一钢平改转方坯连铸机工程,中间罐吊具是用于中间罐的调运,中间罐的4个吊耳不是完全对称,而且在满负荷时有70余吨,调运过程中一定要做到安全可靠。在设计之前,考察了许多钢厂,它们设计中间罐吊具的结构有许多种,但吊钩的形式只有开式和闭式两种。开式结构吊运时简单,容易进钩和脱钩,但是体积较大,调运时要求的空间位置较大。闭式吊钩体积小、重量轻,但调运过程中需要派专人挂钩,对钩子的灵活程度要求较高。一钢厂的中间罐安装了塞棒系统后,相对调运位置很小,根本不允许安装开式吊钩,但闭式吊钩缺点较多。在这种情况下,笔者考虑了一种结构是吊钩采用闭式结构,和钩子连接的是锚链、卸扣,这样就避免了以上两种钩子的缺点。现在我们对钩子(卡套)、销轴、
A steel flat turn billet continuous casting machine project, the middle canister spreader is used for the transfer of the intermediate tank, the middle of the four lugs is not fully symmetrical, but at full load more than 70 tons, the transfer process must be Be safe and reliable Before the design, many mills were inspected, and there were many kinds of structures for designing the middle tank spreader, but the form of the hook was only open and closed. Open structure Lifting is simple, easy to enter the hook and decoupling, but the larger, the space required for transfer location. Closed hook small size, light weight, but the transfer process needs to send someone hook, the flexibility of the hook higher requirements. After the installation of a stopper rod system in the middle tank of a steel mill, the relative transfer position is very small, open hooks are not allowed at all, but the closed hooks have more disadvantages. In this case, I consider a structure is hook closed structure, and the hook is connected to the chain, shackle, thus avoiding the shortcomings of the above two hooks. Now we hook (card sets), pin,
