Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the invention will be further described, but should not limit the scope of the invention with this.
With reference to Fig. 1, in the reversing chassis water of the present embodiment, the schematic flow sheet of turn-over method, comprises the steps:
Step S11, described reversing chassis includes relative upper bottom surface and bottom surface and relative water inlet side and promotes side, water inlet side described in crane hanging component and promote side suspension centre, described reversing chassis is sling, under original state of slinging described bottom surface upward, upper bottom surface down；
Step S12, described reversing chassis is moved in water by described crane；
Step S13, breaks off relations the suspension centre of described water inlet side, makes the water inlet side of described reversing chassis enter water；
Step S14, described in described crane tractive promote side, make described reversing chassis around described lifting side suspension centre revolution stand up 180 degree, make described bottom surface down, upper bottom surface upward；
Step S15, described crane lifts the suspension centre of described water inlet side again, and is moved on bottom surface by described reversing chassis.
Referring to figs. 2 and 3, as a nonrestrictive example, reversing chassis includes: side girder 1, back end beam 2, front beam 3, center crossbeam 4, front center stringer 5, rear center's longeron 6, rear roller beam 7, front wheel amount 8, side wheel beam 9, front support rail beam 10, consequence beam-and-rail 11, front slew gear support 12, rear slew gear support 13.
In an instantiation, the whole structure of reversing chassis weighs 1700 tons, and the long * width * of overall dimensions is high, for 43*36*7.84 rice.Due to limited conditions, the available crane barge that maximum crane gear is 2200T, it includes 4, front and back suspension hook (more specifically, be 4 main hooks), and single hook maximum weighted is 550T.By each process of the state of standing up and the parameters of crane gear are analyzed, it is determined that design 4 suspension centres on reversing chassis, lift with 4 groups of steel wire ropes, i.e. 2 suspension centres of each suspension hook lifting.Wherein, 2 suspension centres are distributed in water inlet side, and other 2 suspension centres are distributed in lifting side.Wherein 2 suspension centres of 2 suspension hook lifting water inlet sides, other 2 suspension hooks lifting promotes 2 suspension centres of side.
In the process of standing up, the water inlet side of reversing chassis partly or completely reversing chassis is positioned under water, relies on the lifting pulling force of crane itself, and utilizes buoyancy of water to realize standing up of reversing chassis.Wherein, according to Archimedes' principle, buoyancy F floats=ρ water * V thing * g, and wherein V thing represents that reversing chassis is positioned at the volume of part under water.
The each body beam height of reversing chassis differs, first the volume of each casing can be calculated, further according to the depth of water situation standing up waters, guarantee that total stress F of crane hook is within the scope of safe stand under load, assume reversing chassis constitution water stands up underwater penetration during different conditions, and ensure that F+F floats > G, wherein G is the deadweight of reversing chassis.As under the underwater penetration assumed, buoyancy is unsatisfactory for requirement, it is contemplated that blow-by casing in reversing chassis structure is sealed, to strengthen the volume of underwater portion thus increasing buoyancy, it is ensured that the buoyancy that the upper loading limit of each suspension hook is subject to plus underwater portion is be more than or equal to the deadweight of reversing chassis.Secondly still it is unsatisfactory in situation at increase volume, can change and stand up waters, to ensure having enough degree of depth.
In the present embodiment, the whole process of standing up can include following state: stand up front translation → enter level put → change suspension centre promote → promote vertical → tilt to stand up → stand up the ground that puts in place → move to.It is described in detail below with reference to Fig. 4 to Figure 12.
With reference first to Fig. 4 and Fig. 5, wherein Fig. 5 is the Fig. 4 side view along D direction.Being respectively provided with suspension centre in the lifting side of reversing chassis 23 and water inlet side, the suspension hook 21 of crane lifts each suspension centre via hoisting rig.Continuing to above example, 4 suspension hooks lift the suspension centre promoting side and water inlet side respectively, are sling by reversing chassis 23 from the installation on ground moulding bed 24 being arranged on bunding 25, and under original state, upward, upper bottom surface B is down for the bottom surface A of reversing chassis 23.After reversing chassis 23 is sling, it is possible to it is translated to the direction in waters 26.
In this condition, the stress of reversing chassis 23 is as follows: F1+F2+F3+F4=G, and wherein F1, F2, F3 and F4 represent the stress of 4 suspension hooks respectively, and G represents the deadweight of reversing chassis 23.
Afterwards with reference to Fig. 6, reversing chassis 23 is being moved in water.
Afterwards with reference to Fig. 7, being broken off relations by the suspension centre of water inlet side, and have 27 at water inlet side installation side drag-line, first reversing chassis 23 is the state that level is put in water.In this condition, F1+F2+F floats=G, and wherein F floats as reversing chassis 23 buoyancy that part is suffered under water.
Afterwards with reference to Fig. 8, crane tractive promotes the suspension centre of side so that whole reversing chassis 23 tilts.In this case, F1+F2+F floats=G, and wherein F floats as reversing chassis 23 buoyancy that part is suffered under water.
Afterwards with reference to Fig. 9, crane continues tractive and promotes the suspension centre of side, and whole reversing chassis 23 returns back to plumbness around the suspension centre promoting side.In this case, F1+F2+F floats=G, and wherein F floats as reversing chassis 23 buoyancy that part is suffered under water.
Afterwards with reference to Figure 10, crane continues tractive and promotes the suspension centre of side, and whole reversing chassis 23 tilts to stand up.In this case, F1+F2+F floats=G, and wherein F floats as reversing chassis 23 buoyancy that part is suffered under water.Wherein, layback rigging 27 can act on when plumbness is to rollover conversion, to solve the resistance of water, wind etc., realizes smoothly standing up.
Afterwards with reference to Figure 11, after standing up, crane lifts the suspension centre of water inlet side again, and after keeping standing up, upper bottom surface B is upwards, and bottom surface A is downward.Standing up after putting in place, F1+F2+F3+F4+F floats=G.
Afterwards with reference to Figure 12, reversing chassis 23 is moved on ground by crane.In this case, F1+F2+F3+F4=G.Afterwards, it is possible to reversing chassis 23 is reapposed on installation on ground moulding bed 24.
Although the present invention is with preferred embodiment openly as above; but it is not for limiting the present invention; any those skilled in the art are without departing from the spirit and scope of the present invention; can making possible variation and amendment, therefore protection scope of the present invention should be as the criterion with the scope that the claims in the present invention define.
