Embodiment 1

[0046] Such as figure 1 Shown, a kind of specific implementation of this hammer head fishing device. It includes a hammer head salvage connection structure 2 connected to the hammer body 1 (a part of the hammer body is shown in the figure) and a matching salvage spreader 3. The figure shows that the hammer head salvage connection structure 2 and the salvage The state that the spreader 3 is mated and connected. see figure 2 , wherein the hammer head salvage connection structure 2 includes a pair of connecting plates 5 fixedly connected to the hammer body 1 as the hanging structure 4, and the lower end is fixedly connected with a pair of connecting plates 5 and connected from the connecting plates 5 The upper end of the rod-shaped salvage connector 6 protruding upwards. Reserve a perforation for driving the hammer body 1 to move up and down between a pair of connecting plates 5 to connect a hanging rope (not shown). In this embodiment, a pulley 7 for connecting the hanging ...

Abstract

The invention provides a hammer head salvage connection structure and a hammer head salvage device. The hammer head salvage connection structure comprises a salvage connecting member arranged on a hammer body, and the hammer body is connected with a hanging rope through a hanging structure; and during the working state, a position, higher than the hanging structure, on the salvage connecting member is provided with a first connecting portion cooperatively connected with a salvage hanging tool. The first connecting portion is arranged on the position, higher than the hanging structure, on the salvage connecting member so as to avoid the problem that sediment covers the salvage connecting member to the greatest extent; and even if the hanging rope breaks, the remaining hanging rope is located below the salvage connecting member, cooperative connection between the salvage hanging tool and the salvage connecting member cannot be affected, and the salvage efficiency is high.

Description

technical field [0001] The invention relates to the technical field of impact hammer fishing, in particular to a hammer head fishing connection structure and a hammer head fishing device. Background technique [0002] The impact hammer consists of a hammer head and a hanging rope connected to the hammer head to drive the hammer head to move up and down. No matter whether the two are connected rigidly or flexibly, since the relative movement between the two is inevitable during work, It also leads to fatigue or wear of the connection between the two, which will cause the connection between the two to fail over time. It is more common for the hammer head to fall off during the construction process. [0003] The traditional fishing device is generally equipped with a fishing ring on the hammer body. A fishing hook similar to a small anchor is used to reach the bottom of the hole, and the wire rope connected to the fishing hook above the hole is kept swinging until the hook of t...
