Automatic variable-frequency multiple-empty-hitting-prevention hydraulic breaking hammer
The invention relates to the technical field of quartering hammers, in particular to an automatic frequency conversion multiple anti-idling hydraulic quartering hammer which comprises a front cylinder body, a middle cylinder body, a rear cylinder body, a reversing valve and a piston, the front cylinder body, the middle cylinder body and the rear cylinder body are sequentially connected end to end, and the reversing valve is installed on the outer side of the middle cylinder body. The piston is movably arranged in the front cylinder body, the middle cylinder body and the rear cylinder body, an oil outlet groove, a buffering oil groove, a high-pressure oil groove, an anti-idling oil groove, a high-low pressure conversion oil groove, an oil drainage groove and a high-pressure oil groove are sequentially formed in the middle cylinder body in the direction from the front cylinder body to the rear cylinder body, and the buffering oil groove is used for preventing the piston from making direct contact with the middle cylinder body; when the drill rod is not compacted on a crushed object, the crushing hammer cannot be started (direct idle beating is prevented); in the working process, if the phenomenon of idle beating occurs, the hydraulic breaking hammer automatically stops working (preventing idle beating in the working process); the technical problems that in the prior art, a hydraulic breaking hammer is idle in hitting and the hitting power cannot be automatically adjusted are solved.
本发明涉及破碎锤技术领域，具体涉及一种自动变频多重防空打液压破碎锤，该破碎锤包括前缸体、中缸体、后缸体、换向阀和活塞，前缸体、中缸体、后缸体依次首尾连接，换向阀安装在中缸体的外侧，活塞活动设置在前缸体、中缸体和后缸体的内部，中缸体内沿前缸体至后缸体方向依次设置有出油槽、缓冲油槽、高压油槽、防空打油槽、高低压转换油槽、泄油槽和高压油槽，所述缓冲油槽用于防止活塞和中缸体直接接触；当钎杆没有被压实到被破碎物体上时破碎锤不能启动(防止直接空打)；在工作过程中若出现“空打”现象液压破碎锤自动停止工作(防止工作过程空打)；解决了现有技术中液压破碎锤存在空打以及不能自动调节打击力的技术问题。
