Description

Technical Field

[0001] The utility model belongs to the field of crane detection, in particular to a safety detection device for crane tracks. Background Art

[0002] The straightness detection of the starter track is critical to ensure the safe and stable operation of the equipment. Excessive straightness deviation may lead to unstable operation of the starter, increase wear, and may even cause mechanical failure or accident. Through accurate straightness detection, these problems can be effectively prevented, ensuring the normal operation of mechanical equipment, extending service life, and improving safety performance. This detection is usually completed using professional measurement tools and techniques to ensure the accuracy and reliability of the data. The clamping seat of the detection device cooperates with the track. When the width of the clamping seat is fixed, it can only be applied to a specific size of guide rail, which limits the flexibility and application range of the equipment; because the clamping seat of the detection device in the related art cannot adjust the clamping width, if different specifications of guide rails are detected, multiple sets of equipment or replacement of the clamping seat are required, which increases the cost and complexity of operation. There is a problem of poor stability in the sliding cooperation between the clamping seat and the track. This is mainly because during the sliding process of the clamping seat, the hard contact may cause friction or impact between the guide rail and the clamping seat, which may not only damage the surface of the guide rail, but also affect the clamping stability. Especially when adjusting the position of the clamping seat, the lack of appropriate buffering measures will make the guide rail easy to slide or vibrate in the clamping seat, which will directly affect the detection accuracy.
