The invention relates to the technical field of compensation equipment, and discloses a hydraulic cylinder for a trailing suction dredger wave compensator. The hydraulic cylinder comprises a winch, and a first hydraulic cylinder is fixedly mounted at the position, on one side of the winch, of a dredger body. According to the hydraulic cylinder for the trailing suction dredger wave compensator, the internal pressure of an energy accumulator connected with the first hydraulic cylinder is larger than that of an energy accumulator connected with a second hydraulic cylinder, a plunger rod in the first hydraulic cylinder ascends to the topmost portion during stable operation, a plunger rod in the second hydraulic cylinder descends to the bottommost portion during stable operation, thus, when the dredger body ascends and a steel cable is tensioned, the first hydraulic cylinder can descend to control loosening when the tension of the steel cable is increased and has a whole descending loosening stroke, and when the dredger body descends, the second hydraulic cylinder controls tensioning when the tension of the steel cable is reduced and has a whole ascending tensioning stroke, so that the first hydraulic cylinder and the second hydraulic cylinder are matched, the stroke when the dredger body is adjusted to float and sink is increased, and the rake head adjusting stability of the equipment is better.

    本发明涉及补偿设备技术领域,且公开了一种耙吸船波浪补偿器用液压缸,包括绞车,所述绞车的一侧且位于船体上固定安装有液压缸一。该耙吸船波浪补偿器用液压缸,通过连接液压缸一的所述蓄能器内压力大于连接液压缸二的蓄能器内压力,液压缸一内的柱塞杆在平稳运行时上升在最顶部,液压缸二内柱塞杆在平稳运动时下降在最底部,使得船体在上升钢缆拉紧时,液压缸一可以下降来控制钢缆拉力变大时的放松,其具有一整个下降放松的行程,在船体下降时,液压缸二来控制钢缆拉力减少的拉紧,其具有一整个上升拉紧的行程,使得液压缸一与液压缸二的配合,使得调节船体浮沉时的行程增加,设备调节耙头平稳性能更好。
