Description

Technical Field

[0001] The present invention relates to the technical field of communication cable laying equipment, and specifically relates to an auxiliary equipment for communication cable laying. Background Technique

[0002] In the field of communication engineering, cable laying is a key and fundamental task, and its construction quality and efficiency directly affect the overall performance and operation stability of the communication system. With the rapid development of communication technology, the large-scale construction of 5G networks, and the continuous growth of communication service demands, the requirements for cable laying are also increasing day by day. However, there are the following deficiencies in the current cable laying process, as follows: During the cable laying process, manual cable laying not only has a large labor intensity and requires a large amount of manpower input, but also has extremely low construction efficiency in long-distance and complex terrain laying scenarios. For example, in special terrain conditions such as mountains and rivers, it is extremely difficult to manually carry and lay cables, which not only consumes a large amount of time, but also during the process of dragging the cable, the cable contacts the ground, and it is easy to cause cable wear. If some simple auxiliary equipment is used, such as an ordinary cable pay-off rack, its functions are single, and it can only achieve the basic cable pay-off function, and cannot meet the requirements of accurately controlling the cable laying tension and ensuring the accuracy of the cable laying path. Summary of the Invention

[0003] The present invention provides an auxiliary equipment for communication cable laying, which has the advantages of small friction and fast transportation, and solves the problems in the above background technique.

[0004] The present invention provides the following technical solution: An auxiliary equipment for communication cable laying includes two fixed frames and a limit sleeve movably sleeved on the cable. The fixed frames are in a V shape. The rear sides of the two fixed frames are movably installed with rollers through shafts. The middle parts of the fixed frames are movably sleeved with horizontal shafts. The front ends of the horizontal shafts are movably sleeved with support frames. The front sides of the support frames are movably installed with rollers through shafts. A support device is movably sleeved on the horizontal shaft between the fixed frames and the support frames. On the top of the left fixed frame, a support plate I is fixedly installed. On the top of the right fixed frame, a support plate II is fixedly installed. On the upper surfaces of the support plate I and the support plate II, limit sleeves are symmetrically and fixedly installed. At the bottoms of the adjacent sides of the support plate I and the support plate II, positioning disks are fixedly installed through shaft rods. On the upper shaft rods of the positioning disks, connecting rods are movably sleeved to support the cable, avoid the cable contacting the bottom surface, causing wear and damage to the outer surface of the cable, effectively protect the cable, and improve the transportation efficiency.

[0005] Preferably, the support device includes a connecting sleeve which is movably sleeved on the horizontal shaft. Threaded sleeves are movably sleeved on both sides of the top of the horizontal shaft on the connecting sleeve. A worm gear is fixedly sleeved on the outside of the threaded sleeve. A lifting screw rod is threadedly sleeved inside the threaded sleeve. The bottom end of the lifting screw rod is movably sleeved with a bottom plate below the connecting sleeve. Cone nails are uniformly and fixedly installed on the bottom of the bottom plate. A rotating shaft is movably sleeved on the fixed frame and the support frame. A worm is fixedly sleeved on the rotating shaft. The worm is meshed and connected with the worm gear. A rotating handle is fixedly installed at the front end of the rotating shaft and in front of the support frame, lifting the roller, changing the rolling into sliding, and avoiding large displacement at the conveying position, resulting in disorder in the cable conveying.

[0006] Preferably, vertical boxes are movably clamped in the middle of the support plate Ⅰ and the support plate Ⅱ. A driving roller is movably sleeved below the bottom of the vertical box and below the cable. The driving roller is movably sleeved with the lower half of the cable. A moving block is movably clamped inside the vertical box. A tightening screw rod is threadedly sleeved on the top of the vertical box. The bottom end of the tightening screw rod is movably sleeved with the top of the moving block. A clamping roller is movably sleeved on the moving block. The clamping roller is movably sleeved with the upper half of the cable. A driving motor is fixedly connected to the vertical box located on the support plate Ⅰ. The output shaft of the driving motor is fixedly connected to the front end of the driving roller. The cable is clamped by the driving roller and the clamping roller, and a certain driving force is provided to improve the driving force of the cable conveying, reduce the force of manual dragging, and reduce the labor intensity of the laying personnel.

