Description

Technical Field

[0001] The present application relates to the technical field of laying communication optical cables, and in particular to a laying device and a laying method for communication optical cables. Background Art

[0002] With the rapid development of communication technology, the demand for laying communication optical cables is increasing. At present, the laying of communication optical cables mainly relies on manual or semi-automatic equipment. However, in complex environments, traditional laying methods are inefficient and prone to damage to optical cables. In recent years, automated laying technology has gradually emerged, but there are still problems such as inaccurate positioning and slow laying speed.

[0003] In the existing technology, the laying of communication optical cables mainly adopts the following methods: manual laying: the laying is completed by manually pulling the optical cable, which has the advantage of high flexibility and the disadvantage of low efficiency and high labor intensity; mechanical traction laying: the optical cable is pulled into the pipeline by a traction machine, which has the advantage of high speed and the disadvantage of high requirements for the curvature of the pipeline. Mechanical traction laying is sensitive to the curvature of the pipeline and can easily cause wear of the optical cable; air blowing laying: the optical cable is blown into the pipeline by high-pressure airflow. The advantage is that it is suitable for long-distance laying, but the disadvantage is that the equipment cost is high and the sealing requirements for the pipeline are strict, and it is not suitable for complex environments. In addition, the protection measures for the optical cable during the laying process are insufficient, which makes the optical cable vulnerable to external damage after laying, resulting in high subsequent maintenance costs. Summary of the Invention

[0004] The purpose of the present application is to provide a laying device and a laying method for communication optical cables.

[0005] In a first aspect, the present application provides a device for laying communication optical cables using the following technical solutions: The top outer wall of the movable frame is fixedly connected to the inner wall of the cable storage bin, and the middle inner wall of the cable storage bin is fixedly connected to the movable frame. The top of the movable frame is connected to the rotating shaft through a bearing, and the middle outer wall of the rotating shaft is sleeved with a cable winding drum. A sliding rod is provided on one side of the cable winding drum, and the sliding rod is fixedly connected to the inner wall of one side of the cable storage bin, and the outer wall of the sliding rod is slidably connected to a movable block, and the top outer wall of the movable block is fixedly connected to a connecting seat, and the top outer wall of the connecting seat is provided with a limiting groove, and the middle part of the limiting groove is connected to a bidirectional threaded rod through a bearing, and the opposite threads on both sides of the bidirectional threaded rod are threadedly connected to threaded moving blocks, and the top outer walls of two groups of the threaded moving blocks are fixedly connected to the limiting frames, and the two groups of the limiting frames are arranged opposite to each other.

[0006] By adopting the above technical solution, the base plays a supporting role. The optical cable take-up reel is sleeved on the rotating shaft and placed on the movable frame. The bidirectional threaded rod can rotate in the limit groove. At the same time, the threaded moving block is slidably connected to the limit groove to prevent the threaded moving block from rotating. The connecting seat plays a connecting role. The two limit frames are arranged oppositely, and their inner walls cooperate to form an arc shape to facilitate guiding the optical cable. At the same time, during the guiding process, the movable block can move to a certain extent following the different traction positions of the optical cable, reducing the access angle of the optical cable and avoiding entanglement of the optical cable during traction, improving the laying efficiency of the communication optical cable in a complex environment and reducing damage to the optical cable during laying.

[0007] One side outer wall of the connecting seat is provided with an adjusting knob, and the adjusting end of the adjusting knob is connected to the bidirectional threaded rod. The bottom outer wall of one limit frame close to the adjusting knob is fixedly connected with a telescopic strip, and the bottom outer wall of the opposite limit frame is provided with a telescopic groove. The telescopic strip and the telescopic groove are arranged correspondingly, and one end of the telescopic strip is embedded in the telescopic groove. Auxiliary balls are embedded in the top outer wall of the telescopic strip and the inner walls of the two limit frames.

[0008] By adopting the above technical solution, manually rotating the adjusting knob can drive the bidirectional threaded rod to rotate synchronously. The opposite threads of the bidirectional threaded rod drive the two threaded moving blocks to move towards each other along the limit groove. The two limit frames move inwards synchronously with the threaded moving blocks and gradually clamp both sides of the optical cable take-up reel. When the distance between the limit frames is reduced to a certain value, the telescopic strip is inserted into the telescopic groove of the opposite limit frame to form a rigid connection. When the optical cable is released, the surface of the optical cable take-up reel rolls into contact with the auxiliary balls on the inner wall of the limit frame, reducing the frictional resistance.

