Description

Technical Field

[0001] The invention relates to the technical field of electric power, and in particular to a secondary cable stripping tool. Background Art

[0002] With the rapid development of the power industry, power equipment occupies an important position in the power industry, and power equipment must rely on secondary cables to achieve functions such as conduction, control, and signal transmission. The quality of the secondary cable insulation layer has become the key to the safe operation of power equipment and power grids and the safety of operators, so the importance of stripping the secondary cable insulation layer has also been highly valued by power people. At present, the stripping method of the secondary cable insulation layer in the power industry mainly relies on operators using a knife to strip the insulation layer of the secondary cable, which has the following shortcomings:

[0003] 1. Uneven force and poor stripping quality: The operator uses a knife to strip the insulation layer of the secondary cable. Because it is difficult to control the strength of the knife, the force of the knife stripping the insulation layer of the secondary cable is uneven. Sometimes the force is too strong, which will damage the insulation performance of the secondary line. Sometimes the force is too small, which cannot achieve the effect of separating the insulation layer of the secondary cable from the secondary line inside.

[0004] 2. Uneven force, low stripping efficiency: Operators use a knife to strip the insulation layer of the secondary cable. Without considering safety and insulation performance, they feel that the efficiency is high, but they do not fully consider environmental factors. At room temperature or when the temperature is high (summer), the cable insulation layer is relatively soft, and the knife is easy to cut, so the efficiency is high. If the temperature is low (winter), the secondary cable insulation layer is hard, and it is difficult to strip the insulation layer with a knife. After all, human strength is limited, and the force is uneven, sometimes strong and sometimes weak, which affects work efficiency. In addition, during the cutting process, the knife's trajectory is easy to deviate, which leads to unsafe things.

[0005] 3. Uneven force creates safety hazards: During the peeling process, if the operator does not apply enough force or the direction of the knife is not fixed, the knife's movement trajectory may deviate and scratch the operator or others.

[0006] Therefore, during the stripping process of the secondary cable insulation layer, how to maximize the protection of the secondary cable insulation performance while ensuring work efficiency and the safety of operators becomes the key to the improved design of the secondary cable insulation layer stripping. Summary of the invention

[0007] In view of the above technical problems, the present invention provides a secondary cable stripping tool that solves the above problems, which can effectively improve work efficiency, ensure the safety of operators, and more importantly, ensure that the insulation performance of the secondary wire is not affected after the secondary cable is stripped.

[0008] The present invention is achieved through the following technical solutions:

[0009] A secondary cable stripping tool comprises an annular bracket, wherein a cable slide I, a cable slide II and a cable pressing block are sequentially distributed along the annular direction in the annular bracket; the cable pressing block is in a hemispherical structure, and the spherical end is used to contact the cable, the flat end of the cable pressing block is connected to the annular bracket through a pressure head, a blade is fixed on the pressure head, and the tip of the blade is used to strip the cable after passing through the spherical end of the cable pressing block; the cable slide I and the cable slide II have the same structure and are distributed in a mirror-symmetrical manner with the cable pressing block as the center; in the direction of the axial centerline of the annular bracket, the surfaces of the cable slide I and the cable slide II used to contact the cable are both in an arc surface structure, and the generatrix direction of the arc surface structure is intersecting or perpendicular to the moving direction of the cable; when the cable passes through the annular bracket and is stripped by the blade, the cable is clamped and fixed by the cable slide I, the cable slide II and the cable pressing block; and in the radial plane of the annular bracket, the contact points of the cable with the cable slide I, the cable slide II and the cable pressing block are distributed in a triangular shape.

[0010] During conventional stripping operations, workers use a knife to strip the insulation layer of the secondary cable. It is difficult to control the force. If the force is too great, the insulation performance of the secondary line will be damaged, and the trajectory of the knife is easy to deviate during the stripping process, which may lead to unsafe situations. If the force is too small, it is difficult for the knife to strip the insulation layer, and the effect of separating the insulation layer of the secondary cable from the secondary line inside cannot be achieved, affecting work efficiency.

