Further, the described mechanism that produces comprises bracket, rotating hanger and auxiliary rotating hanger, described rotating hanger and auxiliary rotating hanger are arranged at respectively the two ends, left and right of homonymy ship side, rotating hanger pivoted arm head is hinged through suspender and bracket head, auxiliary rotating hanger pivoted arm is provided with capstan winch, and described capstan winch is hinged through suspender and bracket afterbody.
Further, described derricking gear comprises Π type suspension bracket and winch, described Π type suspension bracket is arranged at suspension bracket right side, Π type suspension bracket bottom is hinged along ship side direction and ship side deck, the head of Π type suspension bracket is provided with pulley, described winch is arranged on the hull at Π type suspension bracket rear, and the hawser being wire-wrapped on winch is connected with the head of carrying of gravity core pipe through pulley.
Further, on described rotating hanger and auxiliary rotating hanger, be respectively equipped with the hydraulically extensible oil cylinder that drives rotating hanger pivoted arm and auxiliary rotating hanger pivoted arm to rotate, between described Π type suspension bracket and hull, be provided with hydraulically extensible oil cylinder.
Further, the upper end face of described bracket is opening setting.
Again further, the afterbody of described bracket is connected with hull through bracket fastener.
Take after above technical scheme, beneficial effect of the present invention is:
1. adopt the bracket of end face opening to hold up elongated gravity core pipe, the bending of avoiding body to cause in human factor when hull produces or proceed to.
2. the head of bracket synchronously recalls ship side through rotating hanger and auxiliary rotating hanger, the capstan winch of the auxiliary rotating hanger of bracket afterbody discharges cable, bracket under Action of Gravity Field being vertically suspended in water, guarantee the vertical undershoot of gravity core pipe in bracket, thereby the accuracy that ensures sampling, prevents damage and distortion that gravity core pipe produces because of oblique impact.
3. after Π type suspension bracket send bracket upper surface open place to depart from bracket gravity core device by rotation, undershoot samples, after having sampled winch, mention gravity core device, the revolution of Π type suspension bracket is hung back gravity core device in bracket, has avoided body to sustain damage in lifting process.
