Description

Technical Field

[0001] The present application relates to the technical field of cable armor stripping, and in particular to a cable armor stripping tool for a cable. Background Art

[0002] Cables are used to transport electricity and are generally composed of multiple conductors, an insulation layer, an armor layer, and a sheath. The armor layer is a metal shielding layer used to prevent the influence of external electromagnetic interference signals on electricity. Usually, thin steel wire ropes or galvanized metal strips are used as armor layers wrapped around the conductors wrapped with an insulation layer.

[0003] When damage occurs inside the cable, the wire inside the cable needs to be repaired, so the armor layer needs to be stripped off before the repair. For example, an axial stripping device for the outer protective layer of an armored cable with a publication number of CN220553771U belongs to the field of equipment for stripping the outer protective layer of an armored cable, and includes a workbench, a lower stripping mechanism is fixed on the surface of the workbench, and an upper stripping mechanism is arranged above the lower stripping mechanism with an adjustable spacing. The armored cable passes between the upper stripping mechanism and the lower stripping mechanism that are symmetrically arranged above and below. The upper stripping mechanism and the lower stripping mechanism both include a conveying mechanism for clamping and conveying the armored cable, and a stripping knife is also arranged in the middle of the conveying mechanism in the upper stripping mechanism and the lower stripping mechanism, which is floating and rotatable. In this prior art, by setting the upper stripping mechanism and the lower stripping mechanism with adjustable spacing, accurate axial stripping of the armored cable is achieved, and at the same time, the armored cable can be stripped bidirectionally, thereby improving the stripping efficiency.

[0004] However, the above-mentioned prior art still has some defects when stripping the cable armor layer: due to the good flexibility of the cable itself, the cable is prone to shaking during the internal transportation process of the above-mentioned prior art. When the stripping knife provided by the above-mentioned prior art is used to strip the cable armor layer, the stripping knife may accidentally damage the wire insulation layer inside the armor layer when the shaking cable contacts the stripping knife, thereby greatly reducing the insulation performance of the wire, increasing the possibility of cable leakage and reducing safety, affecting the subsequent use of the cable.

[0005] Based on this, and in accordance with the above-mentioned viewpoints, there is still room for improvement in the existing technology for stripping cable armor layers. Summary of the invention

[0015] Preferably, a cylindrical protrusion is installed at one end of the driving shaft away from the connecting frame, and traction ropes matching the cylindrical protrusion are installed at both ends of the reciprocating rod. The end of the traction rope away from the reciprocating rod is set as an annular structure, and the annular structure is sleeved on the cylindrical protrusion.

DETAILED DESCRIPTION

[0035] The following is combined with Figures 1 to 9 This application is described in further detail.

[0036] An embodiment of the present application discloses a cable armor stripping tool for a cable, which avoids damaging the cable insulation layer and the like while stripping the armor layer.

[0037] Embodiment 1:

[0038] See also Figure 1 A cable armor stripping tool for cables includes a base 1, on which are mounted vertical frames 2 symmetrically arranged along the width direction thereof, and on each end of the vertical frames 2 away from the base 1 are mounted an annular frame 3, on which two annular frames 3 are mounted a stripping mechanism 4.

[0039] See also Figure 3 and Figure 4The stripping mechanism 4 includes: two sliding blocks 41, which are respectively slidably arranged inside the annular frame 3.

[0040] There are two connecting parts 42 , which are respectively arranged on the sliding block 41 .

[0041] The winding shaft 43 is disposed between the two connecting parts 42 , and two ends of the winding shaft 43 are respectively mounted on the corresponding connecting parts 42 .

[0042] During specific operation, the cable is passed through the middle of the annular frame 3, and the armor layer on one end of the cable is stripped off, and then the armor layer is wound on the winding shaft 43, and the end of the cable stripped of the armor layer is wound on an existing rotating roller (not shown in the figure), and the cable is driven to be wound by the existing rotating roller. At this time, the cable moves along the axial direction of the annular frame 3. When the cable moves along the axial direction of the annular frame 3, the sliding block 41 is driven to slide along the inner wall of the annular frame 3 through an external driving slider (not shown in the figure). During the sliding process of the sliding block 41, the winding shaft 43 is driven to rotate circumferentially along the inner wall of the annular frame 3 through the connecting part 42. The winding shaft 43 rotates synchronously during the circumferential rotation, and the armor layer can be wound during the rotation of the winding shaft 43.

