The top-extension guide rail device 3 comprises a guide rail frame 31, a guide rail plate 32, a guide groove 33, a fixed seat 34, a threaded guide rod 35, a threaded guide block 36, a support rod 37, a clamping support block 38 and a third driving motor 39, wherein the guide rail frame 31 is a hollow groove, the left end of the guide rail frame 31 is provided with an inclination angle, the right end of the guide rail frame 31 is an arc-shaped surface, the upper end surface of the guide rail frame 31 is provided with the guide rail plate 32, the two sides of the guide rail plate 32 are provided with the guide groove 33, the right end of the guide rail plate 32 is an arc-shaped surface, the upper end surface and the lower end surface of the guide rail plate 32, which are close to the arc shape, are provided with mounting holes, the mounting holes are matched with the mounting columns 22 for mounting, the guide rail plate 32 is fixed on the mounting columns 22 through nuts, the third driving motor 39 is mounted at the middle position of the lower end surface on the right side in the, the threaded guide rod 35 is symmetrically provided with threaded guide blocks 36, one end of a stay bar 37 is respectively hinged on the two threaded guide blocks 36, the other end of the stay bar 37 is hinged on a clamping support block 38, and the upper end surface of the clamping support block 38 is provided with protrusions.

During specific work, the right end of the guide rail plate 32 is connected to the mounting column 22 through a mounting hole, the third driving motor 39 works, an output shaft of the third driving motor 39 rotates to drive the threaded guide rod 35 to rotate, the threaded guide blocks 36 on the threaded guide rod 35 move oppositely through threads, the support rod 37 is supported, the clamping support block 38 on the support rod 37 moves upwards, the clamping support block 38 is connected with the clamping groove 46 at the bottom of the trolley frame 41 when the support rod moves to a certain height, the third driving motor 39 continues to work, the left end of the transport trolley 4 is lifted, finally, the pipeline reaches a horizontal position, the gravity of the pipeline does not compress the spring plate 49 because the pipeline is horizontally placed, and the pipeline interface is matched with the main pipeline interface through the expansion spring 4910.

The middle position of the upper end face of the bearing fixing block 2872 is an arc end face.

When in work, the rotary lifting device 2 is firstly manually or mechanically placed below a multi-way or a valve to be connected, when the fixing clamp 1 on the rotary lifting device 2 is fixed on the original pipeline, the position of the rotary lifting device 2 is fixed, the rotary lifting device 2 works to ensure that the positions of the lifting mechanism 28 and the top-extending guide rail device 3 correspond, then manually or mechanically placing the pipeline into the limiting groove 42, then pushing the transport trolley 4 onto the top-extending guide rail device 3 through the wheels 45 and the guide groove 33, locking and fixing the right end of the transport trolley 4 by the supporting member 287, enabling the supporting member 287 to drive the right end of the transport trolley 4 to be lifted by the operation of the lifting mechanism 28, lifting to a proper position to stop, enabling the top-extending guide rail device 3 to operate, enabling the left end of the transport trolley 4 to be lifted, and finally placing the pipeline in a horizontal state, and the pipeline interface is matched with the main pipeline interface, and the spring plate 49 on the transport trolley 4 ensures that the pipeline interface is matched more tightly.
