Central pivot device of mining machinery face shovel type excavator
The invention discloses a central pivot device of a mining machinery face shovel type excavator, which comprises an upper bearing sleeve, a C-shaped clamping plate, a stop key, a central pivot, a collecting ring pipe, a spherical washer, a pivot nut, an anti-loosening key, a lower bearing sleeve, a first pull rod and a second pull rod, the upper part of the central pivot is in clearance fit with a central hole of a rotary platform, and the lower part of the central pivot is arranged in a chassis copper sleeve; the C-shaped clamping plate and the stop key are fixed on the rotary platform, the spherical washer, the pivot nut and the anti-loosening key are arranged in the bottom frame and located on the periphery of the lower portion of the central pivot, the copper sleeve and the spherical washer are lubricated in a centralized mode through dry oil, and the collecting ring is installed in the central pivot in a penetrating mode through a pipe. A compressed air pipeline, a lubricating grease pipeline and a cable leading to the lower mechanism pass through a collecting ring pipe, and the lower portion of the collecting ring pipe is fixed to the bottom frame through a first pull rod and a second pull rod. The central pivot device is firm and reliable in connection and fixation, easy to overhaul and maintain and capable of preventing a compressed air pipeline, a lubricating grease pipeline, a cable and the like from being twisted.
本发明公开了一种矿用机械正铲式挖掘机的中央枢轴装置，包括上轴承套、C型卡板、止动键、中央枢轴、集电环用管、球面垫圈、枢轴螺母、防松键、下轴承套、第一和第二拉杆，中央枢轴的上部间隙配合于回转平台的中心孔、下部设置在底架铜套内，C型卡板和止动键固定在回转平台上面，球面垫圈、枢轴螺母和防松键设置在底架内并位于中央枢轴的下部外周，铜套和球面垫圈采用干油集中润滑，集电环用管贯通安装在中央枢轴内，通往下部机构的压缩空气管路、润滑油脂管路、电缆从集电环用管内通过，集电环用管下部通过第一和第二拉杆固定在底架上。该中央枢轴装置的连接固定牢固可靠，易于检修维护，并可避免压缩空气管路、润滑油脂管路、电缆等发生扭结。
