When wind power maintenance personnel need to pass between the wind power maintenance personnel and the landing stage, firstly, a handle of the multi-way valve amplitude-variable oil cylinder is operated to lift the landing stage upwards until the landing stage is horizontal; then operating a handle of the multi-way valve slewing device, and rotating the trestle out of the ship board until the trestle is over against the wind power tower; and operating a handle of the multi-way valve telescopic oil cylinder to extend the trestle until a gripper at the head of the trestle collides with the wind-power tower, sending a signal by a pressure sensor on the gripper at the moment, extending a piston rod of the clamping oil cylinder, clamping the wind-power tower by the gripper, automatically starting a wave follow-up function, and enabling the trestle device to be in a floating state and move along with the movement of waves.
The pump station 1 provides power sources for the left and right rotation of the rotating device 3, the stretching of the amplitude-variable oil cylinder 5, the stretching of the stretching oil cylinder 7 and the stretching of the clamping oil cylinder 9. The direction and speed of the four movements are controlled by a multi-way valve 2 mounted on the operating platform. When the trestle device is in a storage state, the turning device rotates the trestle to a storage position, the piston rod of the amplitude-variable oil cylinder retracts, the clamping oil cylinder and the piston rod of the telescopic oil cylinder are also in retraction positions, and the trestle device retracts to the minimum storage size and is stored on a deck.
When a wind power maintainer needs to operate on a wind power tower, the operator operates the variable-amplitude oil cylinder, the rotating device and the telescopic oil cylinder handle on the multi-way valve to clamp the hand grip at the head of the trestle on the wind power tower, the pressure sensor on the hand grip sends a signal at the moment, the electric proportional control module on the multi-way valve for controlling the handle of the clamping oil cylinder is powered on, a piston rod of the clamping oil cylinder extends out, and the hand grip clamps the wind power tower.

The electromagnetic valve DT4 in the amplitude variation valve group is electrified, and the two cavities of the amplitude variation oil cylinder are communicated. If the amplitude variation oil cylinder is driven by waves to have a tendency of rising, a piston rod of the amplitude variation oil cylinder is pulled, hydraulic oil in a rod cavity of the amplitude variation oil cylinder is pressed, the hydraulic oil flows into a rodless cavity from the rod cavity through the solenoid valve DT4, the rodless cavity needs more hydraulic oil due to the area difference of the two cavities, and the hydraulic oil in the oil tank flows into the rodless cavity through a balance valve in the valve bank under the action of atmospheric pressure. If the amplitude variation oil cylinder is driven by waves to have a falling tendency, the piston rod of the amplitude variation oil cylinder is pressed, hydraulic oil in the rodless cavity of the amplitude variation oil cylinder is pressed, the hydraulic oil flows into the rod cavity from the rodless cavity through the solenoid valve DT4, and redundant hydraulic oil flows back to the oil tank through the multi-way valve due to the area difference of the two cavities.
Solenoid valves DT2 and DT3 in the telescopic valve group are electrified, and two cavities of the telescopic oil cylinder are communicated. If the telescopic oil cylinder is driven by waves to have a stretching trend, a piston rod of the telescopic oil cylinder is pulled, hydraulic oil in a rod cavity of the telescopic oil cylinder is pressurized, the hydraulic oil flows into a rodless cavity from the rod cavity through the solenoid valve DT2, more hydraulic oil is needed in the rodless cavity due to the area difference of the two cavities, and the hydraulic oil in the oil tank flows into the rodless cavity through a balance valve in the valve bank under the action of atmospheric pressure. If the telescopic oil cylinder is driven by waves to have a retraction trend, a piston rod of the telescopic oil cylinder is pressed, hydraulic oil in a rodless cavity of the telescopic oil cylinder is pressed, the hydraulic oil flows into a rod cavity from the rodless cavity through the solenoid valve DT2, and redundant hydraulic oil flows back to the oil tank through the solenoid valve DT3 and a multi-way valve due to the area difference of the two cavities.
In the rotary valve group, the electromagnetic valves DT5 and DT6 are electrified, the brake of the rotary device is opened, and two cavities of the rotary device are communicated. If the wave drives the rotating device to rotate, hydraulic oil in one cavity of the rotating device is pressurized, the hydraulic oil flows from one cavity of the rotating device to the other cavity of the rotating device through the solenoid valve DT5, and the hydraulic oil in the oil tank is replenished through the balance valve in the valve bank under the action of atmospheric pressure due to leakage of the rotating device.
