Description

  The present invention relates to a tip connecting tool for a remote control rod that is connected to the tip of a remote control rod and is used for a purpose of attaching a general-purpose attachment device such as a connection clamp device or an electric wire gripper to a wire or the like mainly by remote control. The present invention relates to a remote operation mounting method using this tool.

  Conventionally, electrical work such as wiring work for overhead wires is often performed in a live line state where power is supplied to a high-voltage wire that is an existing overhead wire. This is because if the wiring work is performed in a state where the power supply side circuit of the high-voltage line for performing the electrical installation work is cut off, a wide range of power consumers will be affected by the power failure during the work. Such electrical installation work is generally performed in the following procedure. That is, first, after cutting a required portion of the covered electric wire wired in the air, electrically connect one end of the bypass lead cable provided with a switch to one of the blackout side covered electric wires separated by the cutting. While connecting, the other end side of the lead cable is connected to the connection clamp device in an electrically connected state. Subsequently, the connection clamp device is attached to the separated live wire side of the separated live wire by remote control using a remote control rod from the ground or on the work vehicle. At this time, the connection clamp device is attached in a state of electrically connecting the lead cable to the core wire of the covered electric wire. As a result, the lead cable bypasses by electrically connecting both of the covered power wires on the power failure side and the live wire side.

  For the convenience of explanation for facilitating understanding of the operation of attaching the connection clamp device to the covered wire by remote control using a remote control rod, refer to FIG. 2 and FIG. 4 showing an embodiment of the present invention. While explaining. In FIG. 4, the end of the lead cable 30 is attached to the contact terminal 24 which is a needle-like electrode part at the connection terminal part 29 of this connection clamp part 29 in the electrical connection state. A general-purpose joint member 33 in which an engagement slit 37 is formed in a headed cylindrical body is provided at the lower end portion of the connection clamp device. The engagement slit 37 includes a vertical groove 37a extending from the end opening along the axis of the joint member 33, a horizontal groove 37b extending from the upper end of the vertical groove 37a in the circumferential direction of the joint member 33, and the horizontal groove. A stop-end groove 37c extending from the end of 37b toward the end along the axial direction of the joint member 33 is formed continuously. On the other hand, as shown in FIG. 2, the distal end connecting tool 1 includes an engaging shaft 13 portion having a diameter to be slidably inserted into the engaging slit 37 in the device side connecting portion 10 connected to the connecting clamp device. And a slider 14 that is always urged in the protruding direction by the compression coil spring 17 so as to freely enter and exit.

  When the connection clamp device is attached to the live wire side covered electric wire and the lead cable 30 is electrically connected to the core wire of the covered electric wire, first, the engaging shaft 13 of the tip connecting tool 1 is inserted into the engaging slit 37. Then, while sliding as shown by the arrow in FIG. 4, it is fitted into the toe groove 37c. At this time, the slider 14 comes into contact with the top plate portion (not shown) of the joint member 33 and then is immersed in the instrument side connecting portion 10 while compressing the compression coil spring 17, so that the engagement shaft 13 is compressed. The compression coil spring 17 is held in the toe groove 37 c by the restoring force of the compression coil spring 17. Thereby, the connection clamp device is attached to the distal end of the remote control rod 2 via the distal end connecting tool 1. In this state, after the connection clamp device is lifted up to the connection position of the lead cable 30 by the remote control rod 2, the covered electric wire is fitted into the wire holding groove 28a of the connection clamp device by remote operation by the remote operation rod 2, and subsequently Then, by rotating the remote control rod 2 to raise the contact blade 28 of the connection clamp device, the contact blade 28 is brought into contact with the core wire through the insulation coating material of the covered electric wire, and the contact blade 28 and the core wire are brought into contact with each other. Get electrical continuity. Thereby, the connection clamp device is attached to the covered electric wire in a state where the lead cable 30 is electrically connected to the core wire.

  When the attachment of the connection clamp device is completed as described above, the remote control rod 2 is operated in the reverse procedure to that described above to remove the engagement shaft 13 from the engagement slit 37. The tip connecting tool 1 is removed from the connection clamping device. As a result, the lead cable 30 is in a state of being bypassed by electrically connecting both the insulated wires on the power failure side and the live wire side to each other. .

