The invention discloses a crane anti-unhooking device in the technical field of cranes. A gear is rotationally connected to a first supporting seat, a stop lever is connected to the gear, a rack is connected to a second supporting seat, the rack is meshed with the gear, and the first supporting seat and the second supporting seat can vertically move relatively, so that the rack drives the gear to rotate. The gravity of a to-be-lifted object and the elastic force of the reset piece are ingeniously utilized, and when the to-be-lifted object is lifted, the stop lever automatically shields the opening of the lifting hook under the transmission of the gear and the rack by utilizing the gravity of the to-be-lifted object; when the to-be-lifted object reaches a designated position, the to-be-lifted object is put down, manual operation is not needed, and the opening portion of the lifting hook is automatically opened through the elastic force of the reset piece and the transmission of the gear and the rack by the stop lever. The technical problems that in the prior art, a hook body can only be taken down by manually pulling out a limiting pin, operation is inconvenient, and working efficiency is low are solved, and operation convenience and working efficiency are improved.

    本发明公开了起重机技术领域的一种起重机防脱钩装置,通过将齿轮转动连接于第一支撑座,挡杆连接于齿轮,齿条连接于第二支撑座,齿条与齿轮相啮合,第一支撑座和第二支撑座可相对竖直移动,使齿条驱动齿轮转动。巧妙地利用待吊物重力和复位件的弹力,当吊起待吊物时,利用待吊物重力,挡杆在齿轮和齿条的传动下,自动遮蔽吊钩的口部;当待吊物到达指定位置时,放下待吊物,无需人工操作,利用复位件的弹力,挡杆在齿轮和齿条的传动下,自动打开吊钩的口部。本发明解决了现有技术依赖人工拔出限位销才能取下勾体,所存在的操作不便、工作效率低的技术问题,提高了操作便捷性和工作效率。
