Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a bracket for fixing a fan. Background Technology

[0002] Large industrial fans are widely used in industrial production, warehousing and logistics, and large venues due to their wide coverage and low energy consumption. Currently, traditional hanger structures typically use rigid connections, fixing the fan to the end of the hanger rod with bolts, forming a single vertical suspension. This structure has significant drawbacks in practical use. Since direct connection to the factory ceiling is not possible, it needs to be installed on H-beams. In some factory areas, the installation point on the beam may even be perpendicular to the hanger rod. Existing fixed hangers cannot adjust the installation angle according to the installation environment, severely limiting their effectiveness. Utility Model Content

[0003] To address the problem that existing fan mounting brackets cannot adjust the installation angle according to the installation environment, this invention provides a fan mounting bracket for fixing fans.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A fan mounting bracket includes a base plate, clamping plates, a first bracket, and a second bracket. The clamping plates are disposed on the left and right sides of the top of the base plate, and a gasket is provided between the clamping plates and the base plate. The first bracket is fixedly connected to the bottom of the base plate, and the second bracket is connected to the first bracket. The second bracket rotates relative to the first bracket to adjust its angle relative to the first bracket.

[0006] Furthermore, the substrate is fixedly connected to the clamp and gasket by bolts.

[0007] Furthermore, the clamp is bent and includes a first section and a second section. The first section is provided with a plurality of bolt holes, each bolt hole being adjacent to the connection between the first section and the second section.

[0008] Furthermore, the first hanger has a rectangular cross-section, the second hanger has a U-shaped cross-section, and both the left and right side walls of the second hanger have fixing holes and arc-shaped holes, with the fixing holes located above the arc-shaped holes.

[0009] Furthermore, the first hanger and the second hanger are fixed together by means of the fixing hole, the arc hole and the bolt, and the second hanger rotates relative to the first hanger with the fixing hole as the origin and the arc hole as the path.

[0010] Furthermore, the first hanger includes a pair of triangular first connecting plates, the second hanger includes a pair of triangular second connecting plates, and the first hanger and the second hanger are connected by a connector.

[0011] Furthermore, the connector is cross-shaped and includes a first rotating shaft and a second rotating shaft. The left and right ends of the first rotating shaft are fixedly connected to the first connecting plate by bolts, and the front and rear ends of the second rotating shaft are fixedly connected to the second connecting plate by bolts.

[0012] Furthermore, the bottom of the second hanger is fixed with a connecting pipe, and the connecting pipe is provided with several bolt holes.

[0013] The beneficial effects of this utility model are: the second hanger can rotate relative to the first hanger, which allows for flexible adjustment of the fan's installation angle according to the installation environment, avoiding limitations imposed by the installation environment during fan installation and improving the flexibility and convenience of fan installation.

[0022] This utility model discloses a bracket for fixing a fan. The first embodiment of this utility model is described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, a fan mounting bracket includes a base plate 1, clamping plates, a first hanger 4, and a second hanger 5. The base plate 1 has several elongated holes to accommodate various widths of H-beams 8. There are two clamping plates 3, respectively located on the left and right sides of the top of the base plate 1. The clamping plates 3 are bent, comprising a first section and a second section, with an obtuse angle between them. The first section has several bolt holes located near the connection point between the first and second sections. A gasket 2 is placed between the clamping plate 3 and the base plate 1. Both the base plate 1 and the gasket 2 have several bolt holes, and the clamping plates 3 and gasket 2 are fixedly connected to the base plate 1 by bolts.

[0024] like Figure 2 As shown, the first hanger 4 is fixed to the bottom of the substrate 1, and the cross-section of the first hanger 4 is rectangular. The cross-section of the second hanger 5 is U-shaped, and fixing holes and arc-shaped holes 6 are provided on the left and right side walls of the second hanger 5, with the fixing holes located above the arc-shaped holes 6. The first hanger 4 and the second hanger 5 are fixedly connected by bolts through the fixing holes, arc-shaped holes 6, and the second hanger 5 rotates relative to the first hanger 4 with the fixing holes as the origin and the arc-shaped holes 6 as the path. A connecting pipe 7 is fixedly connected to the bottom center of the second hanger 5, and the connecting pipe 7 is provided with several bolt holes.

