Should notice that rubber pad 150 and 151 is along being installed by the end face of connecting device bonded assembly left and right sides hull 101 and 102 bottoms.Therefore, when cargo hold cut out, rubber pad 150 and 151 kept watertight.

There is the connecting device 115 of said structure how to lock and relax and to describe in detail hereinafter.

In the state shown in solid line in Fig. 9 and 10, connecting device 115 lockings, the electromagnetic valve 137 of oil hydraulic circuit is on the neutral position, and A position and T position are connected.Under this state, the fluid of pressurization is full of in other cylinder chamber 130a of branch of oil cylinder 122 and 123 and 131a, and two cylinder chamber 130b and 131b and fuel tank loop 139 are connected simultaneously.Piston rod 124 and 125 rests on the position of protracting.So and piston rod 124 and 125 bonded assembly jig arm 118 and 119, be clipped on the metal piece 117 on the graphic position.Simultaneously, be full of fluid among the cylinder chamber 132a of clamping oil cylinder 126, cylinder chamber 132b is connected with fuel tank loop 139.Therefore, clamping oil cylinder 126 reaches the position of protracting, and its tight lock part 126a is corresponding to jig arm 118 and 119, is being clipped on the metal piece 117 on the graphic position.Simultaneously, be full of fluid among the cylinder chamber 132a of clamping oil cylinder 126, cylinder chamber 132b is connected with fuel tank loop 139.Therefore, clamping oil cylinder 126 reaches the position of protracting, and its tight lock part 126a is corresponding to jig arm 118 and 119 lockings, makes it and can not rotate.

If need jettison the cargo in the cargo hold 105, the teleswitch in the equipment compartment 116 be pushed on the position of " opening ".Because the above-mentioned running of teleswitch, electromagnetic valve 137 be to the right-hand conversion of Figure 11, P position and A position, T position and B position are connected to each other.As a result, oil pressure infeeds the cylinder chamber 132b of clamping oil cylinder 126 from pipeline 136, and the pressurization fluid among the cylinder chamber 132a returns into fuel tank pipeline 139 simultaneously, thereby clamping oil cylinder 126 is retreated, and separates with jig arm 118 and 119, and jig arm is recovered rotating state.Simultaneously, oil pressure is supplied with to the respective cylinder chambers 130b and the 131b of oil cylinder 122 and 123, and the oil pressure among each cylinder chamber 130a and the 131a is return fuel tank pipeline 139.Then, piston rod 124 and 125 is also corresponding returns.Along with stepping back of piston rod 124 and 125, as previously mentioned, because jig arm 118 and 119 is unclamped from the locking of clamping oil cylinder 126, jig arm 118 clockwise rotates in the rotating shaft of bolster 120, jig arm 119 rotates counterclockwise in the rotating shaft of bolster 121, shown in long and short dash line among Fig. 9, thereby the clamping on metal piece 117 is removed with junction surface 118b and 119b.

When the hydraulic actuating cylinder 112 that is located at left and right sides hull 101 and 102 when driving stretches out piston rod 124 and 125, simultaneously the connection of connecting device 115 is removed, hull 101 and 102 rotates, and the hull end at the bottom of the open gradually barge is so metal piece 117 is deviate between jig arm 118 and 119.

After the jettison, when cargo hold 105 cuts out, hydraulic actuating cylinder 112 is driven, close the bottom of hull 101 and 102.Bottom end when hull 101 and 102, when closing by rubber pad, metal piece 117 reaches on the limit of left hull 101, on the position between the jig arm 118 and 119 shown in Fig. 9 long and short dash line.Then, the connecting device off switch is pushed on the position of " pass " by remote control, electromagnetic valve 137 turns to the left of Figure 11, and P position and B position are connected, and T position and A position are connected.So, in oil cylinder 122,123 and 126, to supply with hydraulic pressure, or extract hydraulic pressure out from the inside, situation is open opposite with cargo hold, and piston rod 124 and 125 protracts.Clamping oil cylinder 126 also advances.At this moment, oil pressure is supplied with to oil cylinder 122 and 123 by the sequentially-operating valve 135 in the conduit 134, promotes piston rod 124 and 125, supplies with to clamping oil cylinder 126 then, and clamping oil cylinder 126 just also advances.So opposite direction was rotated when jig arm 118 and 119 was correspondingly open with respect to cargo hold, was not subjected to the obstruction of clamping oil cylinder 126. Junction surface 118b and 119b clamping metal piece 117.Then, clamping oil cylinder 126 advances between jig arm 118 and 119, and is locked.When clamping oil cylinder 126 passes through preset distance forward, arrive locked position, after limit switch 143B predicted, electromagnetic valve 137 was transformed into neutral position automatically, kept clamp position.

