Description

Technical Field

[0001] This utility model relates to the field of road height restriction technology, specifically a road height restriction device. Background Technology

[0002] With the rapid pace of urban construction, there are more and more overpasses and tunnels in the city. However, traffic protection measures on urban roads are far from meeting the requirements. For example, bridge and tunnel entrances are often hit by oversized vehicles. In order to prevent oversized vehicles from damaging bridges and tunnels, height restriction devices are often installed at both ends of certain road sections after road construction, due to poor road conditions and bridge load limitations, to restrict vehicles of a certain height from passing through the section. However, existing road height restriction devices are usually integrated structures, and it is inconvenient to adjust the height of the height restriction bar after installation. As a result, paving vehicles cannot enter the road during later maintenance and reconstruction, and the height restriction device needs to be removed and rebuilt, resulting in waste of resources and reduced practicality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figs. 1-3 This utility model provides a technical solution: a road height restriction device, including a height restriction sign 1, a height restriction pole 2 on the back of the height restriction sign 1, an mounting plate 3 on the outer surface of the height restriction pole 2, and first bolts 4 inserted at the four corners of the back of the mounting plate 3. The mounting plate 3 and the first bolts 4 facilitate the installation and removal of the height restriction sign 1, and the replacement of the height restriction sign 1 with different height restriction values. The device is easy to operate and convenient for personnel to replace. A lifting rod 5 is welded to the left and right ends of the height restriction pole 2. A support cylinder 6 is fitted onto the outer surface of the lifting rod 5, and a second bolt 7 is inserted into the outer surface of the support cylinder 6. The height of the lifting rod 5 can be adjusted by the interaction of the lifting rod 5, the support cylinder 6, and the second bolt 7. During subsequent maintenance and road reconstruction, the height of the height restriction sign 1 and the height restriction pole 2 can be adjusted to allow transport vehicles to pass. Furthermore, the connection between the lifting rod 5 and the support cylinder 6 is not integral, making disassembly and installation relatively simple, reducing the time required for installation and disassembly, and facilitating user operation.

[0023] In order to improve the practicality of the device, the front of the height limit sign 1 is painted with alternating yellow and black paint to facilitate the observation of the height limit value on the height limit sign 1. The thickness of the mounting plate 3 is the same as the thickness of the height limit sign 1 to maintain the load-bearing capacity of the mounting plate 3 on the height limit sign 1, so that the height limit sign 1 is more firmly placed on the height limit rod 2. The outer surface of the lifting rod 5 is provided with a fixing groove for the insertion of the second bolt 7, so that the lifting rod 5 can be fixed in the support cylinder 6. The spacing between the multiple sets of fixing grooves is fifty millimeters, so that the range of motion of the height limit sign 1 is a multiple of five. The edges of the outer surface of the support plate 8 are rounded, and the radius of the rounded edge of the outer surface of the support plate 8 is ten millimeters, which can prevent personnel from bumping into the edges of the outer surface of the support plate 8 during installation.

[0024] Please see Figs. 1-3 Support plates 8 are welded to the front and rear sides of the outer surface of the support cylinder 6. The support plates 8 increase the support range of the support cylinder 6, allowing the height restriction device to be more stably installed on the road under construction, thus improving the height restriction effect of the device. Two sets of reinforcing plates 9 are welded to the upper surface of the support plate 8. The reinforcing plates 9 make the connection between the bottom structures of the height restriction device more secure, better supporting the height restriction sign 1 and the height restriction pole 2, and improving the display effect of the height restriction value of the height restriction sign 1. A rod 10 is inserted into the upper surface of the support plate 8. A plug 11 is welded to the bottom end of the rod 10, and a third bolt 12 is inserted into the top end of the rod 10. A limiting ring 13 is fitted on the outer surface of the third bolt 12. The rod 10, plug 11, third bolt 12 and limiting ring 13 make the connection between the height restriction device and the ground more secure. When a vehicle runs through the checkpoint, it can stop the over-height vehicle, prevent the vehicle from damaging the road, and maintain the height restriction effect of the device.

