Technical field
The present invention relates to impact vibration equipment technical fields, and in particular to a kind of all-hydraulic integrated impact device.
Background technology
Hydraulic breaking hammer can be widely applied to the construction fields such as metallurgy, mine, railway, highway, building, to hard objects such as
Rock, cement pavement, aging blocks etc. such as are exploited, are crushed, being removed at the operations, can also be by converting drill steel, for riveting, removing
Operations specifics, the purposes such as become rusty, vibrate, tamping, driving piles are very extensive.It reaches a conclusion after weighing a matter and has quickly grown since city, have three generation products so far,
That is full hydraulic, liquid gas association type and nitrogen-inflating hydraulic hammer.
Seen three generations's hydraulic breaking hammer product currently on the market, basic structure are by middle cylinder body, piston, preceding cylinder
The compositions such as body, drill steel, reversal valve, rear-bank rotor housing, side plate.It is coupled between middle cylinder body, front-bank rotor housing, rear-bank rotor housing three by stay bolt
One, is coupled through side plate to realize between hydraulic breaking hammer hammer body and host, and side plate and hammer body are also by side plate spiral shell
Bolt is coupled integral.Since hydraulic breaking hammer is to complete crushing operation with high-frequency percussion vibration at work, high frequency punching
Hitting vibration can often cause the stay bolt of hydraulic breaking hammer and side plate bolt to loosen or even be present with the disconnected of stay bolt and side plate bolt
It splits, so that hydraulic breaking hammer breaks down, it has to be stopped, influence being smoothed out for engineering construction, brought to user
Economic loss.Meanwhile the design that reversal valve has with middle cylinder body is integrated, and is known as built-in valve, has plenty of separated, is known as outer
Valve is put, but is not and piston coaxial, causes hydraulic breaking hammer appearance and size bigger than normal, and amount of parts is on the high side, raw material
The negative consequences such as expense increases, and processing cost increases.

Movement.
Further, be sleeved in the piston it is axial at least provided with a stepped hole, using at step as boundary, will be in piston
Set is divide into upper part and lower part, and piston is divided into two chambers up and down using the border that top and the bottom are covered in piston as boundary, and upper chamber is by living
Set, valve pocket, spool, mandril, piston rear enclosure, hammer body are formed in plug, piston；Lower chambers by piston protheca, piston, piston cover,
Hammer body is formed.
Further, accumulator is installed on the hammer body.
Further, the accumulator is bolted on hammer body.
Further, the drill steel set is bolted on hammer body.
(3) advantageous effect
Beneficial effects of the present invention：A kind of all-hydraulic integrated impact device integrative design, is not only avoided that bolt looseness
And make hydraulic hammer failure that cannot work, the failure rate of hydraulic breaking hammer is reduced, improves work efficiency；It is compact-sized, zero
Number of packages amount is few, reduces the usage amount of metal material, and the consumption of raw material reduces, and the processing cost of product reduces；Impactor machine
High pressure accumulator is designed with it, is reduced influence of hydro pulse when hydraulic hammer works to host hydraulic system, is carried simultaneously
The high hitting power of hydraulic breaking hammer.
