[0002] In telecommunications engineering construction, transmission lines (such as optical cables and coaxial cables) are exposed to the environment for extended periods and are susceptible to damage from external forces or natural factors. Traditional maintenance methods often rely on manual climbing or hoisting of equipment, resulting in low efficiency and high safety risks. While existing mobile maintenance devices can move along transmission lines, they still have the following drawbacks:

[0003] Poor adaptability: It cannot automatically adjust the clamping force according to changes in transmission line diameter or bending paths;

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] Example 1:

[0034] Please see Figures 1-5 An auxiliary device for communication engineering construction includes a support unit 1. The support unit 1 includes two coaxially arranged support frames 11 and a support column 12 connected between the two support frames 11. The support column 12 is distributed in a circumferential array and is fixedly installed between the two support frames 11 by welding or bolts.

[0035] The device also includes a drive unit 2, which is located on the outside of the support frame 11. The drive unit 2 includes a plurality of mounting blocks 21 distributed around the support frame 11. The top of the mounting block 21 is provided with a mounting groove, and a support shaft 29 is fixedly mounted in the mounting groove by bearings.

[0036] The protective post 22 is set inside the mounting groove and fixedly connected to the support shaft 29. The drive shaft 28 is rotatably mounted inside the protective post 22, and the driven wheel 27 is fixedly mounted at the top of the drive shaft 28.

[0037] The drive source 23 is fixedly installed on the top of the mounting block 21. The top of the output shaft of the drive source 23 is fixedly installed with a drive wheel 24. The drive wheel 24 and the driven wheel 27 are connected by a belt 26.

[0038] The drive source 23 includes, but is not limited to, an electric motor, which is electrically connected to an external power source and controlled by an external PLC programming program;

[0039] The tension spring 3 is connected between the outer side of the protective post 22 and the bottom of the support frame 11;

[0040] The transmission unit 5 is located at the bottom end of the protective post 22. The transmission unit 5 includes a first transmission end 51, which passes through the protective post 22 and meshes with the active tapered end 281 at the bottom end of the transmission shaft 28. The first transmission end 51 is connected to the second transmission end 53 through the connecting shaft 52. The second transmission end 53 passes through the protective post 22 and extends to the outside.

[0041] The first transmission end 51 located inside the protective column 22 has a first conical end 511, which is engaged with the active conical end 281.

[0042] The roller 4 is fixedly installed at the end of the first transmission end 51 and the second transmission end 53 away from the protective post 22.

[0043] The swing axis of the protective column 22 coincides with the axis of the support shaft 29, and the inner side of the mounting groove is an arc-shaped limiting groove that matches the swing trajectory of the protective column 22.

[0044] Both ends of the support shaft 29 are fixed in the mounting groove by rolling bearings, and the top of the protective column 22 is provided with a shaft hole that is clearance-fitted with the support shaft 29.

[0045] The axis of the tension spring 3 is arranged perpendicularly to the axis of the support shaft 29 in space. The preload of the tension spring 3 causes the bottom end of the protective column 22 to deflect toward the central axis of the support frame 11.

[0046] A tensioner 25 is provided on one side of the belt 26, and the axle of the tensioner 25 abuts against the belt 26.

[0047] Both the first transmission end 51 and the second transmission end 53 penetrate the side wall of the protective column 22 and achieve rotational sealing through waterproof bearings.

[0048] The specific implementation method is as follows: the device is sleeved on the transmission line, the tension spring 3 pulls the protective column 22 to tilt in the direction of the transmission line, so that the roller 4 presses against the surface of the transmission line. After the drive source 23 is started, the drive wheel 24 drives the driven wheel 27 to rotate through the belt 26. The active conical end 281 at the bottom of the transmission shaft 28 drives the first transmission end 51, which is transmitted to the second transmission end 53 through the connecting shaft 52, driving the two rollers 4 to rotate in the same direction, and pushing the device to move along the transmission line.

[0049] Example 2:

[0050] This embodiment provides a technical solution based on embodiment one: when the device encounters a curved section of the transmission line, the outer protective post 22 swings outward due to the bending of the line, the tension spring 3 increases the tension of the roller pressure 4 through elastic deformation, and at the same time the tension wheel 25 adjusts the tension of the belt 26 to ensure the transmission efficiency between the drive wheel 24 and the driven wheel 27, so that the device can pass through the curve smoothly.

[0051] Working principle: During use, after the drive source 23 is started, its output shaft drives the drive wheel 24 to rotate. The drive wheel 24 transmits power to the driven wheel 27 via the belt 26, driving the transmission shaft 28 to rotate synchronously. The active conical end 281 at the bottom of the transmission shaft 28 converts the vertical rotational power into the horizontal power. By engaging with the first conical end 511 of the first transmission end 51, the power is transmitted to the second transmission end 53 via the connecting shaft 52, ultimately driving the two rollers 4 to rotate in the same direction. The rollers 4 push the device to move along the transmission line through friction with the surface of the transmission line.

[0052] The tension spring 3 connects the protective column 22 to the bottom of the support frame 11. Its preload forces the bottom end of the protective column 22 to deflect towards the central axis of the support frame 11, making the roller 4 tightly adhere to the surface of the transmission line. When the diameter of the transmission line changes or the path bends, the protective column 22 swings around the support shaft 29, and the tension spring 3 adjusts the clamping force of the roller 4 in real time through elastic deformation. The arc-shaped limiting groove inside the mounting groove constrains the swing angle of the protective column 22, ensuring that the roller 4 is always within the effective contact range, avoiding damage to the transmission line due to excessive pressure or slippage due to insufficient pressure.

[0053] When there is a bend or obstacle in the transmission line, the outer protective post 22 swings outward due to the bending of the line, and the tension spring 3 is stretched to increase the clamping force of the roller 4; the inner protective post 22 swings inward to release the pressure, achieving dynamic balance. The tension wheel 25 adjusts the tension of the belt 26 through the slide groove to maintain drive stability. When one side roller 4 encounters an obstacle, the drive source 23 adjusts the speed through the controller to make the two side rollers 4 rotate at different speeds, assisting the device in crossing the obstacle;

[0054] Waterproof bearings are used at the penetration points of the first transmission end 51 and the second transmission end 53 through the protective column 22 to prevent rainwater or dust from entering the transmission unit 5. A dustproof sleeve is installed at the spline connection between the connecting shaft 52 and the second transmission end 53 to prevent foreign objects from affecting the transmission accuracy. A shock-absorbing pad is provided between the drive source 23 and the mounting block 21 to absorb vibration and extend the service life of the device.

[0055] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
