[0001] The utility model relates to the technical field of fan installation, in particular to an axial flow fan installation structure for smoke exhaust in a steel processing workshop. Background Art
[0002] A large amount of smoke, high temperature and various gases are generated during the production and processing of steel. Axial flow fans are needed to cool the workpieces produced by the steel plant and to exhaust the high-temperature gases in the steel plant. When used in a steel processing workshop, axial flow fans need to be supported and fixed. The axial flow fan mounting structure is a device used to support and fix the axial flow fan. It usually adopts a bracket structure. The bracket structure is made of solid metal materials (such as steel or aluminum alloy) and has sufficient strength and stability to support the weight of the axial flow fan and ensure its safe operation.

Since axial flow fans need to be stable, the bottom plate of the axial flow fan bracket is often supported by thicker metal steel plates, which makes it inconvenient to move the axial flow fan bracket as a whole. When installing the axial flow fan, manual adjustment will consume more physical strength, making it inconvenient to adjust the axial flow fan bracket.

[0033] like Figure 1-5 As shown, an axial flow fan installation structure for smoke exhaust in a steel processing workshop includes a U-shaped frame 5, which is used to connect the axial flow fan body 6. The two ends of the U-shaped frame 5 are rotatably connected to the middle parts of the two sides of the axial flow fan body 6. A collar 8 is integrally provided in the middle of the U-shaped frame 5. The outer wall of the collar 8 and the bottom of the axial flow fan body 6 are detachably installed with a telescopic rod 9, which is used to adjust the inclination angle of the air outlet of the axial flow fan body 6, specifically, to adjust the elevation angle of the air outlet of the axial flow fan body 6;

[0035] The vertical distance from the collar 8 to the connecting line at both ends of the U-shaped frame 5 is greater than half the length of the axial flow fan body 6, so that the U-shaped frame 5 can be folded and stored on the axial flow fan body 6, that is, twisting the U-shaped frame 5 can make it folded to the end of the axial flow fan body 6, which is convenient for storage and transfer. This structure has a protective effect on the U-shaped frame 5 and the collar 8, avoiding deformation caused by the extrusion force during transportation, not destroying the center of gravity of the structure, and maintaining the stability and balance of the structure.

[0039] As a preferred embodiment of the rotating assembly 7 provided by the utility model:
[0040] The rotating assembly 7 includes a driven gear 72 fixed on the collar 8, and the output end of the hydraulic lifting rod 2 passes through the axis of the driven gear 72 and the collar 8, and a bearing member 71 is provided between the hydraulic lifting rod 2 and the through hole of the driven gear 72 and the bearing member 71. The output end of the hydraulic lifting rod 2 and the bottom of the driven gear 72 and the collar 8 are fixedly connected to a support frame 73, and a driving motor 74 is installed on the support frame 73. The output shaft of the driving motor 74 is connected to a driving gear 75, and the driving gear 75 is meshed with the driven gear 72.
[0041] When the driving motor 74 is energized, the driven gear 72 is rotated through the driving gear 75, so that the driven gear 72 rotates the outer ring of the bearing 71. The combined structure of the U-shaped frame 5 and the ring 8 causes the axial flow fan body 6 to twist, thereby adjusting the direction of the air outlet in the circumferential direction.
[0042] As an embodiment of the assembly 3 in the utility model:

[0052] Working principle:
[0053] The U-shaped frame 5 is rotatably installed at the center of the two side walls of the axial flow fan body 6, and the collar 8 is welded at the middle section of the U-shaped frame 5. When transporting the axial flow fan body 6, the U-shaped frame 5 and the collar 8 are folded to one end of the axial flow fan body 6 so as not to squeeze the U-shaped frame 5 and the collar 8. When lifting and transferring the axial flow fan body 6, the U-shaped frame 5 and the axial flow fan body 6 are fixed with screws to realize smooth lifting and transfer of the axial flow fan body 6 and move;

The combined structure of the U-shaped frame 5 and the ring 8 twists the axial flow fan body 6, and can adjust the direction of the air outlet of the axial flow fan body 6 to more accurately align it with the area to be cooled or the area to be blown.
[0056] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
