所述的推动器 1包括驱动装置 2和由该驱动装置驱动的液体泵 3及蓄液箱 4、 液 压缸 5, 液体泵 3的进口与蓄液箱 4相通， 液体泵 3的出口与液压缸的驱动液腔 6相 通， 液压缸的非驱动液腔 21与蓄液箱 4相通， 液压缸的活塞杆即推杆 7与驱动臂 8铰 轴式连接， 并通过驱动臂 8作用于制动部分 9中的制动臂 10， 所述的蓄液箱 4内有空 气腔， 以消除蓄液箱内的真空状态， 利于推动器工作过程中液体介质的流动。
所述的叠加制动机构为叠加制动机构 11a;
所述的叠加制动机构 11a, 包括叠加制动构件 12、 推力杆 13和套筒 18， 推力杆 13的内段及叠加制动构件 12位于套筒 18内， 推力杆 13的外端与推力臂 15铰轴式连 接， 即推力杆 13通过其外端与推力臂 15的铰轴式连接而作用于制动部分 9中的制动 臂 10; 叠加制动机构 11a还包括使叠加制动构件 12存储和释放能量的电磁装置 14, 电磁装置 14包括电磁线圈和吸块 17， 电磁装置 14的电磁线圈与套筒 18连接， 叠加 制动构件 12为弹簧构件， 推力杆 13的内段穿经弹簧式叠加制动构件 12和电磁装置 14， 推力杆 13的内段上有一可沿该推力杆滑动的滑块 23， 弹簧式叠加制动构件 12位 于套筒 18的端盖 24与滑块 23之间， 其两端分别作用于套筒 18和滑块 23， 推力杆 13 的内端部设有用于吸块 17的限位块 19，电磁装置的吸块 17位于电磁线圈与限位块 19 之间并与电磁线圈配合使用， 限位块 19与推力杆 13为螺纹连接， 通过调节限位块 19 于推力杆 13上的相对位置， 可调节弹簧式叠加制动构件 12的作用力参数， 吸块 17上 延伸一管套 20， 弹簧式叠加制动构件 12通过滑块 23与管套 20作用于吸块 17。
在实施本发明时， 与推杆 7铰轴式连接的驱动臂 8， 以及与推力杆 13铰轴式连接 的推力臂 15可为多种形式， 如图 1至图 3所示， 推力臂 15与驱动臂 8重叠， 即驱动 臂 8的下段为推力臂 15。
图 1至图 3所示的结构中， 推动器 1的右端即连接端及叠加制动机构 1 1a中的套 筒 18的右端即连接端与制动部分中的另一制动臂 10的延长臂 22铰轴式连接，使得两 制动臂 10可同时向外张开或向内縮进，即所述推动器 1及叠加制动机构 11a中的套筒 18有与制动部分中另一制动臂 10的延长臂 22连接的连接端， 该种连接结构即立式结 构。
由于所述叠加制动机构中设有电磁装置 14， 且利用切断电源来实现叠加制动的控 制， 因此， 在应用设有叠加制动机构的多台制动器对同一被制动物体进行制动时， 有 利于叠加制动时的同步。
图示的制动部分为瓦块式结构， 本发明也可用于盘式结构的常闭制动器。
图 1所示的叠加制动装置的工作过程是， 驱动装置 2工作带动液体泵 3运转， 压 力液体进入液压缸 5的驱动液体腔 6内， 活塞杆即推杆 7伸出至所设定的位置 （如图 2所示）， 通过驱动臂 8作用于制动部分 9中的制动臂 10， 叠加制动机构 11a的推力杆 13随之伸出， 吸块 17与电磁线圈接触， 即克服制动部分中的制动机构 16的制动力和 叠加制动机构 11a的叠加制动力， 两制动臂 10向外张开， 并保持定位， 即制动器的常 闭制动和叠加制动均被解除， 此时被制动物体则处于运转状态； 当需要制动时， 切断 驱动装置电源， 液体泵 3停止运转， 液压缸驱动液体腔 6内的液体即处非压力状态， 此时， 因制动器常闭制动机构 16的制动力作用， 推杆 7即缩进而复位（如图 3所示）， 制动臂 10向内缩进， 推力杆 13随之产生第一次缩进， 液压缸驱动液体腔内的液体同 时经由液体泵向蓄液箱 4回流， 制动器即复位于常闭制动， 打幵和恢复常闭制动的工 作过程可单独应用于制动频繁的工况； 