This invention provides an anti-sway system for a suspended display screen, comprising: a folding display screen suspended in mid-air; a lifting component for moving the folding display screen up and down; a height sensor for acquiring the ground clearance data of the folding display screen; a walking component for synchronously translating the folding display screen; a programmable logic controller (PLC) for obtaining swing length data based on the received ground clearance data; an anti-sway controller for obtaining speed data of the lifting component and the walking component based on the received swing length data and a target speed command, and transmitting the obtained speed data of the lifting component and the walking component to the PLC; and the PLC controlling the speed of the lifting component and the walking component based on the received speed data. This invention can prevent the swaying problem of the folding display screen during high-altitude suspended movement.

The hydraulic walking system comprises an oil tank, an oil supplementing pump, a plunger pump assembly and a motor assembly, the plunger pump assembly comprises a plunger pump and a plunger pump adjusting assembly, the motor assembly comprises a motor and a motor adjusting assembly, the displacement of the plunger pump is controlled through the plunger pump adjusting assembly, and then the rotating speed of the motor is changed. The motor displacement is adjusted through the motor adjusting assembly, and the rotating speed of the motor is further adjusted. According to the hydraulic walking system and the crawler operation machine, parking gear shifting and extra gear shifting operation are not needed during transition acceleration, continuous change of motor displacement is achieved, and therefore stepless speed change of the walking speed is achieved; meanwhile, gear shifting operation in the advancing process is prevented, large pressure change caused by two-point displacement change of the motor in the advancing process is avoided, impact on a control valve set and the motor is reduced, and the service life is prolonged.
