Implementation

[0018] The invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0019] As shown in the figure, an ultra-high pressure water rust removal vehicle and a rust removal method that realize the mechanized operation of ultra-high pressure water rust removal for the entire ship are provided. The ultra-high pressure water rust removal vehicle comprises a body support 1, the body support 1 is equipped with a control box, a lifting device is installed on the body support 1, the lifting device controls the up and down movement of the rust removal head 2 support, the rust removal head 2 support is equipped with the rust removal head 2, an adjusting device is installed between the rust removal head 2 support and the rust removal head 2, the control is realized by the control box, the body support 1 is moved to reach the rust removal destination, the lifting device is controlled to control the rust removal head 2 to move up and down, four adjusting devices are independently controlled by four motors 10, and corresponding adjustments are made according to the inclination of the bottom shell of the ship, so that the rust removal head 2 fits with the bottom shell of the ship, and then the rust removal work is started, realizing the mechanized operation of ultra-high pressure water rust removal for the entire ship.

[0020] The rust removal vehicle uses batteries as energy, which is energy-saving and environmentally friendly. The battery and controller box adopt a waterproof design, which is suitable for the harsh environment of ultra-high pressure water operations at the bottom of the dock.

[0021] A support wheel 3 and a steering wheel 4 are installed below the vehicle body support 1 . The steering wheel 4 is connected to a control handle. The control handle includes a control rod and a steering wheel installed above the control rod. A seat 5 is installed on the vehicle body support 1 .

[0022] The lifting device includes a lifting bracket and a lifting electric cylinder for controlling the movement of the lifting bracket. The lifting bracket includes a telescopic rod 6 and a lifting panel 7 installed on the upper end surface of the telescopic rod 6. The lifting electric cylinder moves up and down to control the telescopic rod 6 to extend and retract, thereby driving the rust removal head 2 to move up and down.

[0023] The lifting panel 7 is a slide rail 8, and the lower end surface of the rust removal head 2 bracket is provided with a slider 9 that moves in coordination with the slide rail 8. The slide rail 8 and the slider 9 cooperate to drive the rust removal head 2 to move left and right.

[0024] The adjusting device comprises a motor 10 , a rotating shaft 15 and an adjusting assembly. The rotating shaft 15 controls the upward and downward movement of the adjusting assembly. The output end of the motor 10 is connected to the rotating shaft 15 .

[0025] The adjustment assembly includes a fixed seat 11, a gear 12 movably mounted on the fixed seat 11, and a movable shaft. The gear 12 is meshed and connected with the rotating shaft 15, and the movable shaft is movably connected with the gear 12 via a connecting piece.

[0026] The movable shaft comprises an upper half shaft 13 and a lower half shaft 14 , and the upper half shaft 13 and the lower half shaft 14 are hingedly arranged.

The four motors 10 respectively control the up and down movement of the adjusting assembly. The motor 10 drives the rotating shaft 15 to rotate. Since the gear 12 is meshed with the rotating shaft 15, the gear 12 is driven to rotate. At the same time, the movable shaft moves upward during the rotation of the gear 12, so that the rust removal head 2 fits the bottom shell of the ship, and the rust removal work begins. Since there are 4 adjusting devices that can adjust different heights, the rust removal head 2 presents different inclined surfaces, which better fits the bottom shell of the ship to achieve the purpose of rust removal.

[0029] High-pressure water is output by an ultra-high-pressure pump and output to the working surface through a hose and a nozzle for ultra-high-pressure water jet rust removal. A sealed cover is installed outside the nozzle, and the sealed cover is connected to a vacuum system. During jet rust removal, vacuum suction is performed synchronously to suck away the sewage in the cover. A mobile carrier is also provided to drive the nozzle to move on the working surface according to instructions to carry out large-area rust removal operations. During ultra-high-pressure water jet rust removal, the water pressure is 200~300MPa, the flow rate is greater than 30L / min, and the vacuum degree in the cover is lower than 0.06MPa.
