Description

TECHNICAL FIELD

[0001] The application relates to a road-bridge anti-collision protection device for road-bridge design. BACKGROUND

[0002] With the rapid development of traffic infrastructure, the safety and stability of road bridges, which are key channels connecting various places, are increasingly valued. With the increasing number of vehicles and the increasing number of trips, the risk of vehicle collision with road bridges also increases, which not only causes damage to vehicles but also causes serious damage to the structure of the bridge, leading to road bridge collapse, personnel casualties and greater economic losses.

[0003] At present, protective plates are mainly used to protect road bridges. Due to the uneven surface of the vehicle, the contact area of the protection device with the vehicle is small when the protection device contacts the vehicle, and the stress is large, so that the collision energy cannot be fully absorbed, the instantaneous energy of the vehicle and the protection device is increased, and the protection device and the vehicle are easily damaged. To solve the above problems, we propose a road-bridge anti-collision protection device. CONTENT OF THE UTILITY MODEL

[0007] Preferably, a stabilizing plate is slidably connected to the outer surface of each connecting column, and the bottom surface of the stabilizing plate is connected to the upper surface of the bottom plate.

[0008] Preferably, a group of reflective stickers are fixedly connected to the right side of the stabilizing plate, and a warning light is fixedly installed on the upper surface of the stabilizing plate.

[0009] Preferably, the upper surface of the fixed plate is fixedly connected with a rain baffle, and the upper surface of the rain baffle is fixedly connected with a group of solar panels.

[0010] Preferably, the left side surface of the fixed plate is fixedly connected with a battery.

[0011] Preferably, the upper surface of the bottom plate is fixedly connected with two support columns, and the left side surface of the fixed plate is connected with the right side surface of each support column.

[0012] Preferably, the outer surface of the bottom plate is fixedly connected with two handles, and the upper surface of the bottom plate is provided with four mounting holes.

[0013] The above-mentioned at least one technical solution adopted by the embodiment of the application can achieve the following beneficial effects:

[0014] Firstly, the pulley is in contact with the vehicle, and the impact force makes the triangular plate rotate around the first connecting shaft, thereby increasing the contact number and contact area of the pulley with the vehicle; under the action of the impact force, the connecting column moves to the left, and the spring contracts, thereby reducing the instantaneous energy received by the vehicle and the protective device.

[0015] Secondly, part of the impact force is transmitted to the buffer plate when the spring contracts, so that the buffer plate moves to the left on the slide rail, and each buffer simultaneously reduces the impact energy of the buffer plate, so that the collision energy of the vehicle and the road bridge can be fully absorbed, thereby protecting the road bridge and the vehicle.
