Description

Technical Field

[0001] The invention relates to the technical field of cable cutting devices, in particular to a reaction force cone cutting device. Background Art

[0002] High-voltage direct current transmission has the advantages of high transmission efficiency and low energy loss. Because it is more economical than AC transmission, it is widely used in long-distance or ultra-long-distance transmission. However, due to the limitations of high-voltage cable manufacturing technology, the maximum length of jointless manufacturing is 10km. When ultra-long-distance transmission is to be achieved, the single cable joint needs to be processed so that multiple cables can be spliced ​​together. At the cable joint, due to the two different insulating materials of the cable body insulation and the additional insulation, its electric field distribution is different from that of the cable body, which causes a certain potential difference between two adjacent points on the same layer of insulation, that is, the axial field strength, that is, the axial stress.

[0003] Therefore, the insulation layer near the conductor connection end is usually cut into a conical surface, namely the reaction cone, and then wrapped with additional insulation to form stress cone surfaces at both ends of the additional insulation. In the cable reaction cone manufacturing process, it is required to strip the insulation layer at the end of the core and cut the "pencil head". In actual operation, the cut cone surface should be complete, uniform and symmetrical, and the blade should not scratch the conductor during cutting.

[0004] In the prior art, a universal automatic cable stripper is often used to strip cables of 35 kV and above to form a reaction force cone. However, the actual size of each cable core is different, and the actual size deviates from the standard size. The universal automatic cable stripper directly cuts the cable according to the standard size, which can easily damage the cable conductor, or cause problems such as incomplete cutting of the cable conductor surface, leaving insulation marks, and poor molding quality. Summary of the invention

[0036] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0037] This embodiment provides a reaction force cone cutting device, which can cut according to the actual thickness between the cable conductor and the cable skin, can avoid damaging the cable conductor, incomplete cutting of the cable conductor surface, and leaving insulation marks, and has good molding quality.

[0038] like Figure 1-Figure 4As shown, the reaction force cone cutting device provided in this embodiment includes a clamping mechanism 1, a cutting tool 2 and a sensor module (not shown in the figure). Specifically, the clamping mechanism 1 includes a first clamping seat 11 and a second clamping seat 12 arranged opposite to each other, and a clamping space (not shown in the figure) for clamping the cable 100 is formed between the first clamping seat 11 and the second clamping seat 12, which is used to install the reaction force cone cutting device on the cable 100. The cutting tool 2 is adjustably connected to the first clamping seat 11 along its axial position, and the cutting end 21 of the cutting tool 2 is located in the clamping space, and the cutting end 21 has a horizontal cutting surface 211 and a first inclined cutting surface 212 arranged at an angle to the horizontal cutting surface 211, and the horizontal cutting surface 211 and the first inclined cutting surface 212 are connected to form a cutting edge for cutting the cable 100. The sensor module includes a first displacement sensor, which is used to measure the moving distance of the cutting tool 2 along its axial direction. When the clamping mechanism 1 rotates around the axis of the cable 100, the cutting edge can cut the cable 100, and the first inclined cutting surface 212 interacts with the cable 100 to move the clamping mechanism 1 relative to the cable 100 on the axis of the cable 100 by a preset length, so as to form a complete cone surface during the cutting process. It can be understood that when the reaction force cone cutting device is used to cut the cable 100, it is necessary to complete the cutting twice. For the first cutting, the reaction force cone cutting device is first installed on the cable 100, that is, the clamping mechanism 1 clamps the cable 100, and adjusts the position of the cutting tool 2 along its axial direction, so that the cutting edge contacts the cable skin (not shown in the figure), and the tool is set. Then adjust the depth of the cutting tool 2, and drive the clamping mechanism 1 to rotate around the axis of the cable 100 for one circle, and then repeat the operation steps until the cutter cuts the cable conductor (not shown in the figure), and then obtain the moving distance of the cutting tool 2 along its axial direction, that is, the actual thickness between the cable conductor and the cable skin through the first displacement sensor. In the second cutting, after obtaining the actual thickness, the data of each adjustment of the depth of the cutting tool 2 and the number of rotations are determined, and then the reaction force cone cutting device is moved to the preset position to complete the tool setting operation, and then the depth of the cutting tool 2 is adjusted according to the data of each adjustment of the depth of the cutting tool 2, and the clamping mechanism 1 is driven to rotate around the axis of the cable 100 for one circle, and then the operation steps are repeated until the corresponding number of rotations is completed to complete the processing of the reaction force cone, that is, the reaction force cone cutting device can be used to cut according to the actual thickness between the cable conductor and the cable skin, which can avoid damaging the cable conductor, incomplete cutting of the cable conductor surface, and leaving insulation marks, and the molding quality is better. It should be noted that the number of rotations required for the reaction force cone cutting device can be calculated based on the actual thickness obtained and the depth of each adjustment of the cutting tool 2 during the first cutting. For example, the value obtained by dividing the actual thickness by the depth of each adjustment of the cutting tool 2 is the number of rotations required for the reaction force cone cutting device to complete the reaction force cone production.

