Description

Technical Field

[0001] This invention relates to the field of cable installation tools, and in particular to a tool for installing high-voltage power cables. Background Technology

[0002] In the construction and operation of power engineering, the installation of high-voltage cables is one of the core processes, and precise cable cutting is a key prerequisite for ensuring installation quality and the stability of subsequent power transmission. As power systems develop towards higher voltage and larger capacity, the diameter of high-voltage cables is gradually increasing, and the insulation layer and conductor structure are becoming more complex, placing higher demands on the precision, efficiency, and safety of cable cutting operations.

[0003] Currently, the cutting tools used in the installation of high-voltage power cables are mainly divided into two categories: manual and electric. Among them, manual tools, such as cable knives and wire cutters, rely on the operator's manual force to apply cutting force. This not only results in high labor intensity and low work efficiency, but also makes it difficult to control the cutting accuracy. Problems such as uneven cuts, damage to the cable insulation layer, and conductor damage are prone to occur, which in turn affect the sealing performance of the cable joint and the reliability of the electrical connection, and may even cause safety hazards.

[0004] While existing electric cutting tools have reduced labor costs and improved work efficiency to some extent, they still have many technical shortcomings: First, the cutting length is inconvenient to adjust. Most devices cannot achieve precise positioning of the cutting length, requiring operators to rely on experience to judge, resulting in poor consistency in the length of cables installed in the same batch, increasing the difficulty of subsequent construction. Second, they lack adaptability. It is difficult to flexibly adjust the cutting depth to adapt to high-voltage cables of different diameters. For cables of different diameters, it is often necessary to replace the cutting head or the entire machine, increasing construction costs and preparation time. Third, the cutting pressure cannot be adjusted. It is impossible to adjust the cutting pressure according to the actual working conditions such as the thickness of the cable insulation layer and the hardness of the material. Excessive pressure can easily damage the cable conductor, while insufficient pressure may lead to incomplete cutting. Summary of the Invention

[0005] Therefore, the technical problem that this invention aims to solve is that it is not easy to adjust.

[0018] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0019] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0020] Reference Figures 1 to 5 This embodiment provides a high-voltage power cable installation tool, including a drive source 1. The drive source 1 has an output component 11 that can rotate to provide power. The output component 11 can transmit the rotational power generated by the drive source 1 to subsequent components to provide power for cable cutting operations. The device also includes a connector 2, which is detachably connected to the output component 11. When the output component 11 rotates, it can drive the connector 2 to rotate. The connector 2 is used as the power structure between the drive source 1 and the subsequent execution component, ensuring the stability of the power transmission process and avoiding power interruption or transmission deviation during operation.

[0021] The device also includes a slip ring 3, which forms a sliding fit structure with the connecting body 2. When the slip ring 3 slides along the axial direction of the connecting body 2, it can adjust the relative distance between itself and the connecting body 2. By adjusting this distance, the cutting length of the cable cutting operation can be directly controlled to meet the cable length cutting requirements under different installation scenarios. The device also includes a blade holder 4, which is mounted on a slip ring 3. The blade holder 4 can reciprocate along the radial direction of the slip ring 3. The radial movement allows for flexible adjustment of the cutting position of the blade 5 on the blade holder 4, thereby adapting to the cutting of high-voltage power cables of different diameters and improving the versatility of the tools. The slip ring 3 has a groove on its radial sidewall for the tool holder 4 to slide. In addition, a bolt-like structure can be provided at the axial end of the slip ring 3. By rotating the bolt-like structure, the bolt-like structure can be extended into the groove to lock the tool holder 4. This device also includes a blade 5, which is detachably mounted on the blade holder 4 for easy replacement and maintenance. The blade holder 4 is equipped with an adjustment component 6 and a pressure application component 7 corresponding to the mounting position of the blade 5. The pressure application component 7 can continuously apply cutting pressure to the blade 5 towards the cable, ensuring that the blade 5 is in close contact with the cable and the cutting force is uniform during the cutting process. The adjustment component 6 can adjust the pressure applied to the blade 5 by the pressure application component 7 through its own structural adjustment. The cutting pressure can be adjusted according to the insulation layer thickness and conductor material of the cable, so as to ensure cutting efficiency and avoid damage to the cable conductor due to excessive pressure or incomplete cutting due to insufficient pressure.

