Example Embodiment

[0026] Combine below Figure 1-Figure 3 Introduce the tool of the present invention.

[0027] Such as figure 1 As shown, the tool of the present invention includes a hoisting frame 10 and four electric hoists (three electric hoists are shown in the figure). The hoisting frame 10 is fixed on the top of the chimney 34; the lower surface of the hoisting frame 10 is provided with lifting lugs 14, and the electric hoist is installed on the lifting lugs 14; and the four electric hoists are evenly distributed on the circumference of the same diameter as the outer diameter of the steel inner cylinder Above, when the tool of the present invention is introduced below, two electric hoists located on a diameter of the above-mentioned circumference are used as a group, and the four electric hoists are divided into two groups, A group and B group, A group has two electric hoists 11a and 11a'; Group B has two electric hoists 11b and 11b'. The power cables and control cables 13 of the electric...

Abstract

The invention belongs to the technical field of hoisting construction and provides a tool for hoisting a steel inner barrel of a chimney, aiming at solving the problems of an existing method for hoisting the steel inner barrel of the chimney that the safety risk is great and the cost is high. The tool comprises a hoisting frame, four power devices and a hoisting device, wherein the hoisting frame is fixed at the top of the chimney; the power devices are fixed on the lower surface of the hoisting frame; the hoisting device can move in the chimney up and down. With the adoption of the tool provided by the invention, the safety of the work of hoisting the steel inner barrel of the chimney is improved and the working cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of hoisting construction, and in particular relates to a tool for hoisting a steel inner tube of a chimney and a use method thereof. Background technique [0002] The exhaust towers of nuclear power plants usually use sleeve-type or multi-pipe chimneys to discharge the flue gas separately due to the radioactivity and corrosiveness of the flue gas. A steel inner cylinder needs to be installed in a telescopic or multi-pipe chimney. At present, the following methods are usually used to hoist the steel inner cylinder: [0003] (1) Hydraulic lifting method, the tools used usually include hydraulic hoist, hydraulic pump station, hydraulic automatic control valve, high-pressure oil pipe, oil storage tank, etc. The disadvantages of this method are: the rental and purchase costs of the tools used are relatively high, and the preparation time It is relatively long and requires the guidance of professionals; if it is ...
