Description

Technical Field

[0001] The utility model relates to the field of wire twisting devices, in particular to a retractable 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] However, since the traveling mechanism is usually immovable relative to the frame and is usually installed in front of the twisting mechanism in the direction of the twisting, a space must be reserved between the traveling mechanism and the twisting mechanism for the repair strip to wind freely during the winding process. This is to prevent the distance between the traveling mechanism and the twisting mechanism from being too small when the twisting mechanism rotates, making it difficult to wind the repair strip. However, leaving space between the traveling mechanism and the twisting mechanism for the repair strip to wind freely will make the frame too long and too large. This not only makes it difficult to hang the twisting device on the cable, but also easily puts additional pressure on the cable itself, increasing the possibility of cable damage.

DETAILED DESCRIPTION

[0047] 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.

[0048] The present technical solution provides a retractable cable twisting device, comprising a frame 1, a first traveling mechanism 2, a second traveling mechanism 3, a twisting mechanism 4, a traveling position adjusting mechanism 5 and a clamping mechanism 6;

[0049] The bottom of the frame 1 is provided with a wire-passing notch 11 for the cable 8 and the repair strip 9 to pass through; the second walking mechanism 3, the clamping mechanism 6, the twisting mechanism 4 and the first walking mechanism 2 are sequentially installed inside the frame 1 along the twisting direction, and the first walking mechanism 2 and the second walking mechanism 3 are used to move forward and backward along the extension direction of the cable 8;

[0050] The travel position adjustment mechanism 5 is installed between the frame 1 and the first travel mechanism 2. The first travel mechanism 2 moves forward and backward relative to the frame 1 through the travel position adjustment mechanism 5. The second travel mechanism 3 and the frame 1 are relatively stationary. The forward and backward movement of the first travel mechanism 2 and the second travel mechanism 3 drives the forward and backward movement of the frame 1, the wire twisting mechanism 4, the travel position adjustment mechanism 5 and the clamping mechanism 6.

[0051] The clamping mechanism 6 is used to clamp the fixed ends of the cable 8 and the repair strip 9;

[0052] The wire twisting mechanism 4 includes a wire twisting gear 41, which rotates relative to the cable 8, and the rotation axis of the wire twisting gear 31 is coaxial with the cable 8; the wire twisting gear 41 is provided with a wire passing hole 411 and a wire twisting gap 412, the wire passing hole 411 is used for allowing the free end of the repair strip 9 to pass through, and the wire twisting gap 412 is used for allowing the cable 8 to pass through, and the rotation of the wire twisting gear 41 drives the repair strip 9 to be wrapped around the outside of the cable 8 and form a protective layer.

[0053] In order to solve the technical problem that the length and volume of the frame 1 in the prior art are too long, which not only makes it difficult to hoist the twisting device on the cable 8, but also easily causes additional burden on the cable 8 itself and increases the possibility of damage to the cable 8, the present technical solution proposes a retractable twisting device for the cable, such as Figures 1 to 9 As shown, it includes a frame 1, a first traveling mechanism 2, a second traveling mechanism 3, a twisting mechanism 4, a traveling position adjustment mechanism 5 and a clamping mechanism 6; a wire-passing notch 11 is provided at the bottom of the frame 1 for the cable 8 and the repair strip 9 to pass through, and the second traveling mechanism 3, the clamping mechanism 6, the twisting mechanism 4 and the first traveling mechanism 2 are installed forward in sequence inside the frame 1 along the twisting direction; the clamping mechanism 6 is used to clamp the fixed end of the cable 8 and the repair strip 9; the twisting mechanism 4 includes a twisting gear 41, and the twisting gear 41 is provided with a wire-passing hole 411 and a twisting notch 412. The wire-passing hole 411 is used for the free end of the repair strip 9 to pass through, and the twisting notch 412 is used for the cable 8 to pass through. The rotation of the twisting gear 41 drives the repair strip 9 to wrap around the outside of the cable 8 and form a protective layer.

