Specific embodiment

Embodiment one:

The present embodiment is a kind of floating body crawler type ship lift, as shown in Figs. 1-5.The present embodiment includes: at least two to pass through vehicle frame The buoyancy tank 1 of connection, the buoyancy tank are equipped with crawler type walking mechanism 2, and the vehicle frame between two buoyancy tanks is equipped with energy Enough make the supporting table 3 of ship holding level, the supporting table is the arc-shaped rail that the low both ends at least two centres tilt, institute The ship reception chamber 4 of carrying vessel is run on the arc-shaped rail stated, the ship reception chamber bottom is equipped with multiple tight with arc-shaped rail Touch the runner 5 of touching.

Ship lift described in the present embodiment is primarily directed to use two point in small tonnage (80t or less) ship transport 6(Fig. 1 Scribing line indicate), operation ramp should be less than 1:10, can downstream shipping carry ship, with substitute bypass the dam site land transportation truck it is (existing Truck dead weight be 40t).

The main member of floating body crawler type ship lift: there are two equidistant float chambers, in the more crossbeams in the bottom of float chamber It penetrates two float chambers to be welded and fixed, is in addition to this also soldered to few twice door shape angle by top in the side on two float chamber opposites Gooseneck, for reinforcing the connection at the top of two float chambers, as shown in Figure 1,3.Crossbeam and door shape angle steel crossbeams constitute vehicle frame.

Float chamber has hung up caterpillar chain, and the transverse direction on caterpillar chain is equidistant to secure many crawler belt laths, the hole of caterpillar chain The tooth engagement of mouth and crawler belt gear makes crawler belt slats turn and ground face contact generate frictional force, ship lift is pushed to walk.In crawler belt The coaxial intermediate crawler belt gear of gear also hangs up caterpillar chain and is followed by rotation, it plays the role of supporting creeper tread.

The core of ship lift includes the ship reception chamber of three face barricade one side openings (ship inlet and outlet), ship reception chamber lower part At least two rows of idler wheels of setting.Idler wheel is mounted on supporting leg different in size, and supporting leg is welded on compartment by ship.

The length of supporting leg is arranged according to the Curvature varying of arc-shaped rail.The supporting leg at position is longer among compartment by ship, front and back Leg length it is shorter, make all idler wheel and arc orbit intimate surface contact, keep the ship weight in compartment and case by ship equal Even is distributed on arc-shaped rail by idler wheel.When ship lift climbing or descending, ship reception chamber is under the effect of gravity in circular arc It is rolled on shape track, remains horizontality, as shown in Figure 2.

Two arc-shaped rails are fixedly arranged between two float chambers on a plurality of crossbeam (vehicle frame) intermediate region, arc-shaped rail Both ends are equipped with the gear bank with rubber pad, to prevent ship reception chamber wheel from overstepping the limit.

The bottom plate in compartment and three face baffles can be formed using strip welded steel in length and breadth by ship, with the weight of carrying vessel Amount, but the discrepancy that water can be made not stop is gone by ship compartment.

Cable loop, the peace of ship lift ship in climb and fall operational process are installed in the upper limb of three face barricade of ship reception chamber Entirely.

If compartment is welded using steel plate by ship, what is be spaced in ship reception chamber base plate center line is opened there are four square hole and river water Connection, enables ship smoothly to pass in and out ship reception chamber, and the ship of load-carrying does not increase the weight of ship reception chamber in water.At ship reception chamber bottom The two sides of plate square hole spread rubber pad (or being replaced with old tire), and hull jolts when can reduce ship lift climb and fall.

In the rear wall of ship reception chamber, driver's cabin is set.The control system of general caterpillar is set in driver's cabin, to control The operation of ship lift processed.

The dynamical system of ship lift can be using the motor of power battery driving.Each when being driven using power battery The motor that each symmetrical installation in the both ends of float chamber has small diameter gear drives for driving the crawler belt gear of side major diameter Lath on caterpillar chain moves on the ground or in water, and ship lift is made to advance at a slow speed.Ship lift is not provided with the electromechanical dress of turning It sets, but uses for the national games turn of four motors of a float chamber, the first two motor of another float chamber has a power failure or four motors all stop What the method for electricity was realized.

