The invention relates to the technical field of installation and construction of cable trench cover plates, in particular to a hoisting device for a heavy prefabricated cable trench cover plate, which comprises a hoisting probe rod used for being matched with a cover plate hoisting hole, the lower end of the hoisting probe rod is used for penetrating through the hoisting hole, and the lower end of the hoisting probe rod is provided with an opening and closing mechanism used for supporting the cover plate; the opening and closing mechanism comprises a plurality of bearing claws which are movably arranged on the hoisting probe rod, and the bearing claws stretch out of the hoisting probe rod or withdraw from the hoisting probe rod under the control of the driving assembly; and a traction rope is arranged at the upper end of the hoisting probe rod. The cover plate is supported and hoisted through outward extension of the bearing claws, the hoisting probe rod is withdrawn from the hoisting hole through retraction of the bearing claws, the operation convenience and reliability can be improved for hoisting construction of the cover plate without a hoisting ring, meanwhile, the structure of the cover plate is simpler, and the service life of the cover plate is prolonged.

    本发明涉及电缆沟盖板的安装施工技术领域,具体涉及一种用于重型预制电缆沟盖板的起吊装置,包括用以配合盖板吊装孔的起吊探杆,起吊探杆的下端用以穿过吊装孔,且起吊探杆的下端设置有开合机构用以承托盖板;所述的开合机构包括若干活动设置于起吊探杆的承托爪,承托爪在驱动组件的控制下伸出起吊探杆或收回起吊探杆;所述的起吊探杆的上端设置有牵引索。本发明通过承托爪的外展实现对盖板进行支撑起吊,通过承托爪的收回实现起吊探杆从吊装孔退出,用以对无吊环盖板的吊装施工可提高操作的便捷度和可靠性,同时盖板的结构也更为精简,有利于延长盖板的使用寿命。
