Self-recovery grab bucket with toughness, control method and micro pile grab bucket hole forming equipment
The invention belongs to the field of pile foundation construction equipment, and particularly discloses a self-recovery grab bucket with toughness, a control method and micro pile grab bucket hole forming equipment. The grab bucket comprises bucket petals with grab bucket teeth. The grab bucket teeth are arranged at the lower ends of the bucket petals through tooth changing mechanisms; the tooth changing mechanism comprises a tooth box, an inner cavity of the tooth box is a tooth containing cavity, and a tooth locking assembly and a tooth changing driving component are arranged in the tooth containing cavity. According to the grab bucket, under the condition that grab bucket teeth are broken or excessively abraded, the grab bucket teeth in transmission fit with the grab bucket teeth can be driven by the tooth changing driving component to move towards the tooth passing opening, and the grab bucket tooth located at the first position is extruded out of the tooth containing cavity; the grab bucket teeth in the second syn-position move to the position where the first limiting structures of the grab bucket teeth are matched with the second limiting structures of the lock tooth assemblies, the function of automatically replacing the grab bucket teeth is achieved, it is ensured that the grab bucket can rapidly recover to the normal state to continue drilling, the grab bucket teeth do not need to be disassembled, assembled and replaced manually, and the working efficiency is improved. Therefore, the labor intensity of workers is not increased, and the construction efficiency is ensured.
本发明属于桩基施工设备领域，具体公开了一种具有韧性的自恢复抓斗和操控方法及微型桩抓斗成孔设备。该抓斗包括带抓斗齿的斗瓣；抓斗齿通过换齿机构设置在斗瓣的下端；换齿机构包括齿匣，齿匣的内腔为齿容纳腔，齿容纳腔内设置有锁齿组件和换齿驱动部件。该抓斗在抓斗齿断裂或磨损过度的情况下，可通过换齿驱动部件驱使与之传动配合的抓斗齿朝向过齿口运动并将处于首位的抓斗齿挤出齿容纳腔，且使处于第二顺位的抓斗齿运动至其第一限位结构与锁齿组件的第二限位结构配合在一起的位置，实现自动更换抓斗齿的功能，确保抓斗能够快速恢复到正常状态继续钻削，无需依靠人力对抓斗齿进行拆装更换，因此不会增加人工劳动强度，并保证了施工效率。
