Description

Technical Field

[0001] The utility model relates to the technical field of highway bridges, in particular to a highway bridge travel limiting device. Background Art

[0002] At present, there are more and more private cars and large transport vehicles on the road, but many roads and bridges were built a long time ago. Therefore, it is necessary to restrict the use of super-high and large vehicles to prevent damage to the road surface and bridges, thereby causing the risk of injury to people. Many urban areas do not allow large transport vehicles to pass through, and super-high vehicles are also prohibited from entering the urban area to prevent the risk of street lights and other lower buildings in the urban area being damaged by super-high vehicles. Therefore, traffic restrictions will be set up at the entrances of roads and bridges.

[0003] In the existing highway bridge restriction device, such as the Chinese patent announcement number CN217579884U, a highway bridge restriction device is disclosed, including a height limit pole, a green indicator light, a red indicator light, an infrared distance sensor, a control mechanism, the control mechanism and the green indicator light, the red indicator light, and the infrared distance sensor are all electrically connected, and a speed bump is provided in front of the height limit pole, and a pressure sensor is installed in the speed bump, and the pressure sensor is electrically connected to the infrared distance sensor. The above device can effectively protect the infrared distance sensor, but it is impossible to adjust the height of the restriction under special circumstances. In other words, the existing highway bridge restriction device has a relatively simple function, and it is impossible to limit the height while restricting the traffic. Over-height vehicles are usually overloaded vehicles, which are more dangerous. The traditional height restriction is to limit the height by fixing columns on both sides of the road, and fixing the height limit pole on the upper end of the column, so as to restrict the traffic of super-high vehicles. Although this restriction method plays a role in limiting the traffic, it is impossible for rescue vehicles and urban construction vehicles seeking help to pass through, and the height of the restriction cannot be adjusted under special circumstances.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0029] Embodiment 1

[0030] As described in the background technology, the existing highway bridge restriction device has a relatively simple function and cannot restrict the height while restricting the traffic. Figure 1-4 As shown, in this embodiment, a highway bridge restriction device is provided, comprising:

[0031] The n-type frame 1, the first mounting frame 3 and the second mounting frame 18, wherein the second mounting frame is fixedly mounted on the lower surface of the top end of the n-type frame;

[0032] like Figure 2As shown, a first T-shaped frame 6 is fixedly connected to the lower surface of the first mounting frame 3, a second T-shaped frame 7 is installed at the bottom end of the first T-shaped frame 6, a first push plate 23 is installed on the inner wall of the first T-shaped frame, a second push plate 8 is installed on the inner wall of the second T-shaped frame, a first rack 9 is arranged on the upper surface of one end and the lower surface of the other end of the first push plate, a second rack 24 is arranged on the upper surface of one end and the lower surface of the other end of the second push plate, a first gear 25 is meshedly connected to the teeth of the first rack on the upper surface, a second gear 26 is meshedly connected to the teeth of the first rack on the lower surface, a third gear 27 is meshedly connected to the teeth of the second rack on the upper surface, and a third gear 28 is meshedly connected to the teeth of the second rack on the lower surface. The fourth gear 28 is meshed with the teeth of the second rack on the surface, the first gear and the third gear are fixedly connected to the outer walls of the first rotating plate 29, the two first rotating plates are rotatably connected, the second gear and the fourth gear are fixedly connected to the outer walls of the second rotating plate 11, the two second rotating plates are rotatably connected, an increasing block 12 is fixedly connected between the third gear and the first rotating plate and between the fourth gear and the second rotating plate, the increasing block 12 can make the height of the lower end of the first rotating plate 29 and the height of the top end of the second rotating plate 11 consistent, so as to facilitate the movement of the first rotating plate 29 and the second rotating plate 11, and a pushing mechanism is fixedly connected to the outer wall surface of the first T-shaped frame.

[0033] In this embodiment, the first gear 25 and the second gear 26 are rotatably connected to the outer wall of the first T-shaped frame 6, and the third gear 27 and the fourth gear 28 are rotatably connected to the outer wall of the second T-shaped frame 7. The inner wall of the first installation frame 3 is fixedly connected to the rotating shaft 4, and the outer wall of the rotating shaft is rotatably connected to the coil 5, and as shown in FIG. Figure 1 As shown, one end of the coil 5 is fixedly connected to the bottom front end of the second T-shaped frame 7, wherein the coil 5 is made of flexible material, and a clockwork spring is installed between the rotating shaft 4 and the coil 5, so that the coil 5 can cooperate with the second T-shaped frame 7 to extend and retract.

[0034] like Figure 3 As shown, the pushing mechanism includes a second fixed plate 13, the top of the second fixed plate is fixedly connected to the lower surface of the top of the first T-shaped frame 6, a hydraulic rod 16 is fixedly connected to one side of the second fixed plate, the output end of the hydraulic rod is fixedly connected to a pushing block 15, and a pushing groove 17 is provided inside the first T-shaped frame, a third fixed plate 14 is installed inside the pushing groove, the surface of the third fixed plate is fixedly connected to the surface of the first pushing plate 23, and the outer wall of the pushing block 15 is fixedly connected to the outer wall of the third fixed plate 14. Specifically: the pushing block 15 is driven by the reciprocating motion of the hydraulic rod 16 on the second fixed plate 13, and then the third fixed plate 14 is driven to move in the pushing groove 17, so that the first pushing plate 23 above can be driven to reciprocate.

[0035] Specifically: the first push plate 23 above is pushed to reciprocate by the pushing mechanism, and the movement of the first push plate 23 drives the first gear 25 and the second gear 26 above to rotate through the first racks 9 at both ends, so that the first rotating plate 29 connected to the first gear and the second rotating plate 11 connected to the second gear can be made to rotate with the connection point of the first T-frame 6 as the axis, so that the second push plate 8 can be pushed to rotate with the connection point of the second T-frame 7 as the axis, and the third gear and the fourth gear can be realized.

At the same time, the component below the pushing shaft 22 is rotated with the pushing shaft 22 as the axis, which can effectively avoid damage to the limiting device. After the over-height vehicle passes, the spring 19 loses pressure and returns to its initial state, which can reset the component below the pushing shaft 22.
