Technical Field

[0001] The utility model belongs to the technical field of road and bridge construction, and particularly relates to a lighting warning device for road and bridge construction. Background Technique

[0002] Road and bridge construction refers to the construction process of building structures such as bridges and tunnels on transportation lines such as highways, railways, and waterways to solve topographic obstacles such as rivers, valleys, and mountains. This process includes preparatory work in the early stage of the project to the implementation of construction in the later stage, as well as various aspects such as construction organization design and application of construction technologies. To sum up, the problems existing in the prior art are as follows: The lighting warning devices used in road and bridge construction include various types such as luminous warning signs, LED warning lights, and cone warning lights. The cone warning light consists of a conical roadblock and a warning light. Usually, the cone warning light has the advantages of wear-resistant and impact-resistant materials, but it is light in weight and cannot adjust the weight. In case of strong wind weather, it is easy to make the cone warning light fall over, resulting in a lack of warning indication in road and bridge construction and causing potential safety hazards. However, the existing cone warning lights used in road and bridge construction do not have components to change the weight according to the use environment. Therefore, a lighting warning device for road and bridge construction is specifically proposed to solve the above problems. Content of the Utility Model

The cone warning light consists of a conical roadblock and a warning light. Usually, the cone warning light has the advantages of wear-resistant and impact-resistant materials, but it is light in weight and cannot adjust the weight. In case of strong wind weather, it is easy to make the cone warning light fall over, resulting in a lack of warning indication in road and bridge construction and causing potential safety hazards. However, the existing cone warning lights used in road and bridge construction do not have components to change the weight according to the use environment.

[0004] The utility model is realized as follows: A lighting warning device for road and bridge construction includes a warning roadblock and a warning light. The top of the warning roadblock is fixedly connected to the bottom of the warning light. A counterweight base is movably connected to the inner cavity of the warning roadblock. A limiting rod is fixedly connected to the top of the counterweight base. A device groove is opened in the warning roadblock. Two control rods are movably connected to the inner cavity of the device groove. The top of the control rod penetrates through the device groove and extends to the outside of the inner cavity of the device groove. A moving device is arranged inside the device groove.

[0005] Preferably, the mobile device of the present utility model includes two mobile rods. An outer shell is sleeved on the surface of the mobile rod. An inner shell that cooperates with the outer shell is sleeved on the surface of the mobile rod. The inner cavity of the outer shell is movably connected to the surface of the inner shell. Springs are fixedly connected to opposite sides of the inner shell and the outer shell. Opposite sides of the two springs are fixedly connected to the inner cavity of the device groove. The springs are sleeved on the surface of the mobile rod. By providing the mobile device, when the limit block moves, the mobile device has a limiting effect on the moving position of the limit block.

[0006] Preferably, limit blocks are fixedly connected to opposite sides of the two outer shells and opposite sides of the two inner shells. One side of the limit block away from the control rod penetrates through the device groove and extends to the outside of the inner cavity of the device groove. By providing the limit block, when the warning roadblock moves to the surface of the counterweight base and the control rod is released, the restoring force generated by the spring restoring its shape will drive the limit block to snap into the inner cavity of the limit groove. The cooperation of the limit block and the limit groove has a limiting effect on the positions of the warning roadblock and the counterweight base.

[0007] Preferably, an extrusion column is fixedly connected to the top of the limit block. An extrusion rod that cooperates with the extrusion column is fixedly connected to the bottom of the control rod. The surface of the extrusion rod is in contact with the surface of the extrusion column. By providing the extrusion column and the extrusion rod, when the control rod rotates, it will drive the extrusion rod to rotate along the surface of the extrusion column. The extrusion rod will generate an extrusion force on the extrusion column. The extrusion column subjected to the extrusion force can drive the limit block to move.

[0008] Preferably, a limit outer disc is fixedly connected to the surface of the control rod. The bottom of the limit outer disc is in contact with the surface of the warning roadblock. A limit inner disc is fixedly connected to the surface of the control rod. The top of the limit inner disc is in contact with the inner cavity of the device groove. By providing the limit outer disc and the limit inner disc, when the control rod moves, it will drive the limit inner disc to rotate along the inner cavity of the device groove, and at the same time drive the limit outer disc to rotate along the surface of the warning roadblock.

[0009] Preferably, limit grooves that cooperate with the limit blocks are provided on both the left and right sides of the counterweight base. The surface of the limit block is in contact with the inner cavity of the limit groove. By providing the limit groove, when the counterweight base, the limit rod, and the counterweight block completely move into the inner cavity of the warning roadblock and the control rod is released, the restoring force generated by the spring restoring its shape will drive the limit block to snap into the inner cavity of the limit groove. The cooperation of the limit block and the limit groove has a limiting effect on the positions of the counterweight base and the counterweight block in the inner cavity of the warning roadblock.

