Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The present invention is directed to self lift type wind turbine installation vessel and build a kind of shoe being convenient to pile pulling proposed, as shown in Figure 1, shoe of the present invention comprises guide peg 1, base plate 2, connecting rod 3, piston rod 8, fagging seat 9 and fagging 10, piston rod 8 comprises piston rod 5, piston 6 and back-moving spring 7, back-moving spring 7 top is fixedly connected with piston rod 8 inside upper part, its bottom is fixedly connected with piston 6 end face, piston 6 bottom surface is fixedly connected with piston rod 5 top, wherein piston rod 8 is fixed, is sealed in spud leg 4 inside, enters piston rod inside to stop seawater and silt.Piston rod 5 bottom and base plate 2, guide peg 1 are fixedly connected sequentially, base plate 2 and being in transmission connection successively between connecting rod 3, fagging 10 and fagging seat 9, and fagging seat 9 is fixed on spud leg 4.Piston rod 8 upper and lower side is provided with pore and gives vent to anger, prevent piston rod 8 internal gas pressure from sharply raising because of pressurized, thus hinder piston 6 to move, also be provided with sealing ring between piston rod 5 and piston rod 8, piston rod 8 lower end is designed to taper shape, can prevent sandstone from blocking, cone has certain height, not only play spacing effect, be used for preventing back-moving spring 7 pressurized from transshipping, circular cone outline can also be utilized to prevent the obstruction of sandstone.The power of fagging 10 relies on connecting rod 3 and base plate 2 to transmit.
Present invention also offers a kind of using method of above-mentioned shoe, during pile sinking, shoe is in closure state as shown in Figure 2, now fagging 10 is vertical state, whole shoe resistance is little, be beneficial to spud leg 4 to sink seabed, in the process of sinking, the resistance that base plate 2 is subject to seabed is increasing, utilize the guide effect of piston rod 5 and piston 6 simultaneously, base plate 2 moves upward, promote piston rod 5, piston 6 moves up, make back-moving spring 7 pressurized, resistance also passes to connecting rod 3 by base plate 2 and then drives fagging 10, thus the fagging 10 promoting surrounding opens, fagging 10 is because being subject to the inhibition of fagging seat 9, maximumly go to level, to increase the contact area of spud leg 4 and seabed, now guide peg 1, base plate 2, connecting rod 3 inserts seabed, fagging 10 contacts with institute seabed, substantially increase the stability of spud leg 4.
During pile pulling, shoe is in open configuration as shown in Figure 1, now fagging 10 is level, utilizes the reset function of back-moving spring 7 in piston rod 8 and the effect of gravity, and promotion piston 6, piston rod 5 move down together, piston rod 5 drives base plate 2, connecting rod 3, guide peg 1 to moving down, thus drive fagging 10 inwardly to swing around fagging seat 9, until the vertical state of fagging 10 one-tenth, thus reduce pile extraction resistance, now guide peg 1, base plate 2, connecting rod 3 aweigh, improve pile pulling efficiency.
Preferably, fagging seat 9 as shown in Figure 3, be provided with the groove of multiple symmetry, match with the upper end of the fagging 10 shown in Fig. 4,8 faggings can be installed, further simultaneously, base plate 2 also can be provided with 8 corresponding with it connecting rods, can be dynamically connected with 8 faggings, considerably increase the contact area in spud leg and seabed, make spud leg more firm.
Shoe of the present invention and using method thereof are compared with the shoe used at present, there is remarkable advantage: this shoe is when pile sinking, utilize the base plate be arranged on below spud leg, the fagging promoting surrounding by connecting rod because of the inhibition in seabed opens, increase the contact area in spud leg and seabed, improve the stability of spud leg; During pile pulling, utilize the back-moving spring in piston rod, promote piston, piston rod and base plate and move down together, drive fagging inwardly to swing by connecting rod, reduce pile extraction resistance.Piston rod lower end is designed to taper shape, not only prevents sandstone from blocking, and because cone has certain height, can also play spacing effect, prevent back-moving spring from transshipping.Overall structure is simply compact, easy to use, while guarantee spud leg stability, reduces pile extraction resistance, improves production efficiency, build project provide brand-new structure for self-elevating ocean platform.
