Description

钢丝绳自动换向排线装置 技术领域
本发明创造涉及一种 钢丝绳自动换向排线装置 ，特别是一种在 绳筒上卷绕多层钢丝绳的自动换向排线装置 。
背景技术
众所周知，在电动葫芦、提升机、卷扬机、各种室内外吊机以及电动绞盘等各种吊重设备上都配有钢丝绳绳筒，为了缩小绳筒体积，钢丝绳都以多层方式卷绕在绳筒上。人们对所购的吊重设备在不减功能的前提下，希望钢丝绳使用寿命更长，同时在使用时不管是空载还是负载要求钢丝绳卷绕不能杂乱排序、相互挤压，同时 要求钢丝绳换向时不能有爬坡后发生的剧烈响声。
 技术问题
但现有市场上供应的各种多层钢丝绳绳筒的吊重设备，在使用过程中存在以下不足之处：一是压线机构不合理，在钢丝绳卷绕过程中极易产生缠绕、乱层和挤压现象，造成钢丝绳互相挤压损伤，严重影响了钢丝绳的使用寿命。二是在钢丝绳换向时经常出现爬坡现象，爬坡后发生剧烈响声，不仅大大缩短了钢丝绳的使用寿命，而且还会产生一种恐慌感。 解决这一缺陷的关键是使钢丝绳在每层能依次整齐、紧凑排列。针对上述问题，许多生产厂家和有识之士投入了大量的人力和物力进行开发和研制，但至今尚未有较 理想的产品面世。
技术解决方案
为克服现有多层 钢丝绳绳筒在钢丝绳卷绕过程中 存在的上述缺陷，本发明创造的目的是提供一种结构简单合理、拆装使用方便、换向安全可靠、排列紧凑整齐、使用寿命长的钢丝绳自动换向排线装置。
本发明创造解决上述技术问题所采用的技术方案，它包括罩壳、转轴、绳筒、钢丝绳、换向排线架、换向机构和压线机构，绳筒设置在转轴上，换向排线架固定在罩壳上，所述的换向排线架上至少设有一个换向机构，该机构包括换向轮轴和换向轮，换向轮轴可水平移动的固定在换向排线架上，换向轮位于绳筒的下方并可转动的设置在换向轮轴上，钢丝绳在换向时与换向轮滚动接触，并在换向轮的导向下向绳筒中心偏转β角，β角控制在5至8度之间。
本发明创造的进一步方案，所述压线机构包括左右压力调节固定套、压簧、左右压力调节活动套、左右调节座、防松压辊，左右压力调节固定套对应固定在换向排线架上，左右压力调节活动套对应套设在左右压力调节固定套上，压簧对应设置在左右压力调节活动套与左右压力调节套之间，左右调节座对应固定在左右压力调节活动套上，防松压辊可转动的设置左右调节座上，防松压辊把钢丝绳紧压在绳筒上。
本发明创造的更进一步方案，所述的绳筒表面设有螺旋槽，在绳筒的钢丝绳出线孔上设有钢丝绳过渡镶块。
本发明创造的更进一步方案，所述的换向轮上设有25至30度的斜度。
 有益效果
采用上述结构后， 与现有技术相比有如下优点和效果：一是由于在绳筒下方设置钢丝绳换向机构，在钢丝绳换向时换向轮使钢丝绳向绳筒中心偏转一定角度，使钢丝绳自然过渡达到可靠换向的目的，并在压线机构的共同作用下保证钢丝绳在每层都能排列有序、紧凑，避免了不规则的挤压损伤，从而提高钢丝绳的使用寿命。 二是解决了由于安装不水平造成的换向难的问题。三是解决了现有的部份排线器只能单向运转换向或单层钢丝绳运行的限制。 四是由于绳筒表面设有螺旋槽，在绳筒的钢丝绳出线孔上设有钢丝绳过渡镶块，解决了由下限位装置带来的钢丝绳出口有缠绕空缺的不足。五是压线机构和换向机构整合在一起，拆装方便，换向更加可靠，同时便于运输。
