Description

A kind of movable type LNG filling trolley

Technical field

The utility model relates to ports handling machine technical fields, refer specifically to a kind of movable type LNG filling trolley.

Background technique

" construction beautiful China ", " Green Development " Policy Background under, natural gas applications are rapidly developed, especially In recent years, Ministry of Communications carried forward vigorously ship and changes gas engineering, and original oil-burning vessel is changed to LNG Power Vessel, LNG as fuel ratio fuel oil more Add environmental protection.Currently, the country, which has a small amount of ship, is changed to LNG fuel, none formal granted filling harbour built up on the Changjiang river, Several Ship Transportations have also only been carried out in the rare several form trial operations for being intended only as pilot experiment demonstration built up, the transport of LNG tank case Pilot.

Conventional LNG fills harbour process are as follows: LNG storage tank → pump → measuring equipment → loading arm (or hose), according to need It wants, these equipment are all fixed on the different position of harbour, are connected between equipment by steel pipe.Because LNG is low-temperature liquefaction Natural gas, temperature are about -162 DEG C, and pipeline is longer, and heating surface area is bigger, is easy gasification, and pipeline superpressure leads to economic loss even Explosion accident, therefore LNG pipeline will be short as far as possible and strictly carries out cold insulation measure.Existing container terminal generallys use bank Bridge crane loading container, gantry crane can walk back and forth on harbour track in operation process.If a harbour has simultaneously Container handling and the function of adding LNG to ship, then be both needed to be arranged on limited harbour above-mentioned LNG filing provision, pipeline and Gantry crane, walking, the revolution of gantry crane certainly will collide (usually more than 10 meters high) with fixed pipeline and loading arm.

Therefore, it is necessary to improve to existing LNG dosing method, make the basic handling system of port and pier can be simultaneously Meet gantry crane lifting operation and LNG filling operation.

Utility model content

The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, provide it is a kind of it is structurally reasonable, can be simultaneously Meet the mobile LNG filling trolley of gantry crane lifting operation and LNG filling operation.

To achieve the goals above, the utility model uses following technical scheme:

A kind of movable type LNG described in the utility model fills trolley, and for the track that gantry crane uses, the track is equipped with The moving trolley of track-movable, moving trolley are equipped with the filling apparatus of LNG；The filling apparatus includes passing sequentially through pipe LNG storage device, dispenser pump, meter and the loading arm of road connection.

According to above scheme, the moving trolley is equipped at least two LNG storage device, multiple LNG storage devices It is connected in parallel on pipeline, and the pipeline between LNG storage device and dispenser pump is equipped with valve.

According to above scheme, the LNG storage device is LNG storage tank or LNG tank case.

According to above scheme, the filling apparatus further includes the power device that moving trolley can be driven to move along track.

According to above scheme, plugging into for the loading arm is held equipped with emergency separating device.

The utility model has the beneficial effect that the utility model is structurally reasonable, reduces accounting for for filling apparatus to greatest extent Ground area saves investment；Filling apparatus can move integrally, and not influence gantry crane operation, and the same harbour is made to have handling collection Two kinds of functions of vanning and filling；For different type, tonne ship, ship interface position is different, and filling apparatus can be whole Mobile, the problem of very good solution dock with ship, docking is more flexible, conveniently；Pipeline investment is saved, BOG steam is reduced Yield.

Specific embodiment

The technical solution of the utility model is illustrated with embodiment with reference to the accompanying drawing.

As shown in Figure 1, a kind of movable type LNG described in the utility model fills trolley, for the track 1 that gantry crane 11 uses, The track 1, which is equipped with, to be equipped with the filling apparatus of LNG along the moving trolley 2 that track 1 moves, moving trolley 2；The filling Device includes LNG storage device 21, dispenser pump 22, meter 23 and the loading arm 24 for passing sequentially through the connection of pipeline 25；The shifting Dynamic trolley 2 can be by plate vehicle refitting, and the specification of moving trolley 2 is determining according to the specification and quantity of filling apparatus, moving trolley 2 It self power equipment can be used to be driven, or realize moving along track 1 using the traction facility on harbour；It is loading and unloading When LNG, by one end of 11 moving track 1 of gantry crane, filling apparatus is moved to by plugging into a little for ship, handling by moving trolley 2 After arm 24 is connect with ship, LNG is filled on ship by dispenser pump 22, dispenser pump 22 also can be reversed operation and store to LNG Device 21 carries out fluid infusion；Existing port and pier infrastructure can be used in the utility model, by existing 11 track 1 of gantry crane Moving trolley 2 is set, makes the realization of LNG filling apparatus that can be moved to corresponding position along track 1 and carries out filling operation, 11 operation of gantry crane When moving trolley 2 is transferred to 1 other end of track, to realize the compatibility of the handling of gantry crane 11 and LNG filling, it is defeated to shorten LNG Pipeline is sent, the investment of basis instrument is reduced；Likewise, moving trolley 2 can be used tire as move mode, thus not having It is used on the port and pier of 11 track of gantry crane, so that LNG storage device 21 and filling apparatus are moved to ship interface position.

The moving trolley 2 is equipped at least two LNG storage device 21, and multiple LNG storage devices 21 are connected in parallel on pipe Pipeline 25 on road 25, and between LNG storage device 21 and dispenser pump 22 is equipped with valve 26, and the moving trolley 2 can basis The capacity and ship adding amount of LNG storage device 21 and frequent degree are arranged, and pass through one or more LNG storage devices 21 Moveable LNG storage system is constituted, the connection of pipeline 25 between multiple LNG storage devices 21 is controlled by valve 26, Guarantee that dispenser pump 22 can carry out fluid infusion or reverse operating to any LNG storage device 21.

The LNG storage device 21 is LNG storage tank or LNG tank case, when LNG storage device 21 is horizontal LNG storage tank, LNG storage tank is as the fixation means in moving trolley 2, and when needing fluid infusion, the movement that LNG is transported to harbour using groove tank car is small On 11 side of vehicle, fluid infusion is carried out to LNG storage device 21 by dispenser pump 22；When LNG storage device 21 is LNG tank case, can adopt It with the mode of the single tank case of integral lifting, is pulled away using truck, rechanges the LNG tank case full of liquid, LNG tank case can also use The fluid infusion mode of storage tank, making the source LNG of the utility model, there are many selections to improve using flexible.

The loading arm 24 can also use hose, and loading arm 24 or plugging into for hose are held equipped with emergency separating device 27。

The loading system is unloaded in addition to major function except satisfaction to ship filling and tank wagon, also needs to be equipped with pipeline, storage The inherently safe safeguard function of the auxiliary such as tank superpressure emergency discharge.

The movable type LNG filling trolley can also be independently arranged on filling harbour, that is, pass through the mobility of itself Realize the function of filling to ship.

The movable type LNG filling trolley is equally applicable to store, fills other fluids, only need to be according to added beam body Characteristic matches corresponding material.

The above description is only a preferred embodiment of the present invention, therefore all according to described in the utility model patent application range The equivalent change or modification done of structure, feature and principle, be included in the scope of the utility model patent application.
