Gauntry crane of the present invention has been realized general assembly gauntry crane waterborne at the barge final assembly technique, utilizes covered barge to be carrier, general assembly gauntry crane on covered barge.By the technology of the present invention, directly drop into production general assembly overall process, guarantee product efficiently, reliably, general assembly safely, realize the general assembly of complete machine factory, provide assurance for complete machine transportation and complete machine debark.
Adopt final assembly technique of the present invention, finished the overall process of large gantry crane factory general assembly, broken shipyard gauntry crane since the dawn of human civilization because of the restriction of originating firm place can only the loose mail shipping situation, solve the problem that the gauntry crane unit assembling of ship machinery is gone on board and shipping is debarked effectively, had obvious effect and profound significance.
Description of drawings
Accompanying drawing is by the scheme of installation of a kind of gauntry crane of the present invention at the barge final assembly technique.
The specific embodiment
Referring to accompanying drawing, at the barge final assembly technique, at first the pylon 2 of two settings of fixed installation on covered barge 1 makes gauntry crane stride covered barge and installs according to a kind of gauntry crane of the present invention.Because the gauntry crane span is big, covered barge length is not enough, is therefore supporting gauntry crane by two pylons 2 that are located on the barge.
Each large assemblies of gauntry crane is comprised girder 3, rigidity leg 4, flexible leg 5, cart walking mechanism and dolly assembly, finish in the assembling of the wharf apron of factory in advance.
Utilize two large-scale floating cranes with girder 3 lift synchronously with two integrally welded pylons 2 of barge on, and be connected and fixed with pylon.
Then utilize crane barge lifting in advance on ground rigidly connected flexible leg 5 fix with girder 3 contrapositions, flexible leg end girder section and girder interlude are fixed by flange and bolted connection, weld the location in casing then, finishes all weld seams.
Then utilize the crane barge lifting to fix with girder 3 contrapositions at the rigidity leg 4 that the ground welding finishes in advance again, guarantee the pre-arch deviant of supporting leg and girder, rigidity leg end girder section and girder interlude are fixed by flange and bolted connection, and all weld seams are finished in location welding in casing then.
Cart walking mechanism is installed on the supporting leg,, also cart walking mechanism separately can be installed separately according to the harbour situation.For transportation safety, lower center of gravity, the dolly assembly of gauntry crane can be placed on the girder.
Because the present invention adopts buoyancy barge general assembly scheme, just requires main beam structure one-time-reach-place when the barge assembly unit, because just can't do over again behind the rail that falls.Rigidity leg end girder section is made similar standard setting piece, simultaneously flexible leg end girder section is made similar standard setting piece, adopt the bolted form of flange face to put in place with other segmented assembly of girder in advance, install with rigidity leg, flexible leg respectively then, when making, just begin to control the deflection in each process, guarantee to install the back deflection and adhere to specification.
