Abstract

An energy-accumulating hoisting method for raising sunken ship or hoisting over-weight and over-long object is disclosed. Two hoisters are arranged on a salvage ship. Many lifting points are arranged on the sunken ship. The steel cable of hoister serially passes through the single pulleys of 2 lifting points. When each steel cable runs up and down in round trip mode, multiple float boxes are tied in accumulative mode until all the lifting point has the float boxes. Another method is uses of float boxes and sunk balls. When all lifting points have been tied with float boxes and sunk balls, the sunk balls is removed and the sunken shift is raised by the float boxes.

Description

The energy-accumulating hoist method for raising sunken ship or hoisting ultra-long or ultra-weight object

The method of Watership Down ship is salvaged in the accumulation of energy lifting:

The invention belongs to heavy thing technology category in a kind of salvaging water: relate to the method that the Watership Down ship is salvaged in a kind of accumulation of energy lifting.Salvaging the shipwreck ship and the huge heavy object in rivers seabed, is the part nuisance.Can with the cheap expense of utmost dispatch water-bed immersed object salvage to the water surface or in water secret transport, be desirable thing.The object of the present invention is to provide a kind of accumulation of energy lifting to salvage the method for Watership Down ship.A kind of is rope rope accumulation of energy overshot, and a kind of is to float heavy group to ※ device accumulation of energy overshot.It is fast that this method has salvaging speed, do not need big power-lift machine and concealed characteristics of salvaging.

The present invention is realized by following two schemes in order to achieve the above object:

One, be rope rope accumulation of energy overshot:

The method at first is to use the hoist point of cutting, welding or the enough numbers of colligation on ship that is sunken to the seabed or submarine, on the fishing operation ship of the water surface, be provided with two not at the winch at a place, steel of two winch folding and unfoldings is pulled with hoist point and is connected, it is characterized in that in the hoist point that the shipwreck ship is set, in two adjacent hoist points pulley is set, steel is pulled rich two pulleys and is spurred up and down by winch, pull when moving downward at each bar steel, load 2 times to the flotation tank of the initial hoisting force of winch, steel is pulled to make a round trip to build and is added once.Pull when a steel and to build the flotation tank weight add when reaching predetermined weight, a steel pulled build the flotation tank lock hanging add on a hoist point, then another steel is fastened the flotation tank unloading, unloading back lock hanging firmly the single-sheaved block of one group of flotation tank hoist point move on on another hoist point, again accumulation of energy loads again, steel fasten the flotation tank of predetermined weight again lock hanging at second hoist point, so repeat work, the flotation tank of the enough floating forces of lock hanging on all hoist points, when total floating force surpasses ships and light boats in water during gravity, the shipwreck ship can rise automatically.And then finish fishing job.

Accompanying drawing is to salvage heavy ship scheme drawing with the inventive method, salvage process below in conjunction with the accompanying drawing casehistory: the salvaging with atomic submarine is an example: see the in the light of actual conditions colligation or weld a plurality of hoist points of object that figure (1-1) first step makes sinking, if the hoist point of submarine is 40, submarine weighs 14000 tons.It is 350 tons that the average hoisting capacity of each hoist point requires, such 350 tons ^*The 40=14000 ton could satisfy the requirement of salvaging.Every adjacent two hoist points are installed two of single-sheaved blocks, see that figure (1-1) C, D are two single-sheaved blocks, have two to have two in certain distance winch, see E, F among the figure (1-1) on the ship of fishing operation.Steel wire penetrating single-sheaved block C lies in the A point mutually with D on two winchs.The relative midway location A of submarine with the sea level, 2 of B can be relatively up and down under the manipulation of winch, the A point is fastened one of the floating debris (empty fuel tank) of a stretchy under the winch load in the above for the first time, starting winch uses (fuel tank) with 50 tons of floating forces to draw in water-bed C point, at this moment the B point is near the water surface, we again with 2 times to 100 tons of A point floating forces, two (empty fuel tank) makes the B point draw in the bottom under the effect of E point winch, the A point is near the water surface, we add two empty fuel tanks again in the A point, connect the fuel tank of entry for the first time totally three empty fuel tanks, starting the F winch makes the A point draw in the bottom again, at this moment the B point is again near the water surface, we fasten two empty fuel tanks again, add original two totally four empty fuel tanks, start the E winch B point is drawn in the bottom again ... round trip increases by two fuel tanks like this, the A point is increased to till seven empty fuel tanks, at this moment this group floating force is 350 tons, seven one group empty fuel tank is drawn in seabed C point, fasten hoist point with bolt rope wire clips in C, shift C point single-sheaved block in the G point, six empty fuel tanks that B is ordered on the steel rope have arrived the water surface and have dismissed again, and G and D are adjacent single-sheaved block.Come and go the work of pulling colligation flotation tank again, the full flotation tank of 40 hoist points operation colligation all like this, its total floating force is 14000 tons so always.But such work can only last till 39 hoist points, last hoist point operate approach separately.Because if last hoist point adopts same manner, 2 of A, B are in the middle of running job, be that 2 of A, B go in the seawater, floating ability is 350 tons+300 tons=650 tons, rather than 350 tons, that is to say three empty fuel tanks of A point colligation, four empty fuel tanks of B point colligation, total floating force has reached 14000 ton hours, and submarine may be raised and can only reach sea water advanced half and just stopped, and at this moment A point B point flotation tank sky fuel tank all surfaces.This is not a good thing, and the purpose that we salvage is that submarine salvage goes out the sea level or near the sea level, rather than salvages the ship hoisting depth, is sea water advanced half.So need approach separately, this approach is to adopt to float to sink to organize device is finished.