[0009] A traction module is arranged on one side of the optical cable storage bin. The traction module includes a traction frame, a first traction shaft, a second traction shaft, a traction wheel and a traction motor. The traction frame is arranged on one side of the optical cable storage bin. One side of the top of the traction frame is connected to the first traction shaft through a bearing. A second traction shaft is arranged on one side of the first traction shaft, and the second traction shaft is also directly connected to the traction frame through a bearing. Both the middle outer walls of the first traction shaft and the second traction shaft are fixedly connected with traction wheels. The two traction wheels are on the same straight line, and a buffer pad is arranged on the surface of the traction wheels.

[0010] By adopting the above technical solution, the two traction wheels are respectively fixed on independent first and second traction shafts and are on the same straight line. The optical cable passes through between the two wheels to form symmetric clamping traction. The surface of the traction wheels is completely covered with buffer pads, converting the rigid contact into elastic pressing, realizing pressure dispersion, reducing the contact surface pressure, and decreasing the indentation rate on the surface of the optical cable, providing protection for the integrity of the sheath structure.

[0011] A traction motor is fixedly connected to an outer wall of one side of the traction frame, and the output end of the traction motor is connected to the No. 1 traction shaft through a coupling. The end of the No. 1 traction shaft away from the traction motor passes through the traction frame and is connected to the No. 1 gear, and one end of the No. 2 traction shaft passes through the traction frame and is connected to the No. 2 gear.

[0012] By adopting the above technical solution, the traction motor drives the No. 1 traction shaft to rotate, and the rotation of the No. 1 traction shaft drives the traction wheel on its outer wall to rotate, thereby achieving the traction effect on the optical cable. At the same time, the rotation of the No. 1 traction shaft drives the No. 1 gear to rotate.

[0013] One side outer wall of the traction frame is connected to a linkage shaft through a bearing, and one side outer wall of the linkage shaft is fixedly connected to the third gear. One side of the third gear is provided with a fourth gear. The first gear and the third gear are connected by a transmission belt, and the second gear is meshed with the fourth gear.

[0014] By adopting the above technical solution, after the No. 1 gear rotates, it drives the No. 3 gear to rotate through the transmission belt. The rotation of the No. 3 gear drives the linkage shaft to rotate synchronously. The rotation of the linkage shaft drives the No. 4 gear to rotate synchronously. The rotation of the No. 4 gear drives the No. 2 gear to rotate in the opposite direction, thereby driving the No. 2 traction shaft to rotate. At the same time, the rotation direction of the No. 2 traction shaft is opposite to that of the No. 1 traction shaft, so that the two sets of traction wheels rotate in opposite directions. The optical cables are staggered around the surfaces of the two sets of traction wheels to achieve synchronous operation of the two traction wheels to improve traction, which is suitable for long-distance laying.

[0015] The side of the traction frame away from the optical cable storage warehouse is fixedly connected to a linkage frame, and the end of the linkage frame away from the traction frame is movably connected to a rotating ring through a bearing, and the outer wall of the rotating ring is fixedly connected to a bevel gear ring, and the outer wall of one side of the linkage frame is connected to a linkage rod through a bearing, and one end of the linkage rod is connected to a No. 1 bevel gear, and the No. 1 bevel gear is meshed with the bevel gear ring.

[0016] By adopting the above technical solution, the linkage frame plays a connecting role, the rotating ring can rotate at one end of the linkage frame, thereby driving the bevel gear ring to rotate synchronously, and the linkage rod can rotate on one side of the linkage frame.

[0017] The end of the second traction shaft away from the second gear passes through the traction frame and is connected to the second bevel gear. The end of the linkage rod away from the first bevel gear is connected to the third bevel gear. The third bevel gear is meshed with the second bevel gear.

[0018] By adopting the above technical solution, the No. 2 bevel gear engages with the No. 3 bevel gear to transmit the power of the No. 2 traction shaft to the linkage rod, realizing 90° power steering. The No. 1 bevel gear at the end of the linkage rod engages with the bevel gear ring to drive the rotation to revolve horizontally around the axis of the optical cable.

