Description

一种多杆机构输送机的工作方法 技术领域
本发明涉及运输船输送机技术领域，特别是涉及一种多杆机构输送机的工作方法。
背景技术
近年来，内河卸沙船以其卸装货物灵活快速的优势受到了广泛关注，然而其不稳定问题也是日益突出。而且，我国水域广阔，水运资源丰富，内河自卸砂船应用普遍，其产业也正处于蓬勃发展期。但是，传统的自卸砂船的输送臂架可达40米以上，但往往不能回收，导致稳定性差，存在极大的安全隐患。比如：因传统外伸式皮带架事故发生率太高，国内保险公司曾出现过联合为皮带架拒保的情况。
因此，为解决输送臂架回收的技术难题，国内先后出现了伸缩式、旋转式、折叠式等多种解决方案。
专利号为201610594201.8，名称为一种自适应的整体翻转式输送机的公开发明专利，提出了一种利用双筒卷扬机和整体桁架式臂架，然后利用双筒卷扬机拉动输送臂架折叠的输送技术方案；该方案一定程度上解决了占用船体空间问题，以及其整体翻转形式，使其折叠翻转的形式操作更简便，且卸砂时臂架安全性更高。但是由于其使用整体桁架式臂架，其长度是固定的，输送距离不可以控制，整体翻转形式会比折叠翻转的形式操作更简便，可是翻转后输送臂处于空中，固定性不强，会存在极大安全隐患。
专利号为201610728114.7，名称为一种输送臂可伸缩的输送机的公开发 明专利，提出了一种利用多级液压油缸和剪刀叉机构，然后利用多级液压油缸来实现剪刀叉机构的收缩，从而实现输送臂可伸缩。该方案一定程度上解决了在收放时对船体的平衡性能影响小，可伸出距离大，收放效率高，工作时平稳，安全性高。但是多杆机构比剪刀叉机构工作更加稳定，可伸出距离更大，单元式的展开比多级液压油缸更加安全，无张紧机构，而且更加便与生产与组装。
发明内容
本发明的目的是提供一种多杆机构输送机的工作方法，解决自卸沙船在非工作状态时占用空间过大、回收操作复杂以及现有技术存在的龙门架结构复杂、输送臂架自重超重、输送臂长度不足、安装调试复杂、不能自动控制、缺乏安全保护装置等问题，从而降低制与维护成本，提高使用自动化与安全性。
