Description

Technical Field

[0001] The present invention relates to the technical field of bridge cable-stayed lighting engineering, in particular to a method and device for laying earthquake-proof lighting strips for bridge cable-stayed cables. Background Art

[0002] Illuminating bridge cables is an important component of bridge lighting projects. Existing cable lighting methods primarily involve securing light strips along the installed cables. This involves first gluing a U-shaped plastic shell along the cable, then placing the light strip inside the U-shaped plastic shell, and finally securing it with cable ties or wire. This requires heavy workload for workers, who must carry the lamps and clips along the cables during construction, creating a dangerous and inefficient process. Furthermore, due to the inherent gravity of the light strip and plastic shell, if the adhesive fails during cable vibration, the light strip will tend to move around the cable toward the lower side of the cable cross section, essentially rotating around the cable axis. Cables inevitably experience wind and rain vibration during use. If one or more clips become loose during vibration, a chain reaction will occur with the light strip and clips attached to the cable. With the loose clip as the center, the clips on both sides will loosen or break in turn, ultimately causing the entire light strip to completely detach from the cable, posing a danger to pedestrians and vehicles.

[0003] Similar to the prior art, patent document CN211176469U discloses a dedicated lighting fixture for bridge cable illumination. This fixture essentially addresses the issue of securing the light strip during use, utilizing a counterweight to address the issue of light strip rotation. Even so, the light strip still has the potential to rotate and the risk of rapid detachment. Furthermore, patent document CN115538287A discloses a bridge cable illumination device and installation method. This solution utilizes a tightening member 2 to secure the light fixture assembly 3 to the cable. While this essentially addresses the aforementioned issue, patent document CN111636313B discloses an installation and maintenance system and construction method for bridge cable illumination. While this system addresses the difficulty of carrying tools and the need to occupy the road during construction, it still fails to address the heavy workload associated with light strip installation, the tendency of the light strip to detach during later use, and the chain reaction associated with the existing installation method.

[0004] A method for laying light strips in cable lighting and a device for implementing the method are now provided, thereby solving the problem that the light strips are easily rotated around the cable axis during wind and rain vibration. At the same time, it can solve the problem that the light strip fixing components are continuously broken during vibration, causing the light strip to fall off quickly. It also saves workers from having to work at height for a long time, reduces work intensity, and can ensure that the light strip will not fall off quickly when the light strip partially falls off, which can buy time for maintenance. Summary of the Invention

[0005] In view of the above situation, in order to overcome the defects of the existing technology, the present invention provides a method and device for laying earthquake-proof lighting light strips on bridge inclined cables, which effectively solves the problems of the existing laying method of light strips, such as the light strips are easily rotated around the cable axis during wind and rain vibration, the light strip fixing components are continuously broken during vibration, resulting in the light strips falling off quickly, workers need to work at height for a long time, the labor intensity is high, and there is no time for maintenance.

[0006] The technical solution is a method for laying earthquake-proof and lighting light strips for bridge inclined cables. First, the ends of multiple light strips are fixed to the cables with clamps, and then the multiple light strips are spirally wrapped on the surface of the cables and laid. At the same time, iron wire is used for reverse spiral wrapping. During the wrapping, part of the iron wire is on the outside of the light strip, and part is between the light strip and the cable surface, interweaving to form a mesh structure. Finally, when the end of the light strip is reached, the ends of the light strip and the iron wire are fixed to the cables to complete the laying.

[0007] The cam is fixed to the side of the vertical cylinder with a U-shaped rod, and the cam is fixed to the side of the vertical cylinder with a U-shaped rod. A sliding member capable of sliding along the sliding member has a U-shaped cross-section and can slide along the arc-shaped rod. At any time, the arc-shaped rod cooperates with at least one of the sliding members. A rotatable wire drum is provided on the lower side of the sliding member, and a rack of equal length is fixed to the upper side of the sliding member. A first motor is fixed to each arc-shaped rod, and the first motor drives the rack to rotate via a pinion. At any time, the rack cooperates with at least one of the pinions. A sensor is provided on each electric cylinder. When the rack passes by, the sensor is triggered, causing the electric cylinder to extend or retract.

[0008] When in use, the walking mechanism drives the vertical cylinder to move downward along the cable, and the light strip on the light strip disk on the lower end of the U-shaped rod unfolds along the motion trajectory. At the same time, the first motor drives the rack to rotate through the pinion, and the rack drives the sliding part to rotate around the slideway composed of multiple arc-shaped rods. When the electric cylinder is in an extended state, the light strip corresponding to the electric cylinder is on the outside of the sliding part's running track. While the sliding part rotates around the zipper, the iron wire presses the light strip against the surface of the cable; when the electric cylinder is in a retracted state, the light strip is on the outside of the sliding part's running track, and the light strip presses the iron wire against the surface of the cable; the iron wire and multiple light strips are intertwined to form a mesh structure on the surface of the cable.

