Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is suitable for an apparatus for attaching parts to an overhead transmission line, and particularly suitable for attaching a damper to be attached to an overhead transmission line in order to prevent twisting of the overhead transmission line. Related to the device.

In the present invention, the attachment of the component includes the removal of the component from the power transmission line.

[Conventional technology]

If snow adheres to the overhead transmission line, the transmission line is cut or the transmission line is twisted. As means for preventing the torsion, a device called a damper is provided at a predetermined interval on the transmission line. About 3 dampers are installed between one tower (interval is about 400m).

This torsion-prevention damper is described in “Electrical Handbook, Bare Wires and Accessories,” 1986 Edition, Furukawa Electric Co., Ltd.
As described on page 59, it comprises a gripper for gripping the outer surface of the transmission line and a weight attached to the lower part of the gripper.

As shown in the above-mentioned page 332 and Japanese Utility Model Application Laid-Open No. 60-3113, the gripping tool is rotatably connected to a clamp body having a suspended weight and an upper end of the clamp body. And a compression spring disposed between the lower portion of the clamp cap and the clamp body and acting to expand the two, and penetrating the lower portion of the clamp cap and the clamp body to engage with the clamp body. And a eccentric cam attached to the tip of the hook bar and switching the compression spring between a high pressure state and a specific high pressure state. The gripper grips the transmission line by rotating the eccentric cam to a position in a high pressure state with the construction jig.

In attaching the damper to the power transmission line, an armor rod is wound around the power transmission line, and a gripping tool is mounted on the armor rod. As shown in JP-A-58-182408, the traveling device of the traveling device that travels on the overhead transmission line is a device that rolls the transmission line. There are two sheaves, two clamping means for clamping the transmission line 1, and a moving means for moving one of the clamping means back and forth along the transmission line. Alternatively, as disclosed in JP-A-59-148504, there is also a type in which a sheave is used as a driving wheel.

[Problems to be solved by the invention]

The installation of the torsion prevention damper is performed by hand by a person suspended in the air on the power transmission line, which is a very difficult task. The anti-torsional damper has a considerable weight, and there is a danger of accidental dropping when installing.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to easily and reliably mount or remove components from a power transmission line using a machine.

[Means for solving the problem]

The present invention relates to a traveling device that rolls on a power transmission line and has three sheaves arranged along a longitudinal direction of the power transmission line; It is installed in the traveling device between the sheave and the support device for mounting a component for mounting on the power transmission line or a component mounted on the power transmission line, and by raising and lowering the external support means, A mounting machine for mounting or removing parts, and a rotatably holding the sheave on the one end side, wherein an upper part of the sheave on the one end side is rotated in the above direction around a horizontal rotation axis. A holder installed on the traveling device, and a portion of the holder above the rotation axis and below the rotation shaft so that the sheave on the one end side rises when the support means is lowered. of Serial characterized by constituting the tie rod for connecting the support means, the component mounting apparatus to the power transmission line from.

[Action]

Now, the case where the component is mounted on the power transmission line will be described. The component is placed on the support means, the traveling device is run with the one end side sheave at the front end side, and the mounting machine is operated at the target position to mount the component. When installation is completed,
Since the support means is lowered, the holder is rotated by the tie rod, and the sheave at the one end is raised. In this state, the traveling device is moved backward. Therefore, since the sheave does not come into contact with the components attached to the transmission line, the attachment device can be retracted. Further, since the driving means for vertically moving the sheave is generated by the vertical movement of the support means, the structure can be simplified.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 23. This embodiment is a damper mounting device.

It is deviated in the horizontal direction from the axis of 38a.

The center 38b of the eccentric shaft 38 is eccentric with respect to both ends supported by the brackets 37,37. By pivoting the lever 47 upward from below, the shaft portion 38b is eccentric so as to move upward from below. Therefore, by rotating the lever 47 upward from below, the reference seat 40 and the movable seat 4 are moved.
5, and the rod 36 moves upward.

