Processing system for renovating inner wall of vertical steel drum

The invention discloses a processing system for renovating the inner wall of a vertical steel drum which has the advantages of simple and reasonable structure, high stability and low cost. The end of a spray rod is connected with a torch firing device and a brushing head; the spray rod is connected with a spray rod rotating motor and an elevation driving mechanism through a transmission mechanism; a main frame is provided with a clamping apparatus in the corresponding position of the spray rod; the clamping apparatus is connected with a drum rotating motor through the transmission mechanism; the main frame is provided with a drum bracket; a drum support plate elevation driving mechanism is arranged on the drum bracket; and a drum support plate is connected with the drum support plate elevation driving mechanism. The processing system for renovating the inner wall of the vertical steel drum of the invention improves the elevation and displacement structure and reasonably combines the components, thereby simplifying the equipment structure, enhancing the stability, reducing the cost and lowering the difficulty in equipment manufacture. In addition, the torch firing and the brushing are carried out on the same station, thereby further simplifying the equipment structure.
