    摘要:

    為研究山地果園鏈?zhǔn)窖h(huán)貨運索道負載數(shù)量、張緊位置、掛載方式及驅(qū)動電動機工作頻率等因素對驅(qū)動鏈張緊力的影響,設(shè)計了一種用于檢測山地果園鏈?zhǔn)窖h(huán)貨運索道驅(qū)動鏈張緊力的試驗裝置。試驗結(jié)果表明:除驅(qū)動電動機工作頻率外,其他三因素對驅(qū)動鏈張緊力影響顯著;將張緊機構(gòu)置于起始位置與終端位置以及改變負載數(shù)量,檢測得張緊力均值差異變化范圍為105.929~164.641N;將張緊機構(gòu)置于起始位置,采用均衡和非均衡兩種掛載方式,張緊力均值變化范圍為1.165351~1.425864N和1.140500N~1.435353N,相應(yīng)的變異系數(shù)變化范圍為0.115~0.139和0.155~0.227。

    Abstract:

    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.
