Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a tool for working on overhead power lines installed on utility poles, etc. (Prior art) For example, when working on live wires such as overhead power lines, the distribution lines to be worked on are located in the air. A work tool is attached to the tip, etc., and the work tool is operated remotely. When using this type of work tool, it is necessary to perform the desired work in an appropriate posture relative to the power distribution line, and for convenience in moving the work tool, it is required that the weight be light. Conventionally, in this type of work tool,
It is designed to perform only specified operations (for example, stripping wires, compressing connection sleeves, etc.) at the position where the working tool is set on the distribution line.
(Problem to be Solved by the Invention) However, even if a work tool is designed to be lightweight based on such consideration, it cannot be positioned accurately at a predetermined work position on an overhead power line and in a predetermined posture. Working with overhead power lines is a tedious and inefficient task, and requires considerable skill to perform the task properly. In particular, when machining operations are performed multiple times with the same work tool at close positions in the same work area, it is troublesome as it is necessary to newly position the work tool for each machining operation. It is. This invention was made based on the above circumstances, and aims to improve the work efficiency of overhead power line work by efficiently bringing a working tool to a predetermined work position on the overhead power line. It is. (Means for Solving the Problems) In order to achieve this object, the present invention provides a tool for working on overhead electric wires that is attached to the tip of a support means and used so as to face the overhead electric wires. The apparatus is provided with a processing section for processing the wire, and a feeding device for moving the processing section in a direction parallel to the overhead wire gripped by the wire gripping section. (Function) According to the present invention, when machining is performed multiple times at close positions in the working area of an overhead electric wire, the working tool attached to the tip of the support member is set once at a predetermined working position on the overhead electric wire. Then, by operating the feeding device,
Since the machining part can be moved along the overhead wire while maintaining the appropriate condition, the troublesome work of having to reposition the work tool to a predetermined position on the overhead wire during subsequent machining can be omitted. This can improve work efficiency when working with live overhead power lines. (Example) This invention will be explained below with reference to an example shown in the drawings.
The following embodiment is applied to a distribution line as an overhead electric line, and the first embodiment will be explained first with reference to FIGS. 1 to 11. The work tool of this embodiment is a stripping tool 1 for removing the covering of a power distribution line W installed on a utility pole, and a manibrator M (in accordance with the present invention) mounted on a packet of an aerial work vehicle (not shown).

That is, the screw shaft l4 and the guide rod 15 are equipped with a skin peeling machine 17 (which will be described later) that is operated by hydraulic pressure (corresponding to the processing section in the present invention), and by the rotational drive of the screw shaft 14, The position can be adjusted freely along the guide rod 15. Note that a long hole 16 is formed in the bottom plate 2 between the threaded shaft 14 and the guide rod 15 in parallel thereto, and this long hole 16 is connected to the cover 18 of the hydraulic passage connected to the peeling machine 17. This is an insertion hole so as not to obstruct the sliding movement of the peeling machine 17. A slit 22 is formed in the central part of the end of the bottom plate 2 toward the stripping device part 3 in the kamura guide part 5 formed on the outside of the wire guide 12 (on the left side in FIG. 1). be. This slit 22 is used to engage a cam roller 31 (described later) with its guide groove 32 (see Fig. 7), and in order to make this engagement smooth, the entrance portion of the slit 22 is widened. be. The wire gripping portion 9 of the stripping tool 1 is configured as shown in FIGS. 8 and 9, and the stripping machine 17 is configured as shown in FIGS. 10 and 1, for example.
It is configured as shown in Figure 1. That is, the wire gripping section 9 has a pedestal 9a fixed on the substrate 6, and a gripping block 9b movable in a direction perpendicular to the power distribution line W is installed on the pedestal 9a to face it. Rack teeth 9c are formed on each of these gripping blocks 9b. These rack teeth 9c are respectively meshed with spur gears pivotally supported on the pedestal 9a, and these gears are connected to the bevel gear 8 so as to interlock with each other. Therefore, these gripping blocks 9b are driven alongside each other by the rotational driving force supplied from the drive shaft 7a, and the power distribution line W is positioned between these gripping blocks 9b, so that the gripping blocks 9b can be gripped. It is. Further, as shown in FIGS. 10 and 11, the peeling machine 17 includes a base 23 that is movably configured to be fitted onto the screw shaft 14 and the guide rod l5, and is supported on the base 23. a slide base 24 disposed perpendicularly to the screw shaft 14, etc., and this slide base 24;
A pair of peeled parts 25a, 25 supported so as to be able to come alongside
It has b. Then, these peeled parts 25a. Semi-cylindrical recesses 26a and 26b are formed on the side surface of contact side of 25b, respectively, and cuts are provided on the surfaces of these recesses 28a and 28b to remove the coating of the power distribution ljiIW captured here. Blade 2 7 a. 2 7 b is installed. When hydraulic pressure is supplied through the coupler l8, the peeling parts 25a and 25b are driven toward each other by this hydraulic pressure.