[0054] The working principle of this technical solution is: the first walking mechanism 2 is adjusted to the inside of the frame 1 through the walking position adjustment mechanism 5 to obtain a telescopic wire twisting device, and the telescopic wire twisting device is mounted on the cable 8 using the wire passing notch 11, and then the first walking mechanism 2 is extended to the outside of the frame 1 using the walking position adjustment mechanism 5 to obtain an unfolded wire twisting device. After that, the forward and backward movement of the first walking mechanism 2 and the second walking mechanism 3 drives the forward and backward movement of the frame 1, the wire twisting mechanism 4, the walking position adjustment mechanism 5 and the clamping mechanism 6, and in this process the clamping mechanism 6 clamps the fixed ends of the cable 8 and the repair strip 9, the cable 8 passes through the wire twisting notch 412, and the free end of the repair strip 9 passes through the wire passing hole 411. The repair strip 9 is driven and wrapped around the outside of the cable 8 under the action of the centrifugal force generated by the rotation of the wire twisting gear 41 to form a protective layer. This solution proposes a retractable cable twisting device, which uses a travel position adjustment mechanism 5 to adjust the position of the first travel mechanism 2 relative to the frame 1, so that even if the length of the frame 1 is small (that is, the volume is small), the repair strip 9 can be smoothly wound around the outside of the cable 8, thereby helping to reduce the volume of the twisting device. The smaller volume of the twisting device not only helps to reduce the difficulty of hanging the twisting device, but also reduces the possibility of damage to the cable 8.

[0055] It should be noted that, since the second traveling mechanism 3 is located on one side of the fixed end of the repair strip 9 and has no effect on the free winding of the repair strip 9 , the second traveling mechanism 3 in this technical solution does not need to be specially provided with a traveling position adjustment mechanism 5 .

[0056] It should be further explained that the first walking mechanism 2 and the second walking mechanism 3 are common technical means for those skilled in the art. Those skilled in the art can purchase different types of first walking mechanisms 2 and second walking mechanisms 3 on the market. Those skilled in the art can choose and assemble them according to their needs. The present utility model will no longer provide a specific description of the first walking mechanism 2 and the second walking mechanism 3.

[0057] Preferably, the wire twisting gear 41 is provided with the wire passing hole 411 and the wire twisting notch 412, and the wire twisting notch 412 is provided at the end of the wire twisting gear 41 and extends to the center of the wire twisting gear;

[0058] There are multiple wire passing holes 411 , and the multiple wire passing holes 411 are circumferentially distributed around the twisted wire notch 412 .

[0059] Since there are multiple wire holes 411 and the wire holes 411 are circumferentially distributed around the twisted wire notch 412 , it is beneficial for the repair strip 9 to be evenly wound around the cable 8 to form a tight protective layer.

[0060] Further description, the walking position adjustment mechanism 5 includes a movable guide block 51 and a movable guide rail 52, the movable guide block 51 is protrudingly mounted on the inner top wall of the frame 1; the movable guide rail 52 is mounted on the top of the first walking mechanism 2;

[0061] The bottom surface of the movable guide block 51 is provided with a movable guide groove matching the movable guide rail 52;

[0062] The movable guide rail 52 is slidably connected to the movable guide groove and moves along the extending direction of the movable guide block 51 .

[0063] The combination of the movable guide block 51 and the movable guide rail 52 enables the first traveling mechanism 2 to move forward and backward inside the frame 1 , which is simple and efficient.

[0064] Further description, the walking position adjustment mechanism 5 further includes a moving driver 53, a moving gear 54 and a moving rack 55, the output end of the moving driver 53 is connected to the moving gear 54, and the moving driver 53 is used to drive the rotation of the moving gear 54;

[0065] The moving rack 55 is installed at the bottom of the moving guide rail 52, and the moving rack 55 is located behind the first walking mechanism 2. The moving rack 55 is engaged with the moving gear 54. The rotation of the moving gear 54 drives the moving guide rail 52 to move forward and backward through the moving rack 55.

[0066] When the position of the first walking mechanism 2 needs to be adjusted, the moving driver 53 is started, and the moving driver 53 drives the moving gear 54 to rotate. The rotating moving gear 54 engages with the moving rack 55, driving the moving rack 55 to move linearly in the front and rear directions. The movement of the moving rack 55 drives the movement of the moving guide rail 52, and the movement of the moving guide rail 52 drives the movement of the first walking mechanism 2, thereby realizing the adjustment of the position of the first walking mechanism 2 inside the frame 1. The adjustment method is simple and efficient.

[0067] Further description, the two movable guide blocks 51 and the one movable guide rail 52 constitute a set of adjustment components, and the number of the adjustment components is at least two, and the two sets of adjustment components are symmetrically installed on the top of the first walking mechanism 2;

[0068] The movable rack 55 is installed at the bottom of any one of the adjustment components.