  However, the conventional tip connection tool is supported while maintaining the connection with the connection clamp device by holding the engagement shaft 13 in the stop groove 37 c in the engagement slit 37 by the restoring force of the compression coil spring 17. There is only. Therefore, when performing the operation of attaching the connection clamp device to the covered electric wire by remote operation with the remote control rod 2, since the connection clamp device is supported by the tip connection tool in an unstable state, the operation is not easy. There is a problem that takes time and labor. Further, when attaching the heavy fixture 3 to the tip connection tool, when the fixture 3 is slightly lowered by its own amount, the engagement shaft 13 comes out of the stop groove 37c of the engagement slit 37. As a result, the support of the connection clamp device becomes more unstable, and sometimes the connection clamp device falls off the electric wire.

  In order to solve the above problem, it is conceivable to set the spring force of the compression coil spring 17 strongly. In such a case, after attaching the connection clamp device to the electric wire, the tip connection tool is connected to the connection clamp device. When removing the engagement shaft 13 from the toe groove 37c, not only a large push-up operation force is required to compress the compression coil spring 17 having a strong spring force but also the large push-up force is maintained. Since it is necessary to rotate the remote control rod 2 and displace the engagement shaft 13 to the end of the vertical groove 37a via the horizontal groove 37b, the removal operation becomes difficult. Moreover, since the tip connection tool is rotated by the remote control rod 2 while the tip connection tool is pressed against the connection clamp device with a large push-up force, the connection clamp device rotates together with the tip connection tool, and the connection clamp device is attached to the electric wire. The force is loosened, and the connection state of the connection clamp device to the electric wire becomes unstable.

  The present invention has been made in view of the above-described conventional problems, and can provide a tip connecting tool that can stably and reliably support a mounted device and can be easily removed from the mounted device without requiring a large operating force. An object of the present invention is to provide an attachment method capable of stably and reliably attaching an attached device to an electric wire or the like using a tip connecting tool.

  In order to achieve the above object, the tip connecting tool of the remote control rod according to the first aspect of the present invention is connected to the tip of the remote control rod, and the attached tool is detachably attached to the outer peripheral surface. A tool base portion having a thread groove formed thereon, a fixing screw projecting outwardly and screwed into the screw groove, and continuously provided at one end of the tool base portion. On the other hand, an operating rod side connecting portion connected to the tip of the tool base portion, and a tool side connected to the other end side of the tool base portion and rotatably fitted in the joint member of the attached tool. A connecting portion; and an engaging shaft that protrudes from an outer surface of the instrument side connecting portion and engages / disengages with an engaging slit in which a vertical groove, a horizontal groove, and a toe groove are formed in the joint member, By fastening the fixing screw, the fixing screw and the engaging shaft It said sandwiching the Yointo member is characterized by fixing the object to be attached instrument.

  The remote operation mounting method using the tip connection tool of the invention according to claim 2 is a remote operation by using the tip connection tool of the invention according to claim 1 to remotely attach the mounted tool to an attachment object such as an electric wire using a remote control rod. A remote operation mounting method for mounting, the step of connecting the operation rod side connection portion of the tip connection tool to the tip of the remote control rod so as to be integrally rotatable, and the device side connection portion of the tip connection tool being attached The fitting screw is inserted into the joint member of the instrument and the engaging shaft of the instrument-side connecting portion is inserted into the toe groove of the engaging slit of the attached instrument, and then the fixing screw is rotated by the operation shaft. A step of clamping the joint member between the engagement shaft and the fixing screw to fix the attached tool to the tip connecting tool by pressing against the end of the member and fastening; Yo The fixing device is loosened by lifting the mounting device and attaching the mounting device to the mounting object by rotating the remote control rod, and hitting the operation shaft of the fixing screw with the rod-shaped body. Thereafter, the method further comprises a step of removing the tip connecting tool from the attachment tool by removing the engagement shaft from the engagement slit by remote operation of the remote control rod.

  According to the first aspect of the present invention, the engaging shaft of the tip connecting tool attached to the tip of the remote control rod is inserted into the toe groove through the vertical groove and the horizontal shaft of the engaging slit of the joint member in the attached device. When the fitting tool is temporarily fixed, the fixing screw is rotated by the operating shaft and is tightened into the press contact state with the lower end surface of the joint member, the joint member of the mounting tool is engaged with the engaging shaft and the fixing screw. Since the attached device can be stably connected in a firm connection state without wobbling with respect to the tip connecting tool, even when attaching a heavy attached device, It can be attached to the tip connecting tool in a state where it can be reliably and stably supported. Therefore, when attaching a fixture to a covered wire by remote control using a remote control rod, the remote operation for the attachment can be easily performed. The instrument can be attached in a stable state without falling off the wire. In addition, when removing the tip connection tool from the attachment tool, the connection lock state between the tip connection tool and the attachment tool can be released by loosening the fixing screw with the operation rod, so that a large operating force is not required. The shaft can be easily removed from the engagement slit and removed.

