Description
Technical field
The present invention relates to the equipment on a kind of ship-building gantry crane, be particularly related to a kind of multifunctional upper trolley hoisting beam of ship-building gantry crane, what this hanging beam had merged rotatable advantage of the single row of hanging pulley and general hanging beam opens crotch suspension centre size benefits more, and the movable pulley spacing of hanging beam is adjustable, it is adjustable to be that suspension centre is opened the crotch spacing, and it is wide to be suitable for the fragment size scope that hangs.
Background technology
The ship-building gantry crane upper trolley hoisting beam of prior art has two kinds, a kind of row of hanging that uses for single hook, and another kind is two hanging beams that suspension hook is used, but two kinds of hanging beams all have its limitation.
Prior art one: single hook block row is provided in a side of under each suspension hook of dolly, and this single hook block row main parts size is steel rope lockset, pulley, sheave shaft, equalizing bar, hinge, three or four pulleys is set, to hang the lifting lockset under the crossbeam.Earhole is set in the middle of the crossbeam top, and hinged with the fraising on hinge and the suspension hook, the steel rope lockset is suspended on above the pulley, and the lockset bottom is connected with weight with shackle, with hoisting heavy.
When two suspension hooks of last dolly lift body section, the longitudinal axis line parallel of two rows of hanging, and with ship-building gantry crane girder longitudinal axis line parallel, the row's of hanging lockset respectively hangs an end of body section under two suspension hooks of last dolly, realizes lifting body section.When last dolly and following dolly are united when lifting body section, because suspension hook can rotate, therefore after suspension hook drives the row's of hanging rotation 90 degree, the length direction in-line of two rows of hanging, and it is vertical with ship-building gantry crane girder length-wise axis, two rows of hanging of last dolly are an end of lockset suspension body section down, and following dolly main hook lockset hangs the other end of body section, realizes lifting body section.
Because body section length is widely different, several meters of having are long, tens meters of having are long, each suspension hook of last dolly is the configuration row of hanging separately, though solved many hitch poinies of adaptation body section problem, but because last dolly two suspension hook spacings can not change mostly, even last dolly is provided with the suspension hook transverse-moving mechanism, two suspension hook spacings change also has only two or three meter, and therefore when the body section that lifting and last primary coupler distance differ greatly, last dolly hoist rope drift angle is bigger, when lifting altitude is more and more higher, the drift angle constantly increases, and the stressed increase of steel rope, long-term use cause the rope life-span to reduce.During this external lifting small size segmentation, deflection in the hoist rope is rising when being raised to certain altitude, and raising line has the danger of grazing girder.To sum up, when two suspension hooks of last dolly are joined independently the row of hanging, though solved the rotation problem of suspension centre well, because suspension centre opens crotch and can not change, so when the subsection hull of different size lifted by crane, can bring the problem of the excessive or grazing girder in raising line drift angle.
The hanging beam that two: two suspension hooks of prior art are used is provided in a side of between two suspension hooks of dolly, promptly goes up hanging beam of configuration between two suspension hooks of dolly.This hanging beam main parts size is steel rope lockset, pulley, sheave shaft, crossbeam, hinge, and three pairs or four pairs of pulleys are set under the crossbeam, to hang the lifting lockset.The crossbeam two ends are provided with earhole, use the fraising on hinge and the suspension hook hinged respectively, and the steel rope lockset is suspended on above the pulley, and the lockset bottom is connected with weight with shackle, with hoisting heavy.The pulley axis of this hanging beam and hanging beam length-wise axis spatial vertical, and sheave shaft is fixed on above the crossbeam, and pulley can not rotate around the vertical axis.The pairing of pulley on the hanging beam is used, and can form three, four groups and open the crotch size, and is different different with hanger position in the segmentation to adapt to body section length, makes suspension strop keep vertical as far as possible, raising safety in utilization and steel rope service life.
When last dolly lifts by crane body section separately with this hanging beam, at first select to open the close a pair of pulley of crotch size, on pulley, be equipped with shackle, establish the suspension cable wire again unloading to detain with segmentation, cable wire two ends line is vertical with segmentation two ends suspension centre line, realizes the upper trolley hoisting beam hoisting heavy for such one.When last dolly and following dolly are united when lifting body section, at first select and the close a pair of pulley of one section hanger size of segmentation, on pulley, be equipped with the two-stage shackle, establish the suspension cable wire again unloading to detain, cable wire two ends line is parallel with segmentation two ends suspension centre line, realizes that dolly lifts body section up and down.
In two lifting programs of technology two, because pulley is fixed on the hanging beam, can not rotate, therefore by one-level being set or the two-stage shackle realizes spinfunction, to adapt to different lifting programs around plumb bob vertical.Promptly when last dolly is used hanging beam separately, consider stress balance and hanging position demand, every place pulley under a shackle need be set, and unite when lifting segmentation at dolly up and down, under the every place of the reason pulley two shackles need be set equally.Therefore, when different segmentations of lifting or different schemes, need parts such as dismounting lockset and shackle, in practical operation, the Current Collector Sleave that dismounting one cover 600t goes up dolly need put down suspension hook to ground, then by several alongshoreman's operations, nearly altogether one hour time, waste time and energy, inefficiency has a strong impact on production.In addition, this scheme need dispose three, four pairs of assembly pulleys, and it is more to be equipped with pulley, and every pair of assembly pulley is fixed on a position, and waste is serious.
Summary of the invention
At present mainly contain the hanging beam that the row of hanging that single hook uses and two suspension hooks are used, all just solved a certain mono-function, hang and mediate the suspension centre of having determined and to rotate problem around plumb bob vertical, do not open the variable problem of crotch but do not solve suspension centre at the ship-building gantry crane hanging beam of usefulness.And having solved suspension centre, upper trolley hoisting beam opens the variable problem of crotch, but do not solve suspension centre and can rotate problem around plumb bob vertical, and lockset such as the configure shackle that in use also need expend time in, to realize equivalent spinfunction, to open crotch variable in order to reach suspension centre simultaneously, the needs outfit is many opens the crotch size to pulley to form difference, cause serious waste for addressing the above problem, the invention provides a kind of multifunctional upper trolley hoisting beam of ship-building gantry crane, it is variable that this hanging beam has realized that not only suspension centre is opened crotch, simultaneously suspension centre place pulley can be around its plumb bob vertical rotation, and opens the movable pulley of crotch and only need a pair ofly can adjust the different crotch of opening, and need not be provided with many to assembly pulley.
