Description

Technical Field

[0001] The utility model relates to the field of wire twisting devices, in particular to a wire twisting device for cables with high stability. Background Art

[0002] Cables exposed to the elements for extended periods of time are prone to strand breakage and unraveling due to various factors, resulting in reduced mechanical and electrical properties. A common solution is to use a twisting device to wrap a protective layer of multiple repair strips around the cable to reinforce and protect it, resulting in a cable with a protective layer.

[0003] Existing twisting devices usually include a frame, a traveling mechanism and a twisting mechanism. The traveling mechanism and the twisting mechanism are arranged on the frame. The movement of the traveling mechanism on the cable drives the twisting device to move along the extension direction of the cable. During the movement of the traveling mechanism, the twisting mechanism can wrap the repair strip around the outside of the cable, thereby completing the reinforcement and protection of the cable.

[0004] However, because the frame is typically open, external factors such as wind and vibration can cause the twisting mechanism to wobble, affecting its overall stability. This not only increases operational difficulty but can also reduce work efficiency and safety. Furthermore, the open frame fails to protect the travel and twisting mechanisms mounted on it, making wind and vibration more susceptible to impacting the accuracy and uniformity of the patch strip winding.

DETAILED DESCRIPTION

[0039] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0040] The present technical solution provides a highly stable cable twisting device, comprising a protective cover 1, a running mechanism 2, a twisting mechanism 3, and a clamping mechanism 5; a wire-passing notch 11 is provided at the bottom of the protective cover 1 for allowing the cable 6 and the repair strip 7 to pass through; the running mechanism 2, the twisting mechanism 3, and the clamping mechanism 5 are all installed inside the protective cover 1, and the clamping mechanism 5 and the twisting mechanism 3 are arranged in sequence along the twisting direction;

[0041] The clamping mechanism 5 is used to clamp the fixed ends of the cable 6 and the repair strip 7;

[0042] The wire twisting mechanism 3 includes a wire twisting gear 31, which rotates relative to the cable 6, and the rotation axis of the wire twisting gear 31 is coaxial with the cable 6; the wire twisting gear 31 is provided with a wire passing hole 311 and a wire twisting gap 312, the wire passing hole 311 is used for allowing the free end of the repair strip 7 to pass through, and the wire twisting gap 312 is used for allowing the cable 6 to pass through. The rotation of the wire twisting gear 31 drives the repair strip 7 to be wrapped around the outside of the cable 6 and form a protective layer.

[0043] In order to solve the technical problem that the stability of the twisting device in the prior art is poor and it is easy to affect the accuracy and uniformity of the winding of the repair strip 7, the present technical solution proposes a high-stability twisting device for cables, such as Figures 1 to 7As shown, it includes a protective cover 1, a walking mechanism 2, a wire twisting mechanism 3 and a clamping mechanism 5; the walking mechanism 2, the wire twisting mechanism 3 and the clamping mechanism 5 are all installed inside the protective cover 1, and the clamping mechanism 5 and the wire twisting mechanism 3 are arranged in sequence along the wire twisting direction; the clamping mechanism 5 is used to clamp the fixed ends of the cable 6 and the repair strip 7; the wire twisting mechanism 3 includes a wire twisting gear 31, and the rotation of the wire twisting gear 31 drives the repair strip 7 to be wound around the outside of the cable 6 and form a protective layer.

[0044] In this technical solution, the wire twisting device is mounted on the cable 6 using the wire passing notch 11, and the walking mechanism 2 is used to realize the movement of the wire twisting device, that is, its forward and backward movement on the cable 6 drives the protective cover 1, the wire twisting mechanism 3 and the clamping mechanism 5 to move forward and backward, and in this process, the clamping mechanism 5 clamps the fixed ends of the cable 6 and the repair strip 7. The cable 6 passes through the wire twisting notch 312, and the free end of the repair strip 7 passes through the wire passing hole 311. The repair strip 7 is driven and wrapped around the outer periphery of the cable 6 under the action of the centrifugal force generated by the rotation of the wire twisting gear 31 to form a cable 6 with a protective layer.

