Ship rust removal device

Abstract

The invention discloses a ship rust removal device, and relates to the technical field of ship rust removal, the ship rust removal device comprises a movable base, a fixed support and a side support, the fixed support is of an inverted L-shaped structure, the fixed support is fixed on the top surface of the movable base, and a lifting table and a lead screw lifting mechanism for driving the lifting table to work are arranged in the fixed support; two guide rods capable of moving front and back are arranged on the front side of the lifting table in a bilateral symmetry mode, the front ends of the two guide rods are rotationally connected with the side support, two electric push rods are further installed between the lifting table and the side support, two rotating tooth rollers are installed at the two ends in the side support, and an adjusting tooth roller is arranged in the middle in the side support. A second motor connected with one rotating tooth roller is installed at one end of the top face of the side support, and a transmission crawler belt is connected between the two rotating tooth rollers in an engaged mode. According to the ship surface rust removal device, the horizontal inclination of the grinding piece can be adjusted, so that the grinding piece is suitable for the inclined ship surface and the surface with hole channels and gaps, rust removal on the ship surface is more convenient, and the rust removal effect is better.

Description

technical field [0001] The invention relates to the technical field of ship rust removal, in particular to a ship rust removal device. Background technique [0002] After a ship sails in the ocean for a period of time, the surface of the hull shell is easily corroded due to electrochemical corrosion and marine biological corrosion. Even if isolation and electrochemical corrosion protection are used, this event cannot be completely prevented. Therefore, it is necessary to regularly inspect the surface of the ship. Carry out rust cleaning. At present, the main methods of rust removal on the hull surface can be divided into the following three categories: 1. Artificial ship rust removal; 2. Chemical ship rust removal; 3. Mechanical ship rust removal. Among them, artificial ship rust removal is the ship rust removal method with the longest application time and the widest application range. Derusting of artificial ships takes manpower as the main labor force, and derusting work...

Problems solved by technology

However, this method also has certain limitations; on the one hand, because the Young's modulus of water is very small, no matter how high the water pressure is, it is difficult to achieve a high enough smoothness on the steel surface after treatment, so that the chelation degree of the secondary spraying is not enough Well, the paint is prone to peeling, bubbling and falling off; on the other hand, the steel after high-pressure water treatment is extremely prone to flash rust, and the treatment of flash rust often relies on complicated and expensive water-based anti-flash rust agents

The use of water-based anti-flash rust agents will increase the cost of rust removal. In addition, water-based anti-flash rust agents will greatly reduce the adhesion between the subsequent oil-based paint and the surface of the ship
