Description

Technical Field

[0001] This invention relates to the field of power engineering technology, and in particular to a circumferential cutting tool and a cutting method for corrugated aluminum sheaths. Background Technology

[0002] Metal sheaths are an essential part of high-voltage cable structures, and corrugated aluminum sheaths are widely used due to their high mechanical strength and good lightning protection. However, in daily power system operation and maintenance, corrugated aluminum sheaths sometimes crack and get damaged, requiring removal and replacement.

[0003] Because the corrugated aluminum sheath is spirally corrugated, cutting a single turn radially perpendicularly can easily damage the water-blocking layer inside the sheath and the outer semi-conductive shielding layer, and may also damage the cable, leading to short circuits and leakage in the circuit system. Existing corrugated pipe cutting machines use photoelectric sensors to detect the crest position of the corrugated pipe and cut at that position to ensure its internal structure is not damaged. However, this device is complex in structure and expensive, making it unsuitable for large-scale deployment. Summary of the Invention

[0004] The purpose of this invention is to provide a cutting method for a circumferential cutting tool and a corrugated aluminum sleeve, which can perform rotary cutting on the crest of the corrugated aluminum sleeve, ensuring that its internal structure is not damaged, and is low in cost and can be widely used.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0022] Driven by the rotating mechanism, the gear mechanism drives the clamping assembly to rotate relative to the corrugated aluminum sheath via the connecting mechanism.

[0023] As an optional solution for the circumferential cutting tool, the gear mechanism includes a driving gear and a driven gear. The driving gear is connected to the output end of the rotating mechanism and meshes with the driven gear. The driven gear is rotatably fitted onto the corrugated aluminum sleeve and connected to the first end of the connecting mechanism. The driven gear rotates under the drive of the rotating mechanism and drives the clamping assembly to rotate around the corrugated aluminum sleeve through the connecting mechanism.

[0035] This invention provides a circumferential cutting tool and a cutting method for corrugated aluminum sleeves. The circumferential cutting tool includes a clamping assembly, a positioning assembly, a cutting blade, and a driving assembly. The clamping assembly includes a first clamping plate and a second clamping plate, which are used to clamp a corrugated aluminum sleeve extending along a first direction. The positioning assembly includes a positioning ball, guide wheels, and a guide ring. The positioning ball is disposed on the first clamping plate and abuts against the first trough of the corrugated aluminum sleeve to initially position the sleeve. Two guide wheels are provided, both disposed on the second clamping plate and adjustable in position along both the first and second directions.

[0061] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0062] Example 1

[0063] like Figures 1 to 10 As shown, the present invention provides a circumferential cutting tool, including a clamping assembly 1, a positioning assembly 2, a cutting blade 3, and a driving assembly 4. The clamping assembly 1 includes a first clamping plate 11 and a second clamping plate 12, which clamp the first clamping plate 11 and the second clamping plate 12 on both sides of a corrugated aluminum sheath 100 extending along a first direction, and the spacing between them along a second direction is adjustable. The positioning assembly 2 includes a positioning ball 21, a guide wheel 22, and a guide ring 23. The positioning ball 21 is disposed on the first clamping plate 11 and abuts against the first trough 101 of the corrugated aluminum sleeve 100 for initial positioning of the corrugated aluminum sleeve 100. Two guide wheels 22 are provided, each disposed on the second clamping plate 12, and their positions are adjustable along both the first and second directions. The two guide wheels 22 are used to abut against the second trough 102 and the third trough 103 of the corrugated aluminum sleeve 100 respectively. The guide ring 23 is adjustablely disposed on the first clamping plate 11 along the second direction and abuts against the first crest 104. The cutting blade 3 is adjustablely disposed on the first clamping plate 11 along the second direction and abuts against the second crest 105. Driven by the drive component 4, the clamping component 1 can rotate relative to the corrugated aluminum sleeve 100. During the rotation, under the positioning and guiding function of the positioning component 2, the cutting blade 3 can accurately cut the second wave crest 105, protecting its internal structure from damage. In addition, the cutting tool is made of simple and readily available materials, has low cost, and has good practicality.

