Problems solved by technology

[0003] In the case where the "steel cable hydraulic jack" cannot be arranged on the top of the chimney, the built-in hydraulic lifting and flip-chip construction device is currently used to lift the steel inner cylinder from the zero-meter ground of the chimney. Except for the welding between the 1.2mm thick titanium plates, the inner cylinder is not allowed to be connected with other structural structures. If this method is used, the inner titanium plate must be opened and then welded to the outer steel plate, which will damage the titanium plate. The anti-corrosion structure of the cylinder, so this method cannot be used for the construction of the titanium plate steel inner cylinder

Embodiment 1

[0027] Such as Figure 1-Figure 6 As shown, the thermal power plant chimney titanium plate steel inner cylinder external hydraulic lifting and flip-chip construction device has a lifting system foundation 3 arranged on the outside of the steel inner cylinder foundation 2 along the circumferential direction. The lifting system foundation 3 is a reinforced concrete structure, and the lifting system Foundation 3 needs to ensure that the foundation bearing capacity meets the requirements. If it is backfill, the backfill must be backfilled in layers and compacted. The hoisting system foundation 3 is provided with a ring-shaped steel structure support system along the circumferential direction. The ring-shaped steel structure support system includes the feed inlet side support steel column 4 and the main support steel column 5 installed on the lifting system foundation 3 through the anchor bolts 6, the feed inlet side support steel column 4, the main support steel column 5 All are ...

Embodiment 2

[0030] Such as Figure 7-Figure 8 as shown in Figure 1-Figure 5 As shown, the thermal power plant chimney titanium plate steel inner cylinder external hydraulic lifting and flip-chip construction device includes a lifting system foundation 3 arranged on the outside of the steel inner cylinder foundation 2 along the circumferential direction. The lifting system foundation 3 is a reinforced concrete structure, and the lifting system Foundation 3 needs to ensure that the foundation bearing capacity meets the requirements. If it is backfill, the backfill must be backfilled in layers and compacted. The foundation 3 of the lifting system is provided with the feed inlet side support steel column 4 and the main support steel column 5 along the circumferential direction through the anchor bolts 6, and the feed inlet side support steel column 4 and the main support steel column 5 are combined welded H-shaped steel , the strength of the supporting steel column 4 on the side of the feed...

Abstract

The invention relates to a titanium plate steel inner tank reversed construction device for a chimney of a thermal power station. The titanium plate steel inner tank reversed construction device is provided with a hoisting system foundation distributed on the outer side of a steel inner tube foundation in the circumferential direction, wherein an annular steel structure supporting system with a material inlet on the surface is fixed on the hoisting system foundation, the annular steel structure supporting system is arranged on the outer side of a steel inner tank, an outrigger is arranged at the top of the annular steel structure supporting system radially, a hydraulic hoisting system is installed on the outrigger, a box-type horizontal annular beam is arranged at the bottom of the hydraulic hoisting system, a clamping block welded with the steel inner tube is clamped on the box-type horizontal annular beam, and a draw bar is arranged between an outer tube wall of the chimney and the annular steel structure supporting system. The titanium plate steel inner tank reversed construction device has the advantages of being convenient to construct, clear in stress, easy and convenient to operate, high in safety coefficient and good in engineering quality and is particularly suitable for traditional chimney transformation engineering where bearing systems cannot be distributed at the top.

Description

technical field [0001] The invention relates to a chimney steel inner cylinder construction device, in particular to a thermal power plant chimney titanium plate steel inner cylinder external hydraulic lifting and flipping construction device. Background technique [0002] With the advancement of science and technology and the improvement of national environmental protection requirements for thermal power plants, the design of chimney inner cylinders has gradually developed from brick inner cylinders and sulfuric acid drop point corrosion-resistant steel inner cylinders to titanium plate steel inner cylinders. Practice has proved that titanium plate steel inner cylinders The cylinder has good corrosion resistance and has a very wide application prospect. In the installation of the steel inner cylinder, the "cable hydraulic lifting and inversion method" is generally used. This method requires a steel cable hydraulic jack load-bearing system on the top of the chimney outer...