[0039] Furthermore, the sensor module also includes a second displacement sensor (not shown in the figure), which is used to measure the moving distance of the first clamping seat 11 along the axial direction of the cable 100. It can be understood that by setting the second displacement sensor to measure the moving distance of the first clamping seat 11 along the axial direction of the cable 100, that is, the moving distance of the reaction force cone cutting device along the axial direction of the cable 100, the height of the reaction force cone to be formed by cutting the cable 100 along the axial direction of the cable 100 can be obtained, which is convenient for comparing whether the size of the reaction force cone obtained by the final processing is the preset size. As for the specific structure of the first displacement sensor and the second displacement sensor, it is a prior art, and this embodiment does not make specific limitations on this.

[0040] Furthermore, if Figure 1-Figure 2 As shown, the first clamping seat 11 is provided with a fixing assembly 111 and a fixing hole 112 extending along the axial direction of the cutting tool 2, and the cutting tool 2 is provided with an external threaded portion 22, which is penetrated through the fixing assembly 111 and the fixing hole 112 and is screwed with the fixing assembly 111. It can be understood that the fixing assembly 111 cooperates with the fixing hole 112, and on the basis of realizing the axial movement of the cutting tool 2, the fixing assembly 111 is used to adjust the position of the cutting tool 2 to the first clamping seat 11, thereby meeting the use requirement of adjusting the depth of the cutting tool 2 during use.

[0041] Further, continue to refer to Figure 1-Figure 2 The fixing assembly 111 includes a first fixing member 1111 and a second fixing member 1112 symmetrically arranged relative to the fixing hole 112 in the axial direction of the cutting tool 2, and threads matching with the external threaded portion 22 are arranged in the first fixing member 1111 and the second fixing member 1112. It can be understood that the external threaded portion 22 is fixed by the first fixing member 1111 and the second fixing member 1112. When the position of the cutting tool 2 needs to be adjusted, the first fixing member 1111 and the second fixing member 1112 are rotated to make the first fixing member 1111 and the second fixing member 1112 move in relatively distant directions respectively, and then the position of the cutting tool 2 is adjusted. After the adjustment, the first fixing member 1111 and the second fixing member 1112 are rotated to make the first fixing member 1111 and the second fixing member 1112 move in relatively close directions respectively, until the first fixing member 1111 and the second fixing member 1112 are respectively abutted against the first clamping seat 11 to fix the cutting tool 2.

[0042] Exemplarily, the first fixing member 1111 and the second fixing member 1112 are both external hexagonal nuts, which facilitates an operator to drive the first fixing member 1111 and the second fixing member 1112 to rotate.

[0043] Furthermore, if Figure 3-Figure 4As shown, the cutting end 21 also has a second inclined cutting surface 213, and the second inclined cutting surface 213 is set at an angle with the first inclined cutting surface 212 and the horizontal cutting surface 211. It can be understood that by setting the second inclined cutting surface 213, it is ensured that the cutting tool 2 and the cut part of the cable 100 will not interfere with each other, avoiding the cutting tool 2 from damaging the surface quality of the cut cable 100, and ensuring the normal movement of the cutting tool 2 during the cutting process, with high fluency, and improving the surface quality of the reaction force cone.

[0044] Furthermore, if Figure 2 As shown, the clamping mechanism 1 also includes an adjusting component 13, which is driven and connected to the second clamping seat 12 and is used to adjust the distance between the second clamping seat 12 and the first clamping seat 11. It can be understood that by setting the adjusting component 13 to be driven and connected to the second clamping seat 12, the distance between the second clamping seat 12 and the first clamping seat 11 can be adjusted, which is convenient for operators to install the reaction force cone cutting device on the cable 100, or remove it from the processed cable 100, which is convenient for disassembly and assembly, and at the same time, the degree of tightness of the clamping mechanism 1 on the cable 100 can be adjusted, and the clamping requirements of the cable 100 can be met for cables 100 of different sizes, and the applicability is strong.

[0045] For example, Figure 2 As shown, multiple groups of adjustment components 13 are arranged at intervals, and each group of adjustment components 13 includes an adjustment nut 131 and an adjustment bolt 132. The adjustment bolt 132 is passed through the first clamping seat 11 and the second clamping seat 12. The nut of the adjustment bolt 132 abuts against the side of the second clamping seat 12 facing away from the first clamping seat 11, and the threaded end of the adjustment bolt 132 cooperates with the adjustment nut 131. The adjustment nut 131 abuts against the side of the first clamping seat 11 facing away from the second clamping seat 12. It can be understood that by providing the adjusting nut 131 and the adjusting bolt 132, under the premise that the second clamping seat 12 can move relative to the first clamping seat 11, the adjusting nut 131 and the adjusting bolt 132 can cooperate stably, and the stability of the first clamping seat 11 and the second clamping seat 12 in clamping the cable 100 can be improved. In addition, the adjusting nut 131 and the adjusting bolt 132 can cooperate to achieve fine-tuning of the relative position of the first clamping seat 11 and the second clamping seat 12. Compared with other types of adjustment components 13, it is easy to control the adjustment size and improve the adjustment accuracy.

