Abstract

The application relates to the technical field of water conservancy and hydropower, in particular to a threading tool for a cable well, which comprises a frame base, a frame cantilever, an extension assembly and first and second guide wheels; the frame base is arranged in the cable well, the frame cantilever is fixedly arranged on the frame base, the extension assembly is fixedly arranged on both sides of the frame cantilever, and the extension assembly is used for fixedly abutting against the inner wall of the cable well to fix the position of the frame base; the first guide wheel is arranged on the frame base, the second guide wheel is arranged on the frame cantilever, and the elevation of at least one second guide wheel is higher than the elevation of the plane where the second through hole is located; the cable in the cable well is sequentially arranged around the first and second guide wheels to pull the cable out of the cable well. In the application, the frame base and the frame cantilever are fixed in the cable by using the extension assembly, and the first and second guide wheels of the frame base are used to guide the cable, so that the risk of cable skin abrasion is reduced.
