Description
Technical field
The present invention relates to mechanical equipment field, in particular to dismounting wharf crane.
Background technology
Coastal dock loop wheel machine is subject to marine corrosive Climatic Effects large, and wharf crane must be done corrosion protection design, if the hard-wired loop wheel machine of harbour, it is subject to seashore corrosion weather effect throughout the year, and etching problem is even more serious.If loop wheel machine be moved storehouse storage to after the obsolete time can rapid disassembling, can Fast Installation during application, can greatly extend its service life.
And under " three height " harsh environment, dismounting wharf crane is set by the sea, existence is compared with multi-constraint condition: material antiseptic performance requriements is high, each single parts will meet manpower transport's weight limits, on harbour without under auxiliary installing device condition, want can Fast Installation with disassemble, storehouse parking space is to constraint of the volume shape of each parts etc., design overall wants cube little, lightweight, and parts are few.And above-mentioned requirements is contradictory in manufacturing and designing enforcement, as lower in the rigidity of common corrosion-resistant steel, take into account various designing requirements and there is suitable difficulty.
Therefore, need a kind of new dismounting wharf crane, at withstanding corrosion simultaneously, also have enough intensity, and volume is little, lightweight, parts are few, can realize without fast speed in accessory equipment situation and install and disassemble.
Summary of the invention
For addressing the above problem, need a kind of new dismounting wharf crane, at withstanding corrosion simultaneously, also have enough intensity, and volume is little, lightweight, parts are few, can realize without fast speed in accessory equipment situation and install and disassemble.
In view of this, the invention provides a kind of dismounting wharf crane, comprise chassis, base, swivel and arm, wherein, described chassis is fixed on the first ground of harbour, and described chassis comprises disk body and the first attaching parts a plurality of and that described disk body is connected, described base comprises intermediate sleeve, the first supporting component, the second supporting component and bearing set, described bearing set is arranged in described intermediate sleeve, described intermediate sleeve is positioned at the middle position of described the first supporting component, between described the first supporting component and described the second supporting component, by a crossbeam, be fixedly connected with, described the first supporting component, described the second supporting component and described crossbeam form I-shaped structure, by being connected of a plurality of the second attaching partss and described a plurality of the first attaching partss described the first supporting component and described the second supporting component and described chassis being fixed together, described swivel comprises S.
