Description

Technical Field

[0001] This utility model relates to the field of underground cable technology, specifically to an underground cable laying structure. Background Technology

[0002] Underground cable laying is a core method for urban power and communication transmission, avoiding the problems of overhead lines occupying land and being affected by climate. However, traditional structures have obvious drawbacks. Traditional laying methods mainly include direct burial, trenching, or duct laying. Directly buried cables are susceptible to soil corrosion and external damage, and maintenance requires excavating the road surface; trench laying is costly and occupies a large amount of underground space; duct laying has problems such as poor heat dissipation and difficulty in cable pulling.

[0003] Based on the above, the applicant believes the following deficiencies exist:

[0004] The existing device suffers from poor versatility, high replacement costs, insufficient installation stability, and low operating efficiency. It cannot adjust the support frame spacing, can only adapt to cable winding cylinders of a single length, and is completely incompatible with cylinders of different lengths. Furthermore, due to its poor adaptability, the existing device requires frequent replacement of parts when dealing with cylinders of different specifications, which increases economic costs. Utility Model Content

[0005] The purpose of this utility model is to provide an underground cable laying structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an underground cable laying structure, including a main frame, an auxiliary ramp fixedly connected to the left side of the main frame, an adjustable cable winding cylinder placement mechanism provided on the surface of the main frame, a cable leveling adjustment mechanism provided on the right side of the main frame, and a cable winding cylinder provided on the top of the main frame;

[0007] The adjustable cable winding cylinder placement mechanism includes an adjustment groove, which is located at the front and rear ends of the top of the main frame. A first fixed seat is fixedly connected to the left side of the front and rear ends of the bottom of the main frame. A bidirectional screw is rotatably connected to the inner end of the first fixed seat. A servo motor is mounted on the front of the first fixed seat. A second fixed seat is fixedly connected to the right side of the front and rear ends of the bottom of the main frame. A guide rod is fixedly connected to the inner end of the second fixed seat. A connecting slide is provided on the surface of the bidirectional screw and the guide rod. A support frame is fixedly connected to the top of the connecting slide. Built-in slide rods are fixedly connected to the left and right sides of the inner end of the support frame. A sliding seat is provided on the surface of the sliding rod, and a connecting plate is fixedly connected to the inner end of the sliding seat. A first controller is installed at the top center of the support frame, and a first electrically controlled telescopic column is installed at the bottom of the first controller. A second controller is installed at the outer center of the connecting plate, and a second electrically controlled telescopic column is installed at the inner end of the second controller. A magnetic connecting seat is installed on the surface of the second electrically controlled telescopic column. Auxiliary limiting seats are fixedly connected to the left and right sides of the bottom of the inner end of the built-in sliding rod. A bidirectional screw is driven to rotate by a servo motor, which drives the threaded connecting sliding seat to slide laterally along the guide rod, thereby adjusting the distance between the front and rear sets of support frames. This design is adaptable to cable winding cylinders of different lengths, eliminating the need for custom-made brackets for specific cylinder specifications and reducing equipment replacement costs. The first controller controls the extension and retraction of the first electrically controlled telescopic column, which moves the connecting plate and sliding seat longitudinally along the built-in slide rod. The height of the second electrically controlled telescopic column and the magnetic connector can be adjusted to accommodate cable winding cylinders of different diameters, avoiding installation instability caused by differences in cylinder diameter. The second controller controls the extension and retraction of the second electrically controlled telescopic column, which, together with the magnetic connector, is inserted into the center of the cable winding cylinder. This allows for quick and easy magnetic fixation of the cylinder, and the tightening force can be adjusted to prevent the cylinder from shaking or shifting during installation. The adjustable groove allows for the adaptation to different specifications of cable winding cylinders, making it highly versatile, reducing operational difficulty, and improving installation efficiency.

