Description

  The present invention relates to a peeler that rotates a remote control rod to rotate a stripping tool around an overhead electric wire in a power transmission state to strip the coating.

  2. Description of the Related Art In a live wire operation, a peeler that peels off a coating by remote operation while proceeding in the direction in which an electric wire extends is known. When such a peeler is installed on an electric wire, it is usually carried to a remote electric wire by the remote operation rod in a state of being connected to a remote operation rod for transmitting rotational force. FIG. 9 is a view showing a conventional peeling machine.

  The peeler 101 shown in FIG. 9 includes a support portion 103 that maintains the posture of the main body with respect to the electric wire 108 and a rotating portion 102 that can rotate relative to the support portion 103. The rotating unit 102 is provided with a skinning blade (not shown), and the coating of the electric wire 108 can be peeled off by the rotation of the rotating unit 102.

  A rotational driving force is transmitted to the peeler 101 by a remote control rod or the like (not shown). This remote control bar is connected to an operation bar connecting part 106 provided below the skin peeling device 101. The rotational driving force transmitted from the remote control rod is input from an input shaft protruding inside the operation rod connecting portion 106.

  By the way, as shown in FIG. 9, the center of the rotary shaft of the remote control rod connected to transmit the rotational force to the peeler 101 (same as the center of the input shaft 104) is the center of gravity of the peeler 101. Is out of position. That is, when the peeler 101 is lifted by using the remote control bar as a support bar in a state where the remote control bar can rotate relative to the peeler 101, the peeler 101 rotates around the remote control bar. It becomes easy to do. For this reason, when it moves to the electric wire 108, it will be in an unstable state, and alignment with the electric wire 108 will become difficult, and work efficiency will fall.

  Therefore, apart from the remote control rod that gives the rotational driving force, a support remote control rod for stabilizing the posture of the peeler 101 is required. For this purpose, for example, a remote control rod having an insulating jacket or the like connected to the tip is used, and the peeler is installed on the electric wire while being gripped by the insulating jacket.

  In addition, there exists an example disclosed in patent document 1 about the structure of the above peeling machines.

JP 2008-131844 A

  However, the rotationally driven peeler as described above is generally heavy. Therefore, at the installation stage where workers in high places move in the air, the work becomes unstable and dangerous.

As described above, since the peeler is heavy, in the above-described operation using the support remote control rod separately, a single operator can connect the remote control rod for rotation driving and the remote control rod for support. It is difficult to operate. For this reason, usually, a plurality of workers each have a remote control rod and install them together, but installation work of heavy objects at high places is not easy and requires skill.

  On the other hand, unlike the configuration in which the posture of the peeler is maintained by gripping with an insulating jacket, a configuration in which the remote control rod for rotation driving is locked to the peeler and the rotation is suppressed can be considered. In the structure of locking on the side, it is necessary to release the lock of the peeler at the remote position by remote control after installation on the electric wire, but the work efficiency is lowered because it is difficult to transmit the hand feeling. When the lock mechanism is provided on the remote control rod itself, the structure becomes complicated and the cost increases.

  Therefore, in the peeler of the present invention, the connection state with the existing remote control rod for rotary drive can be locked, and can be installed on the electric wire in a stable state, and can be easily locked without using other tools. An object is to provide a peeler that can be released in a low-cost configuration.

  In order to achieve the above-described object, the skin peeling device of the present invention transmits the rotational driving force by rotating the remote control rod connected through the connecting body, and rotates the skinning blade around the overhead electric wire. A stripping device for remote operation for stripping the coating, wherein the connecting body is composed of a fixed part and a movable part, and the fixed part is provided with an input shaft for inputting the rotational driving force and is movable. The seat is made of a magnetic material at a position where the part can come into contact, and the movable part has a bearing part into which the input shaft is inserted, and a magnet part that can be attached to and detached from the seat part, and an input It has an operating bar connecting part that allows a remote operating bar to be connected coaxially with the shaft, and the input shaft and the movable part can be rotated together around the axis and loosely fitted within a predetermined range in the axial direction. Are connected so as to be in a state, and are provided on the fixed portion side engaging portion provided on the fixed portion and the movable portion. The movable portion side engaging portion is engaged so as to lock the rotation of the movable portion around the input shaft in the contact state of the seating portion and the magnet portion, and the engagement is released in the separated state. And

