Description

Technical Field

[0001] The present invention relates to the technical field of cable laying, and in particular to an optical cable laying device and a laying method thereof. Background Art

[0002] Optical cable, a general term for both optical and electrical cables, primarily utilizes optical fibers to transmit light signals. Featuring high transmission capacity, high speed, and strong anti-interference capabilities, optical cable is widely used in long-distance communications, internet backbone networks, and other fields. With the rapid development of communications technology and the power industry, the demand for laying optical cables is growing. Trenching is a crucial step in laying optical cables underground. If there are protrusions or rocks at the bottom of the trench, a layer of loose soil is laid to prevent direct contact between the cables and hard objects, providing physical protection.

[0003] However, in traditional technology, loosening the soil and laying cables in the trench are usually two independent processes, which require different equipment and manpower to operate respectively. This not only leads to low construction efficiency and increased construction costs, but also the step-by-step operation is prone to problems such as accumulation of debris and unevenness at the bottom of the trench due to long intervals, affecting the laying quality and protection effect of the optical cable, and easily causing the position of the optical cable to deviate from the designed path, resulting in uneven force on the optical cable and conflict with other pipelines. If the distance between two adjacent optical cables is small, it is easy for electromagnetic induction to generate induced voltage in the optical cable, affecting the stability of the optical cable transmission.

[0044] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0045] like Figures 1 to 11As shown, an optical cable laying device of the present invention includes a vehicle body 10, a mounting seat 11 is connected to the vehicle body 10, and a loosening laying structure that moves along the length direction of the vehicle body 10 is provided on the mounting seat 11. The loosening laying structure is used to lay loose soil inside the trench. The two symmetrical side surfaces of the mounting seat 11 are rotatably connected to the rotating shaft 12, and the outer surfaces of the two rotating shafts 12 are fixedly connected to the rotating plates 13. Two mounting slide rods 14 are fixedly connected to the opposite side of the two rotating plates 13. The length direction of the mounting slide rod 14 is parallel to the width direction of the vehicle body 10. At least two sets of guide wheel structures are movably installed on each installation slide 14, and the guide wheel structure is used to guide the optical cable. Each set of guide wheel structures is provided with a telescopic structure, and each set of telescopic structures is rotatably connected to a limiting roller 20. The limiting roller 20 is used to limit the optical cable to avoid position displacement of the optical cable. A driving connector is provided between each rotating shaft 12 and the mounting seat 11, and the driving connector is connected to the loosening and laying structure. The driving connector is used to move the loosening and laying structure while causing the rotating shaft 12 to drive the installation slide 14 to rotate.

[0046] Before laying the optical cable, if the trench is uneven and loose soil needs to be laid inside the trench, the loose soil laying structure is located in front of the limiting roller 20, and the guide wheel structure is located between the loose soil laying structure and the limiting roller 20. In the process of laying the optical cable, the loose soil is first transported to the inside of the trench by the loose soil laying structure, and then the optical cable is laid. If the trench is flat and there is no need to lay the loose soil before laying the cable, the rotating shaft 12 drives the rotating plate 13 to rotate forward by driving the connecting piece. At this time, the loose soil laying structure moves backward so that the rotating plate 13 and the limiting roller 20 are located in front of the loose soil laying structure. At this time, the loose soil can be laid after the optical cable is laid, so that the operations of laying the loose soil and laying the optical cable can be carried out simultaneously, thereby improving the efficiency of laying the optical cable.

[0047] It should be noted that a through groove is provided on the mounting seat 11, the length of which is greater than the overall thickness of the loosening paving structure, so that when the loosening paving structure moves to the rear of the vehicle body 10, the telescopic structure and the limiting roller 20 can pass through the through groove and extend to the bottom of the mounting seat 11.

[0048] like Figure 1 and Figure 7-10 The guide wheel structure includes a sleeve 30 slidably arranged on the outer surface of the two mounting slide bars 14. The outer surface of each sleeve 30 is rotatably connected to a guide wheel 31. The optical cable passes between the two guide wheels 31, and the guide wheel 31 is transmission-connected to the optical cable. The outer surface of each sleeve 30 is rotatably connected to a rotating sleeve 32. A fixed component is provided between each rotating sleeve 32, the sleeve 30 and the mounting slide bar 14.

[0049] The fixing assembly includes a plurality of fixing sockets 141 opened on the outer surface of the mounting slide rod 14 and a plurality of fixing sockets 2 321 opened on the outer surface of the rotating sleeve 32. A fixing bolt 33 passes through and is threadedly connected to the sleeve 30. A fixing nut is threadedly connected to the outer surface of the fixing bolt 33. The fixing bolt 33 passes between the fixing socket 1 141 and the fixing socket 2 321.

