Abstract
The invention relates to a Taiping drum ship box automatic horizontal slanted-slot type ship lifter which belongs to the technical field of hoisting and conveying machinery. The lifter can surmount large dams constructed for large rivers, and makes sure the ship go smoothly without obstacles. In the lifter, a Taiping drum is used to bear, so that the ship box is balanced automatically. The liftercompletes the traction task by balancing weigh and starting and coordinating a motor, and the interesting tension weight also plays a key role. A slanted-slot is taken as the running channel of the ship box, and the height of the ship box from the ground is a constant value in the whole transfer process. Two sets of operation modes are set to ensure safety; the ship box self balancing principles of the two sets of operation modes are the same, which ensures technical continuity. In particular that a circular arc tooth-shape wheel track system not only provides large-burden capacity, but also ensures that the ship lifter is balanced when stopping at any place of the track. To ensure the stability of the ship box as a ship lock when the ship goes through the ship box, a splayed brake disk set is in particular arranged on the ship box, and the brake disk set can be also used in operation. See the manual for details.
Description
One, technical field:
The field is the handling machinery field under the peaceful drum ship case automatic horizontal oblique slot type ship lift, is the machinery of extraordinary lifting transportation associating.
Two, background technology:
On the type of present ship lift, four kinds of existing lift-type vertical ship lift, balance weight type vertical ship lift, inclined ship lifts, float-type ship lifts etc., their characteristics are as follows:
Lift-type vertical ship lift lifting weight is little, power consumption is big, can cross over dam.
Balance weight type vertical ship lift and inclined ship lifts load-carrying are big, energy-conservation, can not cross over dam, require range of stage little, stay the interface door opening below crest elevation, have destroyed the globality of dam.
The float-type ship lift requires range of stage little, and the upstream and downstream drop is little, is applicable to artificial canal.
More than explanation, these several ship lifts all can not possess simultaneously: lifting weight greatly, do not leave a door unlocked the hole, adapt to actual requirements such as any SEA LEVEL VARIATION and the big drop of upstream and downstream.What can satisfy these requirements is exactly the following peace drum ship case automatic horizontal oblique slot type ship lift that will introduce.
Three, summary of the invention:
(1), the technical problem of Xie Jueing
What as previously mentioned, the present invention attempted to solve is: requirements such as big heavy duty, any SEA LEVEL VARIATION of adaptation and the big drop of upstream and downstream, leap dam, energy-saving safe.
Cause the actual conditions that the navigation of rivers dam needs ship lift that are based on of invention motivation.
(2) technical scheme:
Automatic horizontal oblique slot type ship lift comprises boat supporting case, puies forward fortune main frame, balance weight, tension weight, sloping top towing bracket, wheel track, sure brake system and signal system; Boat supporting case combines formation ship lift complete machine with carrying the fortune main frame, and other parts cooperate complete machine work; It is characterized in that: carry the fortune main frame by load-bearing drum barrel, bearing tile system, pylon and vehicle frame main beam, track cable are formed, pylon is provided with axis of traction, and the load-bearing drum barrel is supported by pylon, and pylon is supported by vehicle frame main beam, the rail wheel that contacts with wheel track is arranged on the vehicle frame main beam, bearing tile system and load-bearing drum barrel form and are rotationally connected, and the bearing tile system is connected with track cable, and track cable connects boat supporting case, boat supporting case is provided with the case ear, and this case ear places the safe beam part of pylon; Wheel track is connected and composed by domatic straightway and sloping top arc, is provided with the boat supporting case operation skewed slot that is lower than track between the wheel track.
Be described in further detail and comprise following 7 aspects:
1, principle summary: shown in Figure 5 referring to the 1st page in accompanying drawing.
The peaceful drum of the present invention ship case automatic horizontal oblique slot type ship lift principle is very simple, promptly rouse the cylinder of sample with a picture, wire rope strides across cylinder, fasten on by two fulcrums of handling weight at two ends, pushing away cylinder then along promptly fixed orbital motion, just in a groove that is lower than track, moved along with the motion of cylinder by the handling weight.This groove is a conveying trough, and for ship lift, this groove tilts, and therefore claims skewed slot.Adopt it that the main frame height is reduced, machine gravity reduces, and can also provide support for the boat supporting case braking.
