Description

  The present invention relates to a remote insulation operation tool and a remote insulation operation tool using the same, mainly for various insulated indirect hot wire methods such as hot puller work and lead connection work for overhead wires such as high voltage lines and special high voltage lines. The present invention relates to an insulation rod for a remote insulation operation tool that performs the above, and a remote insulation operation tool using the same.

  The following patent documents 1-7 etc. are disclosing as a remote insulation operating tool which can be utilized for such an operation | work. These remote insulation operation tools are equipped with a work tool at the tip, gripping and rotating work tools such as overhead wire support tool, gripper, wire drawing device, draw device, overhead wire spacing dilator, lead wire connection to overhead wire It becomes a long rod-like work implement that can be used to attach equipment such as, and to operate the equipment remotely. Therefore, if an insulating structure is provided between the grip portion, the operation handle, the operation lever and the like on the remote insulation operation rod and the work tool at the tip, safety against electric shock can be achieved.

  However, the remote insulation operation rod described in any patent document also shows an insulation limit position from the work object such as an overhead line, and an umbrella-type insulation limit rod that prevents the gripping hand from exceeding the same position, and this insulation Further away from the outer surface of the remote insulation operation rod, the rainwater that travels from the distal end side of the remote insulation operation rod during work is transmitted to the umbrella-shaped surface that spreads from the outer surface of the remote insulation operation rod. By providing a drainer that drains water at a position, further safety against electric shock is achieved. In addition, the insulation limit rod has the same form as the drainage rod, and exerts the same effect on rainwater that falls along the surface of the remote insulation operation rod.

  In addition, both the insulation limit rod and drainer rod are made of an insulating material such as rubber for the purpose, and are annularly bonded to the outer surface of the remote insulation operation rod, so that rainwater and the like can flow from the top to the bottom. In order to prevent electric shocks from occurring due to rainwater soaking, it is prevented from penetrating.

JP 2000-013943 A JP 2009-050052 A JP 2009-050053 A JP 2009-157321 A JP 2010-082780 A JP 2010-178462 A JP 2010-239839 A

  By the way, rubber insulation limit flaws and drainage flaws have low weather resistance, and change and deteriorate over time, and eventually crack. Cracks allow rainwater to penetrate, causing an electric shock. Therefore, the cracked rubber insulation limit rod and drainer rod have been replaced, and the long-distance remote insulation operation rod has been used.

  However, cracked insulation limit rods and draining rods can be separated from the remote insulation operation rod by cutting off appropriate numbers even if they are annular, but to reattach the new insulation limit rod and drainage rod to the remote insulation operation rod. , For example, it is essential to disconnect or remove the attachment from an obstacle such as the work tool at the tip, and it is also necessary to reconnect and reattach them after replacement, which takes time and effort. .

  The present invention has been made in view of the above-described problems, and it is an object of the present invention to provide a remote insulation operation tool cage and a remote insulation operation tool using the same, which can be easily remounted at the time of replacement without changing the equipment. And

  In order to solve the above-described problems, an insulating rod of a remote insulation operation tool according to the present invention includes a cylinder portion attached with adhesion to the outer surface of a remote insulation operation rod, and an obliquely downward outward from the cylinder portion to an umbrella shape. A draining skirt portion extending toward the outside, and in an insulating rod having an inner periphery of the cylindrical portion as an adhesive surface to the outer surface of the remote insulating operation rod, the cylindrical portion and the draining skirt portion are separated at appropriate locations in the circumferential direction. It is characterized in that the end faces facing each other at the cut-off portion are mutually bonded surfaces.

  In such a configuration, if there are a plurality of separation parts, the cylinders are formed in an annular shape along the outer periphery of the remote insulation operation rod from the direction perpendicular to the axis so as to bring the divided parts together. In addition, even if the separation part is a single continuous body, if the separation part is elastically opened by fitting the remote insulation replacement rod from the direction perpendicular to the axis and then elastically restoring it, An annular form can be formed along the outer surface along the cylindrical portion.

