Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention is a cable tip guide vehicle used when laying a cable on a high place in a cave, that is, on a ladder provided on the side wall of the cave. Pertain to.

(Conventional technology) In order to extend an ultra-high voltage cable in a cave, a cable feeding device that clamps the cable between a pair of vertically opposed endless electric running zones and feeds the cables by the running zones is used. I use it and try to pull it into the cave.

When pulling in the cable, it was often necessary for an operator to hold and guide the tip of the fed cable by hand.

However, as shown in FIGS. 2A and 2B, when laying an ultra-high voltage cable on the floor surface 2 of the cavern 1, a plurality of cable feeding devices 3 are installed along the cable laying path to the central upright 4.
It is attached to the pedestal 5 that is fixed to the pedestal and fixed to the floor of the cave, and the tip of the cable 6 is fixed to the tip guide vehicle 7 that travels along with the delivery of the cable, so that holding and guidance by hand are unnecessary. The tip guide wheel 7 has a structure capable of straddling the cable delivery device 3 so that the cable delivery apparatus 3 does not hinder the travel of the tip guide vehicle 7. Also, when laying on the lowermost one of the ladders 8 provided on the side wall of the tunnel shown in FIG. 2A, the cable may be transferred to the lowermost ladder after being extended as described above. . In addition, 9 in FIG. 2B indicates a flat roller provided in the middle of the cable feeding device and receiving a cable load.

(Problems to be solved by the invention) However, since the cables are laid in the middle and top ladders, the cable sending device must be installed at a high place in order to extend the wire to a high place in the cave. It was difficult to make the tip guide vehicle straddle the cable delivery device, and it was necessary to raise the cable to the required height after the wire was once extended to the cave floor. Thus, it was difficult to manually transfer the wire to the ladder at a high place after the wire was extended to the floor of the cave as described above. Therefore, in order to extend and lay a conventional cable in a high place inside a cave, use a lift truck that has a slope that extends from the floor of the cave to the required height and a cable sending device in the middle of this slope. The cable extended to the floor of the cave was raised to the required height.

In the above-mentioned conventional cable extension and laying means for a high place in a cave, there is a drawback that the work efficiency is low because it requires two steps of extending the cave floor and raising it to a high place.

The present invention has been made based on the above circumstances, and an object thereof is to provide a cable tip guide vehicle that can be directly extended to a high place without once extending to the floor of a cave.

(Means for Solving the Problems) A cable tip guide wheel of the present invention is a vehicle body having a rectangular planar shape and casters at each corner of the bottom surface, and the vehicle body that is erected at the center of one long side of the upper surface of the vehicle body. Of the cable end support member having an inverted L-shape having a vertical part parallel to the vertical edge of the cable and a horizontal part projecting toward the other long side, and a cable end provided at the tip of the cable end support member. It is characterized by having a cable tip gripping portion for suspending and supporting, and a guide roller which is provided at one corner of the bottom surface and cooperates with a guide groove excavated in the bottom of the cave.

(Operation) In the cable tip guide vehicle of the present invention having the above configuration, the cable tip is suspended and supported on the tip of the cable support member, so that the cable tip guide is provided even when the cable sending device is installed at a high place in the cave. There is no interference between the car and the cable delivery device.

(Embodiment) FIG. 1A is a schematic plan view of one embodiment of the present invention, FIG. 1B is a front view thereof, and FIG. 1 with the same parts as those in FIG. 2A and FIG. C is a side view thereof. In these drawings, a vehicle body 10 is formed in a frame structure by connecting four pipe members 11a to 11d, which are respectively positioned at the apexes of a rectangle and arranged in parallel, by connecting members 12a to 12d. Thus, the casters 13a are provided at the lower ends of the four pipe members 11a to 11d.
~ 13d are attached respectively. Also, from the bottom 3
An inverted L-shaped cable tip support member 14 is planted and fixed at the center position of the interval between the pipe members 11a and 11b of the connecting member 12c at the step with its long sides parallel to the pipe members 11a to 11d. ing. The long side is fixed and supported at the center of the uppermost connecting member 12d.

Further, a cable tip grip portion 15 is provided at the tip of the cable support member 14. One of the pipe members 11a to 11d, which is on the side of the cable supporting member 14 parallel to the pipe member, such as the lower end of the pipe member 11b, is located in the floor surface 2 of the cavern in the longitudinal direction of the cavern. A guide roller 17 that engages with the excavated guide groove 16 is attached.

The cable tip guide wheel of the present invention having the above structure operates as follows. That is, the tip of the cable 18 sent by the cable sending device 3 on the pedestal 5 fixed at a high position of the central upright 4 is gripped by the cable tip grip portion 15 to drive the cable sending device 3. Then, the cable 18 is sent out in the direction of arrow A in the drawing, and the cable tip guide wheel is also driven in the same direction as the cable 18 is sent out. Thus, the cable tip guide wheels are casters 13a-13d.
Is in contact with the cave floor 2 by the pipe member 11b
Since the guide roller 17 provided at the lower end of the cable is engaged with the guide groove 16 excavated in the floor surface 2 of the cave, the cable guide vehicle of the present invention can travel according to the shape of the extension line or the laying route. Become.

In the cable tip guide wheel of the present invention having the above configuration, the tip of the cable 18 is suspended and supported on the tip of the cable support member 14, so that the cable tip guide wheel and the cable sending device 3 do not interfere with each other. In addition, the load of the cable 18
Since it acts on the center of the cable 10, the cable tip guide wheel can travel stably.

The present invention is not limited to the above embodiment. For example, the vehicle body 10 can be made of a bar material, a plate material, or any other suitable material. Further, the height of the tip of the cable tip support member 14 may be adjusted so that the cable can be extended or laid at a desired height in the cave.

[Effect of the Invention] As is apparent from the above, in the cable tip guide vehicle of the present invention, the cable can be directly extended or laid in a high place in the cave, so that the conventional double extension or laying is required. In comparison with the above, the work of drawing or laying work can be significantly saved.
