The present invention program partly constitutes by two, first loading bulk goods in ship new process, and it two is to implement the used special-purpose bulk shipping tool of new process.

The characteristics of new process of the present invention are that the wharf apron does not have the bulk goods accumulation, its particular content is with normally used bulk goods truck changing of design, become the vehicle-mounted hopper for bulk cargo of drag slab, loading bulk goods in ship technology becomes: the loading of stock ground, rear, through the level transportation hopper is dragged to the wharf apron by trailer, directly in the ship storehouse, unload with the suspender hopper of slinging, in the horizontal transportation of hopper, bulk goods is measured.Technology of the present invention and conventional process flow compare scheme drawing as shown in Figure 1.

The designing requirement of the special-purpose bulk shipping tool of the present invention is that capacity is big, and haul lifting control and unloading are convenient.The design's content is by a kind of large-scale hopper of the specifications design of van container, and lifting is four rope controls, unloads in the ship Hatch Opening unloading mode of taking to tumble.Its concrete design plan is as shown in Figure 2:

The description of the drawings:

Fig. 1 is that scheme drawing is compared in technology of the present invention and traditional loading bulk goods in ship technological process.

Fig. 2 is a kind of embodiment design diagram of bulk shipping tool of the present invention.

Fig. 3 is a hopper transit condition scheme drawing.

To graphic explanation:

Ship Hatch Opening 1, bearing 2, pole 3, hopper groove 4, eccentric shaft 5, paraxial horizontal side channel helps 6, the horizontal side channel of axle far away group 7, inner reinforced plate 8, outer gusset 9, Horizontal Branch guard bar 10 vertically props up guard bar 11, snap ring 12, rope 13, quick hook 14, suspender rope 15, suspender 16.Figure 1A shows old technology, and Figure 1B shows new process.

In conjunction with the accompanying drawings loading bulk goods in ship technology of the present invention and special-purpose bulk shipping tool technical scheme are further given explanation:

As shown in Figure 1, unloading operation in nonexistent code head forward position in the technology of the present invention.Bulk goods to the wharf apron, directly is discharged into goods ship storehouse with suspender through level transportation operation in hopper is packed in the stock ground, rear into.Instrument of the present invention has tangible advantage: the wharf apron does not have the bulk goods accumulation can make multiple ship kind operation simultaneously in the same berth, and conversion ship kind is not subjected to the restriction of bulk goods operation therebetween, has improved the harbour degree of utilization.No bulk goods is piled up the environmental pollution that can also avoid some bulk goods to bring.Available electron weighbridge metering in the horizontal operation process of hopper simultaneously becomes manifest to offer the owner of cargo and shipowner data print-outes such as date of contained bulk goods, time, gross weight, net weight, reduces gauging loss.

As Fig. 2, shown in Figure 3, the special-purpose bulk shipping tool of the present invention comprises two parts, the large-scale hopper for bulk cargo of the first, and its two Hatch Opening unloads shelf.Hopper for bulk cargo of the present invention a kind of simple, practical design plan as shown in Figure 2, its structure comprise one long, wide, the bucket 4 that high standard is identical with van container, in the vertical two ends of the hopper ledge outside concentric eccentric shaft 5 is arranged, paraxial horizontal side channel helps 6 perpendicular to bottom land, the horizontal side channel of axle far away is helped 7 flares, become the obtuse angle with bottom land, ledge has the reinforcing gusset, vertical gusset 8 is arranged in the ledge 6, and the outer vertical gusset 9 of ledge 7 is become one with a guard bar 10,11, Horizontal Branch guard bar 10 is on the position of same horizontal surface with bottom land, snap ring 12 is equipped with in vertical guard bar 11 upper end that are positioned at four jiaos of ledges, has length to approximate the connection rope 13 of hopper height on the snap ring 12, and rope 13 free ends have quick hook 14, suspender has four suspention ropes 15 for 16 4 jiaos, can articulate fast with rope 13 usefulness hook 14 or separate.Hatch Opening unloads shelf and supports by two groups of bearings 2 that are placed on ship Hatch Opening 1 both sides with by bearing 2, and crossbearer constitutes in the pole 3 in the ship Hatch Opening sky.The using method of the design's shipping tool is, the design's hopper is placed on the van container transport trolley, the goods yard is contained in bulk goods in the hopper in the wings, by directly being transported to the wharf apron after the electronic loadometer metering, directly winch to the ship Hatch Opening with suspender from transportation, eccentric shaft 5 load on pole 3, is loosened the suspender hopper with self lay particular stress on from 90 ° of the horizontal lateral wall 7 direction tippings of trend axle far away, and the interior bulk goods that will struggle against all is discharged in the ship storehouse.The hopper of slinging again is placed on and returns the loading of goods yard, rear on the transport trolley.For ease of connecting suspender 16, on the snap ring 12 of four jiaos in hopper, give the rope 13 that length approximates groove height degree is housed earlier, rope 13 is suspended in outside the groove in transportation, when wharf apron loading and unloading hopper, operating personal just can use quick hook 14 to be connected under transport trolley to free rope 13 and rope 15.The horizontal side channel of design-calculated hopper flare of the present invention group 7, its flare horizontal sextant angle is advisable with 60 °.The Horizontal Branch guard bar can also be used to close a position, and gos deep in the storehouse as need, just as long as turn to 90 ° can accomplish the hopper level.Therefore shipping tool of the present invention has following advantage: at first hopper capacity is big, can load 20 tons of bulk goods, and it is very high to load efficient onto ship, in the wharf apron shipment, a hopper is only used two fens clock times, and one day by work calculating in 18 hours, one pair of suspender can be adorned 10800 tons of bulk goods, be the grab bucket can't than.Next is simple to operate, can be easy to control the job position of hopper with four lifting ropes.The hopper that the 3rd advantage is the design and unload shelf, physical construction is extremely simple, can not produce mechanical breakdown in operation.