[0045] This solution proposes a highly stable cable stranding device that utilizes a protective cover 1 to protect the traveling mechanism 2, stranding mechanism 3, and clamping mechanism 5. This prevents the stranding mechanism from shaking due to external factors such as wind and vibration, which could affect the stability of the stranding mechanism and the accuracy and uniformity of the winding of the repair strip 7. Furthermore, the provision of a wire-passing notch 11 not only allows the cable 6 and repair strip 7 to pass through, but also allows the heat generated during the operation of the traveling mechanism 2, stranding mechanism 3, and clamping mechanism 5 to be dissipated through the wire-passing notch 11, thereby extending the service life of the device.

[0046] The wire twisting gear 31 is provided with the wire passing hole 311 and the wire twisting notch 312 . The wire twisting notch 312 is provided at the lower end of the wire twisting gear 31 and extends to the center of the wire twisting gear 31 .

[0047] There are multiple wire-passing holes 311 , and the multiple wire-passing holes 311 are circumferentially distributed around the twisted wire gap 312 . The rotation of the twisted wire gear 31 drives the repair strip 7 to be wound around the outer circumference of the cable 6 .

[0048] Since there are multiple wire holes 311 and the wire holes 311 are circumferentially distributed around the twisted wire notch 312 , it is beneficial for the repair strip 7 to be evenly wound around the cable 6 to form a tight protective layer.

[0049] It should be noted that the walking mechanism 2 is a common technical means for those skilled in the art. Those skilled in the art can purchase different types of walking mechanisms 2 on the market, and those skilled in the art can select and assemble them according to their needs. This embodiment will not provide a specific description of the walking mechanism 2.

[0050] To further illustrate, the cross-sectional shape of the protective cover 1 is any one of a circle and a rectangle.

[0051] When the shape of the protective cover 1 is limited to a circle, the circular shape of the protective cover 1 has higher stability, can evenly disperse external wind and vibration, reduce stress concentration caused by the irregular shape, thereby improving the stability of the entire wire twisting device during operation, and further improving the accuracy and uniformity of the wire twisting. When the shape of the protective cover is limited to a rectangle, the rectangular shape of the protective cover 1 facilitates flexible adjustment of the position of the internal components according to the direction of the cable or the installation requirements of the equipment.

[0052] Preferably, the maximum opening of the wire notch 11 is 1 / 4 to 1 / 3 of the diameter of the protective cover 1, which helps maintain the stability of the cable 6 during the twisting process and reduces the uneven twisting caused by the shaking of the cable 6. At the same time, it also helps to make the twisting device applicable to cables 6 of different diameters, thereby improving the versatility and applicability of the device.

[0053] To further illustrate, the material of the protective cover 1 is transparent material.

[0054] This technical solution limits the material of the protective cover 1, which facilitates the operator to visually observe the working status of the wire twisting mechanism 3 and the winding status of the repair strip 7. On the one hand, it facilitates the timely discovery and resolution of problems, improves work efficiency and safety, and on the other hand, helps to ensure the accuracy and uniformity of the twisted wire. It should be noted that the material of the protective cover 1 can be polymethyl methacrylate, which is not limited here.

[0055] Further, the wire twisting mechanism 3 further includes a wire twisting mounting plate 32 and a wire twisting drive assembly; the wire twisting mounting plate 32 is mounted inside the protective cover 1, and a relief notch 321 is formed at the bottom of the wire twisting mounting plate 32 and is interconnected with the wire twisting notch 312, and the relief notch 321 is used to avoid the cable 6;

[0056] The wire twisting mounting plate 32 has a hollow structure formed therein, and the wire twisting gear 31 is rotatably mounted on the wire twisting mounting plate 32 through the hollow structure, and the front end of the wire twisting gear 31 protrudes from the front side wall of the wire twisting mounting plate 32;

[0057] The wire twisting drive assembly is mounted on the wire twisting mounting plate 32 , and an output end of the wire twisting drive assembly is connected to the wire twisting gear 31 . The wire twisting drive assembly is used to drive the wire twisting gear 31 to rotate.

[0058] This technical solution utilizes a twisting mounting plate 32 and a twisting drive assembly. During the twisting process, the twisting drive assembly activates and drives the twisting gear 31 to rotate. The cable 6 passes through the twisting notch 312. Simultaneously, the repair strip 7 passes through the wire hole 311 in the twisting gear 31. As the twisting gear 31 rotates, the repair strip 7 is driven by centrifugal force and wrapped around the outer circumference of the cable 6. Furthermore, precise control of the twisting drive assembly ensures that the rotation speed and direction of the twisting gear 31 meet the requirements, thereby achieving precise winding of the repair strip 7.