[0011] The working principle of the present invention is as follows: an annular bracket is used as a skeleton structure, and three cable support points are distributed in the annular bracket along the annular direction, namely, cable slideway I, cable slideway II, and cable pressing block. When in use, the cable is passed through the annular bracket, and the cable slideway I, cable slideway II, and cable pressing block surround the cable along the circumference of the cable and are in close contact with the cable; the cable or the annular bracket is pulled, and the cable stripping layer is cut by the blade passing through the spherical end of the cable pressing block. Since the tool provided by the present invention can be made into a small portable stripping tool, only one operator is required to operate it. When in use, the tool can be held tightly with one hand, and the cable can be held tightly with the other hand, and the cable can be pulled to make the cable move relative to the annular bracket. The present invention uses a three-point fixing structure around the circumference of the cable to clamp the cable, which effectively fixes the cable while reducing the contact area with the cable, ensuring that the depth of the blade cutting the cable is always consistent, the cutting force is uniform, and the blade movement trajectory does not deviate, the cutting force is uniform, the stripping efficiency is improved, and the safety of the operator is guaranteed. In addition, the surfaces of cable slide I and cable slide II that are used to contact the cable are both in an arc-shaped curved surface structure, and the direction of the busbar of the arc-shaped curved surface structure is intersecting or perpendicular to the direction of cable movement, so that during the relative movement between the annular bracket and the cable, the cable contacts the cable slide I and cable slide II with as small a contact area as possible, reducing friction resistance; and the arc-shaped slopes on both sides of the contact part and the hemispherical structure of the cable pressure block both guide the cable. When pulling the cable, the operator does not need to consider keeping the cable axis perpendicular to the plane of the annular bracket at the stripping point, and can pull it at will, further improving work efficiency. If the edge of cable slide I, cable slide II or cable pressure block is a multi-edge structure, during the process of pulling the cable, the outer wall of the cable will generate greater friction resistance with the edge, which is not easy to operate.

[0012] Furthermore, the annular bracket as a whole is a closed ring structure or a ring structure with a break; the radial cross-sectional shape of the annular bracket is composed of one or more curved segments, including a circle; or is composed of multiple straight lines, including a square, a regular hexagon; or is an irregular structure composed of straight lines and curves.

[0013] The shape of the annular bracket provided by the present invention is not limited as long as it can serve as a keel, and miniaturization is preferred.

[0014] Furthermore, a through hole is provided on the side wall of the annular bracket, and the pressure head adopts a tubular structure. The bottom end of the tubular structure passes through the through hole and extends into the annular bracket. A limit ring is provided at the port of the bottom pipe section of the tubular structure; an adjusting screw, a blade mounting rod, and a blade are provided in sequence in the tubular structure, one end of the adjusting screw is screwed into the top pipe section of the tubular structure through a threaded connection, and the end of the adjusting screw extending into the tubular structure is in contact with one end of the blade mounting rod, and the other end of the blade mounting rod is fixedly connected to the tail end of the blade, and the tip of the blade extends out of the tubular structure and then passes through the spherical end of the cable pressure block; a compression spring is also provided outside the blade, and the axial ends of the compression spring are provided between the blade mounting rod and the limit ring; the top end face of the pressure head is provided with an embossed scale.

[0015] The present invention adopts a combination of spring, stamping scale, and adjusting screw to control the depth (force) of the blade. The thickness of the cable stripping layer can be adjusted according to the actual stripping requirements, so that the blade has uniform force and consistent depth during the movement of the blade, thereby ensuring that the insulation of the secondary line is not damaged and improving the insulation performance. For example, when it is necessary to increase the stripping depth of the blade, that is, to increase the length of the blade tip extending out of the cable pressure block, the adjusting screw can be rotated clockwise to further screw into the pressure head, and at the same time, the adjusting screw pushes the blade mounting rod to move forward synchronously along the axial direction of the pressure head, and the blade mounting rod drives the blade to move forward, and the length of the blade tip extending out of the cable pressure block increases; during the adjustment process, the blade mounting rod will apply pressure to the compression spring during the forward movement of the blade mounting rod, and the compression spring is compressed, which is conducive to improving the stability of the adjustment of the adjusting screw. On the contrary, when it is necessary to reduce the stripping depth of the blade, that is, to reduce the length of the blade tip extending out of the cable pressure block, the adjusting screw can be rotated counterclockwise to further screw out of the pressure head. At this time, the pressure applied to the compression spring is canceled, and the compression spring is restored to drive the blade mounting rod and the blade to reset, thereby reducing the length of the blade tip extending out of the cable pressure block.

[0016] Furthermore, the blade is detachably connected to the blade mounting rod via screws.

[0017] The blade and the blade mounting rod are detachably connected by screws, the structure is simple, and the disassembly, assembly and replacement operations are convenient.

[0018] Furthermore, the outer wall of the pressure head is threadably connected to the through hole, and a locking nut is also provided on the pressure head.

[0019] The pressure head is threadedly connected to the annular bracket, so that the length of the pressure head extending into the annular bracket can be conveniently adjusted, and the length of the cable pressure block extending into the annular bracket can be adjusted.

