Abstract
The utility model relates to a lateral type tunnel fan erecting device. Longitudinal ventilation by jet fans is mostly adopted for tunnel ventilation, the fans are hung on a vault or hung on the side wall through embedded parts, installation and overhauling are complicated, and risk of falling exists. Channel steel columns in rows longitudinally are arranged between an inner tunnel contour and a limit contour line, and the bottom ends of the channel steel columns are fixed on bottom fixing steel plates of the bottom surface of a tunnel lining. A plurality of horizontal transverse I-steel cross beams are fixed on the channel steel columns from top to bottom, and the end portions of the other ends of the I-steel cross beams are fixed on lateral fixing steel plates on the lateral surface of the tunnel lining. Horizontal longitudinal I-steel cross beams are fixed between the longitudinal adjacent channel steel columns. The jet fans are fixed on the horizontal transverse I-steel cross beams, and a central axis of each jet fan is parallel to that of a tunnel. The cross section of the tunnel with the fans is expanded properly, section steel is used for producing a floor type fan foundation platform which is laterally welded with the embedded steel plates in concrete, and thus stability during operations of the fans is guaranteed.

U-steel column is fixed with the i iron crossbeam of some horizontal cross from top to bottom, and the i iron crossbeam other end end of horizontal cross is fixed on the side fixation steel plate of tunnel lining side setting;
Longitudinally between adjacent U-steel column, be fixed with the longitudinal i iron crossbeam of level;
Jet blower is fixed on the i iron crossbeam of horizontal cross between U-steel column and tunnel lining side, and its central axis is parallel with tunnel central axis.
The below at the i iron crossbeam middle part of its lowest position horizontal cross is also provided with upright U-steel column, and the bottom of this U-steel column is fixed on the bottom fixation steel plate of tunnel lining bottom setting.
The longitudinal forward and backward side of i iron crossbeam of its lowest position horizontal cross is provided with two U-steel columns, the height of the U-steel column of the height of four U-steel columns and its lowest position horizontal cross i iron crossbeam below is identical, between the adjacent U-steel column of top and vertical, horizontal, is also fixed with i iron crossbeam.
U-steel column intersects and is fixed with reinforcing angle with coffin inner opposite angle vertical, horizontal, vertical of i iron crossbeam composition.
The utlity model has following advantage:
The utility model fabrication and installation are convenient, blower fan place tunnel cross-section will be set suitably to be expanded, then adopt shaped steel to manufacture console mode blower foundation platform, pre-embedded steel slab welding in side direction and concrete, stability while ensureing blower fan operation with this, all shaped steel all does antirust processing, has the plurality of advantages such as construction is simple, maintenance is convenient, safety is firm.
