Described piling joint mechanism comprises joint 2, anvil iron 3, flat key 4, positioning sleeve 5 and fairlead 6; Described joint 2 is connected by bolt 22 with the cylinder body 7 of beater mechanism, the endoporus of joint 2 is divided into epicoele and cavity of resorption by dividing plate, described flat key 4, fairlead 6 and positioning sleeve 5 are located in the epicoele of joint 2, fairlead 6 is positioned at the top of positioning sleeve 5, anvil iron 3 is positioned at cavity of resorption, and the centre bore that passes on the dividing plate is connected by flat key 4 with positioning sleeve 5.Be provided with cushion pad 24 between described fairlead 6 and the positioning sleeve 5, can reduce the impact of impacting rebound impact mechanism.Face relative with impact piston 21 on the described anvil iron 3 is provided with pallet 25, the effect that pallet 25 has buffering and transmits impact stress.Be provided with the second cushion pad 25 between anvil iron 3 and the dividing plate, the soffit of anvil iron 3 is provided with dolly 27, and dolly 27 has the effect of transmitting impact stress and protecting pile body 1 head.
As shown in Figure 3, wherein solid arrow represent High-Pressure Water to, dotted arrow represent low pressure water flow to.Start successively the first motor 35 and the second motor 32, the water of water tank 32 inside is transformed into High-Pressure Water through behind the filter 34 under centrifugal water pump 35 and booster water pump 36 two-stage pressurizations, and by reducing valve 29, is adjusted to specified hydraulic pressure.After pulling start-stop valve 28, water under high pressure just enters in the left high pressure chest b of valve from water inlet, again along cylinder body 7 water flow inside passages, flows to respectively accumulator 8 and piston ante-chamber i.Under water under high pressure drove, 21 periods of motion of impact piston were divided into backhaul acceleration, backhaul deceleration and stroke and accelerate three phases.Impact the 3 backward upper bounce-backs of anvil iron as the motion starting point take impact piston 21, because the right permanent high pressure chest e of valve is by valve opening K 1, flat valve center water channel K 2Left high pressure chest b communicates with valve, is full of all the time water under high pressure, and the left alternating cavity a of valve is by stroke signal hole, hole K 4With backwater hole K 5D communicates with the valve backwater cavity, is low-pressure water in the chamber, so that flat valve 11 is under the right permanent high pressure chest e High Pressure of valve is the next, makes piston back cavity g communicate low pressure water flow recovery tank 32 with valve backwater cavity d.Impact piston 21 is upwards done backhaul accelerated motion under piston ante-chamber i water under high pressure drives.
As shown in Figure 4, as impact piston 21 backhauls control limit B 1Cross returned signal hole K 3After, water under high pressure is just through returned signal hole K 3Enter the left alternating cavity a of valve, because the left alternating cavity a of valve compression area is greater than the right permanent high pressure chest e of valve, so that flat valve 11 switches to fast is upper, make that the path of g and valve backwater cavity d is cut off after the plunger shaft, water under high pressure enters piston ante-chamber i and piston back cavity g simultaneously at this moment.Because piston back cavity g compression area is greater than piston ante-chamber i, resultant direction is downward, and under effect of inertia, impact piston 21 also can continue to move upward until speed is zero, then does stroke accelerated motion downwards.
During impact piston 21 stroke movements, as control limit B 2Cross stroke signal hole K 4After, the left alternating cavity a of valve communicates with valve backwater cavity d again, causes the left alternating cavity a of valve hydraulic pressure to descend rapidly, and flat valve 11 is got back to the next fast.This moment, impact piston 21 impacted anvil iron 3, and stroke accelerated motion finishes, impact piston 21 bounce-backs, and beginning is circulation next time.
21 backhaul boost phase initial stages of impact piston and backhaul decelerating phase, when outside input flow rate greater than impactor system consumption amount, the water under high pressure that accumulator 8 storage is unnecessary; And in backhaul boost phase later stage and stroke stage, the impactor system consumption is during greater than outside input flow rate, accumulator 8 just discharges water under high pressure satisfying the demand of flow system flow, so accumulator 8 can reduce flowed fluctuation and impact to slow down hydraulic pressure, improves capacity usage ratio.Above-mentioned is that hydraulic impactor externally continues under the driving of input current, and impact piston 21 and flat valve 11 are by the travel feedback signal, and automatic reverse and mutual control transform water pressure energy the process of piston kinetic energy.
Impact piston 21 is after impacting anvil iron 3, impact piston 21 speed reduce to zero again bounce-back from maximum rapidly, and anvil iron 3 is owing to limited and can't move by flat key 4 at impact direction, thereby produce stress in striking face generation compressive strain, and pass to pile body 1 and make it overcome soil layer resistance and frictional force, make and self sink to gradually soil layer.About the about 40Hz of impact piston 21 frequency of impacts, the high-frequency percussion meeting causes that pile body 1 and surrounding soil particle thereof vibrate together, even covibration occurs, and has reduced like this adhesion stress of soil particle, makes the pile body 1 easier soil layer that sinks to.
