Description

Technical Field

[0001] The invention belongs to the technical field of mechanical engineering, and in particular relates to a trench optical cable laying device. Background Art

[0002] With the rapid development of information technology, the coverage and transmission speed of communication networks are constantly improving. As an important carrier for high-speed, large-capacity data transmission, the demand for laying optical cables is growing. In various laying scenarios, trench optical cable laying is one of the common and critical tasks. Underground laying of optical cables is to lay optical cables on the path from one end to the other by directly burying them or in pipes. Pipe laying of optical cables is suitable for some scenarios that require frequent maintenance and replacement. The advantage of underground pipeline laying is that it has good protection and is not affected by the external environment. At the same time, the optical cables can be replaced and maintained at any time as needed.

[0003] In the traditional process of laying optical cables in trenches, manual excavation, laying and landfilling are usually required, which is not only labor-intensive but also inefficient. In addition, when manual excavation encounters special sections, special equipment is required to process the sections, which greatly affects the construction progress and increases the construction cost. In addition, due to the complex environment of the trench, manually laid optical cables are easily damaged, affecting the quality of signal transmission and causing certain losses. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide an adaptive self-moving trench optical cable laying device.

[0005] The technical solution adopted to solve the above technical problems is: an adaptive self-moving trench optical cable laying device, comprising a box body, the top of the box body is rotatably connected to a box door, an air compressor is installed inside the box body, a three-way pipe is installed at the output end of the air compressor, a gas conduit is installed at one end of the three-way pipe, a one-way valve is threadedly connected at the other end of the three-way pipe, two mounting columns are fixedly connected to the inside of the box body near the one-way valve, a reel is connected between the two mounting columns, and a cable is installed on the outer wall of the reel; The other end of the gas conduit is fixedly connected to a traction line, the other end of the traction line is fixedly connected to a connecting buckle, and a main body is installed inside the gas conduit near the connecting buckle; The outer wall of the main body is respectively provided with a clamping and fixing mechanism and a plurality of moving mechanisms, and one side of the main body is fixedly connected with a fixing ring corresponding to the connecting buckle ring.

[0006] Furthermore, an interface corresponding to the cable is provided at the outer end of the one-way valve.

[0007] Through the above technical solution, the cable enters the one-way valve through this interface. When the cable is transmitted into the gas duct, the compressed gas generated by the air compressor will not leak out through the one-way valve, thereby ensuring the smooth progress of the inflation process.

[0008] Furthermore, the clamping and fixing mechanism includes a hollow plate installed inside the main body, the top of the hollow plate is rotatably connected to a threaded rod, the top of the threaded rod is fixedly connected to a rotating wheel, the bottom of the threaded rod is installed with a connecting plate, the interior of the connecting plate is installed with bearings corresponding to the threaded rod, the bottom of the connecting plate is fixedly connected to sliding bars on both sides, the outer walls of the two sliding bars are fixedly connected to two limit plates, the bottoms of the two sliding bars are rotatably connected to a first fixed wheel, the inner wall of the main body is fixedly connected to a plurality of fixing bars, the interior of each of the fixing bars is rotatably connected to a limiting block, and both ends of the limiting block are rotatably connected to a second fixed wheel.

[0009] When the second fixed wheel in contact with the outer wall of the limit plate is displaced, the other second fixed wheel will also move to a corresponding position and move closer to the target cable. Through the cooperation of the first fixed wheel and the second fixed wheel, the target cable is clamped inside the main body, which is convenient for subsequent laying.

[0010] Furthermore, outer walls of the first fixing wheel and one of the second fixing wheels are both in contact with outer walls of the cable.

[0011] Through the above technical solution, by continuously changing the positions of the first fixed wheel and the second fixed wheel, the first fixed wheel and the second fixed wheel can always clamp the cable between the first fixed wheel and the second fixed wheel, thereby ensuring the laying process.

[0012] Furthermore, the outer wall of another of the second fixing wheels is rotatably fitted to the corresponding outer wall of the limiting plate.

