Abstract
The utility model relates to an external irradiating gamma source quick positioning clamping device for pipeline flaw detection, which comprises a positioning support bracket, a gamma source supporting sleeve, moving support arms, a negative support plate and pressing knobs. The utility model is characterized in that two moving support arms and the two arms of the positioning support bracket are connected by pin axles and locking nuts, and the moving support arms and the two arms of the positioning support bracket have corresponding rotation if the locking nuts are loosen. The other ends of the moving support arms are connected with the negative support plate through nuts, the negative support plate is pressed on a pipe wall through the pressing knobs, and the negative is aimed at a gamma source. The utility model is fixed on a pipeline by the four ball supports of the four arms, and the diametral pitch of the device can be regulated by a spring. The utility model has the advantages of fast and accurate positioning and convenient clamp and movement.
Description
The utility model relates to the γ source clamp device that the pipeline gamma ray inspection is used, and relates in particular to the quick positioning clamping device in a kind of pipeline inspection outside exposure method γ source.
Pipeline is the critical piece of mass transport such as the gas, liquid in the industrial enterprises such as chemical industry, metallurgy, in the urban construction, if leaking, breaking and will cause the heavy losses of life, property appears in pipeline, for this reason, often adopt gamma ray inspection discovery weld defect to eliminate the hidden danger of pipeline accident.But the γ source clamp device that existing pipeline gamma-rays outside exposure method is used exists complex structure, Heavy Weight, egative film location to be forbidden, and clamps insecure, disadvantages such as operation labour intensity is big, displacement inconvenience.
The purpose of this utility model be to provide a kind of compact conformation, in light weight, accurate positioning, fast location, degree of tightness, be shifted easily that γ penetrates positioning clamping device.
The purpose of this utility model is to realize like this, the quick positioning clamping device in a kind of pipeline inspection outside exposure method γ source, include fixed support, γ source support set, the egative film support plate, compress knob, wherein γ source supporting sleeve is arranged on the center line at fixed support top, it is characterized in that fixed support is inverted V-shaped, and each connects a movable arms with bearing pin the lower end of its two arm, respectively be provided with the Ball support that has spring on the afterbody screw rod on support bracket fastened two arms and two movable arms, be provided with the fixedly screw of egative film support plate in the lower end of movable arms, the egative film support plate, it is a stepped circular arc plate, its circular arc arc and pipeline are complementary, and circular arc and pipeline enclosure leave the gap of reloading before the ladder, be provided with 2 on the egative film support plate egative film evenly is pressed on the knob that compresses on the tube wall, the fixed arm and the lever arm of V-shaped rest are affixed by bolt.
The positioning clamping device of said structure, in use, earlier fixed arm being connected bearing pin with lever arm unclamps, also the set nut with web joint and lever arm unclamps, then two Ball supports on the fixed support are contacted with pipeline outer wall, the egative film support plate screwed be placed in the pipeline bottom, be that the arm support arm of living is rotated at the center again with the bearing pin, two Ball supports on the movable arms are also contacted with the pipeline outer arm, use bolt then, set nut is located movable arms one end, with nut bearing pin is located again, clamp device can be positioned the γ source on the tested pipeline rapidly and accurately, because four Ball supports on fixed support and the movable arms all are provided with spring on its afterbody screw rod, so this clamp device can rotate and move axially also clamping and positioning easily in a certain position on pipeline under the effect of Ball support spring force.When pipe diameter changes, as long as unclamp these nuts, knob, just can change institute's clamping pipeline fast, thereby make the utility model can realize quick degree of tightness, the requirement of location fast.
The utility model has the advantages that: easy to operate, accurate positioning, rotation displacement is flexible, the efficient height, labour intensity is little, and the egative film accurate positioning is firm, and the egative film shooting quality is good.
Come further structure of the present utility model to be illustrated with embodiment and accompanying drawing below