[0025] The upper surface of the support plate 8 is provided with a splicing groove 14, and a protective cover 15 is inserted inside the splicing groove 14. The splicing groove 14 and the protective cover 15 can protect the installation location of the third bolt 12, prevent wind and sand from filling the space between the third bolt 12 and the support plate 8, and reduce the impact on personnel when disassembling and assembling the height limit device. The outer surface of the insertion rod 10 is provided with a cylindrical groove 16. Through the cylindrical groove 16, when personnel disassemble the insertion rod 10 and the plug 11, a tool can be inserted through the insertion rod 10, which allows the staff to lift the insertion rod 10 with less effort and makes it easier for personnel to use.

[0026] In order to improve the compactness of the connection between the structures of the device in this utility model, the reinforcing plate 9 is set as a right-angled triangle plate. The inner side of the reinforcing plate 9 is welded to the outer surface of the support cylinder 6, so that the connection between the support cylinder 6 and the support plate 8 is more firm. The outer diameter of the limiting ring 13 is the same as the inner diameter of the splicing groove 14. The outer surface of the limiting ring 13 contacts the inner wall of the protective cover 15, so that the protective cover 15 can cover the limiting ring 13 and the third bolt 12.

[0027] In use, the device is transported to the road construction site where height restrictions are required. The support cylinder 6 is placed on the ground, and the plug 11 is inserted into the ground through the support plate 8. The plug rod 10 is hammered to make its top flush with the upper surface of the support plate 8. The limiting ring 13 is placed on the third bolt 12, and the third bolt 12 is screwed into the plug rod 10. The protective cover 15 is inserted into the splicing groove 14 to cover the limiting ring 13 and the third bolt 12. The lifting rod 5 is inserted into the support cylinder 6, and the second bolt 7 is screwed into the lifting rod 5 through the support cylinder 6 to fix the lifting rod 5. The height restriction value is sprayed on the height restriction sign 1. The height restriction sign 1 is brought into contact with the height restriction rod 2, and the mounting plate 3 is placed on the height restriction rod 2. The first bolt 4 is screwed into the height restriction sign 1 through the mounting plate 3 to fix the height restriction sign 1, thus completing the installation of the height restriction device.

[0028] In summary, this road height restriction device, through the cooperation of the lifting rod 5, the support cylinder 6, and the second bolt 7, allows for adjustment of the height of the lifting rod 5. During subsequent maintenance and road reconstruction, the heights of the height restriction sign 1 and the height restriction rod 2 can be adjusted to allow transport vehicles to pass. Furthermore, the connection between the lifting rod 5 and the support cylinder 6 is not integral, making disassembly and installation relatively simple, thus shortening the time required for personnel to install and disassemble, and facilitating personnel use. The installation plate 3 and the first bolt 4 facilitate the installation and disassembly of the height restriction sign 1, and make it easy to replace the height restriction sign 1 with different height restriction values. The operation is simple and easy for personnel to replace.

[0029] The road height restriction device, through the installation of support plate 8, can increase the support range of support cylinder 6, enabling the height restriction device to be more stably installed on the road under construction, thus improving the height restriction effect of the device. Through the installation of reinforcement plate 9, the connection between the bottom structure of the height restriction device is more solid, which can better support the height restriction sign 1 and the height restriction pole 2, and improve the display effect of the height restriction value of the height restriction sign 1.

[0030] This road height restriction device, through the installation of the insertion rod 10, plug 11, third bolt 12, and limiting ring 13, ensures a more secure connection between the device and the ground. When a vehicle tries to break through the barrier, it can stop oversized vehicles, preventing them from damaging the road and maintaining the height restriction effect. The installation of the third bolt 12 is protected by the splicing groove 14 and the protective cover 15, preventing wind and sand from filling the space between the third bolt 12 and the support plate 8, reducing the impact on personnel when disassembling and assembling the height restriction device. The cylindrical groove 16 allows personnel to easily lift the insertion rod 10 by inserting a tool through it when disassembling the insertion rod 10 and plug 11, making it convenient for personnel to use.