If load onto special traveling mechanism at the two ends of cylinder, then cylinder only is responsible for holding the weight that passes object just as a beam.When the timing of track grade weighing apparatus, the lifted weight thing will undisturbedly move with cylinder.
Because ship lift will be crossed dam crest, so the domatic inclined plane of dam crest employing arc orbit connection upstream and downstream, inclined plane is connected with arc orbit is tangent.Obviously, the gradient of each point is all inequality on the arc orbit, but all less than the gradient of inclined plane.Be whole service track grade maximum be oblique orbit, be a steady state value, this will help track to extend along domatic straight line, to adapt to the water level of any requirement.
When this machine moves to the arc orbit that track grade changes, under the effect of own wt, automatically be adjusted into the position that makes object keep original equilibrium state along the tangential slip of cylinder surface by wire rope by the handling object.If boat supporting case is by handling, boat supporting case bottom surface level all the time then, boat supporting case automatic horizontal principle that Here it is.
Because this machine has adopted the bulging short and thick cylinder load-carrying of picture, the supporting capacity reasoning of being not difficult greatly is for this reason with cylinder called after load-bearing drum barrel.
Because this machine is to orbit, need only the track crossings dam that is provided with and extend to design water level, just can adapt to any SEA LEVEL VARIATION, aqueduct is established in the hole that need not to leave a door unlocked below crest elevation.
Owing on prograde orbit, move, and track cable only have along the very little tangential displacement in drum barrel surface, so safety is easy to guarantee the reasoning of being not difficult not often around song.
And this point exactly vertical ship lift be beyond one's reach.
Because it is main adopting balance weight, be aided with motor and coordinate the operation of this machine of pulling, shown in Figure 5 as the 1st page in accompanying drawing, so that this machine is compared with the lift-type vertical ship lift is very energy-conservation.The operation raceway gradient that balancing in situ is heavy can also accomplish that balance weight is also lighter than complete machine like this greater than carrying fortune main frame track grade.
Because the center of gravity of the main load boat supporting case of this machine is lower than track, the center of gravity of complete machine is also very low, so its stability is fine, safety guarantees easily.
More than the characteristics of five aspects, solved the technical problem that proposes previously, principle is simple and clear, comprehensive must being called: " peaceful drum ship case automatic horizontal oblique slot type ship lift." this machine is formed that boat supporting case is arranged, put forward fortune main frame, balance movement system, safety and brakes, signal system five major parts, be described respectively below.
2, boat supporting case:
Boat supporting case is made up of four parts such as casing, lifting beam column system, casing brakes, case ears, as the 1st page of Fig. 4 of accompanying drawing and Fig. 16 shown in.
(1) casing 11:
Casing is the container that loaded the dam ship, and entrance gate is reserved at its two ends, is convenient to the ship turnover.
(2) lifting beam column system:
The lifting beam column system is made up of four beams of four lifting posts and capital.Spandrel girder group when wherein left and right beam is formed normal the operation is fastened the wire rope that strides across the load-bearing drum barrel thereon.Spandrel girder group when front and rear beam is formed safe operation cooperates the fixed case gudgeon by the locking beam under the beam, and the moving axially of restrictive axes rotated and then can unrestrictedly more be helped mechanical sensitivity.The other end cover top box ear body of case gudgeon, case ear body rides on the vehicle frame safety beam, and when normally moving, the case ear swings with boat supporting case, and like an indicator, when ship lift arrived the track summit, it should be in safety beam middle.When normal operational system breaks down, enter the safe operation state, case ear body just is supported on the safe beam, and the case trunuion bearing passes whole loads of boat supporting case, guarantees that as a pin boat supporting case can not fall in ground.This moment, promptly the water in the removal boat supporting case deducted corresponding balance weight (balance weight is a separate assembling), the ship conditions permit that prerequisite is delivered simultaneously with weight reduction.
