Embodiment 1

[0026] as attached figure 1 And attached figure 2 As shown, a floating body limiting device for realizing the floating anti-ship collision floating body limiting method is arranged next to the bridge body 1 and includes a floating body 3 and a blocking limiting device. The blocking limiting device in this embodiment includes anti-collision auxiliary The pier 5 and the steel structure blocking cover 2, the anti-collision auxiliary pier 5 is fixed on the river bed through the floating body 3; the floating body 3 is set on the auxiliary pier 5, and can move vertically up and down along the auxiliary pier 5; There is a stop limit device that restricts the vertical floating of the floating body; the stop limit device is a steel structure stop cover 2 installed on the upper head of the anti-collision auxiliary pier 5, and the present embodiment is provided with 4 anti-collision auxiliary pier 5, the distance A steel structure blocking cover 2 is respectively arranged above the two...

Embodiment 2

[0028] The difference between this embodiment 2 and embodiment 1 is that the blocking device used is different, and this embodiment 2 is as attached image 3 with Figure 4 As shown, below the floating body 3 is provided with a blocking device that restricts the vertical floating of the floating body; the blocking device includes an anti-collision auxiliary pier 5 and a cable 6, and the anti-collision auxiliary pier 5 passes through the floating body and is arranged on the river bed. One end of the cable 6 is fixed on the anti-collision auxiliary pier 5, and the other end is fixed on the floating body 3, and the one-way limit valve 4 is one at each of the left and right ends.

[0029] As a further improved embodiment of this embodiment, the blocking and limiting device is a cable 5 without an anti-collision auxiliary pier, one end of the cable 5 is fixed on the river bed, and the other end is fixed on the floating body.

[0030] In the above embodiments, the floating body...

Abstract

The invention discloses a limiting method and device for a floating type ship collision prevention floating body. The limiting device comprises a floating body and a stop limiting device, wherein the floating body is sleeved on an auxiliary pier, and can move up and down; the upper surface or the lower surface of the floating body is provided with a stop limiting device for limiting the floating body from vertically floating upwards; a one-way limit valve is installed on the floating body; a cavity is formed inside the floating body; and the one-way limit valve is connected to the cavity inside the floating body. Under the effect of the stop limiting valve, the vertical height of the floating body is limited, the floating body is positioned at the highest vertical height permitted by the stop limiting device; if the water level rises continuously, the hydraulic pressure suffered by the surface of the floating body is increased, and when the hydraulic pressure is increased to the pressure set by the one-way limit valve, the one-way limit valve is opened and the water enters into the cavity inside the floating body, the vertical resultant force suffered by the floating body is reduced, and finally the force is balanced at the limit position; and therefore, the defect that a floating-type ship collision prevention floating body brings adverse effects and potential safety hazards to bridges in an extreme water level or a high water level is overcome.

Description

technical field [0001] The invention relates to a bridge protection device, in particular to a method and a device for limiting the position of a floating anti-ship collision floating body. Background technique [0002] At present, with the construction of a large number of bridges in waterway and land transportation, the possibility of ship-bridge collision accidents is also increasing. Once a ship-bridge collision occurs, it is likely to cause a series of serious consequences such as bridge collapse, ship destruction and human death, and environmental pollution. In order to prevent or reduce the damage of the ship collision pier, the application of floating anti-ship collision device is more and more extensive. Under extreme water level conditions, the floating body of the floating anti-ship collision device generates an upward lifting force on the bridge under the action of buoyancy, in addition to the water resistance force. For the ship device at this time, due to the ...
