Description

Technical Field

[0001] This invention relates to the field of road construction lighting technology, specifically to a lighting device for road construction and its usage method. Background Technology

[0002] Lighting devices for road construction and their usage methods are key equipment and operating systems for ensuring safety and improving construction accuracy during road construction in nighttime or dimly lit environments. Their core is to provide sufficient and uniform light to the construction work area through the reasonable layout of lighting devices.

[0003] In bridge and road construction, work at the bottom of bridges, such as bearing inspection, beam crack repair, and pipeline installation, is a common and critical construction scenario. Especially when bridges cross rivers, the working environment is unique and complex, directly affecting construction efficiency and safety. However, in practice, the installation of traditional construction lighting devices faces significant challenges when illuminating the bottom of bridges over rivers: traditional lighting relies on ground supports for fixation, but there is a height difference between the bottom of the bridge and the river surface, and the ground supports cannot extend across the river to the work point. If lighting equipment is suspended from the bridge deck, the suspension cables are easily affected by the wind on the river surface, causing the lighting position to shift and the light to be unstable. Based on this, the present invention purposefully provides a road construction lighting device and its usage method that can adapt to the working environment at the bottom of bridges and roads over rivers and is easy to install quickly. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a lighting device for road construction and its usage method, thereby solving the technical problems in the prior art.

[0005] The objective of this invention can be achieved through the following technical solutions: A lighting device for road construction, comprising: A base is placed on the bridge surface. A lifting frame is installed on the base. One end of the lifting frame extends beyond the guardrail to the outside of the bridge surface, and a fixed plate is fixedly installed at this end of the lifting frame. A rotating frame is rotatably installed on the fixed plate. The rotating frame is driven to rotate by a first output source built into the fixed plate. The rotating frame is initially horizontally positioned. A telescopic frame is slidably installed inside the rotating frame. The telescopic frame is driven to move by a drive assembly. A rotating rod is rotatably installed inside the telescopic frame. The rotating rod is driven to rotate by a drive source fixedly installed at one end of the telescopic frame. The other end of the rotating rod extends outside the telescopic frame. A connecting frame is provided, one end of which is fixedly connected to a rotating rod via a quick-connect assembly, and the connecting frame is rotatably connected to a telescopic frame. An extension frame is provided at the end of the connecting frame away from the telescopic frame, and a rotating bracket is rotatably installed inside the extension frame. The rotating bracket is driven to rotate by a second output source built into the extension frame. A U-shaped seat is fixedly installed at the end of the rotating bracket away from the extension frame, and a lighting component is fixedly installed on the U-shaped seat. In its initial state, the rotating bracket is stored inside the connecting frame.

[0006] As a further embodiment of the present invention: the lifting frame is slidably mounted on the base, a hydraulic rod is fixedly mounted on the base, the movable end of the hydraulic rod is fixedly connected to the bottom of the lifting frame, the lifting frame is driven to lift by the hydraulic rod, a sleeve is fixedly mounted on the top of the base, a guide rod is fixedly mounted on the bottom of the lifting frame away from the fixed plate, the guide rod is slidably inserted into the sleeve, and two opposing clamping plates are slidably mounted on the bottom of the lifting frame, the two clamping plates are used to clamp and fix the guardrail.

[0007] As a further embodiment of the present invention: the driving assembly includes a first rack plate and a first gear. The first rack plate is fixedly installed on one side of the telescopic frame and slidably installed in the rotating frame. The first gear is rotatably installed in the rotating frame and meshes with the first rack plate. The first gear is driven to rotate by a third output source built into the rotating frame.

[0008] As a further embodiment of the present invention: the extension frame is slidably installed inside the connecting frame, a second rack plate is fixedly installed on one side of the extension frame, the second rack plate is slidably installed inside the connecting frame, a second gear is rotatably installed inside the connecting frame, the second gear is driven to rotate by a fourth output source built into the connecting frame, the second gear meshes with the second rack plate, a limit plate is fixedly installed on the connecting frame, and the limit plate abuts against the top of the extension frame.

[0009] As a further aspect of the present invention: the quick-connect assembly includes a through hole, a socket, a fastening bolt, and a mounting hole. The through hole is located at one end of the rotating rod, and the mounting hole is located at the end of the connecting frame facing the telescopic frame. The mounting hole is slidably inserted into the rotating rod. The socket is located at the end of the connecting frame near the telescopic frame. The socket and the mounting hole are connected, and the axis of the socket is perpendicular to the axis of the mounting hole. When the rotating rod is inserted into the mounting hole so that the through hole and the socket are aligned, the fastening bolt passes through the socket and the through hole and tightens, thereby establishing a rigid connection between the connecting frame and the rotating rod.