[0008] Preferably, the bidirectional screw is fixedly connected to the output end on the back of the servo motor, the left side of the connecting slide is threadedly connected to the surface of the bidirectional screw, and the right side of the connecting slide is slidably connected to the surface of the guide rod.

[0009] Preferably, the sliding seat is slidably connected to the surface of the built-in sliding rod, the bottom end of the first electrically controlled telescopic column is installed at the top center of the connecting plate, and the magnetic connecting seat is installed at the end of the second electrically controlled telescopic column away from the connecting plate.

[0010] Preferably, the cable leveling adjustment mechanism includes a first extension plate, which is fixedly connected to the bottom of the right rear end of the main frame. A second extension plate is fixedly connected to the bottom of the right front end of the main frame. A first frame is fixedly connected to the top of the first extension plate, and a second frame is fixedly connected to the top of the second extension plate. A screw is rotatably connected to the center of the inner end of the first frame. A servo control motor is installed at the center of the top of the first frame. A fixing rod is fixedly connected to the center of the inner end of the second frame. A connecting seat is provided on the surface of both the screw and the fixing rod. A leveling and cleaning auxiliary guide roller is installed at the inner end of the connecting seat. The servo control motor drives the screw to rotate, causing the threaded connecting seat to slide laterally along the fixing rod, thereby adjusting the lateral position of the leveling and cleaning auxiliary guide roller. When cables are released from the cable winding cylinder and laid underground, the roller can adapt to the cable release trajectory by moving laterally, preventing the cables from stacking or becoming skewed due to trajectory deviation. This ensures that the cables are neatly arranged after laying, reducing the difficulty of sorting them during later maintenance. The flat cleaning auxiliary guide roller has a cylindrical rolling structure. During the laying process, the cable comes into contact with the roller surface. The rolling of the roller reduces the frictional resistance between the cable and the mechanism, preventing the cable from being damaged by friction. At the same time, the roller supports the cable, preventing the cable from sagging due to its own weight and causing the laying path to deviate, ensuring that the laying depth and direction meet the design requirements. The surface of the flat cleaning auxiliary guide roller can be designed with a flexible material with a certain friction. When it rolls in contact with the cable, it can simultaneously wipe away dust, dirt, and other impurities attached to the cable surface. Especially in underground laying scenarios, cleaning the cable surface can prevent impurities from entering the laying pipe with the cable, reducing the risk of pipe blockage, and at the same time preventing impurities from abrading the cable insulation layer, extending the service life of the cable.

[0011] Preferably, the screw is fixedly connected to the bottom output end of the servo control motor, the connecting seat is slidably connected to the surface of the fixed rod, and the connecting seat is threadedly connected to the surface of the screw.

[0012] Preferably, the cable winding cylinder is located at the top center of the main frame, and the second electrically controlled telescopic column and magnetic connector pass through the center of the inside of the cable winding cylinder.

[0013] Compared with the prior art, this utility model provides an underground cable laying structure, which has the following beneficial effects:

[0014] 1. This underground cable laying structure is equipped with an adjustable cable winding cylinder placement mechanism. A servo motor drives a bidirectional screw to rotate, causing the threaded connecting slide to slide laterally along a guide rod, thereby adjusting the spacing between the front and rear support frames. This design can accommodate cable winding cylinders of different lengths, eliminating the need for custom-made brackets for specific cylinder specifications, reducing equipment replacement costs. The first controller controls the extension and retraction of the first electrically controlled telescopic column, causing the connecting plate and sliding seat to move longitudinally along the built-in slide rod. This allows adjustment of the height of the second electrically controlled telescopic column and the magnetic connecting seat, accommodating cable winding cylinders of different diameters and avoiding installation instability caused by differences in cylinder diameter. The second controller controls the extension and retraction of the second electrically controlled telescopic column, which, together with the magnetic connecting seat, inserts into the center of the cable winding cylinder. This allows for quick magnetic fixation of the cylinder and adjustment of the fixing tightness through the extension and retraction force, preventing the cylinder from shaking or shifting during laying. The adjustable groove allows for the adaptation of cable winding cylinders of different specifications, offering strong versatility, reducing operational difficulty, and improving installation efficiency.