[0020] Furthermore, the cable slide I or cable slide II adopts an adjustable component, which includes a mounting plate, a guide roller and two auxiliary rollers, and the axial directions of the mounting plate, the guide roller and the two auxiliary rollers are arranged in the same direction; the two ends of the two auxiliary rollers are fixed on the mounting plate, and a guide roller is arranged between the two auxiliary rollers, and the two ends of the guide roller are connected to the mounting plate through a connecting rod; the axial direction of the mounting plate is cross-sectionally or perpendicular to the cable movement direction; on the radial section of the mounting plate, the vertex line of the guide roller and the two auxiliary rollers is a circular arc curve.

[0021] The guide roller and the auxiliary roller here can adopt a cylindrical structure or a semi-cylindrical structure.

[0022] Furthermore, one end of the connecting rod is threadedly connected to the mounting plate, and the other end of the connecting rod is rotatably connected to the end of the guide roller shaft via a bearing.

[0023] The connecting rod and the guide roller are arranged in a vertical state; a threaded hole can be opened on the mounting plate, and even a threaded hole can be opened on the annular bracket as an extension of the threaded hole on the mounting plate; by rotating the connecting rod clockwise, the connecting rod is further screwed into the threaded hole on the mounting plate, driving the guide roller to get closer to the mounting plate, and the distance between the guide roller and the mounting plate is reduced; by rotating the connecting rod counterclockwise, the connecting rod is further screwed out of the threaded hole on the mounting plate, driving the guide roller to get further away from the mounting plate, and the distance between the guide roller and the mounting plate is increased. Combined with the rotating pressure head to adjust the length of the cable pressing block extending into the annular bracket, it can be ensured that for cables of different outer diameters, the distances from the contact points of the cable slide I, cable slide II, and cable pressing block to the cable center are equal, and in particular, the three-point structure fixing the cable at equal angles (the cable slide I, cable slide II, and cable pressing block are circumferentially evenly spaced in the annular bracket with an angle of 120°) can be achieved.

[0024] Furthermore, strip holes are provided on the plate surface near the axial ends of the mounting plate, the strip holes extend radially along the mounting plate, and the radial cross-section of the strip holes is an inverted T-shaped structure; connecting plates are provided at the axial ends of the auxiliary roller shaft, the heads of the bolts are clamped in the strip holes, the rods of the bolts extend out of the strip holes, penetrate the connecting plates and are locked and fixed by nuts.

[0025] By cooperating with the bolt and the strip hole, the distance between the two auxiliary rollers can be adjusted to cooperate with the guide roller.

[0026] Furthermore, the guide roller includes a fixed shaft and a rotating roller, and the fixed shaft and the rotating roller are rotatably connected via a bearing.

[0027] The guide roller shaft preferably comprises a fixed shaft and a rotating roller. During the cable pulling process, the outer wall of the cable contacts the outer wall of the rotating roller. The friction resistance between the outer wall of the cable and the outer wall of the rotating roller drives the rotating roller to rotate relative to the fixed shaft, converting the friction force into a rotational action, thereby further reducing the friction resistance of pulling the cable.

[0028] Furthermore, the cable slideway I and the cable slideway II both adopt an arc-shaped plate structure, and the arch surface of the arc-shaped plate structure contacts the cable, which has a simple structure and low cost.

[0029] The present invention has the following advantages and beneficial effects:

[0030] The secondary cable stripping tool provided by the present invention adopts a three-point fixing structure to fix the cable in the annular bracket, and the stripping operation is performed through the tip of the knife set at one "point", thereby ensuring that the trajectory of the knife does not deviate and the stripping force is uniform; a pressure spring, an embossed scale, and an adjusting screw are combined to control the depth (force) of the blade, and a locking nut is added to fix the pressure head, so that the force of the blade is uniform, so that the secondary cable is subjected to uniform force, and there is no need for people to control the force of the knife. Only by pulling the secondary cable stripping tool can the stripping of the secondary cable be quickly completed, and when the insulation layer of the secondary cable is stripped, it can be ensured that the insulation of the secondary line is not damaged, thereby improving the insulation performance and ensuring the personal safety of the operator.

[0031] The secondary cable stripping tool provided by the present invention has been tested many times (stripping secondary cables) and has significant effects. Compared with manual cable stripping with a stripping knife, the tool has higher efficiency, faster speed, higher safety, and less insulation damage. The stripped secondary cable insulation layer is in a straight line with a consistent depth and has a higher process. BRIEF DESCRIPTION OF THE DRAWINGS
