Abstract
The invention discloses a marine knuckle boom crane, belongs to the technical field of shipbuilding, and the crane comprises a base, a stand column and a telescopic boom, wherein the telescopic boom is controlled through a first oil cylinder; a hoist engine is arranged at the lower end of the telescopic boom; the extension end of the telescopic boom is provided with a metal shell used for enclosing a electromagnet; a toggle switch electrically connected with the electromagnet is arranged on the metal shell; the switch bar of the toggle switch stretches out of the metal shell, and a switch oil cylinder is connected between the outside of the boom body of the telescopic boom and the switch bar; an inner arm, which is controlled to be folded through a third oil cylinder, is hinged between the top end of the stand column and the telescopic boom; a second oil cylinder, which is used for folding the telescopic boom, is arranged on the inner arm; the two ends of the second oil cylinder are respectively hinged to the two ends of the inner arm, and the bottom end of the stand column is connected with the base through a slewing bearing. By adopting the marine knuckle boom crane, the problem that a current marine crane cannot load and unload small messy ferrous metal objects, can only perform one-way operation, cannot be folded so as to influence the speed of a ship can be solved.
Description
Technical field
The present invention relates to shipbuilding technical field, especially a kind of folding arm loop wheel machine peculiar to vessel.
Background technology
Loop wheel machine peculiar to vessel, the machinery lifting by crane for the goods of seat transport ship, load and unload, a kind of loop wheel machine peculiar to vessel, include the base be welded on ship deck pedestal and the column be fixed on base, the top of column is hinged with the telescoping boom controlled by oil cylinder, telescoping boom lower end is provided with hoister winch, and oil cylinder is connected with the pumping plant installed above deck by pipeline, and Electric Machine at Pumping Station is electrically connected with loop wheel machine controller; This machinery also exists following problem: a, its can only to one integral piece, be contained in pallet or the goods be contained in packing chest and load and unload, then cannot load and unload for the scrap iron at random of smallclothes or the ferrous metal goods of pallet-free; B, due to base and column be fixedly connected with and pumping plant install above deck, and arm can not draw in, telescoping boom can only be the unidirectional operation of stretching out forward and retracting, therefore it not only uses inconvenience, affect work efficiency, also take up room large, wind area is large, affects the moving velocity of hull.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of folding arm loop wheel machine peculiar to vessel, and this folding arm loop wheel machine peculiar to vessel can solve existing ship loop wheel machine can not load and unload the ferrous metal goods at random of smallclothes and it can only unidirectional operation and folding can not affect the problem of hull moving velocity.
In order to solve the problem, the technical solution adopted in the present invention is: this folding arm loop wheel machine peculiar to vessel, the telescoping boom including base, column and controlled by the first oil cylinder, described telescoping boom lower end is provided with hoister winch, described telescoping boom external part is provided with the metal shell of going along with sb. to guard him electromagnet, described metal shell is provided with the toggle switch be electrically connected with described electromagnet, the shifter bar of described toggle switch stretches out described metal case, is connected with switch oil cylinder outside the wall body of described telescoping boom and between described shifter bar; The inner arm being controlled folding by the 3rd oil cylinder is hinged with between described column top and telescoping boom, described inner arm is provided with the second oil cylinder for telescoping boom described in folding, the two ends of described second oil cylinder are articulated with the two ends of described inner arm respectively, and described column bottom is connected with described base by single-revolution supporting.
In technique scheme, technical scheme can also be more specifically: described telescoping boom is sleeve type telescopic boom.
Further: described inner arm two ends are respectively arranged with the first connecting panel and the second connecting panel, described first connecting panel is hinged with the top of described column, the external part of described 3rd oil cylinder and the fixed end of described second oil cylinder respectively; The fixed end of described second connecting panel and described telescoping boom is hinged, and described second connecting panel is hinged by the external part of a pipe link and described second oil cylinder; The described fixed end of the 3rd oil cylinder and the lower end of described column are hinged.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, because telescoping boom lower end is provided with hoister winch, and its external part is provided with electromagnet, can lift event goods or handling smallclothes, ferrous metal goods at random, pallet-free as required, can meet the handling needs of different goods.Simplicity of design is reasonable, convenient and practical.
2, owing to being hinged with the inner arm by the 3rd oil cylinder folding between the top and telescoping boom of column, at second oil cylinder of the two ends, below of inner arm difference hinged for folding telescoping boom, make the working suspension arm of loop wheel machine can fold gathering when not working, the compact overall structure of loop wheel machine, do not take between deck space, wind area is little, does not affect the moving velocity of ship.
