具体实施方式
下面结合附图对本发明优选实施例作详细说明。
如图1-11所示，本实施例包括电机丝杆推块复位机构、电磁铁复位机构、摩擦动/定制动衬板机构、电磁触发机构等，其连接关系为：电机丝杆推块复位机构安装在上顶板与锁钩架之间，电磁铁复位机构与电机丝杆推块复位机构相连，摩擦制动动/定制动衬板安装在动/定制动板上，电磁触发机构安装在后侧板上，具体结构如下所述：
顶板41安装于钢丝绳制动器的上部，两块侧板26分别安装于钢丝绳制动器两侧的安装板16上，安装板16通过底部安装孔固定安装于横梁上，后侧板13安装于钢丝绳制动器的后侧面(与钢 丝绳相对的一侧)，组成了钢丝绳制动器的框架。
安装座包括安装板16、调整螺钉15、固定销14等，安装板16垂直安装于电梯轿厢的横梁后，通过其侧面支点螺钉161连接于侧板26的偏转轴孔266内，使侧板26可以绕其转动，侧板26转动0-45度角度后，通过调整螺钉15连接于侧板26的偏转锁螺纹孔264实现锁紧，再用电钻通过销孔在侧板26上打孔后装入固定销14或将安装板16与侧板26焊接，防止制动过程中侧板26绕支点螺钉161偏转。上述连接结构，通过侧板26安装角度的调整来实现制动板与钢丝之间角度调整，调整到位后，再将侧板26固定。
电机丝杆推块复位机构包括销轴7、支杆8、拉簧9、弹簧导向座10、支座11、蓄能弹簧17、滑动轴18、弹簧座19、导轨27、滑块28、锁钩29、锁钩架30、推块33、丝母34、丝杆36、电机37、连轴套38、电机安装板39、减速机40等，顶板41之上安装电机安装板39，减速机40安装于电机安装板39上，减速机40由电机37驱动而运行，电机37的外壳体固定于电机安装板39。减速机40的传动轴与丝杆36的上端通过连轴套38相连而连动，丝杆36的另一端形成外螺纹并旋接丝母34，且丝杆36的该端活动式地穿过推块33后，转动式地定位于锁钩架30。丝母34固定安装于推块33的上表面，丝杆36在电机37的驱动下而转动，随之通过外螺纹推动丝母34运动，进而使推块33一起运动。
推块33固定连接滑块28，导轨27纵向穿过滑块28，两者间滑动式配合。导轨27安装于后侧板13，形成导向和承载。在丝母34运动的同时，带动滑块28在导轨27上作运动。
推块33的底端形成斜面，该斜面正对滑动轴18，滑动轴18横向穿过两个弹簧座19，且其两端分别滑动式地置入两侧板形成的开口圆弧槽262。
蓄能机构包括弹簧17、两个弹簧座191、弹簧支撑轴192，左右侧板26之间安装有弹簧支撑轴192，弹簧支撑轴192的两端分别安装于两侧板的弹簧座轴孔265内，两弹簧座191安装于弹簧支撑轴192，两弹簧座191与上部的两弹簧座19上下相对应，上下相对应的弹簧座19、191间各装入一蓄能弹簧17。
定制动板24安装于左右两侧板26上，连接结构：两侧板26上各具有一销263，与此相对应的，定制动板24上形成销孔，首先通过销263与定制动板24的销孔定位；再通过定板连接孔261连接：两侧板26的前侧边沿处各形成数个定板连接孔261，两侧板26的前侧边沿贴合定制动板24，两者间通过螺钉连接即螺钉穿过定制动板24后旋入定板连接孔261。定制动板24的内侧面固定安装锁钩架30，锁钩架30通过销轴转动式地装配锁钩29，锁钩29形成与滑动轴18外壁相对应的钩槽296，其能钩住滑动轴18且也能释放。锁钩29的另一端(外端)活动式地伸出后侧板13，且该端之上正对冲击杆3的下端。
