Principle of the present invention is described as follows:
Referring to Fig. 1, according to deck crane outside drawing, deck crane profile mainly comprises tower body 1, driver's cab 71, arm 20, suspension hook group, steel rope 18.SOLAS standard 5 degree sight lines require to refer to: when ship's navigation, on ship, operator's compartment is at the eye height place of code requirement, and the width of obstacle is no more than 5 degree.Eye height is generally at the middle part of tower body 1 height, because marine crane boom 20 is positioned at sight line bottom, not affected by sight line, and the width dimensions of driver's cab 71, hook assembly, steel rope 18 is all less than tower body 1, therefore, tower body 1 is the decisive factor whether deck crane meets 5 degree sight lines.Just because of this, the structure that the present invention is directed to tower body 1 designs, and the effect of chief component composition is described below:
1, bottom cylindrical structure 2, middle part conical structure 3, top cylinder structure 4:
The design middle and lower part cylindrical structure 2 is with the diameter of top cylinder structure 4 than being 1.1:1, and this diameter is than representing that bottom cylindrical structure 2 is larger than top cylinder structure 4 diameters; As larger in ratio, top cylinder structure 4 is less, and tower body inner wire rope may be interfered with top cylinder structure 4; As less in ratio, top cylinder structure 4 is suitable with bottom cylindrical structure 2 diameters, and during crane work, arm may be interfered with top cylinder structure 4.
The design middle and lower part cylindrical structure diameter is φ 2530, and top cylinder diameter of movement is φ 2300, and the supporting deck crane of domestic 57000T ship requires the maximum oad of tower body can not surpass φ 2600.Thereby the design meets the maximum oad of tower body of the supporting crane requirement of 57000T ship.
Thickness Ratio between the design middle and lower part cylindrical structure 2, middle part conical structure 3, top cylinder structure 4 is 20:16:13, its reason is: when tower body structure is stressed, stressedly from bottom to top reduce gradually, for making the stressed rear intensity of three-stage structure close, the design reduces middle part, upper steel plate thickness, makes top, middle part, bottom section intensity suitable, realizes equal strength design and cost-saving object, and tower body structure is by verification experimental verification, design safety is reliable.
The manufactured materials of the design middle and lower part cylindrical structure 2, middle part conical structure 3, top cylinder structure 4 is all AH36, guarantees the structural strength of tower body 1 by this manufactured materials of AH36, and adapts with applied environment peculiar to vessel.AH36 represents that yield strength is the high strength A level ship steel of 355MPa, and this trade mark of AH is international standard, represents specially ship steel, is the trade mark of steel for specialty.
2, Access Door tapping 5: the object of Access Door tapping 5 is to keep in repair for tower body structure internal unit, and the object of Access Door coaming plate 52, Access Door pasting board 53, interior power transmission gusset 54, outer power transmission gusset 55 is to carry out transmission and the reinforcing of power, structure to tapping is strengthened, thereby maintains the structural strength of tower body after perforate.
3, ventipane tapping 6, driver's cab tapping 7: middle part conical structure 3 is steel plate roll-forming, driver's cab tapping 7 and ventipane tapping 6 are set after moulding more thereon, the bore size of driver's cab tapping 7 is greater than the bore size of ventipane tapping 6, and arc surface is identical, therefore can utilize driver's cab open-celled structure to be attached to ventipane perforate outside, weld, so that ventipane tapping 6 is reinforced.Ventipane tapping 6 is hoisting crane cooling intallation wind exhausting outlet, and it makes to discharge under wind direction by the structure design of vertical muscle, coaming plate, and transmits the structure stress of tapping, guarantees the structural strength of tapping.
4, air-inlet window tapping 8: by vertical muscle, coaming plate, carry out transmission and the reinforcement of power, and play the effect that air intake, anti-wave enter.Air intake effect refers to: deck crane is by ventipane 61 air drafts, and in the process of air draft, the inside of tower body 1 forms negative pressure, and air is sucked to tower body structure from air-inlet window 81.The effect of entering of anti-wave refers to: deck crane is installed aboard ship, and in ship navigation, tower body structure need prevent that wave from entering, and air-inlet window tapping 8, when wave enters from air-inlet window tapping 8, prevents that by coaming plate wave from entering tower body structure upward.