[0043] Furthermore, the armor layer is synchronously wound and collected while the cable moves along the axial direction of the annular frame 3. Compared with the traditional cutting method with a knife, the above-mentioned method of collecting the armor layer can reduce the possibility of scratching the internal insulation layer of the cable, protect the internal conductors of the cable to the greatest extent possible, and ensure that the insulation layer is not damaged again.

[0044] See also Figure 4 As the armor layer wound on the winding shaft 43 gradually becomes thicker, in order to avoid the collapse of the armor layer wound on the winding shaft, the present invention also provides a connecting part 42 that can replace the winding shaft 43 at any time. Specifically, the connecting part 42 includes: a driving shaft 421, which is rotatably installed on the sliding block 41.

[0045] The connecting frame 422 is installed on the opposite surfaces of the two driving shafts 421.

[0046] The clamping block 423 is clamped on the connecting frame 422, and the connecting frame 422 is provided with fastening bolts for fixing the clamping block 423. The winding shaft 43 is arranged between the two clamping blocks 423, and the two ends of the winding shaft 43 are respectively installed on the clamping blocks 423 on the corresponding sides.

[0047] There are multiple winding shafts 43, and multiple clamping blocks 423 that cooperate with the winding shaft 43 are also provided. During the armor layer collection process, the external driving force (motor, etc.) drives the driving shaft 421 to rotate, and the driving shaft 421 rotates through the connecting frame 422 and the clamping block 423 to drive the winding shaft 43 to rotate. During specific work, when it is necessary to replace the winding shaft 43 wrapped with armor layers, the external driving slider is closed to stop the sliding of the sliding block 41. At this time, the sliding block 41 moves to the annular frame 3 bottom, remove the fastening bolts, and remove the clamping block 423 from the connecting frame 422. At this time, the wound armor layer is removed by the clamping block 423 and the winding shaft 43 cooperates with each other, and the new winding shaft 43 is clamped on the connecting frame 422 through the clamping block 423, and then the clamping block 423 is fixed to the connecting frame 422 by the fastening bolts. At this time, the armor layer on the cable is wound on the replaced winding shaft 43, and the above steps are repeated to continue to strip and collect the armor layer of the cable.

[0048] After the winding shaft 43 with the armor layer wrapped around it is removed, the armor layer wrapped around its surface is removed, and finally the winding shaft 43 with the armor layer removed is placed for standby use.

[0049] See also Figure 7 In order to reduce the use of external drive, the present invention also provides a gear 32 that meshes with the annular rack plate 31 to drive the drive shaft 421 to rotate. Specifically, the annular rack plates 31 are installed on the back sides of the annular frame 3, and the drive shaft 421 is installed with a gear 32 that meshes with the annular rack plate 31 on the same side.

[0050] During specific operation, the sliding block 41 slides along the inner wall of the annular frame 3 and synchronously drives the driving shaft 421 to rotate circumferentially. During the circumferential rotation of the driving shaft 421, the gear 32 and the annular rack plate 31 cooperate with each other to rotate. Then, during the rotation of the driving shaft 421, the connecting frame 422 and the clamping block 423 cooperate with each other to drive the winding shaft 43 to rotate. Then, without external drive, the driving shaft 421 can be driven to rotate by the linkage between the gear 32 and the annular rack plate 31.

[0051] See also Figure 5 , Figure 6 and Figure 7Since the armor layers of the cable are bonded to each other during long-term use, and rust and bond occur between the armor layers and the insulating layers, the armor layers are difficult to be stripped from the cable. In order to speed up the stripping of the armor layers and avoid the possibility of the winding shaft 43 being stuck when winding the armor layers due to rust and bond of the armor layers, the reciprocating rod 412 provided by the present invention can give external force to the armor layers, so that the armor layers can be pre-stripped before winding. Specifically, vertical rods 411 are provided on the sliding blocks 41, and reciprocating rods 412 are slidably sleeved on the two vertical rods 411. An annular protrusion 413 is provided on the vertical rods 411. A return spring 414 is sleeved on the vertical rods 411 and is located between the annular protrusion 413 and the reciprocating rod 412. One end of the return spring 414 is installed on the annular protrusion 413 on the corresponding side, and the other end of the return spring 414 is installed on the reciprocating rod 412.

