AI Technical Summary
Existing HVAC duct laying auxiliary devices are unstable when raised, making them prone to tipping over, and the brackets are inconvenient to replace, failing to easily adapt to different pipe diameters.
The system employs self-locking casters and a hydraulic rod support structure, combined with a motor-driven worm gear system and a two-way lead screw, to achieve stable support for the equipment and convenient replacement of the bracket. The fixed base is raised by the hydraulic rod, and the motor-driven worm gear rotates the two-way lead screw, distributing the center of gravity. The bracket can be disassembled and replaced using a threaded connection.
It improves the stability of HVAC duct laying auxiliary devices and facilitates the replacement of brackets, adapting to the needs of different pipe diameters and ensuring the stability and convenient operation of the equipment during the lifting process.
