Description

Technical Field

[0001] This utility model belongs to the field of fan silencer processing technology, and in particular relates to an auxiliary support for welding fan silencers. Background Technology

[0002] Fan silencers are devices used to reduce the aerodynamic noise (airflow noise) and mechanical noise generated by fans during operation. They are widely used in industries, buildings, HVAC systems and other fields. Fan silencers generally consist of an air inlet, elbow, silencer chamber, silencer body and outlet. When welding its circular outer shell, users usually use two wheel frames to support it to facilitate welding on its surface.

[0003] Currently, most fan silencer welding uses a rotating frame for support. When welding different positions of the fan silencer, the distance between the two rotating frames needs to be adjusted. After adjustment, the position of the rotating frame is prone to shift, which can lead to poor contact between the rotating wheel at the top of the rotating frame and the circular shell when it is on top. Therefore, an auxiliary support for fan silencer welding is needed. The distance between the two rotating frames can be adjusted by adjusting the structure to avoid the position of the rotating frame shift after the distance is adjusted, thus ensuring the stability of the circular shell on top of the rotating frame. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary support for welding a fan silencer, which allows for adjustment of the distance between the two rotating frames through an adjustable structure, preventing the rotating frames from shifting after the distance is adjusted, and ensuring the stability of the circular outer shell on the top of the rotating frames, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An auxiliary support for welding a fan silencer includes a fixed frame 1. Two symmetrical mounting frames are fixedly connected to the top of the fixed frame 1. A sliding groove is opened on the top of the mounting frame. A support frame 1 is fixedly connected to the top of the two mounting frames. A support frame 2 is provided on the top of the two mounting frames. Two symmetrical slides are fixedly connected to the bottom of the support frame 2. The slides are located in the inner cavity of the sliding groove. Three identical rotating wheels are rotatably connected to the inner cavity of the slides. The rotating wheels roll on the top of the fixed frame 1. Limiting strips are fixedly connected to the front and back of the slides. The limiting strips are adapted to the sliding groove. A threaded sleeve is fixedly connected to the bottom of the support frame 2. The fixed frame 2 is fixedly fixed to the top of the fixed frame 1. A connecting sleeve is fixedly connected to the top of the fixed frame 1. A threaded rod is rotatably connected between the fixed frame 2 and the connecting sleeve. The threaded rod passes through the threaded sleeve and is threadedly connected to the threaded sleeve. A turntable is fixedly connected to the right side of the threaded rod through the fixed frame 2.

[0006] Preferably, the bottom of the fixing frame one is fixedly connected with four symmetrical raised supports, and the raised supports are U-shaped.

[0007] Preferably, the first fixing frame is U-shaped, the mounting frame is channel steel, the first support frame is parallel to the second support frame, and the slide slides in the inner cavity of the slide groove.

[0008] Preferably, the bottom of the second support frame is not in contact with the top of the mounting frame, and the top of the second fixing frame is fixedly connected to the bottom of the first support frame.

[0009] Preferably, the second fixing frame is U-shaped, and a handle is fixedly connected to the surface of the turntable, with the end of the handle away from the turntable being spherical.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model rotates the turntable to make the threaded rod and threaded sleeve move. Through the limiting of the sliding groove and the limiting strip, the slide carriage slides on the top of the fixed frame one via the rotating wheel, so that the support frame two moves on the top of the fixed frame one. This achieves the purpose of adjusting the distance between the two rotating wheel frames through the adjustment structure, avoiding the displacement of the rotating wheel frame position after the distance is adjusted, and ensuring the stability of the circular shell on the top of the rotating wheel frame.

[0012] 2. By setting up the raised frame, the contact area between the fixed frame and the ground is reduced, avoiding the fixed frame from being directly in contact with the ground and being affected by ground moisture and corrosive substances, thus extending the service life of the fixed frame.

[0022] Figure 1-4This invention illustrates an embodiment of an auxiliary support for welding a fan silencer, comprising a fixed frame 1. Two symmetrical mounting frames 2 are fixedly connected to the top of the fixed frame 1. Each mounting frame 2 has a sliding groove 3 on its top. A support frame 4 is fixedly connected to the top of each mounting frame 2. A second support frame 5 is provided on the top of each mounting frame 2. The bottom of the second support frame 5 is not in contact with the top of the mounting frame 2. The top of the fixed frame 10 is fixedly connected to the bottom of the support frame 4. Two symmetrical slides 6 are fixedly connected to the bottom of the second support frame 5. The slides 6 are located within the sliding groove 3. Three identical rotating wheels 7 are rotatably connected to the inner cavity of the slides 6. The top of the fixed frame 1 rolls, and the front and back of the slide 6 are fixedly connected to the limit strips 8, which are adapted to the slide groove 3. The bottom of the support frame 2 5 is fixedly connected to the threaded sleeve 9, and the top of the fixed frame 11 is fixedly connected to the fixed frame 2 10, which is U-shaped. The surface of the turntable 13 is fixedly connected to the handle, and the end of the handle away from the turntable 13 is spherical. The top of the fixed frame 11 is fixedly connected to the connecting sleeve 11, and the fixed frame 2 10 and the connecting sleeve 11 are rotatably connected to the threaded rod 12.

The right side of the threaded rod 12 passes through the fixed frame 2 10 and is fixedly connected to the turntable 13.

[0023] Working principle: When using this utility model, the user rotates the turntable 13 to make the threaded rod 12 and the threaded sleeve 9 move threadedly. Through the limiting of the sliding groove 3 and the limiting strip 8, the slide 6 slides on the top of the fixed frame 1 via the rotating wheel 7. This causes the slide 6 to drive the support frame 2 5 to move above the fixed frame 1, adjusting the distance between the support frame 1 4 and the support frame 2 5. This prevents the position of the rotating wheel frame from shifting after the distance is adjusted, ensuring the stability of the circular shell on the top of the rotating wheel frame. By setting the shim 14, the shim 14 reduces the contact area between the fixed frame 1 and the ground, preventing the fixed frame 1 from directly contacting the ground and being affected by ground moisture and corrosive substances, thus extending the service life of the fixed frame 1.

[0024] In summary: This auxiliary support for welding the fan silencer, by rotating the turntable 13, causes the threaded rod 12 and the threaded sleeve 9 to move threadedly. Through the limiting of the sliding groove 3 and the limiting strip 8, the slide 6 slides on the top of the fixed frame 1 via the rotating wheel 7, so that the support frame 2 5 moves on the top of the fixed frame 1. This achieves the purpose of adjusting the distance between the two rotating wheel frames through the adjustment structure, avoiding the displacement of the rotating wheel frame position after the distance is adjusted, and ensuring the stability of the circular shell on the top of the rotating wheel frame.
