Description

High ship is by the ferry boat of low bridge

Name of the present utility model is called the ferry boat of high ship by low bridge, particularly a kind of ten thousand tons of seagoing vessels is sailed in the ferry boat cabin, again the ferry boat that passes through under the bridge.

Bridges such as the Nanjing Yangtze River Bridge of China, because headroom is low excessively, bigger steamer is promptly hindered by bridge, and this golden waterway of the Changjiang river can not be made full use of.The cargoes imported and exported at above each harbour, Nanjing are forced in the following transit in Nanjing, and are time-consuming many, and the expense height is unfavorable to importing and exporting and utilizing foreign capital.Over past ten years, some experts have proposed several and have transformed the scheme of bridge, all because of investing former thereby not enforcements such as excessive.

It is low, easy to use that the purpose of this utility model provides a kind of cost, at the ferry boat that ten thousand tons of seagoing vessels are passed through under the bridge smoothly.To achieve these goals, the utility model by the required underbridge clearance of bridge, is not to extend upward from the water surface seagoing vessel, promptly increases the headroom of bridge; But extend downwards from the water surface, promptly reduce the relative height of seagoing vessel, specifically be to allow the ferry boat that is loaded with seagoing vessel sink down into more than 20 meter deep water place, make seagoing vessel in highly near 30 meters cabin, pass through bridge.If more than 20 meter of depth of water out of reach, then to deep-cut ferry boat navigation at the bottom of the river of process.With 24 meters calculating of bridge headroom, the depth of water is 20 meters, and the distance of bridge at the bottom of the river is 44 meters.Suppose that the distance of ferry boat when navigation hull bottom at the bottom of the river is 0.5 meter～0.8 meter, the thickness of ferry boat hull bottom is by 1.2 meters calculating, the seagoing vessel hull bottom is by exceeding 0.2 meter calculating of the ferry boat bilge, then the distance of seagoing vessel mast at the bottom of the river is: 40+0.2+1.2+0.8=42.2 (rice), (44-42.2=1.8 rice), 1.8 meters safe clearance is still arranged, and the ferry boat that loads 40 meters high seagoing vessels can pass through under bridge smoothly.

The high ship of the utility model is that existing steamer transformed formed by the ferry boat of low bridge.The steer of existing steamer, power plant, propulsion equipment and rudder for ship etc. all can remain unchanged substantially, but will put into the melting pot cabin.Improved cabin comprises that driving compartment, two piggyback pods, balance cabin, seven places, four increase the weight of the cabin and the formations such as hopper at top, cabin are increased the weight of in the balance cabin.Each cabin all separates fully, and is not connected.

The high ship of the utility model will load ten thousand tons of seagoing vessels belowdecks by the ferry boat of low bridge, is a buster, could pass through smoothly under bridge and this buster must absorb water more than 20 meter.Can this buster sink down into more than 20 meter deep water place, is the utility model key of success.Reach this purpose, will take following measure to the design of ferry boat: one will dwindle the volume of load compartment and piggyback pod as far as possible, reduces displacement.Two the time select cheap off-grade steel for use as far as possible in design except that key position, with adding plate iron or multilayer steel plates, increasing the weight of steel or many steel reach designing requirement, in a word, steel are heavy more just good more.The 3rd, for ferry boat adds weight, this is topmost: at first add weight for hull bottom, promptly building one has certain thickness iron and steel weight to account at the bottom of the iron and steel concrete boat that most of weight concrete accounts for fraction, way is the framework that is welded into hull bottom with the girder steel steel, be embedded in the framework side of a ship steel plate of each cabin and firm welding, clog in the framework with wastes of iron and steel then, and fill up as far as possible, just use concreting at last.Next is to build to increase the weight of the cabin.Increasing the weight of to there is no the cabin in the cabin, is filling one deck broken iron in the cabin, builds a layer concrete, and filling one deck is built one deck, until the top.The height that increases the weight of cabin height and two layer equilibration cabins equates.The 3rd, in load compartment, build and increase the weight of layer.Load compartment is an oblong, and cargo-carring seagoing vessel is a Long Circle, and particularly edge has certain space between the two, and casting concrete is also floating again at edge filling wastes of iron and steel.In a word, the ferry boat that loads seagoing vessel is handled up under river regulates in the balance cabin, can be sunk down into more than 20 meter deep water place and can arbitrarily float, just reach designing requirement.

