Water depth self-adaptive emergency braking system and method for ship reception chamber of ship lift
The invention discloses a water depth self-adaptive emergency braking system and method for a ship reception chamber of a ship lift. The water depth self-adaptive emergency braking system comprises an electric pump set for providing hydraulic power, and an oil outlet of the electric pump set is connected with a one-way oil filtering valve set through a first one-way valve; an outlet of the one-way oil filter valve group is connected with a first electromagnetic directional valve and a second electromagnetic directional valve in parallel through a second one-way valve, the second electromagnetic directional valve is connected with a speed regulating valve in series, and an outlet of the speed regulating valve is connected with a third electromagnetic directional valve and a proportional overflow valve in parallel; the other ends of the first electromagnetic directional valve and the third electromagnetic directional valve are connected with a working brake; a fourth electromagnetic directional valve is mounted between the working brake and the oil tank; and the system also comprises a PLC (Programmable Logic Controller) for controlling the system. According to the braking system, on the basis that the current of the proportional overflow valve is adjusted to control the braking torque, the unbalanced load generated by mistakenly loading the water depth of the ship reception chamber is considered, the braking torque can be accurately output, and therefore it is guaranteed that the ship reception chamber is emergently braked at the proper acceleration, and mechanical impact or the braking stroke is reduced.
本发明公开了一种升船机承船厢水深自适应紧急制动系统及方法，它包括用于提供液压动力的电动泵组，电动泵组的出油口通过第一单向阀与单向滤油阀组相连；单向滤油阀组的出口通过第二单向阀并联有第一电磁换向阀和第二电磁换向阀，第二电磁换向阀上串联有调速阀，调速阀的出口并联有第三电磁换向阀和比例溢流阀；第一电磁换向阀和第三电磁换向阀的另一端与工作制动器相连；所述工作制动器和油箱之间安装有第四电磁换向阀；还包括用于控制系统的PLC控制器。此制动系统在调节比例溢流阀电流控制制动力矩的基础上，考虑承船厢误载水深产生的不平衡载荷，能够精确输出制动力矩，从而保证承船厢在适合的加速度下紧急制动，减少机械冲击或制动行程。
