Description

Technical Field

[0001] This utility model belongs to the field of cable production equipment, and in particular relates to a cable pulling device for optical-electric composite cables. Background Technology

[0002] In the cable cabling process, under the action of the stranding device, the cable core is stranded with a certain central axis as a reference, according to a certain helical angle and pitch. The traction device pulls the stranded cable core forward at a certain speed, the wrapping device wraps the cable core simultaneously, and finally the take-up device winds the cable core into a coil.

[0003] In the cable winding process, tracked traction machines are often used as traction devices. These machines have guiding and positioning mechanisms in the cable entry and exit directions. For example, Chinese utility model patent CN218968458U discloses a tracked traction machine for cable winding, which includes a tracked traction machine with fixed plates on both sides. A positioning structure is slidably installed on the side of the two fixed plates that is far apart from each other, and a drive structure is fixedly installed on the side of the two fixed plates that is far apart from each other. This device's positioning mechanism uses a center-driven, enclosed design, which is not conducive to quickly completing the next cable routing and passing. Chinese utility model patent CN201473108U discloses a tracked traction machine with a design using two vertical positioning rods. While this facilitates cable routing and passing, the positioning mechanism often uses a fixed and non-removable / non-foldable design, which is not conducive to transfer and handling.

[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Examples, such as Figures 1-7As shown, the present invention provides a photoelectric composite cable forming and traction device, including a tracked traction machine 1. The tracked traction machine 1 is provided with a positioning mechanism 2 on both the inlet and outlet sides. The positioning mechanism 2 includes a mounting base 21 connected to the side of the tracked traction machine 1 by screws. A folding plate 22 is provided on one side of the mounting base 21 and connected to it by bolts 212. The folding plate 22 includes a plate body 221. Two connecting ears 222 are provided on the plate body 221. A central shaft 23 is provided through the center of the two connecting ears 222. A roller sleeve 24 is provided on the central shaft 23 between the two connecting ears 222. A rotating plate 25 is provided between the end face of the roller sleeve 24 and the end face of the connecting ears 222. A connecting sleeve 26 is provided in the tangential direction of the rotating plate 25. A positioning shaft 27 is provided in the connecting sleeve 26. A bushing 28 is provided on the positioning shaft 27. A limiting nut 29 for limiting the axial movement of the bushing 28 is provided on the top of the positioning shaft 27. Among them, the roller sleeve 24 can rotate around the central axis 23 when it comes into contact with the passively traction optical-electric composite cable, which provides a certain support for the optical-electric composite cable; the bushing 28 can rotate continuously around the positioning axis 27, which provides positioning and guidance for the optical-electric composite cable passing through the traction direction of the tracked traction machine 1.

[0017] Specifically, the mounting base 21 serves as the mounting foundation for the positioning mechanism 2 and provides a turning center for the folding plate 22, i.e., the center where the bolt 212 is located; the rotating plate 25 and the connecting sleeve 26 are an integral structure, and the connecting sleeve 26 provides a mounting center for the positioning shaft 27. A bottom cap is provided at the bottom of the positioning shaft 27 and is threadedly connected to it. The bottom cap is also radially connected to the positioning shaft 27 through a positioning pin to ensure that the movements of the positioning shaft 27, the rotating plate 25 and the connecting sleeve 26 are synchronized. Furthermore, this utility model achieves folding and unfolding functions by employing a foldable positioning mechanism 2. In its folded state, it can be flipped to the empty space below the tracked tractor 1 without extending too much space, facilitating the transfer and handling of the equipment. When the positioning mechanism 2 is fully unfolded, it can guide and position the optoelectronic composite cable passing through the equipment. Moreover, by manually folding a portion of the structure, namely the synchronously operating combination structure consisting of the positioning shaft 27, the rotating plate 25, the connecting sleeve 26, and the bushing 28, the positioning area of ​​the positioning mechanism 2 is opened, making it easier to pull new cables into place, especially thicker optoelectronic composite cables. For lighter optoelectronic composite cables, they can be directly lifted and pulled into the positioning range of the positioning mechanism 2.

