In order to solve the technical problems, the invention provides the following technical scheme:

a salvaging device comprises a core tube, a salvaging spear and a salvaging tube, wherein the core tube is connected with the salvaging spear when a steel wire cable is salvaged; when salvaging the exploring tube, the core tube is connected and salvages the pipe, salvage the lance through the core tube connection, utilize the fishing lance to salvage the steel wire cable after breaking, after the steel wire cable salvages and accomplishes, take out the fishing lance from the core tube, will salvage pipe and core tube connection again, salvage out the exploring tube through salvaging the pipe, through the device's setting, not only can realize quick convenient salvage the steel wire cable and exploring tube after breaking, improve and salvage efficiency, the device simple structure moreover, easily preparation.

Preferably, the fishing spear is threadedly connected to the core barrel.

Preferably, the trip spear is square steel plate, the steel sheet both sides are equipped with a plurality of zigzag recesses, the opening direction of zigzag recess sets up along the slope of core barrel department.

Preferably, the end of the steel plate far away from the core tube is provided with a pointed shape.

Preferably, the fishing tube is threadedly connected to the core barrel.

Preferably, the fishing pipe is a cylindrical sleeve, a steel wire ring and a plurality of fan-shaped steel wire ropes are arranged in the sleeve, the steel wire ring is welded on the inner wall of the sleeve, one ends of the fan-shaped steel wire ropes are horizontally and uniformly distributed on the steel wire ring, and the other ends of the fan-shaped steel wire ropes are arranged towards the center of the steel wire ring to form a net structure capable of supporting the exploring pipe.

Compared with the prior art, the invention has the beneficial effects that:

through the device's setting, not only can realize quick convenient salvage the steel wire cable and visit the pipe after breaking, improve and salvage efficiency, the device simple structure easily makes moreover.
