In: the upper end of upper hammer is connected with upper oil-way integrated block, and the lower end of upper hammer is connected with lower oil-way integrated block, the inner cavity of upper hammer
Center is provided with cylinder body, and is symmetrically arranged with array piston accumulator in the surrounding of cylinder body.
The piston accumulator is connected with the epicoele of cylinder body setting by pipeline.
Oil cylinder ectosome is provided on the outside of the cylinder body, oil cylinder ectosome is coated with cylinder body, oil cylinder ectosome and cylinder body
Between for configuring various oil pipes and power supply line.
The lower hammer includes hammer core, piston rod and hammer body shell；The lower end of the upper end and piston rod of hammering core into shape is fixed
It is connected, and it is hammered into shape and is provided with buffing pad and joint bearing block between core and the connection of piston rod；It stretches the upper end of the piston rod
Enter in the cylinder body into upper hammer.
A circle wear rib is provided between the hammer core and hammer body shell, it is solid that the outer wall of hammer body shell is fixedly installed with hammer body
Reservation, and cushion is provided between hammer body shell and hammer body fixing seat.
The beneficial effects of the utility model embodiment is: compared with prior art, the utility model passes through in cylinder body
Around be symmetrically distributed with the accumulator of array size equilibrium, during piling can equilibrium effectively absorb shock pulse,
To cushioning effect；Ensure to mention hammer and there are enough screen resiliences during dropping hammer, to meet the required energy of piling and strike
Precision and dynamics.

Specific embodiment
As shown in Figure 1 to Figure 3, double-action hydraulic pile hammer is made of upper hammer, intermediate connecting body 13 and lower hammer；
The intermediate connecting body 13 is respectively fixedly connected with upper hammer and lower hammer by flange；The upper end of upper hammer is connected with oil circuit
Integrated package 1, the lower end of upper hammer are connected with lower oil-way integrated block 5, and the inner cavity center of upper hammer is provided with cylinder body 3, and
Array piston accumulator (2,14) are symmetrically arranged in the surrounding of cylinder body 3.Oil-way integrated block 1 includes that fuel feed pump connects on this
Connector, oil return pipe connector and connector of each electric kind of power supply line etc.；Lower oil-way integrated block 5 also include fuel feeding pipe connector,
The connector etc. of oil return pipe connector and each electric kind of power supply line.
The piston accumulator (2,14) is connected with the epicoele of cylinder body 3 setting by pipeline, and piston type stores
Can in device it is canned in advance enter nitrogen, when the piston in cylinder body 3 rises, intracavitary hydraulic oil flows to piston respectively on cylinder body 3
It in formula accumulator, and is flowed into the hydraulic oil in piston accumulator and further compresses nitrogen in it, risen to piston rod
When setting height, the nitrogen of compression is sprung back, and is again flowed into cylinder body using the hydraulic oil of reflux, to push under piston rod
It moves, using the booster action of array piston accumulator, makes to mention hammer or drop hammer more steady.
