Description

Technical Field

[0001] This application relates to the field of cable laying production and application technology, and in particular to a cable trench laying device. Background Technology

[0002] In the process of photovoltaic construction in existing sandy areas, it is necessary to use excavators to pull out the cables and place them into the dug trenches. Then, the trenches are filled and compacted manually to complete the cable laying process.

[0003] At present, cable laying and trench filling are relatively independent. Cable laying and trench filling cannot be carried out at the same time, and trench filling needs to be done manually. The overall laying efficiency is low, which increases the workload of workers and the input of labor costs. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a cable trench laying device, which overcomes the shortcomings of the prior art and aims to solve the problems that the current cable laying and trench filling are relatively independent, cable laying and trench filling cannot be carried out at the same time, and trench filling requires manual work, resulting in low overall laying efficiency, increased workload of workers, and increased labor costs.

[0005] To achieve the above objectives, this application provides the following technical solution: a cable trench laying device, comprising two sets of supports, the two sets of supports being installed behind an excavator, a crossbeam being provided between the two sets of supports, a cable fixing mechanism being provided at the bottom center of the crossbeam, a transmission mechanism being rotatably connected to the bottom of one set of supports, a soil scraping mechanism being provided on the side of the transmission mechanism near the two sets of supports, a driving mechanism being provided on the side of the transmission mechanism away from the soil scraping mechanism, the two ends of the driving mechanism being respectively hinged to one end of the support and one end of the transmission mechanism, a protective mechanism being installed on one side of the support, the protective mechanism being located outside the driving mechanism.

[0006] By adopting the above technical solution, firstly, two sets of brackets are installed on the outside of the excavator. Then, the cable fixing mechanism is set to fix one end of the cable. As the excavator moves forward at the top of the cable trench, it drags the cable along, and the cable enters the inside of the cable trench. When the cable moves forward, the drive mechanism pushes the transmission mechanism. Because the transmission mechanism and the bracket are rotatably connected, the transmission mechanism forms an angle with the bracket under the drive mechanism. When following the excavator forward, the soil scraping mechanism, which is inclined relative to the transmission mechanism, can push the sand back into the cable trench, thus filling the trench. In this way, there is no need for workers to manually fill the cable trench, which effectively improves the efficiency of laying and filling, increases work efficiency, and reduces working time.

[0007] As a preferred technical solution of this application, the wire fixing mechanism includes a fixed half-ring and a movable half-ring. The fixed half-ring is fixedly connected to the bottom of the crossbeam. Fixed plates are provided on both sides of the fixed half-ring, and movable blocks are provided on both sides of the movable half-ring. Adjusting screws are provided on both sides of the movable half-ring. Adjusting screws are rotatably connected inside both sets of fixed plates, and both sets of adjusting screws are threaded through both sets of movable blocks.

[0008] By adopting the above technical solution and setting up a cable fixing mechanism, the moving half-ring can be gradually moved closer to the fixed half-ring by adjusting two sets of adjusting screws during use. The moving half-ring and the fixed half-ring move closer to each other to clamp and fix the cable. This can be done according to the different diameters of the cable, making it more convenient to use and more adaptable to cables of different diameters, thus improving the practicality of the device.

[0009] As a preferred technical solution of this application, the transmission mechanism includes a scraper rod, one end of which is provided with a rotating shaft, the scraper rod is rotatably connected to the support through the rotating shaft, and a fixing block is installed on one side of the scraper rod and threadedly connected to one end of the drive mechanism.

[0010] By adopting the above technical solution and setting a transmission mechanism, the scraper arm will be rotatably connected to the support through the rotating shaft during use. The fixed block on one side can be hinged to one end of the drive mechanism. The one end of the drive mechanism forms a lever effect with the fixed block and the scraper arm, which can better change the angle.

[0011] As a preferred technical solution of this application, the driving mechanism includes a hydraulic rod, one end of which is hinged to the fixed block, and the other end of which is hinged to a connecting block, which is fixedly connected to the bracket.

[0012] By adopting the above technical solution and setting up a drive mechanism, the two ends of the hydraulic rod are hinged to the connecting block and the fixing block respectively during use, ensuring better adjustment of the angle of the scraper rod and improving practicality.

[0013] As a preferred technical solution of this application, the two sets of brackets include longitudinal rods, and each set of longitudinal rods is provided with a vertical rod at the top. Multiple sets of threaded holes are opened at one end of the longitudinal rod and inside the vertical rod.

[0014] By adopting the above technical solution and setting longitudinal bars, multiple sets of threaded holes on the outside of the upright and one end of the longitudinal bars can be connected to the tail of the excavator with bolts during use. This allows for quick installation and deployment, easy replacement and maintenance, and improves the practicality of the device.