[0009] Furthermore, the walking mechanism includes multiple notches on the upper end of the vertical cylinder, each notch has a rubber wheel, the multiple rubber wheels can clamp the cable, the rubber wheels are connected to a second motor, and the second motor is fixed on the outside of the vertical cylinder.

[0010] Furthermore, the rubber wheel is installed at an angle, and the plurality of second motors drive the rubber wheel to move axially along the cable while also rotating circumferentially.

[0011] Furthermore, the vertical cylinder is composed of a plurality of vertical arc-shaped plates, and two adjacent arc-shaped plates are fixed by a plurality of bolts.

[0012] Furthermore, the surface of the arc-shaped rod is spherically jointed with a plurality of balls.

[0013] The present invention is ingenious in conception and can completely solve the problem of the light strip rotating around the cable. At the same time, since the light strip and the iron wire are interwoven to form a grid structure, the light strip and the iron wire are pressed against each other, so that when the iron wire breaks locally, the light strip will not fall off quickly, which can also gain valuable time for maintenance, and also greatly reduce the workload of workers and greatly reduce the work intensity of workers.

[0020] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0021] Depend on Figures 1 to 6 A method for laying earthquake-proof and lighting light strips for bridge inclined cables is provided. First, the ends of multiple light strips are fixed to the cable 1 with a clamp, and then the multiple light strips are spirally wound on the surface of the cable 1 and laid. At the same time, iron wire 2 is used for reverse spiral winding. During the winding, part of the iron wire 2 is on the outside of the light strip, and part is between the light strip and the surface of the cable 1, interweaving with each other to form a mesh structure. Finally, when the end of the light strip is reached, the light strip and the end of the iron wire 2 are fixed to the cable 1 to complete the laying.

[0022] The cam 3 is connected to the vertical tube 3 by a U-shaped rod 4, and the cam 3 is connected to the vertical tube 3 by a U-shaped rod 4. The movable sliding member 8 has a U-shaped cross-section and can slide along the arc-shaped rod 7. At any time, the arc-shaped rod 7 cooperates with at least one of the sliding members 8. A rotatable wire drum 9 is provided on the lower side of the sliding member 8, and a rack 10 of the same length is fixed on the upper side of the sliding member 8. A first motor 11 is fixed to each arc-shaped rod 7. The first motor 11 drives the rack 10 to rotate via a pinion 12. At any time, the rack 10 cooperates with at least one of the pinions 12. Each electric cylinder 5 is provided with a sensor. When the rack 10 passes by, the sensor is triggered, and the electric cylinder 5 extends or contracts.

[0023] During use, the walking mechanism drives the vertical cylinder 3 to move downward along the cable 1, and the light strip on the light strip disk 6 on the lower end of the U-shaped rod 4 unfolds along the motion trajectory. At the same time, the first motor 11 drives the rack 10 to rotate through the pinion 12, and the rack 10 drives the sliding member 8 to rotate around the slideway composed of multiple arc-shaped rods 7. When the electric cylinder 5 is in an extended state, the light strip corresponding to the electric cylinder 5 is on the outside of the running track of the sliding member 8. While the sliding member 8 rotates around the zipper, the iron wire 2 presses the light strip against the surface of the cable 1; when the electric cylinder 5 is in a contracted state, the light strip is on the outside of the running track of the sliding member 8, and the light strip presses the iron wire 2 against the surface of the cable 1; the iron wire 2 and multiple light strips are intertwined to form a mesh structure on the surface of the cable 1.

[0024] In order to enable the entire device to move along the cable 1, the walking mechanism includes multiple slots at the upper end of the vertical cylinder 3, each slot has a rubber wheel 13, and multiple rubber wheels 13 can clamp the cable 1. The rubber wheel 13 is connected to a second motor 14, and the second motor 14 is fixed on the outside of the vertical cylinder 3.

[0025] In order to make the light strip spirally wound on the cable 1 so that the light strip cannot turn easily, the rubber wheel 13 is installed obliquely, and the multiple second motors 14 drive the rubber wheel 13 to move axially along the cable 1 while also rotating circumferentially.

[0026] In order to facilitate the installation of the vertical tube 3 on the installed zipper, the vertical tube 3 is composed of a plurality of vertical arc-shaped plates, and two adjacent arc-shaped plates are fixed by a plurality of bolts.

[0027] In order to reduce the friction resistance between the sliding member 8 and the arc-shaped rod 7, a plurality of balls 15 are provided on the surface of the arc-shaped rod 7 in a spherical joint.

