Description

Technical Field

[0001] This utility model belongs to the field of shipbuilding technology, and specifically relates to an adjustable shock-absorbing base for axial flow fans. Background Technology

[0002] During shipbuilding, most manufacturers rely solely on the clamping force formed by the ducts at both ends of the axial flow fan as the primary means of fixing the fan, lacking a dedicated base for effective support. This results in strong vibrations in the ducts. Even if some companies pay attention to the fan fixing issue, the bases they install often require re-cutting due to various errors before installation. The adjustable damping base described in this invention utilizes an adjusting plate to control the base length, effectively reducing construction errors and ensuring the base fits snugly against the fan body. Furthermore, the damping blocks at the end of the base absorb the vibration energy generated during fan operation, reducing its impact on the ship's structure and ductwork. Utility Model Content

[0003] To address the aforementioned issues, this invention provides an adjustable vibration damping base for axial flow fans, which can effectively control the length of the fan base, thereby reducing situations where the base cannot match the fan due to errors in the manufacturing of the equipment body or the base.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An adjustable damping base for an axial flow fan includes two spaced and mirror-symmetrically arranged clamping plates, which are vertically arranged. An adjustable component is connected to the upper part of the two clamping plates, and the two clamping plates move towards each other or away from each other under the drive of the adjustable component. The two clamping plates are respectively connected to flanges at both ends of the axial flow fan.

[0006] Furthermore, the adjustable component includes two mirror-symmetrically arranged U-shaped parts, with their open ends facing each other and the two U-shaped parts slidably connected.

[0007] Furthermore, the opposite ends of the two U-shaped pieces are slidably connected.

[0008] Furthermore, two connecting plates are fixed relative to each other on the outer or inner side of the joint of the two U-shaped parts, with the length direction being the same as that of the side arm. The first end of the length direction of the two connecting plates is fixedly connected to both sides of the same U-shaped part, and the second end of the length direction of the two connecting plates extends into the length range of the side arm of another U-shaped part. The connecting plates and the U-shaped parts that are not connected to them are moved and connected towards or away from each other.

[0009] Furthermore, a strip-shaped hole is provided on the side arm of the connecting plate and the U-shaped component that is not connected to it. The length direction of the strip-shaped hole is parallel to the length direction of the connecting plate. The connecting plate and the U-shaped component are detachably connected by bolts.

[0010] Furthermore, at the corners of both U-shaped parts, there are vertically upward extending base support legs. A pad is fixed at the top of the base support leg. The pad is drilled with screw holes corresponding to the connecting holes on the shock-absorbing pad at the predetermined position. The pad is connected to the shock-absorbing pad that is already in the predetermined position by bolts.

[0011] Furthermore, the clamping plate is provided with a groove with the same shape as the outer wall of the axial flow fan. In use, the axial flow fan is embedded in the groove, and the clamping plate is located inside the flanges at both ends of the axial flow fan.

[0012] Furthermore, the U-shaped component and the base support leg are made of angle steel.

[0013] This utility model discloses an adjustable vibration damping base for axial flow fans. Through the adjustment of the adjustment plate, errors caused by the manufacturing process of the base can be effectively eliminated. Construction personnel can adjust the length of the base to better match the axial flow fan, reducing the amount of trimming and improving assembly efficiency. By setting vibration damping blocks on the base, the impact of fan vibration on the hull structure and ductwork can be effectively eliminated, optimizing the working environment of the ship during navigation. The base can be disassembled with bolts, avoiding the need for hot work during fan repairs and enhancing the safety and convenience of equipment disassembly. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1-3 As shown, an adjustable damping base for an axial flow fan includes two spaced and mirror-symmetrically arranged clamping plates 1. The two clamping plates 1 are vertically arranged, and an adjustable component is connected to the upper part of the two clamping plates 1. The two clamping plates 1 move towards each other or away from each other under the drive of the adjustable component. The two clamping plates 1 are respectively connected to the flanges at both ends of the axial flow fan.

[0020] Understandably, by making the distance between the two clamping plates 1 adjustable, errors caused by the base manufacturing process can be effectively eliminated. Construction workers can better match the axial flow fan by scaling the base length, reducing the amount of trimming work and improving assembly efficiency.

[0021] Furthermore, the adjustable component includes two mirror-symmetrically arranged U-shaped parts 2, with their open ends facing each other, and the two U-shaped parts 2 are slidably connected.

[0022] In some embodiments, the opposite ends of the two U-shaped pieces 2 are slidably connected.

[0023] More specifically, two connecting plates 3 are fixed relative to each other on the outer or inner side of the joint of the two U-shaped parts 2, with the length direction being the same as that of the side arm. The first end of the length direction of the two connecting plates 3 is fixedly connected to both sides of the same U-shaped part 2, and the second end of the length direction of the two connecting plates 3 extends into the length range of the side arm of another U-shaped part 2. The connecting plates 3 and the U-shaped parts 2 that are not connected to them move towards or away from each other.

[0024] In this embodiment, a strip-shaped hole 21 is provided on the side arm of the connecting plate 3 and the U-shaped component 2 that is not connected to it. The length direction of the strip-shaped hole 21 is parallel to the length direction of the connecting plate 3. The connecting plate 3 and the U-shaped component 2 are detachably connected by bolts 4. In this embodiment, the strip-shaped hole 21 is an oblong hole. When it is necessary to change the length of the base, the allowance of the oblong hole is used to make up for the error caused by manufacturing and other reasons, so that the base can be better matched with the wind turbine.

[0025] Of course, in other embodiments, the two U-shaped pieces 2 can also be slidably connected in other ways, for example, the opposite ends of the two U-shaped pieces 2 can also be connected by a sliding track.

[0026] Furthermore, at the corners of both U-shaped parts 2, there are vertically upward extending base support legs 5. A pad 6 is fixed at the top of the base support leg 5. The pad 6 is drilled with screw holes corresponding to the connecting holes on the shock-absorbing pad 7 at the predetermined position. The pad 6 is connected to the shock-absorbing pad 7, which is already in the predetermined position, by bolts 4.

[0027] Furthermore, the clamping plate 1 is provided with a groove 11 that has the same shape as the outer wall of the axial flow fan. In use, the axial flow fan is embedded in the groove 11, and the clamping plate 1 is located inside the flanges at both ends of the axial flow fan.

[0028] Furthermore, the U-shaped component 2 and the base support leg 5 are made of angle steel.
