The invention relates to the technical field of downhole ventilation, in particular to an air duct cloth mesh ring support structure, which includes an arc-shaped plate and a tightening belt. The inner cavity of the hinge ball sleeve is provided with a hinge ball head that matches the hinge ball sleeve. The outer wall of the hinge ball head is fixedly connected to the hook, and the hook extends to the outside of the hinge ball sleeve. The outer wall of the arc-shaped plate is provided with a second A slot and a second slot, and the first slot communicates with the second slot, the ends of the tightening band are fixedly connected to the connecting rope, and the end of the connecting rope away from the tightening band is fixedly connected to the movable ball head , the movable ball head is inserted into the first slot, and the connecting rope passes through the second slot. The overall structure of the air duct cloth mesh ring hanging structure is relatively stable, so that the air duct is not easy to be unhooked and bent during operation. , which ensures the ventilation effect of the air duct, and reduces the difficulty of hanging the air duct, which is convenient for construction personnel to install.
Description
technical field [0001] The invention relates to the technical field of downhole ventilation, in particular to an air duct cloth mesh ring support structure. Background technique [0002] Flexible air ducts are made of canvas, artificial leather, rubber, and plastic leather. They are also called positive pressure air ducts mainly because of the press-in ventilation. The hanging of the flexible air duct should be flat, straight, tight, stable, and turn slowly. If the flexible air duct is not hung properly, it will increase the local resistance and affect the ventilation effect. In order to ensure the quality of ventilation, construction workers usually The anchor rod is installed underground, and the collar is set on the outside of the air duct and hooked to the anchor rod with a hook. It is troublesome to hoist, and the flexible air duct often shakes during ventilation, causing the hook to fall off from the anchor rod. Once it falls off, the ventilator is prone to bending an...
