The invention relates to a round steel vertical lifting appliance with an anti-pinch-breaking protection structure. The appliance comprises a lifting chain and a plate eave groove, a lifting lug is arranged at the bottom end of the lifting chain, a pin shaft is arranged at the end of the lifting lug in a penetrating mode, a spacer bush is arranged at the side end of the pin shaft, a reinforcing plate is installed at the end of the spacer bush, the plate eave groove is formed in the side end wall of the reinforcing plate, a pin fixing mechanism is arranged at the inner side end of the plate eave groove, and a locking mechanism is installed at the bottom end of the pin fixing mechanism. The round steel vertical lifting appliance has the beneficial effects that the round steel vertical lifting appliance with the anti-pinch-damage protection structure can be in threaded transmission with the screw rods by rotating the nut columns, so that the two screw rods rotate and generate displacement, and when the screw rods protrude out of the end wall of the plate fixing seat, the screw rods can be attached to the end wall of a plate eave groove, locked and positioned; at the moment, the plate fixing seat can be stably fixed to the end of the reinforcing plate for linkage use, and when the plate fixing seat is used at the same time, small cylindrical structures such as steel bars can be inserted into the pin holes, nut columns are shifted, and the nut columns are rotated and regulated.

    本发明涉及一种具有防夹破保护结构的圆钢竖起吊具,包括吊链和板檐槽,所述吊链的底端安置有吊耳,且吊耳的端部穿设有销轴,所述销轴的侧端安置有隔套,且隔套的端部安装有加强板,所述板檐槽开设于加强板的侧端壁,且板檐槽的内侧端安置有固销机构,所述固销机构的底端安装有锁合机构。本发明的有益效果是:该具有防夹破保护结构的圆钢竖起吊具,通过旋转螺母柱可与螺杆之间进行螺纹传动,使两个螺杆进行旋转,并产生位移,当螺杆凸出固板座端壁后,可与板檐槽端壁贴合,锁定定位,此时固板座可稳定的固定在加强板端部,进行联动使用,同时使用时,可将钢条等小圆柱状结构插入柱销孔,拨动螺母柱,使螺母柱进行转动调控。
