Automatic frequency conversion nitrogen explosion type hydraulic breaking hammer
The invention discloses an automatic frequency conversion nitrogen explosion type hydraulic breaking hammer, which relates to hydraulic equipment and comprises a shell, a front lining plate, a rear lining plate, an upper cylinder body, a middle cylinder body with a square cross section, a lower cylinder body, a whole body bolt, a reversing valve, a piston, a frequency conversion valve, an energy accumulator and a drill rod, an energy storage device, an oil inlet flange connector and an oil return flange connector are arranged on the side face of the middle cylinder body, the reversing valve comprises a reversing valve shell, a reversing valve element and a reversing valve deck, and the frequency conversion valve comprises a frequency conversion valve sleeve, a frequency conversion valve element, a frequency conversion gland and a frequency modulation nut. According to the automatic frequency conversion nitrogen explosion type hydraulic breaking hammer, a brand new frequency conversion valve replaces a traditional reversing valve, the striking frequency can be automatically adjusted, the trouble of manually adjusting frequency conversion striking is omitted, and practicability and high efficiency are achieved; the crushing requirements of soft and hard to-be-beaten surfaces are met; in the brand new design, the cylinder body is of a cube structure, oil ways distributed in the axis direction are diversified, and adjustment of various striking frequencies can be adapted.
本发明公开了一种自动变频的氮爆式液压破碎锤，涉及液压设备，包括外壳、前衬板、后衬板、上缸体、横截面呈正方形的中缸体、下缸体、通体螺栓、换向阀、活塞、变频阀、蓄能器和钎杆，上缸体上部设置有换向阀和变频阀，侧面设置有储能器、进油法兰接口和回油法兰接口，换向阀包括换向阀壳、换向阀芯、换向阀盖，变频阀包括变频阀套、变频阀芯、变频压盖、调频螺帽，中缸体轴线方向分布若干个油路，该自动变频的氮爆式液压破碎锤以全新变频阀取代传统换向阀，可自动调整打击频率，省去人力手动调节变频打击的麻烦，实用高效；适用于有软有硬的待打击表面破碎需求；全新设计中缸体为正方体结构，轴线方向分布油路多样，可以适应多种打击频率的调节。
