Example 1

Referring to fig. 1-3, the embodiment provides a bridge protection device for municipal engineering, including a mounting seat, the mounting seat is fixedly mounted on a bridge, the mounting seat is provided with a fixing column 5, the fixing column 5 is vertically disposed, and both ends of the fixing column are provided with lantern rings 1, the lantern ring 1 is connected with a main support rod 2, one end of the main support rod 2 away from the lantern ring 1 is provided with a secondary support rod 3, a cavity is formed in the main support rod 2, the main support rod 2 and the secondary support rod 3 are slidably sleeved, a buffer structure is further disposed in the main support rod 2, one end of the secondary support rod 3 away from the main support rod 2 is provided with a ring seat, a rotating shaft 4 is disposed in the ring seat, the rotating shaft 4 can rotate around its own axis in the ring seat, the rotating shaft 4 is sleeved with an inner drum 11, the inner drum 11 can rotate on the rotating shaft 4 and is made of rigid material, the outer roller 7 is sleeved outside the inner roller 11, the outer roller 7 is made of a material with elastic characteristics, the profile of the side face of the outer roller 7 is arc-shaped, two main supporting rods 2 extend out of each fixing column 5, each rotating shaft 4 is connected with a secondary supporting rod 3 arranged on two different fixing columns 5, therefore, the rotating shaft 4 and the two fixing columns 5 positioned on the two sides of the rotating shaft are connected through the main supporting rods 2 and the secondary supporting rods 3 to form a triangular structure, the structure is more stable and firm, when a vehicle collides with the device, the vehicle firstly collides with the outer roller 7, the outer roller 7 deforms to absorb energy generated by the collision and decelerate the vehicle, further, a buffer structure arranged in the main supporting rods 2 acts to further buffer and decelerate the inner roller 11 and the outer roller 7 rotate on the rotating shaft 4, and the rotating shaft 4 rotates in the ring seat at the same time, therefore, the direction of the impact force of the vehicle towards the outside of the bridge can be deflected to the direction parallel to the bridge, and the vehicle can be prevented from directly tipping over and flying out of the bridge.

Specifically, buffer structure's chooseing for use does not add the restriction, if can set up the cylinder in the main branch pole 2, and inferior branch pole 3 cup joints in the cylinder while the cylinder keeps certain pressure, so can play the cushioning effect, in this embodiment, preferably, buffer structure is spring 9, spring 9 is thrust spring, so the structure is simpler, and it is more convenient to produce the installation, and the cost is lower.

Specifically, at least one bearing 6 is arranged between the rotating shaft 4 and the ring seat, at least one bearing 6 is arranged between the rotating shaft 4 and the inner roller 11, the selection of the bearing 6 is not limited, in this embodiment, as an example, the bearing 6 is a deep groove ball bearing, the rotation of the rotating shaft 4 and the outer roller 7 is easier and more flexible by arranging the bearing 6, because the core of the device that plays a role in deflecting and guiding the vehicle lies in the rotation of the rotating shaft 4 and the outer roller 7, if the two are blocked in rotation due to a large friction force or other reasons, the situation that the deflection and guiding are not reached due to an excessively high vehicle impact speed may occur, and the upper limit of the speed can be greatly improved by arranging the bearing 6.

Specifically, stress groove 8 has been seted up to outer cylinder 7 side, because stress is great when vehicle device outer cylinder 7, can cause great damage to outer cylinder 7, set up stress groove 8 and can carry out certain release with the stress that the striking produced to prolong the life of outer cylinder 7. The choice of the material with elastic characteristics for processing the outer drum 7 is not limited, and in the present embodiment, the material of the outer drum 7 is, for example, an EVA and polyethylene blend with elastic characteristics.

The working principle of the embodiment is as follows: when a vehicle collides against the device, the vehicle firstly collides with the outer roller 7, the outer roller 7 deforms to absorb energy generated by the collision and decelerates the vehicle, further, the buffer structure arranged in the main support rod 2 acts to further buffer and decelerate the vehicle, meanwhile, the inner roller 11 and the outer roller 7 can rotate on the rotating shaft 4, and the rotating shaft 4 can rotate in the ring seat at the same time, so that the impact force of the vehicle towards the outside of the bridge can be deflected and guided to the direction parallel to the bridge, and the vehicle can be prevented from directly overturning and flying out of the bridge.

Example 2

Referring to fig. 3, the core of the device for deflecting and guiding the vehicle lies in the rotation of the rotating shaft 4 and the outer drum 7, and if the bearing 6 is exposed for a long time, dust can cause the clamping of the bearing, and rain can cause the corrosion of the bearing, which all impair the effect of the device, therefore, on the basis of embodiment 1, the two ends of the inner drum 11 are further provided with dust covers 10, and a rain cover 12 is arranged above the ring seat.