  If comprised in this way, when a seating part and a magnet part will be in a contact state, since a fixed part side engaging part and a movable part side engaging part lock rotation about the axis | shaft of a movable part, a stick | rod The rotation of the peeler around the axis of the remote control rod connected via the receiving part is suppressed. Further, when the seating portion and the magnet portion are in the separated state, the engagement between the fixed portion side engaging portion and the movable portion side engaging portion is released, so that the movable portion can be rotated about the axis, Thereby, it will be in the state which can rotate a remote control stick | rod with respect to a peeling machine.

  As described above, in the present invention, the peeler is set on the electric wire in a state where the seating part and the magnet part are in contact with each other and the peeler is locked to the remote control rod so as not to rotate and is stable. Can do. Also, by separating the seating part and the magnet part, it is possible to unlock the rotation of the remote control rod with respect to the peeler, so pull the remote control bar against the peeler after setting it on the wire. It is possible to release the lock by separating the seating portion and the magnet portion.

  In addition to the above-described configuration, the skin peeling device of the present invention includes a seating portion and a magnet portion that are each formed on a surface substantially perpendicular to the input shaft, and the movable side engaging portion is located on the seating portion side on the magnet portion. The protrusion is a protruding portion, and the fixed side engaging portion is recessed on the magnet portion side on the seating portion, and is a recess into which the protruding portion can be fitted.

  With this configuration, when the seating portion and the magnet portion are in contact with each other, the protrusion on the magnet portion is inserted into the recess on the seating portion. The rotation of the movable part is suppressed. Further, when the seating portion and the magnet portion are in the separated state, the protrusion is separated from the recess, so that the rotation suppression of the movable portion due to the engagement of the protrusion and the recess is released.

  As described above, in the present invention, the peeler can be locked and unlocked with respect to the remote control rod by a simple structure such as the protrusion and the recess.

  In addition to the above-described configuration, the skin peeling device of the present invention includes a pair of sliding contact members in which a wire sliding contact portion is formed by inner surfaces facing each other and one of the pair of sliding contact members. The two stripping blades that are attached to and slidably contacted with the covered electric wire and project at a predetermined advancing angle and the pair of sliding contact members are parallel to the covered electric wire and are orthogonal to each other. And a pair of clamping members that are magnetically detachably attached to the surface and can be separated from and attached to the mirror surface symmetrically about the covered electric wire.

  If comprised in this way, a pair of sliding contact member will be easily removable with respect to a pair of clamping member. Further, the pair of detachable holding members are accurately attracted to a fixed position, and a good parallel state is always obtained between the covered electric wire to be held and the wire sliding contact portion.

  Thereby, according to the covered electric wire from which a diameter differs, since it can replace | exchange for a pair of sliding contact members which have an appropriate diameter, it can respond flexibly also to the electric wire which has 2 or more types of diameters, and the width | variety of work object Spread. Moreover, since a favorable parallel state is always obtained between the covered electric wire and the electric wire sliding contact portion, friction due to the sliding contact with the covered electric wire can be minimized, and the load on the rotational drive can be reduced.

  In addition to the above configuration, the skin peeling device of the present invention has a through hole formed in at least one of the two attracting surfaces that magnetically attract the pair of sliding contact members in the pair of clamping members. In each of the pair of sliding contact members, a protruding portion that penetrates the through hole and exposes the end portion on the opposite side in the magnetically attracted state with respect to the pair of holding members is formed. On the other hand, a slide claw provided on the holding member that slides in a direction orthogonal to the protruding direction is fixed by engagement.

  If comprised in this way, the shift | offset | difference to the protrusion direction of the protrusion part of the sliding contact member magnetically attracted will be suppressed by the edge part and the slide nail | claw which engages with this, and the direction orthogonal to a protrusion direction The deviation is suppressed by the through hole and the protrusion.

  Thus, magnetic adsorption is greatly reinforced by a simple configuration including at least one pair of protrusions, through holes, and slide claws.

