Description

TECHNICAL FIELD The present invention relates to a device suitable for mounting a damper on a power transmission line in order to prevent twisting of an overhead line (hereinafter referred to as a power transmission line) such as an overhead wire. .

[Conventional technology]

When snow adheres to an overhead power 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).

The torsion prevention damper is, as described in “Handbook of Wires, Bare Wires and Accessories”, 1986 Edition, pages 332 and 359, issued by Furukawa Electric Co., Ltd., as shown in FIGS. And a weight attached to the lower part of the vehicle.

As shown in the above-mentioned page 332 and Japanese Utility Model Application Laid-Open No. 63-90928, this gripping device 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 rod and switching the compression spring between a high pressure state and a non-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.

When attaching the damper to the power transmission line, an armor rod is wound around the power transmission line, and a gripping tool is attached to this. As shown in JP-A-58-182408, as a traveling means of a traveling device that travels on an overhead power transmission line, it is possible to roll the power transmission line 2 There are one sheave, two clamping means for clamping the power transmission line 1, and a moving means for moving one of the clamping means back and forth along the power transmission line. Alternatively, as shown in JP-A-59-148504, there is also one in which sheaves are used as driving wheels.

[Problems to be solved by the invention]

The installation of the twist prevention damper is a very difficult task because a person manually suspends it from the power transmission line in a suspended state. The anti-torsional damper has a considerable weight, and there is a danger of accidental dropping when installing.

 For this purpose, a damper mounting device may be developed.

In this case, the diameter of the transmission line varies. It is preferable that the damper mounting device can be shared as much as possible even if the diameter of the transmission line changes. As for the damper, a clamp hole for clamping the transmission line must be formed corresponding to the diameter of the transmission line, but other external dimensions can be the same.

Therefore, if the mounting device is fixed, the distance from the center of the power transmission line to the reference position where the damper is mounted changes depending on the diameter of the power transmission line. For this reason, it is difficult to attach the damper normally.

Note that this also applies to other attachment devices for attaching various components to the power transmission line. For example, there is an armor rod winding device. The same applies to a device for removing a component attached to a transmission line.

An object of the present invention is to provide a traveling device that can cope with changes in the diameter of power transmission lines.

[Means for solving the problem]

The present invention hangs a device for mounting a component through a sheave capable of traveling on an overhead wire, provides an axis connecting the sheave and the device as an eccentric shaft, and rotates the eccentric shaft to fix the shaft at a plurality of positions. It is characterized by being made possible.

[Action]

If you rotate the eccentric shaft according to the wire diameter of the overhead wire and fix it at a predetermined position, the distance between the sheave and the reference position of the mounting device for the parts can be made constant, so that it is possible to handle multiple types of overhead wires An attachment device can be used.

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, on the ground, the wire diameter of the transmission line 201 is set so that the height from the reference position of the mounting machine 100 (the position of the clamp holes 212a and 214a of the mounted damper 210) to the sheaves 5, 6, and 7 is constant. Operate and fix the levers 81, 81 corresponding to. In the figure, turning the lever 81 counterclockwise corresponds to a large wire diameter. The vertical position of the pressurizing wheel 56 associated with this operation is corrected by the rotation of the spring 76 and the link 57, and the like. Also, pin 57
It may be possible to correct the hole as a long hole in the vertical direction.

First, lift the mounting device on the steel tower, and set the frame 10, 11, 12
From the opening side of the mounting device to the sheave 5,
Put 6, 7 on the transmission line 201. The sheave 7 should be on the front end side.

Next, the hook 63 is hooked on the knuckle pin 65. Next, the lever 77 is rotated upward from below. The lever 77 does not move by hitting the stopper 78. As a result, the pressure wheel 56 is crimped to the power transmission line 201.

A pressure wheel is attached to the shaft 67 at the tip of the link 59 that rotates vertically.
Since the 56 and the hook 63 are attached, the structure of the vertical movement can be simplified. Further, since the interval between the hooks 63 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 63 is fixed to the rod 66.

Next, the rotary seat 130 is raised to an obliquely upper position by the motor 144 of the mounting machine 100. Next, the handle 135b is pulled to insert the spacer 138. Further, the support rod 151 is raised.

Next, pull out the hook 215a of the hook bar 215 of the damper 210 from the hole 214c of the clamp cap 214 to remove 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. The clamp body 212 is a rotating seat
It faces 130 side. And the reference seat 21 of the clamp body 212
Put 2e and 212e in the seats 152 and 152. This allows the damper
210 is held horizontally. Transmission line 201 has traveling holes 212b and 214
Located at b.

Next, hold the eccentric cam 216 and hook 215a of the hook bar 215.
Is pushed into the hole 214c of the clamp cap 214 and then rotated 90 degrees. As a result, the damper 210 is brought into the state shown in FIG. The hole 216b of the eccentric cam 216 faces obliquely upward. Since the compression spring 218 maintains the distance between the clamp body 212 and the clamp cap 214, the clamp cap 214 does not come into contact with the power transmission line 1 during traveling. Compression spring 218 is hook bar 2
Since it is supported by 15, the clamp cap 214 does not fall off even if it is detached from the hook rod 215.

Next, the eccentric cam 216 is slightly rotated in the up and down direction by hand, and the hole 216b is directed toward the tip 135a of the operation pin 135.
In this state, pull out the spacer 138 to remove the tip of the operation pin 135.
Insert 135a into hole 216b.