Another problem need to prove for the first time starts winch, make have 50 tons of floating forces (fuel tank is drawn in water-bed C point, and this is that B point runs to the water surface by time a bit, and we use 2 times again to the initial condition flotation tank, promptly 50 tons ^*It is to carry out under the requirement seawater surface for the flotation tank of 2=100 ton floating force (two empty fuel tanks), rather than expose fully on seawater surface and carry out, this has just increased the difficulty of colligation, and terms of settlement is device to be solved like Unwinding chain etc. or with floating heavy the group with the tension equipment class of short distance.

Be safe in operation in addition, the workboat of participating in salvaging must be controlled at the vertical uplift water surface scope that departs from the shipwreck ship a little, also will avoid the bathycurrent influence, certain flotation tank of making provision against emergencies tears hoist point or misoperation makes flotation tank quicken to float liter a collision workboat and an operating personnel.

Also having a problem is to solve shipwreck adhesive ability problem, and so-called adhesive ability is exactly shipwreck or ship and bottom surface, seabed cohesion, the ships and light boats of especially permanent sink part.That is to say at lifting shipwreck or the initial required salvaging hoisting force of ship, the own gravity of overtaking vessel or ship a lot.After shipwreck or ship moved just aweigh, adhesive ability was overcome, and this surmounts power more greatly and can impel whole ship or ship acceleration/accel to impact to the water surface, can make between flotation tank and the flotation tank like this, produce collision between flotation tank and the shipwreck ship, broke off relations; And then make ships and light boats sink to the seabed again, even draw turn over operation on the ship winch and cause the accident.Terms of settlement is to use group to floating sink device.

Two, application accumulation of energy lifting is floated to sink to organize the large-scale naval vessels of device solves is salvaged problem fast:

Can show unfortunate accident on August 13 in 2000 from Russia " Kursk " number atomic submarine, need the quick Refloatation method of invention, with the wrecked officers and men of timely rescue, because speed one is slow, the personnel on the submarine will sacrifice.Our this research also is to respect, inspire and love to the officers and men that are engaged in the submarine military service.So it is exactly " flotation tank and sedimentation ball group are to hoist point displacement ligation overshot " to device that this paper proposes to float heavy group, solves quick salvaging problem.

Flotation tank and sedimentation chou group are replaced the ligation overshot to hoist point: (abbreviation floats heavy group to device)

The salvaging principle is as follows: see that it is 350 tons that figure (1-2) sets the floating force of flotation tank in water, sedimentation ball heavy power in water also is 350 tons so, flotation tank and sedimentation ball is lashed that to form group right together again, and this just is called " floating heavy group to installing ".This device floating force is zero in theory, very easy moving, find heavy ship hoist point earlier that of flotation tank rope rope emptying with rope, block colligation and to hoist point, see figure (1-2) A, and then the cable wire of sedimentation ball and flotation tank cut off to be rolled into see on one side figure (1-2) B, the floating force of flotation tank is just transferred on the heavy ship like this, and heavy ship will have the group logarithm of enough casees and ball just can satisfy heavy ship fishing job.In order to race against time, the general double flotation tank of doing of service tank, the sedimentation ball can be wrapped up in stone sand or prefabricated in advance with materials such as cement with silk screen, also can be temporarily with fine-structure mesh bag silt, make the sedimentation ball that does not add cement ,-but this loose sedimentation ball, must be careful during operation, can not be damaged, otherwise be easy to cause the accident because of damaged.In order to race against time and the minimizing funds, with common fuel tank double as flotation tank, be necessary in order to race against time to leave hidden hoist point device when at this end submarine is made, floating heavy group prepares prefabricated to device in advance, in order to race against time, there is not prefabricated hoist point submarine will imagine the state of submerged submarine in advance and drill chain and adopt different rope rope colligation mode and method.

