The invention relates to the technical field of cranes, and relates to a sliding shoe device of a large series circular track crane, in particular to a crane sliding shoe capable of automatically inserting and pulling a pin. The crane sliding shoe comprises a sliding shoe beam, push-pull trolleys, sliding rails, a track beam and track baffles, the two sliding rails are arranged on the track beam in parallel, at least one group of push-pull trolleys and the sliding shoe beam are arranged on the sliding rails in a sliding manner, the push-pull trolleys are connected with the sliding shoe beam through an oil cylinder, and the plurality of track baffles are evenly arranged on the outer sides of the two sliding rails. According to the crane sliding shoe, the pressure of the contact surface between a running mechanism and the track is reduced, the action time of the running mechanism is shortened, and the working efficiency of a crane is improved.

    本发明涉及起重机技术领域,涉及到一种大型系列环轨起重机的滑靴装置,具体涉及一种自动插拔销的起重机滑靴,包括:滑靴梁、推拉小车、滑轨、轨道梁和轨道挡板;所述滑轨为两条,平行设置在轨道梁上;所述滑轨上滑动设置至少一组推拉小车和滑靴梁;所述推拉小车与滑靴梁通过油缸连接;两条滑轨外侧均匀设置多个轨道挡板。本发明减少了运行机构与轨道之间接触面的压力,缩短了运行机构动作时间,提高了起重机工作效率。