  Therefore, in any case, if the adhesive is applied to the inner peripheral adhesive surface of the cylindrical portion and the adhesive surface facing each other at the separating portion, the cylindrical portion and the draining skirt portion are integrated into an annular shape. It can be set as the mounting state which adhered the part to the outer surface of the remote insulation operating rod.

  In the above description, the separation can be made by a path bent in the thickness direction.

  In such a configuration, in addition to the above, the separation path that is bent from the outer surface to the inner surface of the cylindrical portion and the draining skirt portion causes the partial adhesion peeling to cause the rain water to penetrate from the outside. However, it is possible to prevent the remote insulation operation rod from reaching the outer surface by making the route a labyrinth or extending beyond the thickness.

  In the above, the separation path further has a crank-shaped portion from the outer surface toward the inner surface side, and is a separation path entrance between the first bent portion and the second bent portion from the outer surface, and the path outer surface side is the inner surface of the path It can be a tongue-shaped lid piece that is thinner than the side.

  In such a configuration, in addition to the above, since the tongue-like lid piece is thin, the tongue-shaped lid piece is adhered to the inner surface of the path at the path entrance with good adaptability, and does not react independently even when subjected to external force. It can be absorbed by the elastic action integrated with the inner part of the meat path.

  In the above, the separation part can be thicker than the other part in the circumferential direction in both the cylindrical part and the draining skirt part.

  In such a configuration, in addition to the above, since the separation portion is thicker than the other portions in the circumferential direction in the cylindrical portion and the draining skirt portion, the separation path length is proportional to the thickness increase. It can be increased and the deformation strength is also increased.

  In the above, further, axial reinforcing ribs may be formed from the distal end side to the base portion at a plurality of circumferential positions on the inner periphery of the draining skirt portion.

  In such a configuration, in addition to the above, the draining skirt portion is subjected to an external force due to overhanging from the outer surface of the remote insulation operation rod, repeatedly undergoes elastic deformation and restoration, and its deformation base portion is susceptible to stress. The amount of elastic deformation can be suppressed by the reinforcing ribs oriented in the axial direction, and as a result, the necessary restoration amount can be suppressed.

  In the above, the cylindrical portion may further have an annular groove formed on the inner periphery thereof, the groove being fitted to a positioning convex provided on the outer surface of the remote insulating operation rod.

  In such a configuration, an appropriate number of places in the circumferential direction are cut off, and the cylindrical part and the draining skirt part are continuous in the axial direction. By aligning the annular recess on the inner periphery of the cylindrical portion with the annular projection on the outer surface of the remote insulation operating rod, axial alignment at the disconnecting portion is performed. Moreover, the installation position as an insulation limit rod or a draining rod can be positioned for each remote insulation operation rod of the insulation rod.

  Remote insulation operation characterized in that any one of the above-mentioned insulation rods uses an insulation rod attached to the outer surface of the remote insulation operation rod on the inner surface with adhesion as an insulation limit rod or draining rod. Also provide ingredients.

  According to the insulating rod of the present invention, the separated parts are separated from each other around the outer surface of the remote insulation operation rod, and the continuous body is elastically opened and fitted around the outer surface of the remote insulation operation rod to be restored. Even if there are other fittings on the outer surface of the remote insulation operation rod, the cylinder part can be placed from the direction perpendicular to the axis without being obstructed, and the separation part is adhered, and the inner surface of the cylinder part is adhered to the outer surface of the remote insulation operation rod. It can be mounted as an integral annular body, and it can be easily replaced in a short time because it is made of rubber and is weather resistant. Between the separation part and the outer surface of the remote insulation operation rod, it does not become a path for rainwater soaking, and functions as an insulation limit bottle or drainer.

