Description

Technical Field

[0001] This application relates to the field of optical fiber laying technology, and in particular to an adaptive optical fiber cable laying device. Background Technology

[0002] Optical fiber is short for optical waveguide fiber. It is a type of fiber made of glass or plastic that can be used as a light transmission tool. The fine optical fiber is encapsulated in a plastic sheath, which allows it to bend without breaking. Typically, the transmitting device at one end of the optical fiber uses a light-emitting diode or a laser beam to transmit light pulses to the optical fiber, while the receiving device at the other end of the optical fiber uses a photosensitive element to detect the pulses.

[0003] An existing patent (publication number: CN222556175U) discloses an optical fiber cable laying rack. A support frame is fixedly connected to the upper end of the base. A rotating disk is rotatably connected to the inside of the left side wall of the support frame. A disassembly screw is spirally connected to the inner side of the rotating disk. Mounting plates are rotatably connected to the right end of the disassembly screw and the inner side of the right end wall of the support frame. A winding roller is slidably connected to the inner side of the mounting plate. This invention utilizes the rotation of the first turntable to enable the worm gear to rotate, thereby allowing the mounting plate on the right side to rotate the winding roller via a limiting clamp, facilitating cable laying control and preventing the winding roller from loosening. Furthermore, the rotation of the second turntable allows the disassembly screw to rotate, enabling the mounting plate on the left side to move left and right, allowing for quick disassembly and assembly of the winding roller. This facilitates rapid replacement of the winding roller used for winding optical fibers, improving the ease of fiber optic cable installation and removal on the laying rack.

[0004] In the aforementioned comparative documents, the fiber optic cable laying frame controls the rotation of the winding roller to lay the cable through a transmission structure of "first turntable → worm → worm wheel". However, the worm wheel transmission requires continuous rotation of the first turntable, which is cumbersome to operate, has low laying efficiency, and the transmission speed is limited by the meshing ratio of the worm wheel, making it difficult to achieve rapid adjustment. In particular, the response is slow when an emergency stop or rapid laying is required. Utility Model Content

[0005] The purpose of this application is to provide an adaptive cable laying device for optical fibers and cables, which facilitates cable laying and solves the problem of low laying efficiency caused by worm gear transmission.

[0006] The adaptive fiber optic cable laying device provided in this application adopts the following technical solution: The adaptive fiber optic cable laying device includes a base plate, a mounting assembly, a driving assembly, an adaptive assembly, and a guide buffer assembly. The mounting assembly includes a first mounting plate and a second mounting plate. A groove is formed on the upper surface of the base plate. A bidirectional lead screw is rotatably sleeved on the inner wall of the groove. The bottom ends of the first mounting plate and the second mounting plate are respectively threaded to the two ends of the bidirectional lead screw. A rotatable chuck is installed on the inner wall of both the first mounting plate and the second mounting plate. A laying roller is provided above the base plate. A connecting plate is fixedly connected to both ends of the laying roller. The connecting plate is adapted to the chuck.

[0007] The drive assembly includes a drive box fixedly connected to the outside of the first mounting plate. A rotating rod is rotatably connected to the inner wall of the drive box. One end of the rotating rod is fixedly connected to the rotating shaft end of the corresponding chuck. A ratchet is fixedly connected to the outer surface of the rotating rod. A rotatable pawl is installed on the inner wall of the drive box. The pawl meshes with the ratchet. A return spring is fixedly connected to the inner top wall of the drive box. The bottom end of the return spring is fixedly connected to the upper surface of the pawl.

[0008] By adopting the above technical solution, the sliding groove and bidirectional screw of the base plate and the mounting component cooperate to enable the first mounting plate and the second mounting plate to move synchronously in opposite directions, driving the chuck to quickly clamp or release the feeding roller, solving the problem of cumbersome disassembly and assembly of the feeding roller in the prior art, and improving the convenience of fiber optic cable replacement. The ratchet and pawl in the drive box engage, and the pawl can be turned by the crank handle to drive the rotating rod to rotate intermittently. Compared with worm gear transmission, it does not require continuous rotation, realizing the efficient operation of "single turn - quantitative feeding" and solving the problem of low feeding efficiency.

