[0034] When using this device, first place the trolley inside the pressure steel pipe, and the pulley 11 on the bottom plate 1 drives the entire trolley to slide to the construction area. The operators can weld the inner wall of the pressure steel pipe on the top platform 3, the left platform 4 and the right platform 5. When there is a certain inclination angle on the inner wall of the inclined straight section of the steel pipe, the adjustment structure 6 is started to adjust and drive the movable plate 41 to rotate. When the movable plate 41 rotates to be parallel to the bottom of the inclined straight section, the adjustment is completed, which facilitates the welding work and improves the welding efficiency.

[0035] like Figure 2 , Figure 3 and Figure 4As shown, as a preferred embodiment, grooves 42 are provided at the front and rear ends of the left platform 4, and the adjustment structure 6 includes a first turntable 61, a first telescopic rod 62, a second turntable 63 and a second telescopic rod 64; the first turntable 61 is arranged in the groove 42 at the front end of the left platform 4, one end of the first telescopic rod 62 is connected to the first turntable 61, and the other end is hinged to the front end of the movable plate 41; the second turntable 63 is arranged in the groove 42 at the rear end of the left platform 4, one end of the second telescopic rod 64 is connected to the second turntable 63, and the other end is hinged to the rear end of the movable plate 41.