当电机37通电后开始运转，通过减速机40的输出轴传动到丝杆36，进而使丝母34在丝杆36上运动，带动推块33运动，通过推块33的斜面压向滑动轴18，滑动轴18通过弹簧座19实现对蓄能弹簧17的压缩，压缩蓄能弹簧到位后，锁钩锁住滑动轴，电机反转退回初始状态，从而实现钢丝绳制动器的自动复位。
销轴7、支杆8、拉簧9、弹簧导向座10、支座11等装配结构参见下文。
电磁铁复位机构包括销轴7、支杆8、拉簧9、弹簧导向座10、支座11，一对支座11安装于后侧板13，每一支座11上安装一根能上下转动的支杆8，支杆8的另一端(外端)形成销孔，销轴7横穿两支杆8的销孔，处于其中一根支杆8之外的销轴7的一端连接拉簧9的一端，拉簧9的另一端连接于锁钩29的外端，以实现锁钩29的复位。处于两支杆8之间的一段销轴7连接弹簧导向座10，弹簧导向座10与冲击杆3的下端相连，冲击杆3局部外套压缩弹簧。后侧板13形成两个穿孔，每个穿孔用于上下活动式地穿过一根支杆8的内端，支杆8的内端向上凸并正对滑块28的下表面。当滑块28向下运动时，其下表面顶触支杆8的内端，使支杆8摆动，从而通过支杆8的作用，连动弹簧导向座10，进而带动冲击杆3向上运动，压缩电磁铁冲击杆上的弹簧，当弹簧压缩后，外电源给电磁铁供电，通过电磁力保持弹簧力，以实现失电电磁铁的自动复位。
电机转动过程中，通过与丝母相连的推块运动到设定位置后与支杆内端相接触，当推块运动到设定位置时，推动支杆转动，支杆带动弹簧导向座运动，通过冲击杆上安装的弹簧导向座带动冲击杆运动，实现对电磁铁内冲击杆上的弹簧压缩，弹簧压缩到位后，拉簧拉动锁钩的外端，直至锁住滑动轴，此时电机反转，支杆失去顶压力而恢复初态，实现失电电磁铁的自动复位。
摩擦动/定制动衬板机构包括导向轴23、定制动板24、动制动板22、制动衬35，定制动板24与动制动板22纵向平行布设，两者的相对面都装有制动衬35，且与制动衬35的装配结构是相同的，下面对动制动板22与制动衬35的装配结构予以详述：动制动板22(朝定制动板24)的一侧面形成两个长方体形的凹部，两凹部分别延伸至动制动板22的上下边沿，该凹部的两侧边沿为制动板台面221，且于两凹部的同侧各开有制动衬调整孔20(本实施例选用长条形孔，以使其能旋接多颗螺钉)；与此相对应的，制动衬35形成凹部，该凹部的边沿为与制动板台面221相适配的制动衬台面351，制动衬35嵌入动制动板22的两凹部之间部分且两者的台面相触，两侧台面221的宽度与制动衬35的宽度相适配，通过螺钉拧紧于制动衬调整孔20而将两者固定。制动衬35的制动面形成与钢丝绳外形相适配的纵向弧形凹槽，且其突出于动制动板22的该侧面。两制动板22、24上的制动衬35形成与钢丝绳根数相对应的纵向弧形凹槽，相对应的纵向弧形凹槽间穿过钢丝绳25，常态下，与钢丝绳25间留有间隙。
上述涉及一块制动衬的情况，其中，弧形凹槽数量可以根据需要组合使用，以满足不同钢丝数量的要求。作为本发明的优选技术方案，制动衬选用多块组合，如图7a、7b、7c、7d、7e所示，第一块制动衬有2道圆弧槽，第二块制动衬有3道圆弧槽，两者组合后形成5道圆弧槽，与5条钢丝相适配。制动衬通过台阶面相互配合固定，能在制动板不更换的情况下，通过制动衬组合以适应不同钢丝绳根数。
动制动板22的外侧面通过固定螺钉312安装两固轴板31，固轴板31与动制动板22间垫入调整垫片314。两固轴板31间穿过连臂轴32，并通过固定销311固定，以防其转动。动制动板22上还安装有两根支撑销313，支撑销313朝向动制动板22的外侧，处于连臂轴32的下方，从而通过支撑销313的支撑作用，以防止连臂轴32制动过程中向下滑动。在固轴板31与动制动板22之间安装调整垫片314，用于调整滑动轴18的高低，通过滑动轴18的高低来实现不同放大比及弹簧力，以满足不同制动系统质量要求。
