Embodiment Construction

[0018] See attached figure 1 , which describes a preferred embodiment of the welding seam radiography automatic patch robot according to the present invention. The robot includes a frame, a frame traveling mechanism carrying the frame to move, a real-time detection system located on the upper part of the frame, and a lead box for storing films.

[0019] The rack walking mechanism includes a six-wheel walking trolley, which includes four wheels at both ends of the trolley and two universal wheels at the bottom of the trolley; the four wheels are symmetrically arranged at both ends of the trolley, and any wheel at the front and rear ends is the active wheel. Each driving wheel has a driving wheel shaft and a wheel drive motor respectively. The wheel driving motor is connected to the driving wheel shaft through a coupling. There are two rolling bearings between the driving wheel shaft and the driving wheel. The driving motor drives the driving wheel shaft to rotate, thereby drivi...

Abstract

The invention discloses an automatic paster robot for weld radiographic inspection, which comprises a rack, a rack travelling mechanism carrying the rack to move, a real-time detection system located at the upper part of the rack, and a lead box used for storing a film. The automatic paster robot has the advantages that the labor intensity of paster inspection is reduced; the working efficiency is improved effectively; the operation is remote; personal injuries of radiation to operating personnel are reduced; and the automatic paster robot is low in manufacturing cost, easy to process and manufacture, simple and convenient to control, and high in accuracy, is applied to practical production, and can improve economic benefits of the radiographic inspection greatly.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to an automatic patch robot for welding seam radiographic flaw detection. Background technique [0002] Radiographic flaw detection is one of the commonly used non-destructive testing methods in the manufacturing process of pressure vessels, shipbuilding, boilers and other equipment. It has the following characteristics: ①The detection results can be directly recorded on the film; The detection rate of defects is the highest and the detection rate of area defects is affected by many factors; ④It is suitable for inspecting thinner workpieces but not for thicker workpieces; ⑤It is suitable for detecting butt welds, and the detection effect of fillet welds is poor. It is not suitable for detecting plates, slabs and forgings. [0003] In radiographic testing, especially in welding seam testing in the manufacturing process of pressure vessels, manual testing is mainly used, which has di...