Float heavy group according to need of work device is had following a few kind: have many packing lists ball group right to, single many balls of case group, single packing list ball group.

Be divided into again according to operation requirements: little float heavy group to, it is little that heavy to float heavy group right.

Have according to operating needs and to be divided into: the short chain group is right to, length chain group, and it is right to organize in pairs, and group is to colligation.

Make answer below respectively:

(1) many packing lists ball group is to little heavy to float heavy group right: see that its flotation tank of figure (1-2) is that seven sedimentation balls are one; It is right to being exactly many packing lists ball group to form group like this, its function is to salvage the operating time in order to save, the flotation tank floating force is hour employing again, the sedimentation ball uses up to throw away to be rolled on one side and does not reclaim, its operation is to carry out the requirement flotation tank at the bottom to organize floating force entirely small in the gravity of sedimentation ball in water, purpose is hidden safety, and little heavy to float heavy group right so also can be called.

(2) single many balls of case group is right: see that figure (1-3) 1 its flotation tank is one, the sedimentation ball is to see figure (1-3) 3 more than two, after the colligation of flotation tank hook is intact, is recovered on the sedimentation polu pony, so that usefulness again, hour is suitable for and reclaim weight-lifting equipment horsepower.The floating heavy group of figure in (1-3) carried out the flotation tank floating force less times greater than sedimentation ball settling capacity to its flotation tank on the sea, little to float heavy group right so also be called.

(3) single packing list ball group is right; Transportation is used all more convenient.With big weight-lifting equipment, put into water with the sedimentation ball floating caisson.

(4) the short chain group is right: see that figure (1-2) is exactly the likeness in form handcuffss type chain that flotation tank and sedimentation ball have only two pairs of weak points.One pair of handcuffss chain is used to connect flotation tank and sedimentation ball, and another pair is empty.After when arriving the ships and light boats hoist point, a connection of empty handcuffss chain hoist point being connected in the B point, again the sedimentation player being put handcuffs on D point of chain and untie, also just finish flotation tank floating force transfer process.

(5) length chain group is right: see that figure (1-4) need often not to know much floating forces when the solution submarine is salvaged fast.At this moment not water inlet of one or several bin of possible submarine, has floating force, if the flotation tank floating force of giving is excessive, crossing most floating force impels whole naval vessels to quicken to rise, can make between the flotation tank and to produce collision and break off relations and fall into the seabed again, partly bury in the seafloor soil at the solution naval vessels, the lift that needs during initial the salvaging, more much bigger than the gravity of naval vessels own, because of must overcoming adhesive ability, in case and when the naval vessels built on stilts, this adhesive ability becomes zero, superfluous floating force also can impel ship very to produce acceleration/accel and rise, and excessive velocities will have an accident.So will be with length chain group to solving this problem.So-called length chain group is right, is exactly that three handcuffss chains are arranged between flotation tank and the sedimentation ball.Long-chain of two short chains.Each end of three chains flotation tank of all ining succession; One short chain and the long-chain sedimentation ball of ining succession is seen figure (1-4), and another short chain is empty, after arriving the ships and light boats hoist point, empty short chain is connected hoist point, and another short chain is untied, and operation is carried out one by one like this, begin built on stilts a little does not just rise when proceeding to whole naval vessels, because of long-chain playing pulling function, at this moment take off long-chain sedimentation ball more one by one, when separating when some, ships and light boats slowly at the uniform velocity rise, and are little state that floats between whole ships and light boats and the flotation tank.At this moment Sheng Xia long-chain group is to rising simultaneously.Could carry out fishing job in a whole skin like this.