  In addition to the above, the separation path from the outer surface to the inner surface of the cylindrical portion and the draining skirt portion is a labyrinth due to its bent form and extension beyond the thickness, so that rainwater should be removed during partial adhesion peeling. Even if it causes a penetration from the outside, it is possible to suppress reaching the outer surface of the remote insulation operation rod, and to reduce the probability of penetration from between the inner surface of the cylinder portion and the outer surface of the remote insulation operation rod.

  In addition to the above, the thin tongue-like lid piece formed at the entrance of the separation path at the crank-shaped portion from the outer surface of the separation path is made thin so that it adheres well to the inner surface of the path at the path entrance. Thus, even if an external force is applied, it is absorbed by an elastic action integrated with a thick path inner portion without reacting independently, and the adhesion at the path entrance is prevented from being peeled off, thereby improving durability.

  In addition to the above, the separation part is thicker than the other parts in the circumferential direction for both the cylinder part and the draining skirt part, and it is easy to prevent the rainwater from penetrating into the inner surface by increasing the separation path length. The increase in deformation strength makes it difficult for the adhesive to peel off and improves durability.

  In addition to the above, the draining skirt part repeats elastic deformation and restoration under external force and is susceptible to stress at the base of this deformation, but the deformation amount and necessary restoration amount are combined by the reinforcing ribs facing in the axial direction. Since it is suppressed, durability can be improved.

  In addition to the above, in order to attach a circumferential continuum or divided body to the outer surface of the remote insulation operation rod, which is separated from a suitable number of places in the circumferential direction, an annular recess on the inner circumference of the cylinder portion is remotely insulated. By fitting with the annular ridge on the outer surface of the operating rod, axial alignment at the cut-off portion is made, so that it can be mounted neatly without discrepancies. In addition, since the installation position as the insulation limit rod or draining rod is positioned for each remote insulation operation rod of the insulation rod, the installation position can be optimized without special measurement.

The above object, other objects, features, and advantages of the present invention will become more apparent from the following description of the best mode for carrying out the invention with reference to the drawings.

  The insulation rod according to the embodiment of the present invention and the remote insulation operation tool using the same will be described in detail with reference to FIGS. 1 to 3 to provide an understanding of the present invention. The following description is a specific example of the present invention and does not limit the matters described in the claims.

  As shown in the example shown in FIG. 1, FIG. 2, and FIG. 3, the insulating rod of the present embodiment includes a cylindrical portion 1 that is attached to the outer surface of the remote insulating operation rod 100 with adhesion, and the cylindrical portion 1. And a draining skirt portion 2 extending obliquely downward outward from the umbrella shape, and has a basic configuration in which the inner periphery of the cylindrical portion 1 is an adhesive surface 3 to the outer surface of the remote insulating operation rod 100. The cylindrical portion 1 and the draining skirt portion 2 are at appropriate locations in the circumferential direction, such as one location on the insulation rod 200 of the example shown in FIG. 1 and two locations on the insulation rod 300 of the example shown in FIGS. Are separated from each other, and the end surfaces facing each other at the separation portion 4 are used as the bonding surfaces.

  If there are a plurality of separating parts 4 as shown in FIG. 2 and FIG. 3, the divided parts 300 a and 300 a divided into two parts are brought together so that they are perpendicular to the outer periphery of the remote insulation operation rod 100. Annular form is formed along the tube part 1 from the direction. Moreover, even if the separating part 4 is one continuous body 200a like the insulating rod 200 shown in FIG. 1, after the separating part 4 is elastically opened, the remote insulating operating rod 100 is fitted from the direction perpendicular to the axis. If elastically restored, the tubular portion 1 can be placed along the outer surface of the remote insulating operation rod 100 to form an annular shape.

  In this way, in any case, that is, if the adhesive is applied to the inner peripheral adhesive surface 3 of the cylindrical portion 1 and the adhesive surface 5 facing each other at the disconnecting portion 4 regardless of the number of disconnected portions, The tube portion 1 and the draining skirt portion 2 can be integrated into an annular shape so that the tube portion 1 is attached to the outer surface of the remote insulating operation rod 100.