The power distribution line W is held in the recesses 2 6 a and 2 6 b, and then a cutting blade drive mechanism (not shown in detail) is driven by hydraulic pressure to cut the coating of the power distribution line W. When this machining work is completed and the hydraulic pressure is removed,
The operation of the cutting blades 27a and 27b is stopped, and the peeling section 25
a and 25b are spaced apart from each other at both ends of the slide base 24 to open recesses 26a and 28b. The stripping tool 1 constructed in this manner is used by holding the tip of the tool with a manibrator M on a distribution line W equipped with a wire tensioner (hereinafter referred to as Shimera) 30, as shown in FIG. The Shimera 30 is used to maintain the distribution line W under tension during live-line work on the distribution line W, and has an insulated wire 33, and the tip of the wire 33 is A kamura 31, which is a wire gripping tool for gripping the electric wire W, is attached.A winding drum (not shown) is provided on the other end side of the wire 33, and this winding drum is used as a temporary support for the telephone pole. It is attached to the arm and winds up the wire 33 with the handle.
The wire 33 can be locked at any length. As shown in FIGS. 5 and 6, the camcorder 31 attached to the tip of the wire 33 has a wire gripping groove 36 extending in the direction in which the wire 33 extends on one side of the upper part of the main body 35. A lever 38 whose one end is pivotally supported by a pivot 37 is installed on the lower surface of the wire gripping groove 36, and a gripping member 3 having an inner surface of the groove is disposed at the tip of the lever 38.
9 is installed. Guide grooves 32 are formed on both lower side surfaces of the wire gripping groove 36 in a direction substantially parallel to the wire gripping groove 36. B1 These guide grooves 32 engage with the kamura guide part 5 of the peeling tool 1 as described above, and are shaped into a wide shape on the side where the wire 33 extends to prevent the engagement between the two. Care has been taken to ensure that the process is carried out smoothly. When the wire W is stretched using the shimera 30 having the camra 31 having such a configuration, the peeling tool 1 supported by the mani break M is used as follows (
Mainly, see Figure 7>. Attach the above-mentioned stripping tool 1 to the tip of the manibrator M, operate the manibrator M to position the stripping tool 1 near the camshaft 31, and connect the power distribution line W to the wire guide 11, 12 of the stripping tool L and the open state. The peeling tool 1 is placed on the electric wire gripping part 9, and the manibrator M is operated along the power distribution line W to move the stripping tool 1 to the kamura 31 side. Along with this, the kamura guide part 5 of the peeling tool 1 is fitted into the guide groove 32 of the kamura 31 attached to the power distribution line W, so if the kamura 3l is installed in advance at an appropriate position for the work, , the stripping tool 1 can be positioned at an appropriate position with respect to the distribution line W with the camla 31 positioned at the innermost part of the camla guide part 5. After this, by closing the electric wire grip part 9, the distribution line W can be removed. Fix it to the peeling tool 1. As a result, the stripping tool 1 is engaged with and supported by the camshaft 31 at one end, and is fixed by the wire gripping section 9 at the other end, making it difficult for the posture of the stripping tool 1 to change, allowing proper stripping. I can do the work. If there is another stripping work shed near the part of the distribution line W where the stripping work has been performed, the stripping tool 1 is moved along the distribution line W by the feeding device aP. ．． Therefore, when moving the peeling machine 17 from the area where the skin was first peeled to the area where the skin will be peeled next,
There is no need to move the mani break M, and the next stripping work can be carried out without having to re-capture and hold the distribution line W, resulting in good work efficiency. After the stripping work at the required locations, open the wire gripping section 9 of the stripping tool 1, and remove the stripping tool 1 from the distribution line W by operating the manibrator M to remove the camla guide section 5 from the camla 31. The skinning work is completed. As explained above, in this embodiment, the distribution line W
Since a feeding device P is provided to move the peeling machine 17 along the "a."