[0050] Before laying the optical cable, the position of the sleeve 30 is adjusted according to the distance between two adjacent optical cables. At this time, the guide wheel 31, the telescopic structure and the limiting roller 20 move accordingly. Since the optical cable passes between the guide wheels 31, the positions of the guide wheels 31 and the limiting roller 20 are adjusted according to the actual situation during use, so that the distance between the optical cables can be adjusted. Then, the fixing bolt 33 is passed through the fixing hole 141 and the fixing hole 2 321, and then the fixing nut is connected to the fixing bolt 33, so as to fix the sleeve 30 and the rotating sleeve 32. At this time, the positions of the guide wheel 31 and the limiting roller 20 no longer move. At this time, the guide wheel 31 and the limiting roller 20 can be used to limit the optical cable and perform the operation of laying the optical cable.

[0051] It should be noted that the cross-sectional shape of the sleeve 30 is I-shaped, and the guide wheel 31 is located between the two rotating sleeves 32. One side of the rotating sleeve 32 fits into the end of the sleeve 30. The sleeve 30 can ensure the smooth rotation of the rotating sleeve 32 while avoiding positional offset between the rotating sleeve 32 and the guide wheel 31.

[0052] like Figure 7-Figure 9 The telescopic structure includes a rotating frame 34 connected to the outer surface of the rotating sleeve 32 and having a hollow structure inside. An adjusting bolt 35 is threadedly connected to one side of the rotating frame 34, and an adjusting nut is threadedly connected to the outer surface of the adjusting bolt 35. An extension rod 36 is slidably connected to the inside of the rotating frame 34. A plurality of adjusting holes 361 are evenly opened on one side of the extension rod 36. The adjusting bolt 35 passes through the adjusting holes 361, and the limiting roller 20 is rotatably connected to the end of the extension rod 36.

[0053] When using the limiting roller 20 to limit the optical cable, the rotating sleeve 32 drives the rotating frame 34 to rotate according to the actual situation during use. At this time, the extension rod 36 drives the limiting roller 20 to rotate, adjusts the angle of the limiting roller 20, and then fixes the rotating sleeve 32 through the fixing assembly. Then, the extension rod 36 is moved out from the inside of the rotating frame 34 and the limiting roller 20 is in contact with the inner wall of the channel. Then, the adjusting bolt 35 is passed through the adjusting hole 361, and finally, the adjusting nut is tightly fitted with the adjusting bolt 35 and the adjusting nut is fitted with the rotating frame 34, thereby fixing the extension rod 36. At this time, the optical cable can be stably limited by the limiting roller 20 to avoid position displacement of the optical cable.

[0054] When the rotating shaft 12 drives the rotating plate 13 to move forward, the extension rod 36 can be retracted into the interior of the rotating frame 34, and the rotating frame 34 can be adjusted to above the guide wheel structure, so as to avoid interference between the telescopic structure and the limiting roller 20 and the loosening and laying structure, ensuring that the telescopic structure and the installation slide bar 14 rotate smoothly, and after the telescopic structure and the installation slide bar 14 rotate to a certain angle, the telescopic structure and the limiting roller 20 are readjusted so that the limiting roller 20 passes through the grooves opened on the mounting seat 11 and performs a limiting operation on the optical cable.

[0055] like Figure 1-Figure 7 The driving connection includes a linear module 15 installed on the top side of the mounting seat 11. The length direction of the linear module 15 is parallel to the length direction of the vehicle body 10. The linear module 15 is provided with a slide 16 that moves along the length direction of the linear module 15. The slide 16 is connected to the loosening paving structure. A transmission rack 17 is connected to one side of the slide 16. The length direction of the transmission rack 17 is parallel to the length direction of the vehicle body 10. The outer surface of the transmission rack 17 is engaged with a transmission gear 18 connected to the rotating shaft 12.

[0056] If the trench is uneven and it is necessary to lay loose soil inside the trench, the guide wheel structure is located between the loose soil laying structure and the limiting roller 20. At this time, the loose soil laying and optical cable laying operations are performed in sequence inside the trench. If the trench is flat and there is no need to lay loose soil before laying the cable, the slide 16 is moved by the linear module 15, and the slide 16 is moved toward the rear of the vehicle body 10. At this time, the loose soil laying structure moves toward the rear of the vehicle body 10. At this time, under the transmission action of the transmission rack 17 and the transmission gear 18, the rotating shaft 12 drives the rotating plate 13 to move forward, and the limiting roller 20 is located between the guide wheel structure and the loose soil laying structure, so that the loose soil laying operation can be performed after laying the optical cable.

