Abstract
A kind of hydraulic breaking hammer dynamically commutates and mends merit device, it comprises valve body, changeover valve core, commutation valve pocket, changeover valve core and commutation valve pocket is filled in valve body, have a constant voltage chamber between valve body and commutation valve pocket, top, constant voltage chamber is communicated with dynamic oil pocket by a constant voltage hole, has a dynamic spool in dynamic oil pocket, dynamic spool cylindrical has groove, have spring after dynamic spool, have valve seat after spring, repairing hole is unloaded in spring side.It solve existing hydraulic breaking hammer because of the selector valve cover commutation problems such as the delayed commutation path caused is not smooth, make selector valve sensitive reversing and stablize, significantly reduce oil temperature, substantially increase the mechanical efficiency of hydraulic breaking hammer, mechanical parts and Sealing requirement are reduced, increase the service life, save the valuable energy.
Description
Technical field
The present invention relates to a kind of hydraulic breaking hammer, refer in particular to a kind of hydraulic breaking hammer and dynamically commutate and mend merit device.
Background technique
At present, the selector valve of domestic and international hydraulic breaking hammer is all the commutation being determined selector valve by the commutation position of piston, but due to the broken object crushibility of hydraulic breaking hammer not etc., platform is exerted pressure with the echo of object to be broken all dynamically, so the piston in actual conditions does not work substantially in desirable stroke range, cause the delayed and return not etc. of selector valve, oil-feed and drainback passage is caused to narrow, hydraulic oil severe crush is generated heat, cause having acting to decline, and require harsher to mechanical parts and Sealing, cause decline working life, hydraulic oil volatilizees, aging in advance.
Summary of the invention
The object of the invention is to solve the problems such as the delayed and return not etc. of existing hydraulic breaking hammer change-over valve, there is provided a kind of hydraulic breaking hammer dynamically to commutate and mend merit device, it can realize selector valve commutation stable in the stroke range that piston is different and dynamic reset, merit is mended when reaching the little stroke of piston, oil temperature is identical with temperature ideally, mechanical parts and Sealing requirement is reduced, increases the service life, raise the efficiency breakthroughly, save the valuable energy.
For achieving the above object, the solution that the present invention takes is: a kind of hydraulic breaking hammer dynamically commutates and mends merit device, it comprises valve body, changeover valve core, commutation valve pocket, fills changeover valve core and commutation valve pocket, have a constant voltage chamber between valve body and commutation valve pocket in valve body, top, constant voltage chamber is communicated with dynamic oil pocket by a constant voltage hole, have a dynamic spool in dynamic oil pocket, dynamic spool cylindrical has groove, has spring after dynamic spool, have valve seat after spring, repairing hole is unloaded in spring side.
Selector valve is enclosed within reciprocating motion of the pistons between valve body and changeover valve core, and when the constant voltage chamber volume between valve body and commutation valve pocket reduces, the hydraulic oil in constant voltage chamber, by constant voltage hole, dynamically oil pocket, dynamically spool, is discharged to oil return from unloading repairing hole.If in constant voltage hole, hydraulic oil is squeezed in this process, pressure raises, and dynamic spool backs down spring and increases path, and commutation valve pocket is resetted rapidly, and before valve body, commutation hole and changeover valve core spill port remain to rapidly desirable latus rectum.It solve existing hydraulic breaking hammer because of the selector valve cover commutation problems such as the delayed commutation path caused is not smooth, make selector valve sensitive reversing and stablize, significantly reduce oil temperature, substantially increase the mechanical efficiency of hydraulic breaking hammer, mechanical parts and Sealing requirement are reduced, increase the service life, save the valuable energy.
