Description

Technical Field

[0001] This utility model relates to the field of pipeline construction, and in particular to a support frame for cutting HVAC pipes. Background Technology

[0002] In the field of HVAC system construction, ducts are the core carriers of airflow. Their processing accuracy and installation efficiency directly affect the system's operational efficiency and construction cycle. In recent years, with the diversification of building spaces and the improvement of energy-saving standards, rectangular ducts have become the mainstream ventilation duct material due to their advantages such as compact structure and high space utilization. However, cutting the side opening of the duct is a key process for connecting branch pipes and installing functional components, which places higher demands on positioning stability and ease of operation. Traditional processing methods mostly rely on manual hand-held cutting equipment or simple fixing devices, which have problems such as low efficiency, poor cutting accuracy, and prominent safety hazards. Utility Model Content

[0019] When cutting the duct, adjust the length of the telescopic frame according to the length of the duct. Place the angle steel flanges at both ends of the duct into the limiting grooves of the left and right support frames. Then push the telescopic frame to further compress the angle steel flanges at the ends of the duct, positioning the duct. Then lock the casters to limit the length of the duct. Then press the L-shaped limiting plate against the side of the angle steel flange and tighten the limiting nut to limit the width of the duct. After completing the placement and limiting of the duct, the duct can be cut (the side of the duct is cut).

[0020] The beneficial effects of this utility model are as follows: through a simple telescopic adjustment mechanism, it can adapt to ducts of different lengths, while effectively constraining the vibration displacement of the duct during cutting, improving cutting efficiency and cutting accuracy, and ensuring the stability of heavy-duty duct operations.
