 本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明作进一步详细说明，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
如图1和图2所示，本发明的城市轨道交通站台门系统绝缘门槛装置，包括分别位于站台门15两侧且间隔一定距离的站台门槛绝缘系统和轨道门槛绝缘系统站台门。所述站台门槛绝缘系统包括通过第一螺钉和螺母连接在一起的站台侧踏步板1、站台侧绝缘隔离板3、站台侧门槛基板5。所述轨道门槛绝缘系统包括通过第二螺钉和螺母连接在一起的轨道侧踏步板2、轨道侧绝缘隔离板4和轨道侧门槛基板6。
其中，站台侧绝缘隔离板3位于站台侧踏步板1的下方，站台侧门槛基板5位于站台侧绝缘隔离板3的下方；轨道侧绝缘隔离板4位于轨道侧踏步板2的下方，轨道侧门槛基板6位于轨道侧绝缘隔离板4的下方。并且，站台侧踏步板1和轨道侧踏步板2位于同一水平面上，二者间隔一定距离，中间设有站台门滑动导靴滑槽12，起站台门滑动导向作用。
所述第一螺钉和第二螺钉可以是焊接在站台侧踏步板1和轨道侧踏步板2的下表面的双排种焊钉，所述站台侧绝缘隔离板3、站台侧门槛基板5以及轨道侧绝缘隔离板4和轨道侧门槛基板6上均开设圆孔，圆孔的位置与种焊钉的位置对应，圆孔内设有绝缘套7，所述种焊钉从绝缘套7的中心孔穿过与站台侧门槛基板5以及轨道侧门槛基板6下部的螺母旋接从而可将站台门两侧的踏步板、绝缘隔离板和门槛基板固定连接在一起。此处的绝缘套7优选横截面呈T形的绝缘套，以便将种焊钉和螺母与站台侧门槛基板5和轨道侧门槛基板6完全绝缘隔离。至此，站台侧踏步板1与站台侧门槛基板5，轨道侧踏步板2与轨道侧门槛基板6完全绝缘隔离，门槛外表面本身具有自绝缘性能。
本发明的站台侧踏步板1、站台侧绝缘隔离板3、站台侧门槛基板5、轨道侧踏步板2、轨道侧绝缘隔离板4和轨道侧门槛基板6的横截面均呈倒U形。所述轨道侧踏步板2靠近站台门15一侧的侧边底部处设有翻边21，该翻边21延伸至站台侧踏步板1靠近站台门15一侧侧边的正下边。设置翻边21可以防止异物通过两块踏步板之间的滑槽掉落进站台土建槽或者掉落进轨道。并且，翻边21与站台侧踏步板1靠近站台门15一侧的侧边之间可以留有缝隙，以便使灰尘等细小尘埃不积留在门槛滑槽内。
所述站台侧踏步板1、站台侧绝缘隔离板3和站台侧门槛基板5靠近站台门一侧的侧边依次贴合定位安装，三者靠近站台一侧的侧边之间留有间隙。该间隙可以吸收站台侧踏步板1、站台侧绝缘隔离板3和站台侧门槛基板5的直线度误差，便于整体组装，且不影响门槛性能。所述轨道侧踏步板2、轨道侧绝缘隔离板4和轨道侧门槛基板6靠近轨道侧的侧边依次贴合定位安装，三者在靠近站台门一侧的侧边之间也留有间隙，也可吸收三者之间的直线度误差。
本发明的站台侧门槛基板5和轨道侧门槛基板6的下表面通过门槛连接板8焊接成一个整体并作为门槛的承重结构。站台门系统的站台门立柱的下表面与立柱底部基板14焊接成一个整体作为站台门的承重结构。在站台侧门槛基板5和轨道侧门槛基板6的下方焊接哈芬槽9，在哈芬槽9内放置方形螺母10，将螺栓从立柱底部基板14的底部向上穿插旋拧进方形螺母10中，可将整个站台门系统的绝缘门槛装置与承重结构立柱13之间固定连接。由于采用哈芬槽9的连接方式，方形螺母10可以在哈芬槽9中左右滑动，可以吸收加大的安装误差，使得整个绝缘门槛装置安装方便、易于操作。
如图3所示，本发明的站台侧踏步板1和轨道侧踏步板2可以选用不锈钢材制作，其上表面可采用冲压工艺，形成第一凹凸相间结构101，起到防滑作用。所述站台侧绝缘隔离板3和轨道侧绝缘隔离板4可以选用复合绝缘板制作，其上、下表面均为锯齿形结构102，可以增大站台侧绝缘隔离板3与站台侧踏步板1和站台侧门槛基板5、以及增大轨道侧绝缘隔离板4与轨道侧踏步板2和轨道侧门槛基板6之间的摩擦力。站台侧门槛基板5和轨道侧门槛基板6可以选用钢基板制作，增强两者的承重性能。
如图1所示，因轨道限界要求，某些站台门系统中，门槛轨道侧边缘与列车车身之间的距离较大，为防止距离较大而使乘客出现踏空的情况，可以在门槛边缘安装防踏空胶条装置11，该防踏空胶条装置11的上表面与轨道侧踏步板2平齐，其外侧面上开有圆孔，所述轨道侧门槛基板6的侧边上焊接有螺母，该防踏空胶条装置11通过螺栓与螺母的连接与轨道侧门槛基板6固定连接。
如图4和图5所示，所述防踏空胶条装置11包括复合绝缘橡胶和碳钢基板，碳钢基板可以增加胶条的强度，提高防踏空胶条装置11的承载能力，整个碳钢基板内嵌在复合绝缘橡胶内，整个防踏空胶条装置11自身绝缘。该复合绝缘橡胶靠近轨道的一侧为第二凹凸相间结构103，该第二凹凸相间结构103区域不含任何钢件，当列车过站车身摆幅较大时，如果车身与防踏空胶条装置11接触，此种设计可以使胶条被压缩，避免对车身造成损伤。
本发明的优势在于：
1、通过设置站台侧绝缘隔离板3、轨道侧绝缘隔离板4和绝缘套7，使门槛外表面本身具有自绝缘性能；
2、轨道侧踏步板2设有翻边21，可以防止异物落进站台土建槽或者掉落进轨道；
3、站台侧踏步板1和轨道侧踏步板2的上表面设有第一凹凸相间结构101可起到防滑作用；
4、站台侧绝缘隔离板3和轨道侧绝缘隔离板4的上、下表面为锯齿形结构102，可以增加摩擦力；
5、复合绝缘橡胶靠近轨道的一侧为第二凹凸槽型结构103，可以避免防踏空胶条装置11对车身造成损伤。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有何种更改和变化。凡在本发明的精神和原则之内所做的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