[0010] Preferably, a counterweight block is sleeved on the surface of the limiting rod.

[0012] 1. By using the cooperation of the moving device, the moving rod, the outer shell, the inner shell and the spring, the present utility model solves the problem that the existing lighting warning devices used in bridge and road construction include various types such as luminous warning signs, LED warning lights and road cone warning lights. The road cone warning light is composed of a conical roadblock and a warning light. Usually, the material of the road cone warning light has the advantages of wear resistance and impact resistance, but it is light in weight and cannot adjust its weight. In case of strong wind weather, it is easy to make the road cone warning light fall over, resulting in the lack of warning indication in bridge and road construction and causing potential safety hazards. However, the existing road cone warning lights used in bridge and road construction do not have components that can change the weight according to the use environment.

[0013] 2. By setting the moving device, when the limiting block moves, it will drive the outer shell to move along the surface of the inner shell to the side away from each other. When the outer shell and the inner shell move, they will exert a squeezing force on the spring, causing the spring to undergo elastic deformation. The restoring force generated when the spring returns to its original shape will drive the limiting block to be stuck into the inner cavity of the limiting groove. The moving device has a limiting effect on the moving position of the limiting block. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to further understand the content, features and effects of the present invention, the following embodiments are exemplified and described in detail in conjunction with the attached drawings.

[0021] The structure of the present invention will be described in detail below with reference to the attached drawings.

[0022] As Figures 1 to 5 shown, a lighting warning device for bridge construction provided by an embodiment of the present invention includes a warning roadblock 1 and a warning light 2. The top of the warning roadblock 1 is fixedly connected to the bottom of the warning light 2. A counterweight base 3 is movably connected to the inner cavity of the warning roadblock 1. A limit rod 4 is fixedly connected to the top of the counterweight base 3. A device slot 5 is opened in the warning roadblock 1. Two control rods 14 are movably connected to the inner cavity of the device slot 5. The top of the control rod 14 penetrates through the device slot 5 and extends to the outside of the inner cavity of the device slot 5. A moving device 6 is arranged inside the device slot 5.

[0023] Referring to Figure 4 , the moving device 6 includes two moving rods 601. An outer shell 602 is sleeved on the surface of the moving rod 601. An inner shell 603 that cooperates with the outer shell 602 is sleeved on the surface of the moving rod 601. The inner cavity of the outer shell 602 is movably connected to the surface of the inner shell 603. Springs 604 are fixedly connected to the opposite sides of the inner shell 603 and the outer shell 602. The opposite sides of the two springs 604 are fixedly connected to the inner cavity of the device slot 5. The springs 604 are sleeved on the surface of the moving rod 601.

[0024] Adopting the above scheme: By arranging the moving device 6, when the limit block 7 moves, the moving device 6 has a limiting effect on the moving position of the limit block 7.

[0025] Referring to Figure 4 , limit blocks 7 are fixedly connected to the opposite sides of the two outer shells 602 and the opposite sides of the two inner shells 603. The side of the limit block 7 away from the control rod 14 penetrates through the device slot 5 and extends to the outside of the inner cavity of the device slot 5.

[0026] Adopting the above solution: By setting the limit block 7, when the warning roadblock 1 moves to the surface of the counterweight base 3 and the control rod 14 is released, the restoring force generated by the spring 604 restoring its shape will drive the limit block 7 to snap into the inner cavity of the limit groove 12. The cooperation of the limit block 7 and the limit groove 12 restricts the positions of the warning roadblock 1 and the counterweight base 3.

[0027] Reference Figure 4 , a pressing column 8 is fixedly connected to the top of the limit block 7, a pressing rod 9 that cooperates with the pressing column 8 is fixedly connected to the bottom of the control rod 14, and the surface of the pressing rod 9 is in contact with the surface of the pressing column 8.

[0028] Adopting the above solution: By setting the pressing column 8 and the pressing rod 9, when the control rod 14 rotates, it will drive the pressing rod 9 to rotate along the surface of the pressing column 8. The pressing rod 9 will exert a pressing force on the pressing column 8, and the pressed pressing column 8 can drive the limit block 7 to move.

[0029] Reference Figure 5 , a limit outer disk 10 is fixedly connected to the surface of the control rod 14, the bottom of the limit outer disk 10 is in contact with the surface of the warning roadblock 1, and a limit inner disk 11 is fixedly connected to the surface of the control rod 14, and the top of the limit inner disk 11 is in contact with the inner cavity of the device slot 5.

