Bracket for induced draught ventilator

摘要

Bracket for induced draught ventilator, consisting of a stationary housing (4) enclosing a ventilator (1) and having an axial sucking-in pipe (2) and a tangential outlet (3), and also a drive motor for the ventilator (1), the ventilator (1) and the motor being mounted on a stand (10) tiltable with respect to the stationary housing (4) and the housing (4) being equipped with a cover (12) which covers the ventilator (1), lies with flush edges against an annular flange (11) of the housing and is held firmly against the annular flange (11) by means of a releasable clamping ring (13). The motor is mounted on a slide (17), capable of being locked in a continuously adjustable manner, on the stand (10). The stand (10) is mounted on a pivoting shaft in a base frame fixed to the ground, and the stand (10) and the base frame are provided with stops and counter stops for limiting the pivoting travel of the stand (10) on both sides. For this purpose, the base frame is formed by two jaws (23) enclosing the stand (10) on both sides and each having an undercut (22), and the stand (10) is provided with a projection (24) which engages underneath the undercut (22), the pivoting travel of the stand (10) being limited by the stop of the projection (24) on the undercut (22), on the one hand, and on the base frame, on the other hand. <IMAGE>
