Description

Technical Field

[0001] The utility model relates to the technical field of HVAC pipeline installation, in particular to a HVAC engineering pipeline installation docking device. Background Art

[0002] HVAC is an integral part of a building, including heating, ventilation, and air conditioning. In the HVAC regulation process, HVAC pipes are an indispensable transmission medium. Due to the different distances between heating or cooling equipment and the areas to be regulated, HVAC pipes often need to be spliced.

[0003] When existing HVAC pipes are docked, they are difficult to fix due to their own gravity. Most HVAC pipe connection ports are equipped with multiple bolt ports. The bolt ports between the two pipes need to be aligned before they can be fixed with bolts, but it is difficult to align the pipe docking ports using manpower.

[0004] A Chinese patent discloses a docking device for HVAC pipe installation (authorization announcement number CN215789712U). This patented technology fixes the HVAC pipe to a movable plate using a clamping device. The height of the HVAC pipe can be adjusted by a lifting device, and the HVAC pipe can be moved left and right by rotating a screw. This makes it easy to align and fix the docking ports of the two HVAC pipes, facilitating subsequent connection and improving installation efficiency.

[0005] However, it has certain disadvantages: it can only drive the clamped HVAC pipes to be docked and installed with the HVAC pipes distributed horizontally on the ground, and cannot drive the clamped HVAC pipes to be docked and installed with the HVAC pipes distributed vertically on the wall. Therefore, its scope of application is narrow and its applicability needs to be improved. Utility Model Content