在制动器复位于常闭制动后， 因电磁装置 14通 电， 吸块 17处吸合状态， 通过其伸出的管套 20及滑块 23作用于弹簧式叠加制动构件 12, 使弹簧式叠加制动构件 12保持蓄能状态； 根据需要， 需实施叠加制动时， 切断电 磁装置 14的电源， 弹簧式叠加制动构件 12释放能量， 使滑块 23及吸块 17沿推力杆 13右移， 吸块 17即与推力杆 13端部的限位块 19接触并被限位， 见图 1所示， 在吸 块 17沿推力杆 13右移至与限位块 19接触时， 叠加制动构件 12释放的能量继而作用 于限位块 19, 使限位块 19产生右移 （图示方向）， 限位块 19即拉动推力杆 13向套筒 18内再次缩进， 推力杆 13则拉动推力臂 15， 推力臂 15即作用于制动臂 10， 使得制 动臂 10产生向内缩进或产生向内缩进的趋势， 从而对被制动物体实现叠加制动， 即常 闭制动和叠加制动均处制动状态。 使常闭制动和叠加制动均处制动状态的操作过程， 可使用于需要更稳固可靠时的制动， 如被制动物体处于不需要频繁制动或处于歇工、 停工等状态时的制动， 以增加被制动物体在静态情况下的制动稳定性。
图 4为以图 1为基础增设一级叠加制动机构 11a, 即设有两级叠加制动机构 l la， 增设一级叠加制动机构 11a的结构同前述， 即可对被制动物体进行两次叠加制动。

所述的叠加制动机构为叠加制动机构 l lb， 叠加制动机构 l ib包括叠加制动构件 12、 推力杆 13和套筒 18， 推力杆 13的内段及叠加制动构件 12位于套筒 18内， 叠加 制动构件 12为弹簧构件， 推力杆 13的内段穿经弹簧式叠加制动构件 12， 推力杆 13 的内段上连接块件 28，弹簧式叠加制动构件 12位于套筒 18的端盖 24与块件 28之间， 其两端分别作用于套筒 18和块件 28， 块件 28与推力杆 13为螺纹连接， 通过调节块 件 28于推力杆 13上的相对位置， 可调节弹簧式叠加制动构件 12的作用力参数； 推力 杆 13通过其外端与推力臂 15的铰轴式连接而作用于制动部分 9中的制动臂 10， 推力 臂 15的另一端与套管 25的外端接触， 并作用于套管 25, 如图所示， 推力臂 15与套 管 25外端接触的端部上设有滚轮 29, 即推力臂 15通过其端部的滚轮 29与套管 25的 外端接触， 以减少推力臂 15的该端部与套管 25接触状态下相对位移的摩擦力；
叠加制动机构 l ib还包括使叠加制动构件 12存储和释放能量的电磁装置 14， 所 述的电磁装置 14设在推动器 1内， 电磁装置 14包括电磁线圈和吸块 17， 电磁线圈与 蓄液箱 4的箱壁连接， 或通过构件 27与液压缸 5的缸壁连接， 吸块 17位于电磁线圈 与活塞环 26之间与电磁线圈配合使用， 并连接于套管 25上， 可随套管 25移动。

该实施结构包括推动器 1， 所述推动器包括驱动装置 2和由该驱动装置驱动的液 体泵 3及蓄液箱 4、 液压缸 5， 液体泵 3的进口与蓄液箱 4相通， 液体泵 3的出口与液 压缸的驱动液腔 6相通， 液压缸的非驱动液腔 21与蓄液箱 4相通， 液 ££缸的活塞杆即 推杆 7与驱动臂 8铰轴式连接， 并通过驱动臂 8作用于制动部分 9中的制动臂 10， 设 有可使制动部分实现叠加制动的叠加制动机构；