(6) organize in pairs right: the ships and light boats that we salvaged surface as required, and above-mentioned fishing job flotation tank is near the water surface time, also on ships and light boats, if require ships and light boats to surface, then must flotation tank transfer to one by one ships and light boats below.It is right to address this problem with regard to needing reformulation to organize in pairs, see that figure (1-5) 3 promptly is right two little groups of floating, the centre sees that with slide fastener figure (1-5) 6 is pulled in together, be pressed in the water, two groups of flotation tanks are straddled bottom at ships and light boats, see figure (1-5), when beginning to do this work, also to consider ships and light boats upper shift of gravity center problem, because of upper shift of gravity center can cause the whole swing of ships and light boats, or the counter-rotating turning over, make ships and light boats sink to the seabed again, in order to prevent accident, part is organized in pairs and can not all be extractd the sedimentation ball, also will increase several Y shaped steel supports and see figure (1-5) 4, Y shaped steel support promptly is to be welded into Y type support with I-beam section or steel pipe with organizing in pairs colligation to be in the same place, Y type support and sedimentation ball and organize to flotation tank colligation in pairs to form little type group of floating right, Y type support and sedimentation ball merge, and one pieces together a part of forming the settled weight composition.At this moment sedimentation ball plays stabilization.On ships and light boats, also to increase column-pressing rope and see that figure (1-5) 7 two ends colligation above Y type frame is firm, to guarantee safety.See figure (1-5)

(7) organize colligation: see figure (1-3) 2 after the hoist point of ships and light boats is determined, each flotation tank progressively increases the number of flotation tank by the winch up-and-down movement, and last seven flotation tank colligations are called group to colligation together.Because will below the seawater plane, carry out during colligation, to float single many balls of case group to device with little, the diver can be with small-sized take-up device little group of floating to drawing in the water, align with original flotation tank, divide two roads to tie up tightly with cellular bundle rope, see that figure (1-3) 2,4 connects with handcuffss chain and flotation tank, hangs up the sedimentation ball more singly on hawser, because of the sedimentation ball is seen figure (1-5) the 3rd, many balls are convenient to reclaim, recycle with small-sized lifting appliance.Cellular hinge 6 points that are banded with: see that figure (1-5) 8 every bits can connect the handcuffss chain link of three directions, be provided with on every handcuffs chain and remove zip and tightly install.This latching device is similar to oil drum colligation locking band, is convenient to dismounting tension colligation.

The secret ship of salvaging a sunken ship fast:

Use fully and float heavy group device.From the Russia Kursk is example, in order to rescue ship person, and must be fast.Taking method is to use fully to float heavy group to device, hoist point is prefabricated, the little heavy type of dozens of is floated heavy group to be hooked on around the own submarine device, secret is transported to shipwreck ship place under water, fishing job is carried out fully under water, and this fishing job is just carried out the hook of chain rope and taken off the work of separating by diving detector manipulator, and all sedimentation balls are all thrown still, when whole ship very presents littlely when floating state, just the lifting of heavy ship is in operation.Within the lifting range of control of submarine, they can secret be transported in water, if there is long-chain to hinder when moving, can forms long-chain and float heavy group to jettisoning, and secret is transported in water.

Two, the crane lifting service of overweight overlength object is carried out in utilization accumulation of energy lifting: the invention belongs to lifting elevator technology category: for overhaul convenient for the purpose of, how to use accumulation of energy lifting method and heavy ship is lifted by crane leave several meters on sea level or tens meters.Perhaps lift an example again, how railway to Tibet uses accumulation of energy lifting method is lifted by crane the bigger train of potential difference to above the plateau with elevator.Perhaps train drops to ground in a whole skin by the plateau.Be example with the train lifting for simplicity: suppose that the configuration of two row train weight equates, one on the plateau one on ground, if have one rationally to suspend the transformational structure device in midair, the first car is fallen potential energy and is reduced, second car rising potential energy improves, loss power only consumes on friction and steel rope resistance to deformation like this, and that is a good thing.Certain two car weight amounts are different, can dispose and carry on a shoulder pole thing in addition, make them be equal in weight, and two cars difference arrives configurable counterweight for the moment and carries on a shoulder pole car in addition.But require very high to overhung construction: the first, guarantee enough tension intensitys; The second, guarantee that not run-off the straight has an accident; The 3rd, it is stressed even to guarantee that every rope rope is in operation; The 4th, it is feasible to adjust installation; This paper proposes accumulation of energy lifting method and uses many Suo Lianhe overhung construction device and lift by crane super large, overlength, overweight object for this reason.

Be example explanation lifting principle with the lifting train below:

Assembly pulley accumulation of energy associating lifting method hoisting heavy.

Accumulation of energy associating lifting method lifting train aufbauprinciple, see Figure of description (1-6): left elevator chamber (36) and right elevator chamber (3) are with intersecting (24,25,28,27) suspended structure cable wire, and coordination (20,26,29) suspended structure cable wire, be suspended on many intersections and coordination as on (23,19) suspended structure fixed pulley.Left and right two elevator chambers can come and go mutually up and down and move under the effect of left winch (40) and right winch (1).

