The invention provides a rail-changeable portal crane, which comprises a portal frame, a cart traveling mechanism, a crane carriage and an electrical part, and is characterized in that the traveling direction of the cart traveling mechanism is flexibly and conveniently changed through the structure of a traveling mechanism rotating device, so that the portal crane can be used on different working rails; the use range of the portal crane is expanded; according to the invention, the groove structure is arranged at the bottom end of the shell of the traveling mechanism, so that the derailment trend can be corrected in time through the groove structure when the traveling wheel of the cart has the derailment trend; the bolt lock mechanism is arranged on the advancing mechanism rotating device and used for limiting rotation of the cart advancing mechanism relative to the track in the advancing process of the portal frame, and the situation that cart advancing wheels fall off the track or deviate and gnaw the track due to rotation of the cart advancing mechanism relative to the track is avoided.

    本发明提供一种可变轨门式起重机,包括:门架、大车行进机构、起重小车和电气部分,其中,本发明通过行进机构旋转装置结构灵活便捷地改变了大车行进机构的行进方向,由此使门式起重机可在不同工作轨道上使用,扩大了门式起重机的使用范围;本发明在行进机构壳体底端设置凹槽结构,可在大车行进轮有掉轨趋势时通过这一凹槽结构及时纠正掉轨趋势;本发明在行进机构旋转装置上设置有栓锁机构,用以限制大车行进机构在门架行进过程中产生相对于轨道的旋转,避免大车行进轮因大车行进机构相对于轨道的旋转发生掉轨或跑偏啃轨。
