Abstract
Description
Technical Field
[0001] This utility model relates to the field of flaw detection device technology, and in particular to a flaw detection device for steel wire rope of building tower crane. Background Technology
[0002] Tower cranes are indispensable lifting equipment in modern construction, especially in large-scale projects such as high-rise buildings, bridges, and ports, where they undertake critical tasks such as lifting building materials and installing components. Their efficient and safe operation directly affects the project's progress and quality. However, during long-term use, due to frequent lifting of heavy objects and complex operating conditions, key components of tower cranes, such as wire ropes, are prone to wear, fatigue, and wire breakage, posing significant safety hazards. Therefore, it is necessary to use flaw detection devices to inspect the wire ropes.
[0003] However, existing flaw detection devices for steel wire ropes of tower cranes still have certain defects. For example, the position of the rollers used to move the flaw detection equipment cannot be adjusted, which means that the device can usually only detect flaws in steel wire ropes of a specific size, making it impractical. Secondly, the flaw detection is usually performed directly on the steel wire rope, but the steel wire rope is usually outdoors, so there will be a lot of impurities on the surface, and the adhesion of impurities will affect the accuracy of the flaw detection equipment.

The upper body 5 is then flipped again, and the sub-magnet plate 6 and the female magnet plate 7 are brought into contact to close the lower body 1 and the upper body 5. Then, depending on the thickness of the wire rope, the hexagonal rotating block 11 is rotated, which drives the threaded rod 10 to drive the two corresponding rollers 15 to move closer to each other through the connecting frame 13, thereby contacting the wire rope. Then, while moving, the handle 8 on this device is pulled to... This device allows for smooth movement along the wire rope, enabling flaw detection. The position adjustment of the roller 15 allows the device to be used with wire ropes of various thicknesses. During the movement of the device, the forward and reverse motors 17 are simultaneously activated, driving the drive shaft 18 to rotate the pinion 19 back and forth. In turn, the meshing action of the drive shaft 18 and the half-gear 21 drives the semi-annular brush plate 22 to rotate back and forth under the limiting action of the limiting rod 26, thereby cleaning the surface of the wire rope and improving the accuracy of the flaw detection results.
