Apparatus for maintaining tension of air supply hose of sand transfer skipper of sand file construction equipment

摘要

The present invention prevents the air supply hose attached to the skipper for supplying sand of the sand pile construction equipment from being twisted or severely shaken when the skipper moves up and down, and prevents the damage caused by the protruding part of the sand pile construction equipment. To provide a tension retaining device for an air supply hose.;The tension retaining device of the air supply hose of the sand transfer skipper of the sand pile construction equipment according to the present invention is installed in the air supply hose, the air supply hose roller to enable the length adjustment of the air supply hose in accordance with the transfer of the sand transfer skipper ; A balance weight connected by the air supply hose roller and the ring member to apply a constant tension to the air supply hose; A balance weight feed roller installed at the balance weight to smoothly move the balance weight up and down; And installed on the leader of the sand pile construction equipment, and comprises a guide channel for guiding the vertical conveyance of the balance weight feed roller.;According to the present invention, the air supply hose is suspended due to the balance additional air supply hose, and the balance addition is also moved up and down along the guide channel, so that the skipper for sand transfer in the construction equipment during sand pile construction The air supply hose supplying high pressure air to the pipe can be prevented from being twisted by wind or vibration during construction or caught by the protruding part of the sand pile equipment.
