The invention relates to a material gripping apparatus with a device for automatically adjusting the sectional area, which aims to overcome the defects that round materials with different loading and unloading diameters are bound and hoisted by steel wire ropes or other ropes and are easy to wear, the loading and unloading efficiency is low, the labor intensity of workers is high, people and goods are not separated, the safety is unsafe and the like. The gripping apparatus can be assembled on engineering machinery, an external control valve is used for controlling the 360-degree rotator of the gripping apparatus to rotate and the hydraulic oil cylinders of the gripping arms to stretch out and draw back, and the material loading and unloading direction of the gripping apparatus and the opening and closing of the gripping arms of the gripping apparatus can be adjusted at will. An adjusting device frame hydraulic oil cylinder, an adjusting device frame and a gripping apparatus vertical frame which are assembled on the gripping apparatus form an automatic sectional area adjusting device, an external control valve is used for controlling the device frame hydraulic oil cylinder to stretch out and draw back, and the adjusting device frame is adjusted to be folded and unfolded at will, so that the sectional area of the gripping apparatus in a closed state is adjusted. The gripping apparatus can effectively solve the problem of circular materials with different diameters, and is simple in structure, convenient to use, low in labor intensity of workers, safe and reliable, and people and goods are separated.

    一种配有自动调整截面积大小装置的物料抓具,是为克服装卸直径尺寸不同的圆形物料用钢丝绳或其他绳索捆绑吊装易被磨损,装卸效率低,及工作人员劳动强度大、人货不分离、不安全等缺点提供的。本抓具可装配在工程机械上,利用外接的控制阀,控制抓具360°旋转器转动和爪臂液压油缸伸缩,可任意调节抓具装卸物料方向和抓具爪臂的张开、闭合。抓具上装配的调节装置架液压油缸、调节装置架与抓具立架构成自动调整截面积大小装置,利用外接的控制阀,控制装置架液压油缸伸缩,任意调节调节装置架收放,以此来调整抓具闭合状态时截面积的大小,可有效解决直径尺寸不同的圆形物料,抓具结构简单,使用方便,工作人员劳动强度低,人货分离,安全可靠。
