For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances and in combination with the prior art. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other unless there is a conflict. And one or more of the components in the diagram may be necessary or non-essential, and the relative position relationship between the components in the above diagram can be adjusted according to actual needs.

[0035] In order to realize the maintenance of the spotlight 8 without climbing up, Figures 1 to 10 As shown, the example of the present invention provides a spotlight assembly for bridge cables, which includes: a wire drum 1, a cable 2, a lamp frame unit 3, and a limiter 4, wherein the wire drum 1 includes: a drum frame 11, a wire drum wheel 12, the rotating shaft of the wire drum wheel 12 is connected to the drum frame 11, and a rope threading hole 13 is provided on one side of the drum frame 11. The wire drums 1 are arranged in groups of two, respectively disposed at the upper and lower ends of the bridge cable 9, and the cable 2 is respectively wound around the wire drum wheels 12 of the wire drums 1 at the upper and lower ends of the bridge cable 9 through the rope threading holes 13 to define two ropes, as shown in Figure 2, the left side is the pull rope 21, and the right side is the light rope 22, and the rope head at the light rope 22 (which is also the rope head of the cable 2) is fixed on the drum frame 11 of the lower end wire drum 1, and the light frame unit 3 is arranged on the light rope 22 for the matching of the spotlights 8 to distribute the spotlights 8 on the light rope 22 of the cable 2, wherein the spotlights 8 in this example are connected by a light wire to connect to the ground, and when the wire drum wheel 12 tightens the cable 2, it is matched with the pull rope 21 through the limiter 4 and abutted against the rope threading hole 13 of the drum frame 11 to tighten the cable 2, so that each spotlight 8 is maintained at the corresponding position of the bridge cable 9.

[0036] Among them, Figure 7 As shown, in the present invention, the limiting member 4 example includes: a clamping member 41 and a wire rope 42, wherein the wire rope 42 is used to thicken a small section of the rope 21 in the wire drum 1 at the lower end of the bridge cable 9, and the wire rope 42 and the section of the rope 21 are clamped by the clamping member 41, so as to form a small limiting section on the rope 21 to limit its passage through the rope threading hole 13 on one side of the drum frame 11, thereby tightening the cable 2 to prevent it from loosening, thereby fixing the various spot lights 8 distributed at various positions on the bridge cable 9.

[0037] In addition, considering that the rope 2 itself has a certain degree of stretchability, after the rope 2 is tightened by the limiter 4, it may not be possible to keep the rope 2 tight over time. Therefore, in an optional embodiment, as shown in FIG. Figure 6 , Figure 8 As shown, the spotlight assembly for bridge cables may also include: a cable tensioner 5, which is set on the light rope 22. Through this setting, while limiting the rope 21 through the limiter 4, the cable tensioner 5 can be adjusted to tighten the cable 2 again to prevent the light rope 22 from loosening and floating, and the spotlight 8 is thrown onto the bridge cable 9, causing the risk of damage to the lamp. At the same time, the distribution position of each spotlight 8 on the bridge cable 9 can be maintained, thereby improving the aesthetic coordination of landscape lighting.

[0038] Furthermore, in a preferred embodiment, in order to conveniently arrange the spotlight 8 on the lamp cord 22, as shown in FIG. Figures 4 to 5 As shown, the lamp frame unit 3 includes: a transmission bracket 31 and a snap-fit ​​member 32, wherein a fixing member 33 is provided on the back of the transmission bracket 31, and both ends of the fixing member 33 are fastened to the transmission bracket 31 by bolts, forcing the fixing member 33 to clamp the lamp cord 22 to fix the position of the transmission bracket 31 on the lamp cord 22, and the snap-fit ​​member 32 is connected to the transmission bracket 31 for snapping with the spotlight 8. With this arrangement, when the spotlight 8 needs to be repaired, it can be conveniently loaded and unloaded from the lamp cord 22.

[0039] In order to stabilize the position of the lamp rack unit 3 on the lamp cord 22 and reduce its shaking, Figure 5 As shown, in an optional embodiment, guide arms 34 can be set on both sides of the back of the transmission bracket 31, and guide holes are provided on the guide arms 34. The fixing member 33 is set on the back of the transmission bracket 31 and located between the guide arms 34. The fixing member 33 is connected to the lamp rope 22 passing through the guide arms 34, so as to fix the position of the transmission bracket 31 on the lamp rope 22.

