Operating principle of the present invention and process prescription as follows:
Before deepwater hydraulic pile hammer of the present invention operation, first pile hammer body 1 is stood up on ship deck, then power set 2 are sling, be enclosed within the hammer body 11 of pile hammer body 1, and with bolt, power set 2 and pile hammer body 1 are connected and fixed.The two ends up and down of hydraulic pressure oil inlet pipe are connected with the oil-out of pile hammer body 1 oil-feed flange and oil distribution casing respectively; The two ends up and down of hydraulic oil-returning pipe are connected with the oil-in of pile hammer body 1 oil return flange and oil distribution casing respectively.Winch sled 3 puts a part of umbilical cables 6, after umbilical cables 6 is connected and fixed by umbilical cables joint flexible pipe and pile hammer body 1, then cable 61, power set control cable 63, cartridge valve control cable 64, tracheae 62 are connected with power set 2 and the quick watertight connector of pile hammer body 1 respectively.Then the power set that the cable 61 picked out by marine vessel power booster 41, control device waterborne 43 pick out control the tracheae 62 that cable 63 controls cable 64 with cartridge valve, air-compressor set 42 picks out and are connected with the slip ring system that winch is prized on 3, ensure the transmission of electric power, control instruction and pressure-air.
During the operation of deepwater hydraulic pile hammer, pile hammer body 1 is sling from deck by loop wheel machine peculiar to vessel, coordinates underwater robot to put it in water.Starting the Hydraulic Station of winch sled 3, making reel 320 by putting umbilical cables 6 outside automatic cable arrangement device.Regulate the cable releasing speed of winch sled 3 according to the lowering velocity of pile hammer body 1, make the two substantially be consistent.When pile hammer body 1 is sent to the predetermined operation degree of depth, after hammer jacket casing is on default piling bar, prepare piling work.Then marine vessel power booster 41, air-compressor set 42 and control device waterborne 43 is opened successively.By control device 43 waterborne, power set 2 are started working.The motor 223 of cable 61 driving power device 2 drives hydraulic pump 225 to work, by the pressure-control valve group 13 on power set 2, the hydraulic oil of fuel tank 243 li is delivered to oil distribution casing, flow to piston rod is mentioned into pile hammer oil cylinder through the pile hammer oil-feed cartridge valve of hydraulic pressure oil inlet pipe, unlatching, pile hammer oil-feed flange, hammer core is also just raised thereupon; When pile hammer body makes piling bar 1 time, pile hammer oil return cartridge valve is opened, oil-feed cartridge valve is closed, hydraulic oil in oil cylinder flows back to the pressure-control valve group 13 on power set 2 by the oil-in of pile hammer oil return flange, hydraulic oil-returning pipe and oil distribution casing, fuel tank 243 is flowed back to again after being filtered, recycle, namely complete and once drive piles.
During the end of job of deepwater hydraulic pile hammer, first close the marine vessel power booster 41 on ship deck and control device waterborne 43, restart the Hydraulic Station of loop wheel machine peculiar to vessel and winch sled 3, pile hammer body 1 is recovered on ship.When pile hammer body 1 reclaim speed and winch prize 3 take-up speed consistent time, umbilical cables 6 is identical tension, and winch sled 3 is always take-up pattern, and this oil pressure relief is setting value, and umbilical cables 6 can keep some tension.When pile hammer body 1 reclaim speed be less than winch prize 3 take-up speed time, umbilical cables 6 tension force exceedes setting value, and hydraulic motor 331 is in passive dragging state, and winch prizes 3 passive cable layings to reduce tension force, protection umbilical cables 6 be not pulled off; When tension force is less than setting value, winch sled 3 initiatively take-up again, keeps tension force constant.By the oil pressure relief of regulation relief valve, can flexible modulation winch sled 3 identical tension value, to meet job requirements.
Advantage of the present invention and beneficial effect are:
The pile hammer body 1 of this deepwater hydraulic pile hammer can lead to power set 2 provides power, on ship, air-compressor set 42 and control device waterborne 43 provide compressed air and operational order, and state and the information data of pile hammer body 1 can be monitored, and then realize the piling work of long-range cooperation pile hammer body 1 on the water surface; Power set 2 are integrated on pile hammer body 1, avoid being energy linear loss when pile hammer body 1 provides power on the water surface; Winch sled 3 possesses automatically, multilayer, evenly arrange cable, braking, and identical tension, high pulling torque promote take-up function; Cable 61, power set control cable 63, cartridge valve controls cable 64, tracheae 62 through the integrated umbilical cables 6 of slip ring system, operationally do not affect the conveying of electric power, signal and pressure-air, are convenient to the protection to umbilical cables 6 when different operating mode is constructed.The research and development of this deepwater hydraulic pile hammer complete and the pile foundation operation of below the 1500m depth of water can be made to come true, can better for the mankind carry out deep-sea oil, mining mineral resource and serving.
Technical scheme of the present invention is disclosed as above by preferred embodiment.The change that those skilled in the art do when should recognize the scope and spirit of the present invention disclosed in the claim do not departed from appended by the present invention and retouching, within the protection domain all belonging to claim of the present invention.