[0010] As a further aspect of the present invention: two fixed blocks are fixedly installed at one end of the telescopic frame facing the connecting frame. The two fixed blocks are symmetrically arranged about the axis of the rotating rod, and a telescopic block is slidably installed inside each of the two fixed blocks. The telescopic blocks are driven to move by the telescopic components built into the fixed blocks. The two telescopic blocks move towards each other. Locking holes corresponding to the telescopic blocks are opened at both ends of the connecting frame. When the rotating rod drives the connecting frame to rotate so that the locking holes are aligned with the telescopic blocks, the telescopic components drive the telescopic blocks to slide into the locking holes.

[0011] As a further aspect of the present invention: a storage box is fixedly installed on the end of the connecting frame away from the extension frame. When the rotating bracket is in its initial state, the U-shaped seat and the lighting component are both located inside the storage box.

[0012] A method of using a road construction lighting device, the method being applied to the road construction lighting device as described above, the method comprising the following steps: Step S1: First, place the base on the edge of the bridge deck near the guardrail, so that the fixing plate on the lifting frame extends beyond the bridge deck; Step S2: Then, the rotating frame is driven to rotate by the first output source, so that the telescopic frame rotates to a vertical position, and the connecting frame is located below the bridge surface; Step S3: Drive the rotating rod through the drive source to rotate the connecting frame, so that the rotation path of the rotating bracket is parallel to the bridge deck railing; Step S4: Activate the second output source to drive the rotating bracket to rotate and unfold to a horizontal state; Step S5: Drive the rotating rod to rotate through the drive source, thereby driving the connecting frame to rotate, so that the U-shaped seat and lighting components on the rotating bracket rotate to the bottom of the bridge, and then the lighting components can illuminate the construction site at the bottom of the bridge.

[0013] The beneficial effects of this invention are: 1. In this invention, there is no need to build a ground support. By placing the base on the bridge deck, one end of the lifting frame extends beyond the guardrail to the outside of the bridge deck. Combined with the rotation of the rotating frame, the telescopic frame and the connecting frame are turned from horizontal to vertical, allowing the lighting components to extend from the bridge deck to the bottom of the bridge. At the same time, each support component forms a rigid support, instead of the traditional suspended cable. This completely avoids the problem of the river surface obstructing the construction of the ground support, and also avoids the swaying of the suspended lighting due to the wind force on the river surface. This ensures that the lighting components are always stably aligned with the construction site at the bottom of the bridge, guaranteeing the lighting accuracy.

[0014] 2. In this invention, the telescopic frame and the connecting frame are quickly separated by a quick-connect assembly. During disassembly, the fastening bolts are pulled out to separate the rotating rod from the mounting hole, thus separating the connecting frame and the telescopic frame. After disassembly, only the telescopic frame is located on the rotating frame, shortening the overall length of the device. This facilitates transportation and turning on narrow bridge surfaces. The device can also be assembled on both sides of the bridge surface to achieve simultaneous lighting at construction points on both sides of the bridge. Furthermore, when the lighting assembly is working, the telescopic frame and the connecting frame are rigidly connected through the telescopic block and the locking hole, ensuring that the connecting frame does not shake when the lighting assembly is illuminating, thus improving the accuracy of the lighting.

[0015] 3. In this invention, starting the third output source drives the first gear to rotate, which in turn drives the telescopic frame to slide along the rotating frame via the first rack plate. This allows the height of the lighting components to be adjusted to suit different bridge under clearances. Meanwhile, starting the fourth output source drives the second gear to rotate, which in turn drives the extension frame to slide along the connecting frame via the second rack plate. This allows the distance between the lighting components and the construction point to be adjusted to suit different construction needs. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8 As shown, the present invention is a lighting device for road construction, comprising: A base 1 is placed on the bridge deck. A lifting frame 2 is provided on the base 1. One end of the lifting frame 2 extends beyond the guardrail to the outside of the bridge deck, and a fixed plate 4 is fixedly installed at this end of the lifting frame 2. A rotating frame 5 is rotatably installed on the fixed plate 4. The rotating frame 5 is driven to rotate by a first output source built into the fixed plate 4. The rotating frame 5 is initially horizontally arranged. A telescopic frame 6 is slidably installed inside the rotating frame 5. The telescopic frame 6 is driven to move by a drive assembly. A rotating rod 19 is rotatably installed inside the telescopic frame 6. The rotating rod 19 is driven to rotate by a drive source 20 fixedly installed at one end of the telescopic frame 6. The other end of the rotating rod 19 extends outside the telescopic frame 6. A connecting frame 7 is provided, one end of which is fixedly connected to a rotating rod 19 via a quick-connect assembly, and the connecting frame 7 is rotatably connected to a telescopic frame 6. An extension frame 8 is provided at the end of the connecting frame 7 away from the telescopic frame 6. A rotating bracket 9 is rotatably installed inside the extension frame 8. The rotating bracket 9 is driven to rotate by a second output source built into the extension frame 8. A U-shaped seat 10 is fixedly installed at the end of the rotating bracket 9 away from the extension frame 8. A lighting component 11 is fixedly installed on the U-shaped seat 10. The rotating bracket 9 is initially stored inside the connecting frame 7.

