Seethesectionentitled‘EditDrawWorksDataMenu’forafullbreakdownofthemenustructure. 察看这个标有”editdrawworksdatamenu”的单元中细目分类 1)CoilsperLayer:

指绞盘上每一层的缆绳圈数,既可以将所有层设置为统一的一个值,也可以对每一个层进行单独设置.若要对每一个层进行单独设置,则一定要注意,“layer1”与在选项3)中使用的缆圈所处的层相一致.为了提高精度,可以试着在此次测量中包含部分缆圈. 2)RopeDiameter Diameteroftheropeshouldbemeasuredeitherusingcallipersorbywrappingapieceofstringaroundtheropebyanumberofcompleteturns,measuringthelengthandusingthefollowingformula: 可以使用测径规测量大绳的直径.或将一截绳子缠绕在大绳上,数出完整的圈数,并该圈数的绳子所对应的长度,然后通过以下公式计算大绳的直径 RopeDiameter=length/turns/PI 大绳直径=长度/圈数/pi 3)Layer1coillength第一层的线圈长度 Thisisthelengthofonecoilonthefirst(bottom)layerofropeonthedrum.Ifthebottomlayerisnotaccessibleformeasurementthenthelayertreatedaslayer1shouldbethelowestlayerthatiseverused,iethelayerthatispartiallyunwrappedwhenthetravellingblockisatitslowestpossibleposition.Itisveryimportantthatthelayerchosenwillneverbefullyunwoundfromthedrum.Thelengthshouldbemeasuredbymarkingtwoadjacentcoilswithchalk,spoolingthosecoilsoffthedrumandmeasuringthedistancebetweenthetwochalkmarks.Ifthisisnotpossibleandtheactualdrumdiameterisknownthelayer1coillengthcanbecalculatedasfollows: 这是指在缆盘最底部那一层一圈缆绳的长度.如果无法对最底层缆绳进行测量,那么将使用过的缆绳中处于最底层的那一层作为第一层.例如: 当滑动绞车位于其最低位置时,大绳被部分松开的那一层.必须注意的是,所选的那一层永远不会完全从缆盘上被松开.用粉笔在两个相邻的线圈之间进行标注,将这些线圈从缆盘上松开,测量这两个标志之间的距离.如果无法完成上述过程,且实际的缆盘直径已知,那么第一层的线圈长度可以通过以下公式进行计算: Layer1coillength=(drumdiameter+ropediameter)*PI 层1缆圈的长度=(缆盘直径+大绳直径)*pi Measuringthedistancebetweenthetwoadjacentchalkmarkscanbeachievedbyusingadhesivetapetosecureatapemeasureatthefirstchalkmarkthenloweringthetravellingblockuntilthesecondchalkmarkisjustoffthedrum. 对相邻两个标记间距离的测量可以通过以下方式实现: 用粘性胶带将一个皮尺固定在第一个标志处,然后使绞车向下移,直到第二个标记刚刚脱离缆盘为止. 4)Linesinderrick Thisisthetotalnumberoflinesrunningbetweenthetravellingblockandthecrownblock,ie: 这是指在滑动绞车和定滑轮之间的总缆线数.例如: Linesinderrick=Numberofsheavesintravellingblock*2 钻塔上的缆线数=在绞车上的线数*2 5)RotarySensor旋转传感器 |----------------------------------------| |******* countsperrev–每一转所计树值 |1)CountsperRev|selectdirection–方向的选择

在为止的情况下,可通过以下方法进行测量: 将传感器上相对于外部(固定部分)的中心部位标注出来,然后将传感器完整的旋转一圈,观察在深度跟踪主页面上显示的旋转计数值. 由于DTU传感器能够感应旋转传感器输出信号的上跳沿和下跳沿,则所需的数值也许是生产商所提供数值的两倍 2)Selectdirection

传感器中原始的计数值会随着绞车的上移或下移而增加,这取决于在绞盘上的传感器的方向.确定该设定是否正确的最简单的方法是,在绞车运动的情况下,检查深度跟踪主页面上所显示的绞车的移动方向.如果该设定是不正确的,则设置为相反的方向. c)SetDrawWorksReferencePoint设置绞车参考点
