The invention relates to a quick steel pipe lining plate rounding device which comprises two driven rollers and a driving roller arranged in a shape of Chinese character "Pin". The driving rollers aremounted at the front end of cross shaft and a turnplate is mounted at the back end of the cross shaft; the cross shaft is connected to a compression device and the compression device comprises a handle, an adjusting lead screw, a nut, a supporting rack, a connecting plate and a slide block, and the nut is mounted on the adjusting lead screw in a sleeving manner; the nut is fixedly connected to the top of the supporting rack, and the supporting rack is fixedly connected to a bottom plate; the upper end of the adjusting lead screw is fixedly connected to the handle and the connecting plate is arranged at the lower end of the adjusting lead screw; and the slide block is fixedly connected below the connecting plate, and the slide block is mounted on the cross shaft in a sleeving manner. The invention further provides an application method of the quick steel pipe lining plate rounding device. The application method comprises the following steps of adjusting the separation distance betweenthe driving rollers and the driven roller through the compression device to laminate a lining plate strip; enabling the driving rollers to rotate by rotating the turnplate, wherein the lining plate strip is driven to move forward by means of friction forces between the driving rollers and the lining plate strip, and meanwhile, the driven roller rotates in a follow-up manner; and further bending the lining plate strip by adjusting the compression device, wherein a round lining plate which meets a construction demand is obtained.
Description
technical field [0001] The invention relates to the field of manufacture and installation of steel pipe structures, in particular to a rapid rounding device for steel pipe liners and a method for using the same. Background technique [0002] With the development of society, more and more buildings need to adopt large spaces and large overhangs in order to meet the needs of appearance and function. These structures generally use steel pipes as the main material in the selection of materials, and steel pipes need to be used in the production and installation process. For butt welding, the welding quality generally requires first-level penetration welding, and the welding quality of the butt joint will directly affect the safety of the structure. In order to ensure the welding quality of steel pipe butt joints, steel liners need to be installed at the joints of steel pipes, and the quality of the steel liner settings will affect the quality of the weld seam. The conventional me...
