Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
It referring to Figures 1 and 2, is a kind of hydraulic pile hammer disclosed by the utility model, including hydraulic cylinder, hydraulic cylinder include cylinder
Body 1 and piston rod 2 are connected with the installation shell 3 being coated on outside piston rod 2 on cylinder body 1, and the lower end of piston rod 2 is provided with hammer seat
5, the lower end of hammer seat 5 is provided with tup 51 to contradict pile body 4 for impacting.When piling, impact that piston rod 2 generates hydraulic cylinder
Power passes to hammer seat 5 so that tup 51 carries out impact conflict to pile body 4, realizes the piling function of pile hammer.
Further, tup 51 is arranged in stage body, and tup 51 has big end and small end, and the big end of tup 51 is fixed on hammer seat
On 5, the small end of tup 51 is towards pile body 4 to contradict pile body 4 for impacting.Hammer 5 end face of seat is provided with abutting part around tup 51
52。
With reference to Fig. 3 and Fig. 4,3 lower end of shell is installed and is provided with noise reduction block 6, offered in noise reduction block 6 for 4 end of pile body
The card stake slot 61 of portion's clamping is provided with noise reduction cavity 63 in noise reduction block 6, and the inner wall of noise reduction cavity 63 is in the curved surface setting being bent outwardly
For increasing order of reflection of the noise in noise reduction cavity 63.Offered in noise reduction block 6 respectively with noise reduction cavity 63 and card stake slot 61
The punching groove 62 communicated is also provided with the Striker 64 for communicating with noise reduction cavity 63 and passing through for tup 51 in noise reduction block 6.Piling
When, tup 51 sequentially passes through Striker 64 and punching groove 62 and contacts at 4 end of pile body in card stake slot 61 to impact, due to occurring
The position that impact contradicts is located inside noise reduction block 6, and the noise that when conflict generates enters in noise reduction cavity 63, and passes through in noise reduction cavity 63
Multiple reflections are crossed to weaken noise.
Cladding is provided with acoustical cotton or aqueous damping coating on 6 outer wall of noise reduction block.The partial vibration of noise can pass through noise reduction