[0025] like Figure 3As shown, the workers use bolts to fix the fixing holes and arc-shaped holes 6 on the second hanger 5 to the first hanger 4. H-beams 8 are installed as crossbeams in the factory. When installing the fan on the H-beams 8, the workers first place the base plate 1 at the bottom of the lower flange of the H-beam 8. The base plate 1 has several elongated holes; the workers can select appropriate elongated holes based on the width of the lower flange of the H-beam 8 to fit with the bolts for fixation. Then, the workers place a shim 2 on the base plate 1 and a clamping plate 3 on top of the shim 2. The first section of the clamping plate 3 is placed on top of the lower flange of the H-beam 8, and the end face of the clamping plate 3 needs to be close to the web of the H-beam 8 to ensure sufficient contact area between the clamping plate 3 and the H-beam 8. At this time, the second section of the clamping plate 3 is located on top of the shim 2. Finally, bolts and washers are used to fix the clamping plate 3, shim 2, and base plate 1, achieving clamping and fixation with the lower flange of the H-beam 8. The staff then installed the fan body onto the hanger 9, and fitted the upper end of the hanger 9 onto the connecting pipe 7, securing it with bolts. When the angle needs to be adjusted, the staff loosened the inner bolts located in the fixing hole and the arc-shaped hole 6. The staff could then rotate relative to the first hanger 4 with the fixing hole as the origin and the arc-shaped hole 6 as the path. After rotating to the appropriate position, the bolts were tightened again to adjust the angle of the fan body.

[0026] The second embodiment of this utility model will be described in detail below with reference to the accompanying drawings. In this embodiment, except for the structures of the first hanger 4 and the second hanger 5, which are different from those in the first embodiment, the rest of the structures are the same.

[0027] like Figure 4 As shown, the first hanger 4 includes a pair of first connecting plates, the tops of which are fixed to the bottom of the base plate 1. The second hanger 5 has a U-shaped cross-section, and its left and right sidewalls are second connecting plates, both of which are triangular. The first hanger 4 and the second hanger 5 are connected by a connector 10. Figure 7 As shown, the connector 10 is cross-shaped and includes a first rotating shaft and a second rotating shaft, which are arranged perpendicularly to each other. The left and right ends of the first rotating shaft are fixedly connected to the first connecting plate by bolts, and washers are also provided between the bolts and the first connecting plate. The front and rear ends of the second rotating shaft are fixedly connected to the second connecting plate by bolts, and washers are also provided between the bolts and the second connecting plate.

[0028] Combination Figure 5 and Figure 6As shown, during use, the operator places the connector 10 between the first hanger 4 and the second hanger 5, and fixes it to the first hanger 4 and the second hanger 5 respectively with bolts. H-beams 8 are installed in the factory as crossbeams. When installing the fan on the H-beams 8, the operator first places the base plate 1 at the bottom of the lower flange of the H-beams 8. The base plate 1 has several elongated holes, and the operator can select appropriate elongated holes according to the width of the lower flange of the H-beams 8 to fit with the bolts for fixation. Then, the operator places a shim 2 on the base plate 1 and a clamping plate 3 on top of the shim 2. The first section of the clamping plate 3 is placed on top of the lower flange of the H-beams 8, and the end face of the clamping plate 3 needs to be close to the web of the H-beams 8. At this time, the second section of the clamping plate 3 is located on top of the shim 2. Finally, bolts are used to fix the clamping plate 3, the shim 2, and the base plate 1 together, achieving clamping and fixation with the lower flange of the H-beams 8. The workers then installed the suspension rod 9 on the fan body and fitted the upper end of the suspension rod 9 onto the connecting pipe 7, securing it with bolts. When the angle needs to be adjusted, the workers can loosen the bolts on the first and second rotating shafts, allowing the second hanger 5 to rotate relative to the first hanger 4 in two directions. After rotating to the appropriate position, the bolts are tightened again to adjust the angle of the fan body.

[0029] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
