The invention discloses a plugging device for a quay crane lifting appliance upper frame and a lifting appliance. The plugging device comprises a plug assembly and a socket assembly. The plug assemblycomprises a plug shell, a traction electromagnet, a guide column, transverse compression springs, a longitudinal tension spring, positioning steel balls, partition plates, a conical column, a suckerand contact pins. The socket assembly comprises a socket shell, partition plate sleeve holes, a guide column sleeve hole, steel ball positioning holes and jacks. During butt joint, the positioning steel balls at the top end of the guide column fall into the steel ball positioning holes formed in the bottom end of the guide column sleeve hole and are extruded and fixed through the transverse compression springs, and self-locking is achieved. During separation, the traction electromagnet is powered on, the longitudinal tension spring contracts under traction of the traction electromagnet, the conical column is driven to operate along with the longitudinal tension spring, and the positioning steel balls are separated from the steel ball positioning holes to achieve unlocking. The self-lockingand automatic unlocking structure can avoid the fault of plug loosening caused by operation vibration. The contact pins are isolated by the partition plates according to electrical classification, sothat electromagnetic interference in operation is avoided.
本发明公开了一种用于岸桥吊具上架及吊具的插接装置,包括插头组件和插座组件,插头组件包括插头壳体、牵引电磁铁、导向柱、横向压缩弹簧、纵向张力弹簧、定位钢球、分隔板、锥形柱、吸盘和插针;插座组件包括插座壳体、分隔板套孔、导向柱套孔、钢球定位孔和插孔;对接时,导向柱顶端定位钢球落入导向柱套孔底端开设的钢球定位孔中,横向压缩弹簧将其挤压固定,实现自锁;分离时牵引电磁铁通电,纵向张力弹簧受牵引电磁铁的牵引而收缩,带动锥形柱跟随纵向张力弹簧运行,定位钢球从钢球定位孔中脱离实现解锁;这种自锁式和自动解锁式的结构,能够避免作业震动引起插头松脱的故障;且插针被分隔板按照电气分类进行隔离,避免了作业中的电磁干扰。