(3) casing brakes:
The casing brakes is to be installed on two groups of brake puck groups of lining up " splayed " that are lower than the orbit top surface of the beam on the casing, and shown among Fig. 4 12, " Eight characters " gradient is with domatic consistent.Can be locked in boat supporting case the cell wall on both sides when being used to stop reposefully, be convenient to ship and pass in and out boat supporting case stably.Its power set with hydraulic drive for well.Upstream group is used in the upstream during use, and downstream group is used in the downstream.In running, also can cooperate and put forward fortune main frame brakes whole ship lift is rested on any orbital position.
(4) the case ear 6:
The case ear is made up of case gudgeon and case ear body.One end of axle is fixed by spandrel girder before and after the boat supporting case and locking beam, and the other end is enclosed within on the case ear body of shape picture " circle is precious " or canoe sample.Can freely rotate between case ear body and the axle, like an indicator, when ship lift arrived the track summit, it was in the middle.Reach as described above, under security operating mode, boat supporting case can be under action of gravity, by the rotation realization automatic horizontal of case gudgeon.In order to obtain enough big supporting force, be combined into good between case ear body and the axle with sliding bearing.In addition, be in the centre position of safe beam all the time in order to make the case ear under security operating mode, be provided with a cover hydraulic pressure centering means in the case ear body skirt member, start its case ear in can making partially and get back to safe beam centre position, safe top surface of the beam should be brushed with lubrication oil.
3, carry the fortune main frame: shown in Figure 1 as the 1st page in accompanying drawing.
Carrying the fortune main frame is the transhipment machinery of ship lift, and carrying the fortune main frame has normal operation and two kinds of system models of safe operation, and its vehicle frame primary and secondary beam and running trolley are as follows in the face theme.
Normal operational system pattern is made up of three parts such as load-bearing drum barrel 1, spandrel girder column system, bearing tile systems 2.
The safe operation system pattern is made up of case ear 6 and safe beam column system.
More than remove the case ear and partly be described at boat supporting case, other division is as follows:
(1) the load-bearing drum barrel 1:
The load-bearing drum barrel is one of the main load-bearing of normal operating condition and automatic horizontal member, and the load-bearing drum barrel bears boat supporting case all wt and the drum barrel deadweight that bearing tile transmits.Be in operation when the gradient changes, drum barrel rotates around arc orbit with vehicle frame, and bearing tile is tangential the moving to realize the boat supporting case automatic horizontal on its surface then, requires to have enough rigidity for this reason.No matter therefore drum barrel will be a critical component on stressed or horizontal principle, the drum barrel diameter is big more, and rigidity is big more, helps needle bearing layout in the bearing tile more, and tile fragment rolls on drum barrel, and friction can be very little, and the boat supporting case automatic horizontal is just sensitive.
(2) spandrel girder column system:
Beam under the normal operating condition is the supporting drum barrel, and two ends lean against the beam on the capital.Capital is configured to by two pylons that are barricaded as " herringbone ", as Fig. 14 shown in.Such coupled column framework power transmission is more even, calculates easy.
Beam under the safe operation state is the safe beam of supported box ear body, swings when the case ear normally moves for adapting to, and top surface of the beam is designed to arc surface, and case ear body bottom surface also is the arc surface with diameter simultaneously.Can slide relatively during two faces contacts when guaranteeing safe operation, be coated with lubrication oil at the safety top surface of the beam.Safe beam is supported at both ends in the capital of small-sized " herringbone " pylon structure, as Fig. 15 shown in.So " herringbone " pylon structure under two kinds of operational modes synthesizes four " many fonts " post architecture of whole vehicle frame.In addition, stressed more reasonable in order to make whole vehicle frame, hold together with a light section beam below " many fonts " post architecture.
