Description

Multifunction hoisting pole

The utility model relates to multi-functional gin pole, more clearly say so be used for lifting, grab mud, the multi-functional gin pole of auxiliary vessel such as ramming, piling or miscellaneous equipment, occasion.

The multi-functional gin pole in past has only lifting mostly, grabs mud, a kind of in the ramming, piling function, and only many can having concurrently grabbed mud, two kinds of functions of ramming.Therefore, the auxiliary vessel that the barre of difference in functionality is installed just has crane ship, dredger, pile-driving barge not.In the construction of harbour, generally at first need to grab mud or piling, be jackstone then, be ramming once more, lift square at last, have certain technology continuity.Like this, just need the operation of dredger, pile-driving barge, barge, crane ship successively.Each auxiliary vessel all will be from the towage of female port, towage and going again after construction finishes.Therefore, need a lot of manpowers of spend and decantation takes, wage and enterprise management expense, bunkerage etc., therefore construction period also elongates, and the degree of utilization of auxiliary vessel is not high yet.

The purpose of this utility model, be to overcome above-mentioned shortcoming, provide a kind of and have lifting concurrently, grab mud, the multi-functional gin pole of multiple function such as ramming, piling, thereby can build or reequip out have lifting concurrently, grab mud, can the saving human and material resources, financial resources, time greatly and improve the multifunctional engineering ship of boats and ships degree of utilization of multiple function such as ramming, piling.

In order to achieve the above object, the steel rope that is connected by an end and deck pivotally attached barre, with the barre other end of the multi-functional gin pole of the utility model, the winch that is fixed on rear end, the deck Wound steel rope other end are constituted.The crossbeam that has track is installed on the barre, crossbeam be provided with can orbital motion two coasters, two coasters by steel rope and the fixed pulley at crossbeam two ends, grab bucket traversing motor, grab bucket or hammer ram, with the hoisting drum of fixing main driven by motor above deck with open and close reel and link to each other, main motor has driven and has reused winch, grabbed hoisting drum and the switching reel that mud is used simultaneously by change-speed box and gear cluster.

The traversing of grab bucket is to realize like this.Consult accompanying drawing 2.Two coasters 5 and 6 can move along the track of crossbeam 4.Traversing motor 9 Wound steel ropes 7 of grabbing bucket, an end of steel rope 7 is fixed on the coaster 5, and is fixing through fixed pulley 20 backs on crossbeam 4 end fixed pulleys 8, the traversing motor 9 of grab bucket, crossbeam other end fixed pulley 8, the coaster 6.One end of steel rope 17 and coaster 5 are fixing, and fixed pulley 21 backs of passing coaster 6 are fixing.So, when the traversing motor 9 of grabbing bucket rotates, just drive two coasters 5 and 6 traversing, and the speed of coaster 5 is twices of coaster 6 along the track of crossbeam 4, but also relative motion each other.Hanging on the fixed pulley 22 of coaster 5 and grabbing bucket 10, grab bucket 10 just also can realize traversing.

The lifting of grab bucket and switching are to realize like this.Hoisting drum 11 and open and close reel 12 Wound steel ropes 18,19 respectively, steel rope 18,19 is walked around the fixed pulley 23 of pulley 24, coaster 6, the fixed pulley 22 of coaster 5 successively, respectively with the opening bucket, close the mechanism that struggles against and link to each other of grab bucket 10.When coiling hoisting drum 11, switching reel 12, just liftable, switching grab bucket.Grab bucket 10 when traversing, the speed of coaster 6 is 1/2nd of coasters 5, and therefore, though the distance between two coasters is increasing, length of steel wire rope is also corresponding between them is compensated, thereby 10 vertical dimensions that can keep grabbing bucket are constant.Change grab bucket into hammer ram, but just ramming.