[0007] Preferably, the limiting sleeve includes a bottom ring and a sealing ring. One end of the bottom ring and one end of the sealing ring are movably connected by a shaft. Ball bearings are movably sleeved inside the bottom ring and the sealing ring. The ball bearings are movably connected with the cable. Card holes are symmetrically opened at the other end of the bottom ring. Limiting columns are symmetrically and movably sleeved inside the other end of the sealing ring. A spring is movably installed above the limiting columns inside the sealing ring. The two ends of the spring are respectively fixedly connected with the sealing ring and the limiting column. The bottom end of the limiting column is movably sleeved with the card hole. The cable is wrapped, and the contact with the cable is made through the ball bearings, reducing friction and keeping the cable between the two limiting sleeves straight, so that the driving roller and the clamping roller have a large contact with the cable.

[0008] Preferably, the positioning disk is semicircular. Positioning holes are uniformly opened on the positioning disk. Insertion holes corresponding to the positioning holes are opened on the connecting rod. Positioning screws are threadedly sleeved in the positioning holes. The positioning screws are movably sleeved with the insertion holes. Angle transfer positioning is carried out through the support plate Ⅰ and the support plate Ⅱ, and then the cable is turned during conveying, and continuous conveying and laying at multiple angles can be realized.

[0009] Preferably, a tension sensor is fixedly installed on the first support plate on the right side of the vertical box. The left end of the tension sensor is fixedly connected to the right side of the vertical box. The tension of the cable is detected by the tension sensor to avoid excessive or too small tension of the cable.

[0010] The present invention has the following beneficial effects: 1. Through the settings of the fixing frame and the limiting sleeve, the limiting sleeve and the fixing frame support the cable. When the cable is pulled and unfolded, this device is evenly arranged on the laying route, or multiple devices can be directly installed on the cable. During the pulling process, through the rollers on the fixing frame and the support frame, this device moves forward together with the cable. Only after moving a certain distance, the last device is stopped from moving forward and stays in place to support the cable, ensuring that the cable is kept away from the ground during the laying process and avoiding large friction between the cable and the ground. On the one hand, it reduces the resistance of cable laying and improves the laying efficiency. On the other hand, it reduces the wear of the cable surface caused by friction.

[0011] 2. Through the settings of the driving roller and the clamping roller, the two clamp the cable, and through the drive of the driving motor, the driving roller drives the cable, thereby completing the conveying of the cable, ensuring that the cable can also be automatically conveyed during long-distance laying, reducing the work intensity of the laying personnel and improving the laying efficiency of the cable. Moreover, through the settings of the tension sensor and the vertical box, the tension of the cable on the left side of the first support plate is detected. On the one hand, it avoids too small tension, resulting in the middle part of this section of the cable dragging on the ground and causing wear of the cable during movement. On the other hand, it avoids too large tension, resulting in the cable being overstretched and damaging the internal structure of the cable, affecting the signal transmission quality.

