胎带机布料臂架伸缩机构钢丝绳设计技术研究

The Design Technology Study of Wire Rope in Telescopic Mechanism for Placing Boom of Belt Conveyor

胎带机是一种具有多用途、移动式、可连续输送物料的物料输送设备,动作灵活、作业范围大、适应性强,已广泛应用于水利水电、码头等大型混凝土浇筑工程中。以50m胎带机为研究对象,对其布料臂架伸缩机构中的钢丝绳预紧力及其在工作载荷情况下克服摩擦力等阻力所需要的拉力进行了分析研究,并确保钢丝绳正常工作,即钢丝绳需满足强度、挠度条件,且满足不打滑条件。根据分析计算结果,选择适当的钢丝绳直径,保证布料臂架正常稳定经济运行。该研究结果对其它类似产品中钢丝绳的设计具有指导性意义。

Belt Conveyor is a multi-purpose, mobile, and can convey the material continuously equipment, which has a lot of advantages, such as ,flexible operation, large operating range, strong adaptability and so on, has been widely used in water conservancy and hydropower, wharf and other large concrete engineering.It takes the 50m large scale belt conveyor as the research object, in which, the wire ropes in telescopic mechanism for placing boom are studied and analyzed. The wore ropes pretigteningand tension,which is to over come the friction while the placing boom is working, should to ensure the boom can work normally, namely the wire rope should meet the requirements of strength,flexibility, and the non slip condition. Finally, according to the results ,select the appropriate diameter of the steel wire rope to ensure the boom can operate normally, stably and economically. The results of this study have guiding significance for the design of wire rope in other mechanical products.
