The embodiment of the invention discloses a hydraulic lifting device based on an inverted mounting method for a chimney titanium steel inner pipe. The hydraulic lifting device based on the inverted mounting method for the chimney titanium steel inner pipe comprises a feeding base arranged on the bottom part of an assembling barrel, wherein a clamping and lifting device and a clamping and rotatingdevice are arranged on the periphery of the assembling barrel from top to bottom; the clamping and lifting device comprises a short-range lifting frame; an arc-shaped clamping sliding block is arranged on the short-range lifting frame; an elastic guide pillar is arranged at the lower end of the arc-shaped clamping sliding block; the clamping and rotating device comprises a rotating support and anarc-shaped rotating and clamping block used for clamping a lower-layer assembling barrel and capable of radially rotating along the rotating support; and a guide slot corresponding to the elastic guide pillar is formed in the upper end of the arc-shaped rotating and clamping block. A method comprises the steps of assembling the device, lifting an upper-layer assembling barrel, positioning the lower-layer assembling barrel, and lifting the lower-layer assembling barrel. According to the hydraulic lifting device and the hydraulic lifting method based on the inverted mounting method for the chimney titanium steel inner pipe provided by the invention, by utilizing the manner of the clamping and rotating device, up-and-down center alignment and angle alignment between the two upper and lower adjacent assembling barrels are realized, and the assembling efficiency and the assembling precision degree of the chimney titanium steel inner pipe are improved.
Description
technical field [0001] The embodiment of the present invention relates to the technical field of chimney inner pipe inversion, in particular to a chimney titanium steel inner pipe hydraulic lifting device and method based on the inversion method. Background technique [0002] At present, the domestic steel inner cylinder construction technology basically adopts the inversion method. The inversion method mainly includes three types: air pressure lifting, hydraulic lifting and hydraulic lifting. These methods have been relatively mature in the construction of self-supporting chimney steel inner cylinders. [0003] In the process of installing the steel inner cylinder of the chimney by hydraulic jacking and flipping, the following steps are usually included: [0004] Prefabricate the steel inner cylinder of the chimney into several standard sections at the production site; install the lifter on the top of the outer cylinder of the chimney, and thread the steel strands; transpor...