[0019] The inner wall of the rotating ring is equidistantly arranged with threaded barrels penetrating through it, and the threaded barrels are connected to the rotating ring through bearings. The inner wall of the threaded barrel is threadedly connected with screw rods. One end of the screw rod close to the center of the rotating ring is connected with an arc-shaped plate, and the surface of the arc-shaped plate is connected with bristles. A pressure sensor is arranged at the center of the arc-shaped plate. Limit holes are arranged on both inner walls of the rotating ring on both sides of the threaded barrel. Limit rods are connected to both outer walls of the arc-shaped plate, and the limit rods are embedded in the limit holes.

[0020] By adopting the above technical solution, the limit holes are oblong holes, allowing the limit rods to slide along the axial direction of the holes, ensuring that the screw rods only move linearly without yaw and at the same time restricting the movement trajectory of the arc-shaped plate, so that the bristles always point vertically to the axis of the optical cable. The rotating ring rotates horizontally around the axis of the optical cable, thereby driving the threaded barrels, screw rods and arc-shaped plates to rotate. The rotation of the arc-shaped plate drives the bristles to rotate along the surface of the optical cable, thereby realizing the cleaning of the surface of the optical cable, removing impurities in real time, reducing the surface friction coefficient, reducing the risk of sheath scratching, maintaining the cleanliness of the surface of the optical cable, avoiding local pressure concentration, ensuring that the attenuation value is lower than 0.36 dB / km, and the tension of the optical cable during traction can be detected through the pressure sensor, so as to facilitate subsequent adjustment.

[0021] A driving gear is fixedly connected to the outer wall of the threaded barrel. The outer wall of the rotating ring is movably connected with an adjusting ring through a bearing. A tooth groove is arranged on one outer wall of the adjusting ring. The driving gear meshes with the tooth groove. A limit block is fixedly connected to one outer wall of the rotating ring. A spring is fixedly connected to one outer wall of the limit block. One end of the spring is fixedly connected with a limit tooth. The limit tooth meshes with the tooth groove. A controller is arranged on one side of the top of the base, and driving wheels are arranged in an array at the bottom of the base.

[0022] By adopting the above technical solution, when adjustment is needed, the limit tooth is pushed to separate it from the tooth groove, and the adjusting ring is manually rotated. The tooth groove on its outer wall meshes with the driving gear, thereby driving the threaded barrel to rotate self, and the rotation of the threaded barrel drives the threaded barrel to rotate, thereby driving the screw rod to move axially. The axial movement of the screw rod pushes the arc-shaped plate to expand and contract radially, thereby realizing the adjustment of the bristles to facilitate adaptation to optical cables of different diameters. After the adjustment is in place, the spring pushes the limit tooth to automatically snap into the tooth groove to form a mechanical interlock to prevent the adjusting ring from accidentally rotating. The controller plays a control role, and the driving wheels can assist the device to move and lay the optical cable.

[0023] The laying method includes the following steps: Step 1: The optical cable take-up reel is sleeved on the rotating shaft, placed on the movable frame, and passes through the middle parts of two groups of limit frames. The adjusting knob is rotated to drive the bidirectional threaded rod to rotate, thereby driving the two threaded moving blocks to move synchronously towards each other, driving the limit frames to contract or expand to limit optical cables of different diameters, and the auxiliary balls reduce the friction when the optical cable is released; Step 2: Pass the optical cable through the limit frame around the two sets of traction wheel surfaces in sequence, and drive the traction motor to drive the No. 1 traction shaft to rotate. The rotation of the No. 1 traction shaft drives the traction wheel on its outer wall to rotate, thereby achieving the traction effect on the optical cable; Step 3: The second traction shaft and the first traction shaft rotate in opposite directions through the linkage of the gear set, so that the two sets of traction wheels rotate in opposite directions. The optical cables are staggered around the surfaces of the two sets of traction wheels so that the two traction wheels work synchronously to improve traction. The buffer pads on the traction wheel surface provide flexible clamping to prevent the cable sheath from being crushed; Step 4: The No. 2 traction shaft rotates while driving the No. 2 bevel gear to rotate, thereby driving the No. 3 bevel gear and the linkage rod to rotate. The rotation of the linkage rod drives the No. 1 bevel gear to rotate, thereby driving the bevel gear ring and the rotating ring to rotate. The rotating ring rotates, and the bristles on the surface of the arc plate revolve with the rotating ring 26, brushing the surface of the optical cable in a circumferential direction; Step 5: The pressure sensor monitors the bristle pressure in real time and transmits the signal to the controller, which then adjusts the speed of the traction motor to maintain constant tension. Step 6: After laying, turn off the traction motor and check the status of the optical cable.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. The two sets of limit frames are arranged relative to each other so that the inner wall cooperates to form an arc shape, so as to guide the optical cable. At the same time, during the guiding process, the movable block can move to a certain extent according to the different pulling positions of the optical cable, reducing the angle of the optical cable access and avoiding the entanglement of the optical cable during the pulling process. This improves the laying efficiency of the communication optical cable in complex environments and reduces the damage of the optical cable during the laying process. 2. The rotating ring rotates along with the No. 2 traction shaft, and the rotation revolves horizontally around the axis of the optical cable, thereby driving the threaded barrel, screw and curved plate to rotate. The rotation of the curved plate drives the bristles to rotate along the surface of the optical cable, thereby cleaning the surface of the optical cable, removing impurities in real time, reducing the surface friction coefficient, reducing the risk of sheath scratches, and keeping the surface of the optical cable clean.

