Furthermore, when attaching the SR ring to the electric wire, as described above, the ring attachment device is positioned relative to the electric wire, and the support frame 22 of the ring supply unit 20 is moved onto the electric wire by the drum lateral movement device 25. By moving the SR ring along the guide 23 and stopping it at the position where the horizontal rollers 15.15a provided on the support frame 22 touch the electric wire A, the SR ring can be attached to the electric wire. Positioning is performed.

Then, in the above-mentioned state, while the ring mounting device is running, the ring mounting device 30 is driven to perform the work of mounting the SR ring. In addition, when replacing the ring supply unit, the drum lateral movement device 2
5 is reversely driven to separate the ring holding device 20 from the electric wire, the ring supply unit is removed from the ring holding device, and a ring feeding unit containing another SR ring is attached to the ring holding device. In addition, in the ring mounting apparatus of the present invention, it is also possible to replenish the SR ring to the ring supply cornit midway, but such work will be explained in detail later.

(Structure of Ring Supply Unit) In the embodiment of the ring supply unit of the present invention shown in FIGS. 4 and 5, the ring holding device! ! Reference numeral 21 is configured as a holding member for the SR ring along the cylindrical surface, and is supported by the support frame 22 via the upper plate member 40 provided on the upper part thereof, as shown in FIG. Fixed via.

The ring holding device 21 is provided with a spiral guide 43 on the inner surface of an outer frame 42 configured to follow a cylindrical surface, and when the opening of the SR ring 90 is attached,
The spiral guide 43 is supported by a rail member 44. A drum member 57 rotatably supported with respect to a support shaft 58 is disposed in the inner space of the outer frame 42, and the drum member 57 is configured to align the SR ring along a spiral guide, as will be described later. It is used to support the wire around it when moving it.

Moreover, the SR ring supported by the spiral guide 43 is
In the case of this embodiment, more than 1,000 SR rings can be accommodated, and a ring drive device 60 is provided to sequentially feed out the SR rings toward the mounting section.

As shown in FIG. 5, a turning section guide 45, a linear guide 46, and an exit guide 47 are connected to the spiral guide 43, respectively, and these guide means guide the SR ring to the mounting section. I try to guide people up to 50. Note that the two guides 46 and 47 are provided inside the upper plate member 40.

Among the guide means 45 to 47 for the SR ring, the turning portion guide 45 is supported in a state where the rail member enters the inside of the opening of the SR ring, similarly to the spiral guide 43. Moreover, in the linear guide 46 and the exit guide 47,
As shown in FIG. 5a, the groove 46a of the guide member 46
The ring is guided when the SR ring 0 is inserted into the inside of the ring.
The R-ring is moved toward the mounting section. Further, a mounting part 50 is disposed at the end of the exit guide 47, and in the mounting part 50, a ring is mounted between the exit guide 47 and the end support member 52. A gap 51 is provided that is large enough to allow the user to enter.

The end support member 52 is provided with a through hole 55 that opens in the direction of the electric wire, and a ring stopper 53 and a spring 54 that biases the ring stopper are provided inside the hole. Then, by urging the ring stopper toward the inside of the hole by the spring 54, the SR ring at the most distal end is locked. The means for locking the end support member 52 with respect to the SR ring will be explained in detail later, but when replenishing rings, the SR ring is pushed from the end support member toward the guide member. It also acts as a locking means for the SR ring.

In the ring supply unit of the present invention described above, as shown in FIG. A linear guide 46 is arranged to gradually approach the turning section guide 45 with respect to the electric current 11A, and a 10th line guide 46, which will be described later, is arranged in the exit guide 47 section.
As shown in Figure (a), the SR cling 0, which is opened in a substantially 3-shape, is arranged so that its hinge portion can be slid onto the electric wire. Therefore, when attaching the SR rings while moving the device along the electric wire A, a small number of SR rings slide onto the electric wire A only at the exit guide 47. Therefore, for example, even if the SR ring is used to scrape off rust when the electric wire has rust, it is possible to prevent a large amount of iron debris from accumulating on the inner surface of the SR ring. . Furthermore, by setting the inclination angle of the linear guide 46 with respect to the electric wire to be relatively large, the number of SR rings that slide on the electric wire before installation can be reduced, and the occurrence of the above-mentioned problems can be prevented as much as possible. You can.

As described above, the SR supported by the spiral guide 43
In order to send out the ring 0, a ring drive device 60 is used in the ring holding device of the present invention. The ring drive device 60 is composed of a spring motor 61 disposed inside the drum member 57, a take-up pulley 62, and a wire 63 driven through the take-up pulley 62, and the wire 63 is connected to a turning pulley 65. .66 and is wound around the drum member 57.