[0009] Preferably, two limiting plates are fixedly connected to the outer surface of the bidirectional lead screw, and a servo motor is fixedly connected to one side of the base plate. The output shaft end of the servo motor is fixedly connected to the rotating shaft end of the bidirectional lead screw.

[0010] By adopting the above technical solution, the servo motor drives the bidirectional lead screw to rotate, and the limit plate prevents the first and second mounting plates from moving excessively, thereby realizing the automated and precise adjustment of the installation position of the pay-off roller, reducing manual operation steps and improving the ease of use of the equipment.

[0011] Preferably, a miniature bracket is fixedly connected to the upper surface of the base plate, and two guide rails are installed on the inner wall of the miniature bracket. The bottom of the first mounting plate and the second mounting plate are slidably sleeved on the outer surface of the two guide rails, respectively.

[0012] By adopting the above technical solution, the guide rail on the miniature bracket forms a sliding limit on the first mounting plate and the second mounting plate, ensuring that the chuck maintains coaxiality during movement, avoiding tilting of the wire feeding roller installation, and improving the stability of equipment operation.

[0013] Preferably, a crank is fixedly connected to the shaft end of the rotating rod, a reserved slot is provided on one side of the drive box, and a paddle is fixedly connected to the outer surface of the pawl, with the paddle disposed inside the reserved slot.

[0014] By adopting the above technical solution, the crank handle is directly fixed to the rotating rod, and the pawl can be quickly reset by the paddle in the reserved slot, realizing the rapid switching between line feeding and stopping, and solving the problem of slow emergency response in the existing technology.

[0015] Preferably, the adaptive component includes a one-way screw threaded to one side of the first mounting plate and the second mounting plate, each one-way screw having a metal friction damping plate rotatably sleeved at its output end, and each one-way screw having a knob fixedly connected to its shaft end.

[0016] By adopting the above technical solution, the contact pressure between the metal friction damping plate and the chuck is adjusted by the unidirectional screw. The damping force can be preset by rotating the knob. When the speed of the pay-off roller is too fast, the friction force of the metal friction damping plate automatically increases, suppressing inertial rotation and realizing adaptive pay-off control.

[0017] Preferably, two limiting rods are slidably sleeved on one side of both the first mounting plate and the second mounting plate, and the four limiting rods are respectively fixedly connected to the outer surface of the two metal friction damping plates, and the inner side of the metal friction damping plates is adapted to the outer surface of the chuck.

[0018] By adopting the above technical solution, the limiting rod is fixed to the metal friction damping plate, ensuring that the metal friction damping plate remains parallel and in contact with the chuck when it moves, avoiding uneven damping force caused by tilting, and improving the reliability of adaptive adjustment.

[0019] Preferably, the guide buffer assembly includes two columns fixedly connected to the upper surface of the base plate, each column having two guide grooves on its inner side, each guide groove having a guide block slidably fitted on its inner wall, and two guide rollers being provided above the base plate.

[0020] By adopting the above technical solution, the four guide blocks can slide in the four guide grooves respectively, which facilitates the subsequent adjustment of the guide rollers.

[0021] Preferably, the two ends of the two guide rollers are respectively rotatably sleeved in the inner wall of the four guide blocks, and a telescopic spring is fixedly connected to the outer surface of each guide block. A guide post is fixedly connected to the inner wall of each guide groove, and the guide block is slidably sleeved on the outer surface of the guide post.

[0022] By adopting the above technical solution, the guide block inside the column is connected to the guide column through a telescopic spring, which drives the guide roller to float and buffer, absorb the instantaneous tension when the optical fiber cable is laid, prevent the cable from shaking and knotting, and protect the optical fiber coating from damage.

