The number of annular pressing plates 8 are all located inside the connecting sleeve 7. A rubber sealing ring 9 is arranged between two adjacent annular pressing plates 8. The inner surface of the rubber sealing ring 9 abuts against the surface of the original operating pipeline 1. The number of annular pressing plates 8 abut between the clamping tile 6 and the connecting sleeve 7. That is, when the connecting sleeve 7 moves, a pressing force can be applied to the annular pressing plates 8 and the rubber sealing ring 9. A number of locking bolts 10 are fixedly arranged at one end of the connecting sleeve 7 close to the locking sleeve 4 in a circular array. One end of the number of locking bolts 10 far from the connecting sleeve 7 penetrates through the locking sleeve 4. Locking nuts 11 are threadedly connected to the surfaces of the locking bolts 10. The locking nuts 11 all abut against one end of the locking sleeve 4 far from the connecting sleeve 7. Specifically, the operator can control the locking bolts 10 to drive the connecting sleeve 7 to move by rotating the locking nuts 11, so as to apply a pressing force to the annular pressing plates 8 and the rubber sealing ring 9, causing the rubber sealing ring 9 to be deformed by extrusion, so as to be extrusion-sealed with the surface of the original operating pipeline 1 to prevent leakage;

[0022] In summary, the device can quickly and weld-free connect a new pipeline to the end of the original operating pipeline, so as to quickly resume oil and gas transportation operation. And the overall structure is simple, convenient for disassembly and assembly, and easy to use.

[0023] The use process of the utility model is as follows: the operator first sets the locking sleeve 4 on the original running pipeline 1, then clamps the slip 6 on the original running pipeline 1, and clamps the slip 6 through the clamping ring 5 to fix the locking sleeve 4, then sets a plurality of annular extrusion plates 8 and rubber sealing rings 9 on the original running pipeline 1, and sets the connecting sleeve 7 on the original running pipeline 1. At this time, the plurality of annular extrusion plates 8 and rubber sealing rings 9 are abutted between the slip 6 and the connecting sleeve 7, and the locking bolt 10 passes through the locking sleeve 4. The operator tightens the locking nut 1 1 is threadedly connected to the locking bolt 10, and the locking nut 11 is continuously rotated to control the locking bolt 10 to drive the connecting sleeve 7 to move, thereby applying an extrusion force to the annular extrusion plate 8 and the rubber sealing ring 9, so that the rubber sealing ring 9 is squeezed and deformed by the force, thereby squeezing and sealing with the surface of the original running pipeline 1 to prevent leakage. Then the operator aligns the second connecting flange 13 at the end of the newly connected pipeline 2 with the first connecting flange 12 at the end of the connecting sleeve 7, and fixes the connection with the fixing bolt 3.
