JPH0683979B2 - Cover for live-line work manipulator - Google Patents

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover cover used by being attached to a manipulator for performing live-wiring work on a covered electric wire such as a high voltage overhead power distribution line.

(Prior Art) Recently, manipulators are being used for various live-wiring operations for covered electric wires such as high-voltage overhead distribution lines.

In such live-line work, when a down line is branched from a distribution line via a V-type connector or the like, a cover made of synthetic resin or the like is used to enhance the waterproof property of the branch portion. The work of covering the cover is done by a worker manually attaching it to the electric wire at a high place.

(Problems to be solved by the invention) Since such a cover work is carried out by a worker at a high place with a cover or a tool, the worker is physically tired and is mentally tense against an electric shock or a fall accident. This is a heavy work.

The present invention has been made based on such a background, and proposes a cover cover that can be attached to a manipulator to cover the cover, thereby reducing the burden on the operator involved in the manual work. The purpose is to do.

(Means for Solving the Problems) Therefore, according to the present invention, a live wire is attached to a manipulator at the time of hot-wiring work on the distribution line, and the distribution line is covered with an adhesive-filled inside. A cover cover for a wire work manipulator, one end of which is pivotally supported and is arranged so as to be able to come into contact with and separate from each other and is always V
A cover holder that includes two plates that are open in a V shape, holds a cover between the facing surfaces of the open plates, and is sandwiched from the outside to the other end of each plate,
The manipulator has a sandwiching device that brings the two plates close to each other by the rotational driving force of the manipulator.

(Operation) Therefore, by driving the sandwiching device, the cover holder having the cover between the surfaces of the plates is closed, and the work of covering the electric wire with the cover can be performed as a remote work without requiring manual work. Since the cover can be put on, the operator's physical fatigue and the mental tension against an electric shock or a fall accident are eliminated, and the burden on the operator is reduced.

Further, since the plate of the cover holder is always opened in a V shape and the clamping device is clamped between the two plates from the outside, the cover for the distribution line can be held between the opposing surfaces of the plates. .

In this state, when a rotational driving force is applied to the sandwiching device from the manipulator, the sandwiching device pushes the other ends of the two plates to bring the two V-shaped open plates close to each other. Therefore, when a rotational driving force is applied from the manipulator, the sandwiching device pushes the other ends of the two plates pivotally supported at one end so that they can be separated from each other, so that a strong pressing force can be generated. Furthermore, depending on the rotational driving force of the manipulator, 2
Since the plates come close to each other, the clamping device can generate a strong pressing force by increasing the rotation driving time.

As a result, the cover filled with the adhesive can be held inside the plate at the time of hot-wiring work, and the held cover can be reliably covered with the distribution line.

(Embodiment) Hereinafter, the embodiment shown in the drawings will be described. Prior to this, a cover for covering an electric wire by a cover cover described below will be briefly described with reference to FIGS. 6 and 7.

In FIG. 6, A is a distribution line, B is a down line, and a branch portion D of the down line B from the distribution line A through the V-type connector C.
Is configured.

Then, a cover E that covers the branch portion D including the V-shaped connector C
Are mounted as shown in FIG.

The cover E is composed of a cover body F formed by bulging a soft synthetic resin sheet, a sponge G arranged in the cover body F, and a filled adhesive H.

The cover E has an integral shape in which the left and right halves of the O-O line are connected at the upper part, and the lower part of the cover E is separated along the O-O line before the cover E is used. In this state (see the phantom line in FIG. 1), the adhesive between them is adhered to each other by being pressed against each other by being attached to an electric wire or the like, and the branched portion D is waterproofed. It enhances.

The cover cover of the first embodiment will be described below with reference to FIGS. 1 to 3.

In FIG. 1, reference numeral 1 is a cover cover, and the cover cover 1 has a frame 2 provided with a cover holder (hereinafter, simply referred to as a holder) 3 and a sandwiching device 4, and drives the respective first and second cover holders. It has drive systems 5 and 6.

The holder 3 includes two holder plates arranged facing each other.
11 and 12 are configured as a set, and one end, that is, the upper part of these holder plates 11 and 12 is a mounting pin 13 which also serves as a pivot.
The holder plates 11 and 12 are configured to be openable and closable with the other end, that is, the lower part, as a swing end, and the inner surfaces of both plates 11 and 12 can be contacted and separated.

As described above, the reason why the plates 11 and 12 can be brought into contact with and separated from each other via the pivot is to ensure that the plates 11 and 12 can collide with each other with a simple structure.

A pressing member 14 is fixed to the inside of the holder plates 11 and 12 to ensure adhesion when the cover E set between the holder plates 11 and 12 is sandwiched. Is.