Main body of the present utility model is a load compartment, is made of main cabin and deck store two parts.Deck store is actually the hatch door door leaf of a huge arbitrarily switch of load compartment, and two sides of a ship and hull bottom that this door leaf is installed have been exactly doorframe naturally.Because load compartment does not only have loam cake but also do not have the deck, this is a doorframe that does not have upper beam.After deck store is opened, there is not upholder between two sides of a ship, can this make the distance between two sides of a ship change to some extent? can not change in general.If the problem of truly having, upholder still are soluble.And upholder is still arranged in the incipient stage of building load compartment, and promptly be welded between two sides of a ship with several huge steel, must amputate afterwards but build up.How does main cabin combine with deck store? method is to adorn rotary axle (being the axle of door leaf) in deck store one side, adorns axle sleeve on the side of a ship of main cabin one side, the axle threading axle sleeve of deck store promptly become can switch deck store.Adorn several huge spring locks at the opposite side of deck store, the spring lock keyhole of the equal number of opposite side master cabin side of a ship dress.Close deck store, spring lock is about to deck store and tightly is locked on the side of a ship of main cabin, constitutes a complete load compartment.This side deck store bottom dress wheel, wheel moves on the steel plate that the load compartment bilge extends during the switch deck store, and the length that steel plate extends slightly is longer than the width of deck store.Main cabin two sides of a ship and the bilge and deck store have three joint portions, intake in the cabin from the joint portion unavoidably after closing deck store.To respectively inlay an inflation caulking joint leakproof rubber pneumatic bag in three joint portions in main cabin for this reason.Every slat gum air bag has an air inlet pipe and freeing pipe, and each air inlet pipe is connected with big freeing pipe with a big air inlet pipe respectively with freeing pipe.Big air inlet pipe is connected with the charging blower that is contained in side of a ship eminence; Big freeing pipe one valve that end is adorned is positioned at side of a ship eminence.Close deck store also for after the inflation of leakproof rubber pneumatic bag, three joint portions are tightly seamless, and river can not enter.Before opening deck store, to open big freeing pipe valve earlier and be the venting of leakproof rubber pneumatic bag.This inflation caulking joint leakproof rubber pneumatic bag also is applicable to equipment in some other water.After seagoing vessel drove into main cabin and cuts out deck store, water level and river maintained an equal level in the load compartment, and the relative height of seagoing vessel does not reduce, and can't pass through bridge.Therefore to reduce water level in the load compartment.Method is to adorn four Foldable inflating draining rubber pneumatic bags all around altogether at the bottom of load compartment, entangles air bag with the net of rope braiding and is fixed in the bilge, and inflation back net can extend.Each rubber pneumatic bag has an air inlet pipe and a freeing pipe, and each air inlet pipe is connected with a big freeing pipe with a big air inlet pipe respectively with freeing pipe.Big air inlet pipe is connected with the medium-sized charging blower that is contained in main cabin side of a ship eminence, and big freeing pipe valve is contained in main cabin side of a ship eminence, and the two is by the push-button control in the driving compartment.When seagoing vessel drives into main cabin, be earlier the inflation of Foldable inflating draining rubber pneumatic bag.Charge air depends on the size of seagoing vessel and the depth of drinking water, a gas should be suitably filled in concrete grasp more, water is put less and is easy to replenish in the cabin, need open deck store and be the draining airbag aeration again if water is many, be the inflation of leakproof rubber pneumatic bag again after closing deck store, be the venting of draining rubber pneumatic bag simultaneously, dwindled rapidly and folding being compressed at the bottom of the load compartment by the pressure drainage rubber pneumatic bag of water.This moment, water level reduced greatly, if the seagoing vessel hull bottom is at the bottom of near load compartment suitably.If water level is too low, a water inlet is arranged at the deck store bottom, and can open water inlet is to discharge water in the cabin.The outside shipment of deck store rudder also can be removed rudder for ship from, the course of grasping ferry boat by the speed of two angle of rake start-stops and speed.Should adorn one deck rubber as protective cover at the bottom of the load compartment and around the side of a ship.For preventing that seagoing vessel from colliding in board, respectively adorn a thick rope in two side of a ship bottoms, main cabin, one is long and the other is short, and rope end is respectively adorned the mutual buckled up ring of several energy.After water level in the load compartment reduces, will grow rope stretch around one week of seagoing vessel mast, again with another rope fastening.This moment, rope had certain fixation to seagoing vessel.When flood arrives, water level raises, and all balance cabins function is used up, and ferry boat still can not be reduced to catch siding when following, suitably discharges water in the cabin can open the deck store water inlet, though water level surpasses the degree of depth of seagoing vessel drinking water, seagoing vessel also is difficult to float.This rope can be used as the measure of the interim weightening finish of ferry boat.The height of load compartment should be assumed to 28 meters a little more than the distance of the highest water level that allows navigation overflow stage at the bottom of the river, ferry boat navigation channel.

