The invention relates to the technical field of freight, and discloses a freight hoisting device facilitating automatic grabbing and putting down to improve hoisting efficiency. The freight hoisting device comprises a winding shaft, the front surface of the winding shaft is fixedly connected with a rotating disc, the rotating disc is internally provided with a sliding groove, and the bottom of the interior of the sliding groove is fixedly connected with a connecting spring. According to the freight hoisting device facilitating automatic grabbing and putting down to improve the hoisting efficiency, when the paying-off speed is too high, limiting rods are clamped by fixing clamping grooves at the moment, the rotating speed of the winding shaft is further stopped, and therefore the effect of avoiding rope breakage caused by the too high paying-off speed is achieved. When grabbing is conducted, an electromagnetic device is powered off, at the moment, the left side and the right side of goods can be fixed through clamping jaws, after the goods are hoisted to a proper position, the electromagnetic device is powered on, an electromagnetic balancing weight moves upwards, the clamping jaws release grabbing of the goods, and therefore the effects that automatic grabbing and putting down are conveniently achieved, and the hoisting efficiency is improved are achieved.
本发明涉及货运技术领域,且公开了一种便于自动抓取放下提高吊运效率的货运吊装装置,包括绕线轴,所述绕线轴的正面固定连接有转动盘,所述转动盘的内部设置有滑槽,所述滑槽内部的底部固定连接有连接弹簧。该便于自动抓取放下提高吊运效率的货运吊装装置,放线速度过快时,此时限位杆被固定卡槽卡住,进一步使得绕线轴的转动速度会停止,从而达到了避免放线速度过快导致绳索断裂的效果。进行抓取时,将电磁装置断电,此时卡爪可以对货物的左右两侧进行固定,吊运到合适位置后,给电磁装置通电,此时电磁配重块向上运动,进一步使得卡爪放开对货物的抓取,从而达到了便于实现自动抓取和放下提高吊装效率的效果。