[0069] When the movable rack 55 moves forward, the movement of the movable rack 55 drives the movement of an adjustment assembly mounted thereon, which in turn drives the movement of the first traveling mechanism 2, which in turn drives the movement of another adjustment assembly mounted on top of the first traveling mechanism 2, thereby achieving movement of two sets of adjustment assemblies. Furthermore, by providing two sets of adjustment assemblies, the stability of the system is increased and the risk of failure due to unbalanced loading is reduced.

[0070] Further description, the wire twisting mechanism 4 also includes a wire twisting mounting plate 42 and a wire twisting drive assembly; the wire twisting mounting plate 42 is installed inside the frame 1, and a hollow structure is provided inside the wire twisting mounting plate 42. The wire twisting gear 41 is rotatably mounted on the wire twisting mounting plate 42 through the hollow structure, and the front end of the wire twisting gear 41 protrudes from the front side wall of the wire twisting mounting plate 42; the bottom of the wire twisting mounting plate 42 is provided with an avoidance gap 421 that is interconnected with the wire twisting gap 412, and the avoidance gap 421 is used to avoid the cable 8;

[0071] The wire twisting drive assembly is mounted on the wire twisting mounting plate 42 , and an output end of the wire twisting drive assembly is connected to the wire twisting gear 41 . The wire twisting drive assembly is used to drive the wire twisting gear 41 to rotate.

[0072] This technical solution utilizes a wire-twisting mounting plate 42 and a wire-twisting drive assembly. During the twisting process, the wire-twisting drive assembly activates and drives the wire-twisting gear 41 to rotate. The cable 8 passes through the wire-twisting notch 412 in the center of the wire-twisting gear. Simultaneously, the repair strip 9 passes through the wire-passing hole 411 in the wire-twisting gear. As the wire-twisting gear 41 rotates, the repair strip 9 is driven by centrifugal force and wrapped around the outside of the cable 8. Furthermore, precise control of the wire-twisting drive assembly ensures that the rotational speed and direction of the wire-twisting gear 41 meet the requirements, thereby achieving precise winding of the repair strip 9.

[0073] Further description, the wire twisting drive assembly includes a first transmission gear 43, a second transmission gear 44, a third transmission gear 45, a fourth transmission gear 46, a belt 47 and a wire twisting driver 48. The first transmission gear 43 and the second transmission gear 44 are both rotatably mounted on the wire twisting mounting plate 42. The first transmission gear 43 and the second transmission gear 44 are both engaged with the wire twisting gear 41. The first transmission gear 43 and the second transmission gear 44 are respectively located on the upper and lower sides of the wire twisting gear 41. The rotation of the first transmission gear 43 and the second transmission gear 44 is used to jointly drive the rotation of the wire twisting gear 41.

[0074] The third transmission gear 45 is coaxially arranged with the first transmission gear 43, and the fourth transmission gear 46 is coaxially arranged with the second transmission gear 44. The third transmission gear 45 and the first transmission gear 43 are respectively located on the front and rear sides of the lower side wall of the twisted wire mounting plate 42, and the fourth transmission gear 46 and the second transmission gear 44 are respectively located on the front and rear sides of the upper side wall of the twisted wire mounting plate 42.

[0075] The belt 47 is sleeved on the outside of the third transmission gear 45 and the fourth transmission gear 46. The third transmission gear 45 and the first transmission gear 43 are both connected to the output end of the wire twisting driver 48. The wire twisting driver 48 is used to drive the rotation of the third transmission gear 45 and the first transmission gear 43. The third transmission gear 45 drives the rotation of the fourth transmission gear 46 and the second transmission gear 44 through the belt 47.

[0076] Since the first transmission gear 43 and the third transmission gear 45 are coaxially arranged, the output end of the wire twisting driver 48 can simultaneously drive the third transmission gear 45 and the first transmission gear 43 to rotate. At this time, the third transmission gear 45 can drive the belt 47 to rotate, the belt 47 can drive the fourth transmission gear 46 to rotate, and the fourth transmission gear 46 can drive the second transmission gear 44 to rotate, so that the second transmission gear 44 can drive the wire twisting gear 41 to rotate.