[0059] Further description, the wire twisting drive assembly includes a first transmission gear 33, a second transmission gear 34, a third transmission gear 35, a fourth transmission gear 36, a belt 37 and a wire twisting driver 38. The first transmission gear 33 and the second transmission gear 34 are rotatably mounted on the wire twisting mounting plate 32. The first transmission gear 33 and the second transmission gear 34 are both engaged with the wire twisting gear 31. The first transmission gear 33 and the second transmission gear 34 are respectively located on the upper and lower sides of the wire twisting gear 31. The rotation of the first transmission gear 33 and the second transmission gear 34 is used to jointly drive the rotation of the wire twisting gear 31.

[0060] The third transmission gear 35 is coaxial with the first transmission gear 33, and the fourth transmission gear 36 is coaxial with the second transmission gear 34. The third transmission gear 35 and the first transmission gear 33 are respectively located on the front and rear sides of the lower side wall of the twisted wire mounting plate 32, and the fourth transmission gear 36 and the second transmission gear 34 are respectively located on the front and rear sides of the upper side wall of the twisted wire mounting plate 32.

[0061] The belt 37 is sleeved on the outside of the third transmission gear 35 and the fourth transmission gear 36. The third transmission gear 35 and the first transmission gear 33 are both connected to the output end of the wire twisting driver 38. The wire twisting driver 38 is used to drive the rotation of the third transmission gear 35 and the first transmission gear 33. The third transmission gear 35 drives the rotation of the fourth transmission gear 36 and the second transmission gear 34 through the belt 37.

[0062] A wire twisting notch 312 is provided on the wire twisting gear 31. When the wire twisting notch 312 rotates to below the first transmission gear 33, the second transmission gear 34 can drive the wire twisting gear 31 to continue rotating. Similarly, when the wire twisting notch 312 rotates to below the second transmission gear 34, the first transmission gear 33 can drive the wire twisting gear 31 to continue rotating, thereby ensuring the smooth progress of the wire twisting process.

[0063] Because the first and third transmission gears 33 and 35 are coaxially arranged, the output end of the wire twisting drive 38 can simultaneously drive the third and first transmission gears 35 and 33 to rotate. At this point, the third transmission gear 35 drives the belt 37, which in turn drives the fourth transmission gear 36, which in turn drives the second transmission gear 34, which in turn drives the wire twisting gear 31. Simultaneously, the first transmission gear 33 also drives the wire twisting gear 31, making the entire wire twisting drive assembly more compact and space-saving, thus saving space.

[0064] Further description, it also includes a wire twisting front and rear position adjustment mechanism 4, which is installed inside the protective cover 1, and the wire twisting mechanism 3 is installed on the wire twisting front and rear position adjustment mechanism 4. The wire twisting mechanism 3 moves forward and backward relative to the protective cover 1 through the wire twisting front and rear position adjustment mechanism 4.

[0065] By setting up a front and rear position adjustment mechanism 4 for the twisted wire, the twisted wire mechanism 3 is allowed to move forward and backward relative to the protective cover 1, so that the position of the twisted wire structure 3 can be adjusted according to cables 6 of different lengths, diameters and types, ensuring that the twisting process is always carried out in the optimal position, thereby improving the versatility of the equipment and the uniformity and accuracy of the winding of the repair strip 7.

[0066] Further description, the twisted wire front and rear position adjustment mechanism 4 includes a mounting frame 41 and a position adjustment drive assembly, the mounting frame 41 is installed inside the protective cover 1, and the twisted wire mounting plate 32 is mounted on the mounting frame 41 so as to be movable forward and backward;

[0067] The position adjustment drive assembly is installed on the mounting bracket 41 , and an output end of the position adjustment drive assembly is connected to the twisted wire mounting plate 32 . The position adjustment drive assembly is used to drive the twisted wire mounting plate 32 to move forward and backward.

[0068] By setting up the mounting frame 41 and the position adjustment drive assembly, the position adjustment drive assembly is used to drive the wire twisting mounting plate 32 to move forward and backward, thereby realizing the forward and backward movement of the wire twisting mechanism 3 and realizing the precise adjustment of the position of the wire twisting mechanism 3 to meet different work requirements.

[0069] To further illustrate, the mounting frame 41 includes front and rear guide rods 411 and a vertical plate 412;

[0070] There are at least two vertical plates 412, which are symmetrically mounted on both sides of the interior of the protective cover 1 along the front-to-back direction. The vertical plates 412 are provided with receiving notches 4121 for the cables 6 and the repair strips 7 to pass through.

