Water launches boost installation under the ocean engineering structure slippage
Technical field
The present invention relates to launch boost installation, relate in particular to that water launches boost installation under a kind of ocean engineering structure slippage that is used for water test under the ocean engineering structure model.
Background technology
Some ocean engineering structures need haul the place of erection by barge as jacket, ultra-large type buoyancy aid module, marine floating (SPAR) platform etc., then, slip into the water from barge.The buoyancy aid itself when guaranteeing water under the ocean engineering structure and the structural safety of barge can be carried out the following water test of model usually.During water test, the barge model is a heeling condition under carrying out model, relies on the self gravitation effect overcome friction after model tilts, and makes model slide barge, water under the implementation model.
Yet the static friction force that the neatly shifting state need overcome under model was transferred to by quiescence is often bigger, relies on self gravitation to overcome, and at this moment, just needs the outside to apply initial action power to help to overcome static friction force.At present, owing to there is not the special device of propelling, the outside applies initial action power is generally undertaken by manual operation, is to apply enough big initial thrust by the people promptly, makes model transfer neatly shifting state down to by quiescence.Owing to the manual operation inconvenience, be not easy to control the direction of initial thrust, the size of more difficult control initial thrust, therefore, the dynamic process of water model and barge brings influence to accuracy of experimental results under also disturbing easily.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that prior art exists, and water launches boost installation under a kind of ocean engineering structure slippage and provide, and it can accurately be simulated ocean engineering structure and refute launched process; Accurately the direction of control initial thrust and the size of initial thrust are easy to operate, lay a good foundation for finishing under the model water test accurately.

The specific embodiment
As Fig. 1-shown in Figure 4, the present invention includes: propelling unit 1, fixed bearing 2, feedway 3, connection mode is: propelling unit 1 is connected with fixed bearing 2, and feedway 3 is connected with fixed bearing 2.
As shown in Figure 1, propelling unit 1 comprises: push pedal 4, spring 5, movable axis 6, sleeve 7, base plate 9, handle 10, wherein, push pedal 4 and base plate 9 are flat board, and it all has each two of borings near the center line both sides, movable axis 6 is the cylindrical, massive axle, sleeve 7 is a hollow cylinder, and its internal diameter is more slightly bigger than movable axis 6, and movable axis 6 can be passed freely through, sleeve 7 external diameters are a little littler than spring 5 internal diameters, so that spring can overlap thereon for 5 one sections.Movable axis 6 rear and front ends are respectively equipped with screw thread, and fix with the boring of push pedal 4, base plate 9, and movable axis 6 passes sleeve 7, and sleeve 7 is fixed on the pedestal 8 on the fixed bearing 2.Spring 5 is enclosed within movable axis 6 outsides, and spring 5 front and back ends withstand on a side of push pedal 4 and a side of pedestal 8 respectively, and a side of base plate is equipped with U-shaped handle 10.By acting on handle 10 pulling force push pedal 4, movable axis 6, base plate 9 are moved backward towards direction of pull, simultaneously, spring 5 is because the motion of push pedal 4 and pedestal 8 keeps motionless, and the effect of being under pressure can be compressed.
As shown in Figure 2, fixed bearing 2 comprises: pedestal 8, fixed pedestal 11 and pedestal brace panel 12, and pedestal 8 is square plates, and two borings are arranged on it, movable axis 6 passes boring on it; Fixed pedestal 11 is L type angle steel; Pedestal brace panel 12 is that the squarish plates are protruded on upper and lower both sides, and two borings identical with pedestal 8 are arranged on it.Fixed pedestal 11 is fixed on the barge, and pedestal 8 is by End rivet is fixing with fixed pedestal 11 down, and pedestal brace panel 12 is fixed on the pedestal 8 by screw, the boring coincidence of two boring and pedestal 8 on it.Pedestal brace panel 12 act as: the contact surface of base plate 9 and pedestal 8 in the Control work process, and to guarantee the stable of pedestal 8.
As shown in Figure 3, feedway 3 comprises: deduction 13, slide-bar 14, nut 1, slide block 16, nut 2 17, nut 3 18, scale sign 19.Slide-bar 14 has scale mark for being threaded cylindrical shaft on its axle, can determine starting force by scale mark, and the one end is fixed by the screw on the pedestal 8; Nut 1, slide block 16, nut 2 17, nut 3 18 are nested in respectively on the slide-bar 14, and all can slide at slide-bar 14 upper edge axles.Slide block 16 is fixed on the slide-bar 14, and deduction 13 is a J-shaped, and deduction 13 is fixed on the slide block 16 by screw, and with slide block 16 motions, deduction 13 front ends can block base plate 9.Nut 1 and nut 2 17 lay respectively at slide block 16 both sides, are used for fixing slide block 16, i.e. the fixing position of deduction 13.
Feedway has the function of pinning propelling unit and discharging propelling unit, and can determine slide block 16 locked positions under the required starting force according to the scale mark that is located at the slide-bar 14 on the feedway.Push pedal 4 can act on starting force is provided on the offshore platform model when discharging propelling unit.
During concrete work, determine the position of slide block 16 on slide-bar 14 by the starting force of needs by the scale mark on the slide-bar 14 earlier, and with nut 1 and nut 2 17 that slide block 16 is fixing; Then, application force makes base plate 9 move to the position that deduction 13 just blocks on handle 10, then, deduction 13 is pinned; In process of the test, when beginning to apply starting force to model, preorder work pulls deduction 13 when finishing, under the effect of the power of spring 5, starting force on push pedal 1 action model, then, model is at this starting force effect lower slider and final water down.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