[0052] When the armor layer is wound on the winding shaft 43, the armor layer is passed through the bottom of the reciprocating rod 412. During operation, when the armor layer is wound on the winding shaft 43, the reciprocating rod 412 is pressed downward by external force. At this time, the reciprocating rod 412 moves downward, and the reset spring 414 is gradually compressed. When the reset spring 414 is compressed to its maximum deformation, the external force is removed. At this time, the reset spring 414 is reset to drive the reciprocating rod 412 to reset. After the reciprocating rod 412 is reset, an external force is applied to the reciprocating rod 412 again. By repeating the above steps, the reciprocating rod 412 can be driven to move back and forth up and down. During the reciprocating movement of the reciprocating rod 412 up and down, the armor layer can be pre-stripped to avoid the problem of the winding shaft 43 being stuck due to the adhesion of the armor layer when the armor layer is rolled up, thereby improving the winding effect of the winding shaft 43.

[0053] Continue reading Figure 5 , Figure 6 and Figure 7 In order to reduce the use of external force, the present invention provides a traction rope 425 that cooperates with the drive shaft 421 to solve the above problem. Specifically, a cylindrical protrusion 424 is installed at one end of the drive shaft 421 away from the connecting frame 422, and traction ropes 425 that cooperate with the cylindrical protrusion 424 are installed at both ends of the reciprocating rod 412. The end of the traction rope 425 away from the reciprocating rod 412 is set as an annular structure, and the annular structure is sleeved on the cylindrical protrusion 424.

[0054] The cylindrical protrusion 424 forms a closed circle during its circumferential rotation. During specific operation, the driving shaft 421 rotates and synchronously drives the cylindrical protrusion 424 to rotate circumferentially. The cylindrical protrusion 424 moves through the traction rope 425 during its circumferential rotation. When the cylindrical protrusion 424 rotates circumferentially from the highest point to the lowest point of the closed circle, the cylindrical protrusion 424 drives the traction rope 425 to move downward. When the cylindrical protrusion 424 rotates circumferentially from the lowest point to the highest point of the closed circle, the traction rope 425 is no longer subjected to the pulling force of the cylindrical protrusion 424. At this time, the reset spring 414 drives the reciprocating rod 412 to reset, and the traction rope 425 moves upward synchronously. Therefore, during the circumferential rotation, the cylindrical protrusion 424 can drive the reciprocating rod 412 to move back and forth through the cooperation between the traction rope 425 and the reset spring 414.

[0055] The annular structure provided on the traction rope 425 and the sliding cooperation with the cylindrical protrusion 424 can ensure that the cylindrical protrusion 424 will not be wound around the traction rope 425 during the circumferential rotation.

[0056] See also Figure 5 , Figure 6 and Figure 7 In order to prevent the reciprocating rod 412 from causing excessive pressure on the armor layer during the pre-stripping process, which may cause the armor layer to break, the present invention also provides an elastic telescopic rod 417 and a transition roller 419 that cooperate with each other to reserve a sufficiently long length for the armor layer. Specifically, a support frame 415 corresponding to the sliding block 41 and having an inverted L-shaped structure is arranged between the annular frames 3, the short half of the support frame 415 is installed on the sliding block 41, and a transverse frame 416 is installed on the top of the long half of the support frame 415. The transverse frame 416 is installed with elastic telescopic rods 417 symmetrically distributed along its length direction, and fixed blocks 418 are installed on the telescopic ends of the elastic telescopic rods 417, and transition rollers 419 are installed between the fixed blocks 418 through bearings.

[0057] During the process of stripping the armor layer, the transition roller 419 can make the armor layer extend horizontally for a certain distance, providing a fulcrum for the reciprocating rod 412 to move up and down. During specific operation, when the reciprocating rod 412 moves downward to pre-strip the armor layer, if the armor layer is severely bonded, the force applied by the reciprocating rod 412 to press the armor layer downward may not be enough to pre-strip the armor layer at one time, that is, the reciprocating rod 412 cannot continue to move downward at the moment of abutting against the armor layer. At this time, the armor layer distributes the excess downward pressure of the reciprocating rod 412 to the transition roller 419, and the transition roller 419 cooperates with the elastic telescopic rod 417 through the fixed block 418 to move toward one side of the support frame 415 to balance the excess downward pressure of the reciprocating rod 412. During the movement of the transition roller 419, the plane where the armor layer contacts the reciprocating rod 412 moves downward, and then the reciprocating rod 412 can continue to move downward along the plane of the armor layer for a certain distance.