[0015] As a preferred technical solution of this application, the scraping mechanism includes a scraper, a T-shaped plate is installed on the side of the scraper near the transmission mechanism, a T-shaped groove is opened inside the transmission mechanism, the T-shaped plate is slidably connected to the inside of the T-shaped groove, and multiple sets of fixing bolts with threads passing through the scraper rod and extending into the T-shaped groove are provided on the outside of the scraper rod, one end of the fixing bolt is threadedly connected to the T-shaped plate.

[0016] By adopting the above technical solution and setting a scraper, the T-shaped plate can slide inside the T-shaped groove during use, while the multiple sets of fixing bolts on the outside can complete the quick connection, making subsequent installation and disassembly more convenient and improving the practicality of the device.

[0017] As a preferred technical solution of this application, the protective mechanism includes a protective box, a through slot is provided on the side of the protective box near the output end of the hydraulic rod, and a top cover is installed on the top of the protective box.

[0018] By adopting the above technical solution and setting up a protective box, the drive mechanism can be effectively protected during use, preventing external soil from affecting the normal operation of the drive mechanism and improving the practicality of the device.

[0019] As a preferred technical solution of this application, multiple sets of reinforcing rods are installed between the two sets of brackets, and the multiple sets of reinforcing rods are all located between the crossbeam and the scraping mechanism.

[0020] By adopting the above technical solution and setting up reinforcing rods, the structural strength between the two sets of supports can be further improved during use, thereby enhancing the overall load-bearing capacity.

[0021] The beneficial effects of this application are: 1. First, two sets of brackets are installed on the outside of the excavator. Then, the cable fixing mechanism secures one end of the cable. As the excavator moves forward at the top of the cable trench, it drags the cable along, allowing it to enter the trench. As the cable advances, a drive mechanism propels the transmission mechanism. Because the transmission mechanism and the brackets are rotatably connected, the transmission mechanism forms an angle with the brackets under the drive mechanism. As the excavator moves forward, a scraping mechanism, which is inclined relative to the transmission mechanism, pushes sand back into the cable trench, filling it. This eliminates the need for manual backfilling of the cable trench, effectively improving laying and backfilling efficiency, increasing work efficiency, and reducing working time.

[0022] 2. By setting up a cable fixing mechanism, during use, the moving half-ring can be gradually moved closer to the fixed half-ring by adjusting two sets of adjusting screws. The moving half-ring and the fixed half-ring move closer to each other to clamp and fix the cable. It can fix the cable according to different diameters, making it more convenient to use and more adaptable to cables of different diameters, thus improving the practicality of the device.

A soil scraping mechanism 5 is provided on the side of the transmission mechanism 4 near the two sets of supports 1, and a drive mechanism 6 is provided on the side of the transmission mechanism 4 away from the soil scraping mechanism 5. The two ends of the drive mechanism 6 are respectively hinged to one end of the support 1 and one end of the transmission mechanism 4. A protective mechanism 7 is installed on one side of the support 1, and the protective mechanism 7 is located outside the drive mechanism 6. The transmission mechanism 4 includes a soil scraping rod 401, one end of which is provided with a rotating shaft 405.

A fixing block 402 is installed on one side of the soil scraping rod 401 and threadedly connected to one end of the drive mechanism 6.

[0027] First, two sets of brackets 1 are installed on the outside of the excavator. Then, the cable fixing mechanism 3 secures one end of the cable. As the excavator moves forward along the top of the cable trench, it drags the cable, which then enters the trench. As the cable advances, the drive mechanism 6 pushes the transmission mechanism 4. Because the transmission mechanism 4 is rotatably connected to the brackets 1, it forms an angle with the brackets 1 under the drive of the drive mechanism 6. The scraper, which is tilted relative to the transmission mechanism 4, moves forward with the excavator. Structure 5 can push sand back into the cable trench to fill the trench, thus eliminating the need for manual backfilling of the cable trench during use, effectively improving the efficiency of laying and backfilling, increasing work efficiency, and reducing working time; by setting up transmission mechanism 4, during use, the scraper rod 401 will be rotatably connected to the support 1 through the rotating shaft 405, and the fixed block 402 on one side can be hinged to one end of the drive mechanism 6. One end of the drive mechanism 6, the fixed block 402 and the scraper rod 401 form a lever effect, which can better change the angle.

