Abstract

The invention discloses an air duct orifice diameter and orientation automatic adjusting trolley based on double clamping plates. The trolley comprises a trolley body, a travelling mechanism, an orifice diameter and orientation adjusting mechanism which adjusts the diameter and orientation of an adjusted flexible air duct orifice, and an adjusting state detection unit. The orifice diameter and orientation adjusting mechanism comprises a left side adjusting piece and a right side adjusting piece. The left side adjusting piece comprises a left arc supporting rod, a left side supporting plate, a left side clamping plate, a rear hinge base, and a left telescopic hydraulic cylinder. The right side adjusting piece comprises a right arc supporting rod, a right side supporting plate, a right side clamping plate, a front hinge base, and a right telescopic hydraulic cylinder. The left side clamping plate and the right side clamping plate are bilaterally symmetrically arranged. The adjusting state detection unit comprises a rotational angle detection unit and a distance detection unit which detects the distance between the left side clamping plate and the right side clamping plate. The air duct orifice diameter and orientation automatic adjusting trolley is simple in structure, rational in design, simple in use and operation, and good in use effect, and can simply adjusts the orifice diameter and orientation of the flexible air duct.

Description

technical field [0001] The invention belongs to the technical field of tunnel ventilation construction, and in particular relates to a vehicle for automatically adjusting the caliber and orientation of an air duct based on double clamping plates. Background technique [0002] At present, the tunnel construction ventilation at home and abroad mostly adopts the pipeline press-in ventilation method, and an axial flow fan is installed outside the tunnel entrance. The fresh air is sent to the tunnel excavation face, and the dirty air in the tunnel is expelled out of the tunnel along the excavated tunnel body under the squeeze of the fresh air sent into the tunnel. When the tunnel is long, multiple axial flow fans are used in parallel and in series to increase the air volume and air supply distance. In the actual construction process, after the blasting is completed, the concentration of blast smoke and harmful gases produced by blasting and transportation in the cave is relative...
