Description

Technical Field

[0001] This utility model relates to the field of coke oven modification technology, and in particular to a prefabricated fixed support for a reducing tee of a coke oven under-furnace heating gas pipeline. Background Technology

[0002] When installing reducing tees for coke oven under-furnace heating gas pipelines, a large number of tees of the same type need to be prefabricated on-site. The prefabrication of these reducing tees requires high precision, with particular emphasis on controlling the dimensional accuracy of the tees and the alignment accuracy of the flange bolt holes. Conventional quality control methods are prone to deviations. To meet the requirements for rapid installation of coke oven under-furnace heating gas pipelines and effectively shorten the construction period, it is essential to improve the dimensional accuracy of the pipelines and the alignment accuracy of the flange bolt holes. Therefore, there is an urgent need for a prefabricated fixed support for reducing tees in coke oven under-furnace heating gas pipelines to standardize and unify the prefabrication process, ensuring that the tees are installed correctly in one go, guaranteeing rapid installation, and ensuring that both construction quality and schedule are under control.

[0005] The prefabricated card holder is provided with back supports on both sides.

[0006] The base is made of channel steel spliced ​​together based on the shape of a reducing tee pipe.

[0007] The flange bolt hole fixing end includes a first flange bolt hole fixing end and a second flange bolt hole fixing end, and the position of the first flange bolt hole is opposite to the position of the flange bolt hole on the first pipe in the reducing tee pipe;

[0008] The position of the second flange bolt hole is opposite to the position of the flange bolt hole on the second pipe in the reducing tee.

[0009] The second pipe is provided with a prefabricated clip to fix the position of the second pipe.

[0017] The technical solution of this utility model will be further described clearly and in detail below with reference to the embodiments and accompanying drawings.

[0018] Example

[0019] The reducing tee described in this application is a common pipe fitting in piping systems. Its core feature is that, of the three connections (one inlet and two outlets; or two inlets and one outlet), at least one connection has a different size (diameter) than the others.

[0020] In this application, in order to distinguish the three interfaces, the shortest interface pipe is designated as the first pipe, the medium-length interface pipe as the second pipe, and the longest interface pipe as the third pipe interface.

[0021] like Figures 1-3As shown, this application provides a prefabricated fixed support for a reducing tee of a coke oven under-furnace heating gas pipeline, including a prefabricated reducing tee bracket 1. The prefabricated bracket 1 is spliced ​​from channel steel based on the size of the reducing tee pipeline and is fixed to a base 2. The base 2 has flange bolt hole alignment and fixing ends 3. The flange bolt hole fixing ends 3 are channel steel vertically arranged on the base 2, with corresponding flange bolt holes according to the flange position for positioning the flange with bolts. Back supports 4 are provided on both sides of the prefabricated bracket 1. The base 2 is made of channel steel spliced ​​based on the shape of the reducing tee pipeline. In some preferred embodiments, the channel steel of the prefabricated bracket 1 is spliced ​​from 160a channel steel; the base plate 2 is spliced ​​from 100a channel steel.

[0022] During use, first insert the flanges into each port of the pre-cut reducing tee pipe to fix the flange positions; place the reducing tee pipe with the flanges installed on the base 2, with the back supports 4 located on both sides of the pipe for positioning; then fix the flanges to the flange bolt hole alignment and fixing end 2.

[0023] The fixed support provided in this application focuses on tightening the pipe section and then fastening the flange to the corresponding positioning and fixing end 3 of the flange bolt hole. The position of the reducing tee is determined by the back support 4 of the prefabricated clip 1. After the reducing tee is welded, the flange is welded firmly according to the position of the bolt hole.

[0024] In some preferred embodiments, the end of the first pipe is placed tightly against the bolt hole fixing end 31 of the first flange, with the bolt hole positions corresponding. The flange position is fixed by using bolts that pass through the bolt holes and the bolt hole fixing end 31 of the first flange. The end of the second pipe is placed against the bolt hole fixing end 32 of the second flange, with the bolt hole positions corresponding. The flange position is fixed by using bolts that pass through the bolt holes and the bolt hole fixing end 32 of the second flange. After welding the reducing tee, the flange is welded. Finally, the bolts are removed and the reducing tee is taken out, completing the precise installation of the reducing tee pipe flange.

[0025] In summary, the prefabricated fixed support for reducing tees in the coke oven under-furnace heating gas pipeline provided in this application standardizes and unifies the prefabrication of reducing tees, ensuring that the tees are installed in place at one time, meeting the requirement of rapid installation, and ensuring that both construction quality and schedule are under control.

[0026] Finally, it should be pointed out that the above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
