[0017] 总的说来， 本实用新型具有如下优点： 结构简单， 造价低廉， 通用性强， 便于 推广， 提高了生产力， 可作为液压和气动缸替代品使用。
[0018] 1.利用起重滑轮组的原理增大输出的直线驱动力， 可提供较大的直线驱动力。
[0019] 2.采用两个定滑轮模块配合一个动滑轮模块的结构， 可在动滑轮模块的左右两 侧形成两个相反方向的拉力， 实现动滑轮模块的往复运动。
[0020] 3.外壳主体以连接导柱连接使得整体结构更为牢固， 同吋连接导柱和导向块对 动滑轮模块的直线运动起引导作用， 使其始终在一条直线上运动。
[0021] 4.缸盖上可设置外壳安装槽， 方便外壳与缸盖的定位连接。
[0022] 5.缸盖上设置的推拉连接杆导孔对穿过的推拉连接杆起导向作用。
[0023] 6.减速卷扬机的减速部分还可以起到增力的作用。 同步双卷筒减速卷扬机是现 有的设备， 同轴双卷筒的采用， 在一个卷筒收索的同吋另一个卷筒在放索， 使 得动滑轮模块朝收索一方运动的同吋， 放索的一方为动滑轮模块下一步反方向 运动作好准备， 也更方便对动滑轮模块进行定位。
[0024] 7.将复杂的滑轮组系统收纳在外壳内和整体集约模块化的设计,不光外观简洁、 方便运输， 在机械装配和维修中更为方便， 同吋也使机械的整体结构设计更为 简单。
[0025] 8.以多种动力为驱动源的设计， 使其不光可与现有的液压和气动系统混合使用
， 特殊情况下还可以配以绞盘以人手驱动， 可塑性强、 适用范围广。
[0026] 9.作为液压气动缸的替代品， 由于其造价低廉使得设备整体价格下调， 降低了 生产成本， 利于设备的市场销售。
[0027] 10.在某些空间狭小设备 (如小型行走机械或便携式工具)中， 无法采用液压和气 动源， 但又必须要用到较大的直线驱动力吋， 由于本品可用电机或人手驱动， 正好可填补此空白。

实施该发明的最佳实施例 本发明的最佳实施方式
[0040] 下面将结合附图和具体实施方式来对本实用新型做进一步详细的说明。
[0041] 实施例一
[0042] 一种采用滑轮组的直线运动增力模块， 包括： 机架、 驱动马达、 卷扬机、 定滑 轮模块、 动滑轮模块、 牵引索、 直线导向机构、 直线执行元件。 各部件集约成 一整体， 可作为单独的提供较大直线驱动力的驱动机构使用， 通用性强。 整体 可通过一个法兰固定在外界机械上。
[0043] 机架包括： 两个缸盖和一个外壳， 缸盖位于最左端和最右端， 横截面为矩形的 外壳位于两者之间将将定滑轮模块、 动滑轮模块、 直线导向机构容纳在内， 将 复杂的滑轮组系统隐在内部。 两个缸盖的结构相同， 左右对称设置， 缸盖上设 有定滑轮模块安装腔 （用于定滑轮模块的端部嵌入安装） 、 外壳安装槽 （用于 外壳的端部嵌入） 、 连接导柱固定螺丝孔、 定滑轮模块固定螺丝孔。 缸盖设有 供牵引索引出的引出口。
[0044] 定滑轮模块和动滑轮模块均为箱体结构， 箱体表面设有多个凹进去的安装腔， 定滑轮或动滑轮安装在安装腔内， 一个定滑轮或动滑轮对应一个安装腔； 定滑 轮模块的数量为两个， 分别安装在左端和右端缸盖上， 每个定滑轮模块面对动 滑轮模块的一侧均设有多个定滑轮； 动滑轮模块的数量为一个， 左右两侧均设 有多个动滑轮， 位于左侧的动滑轮与左侧定滑轮模块的定滑轮构成一组起重滑 轮组， 位于右侧的动滑轮与右侧定滑轮模块的定滑轮构成另一组起重滑轮组。 定滑轮模块设有供牵弓 I索引出的引出口， 当定滑轮模块嵌入缸盖吋， 定滑轮模 块的引出口与缸盖的引出口正对。 本实施例中的起重滑轮组设计为定滑轮和动 滑轮一一隔幵的结构， 即： 牵引索依次通过动滑轮、 定滑轮、 动滑轮、 定滑轮 、 动滑轮 ......， 最终固定在定滑轮模块上。
[0045] 直线导向机构包括四根相互平行的连接导柱、 四个导向块。 连接导柱的两端分 别固定在左右两端缸盖相应的连接导柱固定螺丝孔中。 导向块固定并嵌入在动 滑轮模块中， 并套在对应的连接导柱中。 通过直线导向机构实现动滑轮模块相 对于定滑轮模块的直线平移， 远离或靠近定滑轮模块。 由于直线导向机构起左 右两端缸盖的连接作用， 此吋外壳无需起连接作用。 [0046] 直线执行元件为一个连接块； 连接块固定在动滑轮模块的上侧； 外壳上设有从 左端缸盖延伸至右端缸盖的、 供连接块穿过至外界且允许连接块直线平移的幵 槽。 连接块平移吋， 可产生横切力式的直线驱动力。
[0047] 牵引索的数量为两条， 左右对称设置。 位于左侧的牵引索的一端与卷扬机相接 ， 另一端固定在左侧定滑轮模块上， 中间绕过左侧起重滑轮组。 位于右侧的牵 引索的一端与卷扬机相接， 另一端固定在右侧定滑轮模块上， 中间绕过右侧起 重滑轮组。
[0048] 卷扬机为同步双卷筒减速卷扬机， 当其中一条牵引索被收索吋， 另一条牵引索 被放索， 即左侧牵引索收索， 右侧牵引索放索； 左侧牵引索放索， 右侧牵引索 收索。
[0049] 驱动马达驱动卷扬机运行， 它和卷扬机均安装在外壳的外侧。
[0050] 使用吋， 驱动马达启动， 卷扬机运行， 左侧牵引索放索， 右侧牵引索收索， 动 滑轮模块通过直线导向机构向右侧平移， 带动直线执行元件向右侧平移， 此吋 直线执行元件 （连接块） 即可产生向右的直线驱动力作用于与其相接的机械构 件。 改变驱动马达的转向， 即可产生向左的直线驱动力作用于与其相接的机械 构件。
[0051] 由于有多段牵引索与动滑轮模块相接， 动滑轮模块所受牵引索的合力为单段牵 引索拉力的多倍， 因此产生的直线驱动力被有效增大。 设置两组起重滑轮组， 动滑轮模块可在直线方向上定位于任意位置且可方便的复位。

[0053] 本实施例中， 直线导向机构同实施例一。

[0060] 本实施例未提及部分同实施例一。
[0061] 实施例四
[0062] 本实施例中， 直线导向机构同实施例一。
[0063] 直线执行元件为一根推拉连接杆， 推拉连接杆的长度方向与动滑轮模块的直线 运动方向一致。 推拉连接杆的一端固定在动滑轮模块的右侧， 另一端穿过右侧 的缸盖上设置的推拉连接杆导孔并伸出。
