Abstract

This utility model relates to the field of drilling rig anchor bolt technology, and discloses an anchor bolt for drilling rigs, including an anchor bolt body with two sets of anchor bolt bodies. A connecting block is installed at one end of the anchor bolt body, and a threaded cylinder is installed at the other end. The connecting block includes a limiting cylinder and a threaded post, with the threaded post fixed inside the limiting cylinder. This utility model, by setting a locking block, a locking groove, and a screw, allows for easy removal of the anchor bolt. If frequent disassembly and assembly damages the connecting thread mechanism, rendering it unusable, the screw can be rotated until it separates from the threaded groove. The screw can then be completely pulled out, at which point the locking block and locking groove are separated. Force can then be applied to pull out the damaged threaded cylinder or limiting cylinder, and new components can be selectively replaced. The new threaded cylinder can then be screwed onto the threaded post, allowing the anchor bolt to continue to be used. Compared to the current practice of discarding anchor bolts once damaged, this reduces the cost of anchor bolt usage.
