Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a bridge guardrail. Background Art

[0002] Bridge guardrails refer to guardrails installed on bridges. Their purpose is to prevent out-of-control vehicles, pedestrians or cyclists from going over the bridge. They have the function of preventing vehicles from breaking through, passing under or climbing over the bridge, as well as beautifying the bridge structure.

[0003] Bridge guardrails are usually composed of a guardrail frame, a crossbar, and a support beam. The crossbar is inserted into the inner wall of the guardrail frame to shield the edge of the bridge. During installation, the crossbar is usually inserted into the mounting hole reserved on the inner side of the guardrail frame to achieve the installation of the crossbar and the guardrail frame. The crossbar is usually a hollow tube, which is prone to deformation to varying degrees. When the deformation exceeds a certain range, the crossbar needs to be replaced. Because the crossbar is directly inserted into the inner cavity of the mounting hole, it is difficult to remove the crossbar, and it is usually necessary to use external tools to cut the crossbar, which increases the replacement time of the crossbar and increases the difficulty of replacing the crossbar. Utility Model Content

The inner cavity of the placement groove 303 is slidably connected to a cross bar 304. A fixing groove 305 is opened on one side of the connecting plate 302. The inner cavity of the fixing groove 305 is slidably connected to a fixing block 306.

[0025] Reference Figure 1 and Figure 4A first mounting block 4 is fixedly mounted on the surface of the support column 2, a protective plate 5 is provided on the surface of the support column 2, a second mounting block 6 is fixedly mounted on the inner side of the protective plate 5, a spring 7 is fixedly mounted on the surface of the first mounting block 4, one end of the spring 7 is fixedly connected to the surface of the second mounting block 6, and by providing the protective plate 5, damage to the support column 2 can be reduced. When the outside world contacts the protective plate 5, the spring 7 can be pushed to be compressed and approached to the first mounting block 4 due to the fixed connection between the second mounting block 6 and the protective plate 5. The spring 7 is supported by the first mounting block 4, and the force on the support column 2 can be buffered, thereby reducing damage to the support column 2 caused by collision and increasing the service life of the support column 2.

[0026] Reference Figure 2 and Figure 3 The inner wall of the placement groove 303 is provided with a docking groove 9, and a docking block 8 is fixedly installed on one side of the fixed block 306. The surface of the docking block 8 is slidably connected with the inner cavity of the docking groove 9. The sliding connection between the docking block 8 and the docking groove 9 can increase the contact area between the fixed block 306 and the fixed groove 305, increase the stability of the fixed block 306 in the inner cavity of the fixed groove 305, and at the same time, the fixed block 306 enters the fixed groove 305 for docking, so that the fixed block 306 keeps moving horizontally, so that the fixed block 306 can accurately enter the inner cavity of the fixed groove 305;

[0027] Reference Figure 2 A fixing plate 10 is fixedly installed on the other side of the fixing block 306, a dovetail groove 11 is provided at the bottom of the fixing plate 10, a dovetail block 12 is fixedly installed on the top of the fixing plate 10, the inner cavity of the dovetail groove 11 is fixedly connected to the surface of the dovetail block 12, and the dovetail groove 11 is slidably connected to the dovetail block 12. When multiple fixing blocks 306 enter the inner cavity of the fixing groove 305, the bottom of the fixing plate 10 and the dovetail groove 11 will be docked with the dovetail block 12 on the top of the fixing plate 10 on another fixing block 306, so that the adjacent fixing plates 10 are connected, which can increase the stability of the two adjacent fixing blocks 306 after entering the fixing groove 305;

[0028] Reference Figure 3 The inner cavity of the connecting groove 301 is provided with a sliding groove 13, and the inner cavity of the sliding groove 13 is slidably connected to the surface of the fixing plate 10. By providing the sliding groove 13, the sliding groove 13 is slidably connected to the fixing plate 10, so that the connecting groove 301 can be formed into an "L" shape, which can prevent the surface of the fixing block 306 from moving out of the inner cavity of the connecting groove 301, and further increase the stability of the connection between the connecting plate 302, the fixing block 306 and the support column 2;

[0029] Reference Figure 4A support plate 14 is installed on the surface of the support column 2, and the top of the support plate 14 contacts the bottom of the protective plate 5. By providing the support plate 14, the bottom of the protective plate 5 can be supported to prevent the spring 7 from being deformed under the action of the gravity of the protective plate 5, thereby increasing the service life of the spring 7;

[0030] Reference Figure 1 and Figure 4 A card slot 15 is provided at the top of the support column 2, and a card plate 16 is slidably connected to the inner cavity of the card slot 15, and a fixing rod 17 is rotatably connected to the inner wall of the card plate 16, and the surface of the fixing rod 17 is threadedly connected to the inner wall of the support column 2. Through the sliding connection between the card slot 15 and the card plate 16, the opening of the connecting groove 301 opened on the top of the support plate 14 can be blocked, and at the same time, the position of the connecting plate 302 entering the inner cavity of the connecting groove 301 can be fixed to prevent the connecting plate 302 from shaking in the inner cavity of the connecting groove 301. The position of the card plate 16 is further fixed by the fixing rod 17, which can prevent the card plate 16 from moving out of the inner cavity of the card slot 15.

[0031] Working principle: When installing the guardrail, first fix the support column 2 on the bridge deck 1, insert the two ends of the cross bar 304 into the inner cavity of the placement groove 303, and when the cross bar 304 enters the inner cavity of the connecting groove 301, the fixing block 306 enters the inner cavity of the fixing groove 305, and the cross bar 304 can be fixedly installed inside the connecting plate 302, so that the position of the connecting plate 302 and the cross bar 304 is fixed, and the connecting plate 302 enters the inner cavity of the connecting groove 301, completing the splicing between the support column 2 and the cross bar 304. When the cross bar 304 is deformed and needs to be replaced During replacement, the connecting plate 302 is moved out of the inner cavity of the connecting groove 301, and the fixing block 306 that contacts the surface of the deformed cross bar 304 is moved, so that the fixing block 306 is disconnected from the inner cavity of the fixing groove 305, and the deformed cross bar 304 can be taken out, so that the deformed cross bar 304 can be quickly taken out and replaced. After replacement, the fixing block 306 is re-entered into the inner cavity of the fixing groove 305, and the connecting plate 302 is re-entered into the inner cavity of the connecting groove 301, so that the protective effect of the guardrail can be quickly realized, the user's replacement time for the cross bar 304 is reduced, and the replacement efficiency is increased.