Crossbeam can be made of for three sections left, center, right, links with mechanism easy to assemble or fold mechanism or telescoping mechanism between them.Crossbeam also can be made into one, during without crossbeam, crossbeam one end can be fallen on the deck.The reinforced rib that intensity is enough is exactly a kind of mechanism easy to assemble with the mechanism of bolted between two sections crossbeams.If do not need the function of driving piles, crossbeam can be fixed on the barre.Use these several mechanisms can arbitrarily in time shorten the total length of crossbeam, be convenient to boats and ships navigation and landing pier smoothly.Long crossbeam is convenient to again grab bucket mud is unloaded to the hopper of engineering shipboard.

Crossbeam can be fixed on the barre, also can be connected with pulley with barre.Track on the crossbeam can be designed to drive hammer and grab the jigger common type that the mud ramming is used.Such crossbeam middle part can be slide hinged with easy-to-dismount mechanism with barre, beam-end then have can with the free bearing pivotally attached hole that is fixed on the deck front end.This crossbeam is after pulling down on the barre, and the free bearing on end and the deck is hinged, and middle part and barre are slide hinged, just becomes the pile frame that can drive piles.By regulate barre lean forward or after raise, the horizontal sextant angle of pile frame also changes thereupon, thereby can play the stake of bowing, straight stake, faces upward stake, to adapt to the different requirements of construction.

The lifting function of barre is not as in the past given unnecessary details.

Task of the present utility model comes to this and finishes.

The multi-functional gin pole of the utility model has lifting concurrently, grabs mud, ramming, the multiple function of piling, can be crane ship, dredge, auxiliary vessels such as compacting hammer barge, pile-driving barge hold and are one, build or transform as multifunctional engineering ship.This has just saved human and material resources, financial resources, time greatly, has improved the degree of utilization of boats and ships.Wherein grab expense of mud function and only be equivalent to build 8～10% of a dredger with obsolete vessel repacking increase.The decantation expense of towage auxiliary vessel has then saved 50～70%.Can save the depressed place and repair expense about 50～70%.On the auxiliary vessel of engineerings such as the utility model can be widely used in building the port, repaiies harbour, dredging river, also can be applicable in miscellaneous equipment and the occasion.

Below in conjunction with drawings and Examples the multi-functional gin pole of the utility model is done further explanation.Fig. 1 is the general illustration of the utility model embodiment.Among the figure, barre 1, steel rope 2, windlass 3, crossbeam 4, grab bucket 10 etc. constitute the utility model.Long and short dash line is represented is that crossbeam 4 is pulled down situation when being adapted as pile frame 25.Fig. 2 is grab bucket or hammer ram is traversing and the scheme drawing during dipping and heaving.The traversing motor 9 of grab bucket, steel rope 7 and 17, fixed pulley 8 make the coaster 5 and 6 that is installed on the crossbeam 4 traversing among the figure, and grab bucket or hammer ram 10 are traversing thereupon.Fixed pulley 22 and 23, hoisting drum 11, open and close reel 12, steel rope 18 and 19, pulley 24 and make grab bucket 10 liftings or switching, precedingly describe in detail.The transmission of hoisting drum 11 and switching reel 12 is then shown in Figure 3 by the transmission scheme drawing.Main motor 13 reaches change speed gear box 14 with power among the figure, power is reached gear cluster 15 after slowing down again, and gear cluster 15 reaches power winch 16 at last with lifting, reaches hoisting drum 11 and opens and closes reel 12 with lifting grab bucket or hammer ram, switching grab bucket.Fig. 4 is the scheme drawing of the three sections crossbeams in left, center, right, with mechanism easy to assemble 26 connections, be beneficial to navigation to reduce the beam.

During piling, power is then provided by internal combustion stake machine in addition.

Save decantation expense 60% when the utility model embodiment constructs more in the past, collect lifting, dredge, ramming, all functions of piling be in a ship, makes the harbour works cost reduce by 4～8%.Can be widely used on the auxiliary vessel.