[0058] When the reciprocating rod 412 reaches the lowest position and is reset by the reset spring 414, the transition roller 419 is reset synchronously. The above steps can be repeated to perform multiple pre-stripping treatments on the armor layer at that location. Multiple pre-stripping steps can be coordinated with each other to strip the armor layer that is severely bonded.

[0059] In this process, the distance between the transition roller 419 and the reciprocating rod 412 is large enough, that is, the armor layer needs to be reserved for a sufficiently long length, that is, the reciprocating rod 412 and the transition roller 419 will not collide. At the same time, it can compensate for the length of the armor layer that the winding shaft 43 still needs to wind when a single pre-stripping is unsuccessful (that is, multiple pre-strippings are required to strip the armor layer that is severely adhered).

[0060] See also Figure 8 In order to avoid the possibility that the wound armor layer is too thick and may collapse during the winding process or even collide with the internal parts of the tool, the limit frame 33 provided by the present invention can limit the wound armor layer, and a corresponding limit frame 33 is arranged between the annular frames 3, which is used to limit the wound cable armor layer and has an annular structure.

[0061] During specific operation, the limiting frame 33 can limit the armor layer after stripping and winding during the armor layer stripping process to avoid the possibility of collapse of the wound armor layer or even collision of parts inside the tool.

[0062] See also Figure 7 and Figure 8 Since the armor layer is wound on the cable at an angle, the armor layer may be offset to a certain extent when it is stripped off and wound. Although the armor layer will not collapse due to the limiting frame 33 during the winding process, the armor layer may collapse when the armor layer is removed. Therefore, in order to avoid the above situation, the movable frame 34 provided by the present invention cooperates with the limiting frame 33 to align and level the armor layer during the winding process. Specifically, a plurality of evenly distributed movable frames 34 are arranged on the circumferential surface of the annular frame 3 for sliding along its circumferential direction. The movable frames 34 corresponding to the same annular frame 3 are connected to the limiting frame 33. A rectangular protrusion is installed on the annular frame 3, and a telescopic spring rod 35 is installed on the rectangular protrusion. The end of the telescopic spring rod 35 away from the rectangular protrusion is installed on the corresponding limiting frame 33 for resetting the limiting frame 33.

[0063] The sliding blocks 41 are all equipped with linkage frames 36 , and one end of the linkage frames 36 away from the corresponding sliding blocks 41 is equipped with linkage blocks 37 , and the linkage blocks 37 are provided with guiding inclined surfaces matched with the moving frames 34 .

[0064] During specific operation, when the armor layer is wound on the winding shaft 43, the sliding block 41 synchronously drives the linkage block 37 to rotate circumferentially through the linkage frame 36. When the linkage block 37 moves to the moving frame 34, the guiding inclined surface on the linkage block 37 contacts the moving frame 34 and drives the moving frame 34 to move toward one side of the wound armor layer. During the movement of the moving frame 34, the limiting frame 33 is driven to align and level the armor layer. When the linkage block 37 passes over the corresponding moving frame 34, the telescopic spring rod 35 and the rectangular protrusion cooperate with each other to reset the limiting frame 33, so that the limiting frame 33 returns to the starting position, and then during the movement of the limiting frame 33, the side of the wound armor layer can be flattened, reducing the risk of collapse of the wound armor layer. Multiple moving frames 34 cooperate with the linkage blocks 37 to perform multiple alignment and leveling processes on the wound armor layer when the sliding block 41 slides circumferentially around the annular frame 3.

[0065] Replay Figure 2 As the thickness of the armor layer increases, when the armor layer reaches a certain thickness, it needs to be removed. The movable rod 21 provided by the present invention can cooperate with the external force to pull the limit frame 33 to make way for the clamping block 423. Specifically, the vertical frame 2 is slidably provided with movable rods 21 corresponding to the annular frame 3 one by one, and the end of the movable rod 21 close to the limit frame 33 is connected to the corresponding limit frame 33.

[0066] During specific operation, when the armor layer is wound to a certain thickness, the moving rod 21 is pulled by external force to make the two moving rods 21 move away from each other. During the movement of the moving rod 21, the limiting frames 33 are driven to move away from each other, so that the spacing between the limiting frames 33 is greater than the distance between the two clamping blocks 423, thereby ensuring that the clamping blocks 423 and the winding shaft 43 will not collide with the limiting frames 33 when they are taken out.

