Drum driving apparatus is communicated with a Hydraulic Station (also power set 2), and drives reel 320 to rotate.In the present embodiment, drum driving apparatus comprises the hydraulic motor 331 and the reducer 332 that are arranged on wall frame 312, the oil circuit of hydraulic motor 331 is communicated with this Hydraulic Station (also power set 2), and hydraulic motor 331 reducer 332 that is in transmission connection, the output shaft upper driving of reducer 332 be connected with the second gear 333, the second gears 333 and the first gear 323 intermeshing.By intermeshing the second gear 333 and the first gear 323, drum driving apparatus drives reel 320 to rotate, and by being in transmission connection of the first sprocket wheel 346 and the second sprocket wheel 324, realizes reel 320 and automatic cable arrangement device synchronization action.In the present embodiment, be balancing moment, drum driving apparatus is 2 covers, and namely hydraulic motor 331, reducer 332 and the second gear 333 are two, are symmetricly set on the both sides of reel 320.
Operating principle of the present invention and process prescription are 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 on the hammer body 11 of pile hammer body 1, and power set 2 and pile hammer body 1 are connected and fixed with bolt.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 is put 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 use respectively.Then the tracheae 62 that the cable 61 marine vessel power booster 41 being picked out, the power set control cable 63 that control device waterborne 43 picks out pick out with cartridge valve control cable 64, pneumatics unit 42 is connected with the slip ring system on winch sled 3, ensures the transmission of electric power, control instruction and pressure-air.
When the operation of deepwater hydraulic pile hammer, loop wheel machine peculiar to vessel is sling pile hammer body 1 from deck, coordinates underwater robot to put it in water.The Hydraulic Station that starts winch sled 3, makes reel 320 put umbilical cables 6 outward by automatic cable arrangement device.The cable releasing speed that regulates winch sled 3 according to the lowering velocity of pile hammer body 1, is consistent the two substantially.In the time that pile hammer body 1 is sent to the predetermined operation degree of depth, will hammer jacket casing rear piling work of preparing on default piling bar into shape.Then open successively marine vessel power booster 41, pneumatics unit 42 and control device waterborne 43.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 243 li of fuel tanks is delivered to oil distribution casing, pile hammer oil-feed cartridge valve, pile hammer oil-feed flange through hydraulic pressure oil inlet pipe, unlatching flow to into pile hammer oil cylinder piston rod are mentioned, and hammer core is also just raised thereupon; When pile hammer body is made 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, after being filtered, flow back to again fuel tank 243, recycle, complete once piling.
When the end of job of deepwater hydraulic pile hammer, first close marine vessel power booster 41 and control device waterborne 43 on ship deck, restart the Hydraulic Station of loop wheel machine peculiar to vessel and winch sled 3, pile hammer body 1 is recovered on ship.Prize 3 take-up speed when consistent when pile hammer body 1 recovery speed and winch, umbilical cables 6 is permanent tension force, 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.In the time that pile hammer body 1 recovery speed is less than winch and prizes 3 take-up speed, umbilical cables 6 tension force exceed setting value, and hydraulic motor 331 is in the passive state that drags, and winch is prized 3 passive cable layings to reduce tension force, and protection umbilical cables 6 is not pulled off; In the time that 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 prize 3 permanent tension value by flexible modulation winch, 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 machine group 42 and control device waterborne 43 provide compressed air and operational order, and can monitor state and the information data of pile hammer body 1, 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, the energy linear loss while avoiding providing power for pile hammer body 1 on the water surface; Winch sled 3 possesses automatically, multilayer, evenly arrange cable, braking, and permanent tension force, high pulling torque promote take-up function; Cable 61, power set control cable 63, cartridge valve control cable 64, tracheae 62, through the integrated umbilical cables 6 of slip ring system, do not affect electric power, signal and pressure-air and carry in the time of work, the protection to umbilical cables 6 while being convenient to different operating mode construction.The research and development of this deepwater hydraulic pile hammer complete the pile foundation operation that can make below the 1500m depth of water and come true, can be better for the mankind carry out deep-sea oil, mining mineral resource is served.
Technical scheme of the present invention is disclosed as above by preferred embodiment.Those skilled in the art should recognize change and the retouching the scope and spirit of the present invention that the appended claim of the present invention discloses, done in the case of not departing from, within all belonging to the protection domain of claim of the present invention.
