Two large ropes of derrick lifting are set in the bilateral symmetry of derrick and base, meanwhile, two seat of honour big lifting ropes are set in the bilateral symmetry of derrick and base.
Double lifting derrick of the present utility model and base, be further characterized in that:
One group, pulley is formed by four pulley combinations.
Two groups, pulley is formed by two pulley combinations.
One end of the large rope of derrick lifting is fixed in the middle part of derrick on rear column otic placode, and the other end hangs over after walking around two groups, pulley and one group, pulley successively and hangs hoisting on tripod of being connected with swimming.
One end of seat of honour big lifting rope is fixed on the fixing otic placode of well man-like shelf side, and the other end hangs over after walking around pulley and one group, pulley successively and hangs hoisting on tripod of being connected with swimming.
The beneficial effects of the utility model are, this double lifting derrick and base, retain a former wire rope handling continuous lifting derrick, understructure pattern, at derrick, man-like shelf, base increases large rope and connect otic placode, leading block, two cover lifting pulley and big lifting rope is adopted to hoist respectively on derrick and base, add large rope rope coefficient amount when derrick and the seat of honour hoist, and to providing lineoutofservice signal pull to support in the middle part of derrick, jib-length during significantly to reduce derrick lifting, reduce derrick and seat of honour lifted load, improve pulley accessory structure stress, meet and significantly improve derrick operation height and safe space, carry top to drive and top drive guide rail carries out hoisting and the structural requirement of transferring.
