An air inlet pre-treatment box 28 is arranged at the communication position of the left side wall of the lifting base 6 and the air inlet pipe 20, a U-shaped drying pipe 26 filled with a water absorbing drying agent and an air heater 27 are arranged in the air inlet pre-treatment box 28, when drying operation is carried out after flushing of the inner cavity equipment at the right side of the lifting base 6, a blowing drying mode is adopted, and when blowing drying operation is carried out, water content in air can be reduced by removing water from the air, so that the content of corrosive seawater in the air is reduced, and the air heated by the air heater 27 has a better drying effect when blowing drying is carried out.
Before the invention is used, the hydraulic lifting column 23 is positioned at a low position, the beam loop bar 9 and the movable beam 10 are rotated into the inner cavity of the lifting base 6 through the rotating shaft 8 under the factor of gravity, when the invention is used, the rotary starting wire wheel 11 is firstly started to fold the first steel cable 13, when the first steel cable 13 is in folding motion, the first steel cable 13 connected with the right side of the top of the movable beam 10 drives the movable beam 10 to rotate upwards along the rotating shaft 8, when the bottom of the movable beam 10 is higher than the roller 29 at the top of the hydraulic lifting column 23, the hydraulic lifting column 23 is extended upwards, the roller 29 is connected with the bottom of the movable beam 10, and the upward movement is continued until the beam loop bar 9 and the movable beam 10 reach a horizontal position, wherein in order to prevent the height of the right ends of the beam loop bar 9 and the movable beam 10 from being too high, the limit length of the upward extension of the hydraulic lifting column 23 can be limited, the hydraulic lifting column 23 is in the upper limit extension state, and the lifting beam loop bar 9 and the moving beam 10 are in the horizontal state.
Then, when the hoisting operation is carried out, the driving shaft 4 drives the rotating disc 5 to rotate through the work of the angle adjusting motor 3, so that the direction of the lifting hook at the bottom of the second steel cable 14 is adjusted; the position of the movable cross beam 10 is moved left and right through a telescopic hydraulic push rod 17, and the extending horizontal position of the lifting hook at the bottom of the second steel cable 14 is adjusted, so that objects in different directions and positions can be lifted by the lifting hook within an adjustable range; during the hoisting operation, the hoisting wire wheel 12 can lift the second wire rope 14.
After the lifting operation is completed, the right ends of the beam loop bar 9, the movable beam 10 and the second steel cable 14 are soaked with seawater and absorb some impurities, and the cleaning is needed. Firstly, the hydraulic push rod 17 is shortened, the movable beam 10 moves to the extreme position leftwards, namely the total length of the beam loop bar 9 and the movable beam 10 reaches the minimum value, because no load is hoisted at the moment, the rotary starting wire wheel 11 is kept fixed, the hydraulic lifting column 23 is shortened downwards to the low position, then the rotary starting wire wheel 11 is started, the first steel cable 13 is extended at a constant speed, and under the action of gravity, the beam loop bar 9 and the movable beam 10 are screwed downwards into the right inner cavity of the hoisting base 6 around the rotating shaft 8. Then, a cleaning water source is connected to the water inlet 1802, the water pump 1803 is started, and cleaning water is sprayed out of the cleaning spray head 1806 through the water inlet pipe 1804 and the water outlet pipe 1805 to clean the equipment. After cleaning, the blower 19 and the air heater 27 are started, outside air is sequentially removed through the U-shaped drying pipe 26, the air heater 27 is used for heating, and then the high-pressure air nozzle 21 is used for spraying dry air to dry the equipment, so that the service life of the equipment can be effectively prolonged in a corrosive offshore environment.