Do not work under normal operating condition because of the safety beam in addition, can play coordinative role, thus the axis of traction 8 of this machine is arranged at safe beam center, to make full use of this member.Certainly, axis of traction can also be fixed on the vehicle frame main beam.
(3) bearing tile system 2:
For the track cable of avoiding hanging boat supporting case directly contacts with the drum barrel surface, reduce wearing and tearing and friction, the bearing tile system is set between wire rope and drum barrel.Arrange the needle roller of sufficient amount in the tile fragment, reduce contact pressure as far as possible, make the tile fragment motion flexibly.Rotate ineffectively for the tile fragment that prevents lack of lubrication or needle roller breakage to cause is attached to drum barrel surface, setting tile fragment just is the ultimate range of tile fragment rolling with the gap of linking beam 25 end faces of the parallel equal-height position of drum barrel axis.Adhere to when motionless when tile fragment takes place like this, the support of linking beam end face can allow it force to rotate, and corresponding warning device is set so that in time find this problem.
4, balance movement system:
The balance movement system is made up of vehicle frame primary and secondary beam, wheel rail system, balance traction system, four parts of boat supporting case run channel.
(1) vehicle frame primary and secondary girder system system:
As 7 being depicted as vehicle frame main beam among Fig. 1 of the 1st page in accompanying drawing, to fail to draw because of the secondary beam under the proportionate relationship girder and the running trolley under the secondary beam, meaning loses self-evident.
Vehicle frame primary and secondary girder system system has constituted with aforementioned spandrel girder column system, load-bearing drum barrel carries fortune main frame skeleton, because of the function narration needs to separate explanation.
Vehicle frame primary and secondary girder system system reasonably carries out the distribution of load in conjunction with top spandrel girder column system, reduces the wheel load value of running trolley as far as possible.Each running trolley combines three wheels in this routine machinery, and running trolley of the every end of secondary beam, girder are divided into corresponding 14 secondary beams of 14 fulcrums, and both sides amount to 28 secondary beams.Between secondary beam and running trolley, establish the shock-absorbing spring steel plate, steel plate curved arc epirelief.The steel plate two ends act on wheel interval on the craneway.
(2) wheel rail system:
This machine track adopts inclined plane and arc orbit combination.On the length of upstream and downstream is domatic, all adopt the inclined plane of the identical gradient, only just adopt the arc orbit of suitable radius to connect in upstream and downstream inclined plane junction, sloping top.Pure arc orbit is compared in the combination of this oblique orbit and arc orbit can be shorter under the control of identical maximum gradient, and adapt to water level and change arbitrarily, and oblique orbit can extend downwardly into lower water level always.
Wheel rail system is one of big heavily loaded ship lift key of success, because the primary condition that this machine is considered is 3000 tons and above ship lift, its wheel load is all very big.Ship lift below 3000 tons is then as long as change wheel thickness or the size and the respective track gradient.Because of this machine mainly is to move on inclined plane, the influence that overcomes sliding force is also very important again.Therefore, the wheel that this machine adopts is the band edges of a wing, steel circle-arc tooth wheel both sides, and is shown in Figure 6 as the 2nd page in accompanying drawing, rides on the track and rolls, and orbital plane is the recessed track of arc surface that adapts to it.Adopt such wheel rail system, no matter ship lift stays in any position of track, all will have only the downward normal pressure of vertical between wheel and the orbital plane, and not have sliding force, sliding force comes balance by the frictional force between track bottom surface and the rail beam, and track glides and is easy to just overcome like this.The effect that this machinery will reach is: even the extreme case of haulage cable 24 fractures or axis of traction 8 fractures takes place, the ship lift main frame also can rely on brakes to be stopped can to fall in the water in orbit and not.
(3) balance traction system
This machine travel system is by balance weight system and cross the top actuating motor trailer system of coordinating to hold concurrently and form.Main tractive force is from balance weight 13, and is shown in Figure 5 as the 1st page in accompanying drawing, is arranged at by the main frame track of domatic skewed slot both sides, downstream.The motor trailer system only is used for cooperating and starting, and is installed on the motor on the running trolley, is connected with wheel by speed changer.
