Embodiment Construction
[0018] Such as figure 1 and figure 2 As shown, the walking device of the present invention includes a sliding part 1, a carrying part 2, a connecting part 3 connecting the sliding part 1 and the carrying part 2, and a traction part (not shown) for pulling the sliding part 1. The slide part 1 is clamped on both sides of the container wall 4 and can slide along these sides. The carrying part 2 is used to carry the fixed weld seam radiographic inspection machine 5 and can slide along one side of the container wall 4 .
[0019] Such as image 3 As shown, the sliding part 1 includes a sliding suspension frame 6 , a traveling wheel structure 7 and a sliding clamping part 8 . The sliding suspension frame 6 includes a support rod 9 supporting the traveling wheel structure 7 , a pulley assembly rod 10 perpendicular to the support rod 9 , and a suspension rod 11 perpendicular to the support rod 9 and the pulley assembly rod 10 . The supporting rod 9, the pulley assembly rod 10 and ...

The invention relates to the field of inspection of welding joints in large containers in installation processes of nuclear power stations, petroleum, chemical engineering and the like, in particular to a travelling device for a welding joint radiological inspecting machine, which comprises a sliding part, a bearing part, a connection part and a traction part. The sliding part abuts against the upper end and two sides of the wall of a container from the upper portion and two sides and can slide along the wall of the container. The bearing part bears and fixes the welding joint radiological inspecting machine and is provided with a sliding structure sliding along the wall of the container. One end of the connection part is connected with the sliding part, and the other end of the connection part is connected with the bearing part. The traction part leads the sliding part and the bearing part which are connected through the connection part to slide circumferentially along the wall of the container. The travelling device can reduce safety hazards of personnel and devices, improve quality and efficiency of radiological inspection, and shorten working period.
Description
technical field [0001] The invention relates to the inspection field of welds, in particular to the inspection of welds of large containers in the installation and construction process of nuclear power plants, petroleum and chemical industries, and in particular to a traveling device for a weld seam ray inspection machine. Background technique [0002] In the installation and construction process of nuclear power plants, petroleum, chemical industry, etc., it is an important process to inspect the weld seam of large containers. These large containers include round or square tanks. During the inspection, the ray flaw detection method is usually used for inspection, especially the X-ray inspection machine for flaw detection inspection. However, there are standard requirements for focal length and alignment when performing x-ray inspection of tank welds. In the prior art, the X-ray inspection machine is often adjusted to a suitable angle and focal length on the scaffold by us...