Detailed implementation mode

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0015] Please refer to Figure 1 - Figure 2 , a communication cable laying auxiliary device, including two fixed frames 1 and a limit sleeve 6 movably sleeved on the cable 17. The fixed frame 1 is in a V shape. The rear sides of the two fixed frames 1 are movably installed with rollers through shafts. The middle part of the fixed frame 1 is movably sleeved with a horizontal axis 2. The front end of the horizontal axis 2 is movably sleeved with a support frame 3. The front side of the support frame 3 is movably installed with a roller through a shaft. A support device 4 is movably sleeved on the horizontal axis 2 between the fixed frame 1 and the support frame 3. A support plate I 5 is fixedly installed on the top of the left fixed frame 1, and a support plate II 7 is fixedly installed on the top of the right fixed frame 1. Limit sleeves 6 are symmetrically and fixedly installed on the upper surfaces of the support plate I 5 and the support plate II 7. The bottom of the adjacent sides of the support plate I 5 and the support plate II 7 are fixedly installed with positioning disks 13 through shaft rods. A connecting rod 14 is movably sleeved on the shaft rod of the upper part of the positioning disk 13. When laying the cable 17, the cable 17 is sleeved with the limit sleeve 6, and the cable 17 is supported by the limit sleeve 6 and the fixed frame 1. When the cable 17 is pulled and unfolded, this device is evenly arranged on the laying route, or multiple devices can be directly installed on the cable 17. When pulling, through the rollers on the fixed frame 1 and the support frame 3, this device can move forward together with the cable 17. Only after moving forward a certain distance, stop the last device from moving forward and stop at the original place to support the cable 17, ensuring that the cable 17 is far from the ground during the laying process, avoiding large friction between the cable and the ground surface. On the one hand, it reduces the resistance of cable laying and improves the laying efficiency. On the other hand, it reduces the wear of the cable surface caused by friction; Please refer to Figure 2 - Figure 3, the support device 4 includes a connecting sleeve 41. The connecting sleeve 41 is movably sleeved on the horizontal shaft 2. On both sides of the top of the horizontal shaft 2 on the connecting sleeve 41, there are thread sleeves 42 movably sleeved. A worm gear 43 is fixedly sleeved on the outside of the thread sleeve 42. A lifting screw rod 44 is threadedly sleeved inside the thread sleeve 42. At the bottom end of the lifting screw rod 44 and below the connecting sleeve 41, there is a bottom plate 45 movably sleeved. Conical nails are evenly fixedly installed at the bottom of the bottom plate 45. A rotating shaft 46 is movably sleeved on the fixed frame 1 and the support frame 3. A worm 47 is fixedly sleeved on the rotating shaft 46. The worm 47 is meshed and connected with the worm gear 43. At the front end of the rotating shaft 46 and at the front end of the support frame 3, there is a rotating handle 48 fixedly installed. When the roller carries the limit sleeve 6 to the location for laying the conveying cable 17, by rotating the rotating handle 48, the worm 47 is driven to rotate through the rotating shaft 46, and through the transmission of the worm gear 43, the thread sleeve 42 is driven to rotate, driving the lifting screw rod 44 to descend, so that the bottom plate 45 contacts the ground surface and lifts the roller from the ground, thereby enabling the device to stand upright on the ground and play a supporting role for the cable 17, preventing the roller from moving under the pulling of the cable 17 and being unable to play an effective guiding role for the cable 17; Please refer to Figure 2 - Figure 4 , a vertical box 8 is movably clamped in the middle of both the support plate I 5 and the support plate II 7. A driving roller 9 is movably sleeved at the bottom of the vertical box 8 and below the cable 17. The driving roller 9 is movably sleeved on the lower half of the cable 17. A moving block 10 is movably clamped inside the vertical box 8. A tightening screw rod 11 is threadedly sleeved at the top of the vertical box 8. The bottom end of the tightening screw rod 11 is movably sleeved with the top of the moving block 10. A clamping roller 12 is movably sleeved on the moving block 10. The clamping roller 12 is movably sleeved on the upper half of the cable 17. A driving motor 15 is fixedly connected to the vertical box 8 located on the support plate I 5. The output shaft of the driving motor 15 is fixedly connected to the front end of the driving roller 9. During the process of laying the cable, by rotating the tightening screw rod 11, the moving block 10 and the clamping roller 12 are driven to descend, so that the clamping roller 12 and the driving roller 9 clamp the cable 17, avoiding the cable 17 from detaching from the device during the laying and conveying process. Subsequently, the driving roller 9 is driven to rotate by the driving motor 15, thereby conveying the cable 17. In this way, through the clamping and conveying between the clamping rollers 12 and the driving rollers 9 on multiple groups of auxiliary devices, it is ensured that the cable can also be automatically conveyed during the long-distance laying process, reducing the work intensity of the laying personnel and improving the laying efficiency of the cable; Please refer to Figure 4 - Figure 5, the limit sleeve 6 includes a bottom ring 61 and a sealing ring 62. One end of the bottom ring 61 and one end of the sealing ring 62 are movably connected by a shaft. A ball 63 is movably sleeved inside the bottom ring 61 and the sealing ring 62. The ball 63 is movably connected to the cable 17. The other end of the bottom ring 61 is symmetrically provided with a clamping hole. Inside the other end of the sealing ring 62, a limit post 64 is symmetrically and movably sleeved. Inside the sealing ring 62 and above the limit post 64, a spring 65 is movably installed. The two ends of the spring 65 are respectively fixedly connected to the sealing ring 62 and the limit post 64. The bottom end of the limit post 64 is movably sleeved with the clamping hole. When installing the cable 17 with the limit sleeve 6, first open the sealing ring 62, then place the cable 17 between the balls 63, then align the limit post 64 on the sealing ring 62 with the clamping hole, and under the pressing of the spring 65, the limit post 64 is inserted into the clamping hole, thereby limiting the bottom ring 61 and the sealing ring 62. The cable 17 is supported by the limit sleeve 6, and the ball 63 contacts the cable 17 to further reduce friction, further reduce the wear on the surface of the cable 17, and cooperate with the clamping roller 12 and the driving roller 9 to make the cable 17 between the two limit sleeves 6 on the support plate I 5 keep a straight state, so that the clamping roller 12 and the driving roller 9 can better apply force to the cable 17 and convey the cable 17; Please refer to Figure 6 , the positioning disk 13 is semicircular. The positioning disk 13 is evenly provided with positioning holes 19. The connecting rod 14 is provided with insertion holes corresponding to the positioning holes 19. A positioning screw 18 is threadedly sleeved in the positioning hole 19. The positioning screw 18 is movably sleeved with the insertion hole. When the cable 17 needs to turn during conveyance, the support plate II 7 is driven by the connecting rod 14 to rotate a certain angle. Subsequently, the positioning hole 19 and the insertion hole are limited by the positioning screw 18 to maintain the turning angle of the cable 17 at this time, so that the cable 17 can continue to be conveyed at the place where it needs to turn, further improving the laying efficiency; Please refer to Figure 7 , a tension sensor 16 is fixedly installed on the support plate I 5 and on the right side of the vertical box 8. The left end of the tension sensor 16 is fixedly connected to the right side of the vertical box 8. When the driving roller 9 and the clamping roller 12 clamp the cable 17, the cable 17 on the left side of the support plate I 5 has a certain pulling force on the driving roller 9 and the cable 17. Then, the tension of this section of the cable 17 is detected by the tension sensor 16. On the one hand, it is avoided that the tension is too small, resulting in the middle part of this section of the cable 17 dragging on the ground and causing wear to the cable 17 during movement. On the other hand, it is avoided that the tension is too large, resulting in the cable 17 being overstretched and causing damage to the internal structure of the cable, affecting the signal transmission quality.

