Description

Technical Field

[0001] This invention relates to the field of cable stripping device technology, specifically to a portable integrated stripping device for the outer sheath and steel armor of control cables. Background Technology

[0002] A cable stripping device is a specialized piece of equipment for automatically and semi-automatically stripping the outer insulation layer of cables. Through mechanical structures and electric actuators, it quickly and accurately strips the plastic outer insulation layer of cables and is suitable for scenarios in production maintenance and equipment installation.

[0003] Currently, in power construction and maintenance work, stripping the outer sheath and inner steel armor of control cables typically requires the sequential use of multiple tools such as utility knives, wire strippers, and hydraulic shears. Operators need to frequently switch between tools, which is not only inefficient and inconvenient to carry, but also poses a risk of damaging the cable core or causing workplace injuries due to improper operation. Therefore, there is an urgent need for a portable tool that integrates multiple functions and is simple and safe to operate. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a portable integrated stripping device for the outer sheath and steel armor of control cables. The device can simultaneously complete cable clamping, positioning, outer sheath stripping, and steel armor stripping by a single handle, making it simple and convenient to operate and effectively improving work efficiency.

[0005] This invention is achieved through the following technical solution: A portable integrated stripping device for the outer sheath and steel armor of control cables is provided, comprising: The linkage component includes a housing and a transmission mechanism disposed within the housing. The transmission mechanism is configured to be driven by a single operating handle and can synchronously output a first rotational motion and a second rotational motion. The clamping and positioning assembly includes an arc-shaped clamping plate assembly for axially clamping the cable and a pair of rollers for radially positioning the cable. The arc-shaped clamping plate assembly is driven by a first rotational motion to clamp or release the cable, and the pair of rollers is driven by a second rotational motion to move toward or away from each other. The stripping assembly includes at least one first stripping blade with adjustable stripping depth, and the stripping assembly is disposed on the side of the arc-shaped clamping plate assembly and is movable therewith.

[0006] Furthermore, the transmission mechanism includes: A second rotating shaft is rotatably disposed within the housing, and the operating handle is a first anti-slip handle fixedly connected to one end of the second rotating shaft; A second gear fixedly mounted on a second rotating shaft; The first gear that meshes with the second gear; A worm gear fixedly connected coaxially to the first gear; And a worm wheel that meshes with the worm, the worm wheel being fixedly sleeved on the first rotating shaft, the first rotating shaft being rotatably mounted on the housing; The first rotational motion is output from the output end of the first rotating shaft, and the second rotational motion is output through the second helical gear on the first rotating shaft driving the first helical gear meshing with it.

[0007] Furthermore, the mechanism for outputting the second rotary motion includes: A first slide rail is fixedly installed on the outside of the housing. A bidirectional threaded rod is rotatably installed inside the first slide rail. A first helical gear is fixedly sleeved on the bidirectional threaded rod. Two first sliding shafts are respectively threaded onto two reverse threads of a bidirectional threaded rod and can slide within the groove of the first sliding rail; A pair of rollers are rotatably mounted at the ends of the two first sliding shafts.

[0008] Furthermore, the curved clamping plate assembly includes: The first clamping plate is fixed relative to the housing; A third rotating shaft is rotatably mounted on the housing, and the third rotating shaft is coaxially and fixedly connected to the output end of the first rotating shaft to receive the first rotational motion; In addition, a second clamping plate is fixedly connected to the third rotating shaft. The second clamping plate can slide relative to the first clamping plate to form a clamping or releasing of the cable together with the first clamping plate.

[0009] Furthermore, the stripping components include: A first sliding box and a second sliding box are respectively fixedly connected to the first clamping plate and the second clamping plate; Two second slide rails are slidably installed in the first and second sliding boxes; The second springs are respectively set in the two second slide rails, with one end of the second spring abutting the end of the second slide rail and the other end connected to a first slider that can slide along the second slide rail; There are two first stripping blades, which are fixedly mounted on two first sliders respectively. The second spring provides elastic pressure to the first stripping blades toward the cable.

