具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明的保护范围。
图1所示为张力均衡装置的一个实施例，由两个基本安装模块通过套筒2-4连接组成，参见图3，每个基本安装模块包括两个滚筒储绳装置1、两个设置在滚筒储绳装置1内部的行星架2-2和四个安装在滚筒储绳装置1两侧的锥齿轮传动机构2；基本安装模块固定在传力架3的传力轴3-1上，传力轴3-1在安装轴承部分设有阶梯，阶梯上开设沟槽，用以安装弹性挡圈以固定轴承，安装轴承部分阶梯精加工；行星架2-2由端盖固定在滚筒中部；进一步地，两个滚筒储绳装置1之间和滚筒储绳装置1与传力架3的侧纵梁3-2、中纵梁3-3之间可以设置防尘罩。图4为图3中A-A的剖视图，示出了张力均衡装置在滚筒储绳装置1中部的断面图，可见，锥齿轮传动机构2包括轴交角为90度的啮合锥齿轮组，该实施例啮合锥齿轮组包括多个小锥齿轮2-1和位于其两侧的两个大锥齿轮2-3，小锥齿轮2-1固定在行星架2-2的分支2-2-1上，可绕轴旋转，但不可轴向移动；行星架2-2插在滚筒储绳装置1的行星架凹槽1-1-1中，由分支2-2-1两端平面进行定位；两端大锥齿轮2-3上加工有键槽，用通过键连接套筒2-4，两个滚筒储绳装置1位于中间的大锥齿轮2-3背靠背通过高强度螺栓连接，行星架2-2和大锥齿轮2-3可绕轴自由旋转；大锥齿轮2-3中部开设有凹槽安装弹性挡圈用以固定轴承，由于此大锥齿轮2-3不承受径向载荷，因此大锥齿轮2-3中部减薄，仅保留少量轮辐。
图5为图1实施例的传力架3，所述的传力架3主要由一个传力轴3-1、两个侧纵梁3-2、一个中纵梁3-3、六个横梁、若干角钢3-4和四个立柱3-5组成，侧纵梁3-2、中纵梁3-3、横梁和立柱3-5之间通过角钢3-4连接形成两个大小均等的容纳空间的结构框体，容纳空间的数量是与基本安装模块 的数量匹配一致的，传力轴3-1横向设置于结构框体的中部，传力轴3-1穿过中纵梁及其两侧的容纳空间，最终两端通过轴承安装于侧纵梁3-2上，相邻两个基本安装模块的传力轴3-1通过轴承安装在同一套筒2-4内；载荷经传力轴3-1传至侧纵梁3-2和中纵梁3-3上，纵梁又经角钢3-4通过螺栓连接将载荷传递至立柱3-5上，立柱3-5直接与提升容器相连，将载荷传递至提升容器受力部位(如箕斗、轿厢)。
图7所示为实施例中的行星架2-2，所述的行星架2-2具有四个个周向均布的分支2-2-1，每个分支2-2-1安装锥齿轮处为阶梯轴，分支2-2-1的末端设有螺纹孔2-2-2，用以与滚筒储绳装置1的端盖固定连接，每个分支2-2-1上通过轴承安装一个锥齿轮传动机构2的小锥齿轮2-1，行星架2-2可根据实际情况，改变行星架2-2的分支2-2-1个数，增加或减少小锥齿轮2-1个数。分支2-2-1的末端行星架2-2的内侧通过轴承安装在传力轴3-1上，行星架2-2的外侧安装于滚筒储绳装置1的行星架凹槽1-1-1内。所述的行星架2-2的内侧开设有安装弹性挡圈的凹槽，进而固定轴承。所述分支2-2-1与行星架凹槽1-1-1配合处两端面磨平，增加接触面积。
图8a和8b所示实施例中的滚筒储绳装置1，它包括滚筒轮体1-1，滚筒轮体1-1的轮缘部分布置有螺旋形状的绳槽1-1-2，每个基本安装模块的两个滚筒储绳装置1上钢丝绳4的绕绳方向相反，钢丝绳4一端浇铸有绳头4-1，通过图9所示缠绕方式缠绕在绳槽1-1-2处，钢丝绳4的绳头4-1穿过轮辐上的通孔1-1-5固定在轮缘外侧；滚筒轮体1-1的内侧设有行星架凹槽1-1-1，滚筒轮体1-1的轮毂上安装有端盖。优选地，所述滚筒轮体1-1的轮辐边缘设置有加强筋1-1-3，加强筋1-1-3中间开设有减轻孔1-1-4， 以减轻整体重量；具体地，滚筒轮体1-1的轮毂上钻有用于安装端盖的螺钉孔，以固定行星架2-2。
实施例中所述轴承为滚针轴承，内外圈允许一定分离,外圈由孔用弹性挡圈固定，内圈由轴用弹性挡圈固定。
图1实施例为多自由度系统，其大距离调绳的钢丝绳张力自动均衡的原理如下：
当提升过程中钢丝绳张力存在不均衡现象时，滚筒储绳装置1通过旋转使钢丝绳4的长度增加或减少，进而改变钢丝绳4上的张力，当调整结束后，滚筒储绳装置1不再旋转；此时，钢丝绳4作用在滚筒轮体1-1上的转矩由行星架2-2两端大锥齿轮2-3平衡；大锥齿轮2-3公用一个小锤齿轮2-1。由于小锥齿轮2-1静止，转矩平衡，行星架2-2两端的大锥齿轮2-3提供转矩相同；滚筒储绳装置1之间的大锥齿轮2-3背靠背通过螺栓连接，或者通过套筒2-4加键的方式连接，两大锥齿轮2-3受力平衡，受到转矩大小相同方向相反。因此相邻滚筒轮体1-1承受转矩大小相同；进一步由于绳槽1-1-2直径相同，所以相邻滚筒轮体1-1上钢丝绳张力相同；故图1中四条钢丝绳4张力全部相同。
上述实施例以两个基本模块，四根钢丝绳4为例，实际使用过程中可根据实际需求增加或减少安装模块。图2所示为安装三个基本安装模块的张力自动均衡装置，其工作原理与图1实施例相同。图6所示为安装三个基本安装模块的张力自动均衡装置实施例的传力架3的结构图，与图5所示的图1实施例的传力架3的结构区别在于增加了一个容纳空间。
以上所述，仅是本发明的较佳实施例，并非对本发明做任何形式上的限 制，凡是依据本发明的技术实质，对以上实施例所做出任何简单修改和同等变化，均落入本发明的保护范围之内。
