Abstract
A dynamic reversing power compensatory device of a hydraulic quartering hammer comprises a valve body, a reversing valve spool and a reversing valve sleeve, wherein the reversing valve spool and the reversing valve sleeve are arranged in the valve body, and a constant pressure cavity is arranged between the valve body and the reversing valve sleeve. The upper portion of the constant pressure cavity is communicated with a dynamic oil cavity through a constant pressure hole, a dynamic valve spool is arranged in the dynamic oil cavity, a groove is formed in an outer circle of the dynamic valve spool, a spring is arranged on the back of the dynamic valve spool, a valve base is arranged on the back of the spring, and a discharging and recharging oil hole is formed in a side of the spring. The problems that a reversing passageway is blocked and the like due to the fact that reversing of a reversing valve sleeve of an existing hydraulic quartering hammer lags are solved, the reversing valve is enabled to be sensitive and stable, oil temperature is reduced effectively, work efficiency of the hydraulic quartering hammer is improved greatly, the requirements of mechanical parts and sealing elements are lowered, the service life is prolonged, and precious energy is saved.
Description
Technical field
The utility model relates to a kind of hydraulic breaking hammer, refers in particular to a kind of hydraulic breaking hammer and dynamically commutates and mend the merit device.
Background technique
At present, the selector valve of hydraulic breaking hammer all is the commutation that is determined selector valve by the commutation position of piston both at home and abroad, but because the broken object crushibility of hydraulic breaking hammer does not wait, platform is exerted pressure with the echo of the object that is broken all dynamically, so the piston in actual conditions is not worked in desirable travel range basically, the return that causes selector valve to lag behind and do not wait, cause that oil-feed and drainback passage narrow down, make hydraulic oil seriously push heating, cause having acting to descend, and harsher to mechanical parts and Sealing requirement, cause descend working life, the hydraulic oil volatilization, in advance aging.
Summary of the invention
The purpose of this utility model is to solve the problems such as return that existing hydraulic breaking hammer change-over valve lags behind and do not wait, provide a kind of hydraulic breaking hammer dynamically to commutate and mend the merit device, it can realize selector valve stable commutation and resetting dynamically in the different travel range of piston, mend merit when reaching the little stroke of piston, oil temperature is identical with temperature under the perfect condition, and mechanical parts and Sealing requirement are reduced, and increases the service life, raise the efficiency the energy of saves valuable breakthroughly.
For achieving the above object, the solution that the utility model is taked is: a kind of hydraulic breaking hammer dynamically commutates and mends the merit device, it comprises valve body, changeover valve core, commutation valve pocket, and dress changeover valve core and commutation valve pocket in the valve body have a constant voltage chamber between valve body and the commutation valve pocket, top, constant voltage chamber is communicated with dynamic oil pocket by a constant voltage hole, dynamically in the oil pocket a dynamic spool is arranged, dynamically the spool cylindrical has groove, and dynamically there is spring the spool back, there is valve seat the spring back, and the spring side is unloaded the repairing hole.
Selector valve is enclosed between valve body and the changeover valve core with reciprocating motion of the pistons, and when the constant voltage chamber volume between valve body and the commutation valve pocket reduced, the hydraulic oil the constant voltage chamber in was discharged to oil return by constant voltage hole, dynamically oil pocket, dynamic spool from unloading the repairing hole.If in this process in the constant voltage hole hydraulic oil be squeezed, pressure raises, dynamically spool backs down spring and increases path, and the commutation valve pocket is resetted rapidly, commutation hole and changeover valve core spill port remain to rapidly desirable latus rectum before the valve body.It has solved the problems such as commutation path that existing hydraulic breaking hammer causes because selector valve cover commutation lags behind is not smooth, make selector valve sensitive reversing and stable, effectively reduced oil temperature, greatly improved the mechanical efficiency of hydraulic breaking hammer, mechanical parts and Sealing requirement are reduced, increase the service life the energy of saves valuable.
