Optical fiber cable take-up and pay-off device

Abstract

This utility model provides a fiber optic cable winding and unwinding device, relating to the field of fiber optic cable technology. It includes a movable base with an adaptive adjustment mechanism on top. The adaptive adjustment mechanism includes a mounting cover, the lower end of which is fixedly connected to the upper end of the movable base. The cleaning bristles inside the silicone cleaning tube effectively clean dirt from the surface of the fiber optic cable. The silicone material and the silicone protection at both ends significantly reduce contact friction with the fiber optic cable. The silicone cleaning tube also allows for adaptive fine-tuning as the fiber optic cable deviates during winding, preventing damage from hard friction. A servo motor drives a reciprocating screw, combined with a limiting slide bar and a threaded moving block, causing the mounting base to move the fiber optic cable back and forth, achieving uniform winding. Support rollers on the mounting base convert the sliding friction between the fiber optic cable and the mounting base into rolling friction. Side limiting rollers prevent lateral deviation and friction of the fiber optic cable, further protecting it and effectively preventing damage. This improves winding and unwinding efficiency and extends the cable's lifespan.

Description

Technical Field

[0001] This utility model relates to the field of optical fiber and cable technology, and in particular to a take-up and take-up device for optical fiber and cable. Background Technology

[0002] Optical cables are manufactured to meet optical, mechanical, or environmental performance specifications. They are communication cable assemblies that use one or more optical fibers placed in a sheath as the transmission medium and can be used individually or in groups. The basic structure of an optical cable generally consists of several parts, such as the cable core, reinforcing steel wires, filler, and sheath. In addition, depending on the needs, there may be waterproof layers, buffer layers, insulated metal wires, and other components. When optical cables are being wound up and used, they inevitably rub against the ground, causing dirt to adhere to the optical cable after winding.

[0003] For example, a fiber optic cable take-up and drop device disclosed in Chinese patent literature (publication number: CN221459520U) uses an inner rod, an outer rod, a fixed rod, slot A, slot B, a support rod, a cylinder, and a cleaning brush. In use, the bottom of the outer rod is fixedly connected to the base, and the inner rod is slidably connected to the outer rod. Multiple slots A are opened on the outer side wall of the inner rod. The top slot A of the inner rod is fixedly connected to the fixed rod, and the outer side wall of the fixed rod is fixedly connected to the cylinder. The inner wall of the cylinder is fixedly connected to the brush. When the operator is taking up or dropping the optical cable, the inner rod can be adjusted to a suitable height so that slots A and B are on the same horizontal plane. The support rod passes through slots A and B to fix the inner rod, and then the optical cable is passed through the cylinder, thereby achieving the function of cleaning the optical cable.

[0004] However, the cleaning cylinder is designed with a fixed posture, while the optical cable needs to rely on the reciprocating movement of the threaded block along the reciprocating screw to guide the optical cable to be evenly wound on the optical cable reel through the positioning hole. This causes the optical cable's routing trajectory to move laterally, creating a continuous dynamic deviation from the fixed guiding direction of the cylinder. When the threaded block moves the optical cable to one side, the optical cable will form an inclined contact angle with the outer edge of the cylinder after passing through it. The winding tension makes the optical cable adhere tightly to the edge of the cylinder and generate sliding friction. This continuous edge friction will gradually wear down the outer sheath, which can easily lead to longitudinal cracking of the outer sheath and reduce the protective performance. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the tendency for significant friction to occur during the winding of optical cables, which can easily lead to longitudinal cracking of the outer sheath and reduce protective performance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

A support rod is fixedly connected to the upper end of the sliding ball. A silicone cleaning tube is fixedly connected to the upper end of the support rod. An annular protective block is fixedly sleeved on the outside of the support rod.

[0009] A uniform winding mechanism is provided above the movable base.

[0010] Preferably, the silicone cleaning tube is provided with cleaning bristles arranged in a ring array inside, the lower end of the ball is fixedly connected to a reset rod, and the lower end of the reset rod is fixedly connected to a tension spring arranged in a ring array outside.

[0011] Preferably, one end of each of the plurality of tension springs is fixedly connected to the inner wall of the mounting cover, and a push handle is fixedly connected to the upper end of the movable base.

[0012] Preferably, the uniform winding mechanism includes upright plates, the lower ends of the two upright plates are symmetrically distributed and fixedly connected to the upper end of the movable base, and the inner walls of the two upright plates are rotatably connected to rotating rods through bearings.

