[0002] In the foundry industry, heating furnaces are used to heat castings or casting raw materials. For heating furnaces, heating furnace pipes are one of their important components.

[0003] At present, the furnace tubes in the heating furnace pipeline are generally fixed and positioned by installing multiple circular hole plates. However, when the circular hole plates are installed and moved, the friction resistance between the circular hole plates and the furnace tubes is relatively large. During the rigid installation, the furnace tubes and the circular hole plates are easily deflected, which can easily cause the furnace tubes to twist or wear. Utility Model Content

[0004] In view of the deficiencies and defects in the prior art, the purpose of the present invention is to provide a heating furnace pipe structure, which solves the problem in the prior art that when the circular hole plate is installed and toggled, the friction resistance between the circular hole plate and the furnace tube is large, which easily causes the furnace tube to twist or wear when rigidly installed.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a heating furnace pipeline structure, comprising a plurality of U-shaped furnace tubes and a plurality of circular hole plates, and also comprising a fixed end plate and an outer flange plate, wherein the fixed end plate and the outer flange plate are connected by a connecting tube, and three small connecting tubes are provided on the outside of the connecting tube, and a plurality of first mounting holes corresponding to the furnace tubes are provided on the fixed end plate, and an insulating ring that allows the furnace tubes to pass through is fixed on the inner wall of the first mounting hole, and a plurality of second mounting holes are opened on the circular hole plate at positions corresponding to the furnace tubes, and the plurality of second mounting holes are connected by a thin flow channel inside the circular hole plate, and a refueling hole that can communicate with the outside world is provided on the outside of one of the second mounting holes on the circular hole plate.

[0006] As a further improvement of the present invention, a limiting hole is provided in the center of the circular hole plate, and a limiting column matching the positioning hole is also included. Multiple circular hole plates are connected through a limiting column that can be plugged into the limiting hole.

[0007] As a further improvement of the present invention, the limiting hole is connected to one of the second mounting holes through a small flow channel.

[0008] As a further improvement of the present invention, a circle of fixing holes is provided on the fixed end plate.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] 1. By arranging a fixed end plate, a connecting tube and an outer flange plate, the furnace tube can be fixedly installed at the end, which is convenient for docking and connecting the furnace tube with other components; by arranging the circular hole plate, multiple furnace tubes can be limited and fixed to avoid the furnace tubes from being dispersed, and a second mounting hole is provided on the circular hole plate, so that the furnace tube can be inserted into the second mounting hole, which is convenient for the circular hole plate to limit and position the furnace tube, and the second mounting holes are connected through a thin flow channel inside the circular hole plate, and a refueling hole that can communicate with the outside is provided on the outer side of one of the second mounting holes of the circular hole plate. When installing and shifting the circular hole plate, lubricating oil can be injected from the refueling hole, and the lubricating oil flows into each second mounting hole in turn, thereby lubricating the circular hole plate and the furnace tube, reducing the friction between the circular hole plate and the furnace tube, thereby facilitating the insertion of the furnace tube and the shifting of the circular hole plate, not only reducing the wear and damage of the furnace tube, but also saving effort, and avoiding the problem of furnace tube twisting caused by forceful and blunt pushing of the circular hole plate or the furnace tube.

[0011] 2. By providing a limiting hole in the center of the circular hole plate and a pluggable limiting column, when moving the circular hole plate or inserting the furnace tube into the circular hole plate, the limiting column can be inserted into the limiting hole of the circular hole plate first, thereby limiting the multiple circular hole plates, ensuring that the corresponding second mounting holes on the circular hole plates are aligned, avoiding deflection and twisting between the circular hole plates, thereby facilitating the insertion of the furnace tube or avoiding twisting and deformation of the furnace tube.

[0012] 3. By connecting the limiting hole to one of the second mounting holes through a small flow channel, the lubricating oil can flow from the second mounting hole into the limiting hole, so as to lubricate the limiting hole and the limiting column and reduce the friction between the limiting hole and the limiting column.

