Description
本申请要求于2021年12月6日提交中国专利局、申请号为202111478183.4、申请名称为“双层联动闭环绳系安装方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
本发明涉及一种双层联动闭环绳系安装方法。
电动舱门是用于实现货物自动出舱功能的关键单机，其密封性能和开关性能直接关系到型号功能的实现。绳系机构作为舱门滑移传动机构组成部分，由电机驱动牵引舱门沿预定轨迹在打开和关闭位置之间运动。
绳系机构的双层联动闭环绳系包括上、下两层芳纶绳缠绕绳系，每层绳系两端分别固定在驱动轮组件和缠绕轮组件的上、下轮外表面压板上，并通过绳槽底部穿绳孔在绳槽内缠绕不同圈数。在初始安装状态，驱动轮组件上轮和缠绕轮组件下轮绕绳5圈，驱动轮组件下轮和缠绕轮组件上轮绕绳3圈。下层绳系为一根绳。上层绳系为两根绳，另一端分别固定在牵引点组件盖板上，并通过两个小缠绕座绳槽底部穿绳孔在绳槽内绕绳3圈。要求所有绳槽内的绳圈均为单层叠加，不并排、不交叠，因此，绳系机构的绕绳装调是一大难题。
由于驱动轮组件和缠绕轮组件的上下两层轮均为刚性连接，故各轮的旋转圈数相同。舱门打开时，驱动轮组件逆时针旋转，下轮绕绳圈数由3圈变化成5圈，带动缠绕轮组件下轮逆时针旋转，绕绳圈数由5圈变化成3圈，进而使缠绕轮组件上轮亦逆时针旋转，绕绳圈数由3圈变化成5圈，带动牵引点组件由右侧移动到左侧。舱门关闭时，驱动轮组件顺时针旋转，上轮绕绳圈数由3圈变化成5圈，带动牵引点组件由左侧移动到右侧，亦带动缠绕轮组件上轮顺时针旋转，绕绳圈数由5圈变化成3圈，从而使缠绕轮组件下轮绕绳圈数由3圈变化成5圈，驱动轮组件下轮绕绳圈数由5圈变化成3圈。
驱动轮组件和缠绕轮组件上所有轮槽半径相同，但由于其上绕绳圈数不同，故每层绳系驱动轮和缠绕轮的回转半径不一致，将导致一轮的收绳长度与另一轮的放绳长度不同，引起绳系中间芳纶绳长度的变化，绳系张紧力亦发生变化。上层绳系通过扭簧进行调节，下层绳系通过压簧调节。要求绳系机构运行中，绳系张紧力始终存在的同时保证绳系不松脱失效。因此，精确控制舱门开合运动中的绳系张紧力是一大难题。
为解决双层联动绳系机构的绳系张紧力精确控制的问题，本发明提供一种双层联动闭环绳系安装方法，实现双层联动绳系机构的安装，有效保证双层联动绳系机构的装调质量。

为了更清楚地说明本发明实施方式或现有技术中的技术方案，下面将
对实施方式中所需要使用的附图作简单地介绍。显而易见地，下面描述中的附图仅仅是本发明的一些实施方式，对于本领域普通技术人员而言，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
在针对本发明的实施方式进行描述时，术语“纵向”、“横向”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”所表达的方位或位置关系是基于相关附图所示的方位或位置关系，其仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此上述术语不能理解为对本发明的限制。
下面结合附图和具体实施方式对本发明作详细地描述，实施方式不能在此一一赘述，但本发明的实施方式并不因此限定于以下实施方式。
根据本发明的构思，针对双层联动闭环绳系机构中双层绳系安装的问题，本发明的安装方法对绕绳顺序、绕绳牵引的方向和绳长预留的设计，同时在安装的过程中对双层联动闭环绳系机构运行时由于收放绳差而产生的绳系张紧力进行考虑，实现双层绳系张紧力的精确控制，同时保证双层绳系不松脱失效。
