Hydraulic lifting construction device and method for inner steel barrel of chimney
The invention creatively specifically relates to hydraulic lifting construction device and method for an inner steel ball of a chimney. The construction device comprises a foundation and a vertical column; a hydraulic jack is mounted on the top end of the vertical column; a flexible guide rail is arranged between the top part of the vertical column and the top part of an outer barrel of the chimney; a rigid guide rail is vertically arranged on the vertical column; a steel strand which is anchored to a hydraulic jack downwards passes through the rigid guide rail to be anchored to a lug which is welded to the inner steel barrel; when in use, the hydraulic jack is operated to pull the steel strand to upwards move to lift the lug to lift the inner steel barrel; the upper part and the lower part of the inner steel barrel are respectively raised to reach the height of one inner steel barrel section along the flexible guide rail and the rigid guide rail, and one new inner steel barrel section is connected to the lower end of the inner steel barrel, the operation is repeated until the lug is raised to the maximum, then the lug is welded again, and the operation is repeated until mounting is done. The hydraulic lifting construction device and method for the inner steel barrel of the chimney are simple and convenient to construct, high in quality, high in efficiency, safe, reliable, high in construction safety and convenience, small in construction period, and low in cost.
