Description

Technical Field

[0001] This utility model relates to the field of optical cable laying technology, and in particular to an auxiliary structure for optical cable laying. Background Technology

[0002] In the field of telecommunications engineering, the laying of optical cables is a crucial task, as its quality and efficiency directly affect the stability and construction progress of communication networks. With the rapid development of communication technology, the requirements for optical cable laying are becoming increasingly stringent, necessitating not only ensuring the accuracy of cable laying but also improving laying efficiency and reducing labor intensity.

[0003] In traditional fiber optic cable laying, the cable is typically laid manually by rotating the cable reel. This method has several drawbacks: firstly, the speed at which the cable reel is rotated manually is difficult to control precisely, which can easily lead to uneven cable laying speed and affect the quality of the laying; secondly, manual operation is labor-intensive and inefficient, especially when faced with a large number of fiber optic cable laying tasks, making it difficult to meet project schedule requirements.

[0004] In addition, some fiber optic cable laying is done by electric drive, and it is inconvenient to replace the cable reel after the fiber optic cable laying is completed.

[0005] In view of the drawbacks of the existing technology, this application proposes an auxiliary structure for optical cable laying. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides an auxiliary structure for optical cable laying.

[0007] An embodiment of this utility model provides an auxiliary structure for optical cable laying, comprising:

[0008] Frame;

[0009] Auxiliary structure; the auxiliary structure includes a fixed turntable rotatably mounted on a frame, a fixed nut mounted on the frame, an adjusting screw threaded onto the fixed nut, a locking nut threaded onto the adjusting screw to lock the adjusting screw, a mounting plate fixed on the adjusting screw, a rotating disk rotatably mounted on the mounting plate, a rotating turntable fixed on the rotating disk, and conical blocks coaxially fixedly connected to both the rotating turntable and the fixed turntable. A cable winding drum is clamped between the two conical blocks. By adjusting the adjusting screw, the conical blocks can clamp or unlock the cable winding drum.

[0010] Furthermore, a motor is installed on the frame, a first sprocket is fixed to the output end of the motor, and a second sprocket is coaxially fixed on the fixed turntable. The first sprocket and the second sprocket are connected by a chain.

[0011] Furthermore, an adjustment handle is fixed on the adjustment screw, and the adjustment handle is provided with anti-slip texture.

[0012] Furthermore, a clamping sleeve is fixed to the frame, and the clamping sleeve is fixed to the frame by screws, with the fixing nut located inside the clamping sleeve.

[0013] Furthermore, it also includes a support mechanism, which includes a support roller rotatably mounted on the frame. The support roller is located below the rotating turntable and the fixed turntable and abuts against the rotating turntable and the fixed turntable.

[0014] Furthermore, it also includes a tensioning mechanism, which includes a drive screw threadedly connected to the frame, a wheel frame rotatably connected to the drive screw, an adjusting sprocket mounted on the wheel frame, the adjusting sprocket meshing with the chain, and a positioning nut threadedly connected to the drive screw.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Improved deployment efficiency and quality: A motor drives a fixed turntable to rotate, which in turn drives the cable reel and the rotating turntable to rotate synchronously, achieving automated fiber optic cable deployment. Compared to traditional manual deployment methods, this significantly increases deployment speed and ensures more uniform and neat cable laying, effectively improving deployment quality.

[0017] 2. The support roller in the support mechanism is located directly below the rotating turntable and the fixed turntable, and is in close contact with their bottoms, providing additional support for the turntable. It shares the pressure exerted on it by the cable winding drum and optical cable, effectively preventing the turntable from deforming or shifting due to uneven force, and further ensuring the stable rotation of the turntable, thereby ensuring the stability of optical cable laying.

[0018] 3. Achieve stable clamping and convenient replacement of cable reels: By adjusting the adjusting screw, the conical blocks on the rotating and fixed turntables can be brought closer together or separated, thereby clamping or unlocking the cable reel. The special design of the conical blocks automatically aligns the center of the cable reel with the central axis of the turntable, ensuring clamping stability.

[0019] 4. The double-nut locking mechanism of the locking nut effectively prevents the adjusting screw from loosening due to external forces during operation, further ensuring the stability of the cable reel during the laying process.