  As described above, according to the skin peeling device of the present invention, the remote control rod is the skin peeling device so that the magnet portion and the seating portion provided in the movable portion and the fixed portion constituting the coupling body are magnetically attracted. When the bolt is pushed to the side, the bolt projecting from the magnet part is inserted into the recessed part recessed in the seating part, so the rotation of the movable part relative to the fixed part, that is, the relative position of the remote control rod relative to the peeler Rotation is suppressed. As a result, it becomes possible to stably install the peeler on the electric wire. Further, at this time, since the peeler can be carried only by the rotary operation remote control bar, it is not necessary to use a separate gripping remote control bar, and the work efficiency is improved.

  And after hooking a stripper on an electric wire, the lock | rock of the movable part with respect to a fixed part can be easily cancelled | released by pulling a remote control stick | toe near. For this reason, it is not necessary to separately provide a remote control rod for unlocking, improving work efficiency and reducing the number of equipment.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
FIG. 1 shows a use state of a peeler in an embodiment of the present invention. The peeler 1 includes a support portion 1a that supports the posture of the main body with respect to the electric wire 8 in a stable state, and a rotating portion 1b that rotates the skinning blade 1c around the electric wire 8. The remote control rod 10 for transmitting the rotational driving force to the rotating part 1b of the skinning device 1 is connected to a connecting body 2 provided on the support part 1a side.

  The support body 1a is provided with a gear body 1e having a U-shaped notch formed at the center thereof. The gear main body 1e can be rotated inside the support 1a, and a rotating portion 1b is connected to a side surface of the gear main body 1e. And this gear main-body part 1e is connected with the bevel-shaped gear part 1d, and can receive the rotational driving force input from the connection body 2. FIG. A tool 12 can be attached to the end on the hand side of the remote control rod shown in the present embodiment. Thereby, a rotational force in the direction around the axis can be easily applied, and the rotating portion 1b can be rotated around the electric wire 8.

  The gear main body 1e has a partial gear 1f attached to one end of the notch on the opening side so as to be swingable. When the peeler 1 is hooked and installed on the electric wire 8, the partial gear 1f is opened. When the remote control rod 10 is rotated after the electric wire 8 is accommodated in the U-shaped notch, the far end is drawn with the rotation of the gear body 1e, and the partial gear 1f is U-shaped. It is arranged in a bridge shape so as to close the opening. Thereby, the state in which the teeth of the partial gear 1f and the teeth on the outer periphery of the gear main body 1e are continuous is formed, and is in a state in which continuous rotation is possible.

  Thus, after becoming a state which can be continuously rotated, the peeling blade 1c of the rotation part 1b is set so that the coating | coated 8b of the electric wire 8 can be peeled off, but detailed description is abbreviate | omitted here. FIG. 1 shows a state where the skinning blade 1c is set, the stripping of the coating 8b proceeds, and the core wire 8a appears.

  Here, as apparent from FIG. 1, the peeler 1 is arranged with the remote control rod 10 biased to a position deviated from the center. For this reason, when the peeler 1 is lifted by the remote control rod 10 and carried to the electric wire 8, the peeler 1 rotates around the axis of the remote control rod 10 unless the rotation of the remote control rod 10 is locked. It moves. Next, the detailed structure of the connection body 2 that connects the remote control rod 10 to the peeler 1 will be described with reference to FIGS.

FIG. 2 is an enlarged view showing a state in which the connector 2 in FIG. 1 is disassembled and viewed from the remote control rod 10 (not shown here) side. FIG. 3 is an enlarged view showing a state in which the coupling body 2 of FIG. 1 is disassembled and viewed from the bevel gear portion 1d side of the peeler 1. FIG.

  As can be seen from FIG. 2, the coupling body 2 includes a fixed portion 4 fixed to the bevel-shaped gear portion 1 d and a movable portion 6 connected to the fixed portion 4. An input shaft 4 a extending from the bevel gear is protruded from the center of the fixed portion 4. The input shaft 4a is formed with a through long hole 4d penetrating in the side surface direction. A disc-shaped seating portion 4b is provided along the side surface of the bevel-shaped gear portion 1d substantially perpendicular to the direction in which the input shaft 4a extends. Further, in the disc-shaped seating portion 4b, concave portions 4c (fixed portion side engaging portions) are formed at two positions across the input shaft 4a.

