[0021] The technical solutions in the present application will be further described below with reference to the drawings and embodiments.

[0022] As shown in the drawings, Figs. 1-3 An embodiment of the present application provides a pressure pipeline inner wall inspection device suitable for different diameters, which comprises:

[0023] Base 1;

[0024] The pipeline supporting mechanism comprises two supporting plates 5 sliding on the base 1 and capable of synchronous movement, the base 1 is provided with a guide groove 3, two sliding blocks 15 are slidingly connected in the guide groove 3, the two supporting plates 5 are respectively installed on the two sliding blocks 15, a first screw rod 13 and a second screw rod 14 are rotationally connected in the guide groove 3, the first screw rod 13 and the second screw rod 14 respectively penetrate through the sliding blocks 15 on the same side and are threadedly connected with the sliding blocks 15, since the sliding blocks 15 cannot rotate in the guide groove 3 and the thread directions of the first screw rod 13 and the second screw rod 14 are opposite, when the first screw rod 13 and the second screw rod 14 rotate, the two sliding blocks 15 can move relative to or away from each other, thereby driving the two supporting plates 5 to move relative to or away from each other.

[0025] In order to facilitate the rotation of the first screw rod 13 and the second screw rod 14, the first screw rod 13 and the second screw rod 14 are connected through a round rod 12, a motor 2 is installed on the base 1, and the output end of the motor 2 is connected with the second screw rod 14, so that the motor 2 drives the round rod 12, the first screw rod 13 and the second screw rod 14 to rotate.

[0026] A conical barrel 6 is penetratingly and fixedly connected on the supporting plate 5, and a circular ring is fixed on the end of the conical barrel 6, penetrating through the supporting plate 5 and fixedly connected therewith; the two conical barrels 6 extend to the two ends of the pipeline and abut against the pipeline, capable of supporting the pipelines with different diameters, so as to clamp and support the pipeline from the two ends of the pipeline.

[0027] The inspection mechanism is coaxially arranged with the conical barrel 6, when the conical barrel 6 fixes the pipeline, the conical barrel 6 is coaxially arranged with the pipeline at this time, so that the inspection mechanism is also coaxial with the pipeline at this time, so as to facilitate subsequent detection, and even if different pipelines are replaced, the inspection mechanism does not need to be adjusted.

[0028] The inspection mechanism is installed on the base 1 and can move to the inside of the pipeline through the conical barrel 6, and the inspection mechanism comprises a mounting plate 11 installed on the base 1, a second electric push rod 9 installed on the mounting plate 11, and a detection piece 10 installed on the output end of the second electric push rod 9.

[0030] The above detection is to clamp and position the pipe.

[0031] Before clamping and positioning the pipe, the pipe needs to be pre-supported so as to extend the conical cylinder 6 into the pipe, and for this purpose, an auxiliary supporting assembly is further included; the auxiliary supporting assembly includes a supporting block 4 fixed in the guide groove 3, a round rod 12 penetrating through the supporting block 4 and being rotationally connected with the supporting block 4, a first electric push rod 7 being installed on the supporting block 4, and an arc-shaped plate 8 being fixed at the output end of the first electric push rod 7; the pipe is first placed on the arc-shaped plate 8, and then the first electric push rod 7 drives the arc-shaped plate 8 to move upwards, thereby driving the pipe to move upwards, so that the position of the pipe can be guaranteed to extend the conical cylinder 6 into the pipe, and thus the pre-supporting of the pipe is realized;

[0032] In order to guarantee the stable upward and downward movement of the arc-shaped plate 8, an extension rod connected with the arc-shaped plate 8 can be installed on the base 1 to guide the arc-shaped plate 8.
