Description
Technical field
The present invention relates to a kind of hydraulic suction dredge (suction dredger); Comprise: adopt the mud pipe; The said mud Guan Yiduan that adopts is connected to dust collecter; And the other end is connected to the hydraulic suction dredge hull through hinge connector, and said hinge connector has pivot axis, and said pivot axis is with respect to said hull level and transversal orientation; And suspension arrangement, through said suspension arrangement, the said mud pipe of adopting can move adopting between the mud position of the stop position of approximate horizontal and inclination, saidly adopts that the mud pipe comprises framework and by the plumbing installation of said frame supported.
Background technology
Such hydraulic suction dredge is open in GB-A-657.289.The mud pipe of adopting of said prior art hydraulic suction dredge comprises a plurality of parts, and said a plurality of parts provide concrete length.Depend on the length of adopting the mud pipe, consider the maximum inclination of adopting the mud pipe, concrete adopt the mud degree of depth and can obtain.Consider that the mud pipe of adopting that is in resting position must be along the supported situation of hull, it preferably should not stretch out with respect to the stern (stern) or the fore (bow) of hydraulic suction dredge hull.Therefore therefore, adopt the maximum length of mud pipe, and adopt the maximum that the mud pipe can obtain through this and adopt the mud degree of depth, be restricted.
Summary of the invention
The hydraulic suction dredge that the purpose of this invention is to provide a kind of the above-mentioned type, it allows the relatively long mud pipe of adopting, and therefore allows the big relatively mud degree of depth of adopting.This purpose realizes through the mud pipe of adopting with variable-length.Therefore, adopting the mud position, adopting the mud pipe and can extend to maximum length, this means that adopting the mud operation can carry out at big relatively degree of depth place.On the other hand,, adopt the mud pipe and can be in minimum position, be used for storage, can not give prominence to respect to the hydraulic suction dredge hull in resting position.In specific embodiment, the length of adopting the mud pipe can change between 50% and 100%, in other words, the length of adopting the mud pipe that is in minimum position can be in maximum length stretching, extension the length of adopting the mud pipe 50%.
Preferably, plumbing installation is provided with the plumbing installation part, and said part can move along the longitudinal direction of adopting the mud pipe relative to each other.By means of reliable structure is provided, it can bear hard relatively base material part, and said base material is partly aspirated through plumbing installation, and plumbing installation part can have the characteristic of rigidity, and in can telescopically being contained in each other.Preferably, internal pipe arrangements partly has outward extending flange, and the external pipe device partly has the flange that extends internally, said flange in the extended position of plumbing installation each other against.
In this layout, adopt the resting position length of mud pipe and adopt the mud position length by qualification well.In addition, the facing surfaces of flange can comprise sealing device.Therefore, adopting the mud position, the plumbing installation part is relative to each other by sealing well, thereby pressure required in the mud pipe is adopted in maintenance.
As stated, the plumbing installation part is implemented in such a way, and promptly they are scalable.In this respect, same, framework is provided with frame part, and said frame part can move along the longitudinal direction of adopting the mud pipe relative to each other.Preferably, each frame part comprises the longitudinal extension bar, and in such a way, promptly the bar of the bar of one of them frame part and another frame part is relative to each other through roller/roller track system support.When these parts were moved relative to each other, these rollers/roller track system provided low friction and so the less resistance between the frame part.Equally, low wearing and tearing and better stability have been obtained.
In a specific embodiment, the bar of a frame part supports through the sliding bearing system with the bar of another frame part relative to each other.This sliding bearing system comprises: slide rail and sliding part, thus low friction is provided, utilization simultaneously even simple more mode support framework relative to each other.
Usually, what be fit to is the elongation that the mud pipe is adopted in acquisition, and it is big as far as possible on the one hand, remains on the stability that is fit in stretching, extension and the punctured position simultaneously on the other hand.This means: equally in extended position, certain overlapping should the maintenance between the frame part.Good compromise can the realization in one embodiment between these two conditions; According to this embodiment; Each bar is at its a wherein end place carrier roller; And at its end opposite place carrier roller track, said bar is provided with in such a way in pairs, and the roller track of a bar in the promptly said paired bar contacts the roller of another bar in the said paired bar.
Roller Shaft is with respect to the longitudinal direction transversal orientation of adopting the mud pipe.Preferably, roller track is arranged on I shape section bar or the T shape section bar.The flange of a section bar of at least one roller contact, and at least two rollers contact the opposition side of the web of said section bar.Preferably, two rollers contact with the flange of said section bar, and a roller is arranged on each side of the web of said profile.In addition, the bar of a frame part is positioned in the bar of another frame part.In this respect, preferred, inner shaft comprises the band of substantially flat, and external crossbar comprises the roughly profile of U-shaped, and the shank of said U-shaped profile is facing to the band of said substantially flat.For limiting frame part amount of movement relative to each other; And in order to keep the required stability of suction tube in the extended configuration; Each of the bar that comprises a frame part and the bar of another frame part is to comprising abutment means, and said abutment means defines the extended position of adopting the mud pipe.Similarly, each of the bar that comprises a frame part and the bar of another frame part is to comprising abutment means, and said abutment means defines the punctured position of adopting the mud pipe.According to preferred embodiment, each frame part comprises at least three longitudinal extension bars longitudinally.Bar in the inner frame part passes through in the interconnective situation of trussed construction the highly stable embodiment that has obtained to have limited weight.Similarly, the bar of external frame part can interconnect through trussed construction.
Preferably, adopt the mud pipe comprise at least two pivot to connect adopt mud plumbing installation part, the mud tube portion is adopted on said top of adopting the mud pipe or the end is connected to the hydraulic suction dredge hull, and other adopt the mud tube portion at least one have variable-length.Equally, adopt the mud pipe comprise at least two can pivot connect adopt the mud tube portion, said of adopting in the mud tube portion is being carried suction pump, and another is adopted the mud tube portion and has variable-length at least.The present invention further describes below with reference to the embodiment that adopts the mud pipe shown in the drawings.
