After the connection of the duct body is completed, the elevator drives the two lifting longitudinal beams to lift, and the duct body connected end to end is lifted together with the supporting crossbeam. The duct body is lifted to the connecting rod bracket, and the supporting crossbeam is guided by the guide rope so that the end of the connecting bracket passes through the connecting through hole.

[0019] The present invention is further configured as follows: a connecting hole is provided at the bottom of the connecting rod, a connecting hook is fixedly connected to the end of the guide rope, and the connecting hook passes through the connecting hole and is connected to the connecting rod.