Head in the left elevator chamber lower channel (41) with headstock holding weight one joint railway carriage (about 100 tons) during operation, at this moment starting left winch (40) rises to the end left elevator chamber, right elevator chamber drops to ground, at this moment head in the right elevator chamber lower channel (5) with headstock holding weight railway carriage (about 200 tons) again, restart right winch, right elevator chamber is risen to the end, left side elevator chamber lands, head in the left elevator chamber lower channel (41) with headstock and restart left winch holding weight railway carriage (200 tons) again, left side elevator chamber rises to the end, right elevator chamber lands, and heads in the right elevator chamber lower channel (5) with headstock holding weight railway carriage (200 tons) again, starts right winch again; Continuous like this coming and going, carry out accumulation of energy work, again right elevator chamber lower channel is held the weight railway carriage in the right elevator chamber upper channel and all pull out if the train that will lift by crane driven into, this cries by the displacement of lifting thing and holds weight, this must be carried out when the weight summation is equal in weight with holding by, lifting thing, and left and right like this two elevator chamber weight also equate.At this moment starting right winch (1) again lifts by crane due height to the permutation train and starts, lift or the decline problem to solve train, because the southern train of going of train with the past relative direction in north, its weight is near equate or differ can be not too many, so it is the poor of two row train weight that the weight railway carriage is held in preparation, as it is few to prepare weight, it is also few that accumulation of energy comes and goes number of times, lifting is very rapidly convenient, the efficient of lifting is very high, because many intersections are parallel stable mobile with two elevator chambers about the assurance of coordination overhung construction cable wire, can not produce inclination by experiment, and overhung construction all has fixed pulley in the above, in each fixed pulley drg is housed, as (17,12) to guarantee steady safety.Another program is that drg, CD-ROM drive motor are housed in the fixed pulley, and winch does not carry out lifting work.

When accumulation of energy work was finished, when right elevator chamber rose to the end, all pins in the fastening pin socket insert as stretch out with automatically controlled or vapour control (14,12), so right elevator chamber were fixed in the above and carried out train and leave and enter work.Steel rope is easy

The damage part if transposing intersects and the coordination steel rope, just rises a plurality of hydraulic pressure lifting devices pressurizations in the hydraulic pressure lifting device base (38) and rises, and left elevator chamber loosens intersection and appositive construction steel rope and changes.The wire rope suspensioning after the transposing many be fixed on single-sheaved block on the elevator chamber as (8,34) on, hydraulic pressure lifting device is descended, left and right two elevator chamber steel ropes are tightened, and make every intersection and coordination overhung construction steel rope stressed evenly, and then every fixedly wire clips tighten as (9), intersection and coordination steel rope become most single fixing, even one just in case damage can not influence the overall situation yet, intersection and coordination steel rope are one when installing, be initiated with (10) end during wire rope handling, the end is (35).If steel rope oversize one not enough, need many joints, joint area should be placed on above the elevator chamber in the middle of the two adjacent pulleys so.Can carry out the trace of steel rope like this regulates.

When every fixedly wire clips all tightens, intersection and coordination overhung construction steel rope become single, and require length all the same, for this reason must be coordination steel rope fixed pulley as (19) design height than intersecting the fixed pulley height, higher by calculating, could guarantee that their length is all identical, in the lifting operation, every of the stress of rope rope all equates like this.

According to strength of material, the elongation of steel rope is calculated by following formula:

△L _N＝NL/EA

△ L _NThe elastic deformation [rice] that---by axle power N (N=P) causes

L------rope length [rice]

A------rope sectional area [rice ²]

N------axle power [newton]

E------modulus of elasticity [kilograms per centimeter ²]

After steel rope is selected, △ L _N, E, A be definite value, establishes S=△ L _N ^*E ^*A, then following formula can be simplified N=S/L.

Following formula can illustrate that suffered axial force of steel rope and rope length are inversely proportional to, and every rope rope bearing strength test equates that having only every rope rope (intersection coordination) equal in length is prerequisite, could guarantee safety like this in order to guarantee to be in operation.

The group logarithm of a winch left side and right pulley group reaches the size of at every turn holding weight placement amount, determine according to the pulling force index of left and right two winchs.

