DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable leading guide device which is suitable for use in laying large cables for power distribution in power plants and substations, and for laying electric circuit cables in large ships.

[0002]

2. Description of the Related Art Conventionally, as a cable laying method, for example, there has been a method described in Japanese Patent Application Laid-Open No. Sho 60-5712. In this conventional technique, a rope is laid in a closed loop on an electric path for laying a cable through a guide such as an infinite rail winch and a pulley, a rope clip is attached to an arbitrary position of the rope, and the cable clip is attached to the rope clip. A cable laying method characterized by laying a cable in an electric circuit by connecting a cable through an infinite rail winch through a cable.

[0003]

According to the above-mentioned prior art, for example, a cable is introduced from a cable drum installed on a deck near an electric circuit, and a ring-shaped connecting member called a carabiner is interposed between the cable clips and a rope clip is provided. Connect to the hole provided in. In this method, a carabiner in which a cable is fixed to a cable clip is opened, the clip and a hole of a rope clip are connected, and the carabiner is closed.

Next, in order to attach a nylon rope to the three U-shaped openings provided in the rope clip in a double S-shape, the rope is forcibly slackened against its tension, and the rope slack portion is formed. After being attached to three of the U-shaped openings of the lobe clip, the endless rail winch is driven, the rope is conveyed, the cable is pulled, and the cable is laid at a predetermined position on the electric circuit.

[0005] Then, to remove the rope clip from the rope, forcibly loosen the rope again against its tension, loosen the rope, and attach the rope clip to the rope clip at the slack portion of the rope in order to lay the next cable. If the rope is wrapped in a double S shape and attached at this position using a carabiner, the cable can be laid again with the driving force of the winch.

[0006] However, the rope in this conventional example,
Since it is necessary to attach and detach the rope clip to this rope, there is a statement that a flexible nylon rope is used, and a thin and strong steel wire rope cannot be used, and even if this wire rope is forcibly used, it is rigid The wire rope having a can not be bent and buckled in a double S-shape to the rope clip, the rope clip is easy to slip on a straight wire rope,
In addition, due to the rotation of the unwound rope that occurs on the wire rope or nylon rope due to the cable pulling rope tension, the rope clip is inherently serious in that there is a danger that the rope will stick to the rope with the cable and become unusable. There are serious problems.

If the rope has a lot of slack, the rope tends to come off from the guide pulley. On the other hand, if the rope is stretched with a little slack, the slip of the rope clip increases, and the rope clip is hardly loosened or loosened with respect to the rope. Therefore, there is a mutually inconsistent problem that a personal injury occurs in which a finger is pinched between the rope and the rope clip.

Further, apart from the above-mentioned conventional example, the one described in, for example, JP-A-7-245834 is also well known. This prior art includes a horizontal guide device disposed above a horizontal bent portion of a bent cable tray, a vertical guide device disposed above a vertical bent portion of a cable tray, and the horizontal guide device and the vertical guide device. A driving wire guided and tensioned and movable by a driving device, a cable hook fixed to a required position of the driving wire and connecting an end of a control cable, and a driving wire moved in a predetermined direction. A cable receiving roller which extends to a position for receiving the weight of the control cable when retracted, and which retreats from the position for receiving the control cable by the movement of the drive wire in the reverse direction, and is disposed at a required interval along the drive wire. And a cable supporting device.

The main point of this conventional example is to move the drive wire in the opposite direction after the cable is drawn,
The cable receiving roller is retracted from below the cable, and the cable is dropped into the cable tray to be laid. The drive wire and the cable hook drive the wire in a state where the cable hook is suspended and fixed to a plate fixed to the lower surface of the pipe called a one-touch joint. In the wire guide in the part, the structure is complicated because a large number of roller pairs need to be arranged in an arc shape, and in addition to requiring a large space, the wire must be guided by sandwiching the wire together with the cable hook with a pair of rollers,
There are many problems that the guide roller mechanism becomes more complicated and expensive.

According to the present invention, in order to eliminate the above-mentioned problems, when laying a cable in a bent cable laying path, a leading end of the cable is guided by a cable leading rope to a cable drawing machine on the laying path. By extending the cable and laying the cable, the load on the cable leading rope was reduced, the drive mechanism and the guide mechanism were simplified, and a cable hanger for connecting the cable leading end to the cable leading rope was newly developed. As a result, the cable can be quickly and reliably attached to and detached from the rope, and even if the rope is twisted due to untwisting, the cable is prevented from sticking to the rope while maintaining the rope tension to remove the wheel. It is an object of the present invention to prevent and simplify the guiding mechanism at the bent portion of the cable leading rope.

[0011]

SUMMARY OF THE INVENTION It is an object of the present invention to guide a guide pulley to a plurality of lateral arms of a plurality of posts erected along a twisted and bent cable laying path 1, respectively.

A cable guide capable of leading and guiding the cable to a cable-laying wire drawing machine installed on a cable-laying path by rotatably inserting and locking the cable so as to be rotatable and connecting the tip of the cable to a rotating piece passing through the hinge of the hanger. The device is constructed, and two pulleys of the respective guide pulleys are pivotally supported adjacent to a pulley pivotal support plate pivotally attached to the lateral arm of the post to form a pair of pulleys. The rope is laid diagonally at the hang portion to stretch the rope, and the fixing direction of the pivot plate is changed to change the slope of the skewed rope portion with respect to the length direction of the cable laying path. It could be achieved by that can be set the tension.
