为了更清楚地说明本发明实施例，下面将对照附图说明本发明的具体实施方式。显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，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，并获得其他的实施方式。
目前的电梯控制系统，大多通过监测曳引驱动及制动器对电梯轿厢的联动控制，由于曳引驱动、悬挂及制动以确保电梯的安全都是间接的，不是直接监测与控制电梯轿厢的安全。基于此，本发明开发的电梯轿厢安全的紧急保护系统，所有的检测、控制均源于电梯轿厢，曳引驱动及制动器仅作为电梯运行的执行部件，电梯的安全、控制、保护都是使电梯轿厢安全可靠且稳定运行，实现安全乘梯。以下将通过具体实施例进行详细说明：
实施例一：
如图1和2所示，本实施例的电梯轿厢安全的紧急保护系统，包括全部安装在电梯轿厢上的检测触发装置A、带提拉力的提拉装置B和紧急制动装置C。
其中，检测触发装置A，用于通过滚轮与电梯导轨I接触，便于检测触发装置A准确地检测电梯轿厢的状态，检测触发装置A还用于在电梯轿厢处于故障状态时触发带提拉力的提拉装置B。具体地，如图3-6所示，检测触发装置A包括检测器1和触发机构2，检测器1用于检测电梯轿厢的状态，并在电梯轿厢处于故障状态时驱动触发机构2；本实施例的检测器1为机械式检测器，即限速器，故本实施例的检测器检测的电梯轿厢的状态为电梯轿厢的运行速度，继而本实施例的电梯轿厢的故障状态为超速或坠落或意外移动等能够通过速度反馈的故障状态，例如，超速的故障状态为电梯轿厢的运行速度超出电梯额定速度的115％、坠落、意外移动的故障状态可以通过运行速度的异常反馈。如图5所示，检测器1位于滚轮11上，滚轮11用于与电梯导轨I接触，通过接触的方式使得检测器检测得到的电梯轿厢的状态更准确。另外，检测器1不限于检测电梯轿厢的运行速度，还可以检测其运行速度、位移、振动、加速度、行程中的一种或多种。
当检测器1检测到电梯轿厢的状态属于故障状态时，限速器动作联动触发机构2。其中，如图3所示，触发机构2包括驱动件21、转动轴22和联动杆23，驱动件21用于被限速器触发而活动；转动轴22的横截面为方形，相应地，驱动件21具有与转动轴22的横截面结构相配的方孔，当驱动件21安装在转动轴22上，转动轴22能联动于驱动件21；联动杆23具有与转动轴22的横截面结构相配的方孔，当联动杆23安装在转动轴22上，联动杆23能够联动于转动轴22。而且，驱动件21绕转动轴22转动的转动面与联动杆23绕转动轴22转动的转动面相互平行；如图7所示，联动杆23为组件式设计，包括杆体231、套筒232和连杆233，套筒232套设在杆体231之外，且两者通过压簧234相配，杆体231通过基座安装在转动轴22上，使得杆体231联动于转动轴22；连杆233与套筒232之间的连接结构为凹凸配合结构，且连杆233抵靠于杆体231，使得杆体231活动时能联动连杆233活动。
另外，为了便于触发机构的复位，如图4和5所示，本实施例的触发机构还包括复位组件24，复位组件24包括第二转动盘241、第二安装板242、第三活动板243、第四活动板244、第二导向柱245和第二复位弹性件246，第二转动盘241联动于转动轴22，第二安装板242通过安装架a固定于电梯轿厢，且第二转动盘241转动配合于安装架a；具体地，在第二转动盘241的外壁开设有圆环槽，相应地，安装架a上开设有圆孔，安装架的圆孔装配在第二转动盘的圆环槽内，使得第二转动盘可以转动配合于安装架。其中，第二安装板242用于安装第三活动板243和第四安装板244，其安装的方式可以为榫接，以使第三活动板243、第四安装板244分别位于第二转动盘241的两侧；更为具体地，第二转 动盘241的转动面设有四根复位螺栓2410，四根复位螺栓2410呈方形分布，第三活动板243和第四安装板244分布位于四根复位螺栓2410的两侧，使得第二转动盘241转动时，其上的四根复位螺栓2410能够联动第三活动板243、第四活动板244活动。第二导向柱245安装在第三活动板243和第四活动板244之间，且延伸至第四活动板244之外构成第二延伸段，第二复位弹性件246套设在第二导向柱245的第二延伸段并通过螺母限位；当第二转动盘241转动时，第二转动盘241上的四根复位螺栓能够联动第三活动板243、第四活动板244活动，从而使得第四活动板244压缩第二复位弹性件246，使得第二复位弹性件246处于压缩状态，便于触发机构的复位。其中，第二导向柱245为长螺栓，贯穿第三活动板243和第四活动板244；第二复位弹性件246为复位弹簧或其它具有弹性的零部件。
