In order to achieve the above object, the utility model is realized through following technological means.
A kind of novel hydraulic quartering hammer; It comprises impact bar, front-bank rotor housing, accumulation of energy assembly, plug, middle cylinder body, rear-bank rotor housing, outlet valve, reversal valve, nitrogen valve, plunger; It is characterized in that: in front-bank rotor housing, be provided with impact bar; Be provided with external bushing, round pin, first rubber stopper, circlip at the front-bank rotor housing front end; Be provided with first latch, second rubber stopper, second latch, grease nipple at the middle part of front-bank rotor housing, in the rear end of front-bank rotor housing, be provided with neck bush, be provided with outlet valve in the front-bank rotor housing rear end; Middle cylinder body is provided with that accumulation of energy assembly, plug, fabrication hole are stifled, fuel feed hole, spill port, in middle cylinder body, is provided with plunger, is provided with reversal valve at middle rear end of the cylinder block, behind reversal valve, is provided with 0 type circle; Rear-bank rotor housing is provided with nitrogen valve; Four entire body bolts are fixedly connected front-bank rotor housing, middle cylinder body, rear-bank rotor housing through the nut at its two ends in inside.
Operating principle:
A kind of novel hydraulic quartering hammer; This quartering hammer injects hydraulic oil by fuel feed hole, and the force plunger of generation moves to rear-bank rotor housing, the nitrogen in the compression rear-bank rotor housing; When plunger rises to certain position; The inner spool of reversal valve begins to move backward, and when the inner spool of reversal valve moved to the top, the upper and lower cavity of plunger was communicated with through the hole of reversal valve; The force plunger that compressed nitrogen expansion produced in the rear-bank rotor housing hits impact bar; When plunger dropped to certain position, the inner spool of reversal valve was displaced downwardly to the bottom, and hydraulic oil gushes through spill port; Like this; Go round and begin again, the plunger of quartering hammer can move back and forth, and hits the driving impact bar and carries out fragmentation work.
The utility model mainly has following beneficial effect:
1, traditional welded construction has been cancelled in the shutoff of this quartering hammer fabrication hole, adopts the end face plug to add O type circle and seals, and can effectively guarantee sealing effectiveness and convenient disassembly;
2, between the plunger of this quartering hammer and the cylinder body through the adjustment of fit dimension, can guarantee after variations in temperature, to let out minimum in the hydraulic breaking hammer, avoid the generation of scuffing of cylinder bore locking fault;
3, this quartering hammer has increased the hydraulic energy-accumulating apparatus, has stablized the hydraulic pressure of pipe line oil pressure on the one hand, has increased the hitting power of hydraulic breaking hammer on the other hand, has improved operating efficiency.