The spring motor 61 has a spring wound between two pulley members, and when replenishing the SR ring, force is accumulated in the spring by applying a pressing force in the opposite direction to the spring motor. Then, by pulling the wire using the reaction force of the spring, the SR ring is moved in the supply direction, and a type generally called a spring motor can be used.

The ring drive device 60 is constructed as shown in FIG. 6, and has an end guide 6 at the tip of the wire 63.
7 is fixedly provided, the end guide 67 is a member having the same structure as the SR ring, and the end guide is made to slide along the spiral guide 43. The SR supported by the spiral guide 43 by the end guide 67
The rear end of the cling ring 0 is pressed so that the SR ring is pushed out one piece each time the SR ring is attached to the wire and removed from the support member. Additionally, when the end guide 67 moves to the base of the turning section guide 45 in Fig. 5 while attaching the SR ring to the wire, it is no longer possible to feed the SR ring. Therefore, the ring installation work using the device is completed.

The wire 63 is arranged so as to be wound around the drum member 57, and when the wire 63 is wound around the pulley 62, the wire slides around the drum. However, since the drum member 57 is provided to be freely rotatable with respect to the support shaft 58, when the frictional force between the wire and the drum surface is large, the drum member rotates together with the wire, causing the wire to The action of sending it out toward the take-up pulley 62 can be performed.

(Replenishment of SR rings to the ring holding device) When replenishing the SR ring to the ring holding device 21,
A mounting tool as shown in FIG. 7(a) is used. The mounting tool 70 is provided with means (not shown) for locking the ring at the tip of the handle 72, and a thin plate-shaped SR ring holding section 71 is provided at the tip thereof, and with respect to the holding section 71, Same figure (
As shown in b), with a large number of SR rings held, the work of replenishing the SR rings is carried out from the tip of the end support member 52 shown in FIG. 4 through the through hole 55. . When replenishing the SR ring, the end support member 52
When the tool 70 is inserted into the S
Since the ring stopper 53 is expanded by the R ring, the ring can be fed toward the helical guide via the outlet guide 47.

Further, when the tool 70 is removed, the SR ring at the terminal end is stopped by the ring stopper 53, so that the SR ring is prevented from being removed from the exit guide.

Then, as described above, a predetermined number of SR rings are held against the helical guide by repeating the process of gathering several dozen SR rings together using a tool and feeding them in the direction toward the helical guide. I can do it.

The SR ring replenishment operation will be explained with reference to FIG. 6. The SR ring inserted in the direction of arrow Z through the end support member 52 sequentially presses the SR ring -C which is already supported by the spiral guide 43. Therefore, the end guide 67 located at the rear end of the SR ring of the spiral guide
is moved along the rail member toward the end of the spiral. At this time, the end guide 67 acts to pull out the wire 63, so the take-up pulley 62 is rotated in the opposite direction, and the reverse rotation of the take-up pulley applies a force in the J direction to the spring king 61 to unwind the wire. Accumulated.

Therefore, when replenishing the SR ring, by storing the force for pushing the SR ring in the spring motor, the SR ring can be operated without being sent out toward the supply section.

(SR ring attachment device) In order to attach the SR ring to the electric wire A in the ring attachment device, a ring attachment device 30 having a configuration as shown in FIG. 8 can be used. As shown in FIG. 2, the ring attachment device 30 is arranged on the side of the ring supply unit 20, and is configured to move together with the ring supply unit in the direction toward and away from the electric wire, A motor 31 drives a rotating cam 32 shown in FIG.

The cam 32 is rotated by a motor via an eccentric shaft 32a, and presses the cam follower 34 of the slider 33 around the cam 32.

The slider 33 is supported by a guide member together with a spring (not shown), and is provided so as to be slidable in the left-right direction in the figure by a cam 32, through a long hole 35.35a provided at its tip. Caulking arm 36.36a
The bins 39 and 39a are respectively locked. The caulking arms 36.36a are each supported by the frame of the ring mounting device 30 via fulcrums 38.38a, and claw members 37.37 are attached to the free side tips of these arms.
A is provided. Further, as shown in FIG. 6, the claw members 37.37a are inserted into the gap 51 between the outlet guide 47 and the end support member 52, and act to tighten the SR ring.

When installing the ring 0 using the device 30, as shown in FIG.
．． 37a drives the two arm members 91 and 92 in a direction that intersects the SR ring, which is open in a substantially 3-shape, in order to move in a direction diagonally approaching the front side. Become. At that time, as shown in FIG. 9, the claw member acts to push the shoulder portions 91a and 92a corresponding to the locking portions 94 and 95 of the arm member from behind, so that the ring The fixing action can be easily performed.

