The invention discloses a metro construction lifting anti-falling structure which comprises a horizontally arranged electromagnet, grooves are formed in the left side and the right side of the electromagnet, two vertical plates are fixedly connected to the top of the electromagnet, the two vertical plates are symmetrically arranged front and back, and a transmission rod is arranged between the two vertical plates in a penetrating mode. According to the device, through mutual cooperation of the air cylinders, the circular rings, the transverse rods, the linkage blocks, the clamping blocks, the connecting shafts, the electromagnets, the travel switches, the lifting plates, the translation plates and other components, when the hopper is in contact, the clamping blocks are driven to rotate, the clamping blocks are driven to rotate, and the clamping blocks are driven to rotate; and when the lifting plate makes contact with the hopper, the travel switch can be triggered, the air cylinder can be started by the travel switch to drive the multiple clamping blocks to move, and therefore secondary clamping on the hopper is achieved, and the stability of the hopper in the operation process is improved.
本发明公开了一种地铁施工吊运防脱落结构,包括水平设置的电磁铁,所述电磁铁左右两侧均开设有凹槽,所述电磁铁顶部固定连接有两个竖板,且两个所述竖板为前后对称设置,两个所述是竖板之间共同贯穿设有传动杆,所述传动杆外侧固定套接有辊轮,且所述辊轮位于两个竖板之间,两个所述竖板之间共同固定连接有两个横板,本发明通过气缸、圆环、横杆、联动块、夹块、连轴、电磁铁、行程开关、升降板、平移板等部件之间的相互配合,可实现接触到料斗时,可对料斗进行吸附,对料斗进行初步夹持,当升降板与料斗进行接触时,可触发行程开关,行程开关可启动气缸带动若干夹块进行活动,从而实现对料斗进行二次夹持,提高料斗运行过程的稳定性。