导向轴23连接定制动板24与动制动板2。动制动板22的四角各开有一个孔222，与此相对应的，定制动板24的四角也各开有一个孔，两者相对应的孔间连接一导向轴23，导向轴23与动制动板22相固定连接，而与定制动板24间滑动式配合，或者反之即导向轴23与动制动板22滑动式配合，而与定制动板24固定连接。
动制动板22的外侧面固定连接固轴板31，固轴板31装配有连臂轴32，连臂轴32的两端伸出固轴板31之外，且端部各转动配合一连臂21的一端。连臂21的另一端转动配合于滑动轴18。
电磁触发机构包括电磁铁4、冲击杆3、固定螺母1、缓冲垫2、电磁铁座5、固定板6，固定板6安装于后侧板13，固定板6上通过螺钉安装电磁铁座5，电磁铁座5上安装电磁铁4。电磁铁4的铁芯与冲击杆3相连而连动，冲击杆3随着铁芯动作，冲击杆3的局部外套压缩弹簧(图3)。弹簧4-1外套于冲击杆3的局部，冲击杆3纵向穿过电磁铁的铁芯4-2，其上端安装缓冲垫2后，再通过固定螺母1定，防止冲击时击杆3脱落；其下端安装缓冲垫4-4，通过冲击螺钉头4-5固守，防止上行复位过程中的冲击。
锁钩29形成锁钩冲击平面291、安全开关冲击面292、锁钩直线斜面293、锁钩安装孔294、锁钩圆弧面295、钩槽296，通过锁钩安装孔294安装于锁钩架30上，当冲击杆3冲击到锁钩冲击平面291时，锁钩29绕锁钩架30转动，使得直线斜面293滑动，使钩槽296脱开对滑动轴18的锁定，此时向下行动的锁钩其安全开关冲击面292触发安全开关12。当复位时，锁钩向上运动，锁钩圆弧面295与滑动轴18接触，使钩槽296锁定滑动轴18；当电机17退回时，滑动轴18在蓄能弹簧17的作用向上运动，使锁钩圆弧面295与滑动轴18接触，此时锁钩不能转动，从而锁定滑动轴18。
当电磁铁4失电时，电磁铁4失去电磁力，冲击杆3在压缩弹簧的带动下作冲击向下运动，通过弹簧力及自重产生冲击作用，使锁钩29脱开，释放压缩的蓄能弹簧17。
安全开关12安装于后侧板13上，当电磁铁的冲击杆3冲击锁钩29时，锁钩29向下运动就能打开安全开关12，通过安全开关12接入电梯安全电路，实现对电梯的整机控制。安全开关冲击面292触碰安全开关12的触点，安全开关接入电梯控制系统的安全回路，安全回路断开，系统停止工作。
本发明钢丝绳制动器的其它内容可参考电梯曳引绳制动器(专利号：ZL200510061286.5)，在此不再详述。
本发明自动复位的钢丝绳制动器包括：电机丝杆推块复位机构、摩擦动/定制动衬板机构、电磁触发机构、电磁铁自动复位机构等，其是一种将原上行超速保护装置的功能升级，实现上行超速保护与轿厢意外移动保护功能合二为一的安全保护装置，并改进电触发为失电触发，采用电机丝杆推块复位机构、摩擦动/定制动衬板机构、电磁触发机构、电磁铁自动复位机构和控制器形成对电梯上行超速和轿厢意外移动保护。当上行超速或轿厢意外移动时，通过控制器的逻辑关系运算，输出控制信号使电磁触发机构的电磁铁失电，触发钢丝绳制动器的锁钩，钢丝绳制动器动作。当复位时，电机丝杆推块复位机构的电机通电，通过推块压滑动轴，连动锁钩和电磁铁复位机构，实现蓄能弹簧、锁钩和电磁铁三者自动复位。本发明具有功能更完善、响应快、稳定可控、安装方便、制造成本低等特点。
以上对本发明的优选实施例进行了详细说明，对本领域的普通技术人员而言，依据本发明提供的思想，在具体实施方式上会有改变之处，而这些改变也应视为本发明的保护范围。