[0040] In addition, in order to further stabilize the position of the lamp stand unit 3 on the cable 2 and prevent it from deflecting around the lamp cord 22, as shown in FIG. Figure 5 As shown, in a preferred embodiment, the length of the transmission bracket 31 can be set to cover the interval span between the pull rope 21 and the lamp rope 22, and a guide ring 35 is provided at the back of the transmission bracket 31 at the position of the pull rope 21, and the pull rope 21 passes through the guide ring 35 to limit the deflection of the transmission bracket 31. Through this arrangement, a three-point limit can be formed through two guide arms 34 and the guide ring 35, thereby stabilizing the position of the lamp rack unit 3 on the cable 2, and because the guide ring 35 does not limit the passage of the pull rope 21, it can achieve a stabilizing effect while not hindering the lifting and lowering of the lamp rack unit 3.

[0041] Further, such as Figure 1 to Figure 2As shown, in order to protect the wire drum wheel 12 , in a preferred embodiment, the spotlight assembly for bridge cables may also include: a protective cover 6 , which is connected to the drum frame 11 and covers the outside of the wire drum wheel 12 .

[0042] Further, considering that some bridge cables 9 are long, when the number of layers of the cable 2 wound on the line disc wheel 12 is too many, it is easy to be outwardly inclined and spread out. Figure 2 , Figures 6 to 10 As shown, a retaining drum 14 may be provided on the outer side of the drum wheel 12, so as to collect and coil the rope 2 together with the drum frame 11 and form protection.

[0043] In addition, in order to facilitate the winding of the cable 2 by the wire drum wheel 12 at the upper and lower ends of the bridge cable 9, as shown in FIG. Figure 2 , Figures 6 to 10 As shown, in an optional embodiment, a crank 15 is provided on the wire drum 14 located at the lower end of the bridge cable 9. Through this arrangement, it is convenient for workers to rotate the wire drum wheel 12 to coil / release the cable 2 by shaking the crank 15 on the ground, so as to control the lifting of the lamp rack unit 3.

[0044] Further, such as Figures 1 to 3 As shown, in order to arrange the spotlight 8 of the above example on both sides of the bridge cable 9, in an optional embodiment, the back of the drum frame 11 can be set to an arc shape matching the curved surface of the bridge cable 9, and clamps 16 are provided on both sides. The drum frames 11 of the pair of reels 1 are backed against the bridge cable 9 and connected to the upper and lower ends of the bridge cable 9 in pairs through the clamps 16, thereby arranging the spotlight 8 components on both sides of the bridge cable 9, forming the effect of a height-free lifting lamp.

[0045] On the other hand, corresponding to the above-mentioned example of the spotlight assembly for bridge cables, the present invention also provides a method for controlling the lifting thereof, the steps of which include:

[0046] When descending, Fig. 9 As shown, the stopper 4 matched with the pull cord 21 is released, allowing the wire drum wheel 12 to rotate and release the pull cord 21, so that the lamp rack unit 3 is lowered with the lamp cord 22 and its own gravity, and the lamp cord 22 between each lamp rack unit 3 is bent to shorten the distance between each spotlight 8. Fig. 9 As shown, the spotlights 8 finally set at the top of the light rope 22 will be lowered one by one until they overlap with the spotlights 8 at the bottom. At this time, workers can inspect and repair each spotlight 8 on the ground without setting up climbing measures.

[0047] When rising, Fig.10As shown, the rotating reel wheel 12 winds up the cable 2 to pull the pull rope 21, driving the light rope 22 to lift each lamp rack unit 3, so that the light rope 22 between each lamp rack unit 3 is straightened to restore the distance between each spotlight 8. When the distance is reached, the limit piece 4 is matched with the pull rope 21, and the cable 2 is tightened, so that each spotlight 8 can be returned to its position on the bridge cable 9.

[0048] In addition, in order to tighten the rope 2 to prevent it from drifting, in an optional embodiment, the following steps are further included:

[0049] The cable tightener 5 on the light rope 22 is adjusted to tighten the cable 2. This prevents the light rope 22 from loosening and maintains the distribution position of each spotlight 8 on the bridge cable 9.

[0050] In summary, through the spotlight lamp assembly and lifting method thereof for bridge cables provided by the present invention, a lifting structure of the spotlight lamp 8 is cleverly designed to transform the originally statically fixed spotlight lamp 8 into a dynamically liftable lamp, thereby eliminating the need for climbing measures during maintenance of the spotlight lamp 8, saving workers from having to climb, thereby reducing maintenance costs and fundamentally solving the risk of climbing for maintenance workers.