[0015] 2. The underground cable laying structure is equipped with a cable leveling adjustment mechanism. A servo-controlled motor drives a screw to rotate, causing the threaded connecting seat to slide laterally along a fixed rod, thereby adjusting the lateral position of the leveling and cleaning auxiliary guide roller. When the cable is released from the cable winding cylinder and laid underground, the roller can adapt to the cable release trajectory by moving laterally, preventing the cable from stacking or tilting due to trajectory deviation, ensuring that the cable is neatly arranged after laying, and reducing the difficulty of sorting during later maintenance. The leveling and cleaning auxiliary guide roller is a cylindrical rolling structure. During the laying process, the cable comes into contact with the roller surface. The rolling of the roller can reduce the frictional resistance between the cable and the mechanism, preventing the cable from being damaged by friction. At the same time, the roller supports the cable, preventing the cable from sagging due to its own weight and causing the laying path to deviate, ensuring that the laying depth and direction meet the design requirements. The surface of the leveling and cleaning auxiliary guide roller can be designed with a flexible material with a certain friction, which can simultaneously wipe away dust, dirt and other impurities attached to the cable surface when rolling in contact with the cable. Especially in underground installations, cleaning the cable surface can prevent impurities from entering the installation pipes along with the cable, reducing the risk of pipe blockage. At the same time, it can prevent impurities from abrading the cable insulation layer and extend the service life of the cable. Attached Figure Description

This design can accommodate cable winding cylinders 5 of different lengths, eliminating the need for custom-made brackets for specific cylinder specifications and reducing equipment replacement costs. The first controller 303 controls the extension and retraction of the first electrically controlled telescopic column 304, which drives the connecting plate 302 and the sliding seat 301 to move longitudinally along the built-in slide rod 39. The height of the second electrically controlled telescopic column 306 and the magnetic connecting seat 307 can be adjusted to accommodate cable winding cylinders 5 of different diameters, avoiding installation instability caused by differences in cylinder diameter. The second controller 305 controls the extension and retraction of the second electrically controlled telescopic column 306, which, together with the magnetic connecting seat 307, is inserted into the center of the cable winding cylinder 5. This allows for quick fixation of the cylinder via magnetic attraction and adjustment of the fixation tightness by telescopic force, preventing the cylinder from shaking or shifting during installation.

[0030] Example 2

[0031] Please see Figure 1-4 Furthermore, based on Embodiment 1, the cable leveling adjustment mechanism 4 includes a first extension plate 41, which is fixedly connected to the bottom of the right rear end of the main frame 1. A second extension plate 42 is fixedly connected to the bottom of the right front end of the main frame 1.

A screw 45 is rotatably connected to the center of the inner end of the first frame 43. A servo control motor 46 is installed at the center of the top of the first frame 43. A fixing rod 47 is fixedly connected to the center of the inner end of the second frame 44. Connecting seats 48 are provided on the surfaces of both the screw 45 and the fixing rod 47. A leveling and cleaning auxiliary guide roller 49 is installed at the inner end of the connecting seat 48. The servo control motor 46 drives the screw 45 to rotate, causing the threaded connecting seat 48 to slide laterally along the fixing rod 47, thereby adjusting the lateral position of the leveling and cleaning auxiliary guide roller 49. When the cable is released from the cable winding cylinder 5 and laid underground, the roller can adapt to the cable release trajectory by moving laterally, preventing the cable from stacking or tilting due to trajectory deviation. This ensures that the cable is neatly arranged after laying, reducing the difficulty of sorting during later maintenance. The flat cleaning auxiliary guide roller 49 has a cylindrical rolling structure. The cable contacts the roller surface during laying. The rolling of the roller reduces the frictional resistance between the cable and the mechanism, preventing the cable from being damaged by friction. At the same time, the roller supports the cable, preventing the cable from sagging due to its own weight and causing the laying path to deviate, ensuring that the laying depth and direction meet the design requirements. The surface of the flat cleaning auxiliary guide roller 49 can be designed as a flexible material with a certain friction. When it rolls in contact with the cable, it can simultaneously wipe away dust, dirt, and other impurities attached to the cable surface. Especially in underground laying scenarios, cleaning the cable surface can prevent impurities from entering the laying pipe with the cable, reducing the risk of pipe blockage, and at the same time preventing impurities from abrading the cable insulation layer, extending the service life of the cable.

