Description

Technical Field

[0001] The present application relates to the technical field of support structures, and in particular to a support structure for welding fan blades of a cooling tower fan. Background Art

[0002] Cooling tower is a kind of cooling device widely used in various fields. It can generate steam through heat exchange between water and air, and remove excess heat to achieve cooling effect. In layman's terms, cooling tower is a device that lowers water temperature, and its appearance is usually tower-shaped, hence the name cooling tower. Fans are often used in cooling towers to discharge steam.

[0003] The fan blades of the existing cooling tower fan are fixed to the connecting pipe by welding, but the fan blades or the connecting pipe may be easily moved during the welding process, thereby causing the welding position to shift and resulting in the product being scrapped.

[0004] Therefore, a support structure for welding a cooling tower fan blade having the function of preventing deviation is provided. Utility Model Content

[0041] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0042] Embodiment 1:

[0043] Reference Figure 1-6 A support structure 100 for welding fan blades of a cooling tower fan comprises: a connection plate 101, a connection pipe 102, a connection plate 103 and a support assembly for fixing the connection plate 103 to the connection pipe 102. The connection pipe 102 is fixedly connected to the connection plate 101. The connection plate 103 is plugged into the connection pipe 102. The connection pipe 102 comprises a support surface 102a and a first insertion groove 102b, the support surface 102a abuts against the connection plate 103, and the first insertion groove 102b is for the connection plate 103 to be inserted. The fan blade 104 is fixed to the connection plate 103 by screws.

[0044] The support assembly is used to fix the connecting plate 103 to the connecting tube 102, and includes: a first slider 105, a fixing plate 106, a guide tube 107, a guide column 108, a first spring 109, a supporting plate 110, and a push plate 112. The first slider 105 is slidably connected to the connecting plate 103. Specifically, the connecting plate 103 includes a first slide groove 103a along the length direction of the connecting plate 103, and the first slider 105 moves along the first slide groove 103a. The first slider 105 is a T-shaped block. The fixing plate 106 is fixedly connected to the first slider 105.

[0045] The guide tube 107 is fixedly connected to the fixed plate 106. The first slider 105 is located at one end of the fixed plate 106, and the guide tube 107 is located at the other end of the fixed plate 106. The guide post 108 is horizontally slidably connected to the guide tube 107. Specifically, the guide tube 107 includes a guide hole 107a, and the guide post 108 is partially located in the guide hole 107a and moves along the axial direction of the guide hole 107a. The first spring 109 is located in the guide hole 107a, and the two ends of the first spring 109 are fixedly connected to the guide tube 107 and the guide post 108 respectively. The support plate 110 is fixedly connected to the guide post 108. The first spring 109 is located at one end of the guide post 108, and the support plate 110 is located at the other end of the guide post 108.

[0046] The push plate 112 is fixedly connected to the support plate 110. The connecting plate 103 includes a second insertion groove 103b, and the second insertion groove 103b is for the first slider 105 to be inserted. The second insertion groove 103b is connected to the first slide groove 103a. The first slider 105 is inserted into the second insertion groove 103b, and then the push plate 112 is pushed. The movement of the push plate 112 drives the support plate 110 to move, so that the guide column 108 is retracted into the guide hole 107a of the guide tube 107, and then the support plate 110 is moved to the inner hole of the connecting tube 102, and then the push plate 112 is released. Under the action of the first spring 109, the guide column 108 will drive the support plate 110 to abut against the connecting tube 102, thereby fixing the connecting tube 102 and the connecting plate 103, which is more convenient for welding and prevents offset during welding.

[0047] Working process: insert the connecting plate 103 into the first insertion slot 102b, one end of the connecting plate 103 abuts against the supporting surface 102a, then insert the first slider 105 into the second insertion slot 103b, and then push the push plate 112, the push plate 112 moves to drive the supporting plate 110 to move, so that the guide column 108 retracts into the guide hole 107a of the guide tube 107, and then move the supporting plate 110 to the inner hole of the connecting tube 102, and then release the push plate 112, under the action of the first spring 109, the guide column 108 will drive the supporting plate 110 to move. The support plate 110 abuts against the connecting tube 102, thereby fixing the connecting tube 102 and the connecting plate 103, making welding easier and preventing deviation during welding. After welding is completed, the push plate 112 is pushed, and the movement of the push plate 112 drives the support plate 110 to move, so that the support plate 110 is separated from the connecting tube 102, and then the first slider 105 is moved to the second insertion groove 103b position, and the fixing component can be taken out, and the remaining connecting plates 103 can be fixed to the connecting tube 102, which reduces costs and can be reused.
