The ceramic fiber lining on the furnace top will be powdered due to the high temperature, causing the lining surface to fall off, resulting in high wall temperature and increased energy consumption. Therefore, when the lining surface falls off, the lining needs to be repaired. During the repair, the original lining is removed to a certain thickness and the surface of the original lining is cleaned after removal, and then the spray paint for repair is sprayed on the cleaned original lining surface.

[0004] However, the above scheme still has defects. Although the fixed clamp, hand grip, sphere, fixed block, electric telescopic rod and tripod are used to achieve stable spraying of the spray gun, the spraying range of the spray gun is limited. When it is necessary to spray other longitudinal directions, the tripod needs to be lifted to change the position of the spray gun, and sometimes the box needs to be moved. When it is necessary to spray other surrounding directions, the box needs to be rotated and the tripod needs to be moved. Not to mention the low degree of automation, it is also too time-consuming, which reduces the efficiency of repairing the heating furnace lining and brings a bad user experience.
