Description

TECHNICAL FIELD

[0001] The utility model relates to a shot blasting derusting device, in particular to a shot blasting derusting device for robot derusting operation. BACKGROUND

[0002] After the ship sails in water for a period of time, the paint attached to the surface thereof is stripped, and the surface of the ship shell is corroded and rusted after long time contact with water. If derusting is not performed in time, the rust will spread to the whole surface of the ship shell, reducing the structural strength of the ship and endangering the safety of sailing. Currently, manual grinding derusting is usually adopted. However, when the manual derusting operation is performed by holding the derusting equipment, most of the labor is mechanical repetitive operation, which will result in high labor intensity and low work efficiency. Moreover, the side surface of the ship shell is a vertical surface. When derusting is performed, the worker must also perform climbing operation, and the work danger is greatly increased. When the bottom surface of the ship shell is derusted, the worker needs to hold the derusting equipment to the head for derusting operation. Such working posture cannot be maintained for too long time, and the worker needs to rest after a period of time, resulting in low work efficiency.

[0003] Due to the above limitations of manual operation, currently, how to use a robot to replace manual derusting operation on the surface of the ship shell is studied. The robot is suitable for mechanical repetitive operation and various working conditions, and can replace manual climbing operation, reducing the work danger of the worker. In the derusting operation by using the robot, one of the main methods is to set a shot blasting derusting device on a robot chassis capable of climbing on the surface of the ship shell, so that the robot chassis and the shot blasting derusting device are combined to perform derusting operation on the surface of the ship shell. Therefore, a shot blasting derusting device suitable for robot derusting operation needs to be developed, so that the robot can automatically derust the side surface and the bottom surface of the ship shell.

CONCRETE EMBODIMENT

[0028] The utility model will be further explained in connection with the drawings and specific embodiments.

[0029] Reference Figures 1-3 The utility model relates to a shot blasting derusting device for robot derusting operation, including shot blasting machine shell 2, the lateral wall of shot blasting machine shell 2 is installed with shot blasting motor 1, and the output end of shot blasting motor 1 is inserted into shot blasting machine shell 2 and is fixedly connected with the shot blasting wheel arranged in shot blasting machine shell 2.
