[0021] Example

[0022] A prefabricated fixed support for a flanged elbow of a coke oven under-furnace heating gas pipeline includes a fixed base. The fixed base includes a base plate 1 and a support frame 2 vertically mounted on the base plate 1. The base plate 1 and the support frame 2 are respectively provided with bracket fixing points 23 and base plate fixing points 11, used to determine the upper and lower installation positions of the flanged elbow 3. This application provides fixed support for the installation of the flanged elbow of the under-furnace heating gas pipeline by setting the base plate 1 and the support frame 2, facilitating subsequent construction work by on-site workers.

[0023] In some embodiments, in order to improve the installation accuracy of the elbow flange 3, a base plate fixing point 11 and a support frame fixing point 23 are respectively provided on the base plate 1 and the support frame 2. The fixing points are used to position the lower end and the upper end of the elbow flange 3, so that the installation position is more accurate when the workers on site are constructing.

[0024] In some preferred embodiments, the support frame 2 is H-shaped, including two vertical supports 21 perpendicular to the base plate 1, connected by a support plate 22. The support plate 22 is parallel to the base plate 1 and is used to place the elbow flange 3. The spacing of the vertical supports 21 is adapted to the diameter of the elbow flange 3. For example, the fixing base of the elbow flange 3 is made of 25a channel steel welded together, and the vertical supports 21 are provided with support fixing points 23, the positions of which correspond to the bolt holes of the elbow flange 3. Fixing points are set with small steel bars according to the diameter of the starting end of the elbow flange 3.

[0025] Based on the diameter of the elbow flange 3, a prefabricated pallet 22 is constructed. The pallet 22 is made of L100*6 angle steel spliced ​​and welded together. The width of the pallet 22 is 200mm and the height of the pallet 22 is 229mm. The pallet 22 is welded to the vertical bracket 21 to form an H-shaped support frame 2. The support frame 2 is vertically set on the base plate 1. The bracket fixing point 23 is set at the starting end of the elbow flange 3 according to the diameter.

[0026] In some preferred embodiments, the vertical support 21 is bent. By setting the vertical support 21 to a bent shape, this application can increase the contact area between the vertical support 21 and the base plate 1, improve the stability of the fixed support structure, and the increased contact area between the bent support and the elbow flange 3 further improves the installation stability of the bent flange 3.

[0027] It also includes a reinforcing bracket 24, which is arranged parallel to the vertical bracket 21, and a reinforcing plate 25 is provided between the reinforcing bracket 24 and the vertical bracket 21; a base plate fixing point 11 is provided on the base plate 1 for fixing the lower end position of the elbow flange 3. The base plate fixing point 11 is a fixing block, and there are at least 3 fixing blocks. The fixing blocks form a fixing space for the outer edge of the elbow flange 3; the elbow flange 3 is fixed to the base plate 1 and the support frame 2 by welding.

[0028] Example 1

[0029] A prefabricated fixed support for an elbow flange of a coke oven under-heating gas pipeline includes a fixed base. The fixed base includes a base plate 1 and a support frame 2 vertically mounted on the base plate 1. The base plate 1 and the support frame 2 are respectively provided with bracket fixing points 23 and base plate fixing points 11 to determine the upper and lower installation positions of the elbow flange 3. To improve the installation accuracy of the elbow flange 3, base plate fixing points 11 and support frame fixing points 23 are respectively provided on the base plate 1 and the support frame 2. These fixing points are used to position the lower and upper ends of the elbow flange 3, allowing for more precise installation by on-site workers. In some embodiments, the base plate fixing point 21 is a through hole, with the hole at the lower end of the elbow flange 3 corresponding to the position of the base plate fixing point 11. Bolts pass through the elbow flange 3 and the base plate fixing point 11 to fix the lower end of the elbow flange 3 to the base plate 1.

[0030] In the actual manufacturing process, holes 3-4 through holes can be drilled on the base plate 1 according to the position of the elbow flange 3. The flange 3 is fixed to the base plate 1 with bolts for a more secure fit. The upper end of the elbow flange 3 is placed at the base plate fixing point 11, just like in the previous embodiment.

[0031] Example 2

[0032] The installation process of the elbow flange 3 is as follows:

[0033] First, place the starting end of the elbow flange 3 on the support frame fixing point 23, and then place the end of the elbow flange 3 on the base plate fixing point 11 for splicing and welding. The key point of this application is to determine the starting end and the end of the elbow flange 3 by using the support frame fixing point 23 and the base plate fixing point 11. After the starting end of the elbow flange 3 is welded, adjust the elbow flange 3 according to the position of the support plate 22 and weld it firmly.
