我厂在制造化工容器时,需经常吊装圆筒形工件、封头及中厚钢板,过去一直是用螺旋弓形夹吊具,吊装起来既不方便又不安全。后我们参考有关资料,设计了一种起重自紧吊钳,经过近两年的使用证明,此吊具操作方便,安全可靠,效果很好,很有推广价值。吊钳由钳钩1、夹紧板2、销轴3和4、吊环5、开口销6和7组成,见附图。钳钩1是用两块同样的钩板与中间两块连接板焊接而成的。钳钩1与夹紧板2的工作面开有小齿,是用来增加摩擦力的。操作时钳口朝下并套在工件上,工件比较重时,对称使用两个
I plant in the manufacture of chemical containers, the need to constantly lifting cylindrical workpieces, head and plate, in the past has been the use of spiral bow clamp spreader, lifting up neither easy nor safe. After we refer to the relevant information, we designed a lifting self-tight hanging clamp, after nearly two years of use proved that this spreader is easy to operate, safe and reliable, the effect is very good, great promotional value. Clamp clamp by the clamp 1, clamping plate 2, the pin 3 and 4, rings 5, cotter 6 and 7 components, see the accompanying drawings. The clamp hook 1 is welded with two identical hook plates and two middle connection plates. The clamp hook 1 and the clamping plate 2 are provided with small teeth on the working face to increase the friction. Operated when the jaws down and set on the workpiece, the workpiece heavier, symmetrical use of two
