Description

Technical Field

[0002] Ventilation duct is the abbreviation of ventilation pipe, which is a metal or non-metal pipe used in ventilation and air-conditioning engineering of industrial and civil buildings.

[0003] The existing ventilation ducts are fixed on the top of the building by brackets and other equipment, and the turning parts of the ventilation ducts are connected by curved pipes to ensure smooth airflow. However, the side wall of the curved pipe is an arc-shaped structure, and it is difficult to adjust the position of the bracket to the bottom of the curved pipe, which is not convenient for hoisting the curved pipe, resulting in gaps at the turning parts of the ventilation ducts, affecting the airflow effect of the ventilation ducts. For this reason, we propose a large-diameter ventilation duct curved pipe hoisting structure. Utility Model Content