[0067] When the limiting frame 33 moves away, the clamping block 423 , the winding shaft 43 and the wound armor layer are removed from the annular frame 3 .

[0068] In addition, the moving rod 21 can also cooperate with the vertical frame 2 to stabilize the limiting frame 33, thereby avoiding the instability of the limiting frame 33 being connected to the annular frame 3 only through the moving frame 34.

[0069] Embodiment 2:

[0070] Reference Fig. 9 On the basis of the first embodiment, the rotating rod 5 provided by the present invention can also perform winding processing on the armor layer. Specifically, two movable sliders 51 are slidably provided on the base 1 along its length direction, and a rectangular connecting block 52 is clamped on the movable slider 51. A rotating rod 5 is provided between the two vertical frames 2, and both ends of the rotating rod 5 are respectively installed on the rectangular connecting block 52 through bearings.

[0071] During specific operation, the cable is placed directly above the rotating rod 5, and the armor layer is wound around the rotating rod 5, so that the armor layer winding point is located on the side of the vertical frame 2, and the winding point gradually moves away from the vertical frame 2 as the rotating rod 5 moves along the length direction of the base 1, and the cable is moved along the width direction of the base 1, and the cable rotates synchronously during the movement, and the rotating rod 5 is driven to rotate by an external drive motor (not shown in the figure). During the rotation of the rotating rod 5, the armor layer on the cable during the movement can be wound, and at this time, the cable rotates synchronously to release the armor layer. When the armor layer is wound on the rotating rod 5 to a certain thickness, the movable slider 51 is pushed by an external driving force. During the movement of the movable slider 51, the rectangular connecting block 52 drives the rotating rod 5 in the rotating process to move synchronously, so that the rotating rod 5 moves in the direction away from the vertical frame 2 along the winding point. When the armor layer on the rotating rod 5 is fully wound, the rectangular connecting block 52 is removed from the movable slider 51. At this time, the rotating rod 5 that is fully wound with the armor layer is also removed, and then a new rotating rod 5 is replaced. Then the above actions are repeated to strip the armor layer.

[0072] The implementation principle of the present invention is:

[0073] (1): Pass the cable through the middle of the annular frame 3, and peel off the armor layer on one end of the cable, then wind the armor layer on the winding shaft 43, and wind the end of the cable stripped of the armor layer on the existing rotating roller, and drive the cable to be wound by the existing rotating roller. At this time, the cable moves along the axial direction of the annular frame 3. When the cable moves along the axial direction of the annular frame 3, the sliding block 41 is driven by the external driving slider to slide along the inner wall of the annular frame 3. During the sliding process of the sliding block 41, the winding shaft 43 is driven by the connecting part 42 to rotate circumferentially along the inner wall of the annular frame 3. During the circumferential rotation of the winding shaft 43, the winding shaft 43 rotates synchronously, and the armor layer can be wound during the rotation of the winding shaft 43.

[0074] (2): When the armor layer is wound on the winding shaft 43, the reciprocating rod 412 is pressed downward by an external force. At this time, the reciprocating rod 412 moves downward, and the return spring 414 is gradually compressed. When the return spring 414 is compressed to its maximum deformation, the external force is removed. At this time, the return spring 414 is reset and drives the reciprocating rod 412 to reset. After the reciprocating rod 412 is reset, an external force is applied to the reciprocating rod 412 again. Repeating the above steps can drive the reciprocating rod 412 to move back and forth up and down. During the reciprocating movement of the reciprocating rod 412 up and down, the armor layer can be pre-stripped.

[0075] (3): During the winding process of the armor layer on the winding shaft 43, the sliding block 41 synchronously drives the linkage block 37 to rotate circumferentially through the linkage frame 36. When the linkage block 37 moves to the moving frame 34, the guiding inclined surface on the linkage block 37 contacts the moving frame 34 and drives the moving frame 34 to move toward the side of the wound armor layer. During the movement of the moving frame 34, the limit frame 33 is driven to align and level the armor layer. After the linkage block 37 passes over the corresponding moving frame 34, the telescopic spring rod 35 cooperates with the rectangular protrusion to reset the limit frame 33, so that the limit frame 33 returns to the starting position, and then the side of the wound armor layer can be flattened during the movement of the limit frame 33.

[0076] (4): Finally, remove the clamping block 423, the winding shaft 43 and the wound armor layer from the annular frame 3.

[0077] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
