Description

Technical Field

[0001] This invention relates to the field of cable winding technology, and in particular to an optical cable winch. Background Technology

[0002] In the manufacturing, storage and use of linear materials such as wires, cables, optical cables, and ropes, it is usually necessary to regularly wind the cables onto take-up rollers (or reels, drums) to facilitate transportation, storage and subsequent cable laying operations.

[0003] In cable or fiber optic communication operations, it is sometimes necessary to adjust the cable length. To make it easier to adjust the cable length neatly, a take-up roller is usually used. However, since the take-up roller rotates, it will drive one end of the cable to rotate. During this process, that end of the cable also needs to maintain a communication connection with the outside world, making it difficult to maintain the connection during the rotation.

[0004] In addition, traditional winding methods rely on the rotational traction force of the winding machine to directly wind the cable onto the take-up roller. Due to the lack of effective lateral guidance, the axial arrangement of the cable on the take-up roller is extremely irregular, and the cable is prone to accumulate in a certain area of ​​the take-up roller, resulting in messy winding.

[0005] The specific problems are as follows: Uneven cable arrangement: Cables tend to accumulate in certain areas of the take-up roller, forming humps or strand jams, while other areas are sparse or even empty. This results in a chaotic arrangement of each layer of cables, making it impossible to form a neat layered structure.

[0006] Tangled and messy: Due to uneven arrangement of the bottom layer, the upper layer cables will be embedded in the gaps of the lower layer, causing wire compression, tangling, or even knots, which seriously affects the smoothness of subsequent cable laying operations and may even damage the cables due to jamming.

[0007] Reduced capacity: Due to the messy arrangement, the volume utilization rate inside the take-up roller is greatly reduced. A roller that can originally wind 1,000 meters of yarn may only be able to wind 700-800 meters, resulting in a waste of storage space and transportation costs.

[0008] Reliance on manual labor: To address this issue, existing technologies often employ manual cable laying, where operators use tools or their hands to manipulate the cables left and right to ensure even distribution. This method is inefficient, labor-intensive, and the quality of the cable laying is highly dependent on the worker's experience, making it impossible to guarantee consistency.

[0009] Therefore, a fiber optic cable winch is needed to solve the above-mentioned technical problems. Summary of the Invention

[0010] This invention addresses the technical problems existing in the prior art by providing an optical cable winch.

[0011] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A fiber optic cable winch includes a base plate, a protective cover, a winding motor, a take-up roller, and a cable laying mechanism. The winding motor, the take-up roller, and the cable laying mechanism are all located inside the protective cover. The protective cover is fixed on the base plate. A roller bracket and a motor bracket are fixed on the base plate. The winding motor is fixedly mounted on the motor bracket. The take-up roller is rotatably mounted on the roller bracket. A drive sprocket is installed at the output end of the winding motor. A first transmission sprocket and a second transmission sprocket are installed at one end of the take-up roller. A driven sprocket is provided on the cable laying mechanism. A first chain connects the drive sprocket and the first transmission sprocket. A second chain connects the second transmission sprocket and the driven sprocket. An optical slip ring is installed at the center of the other end of the take-up roller. An internal wiring port is provided on the side of the take-up roller.

[0012] Preferably, in the above-mentioned optical cable winch, the protective cover is provided with an inlet and an external connection port, the inlet being positioned corresponding to the cable laying mechanism, and the external connection port being positioned corresponding to the photoelectric slip ring.

[0013] Preferably, in the above-mentioned optical cable winch, the cable winding mechanism includes a reciprocating screw, a guide rod, a movable base, and a guide assembly. The reciprocating screw is arranged parallel to the guide rod, the reciprocating screw is rotatably arranged, and the driven sprocket is installed at one end of the reciprocating screw.

[0014] Preferably, in the above-mentioned optical cable winch, a support frame is provided on the inner side of the protective cover, a crossbar is fixed on the top of the support frame, and two limiting rollers are installed on the crossbar, with the two limiting rollers located at both ends of the take-up roller.

[0015] Preferably, in the above-mentioned optical cable winch, the bottom of the base plate is equipped with a plurality of cushioning pads.

[0016] Preferably, in the above-mentioned optical cable winch, the guiding assembly includes a grid roller group, which includes two horizontally parallel guide rollers and two vertically parallel guide rollers.

[0017] Preferably, in the above-mentioned optical cable winch, a motor bracket is installed on the housing, a wire pulling motor is installed on the motor bracket, a wire pressing wheel is installed at the output end of the wire pulling motor, and a horizontal roller is provided at the bottom of the wire pressing wheel.

[0018] Preferably, in the above-mentioned optical cable winch, two support plates are fixed on the support frame, and both ends of the reciprocating screw and the guide rod are mounted on the support plates.

[0019] Preferably, in the above-mentioned optical cable winch, a slide rail is installed on the base, and a controller is fixedly installed on the slide rail.

