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

[0022] according to Figure 1 —4: The utility model provides a grinding device for ship maintenance: comprising a U-shaped plate 1 with an opening downward, and two electromagnets 2 arranged at the bottom of the U-shaped plate 1; comprising a cylinder 4 controlled to move by a motor 3 at the upper end of the inner part of the U-shaped plate 1, the cylinder axis of the cylinder 4 facing downward and the end of which is provided with a rotating disk 6 fixed by a fixing pin 5, the lower end of the rotating disk 6 is provided with an inclined motor 7, the end of the output shaft of the motor 7 is provided with a grinding sheet 701, mounting platforms 101 are respectively provided on both sides of the outer side of the U-shaped plate 1, and a cylinder 8 is provided at the lower end of the mounting platform 101, the cylinder axis of the cylinder 8 facing downward and the end of which is provided with a connecting plate 9, and universal wheels 10 are respectively provided at both ends below the connecting plate 9; by providing the inclined motor 7 and providing the grinding sheet 701 at the end of the output shaft of the motor 7, the device can grind both sides of the weld, and by providing the cylinder 8, the connecting plate 9 and the universal wheel 10, the device is easy to move;

[0023] As an improvement, a guide groove 102 is provided at the inner upper end of the U-shaped plate 1, a rotating screw rod 103 is provided in the guide groove 102, a motor 3 is key-connected with the screw rod 103, a guide platform 401 with the same cross section as the guide groove 102 is provided at the upper end of the cylinder 4, and a threaded hole corresponding to the screw rod 103 is provided in the middle of the guide platform 401; in this way, the screw rod 103 can be driven to rotate by the motor 3, so that the guide platform 401 slides in the guide groove 102, thereby driving the cylinder 4 to move;

[0024] As an improvement, an anti-slip plate 501 is provided at the upper end of the fixing pin 5, and the length of the lower part is the same as the thickness of the rotating disk 6. The rotating disk 6 includes an upper rotating disk 601 fixedly arranged at the end of the cylinder shaft of the cylinder 1 4, and a lower rotating disk 602 rotatably arranged with the upper rotating disk 601. A plurality of positioning holes 603 with equal distances to the center of the circle are provided at equal angles on the upper rotating disk 601 and the lower rotating disk 602. The upper end of the motor 2 7 is connected to the rotating disk 6 through a triangular block 702; in this way, the motor 2 7 can be driven to rotate by rotating the lower rotating disk 602, and the angle between the lower rotating disk 602 and the upper rotating disk 601 can be fixed by inserting the lower part of the fixing pin 5 into the positioning holes 603 of the upper rotating disk 601 and the lower rotating disk 602. The triangular block 702 can make the motor 2 7 in an inclined state, so that welds in different directions can be polished;

[0025] As an improvement, the cross-section of the mounting platform 101 is larger than that of the cylinder 8. When the cylinder shaft of the cylinder 8 contracts, the lower end surface of the universal wheel 10 does not exceed the lower end surface of the electromagnet 2. When the cylinder shaft of the cylinder 8 extends, the lower end surface of the universal wheel 10 exceeds the lower end surface of the electromagnet 2, and the side of the connecting plate 9 does not contact the electromagnet 2 when it moves. In this way, the mounting platform 101 can stably fix the cylinder 8, and the connecting plate 9 will not cause damage to the electromagnet 2 when the cylinder shaft of the cylinder 8 moves.

[0026] The principle of the utility model is as follows: when in use, first start the cylinder 2 8 to extend the cylinder shaft of the cylinder 2 8 until the lower end surface of the universal wheel 10 exceeds the lower end surface of the electromagnet 2, then push the device to the top of the weld, then retract the cylinder shaft of the cylinder 2 8 to make the lower end surface of the electromagnet 2 contact the hull, then energize the electromagnet 2 to preserve the magnetism, then remove the fixing pin 5, rotate the lower rotating disk 602, so that the grinding sheet 701 can move along the weld, then reinsert the fixing pin 5 into the upper rotating disk 601 and the lower rotating disk 602. The positioning hole 603 of the plate 602 is then started, and the motor 27 and the cylinder 14 are started. The motor 27 drives the grinding sheet 701 to rotate, and the cylinder 14 causes the grinding sheet 701 to descend so that the grinding sheet 701 grinds the weld. When the grinding sheet 701 is in a suitable position, the cylinder 14 is closed, and then the motor 3 is started. The motor 1 drives the screw rod 103 to rotate, so that the guide platform 401 slides in the guide groove 102, and then drives the motor 27 to move, so that the grinding sheet 701 grinds the weld.