Further, the electric cylinder 123 is operated so that the arm 124 presses the reference seat 212e.

The support rod 151 is rotated to insert the pin 151c into the hole 231. As a result, the inclination of the damper 210 in the radial direction of the transmission line 201 is eliminated, and it is brought into contact with the snow-resistant ring,
It is possible to prevent the normal mounting from being hindered.

In this state, the attachment 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 100 approaches the armor rod 202, a worker on the ground moves the mounting device inching. When the clamp holes 212a, 214a of the damper 210 are located substantially in the center of the armor rod 2 in the longitudinal direction, the traveling is stopped. A worker on the ground operates the command device by looking through the binoculars.

Next, the motor 114 is operated to lower the damper 210 to the middle position. As a result, the armor rod 202 is
Located at 12a, 214a. Further, the pin 151c comes out of the hole 231.

Next, the motor 144 is operated to lower the rotary table 130, that is, the operation pin 135 downward. As a result, the eccentric cam 216 rotates to be in a strongly compressed 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
Receive on the vertical plane.

Next, after retracting the rod of the electric cylinder 123, the motor 114 is operated to lower the elevating seat 116, that is, the turntable 130 to the lower position. Since the hole 216b of the eccentric cam 216 and the operation pin 135 face the vertical direction, the tip of the operation pin 135
The 135a exits downward from the hole 216b.

Next, in this state, the motor 16 is rotated in the reverse direction so that the mounting device runs in the reverse direction and the steel tower collects the steel.

At this time, the sheave 7 will get over the top of the damper 210, but the frame 10 on which the sheave 7 is installed has a sheave.
Since it is inclined with respect to the rocking frames 7a, 7b on which the 5, 6 are installed, it is possible to get over the tamper 210. At this time, since the rear wheel is only one of the sheaves 7, the rear wheel is also tampered with as compared with the case where two sheaves are installed on the swing frame.
Even if there is a large amount of upward protrusion of the top of 210 (for example, 2c
m) It can be easily overcome.

Since both sides of the damper mounting machine are supported by sheaves 6 and 7, the axes of the running holes 212b and 214b and the power transmission line are always parallel, and the running holes come into contact with the snow-retaining ring, which is easy to drop when running. It is possible to prevent the accident. Moreover, since the clamp holes 212a and 214a and the power transmission line are parallel to each other when the damper is attached, the attachment can be favorably performed.

Further, since the sheaves 5 and 6 swing with respect to the frame 10, it is possible to easily get over the armor rod 202 and the snow-hardening ring when moving forward and backward. For this reason, difficult-to-fall snow rings that do not fall off are not dropped by sheaves.
Can drive.

Since sheaves 5 and 6 swing with respect to sheave 7,
The claim 10 (that is, the axis of the clamp holes 212a, 214a) can be parallel to the power transmission line 201 between the sheaves 6 and 7, and the damper 210 can be attached to the power transmission line 201 well.

Further, since the sheaves 5 and 6 which are driving wheels for traveling are swung, it is possible to prevent the snow-difficulty ring, which easily falls off, from falling off.

When there is no sheave 7, as shown in FIG.
The mounting device is suspended from the power transmission line 201 with the sheaves 5 and 6 as base points. For this reason, the damper 210 placed at the tip of the mounting device
Since the centers of the clamp holes 212a, 214a are inclined with respect to the power transmission line 201, a mounting failure of the damper 210 may occur.
Also, since the mounting device is supported by three sheaves 5, 6, 7,
The surface pressure is reduced and the falling snow ring can be prevented from falling off.

To remove the attachment device from the power transmission line 201, rotate the lever 77 downward, then remove the hook 63 from the knuckle pin 65, and then perform the operation.

If the mounting device has been recovered to the steel tower, after raising the lifting seat 66 and the support rod 151 to the upper position, the above operation is repeated,
Attach a damper to the armor rod before the armor rod to which the damper was attached in the previous work.

The operation pin 135 that engages with the eccentric cam 216 has a shape of an eccentric cam.
216 are provided.

In the above embodiment, the operation pin 135 is clamped by rotating it from the upper side to the lower side. Since there is no obstacle below the two weights 225, 225, the operation pin 135 can be removed from the eccentric cam 216 by lowering the elevating seat 116 after rotating the operation pin 135 downward. Therefore, the configuration can be simplified. In particular, operating pin 13
Since the lowering of 5 can be performed by the motor 114, the configuration can be simplified.

 Note that the traveling device may be a known device.

The configuration of the eccentric shafts 21 and 91 and the lever 81 for changing the distance from the sheave to the reference position of the mounting machine can be used for other mounting devices. For example, in order to mount the damper, the armor rod 202 is wound around the power transmission line in advance, and this can be used for this winding device. However, in the case of the armor rod wrapping machine, the number of armor rods and the wire diameter thereof differ according to the wire diameter of the power transmission line 201, so that the wrapping machine itself needs to be slightly replaced. However, the traveling device, the driving device of the winding machine, and the like can also be used.

〔The invention's effect〕

According to the present invention, even if the diameter of the overhead wire changes, the distance from the sheave to the reference position of the mounting machine can be made constant, so that it can also be used as a traveling device of the mounting device.
