建设矿山开凿竖井时,机械设备和井架都可在标准图册中查找,而用以悬吊设备的钢绳的天轮托梁及其布置,各矿都有自己独特的设计。我国开凿竖井通常是采用多钢绳提升方案,天轮数目多达30余个,大小托梁也有30多条,总用钢量接近10吨。因此安全经济地设计天轮托梁是引起大家重视的问 When constructing a mine to excavate a shaft, mechanical equipment and derricks can be searched in the standard atlas, and the sky wheel joists and their arrangement for the suspension ropes of the ropes have their own unique designs. In China, the use of multi-rope hoisting schemes is usually used to drill shafts in China. There are more than 30 days for the number of days and more than 30 for large and small joists. The total amount of steel used is close to 10 tons. Therefore, it is a question that everyone pays attention to safely and economically designing the wheel joists.