When being set, balance weight should note three aspect factors:
At first, utilize axis of traction 8 to determine the gradient of balance weight raceway, make it to reduce the weight of balance weight like this greater than the gradient of carrying fortune main frame track to the discrepancy in elevation between the skewed slot bottom surface.Operation road face is made up of the roller bearing 22 of guiding braking orbit 23 and domatic tiling, as Fig. 9 of the 2nd page in accompanying drawing and shown in Figure 10.For safe and reliable, adopt two guide rails, lay roller bearing between two tracks, when normally moving, balance weight lies in and is in running status immediately on the roller bearing, makes an immediate response as long as motor one starts balance weight.When security crisis takes place, during as the traction steel wire fracture of rope, balance weight must glide at a high speed, and the speed limit locking device is set on balance weight for this reason, makes it guarantee the balance weight safe operation taking place to lock the guiding braking orbit when gliding at a high speed.Depart from traffic direction in order to correct balance weight, with the side place that the guiding braking orbit may come in contact the rolling contact device is installed, when balance weight takes place by small departing from, obtain immediately rolling and revise in balance weight.
Secondly, it is locked to stop on the arc orbit summit when avoiding ship lift to cross the top, forms a dead balance, and haulage cable 24 should stay one section slack lengths.Hang for loose haulage cable is piled up, mechanism's tensioning wire rope of being made up of movable pulley and tension weight 14 is set on domatic, pull it towing bracket 15 in the upstream.Shown in Figure 5 as the 1st page in accompanying drawing.
Once more, can not be too high the towing bracket setting at place, track summit, the height that ship lift is crossed top last axis of traction 8 on opportunity should be lower than, otherwise axis of traction will be blocked, ship lift can not be crossed the top.Should make support integral body shorter under the possible situation, stress performance and stability can be better like this, and haulage cable conversion direction time space was bigger when ship lift was crossed the top, and transition is steady.In addition because of can not intervisibility between towing bracket top fixed pulley and the slope end minimum point, haulage cable can contact to earth, so below the haulage cable on top, slope, guiding fixed pulley and support 16 should be set, be divided into two-layer, top layer is being chosen the haulage cable that connects the ship lift host side, lower floor's downstream direction is being chosen the haulage cable that connects the balance weight end, and updrift side is being chosen the wire rope that connects tension weight, and quantity is determined by concrete condition.
In addition, because balance weight is the same with ship lift very heavy, speed and ship lift are synchronous, and it will stop suddenly under the high-speed cruising state when ship lift is crossed the top, can produce very big impact force, and kinetic energy rejection is also very big.For this reason, at first balance weight is divided into plurality of small blocks after, form whole with fastener.Each fritter front end is the plane, and the bigger spring pad of stroke is loaded onto in the rear end, drops into one by one in order to energy dissipating with when up.Two forequarters are equipped with and allow to connect the fastener that pin moves forward and backward, and the rear portion, both sides is stretched out two and connected pin, and former and later two fritters just can realize that big gap connects like this.The tension weight of upstream on domatic should be too not little besides, and suitable size can absorb part energy.The 3rd, balance weight anchor point place, the sloping end is provided with the large-scale elastic support of compound high stroke in the downstream, is beneficial to the heavy kinetic energy of absorption equilibrium, makes the balance weight operation stop all very steady.
Cross the top and coordinate the setting of actuating motor of holding concurrently:
Actuating motor is installed on the running trolley, be connected with wheel by speed changer, its setting will be coordinated with the balance heavy phase, detailed process is: energising starts main frame after predetermined speed, balance weight inertia downslide traction engine arrives a certain grade point of arc orbit, balance weight quits work, and this moment, ship lift relied on the tractive force of motor to arrive the track summit.When dropping to the point identical of counter-slope face then with the just domatic grade point gradient in front, by the deadweight sliding force of ship lift add the tractive force of motor make ship lift in tow balance weight stop after going downwards to predetermined water level, balance weight rose and obtained gravitional force this moment.So just finished the process of once transporting ship.
