Upper frame supporting tool for ship bottom paint surface machining

The upper frame supporting tool for ship bottom paint surface machining comprises a tool frame, buckles are fixedly installed at the inner corners of the bottom of the tool frame, rolling wheels are fixedly installed in the inner walls of the buckles, a stand column is fixedly connected to the upper surface of the tool frame, a transverse column is fixedly connected to the top of the stand column, and the transverse column is fixedly connected to the top of the tool frame. A sliding rod is connected to the inner corner of the top of the front face of the limiting block in a penetrating mode. By adjusting the positions of the limiting blocks and the sliding rods in the clamping grooves and the sliding grooves, the two supporting blocks slide in the movable grooves, so that the contact area of the two supporting blocks and the bottom face of the ship can be flexibly adjusted, the supporting tool can be applied to painting operation of the bottom faces of different ships, and meanwhile, the working efficiency is