  Accordingly, the separated bodies 300a are separated from each other around the outer surface of the remote insulating operation rod 100 in the direction of arrow A shown in FIGS. 2 (c), 3 (a), and 3 (b). 1 is elastically opened and fitted around the outer surface of the remote insulation operation rod 100 and restored as shown in FIG. The cylindrical part 1 can be set along the right angle. With the adhesion of the separation part 4 and the adhesion of the inner surface of the cylindrical part 1 to the outer surface of the remote insulation operation rod 100, as shown in FIG. As a rubber product, it can be easily replaced in a short period of time due to weather resistance. Between the separation part 4 and the outer surface of the remote insulation operation rod 100, there is no path for rainwater to penetrate, and functions as an insulation limit bottle or a drainer bottle.

  Separation is exemplified by the insulating rod 300 of FIGS. 2 and 3, and can be performed by the separation path 11 bent in the thickness direction as indicated by a virtual line in FIG. 2C. In this way, even if the separation path 11 bent from the outer surface to the inner surface of the cylindrical portion 1 and the draining skirt portion 2 causes the partial adhesion peeling to cause the rain water to penetrate from the outside, the separation path 11. It is possible to prevent the remote insulating operation rod 100 from reaching the outer surface by forming a labyrinth and extending beyond the thickness.

  Therefore, the separation path 11 from the outer surface to the inner surface of the cylindrical portion 1 and the draining skirt portion 2 is a labyrinth due to its bent form and an extension exceeding the thickness, so that it is necessary to remove the rainwater from the outside when it is partially peeled off. Therefore, even if it causes a soaking through, it can be prevented from reaching the outer surface of the remote insulation operating rod 100, and the probability of the penetration from the space between the inner surface of the cylinder part 1 and the outer surface of the remote insulating operating rod 100 can be reduced. .

2 and 3 has a crank-type portion 11a from the outer surface toward the inner surface, and the crank-type portion 11a includes the first bent portion 11b and the second bent portion from the outer surface. 11d has a separation path entrance 11d.
The separation path 11 includes a tongue-shaped lid piece 300c that comes into contact with the crank-type portion 11a.
The tongue-shaped lid piece 300c is formed such that the path outer surface side has a thinner tongue shape than the path inner surface side 300b, and the path outer surface side of the tongue-shaped lid piece 300c and the path outer surface side of the crank-type portion 11a are in contact with each other.

  The tongue-shaped lid piece 300c formed in this way is thin, so that it adheres well to the inner surface of the path at the path entrance 11d, and does not respond independently even when an external force is applied. It can be absorbed by the elastic action integrated with the part. Such elastic absorption of external force prevents the adhesion of the path entrance 11d from being peeled off, so that the durability is improved.

  In addition, the separating portion 4 of the insulating rod 300 in FIGS. 2 and 3 is set to t2 which is thicker than the thickness t1 of other portions in the circumferential direction in both the cylindrical portion 1 and the draining skirt portion 2. As described above, the separation portion 4 is thicker than the other portions in the circumferential direction in the cylindrical portion 1 and the draining skirt portion 2, thereby increasing the length of the separation path 11 in proportion to the thickness increase. The deformation strength is also increased. By increasing the length of the separation path, it is easy to prevent the rainwater from penetrating from the outer surface to the inner surface, and by increasing the deformation strength, the peeling of the adhesive hardly occurs and the durability is improved.

  The dowels 12 for connection are integrally formed at a plurality of axial positions on one side of the adhesive surfaces 5 facing each other of the separating portion 4, and the dowel holes 13 for connection fitting with the dowels 12 are formed in the recesses on the other side. It is formed in a shape. By connecting the dowel 12 and the dowel hole 13 via an adhesive to connect the separating portion 4 by adhesion, it is possible to prevent surface slippage at the separating portion 4 and increase the adhesive strength. It is possible to avoid misalignment and poor adhesion due to this, and improve durability.