In addition, in the ring attachment device of the present invention, when attaching the SR ring to the electric wire, as shown in FIG. In the open state, the hinge portion is brought into contact with the electric wire A, and the ring installation shown in FIG. 8 is performed by the device. In addition, when installing the ring, when the device is running or after the work is completed, the ring supply unit is spaced from the wire, so as shown in Figure (b), the SR Cling 0 is kept separated from the wire. be placed. The ring supply unit is moved to a position close to the electric wire only when the SR ring is attached.

(SR ring installation work) The ring installation of the present invention uses a device to attach the SR ring to the electric wire A.
The work of installing the R-ring is carried out according to the steps shown in FIG. 11. In addition, in the apparatus of the present invention, the order of the work described later is carried out according to a program installed in a control device installed in the apparatus, and the operator controls the spacing and other conditions beforehand when installing the rings. By setting this on the device, the following tasks can be performed in an orderly manner. In the flowchart shown in FIG. 11, work step b
In step -h, the ring attachment is performed while moving the device along the wire, and the operation of attaching the SR ring to the wire consists of the forward traveling in step C and the ring riveting work in step e. shall be repeated. In FIG. 11, the ring installation is performed by supporting the device on the electric wire, attaching the ring supply unit, and setting the device to the operating state.After step a, the ring supply unit is moved toward the electric wire, and the ring is attached. After passing through the step of pressing the horizontal roller of the supply unit against the electric wire to set the state in which the SR ring supported by the exit guide slides along the electric wire, the steps c-e of attaching the SR ring are carried out. The operation is repeated to attach the SR ring to the wire at predetermined intervals. When installing the SR ring, the moving distance of the device is determined by inputting the rotation information of the distance measuring roller 9 shown in FIG. 1 into the control device and determining the distance. every interval (e.g. 30aR), SR
Let's do the work of installing the ring.

Once all the SR rings housed in the ring holding device have been installed, or the SR ring has been installed over a predetermined working distance, the process will pass through step f and stop running (step q). The running of the device is stopped and the ring supply unit is separated from the electric wire (step h). Then, in this state, the ring attaching device is moved to the end of the wire to be recovered, or the ring holding device is replenished with the SR ring for the next operation.

In order to perform the operations described above, in the apparatus of the present invention, each drive means can be operated as shown in FIG. In the timing chart shown in FIG. 12, the motor 26 for moving the ring supply unit is kept in an on state from the start of the work until the end of the work, and holds the ring supply unit in a position close to the electric wire. . Also, the ring installation is done from the running motor of the device.
12, the ring is attached to the drive motor 31 of the device.
They are driven alternately, so that the SR ring is moved to a certain position and the SR ring is installed in order.

In addition, in the ring mounting apparatus of the present invention, a plurality of ring holding devices are prepared, and when one work is completed, the ring holding device can be replaced as it is to prepare for the next work. In that case, a worker waits on top of the transmission line tower, replaces the ring holding device on the self-propelled ring installation equipment, and moves the equipment to the next work section. By doing so, the installation of the SR ring can be continued.

In addition, if multiple ring holding devices are not used, once the work of one process is completed, the ring holding device must be lowered to the ground to replenish the SR rings, or the ring holding device must be placed on a steel tower to replenish the SR rings. The work of replenishing the equipment with SR rings is carried out. For example, even when replenishing 1000 SR rings, the work of replenishing the SR rings can be done easily by using a mounting tool and takes about 30 minutes. I can do it.

In addition, in the ring attachment device of the present invention as described above, it is possible to use means such as configuring the traveling means by arranging two rollers at the front and the rear to improve the climbing ability. Other detailed features can be modified to improve the performance of the device of the present invention.

Snow accretion ring installation according to the present invention, since the device has the above-mentioned configuration, the SR ring is installed with the locking part at the horizontal position with respect to the electric wire. In some cases, even if the electric wire is used to run other members after the SR ring is installed, even if the rollers of the running member pass, the S
The R ring will not be damaged.

In addition, in the ring mounting device of the present invention, since the SR ring can be supplied to the mounting part from the side,
The ring attachment can easily form a structure in which an SR ring attachment mechanism is installed in the device, and the structure of the SR ring attachment device can be simplified.

Furthermore, in the ring mounting device of the present invention, a large number of SR rings can be supported by the ring holding device installed in the ring supply unit, so that the SR ring can be mounted in one utility pole section. Since the work can be carried out without replenishing the SR ring during the process, it is possible to improve the work efficiency of the SR ring installation.