[0013] Through the above technical solution, it is ensured that the second fixed wheel rotates along the specific track of the limiting plate, ensuring that the second fixed wheel can clamp the cable according to the specified route, and the limiting plate can prevent the second fixed wheel from excessive or abnormal rotation, ensuring that it operates within the normal working range.

[0014] Furthermore, the moving mechanism includes a base installed on the outer wall of the main body, the base is rotatably connected to a rotating rod inside, the other end of the rotating rod is rotatably connected to a moving wheel, one side of the main body is fixedly connected to a fixed seat corresponding to the base, a rotating column is installed on the top of the fixed seat, a spring is installed inside the rotating column, and the rotating column is slidably connected to a connecting rod inside.

[0015] Through the above technical solution, after the clamping and fixing mechanism on the main body completes the step of clamping the cable, and the connecting buckle is also inserted into the fixing ring, when the main body is placed inside the gas duct, the connecting rod will, under the elastic force of the spring, push the rotating rod outward to expand with the base as the center, until the moving wheel on the rotating rod can contact the inner wall of the gas duct. When the diameter of the gas duct changes, the rotating rod will change synchronously under the joint action of the spring and the connecting rod, so that the rotating rod always fits and rotates on the inner wall of the gas duct to drive the movement of the main body.

[0016] Furthermore, the outer wall of the moving wheel slides on the inner wall of the gas conduit.

[0017] Through the above technical solution, the moving wheels slide on the inner wall of the gas duct, providing a clear movement guide for the moving parts, ensuring that they move accurately along the axial direction of the gas duct, avoiding offset or deviation from the predetermined path. The evenly distributed moving wheels are in contact with the inner wall of the gas duct, so that the moving parts are subjected to more uniform force during movement, reducing jitter and shaking, and enhancing the stability of the entire system.

[0018] Furthermore, the spring is installed between the rotating column and the connecting rod.

[0019] The above technical solution helps to restore the rotating column and the connecting rod to their initial positions after the components are displaced, thereby ensuring the normal working state of the system and enabling the entire assembly to be displaced normally and smoothly.

[0020] The beneficial effects of the present invention are as follows: (1) The present invention designs a clamping and fixing mechanism, and adjusts the distance between the first fixing wheel and the second fixing wheel by continuously rotating the rotating wheel, so that the first fixing wheel and the second fixing wheel can always clamp the optical cable. When the size of the optical cable changes, the optical cable can be clamped by rotating the rotating wheel, which is convenient for the subsequent laying needs of the device. The clamping and fixing mechanism enables the device to clamp different types of optical cables for laying; (2) The present invention designs a moving mechanism. When the gas duct is extended, the moving mechanism will extend or retract in the gas duct to ensure that the moving wheel on the gas duct can always be attached to the inner wall of the gas duct, which is convenient for the auxiliary main body to move. When the diameter or path of the gas duct changes during the extension process, the rotating rod in the moving mechanism will also complete adaptive adjustment under the action of the spring and the connecting rod to ensure the normal movement of the whole. By designing the moving mechanism, the main body can move when facing gas ducts with different diameters and paths, effectively improving the laying efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] like Figure 1 - Figure 5 As shown, an adaptive self-moving trench optical cable laying device of the present embodiment includes a box body 1, a box door 2 is rotatably connected to the top of the box body 1, an air compressor 3 is installed inside the box body 1, a three-way pipe 4 is installed at the output end of the air compressor 3, a gas conduit 5 is installed at one end of the three-way pipe 4, and a one-way valve 6 is threadedly connected to the other end of the three-way pipe 4, two mounting columns 7 are fixedly connected to the inside of the box body 1 near the one-way valve 6, a reel 8 is connected between the two mounting columns 7, a cable 9 is installed on the outer wall of the reel 8, an interface corresponding to the cable 9 is opened at the outer end of the one-way valve 6, the cable 9 enters the one-way valve 6 through the interface, when the cable 9 is transmitted to the inside of the gas conduit 5, the compressed gas generated by the air compressor 3 will not leak out through the one-way valve 6, so as to ensure the smooth progress of the inflation process, a traction line 10 is fixedly connected to the other end of the gas conduit 5, a connecting buckle 11 is fixedly connected to the other end of the traction line 10, and a main body 12 is installed near the connecting buckle 11 inside the gas conduit 5.