Obviously, the definite of former and later two grade point gradients not only influences ship lift power of motor size, also influences the length that non-preformed wire rope is pulled out in the domatic tension weight in upstream.The gradient is too little, and ship lift is close to the top, and domatic upward the ship lift sliding force is little, and the installed power that requires when descending is big, and the slack lengths that wire rope is drawn out is little; The gradient is too big, and domatic upward the ship lift sliding force is big, and the installed power of the up requirement of main frame is big, and the slack lengths that wire rope is drawn out is big.
Preferred plan is that the point of getting the inclined plane gradient that equals half is deactivated as balance weight and tension weight and whole motors starting points of devoting oneself to work.Because the whole power of motor sizes of self-propelled ship lift depend on the size of the inclined plane gradient, so the installed power of this machine can be got self-propelled ship lift power on the oblique orbit half simply, then only cross in the use and just flat-outly on the tip circle arc track devote oneself to work in short-term.
5, sure brake system
Sure brake system comprises security system and brakes.
(1) security system
This machine of analysis security crisis is most possible to occur and endangers maximum link have two:
The one, fracture appears in track cable;
The 2nd, haulage cable or axis of traction fracture appear in operational system.
It is serious that other security crisis all is not so good as this two aspects harm, can find to get rid of by at ordinary times safety inspection and regular maintenance.
The solution that the first aspect track cable may rupture has:
1. regularly carry out safety inspection, change damaged wire rope.
2. start this machine safe operation system pattern, its course of work is: when accident takes place, hydraulic pressure centering means in the starting box ear, ship lift withdraws from normal operation mode then, whole loads of boat supporting case automatically or the people be transferred to two huge case ears, pass to the safe beam of supported box ear by the case ear, so just realized the pattern conversion, the assurance ship lift can safe operation be got back to the maintenance point, even can promptly move a period of time under this state.In order in time to pinpoint the problems, when the case earpiece is subjected to gravity, the corresponding synchronous warning device is set, so just know that normal operation mode has problem should enable security operating mode.
The solution of traction steel wire fracture of rope that second aspect may occur or axis of traction fracture has:
1. connect haulage cable and axis of traction with the bright and clean lubricated collar of inner surface, except that making regular check on, the periodic replacement axis of traction is particularly important, because axis of traction may produce fatigue failure, is difficult for finding.
2. regularly carry out safety inspection, change damaged wire rope.
3. two cover haulage cables are set, keep the main stay cord of title of normal operation, guarantee the secondary stay cord of title of safe operation.By regulating, allow main stay cord than the short small scale of secondary stay cord, this small scale just is the stretch value of main stay cord under load action.Like this, when normal operation, main stay cord bears whole pulling force, and secondary stay cord is only followed operation.When main stay cord occurred elongating or ruptures, secondary stay cord put into operation immediately.For the sake of security, when secondary stay cord puts into operation, synchronous warning device is set so that in time find this problem.
(2) brakes
There are two covers in the moving system of this mechanism, and a cover is the casing brakes that the front is talked about when saying boat supporting case, adopts hydraulic control to help obtaining bigger brake force.
Second cover is exactly to put forward fortune main frame brakes, and the handling machinery brakes of it and other is the same, can be installed in brake on the turning cylinder of wheel or motor, and assurance main frame whereabouts freely.Two cover systems cooperate during use, and are similar just as the service brake and the parking brake of automobile, and it is also happy as driveing a car to drive ship lift.
6, power supply and signal system
(1) electric power system
Setting up according to motor type and the power selected for use of electric power system determined.Domatic in the upstream, because range of stage is very big, power line must be maked somebody a mere figurehead enough height, domaticly in the downstream can arrange attractive in appearancely as far as possible.
(2) signal system
Open and close chamber door in order to coordinate main frame whereabouts and boat supporting case, conveniently transport ship, guarantee the transmission promptly and accurately of security alarm signal, a cover signal system need be set.By means of modern electronic technology and Computer Multimedia Technology, as long as various signal transmission promptly and accurately, the operate services personnel of this machine can significantly reduce, and optimize manpower.