Detailed implementation manners

[0026] The following Figure 1 - attached Figure 8 , further elaborates on the present application in detail.

[0027] Embodiment 1: A laying device for communication optical cables, comprising a base 1. On one side of the top of the base 1, an optical cable storage bin 2 is fixedly connected. In the middle inner wall of the optical cable storage bin 2, a movable frame 3 is fixedly connected. At the top of the movable frame 3, a rotating shaft 4 is connected through a bearing. On the middle outer wall of the rotating shaft 4, an optical cable winding drum 5 is sleeved. On one side of the optical cable winding drum 5, a sliding rod 6 is provided. The sliding rod 6 is fixedly connected to one side inner wall of the optical cable storage bin 2. On the outer wall of the sliding rod 6, a movable block 7 is slidably connected. On the top outer wall of the movable block 7, a connecting seat 8 is fixedly connected. On the top outer wall of the connecting seat 8, a limiting groove 9 is provided. In the middle of the limiting groove 9, a bidirectional threaded rod 10 is connected through a bearing. On both sides of the bidirectional threaded rod 10 with opposite threads, threaded moving blocks 11 are threadedly connected. On the top outer walls of the two threaded moving blocks 11, limiting frames 12 are fixedly connected. The two limiting frames 12 are arranged oppositely. Among them, the base 1 plays a supporting role. The optical cable winding drum 5 is sleeved on the rotating shaft 4 and placed on the movable frame 3. The bidirectional threaded rod 10 can rotate in the limiting groove 9. At the same time, the threaded moving block 11 is slidably connected with the limiting groove 9 to prevent the threaded moving block 11 from rotating. The connecting seat 8 plays a connecting role. The two limiting frames 12 are arranged oppositely so that their inner walls cooperate to form an arc shape to facilitate guiding the optical cable. At the same time, during the guiding process, the movable block 7 can move to a certain extent following different traction positions of the optical cable, reducing the access angle of the optical cable and avoiding winding of the optical cable during the traction process.

[0028] On one side outer wall of the connecting seat 8, an adjusting knob 13 is provided. The adjusting end of the adjusting knob 13 is connected to the bidirectional threaded rod 10. At the bottom outer wall of the limiting frame 12 close to the adjusting knob 13, a telescopic strip 15 is fixedly connected. On the bottom outer wall of the opposite limiting frame 12, a telescopic groove 16 is provided. The telescopic strip 15 and the telescopic groove 16 are arranged correspondingly, and one end of the telescopic strip 15 is embedded in the telescopic groove 16. On the top outer wall of the telescopic strip 15 and the inner walls of the two limiting frames 12, auxiliary balls 14 are embedded. By manually rotating the adjusting knob 13, the bidirectional threaded rod 10 can be driven to rotate synchronously. The opposite threads of the bidirectional threaded rod 10 drive the two threaded moving blocks 11 to move towards each other along the limiting groove 9. The two limiting frames 12 move inwards synchronously with the threaded moving blocks 11 and gradually clamp both sides of the optical cable winding drum 5. When the distance between the limiting frames 12 is reduced to a certain value, the telescopic strip 15 is inserted into the telescopic groove 16 of the opposite limiting frame 12 to form a rigid connection. When the optical cable is released, the surface of the optical cable winding drum 5 rolls in contact with the auxiliary balls 14 on the inner wall of the limiting frame 12, reducing the frictional resistance.

