Description

Technical Field

[0001] This invention relates to the field of bridge cable maintenance equipment technology, specifically an automatic wrapping device for bridge cables. Background Technology

[0002] The cables or suspenders of cable-stayed bridges (such as arch bridges, cable-stayed bridges, and suspension bridges) are the main load-bearing components of the structure, and their safety and durability are crucial to the safety and normal function of the bridge structure. Bridge cables are generally protected with hot-extruded high-density polyethylene (PE) sheaths. After installation, cables are subjected to the combined effects of various loads and environmental factors such as vehicles, wind, and temperature over a long period, making the sheath surface highly susceptible to corrosion, weathering, UV aging, and impact damage. Currently, the common practice in engineering is to wrap protective tape around the surface of the cables to repair these defects. Proper wrapping can effectively extend the lifespan of the PE sheath, thereby protecting the steel wire bundles inside the cable.

[0003] Currently, the most common method for wrapping bridge suspenders is manual labor, which is unsafe for working at heights, and the wrapping installation is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an automatic wrapping device for bridge suspension cables to realize the automatic wrapping function of bridge suspension cables.

[0005] To achieve the above objectives, an automatic wrapping device for bridge suspension cables is designed, comprising: a wrapping system panel, which is a circular ring plate with a notch; a climbing cable system panel, which has a notch in the same direction as the wrapping system panel, and the climbing cable system panel and the wrapping system panel are connected by several connecting rods; several turntable drive gears, which are disposed on the upper surface of the wrapping system panel and driven by a turntable drive motor; a wrapping turntable, which is a circular ring gear plate with a notch, and the sawtooth structure on the outer side of the wrapping turntable meshes with the several turntable drive gears; the wrapping turntable is equipped with a camera, a grinder, a wrapping tape clamp, and a wrapping tape holder; and two climbing cable wheel rotating arms arranged opposite each other, one end of which is connected to the climbing cable wheel, and the other end is rotatably connected to the climbing cable wheel support disposed at the bottom of the climbing cable system panel via a rotating shaft.

[0018] like Figure 1 , 2 As shown in Figure 3, the wrapping system 1 consists of a wrapping system panel 11, a wrapping turntable 12, a turntable drive gear 13, a turntable drive motor 14, a turntable limit plate 15, a camera 16, a grinder 17, a wrapping tape clamp 18, and a wrapping tape holder 19.

[0019] The wrapping system panel 11 is a circular ring plate with a notch, the width of which is slightly larger than the diameter of the sling 5, to facilitate fitting the device onto the existing sling 5. Turntable drive motors 14 are symmetrically arranged on both sides of the wrapping system panel 11, and the end of the motor shaft of the turntable drive motor 14 is connected to the turntable drive gear 13. The wrapping turntable 12 is a circular ring gear plate with a notch. The serrated structure on the outer side of the wrapping turntable 12 meshes with several turntable drive gears 13. The wrapping turntable 12 is equipped with a camera 16, a grinder 17, a wrapping tape clamp 18, and a wrapping tape holder 19. One end of the turntable limiting plate 15 is connected to the turntable drive gear 13, and the other end covers the wrapping turntable 12, preventing the wrapping turntable 12 from disengaging from the turntable drive gear 13.

[0020] like Figure 1 , 5 As shown, the camera 16 consists of a camera 161 and a camera column 162, used to capture images of the surface of the suspension cable 5 in real time, identify surface defects, and determine the locations that need to be sanded and wrapped. The bottom end of the camera column 162 is connected to the wrapping turntable 12, and the top end is connected to the camera 161, with the camera 161 aligned with the surface of the suspension cable 5.

[0021] like Figure 1 , 6 As shown, the grinder 17 consists of a grinder base 171, a grinder shaft 172, and a grinding wheel 173, and is used to grind and clean the parts of the sling 5 that need to be wrapped. The grinder base 171 is located on the wrapping turntable 12. The grinder shaft 172 is a long rod that can rotate around the grinder base 171, and one end is connected to the grinding wheel 173.

[0022] like Figure 1 , 7 As shown, the wrapping tape clamp 18 consists of a wrapping tape clamp base 181, a wrapping tape clamp pivot 182, and a wrapping tape chuck 183. It is used to attach the end of the wrapping tape to the surface of the sling 5 at the start of wrapping. The wrapping tape clamp base 181 is located on the wrapping turntable 12. The wrapping tape clamp pivot 182 is a long rod that can rotate around the wrapping tape clamp base 181, with one end connected to the wrapping tape chuck 183. The wrapping tape chuck 183 is used to clamp the end of the wrapping tape and attach it to the surface of the sling 5.

[0023] like Figure 1 , 8As shown, the wrapping tape holder 19 consists of a wrapping tape insert shaft 191 and a wrapping tape limiting chuck 192. The wrapping tape insert shaft 191 is a cylinder that is obliquely inserted into the wrapping turntable 12, and the wrapping tape is inserted into the wrapping tape insert shaft 191. The wrapping tape limiting chuck 192 is located at the top and near the middle of the wrapping tape insert shaft 191 and is used to fix the wrapping tape. The camera 161 is positioned higher than the grinding wheel 173, and the grinding wheel 173 is positioned higher than the wrapping tape chuck 183.

