Description

Description: TECHNICAL FIELD The present invention relates to a wire turbulence prevention device for a temporary electric wire work vehicle used when constructing an electric wire such as a transmission line stretched over a utility pole.

(Prior Art) Generally, on the chassis of an electric wire temporary work vehicle, an electric wire drum around which a temporary electric wire is wound, a pilot rope drum around which a pilot rope for feeding the temporary electric wire is wound, and a temporary electric wire are lifted. Various things such as a hanging rope drum around which a hanging rope is wound to guide it between electric poles are installed.

As shown in FIG. 6, the suspension rope A has one end fixed to a power pole and the other end wound up by a suspension rope drum 45 and stretched below the power transmission line. The pilot rope B is a suspension rope. It is stretched below A via a pulley K.
A temporary electric wire C is connected to one end of the pilot rope B,
The temporary electric wire C and the suspension rope A are bound by a hook F.

When the pilot rope B is wound up by the pilot rope drum 9, the temporary electric wire C is guided from the electric wire drum 12 to the suspension rope A and is fed out. When the temporary electric wire C is fed to a predetermined position, both ends thereof are connected to the power transmission line D as shown in FIG. 7, power transmission is started through the temporary electric wire C, and construction of the power transmission line during this period is performed. And
After the construction is completed, the suspension rope A, the pilot rope B, and the temporary electric wire C are wound around the respective drums 45, 9, 12.

By the way, the temporary electric wire C must be wound around the outer circumference of the electric wire drum 12 so as not to be wound in multiple layers,
If this is wound irregularly, problems such as damage to the temporary electric wire C and stop of the drive device of the electric wire drum 12 occur.

(Problems to be Solved by the Invention) Conventionally, as a wire turbulence prevention device, a wire guide member (not shown) for hanging an electric wire is known to be horizontally moved according to a winding state. (For example, Japanese Patent Publication 58-20207
Gazette, Japanese Patent Publication No. 57-16570). In this type of device,
It is important to move the guide member horizontally in accordance with the number of rotations of the electric wire drum 12, and unless the operations of the two are synchronized, irregular winding cannot be sufficiently prevented. Japanese Patent Sho 58-202
The one described in Japanese Patent No. 07 has a problem that it is troublesome and difficult to synchronize the two because the wire guide member is manually moved. The one described in Japanese Patent Publication No. 57-16570 drives the electric wire guide member and the electric wire drum by separate driving devices, and the control circuit for synchronizing becomes complicated, which is disadvantageous in terms of cost and maintenance. is there.

Therefore, an object of the present invention is to eliminate the problems of the above-described conventional technique, and to prevent the temporary electric wire from being wound around the electric wire drum without being randomly wound. To provide.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention, as described above, according to the present invention, first, when the revolution hydraulic motor is driven at the time of feeding the temporary electric wire, The main shaft is rotated and the predetermined electric wire drum is revolved to the take-up and winding position of the temporary electric wire.
At this time, the gear of the predetermined electric wire drum is meshed with the gear of the hydraulic motor for rotation. As a result, the predetermined electric wire drum is allowed to rotate, and the temporary electric wire of the drum is paid out as the electric wire drum rotates.

Next, when the feeding of the temporary electric wire is completed and the temporary electric wire is wound up, the rotation hydraulic motor is driven. At this time, since the gears of the predetermined electric wire drum and the gears on the rotating hydraulic motor side are meshed with each other, these gears are rotated by the drive of the rotating hydraulic motor, and the predetermined electric wire drum is rotated. The temporary electric wire is wound around the electric wire drum.

At this time, since the hydraulic pump is driven in synchronization with the rotation hydraulic motor, the hydraulic pump supplies pressure oil corresponding to the amount of rotation of the electric wire drum to the hydraulic cylinder. The electric wire guide member is horizontally moved by the expansion and contraction operation of the hydraulic cylinder corresponding to the pressure oil.

