Description

Technical Field

[0001] The utility model relates to the field of wire twisting devices, in particular to a wire twisting device for cables. 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] When wrapping the repair strip around the cable using a twisting mechanism during the repair process, the cable and one end of the repair strip need to be clamped to facilitate wrapping. However, existing clamping mechanisms are not secure, causing the repair strip to loosen or slip during the wrapping process due to a lack of fixing points. This prevents the repair strip from fitting tightly around the cable, and the protective layer formed by the repair strip may be loose, failing to reinforce and protect the cable. Furthermore, existing clamping mechanisms cannot be adjusted to suit the type and diameter of the cable, resulting in poor adaptability of the twisting device. Utility Model Content

DETAILED DESCRIPTION

[0038] 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.

[0039] The present technical solution provides a twisting device for a cable, comprising a frame 1, a traveling mechanism 2, a twisting mechanism 3, and a clamping mechanism 4; the traveling mechanism 2, the twisting mechanism 3, and the clamping mechanism 4 are all mounted on the frame 1, and the clamping mechanism 4 and the twisting mechanism 3 are sequentially mounted inside the frame 1 along the twisting direction;

[0040] The clamping mechanism 4 includes a clamping seat 41 and at least two clamping assemblies 43; the clamping seat 41 is installed on the frame 1, the clamping assembly 43 is installed on the clamping seat 41, and the clamping assembly 43 moves left and right relative to the clamping assembly 43; the clamping assembly 43 is provided with a repair strip clamping notch 4331 and a cable clamping notch 4332, and the repair strip clamping notch 4331 is located outside the cable clamping notch 4332; the shape of the repair strip clamping notch 4331 matches the repair strip 8, and the repair strip clamping notch 4331 is used to accommodate the fixed end of the repair strip 8; the cable clamping notches 4332 of the two clamping assemblies 43 form a clamping area for accommodating the cable 7, and the shape of the clamping area matches the cable 7;

[0041] The wire twisting mechanism 3 includes a wire twisting gear 31, which rotates relative to the cable 7, and the rotation axis of the wire twisting gear 31 is coaxial with the cable 7; 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 to pass through, and the wire twisting gap 312 is used for allowing the cable 7 to pass through. The rotation of the wire twisting gear 31 drives the repair strip 8 to be wrapped around the outside of the cable 7 and form a protective layer.

[0042] In order to solve the technical problems that the clamping mechanism in the prior art has poor applicability and the protective layer formed by the repair strip 8 may be relatively loose and cannot play the role of reinforcing and protecting the cable, this technical solution proposes a twisting device for the cable, such as Figure 1-6 As shown, the device comprises a frame 1, a traveling mechanism 2, a twisting mechanism 3, and a clamping mechanism 4. The traveling mechanism 2, the twisting mechanism 3, and the clamping mechanism 4 are all mounted on the frame 1, and the clamping mechanism 4 and the twisting mechanism 3 are sequentially mounted inside the frame 1 along the twisting direction. The traveling mechanism 2 in this technical solution is used to realize the movement of the twisting device, that is, its forward and backward movement on the cable 7 drives the frame 1, the twisting mechanism 3, and the clamping mechanism 4 to move forward and backward along the extension direction of the cable 7. At this time, the clamping notch 4331 of the repair strip clamps the fixed end of the repair strip 8, and the clamping area clamps the cable. The cable 7 passes through the twisting notch 312, and the free end of the repair strip 8 passes through the wire hole 311. Under the action of the centrifugal force generated by the rotation of the twisting gear 31, the repair strip 8 is driven and wrapped around the outer periphery of the cable 7 to form a protective layer. Because in this process, this solution uses the repair strip clamping notch 4331 to clamp the fixed end of the repair strip 8, and the clamping area clamps the cable line, it can effectively ensure that the repair strip 8 is fixed and tightened during the twisting process, so that the protective layer formed by the repair strip can fit tightly to the outside of the cable line 7, ensuring the reinforcement and protection of the cable line 7.

[0043] Furthermore, the clamping mechanism 4 includes a clamping seat 41 and at least two clamping assemblies 43; the clamping seat 41 is installed on the frame 1; the clamping assembly 43 is installed on the clamping seat 41, and the clamping assembly 43 moves left and right relative to the clamping assembly 43, and a clamping area for clamping the cable 7 is formed between the cable clamping notches 4332 of the two clamping assemblies 43, so that the distance between the two clamping assemblies 43 can be adjusted according to the type and diameter of the cable, which can adapt to different clamping requirements, thereby improving the applicability of the device.

[0044] Preferably, the wire gap 312 is opened at the lower end of the wire gear 31 and extends to the center of the wire gear 31; there are multiple wire holes 311, and the multiple wire holes 311 are circumferentially distributed around the wire gap 312, and the rotation of the wire gear 31 drives the repair strip to wrap around the outer periphery of the cable 7.

[0045] Since there are multiple through holes 311 and the through holes 311 are circumferentially distributed around the twisted wire notches 312 , it is beneficial for the repair strip to be evenly wound around the cable 7 to form a tight protective layer.