如图1所示，本实施方式的双层联动闭环绳系安装方法的步骤包括：
首先，计算双层联动闭环绳系机构中驱动轮组件和缠绕轮组件的收放绳差。
双层联动闭环绳系机构的结构如图2所示。双层联动闭环绳系机构的缠绕轮组件的上轮绕绳的周数和驱动轮组件的下轮绕绳的周数相同，缠绕轮组件的下轮绕绳的周数和驱动轮组件的上轮绕绳的周数也相同，而且缠绕轮组件的上轮绕绳的周数小于驱动轮组件的上轮绕绳的周数，也就是驱动轮组件的下轮绕绳的周数小于缠绕轮组件的下轮绕绳的周数。以下层绳系为例，在双层联动闭环绳系机构安装的初始状态，驱动轮组件下轮的回转半径R1为驱动轮组件下轮的绳槽半径R与在驱动轮组件下轮上缠绕多周的绳系的直径h之和。缠绕轮组件下轮的回转半径R2为缠绕轮组件下轮的绳槽半径R与在缠绕轮组件下轮上缠绕多周的绳系的直径h之和。当驱动轮组件和缠绕轮组件的下轮同时转动
时，驱动轮组件的下轮收绳量与缠绕轮组件的下轮放绳量的差为收放绳差。收放绳差为：
如图2所示，缠绕轮组件和驱动轮组件的上轮绕绳的周数不同，下轮绕绳的周数也不同，导致上层绳系和下层绳系的张紧力都会发生变化。上层绳系的张紧力通过缠绕轮组件上轮设置的扭簧调节，下层绳系的张紧力通过导向轮组件下轮设置的压簧调节。上述导向轮组件可以设置为多个，在本实施方式中，导向轮组件设置两个，仅在图2中的导向轮组件2的下轮上设置一个压簧。压簧的结构以及设置方式如图4所示。由于上层绳系的张紧力和下层绳系的张紧力相同，而压簧的变形量便于测量，因此利用压簧的变形量来反映上下绳系张紧力的变化。
在双层联动闭环绳系机构开始运行时，当各轮转动一周前，回转半径不变，收绳量小于放绳量，收放绳差随各轮的回转角度增加而增大，且呈线性变化，压簧的变形量随之缩小而进行调节，控制绳系张紧力亦变小。当各轮转动一周时，收放绳差达到最大，绳系张紧力达到最小。当各轮转动第二周时，回转半径大小正与前述相反，收绳量大于放绳量，收放绳差随回转角度增加而增大，绳系张紧力亦随压簧调节而变大。
其次，根据上述收放绳差计算双层联动闭环绳系机构中导向轮组件的压簧的变形量。根据双层联动闭环绳系机构运行过程中产生的最大收放绳差
，计算绳系最大张紧力降至最小张紧力时压簧的变形量
为：
其中，
表示导向轮组件下轮两端绳之间的夹角。
设定压簧的最小受力F′,根据压簧的变形量及压簧的刚度计算压簧的最大受力为
，其中，K表示压簧的弹性系数。
然后，再根据上述压簧的变形量计算双层联动闭环绳系机构的绕绳缠绕力。根据压簧刚度曲线和压簧的最大变形量
，在压簧工作范围选择最小压簧力及最大压簧力，从而确定对应的压簧变形量。以最大压簧力F和最大压簧变形量
为绕绳控制依据，计算得到绕绳缠绕力为：
其中，
表示导向轮组件下轮（有压簧）两端绳之间的夹角。
接下来根据上述绕绳缠绕力对上层绳系和下层绳系进行安装。先在驱动轮组件的上层绳系施加上述绕绳缠绕力，对驱动轮组件和缠绕轮组件的上层绳系进行绕绳。具体过程是：
对驱动轮组件和缠绕轮组件的上轮分别单独绕绳，每轮使用一根绳，绕绳方法一致。上层绳系包括第一上层绳系和第二上层绳系。如图3所示，将第一上层绳系的一端（或称为固定端）沿设置在缠绕轮组件的上轮的绳槽并穿过绳槽底部且位于上轮的出绳方向的切点处的绳槽穿绳孔，打结后用压板将该一端固定在缠绕轮组件的上轮上。再使用内六角扳手插入缠绕轮组件上轮轮轴的六方孔内，沿缠绕轮组件的上轮出绳的反方向旋转缠绕轮组件的上轮，将第一上层绳系绕在缠绕轮组件的上轮上。绕绳后，使用多个楔块卡入绳槽固定第一上层绳系，如图8所示。进一步地，本实施方式的缠绕轮组件的上轮绕绳旋转3周。
