Description

Technical Field

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

[0002] Optical cables are a general term for optical fiber cables and electric cables. Optical fiber cables mainly use optical fibers to transmit optical signals, and have characteristics such as large transmission capacity, high speed, and strong anti-interference ability, and are widely used in fields such as long-distance communication and Internet backbone networks. With the rapid development of communication technology and the power industry, the demand for laying optical cables is increasing day by day. When laying optical cables underground, trench digging is an important link in laying optical cables. After trench digging, if there are protrusions or stones at the bottom of the trench, a layer of loose soil needs to be laid at the bottom of the trench to prevent the optical cable from directly contacting hard objects, playing a physical protection role.

[0003] However, in traditional technologies, laying loose soil and laying cables in the trench are usually two independent processes, which require different equipment and manual operations 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 debris accumulation and unevenness at the bottom of the trench due to too long an interval time, affecting the laying quality and protection effect of optical cables, and easily causing the position of the optical cable to deviate from the designed path, resulting in uneven stress on the optical cable and conflicts with other pipelines. If the distance between two adjacent optical cables is small, induced voltage is easily generated in the optical cable due to electromagnetic induction, affecting the transmission stability of the optical cable. Summary of the Invention

[0029] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention

[0030] As Figures 1 to 11 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. A soil loosening and laying structure that moves along the length direction of the vehicle body 10 is provided on the mounting seat 11. The soil loosening and laying structure is used for laying loose soil inside the trench. Rotating shafts 12 are rotatably connected to two opposite side surfaces of the mounting seat 11. Rotating plates 13 are fixedly connected to the outer surfaces of the two rotating shafts 12. Two mounting slide bars 14 are fixedly connected to one side of the two rotating plates 13 facing each other. The length direction of the mounting slide bars 14 is parallel to the width direction of the vehicle body 10. At least two groups of guiding wheel structures are movably mounted on the two mounting slide bars 14. The guiding wheel structures are used for guiding the optical cable. A telescopic structure is provided on each group of guiding wheel structures. A limiting roller 20 is rotatably connected to each telescopic structure. The limiting roller 20 is used for limiting the optical cable to prevent the optical cable from shifting in position. A driving connecting piece is provided between each rotating shaft 12 and the mounting seat 11. The driving connecting piece is connected to the soil loosening and laying structure. The driving connecting piece is used for driving the soil loosening and laying structure to move while driving the rotating shaft 12 to drive the mounting slide bar 14 to rotate

[0031] Before laying the optical cable, if the channel is uneven and it is necessary to lay loose soil inside the channel, at this time, 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. During the process of laying the optical cable, first, the loose soil is conveyed into the channel through the loose soil laying structure, and then the operation of laying the optical cable is carried out. If the channel is flat and there is no need to lay loose soil before laying the cable, the rotating shaft 12 is driven by the driving connecting piece to drive the rotating plate 13 to rotate forward. 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 laying the optical cable, so that the operations of laying loose soil and laying the optical cable can be carried out simultaneously, improving the efficiency of laying the optical cable.

[0032] It should be noted that a through groove is opened on the mounting seat 11, and the length of the through groove is greater than the overall thickness of the loose soil laying structure, so that when the loose soil laying 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 below the mounting seat 11.

[0033] Such as Figure 1 and Figures 7 - 10 , the guide wheel structure includes sleeves 30 slidably arranged on the outer surfaces of two mounting slide rods 14. A guide wheel 31 is rotatably connected to the outer surface of each sleeve 30. The optical cable passes between the two guide wheels 31, and the guide wheel 31 is in driving connection with the optical cable. A rotating sleeve 32 is rotatably connected to the outer surface of each sleeve 30, and a fixing component is arranged between each rotating sleeve 32, sleeve 30 and the mounting slide rod 14.

[0034] The fixing component includes a plurality of fixing jacks one 141 opened on the outer surface of the mounting slide rod 14 and a plurality of fixing jacks two 321 opened on the outer surface of the rotating sleeve 32. A fixing bolt 33 is penetrated and threadedly connected to the sleeve 30. A fixing nut is threadedly connected to the outer surface of the fixing bolt 33, and the fixing bolt 33 passes through between the fixing jack one 141 and the fixing jack two 321.

[0035] Before laying the optical cable, the position of the sleeve 30 is adjusted according to the distance between adjacent two 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 wheel 31 and the limiting roller 20 are adjusted according to the actual situation during use, so as to be able to adjust the distance between the optical cables. Then, the fixing bolt 33 is passed through the fixing jack one 141 and the fixing jack two 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 optical cable can be limited by the guide wheel 31 and the limiting roller 20 and the operation of laying the optical cable can be carried out.

[0036] 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.

[0037] like Figures 7 - 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.

[0038] 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.

[0039] 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.

[0040] like Figures 1 - 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.

[0041] If the channel is uneven and it is necessary to lay loose soil inside the channel, at this time, the guide wheel structure is located between the loose soil laying structure and the limit roller 20. At this time, the operations of laying loose soil and laying optical cables are carried out in sequence inside the channel. If the channel is flat and there is no need to lay loose soil before laying the cable, the sliding seat 16 is moved by the linear module 15, and the sliding seat 16 is moved towards the rear of the vehicle body 10. At this time, the loose soil laying structure moves towards the rear of the vehicle body 10. At this time, under the driving action of the driving rack 17 and the driving gear 18, the rotating shaft 12 drives the rotating plate 13 to move forward, and the limit roller 20 is located between the guide wheel structure and the loose soil laying structure, so that the operation of laying loose soil can be carried out after laying the optical cable.