Further, hooks 15 are installed at the lower ends of the holder plates 11 and 12 so as to project inward from the inner surfaces of the holder plates 11 and 12, and the lower edges of the cover E are locked to the hooks 15 by locking them. The cover E is set on the holder 3. The hook 15 has a structure in which, when the cover E is clamped, the hook 15 is detached from the cover E at the same time.

In this embodiment, a coil spring 16 is provided around the mounting pin 13, and both ends of the coil spring 16 are locked to the pins 16a planted on the side surfaces of the holder plates 11 and 12, thereby The holder plates 11 and 12 have open habit.

This is the holder 3 by the pinching device 4 in this embodiment.
This is to simplify the structure of the pinching device 4 by driving only in the pinching direction as described later.

In this embodiment, the set of holder plates 11 and 12 having such a structure are spaced apart from each other so that they can be installed on both sides of a base plate 17 that is driven up and down by a first drive system 5, which will be described later. Corresponding holder plates of the set of plates 11 and 12 are connected to each other by a connecting shaft 18 and a connecting member 19 so as to integrally swing so that the holder 3
Is configured.

The holder 3 configured in this manner is detachably attached from both sides with screws or the like via the respective attachment pins 13 of the set of holder plates 11 and 12 arranged on both sides of the base plate 17.

In this way, the holder 3 itself is not provided with a device for driving the holder 3 to close it, and the holder 3 is closed by the sandwiching device 4 described later, and the holder 3 is attached to the base plate 17 only by the mounting pins 13. The detachable structure is used because the holder 3 can be replaced so that the cover E of the various sizes and shapes can also be covered with the cover E, so that the holder 3 can be easily replaced. This is because

In the figure, reference numeral 17a is a stopper to prevent the holder 3 from being excessively opened by the coil spring 16.

The connecting shaft 18 serves as a portion for receiving a force from the pinching device 4, which will be described later, and the connecting member 19 firmly presses the lower edge of the cover E when the cover E is pinched to complete the bonding. It is also a part that has the function of promoting

Next, the first drive system 5 for vertically moving the base plate 17 having the holder 3 will be mainly described with reference to FIG.

That is, in the first drive system 5, via the first drive shaft 22 in the drive connecting portion 21 that is provided on the lower surface of the cover cover 1,
The rotational drive force of the tip drive unit (not shown) of the hot-line work manipulator is supplied.

When the first drive shaft 22 is rotationally driven, the sprocket 23 and the chain 24, which are coaxially installed, drive the driven sprocket.
25 is driven, the worm shaft 26 to which the driven sprocket 25 is fixed rotates, and the coaxial worm 27 rotates.

The rotation of the worm 27 causes the wheel 28 meshing with the worm 27 to rotate, whereby the arm 30 fixed to the wheel shaft 29 swings as shown by an arrow a in FIG.
The base plate 17, which is fixed to the tip of 30, performs a lifting operation.

Therefore, with the base plate 17 set in advance to the raised position (state of the phantom line in FIG. 3), the cover E is placed inside the holder 3.
Between the cover E set inside the holder 3 by driving the first drive system 5 after the cover cover 1 is exposed to a desired position such as an electric wire by operating the manipulator. The distribution line A and the down line B can be positioned at the position (hereinafter, this position is referred to as the lowered position).

When the manipulator is operated to position the cover cover 1 at a predetermined position on the electric wire, the mounting and positioning work of the cover E can be facilitated by using a guide fitting or the like.

Next, the sandwiching device 4 will be described with reference to FIGS. 1 and 2.

That is, the sandwiching device 4 has a screw shaft 31 supported by the frame 2 in a direction orthogonal to the electric wire, and two sandwiching pieces 32a and 32b screwed to the screw shaft 31.

A bevel gear 34 is fixed to one end of the screw shaft 31, and passes through a second drive shaft 36 in a drive connecting portion 35 projecting from the lower surface of the cover cover 1 to the first drive system 5. Similarly, the driving force is supplied from the manipulator, and the second driving system 6 is configured.

Then, the rotation of the second drive shaft 36 causes the bevel gears 37 and 34 to rotate.
Is transmitted as rotation to the screw shaft 31 via.

The screw shaft 31 includes a first screw portion 31a and a second screw portion 31b.
Are formed, and these screw portions 31a, b are formed as screws in mutually opposite directions, and the sandwiching pieces 32a, 32b are screwed to the screw portions 31a, 31b, respectively.

Rollers 38 are respectively installed on both sides of the sandwiching pieces 32a, 32b, and the upper edge of the side wall 41 of the frame 2 is used as a rail 42 to facilitate the forward and backward movement of the sandwiching pieces 32a, 32b. .

Then, when the screw shaft 31 rotates, both the sandwiching pieces 32a, 32
Since the screw directions of b are different, both sandwiching pieces 32a and 32b simultaneously perform an approaching operation or a separating operation.