[0025] like Figure 6 and Figure 7As shown, the outer wall of the main body 12 is provided with a clamping and fixing mechanism 13, and the clamping and fixing mechanism 13 includes a hollow plate 1301 installed inside the main body 12, the top of the hollow plate 1301 is rotatably connected to a threaded rod 1302, the top of the threaded rod 1302 is fixedly connected to a rotating wheel 1303, the bottom of the threaded rod 1302 is installed with a connecting plate 1304, the interior of the connecting plate 1304 is installed with a bearing 1305 corresponding to the threaded rod 1302, the bottom of the connecting plate 1304 is fixedly connected to sliding bars 1306 on both sides, the outer walls of the two sliding bars 1306 are fixedly connected to two limit plates 1307, the bottoms of the two sliding bars 1306 are rotatably connected to a first fixed wheel 1308, the inner wall of the main body 12 is fixedly connected to a plurality of fixing bars 1309, and the interior of each fixing bar 1309 is rotatably connected to a limit block 1310, and the limit block Both ends of 1310 are rotatably connected with second fixed wheels 1311, and the outer walls of the first fixed wheel 1308 and one of the second fixed wheels 1311 are both fitted to the outer wall of the cable 9. By continuously adjusting the positions of the first fixed wheel 1308 and the second fixed wheel 1311, the first fixed wheel 1308 and the second fixed wheel 1311 can always clamp the cable 9 between the first fixed wheel 1308 and the second fixed wheel 1311 to ensure the laying process. The outer wall of the other second fixed wheel 1311 is fitted and rotated to the corresponding outer wall of the limiting plate 1307 to ensure that the second fixed wheel 1311 rotates along the specific trajectory of the limiting plate 1307, ensuring that the second fixed wheel 1311 can clamp the cable 9 along the specified route, and the limiting plate 1307 can prevent the second fixed wheel 1311 from excessive or abnormal rotation, ensuring that it operates within a normal working range; When the target cable 9 is connected to the main body 12, the threaded rod 1302 is driven to rotate by rotating the rotating wheel 1303. At this time, the threaded rod 1302 will drive the connecting plate 1304 to move. Since the connecting plate 1304 is equipped with a bearing 1305, the threaded rod 1302 will only drive the connecting plate 1304 to move, but will not drive the connecting plate 1304 to rotate. When the connecting plate 1304 moves, the sliding bar 1306 will be pressed synchronously, forcing the first fixed wheel 1308 under the sliding bar 1306 to move toward the target cable 9. During the pressing movement, the two limit plates 1307 on the outer wall of the sliding bar 1306 will also be pressed down, and the second fixed wheel 1311 rolling on the outer wall of the limit plate 1307 will also move. Since the limit block 1310 can only rotate around the fixed point of the fixed bar 1309, when the second fixed wheel 1311 in contact with the outer wall of the limit plate 1307 is displaced, the other second fixed wheel 1311 will also move to a corresponding position and move closer to the target cable 9. Through the cooperation of the first fixed wheel 1308 and the second fixed wheel 1311, the target cable 9 is clamped inside the main body 12, which is convenient for subsequent laying.

