[specific embodiment]
The utility model is by overflow valve, solenoid electric valve 30, accumulator 31, oil hose 32, barrel support, guide upright post 17 and hydraulic pressure hammer body 3 are formed, hydraulic pressure hammer body 3 is embraced by four supporting legs and is clamped two guide upright posts 17, hydraulic pressure hammer body 3 is mainly by hammer stem 4, hydraulic jack 6, piston rod 9, piston 7 reaches, lower sleeve gasket 8,5 constitute, hydraulic pressure hammer body 3 tops are last hammer lid 10, one of piston rod 9 is fixed on hammer and covers on 10, hydraulic jack 6 is installed in upper end, hammer stem 4 the insides, upper sleeve gasket 8 is fixed on hydraulic jack 6 upper ends, lower sleeve gasket 5 is fixed on hydraulic jack 6 lower ends, last hammer covers 10 and is provided with oil-feed interface 12, oil distribution casing 13 and oil-out 14, oil-feed interface 12, oil out port 14 connects oil hose 32, oil hose is connected with barrel support, barrel support is by cylinder 26, sealing swivel joint 27, support 28 and Mainspring type flat spring 29 constitute, undercarriage also presss from both sides by supporting leg embraces above-mentioned two guide upright posts 17, and the hammer body bottom is provided with pile cover 1 and hammer anvil 2.Be provided with electric quick control elements A below last hammer covers 10, also be provided with electric quick control elements B on hammer body bottom, the hammer anvil 2.
The utility model is to adopt high-power Diesel engine or high-power electric work machine to be used as power, and drives high-pressure oil pump work.The pressure oil of oil pump output by oil pipeline, is received on the oil-feed interface 12 of hydraulic pile hammer top oil distribution casing 13.The left oil duct of pressure oil through piston rod 9 inside enters the top of oil cylinder 6.Pressure oil produces the active force that upwards pushes away between the upper sleeve gasket 8 of piston 7 and oil cylinder upper end.Upper sleeve gasket 8 is to be fixed on oil cylinder 6 upper ends, and oil cylinder 6 is again to be fixed on hammer stem 4 upper ends, and hydraulic oil upwards promotes oil cylinder 6 and hammer stem 4.At this moment the hydraulic oil of oil cylinder 6 bottoms returns fuel tank from the right passage of piston rod 9 inside through oil-out 14 and rubber hose.When hammer stem 4 rose to top dead centre, electric quick control elements A road was logical, made hydraulicdirectional control valve change the direction of turnover hydraulic oil.At this moment the right passage in the piston rod 9 becomes oil-feed, and pressure oil enters oil cylinder 6 bottoms.Produce downward push oil cylinder 6 of active force and hammer stem 4 between piston 7 and lower sleeve gasket 5, the weight that adds hammer stem 4 self is damping of shocks pad 24 and hammer anvil 2 downwards fast, and hammer anvil 2 impacts concrete stake pipe 15 under the guiding of pile cover 1.When hammer stem 4 impacted lower dead center downwards, the logical reversal valve in electric quick control elements B road changed hydraulic oil turnover direction, and hammer stem 4 moves up again.Hammer stem 4 back and forth impacts concrete stake pipe 15 downwards up to the concrete stake pipe is driven underground like this, and hydraulic pile hammer quits work.
When guaranteeing that hammer anvil 2 moves up, the silt on the concrete stake pipe 15 is not brought in the pile cover 1, the spy has installed dust ring 25.
Four supporting legs, 20 folders of the undercarriage 22 of the utility model hydraulic pile hammer are embraced two and are led column 17.After a cement pipe pile was accomplished fluently, the wire rope 23 of electric winch (machine is raised in commentaries on classics) loosened, and the wire rope that at this moment loosens makes undercarriage along the 17 downward landings of two guide upright posts by pulley.
When sliding under the undercarriage when rising and falling hook 18 positions, manually shake rope 19 and make and tangled off the hook 18, the upwards traction of wire rope 23 of electric winch (machine is raised in commentaries on classics) at this moment.Four supporting legs 16 on the hydraulic pressure hammer body 3 also press from both sides embraces two guide upright posts 17, and whole hammer body is moved up along guiding force post 17.Whole when hammering certain altitude into shape, another root cement pipe pile can be installed.Winch (machine is raised in commentaries on classics) drop is pushed down cement pipe pile, opens hydraulic pile hammer and proceeds to make a call to second concrete stake.
