Description

Technical Field

[0001] This application relates to the field of non-destructive testing of welds, and in particular to a non-destructive testing device for welds in steel structures. Background Technology

[0002] Steel structure welds are joints formed by melting welding rods or wires with metal using a welding heat source and then cooling the melted metal. Steel structure welds are often inspected using non-destructive testing (NDT) machines. Non-destructive ultrasonic testing of welds is a method that uses ultrasonic technology to perform non-destructive testing on welds. It is mainly used to detect the presence of defects such as cracks, porosity, sand holes, and inclusions within the weld, and to determine their location, size, and nature. Ultrasonic testing involves a probe emitting sound waves and receiving reflected waves, analyzing waveform changes to identify internal material defects. When ultrasonic waves encounter defects in the weld, some sound waves are reflected or attenuated. The receiver can then accurately locate the defect and determine its severity. In conventional weld NDT machines, one end of the machine is connected to a testing probe via a connecting cable. After the probe is brought into contact with the area to be inspected, it emits sound waves and receives reflected waves, analyzing waveform changes to identify internal material defects and complete the weld inspection.

[0003] Regarding the aforementioned technologies, the inventors believe that when inspecting conventional steel structure welds, the inspection probe is often manually held by hand to check the area to be inspected. This results in workers maintaining a squatting posture for extended periods during long-distance inspections, which can easily cause discomfort in the lower back and legs, thus making the inspection of steel structure welds inconvenient.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the inconvenience of operating conventional weld non-destructive testing equipment, this application provides a non-destructive testing device for steel structure welds.

[0006] The non-destructive testing device for steel structure welds provided in this application adopts the following technical solution:

[0007] A non-destructive testing device for steel structure welds includes a weld inspection instrument and a support rod. A connecting line is fixedly installed at one end of the weld inspection instrument, and a detection probe is fixedly connected to the end of the connecting line away from the weld inspection instrument. A sliding frame is slidably mounted on the surface of the support rod, and an adjustment frame is fixedly connected to the bottom end of the sliding frame. The bottom end of the adjustment frame is rotatably mounted to the surface of the detection probe. Two pulleys are rotatably connected to the bottom end of the support rod. The dimensions of the support rod surface are adapted to the dimensions of the inner wall of the sliding frame. The two pulleys are symmetrically distributed about the support rod as an axis. The center of the adjustment frame and the center of the support rod are on the same straight line.

[0008] Preferably, a push spring is fixedly connected to the top of the sliding frame, the top of the push spring is fixedly installed on the surface of the support rod, and the center of the push spring and the center of the support rod are on the same straight line.

[0009] Preferably, a pull rope is fixedly installed on the top of the sliding frame, and a control handle is fixedly connected to the top of the pull rope. The inner wall of the control handle is slidably installed on the surface of the support rod, and the dimensions of the inner wall of the control handle are compatible with the dimensions of the surface of the support rod.

[0010] Preferably, the inner wall of the adjusting frame has two connecting grooves, which are symmetrically distributed about the adjusting frame, and a slider is slidably connected to the inner wall of the connecting groove. The surface of the slider is fixedly installed to the surface of the support rod.

[0011] Preferably, a fixing frame is fixedly connected to the top of the support rod, and an mounting frame is slidably installed on the surface of the fixing frame. One end of both the fixing frame and the mounting frame is engaged with the surface of the weld inspection instrument.

[0012] Preferably, the mounting bracket has a threaded connection to a fixing bolt, one end of which is engaged with the surface of the mounting bracket.

[0013] Preferably, a fixing strap is fixedly installed on the surface of the support rod, the inner wall of the fixing strap is snapped into the surface of the connecting line, and the surface of the fixing strap is fixedly connected with Velcro.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. By mounting a support rod on the surface of the weld inspection instrument, with a pulley rotatably connected to the bottom of the support rod, and an adjustment frame mounted on the surface of the support rod via a sliding frame, the operator can move the support rod in conjunction with the pulley to the weld position. The adjustment frame controls the contact position between the inspection probe and the weld. A push spring is mounted on the top of the sliding frame to keep the inspection probe in contact with the weld. A pull rope is mounted on the top of the sliding frame, and a control handle is mounted on the top of the pull rope to move the sliding frame upwards, thereby controlling the distance between the inspection probe and the weld. A slider is mounted on the surface of the support rod, and the surface of the slider slides in a connecting groove within the adjustment frame to limit the movement of the adjustment frame. Compared to existing technologies, this significantly improves the convenience of weld inspection.

[0016] 2. A mounting bracket can also be installed on the top of the support rod. The surface of the mounting bracket is slidably connected to a mounting frame, which allows the weld inspection instrument to be connected to the surface of the support rod.

In use, one end of the weld inspection instrument 1 is connected to a detection probe 3 via a connecting line 2. After the detection probe 3 contacts the position to be inspected, the detection probe 3 emits sound waves and receives reflected waves. The changes in the waveform are analyzed to identify internal defects in the material, thus completing the inspection of the weld. A support rod 4 is installed on the surface of the weld inspection instrument 1. A pulley 8 is rotatably connected to the bottom end of the support rod 4, and a sliding frame 5 is slidably connected to the surface of the support rod 4.

[0024] Reference Figure 2 A push spring 7 is installed on the top of the sliding frame 5. The top of the push spring 7 is fixedly connected to the surface of the support rod 4. The push spring 7 pushes the sliding frame 5 to keep the detection probe 3 in the adjustment frame 6 in contact with the weld, thereby ensuring the detection effect of the detection probe 3. A pull rope 9 is installed on the top of the sliding frame 5. A control handle 10 is installed on the top of the pull rope 9. The inner wall of the control handle 10 is slidably connected to the surface of the support rod 4.
