The invention relates to an anti-falling device for a lifting material box of a material elevator. The material elevator comprises a vertical outer frame, the lifting material box which is movably arranged in the vertical outer frame, and a safety door which is rotationally arranged on the vertical outer frame. The anti-falling device comprises an outer frame fixing base arranged on a stand columnof the vertical outer frame, a bent plug pin rod rotationally connected with the outer frame fixing base, and a transmission connecting rod with the two ends hinged to a transmission rod and the safety door respectively. Compared with the prior art, the anti-falling device for the lifting material box of the material elevator is simple in structure and easy to operate. An anti-falling function isstarted while the safety door is opened through the linkage effect between the safety door and the bent plug pin rod, and the safety of the whole equipment is guaranteed. In addition, the anti-falling device for the lifting material box of the material elevator is few in parts, low in production and manufacturing cost and maintenance cost, small in size, capable of being effectively suitable forvarious production environments with narrow spaces, and wide in application prospect.
本发明涉及一种物料提升机升降料箱防坠落装置,其中物料升降机包括立式外框架、移动设于立式外框架内的升降料箱,以及转动设于立式外框架上的安全门,防坠落装置包括设于立式外框架的立柱上的外框架固定座、与外框架固定座转动连接的弯折插销杆,以及两端分别与传动杆及安全门相铰接的传动连杆。与现有技术相比,本发明结构简单、易于操作,通过安全门与弯折插销杆之间的联动作用,使得在安全门开启的同时,即启动防坠落功能,保证了整体设备的安全性;此外,本发明零部件较少、生产制造成本及维护成本较低、体积较小,可有效适用于多种空间狭窄的生产环境,具有较为广阔的应用前景。
