Description

Technical Field

[0001] This utility model relates to the field of highway construction technology, and more specifically, it relates to a warning device for highway construction sites. Background Technology

[0002] Ensuring traffic safety is paramount at highway construction sites. Warning devices are necessary to effectively alert oncoming vehicles. However, existing highway construction site warning devices typically have a fixed width, meaning they cannot be adjusted to cover the entire construction area, resulting in insufficient warning effectiveness and potential safety hazards. Furthermore, these devices lack anti-tipping components, leading to poor stability. Strong winds or airflow from passing vehicles can easily cause them to tip over, further compromising their warning effectiveness and creating further safety risks. Utility Model Content

[0028] Please see Figure 1-5A warning device for highway construction sites includes two support rods 1. Each support rod 1 has a warning light 2 at its upper end. Multiple limiting shells 3 and multiple moving rods 4 are fixed to one side of each support rod 1. A drive chamber 5 is located inside the support rod 1 near the limiting shell 3. A rotating rod 6 is rotatably mounted inside the drive chamber 5. A handle 7 is fixedly mounted on the upper end of the rotating rod 6, passing through the support rod 1. A lead screw 8 is rotatably mounted inside the limiting shell 3. One end of the lead screw 8 extends into the drive chamber 5 and is fixedly mounted with a driven bevel gear 9. The driven bevel gear 9 is meshed with a drive bevel gear 10, which drives... The bevel gear 10 is fixedly connected to the rotating rod 6. One end of the moving rod 4 extends into the limiting shell 3 and is threadedly connected to the lead screw 8. A limiting block 11 is provided on one side of the moving rod 4. A limiting groove 12 that mates with the limiting shell 3 is provided on one side of the limiting shell 3. An installation frame 21 is fixedly provided on one side of the two limiting shells 3. A warning sign 22 is movably installed in the installation frame 21. A screw 23 is threaded on the upper end of the installation frame 21. One end of the screw 23 extends into the installation frame 21 and is provided with a pressing plate 24 that rotates through a bearing. A fixing rod 25 is fixedly provided at the lower end of the pressing plate 24. There are multiple fixing rods 25, and one end of each fixing rod 25 is inserted into the warning sign 22.

[0029] In this embodiment, when the entire warning device is used at a highway construction site and its width needs to be adjusted, the handle 7 is turned, which drives the rotating rod 6 to rotate. The rotating rod 6 drives multiple driving bevel gears 10 to rotate. Since the driving bevel gears 10 are meshed with the driven bevel gears 9, the multiple driven bevel gears 9 rotate simultaneously. The driven bevel gears 9 drive the lead screw 8 to rotate. Since the lead screw 8 is threadedly connected to the moving rod 4, the moving rod 4 moves. The moving rod 4 drives another support rod 1 to move, thereby adjusting the distance between the two support rods 1, which adjusts the overall width of the entire warning device. While the moving rod 4 moves, the moving rod 4 drives the limiting block 11 to move along the limiting groove 12, thereby limiting the moving rod 4 and preventing the moving rod 4 from detaching from the limiting shell 3. Warning light 2 illuminates to provide a warning. The warning sign 22 is inserted into the mounting frame 21 from one end. The screw 23 is rotated; since the screw 23 is threaded into the mounting frame 21, it rotates and moves simultaneously. The screw 23 drives the pressing plate 24 downwards, which in turn drives multiple fixing rods 25 downwards, causing one end of each fixing rod 25 to be inserted into the warning sign 22, thus securing the warning sign 22. Warning signs are displayed on the warning sign 22 to provide a warning.

[0030] Please see Figures 1-5As an embodiment for preventing tipping of the entire device: the support rod 1 is provided with mounting grooves 13 on both sides, and mounting seats 14 are movably provided in the mounting grooves 13. A support leg 15 is fixedly provided on one side of the mounting seat 14. The support rod 1 is provided with fixing chambers 16 on both sides, and insert rods 17 are movably provided in the fixing chambers 16. A push ring 18 is fixedly provided on the insert rod 17. A spring 19 is movably provided between the push ring 18 and the fixing chamber 16. The spring 19 is movably sleeved on the outside of the insert rod 17. One end of the insert rod 17 passes through the fixing chamber 16 and is inserted into the mounting seat 14. The other end of the insert rod 17 extends to the outside of the fixing chamber 16 and is fixedly provided with a handle 20.

[0031] More specifically, when it is necessary to add the anti-tipping function to the entire warning device, pull the handle 20. The handle 20 drives the insertion rod 17 and the push ring 18 to move, the spring 19 is compressed, and the support leg 15 moves, so that the support leg 15 drives the mounting seat 14 to insert into the mounting groove 13. Release the handle 20, and under the push of the spring 19, the push ring 18 drives the insertion rod 17 to move. One end of the insertion rod 17 will be inserted into the mounting seat 14, thereby fixing the mounting seat 14 into the mounting groove 13, thus fixing the support leg 15. One end of the support leg 15 contacts the ground, thereby providing anti-tipping support for the entire device.

[0032] In summary, when the entire device is in use or operation: When the entire warning device is used at a highway construction site and its width needs to be adjusted, turn the handle 7. The handle 7 drives the rotating rod 6 to rotate, and the rotating rod 6 drives multiple driving bevel gears 10 to rotate. Since the driving bevel gears 10 are meshed with the driven bevel gears 9, the multiple driven bevel gears 9 rotate simultaneously. The driven bevel gears 9 drive the lead screw 8 to rotate. Since the lead screw 8 is threadedly connected to the moving rod 4, the moving rod 4 moves. The moving rod 4 drives another support rod 1 to move, thereby adjusting the distance between the two support rods 1, which adjusts the overall width of the entire warning device. While the moving rod 4 moves, the moving rod 4 drives the limiting block 11 to move along the limiting groove 12, thereby limiting the moving rod 4 and preventing the moving rod 4 from detaching from the limiting shell 3. Warning light 2 illuminates to provide a warning. The warning sign 22 is inserted into the mounting frame 21 from one end. The screw 23 is rotated; since the screw 23 is threaded into the mounting frame 21, it rotates and moves simultaneously. The screw 23 drives the pressing plate 24 downwards, which in turn drives multiple fixing rods 25 downwards, causing one end of each fixing rod 25 to be inserted into the warning sign 22, thus securing the warning sign 22. Warning signs are displayed on the warning sign 22 to provide a warning.

[0033] When the anti-tipping function of the entire warning device needs to be added, pull the handle 20. The handle 20 drives the insert rod 17 and the push ring 18 to move, the spring 19 is compressed, and the support leg 15 moves, so that the support leg 15 drives the mounting seat 14 to insert into the mounting groove 13. Release the handle 20. Under the push of the spring 19, the push ring 18 drives the insert rod 17 to move. One end of the insert rod 17 will be inserted into the mounting seat 14, thereby fixing the mounting seat 14 into the mounting groove 13, thus fixing the support leg 15. One end of the support leg 15 contacts the ground, thereby providing anti-tipping support for the entire device.

[0034] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