[0033] The cable winding cylinder 5 is located at the top center of the main frame 1, and the second electrically controlled telescopic column 306 and the magnetic connector 307 pass through the center of the inside of the cable winding cylinder 5.

[0034] In actual operation, when this device is used, the adjustable cable winding cylinder placement mechanism 3 is adjusted according to the size of the cable winding cylinder 5. The appropriate cable winding cylinder 5 is pushed to the top of the main frame 1 for protection and locked by the adjustable cable winding cylinder placement mechanism 3. The bidirectional screw 33 is driven to rotate by the servo motor 34, which drives the threaded connecting slide 37 to slide laterally along the guide rod 36, thereby adjusting the distance between the front and rear support frames 38. This design can accommodate cable winding cylinders 5 of different lengths, eliminating the need for custom-made brackets for specific cylinder specifications and reducing equipment replacement costs. The first controller 303 controls the extension and retraction of the first electrically controlled telescopic column 304, which drives the connecting plate 302 and the sliding seat 301 to move longitudinally along the built-in slide rod 39. The height of the second electrically controlled telescopic column 306 and the magnetic connecting seat 307 can be adjusted to accommodate cable winding cylinders 5 of different diameters, avoiding installation instability caused by differences in cylinder diameter. The second controller 305 controls the extension and retraction of the second electrically controlled telescopic column 306, which, together with the magnetic connecting seat 307, is inserted into the center of the cable winding cylinder 5. This allows for quick fixation of the cylinder via magnetic attraction and adjustment of the fixation tightness by telescopic force, preventing the cylinder from shaking or shifting during installation. The adjustment slot 31 can accommodate cable winding cylinders 5 of different specifications, making it highly versatile, reducing operational difficulty, and improving installation efficiency.

[0035] The cable passes through the cable leveling and adjusting mechanism 4. The servo-controlled motor 46 drives the screw 45 to rotate, causing the threaded connecting seat 48 to slide laterally along the fixed rod 47, thereby adjusting the lateral position of the leveling and cleaning auxiliary guide roller 49. When the cable is released from the cable winding cylinder 5 and laid underground, the roller can adapt to the release trajectory of the cable by moving laterally, avoiding the cable from stacking or tilting due to trajectory deviation, ensuring that the cable is neatly arranged after laying, and reducing the difficulty of sorting during later maintenance. The leveling and cleaning auxiliary guide roller 49 is a cylindrical rolling structure. The cable comes into contact with the roller surface during the laying process. The rolling of the roller can reduce the frictional resistance between the cable and the mechanism, avoiding damage to the cable due to friction. At the same time, the roller supports the cable, preventing the cable from sagging due to its own weight and causing the laying path to deviate, ensuring that the laying depth and direction meet the design requirements. The surface of the leveling and cleaning auxiliary guide roller 49 can be designed as a flexible material with a certain friction, which can simultaneously wipe away dust, dirt and other impurities attached to the cable surface when rolling in contact with the cable. Especially in underground installation scenarios, cleaning the cable surface can prevent impurities from entering the laying pipes with the cable, reducing the risk of pipe blockage, while also preventing impurities from abrading the cable insulation layer and extending the service life of the cable.

[0036] A winding device is installed at the other end of the underground cable laying to pull the cable out from underground stably and accurately, thereby laying the underground cable.