[0013] Preferably, a winding reel is fixedly sleeved on the outside of the rotating rod, a servo motor is fixedly installed on one side of one of the upright plates, and a reciprocating screw is fixedly installed on the output shaft of the servo motor through a coupling. One end of the reciprocating screw passes through to one side of the other upright plate and is fixedly sleeved with a drive pulley.

[0014] Preferably, the external drive pulley is connected to a drive belt, the inner side of the drive belt is connected to a driven pulley, the inner wall of the driven pulley is fixedly sleeved with one end of the rotating rod, and a threaded moving block is provided on the outside of the reciprocating screw, and a limit sliding rod is slidably sleeved on the inner wall of the threaded moving block.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, the cleaning bristles inside the silicone cleaning tube can effectively clean dirt from the surface of the optical cable. The silicone material and the silicone protection at both ends can significantly reduce contact friction with the optical cable. The silicone cleaning tube can also adaptively adjust to the offset of the optical cable during winding, preventing damage to the optical cable due to hard friction. The annular protective block can also limit the tilt angle rotation of the silicone cleaning tube. Furthermore, the servo motor drives the reciprocating screw, which, combined with the limiting slide bar and the threaded moving block, causes the mounting base to move the optical cable back and forth, achieving uniform winding. The support roller on the mounting base changes the sliding friction between the optical cable and the mounting base into rolling friction. The side limiting roller prevents the optical cable from shifting to the left or right, further protecting the optical cable and effectively avoiding damage to the optical cable, improving winding efficiency and extending the service life of the optical cable.

[0027] Example

[0028] like Figures 1-4 As shown, this utility model provides a technical solution: a fiber optic cable take-up and take-up device, including a movable base 1, which serves as the supporting foundation for the entire device, facilitating the movement of the device between different work sites and enhancing the flexibility and applicability of the device. An adaptive adjustment mechanism is provided above the movable base 1.

[0029] The adaptive adjustment mechanism includes a mounting cover 2, the lower end of which is fixedly connected to the upper end of the movable base 1, providing installation space and support for the various components of the adaptive adjustment mechanism. A spherical groove 21 is provided at the center of the upper end of the mounting cover 2 to accommodate and guide the rotation of the slider 22, so that the slider 22 can flexibly adjust its angle.

[0030] The inner wall of the spherical groove 21 is rotatably connected to a ball 22, which can rotate freely within the spherical groove 21, providing a basis for the adaptive angle adjustment of the silicone cleaning tube 24. The upper end of the ball 22 is fixedly connected to a support rod 23, which serves to connect the ball 22 and the silicone cleaning tube 24 and transmit the power for angle adjustment.

[0031] The upper end of the support rod 23 is fixedly connected to a silicone cleaning tube 24. The silicone material and the silicone protection at both ends can greatly reduce the contact friction with the optical cable and avoid damage to the optical cable caused by hard friction. At the same time, the cleaning bristles 26 arranged in a ring array inside can effectively clean the dirt on the surface of the optical cable and achieve the cleaning function.

[0032] The support rod 23 is externally fixed with an annular protective block 25, which contacts the upper end of the mounting cover 2 to limit the elevation angle rotation of the silicone cleaning tube 24, prevent excessive rotation, and ensure a reasonable adjustment range.

[0033] A reset rod 27 is fixedly connected to the lower end of the slider 22, which is used to connect the tension spring 28 and transmit the elastic force of the tension spring 28. Tension springs 28 arranged in a ring array are fixedly connected to the lower end of the reset rod 27. One end of each tension spring 28 is fixedly connected to the inner wall of the mounting cover 2. When the torque of the optical cable on the silicone cleaning tube 24 disappears, the elastic force of the tension spring 28 drives the silicone cleaning tube 24 to reset through the reset rod 27, so that it returns to the initial position and is ready for the next adaptive adjustment.

[0034] The upper end of the mobile base 1 is fixedly connected to a push handle 29, which makes it convenient for the operator to push the device to move.

[0035] A uniform winding mechanism is provided above the mobile base 1. The uniform winding mechanism includes two upright plates 3. The lower ends of the two upright plates 3 are symmetrically distributed and fixedly connected to the upper end of the mobile base 1, providing installation support for the various components of the uniform winding mechanism.

[0036] The inner walls of both upright plates 3 are rotatably connected to rotating rods 31 via bearings, which drive the winding reel 32 to rotate, thereby winding the optical cable. The winding reel 32 is fixedly sleeved on the outside of the rotating rod 31 and is the core component for winding the optical cable. A servo motor 33 is fixedly installed on one side of one of the upright plates 3 to provide power for the uniform winding mechanism.