[0010] Furthermore, the stripping assembly also includes a depth adjustment mechanism, which includes: Depth limiting screws are fixedly connected to the ends of each of the second slide rails; The depth limiting screw is threadedly connected to the corresponding first or second sliding box. By turning the depth limiting screw, the second slide rail and the first stripping blade on it can be moved relative to the sliding box to adjust the stripping depth.

[0011] Furthermore, it also includes a steel armor stripping assembly, which comprises: The motor has a second stripping blade for cutting steel armor fixedly mounted on its output shaft; The mounting bracket is used to support the motor and is rotatably connected to the end of a depth limiting screw, so that the steel armor stripping assembly can move synchronously with the depth adjustment mechanism. An angle adjustment mechanism is configured to allow the motor and the second stripping blade to switch between a cutting position parallel to the cable axis and a rotating stripping position perpendicular to the cable axis.

[0012] Furthermore, the mounting bracket includes: A first fixing plate that is rotatably connected to the end of the depth limiting screw; The motor is fixedly mounted on the second fixed plate, which is rotatably connected to the first fixed plate via a rotating plate. The angle adjustment mechanism includes a second slide shaft that is slidably inserted in the first fixed plate, and an elastic positioning component for locking the second slide shaft in different positions.

[0013] Furthermore, the flexible positioning component includes: A fixed disc, which is rotatably mounted on the second sliding shaft; A fixed cylinder is fixedly mounted on the first fixed plate; The third spring is located between the fixed disc and the fixed cylinder; The second sliding shaft is provided with a first limiting block and multiple second limiting blocks. When the second sliding shaft is pressed to the first position by the third spring, the second limiting block engages with the first fixed plate to prevent rotation. When the second sliding shaft is pulled outward to the second position, the first limiting block can engage with the rotating plate. At this time, rotating the second sliding shaft can drive the motor and the second stripping blade to rotate as a whole to adjust the angle.

[0014] An axial reset mechanism consisting of a first spring and a turntable is provided between the second rotating shaft and the housing. This mechanism is used to engage the second gear with the first gear when the first anti-slip handle is pressed, and to disengage the two gears when the handle is released.

[0015] The beneficial effects of this invention are: The core of this invention lies in using a set of linkage components to decompose a single input action into two collaborative outputs: control of clamping and positioning, and to integrate the stripping function module into the clamping structure.

[0016] I. High integration and one-click linkage: This invention creatively combines the axial clamping (via an arc-shaped clamping plate) and radial positioning (via rollers) functions of the cable with a set of linkage transmission mechanisms. Users only need to turn a non-slip handle to simultaneously drive the clamping plate to clamp the cable and the rollers to hold the cable, achieving "one-click" quick fixing, greatly simplifying the operation process and improving work efficiency.

[0017] II. Adaptive peeling and anti-jamming design: The stripping assembly employs a "spring-loaded slider" design, giving the stripping blade flexibility. When stripping the outer sheath, the blade can remain close to the cable surface; if it accidentally encounters hard objects such as the internal steel armor, the blade can automatically retract to avoid them, effectively preventing the tool from jamming or damaging the cable core, thus improving the safety and reliability of the operation.

[0018] III. Modular depth adjustment and steel armor processing capabilities: The cutting depth of the stripping blade and steel armor cutting blade can be precisely adjusted by rotating the depth limit screw to accommodate cables of different specifications. The integrated electric steel armor stripping module can achieve two working modes—axial cutting or circumferential rotation stripping—through a simple angle adjustment mechanism, offering comprehensive functions and wide adaptability.

[0019] IV. Portability and Applicability: The entire device has a compact structure, integrating complex functions into a handheld tool, making it easy to carry to various work sites. Its clamping and positioning mechanism can be adapted to cables of different diameters, making it highly versatile. Attached Figure Description

[0032] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0033] Please see Figure 1-11 The present invention provides the following technical solution: A portable control cable sheath and steel armor integrated stripping device, the linkage component 1 includes a housing 101 and a transmission mechanism disposed in the housing 101. The transmission mechanism is configured to be driven by a single operating handle and can synchronously output a first rotational motion and a second rotational motion.

