5,6 and 8) of pipe 56c (admitting line 78b) at the lower end of frustoconical groove 56g, be arranged in the sidewall of piston rod 56.The downward teat 56f of frustoconical, frustoconical groove 56g and port 56h should be designed to: when descending stroke approaches end, piston 56a and piston rod 58 are slowed down, thereby when downward teat 56f near piston rod 56 bottom the time, downwards teat 56f begins the mobile of hydraulic fluid that flows out from piston rod 56 lower end 56e limited.During mobile being limited of flowing out from lower end 56e when hydraulic fluid, the downward speed of piston 56a must slow down, and this prevents the piston 56a lower end 56e of piston rod 56 that fiercelys attack.With reference to Fig.

In one embodiment, coupling mechanism comprises: hollow tubular bar Connection Element, and this hollow tubular bar Connection Element has lower end and upper end; The hammer Connection Element, this hammer Connection Element has longitudinal component and lateral part, and wherein the lateral part is received in hollow tubular bar Connection Element; And spring assembly, this spring assembly is received in hollow tubular bar Connection Element between the lateral part of the upper end of hollow tubular bar Connection Element and hammer Connection Element, and wherein hammering Connection Element into shape can move back and forth in limited range with respect to hollow tubular bar Connection Element.When promoting described hammer, the lateral part of this hammer Connection Element is pressed against the lower end of hollow tubular bar Connection Element, to provide substantially rigid to connect between piston rod and hammer, and preferably, when downward promotion hammer, move away from the lower end of hollow tubular bar Connection Element and be pressed against spring assembly in the lateral part of hammer Connection Element.Preferably, just before hammer collided anvil block, the downward speed of piston rod was slowed down.

2) by unshowned device (by the operator’s Long-distance Control on the water surface) with self being attached to, and use executor 72b, effuser 72c being connected in the inlet outlet connector 62g on protected apron 62f, and inflow pipe 72d is connected in goes out opening connector 62h on protected apron 62f.Then, executor 72b is used for opening installation in valve 62i and the 62j of protected apron 62f.Under the condition that pipe 72c is connected with 72d and valve 62i and 62j open, pressurized hydraulic fluid flows out, flows into fluid pressure motor 74 by valve 62i from ROV72 by effuser 72c, by valve 62j outflow and be back to ROV72 by inflow pipe 72d.Hydraulic fluid from ROV72 rotates fluid pressure motor 74, and this fluid pressure motor drives hydraulic pump 76 as shown in line 74a.Fluid pressure motor 74 and hydraulic pump 76 are installed on hydraulic pressure time framework 62, but also not shown in Fig.
3-7, ram piece 32 and have bottom rammer guide 32c and top rammer guide 32d, these two guides are respectively from ramming piece 32 bodies downwards and extending upward, be used for leading to ramming piece 32, and make rammer piece 32 keep vertical with piston rod 58 with piston rod 56, axially align.With reference to Fig. In another embodiment, the invention provides with object get under water as in system, this system comprises: hammer or ram, this hammer or rammer are suitable for object is got under water in soil; Hoisting mechanism, this hoisting mechanism operationally is connected in hammer, and this hoisting mechanism is suitable for lift hammer; Relieving mechanism, this relieving mechanism operationally is connected in hoisting mechanism and/or hammer, and this relieving mechanism is suitable for discharging hammer after hammer is raised; Framework, this framework is suitable for operationally admitting hammer; Structure on the water surface; Lifting line, this lifting line is between the lifting connector on water surface structure and framework; Operated from a distance submersible (ROV); The ROV umbilical cable, this ROV umbilical cable is extended between water surface structure and ROV, and this ROV umbilical cable is suitable for electricity and control signal from water surface structure are offered ROV; And the hammer umbilical cord, this hammer umbilical cord is suitable between ROV and hoisting mechanism operationally extending, so that ROV can activate hoisting mechanism, and ROV has the propulsion system that makes the ROV motion, and this ROV is suitable for the hammer umbilical cord is operably connected to hoisting mechanism.Hoisting mechanism preferably comprises hydraulic cylinder, this hydraulic cylinder has the piston that is positioned at wherein and is attached to the piston rod of this piston, piston rod is attached to hammer in order to lift hammer, and relieving mechanism also comprises pushing mechanism, and this pushing mechanism is suitable for hammering into shape promoting downwards together with piston rod hammer is released after.Preferably, piston rod is suitable for when hammer arrives its extreme lower position, prevents that piston rod from promoting hammer downwards for hammer attached.Preferably, pushing mechanism is adapted to: just before hammer arrived its extreme lower position, the downward speed of piston rod was less than the downward speed of hammer.Piston rod preferably is adapted to for the attached of hammer: when hammer was moving upward, the connection between piston rod and hammer was substantially rigid, and when hammer arrived its extreme lower position, the connection between piston rod and hammer was nonrigid.
