In the case of a newly installed train line, a decelerator (a mechanism for pulling the cable) is disposed every 1 to 2 km, After connecting the cable with a wire (also called a "wire" and having a thickness of about 5 mm), pull the pulling line connected to the reducer by operating the reducer to pull the cable by mechanical force. In this case, when the cable is pulled by the reducer, a strong mechanical force is applied, so that the cable is damaged or the cable which is already laid is damaged. In addition, the load applied to the reducer is increased due to the heavy weight, There is a problem that a failure of the speed reducer frequently occurs.

On the other hand, when additional cables are installed on the existing line, the operator places the cable at the tip of the cable and pulls it by hand to lay it in a manual manner. Therefore, friction between the cable and the cable or friction between the already- There is a problem that the work force of the worker is very high and a lot of manpower is pulled together and there is a concern of safety accident at all times.

In addition, in the conventional installation method used in the field until now, regardless of whether it is installed by a reducer or by manpower, there is a serious friction between the installed cable and the already installed cable, There is a problem that the indication of the division of the ownership of the cable and the distance indication is erased.

In order to solve the above problems, a technology such as patent registration No. 1307324 entitled " Movable 3-column power cable simultaneous laying apparatus for a new railway roadbed "and patent registration No. 1361065" Moving type 3-column power cable simultaneous laying method for a new railway roadbed & However, the structure of the device itself is complicated, and a support vehicle for capturing the cables is required. In many cases, the traps buried in the existing train line are installed in a terrain where the vehicle is difficult to move, There is a problem that there are many sections that can not be done.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an air conditioner having a roller installed in a sidewall, The present invention is to provide a cable cable laying apparatus capable of easily and conveniently laying a cable with a small work force by minimizing the friction between the cable installed on the bottom of the trough and the cable laid on the seating groove of the trough .

In order to solve the above-mentioned problems, the trough cable slinger according to the present invention has a 'C' shape in which a cross section is opened downward, and both side walls of the trough are inserted into the open portion, A pair of mounting portions; A rubber pad which is positioned between the inner side surface of each of the mounting portions and both side walls of the trough so as to prevent the mounting portion from sliding on the side wall of the trough during the pulling of the cable; And a bobbin-shaped roller mounted on a rotating shaft connected between the pair of mounting portions.

Preferably, the roller is structured such that a bearing is mounted between the roller and the rotary shaft to rotate smoothly, and a roller is formed with a seating groove on which the cable is seated.

Preferably, the roller is constituted by installing two rollers between a pair of mounting portions.

Preferably, the height of the upper end of the mounting portion is higher than the height of the upper end of the roller, so that the cable is prevented from being detached from the trough during the laying operation.

The trough cable crawler according to the present invention having the above characteristics is mounted on both side walls of the trough and is mounted at regular intervals along the longitudinal direction of the trough, in which a roller rotated by a bearing is mounted between both side walls, Since the installed cable is installed through the seating groove formed on the roller, there is no friction between the installed cable and the bottom of the tread or the cable installed, and it is remarkably reduced so that the cable can be easily and conveniently installed can do.