[0030] Adopting the above solution: By setting the limit outer disk 10 and the limit inner disk 11, when the control rod 14 moves, it will drive the limit inner disk 11 to rotate along the inner cavity of the device slot 5, and at the same time drive the limit outer disk 10 to rotate along the surface of the warning roadblock 1. The cooperation of the limit inner disk 11 and the limit outer disk 10 restricts the rotation position of the control rod 14.

[0031] Reference Figure 2 , limit grooves 12 that cooperate with the limit block 7 are provided on both the left and right sides of the counterweight base 3, and the surface of the limit block 7 is in contact with the inner cavity of the limit groove 12.

[0032] Adopting the above solution: By setting the limit groove 12, when the counterweight base 3, the limit rod 4, and the counterweight block 13 completely move into the inner cavity of the warning roadblock 1 and the control rod 14 is released, the restoring force generated by the spring 604 restoring its shape will drive the limit block 7 to snap into the inner cavity of the limit groove 12. The cooperation of the limit block 7 and the limit groove 12 restricts the positions of the counterweight base 3 and the counterweight block 13 in the inner cavity of the warning roadblock 1.

[0033] Reference Figure 3 , a counterweight block 13 is sleeved on the surface of the limit rod 4. The number of counterweight blocks 13 is several and they are evenly distributed on the surface of the limit rod 4. The counterweight block 13 is movably connected to the inner cavity of the warning roadblock 1.

[0034] Adopting the above solution: By setting the counterweight block 13, the setting of the counterweight block 13 can enable the warning roadblock 1 to adjust its weight according to the usage environment, making the road cone warning light 2 more stable after being placed.

[0035] The working principle of the present utility model:

[0036] During use, when the road cone warning light 2 used in bridge construction needs to change its weight according to the usage environment, first, the user sleeved an appropriate amount of counterweight blocks 13 on the surface of the limiting rod 4 according to the usage environment, and then rotated the two control rods 14. When the control rod 14 rotates, it will drive the limiting outer disc 10 to rotate along the surface of the warning roadblock 1, and at the same time drive the limiting inner disc 11 to rotate along the inner cavity of the device slot 5. When the control rod 14 rotates, it will drive the extrusion rod 9 to rotate along the surface of the extrusion column 8. The extrusion force generated by the extrusion rod 9 on the extrusion column 8 will drive the two extrusion columns 8 to move to the opposite sides. When the extrusion column 8 moves, it will drive the two limiting blocks 7 to move away from each other. When the limiting block 7 moves, it will drive the outer shell 602 to move away from each other along the surface of the inner shell 603, and the outer shell 602 and the inner shell 603 will simultaneously move along the surface of the moving rod 601. When the outer shell 602 and the inner shell 603 move, they will generate an extrusion force on the spring 604, causing the spring 604 to undergo elastic deformation. When the limiting block 7 disengages from the limiting slot 12 and completely moves into the inner cavity of the device slot 5, the warning roadblock 1 is moved to the surface of the counterweight base 3. When the warning roadblock 1 moves, it will drive the counterweight base 3, the limiting rod 4, and the counterweight blocks 13 to completely move into the inner cavity of the warning roadblock 1. Then, the control rod 14 is released, and the restoring force generated by the spring 604 restoring its shape will drive the limiting block 7 to snap into the inner cavity of the limiting slot 12. The combined use of the limiting block 7 and the limiting slot 12 has a limiting effect on the positions of the warning roadblock 1, the counterweight blocks 13, and the counterweight base 3. The setting of the counterweight blocks 13 has an adjusting effect on the weight of the road cone warning light 2, which can increase the stability of the road cone warning light 2. At this time, the road cone warning light 2 used in bridge construction has completed the weight change according to the usage environment.

[0037] In summary: For the lighting warning device for bridge construction, by the combined use of the moving device 6, the moving rod 601, the outer shell 602, the inner shell 603, and the spring 604, it solves the problem that the existing lighting warning devices used in bridge construction include various types such as luminous warning signs, LED warning lights, and road cone warning lights. The road cone warning light consists of a conical roadblock and a warning light. Usually, the material of the road cone warning light has the advantages of wear resistance and impact resistance, but it is light in weight and cannot adjust its weight. In case of strong wind weather, it is easy to overturn the road cone warning light, resulting in a lack of warning indication in bridge construction and causing potential safety hazards. However, the existing road cone warning lights used in bridge construction do not have components that can change their weight according to the usage environment.