[0023] In summary, this application includes at least one of the following beneficial technical effects: This adaptive fiber optic cable laying device replaces the traditional worm gear rotation mode with ratchet and pawl meshing transmission, significantly improving laying efficiency. A servo motor drives a bidirectional lead screw, causing the first and second mounting plates to move synchronously, enabling automated and rapid assembly and disassembly of the laying roller. A unidirectional lead screw adjusts the contact pressure between the metal friction damping plate and the chuck; when the laying roller rotates too fast, the damping force automatically increases to suppress inertial rotation, achieving adaptive laying control. Through the cooperation of the guide block inside the column and the telescopic spring, the guide roller floats and buffers, absorbing the instantaneous tension during cable laying, preventing shaking and knotting, and protecting the fiber coating. The overall structure requires no complex electrical control system, achieving efficient, convenient, and stable fiber optic laying operations. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0027] Example 1: Adaptive fiber optic cable laying device, refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 The system includes a base plate 1, a mounting assembly 2, a drive assembly 3, an adaptive assembly 4, and a guide buffer assembly 5. The mounting assembly 2 includes a first mounting plate 201 and a second mounting plate 202. A groove 203 is formed on the upper surface of the base plate 1, and a bidirectional lead screw 204 is rotatably sleeved on the inner wall of the groove 203. The bottom ends of the first mounting plate 201 and the second mounting plate 202 are respectively threaded to the two ends of the bidirectional lead screw 204. Rotatable chucks 209 are installed on the inner walls of both the first mounting plate 201 and the second mounting plate 202. A wire feeding roller 6 is provided above the base plate 1, and connecting discs 7 are fixedly connected to both ends of the wire feeding roller 6. The connecting discs 7 are adapted to the chucks 209. Two limit plates 205 are fixedly connected to the outer surface of the bidirectional lead screw 204. A servo motor 206 is fixedly connected to one side of the base plate 1. The servo motor 206 outputs... The output shaft end is fixedly connected to the rotating shaft end of the bidirectional lead screw 204. The servo motor 206 drives the bidirectional lead screw 204 to rotate. With the help of the limit plate 205, the first mounting plate 201 and the second mounting plate 202 are prevented from moving excessively, so as to realize the automated and precise adjustment of the installation position of the wire feeding roller 6, reduce manual operation steps, and improve the convenience of equipment use. A miniature bracket 207 is fixedly connected to the upper surface of the base plate 1. Two guide rails 208 are installed on the inner wall of the miniature bracket 207. The bottom of the first mounting plate 201 and the second mounting plate 202 are respectively slidably sleeved on the outer surface of the two guide rails 208. The guide rails 208 on the miniature bracket 207 form a sliding limit on the first mounting plate 201 and the second mounting plate 202, ensuring that the chuck 209 maintains coaxiality during movement, avoiding the wire feeding roller 6 from tilting during installation, and improving the stability of equipment operation.

[0028] Reference Figure 3 , Figure 4 and Figure 5The drive assembly 3 includes a drive box 301 fixedly connected to the outside of the first mounting plate 201. A rotating rod 302 is rotatably connected to the inner wall of the drive box 301. One end of the rotating rod 302 is fixedly connected to the rotating shaft end of the corresponding chuck 209. A ratchet 303 is fixedly connected to the outer surface of the rotating rod 302. A rotatable pawl 304 is installed on the inner wall of the drive box 301. The pawl 304 meshes with the ratchet 303. A return spring 305 is fixedly connected to the inner top wall of the drive box 301. The bottom of the return spring 305... The end is fixedly connected to the upper surface of the pawl 304, and the shaft end of the rotating rod 302 is fixedly connected to the crank handle 306. A reserved slot 307 is provided on one side of the drive box 301. A paddle 308 is fixedly connected to the outer surface of the pawl 304. The paddle 308 is set inside the reserved slot 307. The crank handle 306 is directly fixed to the rotating rod 302. With the paddle 308 in the reserved slot 307, the pawl 304 can be quickly moved to reset, realizing the rapid switching between line feeding and stopping, and solving the problem of slow emergency response in the prior art.