[0020] The beneficial effects of this invention are: 1. Stable connection between optical cable and external components during take-up and take-up: When the take-up roller rotates, one end of the photoelectric slip ring rotates accordingly without affecting the optical cable connection. The fixed end of the photoelectric slip ring is rotatably connected to the rotating end, and the communication connection can still be maintained during the rotation. 2. Achieve high-precision and uniform cable laying: The cable laying mechanism and the take-up roller are linked synchronously to ensure that the lateral movement speed of the cable laying head is precisely matched with the rotation speed of the take-up roller. This ensures that the cable is tightly wound and coiled side by side on the take-up roller, forming an extremely regular winding layer, which completely avoids the problems of tangled and pressed cables. 3. Significantly improves the carrying capacity: The regular arrangement eliminates the ineffective gaps between cables, which can make the effective volume utilization rate of the take-up roller close to the theoretical maximum value. Under the same roller diameter, it can significantly increase the winding length of the cable, or create conditions for reducing the roller diameter and saving material costs. 4. High degree of automation, saving labor: The device can operate fully automatically without human intervention, which greatly reduces the labor intensity of operators and avoids the instability of wiring quality caused by human factors. 5. High adaptability: By changing the sprockets with different gear ratios or adjusting the pitch of the reciprocating screw, it can easily adapt to cables of different diameters. 6. Reliable structure and controllable cost: In particular, the scheme using reciprocating screw and sprocket drive has a simple structure, reliable mechanical linkage, no complicated electronic control, low failure rate, and relatively economical manufacturing and maintenance costs.

[0023] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0024] like Figures 1-12 As shown, an optical cable winch includes a base plate, a protective cover 1, a winding motor 4, a take-up roller 3, and a cable laying mechanism 5. Multiple cushioning pads are installed on the bottom of the base plate. The winding motor 4, the take-up roller 3, and the cable laying mechanism 5 are all located inside the protective cover 1, which is fixed to the base plate. A slide rail is installed on the base, and a controller is fixedly mounted on the slide rail. The position of the controller on the slide rail can be slidably changed according to specific needs, and then re-fixed.

[0025] A wire roller bracket and a motor bracket are fixed on the base plate. The winding motor 4 is fixedly mounted on the motor bracket, and the take-up roller 3 is rotatably mounted on the wire roller bracket. A drive sprocket 8 is installed at the output end of the winding motor 4. A first transmission sprocket 9 and a second transmission sprocket 10 are installed at one end of the take-up roller 3. A driven sprocket 51 is provided on the wire laying mechanism 5. A first chain connects the drive sprocket 8 and the first transmission sprocket 9, and a second chain connects the second transmission sprocket 10 and the driven sprocket 51. The rotation of the winding motor 4 drives the drive sprocket 8 to rotate. The drive sprocket 8 drives the first transmission sprocket 9 to rotate via the first chain, which in turn drives the take-up roller 3 to rotate. When the take-up roller 3 rotates, it drives the second transmission sprocket 10 to rotate. The second transmission sprocket 10 drives the driven sprocket 51 to rotate via the second chain.

[0026] A photoelectric slip ring 32 is installed at the other end of the take-up roller 3, and an internal wiring port 31 is provided on the side of the roller body of the take-up roller 3. By connecting one end of the optical cable to the rotating end of the photoelectric slip ring 32 and the fixed end of the photoelectric slip ring 32 to the external optical cable, the rotating end of the photoelectric slip ring 32 rotates with the take-up roller 3 when it rotates, without affecting the optical cable connection. The fixed end of the photoelectric slip ring 32 is rotatably connected to the rotating end, and the communication connection can still be maintained during the rotation.

[0027] The protective cover 1 is equipped with an inlet 2 and an external connection port 11. The inlet 2 is positioned corresponding to the cable laying mechanism 5, and the external connection port 11 is positioned corresponding to the photoelectric slip ring 32. A support frame is provided on the inner side of the protective cover 1. A crossbar 6 is fixed to the top of the support frame. Two limiting rollers 7 are installed on the crossbar 6. The two limiting rollers 7 are located at both ends of the take-up roller 3 to prevent the optical cable from shifting to the outside of the take-up roller 3 during the winding process.

[0028] The cable routing mechanism 5 includes a reciprocating lead screw 52, ​​a guide rod 53, a movable base 55, and a guide assembly 54. The guide assembly 54 is fixed to the top of the movable base 55. The reciprocating lead screw 52 is arranged parallel to the guide rod 53. The reciprocating lead screw 52 is rotatable, while the guide rod 53 is fixed. Two support plates are fixed on the support frame, and both ends of the reciprocating lead screw 52 and the guide rod 53 are mounted on the support plates. A driven sprocket 51 is fixed to one end of the reciprocating lead screw 52.

