Barrel connecting method without support

Abstract

The invention relates to a rotary kiln barrel, in particular to an installation method of the rotary kiln barrel. A barrel connecting method without support comprises the following steps that barrels are divided into sections, and connecting points are positioned, namely, barrel rounds are divided into sections according to the number of installing draw-in blots and lap jointed plates, and welding positions of the draw-in bolts and the lap jointed plates are positioned; a draw-in bolt base is welded, the draw-in bole base is welded to one of two sections of barrels which need to be connected according to preset positions; after the barrels are hoisted and the two sections of the barrels are hoisted and abutted, the draw-in bolts are used for positioning the welding position of the other bolt base, and welding is conducted, then the draw-in bolts are fixed through the two bolt bases, the lap jointed plates are welded to the preset positions, and a single barrel is fully welded; installation is finished, the draw-in blots bear tension, the lap jointed plates bear shear force, and all the barrels of the rotary kiln are connected together. The barrel connecting method without the support does need to manufacture a steel support, and is economical, practical, convenient to achieve and efficient.

Description

technical field [0001] The invention relates to a rotary kiln shell, in particular to a method for installing the rotary kiln shell. Background technique [0002] The rotary kiln shell is generally divided into multiple sections and transported to the construction site for assembly and installation on site. In the past, there were two methods for the on-site assembly of the rotary kiln shell; the first method is to assemble several large sections on the ground and then set several steel supports on the pier (the steel supports support the shell when it is docked), Then carry out docking; the second method is to install steel brackets at the joints of every two sections of the cylinder, and then carry out aerial assembly; the first method requires large truck cranes or crawler cranes, and the installation cost is high; the second method requires doing Multiple steel brackets increase the construction period and installation cost; therefore, the original installation method c...
