[0050] The present application will be further described below in conjunction with the accompanying drawings and embodiments.

[0051] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application pertains.

[0052] It should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise, and it should be further understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the features, steps, operations, devices, components and / or combinations thereof.

[0053] The chimney inner cylinder installation platform provided by the embodiment is a multi-layer structure, modular chimney assembly platform, which can realize continuous operation of chimney assembly.

[0054] In the specific implementation process, the chimney inner cylinder installation platform comprises an external platform and an internal platform. The external platform and the internal platform are used to perform corresponding operations on the outside and the inside of the chimney inner cylinder, respectively;

[0055] The outer platform and the inner platform are both multi-layer structures; the outer platform and the inner platform are respectively provided with a communication channel to communicate the upper and lower layers of the corresponding platform; the multi-layer structure of the outer platform and the inner platform is used for modular combination according to the number of chimney inner tubes to realize the flow production process of different numbers of chimney inner tubes.

[0056] In the specific implementation process, according to Figures 1(a)-3(d) , the outer platform is a three-layer structure, and the inner platform is a two-layer structure. A channel is arranged below the first layer platform to communicate the inside and outside of the inner tube 1 and to level the horizontal installation reference of the inner tube 1. According to Figures 1(a)-3(d) , the middle 2 is a platform steel plate. The outer platform and the inner platform are respectively provided with a ladder to communicate the upper and lower layers. The platform can be modularly combined according to the number of chimney inner tubes, so as to have different flow production processes.

[0057] In the specific implementation process, the second layer platform of the outer platform is used for the girth seam welding, T-shaped weld seam welding of the lower section inner tube and the upper section inner tube outside, and the non-destructive testing and defect elimination of all weld seams of the two section inner tubes.

[0058] Among them, the outer platform is divided into three layers, which are the first layer platform 4, the second layer platform 5 and the third layer platform 6, respectively, for performing the external operation of the chimney inner tube, which are combination, welding detection and heat preservation process.

[0059] Specifically, the functions of each platform of the outer platform are as follows:

[0060] The first layer platform 4 of the outer platform is provided with a channel below to communicate the inside and outside and to level the horizontal installation reference of the inner tube. The main work is the combination and longitudinal seam welding of the upper and lower sections of the inner tube.

[0061] The second layer platform 5 of the outer platform mainly performs the girth seam welding and T-shaped weld seam welding of the lower section inner tube and the upper section inner tube, and the non-destructive testing and defect elimination of all weld seams of the two section inner tubes. The elevation of the second layer platform is slightly higher than the height of the girth weld when the inner tube is aligned;

[0062] The third layer platform 6 of the outer platform mainly performs the heat preservation of the inner tube. The elevation of the third layer platform ensures that the welding detection work of the second layer platform can be conveniently performed.

[0063] Guide rails 3 and sliding lifting facilities can be arranged between the chimney entrance and the outer platform, and guide rails and sliding lifting facilities can be arranged around the girth platform between the outer platform and the chimney, which can quickly lift the inner tube steel plate to the combination position,

[0064] The inner platform is divided into two layers, and the second layer is the main working surface, which has the same height as the second layer of the outer platform. When the welding detection work is carried out on the second layer of the outer platform, the second layer of the inner platform simultaneously carries out the inner welding detection work. The inner platform is connected with the inner cylinder of the chimney by rubber wheels to avoid damaging the metal or coating of the inner wall of the chimney. The inner platform can be set according to actual needs, and if the inner cylinder is a non-composite steel plate, the inner platform can not be set.

[0065] The second layer of the outer platform and the inner platform is paved with patterned steel plates as the main working surface of the platform. The gap between the outer platform and the chimney is paved with flexible sealing pads with fire-retardant properties for effective isolation, preventing the influence of cross-layer work. Due to the effective physical isolation between the platforms, the work on each platform can be carried out simultaneously according to actual needs.

[0066] In one or more embodiments, a chimney inner cylinder installation platform-based work method is provided, comprising:

[0067] determining the number of chimney inner cylinders;

[0070] According to the different number of inner cylinders, the platform can be modularly combined (for other numbers of inner cylinders, the same applies), so that the platform is applicable to the assembly requirements of different numbers of inner cylinders.