Fixed plates 303 are provided on both sides of the fixed half-ring 301. Movable blocks 304 are provided on both sides of the movable half-ring 302. Adjusting screws 305 are provided on both sides of the movable half-ring 302. Adjusting screws 305 are rotatably connected inside both sets of fixed plates 303. Both sets of adjusting screws 305 are threaded through both sets of movable blocks 304. The drive mechanism 6 includes a hydraulic rod 601. One end of the hydraulic rod 601 is hinged to the fixed block 402, and the other end of the hydraulic rod 601 is hinged to the connecting block 602. The connecting block 602 is fixedly connected to the bracket 1. The scraping mechanism 5 includes a scraper 501. A T-shaped plate 502 is installed on the side of the scraper 501 near the transmission mechanism 4. A T-shaped groove 403 is opened inside the transmission mechanism 4. The T-shaped plate 502 is slidably connected inside the T-shaped groove 403. Multiple sets of threads are provided on the outside of the scraper rod 401, extending through the scraper rod 401 and into the T-shaped groove. The fixing bolt 406 inside 403 is threadedly connected at one end to the T-shaped plate 502. By setting up the cable fixing mechanism 3, during use, the moving half-ring 302 can be gradually moved closer to the fixed half-ring 301 by adjusting two sets of adjusting screws 305. The moving half-ring 302 and the fixed half-ring 301 move closer to each other to clamp and fix the cable, allowing for fixing according to different cable diameters. This makes it more convenient to use and provides better adaptability to cables of different diameters, improving the practicality of the device. By setting up the drive mechanism 6, during use, the two ends of the hydraulic rod 601 are hinged to the connecting block 602 and the fixing block 402 respectively, ensuring better adjustment of the angle of the scraper rod 401 and improving practicality. By setting up the scraper 501, during use, the T-shaped plate 502 can slide inside the T-shaped groove 403, while the multiple sets of fixing bolts 406 on the outside can complete a quick connection, making subsequent installation and disassembly more convenient and improving the practicality of the device.

[0029] Reference Figure 1-5The two sets of supports 1 include longitudinal rods 101, and each set of longitudinal rods 101 is equipped with a vertical rod 102 at its top. Multiple sets of threaded holes 103 are formed at one end of the longitudinal rods 101 and inside the vertical rods 102. By setting the longitudinal rods 101, during use, the external side of the vertical rods 102 and the multiple sets of threaded holes 103 at one end of the longitudinal rods 101 can be connected to the tail of the excavator via bolts, enabling quick installation and deployment, facilitating replacement and maintenance, and improving the practicality of the device. The protective mechanism 7 includes a protective box 701, which is located near the hydraulic rod. A through slot 703 is provided on one side of the output end of 601, and a top cover 702 is installed on the top of the protective box 701. By setting the protective box 701, the drive mechanism 6 can be effectively protected during use, preventing external soil from affecting the normal operation of the drive mechanism 6 and improving the practicality of the device. Multiple sets of reinforcing rods 8 are installed between the two sets of brackets 1, and the multiple sets of reinforcing rods 8 are all located between the crossbeam 2 and the soil scraping mechanism 5. By setting the reinforcing rods 8, the structural strength between the two sets of brackets 1 can be further improved during use, and the overall load-bearing performance can be improved.

[0030] Working principle: First, two sets of brackets 1 are installed on the outside of the excavator. Then, the cable fixing mechanism 3 fixes one end of the cable. As the excavator moves forward at the top of the cable trench, it drags the cable along, allowing it to enter the trench. As the cable advances, the drive mechanism 6 pushes the transmission mechanism 4. Because the transmission mechanism 4 is rotatably connected to the brackets 1, it forms an angle with the brackets 1 under the drive of the drive mechanism 6. While following the excavator's advance, the soil scraping mechanism 5, which is inclined relative to the transmission mechanism 4, pushes sand back onto the cable. The trench is filled with soil, eliminating the need for manual filling of the cable trench during use. This effectively improves the efficiency of laying and filling, increases work efficiency, and reduces working time. By setting up the cable fixing mechanism 3, the moving half ring 302 can be gradually moved closer to the fixed half ring 301 by adjusting two sets of adjusting screws 305. The moving half ring 302 and the fixed half ring 301 move closer to each other to clamp and fix the cable. It can fix the cable according to different diameters, making it more convenient to use and more adaptable to cables of different diameters, thus improving the practicality of the device. In this design, by setting up a transmission mechanism 4, the scraper arm 401 is rotatably connected to the support 1 via a rotating shaft 405 during use. The fixed block 402 on one side can be hinged to one end of the drive mechanism 6. A lever effect is formed between one end of the drive mechanism 6, the fixed block 402, and the scraper arm 401, allowing for better angle changes. By setting up the drive mechanism 6, during use, the two ends of the hydraulic rod 601 are hinged to the connecting block 602 and the fixed block 402 respectively, ensuring better adjustment of the angle of the scraper arm 401 and improving practicality. Meanwhile, by setting the longitudinal rod 101, during use, the external part of the upright rod 102 and one end of the longitudinal rod 101, multiple sets of threaded holes 103 can be connected to the tail of the excavator with bolts, which can quickly complete the installation and deployment, and facilitate replacement and maintenance, thus improving the practicality of the device. In addition, by setting the scraper 501, the T-shaped plate 502 can slide inside the T-shaped groove 403 during use, and the multiple sets of fixing bolts 406 set on the outside can complete the quick connection, making subsequent installation and disassembly more convenient and improving the practicality of the device; by setting the protective box 701, the drive mechanism 6 can be effectively protected during use, preventing external soil from affecting the normal operation of the drive mechanism 6, thus improving the practicality of the device; by setting the reinforcing rod 8, the structural strength between the two sets of brackets 1 can be further improved during use, enhancing the overall load-bearing performance.
