The present invention is provided for object is got to system in soil under water in one embodiment, and this system comprises: the hammer element; Frame construction, the hammer element is received in this frame construction; Piston rod, this piston rod is received in frame construction; Piston, this piston receiver is in piston rod; And piston rod, this piston rod has top and bottom, and this upper end is attached to piston; Coupling, this coupling is attached to the hammer element, and wherein, this coupling is fixed in the lower end of piston rod, and this coupling is suitable for making piston rod to move up and down in limited range with respect to the hammer element; Hydraulic Elements group, this Hydraulic Elements winding are contained in frame construction or are attached to this frame construction, and are communicated with the piston rod fluid; Surface texture on the water surface (can be applicable make ship or the barge of work boats and ships or be fixed in soil under water or be fixed near the platform of soil water); Lifting line, this lifting line extends between surface texture and frame construction; Operated from a distance submersible (ROV), this operated from a distance submersible is suitable for being operably connected to this Hydraulic Elements group; And umbilical cable, this umbilical cable is extended between surface texture and ROV, and be suitable for the signal of telecommunication and/or control signal from surface texture are offered ROV, be used for causing the hammer element repeatedly to move, carry thus in order to object is got to the strike in soil under water.

Yet, due to when promoting rammer piece 32, enter in adjustable air spring 80 from the hydraulic fluid above piston in piston rod 56, thereby apply additional force to ramming piece 32.Adjustable air spring 80 is separated into bottom compartment and top compartment by pouch barrier film 80c (Fig. An application of ramming equipment of the present invention is: for example be arranged in oil and gas industry and stake got to the ocean bottom soil of very dark water.With reference to Fig. The hammer element preferably comprises: the hammer piece; Top hammer piece guide, this top hammer piece guide axially extends upward from the hammer piece; And bottom hammer piece guide, this bottom hammer piece guide is from hammering piece into shape axially to downward-extension; Wherein, frame construction has upper opening and lower openings, and upper opening is suitable for admitting top hammer piece guide, and lower openings is suitable for admitting bottom hammer piece guide.Preferably, the hammer piece has axial hole; Top hammer piece guide and bottom hammer piece guide all have the hole of aiming at the hole in the hammer piece; Coupling is attached to the hammer piece or is attached to top hammer piece guide or bottom hammer piece guide, and is positioned at the hole of hammer piece, perhaps is arranged in the hole of top hammer piece guide or bottom hammer piece guide; And piston rod in the hole of top hammer piece guide to downward-extension.Frame construction preferably is suitable for allowing the current influent stream to go out, so that the hammer piece contacts with water under water the time.

Of the present invention beat or ramming equipment also can be used on during shallow water and roadbed use.Use for roadbed, ramming equipment shown in Figure 2 can be arranged on the truck with crane, and can come ramming equipment supply power from the equipment on truck.Use for shallow water, also can operate ramming equipment 30 from barge, and operate this ramming equipment from the structure that is anchored to the seabed.Ramming equipment 30 can be used in seawater and fresh water.

Can by valve 84c with the filled lower end 56e to low pressure pouch 84 and piston rod 56 of hydraulic fluid, reach and discharge hydraulic fluid from the lower end 56e of low pressure pouch 84 and piston rod 56.Can hydraulic fluid be filled to the upper end of adjustable air spring 80 and piston rod 56 by valve 80b, and discharge hydraulic fluid from the upper end of adjustable air spring and piston rod 56.Adjustable air spring 80 has pouch barrier film 80c in inside, and gas can fill by valve 80d the upper end to adjustable air spring 80 above pouch barrier film 80c.The pressure of adjustable air spring 80 inside is preferably higher than the expection hydraulic pressure of adjustable air spring 80 outsides, and this expection hydraulic pressure will depend on the operational depth of ramming equipment 30.Low pressure pouch 84 has pouch barrier film 84d, and is provided with and fills material valve 84e, and this fills the material valve and is used for above pouch barrier film 84d fluid-filled to low pressure pouch 84.Fill and expect that valve 84e is filled to water in low pressure pouch 84 above being used in pouch barrier film 84d, then when dropping to low pressure pouch 84 in deep water, make to fill and expect that valve 84e opens to carry out pressure compensation.Artificial bypass line 84f and valve 84g (usually closing) can be used for by hydraulic fluid is discharged in low pressure pouch 84, comes the pressure in the lower end 56e of release plunger cylinder 56 by line 84f.The reply hydraulic circuit carries out various adjustment before disposing ramming equipment, with ramming equipment that the water that is used in certain depth is operated and the initial hoisting depth of hammer piece is set and regulated.Specifically, should check by the adjustment screw to adjustable air spring 80, low pressure pouch 84, feeling of stress side valve 82 and spring 82d before disposing.

8 in monitoring piston rod 56 tops, and this pressure is used for the maximum lifting height that piece 32 is rammed in representative, and the position of the top jaw 56j on piston rod 56i is used for the maximum lifting height that piece 32 is rammed in representative in Fig. Described piston rod in the hole of described top hammer piece guide to downward-extension. 5, and in upward stroke, pin 54e is resisted against the wall bottom that limits opposed slot 54d, rams piece 32 for piston rod 58 provides substantially rigid to connect to promote.When descending stroke begins, institute’s Compressed Gas in adjustable air spring (Fig.

And described coupling is adapted to: when upwards promoting described hammer, the connection between described piston rod and described hammer is substantially rigid, and when described hammer arrived its extreme lower position, the connection between described piston rod and described hammer was nonrigid. 8), and this motor 74 is connected in pressure compensation variable delivery pump 92 by line 74a as shown in the figure, and this variable delivery pump 92 substitutes pump 76 and safety valve 86 shown in Figure 8.Come the liquid stream of self-pumping 92 according to the automatic self-control of back pressure of discharging at it on side, and this depend on whether hydraulic fluid flows through flap valve 92a, line 92b also by directional control valve 78 (describing with reference to Fig. 2, yet what will illustrate is that the horizontal part 62c of tube frame is ” U ” shape substantially, and near being not attached to hydraulic pressure framework 44.Hydraulic pressure time framework 62 only is attached to shock and vibration isolator 64, makes that produce, minimum for the shock and vibration of hydraulic unit thereby make when ramming 32 shock liners 48 and anvil block 50.The ROV control arm grasps bar 62d and 62e to be ramming equipment or to beat equipment 30 and be provided at a structure on hydraulic pressure time framework 62, and ROV can make and himself is anchored to this structure.Protected apron 62f provides the surface that hydraulic unit can be installed, and protects these hydraulic units not impaired.
