Specific embodiment
It is fully understood for ease of the public and expert for utility model technical solution, presently in connection with attached drawing to the utility model
It is described in further detail.
As shown in fig. 3 to 7, the embodiment one of a kind of bridge anti-collision device,
Bridge pier 000 is located on cushion cap 001,000 upper end support beam of bridge pier, is bridge floor (Fig. 3 and Fig. 8) above crossbeam,
It can be able to be anchoring piece or built-in fitting in the uniform bracket 410 of 000 upper portion surrounding of bridge pier, bracket, be fixed on bridge pier
Top is by pushing up position.Steel cable 420 is fastened on each bracket, the lower end of steel wire rope 420 is fixed on a round metal
It is set on ring 430, on the metal ring 430 and is additionally provided with eight bolts hole.Prepare eight round steel pipes, and steel tube surface into
Row anti-corrosion treatment, the upper end of steel pipe are fastened on by screw thread and nut in the corresponding bolt hole of metal ring, form eight certainly
Four steel columns 440 of upper and lower lifting.Aforementioned four steel column according to circumstances uses the steel pipe of 50 to 100 millimeters of diameter.Reference chart
2, in the present embodiment, the setting quantity of steel column is eight, is evenly arranged in around bridge pier 000.Certainly the quantity of above-mentioned steel column
It can be 6, four, ten etc..The height of steel column should adapt to the a-hundred-year great flood standard in river.
100 quantity of partly latent case be eight, the structure of eight partly latent casees is identical, by taking the structure of one of partly latent case as an example into
Row explanation.With reference to figure 5 to Fig. 7,100 horizontal section of partly latent case is sector, generally arc body, and partly latent case uses composite material system
Make, specific structure is as follows：
Shell 110 is had and 000 phase of Cylindrical Pier using injection material, the generally arc body of shell 110, shell 110
When radian, a spin mounting groove is set respectively near four angles of inner surface of shell 110, and is pacified in spin mounting groove
111 1 pieces of spin is filled, for spin 111 preferentially using the nylon ball with waterproof antirust function, nylon ball can be certainly in mounting groove
By rotation.When 110 inner surface of shell is fitted on bridge pier, nylon ball rotates so that between partly latent case 100 and bridge pier 000
It is formed and rolls cooperation.Set in the middle position of shell there are one cylindrical perforation 112, for above-mentioned steel column 002 into
Row cooperation, i.e. for partly latent case by being threaded through on above-mentioned steel column, each steel column corresponds to a partly latent case.It will usually wear
The diameter dimension in hole is designed as the diameter slightly larger than steel column, and formation is slidably matched.
In the inside of shell 100 filled with cellular steel ribs 200, hollow processing can also be carried out, steel ribs use
Thickness is that 1 to 2 millimeters of steel plate bending is formed, and is filled in space inside the housing, act as hitting by deforming to absorb
Energy protects bridge pier.Preferential mode, the fold mode of steel ribs 200 ensure optimal with needing the direction of anticollision basically identical
Impact resistance effect, when hit occur when, the deformation that can pass through steel ribs in knockout process absorbs most Impact energy.
Encapsulation order is that steel ribs are filled in shell 110, and carries out the encapsulation of cover plate of outer casing 120, and encapsulation is using heat
Fusion weld.Weld seam is formed, after sweat soldering, percolating water will not occur for long-term (the being usually tener) use of shell.In advance
It is first arranged on cover plate of outer casing 120 and is provided with water irrigating hole 121, for internally pouring water, and lid is set at water irrigating hole.
110 both sides of partly latent case shell are provided with the buckle 113 being used cooperatively and card slot 114, adjacent two after installation
It is formed and is clasped between a partly latent case.The outer surface of partly latent case shell is provided with steel wire rope binding groove 115, for tying
Tie up steel wire rope.Steel wire rope 300 is designed as twice, and after binding, eight partly latent box-shapeds are complete circular into one.
Above-mentioned steel ribs 200 can also be changed to other Energy dissipating materials, such as Energy dissipating material selects polyurethane foam
Foam is filled housing interior volume.
With reference to figure 8, after installation, by controlling the quantity poured water in partly latent case that can control the draft of partly latent case, more
For importantly, this partly latent case can realize automatic adjustment according to the height of the water surface in river, without personnel's intervention, so having
The partly latent case of height adjusting function preferably can carry out security protection to bridge pier.
Embodiment two, as shown in figure 9,
With implement one difference lies in：The length of half tray increases so that has sufficient length.Or in the vertical direction
The superposition of partly latent case is carried out, forms the safeguard procedures of different size.
Embodiment three, with reference to figure 10, with implement one difference lies in：Bridge pier is 400 meters of standard runway patterns, similary suitable
With.
Embodiment described above is only that the preferred embodiment of the utility model is described, not to this practicality
New scope is defined, and on the premise of the spirit of the design of the utility model is not departed from, relevant technical staff in the field is to this
The various modifications of utility model and improvement should all expand as determined by the utility model claims book in protection domain.
