Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe surface processing, in particular to a surface repair structure for galvanized steel pipe processing. Background Art

[0002] Hot-dip galvanizing is a process in which molten metal reacts with an iron matrix to produce an alloy layer, thereby combining the matrix and the coating. Hot-dip galvanizing is to first pickle the steel pipe to remove iron oxide on the surface of the steel pipe. After pickling, the steel pipe is cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed ammonium chloride and zinc chloride aqueous solution tank, and then sent to a hot-dip plating tank. After the galvanized steel pipe has been used for a period of time, the original paint on the outer surface of the galvanized steel pipe falls off due to corrosion. After the original paint falls off, it needs to be repaired, so a tin-plated pipe surface repair device is needed.

[0003] In the existing galvanized pipe surface repair process, the pipe needs to be fixed, which is generally repaired by clamping both ends. However, the ends of the pipe cannot be painted because they are clamped by the clamping device.

[0004] As disclosed in Chinese patent CN218340134U, a surface repair structure for galvanized steel pipe processing is proposed. The structure is constructed by inserting one end of the tin-plated pipe into the fixed cylinder through the through hole, and by twisting the threaded rod, the threaded rod drives the fixed plate to fix the pipe. Then, the cylinder is turned on, and the cylinder drives the limit column to move to the side close to the fixed cylinder to further clamp the pipe. The suction pump is turned on, and the suction pump draws the paint in the storage chamber to the spray gun, and the spray gun sprays the paint onto the pipe. At the same time, the motor is turned on, and the motor drives the screw rod to rotate, so that the threaded connecting plate moves on the sliding rod, thereby adjusting the position of the spray gun, and then the spray gun sprays the paint to the required repair position of the pipe. When the spray gun sprays the paint, the anti-expansion box limits the diffusion area of ​​the mist paint, thereby reducing the leakage of the paint, and the excess paint falls into the storage chamber from the leakage hole at the bottom of the anti-expansion box for recycling.

[0005] However, when the surface of the steel pipe is galvanized in the prior art, since the galvanizing process generates gases that are harmful to the human body, it is necessary to prevent the gases from causing physical harm to the workers during the galvanizing process.