[0064] Specifically, such as Figure 2 The corrugated aluminum sheath 100 shown has a second trough 102, a first trough 101, and a third trough 103 arranged sequentially along a first direction. A first peak 104 is located between the second trough 102 and the first trough 101, and a second peak 105 is located between the first trough 101 and the third trough 103. That is, for the second peak 105 to be cut, its adjacent peaks and troughs are precisely positioned to ensure that the cutting blade 3 can always travel and cut along the second peak 105, avoiding deviation of the cutting blade 3.

[0065] Optionally, such as Figure 3 and Figure 4As shown, the second clamping plate 12 has two first strip grooves 120 spaced apart along the first direction. A slide rod 121 is threaded through each first strip groove 120. A guide wheel 22 is connected to the end of the slide rod 121 near the corrugated aluminum sleeve 100. The position of the slide rod 121 within the first strip groove 120 can move along the first direction to align the guide wheel 22 with the trough of the corrugated aluminum sleeve 100. Two fixing nuts 122 are threaded onto the slide rod 121, and the two fixing nuts 122 are located on opposite sides of the second clamping plate 12. Adjusting the position of the fixing nuts 122 on the slide rod 121 allows for adjustment of the slide rod 121's position along the second direction, thereby pressing the guide wheel 22 against the trough. This design is suitable for corrugated aluminum sleeves 100 with different corrugation spacings.

[0066] Specifically, a mounting bracket is provided on the slide bar 121, and the guide wheel 22 is mounted on the mounting bracket, facilitating future maintenance and replacement of the guide wheel 22. Furthermore, the guide wheel 22 is movable relative to the mounting bracket, and the troughs on the corrugated aluminum sleeve 100 extend spirally in the first direction. When the clamping assembly 1 rotates relative to the corrugated aluminum sleeve 100, the guide wheel 22 rolls along the corresponding troughs. During this rolling motion, the guide wheel 22 adapts to the rotation relative to the mounting bracket, ensuring that the guide wheel 22 remains within the troughs of the corrugated aluminum sleeve 100 without jamming.

[0067] Optionally, the circumferential cutting tool also includes two retaining rods 112. For example... Figure 5 As shown, a mounting base 110 is provided on the first clamping plate 11. Two mounting slots 111 are formed on the mounting base 110, extending through the first clamping plate 11. Two fixing rods 112 correspondingly pass through the two mounting slots 111 and are movable within their respective slots. One of the fixing rods 112 is equipped with a cutting blade 3, and the other with a guide ring 23. Each fixing rod 112 has an abutment surface 1120. A screw 113 extending in a second direction is screwed onto the mounting base 110 corresponding to each mounting slot 111. A portion of the screw 113 extends into the mounting slot 111 and abuts against the abutment surface 1120. By turning the screw 113, the screw 113 can be moved in the second direction, and then the fixed rod 112 can be pushed to move in the second direction by pushing against the contact surface 1120, so that the guide ring 23 is pressed against the first wave crest 104 and the cutting blade 3 is pressed against the second wave crest 105.

[0068] Specifically, in this embodiment, the fixing rod 112 has a groove at one end that passes through the mounting slot 111. A first fastener is inserted into each of the two grooves. The cutting blade 3 and the guide ring 23 are rotatably connected to the grooves of the fixing rod 112 via the first fasteners. The two ends of the first fasteners are respectively connected to the two opposite inner walls of the grooves, and the cutting blade 3 and the guide ring 23 are rotatably engaged with their respective first fasteners. The grooves provide a mounting base for the cutting blade 3 and the guide ring 23. For example, the first fastener may be a pin or similar component.

[0069] Specifically, in this embodiment, referring to Figure 3 The screw 113 is provided with a screwing part at the end away from the mounting groove 111. The screwing part is located on the side of the fixing rod 112 away from the first clamping plate 11, which makes it easy to screw the screw 113.

[0070] Optionally, the clamping assembly 1 further includes a fastening bolt 116 extending along the first direction, such as... Figure 3 and Figure 4 As shown, a first plate 114 protrudes from one end of the first clamping plate 11 facing the second clamping plate 12, and a second plate 123 protrudes from one end of the second clamping plate 12 facing the first clamping plate 11. A fastening bolt 116 passes through the first plate 114 and the second plate 123. At least one of the first plate 114 and the second plate 123 is provided with a second slot 115 extending in a second direction. The fastening bolt 116 is located within the second slot 115, and its relative position within the second slot 115 is adjustable to adjust the distance between the first clamping plate 11 and the second clamping plate 12 along the second direction.