[0046] Further description, the clamping mechanism 4 also includes a clamping guide rail 42, and the clamping guide rail 42 is located between the clamping seat 41 and the clamping assembly 43. The upper surface of the clamping assembly 43 is provided with a clamping guide groove matching the clamping guide rail 42. The clamping assembly 43 is connected to the clamping guide rail 42 through the clamping guide groove, and the clamping assembly 43 moves left and right along the clamping guide rail 42.

[0047] By providing the clamping guide rail 42 , the clamping assembly 43 can be moved left and right via the clamping guide rail 42 , and the movement method is simple and efficient.

[0048] Further, the clamping assembly 43 includes a clamping guide block 431, a clamping sliding block 432, and a clamping block 433 connected in sequence from top to bottom. The clamping guide block 431 is located at the bottom of the clamping seat 41, and the clamping guide groove is formed on the upper surface of the clamping guide block 431. The clamping guide block 431 is slidably connected to the clamping guide rail 42 through the clamping guide groove.

[0049] The clamping block 433 is provided with the repair strip clamping notch 4331 and the cable clamping notch 4332 . The cable clamping notches 4332 of the two clamping blocks 433 are used to form the clamping area.

[0050] This technical solution further improves the performance and service life of the clamping assembly and ensures the clamping effect and quality by providing the clamping guide block 431 , the clamping sliding block 432 and the clamping block 433 .

[0051] Further description, the clamping mechanism further includes a forward and reverse threaded rod 44 and a clamping drive member 45, the forward and reverse threaded rod 44 is rotatably mounted on the bottom of the clamping seat 41, and the forward and reverse threaded rod 44 and the clamping guide rail 42 are parallel to each other;

[0052] Both ends of the forward and reverse threaded rod 44 are respectively provided with external threads with opposite rotation directions, and the clamping sliding block 432 is provided with an internal thread. The clamping sliding blocks 432 of the two clamping assemblies 43 are respectively threadedly connected to the two ends of the forward and reverse threaded rod 44, and the rotation of the forward and reverse threaded rod 44 is used to drive the two clamping sliding blocks 432 to move closer to and away from each other.

[0053] The clamping drive member 45 is installed at the bottom of the clamping seat 41 , and the output end of the clamping drive member 45 is connected to the forward and reverse threaded rod 44 . The clamping drive member 45 is used to drive the forward and reverse threaded rod 44 to rotate.

[0054] By setting the forward and reverse threaded rods 44 and the clamping drive 45, automatic spacing adjustment between the two clamping components 43 is achieved, and the distance between the two clamping components 43 can be quickly adjusted according to the actual size of the cable 7, thereby improving work efficiency and flexibility.

[0055] It is further explained that the wire twisting mechanism includes a wire twisting mounting frame 32 and a wire twisting drive assembly; the wire twisting mounting frame 32 is mounted on the frame 1, and the wire twisting gear 31 is rotatably mounted on the wire twisting mounting frame 32; the wire twisting drive assembly is mounted on the wire twisting mounting frame 32, and the output end of the wire twisting drive assembly is connected to the wire twisting gear 31, and the wire twisting drive assembly is used to drive the rotation of the wire twisting gear 31.

[0056] This technical solution utilizes a twisting gear 31 and a twisting mounting bracket 32. During the twisting process, the twisting drive assembly activates and drives the twisting gear 31 to rotate. The cable 7 passes through the twisting notch 312 in the center of the twisting gear 31. Simultaneously, the repair strip 8 is twisted through the wire hole 311 on the twisting gear 31. As the twisting gear 31 rotates, the repair strip 8 is driven by centrifugal force and wrapped around the outer circumference of the cable 7. 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 8.

[0057] 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 both rotatably mounted on the wire twisting mounting frame 32, and the first transmission gear 33 is meshed with the wire twisting gear 31, and the second transmission gear 34 is meshed 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.

[0058] 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 at the front and rear sides of the lower end of the wire twisting mounting frame 32, and the fourth transmission gear 36 and the second transmission gear 34 are respectively located at the front and rear sides of the upper end of the wire twisting mounting frame 32.

[0059] 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, and the third transmission gear 35 drives the rotation of the fourth transmission gear 36 and the second transmission gear 34 through the belt 37.

[0060] The wire twisting gear 31 is provided with a wire twisting notch 312. When the wire twisting notch 312 rotates 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 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. In addition, the first transmission gear 33 and the second transmission gear 34 are respectively located on both sides of the wire twisting gear 31, so that the wire twisting device can better adapt to the wire twisting requirements under different working conditions.

[0061] 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 can drive 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.

[0068] The front and rear adjustment power device 53 and the front and rear drive rod 54 are both mounted on the frame 1, and the front and rear drive rod 54 is parallel to the front and rear adjustment guide rail 51.

The front and rear adjustment power device 53 is used to drive the front and rear transmission block 55 to move forward and backward.

[0069] The front and rear transmission blocks 55 are detachably mounted on the twisted wire mounting bracket 32 .

[0070] In a preferred embodiment of the present technical solution, the front and rear transmission blocks 55 move forward and backward along the front and rear drive rods 54, driving the twisted wire mounting frame 32 to move forward and backward along the extension direction of the front and rear adjustment guide rails 51, thereby realizing the adjustment of the horizontal displacement of the front and rear position adjustment mechanism 5 relative to the frame 1, which is simple and quick.

[0079] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0080] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0081] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0082] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
