The invention is applicable to the technical field of pipeline transportation, and provides a rail crane for pipeline transportation, which comprises a vehicle body and two parallel low-voltage power supply rails preset on the ground, the vehicle body comprises a lower vehicle frame and an upper vehicle frame, and a hydraulic lifting mechanism for driving the upper vehicle frame to lift is arranged between the lower vehicle frame and the upper vehicle frame. According to the rail travelling crane for pipeline transportation, the low-voltage power supply rail is arranged on the ground, the crane body walks on the ground rail, the rail and the conductive brush supply power to electrical equipment of the crane body, the hydraulic lifting mechanism controls the upper frame to ascend and descend to adjust the height, a common suspension type travelling crane is replaced, the crane body is low in height, climbing operation is not needed, and overhauling is convenient; the hydraulic lifting mechanism is used for achieving lifting, shaking cannot be generated in the lifting and walking processes, the pipeline is more stable, the problem that the pipeline shakes due to shaking of the vehicle body when a belt and a rope are driven to form lifting is solved, and potential safety hazards are reduced.
本发明适用于管道运送技术领域,提供了一种管道运送用轨道行车,包括车体和两个相互平行的预设于地面的低压供电轨道,所述车体包括下车架和上车架,所述下车架和上车架之间设置有驱动所述上车架升降的液压升降机构。该管道运送用轨道行车,通过在地面设置低压供电轨道,车体在地面轨道上行走,由轨道和导电刷为车体的电气设备供电,由液压升降机构控制上车架升降调整高度,替换了常用悬吊式行车,车体高度较低,不需要登高作业,检修方便,使用液压升降机构实现升降,升降、行走过程中不会产生晃动,管道更加稳定,避免了皮带、绳索带动形成升降存在的车体晃动导致管道晃动的问题,降低了安全隐患。
