Description
Technical field
The present invention relates to the mechanical equipment field, in particular to the reassembling type wharf crane.
Background technology
The coastal dock loop wheel machine is influenced greatly by the marine corrosive climate environment, and wharf crane must be done corrosion protection design, if the hard-wired loop wheel machine of harbour, it receives seashore corrosion weather effect throughout the year, and etching problem is even more serious.If loop wheel machine is moved storehouse storage to after but obsolete time at high speed is disassembled, can Fast Installation during application, then can prolong greatly its service life.
And under " three height " harsh environment the reassembling type wharf crane is set by the sea; Existence is than multi-constraint condition: the material antiseptic performance requriements is high, and each single parts will satisfy manpower transport's weight limits, do not have on the harbour want under the auxiliary erecting equipment condition can Fast Installation with disassemble; The storehouse parking space is to constraint of the volume shape of each parts etc.; Design overall wants cube little, and is in light weight, and parts are few.And above-mentioned requirements is contradictory in manufacturing and designing enforcement, and is lower like the rigidity of common corrosion-resistant steel, takes into account various designing requirements and has cooresponding difficulty.
Therefore, need a kind of new reassembling type wharf crane, at withstanding corrosion simultaneously, also have enough intensity, and volume is little, in light weight, parts are few, can realize not having under the accessory equipment situation fast speed and install and disassemble.
Summary of the invention
For addressing the above problem, need a kind of new reassembling type wharf crane, at withstanding corrosion simultaneously, also have enough intensity, and volume is little, in light weight, parts are few, can realize not having under the accessory equipment situation fast speed and install and disassemble.
In view of this, the invention provides a kind of reassembling type wharf crane, comprise chassis, base, swivel and arm, wherein, said chassis is fixed on first ground of harbour, and said chassis comprises disk body and a plurality of and said disk body bonded assembly first attaching parts; Said base comprises intermediate sleeve, first supporting component, second supporting component and bearing set; Said bearing set is arranged in the said intermediate sleeve; Said intermediate sleeve is positioned at the middle position of said first supporting component; Captive joint through a crossbeam between said first supporting component and said second supporting component; Said first supporting component, said second supporting component and said crossbeam constitute the I-shaped structure, through being connected of a plurality of second attaching partss and said a plurality of first attaching partss said first supporting component and said second supporting component and said chassis being fixed together; Said swivel comprises S.