When the holder 3 is in the lowered position, the first
As is clear from the figure, since the connecting shaft 18 is located lower than the upper ends of the sandwiching pieces 32a, 32b, the sandwiching pieces 32a, 32b are driven closer to each other from the outside of the connecting shafts 18. By sandwiching the holder 3 in this way, both halves of the cover E set in the holder 3 can be adhered and covered with an electric wire or the like.

Then, after the covering work is completed, the second drive shaft 36 is reversed to drive the sandwiching pieces 32a, 32b in the separating direction. In this embodiment, the habit of returning by the coil spring 16 installed in the holder 3 is improved. Therefore, the holder 3 is opened downward.

After that, if the first drive system 5 is operated to bring the holder 3 to the raised position, the cover cover 1 can be detached from the electric wire.

Incidentally, in this embodiment, by the coil spring 16,
Although the holder 3 is opened, if the holder plate is connected to the sandwiching pieces 32a, 32b, the holder 3 can be opened by the separating operation of the sandwiching pieces 32a, 32b.

Needless to say, the same function can be achieved by adopting a known advancing / retreating means instead of the screw shaft 31 in the construction of the clamping device 4.

In this way, by configuring the cover cover 1,
Since the cover covering device 1 can be attached to an existing hot-wire work manipulator to cover the electric wire or the like with the cover E as a remote work, the mental and physical burden on the worker is reduced.

Next, a second embodiment will be described with reference to FIGS. 4 and 5, but this embodiment has a lot of common points although there are differences from the previously described first embodiment, and therefore the following description is different. Regarding the common points, the same reference numerals as those in the first embodiment are given to the drawings and the description thereof is omitted.

First, in this embodiment, the first
No corresponding drive system 5 is provided, the cover cover 45 has a frame 46, a holder 47, and a clamping device 48, and the arrangement of the holder 47 and the clamping device 48 with respect to the frame 46, etc. This is different from the first embodiment.

The frame 46 is formed in a box shape that is opened generally downward, and a drive connecting portion 51 is installed on the upper surface of the frame 46, and a rotary drive force supplied from the manipulator is used to drive the drive shaft 52 and a bevel gear. The screw shaft 55 is rotationally driven, and the sandwiching pieces 56a and 56b have the same construction as the second drive system 6 of the first embodiment so that the sandwiching pieces 56a and 56b perform the approaching or separating operation by the rotation of the screw shaft 55. There is.

Then, on both outer sides of the side wall 41 of the frame 46, which is lateral to the central portion of the screw shaft 55, holders 47 are installed downwardly opened via mounting pins 57. The sections 12 are connected by a connecting shaft 18 and a connecting member 19, respectively.

And, the sandwiching pieces 56a, 56b are formed in a form projecting downward, and since the lower ends of these sandwiching pieces 56a, 56b are located below the connecting shaft 18, the sandwiching pieces 56a, 56b are formed. The holder can be closed by moving 56b in close proximity.

In this embodiment, as described above, the frame 46
Has a downward opening shape, and the sandwiching pieces 56a, 56b have a shape hanging from the screw shaft 55, so that the rail 42 on which the roller 38 rolls is formed at the lower edge of the side wall 41.

In the second embodiment constructed in this manner, as in the first embodiment, the cover E is set inside the holder 47, the screw shaft 55 is rotated, and the sandwiching pieces 56a and 56b are driven close to each other. As in the first embodiment, the cover E can be covered with an electric wire or the like, and the cover cover 45 can be removed from the electric wire or the like by reversing the drive shaft 52.

As described above, this embodiment has the advantages that the cover cover is light in weight and the load applied to the manipulator is small as compared with the first embodiment described above because the structure is simple.

(Effect of the Invention) Since the present invention is configured as described above, by driving the sandwiching device with the manipulator, the cover holder having the cover between the surfaces of the plates is closed, and the live wire is covered with the cover. Since the work can be performed as a remote work and the cover can be covered without requiring manual work, the operator's physical fatigue and mental tension against an electric shock or a fall accident are eliminated, and the burden on the operator is reduced. .

Further, since the plate of the cover holder is always opened in a V shape and the clamping device is clamped between the two plates from the outside, the cover for the distribution line can be held between the opposing surfaces of the plates. .

In this state, when the manipulator applies a rotational driving force to the sandwiching device, the sandwiching device pushes the other ends of the two plates, and V
The two plates that are open in a letter shape are brought close to each other. Therefore, when the manipulator applies a rotational driving force, the sandwiching device pushes the other ends of the two plates pivotally supported so that one end thereof can come into contact with and separate from the other, so that a strong pressure can be generated. Further, since the two plates approach each other in accordance with the rotational driving force of the manipulator, if the rotational driving time is lengthened, the sandwiching device can generate a strong pressing force.

As a result, the cover filled with the adhesive can be held inside the plate at the time of hot-wiring work, and the held cover can be reliably covered with the distribution line.