[0071] There are at least four front and rear guide rods 411, which are evenly installed between the two vertical plates 412, with two front and rear guide rods 411 located on the left side of the vertical plates 412 and the remaining two front and rear guide rods 411 located on the right side of the vertical plates 412.

[0072] The twisted wire mounting plate 32 is movably mounted on the front and rear guide rods 411 .

[0073] By providing the front and rear guide rods 411 and the vertical plate 412, the mounting frame 41 forms a stable support frame, which not only ensures the stability of the twisting mechanism 3 during movement but also reduces deviation caused by vibration or external forces, thereby improving the accuracy and uniformity of the winding of the repair strip 7. The twisting mounting plate 32 is movably mounted on the front and rear guide rods 411, allowing the twisting mechanism 3 to be precisely adjusted along the front and rear guide rods 411 as needed, allowing the twisting device to adapt to cables 6 of different lengths or different working scenarios, thereby improving the versatility and practicality of the device.

[0074] In addition, the accommodating notch 4121 opened on the vertical plate 412 provides a convenient passage for the cable 6 to pass through, ensuring that the cable 6 can smoothly enter and leave the twisted wire area during the twisting process, thereby improving the smoothness and efficiency of the operation.

[0075] Further explanation, the position adjustment drive assembly also includes a front and rear adjustment driver 42, a front and rear drive rod 43 and a front and rear transmission block;

[0076] The front-to-back adjustment driver 42 is mounted on one of the vertical plates 412, and the front-to-back drive rod 43 is mounted between the two vertical plates 412. The front-to-back drive rod 43 is parallel to the front-to-back guide rod 411, and the ends of the front-to-back drive rod 43 are connected to the output end of the front-to-back adjustment driver 42. The front-to-back transmission block is movably mounted on the front-to-back drive rod 43, and the front-to-back adjustment driver 42 is used to drive the front-to-back transmission block to move forward and backward.

[0077] The front and rear transmission blocks are detachably mounted on the twisted wire mounting plate 32 .

[0078] In a preferred embodiment of the present technical solution, the front and rear transmission blocks move forward and backward along the front and rear drive rods 43 to drive the twisted wire mounting plate 32 to move forward and backward along the extension direction of the front and rear guide rods 411, thereby realizing the adjustment of the horizontal displacement of the twisted wire mechanism 3 relative to the protective cover 1, which is simple and quick.

[0079] Further explanation: the clamping mechanism 5 includes a clamping seat 51 and at least two clamping blocks 52, and the clamping seat 51 is installed inside the protective cover 1;

[0080] The two clamping blocks 52 are movably installed on the bottom of the clamping seat 51 to the left and right, and the clamping blocks 52 are provided with a repair strip clamping notch 521 and a cable clamping notch 522, and the repair strip clamping notch 521 is located on the outside of the cable clamping notch 522; the shape of the repair strip clamping notch 521 matches the repair strip 7, and the repair strip clamping notch 521 is used to accommodate the fixed end of the repair strip 7; the cable clamping notches 522 of the two clamping blocks 52 form a clamping area for accommodating the cable 6, and the shape of the clamping area matches the cable 6.

[0081] By providing the clamping seat 51 and the clamping block 52, and utilizing the repair strip clamping notch 521 to accommodate the fixed end of the repair strip 7, the repair strip 7 can be effectively secured and tightened during the twisting process. The cable clamping notches 522 of the two clamping blocks 52 form a clamping area for accommodating the cable 6, thereby clamping and securing the cable 6. Furthermore, the distance between the two clamping blocks 52 can be adjusted according to the size and shape of the cable 6 to accommodate different clamping requirements, thereby improving the applicability of the device.

[0082] Preferably, the clamping mechanism 5 also includes a bidirectional movable driver 53, which is located between the clamping seat 51 and the clamping block 52. The two clamping blocks 52 are respectively connected to the two output ends of the bidirectional movable driver 53, and the bidirectional movable driver 53 is used to drive the two clamping blocks 52 to synchronously approach and move away from each other in the left and right directions.

[0083] By providing a bidirectional moving driver 53 , the two clamping blocks 52 can be moved toward and away from each other synchronously in the left and right directions, which is beneficial for saving space.
