12, the cable winch 100 according to the present embodiment is configured such that the width of the bobbin 300 corresponding to the length between the support plates 320 and 330 on both sides of the drum 310 of the bobbin 300 Aligning roller 180d (180c in Fig. 2) on the base frame 110 on which the one-side support plate 330 is positioned, when the one side support plate 330 is shifted from the predetermined position to the current position, As shown in FIG. When the one side support plate 330a is positioned at a predetermined position, the self-aligning roller 180d1 can be moved and installed corresponding thereto.

For such a configuration, the base frame 110 may have a structure for moving the lower support plate or the sub frame supporting the self-aligning roller 180d at regular intervals (hereinafter referred to as a moving installation structure). The movable mounting structure of the base frame 110 may include fastening holes arranged at intervals of 250 mm, for example.

In this case, the rotary center support unit 170 may be installed on the base frame 110 according to the position of the one support plate 330 of the bobbin. The base frame 110 may be fixed to the bottom surface or the bottom surface by anchor bolts 116 or the like.

13, the cable winch 100 according to the present embodiment is a cable winch 100 according to an embodiment of the present invention. The cable winch 100 according to the present embodiment is installed in an underground tunnel to extend a cable 350 via an underground structure 400, .

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as defined by the following claims It can be understood that