[0018] To improve the folding performance of the positioning mechanism 2, the rotating plate 25 provided by this utility model is provided with an eccentrically distributed guide post 210 on one side. The guide post 210 cooperates with the guide groove 223 provided on the end face of the connecting ear 222. The guide groove 223 is C-shaped. The connecting ear 222 is provided with a mounting groove 224 on the side facing away from the rotating plate 25. A circumferential limiting member 3 that cooperates with the guide post 210 is provided in the mounting groove 224. The circumferential limiting member 3 is connected to the central shaft 23 by a key 213. The central angle corresponding to the arc length of the guide groove 223 is 180 degrees. After manually operating the circumferential limiting member 3 and engaging it with the guide post 210, the guide post 210 is located at the top end of the guide groove 223, which can realize the positioning of the rotating plate 25, thereby enabling the positioning shaft 27 to maintain a stable vertical state and achieve stable and reliable positioning and guiding functions. Conversely, by manually operating the circumferential limiting member 3 and releasing it from engagement with the guide post 210, the guide post 210 is located at the bottom end of the guide groove 223, which can realize the folding of the positioning shaft 27, allowing the positioning shaft 27, the rotating plate 25 and the connecting sleeve 26 to be folded synchronously to the position corresponding to the surface of the folding plate 22.

[0019] To improve the fit between the circumferential limiting component 3 and the guide post 210, the circumferential limiting component 3 provided by this utility model includes a comma-shaped limiting block 31. The arc formed by the end of the comma of the limiting block 31 is used to engage the guide post 210. The maximum center distance between the head of the comma of the limiting block 31 and the central axis 23 is less than the minimum center distance of the guide groove 223, thereby ensuring that the limiting block 31 does not affect the complete entry of the guide post 210 into the bottom end of the guide groove 223. Furthermore, the limiting block 31 provided by this utility model is disposed on the groove cover 32. A spring 33 is disposed inside the groove cover 32. One end of the spring 33 is disposed with an end cap 34 connected to the central axis 23. A positioning plate 35 parallel to the side of the folding plate 22 is disposed on the outside of the groove cover 32. A positioning post 36 is disposed on the positioning plate 35, and the positioning post 36 engages with the positioning hole 227 disposed on the side of the folding plate 22. The length of the guide post 210 is equal to the thickness of the middle part of the connecting ear 222 plus the thickness of the limiting block 31, so the groove cover 32 does not interfere with the side of the guide post 210. The groove cover 32 provides a relatively sealed fit between the guide post 210 and the limiting block 31, and provides sufficient axial length for the positioning plate 35 to abut against the side of the folding plate 22. The positioning plate 35, through the fit between the positioning post 36 and the positioning hole 227, can prevent the central shaft 23 and the circumferential limiting member 3 from rotating freely. At the same time, the groove cover 32 and the end cover 34 form a clamping surface for the spring 33, so that when the positioning mechanism 2 performs its positioning function, the limiting block 31 always brakes the guide post 210, preventing the positioning shaft 27 from automatically folding.

[0020] To facilitate the release of the braking effect of the limiting block 31 on the guide post 210, this utility model is provided with a pull ring on the positioning plate 35. By axially moving the pull ring, the actual mating depth between the groove cover 32 and the mounting groove 224 can be changed, and the spring 33 will simultaneously generate a compression action. After the guide post 210 leaves the comma-shaped limiting area of ​​the limiting block 31, releasing the pull ring will allow the spring 33 to push the groove cover 32 back to its original position.

[0021] To improve the folding performance of the folding plate 22, the folding plate 22 provided by this utility model has an ear post 225 on the side opposite to the connecting ear 222. The ear post 225, the plate body 221 and the connecting ear 222 are connected to form a U-shaped structure with both ends raised. The center of the ear post 225 is provided with a countersunk hole 226 for installing bolts 212. The side of the mounting base 21 is provided with a brake latch 211. The brake latch 211 is horizontally inserted through the mounting base 21 and is movably engaged. One end of the brake latch 211 is used to brake the folding plate 22 to prevent the folding plate 22 from rotating freely. The trunnion 225 provides a node for mounting bolts 212, giving the folding plate 22 an effective center of rotation. On the other hand, the raised structure formed by the trunnion 225 can make face-to-face contact with the part of the brake latch 211 that extends from the mounting base 21, especially blocking the root of the plate 221, thereby ensuring the stability of the folding plate 22 after it is fully unfolded and preventing the folding plate 22 and the positioning shaft 27 from automatically flipping to the ground position.

[0022] Furthermore, the brake latch 211 provided by this utility model includes a rod portion 2112 and a head portion 2111. A stop portion 2113 radially connected to the side of the head portion 2111 is provided, and a U-shaped opening that mates with the stop portion 2113 is provided on the mounting base 21. By manually pushing the stop portion 2113, the brake latch 211 can move axially along its mating hole with the mounting base 21, thereby facilitating the manual and quick braking and releasing of the folding plate 22. The U-shaped opening provides a constraint on the rotation of the stop portion 2113 and provides axial movement allowance for the head portion 2111, allowing the brake latch 211 to extend a sufficient length toward the folding plate 22 to achieve braking.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
