摘 要:为保证船闸安全运转、提高船舶过闸效率,有必要在闸门前设置防撞装置。针对传统液压缓冲防撞装置制动距离短、制动力需求大、成本高等问题,设计制作新型船闸闸门重力消能式防撞装置,并进行现场防撞试验。对长洲四线船闸设计船型3000 t满载的工况下,以允许的最大进闸速度0.6 m s碰撞阻拦索的全过程进行分析。结果表明,碰撞过程中船舶制动距离为12.8 m,配重提升总高度为2.23 m,均在设计容许范围内,阻拦索拉力、前端卷筒拉力未超过其极限抗拉强度,验证了该装置在阻拦船舶过程中的有效性。该防撞装置能有效抵挡船舶的撞击,保护船闸闸门,具有满足水位变幅大、机构简单、易于维护等特点。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.
