The anti-ship collision device of a kind of bridge main dynamic formula
Technical field
What the present invention relates to is a kind of bridge protection device, specifically the anti-ship collision device of a kind of bridge pier, and what more specifically relate to is the anti-ship collision device of a kind of bridge main dynamic formula.
Background technology
At present, the rise of building along with domestic large span bridge, the risk of Ship-Bridge collision can not be ignored.The traditional axle ship anticollision device, collision-prevention device decorum can be divided into: passive anticollision device, collision-prevention device system and active anti-collision device system.Widely used is at present passive anticollision device, collision-prevention device system, but the immutable form of passive anticollision device, collision-prevention device system, and then inevitably bring occupy navigation region, affect the problems such as bridge is attractive in appearance.And early warning can not guarantee that boats and ships successfully correct navigation channel and avoid bridge, prevent from clashing into after active collision-avoidance system is used for DEVIATION at present.
Therefore now the anti-ship collision device of a kind of bridge main dynamic formula that can solve the problem is needed, can effective solving practical problems.
Summary of the invention
The object of the present invention is to provide one can solve existing anticollision device, collision-prevention device and occupy navigation region, anti-collision energy absorption effect is undesirable, cannot prevent fore from thrusting the anti-ship collision device of bridge main dynamic formula of the problems such as wound.
The object of the present invention is achieved like this:
Comprise the pole being fixedly mounted on the bridge pier left and right sides, be provided with spring bumper in the middle of described pole, the described pole other end is connected with the axis of rolling, and the described axis of rolling is connected with apron.
Bridge pier each side arranges 3-5 root pole, and the length of every root pole is equal, and the pole being positioned at outside is that certain angle makes the curved distribution of each axis of rolling relative to being positioned at middle pole.
Described spring bumper is made up of spring and rubber protecting sheathing.
The invention solves existing anticollision device, collision-prevention device in the design of civil engineering bridge-collision-avoidance and occupy navigation region, anti-collision energy absorption effect is undesirable, cannot prevent fore from thrusting and hinder problem.Its beneficial effect:
(1) structure of the present invention is simple, and structure rationally;
(2) initiatively the collision thing tractions such as hull can be escaped the danger of clashing into bridge pier;
(3) anti-collision energy absorption is satisfactory for result.
Accompanying drawing explanation
Fig. 1 is invention structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing citing, the present invention is described in more detail.
The anti-ship collision device of a kind of bridge main dynamic formula, comprise bridge pier 1, pole 2, spring bumper 3, the axis of rolling 4, apron 5, described bridge pier about 1 two ends are connected with pole 2 one end, are provided with spring bumper 3 in the middle of pole 2, the other end is connected with the axis of rolling 4, and the axis of rolling 4 is connected with apron 5.
The number of described pole 2 is 6 ~ 10, and length is 30 ~ 80 centimetres.
Described spring bumper 3 is made up of spring and rubber protecting sheathing, and the number of spring bumper 3 is 6 ~ 10, and length is 30 ~ 50 centimetres.
The diameter of the described axis of rolling 4 is 10 ~ 30 centimetres.
The thickness of described apron 5 is 1 ~ 3 centimetre.
As shown in Figure 1, when other collision things such as having hull clash into bridge pier 1, will contact apron 5, the axis of rolling 4 that apron 5 connects rotates, and has spring bumper 3 to carry out colliding the buffering of thing, reduces impact.Now, collision thing will be walked around along bridge pier 1, effectively prevents ship from hitting danger.