其中，带提拉力的提拉装置B，用于在被触发时与电梯导轨接触摩擦以产生提拉力，并触发制动装置C；具体地，如图8所示，带提拉力的提拉装置B包括提拉力机构3和连动机构4，提拉力机构3与连动机构4连接，提拉力机构3被触发时与电梯导轨接触摩擦以产生提拉力，从而联动连动机构以触发紧急制动装置。如图9所示，提拉力机构3的结构同安全钳的结构，包括座体31，座体31具有纵向设置的导轨槽310，电梯导轨I贯穿于导轨槽310，导轨槽的一侧设置与座体31连接的楔块32，楔块32的表面设有摩擦片；导轨槽的另一侧设置与座体31活动连接的抵靠件33。具体地，座体31具有与抵靠件33相适配的滑道，使得抵靠件33能够活动配合于滑道，滑道包括连通的上滑道3110和下滑道3111，上滑道3110和下滑道3111均以两者的连通位置为起点，朝导轨槽所处的方向并向两侧延伸，从而使得抵靠件33沿上滑道3110或下滑道3111活动均能使抵靠件33从与电梯导轨间隙配合至接触配合，从而使抵靠件33与电梯导轨I接触摩擦而产生提拉力，还能实现双向触发。其中，如图11和12所示，抵靠件33与联动杆的连杆233通过限位销轴235、垫片236及螺钉237连接，使得联动杆23能够联动抵靠件33沿上滑道3110或下滑道3111活动。另外，本实施例的抵靠件33为滚柱。
另外，本实施例的提拉力机构3还包括限位组件，如图9和10所示，限位组件包括限位柱34、套设在限位柱34之外的上滑套35、下滑套36、上限位弹性件37和下限位弹性件38，上滑套35和下滑套36上下分布并与提拉力机构的座体31固定连接，限位柱34贯穿上滑套35和下滑套36，限位柱34的上端套设上限位弹性件37并通过螺母限位，使得上限位弹性件37的上下端分布限位在上滑套35与上螺母之间；限位柱34的下端套设下限位弹性件38并通过下螺母限位，使得下限位弹性件38的上下端分布限位在下滑套36与下螺母之间。限位柱34的下端通过固定支架固定在电梯轿厢上。当提拉力机构的抵靠件33 与电梯导轨接触摩擦时，提拉力机构的座体31的活动通过上限位弹性件37和下限位弹性件38限位，还能实现缓冲的作用。本实施例的上限位弹性件37和下限位弹性件38均为限位弹簧或其它具有弹性的零部件。
如图12所示，本实施例的连动机构4，包括提拉杆41和联动组件42，提拉杆41由若干连杆依次连接而成，不限于图中的直角结构，以便避让电梯轿厢的结构；提拉杆41的上端与提拉力机构的座体31连接以实现联动而传递提拉力，提拉杆41的下端与联动组件42联动，联动组件42联动制动装置C以触发制动装置C。具体地，如图13所示，联动组件42包括转轴421、触发板422，转轴421为方管结构，转轴421通过提拉板423连接于提拉杆41的下端，从而实现转轴421联动于提拉杆41，触发板422联动于转轴421，触发板422联动制动装置C以触发制动装置C。
另外，为了实现连动机构的复位，联动组件42还包括复位机构，复位机构用于转轴的复位。具体地，如图13和14所示，复位机构包括第一转动盘424、第一安装板425、第一活动板426、第二活动板427、第一导向柱428和第一复位弹性件429，第一转动盘424联动于转轴421，第一安装板425通过安装支架b固定于电梯轿厢，且第一转动盘424转动配合于安装支架b；具体地，在第一转动盘424的外壁开设有圆环槽，相应地，安装支架b上开设有圆孔，安装支架的圆孔装配在第一转动盘的圆环槽内，使得第一转动盘可以转动配合于安装支架。其中，第一安装板425用于安装第一活动板426和第二安装板427，其安装的方式可以为榫接，以使第一活动板、第二安装板分别位于第一转动盘的两侧；更为具体地，第一转动盘424的转动面设有四根复位螺栓4240，四根复位螺栓呈方形分布，第一活动板和第二安装板分布位于四根复位螺栓4240的两侧，使得第一转动盘424转动时，其上的四根复位螺栓4240能够联动第一活动板、第二活动板活动。第一导向柱428安装在第一活动板和第二活动板之间，且延伸至第二活动板之外构成第一延伸段，第一复位弹性件429套设在第一导向柱428的第一延伸段并通过螺母限位；当第一转动盘转动时，第一转动盘上的四根复位螺栓能够联动第一活动板、第二活动板活动，从而使得第二活动板压缩第一复位弹性件429，使得第一复位弹性件429处于压缩状态，便于连动机构的复位。其中，第一导向柱为长螺栓，贯穿第一活动板和第二活动板；第一复位弹性件为复位弹簧或其它具有弹性的零部件。