[0026] like Figure 8 and Fig. 9 As shown, the outer wall of the main body 12 is provided with a plurality of moving mechanisms 14, and the moving mechanism 14 includes a base 1401 installed on the outer wall of the main body 12, and the base 1401 is internally rotatably connected to a rotating rod 1402, and the other end of the rotating rod 1402 is rotatably connected to a moving wheel 1403, and the outer wall of the moving wheel 1403 slides on the inner wall of the gas conduit 5, and the moving wheel 1403 slides on the inner wall of the gas conduit 5, which provides a clear movement guide for the moving part, ensuring that it moves accurately along the axial direction of the gas conduit 5, and avoids deviation or In case of deviation from the predetermined path, the evenly distributed moving wheels 1403 contact the inner wall of the gas conduit 5, so that the moving parts are subjected to more uniform force during movement, reducing jitter and shaking, and enhancing the stability of the entire system. A fixed seat 1404 corresponding to the base 1401 is fixedly connected to one side of the main body 12, and a rotating column 1405 is installed on the top of the fixed seat 1404. A spring 1406 is installed inside the rotating column 1405. The spring 1406 is installed between the rotating column 1405 and the connecting rod 1407, which is helpful for the movement of the parts. After the displacement of the component, the rotating column 1405 and the connecting rod 1407 are restored to the initial position to ensure the normal working state of the system, so that the entire component can be displaced normally and smoothly. The internal sliding connection of the rotating column 1405 is connected to the connecting rod 1407, and one side of the main body 12 is fixedly connected to a fixing ring 15 corresponding to the connecting buckle 11. After the clamping and fixing mechanism 13 on the main body 12 completes the step of clamping the cable 9, and the connecting buckle 11 is also sleeved into the fixing ring 15, the main body 12 is placed inside the gas conduit 5. Afterwards, the connecting rod 1407 will, under the elastic force of the spring 1406, push the rotating rod 1402 to expand outward with the base 1401 as the center, until the moving wheel 1403 on the rotating rod 1402 can contact the inner wall of the gas duct 5. When the diameter of the gas duct 5 changes, the rotating rod 1402 will change synchronously under the joint action of the spring 1406 and the connecting rod 1407, so that the rotating rod 1402 always rotates in close contact with the inner wall of the gas duct 5 to drive the movement of the main body 12.

[0027] The working principle of this embodiment is as follows. The staff needs to install the reel 8 for laying the cable 9 into the two installation columns 7, remove the one-way valve 6, pass one end of the cable 9 through the special opening of the one-way valve 6, and move it toward the inside of the main body 12. When one end of the cable 9 completely enters the inside of the main body 12, the rotating wheel 1303 is rotated to drive the threaded rod 1302 to rotate, and the position of the connecting plate 1304 inside the hollow plate 1301 is adjusted by continuously controlling the direction and number of turns of the threaded rod 1302, forcing the first fixed wheel 1308 under the sliding bar 1306 to move toward the target cable 9 until the first fixed wheel 1308 completely contacts the outer wall of the cable 9. When the fixed wheel 1308 moves, the two limit plates 1307 on the outer wall of the sliding bar 1306 will also be pressed down, and the second fixed wheel 1311 rolling on the outer wall of the limit plate 1307 will also move. When the second fixed wheel 1311 in contact with the outer wall of the limit plate 1307 is displaced, the other second fixed wheel 1311 will also move to a corresponding position and move closer to the target cable 9. Through the cooperation of the first fixed wheel 1308 and the second fixed wheel 1311, the target cable 9 is clamped inside the main body 12. At this time, the connecting buckle 11 is buckled onto the fixing ring 15. After the one-way valve 6 is rotated to the specified position, the air compressor 3 is started to inflate the gas conduit 5. After receiving the pressure of compressed air, the gas duct 5 will continue to stretch, and the connecting buckle 11 with the traction line 10 at the other end of the gas duct 5 will move with the main body 12. The moving mechanism 14 on the main body 12 will, under the elastic force of the spring 1406, push the rotating rod 1402 to expand outward with the base 1401 as the center point until the moving wheel 1403 on the rotating rod 1402 can contact the inner wall of the gas duct 5. The main body 12 will continue to move with the stretching of the gas duct 5, and will also lay the cable 9 inside it. When the gas duct 5 is fully stretched, the cable 9 will also be laid. At this time, one end of the gas duct 5 installed on the box 1 is removed from the box 1, and the gas duct 5 and the main body 12 are collected to complete the laying of the cable 9.
