Description

Technical Field

[0001] This invention relates to the field of cable construction equipment technology, specifically to a cable cutting device for cable wells. Background Technology

[0002] In the construction of power cable laying projects, cable wells, as key nodes for cable transfer and branching, often require the cutting and stripping of already laid cables to facilitate subsequent cable splicing and wiring operations. Currently, traditional cable cutting operations mostly rely on manual hand-held cutting tools or simple cutting devices for step-by-step processing, which has several drawbacks: Firstly, cables are generally heavy and bulky, making it extremely inconvenient to move them manually to the cutting position. Furthermore, the interior space of cable wells is narrow and the working environment is complex, making direct cutting from the ground unsuitable for underground operations. Secondly, the existing cutting device has a single function, which can only cut cables. The stripping and surface cleaning after cutting need to be completed separately with the help of other tools. The operation process is cumbersome, time-consuming and labor-intensive, and the connection between the steps is not smooth, which affects the operation efficiency. Third, during manual operation, the cable positioning is not secure, which can easily lead to problems such as cutting deviation, uneven stripping, and residual impurities on the surface. This not only affects the quality of the operation but may also damage the internal conductor of the cable, leaving potential safety hazards.

[0003] To address the shortcomings of the existing technology, this invention provides a cable cutting device for cable wells, enabling integrated underground cable operations and solving the problems of inconvenient manual operation, low efficiency, and poor quality. Summary of the Invention

The positioning shaft 512 is connected to the positioning plate 511 through a bearing. The surface of the positioning shaft 512 is fixedly connected to the other end of the adjusting telescopic rod 404. That is, the end of the adjusting telescopic rod 404 away from the adjusting shaft 403 is fixed to the positioning shaft 512. By adjusting the extension and retraction of the telescopic rod 404, the positioning shaft 512 is driven to rotate, which in turn drives the entire clamping device 5 to rotate around the connecting rod 303, thereby realizing angle adjustment.

[0038] The working principle is as follows: First, the operators move the device to the cable well opening and use the lifting device 103 to adjust the installation position of the device so that the bracket 101 of the fixing device 1 fits against the edge of the cable well opening. Then, through the mounting holes on the fixing plate 102, bolts, expansion screws and other connectors are used to firmly fix the bracket 101 to the external fixing structure of the cable well to ensure the overall stability of the device and prevent shaking or tipping during operation. After fixing, the vertical plate 2 is rotated by the hinge 201 to rotate all working parts connected to the vertical plate 2, such as the lifting device 3, adjusting device 4, clamping device 5, and cutting device 7, into the cable well. The rotation angle of the vertical plate 2 is adjusted so that the working parts are aligned with the approximate position of the cable 10 to be processed, completing the installation, fixing and initial alignment of the device.

[0039] The lifting telescopic rod 301 of the lifting device 3 is activated by an external controller, controlling its extension and retraction. This causes the telescopic sleeve 302, connecting rod 303, and clamping device 5 connected to the connecting rod 303 to move up and down synchronously. Simultaneously, the lifting telescopic rod 301 drives the adjusting device 4, support frame 6, and cutting device 7, stripping device 8, and cleaning device 9 connected to the support frame 6 to move up and down synchronously. Based on the actual height of the cable 10 in the cable well, the extension and retraction of the lifting telescopic rod 301 is precisely adjusted so that the clamping ring 510 of the clamping device 5 is aligned with the position of the cable 10, and the belt cutting blade 710 of the cutting device 7, the stripping blade disc 806 of the stripping device 8, and the cleaning belt 903 and cleaning roller 909 of the cleaning device 9 are all aligned with the corresponding positions of the cable 10, completing the lifting and positioning process and ensuring that subsequent operations can be carried out accurately.

[0040] After positioning is completed, the clamping motor 503 and the moving motor 508 of the clamping device 5 are started. First, the moving motor 508 is controlled to run, driving the threaded screw 507 to rotate. Since the threads on the surface of the threaded screw 507 are symmetrically and oppositely arranged, the two moving slide plates 509 move in opposite directions along the moving slide rail 506, causing the four clamping rings 510 to open. The opening range is greater than the diameter of the cable 10, ensuring that the cable 10 can smoothly enter the clamping space. Then, the lifting device 3 and the adjusting device 4 are finely adjusted so that the cable 10 is located at the center of the clamping space formed by the combination of the four clamping rings 510. Next, the moving motor 508 is controlled to run in the opposite direction, driving the threaded screw 507 to rotate in the opposite direction, and the two moving slide plates 509 move relative to each other along the moving slide rail 506. The four clamping rings 510 are moved toward the cable 10 until the inner wall of the clamping rings 510 is tightly attached to the surface of the cable 10. The anti-slip texture on the inner wall of the clamping rings 510 increases the friction between them and the cable 10, thus initially achieving the clamping and fixing of the cable 10. Finally, the clamping motor 503 is controlled to operate, driving the clamping threaded rod 504 to rotate. Since the threads on the surface of the clamping threaded rod 504 are symmetrically and oppositely arranged, the two clamping slide plates 505 move relative to each other along the clamping slide rail 502, further adjusting the position of the clamping rings 510, so that the cable 10 is firmly clamped in the clamping space, ensuring that the cable 10 does not move or shift during subsequent cutting and stripping processes. The clamping force can be precisely adjusted by the controller to avoid excessive clamping and damage to the cable sheath.

