Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, specifically to a lifting and changing mechanism for cable feeding. Background Technology

[0002] As the carrier of electricity transmission, the safe operation and use of power cables is the responsibility of power and cable workers. Faults in medium- and high-voltage power cables can lead to large-scale power outages and economic losses. Therefore, quality inspection is a crucial step in ensuring cables are free of quality problems. Among these, the detection of micropores and impurities in the cable insulation layer is particularly important.

[0003] In the detection of micropore impurities in cable insulation, the cable after removing the copper core needs to be fed to a specified height for continuous slicing. In actual operation, after multiple slicings, the cable needs to be removed and re-clamped to expose the unsliced ​​parts. This step reduces work efficiency, so the tooling needs to be improved. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lifting and changing mechanism for cable feeding, thus solving the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting and changing mechanism for cable feeding, comprising an inner support chuck and an outer clamping chuck, wherein the inner support claws of the inner support chuck lift outward from the inside of the cable insulation layer to achieve clamping, and the outer clamping claws of the outer clamping chuck clamp the outside of the cable insulation layer inward.

[0006] The outer clamping chuck is fixedly installed on the upper platform, and the bottom of the inner support chuck is equipped with a lifting device to drive the inner support chuck to move up and down along the axial direction of the outer clamping chuck.

[0007] Preferably, the inner support chuck has a three-jaw structure, and the outer clamping chuck has a six-jaw structure.

[0008] Preferably, the inner support chuck is mounted on a lifting platform, and an axial retaining device is installed on the lifting platform to keep the inner support chuck and the outer clamping chuck relatively coaxial.

[0009] Preferably, the axial retaining device includes a base plate, an X-axis slide groove on the base plate, an adjusting plate slidably connected above the X-axis slide groove, a Y-axis slide groove on the adjusting plate, and a mounting plate slidably connected above the Y-axis slide groove. The mounting plate is used to fix the base of the inner support chuck.

[0010] The axial retaining device also includes a floating platform arranged around the base plate. The floating platform includes a base, on which a support shaft is horizontally slidably connected. A spring is sleeved on the support shaft, and the spring causes the support shaft to tend to extend toward one side of the base plate.

[0011] The floating platform is equipped with four sets of support shafts in the front, rear, left, and right directions. The support shafts of the front and rear sets abut against the outside of the mounting plate along the Y direction, while the support shafts of the left and right sets abut against the adjustment plate along the X direction.

[0012] In summary, this utility model has at least one of the following beneficial effects:

[0013] This utility model provides a lifting and changing mechanism for cable feeding, which improves detection efficiency, reduces labor costs and reduces the impact of human interference on measurement results, and avoids accuracy errors caused by secondary clamping. In actual implementation, laser lifting can be used for assistance, and the actual lifting accuracy can be controlled within ±0.01mm. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 A lifting and changing mechanism for cable feeding includes an inner support chuck 2 and an outer clamping chuck 1. The inner support jaws 21 of the inner support chuck 2 support the cable insulation layer from the inside out to achieve clamping, and the outer clamping jaws 11 of the outer clamping chuck 1 clamp the cable insulation layer from the outside in. The inner support chuck 2 has a three-jaw structure, and the outer clamping chuck 1 has a six-jaw structure.

[0019] The outer clamping chuck 1 is fixedly mounted on the upper platform 3. The bottom of the inner support chuck 2 is equipped with a lifting device 6, used to drive the inner support chuck 2 to move up and down along the axial direction of the outer clamping chuck 1. (Refer to...) Figure 1 and Figure 2 As shown, the lifting device 6 adopts a servo motor and reducer drive scheme, using a lead screw module for transmission. In practical applications, it can be combined with sensors and a servo control system to control the lifting accuracy.

[0020] The inner support chuck 2 and the outer clamping chuck 1 are aligned on the same axis. To maintain the coaxiality of the inner support chuck 2 and the outer clamping chuck 1, refer to... Figure 3As shown, the inner support chuck 2 is mounted on the lifting platform 5, and the lifting platform 5 is equipped with an axial retaining device 4 to keep the inner support chuck 2 and the outer clamping chuck 1 relatively coaxial. The axial retaining device 4 includes a base plate 44, on which an X-direction slide groove is provided. An adjusting plate 45 is slidably connected above the X-direction slide groove. A Y-direction slide groove is provided on the adjusting plate 45, and a mounting plate 41 is slidably connected above the Y-direction slide groove. The mounting plate 41 is used to fix the base of the inner support chuck 2.

[0021] The axial retaining device 4 also includes a floating platform disposed around the base plate 44. The floating platform includes a base 42, on which a support shaft 43 is horizontally slidably connected. A spring is sleeved on the support shaft 43, and the spring causes the support shaft 43 to tend to extend toward one side of the base plate 44. As shown in the figure, the front end of the support shaft 43 is provided with an outwardly protruding annular abutment surface. The radius of the spring itself is larger than the radius of the connection hole through which the support shaft 43 passes through the base 42. Therefore, the spring is located between the connection hole and the abutment surface, providing elastic force for the support shaft 43.

[0022] The floating platform has four sets of support shafts 43 arranged in the front, rear, left, and right directions. The support shafts 43 of the front and rear sets abut against the outside of the mounting plate 41 along the Y direction, while the support shafts 43 of the left and right sets abut against the adjusting plate 45 along the X direction. The spring-loaded support shafts 43 provide support in four directions to ensure the designed position of the inner support chuck 2, that is, its coaxial position with the outer clamp chuck 1.

[0023] In practical use, the cable with the copper core ejected is manually placed on the chuck, and the outer clamping jaws 11 clamp inward, while the inner support jaws 21 open to provide internal support. When it is necessary to adjust the cable extension height, the inner support jaws 21 maintain the clamped state, the outer clamping jaws 11 loosen, the inner support jaws 21 rise to the designated height, the outer clamping jaws 11 clamp again, and the inner support jaws 21 descend back to the initial position and open again, completing the lifting and hand-changing operation. This mechanism can maintain the cable clamped state, ensuring the cable is lifted and lowered vertically.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