  On the other hand, the movable part 6 is formed with a through hole into which a set screw 6e can be inserted near the center. And the operation-rod coupling | bond part 6d which can connect the remote control rod 10 is formed. Here, referring to FIG. 3, it can be seen that a bearing portion 6 a into which the input shaft 4 a of the fixed portion 4 can be fitted is formed at the inner center of the movable portion 6. The inner wall surface of the bearing portion 6a is formed in the same hexagonal shape as the input shaft 4a. Thereby, when the movable portion 6 is connected to the fixed portion 4 and the input shaft 4a is fitted into the bearing portion 6a, the input shaft 4a can rotate integrally with the rotation of the movable portion 6. In a state where the movable portion 6 and the fixed portion 4 are connected, the input shaft 4a fitted into the bearing portion 6a is inserted into the through long hole 4d from the outside of the movable portion 6. The tip of the set screw 6e is inserted. Thereby, it is possible to prevent the movable part 6 from being detached from the fixed part 4. Moreover, since the through-hole 4d is formed with a predetermined length margin in the axial direction, the movable part 6 is within a predetermined range in the axial direction even when connected to the fixed part 4. That is, it is in a slidable and slidable state corresponding to the length of the through long hole 4d.

  A magnet portion 6b is provided around the bearing portion 6a of the movable portion 6 so as to be perpendicular to the longitudinal direction of the bearing portion 6a, that is, substantially parallel to the seating portion 4b perpendicular to the input shaft 4a. The magnet portion 6b has six magnet storage portions 6g in which cylindrical magnets can be embedded. FIG. 3 shows an example in which the magnet 6f is embedded and installed in a part thereof. With such a configuration, the number of magnets 6f can be increased / decreased in accordance with the weight of the peeler 1, and the magnetic attractive force can be changed.

  In addition, two bolts 6c (movable part side engaging part, projecting part) are projected from the magnet part 6b. Next, the position of these two bolts 6c in the connection state of the movable part 6 and the fixed part 4 will be described with reference to FIG.

  4A and 4B are cross-sectional views taken along the center of the input shaft 4a. FIG. 4A shows a state in which the movable portion 6 is locked to the fixed portion 4, and FIG. And the unlocked state is shown. In the locked state of FIG. 4A, the magnet portion 6b of the movable portion 6 is seated on the seat portion 4b of the fixed portion 4, and the magnet 6f is magnetically attracted to the surface of the seat portion 4b formed of a magnetic material. It has become. At this time, the bolt 6c on the movable part 6 side is fitted in the recess 4c on the seating part 4b side. And the set screw 6e which is in the insertion long hole 4d of the input shaft 4a has moved to the fixing | fixed part 4 side.

  Thus, since the bolt 6c is fitted in the recess 4c, the rotation of the input shaft 4a around the axis is suppressed. And the magnet 6f adsorb | sucks to the seating part 4b, and the locked state with respect to the fixed part 4 of this movable part 6 is hold | maintained favorably.

  On the other hand, in the unlocked state of FIG. 4B, the magnet portion 6b and the seating portion 4b are in a separated state. At this time, the bolt 6c is detached from the recess 4c. Moreover, the set screw 6e inserted in the through-hole 4d of the input shaft 4a has moved to the remote control rod 10 side.

  In this state, the bolt 6c and the recess 4c are separated from each other, so that the movable portion 6 can freely rotate about the axis with respect to the fixed portion 4.

  That is, when the peeler 1 is carried to the electric wire 8 at a remote position and kept in the state shown in FIG. 4A, the peeler 1 can be prevented from rotating with respect to the remote control rod 10. Therefore, it becomes possible to work in a stable state. Then, when the remote control rod 10 is pulled toward the user in a state where the electric wire 8 is placed in the U-shaped notch of the gear main body 1e of the peeler 1, the magnet adsorbed by the magnet 6f The part 6b can be separated from the seating part 4b, and the lock of the movable part 6 with respect to the fixed part 4 can be easily released. Thereafter, the skinning blade 1c can be set by a conventional operation, and the stripping operation of the coating 8b can be started.