[0041] After the cable 10 is clamped and fixed, the controller starts the adjustment device 4, which controls the extension and retraction of the adjustment telescopic rod 404. The adjustment telescopic rod 404 drives the positioning shaft 512 to rotate around the positioning plate 511, which in turn drives the clamping plate 501 to rotate around the connecting rod 303. Since the connecting rod 303 can rotate within the telescopic sleeve 302, the overall angle of the clamping device 5 can be adjusted. At the same time, the adjustment shaft 403 can be controlled to rotate, and the extension and retraction direction of the adjustment telescopic rod 404 can be adjusted to further optimize the tilt angle of the clamping device 5. Finally, the cable 10 is adjusted to a tilted upward state, so that the cutting position, stripping position, and cleaning position of the cable 10 are precisely aligned with the cutting device 7, the stripping device 8, and the cleaning device 9, respectively. This ensures that the belt cutting blade 710 can smoothly cut into the cable 10 during cutting, the stripping blade disc 806 can accurately contact the cable sheath during stripping, and the cleaning belt 903 and the cleaning roller 909 can fully cover the cable surface during cleaning. After the angle adjustment is completed, the adjustment device 4 is turned off to keep the angle of the clamping device 5 fixed.

[0042] After the angle adjustment is completed, the cutting device 7, peeling device 8, and cleaning device 9 are started by the controller to achieve synchronous operation of the three. The specific process is as follows: The cutting motor 704 is started, and the cutting motor 704 drives the cutting transmission wheel 707 to rotate around its own axis through gear transmission. The cutting transmission wheel 707 drives the belt cutting blade 710 to move synchronously. With the support of the first driven wheel 708 and the second driven wheel 709, the belt cutting blade 710 forms a stable cutting trajectory. At the same time, the controller controls the cutting telescopic rod 702 to slowly extend and retract downwards, which drives the intermediate plate 703, V-shaped frame 705 and the entire cutting device 7 to slowly move downwards, so that the moving belt cutting blade 710 contacts the cutting position surface of the cable 10 and slowly cuts into the cable 10. The cutting speed can be precisely adjusted by controlling the speed of the cutting motor 704 and the extension and retraction speed of the cutting telescopic rod 702 to ensure smooth cutting and avoid damage to the internal conductor of the cable 10, until the belt cutting blade 710 completely cuts the cable 10, completing the cutting operation.

[0043] While the cutting motor 704 is running, the cutting transmission wheel 707 drives the first stripping wheel 807 on one side to rotate synchronously. The first stripping wheel 807 drives the second stripping wheel 808, the third stripping wheel 809, and the fourth stripping wheel 810 to rotate synchronously via the stripping transmission belt 812. The fourth stripping wheel 810 drives the stripping rod 805 to rotate around its own axis. The stripping rod 805 drives several stripping blades 806 on the surface to rotate synchronously. At the same time, when the cutting telescopic rod 702 moves downward, it drives the stripping device 8 to move downward synchronously, so that the rotating stripping blades 806 come into contact with the outer sheath of the cable 10. Based on the diameter of the cable 10, the elastic telescopic rod 802 automatically extends and retracts, adjusting the position of the stripping blade 806 so that the blades of the stripping blade 806 accurately cut into the cable sheath without damaging the internal conductor. Several rotating stripping blades 806 cut the cable sheath into several uniform annular cuts, facilitating subsequent sheath stripping. During this process, the positioning wheel 811 restricts and tensions the stripping drive belt 812 to prevent it from slipping or deviating, ensuring a stable rotation speed of the stripping blade 806 and uniform stripping cuts. The stripping operation and the cutting operation are completed simultaneously, without the need for separate operation.

[0044] While the cutting device 7 is operating, the second driven wheel 709 drives the transmission rod 711 on the shaft to rotate synchronously. The transmission rod 711 drives the cleaning wheel 902, which is fixedly connected at one end, to rotate around its own axis. The cleaning wheel 902 drives the cleaning belt 903 on the surface to move synchronously. At the same time, when the cutting telescopic rod 702 moves downward, it drives the cleaning device 9 to move downward synchronously, so that the moving cleaning belt 903 contacts the unstripped rear end of the cable 10. The brush on the surface of the cleaning belt 903 performs preliminary cleaning of dust, oil, oxide layer and other impurities on the cable surface. At the same time, according to the diameter of the cable 10, the cleaning telescopic rod 905 automatically extends and retracts, adjusting the position of the cleaning roller 909 so that the cleaning roller 909 is in close contact with the surface of the cable 10. The cleaning roller 909 rotates synchronously with the cleaning belt 903 to perform secondary fine cleaning of the cable surface, removing residual small impurities, ensuring the cable surface is clean and reducing contamination during subsequent cable splicing. The cleaning operation is carried out simultaneously with the cutting and stripping operations, realizing integrated cable processing and greatly improving work efficiency.

[0045] It should be noted that the simultaneous operation of cutting, peeling, and cleaning is uniformly controlled by an external controller. The coordination of the actions of each component can be precisely adjusted by the controller to ensure the quality and efficiency of the operation.

[0046] After the cable 10 is cut, stripped, and cleaned, first turn off the cutting motor 704, clamping motor 503, and moving motor 508 to stop the operation of all components. Then, control the moving motor 508 to rotate in reverse, causing the clamping ring 510 to open and release the clamp on the cable 10. Next, control the lifting telescopic rod 301 to retract, causing each working component to move upward and out of the cable well space. Then, rotate the vertical plate 2 in reverse through the hinge 201 to rotate all working components to the outside of the cable well. Finally, loosen the connecting parts of the fixing device 1, disassemble and store the entire device, or hoist it to the next working position through the pull ring 103 to complete this operation.
