The further technical proposal is that the connecting device comprises a connecting screw rod and a fixing nut;

threads are arranged at two ends of the connecting screw rod and can be screwed into screw holes on the telescopic rod and the bearing rod;

at least two groups of connecting screw rods and fixing nuts are connected between the telescopic rod and the bearing rod.

Through using connecting lead screw, fixation nut to connect, can be after connecting, further adjust the distance between two spinal branch vaulting poles through the mode of screwing the nut, make the atress of flange connecting pipe more stable.

The further technical scheme is that the two telescopic rods are arranged at two ends of the bearing rod.

The telescopic rods are arranged at the two ends of the bearing rod, so that the telescopic range of the supporting beam can be further increased, and the fixing device can be adapted to more use environments.

Compared with the prior art, the utility model has at least the following beneficial effects: according to the utility model, the supporting beams are arranged at the wellhead, the two supporting beams are connected by using the connecting device, the distance between the two supporting beams is regulated by using the connecting device, a gap with a fixed width is formed between the supporting beams, the width of the gap is larger than the pipe diameter of the flange connecting pipe and smaller than the diameter of the flange connecting pipe, and the flange of the flange pipe is clamped between the two supporting beams, so that the problems of excessive carrying lifting appliances and complex operation during the stress conversion of a long pipeline can be effectively solved, the labor cost is reduced, and the working efficiency is improved.
