The invention relates to the technical field of automobile part machining equipment, and discloses a lifting equipment stall protection device for automobile part machining. The device comprises an equipment supporting frame and a transport flat plate, wherein a limiting plate is fixedly connected to the inner side of the equipment supporting frame, a driving rotary shaft is movably connected into the limiting plate, a rotary disc is fixedly connected to the top of the driving rotary shaft, and long sliding grooves which are uniformly distributed are formed in the rotary disc. According to the lifting equipment stall protection device for automobile part machining, when the transport flat plate ascends or descends too fast due to stall in the lifting process, centrifugal force generated during rotation of the rotary disc is larger than tensile force of a traction spring, a movable contact is thrown out to make contact with a fixed contact, an electromagnet is electrified to have magnetism at the moment, an elastic limiting bag is pushed out and deformed to be clamped and fixed to the equipment supporting frame; and meanwhile, an external electric field is switched on, so that electrorheological fluid is changed to be in a solid state from a liquid state, the transport flat plate is fixed, and an accident caused by stall of the transport flat plate is prevented.
本发明涉及汽车零件加工设备技术领域,且公开了一种汽车零件加工用升降设备失速保护装置,包括设备支撑架和运输平板,所述设备支撑架内侧固定连接有限位板,限位板内部活动连接有驱动转轴,驱动转轴顶部固定连接有转动盘,转动盘内部开设有均匀分布的滑动长槽。该汽车零件加工用升降设备失速保护装置,当运输平板升降过程中出现失速导致过快上升或者下降的情况时,转动盘转动产生的离心力大于牵引弹簧的拉力,动触头被甩出,与定触头接触,此时电磁铁通电具有磁性,将弹性限位囊推出,使得弹性限位囊变形与设备支撑架卡接固定,同时接通外加电场,使得电流变液从液态变为固态,将运输平板进行固定,防止其由于失速导致事故。