[0022] As an optional embodiment, the drive source 1 includes a drive motor 12. The drive motor 12 is selected to be a model suitable for the installation intensity of high-voltage cables and can output adjustable rotational power to meet the cutting power requirements under different working conditions. The output component 11 is the output shaft of the drive motor 12. The output shaft extends along the power output direction of the drive motor 12, and its end structure is adapted to the connection structure of the connector 2. It can directly form a stable connection with the connector 2 and can directly transmit the rotational power generated by the drive motor 12 to the connector 2, reducing the loss in the power transmission process.

[0023] As an optional embodiment, the connector 2 is provided with a connecting hole 21 corresponding to the installation position of the output component 11. The diameter and depth of the connecting hole 21 are adapted to the end size of the output component 11 to ensure the fit between the connector 2 and the output component 11. The connector 2 is fixedly connected to the output component 11 through the connecting hole 21. The connection method can adopt a stable connection form such as interference fit, key connection or threaded connection, which can effectively prevent relative rotation or axial displacement between the connector 2 and the output component 11 during operation.

[0024] Alternatively, a connecting column can be installed in the connecting hole 21 of the connecting body 2. The connecting column and the output component 11 are connected by a coupling, so that the rotational power of the output component 11 can be transmitted to the connecting body 2. When the output component 11 rotates, it can drive the connecting body 2 to rotate synchronously.

[0025] As an optional embodiment, a guide post 31 is integrally formed or fixedly installed on the side of the slip ring 3 facing the connecting body 2. The guide post 31 extends along the sliding direction of the slip ring 3. A guide hole 22 is opened on the connecting body 2 at the position corresponding to the guide post 31. The diameter of the guide hole 22 matches the outer diameter of the guide post 31, and the extending direction of the guide hole 22 is consistent with that of the guide post 31. The slip ring 3 forms a sliding connection with the connecting body 2 through the guide post 31 and the guide hole 22. This can limit the sliding trajectory of the slip ring 3, prevent the slip ring 3 from deviating or tilting when sliding, and ensure that the slip ring 3 moves smoothly in a preset direction, thereby enabling the adjustment of the distance between the slip ring 3 and the connecting body 2.

[0026] As an optional embodiment, the number of guide posts 31 is at least two, and the multiple guide posts 31 are evenly and symmetrically distributed along the circumference of the connecting body 2 to form a balanced guide support structure. The number of guide holes 22 corresponds one-to-one with the number of guide posts 31 and is precisely matched. Each guide hole 22 corresponds to only one guide post 31. This design of multiple sets of guide posts 31 and guide holes 22 can further improve the coaxiality and stability of the sliding fit between the slip ring 3 and the connecting body 2, effectively suppress the radial swing or tilting offset of the slip ring 3 during the sliding process, and ensure that the slip ring 3 always moves smoothly along the preset axial trajectory, providing a more reliable structural guarantee for the precise adjustment of the cutting length.

[0027] As an optional embodiment, the number of guide posts 31 is at least two. Multiple guide posts 31 are evenly and symmetrically distributed along the circumference of the connecting body 2 to form a balanced guide support structure. The number of guide holes 22 corresponds one-to-one with the number of guide posts 31 and is adapted accordingly. Each guide hole 22 is matched with only one guide post 31. The corresponding matching of multiple sets of guide posts 31 and guide holes 22 further improves the coaxiality and stability of the sliding fit between the slip ring 3 and the connecting body 2, suppresses the radial swing or tilting offset of the slip ring 3 during the sliding process, and ensures that the slip ring 3 always moves smoothly along the preset axial trajectory.