如图3所示，将第二上层绳系的一端（或称为固定端）同样沿设置在驱动轮组件的上轮的绳槽并穿过绳槽底部且位于上轮的出绳方向的切点处的绳槽穿绳孔，打结后用压板将该一端固定在驱动轮组件的上轮上。如图2所示，另一端沿驱动轮组件的上轮的出绳方向绕过在驱动轮组件上设置的张紧摆杆，并水平通过定滑轮，牵引与绕绳缠绕力
相同重量的砝码。如图5所示，再使用内六角扳手插入驱动轮组件上轮轮轴的六方孔内，沿驱动轮组件的上轮出绳的反方向旋转驱动轮组件的上轮，同时标记张紧摆杆旋转角度的初始位置，将第二上层绳系绕在驱动轮组件的上轮上。绕绳后，使用多个楔块卡入绳槽固定第二上层绳系。进一步地，本实施方式的驱动轮组件的上轮绕绳旋转5周。
然后，在驱动轮组件和缠绕轮组件的下层绳系施加绕绳缠绕力，对下层绳系进行绕绳。具体过程是：
下层绳系使用一根绳。将下层绳系的一端（或称为固定端）使用与缠绕轮组件的上轮相同的绕绳方法缠绕在缠绕轮组件的下轮，使用多个楔块固定绕绳后的下层绳系，使用工艺螺钉固定缠绕轮组件的下轮并限制下轮转动。进一步地，本实施方式的缠绕轮组件的下轮绕绳旋转5周。
将下层绳系的另一端沿缠绕轮组件的下轮的出绳方向绕过导向轮组件的下轮，沿着设置在驱动轮组件的下轮的绳槽穿过绳槽底部且位于下轮的出绳方向的切点处的绳槽穿绳孔，预留第一绳长K1后剪断打结，并使用工艺螺钉固定驱动轮组件的下轮并限制其转动，再将打结后的该另一端（或称为固定端）用压板固定在驱动轮组件的下轮上。其中，预留第一绳长K1的起点从绳槽穿绳孔算起，具体的计算方式为：
其中，R表示缠绕轮组件的上、下轮和驱动轮组件的上、下轮的半径，h表示第一上层绳系、第二上层绳系和下层绳系的绳的直径。
拆除所有的工艺螺钉，将缠绕轮组件和驱动轮组件的下轮的固定拆除，在下层绳系的中间拴上工艺绳沿出绳方向通过定滑轮，并牵引与绕绳缠绕力
相同重量的砝码，再使用内六角扳手插入驱动轮组件下轮轮轴的六方孔内，沿驱动轮组件的下轮出绳的反方向旋转驱动轮组件的下轮，直至压簧最大变形量为
L。进一步地，本实施方式的驱动轮组件的下轮绕绳旋转3周。
最后，对驱动轮组件和缠绕轮组件的上层绳系进行闭绳。
如图2所示，将第一上层绳系的另一端绕过导向轮组件的上轮，在牵引点组件安装的位置上使用牵引工装两端的夹片（如图9所示）对第一上层绳系的另一端和第二上层绳系的另一端施力，使张紧摆杆恢复至标记的初始位置。
将第一上层绳系和第二上层绳系的另一端分别沿着牵引点组件的两个缠绕座绳槽底部的穿绳孔，预留第二绳长K2（预留绳长起点从穿绳孔边缘算起）后剪断打结。如图7所示，再将打结后的第一上层绳系和第二上层绳系的另一端分别固定在牵引点组件的第一缠绕座（如图6所示的绳缠绕座1）和第二缠绕座（如图6所示的绳缠绕座2），再分别沿第一缠绕座和第二缠绕座的出绳的反方向旋转第一缠绕座和第二缠绕座相同周数并合并到一起，使用盖板和连接板固定牵引点组件。实现了绳系安装不并排、不交叠。
进一步地，本实施方式的第一缠绕座和第二缠绕座均绕绳旋转3周，且预留第二绳长K2为：
其中，R'表示第一缠绕座和第二缠绕座的半径，h表示第一上层绳系和第二上层绳系的绳的直径。
通过上述双层联动闭环绳系机构的安装方法，解决了电动舱门绳系机构的装调问题，实现了绳系安装不并排、不交叠。同时，通过绕绳过程的缠绕力值来精确控制机构运行时的绳系张紧力，解决了绕绳后无法调整绳系张紧力的问题。
以上所述仅为本发明的一个实施方式而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包括在本发明的保护范围之内。
