The invention relates to the technical field of cable trench inspection, and discloses a well cover plate opening device for cable trench inspection. The well cover plate opening device for cable trench inspection comprises a cross beam and a well cover plate, wherein side plates are fixedly connected to the left end part and the right end part of the cross beam in a vertically downward manner separately; two horizontally-aligned concentric-square-shaped sliding blocks are movably connected to the cross beam in a sleeving manner; and a rectangular hanging rod is fixedly connected to the middleposition of the bottom of the concentric-square-shaped sliding block in a vertically downward manner. According to the invention, a crank is rotated anticlockwise to drive a jack adjusting lead screwto rotate so as to drive two rhombus jacks to contract, so that the state that the rectangular lifting rod descends to be inserted into an open lifting hole of the well cover plate, is guaranteed, asupporting rod rotates to reach a horizontal state below the well cover plate, then an operator rotates the crank clockwise to drive the jack adjusting lead screw to rotate, and the two rhombus jacksare driven to expand, so that the state that the side plates are jacked up, and then the well cover plate is lifted up, is guaranteed, the operation is convenient and fast, and the operator does not need to carry the well cover plate manually, so that the time and labor are saved.

    本发明涉及电缆沟检查技术领域,公开了一种电缆沟检查井盖板开启装置,包括横梁和井盖板,所述包括横梁左右两端部均竖直向下固定连接有侧板,位于所述横梁上活动套接有两个水平对齐的回型滑块,回型滑块底部中间位置竖直向下固定连接有矩形吊杆。本发明逆时针旋转摇把带动千斤顶调节丝杆进行旋转从而带动两个菱形千斤顶进行收缩,从而保证矩形吊杆下降插接在井盖板的开启吊孔内,托杆在井盖板下方旋转水平状态,然后操作人员顺时针旋转摇把带动千斤顶调节丝杆旋转,从而带动两个菱形千斤顶进行扩张,从而保证对侧板进行顶起,进而将井盖板进行提取上来,操作方便快捷,无需操作人员进行动手搬运井盖板,省时省力。
