When the large-caliber special pipeline needs to be transported, the large-caliber special pipeline is arranged between the two groups of transport wheels (72), and the large-caliber special pipeline is driven to be transported in the transport groove (101) by manually pushing the large-caliber special pipeline, wherein the size of the opposite ends of the two groups of transport wheels (72) is smaller than that of the opposite ends of the two groups of transport wheels (72), so that the large-caliber special pipeline is always arranged between the two groups of transport wheels (72) in the transportation process, and the stability of the large-caliber special pipeline during transportation is further improved;
step two, multi-directional clamping of large-caliber special pipeline
The large-caliber special pipeline is transported in a transportation groove (101), passes through a multidirectional clamping assembly (3) until a processing port of the large-caliber special pipeline corresponds to a plurality of groups of power heads (5), then, is controlled and started to extend by a telescopic cylinder (35), drives a driving rack (341) to move up and down, further drives a driving ring (32) to rotate at one side of an assembly ring frame (31) by meshing the driving rack (341) with a driving gear ring (34), further drives a ring protrusion (321) to rotate in a through groove (312), drives a flat thread protrusion (322) to rotate by taking the center of the ring protrusion (321) as the center of a circle by rotating the ring protrusion (321) in the through groove (312), further synchronously drives a plurality of groups of clamping rods (33) to stably extend and retract in the corresponding T-shaped telescopic grooves (311) until a rubber gasket (332) contacts with the outer wall of the large-caliber special pipeline, therefore, the large-caliber special pipelines positioned among the groups of clamping rods (33) are clamped and fixed in a multi-way manner, the stability of the large-caliber special pipelines in processing is improved, the processing efficiency of the large-caliber special pipelines is improved, the large-caliber special pipelines with different sizes can be flexibly clamped, and the flexibility of the whole device is improved;
step three, groove processing of large-diameter special pipeline
Through controlling and starting drive motor (45), drive gear (451) and rotate, through the meshing of indirect gear (452), can drive driven ring gear (43) and rotate, and then drive annular inside casing (42) and rotate at the inner wall of annular frame (41), thereby drive multiunit unit head (5) and use the centre of a circle of annular inside casing (42) as the center and rotate, realize carrying out multiunit unit head (5) rotary type groove machining to the port of heavy-calibre special type pipeline, the port groove machining efficiency of heavy-calibre special type pipeline has been promoted, wherein, through synchronous control multiunit electric telescopic handle (44), drive multiunit head (5) and stretch out and draw back in step, the groove machining of the port of convenient heavy-calibre special type pipeline that carries out the gradual shrink, the port groove machining efficiency of heavy-calibre special type pipeline has further been promoted.