When the lever 47 is positioned below, there may or may not be a gap between the reference seat 40 and the moving seat 45, but in this embodiment, there is no gap. That is, the moving seat 45 is pressed against the reference seat 40. If there is no gap, a preload can be applied to the compression spring 46, and a large pulling force of the rod 36 can be obtained with a small amount of eccentricity of the eccentric shaft 38.

FIG. 8 shows another embodiment of the pressing means. The screw rod 43 is fixed to the moving seat 45 and penetrates the reference seat 40. The compression spring 46 is disposed between the reference seat 40 and the nut 44.

As a means for moving the reference seat 40 up and down, for example, an electric cylinder is attached to the bracket 37 so as to face vertically, and a rod of the electric cylinder is connected to the reference seat 40.

A sprocket 62 is mounted on the shaft 64. Sprockets 61 and 62 are connected by a chain 63.

The screw rod 59 meshes with a nut 67 of the lifting seat 66. Therefore, the lifting seat 66 is moved up and down by the motor 64. The lifting seat 66 can be moved only in the vertical direction by the sliding seat 68 meshing with the rail 58.

The operation of the motor 64 causes the lifting seat 66 to move as described later.
Stops at three positions: upper, middle, and lower. The upper position is a position where the damper 210 is mounted and the mounting device travels toward the armor rod 202. The middle position is lower than the upper position, and the damper 210 is operated by operating the operating means.
This is the position where 02 is clamped. The lower position is a position below the middle position where the operating means is separated from the damper 210 after the damper 210 is clamped on the armor rod 202, and the mounting device is moved toward the original position. .

The positions of the upper ends of the vertical seat 56 and the lift seat 66 are positions at which the handle 85b of the operation pin 85 does not hit even when the turntable 80 described below is rotated with the lift seat 66 in the middle position.

 The above configuration constitutes the elevating means.

On the surface of the lifting seat 66 on the side of the transmission line 1, the reference seat 12e of the damper 10 is provided.
Supports 71, 71 for supporting 12e are provided. Support 71
Is a plate. The support base 71 is provided with a concave receiving seat 72 for supporting the reference seat 12e. The shape of the receiving seat 72 corresponds to the shape of the reference seat 12e. On the outer surface of each support 71,
An electronic cylinder 73 and an arm 74 operated by a motor or an electromagnet are provided. The arm 74 rotates about the pin 75.
The tip of the arm 74 is bent toward the other support base 71 side. Therefore, when the rod of the electric cylinder 73 is protruded, the tip of the arm 74 is located on the upper surface of the reference seat 12e. For this reason, the drop of the damper 10 can be prevented. Electric cylinder 73
Is fixed to the support base 71 so as to be rotatable in the vertical direction.

 The above configuration constitutes the support means.

A U-shaped turntable 80 is provided between the upper portions of the two support stands 71, 71 so as to be rotatable in the vertical direction about the bearings 81, 81.
An operation pin 85 is inserted through a U-shaped bottom hole 80a of the turntable 80. The tip 85a of the operation pin 85 can enter the hole 16b of the eccentric cam 16. C fixed to turntable 80 and tip 85a
A compression spring 84 is disposed between the retaining ring 86 and the retaining ring 86. The other end 85b of the operation pin 85 has a large diameter and is a handle. When the grip 85b is pulled by hand, the compression spring 84 can be contracted.

A detachable spacer 88 between the handle 85b and the turntable 80
Has been arranged. The spacer 88 is U-shaped and has an operation pin
85 can be moved in the radial direction. When the spacer 88 is removed, the tip 85a of the operating pin 85
Enter 6a. When the spacer 88 is inserted, the operation pin 85
Get out of. The spacer 88 is connected to the vertical seat 56 by a chain 89.

Bearings 81, 81 supporting shafts 80b, 80c at both ends of a U-shaped turntable 80
Are inserted and fixed in recesses 71a, 71a provided at the upper ends of the support bases 71, 71. A sprocket 92 is fixed to a shaft 80c protruding toward the frame 45 side. An electric geared motor 94 is mounted on a support base 71 below the shaft 80c via a seat 93. A sprocket 95 rotated by a motor 94 is provided between the support 71 and the seat 93. Sprocket 95 and sprocket 92 are linked by chain 96.