[0034] The clamping and positioning assembly includes an arc-shaped clamping plate assembly 3 for axially clamping the cable and a pair of rollers 113 for radially positioning the cable. The arc-shaped clamping plate assembly 3 is driven by a first rotational motion to clamp or release the cable, and the pair of rollers 113 is driven by a second rotational motion to move toward or away from each other.

[0035] The stripping assembly 2 includes at least one first stripping blade 204 with adjustable stripping depth. The stripping assembly 2 is disposed on the side of the arc-shaped clamping plate assembly 3 and is movable therewith.

[0036] This device mainly consists of three parts: the linkage component 1 on the right is the power input and distribution center; the clamping component 3 in the middle is used to grip the cable; the stripping component 2 integrated on the clamping component 3 is responsible for stripping the outer sheath; and the optional steel armor stripping component 4 is used to handle the inner steel armor.

[0037] Working mechanism of linkage component 1: See Figure 5 , 6 7. The core of the linkage component 1 is to achieve "single input, dual output". The user first presses the first anti-slip handle 109 along the axial direction, compressing the first spring 108, which drives the second rotating shaft 106 and its second gear 107 to move inward, engaging with the first gear 105. Then, the first anti-slip handle 109 is rotated. The power transmission path is as follows: First anti-slip handle 109 → Second rotating shaft 106 → Second gear 107 → First gear 105 → Worm 104 → Worm wheel 103 → First rotating shaft 102.

[0038] When the first rotating shaft 102 rotates, two motions are output simultaneously: First output (driving clamping): The left end of the first rotating shaft 102 directly drives the third rotating shaft 302 to rotate, thereby driving the second clamping plate 303 to slide relative to the first clamping plate 301 to achieve clamping.

[0039] Second output (drive positioning): The second helical gear 115 on the first rotating shaft 102 rotates, driving the first helical gear 114 meshing with it to rotate, thereby driving the bidirectional threaded rod 111 to rotate. The two first sliding shafts 112 on the bidirectional threaded rod 111 move towards or away from each other, driving the roller 113 to clamp or release the cable, realizing radial auxiliary positioning.

[0040] Adjustment and operation of component 2: See Figure 3 , 4 The stripping depth is adjusted by rotating the depth limit screw 205. Tightening the screw moves the entire second slide rail 201 and the first stripping blade 204 on it, determining the distance between the blade tip and the cable surface. The second spring 202, through the first slider 203, constantly applies a downward elastic pressure to the first stripping blade 204, ensuring a stable cutting depth and overload retraction. The handle 208 allows the entire device to be pushed or pulled along the cable for linear stripping.

[0041] Angle adjustment of steel armor stripping component 4: See Figure 9 , 1011. When it is necessary to remove the steel armor, first adjust the second stripping blade 407 to the appropriate depth using the depth adjustment mechanism. To change the cutting method (e.g., from linear cutting to rotary cutting), the following operations can be performed: Pull the second anti-slip handle 411 outward to overcome the elastic force of the third spring 409, so that the second limiting block 413 on the second sliding shaft 402 is disengaged from the first fixing plate 401.

[0042] At this time, the first limiting block 412 engages with the rotating plate 403. Rotating the second anti-slip handle 411 will cause the rotating plate 403, the second fixed plate 404, and the entire motor 405 to rotate 90 degrees via the first limiting block 412.

[0043] Release the second anti-slip handle 411, and under the action of the third spring 409, the second limit block 413 re-engages with the first fixing plate 401, locking the angle. At this time, the motor 405 can be started to perform rotational peeling.

