Embodiment Construction
[0012] The present invention will be further described below in conjunction with the drawings.
[0013] A spiral welded pipe X-ray detector arm device, such as figure 1 , figure 2 , image 3 , Figure 4 with Figure 5 Shown, it is a device for internal quality inspection of spiral welded steel pipe welds, and it is also suitable for internal quality inspection of straight welded steel pipe welds, especially for lengths of 6 to 18 meters, diameters of φ219 mm to φ2800 The X-ray detector for the detection of millimeter steel pipe welds. The device is composed of a probe arm body 1, a probe arm lifting device 2, and a probe arm translation device 3. The probe arm body 1 is installed on the probe arm lifting device 2, and the probe arm lifting device 2 is installed on the probe arm translation device 3. Above. The liftable probe arm lifting device 2 supports and lifts the probe arm body 1 and can move in a horizontal direction under the action of the probe arm translation device 3...

Abstract
The invention relates to an arm device for a spiral welded pipe X-ray detector, which is composed of an arm lifting device arranged above an arm shifting device and an arm body arranged on the arm lifting device. The invention has functions of being capable of adjusting and selecting upper irradiation and side irradiation of X-ray radiographic inspection on the inner quality of the welding line of a spiral-welded steel tube and a straight seam steel tube, and solves the problem that the existing arm device for the spiral welded pipe X-ray detector can only be applied to the upper irradiation and the side irradiation of welding lines and has single function and poor practical applicability, thereby improving the usability of the X-ray in the field of large steel tube welding line detection, improving the detection speed and reducing the detection cost. The structure of the invention is compact in design, and the original structure with huge volume is improved into a more reasonable integral structure by a method of function combination and transmission concentration, and the balance weight is added to achieve the balance of the long-arm X-ray the pipe end and a mechanism so as to enable the instrument to be stable in the operation with the characteristics of reliable operation and low cost.
Description
Technical field: [0001] The invention relates to an X-ray detection instrument component, in particular to a spiral welded pipe X-ray detector arm device for performing X-ray inspection on the internal quality of the spiral welded pipe weld. Background technique: [0002] The steel pipe must undergo strict quality inspection before leaving the factory to determine whether there are any hidden quality problems in the weld that may damage the service life of the product. The probe arm device is an important part of the mechanical transmission system of the spiral welded pipe X-ray inspection machine. The existing spiral welded pipe X-ray inspection machine's probe arm device can only illuminate the weld seam up or sideways, with single function and poor practicability; the existing probe arm The device is bulky, costly, unable to move, and difficult to operate, resulting in low production efficiency of the entire device. With the rapid development of my country's economy, especial...