The present invention salvages the rivers Watership Down, and heavy ship has speed and reaches the characteristics that do not need big power machine soon.Said speed be soon since on the workboat and sea the continuous weight of accumulation flotation tank of operation, enough the flotation tank of floating weight is locked on the hoist point to the bottom under disposable then, can reduce repeatedly the work capacity in water-bed operation like this.In addition, do not need bigger weight-lifting equipment, can reduce investment outlay, salvage expenses is not high yet.Ship all adopts and floats heavy group to constructional device if salvage a sunken ship, and our ships and light boats early are equipped with prefabricated hoist point and float heavy group structure is rescued deposit as salvaging.Can accomplish secret salvaging fast, do not add workboat on the sea, floating heavy group transports in water structure and puts in place, fishing job is just floated heavy group to hook and excision work to structure, the use that the length group is right can accomplish that whole ship or ship present little state that floats, general submarine can traction, can transport in the underwater secret.

Utilization accumulation of energy lifting method is carried out crane lifting service overweight, the overlength object on the ground.Two elevator chambers are set by with the bit interleaved overhung construction, ensure long elevator chamber horizontal attitude upper and lower displacement, the load of packing into for a case is in addition held weight, and one case hook or be transported into weight overweight, overlength carries out crane lifting service when being equal in weight for two the casees.Can accomplish rapidly, safely, the purpose of reducing expenses.

   8. it is right to organize in pairs: after the shipwreck ship is salvaged rising, two little floating are sunk group to a chain they being connected in the middle of the water surface, again flotation tank is drawn in very bottom of ship, make two groups of flotation tanks ride the ships and light boats bottom, fix with Y shaped steel support, how many its sedimentation ball reservations will be seen concrete ships and light boats stable case and decide again.The effect of Y type support can make the ships and light boats down-shift of working center, and is long according to Y frame lower wall with what Y type supports, makes whole center of gravity drop to suitable stable point, to ensure safety.

   9. organize colligation: be exactly together, will on flotation tank, divide the twice colligation with honeybee shape hinge during colligation seven flotation tank colligations.To below the water surface, a bit carry out during colligation, its fallout is little single many balls of case fallout that floats, its fallout is designed to the steel ingot shape, and the rapid recycling use of this fallout small-sized lifting appliance easy to use can make seven flotation tank colligations receive on the hoist point of ships and light boats so together.

   10. group is loaded and transported in batch to structure: if very secret salvaging of the ship of our sinking returned just need carry out several 10 and floated heavy group and check the destination with submarine under water to installing, just several 10 are floated heavy group to being hooked on around the submarine lifting and travelling that to carry out resistance very big, speed is very slow, just in case running into emergency situation all breaks off relations at once, escape from the danger zone, float heavy group structure all is in little heavy state, secret sinks to the seabed when the situation is critical, use the seabed operation device more afterwards, carry out the hook transportation singly, after arriving shipwreck ship place, with the seabed operation device each being floated heavy group again salvages being hooked on the hoist point, at this moment require to have been had the lifting effect by hook, all flotation tank and shipwreck ship are little state that floats; At this moment can the hook shipwreck ship secret traction of operation submarine slowly runs to safety zone and salvages the work of surfacing again.
3. Three. accumulation of energy lifting method lifting ultralong overweight object:

   The present invention is provided with many Suo Lianhe overhung construction device, two elevator chambers are arranged, one case hook or be transported into by hoisting heavy, one case configuration and be transported into one by one and carry on a shoulder pole mass in addition, when being equal in weight for two the casees, other carries on a shoulder pole the weight sludge box and descends, be required that the whole huge weight that lifts by crane rises to the demand height, to reach the lifting purpose.Many Suo Lianhe suspention transformational structure devices are by the many cable suspensions device that intersects and coordination rope rope is formed, intersect and guarantee that with coordination rope rope structure the displacement up or down of elevator chamber horizontality does not produce inclination, intersection has single-sheaved block to be connected with coordination rope rope at the elevator chamber place and has cable clamp stuck after adjustment, ensure that every rope rope is stressed evenly, two elevator chambers can be handled two elevator chambers with two winchs and move up and down.Train or weight that one elevator chamber is packed into and will be lifted by crane, another elevator chamber is transported into one by one with discrete load storage weight (trifle, a trifle compartment) in addition, and the weight of train that will sling when starting winch and other carry on a shoulder pole the configuration of storage weight weight and equate.A power loss is in friction with above the rope rope resistance to deformation.All wheels arrangements drgs above the overhung construction, another program are each wheels arrangements CD-ROM drive motor and drg above the overhung construction, omit winch.
