Embodiment Construction

[0024] A preferred embodiment will be given below, and the present invention will be described more clearly and completely in conjunction with the accompanying drawings.

[0025] Such as figure 1 , figure 2 , image 3 , Figure 4 with Figure 5 As shown, a marine adaptive grinding and polishing device includes a connecting rod 10 and a grinding and polishing belt 11 , and a handle 12 is provided at the upper end of the connecting rod 10 . The connecting rod is a telescopic rod.

[0026] Two rotating arms 20 are pivotally connected to the lower end of the connecting rod 10 , and the two rotating arms 20 are respectively located on the left and right sides of the connecting rod 10 . A vertical swing arm 30 is pivotally connected to the left end of the rotating arm on the left side of the connecting rod and the right end of the rotating arm on the right side of the connecting rod.

[0027] Two and two vertical swing arms 30 are all provided with driving wheels 40 for drivi...

Abstract

The invention discloses an adaptive grinding and polishing device for ship. The device comprises a connecting rod and a polishing belt. The lower end of the connecting rod is connected with two rotating arms by shafts. The two rotating arms are respectively arranged on the left and right sides of the connecting rod. The left end of a rotating arm on the left side of the connecting rod and the right end of a rotating arm on the right side of the connecting rod are connected with vertical swinging arms by shafts. The two rotating arms and the two vertical swinging arms are provided with drivingwheels used for grinding and polishing belts. The belts after grinding and polishing is in closed loop shapes. Belt tensioning components are connected to both of the two rotating arms by shafts. Thebelt tensioning component comprise telescopic sleeves and rolling wheels connected with the telescopic sleeves by shafts. The rolling wheels abut on the inner surfaces of the belts after grinding andpolishing. The device can polish and grind shafts in the narrow space of a ship. Adaptive wrapping can be realized for the polished shaft during polishing and grinding. The device realizes self-adaptive grinding of shafts with different diameters and shaft surfaces with different curvatures.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship-used self-adaptive grinding and polishing device. Background technique [0002] Due to the strong sunshine, high temperature, high humidity and high salt at sea, the pins in the ship's installation are easily rusted and corroded. In the narrow and long area of ​​the ship, the transmission shafting or pin shaft is arranged in the ship device, and the part exposed to the air, even if lubrication and anti-corrosion measures are added, after a period of time, there is still rust on the surface of the shafting system such as the pin shaft. [0003] In order to ensure that the pin shaft and other shaft systems can work normally in the future, in the case where chemical reagents cannot be used to remove rust, the rust can only be removed by grinding. [0004] In the long and narrow space of the ship where there is no maintenance space, not only the crew cannot enter, but even thei...
