding the cutter from suddenly slipping off the high-voltage cable 1 and injuring personnel, thus improving safety.

[0027] See Figures 1-3The upper side of the blade head 2 is provided with a hammer-receiving plate 4 connected to two clamping plates 6. Each of the two clamping plates 6 has a T-shaped support plate 10 on its back side, which is fixedly connected to the hammer-receiving plate 4. One side of each T-shaped support plate 10 has two through holes that mate with round holes 20. A screw 7 passes through these through holes. A gap exists between the T-shaped support plate 10 and the clamping plates 6 for inserting the hacksaw blade. A clamping plate 5 is fixedly connected to the side of the hammer-receiving plate 4 facing the clamping plates 6. The clamping plate 5 is inserted between the two clamping plates 6. By evenly opening multiple strip-shaped openings 17 on one side of the T-shaped support plate 10, the amount of material used is reduced, allowing the screw to... After passing through the channel formed by the through hole, round hole 20 and small hole 19, screw on the positioning nut 8, and make the clamping plate 5 on the hammered plate 4 clamp between the two clamping plates 6. This completes the fastener formed by the screw 7 and the positioning nut 8, which simultaneously restricts the relative positions of the tool holder 18, the hammered plate 4 and the clamping plate 6, reducing the number of screws 7 used. At the same time, since there is a gap between the T-shaped support plate 10 and the clamping plate 6, when the positioning nut 8 and the screw 7 cannot be separated smoothly, the hacksaw blade can be inserted into the gap between the T-shaped support plate 10 and the clamping plate 6 to cut the screw 7, which facilitates the replacement of the hammered plate 4 and the tool later.

[0028] See Figure 1 , Figure 2 and Figure 4 The side of the hammer plate 4 facing away from the clamping plate 6 has two vertically arranged insertion slots. The lower end of the insertion slots is closed and has a dovetail-shaped cross-section. The side of the hammer plate 4 facing away from the clamping plate 6 is provided with a guard plate 3. The side of the guard plate 3 facing the hammer plate 4 is connected and fixed with two dovetail-shaped insertion strips 22 that cooperate with the insertion slots. The insertion strips 22 on the guard plate 3 are inserted into the insertion slots on the hammer plate 4 to realize the insertion of the guard plate 3 and the hammer plate 4. Under the obstruction of the guard plate 3, the hammer head does not directly contact the hammer plate 4, thereby extending the service life of the hammer plate 4. When the guard plate 3 is damaged, the guard plate 3 can be replaced separately, which helps to reduce the cost of replacing parts.
