Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to a robot used for spraying the bottom of a ship. Background Art

[0002] A dock is a dock-type building used for shipbuilding. It can accommodate ships in and out after being filled with water, and can be used to build ships on a dry bottom after being drained. Ship maintenance such as rust removal and painting is generally carried out in a dock. After the ship enters the dock, the hull is supported by the dock piers, so that there is a certain space between the bottom of the ship and the dock bottom for easy operation. At present, the painting maintenance of the bottom of the ship is generally carried out by the staff using handheld spraying equipment. Manual operation is not only inefficient, but also because the height of the dock pier is less than 2 meters, it is inconvenient for workers to spray, and the spraying quality cannot be guaranteed.

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0022] In the embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the robot for spraying the bottom of a ship comprises a spray head 1 and a manipulator 2. The spray head 1 is mounted on the manipulator 2. The manipulator 2 can be used to adjust the spray angle of the spray head 1. The height of the manipulator 2 is adjustable.

[0023] The displacement mechanism 3 is used to drive the manipulator 2 to move horizontally forward, backward, left and right;

[0024] The vehicle body 4 is used to install the displacement mechanism 3 and drive the displacement mechanism 3 to move.

[0025] The vehicle body 4 can move on the bottom of the ship, the displacement mechanism 3 can adjust the front, rear, left and right positions of the nozzle 1, two or more nozzles 1 can be installed on the manipulator 2 for painting operations, the manipulator 2 can adjust the up and down position and angle of the nozzle 1, so that the nozzle 1 can paint various positions on the bottom of the ship. The robot can perform spraying operations in the narrow space on the bottom of the ship by adjusting the position of the nozzle 1, which not only has high work efficiency but also can ensure the spraying quality.

[0026] In the embodiment, Figure 3 As shown, the displacement mechanism 3 includes a first linear slide 31 and a second linear slide 32 arranged vertically. The first linear slide 31 and the second linear slide 32 ensure the front-back and left-right movement accuracy of the nozzle 3, and at the same time, the effect speed is fast and the efficiency is high.

[0027] In the embodiment, Figure 1 , Figure 4 As shown, the manipulator 2 includes a base 21 and a rotating arm 22 circumferentially matched with the base 21, and a rotating joint 23 is provided on the rotating arm 22, and the nozzle 1 is installed on the rotating joint 23. A plurality of rotating arms 22 can be provided as needed, and the height of the nozzle 1 can be adjusted by the rotating arm 22, and the rotating joint 23 can drive the nozzle 1 to rotate, so as to adjust the angle of the nozzle 1.

[0028] In the embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the spray head 1 is equipped with a trumpet-shaped retaining ring 5. The retaining ring 5 ensures that the paint mist will not splash during the painting process.