[0071] For example, in this embodiment, there are two first plates 114 and two second plates 123 spaced apart along the first direction, and the two first plates 114 and two second plates 123 are staggered to ensure the stability when the distance between the first clamping plate 11 and the second clamping plate 12 is adjusted.

[0072] Optionally, refer to Figure 1 The drive assembly 4 includes a rotating mechanism 41, a gear mechanism 42, and a connecting mechanism 43. The rotating mechanism 41 is connected to the first end of the connecting mechanism 43 via the gear mechanism 42, and the second end of the connecting mechanism 43 is connected to the clamping assembly 1. Driven by the rotating mechanism 41, the gear mechanism 42 drives the clamping assembly 1 to rotate relative to the corrugated aluminum sleeve 100 via the connecting mechanism 43, thereby performing circumferential cutting on the corrugated aluminum sleeve 100.

[0073] For example, the rotating mechanism 41 is a commonly used driving device in the art, such as an electric motor or hydraulic motor, as long as it can drive the drive gear 421 to rotate, and no specific limitation is made here.

[0074] Furthermore, such as Figure 6 and Figure 7 As shown, the gear mechanism 42 includes a driving gear 421 and a driven gear 422. The driving gear 421 is connected to the output end of the rotating mechanism 41 and meshes with the driven gear 422. The driven gear 422 is rotatably fitted onto the corrugated aluminum sleeve 100 and connected to the first end of the connecting mechanism 43. The driven gear 422 rotates under the drive of the rotating mechanism 41 and drives the clamping assembly 1 to rotate around the corrugated aluminum sleeve 100 through the connecting mechanism 43.

[0075] Specifically, in this embodiment, the number of teeth of the driving gear 421 is less than the number of teeth of the driven gear 422. This saves space while achieving speed reduction and increasing the transmitted torque, preventing the clamping assembly 1 from rotating too quickly relative to the corrugated aluminum sleeve 100 and damaging the cutting blade 3, thus improving the circumferential cutting quality. It also provides a larger torque to ensure stable rotation of the clamping assembly 1. Additionally, referring to... Figure 9 The driven gear 422 includes two separate gear pieces, each of which is semi-circular and connected to the first clamping plate 11 and the second clamping plate 12 respectively through a connecting rod structure 431, so that it can be fitted onto the corrugated aluminum sheath 100, making the operation simpler and more convenient.

[0076] Furthermore, continue to refer to Figure 6 and Figure 7 A retaining ring 423 protrudes from the side of the driven gear 422 near the clamping assembly 1. The retaining ring 423 is sleeved on the corrugated aluminum sleeve 100 and can rotate relative to the corrugated aluminum sleeve 100. The connecting mechanism 43 includes two connecting rod structures 431, which are respectively disposed on opposite sides of the retaining ring 423. The end of the connecting rod structure 431 away from the retaining ring 423 is connected to the clamping assembly 1 and is adjustable in a fixed position along the first direction.

[0077] Specifically, in this embodiment, two connecting rod structures 431 are connected one-to-one with the first clamping plate 11 and the second clamping plate 12 to transmit the power from the driven gear 422 to the clamping assembly 1, so that the clamping assembly 1 rotates synchronously. Moreover, the arrangement of the two connecting rod structures 431 can ensure that the clamping assembly 1 is subjected to balanced force.

[0078] Furthermore, the connecting rod structure 431 has a third strip-shaped groove 432 extending along the first direction. A second fastener passes through the third strip-shaped groove 432 and is connected to the corresponding first clamping plate 11 or second clamping plate 12. The position of the second fastener within the third strip-shaped groove 432 is adjustable to adjust the fixed position of the connecting rod structure 431 and the clamping assembly 1, making the position of the clamping assembly 1 relative to the gear mechanism 42 in the first direction adjustable, which facilitates the guide wheel 22 engaging into the corresponding trough. For example, the second fastener is a bolt, nut, or screw.

[0079] In this embodiment, one of the linkage structures 431 includes two connected links. In other embodiments, the number of links in the linkage structure 431 can be adjusted as needed.

[0080] Optionally, such as Figure 7 and Figure 8 As shown, a groove 424 is recessed along the circumference on the side of the driven gear 422 facing away from the clamping assembly 1. A sliding member 411 is provided on the rotating mechanism 41. The sliding member 411 is slidably disposed in the groove 424, which can ensure the stability of the driven gear 422 during rotation.

