Middle cylinder component of hydraulic breaking hammer
The invention discloses a middle cylinder component of a hydraulic breaking hammer. The middle cylinder component of the hydraulic breaking hammer comprises a piston 1, a middle cylinder body 2, a piston ring 3, a sealing piece 4 and a reversing valve 5; a fifth piston rod sealing piece groove 25, a second oil return groove 26, a high-pressure oil groove 27 and a sixth piston rod sealing piece groove 28 are additionally arranged on an original sealing structure which is matched with a piston head in an inner hole of the middle cylinder body 2; an oil feeding groove 36 is additionally formed in an original inner hole sealing structure of the piston ring 3; a radial through hole a is formed in the oil feeding groove 36 and communicated with an oil inlet groove 12 formed in the piston ring; an oil way 13 is arranged on the middle cylinder body 2 and communicated with the high-pressure oil groove 27 and the oil inlet groove 12; and meanwhile the oil way 13 is externally connected with a high-pressure oil supply port 14. According to the invention, the high-pressure oil supporting effect of the front section and the rear section of the piston is enhanced, so that the problems that the piston and the cylinder body are prone to strain, oil leakage and the like in the initial working stage of the breaking hammer are effectively solved.
本发明一种液压破碎锤中缸部件，所述中缸部件包括：活塞1、中缸体2、活塞环3、密封件4和换向阀5；在所述中缸体2内孔与活塞头配合的原有密封结构上增设第五道活塞杆密封件沟槽25，第二道回油槽26、高压油沟槽27及第六道活塞杆密封件沟槽28；在所述活塞环3原有内孔密封结构中增设一道给油槽36，在所述给油槽36内设置一径向通孔a，与活塞环上设置的进油槽12连通；在所述中缸体2上设置一条油路13与高压油沟槽27和进油槽12连通，同时油路13外接高压油供油口14。本发明通过增强活塞前段和后段高压油支持作用，有效地解决了破碎锤在工作起始阶段易造成的活塞和缸体拉伤、漏油等问题。
