Example Embodiment

[0020] The main components of the present invention:

[0021] 1. Crankcase 2. Eccentric wheel 3. Crankshaft 4. Eccentric wheel shaft 5. Gear 6. Cylinder block 7. Drill rod 8. Drill rod seat 11. Connecting rod 12. Connecting rod piston 13. Nitrogen chamber sealing sleeve 14. Nitrogen chamber 15. Piston 16. Piston lower chamber 17. Drill rod rear sleeve 18. Drill rod front sleeve 19. Valve plate 20. One-way valve 21. Throttle valve 22. Reversing valve 23. Accumulator 24. Piston upper chamber.

[0022] At the moment the hydraulic breaker is started, the piston 15 is at the farthest position (dead position) from the crankshaft under the action of nitrogen pressure in the nitrogen chamber 14. At this time, the lower piston chamber 16 and the hydraulic motor (used to drive the crankshaft 3 ) Through high pressure oil, under the action of the hydraulic motor through the crankshaft 3 connecting rod 11 and the action of the high pressure oil in the lower piston chamber 16, the piston 15 per...

Abstract

The invention discloses a hydraulic breaking hammer which comprises the components of a drill rod seat, a drill rod, a drill rod front sleeve, a drill rod back sleeve, a cylinder body, a piston, a nitrogen chamber sealing sleeve, a crankcase, a crankshaft, a connecting rod, a connecting rod piston, a motor, an eccentric wheel, a reversing valve, an energy accumulator, a valve plate, etc. One end, which is far from the drill rod, of the piston is dynamically connected with the eccentric wheel though the connecting rod, the crankshaft and the gear. One end of the crankshaft is connected with the motor. A sealed chamber for storing gas is arranged between the piston and the cylinder. The valve plate is mounted on the crankshaft. The hydraulic breaking hammer aims to settle problems of high difficulty in downward pressing a nitrogen explosion hammer, large hydraulic impact, incapability of stopping oil supply from a pump in a stroke period without oil consumption, no enough impact force caused by insufficient flow in a full-hydraulic hammer or a gas-liquid hammer, complicated structure, and large hydraulic impact force.

Description

technical field [0001] The invention relates to a special engineering machinery hydraulic tool, in particular to a hydraulic breaking hammer. Background technique [0002] The hydraulic hammer integrates control valves, actuators, accumulators and other hydraulic components. The control valve and the actuator are controlled by mutual feedback to automatically complete the reciprocating motion of the piston and convert the pressure energy of the liquid into the impact energy of the piston. At present, the piston return movement of the hydraulic hammer on the market is completed by hydraulic force, and the stroke movement of the piston can be divided into nitrogen explosion hammer, full liquid hammer and gas-liquid hammer according to the source of the force during the stroke. Three types. [0003] Working principle of nitrogen explosive hammer: Nitrogen explosive hydraulic hammer is referred to as nitrogen explosive hammer. The top of the piston is equipped with a nitrogen ...