[0044] The control cable to be stripped is placed between the first clamping plate 301 and the second clamping plate 303 of the arc-shaped clamping plate assembly 3. The operator first presses the first anti-slip handle 109, moving it towards the fixed housing 101. The first anti-slip handle 109 drives the second rotating shaft 106 to slide against the inner wall of the fixed housing 101. The second rotating shaft 106 then drives the second gear 107 to move. As the second gear 107 moves, it drives the turntable 116 to move, thus compressing the first spring 108 until the second gear 107 contacts part of the inner wall of the fixed housing 101. Figure 7As can be seen, the inner wall of the fixed housing 101 is located on one side of the first gear 105, and its inner wall is higher than that of the fixed housing 101 fixedly connected to the first spring 108. At this time, the second gear 107 meshes with the outer surface of the first gear 105. When the first anti-slip handle 109 is rotated, the first anti-slip handle 109 will drive the second rotating shaft 106 to rotate. The outer surface of the second rotating shaft 106 will rotate on the inner wall of the fixed housing 101. At the same time, the second rotating shaft 106 will drive the second gear 107 to rotate. The second gear 107 will drive the meshing first gear 105 to rotate. When the first gear 105 rotates, it will drive the worm 104 to rotate. The outer surfaces of both ends of the worm 104 will rotate on the inner wall of the fixed housing 101. At the same time, the worm 104 will drive the meshing worm wheel 103 to rotate. When the worm wheel 103 rotates, it will drive the first rotating shaft 102 to rotate on the fixed housing 101. As the inner wall rotates, the first rotating shaft 102 will synchronously drive the third rotating shaft 302 and the second helical gear 115 to rotate. The second helical gear 115 will synchronously drive the meshing first helical gear 114 to rotate. The first helical gear 114 will drive the bidirectional threaded rod 111 fixed on the inner wall to rotate. The two ends of the bidirectional threaded rod 111 will rotate on the inner wall of the first slide rail 110. When the bidirectional threaded rod 111 rotates, it will drive the two first slide shafts 112 to move towards each other. The two first slide shafts 112 will drive the rollers 113 to move towards each other synchronously until the rollers 113 are tightly attached to the outer surface of the cable, realizing radial auxiliary positioning of the cable. At the same time, the first rotating shaft 102 drives the third rotating shaft 302 to rotate. The third rotating shaft 302 drives the second clamping plate 303 to slide relative to the first clamping plate 301. The two gradually clamp the outer cable, completing the axial fixation.

[0045] At this time, pulling the handle 208 will drive the first stripping blade 204 to strip the outer sheath of the cable, thus eliminating the need to operate multiple parts separately, reducing the number of operation steps, and solving the problem that existing cable stripping devices require frequent switching of different tools to complete the stripping operation, which wastes a lot of time in tool retrieval, replacement and debugging, resulting in a decrease in overall work efficiency.

[0046] When straight stripping of external cables is required, the depth limiting screw 205 located inside the first sliding box 206 is rotated. The outer surface of the depth limiting screw 205 moves spirally along the inner wall of the first sliding box 206, simultaneously causing the second slide rail 201 to slide along the inner wall of the first sliding box 206. The second slide rail 201 synchronously drives the second spring 202 and the first slider 203 to move. The first slider 203 drives the connected first stripping blade 204 to move. The extension depth of the first stripping blade 204 is adjusted according to the thickness of the cable sheath and steel armor. The second spring 202 moves through the first slider 202... 3. Apply continuous pressure to the first stripping blade 204 to ensure that the first stripping blade 204 is in close contact with the outer surface of the cable during the stripping process. At this time, the handle 208 can be pulled to move the portable integrated control cable sheath and steel armor stripping device in a straight line along the outer surface of the outer cable. At this time, the first stripping blade 204 will strip the cable sheath. When the first stripping blade 204 contacts the steel armor protective layer during the stripping process, the first stripping blade 204 will squeeze the second spring 202, so that the first stripping blade 204 will retract to avoid the obstacle. After passing the obstacle, it will immediately reset and continue to strip the cable sheath.