Ship is picked since ship lift will navigate by water in reservoir and river, it is impossible to it is former using the electricity of overhead wire, and because Two rail occupy very large space in ship lift, and diesel engine and hydraulic pump dynamical system are placed in no place, therefore can only Using high power DC electric machine, use power battery as power supply, power battery box is mounted on ship reception chamber front and back both ends wheel Side, battery does not need to unload down when charging, and ship lift directly reaches at staith charger room, is charged with bracing wire bolt.

Fig. 4 is after ship enters ship booster supporting compartment in reservoir, and then ship lift turns round upstream ramp road and creeps；Figure 5 be that ship lift travels on downstream ramp road, and subsequently into river, ship is driven out to from ship reception chamber into river.Due to arc-shaped The effect of track can guarantee that safety crosses dam regardless of ship lift climbing or descending, ship reception chamber can keep horizontality.

Ship lift is in reservoir or in river, it is desirable that the drinking water of ship lift float chamber cannot be below 5m deeply, make in ship reception chamber The depth of water reach 1.6m, while the ship extreme draft of load-carrying is deep no more than 1.25m, and otherwise ship not can enter hold in water Ship compartment.No matter ship lift climbed from reservoir and dam or climbed dam from river, or navigated by water in water, advanced in ship lift Cheng is always to maintain the opening of ship reception chamber in preceding, driver's cabin rear.

It can also be seen that ship lift is in upward slope or descending process from Fig. 4,5, ship reception chamber in a balanced condition, thereafter Wheel and front-wheel all keep some distances with the block of rail respectively.Due to being equipped with the protective layer of resilient rubbber cushion in block, when Rear-wheel or front-wheel will not cause ship to vibrate when touching with block.From Fig. 4,5 it is also seen that in ship lift uphill, downhill process, point The bottom plate not at ship reception chamber opening bottom plate and by ship compartment rear wall, it is all close apart from rail surface, there is a possibility that mutual impaction, In order to avoid colliding, the special bottom plate by both ends before and after ship reception chamber is cut down inwards goes a part, sees Fig. 1,2,4,5.

Embodiment eight:

The present embodiment is that a kind of ship using above-mentioned floating body crawler type ship lift crosses dam method, the method are as follows:

1) run the ship reception chamber for carrying dam ship on the arc-shaped rail that both ends tilt, centre is low-lying, utilization is arc-shaped Rail high-low-high shape crossed the low-high-low movement on hillside when offsetting dam, form the balance of ship reception chamber, guaranteed ship mistake Horizontality is in when dam, with the safety of sharp ship's staff and cargo.

The above method is briefly exactly by ship in personnel and cargo and in the case where without departing from ship, uses vehicle will Ship integrally passes through the navigation channel between upstream and downstream, crosses dam.

The key for making ship cross dam is to keep ship holding during crossing horizontal.Since ship has been in water It is complete horizontal, so all facilities and cargo on ship are arranged according to level requirement, especially transported on inland river Capable ship, since stormy waves is smaller, ship does not consider generally to tilt larger situation, so, so that ship is crossed the emphasis of dam It is to keep the level of ship during crossing, reduces the tilting or excessive sinking of fore or stern, cause deck front and back Inclination, makes Cargo On Deck and the improper movement of article peculiar to vessel.

During ship crosses dam, mainly with slope change, it may occur however that the inclination of front and back, and tilting can be with It ignores.It avoids tilting forward and back, so that the horizontal the present embodiment of ship holding is taken a foolproof mode and keep holding ship The level in compartment: intermediate low-lying circular arc rail is tilted using a both ends, ship reception chamber is moved back and forth on arc-shaped rail, supports Disappear the inclination generated due to crossing dam.Movement of the ship reception chamber on arc-shaped rail is similar to seesaw, fully automated flat Weighing apparatus, without manually adjusting, overall structure very simple does not need a large amount of mechano-electronic control device, and operation cost drops significantly It is low.

2) in loading or unloading ship, the ship lift can directly be driven into water, make to rise using the buoyancy of buoyancy tank Ship machine is in partially surfaced condition, and compartment by ship is only entered or left with flag-on-convenience vessel.