[0042] Such as Figures 5 - 6 , the loose soil laying structure includes a loose soil box 40 connected to the sliding seat 16. A feeding hopper 41 is connected to the bottom end of the loose soil box 40. A blocking component is arranged on the feeding hopper 41, and the blocking component is used to block the discharge port of the feeding hopper 41. A spreading component is arranged between the feeding hopper 41 and the loose soil box 40, and the spreading component is used to spread the loose soil conveyed by the discharge port of the feeding hopper 41, so that the thickness of the loose soil is relatively uniform. The spreading component is located between the blocking component and the limit roller 20, and the blocking component is located in front of the spreading component.

[0043] The blocking component includes an electric push rod 42 hinged to one side of the feeding hopper 41 and a blocking plate 43 rotatably connected to the bottom end of the feeding hopper 41. The output end of the electric push rod 42 is hinged to the blocking plate 43. The blocking plate 43 corresponds to the position of the discharge port of the feeding hopper 41, and the size of the blocking plate 43 is larger than the size of the discharge port of the feeding hopper 41.

[0044] In the normal state, the blocking plate 43 blocks the discharge port of the feeding hopper 41 to prevent the loose soil inside the loose soil box 40 from falling. When it is necessary to lay loose soil, the rotation angle of the blocking plate 43 is controlled by controlling the extension length of the output end of the electric push rod 42, so that the falling speed of the loose soil inside the loose soil box 40 and the amount of loose soil laid into the channel can be controlled, which can better avoid the situation of too much or too little loose soil entering the channel, and make the effect of spreading loose soil better.

[0045] The spreading component includes a mounting frame 44 rotatably connected to the side of the feeding hopper 41 away from the electric push rod 42. A spreading roller 45 is rotatably connected to one side of the mounting frame 44. The spreading roller 45 corresponds to the position of the discharge port of the feeding hopper 41. An electric push rod 46 is hinged to one side of the loose soil box 40, and the output end of the electric push rod 46 is hinged to the mounting frame 44.

[0046] By controlling the length of the output end of the second electric push rod 46, the rotation angle of the mounting bracket 44 is adjusted, so that the height of the paving roller 45 can be adjusted, and the thickness of the loosened soil in the channel can be controlled according to the actual situation during use, further avoiding the situation of too much or too little loosened soil in the channel.

[0047] It should be noted that the length of the discharge port of the feeding hopper 41 is less than the width of the through groove opened on the mounting seat 11, and the discharge port of the feeding hopper 41 is located below the mounting seat 11, so as to ensure that the feeding hopper 41 can smoothly move while smoothly feeding the loosened soil into the channel.

[0048] Such as Figure 1 and Figure 11 As shown in and, a support frame 50 is installed on the mounting seat 11, a winding roller 51 is rotatably connected to the support frame 50, and the number of optical cables that the winding roller 51 can wind and unwind is at least two. A driving structure 52 is arranged on the support frame 50, and the driving structure 52 is used to drive the winding roller 51 to rotate.

[0049] The driving structure 52 can be a belt drive, a gear drive and other structures. The driving structure 52 is used to drive the winding roller 51 to rotate and perform a pay-out operation, so as to gradually lower the optical cable and perform the operation of laying the optical cable.

[0050] A method for laying an optical cable includes the following steps: S1. Move the sleeve 30. At this time, the guide wheel 31, the telescopic structure and the limit roller 20 move accordingly, and the positions of the guide wheel 31 and the limit roller 20 are adjusted according to the distance between adjacent optical cables. S2. Make the rotating sleeve 32 drive the rotating frame 34 to rotate. At this time, the extension rod 36 drives the limit roller 20 to rotate, and the angle of the limit roller 20 is adjusted. S3. Make the fixing bolt 33 pass through the first fixing jack 141 and the second fixing jack 321, and then connect the fixing nut to the fixing bolt 33, so as to fix the sleeve 30 and the rotating sleeve 32. S4. Move the extension rod 36 out of the inside of the rotating frame 34 and make the limit roller 20 contact the inner wall of the channel. S5. Make the adjusting bolt 35 pass through between the adjusting jacks 361, and make the adjusting nut fit tightly with the adjusting bolt 35 and make the adjusting nut fit with the rotating frame 34, so as to fix the extension rod 36. S6. Make the optical cable pass through between the two guide wheels 31 and enter the inside of the limit roller 20. S7. Control the output end of the second electric push rod 46 to extend to adjust the height of the paving roller 45, and control the opening and closing degree of the sealing plate 43 by controlling the length of the output end of the first electric push rod 42. At this time, the loosened soil in the loosened soil box 40 enters the channel from the discharge port of the feeding hopper 41. S8. Move the vehicle body 10 and let the cable reel release the optical cable through the drive structure 52. The optical cable will be laid on the loose soil inside the trench, so as to simultaneously carry out the operations of spreading the loose soil and laying the optical cable.