[0021] In one embodiment, the base 1 can be fixedly mounted on a vehicle, and the vehicle drives the base 1 and the components on the base 1 to move, thereby illuminating the underside of the bridge at different locations on the bridge road. The first output source, the second output source, and the drive source 20 can all be servo motors, servo motors, or other mechanisms capable of rotational movement. This embodiment does not impose specific limitations on these components. The lighting assembly 11 includes LED lights, a power supply battery, connecting cables, a support bracket, and a rotating mechanism. All of these components are existing technologies, and this invention does not improve them. Therefore, it is not necessary to disclose their specific mechanical and circuit structures, and this does not affect the integrity of this invention.

[0022] The working principle of this invention is as follows: First, place the base 1 near the edge of the bridge deck and close to the guardrail, so that the fixing plate 4 on the lifting frame 2 extends beyond the bridge deck. At this time, as... Figure 5As shown in the example, the telescopic frame 6 is connected to the connecting frame 7 via a quick-connect assembly. At this time, as shown... Figure 6 As shown in the example, this is to avoid the overall device being too long, which would cause inconvenience in transportation and turning. Then, the first output source is activated to drive the rotating frame 5 to rotate, causing the telescopic frame 6 to change from horizontal to vertical, allowing the connecting frame 7 to descend below the bridge deck. At this point, as shown... Figure 7 Taking the example shown, the drive source 20 drives the rotating rod 19 to rotate the connecting frame 7, making the rotation path of the rotating bracket 9 parallel to the guardrail. Then, the second output source is activated to rotate and unfold the rotating bracket 9 from inside the connecting frame 7 to a horizontal position, thus avoiding the problem of the rotating bracket 9 hitting the bridge surface when unfolded. Figure 8 As shown in the example, the drive source 20 drives the rotating rod 19 to rotate the connecting frame 7, so that the U-shaped seat 10 and the lighting component 11 are aligned with the construction site under the bridge, achieving precise lighting. Figure 1 As shown in the example, there is no need to build a ground support. The fixed plate 4 on the lifting frame 2 can be extended beyond the guardrail to the outside of the bridge deck, so that the support point of the lighting component 11 is placed on the base 1 and the bridge deck, rather than below the river surface. This completely avoids the problem of the river surface obstructing the construction of the support. When the rotating bracket 9 is unfolded, it is parallel to the side of the bridge and does not extend towards the bottom of the bridge, avoiding contact with the bridge deck or guardrail. This ensures that the rotating bracket 9 can be unfolded smoothly. At the same time, the lifting frame 2, telescopic frame 6, connecting frame 7, extension frame 8 and rotating bracket 9 form a rigid support, rather than a suspended cable. This avoids the problem of traditional suspended lighting swaying due to the wind force of the river surface.

[0023] like Figures 1-5 As shown, in a preferred embodiment of the present invention, the lifting frame 2 is slidably mounted on the base 1, and a hydraulic rod 3 is fixedly mounted on the base 1. The movable end of the hydraulic rod 3 is fixedly connected to the bottom of the lifting frame 2. The lifting frame 2 is driven to lift by the hydraulic rod 3. A sleeve 28 is fixedly mounted on the top of the base 1. A guide rod 27 is fixedly mounted on the bottom of the lifting frame 2 at the end away from the fixed plate 4. The guide rod 27 is slidably inserted into the sleeve 28. Two opposing clamping plates 15 are slidably mounted on the bottom of the lifting frame 2. The two clamping plates 15 are used to clamp and fix the guardrail.

[0024] The two clamping plates 15 can be driven by two opposing electric cylinders installed in the lifting frame 2 to achieve the purpose of moving the two clamping plates 15 towards each other. Alternatively, a bidirectional lead screw and a servo motor can be rotatably installed in the lifting frame 2, and the two clamping plates 15 can be threaded to the two ends of the bidirectional lead screw respectively. The bidirectional lead screw is driven to rotate by the servo motor. Other mechanisms that can achieve the movement of the two clamping plates 15 towards each other can also be selected. This embodiment does not make specific limitations here.

