The degree of penetration inside the No. 3 hollow column 6 and No. 4 hollow column 7 makes the two No. 2 arc-shaped columns 87 welded on the two No. 2 connecting columns 83 move synchronously to both sides, thereby increasing The lateral distance of the present invention; when the processing pipeline is shorter, it is necessary to laterally adjust the branch chain 8 to start moving to the inner center at the same time, and the working steering of the two drive motors 86 is adjusted to the opposite direction compared to the movement on both sides, and then according to the above-mentioned The horizontal distance of the present invention can be shortened by step movement; after the distance of the present invention is adjusted, the present invention starts to grab the pipeline, and the existing crane or crane controls two grasping branch chains of the present invention to grab the pipeline, thereby realizing the pipe-like The rapid handling function of objects has the advantages of simple operation, fast handling speed, high work efficiency and wide application range, which solves the defects of the existing special grab for pipelines, such as only one pipeline can be transported at a time, and the length of the pipeline to be grasped. And cause the difficult problems such as slow handling speed, low working efficiency and small scope of application, achieved the purpose.