[0020] 5. The drive screw, wheel frame, and adjusting sprocket in the tensioning mechanism work together to easily adjust the chain tension. When the chain becomes loose or too tight, rotating the drive screw adjusts the position of the adjusting sprocket, ensuring the chain maintains proper tension and preventing problems such as tooth skipping or chain slippage caused by looseness, thus ensuring stable operation of the transmission system. The double-nut structure of the positioning nut effectively locks the adjusted drive screw position, preventing it from loosening due to vibration or other reasons, further guaranteeing the reliability of the tensioning mechanism.

[0021] This invention allows the rotating turntable and the conical block on the fixed turntable to move closer or separate by adjusting the adjusting screw, thereby clamping or unlocking the cable winding drum. This facilitates the replacement of the optical cable winding drum, is simple and convenient to operate, and improves the efficiency of optical cable laying. Attached Figure Description

Detailed Implementation

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0030] like Figures 1-6As shown in the figure, this utility model embodiment proposes an auxiliary structure for optical cable laying, including:

[0031] Frame 1;

[0032] Auxiliary structure: The auxiliary structure includes a fixed turntable 3 rotatably mounted on the frame 1. A short shaft is fixed on the fixed turntable 3. The short shaft is made of high-quality alloy steel and its surface has been precision machined. A bearing seat is installed on the frame 1, and a bearing is installed on the bearing seat. The short shaft and the bearing are interference-fitted, thus ensuring smooth rotation of the fixed turntable 3 and low frictional resistance. A motor 7 is installed on the frame 1. A first sprocket 16 is fixed to the output end of the motor 7. A second sprocket 15 is coaxially fixed on the fixed turntable 3. The first sprocket 16 and the second sprocket 15 are connected by a chain 5. A protective cover is installed on the outside of the chain 5. The protective cover is made of lightweight plastic material, which can prevent external debris from entering the chain drive system and affecting its normal operation, and can also prevent operators from accidentally contacting the chain 5 during operation, ensuring operational safety.

[0033] A fixing nut 8 is installed on the frame 1, and a clamping sleeve 13 is fixed on the frame 1. The clamping sleeve 13 is fixed to the frame 1 by screws, and the fixing nut 8 is located inside the clamping sleeve 13, thus fixing the fixing nut 8. The clamping sleeve 13 can be removed by removing the screws, and the fixing nut 8 can be replaced.

[0034] The adjusting screw 12 is internally threaded onto the fixing nut 8. A locking nut 14 is threaded onto the adjusting screw 12 to lock it in place. An adjusting handle 9 is fixed to the adjusting screw 12. The adjusting handle 9 has anti-slip texture. Rotating the adjusting handle 9 can rotate the adjusting screw 12, thus adjusting its position. Then, rotating the locking nut 14 will cause it to abut against the fixing nut 8, thereby locking the adjusting screw 12. There can be two locking nuts 14, located on both sides of the fixing nut 8. This double fixing nut locking method can effectively prevent the adjusting screw 12 from loosening due to external forces during operation, ensuring the stability of the adjusting screw 12's position.

[0035] An adjustment screw 12 is fixed with a mounting plate 11, and a rotating plate 10 is rotatably mounted on the mounting plate 11. The rotating plate 10 and the mounting plate 11 are connected by a bearing to ensure that the rotating plate 10 can rotate flexibly.

[0036] A rotating turntable 2 is fixed on the rotating disk 10. Conical blocks 4 are coaxially fixedly connected to both the rotating turntable 2 and the fixed turntable 3. A cable winding drum is clamped between the two conical blocks 4. By adjusting the adjusting screw 12, the conical blocks 4 can clamp or unlock the cable winding drum. When the adjusting screw 12 is adjusted to bring the two conical blocks 4 closer together, the center of the cable winding drum can be automatically aligned with the central axis of the fixed turntable 3 and the rotating turntable 2, and it can be stably clamped. When it is necessary to unlock the clamp, the two conical blocks 4 can be separated by adjusting the adjusting screw 12 in the opposite direction, making it convenient to remove or replace the cable winding drum.