[0047] When it is necessary to rotate the first stripping blade 204 to facilitate the removal of the cable sheath, the depth limit screw 205 located inside the second sliding box 207 is rotated to adjust the extension depth of the first stripping blade 204 according to the thickness of the cable sheath and steel armor. Once adjusted to the appropriate position, the arc-shaped clamping plate assembly 3 rotates to drive the stripping assembly 2 to rotate, facilitating the removal of the cable sheath. Figures 2 to 4 In the diagram, it can be clearly seen that the first stripping blade 204 located inside the first sliding box 206 has an inclined angle for straight stripping, while the first stripping blade 204 located inside the second sliding box 207 is vertical for rotary stripping. When rotating the arc-shaped clamping plate assembly 3, if there is resistance during rotation due to the roller 113 clamping the external cable, the two first sliding shafts 112 can be driven to move in opposite directions by rotating the first anti-slip handle 109 in the opposite direction, thereby reducing the rotational resistance and rotating the corresponding depth limit. Screw 205 is used to adjust the depth of the first stripping blade 204 for rotating stripping. This device, by setting stripping component 2, allows the operator to pull handle 208 to drive the first stripping blade 204 when stripping external cables. When the first stripping blade 204 contacts the steel armor inside the cable, the head of the first stripping blade 204 will move slightly upward to compress the second spring 202, thus automatically disengaging from the jammed state. After disengaging from the jammed state, the first stripping blade 204 can automatically reset and move downward to continue the stripping operation, improving the smoothness of the operation.

