B7, traction jack power conversion contracting cylinder: traction jack (7) power conversion contracting cylinder, make rear clamper (8) stress clamp chain
Bar；
B8, fore-clamp holder are opened: front clamp very heavy synthlipsis cylinder makes fore-clamp holder (5) open to loosen chain；
Cylinder stretched by b9, traction jack: cylinder backhaul is stretched in traction jack (7)；
B10, traction jack are stretched cylinder and are put in place: jack to be drawn (7) is stretched cylinder and put in place, repeat above b2 ~ b10 step action and realize
Transferring continuously of weight.
A kind of chain type tractive device for raising of a wreck the most according to claim 3 realizes the traction construction of raising of a wreck
Method, it is characterised in that: this construction method also includes a compensation of undulation program, cannot move at chain before promoting operation and starting
By gripper position after compensating jack regulation to being suitable for clamping chain in the case of Dong；Secondly, when the water surface (14) has wave
Time, at accumulator or with under electric-control system synergy, it is passively or actively top after stretch/shrink cylinder drives by compensating jack (10)
Push away beam (9) to seesaw, finally drive chain (3) to seesaw, offset, with this, the barge caused due to the water surface (14) wave
(12) heave movement impact on chain (3) stretching force so that chain (3) stretching force keeps steady statue.
