The invention relates to the technical field of crane safety, and discloses a crane operation automatic collision avoidance mechanism for machining. The mechanism includes a crane frame, a solenoid and a sliding wheel, a fixing rotating shaft is fixedly connected with the left end of the sliding wheel, a limit groove is formed in the fixing rotating shaft, a shaft sleeve is arranged on the outsideof the fixing rotating shaft, the solenoid is arranged in the shaft sleeve, an iron block is arranged below the solenoid, and a limit part is fixedly connected below the iron block. An outer coil ofthe solenoid is powered off, the power-off solenoid has no magnetic attraction to the iron block, so that the iron block follows the limit part to move under the action of a reset spring, elastic force of the reset spring can make the limit part enter the limit groove, so that the fixing rotating shaft is connected with the shaft sleeve, the sliding wheel can not slide, the inertia force of a crane main body under the action of the frictional force of the sliding wheel and the ground sliding groove can be offset, and the crane main body stops to be prevented from collision, so that the effectof stopping a crane forcibly can be achieved.
本发明涉及行车安全技术领域,且公开了一种用于机械加工的行车运行自动避碰机构,包括行车架,螺线管与滑动轮,所述滑动轮的左端固定连接有固定转轴,固定转轴上开设有限位槽,固定转轴的外部设置与轴套,轴套的内部设置有螺线管,螺线管的下方设置有铁块,铁块的下面固定连接有限位件。螺线管外部线圈断电,断电后的螺线管对铁块不具备磁力吸引,从而铁块随着限位件在复位弹簧的作用下移动,复位弹簧的弹力使得限位件进入限位槽中,从而使得固定转轴与轴套连接在一起,滑动轮不能转动,从而在滑动轮与地面滑槽的摩擦力的作用下使行车主体的惯性力被抵消,行车主体得以停下来以避免碰撞,从而达到了强制使行车停下来的效果。