Two piggyback pod branches of the present utility model are located at load compartment both sides middle front part.The inconvenience of piggyback pod lower floor is used, and can build to adding double-layer, promptly with the wastes of iron and steel filling, uses concreting again.Adorn extra heavy electrical motor on the cement concrete.Propelling unit is installed in the piggyback pod outside.Electricity consumption is used as power and can removes fuel tank from, and the piggyback pod volume is dwindled greatly.Piggyback pod exceeds 2 meters of load compartment, and loam cake is arranged, and hatch door is opened forward, and the hatch door threshold equates with the height of load compartment.After installing electrical motor, the piggyback pod upper width should be dwindled greatly, the ladder of coming in and going out for the people can be installed get final product.Because the ferry boat voyage is short, the navigation channel is fixed, and can select bridge one end again, not necessarily selects main channel, these conditional decisions the ferry boat electricity consumption to be used as power be possible.Electricity consumption is used as power, and will be lower than 0.2～0.3 meter of bridge as trackless trolley car above the navigation channel and set up two power transmission lines, also will adorn two transmission poles as trackless trolley car, can be contained on the preceding side of a ship of load compartment.Electric wire is introduced two piggyback pods and driving compartment from here respectively.

The utility model has balance cabin, seven places, occupies the cooresponding area of ferry boat, the river about 20,000 tons can handled up.The lifting of ferry boat is grasped by the balance cabin river of handling up entirely.Balance cabin, every place is divided into two-layer up and down again, and in fact 14 balance cabins are arranged.About up and down six faces in balance cabin are steel plate.A strip shape intake-outlet is opened at outside steel plate middle part in each balance cabin of lower floor to the top, a strip shape intake-outlet is opened in outside steel plate bottom in each balance cabin, upper strata to the top.14 balance cabins are divided into four groups: 4, three balance cabins of 9,10 3 place lower floors are one group, and three balance cabins, upper strata are two groups; Four balance cabins of 5～8 place lower floors are three groups, and four balance cabins, upper strata are four groups.All adorn a hexahedral Foldable inflating draining rubber pneumatic bag in each balance cabin.The rubber pneumatic bag inboard is fixed on the steel plate of the inside, and the outside connects a steel alloy plate that is slightly less than outside steel plate.The steel alloy plate respectively bores a circular hole for four jiaos, passes four circular holes with four steel rods, four steel rods is welded on the place, nearly four angles of about two steel plates in balance cabin respectively again, makes the steel alloy plate come and go operation along four steel rods.Rubber pneumatic bag in each balance cabin all has an air inlet pipe and freeing pipe, and each air inlet pipe on the same group is connected with big freeing pipe with a big air inlet pipe respectively with freeing pipe.Each big air inlet pipe stage casing dress pipe valve, the other end all is connected with a total inlet pipe, and total inlet pipe is connected with large-scale charging blower.Each big freeing pipe other end dress valve.Open certain big air inlet pipe pipe valve during inflation earlier, start the charging blower inflation again.When inflating for rubber pneumatic bag, air bag is splashed to rise and is promoted the steel alloy plate and move outward, the balance cabin river that promptly spues; When exitting for rubber pneumatic bag, dwindled and the folding gradually steel plate place, the inside that is compressed in by the pressure rubber pneumatic bag of river, the balance cabin then gulps down into river gradually.Therefore, the balance cabin also can be described as boats and ships with gulping down the water water discharge device.The push button of handling the push button of large-scale charging blower and each big air inlet pipe stage casing pipe valve and handling each big freeing pipe valve all is contained in the driving compartment.In the ordinary course of things, only need employ one group and three groups totally seven balance cabins, just can keep the normal operation of ferry boat, other two groups of balance cabin aerificatioies are standby.When the flood arrival, water level is very high, and the degree of depth that ferry boat sinks must be deepened greatly, just need employ other two groups of balance cabins.If load ten thousand tons of seagoing vessels that a sky is sailed, the weight of ferry boat reduces by 10,000 thousands of tons ofs, must employ whole balances cabin.It is more much more difficult than the heavy ship of dress to load clean ship, if collect bridge toll, and clean ship charge more than 5 times of ship of should attaching most importance to.The lifting of ferry boat is not only grasped in the balance cabin, and decision ferry boat whole machine balancing all around.No matter be inflation of balance cabin or venting, the balance that can remain ferry boat has just reached designing requirement.Two layer equilibration cabin height sums are lower than load compartment up and down, about 20 meters high being advisable.