其中，如图15所示，本实施例的联动组件42有两个(数量不限于两个，制得装置的数量而定)，每个联动组件均与一个制动装置C联动，两个联动组件的转轴连接以实现同步转动，从而实现电梯轿厢的稳定制动。其中，只有一个联动组件的转轴与提拉杆通过提拉 板连接，另一个联动组件的转轴通过与提拉杆连接的联动组件的转轴同步联动。
本实施例的紧急制动装置用于在被触发时制动电梯轿厢，包括接触(例如：夹持)电梯导轨而产生制动力的制动装置，例如单向安全钳或双向安全钳，也可以是其它夹轨制动装置或之外的紧急保护装置。本实施例的紧急制动装置的具体结构同提拉力机构的具体结构(不包括限位组件)，在此不赘述。
本实施例的电梯轿厢安全的紧急保护系统，可以通过电梯轿厢的逆行实现制动装置的复位，从而联动提拉装置复位。
本实施例的电梯轿厢安全的紧急保护系统，所有的检测、控制均源于电梯轿厢，曳引驱动及制动装置仅作为电梯运行的执行部件，电梯的安全、控制、保护都是使电梯轿厢安全可靠且稳定运行，实现安全乘梯。
实施例二：
本实施例的电梯轿厢安全的紧急保护系统与实施例一的不同之处在于：
如图16和17所示，本实施例的检测器包括机械检测器100和电子检测器200，即机械限速器和电子限速器，机械式检测器100与电子式检测器200分别位于电梯导轨的两侧，且机械式检测器100和电子式检测器200的滚轮具有一定的预紧力与电梯导轨接触，并始终夹持电梯导轨；机械检测器用于检测电梯轿厢的速度、位移，电子检测器用于检测电梯轿厢的速度、位移、加减速度、行程、振动等。机械检测器的驱动件与电子检测器的驱动件联动，通过同一联动杆联动提拉力机构，本实施例的提拉力机构300也进行了改进，当然也可以采用实施例一的提拉力机构。
本实施例的提拉力机构300包括座体、U型板簧和两套限位组件，座体位于U型板簧的中部，且通过座体两侧的四根导柱安装在U型板簧内，导柱外套设缓冲弹簧310，使得对座体的活动进行限位及缓冲。两套限位组件分别固定于U型板簧的两侧，固定的方式参考实施例一；座体具有纵向设置的导轨槽，电梯导轨贯穿于导轨槽，导轨槽的一侧设置与座体连接的楔块，导轨槽的另一侧设置与座体活动连接的抵靠件；当电梯轿厢的状态处于故障状态时，联动杆联动抵靠件活动至与电梯导轨接触。
电子检测器的具体的实施方式可以为：在滚轮上安装电磁铁，通过旋转轮转动使得电磁铁旋转，通过磁编码器实现速度、位移、加减速度、行程等的测量，通过校准开关对运行状态监测(检验及紧急制动)、通过触发状态监测记录安全部件动作资料，通过运行状态监测记录数据，通过无线传输记录数据，使用维护保养与紧急处理联动；还在滚轮上安装 振动传感器，用于检测轿厢的振动。本实施例将机械与电气双重冗余安全保护相互判定实现更加安全控制；当然，其它编码器(例如光电编码器)也能实现上述功能。本实施例能实现将电梯轿厢的位置检测采用位置开关检测方式转变成通过位置测量的方式来控制轿厢门区位置，简化了采用位置开关检测方式的电梯结构。
其它结构可以参考实施例一。
实施例三：
本实施例的电梯轿厢安全的紧急保护系统与实施例一的不同之处在于：
本实施例的电梯轿厢安全的紧急保护系统，还包括云服务器和显示终端，云服务器实时接收各电梯对应的检测器检测的电梯轿厢的运行数据，显示终端通过地图显示的方式显示各电梯的定位、实时运行状态、维保数据等；当某一电梯处于故障状态，显示终端能实时显示并产生报警，从而提高解决电梯故障的效率以及保障人身安全。
其它结构可以参考实施例一。
实施例四：
本实施例的电梯轿厢安全的紧急保护系统与实施例一的不同之处在于：
省略带提拉力的提拉装置的结构，直接由检测触发装置在电梯处于异常运行时触发紧急制动装置，虽然简化了整个系统的构架，但是对检测触发装置的触发力要求较高，适用于特殊的场合以满足用户的不同需求。
其它结构可以参考实施例一。
以上所述仅是对本发明的优选实施例及原理进行了详细说明，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。
