Description

Auxiliary equipment for moving along transmission lines having a braking guide and a strap fastening structure The present invention relates to an auxiliary facility for moving along a transmission line, and more specifically, to an auxiliary facility required when a worker moves along a transmission line. Generally, high-voltage power produced at power plants can be supplied to consumers via transformer facilities, which is possible because transmission lines are installed between the power plant and the transformer facilities. Accordingly, regular inspections of transmission lines are an essential task for a stable power supply. Conventionally, inspection work on transmission lines is carried out by installing spacer cars or movable ring ropes on the transmission lines and then having a worker move directly along the transmission lines using the spacer cars or movable ring ropes. During this process, the worker moves by holding the power line with their bare hands while the power line is tucked under their armpit, which causes the worker's clothing to be damaged due to continuous friction with the power line. Furthermore, during power transmission line inspection work, workers' hands are not only contaminated by gripping the lines, but as the work continues, the palms also experience discomfort due to friction with the lines. FIG. 1 is a perspective view illustrating the usage state of an auxiliary facility for moving a transmission line according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of FIG. 1 showing an auxiliary facility for moving a transmission line according to an embodiment of the present invention mounted on a transmission line. FIG. 3 is an enlarged drawing of an idler roller constituting a movement guide in an auxiliary facility for moving a transmission line according to an embodiment of the present invention. FIG. 4 is a partial enlarged view for explaining the configuration of a braking induction unit in an auxiliary facility for moving a transmission line according to an embodiment of the present invention. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached illustrative drawings. In this process, the thickness of lines or the size of components depicted in the drawings may be exaggerated for clarity and convenience of explanation. Furthermore, the terms described below are defined considering their functions in the present invention, and these may vary depending on the intention or convention of the user or operator. Therefore, the definitions of these terms should be based on the content throughout this specification. In addition, the following embodiments are not intended to limit the scope of the present invention but are merely exemplary details of the components presented in the claims of the present invention; any embodiments that include components that are included in the technical concept throughout the specification of the present invention and are substitutable as equivalents for the components of the claims may be included within the scope of the present invention. Referring to the drawings, the auxiliary equipment for moving a transmission line according to an embodiment of the present invention comprises a cover part (10), a movement guide part (20), and a braking guide part (30). The above cover portion (10) is installed in a manner that covers the outer surface of the transmission line (40), and corresponds to the part that is grasped by the worker when the worker moves along the transmission line (40). At this time, the transmission line (40) may be an example of a multi-conductor type cable such as a bundled conductor or a four-conductor cable. To this end, the cover portion (10) is configured to have an outer skin portion (11) that is in close contact with the outer surface of the transmission line (40) as shown in FIGS. 1 and 2, and a housing portion (12) that protrudes outward from the outer skin portion (11) and installs the moving guide portion (20). In this case, the outer surface of the outer skin (11) may be composed of a flexible fiber material that ensures flexibility for proper contact with the outer surface of the transmission line (40), and the inner surface of the outer skin (11) may be composed of a rubber material that ensures flexibility while guaranteeing proper sliding against the outer surface of the transmission line (40). At this time, the different materials constituting the outer skin (11) may be integrated with one another through coating or bonding. In addition, it is preferable that the housing part (12) be composed of a rigid material having appropriate strength for installation and support of the moving guide part (20). For example, the housing part (12) may be composed of a plastic material product that ensures rigidity. The above-mentioned movement guide (20) is a member installed on the cover (10) that makes rolling contact with the outer
