Description

Technical Field

[0001] This utility model belongs to the field of pipe processing technology, specifically relating to an auxiliary device for processing HVAC pipes. Background Technology

[0002] In the field of HVAC engineering, the installation, connection, and fabrication of pipes are crucial. With the continuous advancement of modern building technology and the increasing complexity of HVAC systems, the requirements for the precision, efficiency, and safety of pipe fabrication are also rising. Traditional pipe fabrication methods, especially in the support, positioning, and welding of components such as flanges and elbows, have many shortcomings.

[0003] Firstly, from the perspective of pipe support, traditional support methods mostly employ temporary supports or manual handling. These methods are not only labor-intensive and inefficient, but also make it difficult to guarantee the stability and accuracy of the pipes during processing. Especially when installing large HVAC systems, the length and weight of the pipes are often considerable, posing a significant challenge to operators. Furthermore, the design of temporary supports often lacks flexibility, making it difficult to adapt to the needs of pipes of different diameters and materials, further limiting the efficiency and quality of pipe processing.

[0004] Secondly, regarding pipeline positioning, traditional methods rely heavily on manual measurement and adjustment. This method is not only time-consuming and labor-intensive but also easily affected by human factors, resulting in low positioning accuracy. Especially when welding flanges or elbows, inaccurate pipeline positioning will directly affect the quality and efficiency of the welding, and may even lead to safety hazards in pipeline use. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide an auxiliary device for HVAC pipe processing, which solves the problem that in traditional operation methods, pipe fixing and positioning mostly rely on manual handling and temporary supports, which is not only labor-intensive, but also makes it difficult to ensure that the two ends of the pipe are on the same horizontal plane, causing inconvenience to subsequent welding operations and affecting work efficiency and welding quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary device for processing HVAC pipes, comprising a support plate, a base plate installed on the outer side of the support plate, the base plate having a U-shaped structure, two support shafts symmetrically installed on the support plate, bearings rotatably mounted on the support shafts, a connecting rod welded to one side of the base plate, one end of a hand handle connected to the side of the connecting rod, and a foot pedal rotatably connected to the connecting rod via a pin.

[0007] The beneficial effects of this utility model are as follows: through the two sets of lever structures of base plate, hand handle and foot pedal, the pipeline can be lifted in a labor-saving and safe manner, so that the pipeline is supported by bearings to maintain a stable height and angle; the bearings can roll to support the pipeline, making it convenient for personnel to rotate and adjust the pipeline.

[0008] To make it easier for the pipes to enter the inside of the base plate;

[0009] As a further improvement to the above technical solution: the end of the base plate away from the connecting rod is formed with a chamfered structure.

[0010] The beneficial effects of this improvement are: the chamfered structure of the base plate reduces the thickness of the end of the base plate, allowing the pipe to roll more easily into the interior of the base plate along the slope.

[0011] To provide stable rolling support for pipes of different sizes;

[0012] As a further improvement to the above technical solution: the support plate is provided with a V-groove structure in the direction of the opening end of the bottom plate, and two support shafts are symmetrically arranged on the left and right sides of the V-groove, and the tangent circles of the two bearings are located on the upper side of the V-groove.

[0013] The beneficial effect of this improvement is that the two bearings can provide stable rolling support for pipes of different diameters.

[0014] To ensure uniform force distribution on the support shaft;

[0015] As a further improvement to the above technical solution: the number of bearings is two, and they are arranged opposite to each other on the front and rear sides of the support plate.

[0016] The beneficial effects of this improvement are: the bearings arranged in pairs can stably support the pipeline, and the two bearings arranged in opposite directions can ensure the uniformity of the force on the support shaft and avoid the support shaft from tilting and deforming at one end.

[0017] To ensure the stability of the device's support for the pipeline;

[0018] As a further improvement to the above technical solution: the base plate is a U-shaped steel structure formed by bending flat steel.

[0019] The beneficial effects of this improvement are: the flat structure of the base plate can increase the contact area between the device and the ground, thereby improving the stability of the base plate as a support for the pipeline.