The present invention that need not go into the details is not subject to the foregoing description, and can be revised as the structure in Figure 12 and 13, and its left and right sides hull 101 and 102 can be with respect to fixed hull 103 and 104 rotations.In other words, in embodiments of the invention shown in Figure 12 and 13, fixed hull 103 and 104 left and right sides part with hinge 160 and 161 and the upper end of left and right sides hull 101 and 102, are done rotatable connection.In addition, for left and right sides hull 101 and 102 is opened and closed, the upper deck in each fixed hull 103 and 104, and between each left and right sides hull 101 and 102 bottoms, a hydraulic actuating cylinder 162 is set.As shown in figure 13, the base of hydraulic actuating cylinder 162 is done rotatable installation on fixed hull 103 or 104, and simultaneously, the end of the piston rod 162a that stretches downwards of hydraulic actuating cylinder 162 is installed on the peristome of left and right sides hull 101 and 102 bottoms.Therefore, if piston rod 162a stretches out, hull 101 and 102 is pressed shown in the long and short dash line among Figure 13 and is moved, and opens cargo hold 105.On the contrary, cargo hold 105 cuts out when piston rod 162a retreats.

Therefore, connecting device of the present invention is best suited for carrying barge left and right sides hull is connected, and the hull of this barge, separates as two-door along center line at tank top.As mentioned above, the connecting device that two sectional mo(u)ld carrying barges of the present invention use has one a pair of jig arm of Driven by Hydraulic Cylinder and the assembly of a fluid power clamping oil cylinder used respectively wherein arranged, and the relative both sides of metal piece are by the powerful clamping of this two jig arm therein.In addition, on a part of clamping oil cylinder, consubstantiality forms a tight lock part, is engaged by two jig arm, thereby jig arm can be locked on clamped position forcefully, prevents the jig arm rotation.Therefore, in the present invention, because left and right sides hull has connecting device to do strong connection, connecting device center line at the bottom of the barge is pressed preset space length and is arranged, so stable water-proff packing can be obtained in the open place at the bottom of barge.Therefore, compared with the prior art, can make cargo hold longer, increase a lot of carrying capacitys.In addition, by using the switch remote control, connecting device is easy to handle.

Figure 14 to 16 show the present invention open two amalgamation carryings of die bed barge cargo hold remodeling for example.

Shown in Figure 14 and 15, there is a plate shape rubber pad 201 to be located at the top of open portion upper surface, the angle of pre-determined tilt is arranged at the bottom of open portion and the barge.And, below rubber pad 201, being provided with hollow rubber pad 202, the inside fills liquid or gas.At the foot of open portion, tubular rubber pad 203 is set.Above-mentioned packing device is arranged in the cargo hold.When in barge, loading sand and so on, open portion is closed and locked.At this moment, rubber pad 201 and 203 contacts with other lower surface of open portion.Then, inject water or air in rubber pad 202, rubber pad 202 is crushed on the facing surfaces 205.Then, sand is loaded.When jettisoning cargo-carring sand as need, lower the pressure in the rubber pad 202, rubber pad 202 shrinks.Open then open portion jettisons sand.Rubber pad 201,202 and 203 usefulness elastomeric materials are made.For example, with rubber or synthetic resin etc., can increase the reinforcing material such as cloth sometimes.

Therefore, the sand of carrying can slide along the apparent surface 205 of opening section, presses predetermined angle incline at the bottom of open portion and the barge, and with sand from the vertical situation about setting of open portion relatively, can reduce the impact to barge when throwing sand.Therefore, most sand can be stopped by last rubber pad 201, the unlikely open portion that unexpectedly skids off.

Primary elastomeric pad 202 is hollow, as shown in figure 15.Therefore, when water or air being pressed into pad 202, the pars intermedia 210 mountain shape projections of primary elastomeric pad 202.Therefore, primary elastomeric pad 202 can adapt to the extensive variation of thickness.Even in rolling or pitching, during variable in distance between the open portion upper and lower surface 204 and 205, the primary elastomeric pad can adapt to variation fully.

Because press predetermined angle tilt at the bottom of open portion bottom and the barge, so though and contact with sea water, to compare with the situation of lower vertical in hull bottom, the less impact of seawater is accepted in the bottom.Especially play rubber pad 203 can prevent seawater intrusion barge.

As mentioned above, in cushion device of the present invention, rubber pad 201 can prevent the unexpected cargo hold that flows out of sand and so on, and rubber pad 203 can prevent that seawater immerses barge, and primary elastomeric pad 202 can guarantee sealing effectiveness.And, because the surface of open portion and hull bottom tilt, thus when with sand when open portion is launched, the impact of barge is reduced, cause reducing damage to filling up.Because when throwing sand, primary elastomeric pad 202 shrinks, big portion is by rubber pad 201 shieldings, and primary elastomeric pad 202 can be avoided damaging.In addition, cushion device reaches 203 with three rubber pads 201,202, and the more new capital of each is very convenient, therefore can shorten the suspending time that barge is changed the pad part.

In recent years, environmental pollution has become important social concern, so the barge navigation time will prevent definitely that the sand of carrying etc. from will releasing.For cost saving, be sought after sand and so on is once transported in large quantities, and be transported into the shallow sea simultaneously simultaneously.Therefore, though require the height of carrying barge little, width and length are big, and this carrying barge is subject to the influence of roll and pitch, and therefore, strong request has effective cushion device that can bear roll and pitch.Cushion device of the present invention is sure to satisfy above-mentioned requirements.

Though the present invention is proved absolutely with reference to accompanying drawing in conjunction with most preferred embodiment, should note allly being familiar with this area person and all can making variations and modifications.This class variation and modification should be understood, except that exceeding the accompanying Claim book, the scope that it defines all should be belonged to.