The operation of the motor 94 causes the turntable 80 to move as shown in FIGS.
There are two positions: an obliquely upper position as shown in FIGS. 16 and 17, and a lower position as shown in FIG. The diagonally upper position is the damper
This is a position where the vehicle 10 runs while the damper 10 is mounted, and is a position where the damper 10 is clamped to the armor rod 2. When the turntable 80 is rotated from an obliquely upper position to a lower position, the operation pin
The eccentric cam 16 is rotated by 85, and the damper 10 clamps the armor rod 2. The lower position is a position where the mounting device is moved toward the original position.

The above configuration constitutes the operation means. The operation pin
85 corresponds to the engaging tool.

Next, the configuration of the auxiliary traveling device 100 will be described with reference to FIGS. Rotary shaft 10 installed at the end of frame 10
5, a holder 104 to which a sheave 101 is attached is suspended.
At one end of the rotating shaft 105 (that is, an end of the frame 13 facing one vertical side), a lever 107 is provided for information. Pin 108 and mounting machine installed horizontally at the tip of lever 107
The tie rods 110 are connected to the fifty vertically movable supports 71. The pin 108 is engaged with the elongated hole 111 at the upper end of the tie rod 110. The lower end of the tie rod 110 is connected to the support base 71 via a pin 115 and a bracket 116. 119 is a turnbuckle.

In a state where the mounting device is traveling with the damper 210 mounted thereon, that is, in a state where the lifting seat 66 is raised to the upper position, the pin
Since 108 is pushed up by the tie rod 110, the holder 10
4 has a rear surface on the seat 109 of the frame 10. In this state, the rotation center 102 of the sheave 101 is located closer to the traveling device 1 than the vertical line of the rotating shaft 105 of the holder 104 (that is, rearward in the traveling direction of the mounting device). The adjustment is made with the turnbuckle 119 so as to be in this state. Sheave 101 is transmission line
The state of being mounted on 201 is when the lifting seat 66 of the mounting machine 50 is in the upper position and the middle position. When the elevator 66 is in the lower position,
The holder 104 is rotated upward.

As described above, the auxiliary traveling device 100 includes the holder 104 having the sheave 101, the link mechanism including the lever 107 and the tie rod 110, and the attaching device 50 of the driving means.

Next, an operation of attaching the damper 210 to the power transmission line 201 arranged between one steel tower will be described.

Before the mounting work of the damper 210, the armor rod 202 is mounted at the mounting position of the damper 210. This armor rod may be wound manually by a worker as in the prior art.
As shown in Japanese Patent No. 249818, the power transmission line 1 is wound by a running winding device. Armor rod 202 is about 100 between one tower
Approximately three are arranged at mm intervals. A known snow-resistant ring is attached to the transmission line 201. This snow-resistant ring is mounted by a mounting device disclosed in Japanese Patent Application Laid-Open No. 58-182408 or Japanese Patent Application No. 62-29622. The snow resistant rings are attached at predetermined intervals.

After the above operation, the mounting device is run to mount the damper 210. The damper 210 starts mounting from the armor rod 202 at the farthest position with respect to one of the towers,
Attached to the nearby armor rod 202. For this reason, the attachment device can travel on the snow-resistant ring and the armor rod 202.

 Next, a detailed procedure will be described.

First, the mounting device is lifted on a steel tower, and frames 10, 11, 12
From the opening side of the mounting device to the sheave 5,
The 6,101 is placed on the transmission line 201. The sheave 101 is set to the front end side.

Next, the hook 33 is hooked on the knuckle pin 35. Next, the lever 47 is rotated upward from below. The lever 47 does not move by hitting the stopper 48. As a result, the pressure wheel 26 is crimped to the transmission line 201.