所述推动器 1的推杆 7上设有套管 25, 套管 25的外端位于蓄液箱 4外部， 套管 25的内段位于液压缸 5的非驱动液体腔 21内， 推杆 7向外伸出时可带动套管 25向外 伸出， 在推杆 7向内缩进时， 推杆 7与套管 25可产生相对滑动； 所述的叠加制动机构为杠杆式叠加制动机构 l lc， 杠杆式叠加制动机构 11c包括 驱动杠杆 30、 拉杆 31 , 驱动杠杆 30和拉杆 31分别为对称设置的两根， 驱动杠杆 30 的一端与制动部分 9的制动臂 10连接， 驱动杠杆 30的另一端设置叠加制动构件即重 块 32, 两拉杆 31的下端分别与两驱动杠杆 30中部铰轴式连接， 两拉杆 31的上端分 别连接于连接杆 33的两端 （见图 11 )， 连接杆 33的中部与套管 25的上端接触； 杠杆式叠加制动机构 11c还包括使叠加制动构件即重块 30存储和释放能量的电 磁装置 14， 电磁装置 14设在推动器 1内 （参见图 8所示）， 电磁装置 14包括电磁线 圈和吸块 17， 电磁线圈通过构件 27与液压缸 5的缸壁连接， 或通过其他构件与蓄液 箱 4的箱壁连接， 吸块 17位于电磁线圈与活塞环 26之间与电磁线圈配合使用， 并连 接于套管 25的内端上， 可随套管 25移动。

杠杆式叠加制动机构 11c的工作过程是， 驱动装置 2工作带动液体泵 3运转， 压 力液体进入液压缸 5的驱动液体腔 6内， 活塞杆即推杆 7伸出至所设定的位置， 并带 动套管 25向外伸出.， 使连接杆 33向上位移， 连接杆 33即带动拉杆 31向上位移， 拉 杆 31随之带动驱动杠杆 30绕铰接轴 34逆时针上摆， 重块 32被提升而处蓄能状态， 同时使得制动部分的两制动臂 10向外张开，即制动部分的常闭制动和杠杆式叠加制动 机构的制动被解除， 被制动物体处运转状态； 制动时， 首先是切断驱动装置的电源， 液体泵 4停止运转， 推杆 8下落至所设定位置， 制动部分恢复常闭制动， 被制动物体 即停止运转； 此时， 因电磁装置 14通电， 吸块 17仍被电磁线圈的电磁力吸住， 使得 套管 25仍处伸出状态， 而使被提升的重块 30保持蓄能状态； 当切断电磁装置的电源 时， 电磁吸力被解除， 重块 32因重力作用而下落， 一是使套管 25带动吸块 17下落， 二是通过驱动杠杆 30使得制动部分的两个制动臂 10向内缩进或产生向内缩进的趋势， 从而对被制动物体实现叠加制动， 使被制动物体的制动状态更加稳定和可靠。

图 12所示叠加制动机构 11a的工作过程是， 驱动装置 2工作带动液体泵 3运转， 压力液体进入液压缸 5的驱动液体腔 6内， 活塞杆即推杆 7伸出至所设定的位置， 通 过驱动臂 8作用于制动部分 9中的制动臂 10, 叠加制动机构 11a的推力杆 13随之伸 出， 吸块 17随之与电磁线圈接触， 即克服制动部分中的制动机构 16的制动力和叠加 制动机构 11a的叠加制动力， 两制动臂 10向外张开， 并保持定位， 即制动器的常闭制 动和叠加制动均被解除， 此时被制动物体则处于运转状态； 当需要制动时， 切断驱动 装置电源， 液体泵 3停止运转， 液压缸驱动液体腔 6内的液体即处非压力状态， 此时， 因制动器常闭制动机构 16的制动力作用， 推力杆 13随之产生第一次缩进， 由于驱动 臂 8的作用， 推杆 7即缩进而复位， 制动臂 10向内缩进， 液压缸驱动液体 内的液体 同时经由液体泵向蓄液箱 4回流， 制动器即复位于常闭制动； 在制动器复位于常闭制 动后， 因电磁装置 14通电， 吸块 17仍处吸合状态， 通过其伸出的管套 20及滑块 23 作用于弹簧式叠加制动构件 12， 使弹簧式叠加制动构件 12保持蓄能状态； 需实施叠 加制动时， 切断电磁装置 14的电源， 弹簧式叠加制动构件 12释放能量， 使滑块 23及 吸块 17沿推力杆 13下移， 吸块 17即与推力杆 13端部的限位块 19接触并被限位， 在 吸块 17沿推力杆 13下移至与限位块 19接触后， 叠加制动构件 12释放的能量继而作 用于限位块 19， 使限位块 19产生下移， 限位块 19即拉动推力杆 13向套筒 18內再次 缩进， 推力杆 13则向下拉动驱动臂 8， 驱动臂 8即再次作用于制动臂 10， 使得制动臂 10产生向内缩进或产生向内缩进的趋势， 从而对被制动物体实现叠加制动。