[0023] The embodiment of the utility model discloses a heating furnace pipeline structure. Figure 1 、 Figure 2 and Figure 3 A heating furnace pipeline structure includes multiple U-shaped furnace tubes 1 and multiple circular hole plates 2, and also includes a fixed end plate 3 and an outer flange plate 4. The fixed end plate 3 and the outer flange plate 4 are connected by a connecting tube 5. A circle of fixing holes 14 is opened on the fixed end plate 3, and three small connecting tubes 6 are provided on the outer side of the connecting tube 5. The fixed end plate 3 is provided with multiple first mounting holes 7 corresponding to the furnace tubes 1. The inner wall of the first mounting hole 7 is fixed with an insulation ring that allows the furnace tube 1 to pass through. The insulation ring can be spot-welded and fixed to the furnace tube 1, such as Figure 2 、 Figure 4 and Figure 5 As shown, the circular plate 2 is provided with a plurality of second mounting holes 8 at positions corresponding to the furnace tube 1. Figure 4 and Figure 6 As shown, multiple second mounting holes 8 are connected by thin channels 9 within the circular orifice plate 2. A fueling hole 10, which is accessible to the outside, is provided on the circular orifice plate 2 outside one of the second mounting holes. To facilitate the fabrication of the thin channels 9, the circular orifice plate 2 can be fabricated by welding two steel plates together. For example, half of the thin channels 9 and fueling hole 10 can be symmetrically machined on each steel plate, and then the two steel plates can be welded together to form a complete thin channel 9 and fueling hole 10.

[0024] In addition, if Figure 4 and Figure 5As shown, the circular hole plate 2 is provided with a limiting hole 11 in the center, and also includes a limiting column 12 that matches the positioning hole. Multiple circular hole plates 2 are connected by a limiting column 12 that can be plugged into the limiting hole 11. When the circular hole plate 2 is moved or the furnace tube 1 is inserted into the circular hole plate 2, the limiting column 12 can be inserted into the limiting hole 11 of the circular hole plate 2 first, thereby limiting the multiple circular hole plates 2 and ensuring that the corresponding second mounting holes 8 on the circular hole plates 2 are aligned, avoiding deflection and twisting between the circular hole plates 2, thereby facilitating the insertion of the furnace tube 1 or avoiding the distortion of the furnace tube 1. In addition, as Figure 4 and Figure 6 As shown, the limiting hole 11 is connected to one of the second mounting holes 8 through a small flow channel 13, which facilitates the lubricating oil to flow from the second mounting hole 8 into the limiting hole 11, so as to lubricate the limiting hole 11 and the limiting column 12 and reduce the friction between the limiting hole 11 and the limiting column 12.

[0025] The utility model is provided with a fixed end plate 3, a connecting tube 5 and an outer flange plate 4, so that the furnace tube 1 can be inserted and fixed at the end, which is convenient for the butt connection between the furnace tube 1 and other components; by providing a circular hole plate 2, multiple furnace tubes 1 can be limited and fixed to avoid the furnace tubes 1 from being scattered. A second mounting hole 8 is provided on the circular hole plate 2, so that the furnace tube 1 can be inserted into the second mounting hole 8, which is convenient for the circular hole plate 2 to limit and position the furnace tube 1, and the second mounting holes 8 are connected through a thin flow channel 9 inside the circular hole plate 2, and one of the circular hole plate 2 is provided with a thin flow channel 9. A refueling hole 10 that can communicate with the outside is provided on the outside of the second mounting hole. When installing and shifting the circular hole plate 2, lubricating oil can be injected from the refueling hole 10, and the lubricating oil flows into each second mounting hole 8 in turn, thereby lubricating the circular hole plate 2 and the furnace tube 1, reducing the friction between the circular hole plate 2 and the furnace tube 1, and facilitating the insertion and shifting of the furnace tube 1, which not only reduces the wear and damage of the furnace tube 1, but also saves effort and avoids the problem of torsion of the furnace tube 1 caused by forceful and blunt pushing of the circular hole plate 2 or the furnace tube 1.
