The invention discloses a multi-portal-leg semi-portal frame type frame and equipment thereof, the multi-portal-leg semi-portal frame type frame comprises a plurality of rigid portal legs, a plurality of main beams and a plurality of end beams, four tracks for trolley passing are arranged on the top end beam to form a four-track two-channel structure, and the end beams are arranged among the main beams in parallel to form a multi-portal-leg semi-portal frame type frame. A plurality of layers of parallel main beam and end beam frames are formed, the end beams and the main beams on the topmost end layer and the tail end layer in the multi-layer frame are in rigid connection, the upper portions of the end beams and the main beams on the middle layer are connected in a hinged mode through knuckle bearings, and the lower portions of the end beams and the main beams are connected through hinges. The rigid door legs are correspondingly and fixedly connected with the main beams respectively, deformation or inconsistent deformation of the corresponding main beams when the trolley is in a no-load state and a full-load state is avoided, and meanwhile distortion and deformation of the middle end beams are avoided. The double-trolley multi-mechanism multi-lifting-point working condition can be met, the problem between double-trough collaborative feeding and high efficiency is solved, and the field process requirement is met.
本发明公开了一种多门腿半门架式框架及其设备,包括多根刚性门腿、多个主梁和多个端梁,并在顶部端梁上设置有四根用于小车通行的轨道,形成四轨道两通道结构,且多个端梁平行设置于多个主梁之间,形成多层互相平行的主梁和端梁框架,且在多层框架中位于最顶端和最末端两端层的端梁与主梁之间刚性连接,位于中间层的端梁与主梁之间的上部采用关节轴承铰接连接,下部采用铰链进行连接,多根刚性门腿分别与多根主梁之间对应固定连接,避免小车空载和满载时对应主梁发生变形或发生的变形量不一致,同时避免中间端梁发生扭曲变形。能够满足双小车多机构多吊点工况,解决双料槽协同加料与高效率之间的问题,满足了现场工艺要求。