[0081] In this embodiment, as Figure 9 and Figure 10 As shown, the cross-section of the slide groove 424 is L-shaped. Correspondingly, one end of the sliding member 411 that extends into the slide groove 424 is provided with a protrusion to be engaged within the slide groove 424, further improving the stability of the driven gear 422 during rotation. In addition, a reinforcing structure is provided at the connection between the rotating mechanism 41 and the sliding member 411 to improve their connection strength.

[0082] Optionally, such as Figure 6 and Figure 7 As shown, an annular groove 425 is provided in the driven gear 422, and a flexible structure is provided in the annular groove 425. The flexible structure slides in contact with the outer surface of the corrugated aluminum sheath 100 to prevent scratches on the corrugated aluminum sheath 100 and provides a certain degree of protection.

[0083] For example, the flexible structure can be epoxy soft rubber, which can wrap the corrugated aluminum sheath 100 with a certain force while preventing damage to its surface.

[0084] This embodiment also provides a cutting method for the corrugated aluminum sheath 100, applied to the above-mentioned circumferential cutting tool, including the following steps:

[0085] S1: Place the corrugated aluminum sheath 100 between the first clamping plate 11 and the second clamping plate 12, and make the positioning ball 21 press against the first trough 101;

[0086] The above steps involve using the positioning ball 21 to initially position the corrugated aluminum sheath 100.

[0087] S2: The first clamping plate 11 and the second clamping plate 12 clamp the corrugated aluminum sheath 100;

[0088] Specifically, in this embodiment, the above steps involve adjusting the position of the fastening bolt 116 in the second groove 115 and locking the first plate 114 and the second plate 123 with the fastening bolt 116 to achieve clamping and fixing of the corrugated aluminum sheath 100.

[0089] S3: Adjust the two guide wheels 22 along the first and second directions so that they are respectively pressed against the second trough 102 and the third trough 103;

[0090] Specifically, in this embodiment, the above steps involve adjusting the position of the slide bar 121 within the first groove 120 to achieve position adjustment in the first direction, and then adjusting the position of the fixing nut 122 on the slide bar 121 to achieve position adjustment in the second direction, so that the two guide wheels 22 are respectively pressed against the second trough 102 and the third trough 103.

[0091] S4: Adjust the guide ring 23 and the cutting blade 3 along the second direction so that they are respectively pressed against the first wave crest 104 and the second wave crest 105;

[0092] In this specific embodiment, the above steps can be achieved by turning the screw 113 to drive the fixing rod 112 to approach the corrugated aluminum sleeve 100 along the second direction, so that the guide ring 23 and the cutting blade 3 are respectively pressed against the first wave crest 104 and the second wave crest 105.

[0093] S5: Drive assembly 4 drives clamping assembly 1 to rotate relative to corrugated aluminum sheath 100 so that cutting blade 3 circumferentially cuts the second crest 105 of corrugated aluminum sheath 100.

[0094] In this specific embodiment, the above steps involve driving the gear mechanism 42 to rotate under the drive of the rotating component, and driving the clamping component 1 to rotate relative to the corrugated aluminum sheath 100 through the connecting mechanism 43, thereby completing the circumferential cutting of the second wave crest 105.

[0095] Example 2

[0096] Based on the same inventive concept as Embodiment 1, this embodiment provides a circumferential cutting tool, which differs from Embodiment 1 in that:

[0097] In this embodiment, the adjustment method of the first clamping plate 11 and the second clamping plate 12 is as follows: A linear drive mechanism is provided on the first clamping plate 11, the housing of the linear drive mechanism is fixed to the first clamping plate 11, and the telescopic rod of the linear drive mechanism is fixedly connected to the second clamping plate 12. The telescopic rod can extend and retract relative to the housing in the second direction. When the telescopic rod extends and retracts relative to the housing, the distance between the first clamping plate 11 and the second clamping plate 12 can be adjusted to realize the automation and intelligence of the adjustment, making the operation simpler and more convenient, and improving the work efficiency.

[0098] For example, the linear drive mechanism is a pneumatic cylinder, hydraulic cylinder, or electric actuator, etc.

[0099] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
