Dredging device for thermocouple mounting hole of gasification furnace

The utility model discloses a dredging device for a thermocouple mounting hole of a gasification furnace. The dredging device comprises a fixed plate, a first motor is fixedly connected to the upper surface of the fixing plate, a first bearing is fixedly connected to the surface of the output end of the first motor, and a sleeve is fixedly connected to the lower surface of the fixing plate. The utility model has the following advantages and effects: in the dredging process, as the positions of the mounting holes in different gasifiers are inconsistent, the second motor is started to drive the rotating shaft to rotate and then drive the gear to rotate, and the gear drives the strip-shaped plate to ascend or descend through the teeth, so that the gasification furnace is dredged; the height of the fixing plate can be adjusted, a threaded ring is screwed after adjustment so that the threaded ring can make contact with one side of the U-shaped plate, the fixing plate can be supported through cooperation with arran
