The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-4, the telescopic gantry crane of a kind of luffing folding arm, comprises left luffing folding arm telescoping mechanism, right luffing folding arm telescoping mechanism and crossbeam.Two luffing folding arm telescoping mechanisms form by base 1, principal arm 2, derricking cylinder 3, folding arm 4, folding arm cylinder 5, telescopic boom 6 and telescoping cylinder 7.Base is fixed on the deck of research vessel, one end of principal arm is connected with base by jointed shaft A8, the other end of principal arm is connected with one end of folding arm by jointed shaft B9, one end of derricking cylinder is connected with base by jointed shaft C10, the other end of derricking cylinder is connected with the position near jointed shaft B on principal arm by jointed shaft D11, one end of folding arm cylinder is connected with the position near jointed shaft A on principal arm by jointed shaft E12, the other end of folding arm cylinder is connected with folding arm by jointed shaft F13, folding arm is provided with straight cavity, telescopic boom is actively plugged in the straight cavity of folding arm, telescoping cylinder is installed in the straight cavity of folding arm, its one end is connected with one end near jointed shaft B on folding arm by jointed shaft G14, its other end is connected by jointed shaft H15 with telescopic boom.The vertical connection of front end of described crossbeam and two telescopic booms, on crossbeam 16, be at least provided with a suspension centre 161.
Above-mentioned two luffing folding arm telescoping mechanisms are considered from the angle of execution, by luffing mechanism, folding arm mechanism and telescoping mechanism, are formed.Base, principal arm and three of amplitude oil cylinder connect and compose luffing mechanism, and under the effect of hydraulic efficiency pressure system, amplitude oil cylinder action, drives principal arm clockwise or reverse certain angle around jointed shaft A, bow or backward wing before gantry crane is completed.Principal arm, folding arm and three, folding arm cylinder connect and compose folding arm mechanism, under the effect of hydraulic efficiency pressure system, and the action of folding arm cylinder, drive folding arm is clockwise or reverse certain angle around jointed shaft B, makes gantry crane complete nutation or faces upward action.Folding arm, telescopic boom and three of telescoping cylinders connect and compose telescoping mechanism, and under the effect of hydraulic efficiency pressure system, telescoping cylinder action, drives telescopic boom stretch out or retract, and drives transverse arm to move simultaneously, gantry crane are completed stretch or contract action.Above-mentioned folding arm mechanism coordinates with luffing mechanism, has expanded working space, and telescoping mechanism coordinates with folding arm mechanism, has further expanded working space.
Adopting this gantry crane to carry out operation can be referring to following workflow:
When investigating operation, gantry crane conventionally and winch 1, is used in conjunction with, and Fig. 5-8 are depicted as gantry crane and carry out the workflow of the deck side of a ship while hanging, and are specially:
The first step, make gantry crane in recovery state, then the hawser of winch by being lifted on the pulley 2 of suspension centre, after fix instrument and equipment 3,, referring to Fig. 5.
Second step, gantry crane are done folding arm action, and suspension centre raises, and the instrument and equipment of slinging, referring to Fig. 6.
The 3rd step, gantry crane are done expanding-contracting action, and suspension centre continues raise and outwards move, and instrument and equipment is gradually away from ship side, referring to Fig. 7.
The 4th step, gantry crane are done luffing action, and suspension centre reduces the while gradually away from ship side, and then gantry crane stops action, enters static mode of operation.Referring to Fig. 8.
In above-mentioned four step course of action, the distance according to the instrument and equipment of suspention apart from pulley, winch will carry out cable laying or take-up at any time, and to guarantee safety, after gantry crane remains static, winch can continue cable laying until length or the degree of depth needing.
When reclaiming, to hang workflow contrary for the workflow of gantry crane and the above-mentioned side of a ship, and in gantry crane removal process, winch carries out take-up or cable laying according to instrument and equipment apart from the distance of pulley, to guarantee safety equally.
The technical index of the telescopic gantry crane of this folding arm (oad and workload etc.) can design according to actual needs and adjust, in the situation that the action of folding arm and luffing can meet working space, Telescopic can omit when design is produced, like this can be in the situation that guaranteeing product function, cost-saving to greatest extent.
To sum up, this luffing folding arm telescopic door be hung under recovery state, have take up room little, underslung advantage, after expansion, there is wider working space, guaranteed the sling height of geological sampling instrument, owing to adopting the connection structure of left and right two luffing folding retractable mechanisms, make gantry crane there is higher stability and load-carrying capacity, met the workload of lifting needs.Wherein, luffing, folding arm and stretch under the control of corresponding hydraulic actuating cylinder, can stepless time adjustment, in the situation that sea situation is severe, with respect to straight arm type gantry crane hoisting point position, more easily controls, and applies more convenient.
