Lifting type boiler bottom supporting platform for pulverized coal boiler of thermal power plant

A lifting type boiler bottom supporting platform of a pulverized coal boiler of a thermal power plant is characterized in that a supporting beam body comprises a main beam and an auxiliary beam, and the main beam comprises a middle beam and a wing beam; the middle beam is connected between the two auxiliary beams, and the wing beams are symmetrically connected to the outer sides of the two auxiliary beams. Beam end plates are installed at the ends of the wing beams and have the same angle as the slope face of the furnace bottom slope water cooling wall in contact with the beam end plates. The lifting driving mechanism is connected to the supporting beam body and drives the supporting beam body to achieve lifting of the whole furnace bottom supporting platform. The walking board pedal is laid on the upper end face of the supporting beam body to form an operation walking board face. The lifting guide device is installed at the lower end of the spar and close to the spar end plate. The device can be placed and i
