The invention discloses a clutch device used for a boiler soot blower running vehicle and belongs to the technical field of boiler equipment. The clutch device comprises a walking main shaft, a shifting fork structure, a clutch cover, a clutch claw disc, a transmission gear, a gear bearing seat, a linkage disc and a universal shaft type shifting fork set, wherein the clutch cover, the clutch claw disc, the transmission gear, the gear bearing seat, the linkage disc and the universal shaft type shifting fork set are sequentially arranged on the walking main shaft from front to back in a sleeving manner. The gear bearing seat is fixedly connected with the walking main shaft. The clutch cover is fixedly connected with the gear bearing seat, and the clutch cover and the gear bearing seat are arranged on the front side and the rear side of the transmission gear correspondingly. The clutch claw disc is arranged in a cavity in a sliding manner in the front-back direction and can drive the gear bearing seat to rotate, wherein the cavity is composed of the clutch cover and the transmission gear. A return spring is arranged between the clutch claw disc and the clutch cover. The face, opposite to the transmission gear, of the clutch claw disc is provided with a convex claw and a concave claw which are matched. The linkage disc is fixedly connected with the clutch claw disc, and the convex claw and the concave claw can be separated from each other and combined with each other through the front-back movement of the linkage disc. The universal shaft type shifting fork set abuts against the rear side of the linkage disc through a universal ball on the universal shaft type shifting fork set.