[0046] Furthermore, the outer surface of the adjusting nut 131 is provided with vertical lines (not shown in the figure), which increases the friction force when the operator rotates the adjusting nut 131, making it easier for the operator to drive the adjusting nut 131 to rotate.

[0047] It is further conceivable that by providing multiple groups of spaced adjustment components 13, the stability of the first clamping seat 11 and the second clamping seat 12 in clamping the cable 100 is improved, and the multiple groups of adjustment components 13 work together to guide the movement of the second clamping seat 12 relative to the first clamping seat 11, thereby preventing the second clamping seat 12 from deviating or misaligning. For example, the number of adjustment components 13 can be 2, 4, 6, etc. In this embodiment, the number of adjustment components 13 is 4 groups. Of course, in other embodiments, the number of adjustment components 13 can also be other numbers. The specific number of adjustment components 13 can be determined according to actual use requirements.

[0048] Furthermore, the adjustment assembly 13 also includes an elastic member (not shown in the figure), which is sleeved on the adjustment bolt 132, and the two ends of the elastic member are respectively in contact with the first clamping seat 11 and the second clamping seat 12. It can be understood that when the first clamping seat 11 and the second clamping seat 12 clamp the cable 100, the elastic member is in a compressed state. After the reaction force cone is processed on the cable 100, the adjustment nut 131 is driven to rotate. When the clamping of the cable 100 is released, the elastic force of the elastic member can be relied on to drive the second clamping seat 12 to move away from the first clamping seat 11, and the clamping of the first clamping seat 11 and the second clamping seat 12 on the cable 100 is quickly released, and the operation process is smooth. Exemplarily, the elastic member is a spring, which is sleeved on the adjustment bolt 132.

[0049] Furthermore, if Figure 2 As shown, the clamping mechanism 1 also includes a roller assembly (not shown in the figure), the roller assembly includes a plurality of rollers 14, and the rollers 14 are both provided on the side of the first clamping seat 11 facing the second clamping seat 12 and the side of the second clamping seat 12 facing the first clamping seat 11, and the axial directions of the plurality of rollers 14 are configured to be parallel to the axial direction of the cable 100, and the plurality of rollers 14 are used to roll and support the cable 100. It can be understood that the axial directions of the plurality of rollers 14 are parallel to the axial direction of the cable 100, and when the cable 100 is clamped, the clamping mechanism 1 can rotate around the cable 100 more smoothly, thereby improving the smoothness and stability of the clamping mechanism 1 rotating around the cable 100, thereby improving the stability of the rotation of the cutting tool 2, and improving the surface quality of the reaction force cone.

[0050] Furthermore, the first clamping seat 11 and the second clamping seat 12 are both provided with a V-shaped groove (not shown in the figure), and the two V-shaped grooves cooperate with each other to form a clamping space. The side wall of the V-shaped groove is provided with an avoidance groove (not shown in the figure) corresponding to the roller 14, and at least part of the roller 14 is movably arranged in the corresponding avoidance groove. It can be understood that the provision of the V-shaped groove facilitates the alignment of the first clamping seat 11 and the second clamping seat 12 with the cable 100. The roller 14 is arranged on the groove side of the V-shaped groove. In the radial direction of the cable 100, the distance between different rollers 14 on the same clamping seat can be appropriately increased, and the relative distance between the roller 14 on the first clamping seat 11 and the roller 14 on the second clamping seat 12 can be reduced. On the basis that the cable 100 does not abut against the groove wall of the V-shaped groove, multiple rollers 14 are evenly spaced, which improves the rotation stability of the clamping mechanism 1. Furthermore, at least part of the roller 14 is movably disposed in the corresponding avoidance groove, so that the roller 14 is prevented from occupying too much space in the clamping space, thereby ensuring the size of the clamping space and improving the applicability of the clamping mechanism 1 .

[0051] Furthermore, if Figure 3 As shown, multiple rollers 14 located on the same groove wall of the V-shaped groove are coaxially arranged. It can be understood that, by utilizing the circumferential movement of the rollers 14 along the cable 100, the coaxial arrangement of multiple rollers 14 on the same groove wall is conducive to improving the balance of the rotation of the clamping mechanism 1 relative to the axis of the cable 100, and the clamping mechanism 1 operates more stably during the rotation process.

[0052] It should be noted that the roller assembly may include 8, 12, 16 or other number of rollers 14. In the present embodiment, the roller 14 is a bearing, and the roller assembly includes 8 rollers 14. Two rollers 14 located on the same groove wall of the V-shaped groove are coaxially arranged, which not only satisfies the requirement of stable support for the cable 100, but also avoids too many rollers 14 occupying too much clamping space.

[0053] Furthermore, if Figure 1-Figure 2 As shown, the first clamping seat 11 and / or the second clamping seat 12 are connected to a driving rod 15. It is understandable that when the operator drives the driving rod 15 to rotate, the entire reaction force cone cutting device can be driven to rotate to complete the cutting of the cable 100, which is convenient to operate and labor-saving.

[0054] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
