请参阅图1-7，电梯检修防护安全装置，包括支撑机构1、防护机构2和检修机构3，支撑机构1包括底座101，底座101顶面固定连接有软垫103，软垫103顶面固定连接有踏板102，防护机构2的数量为两个且分别设置在 软垫103顶面两侧，检修机构3的数量为两个且分别设置在两个防护机构2上，防护机构2包括连接座201，连接座201固定连接在软垫103顶面，软垫103上下两面内壁均固定连接有弹簧A104，软垫103内部填充有液压油，连接座201靠近软垫103外侧的一端固定连接有连杆A202，连杆A202正面远离连接座201的一端开设有孔且孔内套入有连杆B203，连杆B203远离连杆A202的一端固定连接有卡爪204，卡爪204呈C字型体且两个卡爪204的凹面相背离，卡爪204前后面的上下两端内壁均固定连接有夹垫2010，连杆A202顶面通过转轴合页固定连接有圆筒A205，圆筒A205靠近连杆B203的一面呈镂空状态且内壁套入有活塞206，活塞206对应连杆B203的一面固定连接有拉杆207，拉杆207远离活塞206的一端通过转轴合页与连杆B203固定连接，活塞206底面通过气管A208与软垫103连通，当维修工人到达电梯顶部时，会首先踩踏在踏板102上，然后踏板102将压力传导到软垫103上，软垫103受力挤压形变，且将其内部的液压油通过气管A208注入到圆筒A205内，圆筒A205内注入的液压油推动活塞206向上滑动，活塞206滑动时通过拉杆207滑动，从而扩大连杆A202和连杆B203顶端的间距，使得连杆B203转动，连杆B203转动后卡爪204与钢索卡合，从而将电梯与钢索相连接，当维修工人脱离对踏板102的踩踏后，弹簧A104回弹带动软垫103复位，从而将圆筒A205内的液压油抽回软垫103中，并通过负压拉动活塞206，从而带动卡爪204脱离钢索并带动连杆B203复位，通过防护机构2的设置，在维修工人踩踏在电梯上方时，自动将卡爪204与钢索相连接，利用钢索对电梯起到限位作用并增加电梯的稳定性，从而对从电梯上方检修的维修工人进行防护，防护过程自动化，使用方便且效率高。
卡爪204前后两侧内部均呈镂空状态，卡爪204前后两侧内壁对应面等间距开设有数个插槽4，卡爪204内部对应插槽4的位置开设有卡槽5，插槽4内套入有滑块2012，滑块2012位于卡爪204内部的一面固定连接有限位板2013，限位板2013位于卡爪204内部的一端固定连接有弹性伸缩件2011，弹性伸缩件2011远离滑块2012的一端与卡爪204内部壁面固定连接，圆筒A205中部通过气管B209与卡爪204前后两侧内部连通，在卡爪204与钢索接触后，软垫103后续挤压出的液压油会通过气管B209注入到卡爪204内部，然后液压油在卡爪204内部推动滑块2012向钢索靠近，卡槽5对滑块2012的伸出距离进行限位，在与钢索对应的滑块2012在与钢索贴合后通过液压油的压力来紧密夹持钢索，而不与钢索对应的滑块2012会与相应位置的滑块2012相互贴合，从而对钢索侧面起到夹持和限位效果，在软垫103回弹并抽回液压油时，滑块2012未收缩回卡爪204内时，卡爪204受到滑块2012与钢索卡合的限制而无法移动，从而避免活塞206提前在圆筒A205内滑动，当滑块2012收缩回卡爪204后，活塞206随着抽回的液压油滑动并带卡爪204和连杆B203复位，通过滑块2012的设置，在卡爪204与钢索套入后，自动伸出来对钢索进行夹持，提高对钢索夹持的强度，从而提高电梯与钢索连接的强度，进一步提高稳定性，且通过与钢索呈不同位置滑块2012的伸出，分别实现对钢索的紧密夹持和对钢索侧位置限位的效果，将钢索的位置限制死，避免钢索随着电梯的施压而晃动，保证维修工人站立区域的稳定，提高维修效率和安全性。
数个滑块2012前后的对应面开设有滑槽6，滑槽6两侧内壁均固定连接有弹簧B2017，弹簧B2017靠近滑槽6中部的一端固定连接有滑柱2014，滑 柱2014与滑槽6内壁呈套入关系，滑柱2014正面固定连接有插板2015，插板2015呈三棱柱体，因为钢索均采用多股钢绳拧成，且拧成的钢绳外壁呈曲面，与钢索位置对应的滑块2012伸出后，插板2015会与钢索中的钢绳接触，然后随着推力使得插板2015顺着钢绳的曲面带动滑柱2014转动和移动，从而使插板2015插入多股钢绳的凹陷处，从而将钢索完全的卡住，通过插板2015的设置，在与钢索对应的滑块2012伸出后，插板2015会顺着拧成的钢绳纹路来改变位置和角度，直到插板2015插入拧成的钢绳间隙中，实现对钢索的完全夹持，大幅提高夹持的稳定性，从而进一步提高电梯与钢索连接的稳定性。
插板2015两侧面均固定连接有气囊2016，气囊2016通过连接管与卡爪204内部连通，滑块2012全部伸出至极限后，后续注入卡爪204内的液压油会注入到气囊2016内，使得气囊2016产生膨胀，通过气囊2016的设置，在卡爪204和插板2015夹持住钢索后，与钢索对应的气囊2016会通过形变来渗入钢绳拧成的纹路中，配合与插板2015进一步增加连接的稳定性，而不与钢索对应的气囊2016膨胀后增加密封程度，从而增加对钢索限位的效果，气囊2016还具备保证钢索不会崩开的好处，当气囊2016对存在断裂风险的钢索进行夹持时，能够通过挤压使得钢绳在受力时不会产生位置上的偏移，从而避免断裂的问题，保证维修人员对电梯检修时不会产生钢索断裂的问题，且方便了维修人员对相应断裂风险的钢索更换。
