Bushing type hydraulic breaking hammer
The invention relates to a bushing type hydraulic breaking hammer. The bushing type hydraulic breaking hammer comprises an upper cylinder block, a middle cylinder block and a lower cylinder block, wherein a striking piston can be mounted in a through cavity formed by the upper cylinder block, the middle cylinder block and the lower cylinder block; the striking piston comprises a buffer section, alarge-diameter section and a guide sleeve section which are integrally formed; the middle cylinder block comprises a guide sleeve section, a large-diameter section, a buffer section and a lower oil seal section; the inner diameters of the guide sleeve section, the large-diameter section and the buffer section are sequentially reduced; buffer oil seal sleeves are mounted on the inner walls of the buffer section and the lower oil seal section; the buffer oil seal sleeves are used for guiding and supporting the striking piston and sealing hydraulic oil at the lower part of the middle cylinder block; and each buffer oil seal sleeve comprises a buffer section sleeve and a lower oil seal section sleeve which are integrally formed or separately manufactured. According to the bushing type hydraulic breaking hammer, the cost is saved by replacing the buffer oil seal sleeves, and unnecessary waste is avoided.
本发明涉及一种镶套型液压破碎锤，包括上缸体、中缸体、下缸体，所述上缸体、中缸体、下缸体形成的贯通腔体内可安装打击活塞；所述打击活塞包括一体成形的缓冲段、大径段、导套段，所述中缸体包括导套段、大径段、缓冲段、下油封段，且所述导套段、大径段、缓冲段的内径依次减小，所述缓冲段及下油封段内壁上安装缓冲油封套，所述缓冲油封套实现对打击活塞的导向和支撑及对中缸体下部液压油的密封。所所述缓冲油封套包括一体成型或者分体制成的缓冲段套和下油封段套。本发明通过更换缓冲油封套来节约成本，避免不必要的浪费。
