Description

Technical Field

[0001] The utility model relates to the technical field of non-destructive testing, in particular to an infrared thermal imager for non-destructive testing. Background Art

[0002] Nondestructive testing refers to the use of changes in heat, sound, light, electricity, magnetism and other reactions caused by abnormal internal structure or defects of materials to inspect the inside of mechanical materials without damaging or affecting the performance of the tested object or the internal organization of the tested object. Infrared thermal imagers are usually used in nondestructive testing.

[0003] However, when using existing infrared thermal imagers, workers usually hold the infrared thermal imagers to inspect the pipeline to be inspected. The handheld infrared thermal imagers have poor stability, and the workers' labor intensity is high and they are prone to fatigue when holding the infrared thermal imagers for a long time.

[0007] The clamping assembly includes a fixed plate, a bidirectional screw rod passes through the interior of the fixed plate, one end of the bidirectional screw rod is connected to a rocker, the outer wall of the bidirectional screw rod is connected to a nut pair, the outer wall of the nut pair is provided with a guide block, a movable plate is installed below the guide block, springs are installed inside the upper, middle and lower parts of the movable plate, a guide plate is provided at the end of the spring away from the movable plate, the inner side of the guide plate is connected to a shaft rod, and the outer wall of the shaft rod is connected to a roller.

[0008] Preferably, the vibration damping assembly comprises a mounting plate, a guide frame is provided above the four corners of the mounting plate, a vibration damper is installed inside the guide frame, a guide column is connected above the vibration damper, and a support frame is provided above the guide column.

[0009] Preferably, the bidirectional screw is rotatably connected to the fixed plate, and the guide block is fixedly connected to the nut pair.

[0010] Preferably, the guide block is slidably connected to the fixed plate, and the movable plate is fixedly connected to the guide block.

[0011] Preferably, two ends of the spring are fixedly connected to the movable plate and the guide plate respectively, and the roller is rotationally connected to the shaft rod.

[0012] Preferably, the mounting plate is fixedly connected to the fixing plate, and the two ends of the shock absorber are fixedly connected to the mounting plate and the guide column respectively.

[0013] Preferably, the guide column is slidably connected to the guide frame, the support frame is fixedly connected to the guide column, and the infrared thermal imager body is fixedly connected to the support frame.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The new infrared thermal imager can place the pipeline to be inspected between two moving plates by setting a clamping assembly. The rocker drives the bidirectional screw to rotate, and the bidirectional screw drives the nut pair to move closer to each other. The nut pair drives the guide block and the moving plate to move closer to each other, and finally the roller abuts against the pipeline. The spring plays a buffering role, making the clamping more stable. The staff only needs to push the clamping assembly to drive the infrared thermal imager body to inspect the pipeline, which greatly reduces the labor intensity. The stability during inspection is high, and the inspection efficiency is improved.

[0016] (2) The new infrared thermal imager is equipped with a vibration reduction component so that the infrared thermal imager body does not directly contact the clamping component. The vibration generated by the roller rolling on the pipe surface is transmitted to the vibration absorber, which plays a role in energy dissipation and vibration reduction, so that the infrared thermal imager body can move smoothly above the pipe, making it convenient for staff to observe the detection results.
