Thermal power generating unit draught fan structure support overall transfer device and transfer method

Abstract

The invention discloses a thermal power generating unit draught fan structure support overall transfer device and a transfer method. The overall transfer device is mainly composed of a lifting system, a rail system, a traction system and structure strengthening facilities. The transfer method specifically includes the following steps that: a steel structure support and equipment overall transfer scheme is designed; the scheme is checked, calculated, adjusted and optimized; the arrangement location of a hydraulic jack and the arrangement location of a transfer rail are determined; the ground at the rail is leveled, and a foundation is formed through pouring and is leveled; a steel plate is laid on the foundation; rail beams are arranged and welded, and a steel structure is strengthened; steel structure supporting equipment is strengthened; cable ropes are arranged; a vertical column and a column bottom plate are separated from each other; the hydraulic jack is arranged; overall jacking is performed; a heavy object conveying device is arranged; the jack is disassembled; overall horizontal movement is performed; integral jacking is performed; after the heavy object conveying device is dissembled, and the steel structure support is arranged in place; the vertical column is connected with the bottom plate; and temporary facilities are removed. According to the thermal power generating unit draught fan structure support overall transfer device and the transfer method of the invention, overall transfer construction technologies are adopted, and therefore, the quality of a project can be ensured, and safety risks can be reduced, and the construction period of the project can be shortened greatly.

Description

technical field [0001] The invention relates to the construction of a thermal power unit, in particular to an overall displacement device and a displacement method for a structural support of an induced draft fan of a thermal power unit. Background technique [0002] In recent years, in the process of environmental protection transformation of thermal power units, installation projects that need to adjust the layout of plant equipment are often encountered, and the method of first dismantling and then installing is often used for adjustment. This method is time-consuming and labor-intensive. Cause damage, and have adverse effects on project quality, construction period, and benefit. Contents of the invention [0003] In order to overcome the defects and deficiencies of the above-mentioned prior art, the present invention provides an overall shifting device and a shifting method for the structural support of the induced draft fan of a thermal power unit. [0004] Technical...
