The invention discloses a movable adjusting rack for the air direction of a flexible air pipe opening. The movable adjusting rack comprises a movable base, a traveling mechanism, a traveling driving motor, a vertical sleeve disposed on the movable base, an inner adjusting rod arranged in the vertical sleeve in a sleeved mode, an electric rotary seat mounted on the inner adjusting rod and a horizontal mounting plate disposed on the electric rotary seat. A transverse groove for mounting a horizontal sliding way is formed in the upper portion of the horizontal mounting plate. A left limiting plate for limiting a left hydraulic cylinder is disposed on the upper portion of the left end of the horizontal mounting plate and a right limiting plate for limiting a right hydraulic cylinder is disposed on the upper portion of the right end of the horizontal mounting plate. The horizontal sliding way is provided with a left sliding block and a right sliding block. The left sliding block is provided with a left supporting rod of which the upper portion is provided with a left clamping plate. The right sliding block is provided with a right supporting rod of which the upper portion is provided with a right clamping plate. The left clamping plate and the right clamping plate are symmetrically arranged. The movable adjusting rack for the air direction of the flexible air pipe opening is simple in structure, reasonable in design, easy and convenient to use and operate, good in using effect and capable of easily and conveniently adjusting the air supply direction of the flexible air pipe opening.
Description
technical field [0001] The invention belongs to the technical field of tunnel ventilation construction, and in particular relates to a movable flexible air duct opening air direction adjusting frame. 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, once the flexible air duct in the tunnel is installed, its position will not be easily moved, and the flexible air duct is usually arranged in the middle and upper part of the side wall of the t...