[0057] like Figure 5-Figure 6 The loosening and paving structure includes a loosening box 40 connected to the slide 16, and the bottom end of the loosening box 40 is connected to a feeding hopper 41. A sealing component is provided on the feeding hopper 41, and the sealing component is used to block the discharge port of the feeding hopper 41. A paving component is provided between the feeding hopper 41 and the loosening box 40, and the paving component is used to spread the loose soil transported by the discharge port of the feeding hopper 41 to make the thickness of the loose soil more uniform. The paving component is located between the sealing component and the limiting roller 20, and the sealing component is located in front of the paving component.

[0058] The sealing assembly includes an electric push rod 42 hinged to one side of the feed hopper 41 and a sealing plate 43 rotatably connected to the bottom end of the feed hopper 41. The output end of the electric push rod 42 is hinged to the sealing plate 43. The sealing plate 43 corresponds to the position of the discharge port of the feed hopper 41. The size of the sealing plate 43 is larger than the size of the discharge port of the feed hopper 41.

[0059] Under normal conditions, the blocking plate 43 blocks the discharge port of the feed hopper 41 to prevent the loose soil inside the loosening box 40 from falling. When loose soil needs to be laid, the angle of rotation of the blocking plate 43 is controlled by controlling the extension length of the output end of the electric push rod 42, thereby controlling the falling speed of the loose soil inside the loosening box 40 and the amount of loose soil laid inside the ditch, and better avoiding the situation where too much or too little loose soil enters the ditch, so that the effect of paving the loose soil is better.

[0060] The paving assembly includes a mounting frame 44 rotatably connected to the side of the feed hopper 41 away from the electric push rod 1 42, and a paving roller 45 rotatably connected to one side of the mounting frame 44. The paving roller 45 corresponds to the discharge port position of the feed hopper 41. An electric push rod 2 46 is hinged to one side of the loosening box 40, and the output end of the electric push rod 2 46 is hinged to the mounting frame 44.

[0061] By controlling the length of the output end of the electric push rod 46 to adjust the rotation angle of the mounting frame 44, the height of the paving roller 45 can be adjusted, and the thickness of the loose soil inside the ditch can be controlled according to the actual situation during use, further avoiding the situation of too much or too little loose soil inside the ditch.

[0062] It should be noted that the length of the discharge port of the feed hopper 41 is smaller than the width of the groove opened on the mounting seat 11, and the discharge port of the feed hopper 41 is located below the mounting seat 11, thereby ensuring that the feed hopper 41 can move smoothly while smoothly delivering the loose soil into the channel.

[0063] like Figure 1 and Figure 11 A support frame 50 is installed on the mounting seat 11, and a winding roller 51 is rotatably connected to the support frame 50. The winding roller 51 can retract and release at least two optical cables. A driving structure 52 is provided on the support frame 50, and the driving structure 52 is used to drive the winding roller 51 to rotate.

[0064] The driving structure 52 can be a belt drive, gear drive or other structure. The driving structure 52 drives the winding roller 51 to rotate and perform the unwinding operation, thereby gradually lowering the optical cable and performing the operation of laying the optical cable.

[0065] A method for laying an optical cable comprises the following steps:

[0066] S1. Move the sleeve 30, and the guide wheel 31, the telescopic structure, and the limiting roller 20 move accordingly. The positions of the guide wheel 31 and the limiting roller 20 are adjusted according to the spacing between adjacent optical cables.

[0067] S2. The rotating sleeve 32 drives the rotating frame 34 to rotate. At this time, the extension rod 36 drives the limiting roller 20 to rotate and adjust the angle of the limiting roller 20;

[0068] S3, pass the fixing bolt 33 through the fixing hole 141 and the fixing hole 2 321, and then connect the fixing nut to the fixing bolt 33, thereby fixing the sleeve 30 and the rotating sleeve 32;

[0069] S4, moving the extension rod 36 out from the interior of the rotating frame 34 and making the limiting roller 20 contact the inner wall of the channel;

[0070] S5. Pass the adjusting bolt 35 through the adjusting hole 361, and fit the adjusting nut tightly against the adjusting bolt 35 and the adjusting nut against the rotating frame 34, thereby fixing the extension rod 36.

[0071] S6, passing the optical cable between the two guide wheels 31 and into the interior of the limiting roller 20;

[0072] S7: Control the extension of the output end of the second electric push rod 46 to adjust the height of the paving roller 45, and control the opening and closing degree of the blocking plate 43 by controlling the length of the output end of the first electric push rod 42. At this time, the loose soil in the loosening box 40 enters the channel through the discharge port of the feeding hopper 41;

[0073] S8. Move the vehicle body 10 and use the driving structure 52 to make the winding roller release the optical cable. The optical cable will be laid on the loose soil inside the trench, thereby performing the operations of spreading the loose soil and the optical cable at the same time.