Hydraulic oil of the present utility model must be transported on 12,14 two oil-collecting holes of peen portion, and is very inconvenient when two big rubber tubes are worked in tow, so connect fixedly steel pipe in this section of the utility model hammer body, connects rubber hose outside the hammer body.Pipeline is very long when the utility model rises to the top, the work that cement pipe pile was installed in a lot of on the ground influences of rubber tube dish when the utility model was got to the bottom.Thereby designed the barrel support of being made up of cylinder 26, sealing swivel joint 27, support 28, Mainspring type flat spring 29, when hydraulic pile hammer rose, the oil pipe on the barrel support rose with hammer and extends.When hydraulic pile hammer descended, the Mainspring type flat spring 29 automatic rotary drums in the barrel support unrolled oil hose on cylinder.The pressure oil of oil pump output is received in the sealing swivel joint 27 of barrel support through petroleum pipeline.This sealing rotation pipeline joint can not make oil hose be twisted together when swing roller, guarantees that effectively the fuel feeding road is unimpeded.
The utility model is this to be installed in design in hammer stem 4 bodies with hydraulic jack 6, has reduced the length of a hydraulic cylinder.Hammer body outside year, component such as piston rod made whole hammer seem very compact less than oil cylinder.
In addition, piston rod 9 of the present utility model, piston 7 and hydraulic cylinder 6 threes combination have three kinds of forms.Consulting Fig. 4 is at hydraulic jack sealed fairlead 8 and 5 to be housed up and down.Turnover two oil ducts (left oil duct and right oil duct) are arranged in the middle of the piston rod 9, by reversal valve control hydraulic oil is formed upwards pushes away or to the active force that presses down oil cylinder in piston 7 upper and lowers, make hydraulic jack 6 drive hammer stem 4, move back and forth up and down, reach the effect of piling along piston rod 9.Consult Fig. 5: have only a pipeline in the piston rod 9, when hydraulic oil enters, produce the active force that upwards pushes away between piston 7 and the last sealed fairlead 8, promote hydraulic jack 6 and drive hammer stem 4 risings.When release, hydraulic oil is along the former road of piston rod 9 interior conduits oil sump tank, and hammer stem 4 freely falling bodies hit cushion pad 24 downwards and hammer anvil 2 is driven piles.The hole C of hydraulic jack 6 lower ends is ports, unlikely generation air resistance when hammer stem 4 moves up and down.Consult Fig. 6: also have only a passage in the piston rod 9, its operating principle is the same with Fig. 5, but the lower end of hydraulic jack 6 opens wide, and oil gas is in line, and its resistance was littler when hammer stem impacted downwards.
Must be below piston when adopting the open type hydraulic jack, the hammer anvil bottom loads onto dust ring 25 and keeps the oil cylinder inner surfaces cleaning.Fig. 5 and piston rod shown in Figure 6 the inside all have only a passage, and hammer stem is that hydraulic oil does not add any active force in lower part of piston to cylinder by the hammer stem own wt when falling, so produce reaction force upwards can not for whole hammer body when hammer stem falls.Whole hammer body and hammer carrier are all very stable when playing hammer, can not produce to shake up and down and swing.
When adopting Fig. 5 and this dual mode of Fig. 6, when hammer stem 4 freely falls by gravity, the hydraulic oil release of piston 7 upper cylinder halfs, return fuel tank non-resistance, form zero pressure in the rubber hose, when hammer stem 4 rises, hydraulic oil dashes the rubber hose that rises quickly with sudden force, make that the rubber tube spring is very high, long-term such one a loose bullet, rubber tube is easy to break.So adopt electromagnetic valve 30 to switch, hydraulic oil turn-on accumulator 31 is made for the rubber hose of pressure oil is for a long time in running order do not relax one's efforts, so rubber hose has not just been bounced.Accumulator can also be when hammer stem 4 rises makeup energy.