[0077] In addition, a wire twisting notch 412 is provided on the wire twisting gear 41. When the wire twisting notch 412 rotates to below the first transmission gear 43, the second transmission gear 44 can drive the wire twisting gear 41 to continue rotating. Similarly, when the wire twisting notch 412 rotates to below the second transmission gear 44, the first transmission gear 43 can drive the wire twisting gear 41 to continue rotating, that is, the first transmission gear 43 and the second transmission gear 44 are used to alternately drive the rotation of the wire twisting gear 41, thereby ensuring the smooth progress of the wire twisting process.

[0078] Further description, it also includes a twisted wire front and rear position adjustment mechanism 7, the twisted wire front and rear position adjustment mechanism 7 is installed on the frame 1, the mobile driver 53 and the twisted wire mechanism 4 are both installed on the twisted wire front and rear position adjustment mechanism 7, and the twisted wire mechanism 4 can move forward and backward relative to the frame 1 through the twisted wire front and rear position adjustment mechanism 7;

[0079] The top of the twisted wire front and rear position adjustment mechanism 7 is provided with an avoidance groove for avoiding the walking position adjustment mechanism 5 .

[0080] By setting up a front and rear position adjustment mechanism 7 for the twisted wire, the twisted wire mechanism 4 is allowed to move forward and backward relative to the frame 1, so that the position of the twisted wire mechanism 4 can be adjusted according to cables 8 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 9.

The position adjustment drive assembly is used to drive the twisted wire mounting plate 42 to move forward and backward.

[0083] The twisted wire position adjustment mounting bracket 71 is provided with the avoidance groove, and the movable driver 53 is mounted on the twisted wire position adjustment mounting bracket 71 .

[0084] By setting up a wire twisting position adjustment mounting frame 71 and a position adjustment drive assembly, the position adjustment drive assembly is used to drive the wire twisting mounting plate 42 to move forward and backward, thereby realizing the forward and backward movement of the wire twisting mechanism 4 and achieving precise adjustment of the position of the wire twisting mechanism 4 to meet different work requirements.

[0085] To further illustrate, the twisted wire position adjustment mounting frame 71 includes front and rear guide rods 711 and a vertical plate 712;

[0086] There are at least two vertical plates 712 symmetrically mounted on both sides of the frame 1 along the front-to-back direction. The vertical plates 712 are provided with receiving notches 7121 for the cables 8 and the repair strips 9 to pass through.

[0087] There are at least four front and rear guide rods 711, which are evenly installed between the two vertical plates 712, with two front and rear guide rods 711 located on the left side of the vertical plates 712 and the remaining two front and rear guide rods 711 located on the right side of the vertical plates 712.

[0088] The twisted wire mounting plate 42 is movably mounted on the front and rear guide rods 711;

[0089] The vertical plate 712 is provided with the avoidance groove, and the moving driver 53 is installed on one of the vertical plates 712 .

[0090] By providing front and rear guide rods 711 and vertical plates 712, the wire twisting position adjustment mounting frame 71 forms a stable support frame, which not only ensures the stability of the wire twisting mechanism 4 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 9. The wire twisting mounting plate 42 is mounted on the front and rear guide rods 711 in a movable manner, allowing the wire twisting mechanism 4 to be precisely adjusted along the front and rear guide rods 711 as needed, allowing the wire twisting device to adapt to cables 8 of different lengths or different working scenarios, thereby improving the versatility and practicality of the device.

[0091] In addition, the accommodating notch 7121 opened on the vertical plate 712 provides a convenient passage for the cable 8 to pass through, ensuring that the cable 8 can smoothly enter and leave the twisted wire area during the twisting process, thereby improving the smoothness and efficiency of the operation.

[0092] Preferably, the position adjustment drive assembly further includes a front and rear adjustment driver 72, a front and rear drive rod 73 and a front and rear transmission block;

[0093] The front-to-back adjustment driver 72 is mounted on one of the vertical plates 712, and the front-to-back drive rod 73 is mounted between the two vertical plates 712. The front-to-back drive rod 73 is parallel to the front-to-back guide rod 711, and the ends of the front-to-back drive rod 73 are connected to the output end of the front-to-back adjustment driver 72. The front-to-back transmission block is sleeved on the front-to-back transmission rod 73 so as to be movable forward and backward. The front-to-back adjustment driver 72 is used to drive the front-to-back transmission block to move forward and backward.
