The invention provides a cover plate opening and closing device. The cover plate opening and closing device comprises at least two fixing shafts and a cover plate, wherein the fixing shafts can be connected with a cable trench; the at least two jacking rods extend in the width direction of the cable trench, the middles of the at least two jacking rods are hinged to the at least two fixing shafts respectively, the first ends of the jacking rods are provided with cover plate matching parts, and the connecting rods are hinged to the second ends of the at least two jacking rods respectively. When the jacking assembly is in the storage state, the cover plate matching part can upwards extend out of the cable trench, and when the jacking assembly is in the storage state, the cover plate matching part can be downwards stored in the cable trench; the mounting shaft can be connected with the cable trench, the middle of the handle part is hinged to the mounting shaft, the first end of the handle part extends out of the cable trench, and the second end of the handle part is in driving connection with the connecting rod. Through the technical scheme provided by the invention, the problems that the cable trench cover plate is difficult to open and close and the safety is relatively low when the weight of the cable trench cover plate is relatively heavy in the prior art can be solved.

    本发明提供了一种盖板开关装置,该盖板开关装置包括:至少两个固定轴能够与电缆沟连接;至少两个顶升杆均沿电缆沟的宽度方向延伸,至少两个顶升杆的中部分别与至少两个固定轴相铰接,顶升杆的第一端设置有盖板配合部,连杆分别与至少两个顶升杆的第二端铰接,当顶升组件处于顶升状态时,盖板配合部能够向上伸出于电缆沟,当顶升组件处于收纳状态时,盖板配合部能够向下收纳至电缆沟内;安装轴能够与电缆沟连接,把手件的中部与安装轴铰接,把手件的第一端延伸至电缆沟外,把手件的第二端与连杆驱动连接。通过本申请提供的技术方案,能够解决相关技术中的在电缆沟盖板重量较大时电缆沟盖板不易进行启闭操作且安全性较低的问题。