[0048] The working process of this invention: The control cable to be stripped is placed between the first clamping plate 301 and the second clamping plate 303 of the arc-shaped clamping plate assembly 3. The operator first presses the first anti-slip handle 109, moving it towards the fixed housing 101. The first anti-slip handle 109 drives the second rotating shaft 106 to slide against the inner wall of the fixed housing 101. The second rotating shaft 106 then drives the second gear 107 to move. As the second gear 107 moves, it drives the turntable 116 to move, thus compressing the first spring 108 until the second gear 107 contacts part of the inner wall of the fixed housing 101. Figure 7As can be seen, the inner wall of the fixed housing 101 is located on one side of the first gear 105, and its inner wall is higher than that of the fixed housing 101 fixedly connected to the first spring 108. At this time, the second gear 107 meshes with the outer surface of the first gear 105. When the first anti-slip handle 109 is rotated, the first anti-slip handle 109 will drive the second rotating shaft 106 to rotate. The outer surface of the second rotating shaft 106 will rotate on the inner wall of the fixed housing 101. At the same time, the second rotating shaft 106 will drive the second gear 107 to rotate. The second gear 107 will drive the meshing first gear 105 to rotate. When the first gear 105 rotates, it will drive the worm 104 to rotate. The outer surfaces of both ends of the worm 104 will rotate on the inner wall of the fixed housing 101. At the same time, the worm 104 will drive the meshing worm wheel. When the worm gear 103 rotates, it drives the first rotating shaft 102 to rotate on the inner wall of the fixed housing 101. The first rotating shaft 102 simultaneously drives the third rotating shaft 302 and the second helical gear 115 to rotate. The second helical gear 115 simultaneously drives the meshing first helical gear 114 to rotate. The first helical gear 114 drives the double-threaded rod 111 fixed on the inner wall to rotate. The two ends of the double-threaded rod 111 rotate on the inner wall of the first slide rail 110. When the double-threaded rod 111 rotates, it drives the two first slide shafts 112 to move towards each other. The two first slide shafts 112 drive the rollers 113 to move towards each other synchronously until the rollers 113 are in close contact with the outer surface of the cable, realizing radial auxiliary positioning of the cable. At the same time, the first rotating shaft 10... 2. The third rotating shaft 302 rotates, driving the second clamping plate 303 to slide relative to the first clamping plate 301. The two gradually clamp the external cable, completing axial fixation. When straight stripping is required, the depth limiting screw 205 located inside the first sliding box 206 is rotated. The outer surface of the depth limiting screw 205 will spirally move on the inner wall of the first sliding box 206, simultaneously driving the second slide rail 201 to slide on the inner wall of the first sliding box 206. The second slide rail 201 will synchronously drive the second spring 202 and the first slider 203 to move. The first slider 203 will drive the connected first stripping blade 204 to move. The extension depth of the first stripping blade 204 is adjusted according to the thickness of the cable sheath and steel armor. The second spring 202... 2. Continuous pressure is applied to the first stripping blade 204 via the first slider 203 to ensure tight contact between the first stripping blade 204 and the outer cable surface during the stripping process. Simultaneously, when the depth limiting screw 205 is rotated, one of the depth limiting screws 205 will move the first fixing plate 401. The first fixing plate 401 will then cause the outer surfaces of the second sliders 415 on both sides to slide along the inner wall of the third slide rail 416. At the same time, the first fixing plate 401 will move the steel armor stripping assembly 4 as a whole until it reaches the appropriate position. Then, the handle 208 can be pulled to move the portable integrated control cable sheath and steel armor stripping device linearly along the outer surface of the outer cable. At this point, the first stripping blade 204 will strip the cable sheath.During the stripping process, when the first stripping blade 204 contacts the cable sheath, it compresses the second spring 202, causing it to retract and avoid the obstacle. After passing the obstacle, it immediately returns to its original position and continues stripping the cable sheath. Simultaneously, the motor 405 is activated, driving the output shaft 406 to rotate. The output shaft 406 then drives the second stripping blade 407 to rotate, at which point the second stripping blade 407 strips the steel armor inside the cable. While the depth limit screw 205 limits the depth of the first stripping blade 204, it also limits the depth of the second stripping blade 407. At the depth limit, the cable sheath and steel armor are moved linearly. When it is necessary to rotate the first stripping blade 204 to facilitate the stripping of the cable sheath, the depth limit screw 205 located inside the second sliding box 207 is rotated to adjust the extension depth of the first stripping blade 204 according to the thickness of the cable sheath and steel armor. At the same time, the operator moves the second anti-slip handle 411, which drives the second sliding shaft 402 to move. The outer surface of the second sliding shaft 402 slides along the inner wall of the fixed cylinder 410, the first fixed plate 401, and the rotating plate 403. When the fixed plate 408 slides along the inner wall of the fixed cylinder 410, it compresses the third spring 409. At this time, the outer surface of the second limiting block 413 is no longer in contact with the inner wall of the first fixed plate 401, and the outer surface of the first limiting block 412 is in contact with the inner wall of the rotating plate 403. When the second anti-slip handle 411 is rotated, the second anti-slip handle 411 will drive the first limiting block 412 to rotate, and the first limiting block 412 will drive the rotating plate 403 to rotate. The outer surface of the rotating plate 403 will rotate along the inner wall of the first fixed plate 401, while simultaneously driving the motor 405 and the second stripping blade 407 to rotate. After rotating the motor 405 and the second stripping blade 407 ninety degrees, the direction of the second stripping blade 407 is adjusted. At this time, the operator no longer pulls the second anti-slip handle 411. The elastic force of the third spring 409 will drive the fixed plate 408 to move, and the fixed plate 408 will drive the second sliding shaft 402 to move. The second sliding shaft 402 will drive the outer surface of the second limit block 413 to fit against the inner wall of the first fixed plate 401. After adjusting to the appropriate position, rotating the arc-shaped clamping plate assembly 3 will drive the stripping assembly 2 and the second stripping blade 407 to rotate, facilitating the stripping of the cable sheath and steel armor. Figures 2 to 4In the diagram, it can be clearly seen that the first stripping blade 204 located inside the first sliding box 206 has an inclined angle and is used for straight stripping, while the first stripping blade 204 located inside the second sliding box 207 is vertical and is used for rotational stripping. When rotating the arc-shaped clamping plate assembly 3, if there is resistance when the roller 113 clamps the external cable, the two first sliding shafts 112 can be driven to move in opposite directions by rotating the first anti-slip handle 109 in the opposite direction to reduce the rotational resistance. The depth of the first stripping blade 204 for rotational stripping can be adjusted by rotating the corresponding depth limit screw 205.

[0049] The wiring diagram of motor 405 in this invention is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of motor 405 will not be explained in detail.

[0050] In summary, when using this invention, the cable is placed between the clamping plate and the roller 113, and the first anti-slip handle 109 is pressed and rotated to simultaneously and securely fix the cable. After adjusting the stripping depth, pulling or rotating the device will sequentially remove the outer sheath and the steel armor.
