Description

Cable guide structure and device for cable laying of cable tray {Cable guide and apparatus for laying cable in cable tray}

The present invention relates to a cable guide structure and a device used when laying a cable in a cable tray, and more specifically, to prevent damage to a cable to be laid by default, and to install a cable without fear of damage to the cable tray itself It relates to a cable guide structure and its apparatus.

In general, in a factory or a large building, a number of cables for supplying power to the interior are installed along the ceiling, floor or wall. At this time, the cable is guided by the cable tray and installed.

In the cable laying operation using the cable tray, the cable tray is first installed along the section where the cable is to be placed, and then the cable is installed by pulling the cable along the installed cable tray. Therefore, in the case of laying the cable, friction may occur between the cable tray and the cable when the cable is excessively pulled, which may cause a cable damage or a cable tray damage.

In order to solve this problem, by installing a roller in the section where the cable is pulled along the cable tray to reduce friction with the cable, it was intended to improve cable damage and cable tray breakage.

As a typical example, Korean Utility Model Registration No. 20-0395617 (registered on September 5, 2005, the name of the design "Cable Tray") proposed a cable tray comprising a roller frame equipped with a plurality of rollers on a support frame on which a cable is seated. .

As another example, in the Republic of Korea Patent Registration No. 10-0829726 (2008.05.08 registered, the name of the invention "cable tray") in the cable tray consisting of a support frame and a side frame, installed on the support frame or side frame to guide the cable We proposed a cable tray that can improve durability by improving the assembly structure of the roller.

However, the cable tray presented in the above-mentioned utility model registration and patent registration documents can be considered to have improved to some extent in terms of reducing the frictional contact of the cable, so the roller is integrally installed with the cable, so it is necessary to position the roller at the work site. It is not only easy to change, but also causes a cost increase due to the installation of multiple rollers. Moreover, in the cable tray curved section, frictional contact between its side and the cable is still a problem.

Various attempts have been made to improve these problems, and as a representative example of this, in Korean Patent Registration No. 10-1122272 (registered on February 23, 2012, the name of the invention, "auxiliary device for cable laying"), it is easy to carry due to its small volume and weight An auxiliary device for laying a cable was proposed.

However, the cable laying auxiliary device proposed in Korean Patent Registration No. 10-1122272 has a structure that is fixed up and down on the side of the cable tray, so it is practically close to the cable tray in the part supported by the roller. There is a disadvantage in that the transfer section is limited to the side, and since the contact between the cable and the roller to be installed is made arbitrarily, there is a structural limitation in which the ease of the operator is determined according to the contact situation of the towed cable and the roller.

Republic of Korea Utility Model Registration No. 20-0395617 (Registered on Sep. 2005, Design title "Cable Tray") Republic of Korea Patent Registration No. 10-0829726 (2008.05.08 registered, the name of the invention "cable tray") Republic of Korea Patent Registration No. 10-1122272 (2012.02.23.
