Description

Fishing tool

Technical Field

The invention relates to the technical field of deep well fishing tools, in particular to a fisher.

Background

The well drilling machine is mainly used for developing underground water resources, comprises well drilling work of domestic water, agricultural water, industrial water and the like, and is particularly commonly used in remote mountain areas or regions with no popularization of tap water in drought and the like. Meanwhile, the method is also suitable for the fields of hydrogeological exploration, building engineering, bridge foundation punching and the like.

In the pipe laying construction operation after the deep water well is drilled for hole forming, accidents that a well pipe falls into a hole due to misoperation often occur, accidents that a rotating rod is twisted off when a bridge pile hole or a drilling hole is drilled also occur, if the well pipe is not fished up in time, large economic loss can be caused, and if the well pipe falls into the hole in the time process, hole collapse or hole well scrapping is easily caused, so that the economic loss can be caused, and meanwhile, normal construction operation plans and construction processes are delayed, and common fishing equipment is low in efficiency and inconvenient to operate.

Based on this, the invention develops a fisher.

Example (b):

as shown in the figures 1-2 of the drawings,

a fisher comprises a fisher body 1 with a hollow tubular structure, a cover beam 3 is arranged at the top end part of the fisher body 1, a first hanging ring structure 2 is fixedly connected on the bent cap 3, a second hanging ring structure 12 which is vertical to the first hanging ring structure 2 is also connected at the central part of the first hanging ring structure 2, the tail end of the fisher body 1 is provided with a guide rib structure 5, the periphery of the fisher body 1 is respectively provided with a fixed alloy body cutter 4 and a movable alloy structure, the movable alloy structure comprises a large triangular iron plate 6 and a small triangular iron plate 7 respectively, the small triangular iron plate 7 is arranged on the inner side of the large triangular iron plate 6, the fisher body 1 at the side of the large triangular iron plate 6 is connected with a movable alloy cutter body 9 through a hinge 8, the front end of the movable alloy knife 9 is provided with an extension spring 10, and the other end of the extension spring 10 is fixed on the large triangular iron plate 6.

The first lifting ring structure 2 and the second lifting ring structure 12 are both semi-circular structures, and are convenient for mechanical pulling during fishing operation. The length of the cover beam 3 is larger than the diameter of the section of the fisher body 1, and the sinking depth of the fisher can be controlled by matching the lifting ring structure 2 through mechanical control. The direction muscle structure 5 is connected in the reinforcing bar of an organic whole by 1 end connection of fisher body and extension and constitutes, the reinforcing bar is equipped with and is no less than four, connects comparatively firmly. The fixed alloy body cutters 4 and the movable alloy structures are arranged in two groups along the periphery of the fisher body 1, and each group is provided with two cutters which are convenient to clamp with a salvaged pipe body.
