Used to protect and guide cables C such as electric cables and hydraulic or pneumatic hoses, as shown in FIG. The link frame 110 includes a plurality of linked one ends in the longitudinal direction attached to a movable machine (not shown) and the other end attached to a floor (not shown). It has become.

As shown in FIGS. 1 to 3, the link frame 110 includes a pair of left and right link plates 111 and 111, and a bent body that is integrally formed horizontally on the bent inner peripheral side of the pair of left and right link plates 111 and 111. Between the inner peripheral side connecting plate 112, the bent outer peripheral side connecting plate 113 laid horizontally on the bent outer peripheral side of the pair of left and right link plates 111, 111, and between the bent inner peripheral side connecting plate 112 and the bent outer peripheral side connecting plate 113. The partition wall plate member 130 is detachably attached to the partition wall plate member 130, and the partition shelf plate member 120 is detachably attached to the partition wall plate portion seat 130 via the elastic buffer member 140.
And this partition shelf board member 120 sorts the cable accommodation space R formed by surrounding with the pair of left and right link plates 111, 111, the bent inner peripheral side connecting plate 112 and the bent outer peripheral side connecting plate 113 up and down. The partition wall plate member 130 sorts the cables housing space R into left and right.
The link frame bodies 110 are connected to each other by fitting the connecting pins 114 and the connecting pin holes 115 of the link plates 111 and 111 that are continuously arranged with each other.

Therefore, specific forms of the partition shelf plate member 120, the partition wall plate member 130, and the elastic buffer member 140, which are the most characteristic features of the cable protection guide device 100 of the present embodiment, will be described in detail with reference to FIGS.
First, as shown in FIGS. 1 to 3, the partition shelf member 120 is inserted into the shelf insertion slot 131 of the pair of partition wall plate members 130 via the elastic buffer member 140.

It is designed to prevent hitting.

  In the cable protection guide device 100 of the present embodiment obtained in this way, the partition shelf board member 120 is inserted into the shelf board insertion long hole 131 of the partition wall board member 130 via the elastic buffer member 140. In addition, since the elastic shock-absorbing member 140 is formed of a flat ring body through which the partition shelf member 120 is inserted, the elastic shock-absorbing member 140 of the partition shelf member 120 that tends to occur in the protection guide operation of the cables C is provided. In addition to preventing vibration and noise, the partition shelf board member 120 can be securely inserted and held in the partition wall board member 130, and the assembly work of the partition shelf board member 120 can be easily achieved. Even if the protective guide operation is repeated over a long period of time, the elastic buffer member 140 can be prevented from falling off the partition wall plate member 130.

  In addition, the elastic shock-absorbing member 140 includes elastic protrusions 141 that sandwich both the front and back surfaces of the partition shelf member 120, and the elastic protrusions 141 are disposed in the longitudinal direction of the cable of the elastic shock-absorbing member 140. The elastic protrusion 141 elastically deforms following the vertical movement of the partition shelf board member 120 during the protection guide operation of the cables C. Therefore, the partition shelf board member 120 is securely and stably clamped, and the partition shelf board member 120 Absorbing and reducing the offset load in the longitudinal direction of the cable with respect to the cable, reducing the local contact between the partition shelf member 120 and the cables C and avoiding damage to the cables C, etc. It is enormous.
