A heavy cover plate hoisting device for a cable trench of a converter transformer square comprises a hoisting frame, hoisting supporting legs are installed at the bottoms of the four corners of the hoisting frame, universal wheels are installed at the bottoms of the hoisting supporting legs, a plurality of hoisting beams arranged side by side are installed in the hoisting frame, and hoisting bottom plates are installed on the hoisting beams. The hoisting device for the heavy cover plate of the cable trench of the converter transformer square has the positive effects that the perforating hoisting tool can enter the cable trench through a hole in the heavy cover plate, a hoisting support is formed for the bottom of the heavy cover plate, and the hoisting of the heavy cover plate can be realized under the rotation of the winding drum. By using the device, the workload can be effectively reduced, the number of maintainers is reduced, the maintainers are prevented from entering a dark and closed cable trench, the use of special vehicles can be reduced, the operation risk is reduced, and the working efficiency of lifting the whole heavy cover plate is improved.

    换流变压器广场电缆沟重型盖板吊装装置,包括有吊装框架,吊装框架四角的底部位置均安装有吊装支腿,各吊装支腿的底部均安装有万向轮,在吊装框架内安装有若干根并排设置的吊梁,吊梁上安装有吊运底板。本发明的积极效果在于:本发明所述的一种换流变压器广场电缆沟重型盖板吊装装置穿孔吊具能经由重型盖板上的孔洞进入到电缆沟内,并且对重型盖板的底部形成提升支撑,在卷筒的转动下能实现对重型盖板的吊装提升。使用上述装置不仅能有效降低工作量,减少检修人员数量,避免进入到黑暗封闭的电缆沟内行走,还能减少特种车辆的使用,降低操作风险,并提升整体重型盖板提升的作业效率。
