As Figure 1-3, the present invention is made up of two slideways, 11, two slide units, some crossbeams 15 and two power parts for the device 1 of translation jumbo ship complete cross section.
Wherein, two slideway 11 parallel laid are on ground, and its width between centers is 11 meters, long 56 meters of every bar slideway 11.Preferably, slideway 11 selects 8 meters long, and 1.7 meters wide, and the steel plate splicing of 44 millimeters thick forms (length of slideway, the size of steel plate are all determined according to actual conditions, these are only citing).At the affixed stainless steel mirror in the surface of every bar slideway 11, and the reaction support 13 that two rows are parallel to each other is set in the line of centers both sides of every bar slideway 11, often arranges reaction support 13 and there is several teeth groove 131 (as shown in Figure 2).The reaction support 13 of this spline-simulating serves the effect of counter-force support and restriction boats and ships complete cross section 2 radial runout in slipping.
In addition, reaction support 13 can be shaping by plasma cutter time processing, and working accuracy is high.Two reaction supports 13 that every bar slideway 11 correspondence is arranged are parallel installation, can once form multiple reaction support, reduce making and the installation difficulty of reaction support 13
Preferably, the surface of slideway 11 is provided with two grooves, and stainless steel mirror has two flangings.Further, stainless steel mirror is rolled over limit in 90 °, described two flanging correspondences are embedded in described two grooves.This flush type mounting structure can prevent stainless steel mirror in slipping because of " nose " with slide unit slippage effectively.Therefore, whole steel plate needs the groove first processing to inlay stainless steel mirror thereon before a splice, and stainless steel mirror is laid immediately on slideway 11 after flanging.
Wherein, each slide unit comprises one and is held on slide plate 14 on corresponding two row's reaction supports 13.Be installed with some to piston shoes 12 in the lower surface of slide plate 14, and in the bottom of piston shoes 12 an affixed polyfluortetraethylene plate 121.Adopt polyfluortetraethylene plate 121 to slide on stainless steel mirror and realize translation, its friction coefficient is suitable with slipway launching steel ball friction coefficient.And polyfluortetraethylene plate 121 and ground are that face contacts, lower to ground requirement of strength.
Piston shoes 12 play carrying and antifriction effect in whole slipping, and it can increase in slipping the area transmitting vertical load, reduce the local pressure of slideway, increase the safety of slippage.Preferably, piston shoes 12 are made into block of wood shape, and polyfluortetraethylene plate 121 is fixed on bottom block of wood by flat machine screw.Further, in order to prevent flat base screw in slipping from being caused polyfluortetraethylene plate and block of wood to misplace by cutting off, a postive stop baffle can be welded in the junction of piston shoes 12 and polyfluortetraethylene plate 121.
Slide plate 14 is welded successively by some pieces of slide blocks.Now, slide block lower end described in every block at least sets firmly two pairs of piston shoes 12, and often pair of piston shoes 12 are symmetrically set in the both sides that two of correspondence arranges reaction supports 13.Because the length of boats and ships complete cross section 2 is very long, therefore adopting some pieces of slide blocks to be welded into can reduce manufacture difficulty, is also convenient to the length lengthening or shorten described slide plate.Further, at least connect two horizontal guide sheave (not shown) in the bottom of slide plate 14, be arranged between two corresponding reaction supports 13.The preferred heavy deep groove ball bearing of horizontal guide sheave, is connected to slider bottom by base plate.In slipping, horizontal guide sheave acts on the teeth groove 131 of reaction support 13, can limit the generation of slide block horizontal radial displacement.

Wherein, two power parts are fixed in an end of corresponding slide plate 14 respectively, move forward for promoting described slide unit.Preferably, described power part is hydraulic ram 3, and one end is provided with a counter-force and supports shoulder pole 31.By hinged to hydraulic ram 3 and slide plate 14, and the two ends that counter-force supports shoulder pole 31 are held in a pair teeth groove of two row's reaction supports 13 respectively.
Present invention employs hydraulic synchronization sliding technology, namely adopt hydraulic ram 3 as slippage driving arrangement.Hydraulic ram 3 is when thrusting slip starts and brake, and complete cross section can not be made to shake because of the extension of flexible wire ropes or vibration, mobile stationarity is higher.
In addition, for ensureing the levelness of slideway, reducing sliding friction coefficient, preventing stainless steel mirror from moving with piston shoes in slipping, slideway and stainless steel mirror should be accomplished when making and laying: need bottom slideway to level up, pad, slideway and ground are without clear gap; Slideway upper surface should carry out hand cleaning, polishes smooth; The whole plate connector diff-H range estimation of slideway is zero, does not allow two plate connectors to have the situation of high infraversion malposition to occur; Slideway line of centers locating bias degree controls within 3mm; When formal slippage, stainless steel mirror and piston shoes contact surface need coating lubricating oil to reduce friction coefficient etc.
And reaction support 13 can make the application force of hydraulic ram 3 and the glide direction maintenance level of boats and ships complete cross section 2, avoids the generation of other direction component.When meeting intensity, need to ensure that the center of effort line of hydraulic ram 3 is below the line of centers of reaction support 13 upper end.And when meeting hydraulic ram installation dimension, the parallel distance between two reaction supports 13 should be as far as possible short.
As shown in Figure 4, the present invention adopts the method for said apparatus translation jumbo ship complete cross section specifically to comprise the following steps:
Step 100, the crossbeam of described device carries and fixes a boats and ships complete cross section.
Step 101, removes the obstacle on described slideway.
Step 102, checks that whether described slideway joint is smooth, guarantees the situation without high infraversion malposition.

Step 107, described piston rod stretches out and promotes described counter-force and supports shoulder pole, and described hydraulic ram is along piston rod oppositely movement.
Step 108, described hydraulic ram promotes to stop after described slide plate moves forward a stroke.
Step 109, the described piston rod of described hydraulic ram is retracted, and described counter-force is supported shoulder pole and moves in next rach slot.
Step 110, whether slippage is to assigned address to judge described boats and ships complete cross section; If so, then step 111 is entered; If not, then step 106 is returned.
When carrying out pushing tow work, hydraulic cylinder piston rod stretches out, and acts on counter-force and supports on shoulder pole.Due to reaction support teeth groove place restrictions on effect, the reversing sense that oil cylinder stretches out along piston rod moves.Meanwhile, hydraulic ram promotes slide plate and moves forward a stroke (as 600 millimeters).After a stroke, slide plate and hydraulic ram all maintain static, and piston rod is retracted to hydraulic ram.Now, removing to next teeth groove by manually counter-force being supported shoulder pole, restarting to pass next time.So repeatedly complete cross section can be slid onto assigned address.
Step 111, stops described hydraulic ram, completes the translation of described boats and ships complete cross section.
