| description | The ventilation device for tunnel construction comprises a bottom plate, an exhaust fan and a ventilator are fixedly installed on the top of the bottom plate, dust filtering covers are attached to the exhaust end of the exhaust fan and the ventilation end of the ventilator, motors are arranged on the sides, away from the exhaust fan and the ventilator, of the dust filtering covers, and the motors are connected with the exhaust fan and the ventilator. An output shaft of the motor is fixedly connected with a rotating piece; through cooperation of a circular plate, a damping rod, a second spring and a rolling wheel, the device is convenient to move and can move on the uneven ground, so that the device can be moved to a construction site along with deep construction of a tunnel during tunnel construction, and when dust covers corresponding to an exhaust fan and a ventilator are covered with dust, the device can be moved to the construction site along with deep construction of the tunnel. The output shaft of the m |
