Description

Technical Field

[0001] This utility model relates to the field of pipe support rotating frame technology, and in particular to a support rotating frame for HVAC pipe processing. Background Technology

[0002] The piping for heating and ventilation systems requires support and rotation during fabrication to facilitate welding, painting, and inspection. Due to the large size of these pipes, manual handling and rotation are labor-intensive and inefficient.

[0003] Existing technologies also include some rotating support frames related to pipe processing, such as the Chinese utility model patent with application number CN202320367692.8, entitled "A Rotary Welding Frame for HVAC Pipes." This device can move pipes via a work frame and rotate them via a rotating assembly, improving pipe installation efficiency. However, it uses clamping blocks and chucks to fix the pipes, making it inconvenient to use and operate when processing large HVAC pipes.

[0004] For example, patent application number CN202421297013.5, entitled "An Adjustable Pipe Support Rotation Device," can support, fix, and rotate pipes while ensuring safety during operation, saving manpower and resources, and providing controllable pipe rotation. However, it mainly utilizes a lifting mechanism that drives a drive roller to rotate via gear transmission, causing the pipe to rotate under the friction between the pipe and the drive roller. The structure is relatively complex, and it is only suitable for pipes within a certain diameter range. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a support and rotation frame for HVAC pipe processing, which can support and rotate HVAC pipes. It has a simple structure and is applicable to a wide range of pipe sizes.

The screw drive structure is located below the rolling support structure, and its drive end is connected to the bottom end of the rolling support structure. The drive assembly is fixed within the frame. The drive assembly drives the screw drive structure to rotate, causing the rolling support structure to move along the sliding assembly at the top of the frame.

[0007] Furthermore, the rolling support structure includes a support plate, roller frames, and rollers.

The slide rail is horizontally fixed to both sides of the upper end of the frame, and the sliders are installed on the upper end of the slide rail through sliding engagement.

[0009] Furthermore, the screw drive structure includes a support beam, a screw seat, a screw, and a screw nut. The support beam is horizontally fixed between the inner sides of the frame. One screw seat is fixed to the top of the support beam, and the other screw seat is fixed to the end of the frame. The two ends of the screw are rotatably mounted on the two screw seats. The screw nut is fixed to the bottom of the support plate. The screw and the screw nut are connected by a threaded connection.

[0017] The purpose of this invention is to address the shortcomings of existing technologies by providing a support rotating frame for HVAC pipe processing.

[0018] Example 1

[0019] This embodiment provides a rotating support frame for HVAC duct fabrication, referring to... Figure 1 As shown, the system includes a frame 1, a drive assembly 3, a screw drive structure 4, a support frame 2, a rolling support structure 6, and a sliding assembly 7. Multiple support frames 2 are symmetrically arranged at the bottom of the frame 1. Two rolling support structures 6 are symmetrically arranged at both ends of the frame 1 for placing HVAC pipes. A sliding assembly 7 is provided between the bottom end of each rolling support structure 6 and the top end of the frame 1. The screw drive structure 4 is located below the rolling support structure 6, and its drive end is connected to the bottom end of the rolling support structure 6. The drive assembly 3 is fixed inside the frame 1. The drive assembly 3 drives the screw drive structure 4 to rotate, causing the rolling support structure 6 to move along the sliding assembly 7 at the top end of the frame 1.

[0020] Reference Figure 2 As shown, the rolling support structure 6 includes a support plate 61, roller frames 62, and rollers 63. The upper end of the support plate 61 is provided with two rows of roller frames 62, and each row of roller frames 62 has three roller frames 62. Each roller frame 62 is rotatably mounted with a roller 63. The roller 63 located in the middle is tilted at a small angle. In this embodiment, the roller 63 in the middle is tilted at 5°, and the rollers 63 located on both sides are tilted inward at 30°. Through the small-angle tilt design of the roller 63 in the middle, the HVAC pipes can rotate better during horizontal movement on the rolling support structure 6.

[0021] Reference Figure 3 As shown, the sliding component 7 includes a support base 71, a slider 72, and a slide rail 73. The support base 71 is symmetrically fixed to the bottom end of the support plate 61. Two sliders 72 are fixed to the bottom end of each support base 71. The slide rail 73 is horizontally fixed to both sides of the upper end of the frame 1. The sliders 72 are installed on the upper end of the slide rail 73 through sliding engagement.

[0022] Reference Figures 2-3 As shown, the lead screw transmission structure 4 includes a support beam 41, a lead screw seat 42, a lead screw 43, and a lead screw nut 44. The support beam 41 is horizontally fixed between the inner sides of the frame 1. One lead screw seat 42 is fixed to the top of the support beam 41, and the other lead screw seat 42 is fixed to the end of the frame 1. The two ends of the lead screw 43 are rotatably mounted on the two lead screw seats 42. The lead screw nut 44 is fixed to the bottom of the support plate 61. The lead screw 43 and the lead screw nut 44 are connected by a threaded connection.

[0023] Reference Figure 3 As shown, the drive assembly 3 includes a motor mounting bracket 31, a geared motor 32, a first synchronous pulley 33, a synchronous belt 34, and a second synchronous pulley 35. The motor mounting bracket 31 is fixed in the center of the support frame 2, and the geared motor 32 is fixed on the motor mounting bracket 31. In this embodiment, the geared motor 32 uses a 220V AC geared motor from the prior art, and its minimum speed is no more than 60 rpm. The first synchronous pulley 33 is fixed on the drive end of the geared motor 32, and the second synchronous pulley 35 is fixed on the end of the lead screw 43. The synchronous belt 34 is sleeved on the first synchronous pulley 33 and the second synchronous pulley 35.

[0024] In use, the HVAC pipe to be processed is placed on the rolling support structure 6, which is supported by two rolling support structures 6. When rotation is required, the two drive components 3 cooperate with the two lead screw transmission structures 4 to drive the first synchronous pulley 33 to rotate via the shaft of the geared motor 32. Through the synchronous belt 34, the lead screw 43 is driven to rotate, which in turn drives the support plate 61 to move horizontally on the slide rail 73 via the slider 72 below it. This causes the two rolling support structures 6 to move horizontally in opposite or opposite directions. During this process, the small-angle tilt of the rollers 63 allows the HVAC pipe to rotate better on the rolling support structure 6, facilitating processing operations such as welding, painting, and inspection of the HVAC pipe. The support rotation frame for HVAC pipe processing of this utility model has a simple structure and is applicable to a wide range of pipe sizes. It should be noted that this utility model is not limited to the processing of HVAC pipes; it can also be applied to similar processing scenarios in adjacent fields such as drainage pipes and municipal pipelines.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
