Description

AXIS-MOVING SOCKET WRENCH

The present invention relates to an axial movement socket wrench used for fastening and disassembling a step bolt, which is a foothold used when a person boards a transmission tower, electric pole, and other structures.

Step bolts are generally installed on transmission towers and utility poles to ensure the safety of workers when working at heights. These step bolts are designed to be installed detachably at an appropriate interval from the structural members of the tower.

The above step bolts are installed in a number of places at appropriate intervals along the length of the transmission tower and electric pole, and serve as a kind of stepping stone that allows workers to step on and go up or down.

To this end, the step bolt is configured to include a male thread portion that can be fastened to a female thread hole formed in a transmission tower and an electric pole, a stem portion that extends from the male thread portion and allows a worker to step on it with his or her foot, and a hexagonal bolt head portion formed at the end of the stem portion. Accordingly, a worker can fasten the male thread portion to the female thread hole of a transmission tower and an electric pole or loosen and remove the male thread portion from the female thread hole by holding the head portion with a hand tool and rotating it.

However, power tools are not generally used to install step bolts on transmission towers and poles. When installing step bolts using power tools, there is a difficulty in securing the bolt head during the process of tightening the nut because the structure has a nut between the bolt head and the structure, rather than a structure between the bolt head and the nut that is commonly used. Therefore, the worker installs the step bolt by engaging two wrenches, one on the bolt head and the other on the nut or the other on the nut (Fig. 1). At this time, the worker must use both hands or two workers must work, and there is a risk of safety accidents depending on the working environment, such as the slope of the work platform, and in addition, there is a lack of efficiency compared to other processes that use power tools.

The present invention provides an axial movement socket wrench including a housing, a first gear, a second gear, a bolt head fixing portion, and a driving unit fixing portion.

The solutions to the problems of the present invention are not limited to those mentioned above, and other solutions not mentioned will be clearly understood by those skilled in the art from the description below.