Next, the operation of the electric wire temporary work vehicle according to the present invention will be described.

First, in order to stretch the suspension rope A between electric poles as shown in FIG. 4, the suspension rope A for extension is suspended from the extension rope drum for extension.
Pull out from 11 by hand and fix the tip to the utility pole at the end. Further, the other end of the suspension rope A for extension is joined to the tip of the suspension rope A wound around the suspension rope drum 45. Then, the suspension rope drum 45 is driven to start winding the suspension rope A. If the suspension rope A is stretched at a predetermined position (the position shown in FIG. 6) and the suspension rope is slack, the telescopic cylinder 52 is contracted to increase the tension to suspend the suspension rope A. The slack of the rope can be removed.

Prior to the joint between the temporary electric wire C and the pilot rope B, the electric wire drum 12 is moved to the above-mentioned temporary electric wire take-out position. When the revolution hydraulic motor 26 is driven, the main shaft 16 rotates via the chain 29, and each electric wire drum 12 revolves around its axis. When the electric wire drum 12 around which the necessary temporary electric wire C is wound reaches the take-out position, the drive of the revolution hydraulic motor 26 is stopped, and the gear 22 and the intermediate gear of the electric wire drum 12 are stopped.
30 is meshed with the electric wire drum 12, and the electric wire drum 12 is allowed to rotate.

After that, the hydraulic motor 8 is driven, the pilot rope drum 9 starts winding the pilot rope B, and the temporary electric wire C is sequentially fed out by being guided by the pilot rope B. The temporary electric wire C is bound to the suspension rope A via the hook F at an appropriate position. This work is done by hand. After the temporary electric wire C guided by the suspension rope A is paid out to a predetermined position, both ends of the temporary electric wire C are jointed to the power transmission line D as shown in FIG. Done.

After the construction is completed, the hydraulic motor 23 for rotation is driven to wind the temporary electric wire C around the electric wire drum 12.

Thus, according to the present invention, when the hydraulic motor 23 is driven, the hydraulic pump 36 is driven in synchronization with it, and the hydraulic cylinder 37 is expanded and contracted. Therefore, the electric wire drum
The speed of the horizontal movement of the wire guide member 100 changes according to the rotation speed of the wire 12, and the wire can be guided according to the winding state of the temporary wire C, and irregular winding can be reliably prevented. If a throttle valve (not shown) is installed on the pressure port side of the hydraulic cylinder 37 and the amount of oil can be adjusted by this throttle valve, turbulent winding can be ensured even when winding the temporary electric wires C having different wire diameters. Can be prevented.

Further, as shown in FIG. 4, a pair of micro switches 110 are arranged on the left and right on the movement path of the wire guide member 100, and when the contacts of the micro switches 110 are switched, the solenoid valve in the hydraulic circuit is changed. If the wire guide member 100 is configured to be switched (not shown), the electric wire guide member 100 can automatically repeat the reciprocating movement to improve the workability of winding.

(Effects of the Invention) Since the invention is configured as described above, according to the present invention, the speed of horizontal movement of the wire guide member is changed according to the rotation speed of the wire drum, and the electric wire according to the winding state of the temporary wire is changed. Guidance is possible and irregular winding can be reliably prevented. Moreover, since the hydraulic pump is driven by the rotation hydraulic motor that drives the electric wire drum, and the hydraulic cylinder is driven by the pressure oil from the hydraulic pump, there is no need for a complicated control circuit. It can prevent irregular winding.

Further, when a predetermined electric wire drum among the plurality of electric wire drums is revolved to the take-up and winding position of the temporary electric wire, the gear of the predetermined electric wire drum is meshed with the gear on the rotation hydraulic motor side, whereby the temporary electric wire is fed out. In addition, it is possible to wind the temporary electric wire by the hydraulic motor for rotation, so it is possible to easily replace various electric wire drums around which temporary electric wires with different diameters are wound. It is possible to easily cope with temporary electric wires of various diameters.