软垫103顶面开设有孔且孔内通过转动轴承固定连接有螺栓A105，底座101顶面对应螺栓A105的位置开设有螺纹孔且与螺栓A105螺纹连接，通过螺栓A105的设置，维修人员能够通过转动螺栓A105的方式控制软垫103的 伸缩幅度，从而控制装置的启用以及液压油的挤压量，提高装置的适用性和变通性。
检修机构3包括限位板301，限位板301呈C字型体且侧面等间距开设有矩形槽，限位板301顶面和底面均固定连接有固定板302，固定板302侧面开设有螺纹孔且螺纹连接有螺栓B303，卡爪204侧面对应螺栓B303的位置开设有螺纹孔且与螺栓B303螺纹连接，卡爪204侧面对应限位板301的位置开设孔且与限位板301呈套入关系，限位板301与限位板2013对应滑块2012的一面对应，卡爪204正面固定连接且连通有圆筒B304，圆筒B304的内部中空，圆筒B304与气管B209固定连接且连通，圆筒B304顶面固定连接且连通有圆筒C305，圆筒C305顶端开设有孔且孔内套入有滑杆306，卡爪204正面在滑杆306上方固定安装有传感器307，传感器307采用磁铁材质且与圆筒B304相互吸引，首先转动螺栓B303将限位板301插入卡爪204内部，限位板301与限位板2013贴合，从而限制滑块2012的伸出，然后拧紧螺栓B303来将软垫103内的液压油注入到卡爪204内，然后通过卡爪204注入到气囊2016内，气囊2016膨胀后相互贴合且与钢索紧密贴合，在气囊2016充满液压油后，继续拧动至滑杆306伸出并受到传感器307的检测，停止拧动，然后启动电梯的运转，电梯运转时钢索在卡爪204内穿梭，当存在崩裂问题的钢绳插入卡爪204内后，滑杆306回缩并将液压油注入到相应位置的气囊2016内，使得气囊2016继续膨胀来填补钢索的崩裂处，而随着滑杆306的下降，传感器307失去对滑杆306的检测并发送信号，从而实现自动化检测钢索完整性的功能，通过检修机构3的设置，与支撑机构1和防护机构2相互配合，经过简单的操作后即可使得装置的功能由防护电梯上维修工人，切 换为检测钢索完整度，具备不会额外占用过多空间等好处，极大地提高装置的实用性。
在使用时，S1，当维修工人到达电梯顶部时，会首先踩踏在踏板102上，然后踏板102将压力传导到软垫103上，软垫103受力挤压形变，且将其内部的液压油通过气管A208注入到圆筒A205内，圆筒A205内注入的液压油推动活塞206向上滑动，活塞206滑动时通过拉杆207滑动，从而扩大连杆A202和连杆B203顶端的间距，使得连杆B203转动，连杆B203转动后卡爪204与钢索卡合，从而将电梯与钢索相连接，当维修工人脱离对踏板102的踩踏后，弹簧A104回弹带动软垫103复位，从而将圆筒A205内的液压油抽回软垫103中，并通过负压拉动活塞206，从而带动卡爪204脱离钢索并带动连杆B203复位。
S2，在卡爪204与钢索接触后，软垫103后续挤压出的液压油会通过气管B209注入到卡爪204内部，然后液压油在卡爪204内部推动滑块2012向钢索靠近，卡槽5对滑块2012的伸出距离进行限位，在与钢索对应的滑块2012在与钢索贴合后通过液压油的压力来紧密夹持钢索，而不与钢索对应的滑块2012会与相应位置的滑块2012相互贴合，从而对钢索侧面起到夹持和限位效果，在软垫103回弹并抽回液压油时，滑块2012未收缩回卡爪204内时，卡爪204受到滑块2012与钢索卡合的限制而无法移动，从而避免活塞206提前在圆筒A205内滑动，当滑块2012收缩回卡爪204后，活塞206随着抽回的液压油滑动并带卡爪204和连杆B203复位。
S3，因为钢索均采用多股钢绳拧成，且拧成的钢绳外壁呈曲面，与钢索位置对应的滑块2012伸出后，插板2015会与钢索中的钢绳接触，然后随着 推力使得插板2015顺着钢绳的曲面带动滑柱2014转动和移动，从而使插板2015插入多股钢绳的凹陷处，从而将钢索完全的卡住。
S4，滑块2012全部伸出至极限后，后续注入卡爪204内的液压油会注入到气囊2016内，使得气囊2016产生膨胀。
S5，首先转动螺栓B303将限位板301插入卡爪204内部，限位板301与限位板2013贴合，从而限制滑块2012的伸出，然后拧紧螺栓B303来将软垫103内的液压油注入到卡爪204内，然后通过卡爪204注入到气囊2016内，气囊2016膨胀后相互贴合且与钢索紧密贴合，在气囊2016充满液压油后，继续拧动至滑杆306伸出并受到传感器307的检测，停止拧动，然后启动电梯的运转，电梯运转时钢索在卡爪204内穿梭，当存在崩裂问题的钢绳插入卡爪204内后，滑杆306回缩并将液压油注入到相应位置的气囊2016内，使得气囊2016继续膨胀来填补钢索的崩裂处，而随着滑杆306的下降，传感器307失去对滑杆306的检测并发送信号，从而实现自动化检测钢索完整性的功能。
