The invention discloses multi-stage material lifting equipment with a safe self-locking function, and relates to the technical field of lifting equipment, the multi-stage material lifting equipment comprises a mounting frame, a first-stage telescopic frame, a second-stage telescopic frame, a small tackle and a driving winding drum, two first mounting grooves are symmetrically formed in the mounting frame, and positioning plates are arranged in the two first mounting grooves; one end of the positioning plate is fixedly connected with a first sliding plate. Through cooperative use of a positioning plate, a positioning groove, a connecting rope and a first spring, when a user opens a driving winding drum to drive a small tackle to ascend, and when a first-stage telescopic frame drives the positioning groove and the positioning plate to be located at the same horizontal height, the first spring drives a first sliding plate and the positioning plate to rebound at the moment; according to the self-locking device, the positioning plate can enter the positioning groove, self-locking of the first-stage telescopic frame is completed through the positioning plate, pressure borne by the steel wire rope can be reduced, the safety of the device is improved, and meanwhile the safety of the device can be guaranteed through self-locking of the positioning plate.
本发明公开了一种具有安全自锁功能的多级物料升降设备,涉及升降设备技术领域,包括安装架,一级伸缩架,二级伸缩架,小滑车,驱动卷筒,安装架内部对称开设有两个第一安装槽,两个第一安装槽内部均设有定位板,定位板一端固定连接有第一滑板。本发明通过定位板、定位槽、连接绳以及第一弹簧的配合使用,当用户通过打开驱动卷筒带动小滑车进行上升时,当一级伸缩架带动定位槽与定位板处于同一水平高度时,此时第一弹簧带动第一滑板和定位板进行回弹,从而使得定位板能够进入定位槽的内部,从而通过定位板完成对一级伸缩架的自锁,从而能够减少钢丝绳受到的压力,进而提高设备的安全性,同时通过定位板的自锁也能够保证设备的安全性。
