A gun hole fishing device

Abstract

The invention discloses a salvaging machine applicable to a blast hole, belongs to the technical field of a salvaging device, and aims to solve the problem that a rope-like material such as a measuring rope or a shock-conducing tube which falls into a hole is hard to salvage during mining work. The invention provides the salvaging machine applicable to the blast hole; the salvaging machine comprises a salvaging machine body; the salvaging machine body comprises a semispherical top, a cylindrical middle part and a conical bottom, wherein a rope tying ring is arranged on the semispherical top; more than five side hooking claws are arranged on the sidewall of the cylindrical middle part; the salvaging machine applicable to the blast hole also comprises more than three bottom hooking claws; each bottom hooking claw is provided with a bottom hooking claw ring lug which is connected with a connecting ring lug arranged at the conical bottom. The salvaging machine applicable to the blast hole disclosed by the invention can be used for salvaging out the measuring rope, the shock conducting tube and the like which falls into the hole so as to realize reutilization, and therefore waste of instruments is reduced. The salvaging machine applicable to the blast hole is especially applicable to a deep-water blast hole of a mine.

Description

technical field [0001] The invention specifically relates to a gunhole overhauler, which belongs to the technical field of overhauling devices. Background technique [0002] At present, in mine production work, there are often measuring ropes or borehole tubes that accidentally fall into the blast hole. Since the depth of the blast hole often reaches more than 10 meters, and there is often water in the hole, it is very difficult to get under the general hook. It is difficult to take out the measuring rope or detonating tube that fell into the hole, which is not only a waste of equipment but also affects subsequent construction. Contents of the invention [0003] Therefore, the object of the present invention is to solve the problem that rope-like items such as measuring ropes or nonel tubes falling into the hole in the current mine work are difficult to salvage, and provide a blast hole overshot, including the overshot body, the overshot The body includes a hemispherical ...