When machining is to be carried out several times, once the stripping tool 1 is set on the power distribution line W, subsequent machining can be carried out without operating the manipulator M by operating the feeder MP. Further, since the peeling tool 1 is formed with a camla guide portion 5 and the camla 31 is formed with a guide groove 32, the peeling tool 1 is fitted and supported by the camla 3l, and the posture of the peeling tool 1 is This has the advantage of making it more stable and making it easier for the peeling tool 1 to operate properly. In addition, in the embodiment described above, a case has been described in which a manibrator type robot is used to perform the required work, but the present invention is not limited to this, and the present invention is not limited to this, and the present invention is not limited to this. It goes without saying that the same method can be used when carrying out the following. Next, a second embodiment shown in FIGS. 12 to 14 will be described. This embodiment is the same as the first embodiment described above except that the camshaft guide 42 is designed to be replaceable. In the following explanation, only two of these differences will be explained, and the same reference numbers will be given to the drawings for the overlapping parts, and the explanation will be omitted. That is, in this second embodiment, the bottom plate 2 extends up to the wire guide 12 at the end of the stripping device section 3, and below the wire guide 12 there is a holder 41 made of channel material disposed opposite to it. is fixed by welding. This holder 41 has a separate kamura guide 42 which is plate-shaped and has a slit 22 in the center in the width direction.
is removably attached with a lock bin 43. This is because if the work to be done with the work tool is, for example, inserting and connecting electric wires into a sleeve, the long kamura guide 42 is required due to the nature of the connection work, but when the work is cutting electric wires, This design takes into account the fact that even if it is short, it still functions well; on the other hand, if it is not long, care must be taken when handling the tool when moving it. By making the kamura guide 42 removable in this way, by preparing in advance multiple types of kamura guides 42 with different lengths while keeping the dimension in the width direction constant, it is possible to select the appropriate one according to the work with the work tool. There is an advantage that the length of the kamura guide 42 can be selected and used, and there is no problem in handling the work tool due to the kamura guide 42 being too long. Next, a third embodiment shown in FIGS. 15 to 18 will be explained. In this example, the first example described above is as follows:
The only difference is that the drive section 4, the peeling device section 3, the kamura guide section 5, etc. are constructed separately, and the rest are the same. In the following explanation, only these different points will be explained, and the same reference numbers will be given to the overlapping parts in the drawings, and the explanation will be omitted. That is, in this third embodiment, the electric wire guide 11 is provided upright at the end of the substrate 6, and the holder 45 made of channel material is welded to the lower side of the electric wire guide 11, which is arranged to face each other. It is fixed. The end of the bottom plate 2 of the working tool is inserted into the holder 45 and held therein, and the edge 2a of the bottom plate 2 is raised along the side surface of the wire guide 11, and the guide rod 15 is inserted into the holder 45. A bearing part 46 and a joint part 47 that removably connects and bears the bevel gear 13 and screw shaft 14 are formed. Therefore, this drive section 4 and other parts can be disassembled and assembled by attaching and detaching the lock bin 48. This is because it is necessary to use tools for this type of work depending on the content of the live wire work to be done, and in practice, the various work tools necessary for the work are loaded in advance in the packet of the aerial work vehicle. This is done in consideration of reducing the weight of the loaded load. Since the work tool is configured such that the drive unit 4 and the other parts can be connected separately, when working on a live power distribution line while riding in an aerial work vehicle, the drive unit 4 can be connected separately! W on the packet of the aerial work vehicle! This eliminates the need for packets to be loaded, which reduces the loading load, and has the advantage of increasing work efficiency by making packets more stable and easier to operate. Next, a fourth embodiment shown in FIGS. 19 to 21 will be described. This embodiment is the same as the first embodiment described above except that the peeling machine 17, which is a processing section, is configured to be replaceable. In the following explanation, only this difference will be explained. Duplicate parts will be given the same reference numbers in the drawings and their explanation will be omitted. That is, in this fourth embodiment, base 2
3 is formed into a frame shape, and a slide base 2 is attached to this base 23.
4 is removably fixed and supported by a lock bin 51. Therefore, by removing the lock bin 51 and removing the cover 18 of the hydraulic circuit, the peeler 17 can be removed from the base 23 (see imaginary line in FIG. If the shape of the fitting part is formed in advance, it is possible to perform other types of live wire work by using the driving part 4 and the feeding device P as well. Similarly to the third embodiment, when the work tool is mounted on the packet of the aerial work vehicle, there is an advantage that the work efficiency is increased by reducing the mounted load. Although the present invention is shown applied to a power distribution line as an overhead electric wire, the present invention is not limited to this, and can be similarly applied to signal lines installed on utility poles, etc. (Effects of the invention) Since the invention is configured as described above, when machining is performed multiple times at close positions in the working area of an overhead electric wire, the working tool attached to the tip of the support member is used to carry out the predetermined work on the overhead electric wire. Once set in position, by operating the feed device, the machining section can be moved along the overhead wire while maintaining an appropriate condition. It is possible to omit the troublesome work of directing the wires to a predetermined position, and it is possible to improve the work efficiency of live wire work on overhead power lines.
