Description

Technical Field

[0001] The invention relates to the technical field of electric machinery, in particular to a cable main insulation chamfering device. Background Art

[0002] With the development of economy and society and the increase of electricity users, the contradiction between infrastructure construction excavation and safe operation of cables is becoming increasingly fierce. The number and duration of power outages caused by external force damage to cables are increasingly concerned by more people, enterprises, and even the government. Therefore, the problem of reducing power outages due to faults needs to be solved urgently. In order to reduce power outages caused by external force damage to cables, the production time of our cable terminals and intermediate joints is required to be reduced, and the quality requirements are getting higher and higher. In the production process of cable terminals and intermediate joints, the chamfering of the main insulation layer of the cable is very important.

[0003] At present, chamfering is often done manually by production staff. The smoothness of the chamfer is limited by the on-site temperature and the skills of the construction workers. It is easy to have roughness, burrs, and even damage to the main insulation layer, cable head scrapping and other serious consequences. In the process of cable head production, a large number of problems were found because the chamfer of the main insulation of the cable did not meet the requirements, which laid hidden dangers for the later operation and maintenance of the cable. Therefore, how to effectively solve the problems of low compliance rate and low efficiency of existing cable chamfering has become an important issue.

[0004] In addition, the climate change is particularly obvious in Kuitun, Xinjiang, which leads to a significant problem, that is, the unstable quality control of manual chamfering. The climate conditions in Kuitun are changeable, with severe cold in winter and hot in summer. Such temperature differences have a significant impact on the thermal expansion and contraction characteristics of cable materials, making manual chamfering operations more challenging. The change in on-site temperature not only affects the operating feel of the construction workers, but also directly affects the smoothness and accuracy of the chamfering, often resulting in uneven chamfering and burrs. In severe cases, it even directly damages the main insulation layer of the cable, causing the cable head to be scrapped due to quality problems, increasing material costs and construction time.

[0005] In addition, the technical level of cable construction teams in Kuitun area is uneven, and the opportunities for professional training and skill improvement are limited, which makes it difficult to unify the technical standards of manual chamfering operations. Construction workers with different technical proficiency levels cannot ensure that the chamfer of each cable head meets the specified standards during chamfering operations, which leads to a series of quality problems. These quality problems not only reduce the efficiency of cable head production, but also seriously affect the safety and stability of cable lines, bringing many inconveniences and safety hazards to subsequent operation and maintenance.

[0006] Therefore, designing a cable main insulation chamfering device to solve the serious consequences of manual chamfering of cables, such as unevenness, burrs, and even damage to the main insulation layer and scrapping of the cable head, has become an urgent problem to be solved.

The staff can conveniently adjust the working parameters of the device by simply rotating the adjusting knob 5 without complicated operating steps; the intuitiveness and ease of operation of the adjusting knob 5 also reduce the skill requirements for the operator, allowing more staff to quickly get started and reduce training time and cost.

[0054] A guide shaft 40 is provided on the side of the guide screw 4. The guide shaft 40 and the guide screw 4 are parallel to each other. The guide shaft 40 connects the fixed plate 1 and the adjusting plate 2. The guide shaft 40 assists the guide screw 4 in connecting the fixed plate 1 and the adjusting plate 2 to prevent the adjusting plate 2 from tilting during the movement. The synergistic effect of the guide shaft 40 and the guide screw 4 also enhances the stability and reliability of the entire structure. The two jointly support and connect the fixed plate 1 and the adjusting plate 2 to form a stable frame, making the entire adjustment process smoother and safer.

[0055] A first fixing rod 41 is provided on the side of the guide shaft 40 close to the fixed plate 1. The diameter of the first fixing rod 41 is smaller than the diameter of the guide shaft 40.

A first latch 44 is connected inside the third connecting hole. Both ends of the first latch 44 extend out of the third connecting hole. The first latch 44 and the second fixing rod 43 are perpendicular. The adjusting knob 5 is fixed to the top of the second fixing rod 43 by the first latch 44. The adjusting knob 5 can be detached from the second fixing rod 43 by pulling out the second latch 39, and disassembly is simple and convenient.

[0057] A positioning tube 10 is provided on the top of the fixed plate 1, and the bottom of the cutter 33 extends into the interior of the positioning tube 10, and the outer side of the part of the cutter 33 extending into the positioning tube 10 is in contact with the side wall inside the positioning tube 10. The positioning tube 10 is used to position the cutter 33, thereby ensuring the stability and accuracy of the cutter 33 during operation, and effectively preventing the cutter 33 from shifting or shaking during the chamfering process.

[0058] The support seat and the fixing plate 1 are connected by a third screw 38. A threaded hole is provided at the bottom of the support seat 30, and a second connection hole is provided on the fixing plate 1. The third screw 38 passes through the second connection hole and extends into the inside of the threaded hole. By rotating the third screw 38, it can be firmly fixed in the threaded hole, thereby achieving the initial fixation between the support seat and the fixing plate 1. This connection method can resist certain external forces and maintain the stability of the structure. A second latch 39 is provided at the bottom of the support seat, and the other end of the second latch 39 extends into the inside of the fixing plate 1, further strengthening the connection between the support seat and the fixing plate 1. Fixing the support seat and the fixing plate 1 by the third screw 38 and the second latch 39 not only enhances the stability of the structure, but also effectively prevents loosening or detachment during use, and effectively determines the stability of the connection between the two.

[0059] The fixing plate 1 is provided with a first connection hole 11, and a connection ring 12 is provided in the first connection hole 11. The outer diameter of the connection ring 12 is consistent with the diameter of the first connection hole 11, and the inner diameter of the connection ring 12 is consistent with the diameter of the first fixing rod 41.

By providing the connection ring 12, the guide shaft 40 and the fixing plate 1 are fixedly connected, and the guide shaft 40 cannot extend out of the top of the fixing plate 1 or be separated from the fixing plate 1, thereby ensuring the stability of the connection between the fixing plate 1 and the guide shaft 40.

[0060] The adjustment plate 2 includes a first adjustment plate 20 and a second adjustment plate 21. The first adjustment plate 20 is parallel to the fixed plate 1. The second adjustment plate 21 adopts a "V"-shaped structure. When the cable terminal head and the intermediate joint are chamfered, the cable is placed on the second adjustment plate 21. The second adjustment plate 21 fixes the position of the cable to prevent the cable from shifting during the chamfering process.

[0061] A handle 14 is provided on the side of the fixing plate 1 , and a recessed structure that fits the fingers is provided on the outer side of the handle 14 , so that the staff can hold the handle 14 more comfortably and reduce fatigue during long-term operation.