7, complete machine operation explanation
Shown in Figure 5 as the 1st page in accompanying drawing, after pleasure-boat only entered boat supporting case 18 instantly, ship lift main frame 17 began to start, and balance weight 13 moves downward, and rises by haulage cable 24 traction ship lifts.When balance weight ran to minimum point, the motor on the ship lift was all devoted oneself to work, and the traction ship lift is crossed the top, and tension weight 14 this moment is pulled out towing bracket 15 to loose haulage cable by movable pulley.After ship lift is crossed the summit, continue upstream domatic decline, the haulage cable that is drawn out discharges gradually and contacts with the fixed pulley of updrift side, when discharging, the haulage cable of pulling out finishes, wire rope is tauted, balance weight is subjected to the traction of ship lift and begins to rise, and ship lift then continues to stop after dropping to predetermined water level along the upstream is domatic, and this moment, the rising of balance weight also stopped.The ship that is handled upside down rolls boat supporting case away from, finishes from swimming over to the carrying of upstream down.The ship that the upstream is come begins to enter boat supporting case, is from upstream to the carrying in downstream, and running and said process are similar.
Ironically, in the whole service process of ship lift, motor is flat-out the putting into operation of the ability of the part rail section on arc orbit only, held by the driver, on inclined plane, then only need the very little operation that statically balanced power just can be kept this machine of breaking, so this machine is energy-conservation machine.Haulage cable is then taken the conversion direction between the towing bracket fixed pulley that turns back over domatic of upstream and downstream, and length only needs the length of downstream on domatic to add the preceding paragraph slack lengths, so the range ability of balance weight is less than the boat supporting case range ability.
In addition, boat supporting case moves in a groove that is lower than track all the time, and this does not have at ship lift in the past.As long as allow boat supporting case press close to the bottom land operation as much as possible, even boat supporting case falls under the extreme case, loss can be very not big yet.This machine overcomes this safety problem with two cover operational modes still more.
(3) effect analysis:
Below this machine is analyzed in the effect aspect technology and economic two.
1, technique effect:
Contrast existing ship lift technology, just can conspicuously find out the technique effect of this machine.
1. compare with the lift-type vertical ship lift:
The advantage of lift-type vertical ship lift is carried the fortune weight and is crossed over and can drop to the water level of carrying before the fortune behind the dam, and shortcoming is that to put forward fortune weight limited, and power consumption is big, along with the increase safety problem of putting forward fortune weight is outstanding.Therefore do not carry at present the very big ship lift of fortune weight.
This machine is except that the advantage with lift-type vertical ship lift, also its shortcoming is overcome one by one and become advantage, unique difference is that the shared space of this machine is bigger than vertical ship lift, and this machine has brought the gradual digestion of hoisting depth exactly with the space, successfully solve heavy and safety problem.
2., compare with the balance weight type vertical ship lift:
Balance weight type vertical ship lift advantage is energy-conservation, and lifting weight is bigger, and it is little to take up room.Shortcoming is that hoisting depth is little, and incompatible bigger range of stage can not be bypassed the dam site.
This machine is except that the advantage with it is energy-conservation, and lifting weight can be than its big and safety, because this machine load-bearing steel rope and haulage cable separate, track cable is short and static.This machine still overcomes its shortcoming one by one, becomes advantage.Do not turn over dam only, do not fall less than water level.
3., compare with the float-type ship lift:
Float-type ship lift transhipment weight decide with the size of floating drum, takes up an area of less but is subjected to the river course condition restriction, economizes on electricity and wastes water.Fatal shortcoming is that height of dam can not be too high, and range of stage can not be too big, can not bypass the dam site.Be not difficult to find out that thus these facility have absolute predominance.
4., compare with inclined ship lifts:
Here inclined ship lifts are divided into height track crossings dam crest formula inclined ship lifts and the domatic formula inclined ship lifts in downstream.