[0028] It is worth noting that when the electric cylinder 5 extends, the slider 8 carries the wire reel 9 thereon and passes through the middle of the rectangle formed by the U-shaped rod 4 and the light strip thereon. When the electric cylinder 5 contracts, the slider 8 carries the wire reel 9 thereon and passes through the outside of the rectangle formed by the U-shaped rod 4 and the light strip thereon (between the light strip and the cable 1). Each time the sensor on the electric cylinder 5 is triggered, the electric cylinder 5 extends from the contracted state to the longest state, or contracts from the longest state to the shortest state, depending on the specific situation. For ease of understanding, the three electric cylinders 5 in this solution are assumed to be electric cylinder 5a, electric cylinder 5b, and electric cylinder 5c, respectively. In the initial state, the output shafts of electric cylinders 5a and electric cylinder 5c are extended to the farthest ends, and the output shaft of electric cylinder 5b is retracted into the cylinder body. In this way, when the slider 8 passes the U-shaped rod 4 corresponding to the electric cylinder 5a, the iron wire 2 gradually presses the light strip to the surface of the cable 1. Then, the sensor triggers the electric cylinder 5a to retract to its shortest length, so that the light strip laid by the electric cylinder 5a is outside the movement trajectory of the slider 8; the slider 8 continues to rotate, and when the slider 8 passes the electric cylinder 5b, the iron wire 2 is between the light strip and the cable 1. Then, the sensor on it triggers the electric cylinder 5b to extend, causing the light strip to press the iron wire 2 against the surface of the cable 1; the slider 8 continues to rotate, and the process of the slider 8 passing through the electric cylinder 5c is similar to the process just after passing through the electric cylinder 5a; after the slider 8 has made a certain number of turns, multiple light strips and the iron wire 2 are intertwined to form a mesh structure on the cable 1.

[0029] Of course, in order to reduce the vibration of the light strip in the wind and reduce the burden on the cable 1, the cable 1 is polished and coated with special glue before being wrapped around the light strip, so that the light strip and the cable 1 can be fully contacted and fixed, which is beneficial to reduce the local vibration and overall vibration of the light strip and the cable 1 in later use.

[0030] Three light strips are used in the present invention, but in fact the number of light strips can be an odd number, for example, 5, 7, 9... The larger the number, the less likely the light strips are to scatter.

[0031] In order to ensure that the light strip and the iron wire 2 can be firmly attached to the surface of the cable 1, dampers are installed on the central axes of the wire reel 9 and the light strip reel 6, so as to ensure that the iron wire 2 and the light strip have a certain tension during expansion, so that they can both be tightly attached to the surface of the cable 1; of course, it is not just a damper, it can also be a tension limiting structure, or a clutch. In short, as long as the purpose of "the wire reel 9 or the light strip reel 6 can only rotate when the tension is large enough" is met, it will be fine.

[0032] In the present invention, since the rubber wheel 13 in the walking mechanism has a certain angle with the cable 1, during walking, the vertical cylinder 3 advances spirally along the cable 1, so that the light strip is also laid spirally, and the winding directions of the iron wires 2 are opposite, intertwined and pressed together to form a mesh structure, which can buy time for emergency repairs in the event of local breakage. At the same time, the spirally laid light strip can completely avoid the steering problem of the light strip caused by wind and rain vibration.

[0033] When in use, first wind the light strips on the light strip reel 6 respectively, and wind a sufficient amount of iron wire 2 on the reel 9, fix the end of the light strip and the end of the iron wire 2 at the appropriate position of the cable 1, and then assemble multiple arc plates to form a vertical cylinder 3. At this time, the first motor 11 and the second motor 14 are started. The first motor 11 drives the ring gear to rotate through the pinion 12, and the ring gear drives the sliding member 8 to rotate along the slideway composed of multiple arc rods 7. The wire wheel on the sliding member 8 unfolds under the tension of the iron wire 2, so that the iron wire 2 is spirally wound; during the winding of the iron wire 2, the electric cylinders 5 cooperate with each other to make the iron wire 2 and multiple light strips interwoven and pressed to form a mesh structure; after the walking mechanism drives the entire device to move to the appropriate position, the first motor 11 and the second motor 14 stop rotating, and fix the end of the light strip and the end of the iron wire 2 on the cable 1. At this time, the laying of the light strip on the cable 1 is completed.

[0034] The traditional installation method uses a U-shaped groove structure made of PVC material. Since the light strip is on one side of the cable 1, the brightness of the light observed at different angles is different, which seriously affects the quantitative effect. Moreover, the problem of the light strip turning is prone to occur during use. To this end, the present invention adopts a winding method to lay the light strip on the circumference of the cable 1, and uses a counter-rotating wire 2 to bind and fix the entire light strip on the cable 1, ensuring the lighting effect and solving the problem of the light strip turning.

[0035] The present invention is ingenious in conception and can completely solve the problem of the light strip rotating around the cable 1. At the same time, since the light strip and the iron wire 2 are interwoven to form a grid structure, the light strip and the iron wire 2 are pressed against each other. In this way, when the iron wire 2 breaks locally, the light strip will not fall off quickly, which can also gain valuable time for maintenance, while greatly saving manpower and material resources and greatly reducing the workload of workers.