[0028] As an optional embodiment, threaded holes are provided on the connecting body 2 at positions corresponding to each guide hole 22. The positioning bolt 23 is installed in the connecting body 2 through the threaded holes and threadedly engaged. The axis of the positioning bolt 23 is perpendicular to the axis of the guide hole 22. When the positioning bolt 23 is rotated, its end can move along the axis of the threaded hole and extend into the guide hole 22, and closely abut against the outer circumferential surface of the guide post 31 to achieve positioning. By tightening the positioning bolt 23, the guide post 31 can be firmly locked in the target position of the guide hole 22, thereby fixing the relative distance between the slip ring 3 and the connecting body 2, effectively preventing the guide post 31 from sliding during the cutting operation, ensuring the stability of the cutting length. The positioning can be released by rotating the positioning bolt 23 in the opposite direction, making it easy to readjust the position of the slip ring 3.

[0029] As an optional embodiment, the blade holder 4 includes a cooperating end cap 41 and a housing 42. The end cap 41 and the housing 42 are detachably fixedly connected, which facilitates the subsequent installation and replacement of the blade 5 and the maintenance of the internal structure of the blade holder 4. The housing 42 forms an installation cavity that matches the shape of the blade 5. The blade 5 can be accurately embedded in the installation cavity for positioning. The housing 42 can wrap and protect the non-cutting edge part of the blade 5 to prevent the blade 5 from being damaged or shifted due to collision or friction during operation. The cutting edge of the blade 5 extends out from the housing 42. The extension length is adapted to the basic requirements of cable cutting, which ensures that the cutting edge can fully contact the cable to complete the cutting, while avoiding the safety hazards caused by excessive exposure of the cutting edge. At the same time, the edge of the housing 42 limits the extension of the cutting edge.

[0030] As an optional embodiment, an inner post 43 is integrally formed or fastened to the side of the end cap 41 facing the inside of the outer shell 42. The inner post 43 extends radially along the blade holder 4, and its axis is consistent with the moving direction of the blade 5. A sliding hole is opened on the blade 5 at the position corresponding to the inner post 43, which is precisely matched with the outer diameter of the inner post 43. The blade 5 forms a sliding connection with the inner post 43 through the sliding hole. This sliding fit structure can provide precise guidance and limit for the radial movement of the blade 5, ensuring that the blade 5 always moves smoothly along the preset radial trajectory and avoiding deviation and jamming during the movement of the blade 5.

[0031] As an optional embodiment, the pressure-applying component 7 is a spring, which is sleeved on the inner post 43 and located between the end cap 41 and the blade 5. The inner post 43 enables precise positioning, ensuring that the extension and contraction direction of the spring is consistent with the radial movement direction of the blade 5. One end of the spring is in close contact with the side of the blade 5 facing the end cap 41, and the other end is in contact with the end cap 41. The spring is in a pre-compressed state, which can continuously apply elastic pressure towards the cable to the blade 5, providing stable pressure support for the cutting of the blade 5. The inner post 43 is provided with an anti-detachment structure, which can be in the form of a limiting boss, a retaining ring, or a retaining ring. Specifically, it is set at the end of the inner post 43 away from the end cap 41, which can axially limit the sliding stroke of the blade 5, effectively preventing the blade 5 from detaching from the inner post 43 during the sliding process.

[0032] As an optional embodiment, the adjusting member 6 is a bolt structure with threads on its outer surface. The end cover 41 has an internal threaded hole corresponding to the installation position of the adjusting member 6. The specification of the internal thread is precisely matched with the external thread of the adjusting member 6 to ensure the sealing and stability of the threaded engagement. The adjusting member 6 is vertically installed on the end cover 41 through the threaded engagement, and its lower end extends into the housing 42 and is aligned with the upper end of the pressure member 7. When the adjusting member 6 is rotated, the self-locking characteristic of the threaded drive allows the adjusting member 6 to move smoothly up and down along the axial direction, thereby changing its length inside the housing 42. When the adjusting member 6 moves downward, it continuously presses the pressure member 7, increasing the compression of the spring and thus increasing the pressure applied to the blade 5. When the adjusting member 6 moves upward, the compression of the pressure member 7 decreases, and the pressure applied to the blade 5 decreases accordingly.

[0033] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