Height track crossings dam crest formula inclined ship lifts such as Danjiangkou inclined ship lifts are that with the difference of this machine maximum it " withstands on boat supporting case on the head ", this machine be boat supporting case when spending blue " carrying in hand ", this machine of security and stability advantage many; The former just replaces at dam crest by track, and this machine track is parallel arranged side by side, and this machine of running stability is dominant! The bearing capacity of limited wheel under the fulcrum of boat supporting case two ends is depended in its load-carrying, and this machine then provides load-bearing by a lot of groups of wheels under a lot of down individual fulcrums of vehicle frame main beam, and vehicle frame main beam is long more, and the wheel that can install is just many more, and bearing capacity is excellent greatly.
Downstream domatic formula inclined ship lifts advantage is to realize heavy, because its boat supporting case directly is bearing in the domatic operation of going up.But can not bypass the dam site, can not adapt to bigger SEA LEVEL VARIATION, therefore can not mention in the same breath with this machine.
Even if 5. compare with ship lock:
Ship lock is that an ancient ship is crossed the dam instrument, and its advantage is that technical simply being easy to built, and shortcoming is that water consumption, consuming time, economic progression are few, and this machine by comparison, and is technical brief and concise equally, just never is familiar with before.It is unrestricted in theory that this machine is crossed over height of dam, and energy-and time-economizing also leans to the big elevator that can also climb over the top, slope on domatic because this machine is exactly one one, and speed is fast, and the time just economizes.Bold inference: two-stage and above ship lock do not have advantage to this machine.Therefore, the key water control project on the great rivers, when height of dam surpassed one-level ship lock economic height, the anthology machine realized that navigation is fully desirable.
At last, on purposes, this machine can also be used for the maintenance of the vessel industry except finishing the rising the ship function of own job.Imagine, the ship that needs repairing in the water is pulled into boat supporting case after, be transported to the land and keep in repair, than whether much betterly in water, feeling? just seldom having thought of other.
2, economic effect:
From mechanical manufacture view, because more outstanding than existing ship lift type on this machine technology, its manufacturing will indicate that this field adds the newcomer again, will bring billowing financial resources.
From the water transport aspect, reach as described above, the motivation of developing this machine is based on 3000 tonnes of demands that ship lift is such, and what will solve such as the ship lift in Three Gorges is exactly water transport problem.Along with building up of Three Gorges Dam, the Changjiang river golden waterway is under suspicion, so people just improve the number that goes to calculate hours underway from Channel Condition the benefit of construction dam to shipping is described, this also is justifiable.Yet, fundamentally solving ship and cross the dam problem, Yangtze River shipping just is not the problem that Bao Tong maybe can lead to, but barrier free accessibility.Have only the realization barrier free accessibility, the construction of dam is just more flawless, and Yangtze River waterway becomes the emerald navigation channel thus.Since be accessible, just should be the steamer of maximum tonnage when crossing the dam with do not build before the dam very nearly the same.Because the advantage of this machine on principle if a ton single-wheel can be passed through in the navigation channel, Chuanjiang River, just can be built a corresponding ton ship lift.As for the time of passing through, also mention the front, the big elevator that this machine is equivalent to lean on domatic and can bypasses the dam site, be again rolling-operation, speed is per hour no problem at last by 20 kilometers, and establishing orbit the longest is 5 kilometers, once cross the dam and only need 15 minutes, add about 10 minutes of turnover ship case, always spend 25 minutes dam time, more about the same than not building before the dam by this section navigation channel.This rational illustration has represented this machine in the potentiality of improving aspect the Channel Condition, makes and builds dam and the unimpeded no longer contradiction of shipping, and the economic effect of bringing is so that social effect is infusive.
The effect of comprehensive technology economy two aspects illustrates that all these facility have huge vitality.Protection develop and will help the superiority development of China in this field, will make the large, medium and small river of China can both use up the profit of its shipping to greatest extent, allow plateau, valley, the Plain is molten by the river connection is one.