  According to the second aspect of the present invention, after the attachment tool is attached to the attachment object, when the tip connection tool is removed from the attachment tool, the operation shaft of the tip connection tool is a rod-like body in the direction in which the fixing screw is loosened. If the operation is performed so that the fixing screw is loosened, the connection lock state between the tip connection tool and the mounted device can be released, so the remote control bar is operated to move the engagement shaft from the toe groove of the engagement slit. By pulling out from the vertical groove through the horizontal groove, the tip connecting tool can be easily removed from the mounted device.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, exemplary embodiments of the invention will be described with reference to the drawings. 1 and 2 are a plan view and a front view showing a tip connecting tool 1 according to an embodiment of the present invention. This tip connecting tool 1 is connected to the tip of a remote control rod 2 which will be described later in FIG. 3 and used for attaching to a covered electric wire while supporting an attached tool 3 which will be described later in FIG. The tip connecting tool 1 is connected to a tool base portion 4 having a thread groove 7 formed on the outer peripheral surface of a cylindrical outer body, and a stopper portion 8 interposed at one end (lower end in the figure) of the tool base portion 4. An operating rod side connecting portion 6 provided, a connecting plug 9 provided in the operating rod side connecting portion 6, and an operating shaft 12 projecting from both sides in the radial direction so that the internal thread portion (see FIG. (Not shown) are screwed together, the tool side connecting part 10 connected to the other end (upper end in the figure) of the tool base part 4, and the tool side connecting part 10 projecting from both radial sides. And an engagement shaft 13, a slider 14 provided at the other end portion (upper end portion in the drawing) of the instrument side connecting portion 10, and a compression coil spring 17 that urges the slider 14 in the protruding direction. Configured. The slider 14 is normally held in a state in which the stopper pin 18 is in contact with the inner surface of the outer body of the appliance side connecting portion 10 by the urging force of the compression coil spring 17.

  This tip connecting tool 1 is used by being connected to the tip of a remote control rod 2 shown in FIG. Since the remote control rod 2 is a well-known one, it will be briefly described. The remote control rod 2 takes the form of a rod formed of an electrically insulating material as a whole, and a rotary operation unit 19 provided at the lower end and an operator with one hand. The grip part 20 for gripping with the grip part 20, the collar part 21 provided at the upper end of the grip part 20, and the rain cover 22 provided at the intermediate part between the collar part 21 and the tip. The rotation operation unit 19 is equipped with a torque limiter (not shown) whose rotation amount is preset, and a rotating member that rotates integrally with the rotation operation unit 19 is accommodated in the remote control rod 2. Has been.

  When connecting the tip connection tool 1 to the tip of the remote control rod 2, the operation rod side connection portion 6 of the tip connection tool 1 is inserted from the upper end opening of the remote control rod 2, and is shown by a two-dot chain line in FIG. As described above, when the upper end surface of the remote control rod 2 is brought into contact with the stopper portion 8 of the tip connecting tool 1, the rotating member built in the remote control rod 2 is connected to the connection plug 9 so as to be integrally rotatable. The tip connecting tool 1 is attached to the tip of the remote control rod 2. In this connected state, when the rotation operation portion 19 of the remote control rod 2 is rotated in any direction, the entire tip connection tool 1 is integrally rotated in the rotation operation direction.

  Then, the to-be-attached tool 3 attached to the front-end | tip connection tool 1 is demonstrated. A variety of attachment devices 3 are to be attached to the tip connection tool 1, but in this embodiment, as the attachment device 3, a lead cable for bypass wire is electrically connected to a covered wire on the live wire side. A connection clamping device used for mechanical mounting in a state is illustrated. As shown in FIG. 4, the mounted device 3 made of this connection clamp device has a contact blade 24 that penetrates an insulating coating material of a coated wire, which will be described later, at a lower portion of the clamp body 23 having a substantially C shape. The movable contact stand 27 equipped with is arranged. The contact blade 24 has a triangular prism shape with a regular triangular cross section. An electric wire holding portion 28 is provided on the upper portion of the clamp body 23 so as to face the contact blade 24. The electric wire holding portion 28 has a semicircular portion having a diameter substantially equal to the diameter of the covered electric wire to be held. A substantially U-shaped electric wire holding groove 28a having the shape is formed. The electric wire holding groove 28a has a shape that can be securely held so that the covered electric wire does not move by being in surface contact with the outer peripheral surface of the covered electric wire fitted into the electric wire holding groove 28a.