[0024] like Figure 1 , 4 As shown, the climbing cable system 2 consists of a climbing cable system panel 21, a climbing cable wheel support 22, a climbing cable wheel limiting shaft 23, a climbing cable wheel rotating arm 24, a climbing cable wheel drive motor 25, and a climbing cable wheel 26.

[0025] The climbing cable system panel 21 is a circular plate with the same shape and dimensions as the wrapping system panel 11. The climbing cable system panel 21 and the wrapping system panel 11 are connected by three connecting rods 3. One end of the climbing cable wheel support 22 is connected to the climbing cable system panel 21, and the other end is hinged to the climbing cable wheel rotating arm 24 through the climbing cable wheel limiting shaft 23. One end of the climbing cable wheel rotating arm 24 is connected to the climbing cable wheel drive motor 25. The end of the motor shaft of the climbing cable wheel drive motor 25 is connected to the climbing cable wheel 26.

[0026] like Figure 1 , 3 As shown in Figure 4, the electronic control system 4 consists of a wrapping system remote control switch 41, a wrapping system battery 42, a climbing cable system remote control switch 43, and a climbing cable system battery 44. The wrapping system remote control switch 41 and the wrapping system battery 42 are fixed below the wrapping system panel 11. The wrapping system remote control switch 41 controls the opening and closing of the turntable drive motor 14 and the rotation of the grinder shaft 172 and the wrapping tape clamp shaft 182. The wrapping system battery 42 supplies power to the devices in the wrapping system 1. The climbing cable system remote control switch 43 and the climbing cable system battery 44 are fixed below the climbing cable system panel 21. The climbing cable system remote control switch 43 controls the opening and closing of the climbing cable wheel drive motor 25, and the climbing cable system battery 44 supplies power to the climbing cable wheel drive motor 25.

[0027] The working mechanism of the automatic wrapping device for bridge suspension cables is as follows: First, insert the wrapping tape into the wrapping tape insert 191 and clamp the end of the wrapping tape with the wrapping tape clamp 183. Next, at the lower part of the bridge suspension cable 5, insert the automatic wrapping device of the bridge suspension cable 5 into the suspension cable 5 to be wrapped through the notch of the wrapping system panel 11 and the climbing cable system panel 21. Adjust the position of the climbing cable wheel rotating arm 24 so that the two climbing cable wheels 26 are tightly fitted with the suspension cable 5, and tighten the climbing cable wheel limiting shaft 23 to fix the position of the climbing cable wheels 26.

[0028] Next, the remote control switch 43 of the climbing system is turned on remotely, causing the climbing wheel drive motor 25 to rotate, which in turn drives the climbing wheel 26 to rotate, enabling the device to automatically climb the cable and move upward along the suspension cable 5. The remote control switch 41 of the wrapping system is turned on remotely, causing the turntable drive motor 14 to rotate, which in turn drives the turntable drive gear 13 to rotate, which in turn drives the wrapping turntable 12 to rotate, thereby causing the camera 16 to rotate around the suspension cable 5. When the camera 161 of the camera identifies the surface defects of the suspension cable 5, the location that needs to be ground and wrapped can be determined. At this time, the remote control switch 41 of the wrapping system is turned on remotely, causing the grinder shaft 172 to rotate, so that the surface of the grinding wheel 173 is in contact with the surface of the suspension cable 5. Since the wrapping turntable 12 is still rotating at this time, it drives the grinding wheel 173 to rotate and grind the surface of the suspension cable 5.

[0029] After grinding is complete, turn off the turntable drive motor 14 and lift the grinder shaft 172 to disengage the grinding wheel 173 from the surface of the suspension cable 5. Next, turn on the wrapping system remote control switch 41 to rotate the wrapping tape clamp shaft 182, so that the end of the wrapping tape held by the wrapping tape clamp 183 is in contact with the surface of the suspension cable 5. Continue to turn on the wrapping system remote control switch 41 to rotate the turntable drive motor 14, which drives the turntable drive gear 13 to rotate, thereby driving the wrapping turntable 12 to rotate, thus wrapping the wrapping tape around the suspension cable 5, realizing the automatic wrapping function of this device.

[0030] The automatic wrapping device for bridge suspension cables can simultaneously and comprehensively identify surface defects, grind and clean the cables, and wrap them without interference. Because the grinding wheel 173 is located above and a certain distance from the wrapping tape clamp 183, when the automatic wrapping device identifies the area requiring grinding, the upper grinding wheel 173 first grinds the designated area. Then, as it continues to move upwards, the lower wrapping tape clamp 183 begins wrapping the cleaned area, ensuring that grinding and wrapping work simultaneously without interference.

[0031] The automatic wrapping device for bridge suspension cables of the present invention, through the structural design of the wrapping system panel and the climbing cable system panel, the intelligent recognition of the camera, the automatic grinding and wrapping of the grinder and wrapping tape clamp, and the remote control operation of the electrical control system, realizes the automatic identification of surface defects, automatic grinding and cleaning and automatic wrapping of bridge suspension cables 5 in an integrated manner, thereby improving the maintenance efficiency and quality of bridge suspension cables 5.

[0032] The above description is merely a specific embodiment of the invention, but the scope of protection of the invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the invention, based on the technical solutions and novel concepts of the invention, should be covered within the scope of protection of the invention.
