The specific embodiment
Specifically introduce a preferred embodiment of the present utility model below in conjunction with accompanying drawing 1～8.
Referring to Fig. 1, the utility model is a kind of jib sliding system of heavy floating crane, and it is installed on the crane barge ship 2.This jib sliding system is made up of 1, one jib free bearing of a jib 4,9, one auxiliary barges 3 of 5, one anchor winches of 6, one sliding rails of flange bearing traction system and some luffing steel ropes 7.Auxiliary barge 3 is provided with jib bearing 8, and this jib bearing 8 connects jib 1 by ball pivot 10, is used for compensating auxiliary barge 3 bevelled positional errors.Auxiliary barge 3 guarantees that by auxiliary tugboat or winch control auxiliary barge 3 positions are always along crane barge ship longitudinal axis.Auxiliary barge 3 drives by jib 1.Referring to Fig. 7,8,, drive jib 1 and slide to the anchor station from control position by the pitching steel rope on the crane barge ship; By 2 anchor winch 91 on the crane barge ship, drive jib 1 and slide to control position from the anchor station.
Sliding rail 5 is arranged on the axis of crane barge ship 2 along the length direction of crane barge ship 2.Flange bearing 6 is installed on the sliding rail 5 and near the position of crane barge ship 2 fores, and flange bearing 6 is with 1: 50 slope, when jib 1 slides onto the flange position, jib free bearing 4 progressively raise and break away from the middle of sliding rail 5, carrying surface is changed naturally.
Referring to Fig. 2～6, jib free bearing 4 is connected to by flange bearing 6 on the hull structure of crane barge ship 2, and a seat board is established along total length in jib free bearing 4 middle parts, and slippage dolly 42 is placed in a seat board below, drives jib free bearing 4 and slides along sliding rail 5 directions.The horizontal guide wheel 43 of both sides is a flange arrangement, is installed in the both sides of jib free bearing 4, the lateral loading of jib free bearing 4 when being used for bearing slippage.Load when a middle part seat board bears slippage by slippage dolly 42.The two ends of propping up the seat board bottom are provided with vertical block 44 respectively, prevent that slippage dolly 42 breaks away from jib free bearings 4.Between sliding machine 42 and jib free bearing 4 bottoms flexible cushion block 41 is set, to reduce in the sliding process vibrations to jib free bearing 4 and jib 1.
Shown in Fig. 7,8, anchor winch traction system is made up of two anchor winches 91, two fairleads 94, two traction movable pulleys 96 and the total root 97 of two steel ropes.Anchor winch 91 is installed on the crane barge ship 2, and two fairleads 94 are installed in the section portion of crane barge ship 2 respectively, and two traction movable pulleys 96 are installed in the end of jib free bearing 4 respectively.Windlass steel rope one end connects anchor winch 91, twines fairlead 94 and traction movable pulley 96 successively, and the other end of this windlass steel rope connects the total root 97 of steel rope.
On the steel rope between traction movable pulley 96 and the fairlead 94 and twine leading sheave 92 and leading sheave 95 respectively on the steel rope between fairlead 94 and the anchor winch 91, twine a dynamometry pulley 93 on the steel rope between fairlead 94 and the anchor winch 91 respectively.
During native system work, an end of jib 1 is placed in by jib free bearing 4 on the flange bearing 6 of crane barge ship 3, and jib 1 other end is placed on the auxiliary barge 3 by jib bearing 8.Jib bearing 8 firmly is placed on the auxiliary barge 3 by supplemental support, topples preventing.
When jib 1 backward during slippage, by tightening up luffing steel rope 7, pulling jib 1 moves to midbody, and this moment, jib free bearing 4 and jib bearing 8 related auxiliary barges 3 moved with jib 1 together.During initial position, jib free bearing 4 is positioned on the flange bearing 6 of crane barge ship 3, and jib free bearing 4 slides onto on the sliding rail 5 of crane barge ship 3 gradually then.In the process that jib 1 moves, anchor winch traction system 9 keeps certain tensile force, prevents that jib 1 too fast moving from causing slipping out of control.
When jib 1 forward during slippage, loosen luffing steel rope 7 to reduce the sliding resistance of jib 1.Drive anchor winch traction system 9, make jib 1 slippage forward, this moment, jib free bearing 4 and jib bearing 8 related auxiliary barges 3 moved with jib 1 together.Forward in the process of slippage, luffing steel rope 7 must keep relaxed states, to reduce sliding resistance at jib 1.
The utility model can make jib work hinge be positioned at different hull positions by the slippage of jib, requires and hull drinking water requirement to satisfy different crane arm swinging radiuss.And during jib slippage of the present utility model, the jib hinge is positioned at midbody, and after jib fell, the front portion can be supported by the auxiliary stand of fore, shorten the jib jib-length widely.Jib can increase the ability of the transverse load that its anti-hull rolling produces by 2 supports, makes hoisting crane adapt to ocean freight.Evaded the risk that great framing member may occur in the moving process on the water effectively.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim conversion, the modification of the foregoing description.
