Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Upper and lower, left and right in below describing are as the criterion with diagram, and actual conditions by that analogy.
Prior art is when being fixed on multi-stage oil cylinder 10 on derrick 11, the mode adopted is: the bearing pin 8 removing base 12 and multi-stage oil cylinder 10 cylinder head, then with crane lifting multi-stage oil cylinder 10, simultaneously by self hydraulic system of multi-stage oil cylinder 10 and crane synchronous matching, the piston rod of multi-stage oil cylinder 10 is allowed to regain, then multi-position action personnel climb on derrick 11, bearing pin 8 could be in place.
With reference to Fig. 1, Fig. 3, Fig. 4, structure of the present utility model is,
Be included in predetermined installation site, derrick 11 same side and be welded with otic placode A1, otic placode D13 and otic placode C3 respectively, otic placode D13 is below otic placode A1, otic placode C3 is positioned at below otic placode D13, the length that the distance of otic placode C3 and otic placode D13 and multi-stage oil cylinder 10 are retracted at the is end suitable, base 12 is welded with otic placode E14 and otic placode B2, otic placode B2 is (the inside and outside differentiation of Fig. 1) outside base 12, and otic placode E14 is positioned at the inner side of otic placode B2; Otic placode D13 and multi-stage oil cylinder 10 piston rod end hinged, multi-stage oil cylinder 10 cylinder head end, by bearing pin 8 and otic placode E14 grafting, multi-stage oil cylinder 10 cylinder head end urceolus is provided with pulley 4; Drawn one end of guide steel wire rope 5 by shackle 9 from otic placode A1, guide steel wire rope 5 other end, through after pulley 4, is connected with otic placode B2 by wire clips thimble 6, flower basket bolt 7 successively.
Fig. 2, otic placode C3 are provided with a downward-sloping groove, and the opening's edge of groove bends.
The course of work of the utility model device is,
With reference to Fig. 1, first utilize multi-stage oil cylinder 10 derrick telescoping 11;
With reference to Fig. 3, the connection removing multi-stage oil cylinder 10 and base 12 is needed before the base 12 that hoists, namely the bearing pin 8 that base 12 is hinged with multi-stage oil cylinder 12 is removed, then this bearing pin 8 is arranged on the lug of multi-stage oil cylinder 10 cylinder body lower end, all regained by the piston rods at different levels of self HYDRAULIC CONTROL SYSTEM multi-stage oil cylinder 10, in withdrawal process, slided along guide steel wire rope 5 to top contraction edge by pulley 4 in multi-stage oil cylinder 10 cylinder body lower end again.When multi-stage oil cylinder 10 piston rod at different levels is regained completely, loosening flower basket bolt 7 makes multi-stage oil cylinder 10 cylinder body lower end rely on gravity and derrick 11 to press close to, stop when multi-stage oil cylinder 10 bottom bearing pin 8 aligns directly over otic placode C3 groove, now operating hydraulic system makes the piston rod of multi-stage oil cylinder 10 suitably stretch out downwards, multi-stage oil cylinder 10 bottom bearing pin 8 is put in place along acclive otic placode C3 groove Auto-mounting, finally fixed.Regain at multi-stage oil cylinder 10 piston rod and be fixed on derrick 11, finally recurrence rises base 12.
When the lowering operation of derrick 11, adopt above-mentioned contrary mode of operation, multi-stage oil cylinder 10 is glided along guide steel wire rope 5, then connect the bearing pin 8 between multi-stage oil cylinder 10 and base 12 at low level.
With reference to Fig. 4, during rig work, multi-stage oil cylinder 10 is fixed, guide steel wire rope 5 of dismantling.
