The invention relates to a gripping apparatus with an anti-falling device for engineering machinery, which aims to overcome the defects that the conventional gripping apparatus is inconvenient to load and unload cylindrical materials (such as logs) with different lengths, is hung and bound by a steel wire rope or other ropes, is easy to wear in the hoisting process, is easy to fall off and is inconvenient to use. The labor intensity of workers is large, people and goods are not separated, safety is not achieved, and the work efficiency is low. The gripping apparatus is provided with a hydraulic rotating device which is controlled by an external hydraulic control valve, so that the gripping and unloading directions of the gripping apparatus can be freely and automatically adjusted; the gripping apparatus is provided with the heavy plate type chain, and finally, when the gripping apparatus is used for gripping several log materials with smaller diameters in a closed manner, the mounted heavy plate type chain can effectively press the materials without displacement by utilizing the self weight of the heavy plate type chain, so that the effect of preventing the materials from falling off is achieved, and safety accidents such as slipping and falling off of the materials in the unloading process are avoided. The device is simple in structure, convenient to use, low in personnel labor intensity, high in efficiency, safe and reliable, and people and goods are separated.

    一种工程机械用带有防脱落装置的抓具,是为了克服现有装卸长度不一的圆柱形物料(如原木等物料),用钢丝绳或其他绳索兜吊、捆绑不方便,且在吊装过程中容易被磨损,圆柱形物料易滑落,以及工作人员劳动强度大、人货不分离、不安全及工效低的缺点所提供的;抓具装配液压旋转装置,利用外接的液压控制阀控制,可任意自动调整抓具的抓取和卸放方向;抓具安装有有重型板式链条,最后在使用抓具闭合抓取几根直径较小的原木物料时,安装的重型板式链条可利用其自身重量有效的压住物料不移位,起到了防止物料脱落的作用,避免物料在卸放过程中发生滑落、脱落等安全事故。本发明结构简单,使用方便,人员劳动强度低,效率高,人货分离,安全可靠。