In loading or unloading ship, ship lift is in partially surfaced condition, and the buoyancy that buoyancy tank generates keeps ship lift floating in water. At this moment the drinking water (e in Fig. 1) of buoyancy tank is greater than the drinking water (d in Fig. 1) of ship reception chamber, and the drinking water of ship reception chamber is greater than the drinking water of ship (c in Fig. 1), that is to say, that ship can float after unlocking hawser, into ship reception chamber.

The drinking water depth problem of float chamber: being the position according to circular arc rail radius, rail arrangement under ship reception chamber and low water What the phase river depth of water determined.Two rail of the present embodiment have been placed in the minimum position of ship lift, cannot be low again, low water The depth of water in phase river is also fixed (such as depth of water in Three Gorge Reservoir downstream is 5m).Therefore the deep drawing selection to float chamber Mainly determined by the radius of curvature size of rail, if the smaller rail both ends of radius of curvature to tilt it is higher, even if float chamber is eaten The depth of water be equal to 5m, ship also into not come because ship is blocked by rail；If the radius of curvature of rail is larger, when drinking water is slightly less than 5m deeply, Although ship can smoothly enter into ship reception chamber, when ship lift climb and fall ship reception chamber is moved to one end of rail, leave a liter ship Owner's body is farther out, dangerous.The present embodiment is tentatively optimized, and the radius of curvature of rail is selected as 60m, rail is slightly stretched at driver's cabin Longer, the rail of ship reception chamber opening does not extend, to guarantee that ship can pass in and out ship reception chamber, and meanwhile ship reception chamber opening is adjacent Two wheels hypotelorism 35.2cm, when making climb and fall, ship reception chamber both ends wheel is in the suitable position of safety.

The drinking water of float chamber is defined as 5m deeply, this just requires the depth of water of channel thread that cannot be less than 5m or neighbouring river first The ditch for having 5m mostly deep in road is half congealed, and ship lift ushers in and out ship at this, otherwise just needs to build in downstream ramp road exit bigger In the forebay of 5m depth, ship just can enter ship reception chamber.

It is required that the integrally-built total weight of ship lift (not including the weight of ship) should be the same as the buoyant equilibrium of float chamber.According to A Ji Mead principle, buoyancyFEqual to the weight for arranging androgynous ponding, that is, the volume that two float chamber drinking water depths are 5mVMultiplied by water Specific gravityγ , it may be assumed that

F=Vγ

In formulaγ Specific gravity=1 of watert/m ³。

By Fig. 2 E-E and F-FV=2*(20.8*4.6*5)= 956.8m ³ 。

Then buoyancy are as follows:

F=Vγ=956.8t。

The total weight G(of ship lift is free of the weight of general cargo) buoyancy F should be not less than, otherwise ship lift will float upwards Floating, float chamber drinking water is deep to be reduced, and ship cannot enter ship reception chamber.Solution is to fill lead in the crossbeam under rail and aggravate, make G and F reaches balance.Conversely, ship lift sinks if G ratio F is big, may sink to the bottom, the drinking water of float chamber is deeply more than 5m, as long as at this moment Ship lift and ship are not flooded not, and ship lift can still walk on riverbed freely and usher in and out ship.

Equilibrium problem about ship lift rear and front end weight: due to ship reception chamber front opening, installation is driven on the wall of rear end Room is sailed, interior is in addition to personnel, and there are also electromechanical equipment and batteries etc., increases weight, will in order to make ship reception chamber both ends weight balancing The tail portion of ship in ship reception chamber reaches the outside of ship reception chamber opening, or in lighter one lower beam inner canister lead.

It is 1.25m that ship, which absorbs water depth, and estimate the loading capacity of ship: the long 29m of ship, width 5.5m, drinking water depth 1.25m, ship is in water Volume V=29*5.5*1.25=199.38m ³ 。

Since the both ends of ship tilt, the volume of practical ship is smaller, about 150m³, i.e. buoyancy 150t carries Ship adds the weight of cargo, if ship own wt is 70t, goods weight is no more than 80t.

Finally it should be noted that being only used to illustrate the technical scheme of the present invention and not to limit it above, although referring to preferable cloth The scheme of setting describes the invention in detail, those skilled in the art should understand that, it can be to technology of the invention Scheme (such as integral form, power form, sequencing of step of ship lift etc.) is modified or replaced equivalently, without It is detached from the spirit and scope of technical solution of the present invention.
