Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0026] like Figure 1 to Figure 6 As shown, the extra-large rotary kiln barrel docking method of the present invention comprises the following steps:

[0027] a. Set up a temporary support 13 that can be adjusted to lift. The temporary support 13 is erected along the installation and arrangement direction of the cylinder body 7 and is compatible with the weight, shape and installation height of the cylinder body 7; The erection density increases accordingly. The lighter the cylinder body 7 is, the thinner the erection density of the temporary support 13 is, and the cost is saved as much as possible under the condition of satisfying safe construction; similarly, the shape of the temporary support 13 is erected according to the shape of the cylinder body 7. The height of the s...

Abstract

The invention discloses a butt joint method for giant rotary kiln barrels, wherein the method is mainly applied to installation and butt jointing of the giant rotary kiln barrels in the cement production industry. The method comprises the following steps that temporary supports which are adaptive to the barrels in weight, shape and installation height are set up according to the arrangement direction of the barrels; first two barrels are hoisted to the temporary supports, and radial adjusting devices and axial adjusting devices are installed along the butt joint seams of the two barrels; the butt joint straightness and concentricity of the barrels are measured through a total station instrument and adjusted through the radial adjusting devices, then the width of the butt joint seams is adjusted through the axial adjusting devices, and temporary fixing devices are welded to connect the two barrels; follow-up barrels are hoisted in sequence, are adjusted and are in butt joint according to the method, and finally the butt joint seams are welded. Due to the cooperation of the total station instrument, the radial adjusting devices and the axial adjusting devices, the butt joint method for the giant rotary kiln barrels has the advantages that the method is simple, installation is convenient and the construction period is short.

Description

technical field [0001] The invention relates to a rotary kiln installation method, which is mainly applied to the installation and docking of super large rotary kiln shells in the cement production industry, and can be extended to the docking work of all types of rotary kiln shells, and even the docking installation of all cylindrical equipment. Background technique [0002] The invention of the rotary kiln led to the rapid development of the cement industry, and at the same time promoted people's research on the application of the rotary kiln. Soon the rotary kiln was widely used in many industrial fields, and became more and more important in these productions, becoming the core of the production of corresponding enterprises. equipment. Its technical performance and operation determine the quality, output and cost of the company's products to a large extent. [0003] For conventional rotary kiln installation, it is necessary to align all the temporary and formal support p...
