Abstract

The present invention provides the unloading equipment of the flat top barge (1) that one is used for having deck (2), and at least one of which service water outlet (8) be located at deck (2) place, among or on be present in the sand on barge (1) for sliming or flushing。

Description

Discharging method for flat top barge

Technical field

Provide a kind of unloading equipment for flat top barge。Provide the unloading equipment of a kind of flat top barge for having deck more precisely。The present invention also includes the discharging method of barge。

Background technology

" flat top barge " is defined herein as the barge with close sea horizon or its loading deck on sea horizon。Flat top barge can be conventional non-self boat or self propelled barge。

So-called " flat top barge " with the generally flat deck as loading space uses extensively and is readily available。It is known that such barge is equipped with retaining wall upwardly extending from deck。Retaining wall is generally proximal to the location, edge on deck。

When being used for transporting sand to be such as used for making up land from sea, it is possible to by fluidisation sand pump being delivered on deck, simultaneously when sand on deck upper time excretion load barge from the remaining water of sand。Typically by typically form in slit perforation or by the geotextiles in retaining wall by deck or the agricultually-oriented perforated pipe on close deck drain。

According to prior art by using earth-moving equipment (such as excavator or loading shovel) to unload sand from barge。Have turned out this discharging method than relatively time-consuming and cost is high。

Summary of the invention

It is an object of the invention at least one overcoming or reducing in the defect of prior art。

This purpose is realized by the feature in such as description below and disclosed in following Patent right requirement according to the present invention。

Provide the unloading equipment of a kind of flat top barge for having deck, at least one of which service water outlet be located at deck place, among or on be present on barge for sliming or flushing sand。

By service water outlet is located at deck place, among or on, the water supplied by service water outlet will flow in the sand on deck and sliming or rinse sand。If service water outlet positions near deck, then water will enter sand at lower position, and water will tend to sliming sand rather than rinse sand。Service water outlet can include flow regulator, for instance hole or valve。

Service water outlet can with location above deck, under or on pipe connect。Pipe can have the multiple service water outlet that can be positioned on deck in like fashion, therefore provides the low cost of unloading equipment to select。More than one pipe may be advantageous in that, particularly on relatively nuggar。

Service water outlet can be supported by the equipment independent of barge。It is placed in the fixing or suspension portal frame system on barge or on adjacent barges or excavator such as can have for supporting service water outlet and tube-like piece。

Should be appreciated that and depend on its position relative to barge, service water outlet is likely to the connection requiring over pipe and/or tube-like piece may be connected to water pump。Water pump can be positioned on barge or outside。If being positioned at the outside of barge, then water pump can be better adapted to serve more than one barge, and reason is that water pump is only in being connected to barge during unloading operation。

Flat top barge can have at the retaining wall loaded and during transport to be maintained on barge by sand in place。Can tiltable maybe can removing so that being unloaded by fluidisation sand at least partially of retaining wall。

Retaining wall or deck can have for discharging the fluidisation of the outside leading to barge or being rinsed the opening of sand。In order to load purpose, particularly when using fluidisation to load, opening should close。Need not be able to close to unload purpose opening。

Can close opening can equipped with valve。Any kind of valve being suitable for this purpose can be used。Valve can be remotely controlled by such as hydraulic jack。

Providing a kind of method for unloading sand from the flat top barge with deck, wherein the method includes:

-deck place, among or at least one service water outlet is provided；

-service water outlet is connected to water pump；

-pumped water in sand for sliming or flushing sand by service water outlet；And

-allow sliming sand flow go out deck。

As it has been described above, service water outlet is connected to water pump usually by least one pipe or tube-like piece。

Barge can have retaining wall and the method may include that

-opening is provided in deck or retaining wall；And

-allow fluidisation or be rinsed sand and flow through opening。

Unloading equipment and method according to the present invention provide for unloading the time of sand and being substantially reduced of cost from flat top barge, wherein propose to use relatively simple equipment。

Accompanying drawing explanation

Hereinafter, the example of preferred equipment and method is explained with reference to the accompanying drawings, wherein:

Fig. 1 shows the perspective view of the flat top barge with the equipment according to the present invention；

Fig. 2 shows the pipe with service water outlet with greater proportion；

Fig. 3 shows the opening in the retaining wall of barge, and wherein valve is positioned at opening part；

Fig. 4 shows the perspective view of self propelled barge；

Fig. 5 show schematically show and is positioned at the front view carrying the barge under the door frame of service water outlet；And

Fig. 6 show schematically show the front view of the barge of contiguous another barge location with the excavator carrying service water outlet。

Detailed description of the invention

In the drawings, accompanying drawing labelling 1 represents the flat top barge with deck 2。Deck 2 is closed and for loading and being maintained at deck 2 by sand in place during transport from the upwardly extending retaining wall in deck 24。

Pipe 6 is centrally positioned on deck 2 in FIG。Pipe 6 along its length equipped with multiple service water outlet 8。Service water outlet 8 is shown in fig. 2 with the form of flange bolt pipe 10。

Pipe 6 is connected to not shown water pump by the tube-like piece 12 of the form being preferably pipe during unloading。

Retaining wall 4 is with being used for discharging multiple openings 14 of sliming sand。Therefore each opening 14 with valve 16 and can close in the preferred embodiment。Valve 16 pivotably and is operated by hydraulic jack 20 around hinge 18。In figure 3, valve 16 is shown at open position。

When unloading lash, pipe 6 is connected to not shown water pump via tube-like piece 12。Water is pumped in sand by service water outlet 8, with fluidisation sand。Valve 16 is opened, and allows fluidisation sand flow out barge 1 via opening 14。

In FIG, the end of retaining wall 4 is shown at obliquity to provide the opening 14a for discharging fluidisation sand。

Fig. 4 shows equipped with the self propelled barge 1 with the identical device shown on the barge 1 in Fig. 1。Self propelled barge 1 has deck building 22。Self propelled barge 1 is well suited for be had water pump in not shown ship and provides water for for service water outlet 8。

Door frame 24 on float 26 is equipped with relative to the moveable service water outlet 8 of door frame 24。Service water outlet 8 is connected to tube-like piece 12, referring to Fig. 5。

Service water outlet 8 is shown on the excavator 28 that carried by independent barge 30 in figure 6。Door frame 24 and excavator 28 are the examples of support equipment 32。

When allowing water flow through the service water outlet 8 shown in Fig. 5 and 6, water tends to rinse the sand on ship。
