[0030] The above improvements are specifically as follows: Figures 1 to 3 , Figure 5As shown: Multiple lighting components 1 are installed on the bridge cables. Each lighting component 1 includes a tensioning element 2 and a lighting assembly 3. The tensioning element 2 includes an I-shaped sleeve 21. The concave surface of the I-shaped sleeve 21 has multiple through slots 212 along its circumference. The sleeve 21 has a movable block 22 inside, which is slidably connected to the through groove 212. Slider blocks are provided on both sides of the movable block 22, and the through groove 212 has corresponding grooves for the sliders. The sliders move along the grooves. An arc-shaped abutment 23 is provided at the end of the movable block 22 facing inwards, abutting against the through groove 212. The arc-shaped abutments 23 abut against each other on the cable for fixation. A driving member 24 is provided on the outward-facing end face of the movable block 22, which can drive the arc-shaped abutment 23 to move, thus fixing and disengaging the adjusting member 2 from the cable.

An LED strip 321 is installed inside the second housing 32, extending through it to an interface that connects to the interfaces of LED strips 321 inside the adjacent second housings. At night, when the power is turned on, the LED strip 321 illuminates along the cable, revealing its outline and enhancing the aesthetics of the bridge cable at night. This I-shaped sleeve 21 is suitable for installation on the cable before it is erected, and can also be installed on the bridge together with the cable.

[0031] This second embodiment is basically the same as the first embodiment above, except that: the side wall of the I-shaped sleeve 21 is provided with a notch, and a cover 4 is provided at the notch, and the cover 4 is engaged with the I-shaped sleeve 21.

[0032] The above improvements are specifically as follows: Figure 4 As shown, the side wall of the I-shaped sleeve 21 is provided with a notch, and a cover 4 is provided at the notch. The cover 4 is engaged with the I-shaped sleeve 21 to realize the connection between the cover 4 and the I-shaped sleeve 21. The retaining ring 5 is also provided with a cover 4. The I-shaped sleeve 21 with the cover 4 can be used after the bridge cable is erected or before the bridge cable is erected, and it is convenient to replace.

[0033] A method for installing a bridge cable lighting device, wherein the bridge cable lighting device is installed either during the construction of the bridge cable or after the construction of the bridge cable is completed.

[0034] When installing the bridge cable lighting device before the bridge cable construction is completed, the I-shaped sleeve 21 in the bridge cable lighting device can be selected as either 4 types with or without an opening. When installing the bridge cable lighting device after the bridge cable construction is completed, only 4 types with an opening can be selected, and the number of lighting devices can be evenly distributed according to the length of the bridge cable.

[0035] The lighting devices are installed sequentially along the bridge cable using the installation tool 6. The drive components 24 of adjacent lighting devices are interlocked to connect the lighting devices. Once the connection is complete, the second bevel gear rod 242 is rotated using the installation tool 6. The connected second bevel gear rod 242 rotates synchronously, and the first bevel gear rod 241 meshing with the second bevel gear rotates synchronously. This drives the moving block 22 to press the arc-shaped abutment block 23 against the cable, thus fixing the lighting device to the bridge cable. The size of the arc-shaped abutment block 23 can be selected according to the thickness of the bridge cable.

[0036] Connect the adjacent LED strip 321 interfaces to combine the total power supply of LED strip 321 with the power supply of bridge street lights.

[0037] Based on the above embodiments, the installation tool 6 includes a platform 61, a hinged bracket 62 is provided in the middle of the platform 61, a cylinder 65 is provided between the hinged bracket 62 and the platform 61 for driving, a rotating component 63 is provided at the end of the hinged bracket 62 for driving the driving component 24 to rotate, a cavity is provided on the hinged bracket 62 for placing the lighting component 1, and the lighting component 1 is installed sequentially on the bridge cable along the direction of the hinged bracket 62.

[0038] Based on the above embodiments, a pusher 64 on the hinged bracket 62 is also included, which can push and adjust the position of the overall lighting device on the bridge cable.

[0039] The above improvements are specifically as follows: Figure 6 , Figure 7As shown: The hinged bracket 62 is provided with a cavity for placing the lighting component 1. Due to the inconsistent inclination of the cables, the inclination of the hinged bracket 62 and the platform 61 is adjusted by the cylinder 65, so that the hinged bracket 62 and the cables are at the same inclination. The first lighting component 1 is sleeved on the cable. The second lighting component 1 is placed from the end of the hinged bracket 62. The second lighting component 1 pushes the first lighting component 1 to move. The upper end of the second bevel gear rod 242 on the second lighting component 1 is engaged with the lower end of the second bevel gear rod 242 on the first lighting component 1. Lighting components 1 are continuously installed in sequence to connect the upper and lower lighting components 1. At the same time, the interfaces of the adjacent upper and lower light strips 321 are connected. After installation, the end lighting component 1 is pushed by the pusher 64 to realize the position of the entire lighting device on the bridge cable. After placement, the second bevel gear rod 242 at the end of the rotating component 63 rotates synchronously, and the first bevel gear meshing with the second bevel gear rod 242 rotates. The rotation drives the moving block 22 and the arc-shaped abutment block 23 to move. The arc-shaped abutment block 23 is fixed against the cable to achieve fixation. The rotating component 63 is a multi-independently driven motor. At night, when the streetlights are lit, the lighting component 1 lights up synchronously. The installation of the lighting component 1 does not require the construction of a lifting platform, nor does it require workers to climb onto the cable to install the lighting fixtures. The lighting component 1 is directly pushed up in sequence by the installation tool 6, and then fixed to the bridge cable by the installation tool 6. This reduces the work risk, ensures the work safety of the workers, and reduces the time and cost of building a lifting platform.
