Description

Technical Field

[0001] This utility model relates to the field of pipeline laying technology, and in particular to a buried wire device for civil engineering construction. Background Technology

[0002] In civil engineering construction, pipeline laying is an extremely important and common task. Traditional buried wiring methods present many challenging problems, which greatly restrict construction efficiency and project quality.

[0003] In the early stages of construction, the lack of stable and standardized support structures for the placement of the pipeline reel caused frequent shaking and displacement during the cable laying process. This not only interfered with the normal release of the pipeline but also easily led to tangling and knotting, severely impacting the construction progress. Furthermore, after the pipeline was led out of the reel, it lacked an effective guiding path and often rubbed and scraped against surrounding debris, causing wear and tear on the pipeline surface and creating safety hazards.

[0004] During the cable laying process, construction workers often struggle to precisely adjust the cable laying device based on varying trench depths, relying instead on experience for rough adjustments. This results in significant deviations in the cable's placement, preventing it from accurately landing at the bottom of the trench and impacting its subsequent performance. Furthermore, the lack of a coordinated power system means that workers must simultaneously pull the cable and push the equipment, leading to high labor intensity, extremely low efficiency, and difficulty in controlling the laying speed. This can result in cables becoming either loose or too tight, compromising the quality of the installation. Utility Model Content

[0024] Combination Figures 1 to 5 As shown, this utility model discloses a wire laying device for civil construction, including a wire laying frame 1 and a pipeline reel 2. The pipeline reel 2 is provided at the rear end of the top of the wire laying frame 1, and the pipeline reel 2 is provided on both sides of the pipeline reel 2. The support 21 is fixed to both sides of the rear end of the top of the wire laying frame 1. A drive motor 22 is installed on the side wall of one of the support 21. The rotating shaft of the drive motor 22 is fixedly connected to the rotating shaft on one side of the pipeline reel 2. A housing 3 is fixed at the front end of the top of the wire laying frame 1. A wire laying assembly is provided inside the housing 3. A scraper 5 is installed at the rear end of the wire laying frame 1.

[0025] The cable laying assembly includes a support cylinder 4 fixed inside the front and rear ends of the housing 3. A top frame 41 is fixed to the top of the support cylinder 4. A telescopic rod 42 is installed on the top of the top frame 41. The output end of the bottom of the telescopic rod 42 extends into the top frame 41 and is fixed with a movable column 43. The movable column 43 is placed inside the support cylinder 4 and can slide up and down therein. A cable laying head 44 is provided at the bottom of the support cylinder 4.

[0026] The movable column 43 has a retraction groove 431 inside, and a movable connecting rod 432 is installed inside the retraction groove 431. The bottom end of the movable connecting rod 432 protrudes from the bottom of the support cylinder 4 and is fixedly connected to the top of the laying head 44. A buffer spring 433 is fixedly installed on the top of the movable connecting rod 432, and the top of the buffer spring 433 is fixedly connected to the inner top wall of the retraction groove 431.

[0027] The lay-up head 44 has an internal cavity 444. Guide wheels 445 are rotatably mounted on the upper and lower ends of the internal cavity 444. A side frame 442 is fixed to the side wall of the lay-up head 44. Gears 441 are rotatably mounted on the upper and lower ends of the side frame 442. A gear 441 is correspondingly mounted on one side of each guide wheel 445 and is connected to the shaft on one side of the guide wheel 445 and the shaft on one side of the gear 441. A servo motor 443 is mounted on the upper end of one side of the side frame 442. The shaft of the servo motor 443 is fixedly connected to the shaft on one side of the gear 441. A roller 446 is rotatably mounted on the bottom of the lay-up head 44.

[0028] A wire groove 11 is provided between the pipeline tray 2 and the housing 3. The wire groove 11 is located in the middle of the inside of the buried wire frame 1. A through groove 12 is provided directly below the support cylinder 4. The through groove 12 is located at the front end of the inside of the buried wire frame 1.

[0029] Specifically, the workers place the cable reel 2, which is wound around the cable, between the supports 21. The supports 21 can support the weight of the cable reel 2 and the cable. After installation, one end of the cable is introduced into the wire guide 11. The wire guide 11 has a smooth groove design and is specially treated inside to reduce friction between the cable and the groove wall, ensuring that the cable can smoothly extend under the cable laying vehicle frame 1, preparing for the subsequent laying process.

[0030] Depending on the specific project requirements, the depth of the excavated trench varies. Therefore, the position of the cable laying head 44 needs adjustment. Based on measurement data, the construction workers operate the telescopic rod 42. Under the action of the telescopic rod 42, the movable column 43 is lowered, thus pushing the cable laying head 44 down through the pre-set through-slot 12 on the cable laying vehicle frame 1 until the rotating roller 446 at the bottom of the cable laying head 44 precisely contacts the bottom of the trench. During this process, the construction workers continuously make fine adjustments, using visual observation and auxiliary leveling instruments to ensure that the rotating roller 446 is in optimal contact with the bottom of the trench, so that the pipeline can be accurately laid to the bottom of the trench subsequently.

[0031] Once preparations are complete, the pipeline laying process begins. Workers slowly guide the pipeline, already passed through the conductor trough 11 and drawn from the pipeline reel 2, into the internal cavity 444 of the laying head 44. The guide wheels 445, mounted at the upper and lower ends of the internal cavity 444, have a special anti-slip treatment to effectively increase friction with the pipeline. At this time, one worker pushes the laying cart 1, which is designed with a handle for easy pushing and wheels with good steering performance, allowing for flexible movement on the trough. Simultaneously, the drive motor 22 and servo motor 443 are activated. The drive motor 22 powers the pipeline reel 2 to rotate continuously, achieving uniform pipeline release. The servo motor 443 drives the gear 441 through a series of transmission devices, causing the guide wheels 445 to rotate at high speed in opposite directions. Utilizing the friction between the guide wheels 445 and the pipeline, the pipeline released from the pipeline reel 2 is smoothly pulled, ensuring precise placement of the pipeline into the trough.

[0032] During the process of moving the cable laying vehicle 1 and laying the pipeline, the scraper 5 at the rear end of the cable laying vehicle 1 scrapes the soil into the trench to lay the cable.

[0033] As the cable laying vehicle 1 moves continuously, the cable laying head 44 moves synchronously. Since the bottom of the trough is often uneven, the roller 446 at the bottom of the cable laying head 44 plays a crucial role. Made of high-strength and wear-resistant rubber, the roller 446 cleverly transforms the sliding friction that might occur between the cable laying head 44 and the bottom of the trough into rolling friction. This transformation significantly reduces the coefficient of friction, effectively preventing damage to the bottom of the cable laying head 44 caused by prolonged friction with the trough.

[0034] Furthermore, if the bottom of the trench is particularly uneven, the raised portion of the trench will push the cable laying head 44 upwards. At this time, the movable connecting rod 432 connected to the cable laying head 44 will quickly move upwards within the retraction groove 431, which is pre-installed with a buffer spring 433. During the upward movement of the movable connecting rod 432, the buffer spring 433 will compress the buffer spring 433, which will instantly generate a strong elastic force. This elastic force can effectively buffer the impact of the trench on the cable laying head 44, preventing the cable laying head 44 from being damaged due to long-term contact with the uneven trench, thus ensuring that the entire cable laying operation can be carried out stably and efficiently.