[0029] A traction module 17 is provided on one side of the optical cable storage bin 2. The traction module 17 includes a traction frame 171, a No. 1 traction shaft 172, a No. 2 traction shaft 173, a traction wheel 174 and a traction motor 175. The traction frame 171 is provided on one side of the optical cable storage bin 2. The top side of the traction frame 171 is connected to the No. 1 traction shaft 172 through a bearing. A No. 2 traction shaft 173 is provided on one side of the No. 1 traction shaft 172. The No. 2 traction shaft 173 is also directly connected to the traction frame 171 through a bearing. The No. 1 traction shaft 172 and the No. 2 traction shaft 173 are connected to each other. The middle outer wall is fixedly connected with a traction wheel 174. The two sets of traction wheels 174 are in the same straight line, and the surface of the traction wheel 174 is provided with a buffer pad 18. The two sets of traction wheels 174 are respectively fixed to the independent No. 1 traction shaft 172 and No. 2 traction shaft 173, and are in the same straight line. The optical cable passes through between the two wheels to form a symmetrical clamping traction. The surface of the traction wheel 174 is fully covered with the buffer pad 18, which converts the rigid contact into elastic pressure, realizes pressure dispersion, reduces the contact surface pressure, and reduces the indentation rate of the optical cable surface, providing protection of the integrity of the sheath structure.

[0030] A traction motor 175 is fixedly connected to the outer wall of one side of the traction frame 171, and the output end of the traction motor 175 is connected to the No. 1 traction shaft 172 through a coupling. The end of the No. 1 traction shaft 172 away from the traction motor 175 passes through the traction frame 171 and is connected to the No. 1 gear 19, and one end of the No. 2 traction shaft 173 passes through the traction frame 171 and is connected to the No. 2 gear 20. The traction motor 175 drives the No. 1 traction shaft 172 to rotate, and the rotation of the No. 1 traction shaft 172 drives the traction wheel 174 on its outer wall to rotate, thereby realizing the traction effect on the optical cable. At the same time, the rotation of the No. 1 traction shaft 172 drives the No. 1 gear 19 to rotate.

[0031] The outer wall of one side of the traction frame 171 is connected to the linkage shaft 21 through a bearing, and the outer wall of one side of the linkage shaft 21 is fixedly connected to the third gear 22. A fourth gear 23 is provided on one side of the third gear 22. The first gear 19 and the third gear 22 are connected by a transmission toothed belt 24, and the second gear 20 is meshed with the fourth gear 23. The rotation of the first gear 19 then drives the third gear 22 to rotate through the transmission toothed belt 24. The rotation of the third gear 22 drives the linkage shaft 21 to rotate synchronously. The rotation of the linkage shaft 21 drives the fourth gear 23 to rotate synchronously. The rotation of the fourth gear 23 drives the second gear 20 to rotate in the opposite direction, thereby driving the second traction shaft 173 to rotate. At the same time, the rotation directions of the second traction shaft 173 and the first traction shaft 172 are opposite, so that the two sets of traction wheels 174 rotate in opposite directions. The optical cables are staggered around the surfaces of the two sets of traction wheels 174 to achieve synchronous operation of the two traction wheels 174 to improve traction, which is suitable for long-distance laying.

[0032] On one side of the traction frame 171 away from the optical cable storage bin 2, a linkage frame 25 is fixedly connected. One end of the linkage frame 25 away from the traction frame 171 is movably connected with a rotating ring 26 through a bearing. An external wall of the rotating ring 26 is fixedly connected with a bevel gear ring 27. One side external wall of the linkage frame 25 is connected with a linkage rod 28 through a bearing. One end of the linkage rod 28 is connected with a first bevel gear 29. The first bevel gear 29 meshes with the bevel gear ring 27. The linkage frame 25 plays a connecting role. The rotating ring 26 can rotate at one end of the linkage frame 25, thereby driving the bevel gear ring 27 to rotate synchronously. The linkage rod 28 can rotate on one side of the linkage frame 25.

