这个翻转吊钳(图1)是太原重型机器厂工人创制的。它可以吊运直径在1.2米重6吨以下的工件,结构也很简单,由于钳口可以自动张开和钳住工件,所以大大地改善了劳动条件,使工人摆脱了繁重的体力劳动,减轻了高温的威胁。 这个吊钳主要是利用杠杆原理,现将其结构简要介绍如下.支撑板使 This overturning tong (Figure 1) was created by a Taiyuan heavy machinery factory worker. It can lift the diameter of 1.2 meters in weight 6 tons below the workpiece, the structure is also very simple, because the jaws can be opened automatically and clamp the workpiece, so greatly improve the working conditions, so that workers get rid of the heavy manual labor, reduce The threat of high temperatures. This tong is mainly the use of lever principle, the structure is now briefly described as follows.
