The moving carriage 300 includes a body 301 configured to be movable along the guide rail 200 and a plurality of moving bodies 300 disposed on the body 301 and rotating along the guide rail 200. [ Rollers. Referring to FIGS. 6 to 9, the following will be described.

Fig. 6 is a perspective view showing a state in which the moving rail is fastened to the guide rail, Fig. 7 is a rear perspective view showing the moving railroad, Fig. 8 is a side view showing the moving railroad, and Fig.

The moving carriage 300 includes a main body 301 to which the support belt 700 is connected and supported in a lower direction of the lower flange 210 of the guide rail 200 so as to be rotatable on the lower flange 210 A main roller 310 coupled to the main body 301, a first auxiliary roller 320 coupled to the main body 301 to rotate while contacting the side surface of the lower flange 210, And a second auxiliary roller 330 coupled to the main body 301 so as to rotate while contacting the lower surface of the main body 301.

The main roller 310 may be made of at least two rollers so as to contact each of the two upper surfaces of the lower flange 210 separated by the wave 230. When the driving unit 500 pulls the connecting wire 20, the main roller 310 rotates on the upper surface of the lower flange 210 and the moving carriage 300 moves along the guide rail 200 Can be moved.

The first sub-rollers 320 may be disposed on both sides of the lower flange 210. For example, as shown in FIGS. 6 to 9, the first auxiliary roller 320 may be provided on the left and right sides of the body 301, and four on the left and right sides. The first auxiliary roller 320 rotates while contacting both sides of the lower flange 210 and the rotation axis of the first auxiliary roller 320 may be parallel to the wave 230 of the guide rail 200 have. The first auxiliary roller 320 is disposed on the front and rear sides of the body portion 301 so as to be in contact with both side surfaces of the guide rail 200. Accordingly, when the moving rail 300 moves along the guide rail 200, It is possible to prevent the guide rail 300 from deviating to the left and right of the guide rail 200. Further, when the guide rail 200 has a curved portion from the left to the right, friction between the guide rail 200 and the moving carriage 300 can be reduced.

The second auxiliary roller 330 may be disposed between the lower surface of the lower flange 210 and the body 301. For example, as shown in FIGS. 7 to 9, the second auxiliary roller 330 may be provided on the left and right sides of the body 301, and four on the left and right sides. The second auxiliary roller 330 rotates while being in contact with the lower surface of the lower flange 210. The rotation axis of the second auxiliary roller 330 is connected to the lower surface of the lower flange 210 of the guide rail 200 . ≪ / RTI > The second auxiliary roller 330 is disposed on the front and rear sides of the body 301 and contacts the lower surface of the lower flange 210 of the guide rail 200. Therefore, The bogie 300 moves according to the bending to prevent direct collision with the lower flange 210 even if the body 301 rises. Therefore, when the guide rail 200 has a curved portion in the vertical direction, friction between the guide rail 200 and the moving carriage 300 can be reduced.

Meanwhile, the moving truck 300 may include a support belt 700 for supporting the cable 10. The support belt 700 may be provided to extend downwardly from the body portion 301 and may be made of a suitable material having appropriate strength and flexibility so that the cable 10 can be supported by the support belt 700 have.

When the cable 10 moves together with the movement of the moving carriage 300 and a slip occurs between the cable 10 and the support belt 700, Only the moving bobbin 300 moves without moving. Therefore, in order to prevent such a slip phenomenon, a friction member (not shown) may be provided on the inner side of the support belt 700 to prevent the cable 10 from slipping. The friction member maximizes the frictional force between the cable (10) and the support belt (700), thereby preventing the slip phenomenon and minimizing the power loss.

The height of the cable 10 supported by the support belt 700 may be determined so as to correspond to the height of the hanger 410 installed on the guide support 400. The height of the cable 10 supported by the support belt 700 may be greater than the height of the hanger 410 when the cable 10 is moved to the hanger 410. [ It is very cumbersome and troublesome when the cable 10 is seated on the hanger 410. Therefore, in order to solve the inconvenience of the operation, the deflection length of the support belt 700 supporting the cable 10 is determined by the height of the cable 10 supported by the support belt 700, 410). When the height of the cable 10 supported by the support belt 700 corresponds to the height of the hanger 410 as described above, when the cable 10 is placed on the hanger 410 to be laid It can be installed very easily.

In order to adjust the height of the cable as described above, the support belt may have a length adjusting unit (not shown). That is, when a plurality of hanger is formed on the guide supporter so as to lay a plurality of cables, the length of the support belt is adjusted by using the length adjuster to adjust the cable height according to the height of each of the plurality of hanger The cable can then be moved.

Further, the cable laying apparatus of the present invention is formed with the guide rails so as to correspond to the positions of the hanger on which the cables are mounted. Since the guide rail is formed on a substantially straight line above the hanger, the cable conveyed by the moving rail provided on the guide rail can be easily placed on the hanger. In other words, unlike the conventional caterpillar laying method or battery car laying method in which a cable is transported at the center of a power section, the cable laying apparatus of the present invention finally transfers the cable along the position where the cable is installed, It can be separated from the support belt and easily put on the hanger on the lower side.

However, the cable conveyed along the guide rails moves adjacent to the wall of the guide support or the power port. In this case, there is a possibility that the cable may be damaged by collision with a wall surface of the guide support or the power port during movement. Therefore, the cable laying apparatus of the present invention further includes a cable guide roller 430, which prevents the cable from moving in the left to right direction during movement, thereby preventing damage to the cable.

In addition, the cable laying apparatus may include a connecting wire guide roller 420. The wire guide roller 420 can prevent the cable connecting wire from sagging.

The cable installation apparatus according to an embodiment of the present invention may further include the moving vehicle monitoring unit of FIG. Since the cable is seated on the plurality of support belts, it is possible to minimize the occurrence of cable bending between the support belts by keeping the distance between the plurality of support belts constant, By monitoring the moving distance, the operator can set the moving carriage at a fixed distance to seat the cable on the supporting belt. The mobile tracking unit may include a first monitoring device and a second monitoring device. When the cable is laid by using the cable laying apparatus of the present invention, the operator is located at a position where the cable feeding is started, and places the cable on the supporting belt of the moving car. In this case, the first monitoring device may generate a signal to induce a preparation operation for seating the cable on the support belt, and the second monitoring device may generate a signal to guide the operation of seating the cable on the support belt have. Specifically, the first and second monitoring devices can monitor the moving distance of the moving vehicle by generating a signal or the like when a predetermined time elapses from the moving time after checking the moving time of the moving vehicle moved ahead, The signal may be an acoustic signal or the like.

The cable installation apparatus according to the present invention may further comprise the tension monitoring apparatus of FIG. The tension monitoring device may include a load cell to monitor the tension acting on the connecting wire when the cable is moved, thereby confirming the operating state of the cable laying apparatus.

While the present invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims. .
