Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a cover cover device that is used by being attached to a manipulator that performs live wire work on covered electric wires such as high-voltage overhead power distribution lines.

(Prior Art) Recently, manipulators have been used for various live wire operations on covered electric wires such as high-voltage overhead power distribution lines.

In such live line work, when a downline is branched from a distribution line via a V-type connector, etc., a cover made of synthetic resin or the like is covered to increase the waterproofness of this branch. The work of putting the covers on the wires is done manually by workers at high places.

(Problem to be Solved by the Invention) In this type of cover-covering work, the worker carries out the work at a height while holding the cover and tools, so the worker is physically fatigued and suffers from mental stress due to electric shock and falling accidents. This is a burdensome task.

The present invention was made based on this background, and by proposing a cover covering device that can be attached to a manipulator to perform the work of covering the cover, the burden on the worker associated with the manual work is reduced. The purpose is to

(Means for Solving the Problem) Therefore, the present invention provides two
A cover holder that holds the cover between opposing surfaces of the two plates and a clamping device that clamps the cover holder from the outside of the cover holder are provided, and the clamping device is driven to close the cover holder. This is how it was done.

(Function) Therefore, by driving the clamping device, the cover holder having the cover between the surfaces of the plates is closed, and the work of putting the cover over the electric wire etc. can be performed as a remote work, without requiring manual work. Since it can be covered with a cover, the worker's physical fatigue and mental stress from electric shock and falling accidents are eliminated, and the burden on the worker is reduced.

(Embodiment) The embodiment shown in the drawings will be described below, but prior to this, a cover to be placed over an electric wire by a cover covering device to be described below will be briefly explained with reference to FIGS. 6 and 7.

In FIG. 6, A is a power distribution line, B is an underline, and v constitutes a branch of the underline B from the power distribution #lA via a connector C.

A cover E covers the branch part including the V-shaped connector C.
is attached as shown in Figure 7.

The cover E consists of a cover body F made of a bulging soft synthetic resin sheet, a sponge G disposed within the cover body F, and an adhesive H filled therein.

This cover E has an integral shape in which the left and right halves of the o-ots are connected at the upper part, and the lower part of the cover E is separated along the o-og before use. (See the imaginary line in Figure 1), and is
By pressing them against each other when attached to, etc., the adhesive between them adheres to each other, resulting in the state shown in the figure, thereby increasing the waterproofness of the branch portion.

Hereinafter, the cover fitting device of the first embodiment will be explained with reference to FIGS. 1 to 3.

In FIG. 1, 1 is a cover covering device, and the cover covering device 1 is provided with a cover holder (hereinafter simply referred to as a holder) 3 and a clamping device 4 on a frame 2. It has a drive system 5.6.

The holder 3 is constructed as a set of two holder plates 11.12 arranged facing each other, and the upper part of these holder plates 11.12 is connected to a mounting pin 13 which also serves as a pivot.
These holder plates 11 and 12 are configured to be openable and closable with their lower parts as swinging ends.
．． The inner surfaces of 12 can be moved into and out of contact with each other.

The reason why the plates 11 and 12 can be brought into contact with and separated from each other via the pivot shaft is to enable these plates 11 and 12 to reliably abut each other with a simple structure.

A pressing member 14 is fixed inside these holder plates 11 and 12, and these holder plates 1
1. This ensures adhesion when the cover E set between 1 and 12 is pinched.

Moreover, at the lower end of these holder plates 11.12,
Hooks 15 are installed to protrude inward from the inner surface of the holder plate 11.12, and by locking the lower edge of the cover E to these hooks 15, the cover E is attached to the holder
It is set to . Note that this hook 15 is
The structure is such that when the cover E is clamped, it is removed 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 pin lea implanted on the side surface of the holder plate 11.12. The holder plates 11, 12 are given an open habit.

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

In this embodiment, a set of holder plates 11 and 12 having such a configuration are spaced apart 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. The holder 3 is configured such that the 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 swing together as one.

The holder 3 configured in this way has a base plate 17
The holder plates 11 and 12 are detachably attached to each other by screws or the like from both sides via their respective attachment pins 13.

In this way, the holder 3 itself is not provided with a device that drives the holder to close, the holder 3 is closed by the clamping device 4 described later, and the holder 3 is attached to the mounting bin 13.
The reason why the cover cover device 1 is configured to be detachable from the pace plate 17 with a chisel is that by replacing the holder 3, the cover cover device 1 can also be used for the work of covering covers E of various sizes and shapes. This is to facilitate the replacement work.

In addition, 17a in the figure is an opening stopper, which prevents this holder 3 from opening excessively by the coil spring L6.

The connecting shaft 18 becomes a part that receives force from the clamping device 4 described later, and the connecting member 19 firmly presses the lower edge of the cover E when clamping the cover E to ensure complete adhesion. It is also a part that has the function of promoting

Next, the first drive system 5 that drives the base plate 17 having the holder 3 up and down will be explained mainly with reference to FIG.

That is, the first drive system 5 is connected to the tip drive section (not shown) of the live line work manipulator via the first drive shaft 22 in the drive connection section 21 protruding from the lower surface of the cover fitting 1.
rotational driving force is supplied.

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

As the worm 27 rotates, the wheel 28 that meshes with the worm 27 rotates, so that the arm 30 fixed to the wheel shaft 29 swings as shown by the arrow a in FIG. The base plate 1
7 performs a lifting operation.