[0037] When using this optical cable laying auxiliary structure, first place the cable reel between the fixed turntable 3 and the rotating turntable 2. Then, rotate the adjusting handle 9 to drive the adjusting screw 12 to rotate, causing the rotating turntable 2 to gradually approach the fixed turntable 3. The two conical blocks 4 work together to clamp the cable reel. After clamping, rotate the two locking nuts 14 to make them tightly contact the two sides of the fixed nut 8, thereby locking the position of the adjusting screw 12 and ensuring that the cable reel will not loosen during the laying process. Start the motor 7. The motor 7 drives the fixed turntable 3 to rotate through the transmission system consisting of the first sprocket 16, the second sprocket 15, and the chain 5, which in turn drives the cable reel and the rotating turntable 2 to rotate synchronously, realizing the optical cable laying operation. When it is necessary to replace the cable reel, simply reverse the above steps.

[0038] Example 1

[0039] To ensure stable rotation of the rotating turntable 2 and the fixed turntable 3, and to provide stable support for the cable winding drum, the optical cable laying auxiliary structure also includes a support mechanism. The support mechanism mainly consists of support rollers 6 rotatably mounted on the frame 1. The support rollers 6 are made of high-strength, wear-resistant alloy steel, and their surface undergoes a special hardening treatment to improve their wear resistance and fatigue resistance, extending their service life. Both ends of the support rollers 6 are mounted on the frame 1 via high-precision rolling bearings, ensuring flexible and smooth rotation, reducing frictional resistance, and lowering energy loss.

[0040] The support roller 6 is located directly below the rotating turntable 2 and the fixed turntable 3, and is in close contact with the bottom of the rotating turntable 2 and the fixed turntable 3. During the rotation of the rotating turntable 2 and the fixed turntable 3, the support roller 6 can provide additional support force, share the pressure generated by the cable winding drum and the optical cable, effectively prevent the turntable from deforming or shifting due to uneven force, thereby ensuring the stable rotation of the rotating turntable 2 and the fixed turntable 3, and thus ensuring the stability of cable laying.

[0041] Example 2

[0042] To ensure that the chain 5 maintains appropriate tension during transmission and to prevent problems such as tooth skipping and chain slippage due to loosening, which would affect the normal operation of the optical cable laying auxiliary structure, the device also includes a tensioning mechanism.

[0043] The tensioning mechanism mainly includes a drive screw 19 threaded onto the frame 1. The drive screw 19 is made of high-strength carbon steel and has a galvanized surface, providing excellent corrosion resistance. One end of the drive screw 19 has a convenient hexagonal head, allowing operators to easily rotate it using tools such as wrenches.

[0044] A wheel frame 18 is rotatably connected to the drive screw 19. A guide rail and a slider can be mounted on the frame 1. The slider is fixed to the wheel frame 18 to ensure stable movement. The wheel frame 18 is made of cast iron, has a robust structure, and can withstand significant tensile and compressive forces. The wheel frame 18 is connected to the drive screw 19 via a deep groove ball bearing, ensuring that the wheel frame 18 can rotate freely around the drive screw 19 while also moving axially with the drive screw 19.

[0045] An adjusting sprocket 17 is mounted on the wheel frame 18. The specifications of the adjusting sprocket 17 are matched with those of the chain 5, and its teeth are precisely designed and machined to mesh well with the chain 5, reducing noise and wear during transmission. The adjusting sprocket 17 is fixed to the shaft of the wheel frame 18 by a key connection to ensure that it will not loosen during rotation.

[0046] The adjusting sprocket 17 meshes with the chain 5. By rotating the drive screw 19, the wheel frame 18 and the adjusting sprocket 17 can be moved axially along the drive screw 19, thereby adjusting the position of the adjusting sprocket 17 and adjusting the tension of the chain 5. When the chain 5 becomes loose, rotating the drive screw 19 clockwise moves the adjusting sprocket 17 closer to the motor 7, tightening the chain 5. When the chain 5 is too tight, rotating the drive screw 19 counterclockwise moves the adjusting sprocket 17 away from the motor 7, loosening the chain 5.

[0047] To lock the adjusted position of the drive screw 19 and ensure stable tension of the chain 5, a positioning nut 20 is threaded onto the drive screw 19. The positioning nut 20 adopts a double-nut structure, that is, two positioning nuts 20 are used in conjunction with each other. After adjusting the tension of the chain 5, the two positioning nuts 20 are tightened together to make them in close contact with the frame 1, thereby effectively preventing the drive screw 19 from loosening due to vibration or other reasons during operation, and ensuring the reliability of the tensioning mechanism.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
