Problems solved by technology

[0002] In the past construction of thermal power projects, since the installation height of the steel roof truss of the main factory building is generally more than 20 meters, it is necessary to use large-scale lifting equipment when hoisting the steel roof truss, and the large-scale lifting equipment is relatively heavy, so the existing hoisting This method not only increases the difficulty of large-scale equipment transfer, but also has troublesome operation and poor safety, which brings great inconvenience to the hoisting work and prolongs the hoisting time

Abstract

The invention relates to a hoisting construction method for a steel roof truss of a main power house of a power plant and a special hoisting device. The special hoisting device and the steel roof truss are hoisted to a bridge crane of the main power house by large hoisting equipment for boilers, the steel roof truss is hung to a chain block of the mounted special hoisting device, the bridge crane of the main power house is moved to an in-place point required by the steel roof truss, and the steel roof truss is subjected to microadjustment in-place mounting through the chain block. The hoisting construction method for the steel roof truss of the main power house of the power plant and the special hoisting device have the advantages of simple operation and scientific design; and in the hoisting method, the steel roof truss of the main power house is hoisted through the stability and back-and-forth flexibility of the bridge crane of the main power house, great convenience is brought to the hoisting work, the re-input and cycle of construction mechanical equipment of a thermal power construction field are reduced, the safety of the process of hoisting the steel roof truss in place is ensured, the construction speed is improved, and the construction cost is saved.

Description

technical field [0001] The invention relates to the field of steel roof truss hoisting in thermal power engineering construction, in particular to a construction method for hoisting steel roof trusses of a power plant main building and a special lifting device for hoisting. Background technique [0002] In the past construction of thermal power projects, since the installation height of the steel roof truss of the main factory building is generally more than 20 meters, it is necessary to use large-scale lifting equipment when hoisting the steel roof truss, and the large-scale lifting equipment is relatively heavy, so the existing hoisting The method not only increases the difficulty of large-scale equipment transfer, but also has troublesome operation and poor safety, which brings great inconvenience to the hoisting work and prolongs the time of hoisting. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior ar...