  As described above, according to the peeler in the present embodiment, it can be stably arranged without using a separate remote control rod for support when installing on the electric wire. Moreover, after arrangement | positioning to an electric wire, a lock | rock can be easily cancelled | released only by pulling the remote control rod for a rotation drive forward. In addition, since such a configuration can be used for the existing remote control rod for rotational driving, it can be realized at low cost.

  In the above-described embodiment, the engaging member formed by a combination of a bolt and a concave portion is shown as an example of the movable portion locking mechanism with respect to the fixed portion, but if the engaging structure suppresses rotation around the input shaft, Other configurations may also be used.

  Moreover, in the said embodiment, although the example in which the magnet part and the seating part were formed in the surface substantially perpendicular | vertical with respect to the input shaft was shown, if it is the positional relationship from which both become a contact state in a locked state Other configurations may be used.

(Second Embodiment)
First, the overall structure of the coating stripping tool according to the second embodiment of the present invention will be described with reference to FIG. FIG. 5: is the perspective view shown about the use condition of the peeler using the coating stripping tool which concerns on the 2nd Embodiment of this invention. Here, for convenience of explanation, the illustration of the configuration of a remote control bar or the like for transmitting the rotational driving force is omitted.

  As shown in FIG. 5, the peeler 51 holds the posture with respect to the electric wire 54 in a constant state, and at the same time, the peeling device 51 that rotates around the central axis 54 b of the electric wire 54 and the rotating device 52 that mediates the rotational driving force. It is comprised from the handle 53. FIG. A rotating plate 52a that is rotated by a rotational driving force transmitted from the outside is accommodated in the center of the rotating device 52. A U-shaped notch is formed at the center of the rotating plate 52a, and the rotating plate 52a can be rotated while the electric wire 54 is accommodated. The coating stripper 53 is connected to the rotating plate 52a and can rotate integrally with the rotating plate 52a.

  The coating stripper 53 includes a pair of sliding contact members 55 in which electric wire sliding contact portions are formed by inner surfaces facing each other. The pair of sliding contact members 55 are held on their outer surfaces by a pair of clamping members having a U-shaped cross section cut in a direction perpendicular to the central axis 54b. That is, in the configuration of the pair of sliding contact members 55, the upper sliding contact member 55a positioned on the upper side in the drawing is held by the upper upper clamping member 57a of the configuration of the pair of clamping members 57. . Similarly, on the lower side, the lower sliding contact member 55b is held by the lower holding member 57b. As described above, the upper sliding member 55a and the lower sliding member 55b are in contact with the upper clamping member 57a and the lower clamping member 57b on two outer planes that are parallel to the electric wire 54 and orthogonal to each other. The contact state between the two will be described in detail later with reference to the drawings.

On the side surface of the upper sliding contact member 55a, a window for leading out the coating after peeling is provided, and a skinning blade 59 is provided in this window. The skinning blade 59 is disposed with a predetermined advance angle with respect to the electric wire 54 that is in sliding contact. FIG. 5 shows a state where the coating 54a of the electric wire 54 is peeled off and the core wire 54c appears.

  Next, FIG. 6 shows a state where only the coating stripper 53 is taken out. FIG. 6 shows a state in which the pair of sliding members 55 are separated together with the pair of clamping members 57. As described above, the pinching member 57 and the sliding contact member 55 of the covering stripper 53 according to the present embodiment can be separated from and brought into mirror symmetry about the electric wire 54 by rotating the eye nut 61. Here, the upper and lower sliding members 55a and 55b are held by magnetic attraction to the upper and lower clamping members 57a and 57b, respectively. Details of this configuration are shown in FIG.

  FIG. 7 shows a state in which each of the pair of sliding contact members 55 is separated from the pair of clamping members 57. As can be seen from FIG. 8, the upper sliding member 55a and the lower sliding member 55b have magnets 60 embedded in three locations. In the upper sliding contact member 55a, two magnets 60 are arranged on the side surface facing the upper clamping member 57a and one place in the center of the upper surface. Further, in the lower sliding contact member 55b, two places are arranged on the side surface facing the lower clamping member 57b and one place in the center of the lower surface. And the magnet 60 is embed | buried in the position which can contact | abut the magnet 60 provided in the upper sliding contact member 55a and the lower sliding contact member 55b also on the upper clamping member 57a and the lower clamping member 57b side.