[0020] To make it easier to move the pipe to the inside of the base plate;

[0021] As a further improvement to the above technical solution: the foot pedal is an angle steel structure composed of a pedal part and a push rod part, and the pin is set at the connection between the pedal part and the push rod part.

[0022] The beneficial effect of this improvement is that the operator can step on the pedal and use the lever structure to push the push rod to move the pipeline in a labor-saving way.

[0023] To effectively improve the ease of use of the pedals;

[0024] As a further improvement to the above technical solution: both the push rod part and the pedal part are square plate structures, and the narrow side of the push rod part is set towards the bottom plate, while the narrow side of the pedal part is parallel to the axial direction of the support shaft.

[0025] The beneficial effects of this improvement are: the push rod section pushes the pipe with a smaller contact surface, reducing the frictional resistance between the pipe and the push rod section; the pedal section supports the operator's feet with a larger contact surface, reducing the pressure on the operator's feet.

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0033] Example 1:

[0034] like Figure 1As shown in Figure 4: An auxiliary device for processing HVAC ductwork includes a support plate 1, a base plate 2 mounted on the outer side of the support plate 1, the base plate 2 having a U-shaped structure, two support shafts 3 symmetrically mounted on the support plate 1, bearings 4 rotatably mounted on the support shafts 3, a connecting rod 5 welded to one side of the base plate 2, and a hand handle 6 connected to the side of the connecting rod 5. The connecting rod 5 is rotatably connected to a foot pedal 8 via a pin 7. Through the two sets of lever structures—the base plate 2, the hand handle 6, and the foot pedal 8—the ductwork can be lifted safely and effortlessly. The pipe is supported by bearing 4 to maintain a stable height and angle; bearing 4 can roll to support the pipe, making it easy for personnel to rotate and adjust the pipe. The end of the base plate 2 away from the connecting rod 5 is formed with a chamfered structure. The chamfered structure of the base plate 2 reduces the thickness of the end of the base plate 2, allowing the pipe to roll more easily into the interior of the base plate 2 along the slope. The support plate 1 has a V-groove structure facing the opening end of the base plate 2, and two support shafts 3 are symmetrically arranged on the left and right sides of the V-groove. The tangent circles of the two bearings 4 are located on the upper side of the V-groove. Two bearings 4 provide stable rolling support for pipes of different diameters. These bearings 4 are arranged opposite each other on the front and rear sides of the support plate 1. The two bearings 4, arranged in pairs, stably support the pipes. The opposite arrangement of the two bearings 4 ensures uniform force distribution on the support shaft 3, preventing it from tilting or deforming to one end. The base plate 2 is a U-shaped steel structure formed by bending flat steel. The flat structure of the base plate 2 increases the contact area between the device and the ground, thereby improving the stability of the base plate 2 as a support base for the pipes. The foot pedal 8 is an angle steel structure consisting of a pedal part 81 and a push rod part 82, with a pin 7 located at the connection between the pedal part 81 and the push rod part 82. The operator can step on the pedal part 81 and use the lever structure to effortlessly move the push rod part 82 to propel the pipe. Both the push rod part 82 and the pedal part 81 are square plate structures, with the narrow side of the push rod part 82 facing the base plate 2. The narrow side of the pedal part 81 is parallel to the axial direction of the support shaft 3. The push rod part 82 pushes the pipe with a smaller contact surface, reducing the frictional resistance between the pipe and the push rod part 82. The pedal part 81 provides a larger contact surface to support the operator's feet, reducing pressure on the operator's feet.

[0035] The working principle of this technical solution is as follows: Position the open end of the base plate 2 towards the pipe, insert the bottom end of the base plate 2 into the lower side of the pipe, then step on the pedal 81, causing the pedal 81 to rotate under the support of the pin 7. The push rod 82 pushes the pipe towards the inside of the base plate 2. Then, grasp the upper side of the hand lever 6 and use the hand lever 6 to rotate the base plate 2 90 degrees, causing the pipe to fall onto the support plate 1 under gravity, where it is supported by the rolling bearings 4. Using two of these devices in the above manner to support both ends of the pipe ensures that both ends of the pipe are supported by the rolling bearings 4. At this point, the operator can easily weld flanges or elbows to the pipe ends.
