Boiler furnace overhauling device

Abstract

The utility model relates to a boiler furnace overhauling device in the technical field of boiler furnace overhauling. A motor II is started to synchronously drive a reciprocating lead screw I to rotate, so that a lead screw nut drives a bottom plate to move up and down so as to control a touch plate to move up and down, and the touch plate synchronously drives an anti-skid pad to abut against the bottom of a boiler hearth, so that a bottom box cannot move, and maintenance is facilitated. After a second motor is started, a second reciprocating lead screw drives two first lead screw nuts to move reversely, a second connecting base drives one end of a rotating rod to move towards the two sides of the working platform, due to the fact that the other end of the rotating rod is limited by the connecting base, the rotating rod rotates, then the working platform is driven to ascend, and when the two first lead screw nuts get close to each other, the working platform descends; and therefore, different height positions of the boiler furnace can be conveniently overhauled.