[0029] The movable base 55 has a guide hole and a mounting hole through it. A lead screw sleeve is fixedly installed inside the mounting hole. The reciprocating lead screw 52 passes through the inside of the lead screw sleeve, and the guide rod 53 slides through the inside of the guide hole. When an external power drives the driven sprocket 51 to rotate, the driven sprocket 51 drives the reciprocating lead screw 52 to rotate. Through the interaction between the reciprocating lead screw 52 and the lead screw sleeve, the movable base 55 oscillates back and forth along the axial direction of the reciprocating lead screw 52, ​​which in turn drives the guide assembly 54 to oscillate back and forth. The driven sprocket 51 is driven by an external transmission component. The required transmission ratio is calculated based on the cable cross-sectional diameter d and the lead screw lead, ensuring that the rotational angular velocity of the driven sprocket 51 and the take-up roller meets a certain ratio. This ensures that when the cable is wound around the take-up roller once, the movable base 55 and the guide assembly 54 move a distance equal to or slightly greater than d.

[0030] The guiding assembly 54 includes a grid roller group 549 and a housing 541. The grid roller group 549 includes two horizontally parallel guide rollers and two vertically parallel guide rollers. Both ends of the housing 541 have openings, and the grid roller group 549 is rotatably mounted at one end of the housing 541. When a cable passes through the grid roller group 549, it limits the cable's insertion position, and the rolling contact between the guide rollers and the cable also guides the cable.

[0031] In addition, when winding up the optical cable, because the optical cable has a certain degree of resilience when bent, if the end of the optical cable is not fixed after winding, the wound optical cable will automatically spring open, causing the optical cable to become messy and spread out, affecting the winding effect.

[0032] Furthermore, a motor bracket 545 is mounted on the housing 541, and a wire-pulling motor 546 is mounted on the motor bracket 545. A wire-pressing wheel 547 is mounted on the output end of the wire-pulling motor 546, and a horizontal roller 5410 is provided at the bottom of the wire-pressing wheel 547. The horizontal roller 5410 is rotatably mounted inside the housing 541. An arc-shaped groove is provided on the wire-pressing wheel 547.

[0033] The optical cable passes between the arc-shaped groove of the pressure roller 547 and the horizontal roller 5410. To ensure that the pressure roller 547 can pull the optical cable when it rotates, the angle of the motor bracket 545 is adjustable. After adjustment, it can be fixed with bolts. By adjusting the angle of the motor bracket 545, the distance between the pressure roller 547 and the horizontal roller 5410 is changed, so that there is a certain contact pressure between the pressure roller 547 and the optical cable, thereby increasing the friction between the two.

[0034] As another embodiment of the installation method of the motor bracket 545, the motor bracket 545 is rotatably mounted on the housing 541. A spring is connected between the motor bracket 545 and the housing 541. When the optical cable is not inserted, the pressure wheel 547 abuts against the horizontal roller 5410. When the optical cable is inserted, the spring force causes a certain contact pressure between the pressure wheel 547 and the optical cable.

[0035] Two guide wheels 544 are arranged between the horizontal roller 5410 and the grid roller group 549. A support rod 542 is rotatably connected to the bottom of each guide wheel 544, and the support rod 542 is fixedly connected to the housing 541 via a fixing collar 543. Each guide wheel 544 has an arc-shaped groove, through which the cable passes. Both guide wheels 544 are perpendicular to the pressure roller 547, further providing lateral positioning and guidance for the cable. Two parallel vertical rollers 548 are rotatably mounted at the opening at the other end of the housing 541.

[0036] This device, designed in a small size, is primarily used in hazardous emergency rescue situations, providing power and communication via umbilical cable for the tracked vehicle.

[0037] Working principle: The winding motor 4 rotates, driving the drive sprocket 8 to rotate. The drive sprocket 8 drives the first transmission sprocket 9 to rotate via the first chain, which in turn drives the take-up roller 3 to rotate. When the take-up roller 3 rotates, it drives the second transmission sprocket 10 to rotate. The second transmission sprocket 10 drives the driven sprocket 51 to rotate via the second chain. The driven sprocket 51 drives the reciprocating screw 52 to rotate. Through the interaction between the reciprocating screw 52 and the screw sleeve, the moving base 55 swings back and forth along the axial direction of the reciprocating screw 52, ​​which in turn drives the guide assembly 54 to swing back and forth, thus making the cable winding end move at a uniform speed and avoiding local tangling and accumulation of the cable. When winding the optical cable, at the end of the winding, because the optical cable has a certain degree of resilience when bent, the tension roller 547 can be driven to rotate by the pull motor 546, pulling the optical cable outward, thus ensuring that the optical cable on the take-up roller is tightly wound.

[0038] Meanwhile, during the cable laying process, the winding motor 4 rotates in the opposite direction, driving the pressure wheel 547 to rotate through the cable pulling motor 546. This pulls the optical cable outward through the cable inlet 2, preventing the optical cable from accumulating inside the protective cover 1, thus achieving the cable laying function.
