nullThe end face of described piston 106 is connected to piston rod 108，Described piston rod 108 upwards passes described top cover labyrinth 103，Sealing means is adopted to be connected between described piston rod 108 with described top cover labyrinth 103，The end face of described piston 106 is stepped construction，The side of upper ladder 109 is provided with a upper sealing ring 110，The side of downstairs 111 is provided with a lower seal 112，The bottom end of described top cover labyrinth 103 is provided with the concave inward structure suitable with the stepped construction of described piston 106 end face，The sidewall of described inner core 105 is provided with at least one blow vent 113，When described piston 106 is positioned at the apical position place of described inner core 105，Described blow vent 113 described inner core 105 sidewall locations place between sealing ring 110 and described lower seal 112 on described；
The described bar 107 that hits includes hitting that a bar body 114 and being arranged on hits bar body 114 top hits a pole cap 115, a described bar body 114 that hits is set in the center axial position of described lower sealing cover 104 in a sealing fashion, described lower sealing cover 104 between described inner core 105 and described urceolus 102 offers air inlet 116, it is positioned in the described lower sealing cover 104 of described inner core 105 bottom and offers lower accent 117, described lower sealing cover 104 between described inner core 105 and described urceolus 102 is further opened with gas storage accent 118, it is in series with reversal valve 119 and fast-discharge valve 120 by air pipe between described gas storage accent 118 and described lower accent 117；
The described underface hitting a bar 107 is provided with holds stake cylinder 121, described in hold can place in stake cylinder 121 and hit, by described, the stake that a bar 107 hits；
Described top cover labyrinth 103 and lower sealing cover 104 are sealed to an air storing cavity between inside described urceolus 102 and outside described inner core 105, and described air storing cavity is connected with blow vent 113.
Described reversal valve 119 is two-bit triplet air operated reversing valve or two-bit triplet solenoid directional control valve.
As shown in Figure 4, described air-compressor set 2 includes engine 201, compressor 202 and air accumulator 203；Described engine 201 provides power for described compressor 202, and described compressor 202 is by compressed-air-storing to described air accumulator 203, and described air accumulator 203 is arranged on the top of described compressor 202 and described engine 201.
Described engine 201 is air-cooled petrol engine or water-cooled diesel engine.
Upper ladder 109 area of described piston 106 is 17 times of downstairs 111 area.
Embodiment:
Start air-compressor set 2 so that the pressure of air accumulator 203 reaches operating pressure, opens out the air-supplying valve on vapour tank, opens the intake valve of air storing cavity so that the pressure of air storing cavity also reaches the operating pressure needed.
nullNow reversal valve 119 is in the position to cavity of resorption supply，The air of air storing cavity supplies to epicoele and cavity of resorption simultaneously，Owing to the base area of piston 106 is more than the area of end face，Piston 106 rises，When piston 106 rise to upper sealing ring 110 be positioned at blow vent 113 above time，The end face of blow vent 113 and piston 106 separates，The upper portion pressurized area of piston 106 is only downstairs face (narrow anchor ring)，Now reversal valve 119 commutates，Close the gas circuit of air storing cavity and cavity of resorption，Fast-discharge valve 120 pressure release，The air of cavity of resorption is discharged by fast-discharge valve 120，When the air pressure pressure release of cavity of resorption is to when balancing with upper cavity pressure，Piston 106 starts to move down，When piston 106 is displaced downwardly to upper sealing ring 110 depressurization state，Namely go up sealing ring 110 to move to blow vent less than 113，Now piston 106 end face is subject to suddenly gross area artesian condition，Owing to the area of piston 106 end face and the area ratio of downstairs 111 are very big，Make piston 106 start explosion type to impact downwards，Form huge impact energy，Epicoele air inlet rapidly suddenly，Piston 106 is not only made to impact downwards，Have an active force upwards also can to piling head 1 housing simultaneously，Piling head 1 housing is made upwards to bounce，But owing to cavity of resorption is without pressure，And hit a bar 107 and stake relative to piling head 1 housing can be freely up and down，So stake will not be produced impact by the bounce-back of piling head 1 housing.Piston 106 quick washing is to hitting a bar 107 and by hitting a bar 107 driven pile (steel pipe), until running to lower dead center.The motion of this process is a compound motion, and while namely piston 106 hits driven pile bar 107, stake moves down, by the effect of epicoele inflation, piling head 1 housing is also moving up.When piston 106 runs to after bottom dead center, hit a bar 107 and also all stretch out.At this moment reversal valve 119 commutates, and fast-discharge valve 120 is forwarded to by exhaust condition and supplied state by reversal valve 119 to cavity of resorption, and cavity of resorption is inflated.Because piston 106 base area is more than top surface area, therefore piston 106 rises, and epicoele gas is pressed into air storing cavity, until piston 106 rises to top, starts subsequent cycle.
It should be noted that the ratio problem of the quality of piling head 1 housing and piston 106 mass.If the mass ratio of quality and the piston 106 of piling head 1 housing is sufficiently large, then, during the unexpected fast aeration of epicoele, piling head 1 housing bounce-back will be only small, and the speed of piston 106 undershoot then can be very big.If the quality of piston 106 is less than normal, although very big undershoot acceleration can be obtained, can impact kinetic energy also can reduce with the reduction of its quality；If the quality of oversize piston 106, then impact acceleration then can reduce, and the mass ratio of piling head 1 housing and piston 106 can be made to reduce simultaneously, and body bounce-back then can strengthen, impact piling effect.And if strengthen piling head 1 case weight, although the mass ratio of piling head 1 housing and piston 106 can be improved, but for portable mechanism, the machine that strengthens simply is heavily apparently not a good selection.So, reasonably select the mass ratio of piling head 1 housing and piston 106, reasonably determine complete machine equipment weight, make the bounce-back of machinery operationally body minimum, and the impact kinetic energy that can export is maximum, is the key of overall design.
This utility model is not limited to above-mentioned preferred forms; those of ordinary skill in the art can draw other various forms of products under enlightenment of the present utility model; no matter but in its shape or structure, do any change; every have same or like with the application like technical scheme, all fall within protection domain of the present utility model.
