Technical Field

[0001] The utility model relates to the technical field of quality inspection, in particular to a quality inspection device for a welded track. Background Art

[0002] In the process of railway construction and maintenance, welding, as a key technology for connecting tracks, its quality is crucial for ensuring the integrity and stability of the tracks. During the welding process, defects such as uneven welds, cracks, and slag inclusions may occur. These defects will seriously affect the service life of the tracks and the safety of train operation. Therefore, the quality inspection of welded tracks has become an essential and important link in railway construction and maintenance.

[0003] Traditional detection methods mostly rely on manual operation, that is, the detection personnel need to hold the detection equipment and squat beside the tracks for one-by-one inspection. This method is not only inefficient, consuming a large amount of manpower and time, but also the long-term repetitive labor is likely to cause fatigue of the detection personnel, thereby affecting the accuracy and reliability of the detection results. Therefore, a quality inspection device for a welded track is proposed. Content of the Utility Model

A clutch mechanism for starting and stopping the peristaltic mechanism is arranged at one end of the wheel shaft one away from the wheel one. A wheel shaft two is fixedly connected to the center of the side of the wheel two close to the installation support plate. The wheel shaft two is rotatably connected to one side of the installation support plate. An operation panel is fixedly connected to the top of the two installation support plates close to each other. Two welding quality detectors are arranged on the top of the operation panel. Installation plates are fixedly connected to both sides of the chassis. The installation plates are located between the wheel one and the wheel two. A detection probe for detection is fixedly connected to the bottom of the installation plate.

[0007] In a possible design, the peristaltic mechanism includes a housing, the bottom of the housing is fixedly connected to the top of the chassis, an arc-shaped receiving groove is formed on one side of the housing, a fixing plate is fixedly connected between one side of the top and one side of the bottom of the receiving groove, a hose is arranged on the circumferential inner wall of the receiving groove and penetrates through the fixing plate, the same rotating shaft is rotatably connected to the inner walls on both sides of the receiving groove, one end of the rotating shaft penetrates through one side of the housing, a second connecting member is fixedly connected to the circumferential outer wall of the rotating shaft, grooves are formed at both ends of the second connecting member, and pressing wheels are rotatably connected to the grooves through pins.