[0029] Example 2: Adaptive fiber optic cable laying device, refer to Figure 1 , Figure 4 and Figure 6 Based on the same concept as Embodiment 1 above, this embodiment proposes an adaptive component 4 including a one-way screw 401 threadedly connected to one side of the first mounting plate 201 and the second mounting plate 202. Each one-way screw 401 has a metal friction damping plate 402 rotatably sleeved at its output end. Each one-way screw 401 has a knob 404 fixedly connected to its shaft end. The one-way screw 401 adjusts the contact pressure between the metal friction damping plate 402 and the chuck 209. Rotating the knob 404 presets the damping force. When the speed of the pay-off roller 6 is too fast, the friction force of the metal friction damping plate 402 naturally decreases. Increased motion suppresses inertial rotation and enables adaptive wire feeding control. Two limit rods 403 are slidably sleeved on one side of the first mounting plate 201 and the second mounting plate 202. The four limit rods 403 are respectively fixedly connected to the outer surface of the two metal friction damping plates 402, and the inner side of the metal friction damping plates 402 is adapted to the outer surface of the chuck 209. The limit rods 403 are fixed to the metal friction damping plates 402 to ensure that the metal friction damping plates 402 remain parallel and in contact with the chuck 209 when they move, avoiding uneven damping force caused by tilting and improving the reliability of adaptive adjustment.

[0030] Reference Figure 1 , Figure 2 and Figure 3The guide buffer assembly 5 includes two columns 501 fixedly connected to the upper surface of the base plate 1. Each column 501 has two guide grooves 502 on its inner side. A guide block 503 is slidably fitted on the inner wall of each guide groove 502. Two guide rollers 506 are provided above the base plate 1. The four guide blocks 503 can slide in the four guide grooves 502 respectively, which facilitates the subsequent adjustment of the guide rollers 506. The two ends of the two guide rollers 506 are respectively rotatably fitted in the inner wall of the four guide blocks 503. A telescopic spring 504 is fixedly connected to the outer surface of each guide block 503. A guide post 505 is fixedly connected to the inner wall of each guide groove 502. The guide block 503 is slidably fitted on the outer surface of the guide post 505. The guide block 503 in the column 501 is connected to the guide post 505 through the telescopic spring 504, which drives the guide roller 506 to float and buffer, absorb the instantaneous tension when the optical fiber cable is laid, prevent the cable from shaking and knotting, and protect the optical fiber coating from damage.

[0031] The implementation principle of this application embodiment is as follows: First, the servo motor 206 drives the bidirectional lead screw 204 to rotate, causing the first mounting plate 201 and the second mounting plate 202 to move away from each other along the guide rail 208 within the slide groove 203. After the two chucks 209 are released, the connecting discs 7 at both ends of the pay-off roller 6 are inserted into the chucks 209. Then, the servo motor 206 is started in reverse to make the two chucks 209 clamp the pay-off roller 6. The limiting piece 205 can prevent the first mounting plate 201 and the second mounting plate 202 from moving excessively. When driving the pay-off, the crank 306 is turned to drive the rotating rod 302 to rotate. The ratchet 303 and the pawl 304 engage to make the corresponding chuck 209 drive the pay-off roller 6 to rotate intermittently. The reset spring 305 ensures that the pawl 304 automatically resets, realizing "single lever-quantitative pay-off". If an emergency stop is required, the pay-off roller 6 can be quickly locked by tightly gripping the lever 308 to stop the lever 308 from moving. During adaptive damping control, rotating the knob 404 drives the unidirectional lead screw 401 to adjust the contact pressure between the metal friction damping plate 402 and the chuck 209. When the speed of the pay-off roller 6 is too fast, the friction of the metal friction damping plate 402 automatically increases to suppress inertial rotation. The limit rod 403 ensures that the metal friction damping plate 402 is in parallel contact to distribute force evenly. During the fiber optic cable laying process, when the cable passes through the guide roller 506, the telescopic spring 504 pushes the guide block 503 to slide in the guide groove 502, causing the guide roller 506 to float and buffer, absorbing instantaneous tension fluctuations. The guide column 505 ensures the stable movement of the guide roller 506, preventing the cable from shaking and knotting, thereby achieving efficient, stable and adaptive fiber optic cable laying operation.
