When the user needs to weld the pipelines with different diameters, the user can synchronously control the hydraulic cylinders 14 on the surface of the connecting plate 11, the hydraulic cylinders 14 drive the extrusion blocks 15 to press on the surface of the pipeline, and then the connecting plate 11 is fixed on the surface of the pipeline, and when the pipelines with different sizes are faced, the adaptation of the pipelines with different sizes can be completed only by adjusting the telescopic distance of the hydraulic cylinders 14.
When welding gun 3 welds the seam crossing of pipeline, in order to guarantee that two wait to weld the pipeline contact surface and can laminate completely, the user can insert sleeve 16 on the surface of slide bar 2 to insert bolt 19 in connecting hole 18 and jack 17, in order to accomplish the fixed to sleeve 16, sleeve 16 surface hydraulic stem 20 starts afterwards, then the flexible end of hydraulic stem 20 just can press the accepting plate 21 on connecting plate 11 surface, make accepting plate 21 drive the link with it fixed pipeline be close to each other, and sticis once, thereby guarantee that the abundant welding of two pipelines is in the same place, avoid appearing the condition of gap in the welded part.
When the embodiment of the invention is arranged outside a welding area, a user can screw a screw rod into the threaded hole 22 on the surface of the bearing plate 21, then the hydraulic cylinder 14 on the surface of the connecting plate 11 at one end is started to drive the extrusion block 15 to press the surface of a pipeline to finish fixing the connecting plate 11, the hydraulic cylinder 14 at the other end pulls the extrusion block 15 away from the surface of the pipeline so that the connecting plate 11 can move along the surface of the pipeline, then the hydraulic rod 20 is started to push the connecting plate 11 to the arc plate 1, then the hydraulic cylinder 14 at the side is started to fix the connecting plate 11, the hydraulic cylinder 14 at the other side drives the extrusion block 15 to be away from the surface of the pipeline to release the locking between the connecting plate 11 and the pipeline, and then the hydraulic rod 20 which previously pushes the connecting plate 11 to one side of the arc plate 1 is contracted to drive the sleeve 16, the slide rod 2, the arc plate 1 and the connecting plate 11 at the other side to move along the pipeline, so that the embodiment of the invention can move along the pipeline, thereby the embodiment of the invention can move to the drive the arc plate to be welded, and the application range of the embodiment of the invention is further expanded.
When the hydraulic cylinder 14 drives the extrusion block 15 to be far away from the surface of the pipeline, the spring 25 in the extrusion block 15 can push the connecting seat 26 out of the mounting groove 24, so that the roller 27 can extend out of the mounting groove 24 and provide support, and the welding gun 3 at the arc plate 1 is prevented from being directly crashed to the surface of the pipeline, so that the welding gun 3 is prevented from being damaged.
When the movable seat 7 rotates along the arc-shaped plate 1, the conductive rod 31 slides along the sliding groove 29 on the surface of the insulating seat 28, and the surface of the conductive rod 31 always contacts with the conductive plate 30, so that the servo motor 8 can be normally electrified and used, and meanwhile, the condition that the connection line between the servo motor 8 and an external power supply is wound on the surface of the sliding rod 2 in the process of rotating the servo motor 8 around the arc-shaped plate 1 is avoided.
When the movable seat 7 rotates along the arc-shaped plate 1, the movable seat 7 can squeeze out the water discharging sheets at the two sides of the insulating seat 28, so that the movable seat 7 can normally move on the surface of the arc-shaped plate 1, and when the movable seat 7 does not squeeze the water discharging sheets any more, the two water discharging sheets can be elastically attached by themselves, so that the sliding grooves 29 on the surface of the insulating seat 28 are shielded, and the situation that liquid enters the knife conductive groove to cause electric leakage is avoided.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