Therefore, with the pace plate 17 in the raised position (as shown by the imaginary line in FIG. 3), the cover E is set inside the holder 3, and the manipulator is operated to place the cover cover device 1 on the desired position of the electric wire, etc. By driving this first drive system 5, the power distribution nA and the draw line B can be positioned between the cover E set inside the holder 3 (hereinafter, this position will be referred to as the lowered position). ).

In addition, when operating the manipulator to position the cover covering device 1 at a predetermined position on the electric wire, the work of attaching and positioning the cover E is facilitated by using a guide fitting or the like.

Next, the clamping device 4 will be explained with reference to FIGS. 1 and 2.

That is, the clamping device 4 includes a screw shaft 31 supported by the frame 2 in a direction perpendicular to the electric wire, and two clamping pieces 32a screwed onto the screw shaft 31.

32b.

A bevel gear 34 is fixed to one end of this screw shaft 31, and is connected to the first drive system 5 through a second drive shaft 36 in a drive connection part 35 protruding from the lower surface of the cover fitting 1.
Similarly, the second drive system 6 is configured to receive drive rotational force from the manipulator.

The rotation of the second drive shaft 36 is transmitted as rotation to the screw shaft 31 via the bevel gears 37 and 34.

This threaded shaft 31 is formed with a first threaded part 31a and a second threaded part 31b, and these threaded parts 31a,
b are formed as screws in opposite directions, and the clamping pieces 32a, 32 are attached to these screw portions 31a, 31b, respectively.
b are screwed together one by one.

Rollers 38 are installed on both sides of these clamping pieces 32a and 32b, and the side walls 4 of the frame 2
1 is used as a rail 42 to facilitate smooth movement of the clamping pieces 32a and 32b back and forth.

Therefore, when the screw shaft 31 rotates, both clamping pieces 32
Since the screw directions of a and 32b are different, both clamping pieces 32a
, 32b simultaneously perform an approach operation or a separation operation.

When the holder 3 is in the lowered position, the first
As is clear from the figure, these clamping pieces 32a, 32
Since the connecting shafts 18 are located at a lower position than the upper end of the connecting shafts 18, these clamping pieces 32 are
The cover E set in the holder 3 is clamped by driving the holders a and 32b closer together.
Both halves can be glued together and placed over electric wires, etc.

After completing this covering work, if the second drive shaft 36 is reversed and the clamping pieces 32a, 32b are driven in the direction of separation, the return behavior of the coil spring installed in the holder 3 can be improved in this embodiment. Therefore, the holder 3 is opened downward.

By operating the first drive system 5 to move the holder 3 to the raised position, the cover holder 1 can be removed from the wire.

In addition, this fruit II! In the example, the holder 3 is opened by a coil spring, but the clamping pieces 32a,
If the holder plate is connected to 32b, the clamping piece 32
It is also possible to open the holder 3 by moving the doors a and 32b.

Further, it goes without saying that when configuring the clamping device j4, the same function can be achieved even if a known advancing/retracting means is used instead of the screw shaft 31.

By configuring the cover fitting device 1 in this way,
Since the cover covering device 1 can be attached to an existing live-line work manipulator and the work of covering ITS etc. with the cover E can be done remotely, the mental and physical burden on the worker is reduced.

Next, a second embodiment will be explained with reference to FIGS. 4 and 5. Although this embodiment has differences from the first embodiment described above, it also has many common features, so the following explanation will not be repeated. The same reference numerals as in the first embodiment will be given to the drawings for common points, and the explanation will be omitted.

First, in this embodiment, the first
A drive system 5 corresponding to the drive system 5 is not provided, and the cover cover device 45 consists of a frame 46, a holder 47, and a clamping device 4.
8, and the arrangement of the holder 47 and the clamping device 48 with respect to the frame 46 is different from the first embodiment.

The frame 46 is formed into a generally downwardly opening box-like shape, and a drive connection part 51 is installed on the top surface of the frame 46, and a drive connection part 51 is installed on the top surface of the frame 46. The structure is similar to that of the second drive system 6 of the first embodiment, so that the screw shaft 55 is rotated by the screw shaft 55, and the fixing pieces 56a and 56b move toward or away from each other as the screw shaft 55 rotates. .

Then, on both outer sides of the side wall 41 of the frame 46 which is on the side of the central portion of the screw shaft 55, holders 47 are installed via mounting pins 57 so as to open downward, and the holder plates 11° on both sides 12 are connected by a connecting shaft 18 and a connecting member 19, respectively.

The clamping pieces 56a, 56b are formed to protrude downward.
Since the lower end of 6b is located below the connecting shaft 18, the holder can be closed by moving the clamping pieces 56a and 56b closer together.

In addition, in this embodiment, as described above, the frame 4
6 is a clamping piece 56a having a downwardly opening shape.

56b is shaped to hang down from the screw shaft 55, so the rail 42 on which the roller 38 rolls is formed at the lower edge of the side wall 41.

In the second embodiment configured in this manner, the cover E is set inside the holder 47 as in the first embodiment, and the screw shaft 55 is rotated to drive the clamping pieces 56a and 56b closer together. Similarly to the first embodiment, the cover E can be placed over the electric wires, etc., and the cover cover device 45 can be removed from the 14 wires etc. by reversing the drive shaft 52.

As described above, this embodiment has the advantage that the structure is simpler than the first embodiment described above, so that the cover covering device is light in weight and the load applied to the manipulator is small.

(Effects of the Invention) Since the present invention is configured as described above, the cover holder having the cover between the plates is closed by driving the clamping device, and the work of putting the cover over the electric wire etc. can be done remotely. Since the cover can be placed on the cover without requiring any manual work, the worker's physical fatigue and mental stress due to electric shock or falling accidents are eliminated, and the burden on the worker is reduced.