[0025] In one embodiment, it should be noted that the hydraulic rod 3 described in this invention is prior art, and this invention does not improve upon it. Therefore, it is not necessary to disclose its specific mechanical and circuit structures, and this does not affect the integrity of this invention.

[0026] In practical application, this embodiment addresses the issue of the lifting frame 2 easily tipping over due to weight imbalance after extending beyond the bridge deck. The lifting frame 2 is driven to rise and fall via a hydraulic rod 3. First, the lifting frame 2 is raised above the guardrail height. This facilitates the movement of the base 1 so that the fixing plate 4 crosses the guardrail, preventing collisions between the lifting frame 2 and the guardrail. Then, after the fixing plate 4 extends beyond the bridge deck, the lifting frame 2 is driven to descend, positioning the guardrail between the two clamping plates 15. The clamping plates 15 then move towards each other to hold the guardrail in place. This solves the problem of the lifting frame 2 easily swaying when supported only by the base 1, creating a dual-stability structure combining guardrail clamping and the bottom support of the base 1. Simultaneously, as the lifting frame 2 descends, the guide rod 27 slides synchronously along the sleeve 28. The insertion and engagement of the guide rod 27 and the sleeve 28 restricts the lateral displacement of the lifting frame 2, preventing excessive weight at the extended end of the fixing plate 4 from causing the lifting frame 2 to tilt. This further enhances the stability of the device during lighting, preventing the lighting component 11 from shifting due to shaking.

[0027] like Figures 1-4 As shown, in a preferred embodiment of the present invention, the driving assembly includes a first rack plate 13 and a first gear 14. The first rack plate 13 is fixedly installed on one side of the telescopic frame 6 and slidably installed in the rotating frame 5. The first gear 14 is rotatably installed in the rotating frame 5 and meshes with the first rack plate 13. The first gear 14 is driven to rotate by a third output source built into the rotating frame 5.

[0028] Specifically, the extension frame 8 is slidably installed inside the connecting frame 7. A second rack plate 16 is fixedly installed on one side of the extension frame 8. The second rack plate 16 is slidably installed inside the connecting frame 7. A second gear 17 is rotatably installed inside the connecting frame 7. The second gear 17 is driven to rotate by a fourth output source built into the connecting frame 7. The second gear 17 meshes with the second rack plate 16. A limit plate 18 is fixedly installed on the connecting frame 7. The limit plate 18 abuts against the top of the extension frame 8.

[0029] In one embodiment, both the third and fourth output sources can be servo motors, servo motors, or other components capable of rotational motion. This embodiment does not impose specific limitations on these components.

[0030] In practical application, the height of this embodiment is adjusted as follows: the third output source is activated to drive the first gear 14 to rotate. The first gear 14 drives the telescopic frame 6 to slide along the rotating frame 5 through meshing with the first rack plate 13. This can adjust the height of the lighting component 11 to adapt to different bridge clearances and expand the lighting coverage of the lighting component 11 to adapt to various bridge types. Horizontal distance adjustment: The fourth output source is activated to drive the second gear 17 to rotate. The second gear 17 drives the extension frame 8 to slide along the connecting frame 7 through meshing with the second rack plate 16, thereby achieving the purpose of adjustable distance between the lighting component 11 and the construction point. Meanwhile, the extension frame 8 always abuts against the limiting plate 18 during the sliding process. The supporting effect of the limiting plate 18 can counteract the upward prying of the extension frame 8 and the rotating bracket 9 caused by the gravity of the lighting component 11, thus avoiding the problem of the lighting component 11 drooping when suspended and causing the lighting angle to deviate. This ensures that the lighting component 11 always remains horizontal or at the preset lighting angle, thereby improving the lighting accuracy.

[0031] like Figures 1-3 As shown, in a preferred embodiment of the present invention, the quick-connect assembly includes a through hole 21, a insertion hole 22, a fastening bolt 23, and a mounting hole 29. The through hole 21 is located at one end of the rotating rod 19, and the mounting hole 29 is located at the end of the connecting frame 7 facing the telescopic frame 6. The mounting hole 29 is slidably inserted into the rotating rod 19. The insertion hole 22 is located at the end of the connecting frame 7 near the telescopic frame 6, and the insertion hole 22 communicates with the mounting hole 29. The axis of the insertion hole 22 is perpendicular to the axis of the mounting hole 29. When the rotating rod 19 is inserted into the mounting hole 29 so that the through hole 21 and the insertion hole 22 are aligned, the fastening bolt 23 passes through the insertion hole 22 and the through hole 21 and is fastened, so that the connecting frame 7 and the rotating rod 19 are rigidly connected.