The ability that the ferry boat lifting is grasped in the balance cabin is limited.Overflow stage, water level was very high, still allowed shipping, and the balance cabin water inlet of will all exitting at this moment if still can not make ferry boat sink down into necessary deep water place, will in time be gained in weight for ferry boat.Method is to increase the weight of the top, cabin to build one and push up with wide high 6～8 meters semicircular hoppers along load compartment with the cabin in the balance cabin, and tank divides a plurality of lattice, and lattice dative bottom communicates, and top cover is arranged, and water inlet is arranged above, and water outlet is arranged below.This hopper is only very high at water level, just employ when balance cabin function is used up.Available draft engine is the hopper water filling.Hopper fills with water, center of gravity will reduce the height of hopper as if higher.After the hopper fills with water, if still can not make ferry boat sink down into necessary deep water place, also available additive method (wouldn't write into specification sheets) is the ferry boat weightening finish.In a word, allowing ferry boat sink down into necessary deep water place can accomplish fully.

Driving compartment of the present utility model is built in anterior highest point---the top (anterior hopper height should suitably reduce) of hopper of ferry boat, and height equates with piggyback pod.Driving compartment is the maincenter of ferry boat, and each position of ferry boat, various device are handled by driving compartment, and as the switch of load-carrying deck store, the lifting of ferry boat, navigation, stop and course or the like are handled by the equipment such as push button that are contained in the driving compartment.Between hopper top, driving compartment and two piggyback pods, build two walkwaies.30 meters of driving compartments are high, and ladder is indispensable.The starting point of ladder is the water surface, balance out of my cabin side to build the half inclined ladder, can climb up balance cabin top, other has inclined ladder, can enter the walkway.In order to guarantee safety, being lower than one meter of bridge is the catch siding of ferry boat, and this line is difficult again actually sets up.Because above the navigation channel, be lower than 0.2～0.3 meter frame of bridge two power transmission lines arranged, as long as the seagoing vessel mast is lower than 0.8 meter of power transmission line, ferry boat is promptly below catch siding.

The high ship of the utility model passes through the ferry boat of low bridge as a kind of transportation means, needs starting point and terminal point bus stop.Use a considerable amount of Reinforced Concrete Circular Cylinder, squeeze at the bottom of the river in bus stop waters with being evenly distributed, cylinder exceeds at the bottom of the river about 2 meters, and the top of each cylinder will be on same horizontal surface, bus stop in Here it is the water.Can be parked in numerous concrete columns top reposefully at the bottom of the ferry boat iron and steel concrete boat.
