Middle cylinder body structure of hydraulic breaking hammer
The invention provides a middle cylinder body structure of a hydraulic breaking hammer, and relates to the technical field of hydraulic breaking hammers, the structure comprises a middle cylinder body and a piston, and piston fixing parts in clearance fit with the middle cylinder body are arranged on the inner circumferential walls of the two ends of the middle cylinder body in the axis direction of the middle cylinder body; an auxiliary protection part on a piston fixing part is arranged on the inner side of a fixing part body through die-casting forming by adopting polyether-ether-ketone, a piston can be in contact friction with a supporting ring installed on the inner side wall of the auxiliary protection part in the eccentric state firstly, and when the radial supporting force of the supporting ring is compressed or abraded to be zero, the piston starts to make contact with the auxiliary protection part; the auxiliary protection part can provide long-term continuous radial supporting force for the piston, and abrasion to the piston is avoided. When the breaking hammer is seriously deflected, the piston is continuously subjected to eccentric force and is seriously eccentric at a certain point, the piston positioning part plays a role, the piston positioning part taking polyether-ether-ketone as a main material can effectively protect the middle cylinder body, an inner cavity of the middle cylinder body is prevented from being scratched, and the service life of the breaking hammer is prolonged.
本发明提供了一种液压破碎锤的中缸体结构，涉及液压破碎锤技术领域，该结构包括中缸体及活塞，中缸体沿其轴线方向的两端的内周壁上设有与其间隙配合的活塞固定部；活塞固定部上的辅助保护部采用聚醚醚酮通过压铸成型设于固定部主体内侧，活塞在偏心状态下能先与安装在辅助保护部内侧壁上的支撑环接触摩擦，待支撑环的径向支撑力被压缩或磨损清零时，活塞开始与辅助保护部接触；辅助保护部能对活塞提供长期连续的径向支撑力，避免对活塞的磨损。破碎锤出现严重偏打时，活塞连续受到偏心力作用导致在某一点偏心严重，此时活塞定位部发挥作用，以聚醚醚酮为主材的活塞定位部能有效起到保护中缸体作用，防止中缸体内腔划伤，增加破碎锤的使用寿命。
