Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
As shown in Figure 1, a kind of bridge anti-collision safety system, is vertically arranged in the hollow of 1 two sides of bridge floor including several
Cylindrical anticollision cylinder 2, the bottom surface of anticollision cylinder 2 is parallel with bridge floor 1, and each anticollision cylinder 2 passes through an attachment device 3
It is rotatablely connected with bridge floor 1；
As shown in Fig. 2, being provided with the rotation support column 21 of hollow cylinder in anticollision cylinder 2, rotating support column 21 and preventing
The coaxially arranged of cylinder 2 is collided, rotation support column 21 runs through and is rotatablely connected with the upper bottom surface of anticollision cylinder 2.
Be additionally provided with several anticollision cylinder support bars 22 in anticollision cylinder 2, at least one end of anticollision cylinder support bar 22 with
2 inner wall of anticollision cylinder or rotation 21 outer wall of support column connection.
As shown in figure 3, attachment device 3 includes the first rotation axis 31 being rotatablely connected with rotation support column 21, the first rotation
Axis 31 is also rotatablely connected with connecting cylinder 32, and connecting cylinder 32 is also rotatablely connected with the second rotation axis 33, the second rotation axis 31 and bridge floor 1
Rotation connection.
Connecting cylinder groove 36 is provided on connecting cylinder 32；Attachment device 3 further includes connecting rod 34, and one end of connecting rod 34 is stretched
Enter to connecting cylinder groove 36；Attachment device 3 further includes the third transmission shaft 35 through connecting cylinder groove 36, third transmission shaft 35
It is rotatablely connected respectively with connecting cylinder 32, connecting rod 34, the other end of connecting rod 34 and the first rotation axis 31 are rotatablely connected.
Connecting cylinder 32 is rotatablely connected by first bearing and the second rotation axis 33；Third transmission shaft 35 by second bearing with
Connecting cylinder 32；The other end of connecting rod 34 is rotatablely connected by 3rd bearing and the first rotation axis 31.
First bearing, second bearing are all made of two-way damping bearing in 3rd bearing, so no matter anticollision cylinder from which
Impact of a direction by accident vehicle, damping bearing can play buffer function.
As shown in figure 4, the both ends of anticollision cylinder support bar 22 are respectively and in rotation 21 outer wall of support column and anticollision cylinder 2
Wall abuts.The structure of this monoblock type improves the convenience of the present apparatus during installation.
The present invention can also be used 22 one end of anticollision cylinder support bar with rotation 21 outer wall of support column connect and the other end with prevent
Collision 2 inner wall of cylinder abuts against or 22 one end of anticollision cylinder support bar is connected with 2 inner wall of anticollision cylinder and the other end and rotation are propped up
The scheme that dagger 21 abuts against when using both above-mentioned schemes, increases the level that whole device can be rotated mutually, improves
The ability of damping energy-absorbing, while being also required to bigger technology difficulty；In the retentivity of whole device, globality and energy-absorbing bradyseism energy
Certain balance is obtained between power.
The present invention, which also exploits, uses anticollision cylinder support bar 22 only one end and rotation 21 outer wall of support column or 2 inner wall of anticollision cylinder
It is connected.As shown in figure 5,22 one end of anticollision cylinder support bar rotation, 21 outer wall of support column connection, anticollision cylinder support bar 22 are another
The midpoint of one end connecting line between rotation 21 outer wall of support column and 2 inner wall of anticollision cylinder, makes anti-collision in this way
The gradable energy-absorbing bradyseism of cylinder 2 is hit, when impacting smaller, energy is absorbed by the deformation of anticollision cylinder 2, it is first when impacting larger
The deformation for gating anticollision cylinder 2 absorbs energy, then is made by the Double-energy-absorption of anticollision cylinder 2 and anticollision cylinder support bar 22
With absorption impact energy.
Anticollision cylinder support bar 22 is undaform support bar.
Anticollision cylinder 2, rotation support column 21, anticollision cylinder support bar 22 are made of damping material.
Preferably, it as shown in figure 4, the cross section of anticollision cylinder 2 is that circular symmetry intercepts two pieces, is formed and is prevented towards adjacent
A plane of cylinder 2 is collided, can be put in this way when installing anticollision cylinder 2, and anticollision can be increased
Density between cylinder 2 improves the ability that anticollision cylinder 2 absorbs energy.
When a collision occurs, the impact of accident vehicle generates bang to anticollision cylinder 2 first, and deformation occurs for anticollision cylinder 2
And adjacent anticollision cylinder 2 is hit in the rotation of 21 device of relative rotation support column；Its complementary energy is converted into each component in attachment device 3
Between the momentum mutually rotated.
The foregoing is merely a prefered embodiment of the invention, is not intended to limit the invention, all in the spirit and principles in the present invention
Within, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