Pressing wheel on the shaft 37 at the tip of the link 29 that rotates vertically
Since the hook 26 and the hook 33 are attached, the structure of the vertical movement can be simplified. Further, since the interval between the hooks 33 is larger than the thickness of the sheave 5, the interval between the sheaves 5 and 6 can be reduced, and the length of the mounting device can be shortened.
The same applies when the hook 33 is fixed to the rod 36.

In order to place the sheave 101 on the power transmission line 201, the elevator 66 must be raised to the upper position by the motor 64. When the elevator 66 is in the upper position, the holder 104 is rotated downward via the tie rod 110, and the sheave 101 is placed on the power transmission line 101.

Next, the rotary seat 80 is raised obliquely upward by the motor 94 of the mounting machine 50. Pull the handle 85b to the spacer 8
Insert 8.

Next, the hook 215a of the hook bar 215 of the damper 210 is pulled out from the hole 214c of the clamp cap 214, and the clamp cap 2
The damper 210 is lowered from above the power transmission line 201 by expanding the space between 14 and the clamp body 212. Clamp body 212 is a rotating seat
It is facing 80 side. And the reference seat 212 of the clamp body 212
e, 212e are placed in seats 72, 72. This allows the damper 210
Is kept horizontal. Transmission line 201 is located in traveling holes 212b and 214b.

Next, hold the eccentric cam 216 and hook 215a of the hook bar 215.
Is pressed into the hole 214c of the clamp cap 214, and then rotated 90 degrees. This brings the damper 210 into the state shown in FIG. The hole 216b of the eccentric cam 216 faces obliquely upward. Since the compression spring 218 keeps the gap between the clamp body 212 and the clamp cap 214, the clamp cap 214 does not contact the transmission line 1 during traveling. Compression spring 218 is hook bar 2
Since the clamp cap 214 is supported at 15, it does not fall off even if the clamp cap 214 is removed from the hook bar 215.

Next, the eccentric cam 216 is slightly rotated in the vertical direction by hand, so that the hole 216b is directed toward the tip 85a of the operation pin 85. In this state, pull out the spacer 88 and move the tip 85a of the operation pin 85.
Into hole 216b.

Further, the electric cylinder 73 is operated, and the reference seat 212e is pressed by the arm 74.

In this state, the mounting device can run toward the armor rod.

Next, the tower operator communicates the completion of the preparation to the ground worker. As a result, the operator on the ground operates the command device to operate the motor 16 to move the mounting device toward the target armor rod 202.

When the mounting machine 50 approaches the armor rod 202, the worker on the ground makes the mounting device inching-travel. When the clamp holes 212a and 214a of the damper 210 are located substantially at the center in the length direction of the armor rod 2, the traveling is stopped. An operator on the ground operates the command device by looking through the binoculars.

Next, the motor 64 is operated to lower the damper 210 to the middle position. As a result, the armor rod 202 is
Located at 12a, 214a.

Next, the motor 94 is operated to rotate the turntable 80, that is, the operation pin.
Lower 85 downward. This allows the eccentric cam 21
6 rotates to a strong compression state, and the damper 210 is fixed to the armor rod 202.

The reaction force of the damper 210 due to the rotation of the eccentric cam 216 is received on the vertical surface of the seat 72.

Next, after retracting the rod of the electric cylinder 73, the motor 64 is operated to lower the elevating seat 66, that is, the turntable 80 to the lower position. Since the hole 16b of the eccentric cam 216 and the operation pin 85 are oriented vertically, the tip 85a of the operation pin 85 is
Exit downward from b.

As a result, the tie rod 110 is pulled downward, so that the sheave 101 moves up about the shaft 103. At this time, the position of the lower surface of the sheave 101 is higher than the upper surface of the damper 210 fixed to the armor rod 202. In this state, the mounting device is supported on the transmission line 201 by the sheaves 5 and 6.

Next, in this state, the motor 16 is rotated in the reverse direction so that the mounting device runs in the reverse direction, and is collected in the steel tower. To remove the mounting device from the transmission line 201, the lever 47 is rotated downward, and then the hook 33 is removed from the knuckle pin 33, and then the mounting device is removed.

