The embodiment of the invention provides a hydraulic system, maintenance operation equipment and a maintenance system, and belongs to the technical field of maintenance operation. The hydraulic system comprises an active amplitude variation cylinder, at least one active leveling cylinder and at least one passive leveling cylinder, wherein a rod cavity of each passive leveling cylinder is selectively communicated with a rod cavity of the active leveling cylinder, a rodless cavity of each passive leveling cylinder is selectively communicated with a rodless cavity of the active leveling cylinder, and the sum of the sectional areas of the rod cavities of all the active leveling cylinders is smaller than the sum of the sectional areas of the rod cavities of all the passive leveling cylinders. The sum of the sectional areas of the rodless cavities of all the active leveling cylinders is smaller than the sum of the sectional areas of the rodless cavities of all the passive leveling cylinders, so that the telescopic speed of the passive leveling cylinders is smaller than that of the active leveling cylinders; the active leveling cylinder and an active amplitude variation cylinder move synchronously, and the passive leveling cylinder and the active leveling cylinder move synchronously. And by shortening the stroke and the total length of the passive leveling cylinder, miniaturization of maintenance operation equipment is facilitated.

    本申请实施例提供一种液压系统、检修作业设备以及检修系统,属于检修作业技术领域,包括主动变幅缸、至少一个主动调平缸以及至少一个被动调平缸。每个被动调平缸的有杆腔与主动调平缸的有杆腔选择性地连通,每个被动调平缸的无杆腔与主动调平缸的无杆腔选择性地连通,所有主动调平缸的有杆腔的截面积之和小于所有被动调平缸的有杆腔的截面积之和,所有主动调平缸的无杆腔的截面积之和小于所有被动调平缸的无杆腔的截面积之和,以使被动调平缸的伸缩速率小于主动调平缸的伸缩速率;主动调平缸与主动变幅缸同步运动,被动调平缸与主动调平缸同步运动。通过缩短被动调平缸的行程和总长度,有利于检修作业设备小型化。