[0037] The output shaft of the servo motor 33 is fixedly mounted with a reciprocating lead screw 34 via a coupling, which is used to drive the threaded moving block 38 to perform reciprocating linear motion. One end of the reciprocating lead screw 34 passes through to one side of another vertical plate 3 and is fixedly sleeved with a drive pulley 35, which drives the driven pulley 37 to rotate via a transmission belt 36.

[0038] The drive pulley 35 is externally connected to a drive belt 36 for transmitting power to the drive pulley 35. The drive belt 36 is internally connected to a driven pulley 37. The inner wall of the driven pulley 37 is externally fixedly sleeved with one end of the rotating rod 31, transmitting the power of the drive pulley 35 to the rotating rod 31 and driving the winding reel 32 to rotate.

[0039] A threaded moving block 38 is provided on the outside of the reciprocating screw 34. Its inner wall is threadedly engaged with the reciprocating screw 34. When the reciprocating screw 34 rotates, it makes reciprocating linear motion. The inner wall of the threaded moving block 38 is slidably sleeved with a limit slide rod 39 to limit and guide the movement of the threaded moving block 38 and ensure that it moves along a straight line.

[0040] The two ends of the limiting slide bar 39 are fixedly connected to the opposite side of the two upright plates 3, respectively, to provide installation support for the limiting slide bar 39. The upper end of the threaded moving block 38 is fixedly connected to the mounting base 310, which is used to install the support roller 311 and the side limiting roller 312. The inner walls on both sides of the mounting base 310 are rotatably connected to the support roller 311 through bearings. When the optical cable moves, the support roller 311 rotates, changing the sliding friction between the optical cable and the mounting base 310 into rolling friction, thereby reducing the wear of the optical cable.

[0041] The upper end of the mounting base 310 is rotatably connected to symmetrically distributed side limiting rollers 312 via bearings to prevent the optical cable from shifting to the left or right and causing friction, thus further protecting the optical cable.

[0042] It should be noted that the electrical components mentioned above are all existing mature technologies, and appropriate models and power can be selected based on the technical knowledge of those skilled in the art, so they will not be described in detail here.

[0043] The working process of this utility model:

[0044] Step 1: Start the servo motor 33. The output shaft of the servo motor 33 drives the reciprocating screw 34 to rotate via a coupling. Since the inner wall of the threaded moving block 38 outside the reciprocating screw 34 is slidably engaged with the limiting slide rod 39, the threaded moving block 38 will reciprocate linearly along the limiting slide rod 39 when the reciprocating screw 34 rotates. The mounting base 310 at the upper end of the threaded moving block 38 will reciprocate accordingly, and the support roller 311 and side limiting roller 312 on the mounting base 310 will also move synchronously, supporting... Roller 311 rotates as the optical cable moves, converting sliding friction into rolling friction and reducing optical cable wear. The two side limiting rollers 312 restrict the optical cable from shifting left and right, preventing friction damage caused by the shift. At the same time, the drive pulley 35 rotates with the reciprocating screw 34, driving the driven pulley 37 to rotate through the transmission belt 36. The inner wall of the driven pulley 37 is fixedly sleeved with the outer end of one end of the rotating rod 31, thereby causing the rotating rod 31 to rotate. The winding reel 32 outside the rotating rod 31 rotates accordingly to wind up the optical cable.

[0045] Step two: When the optical cable passes through the silicone cleaning tube 24, the cleaning bristles 26 inside the tube clean the dirt on the surface of the optical cable. When the threaded moving block 38 moves the optical cable to one side, the optical cable generates torque on the silicone cleaning tube 24. The silicone cleaning tube 24 drives the slider 22 to rotate in the spherical groove 21 through the support rod 23. The reset rod 27 at the lower end of the support rod 23 then drives the tension spring 28 to stretch. At this time, the silicone cleaning tube 24 will adaptively and finely adjust with the moving direction of the threaded moving block 38. Its silicone material and the silicone protection at both ends reduce the contact friction with the optical cable. The annular protective block 25 contacts the upper end of the mounting cover 2, limiting the elevation angle rotation of the silicone cleaning tube 24 to prevent excessive rotation. When the threaded moving block 38 moves to the other side, the torque of the optical cable on the silicone cleaning tube 24 disappears. The elastic force of the tension spring 28 drives the silicone cleaning tube 24 to reset through the reset rod 27, returning it to its initial position. When it is necessary to release the optical cable, the operator can pull it out in the opposite direction to release the optical cable.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
