Chimeric completion groove surface and joint face dock.So, by pier anticollision unit spliced into anticollision guard ring it is convenient install with
Dismounting.
Embodiment 3
As shown in figure 4, the anticollision device, collision-prevention device that the anticollision guard ring in a kind of use embodiment 2 is spliced, including the first anticollision
Guard ring 1, the first anticollision guard ring 1 is outer to surround the second anticollision guard ring 2 for having 2 sizes to increase successively, the 3rd anticollision shield successively
Circle 3；Chimeric completion medial surface by groove a and projection A and the connection of lateral surface between the adjacent anticollision guard ring；It is described every
Be located in two adjacent anticollision guard rings the anticollision guard ring of relative internal layer anticollision guard ring of the lateral surface with being located at opposed outer layer it is interior
Side mutually fits.
Above-mentioned anticollision device, collision-prevention device is spliced by anticollision guard ring, and installation and removal are very convenient, when the anticollision guard ring quilt of outer layer
When breaking, the pier anticollision unit of corresponding site need to be only changed, repairs very convenient quick, greatly reduces maintenance cost.And
And, above-mentioned anticollision device, collision-prevention device can also improve intensity and impact resistance by increasing the quantity of anticollision guard ring.
In the present embodiment, the projection A and projection B on the anti-collision unit is the dovetail that end is more than root, institute
It is wedge-shaped groove of the opening less than bottom to state groove a and groove b.So, projection A and groove a can form self-locking structure, together
When, projection B and groove b can form self-locking structure, improve the integrated connection intensity of anticollision device, collision-prevention device, reliable and stable, be difficult to take off
Fall.
In the present embodiment, the projection B in any one described anticollision guard ring and adjacent position on adjacent anticollision guard ring
Projection B's is in opposite direction.So, though due to make adjacent anticollision guard ring occur groove surface and joint emaciated face from pulling force on the contrary,
During larger by certain side pulling force of anticollision device, collision-prevention device, generally speaking it is not easy to disconnect with regard to anticollision device, collision-prevention device, bonding strength is high, it is stable
Reliably.
