Gantry-type X-ray nondestructive detection device

Abstract

The invention discloses a gantry-type X-ray nondestructive detection device which is composed of a gantry framework, a sliding beam mechanism, a sliding beam transmission mechanism, a C-shaped arm mechanism and a C-shaped arm swinging mechanism. The sliding beam mechanism and the sliding beam transmission mechanism are installed in the gantry framework, and the C-shaped arm mechanism and the C-shaped arm swinging mechanism are installed in the sliding beam mechanism. The detection device composed of all the mechanisms is matched with a workpiece transportation vehicle with a rotary tool to place a detection workpiece on a detection position, and the detection workpiece on the workpiece transportation vehicle can relatively move and rotate front and back relative to detection equipment on the detection device. The detection equipment on the detection device completes the functions of vertically moving, moving left and right and swinging relative to the detection workpiece, and therefore focusing and data collecting can be omni-directionally performed on different detection points of the workpiece, so that imaging is clear and X-ray nondestructive detection on large castings is completed. The gantry-type X-ray nondestructive detection device is simple in structure, reliable in operation, steady in transmission, high in precision and capable of preventing a balancing weight from sliding to generate noise and meeting the customer requirements.

Description

technical field [0001] The invention relates to an X-ray non-destructive testing device, in particular to a gantry type X-ray non-destructive testing device for testing large castings. Background technique [0002] At present, the inspection equipment X-ray tube and the receiver in the X-ray non-destructive inspection device for large castings need to move up and down, left and right, and swing to cooperate with the functions of the forward and backward movement and rotation of the transport vehicle to collect the real-time data of the inspected workpiece and generate Dynamic images are used to judge the detection results. The up and down movement of the detection equipment on the detection device is mostly driven by ordinary motors in the form of chains or synchronous belts. The unsteady up and down movement of this transmission method has low precision, resulting in inaccurate image acquisition and poor imaging quality. The sliding mechanism that moves up and down needs to...

[0002] At present, the inspection equipment X-ray tube and the receiver in the X-ray non-destructive inspection device for large castings need to move up and down, left and right, and swing to cooperate with the functions of the forward and backward movement and rotation of the transport vehicle to collect the real-time data of the inspected workpiece and generate Dynamic images are used to judge the test results. The up and down movement of the detection equipment on the detection device is mostly driven by ordinary motors in the form of chains or synchronous belts. The unsteady up and down movement of this transmission mode has low precision, resulting in inaccurate image acquisition and poor imaging quality.

The sliding mechanism that moves up and down needs to add a counterweight to improve the stability of sliding, and the counterweight adopts a built-in type, and the counterweight is suspended in the inner cavity of the special-shaped tube in the column through the traction of the wire rope. Because the length of the column is limited, adding the counterweight in this way will be restricted, and at the same time, the weight slides and collides in the inner cavity of the special-shaped tube to generate noise
