Abstract:The traditional linear type ship blocking facilities are not strong in respect of interception ability, and it is easy to damage and difficult to repair after suffering ship collision. In addition,the tension degree of steel rope to intercept the river is not easy to control when the water level variation range is large. In order to solve the above practical engineering problems, this paper uses Gaogang sluice gate station of Taizhou Yinjiang Canal as example to make study of the tidal river sluice gate station friction type ship blocking facilities, conducts the corresponding mechanics calculation, and introduces the design of tensioning device which can keep the ship blocking facilities adapt to water level changes. The calculation results show that the ship blocking facility with belt tension function is feasible, which is designed based on the model that the ship which impact the wire rope is a plane linear motion and the impact point is at the midpoint of wire rope.The research achievements can guarantee that the wire rope will implement progressive force interception to ships when the ship hit the wire rope, which can ensure that the ship hits the wire rope without damage and facilitates her itself-help as well as the function of intercepting facilities returning to normal. Hammer type constant tension tensioning system can make the ship stopped facilities adapt themselves to the change of the tidal river water level, so that the wire rope can keep at a good tension standby state. It is significant for the safety of the tidal zone sluice gate station engineering and passing ships.