  Further, reinforcing ribs 14 in the axial direction as shown in FIG. 2 are formed from a distal end side toward the base portion 15 at a plurality of circumferential positions on the inner periphery of the draining skirt portion 2. The draining skirt portion 2 is subjected to an external force from the outer surface of the remote insulation operation rod 100 and repeatedly undergoes elastic deformation and restoration, and the deformation base 15 is susceptible to stress and is reinforced in the axial direction. The amount of elastic deformation is suppressed by the ribs 14, and as a result, the required amount of restoration is also suppressed and the durability is improved.

  Further, the cylindrical portion 1 of the insulating rod 200 of FIG. 1 and the insulating rod 300 of FIG. 2 and FIG. 3 has a positioning ridge as shown in FIG. 1 provided annularly on the outer surface of the remote insulating operation rod 100. A concave line 16 that fits in 101 is formed in an annular shape. In order to attach the circumferential continuum 200a and the split body 300a to the outer surface of the remote insulation operation rod 100, the cylinder portion 1 and the draining skirt portion 2 are continuous in the axial direction after the appropriate number of places in the circumferential direction are cut off. By fitting the annular recess 16 on the inner periphery of the cylindrical portion 1 with the annular positioning projection 101 on the outer surface of the remote insulating operation rod 100, the axial alignment at the separating portion 4 is performed. In addition, the mounting position as an insulation limit rod or a draining rod can be positioned for each remote insulation operation rod 100 of the insulation rods 200 and 300.

  As a result, in order to mount the circumferential continuum 200a and the divided body 300a, which are separated at appropriate locations in the circumferential direction, on the outer surface of the remote insulating operation rod 100, the annular recess 16 on the inner circumference of the cylindrical portion 1 is By fitting with the annular positioning ridge 101 on the outer surface of the remote insulation operating rod 100, the axial alignment at the separating portion 4 is performed, so that it can be mounted neatly without any discrepancy. In addition, since the installation position as an insulation limit rod or drainage rod is positioned for each remote insulation operation rod 100 of the insulation rods 200, 300, the insulation position distance varies depending on the difference in transmission voltage without special measurement. Can respond appropriately.

  The insulating rods 200 and 300 as described above are attached to the outer surface of the remote insulating operation rod 100 on the inner surface by bonding the separating portion 4 and attached as an insulating limit rod or a draining rod with remote insulation as shown in FIG. An operating rod 400 is also provided.

  The remote insulation operation rod 400 is made of an insulating member such as FRP, and is safe against electric shock between the operation destination and the hand side. However, since the insulation rods 200 and 300 are also made of an insulation material such as rubber, the positioning projection 101 It is preferable to use a highly rigid material such as metal or resin and screw it to the outer surface of the remote insulating operation rod 100 to give priority to positioning strength and durability. Adhesives such as epoxy that are conventionally used may be used, but the insulating rods 200 and 300 are not slid in the axial direction on the outer surface of the remote insulating operation rod 100 but attached in a predetermined position. Therefore, even a bonding having a so-called instantaneous bonding function can be applied without any problem.

  Further, as the remote insulation operation rod 100, a tool provided with a rotating tool for fastening and releasing a nut or bolt at the tip, a tool provided with a gripping tool such as a yatco, a tool provided with a hook, or other work tools are used. The present invention is applied to various known operations such as those provided.

Even if it exists, the cylinder part 501 can be made to follow along the axis perpendicular direction without being disturbed.

The separation part 824 may be formed by shifting the position of the cylindrical part 801 and the draining skirt part 802 as shown in FIG.
Further, as shown in FIG. 14, the separating portion 824 may be inserted.
14 includes a first divided body 920 and a second divided body 922 that are separated from each other by a separating portion 924, and a tubular portion 901 and a draining skirt portion 902 are separated from each other. . The 1st division body 920 and the 2nd division body 922 are continued by the thin part. Each of the first divided body 920 and the second divided body 922 has a joint portion 905 formed to be thin in the thickness direction.

