DETAILED DESCRIPTION
[0015] In order to make the purpose, technical scheme and advantages of the utility model embodiments of the present invention clearer, the technical scheme in the utility model embodiments will be clearly and completely described below in conjunction with the drawings in the utility model embodiments. Obviously, the described embodiments are part of the utility model embodiments, not all embodiments. Generally, the components of the utility model embodiments described and shown in the drawings here can be arranged and designed in various different configurations.
[0016] like Figure 1 , 2 As shown in Figures 3 and 4, a non-destructive steel pipe detection device includes a device frame 1, on which a conveying roller 2 for conveying the steel pipe from right to left is installed, the conveying roller is connected to a conveying motor 21, above the conveying roller is a placement station for detecting the steel pipe 3, below the placement station, on the device frame is a ray receiving plate 4, the ray receiving plate is connected to a data processing device, and the situation of the inner wall of the steel pipe at the irradiated part can be understood through the ray signal processed by the data processing device, a vertical plate 5 is installed on the right side of the device frame, and a pull rope 51 is connected to the vertical plate, it also includes a trolley 6, and a ray emitting source 41 is installed on the trolley; its feature is that: a rotating roller 7 connected to a rotating motor 71 is also installed on the device frame, the rotating roller contacts the placement station, the rotating motor runs, drives the rotating roller, and can drive the steel pipe to be monitored to be turned over.
[0017] Using principle, the above arrangement of the utility model can realize that the steel pipe is turned over by the rotating roller while running from right to left, that is, the steel pipe runs in a spiral, and by adjusting the appropriate running speed of the rotating roller, the weld can always be at the place where the radiation emission source irradiates, that is, the weld 10 is always detected.
[0018] The ray emitting source, ray receiving plate and data processing device are components in the prior art, and they are technologies and components in the prior art that can detect the condition of the inner wall of the steel pipe.
[0019] The arrangement of the pull rope can ensure that the trolley is always above the radiation receiving plate, that is, the radiation emitting source can always be directed toward the radiation receiving plate.
[0020] Furthermore, the rotating motor is also connected to a control device, and the conveying motor is connected to the control device, and the control device can control the operating speeds of the rotating motor and the conveying motor.
[0021] The above configuration of the utility model can adjust the speed of the rotating motor to ensure that the position of the weld is always where the radiation source irradiates. For example, when it is observed that the position of the weld is not where the radiation source irradiates, it can be corrected by adjusting the speed of the rotating motor.
[0022] Radiographic testing is a commonly used non-destructive testing method for pipelines. It uses radiation to illuminate the inside of the pipeline and observe the penetration of the radiation to determine whether there are defects inside the pipeline. If there are defects, the radiation will produce shadows or irregular scattering at the defect, which will be detected. Radiographic testing is suitable for pipelines of various materials, such as steel pipes, cast iron pipes, plastic pipes, etc.

[0024] The trolley has wheels at the bottom, which can ensure that the trolley is always located at the bottom of the steel pipe and is in a relatively stable state.
[0025] Furthermore, the ray emitting source is also installed on the trolley through a lifting component 9. By adjusting the lifting component, the distance between the bottom of the ray emitting source and the top of the inner wall of the steel pipe can be adjusted.