[0032] Specifically, two fixing blocks 25 are fixedly installed at one end of the telescopic frame 6 facing the connecting frame 7. The two fixing blocks 25 are symmetrically arranged about the axis of the rotating rod 19, and telescopic blocks 26 are slidably installed in both fixing blocks 25. The telescopic blocks 26 are driven to move by the telescopic components built into the fixing blocks 25. The two telescopic blocks 26 move towards each other. Both ends of the connecting frame 7 are provided with locking holes 24 corresponding to the telescopic blocks 26. When the rotating rod 19 drives the connecting frame 7 to rotate so that the locking holes 24 are aligned with the telescopic blocks 26, the telescopic components drive the telescopic blocks 26 to slide into the locking holes 24.

[0033] In one embodiment, the telescopic component can be an electric cylinder, an electric telescopic rod, or other mechanisms capable of linear reciprocating motion. This embodiment does not impose any specific limitations on these components.

[0034] In practical applications, this embodiment addresses the problem of excessive overall length of the device, which hinders bridge deck turning and transportation. A quick-connect assembly enables rapid separation of the telescopic frame 6 and the connecting frame 7. During disassembly, pulling out the fastening bolt 23 separates the rotating rod 19 from the mounting hole 29, thus separating the connecting frame 7 from the telescopic frame 6. Figure 5 As shown in the example, after disassembly, only the telescopic frame 6 is located on the rotating frame 5, and the length of the overall device is shortened, which facilitates transportation and turning on narrow bridge surfaces. It can also be assembled on both sides of the bridge surface to achieve simultaneous lighting at construction points on both sides of the bridge bottom. During assembly, after inserting the rotating rod 19 into the mounting hole 29, the through hole 21 and the insertion hole 22 are aligned and then fastened with the fastening bolt 23. A fixing block 25 is fixedly installed on the telescopic frame 6, such as... Figure 1 As shown in the example, when the drive source 20 drives the rotating rod 19 to rotate the connecting frame 7, so that the U-shaped seat 10 and the lighting component 11 are aligned with the construction site under the bridge, the locking holes 24 on both sides of the connecting frame 7 are aligned with the telescopic blocks 26 on the two fixed blocks 25 after the connecting frame 7 rotates. By driving the telescopic block 26 to insert into the locking hole 24 through the telescopic component, the telescopic frame 6 and the connecting frame 7 can establish a temporary rigid connection, forming a double rigid connection, ensuring that the connecting frame 7 does not shake when the lighting component 11 is illuminating, and improving the accuracy of the lighting.

[0035] It should be noted that there is a gap between the fixing block 25 and the connecting frame 7. When the connecting frame 7 rotates, the fixing block 25 moves away from the connecting frame 7 and does not contact the connecting frame 7.

[0036] like Figure 1 As shown, in a preferred embodiment of the present invention, a storage box 12 is fixedly installed on the end of the connecting frame 7 away from the extension frame 8. When the rotating bracket 9 is in the initial state, the U-shaped seat 10 and the lighting component 11 are both located inside the storage box 12.

[0037] In practical application, in the initial state, the rotating bracket 9 is housed within the connecting frame 7, while the U-shaped base 10 and the lighting assembly 11 are both located in the storage box 12. Figure 1 As shown in the example, the storage box 12 can block dust, rain and accidental collisions, thus avoiding the problem of the lighting component 11 being easily damaged during transportation and when not in operation.

[0038] Please see Figures 1-8 As shown, the present invention provides a method for using a road construction lighting device. The method is applied to a road construction lighting device as described in the above embodiments, and includes the following steps: Step S1: First, place the base 1 on the edge of the bridge deck near the guardrail, so that the fixing plate 4 on the lifting frame 2 extends beyond the bridge deck; Step S2: Then, the rotating frame 5 is driven to rotate by the first output source, so that the telescopic frame 6 rotates to a vertical position, and the connecting frame 7 is located below the bridge surface; Step S3: Drive the rotating rod 19 through the drive source 20 to rotate the connecting frame 7, so that the rotation path of the rotating bracket 9 is parallel to the bridge deck railing. Step S4: Start the second output source to drive the rotating bracket 9 to rotate and unfold to a horizontal state; Step S5: Drive the rotating rod 19 to rotate through the drive source 20, thereby driving the connecting frame 7 to rotate, so that the U-shaped seat 10 on the rotating bracket 9 and the lighting component 11 rotate to the bottom of the bridge, and then the lighting component 11 can illuminate the construction site at the bottom of the bridge.

[0039] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