[0033] One end of the second traction shaft 173 away from the second gear 20 passes through the traction frame 171 and is connected with a second bevel gear 30. One end of the linkage rod 28 away from the first bevel gear 29 is connected with a third bevel gear 31. The third bevel gear 31 meshes with the second bevel gear 30. The rotation of the second traction shaft 173 drives the second bevel gear 30 at the end to rotate synchronously. The second bevel gear 30 meshes with the third bevel gear 31, thereby transmitting the power of the second traction shaft 173 to the linkage rod 28 to achieve a 90° power steering. The first bevel gear 29 at the end of the linkage rod 28 meshes with the bevel gear ring 27, thereby driving the rotating ring 26 to horizontally revolve around the optical cable axis.

[0034] Threaded cylinders 33 are arranged at equal intervals on the inner wall of the rotating ring 26 and penetrate through. The threaded cylinders 33 are connected with the rotating ring 26 through bearings. A screw rod 34 is threadedly connected to the inner wall of the threaded cylinder 33. One end of the screw rod 34 close to the center of the rotating ring 26 is connected with an arc-shaped plate 35. A brush hair 36 is connected to the surface of the arc-shaped plate 35. A pressure sensor 32 is arranged at the center of the arc-shaped plate 35. Limit holes 37 are arranged on both inner walls of the rotating ring 26 on both sides of the threaded cylinder 33. Limit rods 38 are connected to both outer walls of the arc-shaped plate 35. The limit rods 38 are embedded in the limit holes 37. The limit holes 37 are oblong holes, allowing the limit rods 38 to slide along the axial direction of the holes, ensuring that the screw rod 34 only moves linearly without yaw and restricting the movement track of the arc-shaped plate 35, so that the brush hair 36 always points vertically to the optical cable axis. The horizontal revolution of the rotating ring 26 around the optical cable axis drives the threaded cylinder 33, the screw rod 34 and the arc-shaped plate 35 to rotate. The rotation of the arc-shaped plate 35 drives the brush hair 36 to rotate along the surface of the optical cable, thereby realizing the cleaning of the surface of the optical cable, removing impurities in real time, reducing the surface friction coefficient, reducing the risk of sheath scratching, maintaining the cleanliness of the optical cable surface, avoiding local pressure concentration, ensuring that the attenuation value is lower than 0.36 dB / km, and the tension of the optical cable during traction can be detected through the pressure sensor 32, so as to facilitate subsequent adjustment.

[0035] The outer wall of the threaded cylinder 33 is fixedly connected to a driving gear 39, and the outer wall of the rotating ring 26 is movably connected to an adjusting ring 40 through a bearing. A tooth groove 41 is provided on one side of the outer wall of the adjusting ring 40, and the driving gear 39 is engaged with the tooth groove 41. The outer wall of one side of the rotating ring 26 is fixedly connected to a limiting block 42, and a spring 43 is fixedly connected to one side of the outer wall of the limiting block 42. One end of the spring 43 is fixedly connected to a limiting tooth 44, and the limiting tooth 44 is engaged with the tooth groove 41. A controller 45 is provided on the top side of the base 1, and a driving wheel 46 is arranged at the bottom of the base 1. When adjustment is required, the limiting tooth 44 is pushed 4 is separated from the tooth groove 41, and the adjusting ring 40 is manually rotated. The tooth groove 41 on its outer wall engages with the driving gear 39, thereby driving the threaded barrel 33 to rotate. The rotation of the threaded barrel 33 drives the threaded barrel 33 to rotate, thereby driving the screw 34 to move axially. The axial movement of the screw 34 pushes the arc plate 35 to expand and contract radially, thereby achieving the adjustment of the bristles 36 to adapt to optical cables of different diameters. After the adjustment is in place, the spring 43 pushes the limiting teeth 44 to automatically engage the tooth groove 41, forming a mechanical interlock to prevent the adjusting ring 40 from rotating accidentally. The controller 45 plays a controlling role, and the driving wheel 46 can assist the device in moving and laying optical cables.

