X-ray steel pipe seam detection supporting arm device

Abstract

The invention relates to an X-ray steel pipe seam detection supporting arm device, wherein bottom parts of two main vertical posts and two auxiliary vertical posts are fixed on a base, upper end parts of the vertical posts are connected through a front stiffening beam and a back stiffening beam, a main screw and an auxiliary screw are respectively arranged between two main vertical posts and two auxiliary vertical posts, the upper ends of the main vertical posts, the main screw, the auxiliary vertical posts and the auxiliary screw are respectively connected with crossbeams, the main screw and the auxiliary screw are respectively connected with a key shaft of a speed reduction motor, which is arranged at the top ends of the screws, a lifting device is connected with the main screw and the auxiliary screw, a supporting arm is connected with the lifting device, and an X-ray tube is arranged on the front end of the supporting arm. When the X-ray steel pipe seam detection supporting device works, the double screws can drive the supporting arm to rise up and down, one of the screws is used for regulating levelness, and then the X-ray tube fixed on the front end of the supporting arm extends to the inside of a welded tube to conduct real-time imaging or shooting for seams of the welded tube or other projects to be detected, therefore, the operations are simple and convenient, the positioning is accurate, and the one-step success rate is high in the detection of long tubes.

Description

technical field [0001] The invention relates to an X-ray detection device, in particular to a probe arm device required for X-ray detection of steel pipe weld seams. Background technique [0002] Welded steel pipes are widely used in modern industries, especially in petrochemical, high-voltage switchgear and other fields. The length, diameter and other specifications span are also very large. Some welded pipes have a long detection length, which requires a fixed X-ray tube detection arm device , To reduce bending and ensure the corresponding levelness, especially for small-diameter welded pipes, only in this way can the probe arm be smoothly inserted into the welded pipe for inspection. The existing probe arm device is to install a ray tube at the front end, add a counterweight to the rear end for balance control, and a rotating shaft in the middle can be adjusted to a certain extent, but the adjustment and positioning of this adjustment method are not easy to control and th...

Problems solved by technology

The existing detection arm device is to install a ray tube at the front end, add a counterweight to the rear end for balance control, and a rotating shaft in the middle can be adjusted to a certain extent, but this adjustment method is not easy to control the adjustment and positioning, and the positioning is not accurate

At the same time, because the existing detection arm device uses a single screw to control the lifting, the screw is lifted from the bottom to the top, so that the screw is in a state of compression, the stability is not very good, and it is supported and positioned by two columns. Also affects the stability of the device
