The utility model discloses a kind of ash
silo board joint dredging devices, belong to ash
silo maintenance equipment field.Its technical scheme is, a kind of ash
silo board joint dredging device, including drilling component, the drilling component includes fixed base, the fixed base is equipped with sliding base, drilling motor is installed on the sliding base, and
drill bit is installed on the output shaft of drilling motor;Still including lifting component, the lifting component includes
winch, the
winch is connected with
wire rope,
wire rope is connected with the sliding base, and
wire rope can drive the sliding base upward motion along the fixed base.This device adopts straight line lifting structure, and sliding base carries drilling motor and
drill bit whole up, is driven by
winch, with greater
stroke, can dredge deeper ash silo board joint;When sliding base drops to low position simultaneously, device overall height is lower, facilitate arrangement below ash silo
discharge port, position interference is small, facilitate use operation.