[0016] Working principle, Method 1: First, determine the cable laying route, then install this device at a certain distance and place it at the turning points. Subsequently, one end of the cable 17 is passed through the limit sleeves 6 in each device in sequence, and it is clamped by the driving roller 9 and the clamping roller 12; Method 2: Directly install all the devices on the cable 17, and as the cable 17 is pulled, roll through the rollers. After reaching a certain distance, place the rearmost device and support it through the support device 4; In the above process, when installing the cable 17 and the limit sleeve 6, first open the sealing ring 62, then place the cable 17 between the balls 63, then dock the limit posts 64 on the sealing ring 62 with the card holes, and under the pressing of the spring 65, the limit posts 64 are inserted into the card holes, thereby limiting the bottom ring 61 and the sealing ring 62. The cable 17 is supported by the limit sleeve 6, and contacts the cable 17 through the balls 63. Then, by rotating and tightening the screw rod 11, the moving block 10 and the clamping roller 12 are driven to descend, so that the clamping roller 12 and the driving roller 9 clamp the cable 17. When the device reaches the position, by rotating the rotating handle 48, the worm 47 is driven to rotate through the rotating shaft 46, and through the transmission of the worm gear 43, the threaded sleeve 42 is driven to rotate, driving the lifting screw rod 44 to descend, so that the bottom plate 45 contacts the bottom surface and lifts the roller from the ground, so that the device can stand upright on the ground and play a supporting role for the cable 17, preventing the roller from moving under the pulling of the cable 17; Finally, driven by the drive motor 15, the driving roller 9 is driven to rotate, thereby conveying the cable 17.