By inserting the first joining surface 905 </ b> A of the first divided body 920 and the second joining surface 905 </ b> B of the second divided body 922, the flange 900 is integrated into an annular shape.

Insulating rod 500, which is an integral annular body, as shown in FIG. 12, with bonding of joining surface 505 of separation portion 504 and bonding of bonding surface 503 of the inner surface of cylindrical portion 501 to the outer surface of remote insulating operation rod 100. In addition, it can be installed as a continuous insulating rod 800, and can be easily replaced in a short time due to the weathering life as a conventional rubber.
Between the separation part 504 and the outer surface of the remote insulation operation rod 100, it does not become a path through which rainwater permeates, and functions as an insulation limit bottle or drainer bottle.

  As shown in FIG. 4, the insulation rod 500 is separated by forming a joining surface 505 bent in the thickness direction. In this way, even if the joining surface 505 constituting the separation path bent from the outer surface to the inner surface of the cylindrical portion 501 and the draining skirt portion 502 causes partial adhesion peeling and causes rain water to penetrate from the outside, Due to the unevenness of the joint surface 505 of the separation path and the extension of the adhesion area exceeding the thickness, it is possible to prevent rainwater from reaching the outer surface of the remote insulating operation rod 100.

  Therefore, the joining surface 505 constituting the separation path from the outer surface to the inner surface of the cylindrical portion 501 and the draining skirt portion 502 is a part of the concavity and convexity due to the bending form and the extension of the joining area exceeding the thickness. Even if it causes the rain water to permeate from the outside at the time of typical adhesion peeling, the rain water is prevented from reaching the outer surface of the remote insulation operation rod 100, and the inner surface of the cylindrical portion 501 and the outer surface of the remote insulation operation rod 100 are prevented. The probability of penetrating downward from the space can be reduced.

  In addition, the disconnecting portion 504 is also increased in deformation strength by the joining concave 507 and the joining convex 509 in the cylindrical portion 501 and the draining skirt portion 502. By increasing the length of the joining surface 505 of the separation path, it is easy to prevent the rainwater from penetrating from the outer surface to the inner surface, and by increasing the deformation strength, it is difficult to cause peeling of the adhesive, and durability can be improved.

  A connecting dowel 12 is integrally formed at one of the opposing joining surfaces 505 of the separating portion 504 at a plurality of locations separated in the axial direction, and the other joining surface 505 is fitted to the dowel 12. The dowel hole 13 is formed in a concave shape. By connecting the dowel 12 and the dowel hole 13 via an adhesive to connect the separating portion 504 by adhesion, surface slippage at the separating portion 504 can be prevented and the adhesive strength can be increased. The displacement between the first divided body 600 and the second divided body 700 and the adhesion failure caused thereby can be avoided, and the durability can be enhanced.

  Furthermore, reinforcing ribs 14 extending in the axial direction as shown in FIG. 11 may be formed at a plurality of circumferential positions on the inner periphery of the draining skirt portion 502 from the distal end side toward the base portion 15. With this configuration, the draining skirt portion 502 receives an external force from the outer surface of the remote insulating operation rod 100 and repeatedly undergoes elastic deformation and restoration, and the deformation base 15 is likely to be stressed. The amount of elastic deformation can be suppressed by the reinforcing ribs 14 oriented in the axial direction, and as a result, the required amount of restoration is also suppressed and the durability is improved.

In addition, the cylindrical portion 501 of the insulating rod 500 has a positioning groove 656 and a positioning groove 756 that fit on a positioning protrusion 1101 as shown in FIG. 10 provided in an annular shape on the outer surface of the remote insulating operation rod 100 on the inner periphery thereof. Is formed in an annular shape. The positioning recess 656 is provided on the inner peripheral surface of the cylindrical portion 501 so as to be recessed in a direction intersecting the axis. The positioning recess 656 is formed continuously from the first joint surface 605A to the second joint surface 605B in the horizontal direction.
An appropriate number of places are cut off in the circumferential direction of the insulating rod 500, and the first divided body 600 and the second divided body 700, in which the cylindrical portion 501 and the draining skirt portion 502 are continuous in the axial direction, are connected to the remote insulating operation rod 100. When the annular positioning recess 656 on the inner periphery of the cylindrical portion 501 is fitted to the annular positioning projection 1101 on the outer surface of the remote insulating operation rod 100 when mounted on the outer surface, the joint surface 505 of the disconnecting portion 504 has a shaft. Alignment in the direction is made. In addition, the mounting position as an insulation limit rod or a draining rod can be positioned for each remote insulation operation rod 100 of the insulation rod 500.

