The invention discloses a main hoisting mechanism of a material sucking and discharging crown block, the main hoisting mechanism of the material sucking and discharging crown block comprises a base, a first supporting plate is arranged on the upper surface of the base, a safety box is arranged on the upper surface of the first supporting plate, and a first through hole is formed in the safety box; and a sliding rod is slidably connected into the first through hole. According to the main hoisting mechanism of the material sucking and discharging crown block, through matched arrangement of a sliding rod, a limiting baffle, an electromagnetic iron ring, a first spring, a clamping block and a limiting block, when a winch braking system is powered off, the electromagnetic iron ring is powered off, then magnetism disappears, under the elastic force effect of the first spring, the limiting baffle is pushed to slide, the limiting block is extruded, and the limiting baffle is clamped by the limiting block; and meanwhile, the limiting baffle abuts against the rotating shaft rod, and the rotating shaft rod is braked under the action of the clamping block, so that the effect of reducing safety accidents is achieved, and the purpose of improving the use safety is achieved.
本发明公开了一种吸卸料天车主起升机构,本发明一种吸卸料天车主起升机构,包括底座,所述底座的上表面设置有第一支撑板,所述第一支撑板的上表面设置有安全箱,所述安全箱的内部开设有第一通孔,所述第一通孔的内部滑动连接有滑杆。该吸卸料天车主起升机构,通过滑杆、限位挡板、电磁铁环、第一弹簧、卡块和限位块的配合设置,当卷扬机制动系统断电时,电磁铁环断电,进而使磁性消失,在第一弹簧的弹力作用下,推动限位挡板滑动,挤压限位块,使限位块卡住限位挡板,同时使限位挡板抵接到转动轴杆上,在卡块的作用下,对转动轴杆进行制动,从而起到了减少安全事故发生的作用,达到了提到使用安全性的目的。
