The invention discloses a labor-saving well lid grabbing tool and an operation method, and belongs to the technical field of rain sewage pipe network construction tools. The device is provided with amain frame body, a fixed sleeve, a driving device, a movable rod and a clamping jaw, wherein the driving device comprises a bidirectional screw rod, an internal thread, a grip, a forward rotation operating handle, a reverse rotation operating handle, a forward rotation wire spool and a reverse rotation wire spool, and the forward rotation operating handle drives the bidirectional screw rod to rotate forward through a connecting rope; then, the movable rod moves towards the middle part in the fixed sleeve through the threaded transmission of the internal thread and the bidirectional screw rod,so that the well lid is clamped by the clamping jaw, and at the moment, the internal thread and the bidirectional screw rod are locked at the current position due to the self-locking characteristic; when the well lid needs to be lowered, the bidirectional screw rod can be turned over by operating the reverse rotation operating handle, then the movable rod is driven to move towards two sides of thefixed sleeve, and the clamping jaw loosens the well lid; and the operation process is simple and easy to implement, and capable of saving labor, increasing safety and accelerating construction efficiency.

    本发明公开了一种井盖省力抓取工具及操作方法,属于雨污水管网施工工具的技术领域。设有主架体、固定套管、驱动装置、活动杆、夹爪,驱动装置包括双向螺杆、内螺纹、握把、正转操作柄、反转操作柄、正转绕线盘和反转绕线盘,利用正转操作柄通过连接绳带动双向螺杆正转,随后通过内螺纹和双向螺杆的螺纹传动使得活动杆向固定套管内的中部移动,进而实现夹爪夹紧井盖,此时内螺纹和双向螺杆由于自锁特性将锁止在当前位置处,当需要下放井盖时可以通过操作反转操作柄实现其双向螺杆的翻转进而将带动活动杆向固定套管两侧移动,实现夹爪松开井盖,该操作过程简单易行且省力、增加安全性、加快施工效率。