Since the upper end of the damper 210 largely protrudes upward from the transmission line 201, the sheave 101 cannot cross over it. Therefore, if the sheave 101 is not provided, the weight of the damper 210 is about 5 kg or more.
The weight added to 6 increases, and the attached snow-resistant ring is dropped.

When the sheave 101 is not provided, as shown in FIG. 24, the mounting device is hung from the transmission line 201 with the sheaves 5 and 6 as base points. For this reason, a damper placed at the tip of the mounting device
Since the centers of the clamp holes 212a and 214a of the 210 are inclined with respect to the power transmission line 201, a mounting failure of the damper 210 may occur.

However, since the tip of the mounting device is supported by the sheave 101 until the mounting of the damper 210 is completed, the occurrence of such a problem can be prevented.

In addition, as a driving means for vertical rotation of the sheave 101, an electric cylinder or the like may be provided between the lever 106 and the frame 13, but this is performed by using the lifting and lowering of the damper mounting machine 50, so that the configuration is Can be easily done. Until the mounting of the damper is completed, it can be mechanically supported by the sheave 101.

The rotation center 120 of the sheave 101 is located behind the rotation center 105 of the holder 104. If the rotation center 102 of the sheave 101 is set below the vertical line of the rotation center 105 of the holder 104, when the lifting seat 66 is lowered to the middle position, the pin 10
8 is located in the middle of the elongated hole 111.
It is conceivable that 104 rotates upward. In order to prevent this, the rotation center 102 is provided behind the rotation center 105.

In addition, even when an elongated hole is not provided in the connecting portion between the pin 108 and the tie rod 110, the rotation center 102 of the sheave 101 is located behind the rotation center of the holder 104. The rotation center 102 is provided so as to be located behind the rotation center 105 even when the lifting seat 66 is lowered to the middle position. According to this, substantially the same effect as when the elongated hole 111 is provided can be obtained.

Since the sheaves 5 and 6 are pressed against the power transmission line 201 by the pressurizing wheel 26, the sheaves 5 and 6 can easily travel even on an inclined portion of the power transmission line 201.

When the mounting device has been recovered to the steel tower, the elevator 66 is raised to the upper position, and the above operation is repeated, and the damper mounted on the armor rod before the armor rod to which the damper was mounted in the previous operation is mounted.

To mount the mounting device on the transmission line 1, in FIG.
This is done by moving the mounting device from left to right. For this reason, the worker is often located on the left side. The handle 85b of the operation pin 85 of the mounting machine 50 is located on the left side. Therefore, the operator can easily operate the operation pin 85 into the spacer 88 and the eccentric cam 16. Of course, the position of the operation pin 85 may be reversed.

 The vertical seat 56 may be on the electric cylinder 73 side, for example.

The shape of the operating pin 85 that engages with the eccentric cam 16 is
Provided corresponding to.

In the above embodiment, the operation pin 85 is clamped by rotating it downward from above.
Since there is no obstruction below the two weights 25, 25, the operation pin 85 can be pulled out from the eccentric cam 16 by rotating the operation pin 85 downward and then lowering the elevating seat 66. . Therefore, the configuration can be simplified. In particular, since the operation pin 85 can be lowered by the motor 64, the configuration can be simplified.

Since the reference seat 12e and the receiving seat 72 have vertical surfaces, it is possible to take a reaction force when operating the eccentric cam.

 Note that the traveling device may be a known device.

In the above embodiment, a device for mounting a damper on a transmission line has been described. However, the present invention can be applied to devices other than the damper. Further, it can be used not only for mounting but also for removing the damper. That is, after the operation pin is engaged with the eccentric cam, the lifting seat is raised, whereby the damper is removed, and then the lifting seat is lowered.

〔The invention's effect〕

ADVANTAGE OF THE INVENTION According to this invention, while attaching and detaching components from a transmission line can be easily performed, a structure can be simplified.