[0036] The laying method includes the following steps: Step 1: Insert the optical cable reel 5 into the rotating shaft 4, place it on the movable frame 3, and pass it through the middle of the two sets of limit frames 12. Rotate the adjustment knob 13 to drive the bidirectional threaded rod 10 to rotate, thereby driving the two sets of threaded moving blocks 11 to move synchronously towards each other, driving the limit frames 12 to contract or expand to limit optical cables of different diameters. The auxiliary ball 14 reduces friction when the optical cable is released; Step 2: The optical cable passing through the limit frame 12 is passed around the surfaces of the two sets of traction wheels 174 in sequence, and the traction motor 175 drives the No. 1 traction shaft 172 to rotate. The rotation of the No. 1 traction shaft 172 drives the traction wheels 174 on its outer wall to rotate, thereby achieving the traction effect on the optical cable; Step 3: The second traction shaft 173 and the first traction shaft 172 rotate in opposite directions through the linkage of the gear set, so that the two sets of traction wheels 174 rotate in opposite directions. The optical cables are staggered around the surfaces of the two sets of traction wheels 174 so that the two traction wheels 174 work synchronously to improve traction. The buffer pads 18 on the surfaces of the traction wheels 174 provide flexible clamping to prevent the cable sheath from being crushed. Step 4: The second traction shaft 173 rotates, driving the second bevel gear 30 to rotate, thereby driving the third bevel gear 31 and the linkage rod 28 to rotate. The linkage rod 28 rotates, driving the first bevel gear 29 to rotate, thereby driving the bevel gear ring 27 and the rotating ring 26 to rotate. The rotating ring 26 rotates, and the bristles 36 on the surface of the arc plate 35 revolve with the rotating ring 26, brushing the surface of the optical cable in a circumferential direction. Step 5: The pressure sensor 32 monitors the pressure of the bristles 36 in real time, and transmits the signal to the controller 45, which controls and adjusts the speed of the traction motor 175 to maintain constant tension; Step 6: After the laying is completed, turn off the traction motor 175 and check the status of the optical cable.

[0037] The implementation principle of the embodiment of the present application is as follows: first, the cable reel 5 is inserted into the rotating shaft 4 and placed on the movable frame 3, and the bidirectional threaded rod 10 can rotate in the limiting groove 9, and at the same time, the threaded moving block 11 is slidably connected with the limiting groove 9 to prevent the threaded moving block 11 from rotating, and the connecting seat 8 plays a connecting role. The two sets of limiting frames 12 are relatively arranged so that the inner walls cooperate to form an arc shape, so as to guide the optical cable. At the same time, during the guiding process, the movable block 7 can move to a certain extent following the different traction positions of the optical cable, reducing the angle of the optical cable access and avoiding the entanglement of the optical cable during the traction process. By manually rotating the adjustment knob 13 The two-way threaded rod 10 can be driven to rotate synchronously. The opposite threads of the two-way threaded rod 10 drive the two sets of threaded moving blocks 11 to move toward each other along the limit groove 9. The two sets of limit frames 12 move inward synchronously with the threaded moving blocks 11, gradually clamping the two sides of the cable winding drum 5. When the spacing between the limit frames 12 is reduced to a certain value, the telescopic strip 15 is inserted into the telescopic groove 16 of the limit frame 12 on the opposite side to form a rigid connection. When the optical cable is released, the surface of the cable winding drum 5 rolls with the auxiliary ball 14 on the inner wall of the limit frame 12 to reduce friction resistance. The traction motor 175 drives the No. 1 traction shaft 172 to rotate. The rotation of the No. 1 traction shaft 172 drives the traction wheel 174 on its outer wall to rotate, thereby realizing the traction of the optical cable. The No. 2 traction shaft 173 The rotation direction is opposite to that of the No. 1 traction shaft 172 through the linkage of the gear set, so that the two sets of traction wheels 174 rotate in opposite directions. The optical cables are staggered around the surfaces of the two sets of traction wheels 174 so that the two traction wheels 174 can work synchronously to improve traction. The buffer pads 18 on the surfaces of the traction wheels 174 provide flexible clamping to prevent the optical cable sheath from being crushed. The rotating ring 26 can rotate with the No. 2 traction shaft 173. The rotating ring 26 revolves horizontally around the axis of the optical cable, thereby driving the threaded barrel 33, the screw 34 and the arc plate 35 to rotate. The rotation of the arc plate 35 drives the bristles 36 to rotate along the surface of the optical cable, thereby cleaning the surface of the optical cable, removing impurities in real time, reducing the surface friction coefficient, reducing the risk of sheath scratches, and keeping the surface of the optical cable clean.