  A protrusion 55d is formed on the upper surface of the upper sliding contact member 55a so as to protrude upward, and a protrusion 55d is formed on the lower surface of the lower sliding contact member 55b so as to protrude downward. Yes.

  On the other hand, through holes 57d are formed at positions of the upper and lower holding members 57a and 57b where the protruding portions 55d of the upper and lower sliding contact members 55a and 55b are arranged in the used state. Thereby, in the attachment state to the clamping member 57 of the sliding contact member 55, the protrusion part 55d is arrange | positioned in the state which penetrated each edge part 55e toward the outer side from the inner side. Here, a groove is formed in the circumferential direction in the end portion 55e exposed from the insertion side to the opposite side by the penetrating protrusion. Then, on the upper surface of the upper clamping member 57a and the lower surface of the lower clamping member 57b, there are provided slide claws 57e that can slide in a direction along the surface, that is, in a direction orthogonal to the protruding direction of the protruding portion 55d. Yes. With such a configuration, the front end of the slide claw 57e can be engaged with the groove formed on the side surface of the end portion 55e, and the position fixing bolt 57f is fastened in the engaged state, whereby the pair of sliding contact members 55 are engaged. Can be fixed to the pair of clamping members 57 in a stable state.

  As described above, according to the covering stripping tool 53 in the present embodiment, the magnet 60 provided on the side surfaces of the sliding contact member 55 and the sandwiching member 57 can be arranged in close contact with the side surface of the sandwiching member 57. Therefore, it is possible to always maintain a parallel state accurately with respect to the central axis 54b of the electric wire 54. For example, when the configuration in which the clamping member 57 is bolted from the outside by bolt fastening and the sliding contact member is bolted is compared with the covering stripping tool according to the present embodiment, the bolt is slightly used. Tolerance is included in the inserted bolt hole. For this reason, it may be slightly tilted and fixed depending on the fastening state. And if it inclines and fixes in this way, a clearance gap will arise between the adsorption | suction surfaces of a sliding contact member and a clamping member, and a favorable parallel state cannot be formed with respect to an electric wire. Compared with this, in the covering stripping tool of this Embodiment, since it is magnetically attracted, a clearance gap does not arise.

Further, since the sliding contact member 55 and the sandwiching member 57 constitute an engaged state by the projecting portion 55d and the slide claw 57e, it is possible to prevent a shift between the two in the direction in which the electric wire 54 extends. Due to the engagement between the groove of the end portion 55e and the slide claw 57e, it is possible to prevent displacement between the two in the vertical direction.

  In addition, as is clear from FIG. 7 described above, in order to fix the pair of sliding contact members 55 to the pair of clamping members 57, a separate fastening member or the like is not required. Accordingly, replacement work is facilitated, and work efficiency is improved. And since the number of parts is small, the burden of parts management is reduced.

  Further, even when a plurality of sets of sliding contact members 55 for replacement are provided according to the electric wires 54 having a plurality of diameters, the magnets 60 are provided on the side surfaces, so that the back-to-back as shown in FIG. Can be absorbed and stored.

  In the peeler shown in FIG. 5 in the above embodiment, a protrusion is formed on each of the pair of sliding contact members, and this protrusion is a through hole formed in the pair of clamping members. As an example, a structure that protrudes through is shown. However, these protrusions and through holes may not be provided.

  Moreover, although the groove | channel was formed in the edge part of the protrusion part in the circumferential direction, the structure which a slide nail | claw engages with this groove | channel was shown as an example, You may employ | adopt the structure of engagement other than this. For example, a configuration in which a slide claw is inserted into a through hole that penetrates the end portion in a direction orthogonal to the protruding direction may be employed.

  Furthermore, although the example in which the through hole is formed only on one surface side among the attracting surfaces that are magnetically attracted to the sliding contact member is shown, the present invention is not limited to this and may be formed on two surfaces.

  Moreover, although the clamping member and the sliding contact member have been shown as an example of a configuration in which a pair of through holes and protrusions are engaged with each other on both the upper and lower sides, the present invention is not limited to this, and a plurality of them may be provided.
