起重吊钩的作用
发布时间:2023-01-05        浏览次数:92        返回列表

起重吊钩,是一种起重机的部件。常用于起吊重物。起重机的吊钩是起吊重物的主要零件,它除了承受吊重以外,还要承受起升机构起动和制动时的冲击载荷。因此,制造吊钩用的材料都应具有较高的强度和冲击韧性,其安全系数也比较大。吊钩虽然只对起重机起辅助作用,但起着非常重要的作用。它们的搭配大大提高了工作效率。而且这个结构很简单,工作原理也很简单。吊钩一般也是小巧玲珑。吊钩组有两种类型,长钩组和短钩组,长钩组使用短钩,其滑轮轴在上面,钩梁在下面.拉板平行安装。单双动滑轮数量均可,钩梁短,受力好。卷简长度相应较短。短吊钩组的滑轮轴也是吊钩梁,省去了拉板,但滑轮数量要对称。用长钩旋转时不碰滑轮。但是吊钩组的整体高度较小。吊钩广泛用于:大中型工厂、货运码头、物流园区、矿山矿场、桥梁工程建设、建筑工程等诸多行业。The lifting hook is a component of a crane. It is often used for lifting heavy objects. The hook of the crane is the main part for lifting heavy objects. It not only bears the lifting load, but also bears the impact load when the hoisting mechanism starts and brakes. Therefore, the materials used for manufacturing hooks should have high strength and impact toughness, and their safety factors are relatively large. Although the hook only plays an auxiliary role for the crane, it plays a very important role. Their combination greatly improves the work efficiency. And the structure is very simple, and the working principle is also very simple. The hook is generally small and exquisite. There are two types of hook groups, long hook group and short hook group. The long hook group uses a short hook, with the pulley shaft above, the hook beam below, and the pull plate installed in parallel. Both single and double acting pulleys are available, with short hook beam and good stress. The reel length is relatively short. The pulley axis of the short hook group is also the hook beam, which eliminates the pulling plate, but the number of pulleys should be symmetrical. Do not touch the pulley when rotating with a long hook. However, the overall height of the hook group is small. The hook is widely used in many industries such as large and medium-sized factories, freight terminals, logistics parks, mines and mines, bridge engineering construction, and construction engineering.
