| 中文摘要: |
| To ensure the safe operation of the ship lock and improve the efficiency of ship passage,it is necessary to install collision prevention devices in front of the ship lock gate.In response to the problems of short braking distance,high demand for braking force,and high cost of traditional hydraulic buffering anti-collision devices,we design and manufacture a new type of gravity energy dissipation anti-collision device for ship lock gate,and conduct on-site anti-collision tests.Then we analyze the entire process of colliding with the blocking cable at the maximum allowable entry speed of 0.6 m/s for the design ship type of Changzhou fourth line ship lock under a full load of 3,000 t.The results show that the braking distance of the ship during the collision is 12.8 m,and the total height of the counterweight lifting is 2.23 m,both within the design allowable range.The pulling force of the blocking cable and the pulling force of the front drum do not exceed their ultimate tensile strength,which verify the effectiveness of the device in blocking the ship.This anti-collision device can effectively resist the impact of ships,protect the ship lock gates,and has the characteristics of meeting large water level fluctuations,simple mechanism,and easy maintenance. |