  As a result, when attaching the first divided body 600 and the second divided body 700 having the circumferential direction, which are separated at appropriate positions in the circumferential direction of the insulating rod 500, to the outer surface of the remote insulating operation rod 100, the cylinder By fitting the annular positioning groove 656 on the inner periphery of the portion 501 with the annular positioning protrusion 1101 on the outer surface of the remote insulation operating rod 100, the axial alignment at the separating portion 504 is made, so there is no discrepancy. Can be worn neatly. In addition, the installation position as an insulation limit rod or drainage rod is positioned for each remote insulation operation rod 100 of the insulation rod 500, so the installation position is appropriate for different insulation limit distances depending on the transmission voltage, etc. without special measurement. It can correspond to.

  The insulating rod 500 as described above is bonded to the joint surface 505 of the separating portion 504, and attached to the outer surface of the remote insulating operation rod 100 with adhesion as an insulating limit rod or a draining rod on the inner surface of the cylindrical portion 501. A proximal-side remote insulation operation rod 1001 and a proximal-side remote insulation operation rod 1003 as shown in FIG. 12 can be provided.

  The remote insulation operation tool 1000 according to the present embodiment includes three types of base-side remote insulation operation rods 1001 and base-side remote insulation operation rods 1003, and any base-side remote insulation operation rod 1001 and base-side remote insulation. One kind of distal-side remote insulation operation rod 1005 that can be detachably attached to the distal end of the operation rod 1003 and two kinds of tools 1006 and 1007 that are detachably attached to the distal end of the distal-side remote insulation operation rod 1005. It consists of and.

As shown in FIGS. 10A and 10B, the distal-side remote insulation operation rod 1005 is an FRP insulation pipe 1009 having a sufficient length to provide an insulation safety distance between the worker and the work piece during remote operation. It consists mainly of A tool attachment 1010 for fixing the tool 1006 and the tool 1007 is provided at the tip. At the base end, a fixture 1011 to be fixed to both the base end side remote insulation operation rod 1001 and the base end side remote insulation operation rod 1003 is provided.
An insulating rod 500 according to the present invention that functions as a drain rod 1004 and a limit rod 1008 is attached to an intermediate portion of the insulating pipe 1009.

The limit rod 1008 is fitted and fixed at the intermediate portion of the remote insulating operation rod 100 in order to clarify the boundary between the portion that the person may hold and the other portion in order to prevent an electric shock accident.
The draining rod 1004 is fitted and fixed to the intermediate portion between the lower portion of the grip portion and the upper portion of the limit rod 1008 as a measure against rainfall.

Note that the proximal remote insulation operating rod 1001, the proximal remote insulation operating rod 1003, and the distal remote insulation operating rod 1005 are made of an insulating member such as FRP, and safety against electric shock between the operation destination and the hand side is achieved. Since the insulating rod 500 is also made of an insulating material such as rubber, the positioning protrusion 101 is made of a highly rigid material such as metal or resin, and the insulating rod 500 is screwed to the outer surface of the remote insulating operation rod 100. Therefore, it is preferable to give priority to positioning strength and durability.
An adhesive such as an epoxy-based adhesive may be used, but the insulating rod 500 is attached to the outer surface of the remote insulation operation rod 100 in the axial direction rather than sliding in the axial direction and attached in a predetermined position. Therefore, even bonding with a so-called instantaneous bonding function can be applied without any problem.
