摘 要:为研究山地果园链式循环货运索道负载数量、张紧位置、挂载方式及驱动电动机工作频率等因素对驱动链张紧力的影响,设计了一种用于检测山地果园链式循环货运索道驱动链张紧力的试验装置。试验结果表明:除驱动电动机工作频率外,其他三因素对驱动链张紧力影响显著;将张紧机构置于起始位置与终端位置以及改变负载数量,检测得张紧力均值差异变化范围为105.929~164.641 N;将张紧机构置于起始位置,采用均衡和非均衡两种挂载方式,张紧力均值变化范围为1 165.351~1 425.864 N和1 140.500 N^1 435.353 N,相应的变异系数变化范围为0.115~0.139和0.155~0.227。For studying effects of different combinations of influential factors including payload variations,tension locations,loading approaches and motoring frequencies the circular chain cargo transportation ropeway imposes on the driving-chain in mountain orchards,a related device added to the ropeway system was designed to detect real-time dynamic variations for driving-chain tensions.The experimental results indicated that effects from the other three factors on the hoisting chain tension were obvious except for that from the motoring frequency.While the mechanical operator was adjusted to various locations,exclusively at the start and at the terminal,differences of mean tension variations were obtained ranging from 105.929N to 164.641N under different payloads.In addition,when the mechanical operator was adjusted to the commencing point,through either balanced loading or unbalanced loading approaches,mean tension variations were obtained ranging from 1165.351N to 1425.864N and 1140.500N to 1435.353N with related variation coefficients from 0.115 to 0.139 and 0.155 to 0.227,respectively.