  The movable contact base 27 is integrally formed with a connection terminal portion 29 extending obliquely downward from one end portion thereof (the right end portion in FIG. 4), and the end of the bypass lead cable 30 is connected to the connection terminal portion 29. The part is attached in an electrically connected state. Thus, the lead cable 30 is electrically connected to the contact blade 24 through the internal wiring of the movable contact base 27 by being attached to the connection terminal portion 29.

  A head portion of a screw shaft 31 screwed into a screw hole 23a in a lower end base portion of the clamp main body 23 is rotatably connected to the bottom portion of the movable contact base 27. On the other hand, the clamp body 23 is provided with a slide guide portion 23b extending in parallel with the screw shaft 31. The slide guide portion 23b extends from the other end portion (left end portion in FIG. 4) of the movable contact base 27. The engaged arm portion 32 is slidably engaged. Thereby, when the screw shaft 31 is rotated, the movable contact base 27 is moved in the vertical direction of the drawing along the slide guide portion 23b without rotating, so that the contact blade 24 is moved into the electric wire holding groove 28a. On the other hand, it is moved in the approaching direction or the separating direction.

  The lower end portion of the screw shaft 31 is fixed by a fixing screw 34 to a joint member 33 whose main body portion is a headed cylindrical shape. An engagement slit 37 into which the engagement shaft 13 is inserted and removed is formed in the headed cylindrical main body portion of the joint member 33. The engagement slit 37 has a width slightly larger than the diameter of the engagement shaft 13 and extends from the lower end along the axis of the joint member 33, and from the upper end of the vertical groove 37a to the joint member 33. A horizontal groove 37b extending in the circumferential direction and a stop groove 37c extending downward in parallel with the vertical groove 37a from the groove end of the horizontal groove 37b are continuously formed. As shown in FIG. 2, the tip connecting tool 1 has two engaging shafts 13 projecting from both sides in the radial direction of the instrument side connecting portion 10, and accordingly, The joint member 33 of the attachment device 3 is also formed with engagement slits 37 having the same shape as shown in FIG.

  Next, a method for attaching the attachment tool 3 to the covered electric wire by remote control using the remote control rod 2 connecting the tip connection tool 1 to the tip will be described. First, when the operating rod side connecting portion 6 of the tip connecting tool 1 is inserted into the remote operating rod 2 from the upper end opening, the upper end surface of the remote operating rod 2 is brought into contact with the stopper portion 8 of the operating rod side connecting portion 6. The rotary member built in the remote control rod 2 is connected to the connection plug 9 so as to be integrally rotatable, thereby connecting the tip connecting tool 1 to the tip of the remote control rod 2 as shown in FIG.

  Subsequently, on the ground, as indicated by an arrow in FIG. 4, the engagement shaft 13 of the distal end connecting tool 1 attached to the distal end of the remote control rod 2 is set to be perpendicular to the engagement slit 37 of the joint member 33 in the attached device 3. While being inserted along the groove 37a, the instrument side connecting portion 10 is fitted into the joint member 33, and after the engagement shaft 13 reaches the upper end of the vertical groove 37a, it is moved so as to move along the horizontal groove 37b. When the mounting tool 3 or the tip connecting tool 1 is relatively rotated and the engaging shaft 13 reaches the left end of the horizontal groove 37b, the operating force for inserting the tip connecting tool 1 into the joint member 33 is loosened. While the compression coil spring 17 is being compressed, the slider 14 immersed in the instrument side connection part 10 receives a force protruding from the instrument side connection part 10 by the restoring force of the compression coil spring 17, and the engagement shaft 13 is Toe groove After being automatically pushed into 7c, it is held in this state. Thereby, as shown in FIG. 5, the attached device 3 is temporarily fixed to the tip connecting tool 1.

  In the state where the fixture 3 is temporarily fixed, by rotating the fixing screw 11 with the operation shaft 12, the fixing screw 11 is screwed upward along the screw shaft 31, as shown in FIG. Then, the joint member 33 is fastened to the lower end surface in a pressure contact state. Therefore, the lower part of the joint member 33 is sandwiched from above and below by the engagement shaft 13 and the fixing screw 11 so that the attached device 3 is stably connected to the tip connection tool 1 in a strong connection state without fear of wobbling. Therefore, even if the attached device 3 is heavy, the attached device 3 can be attached to the tip connecting tool 1 in a state where it can be reliably and stably supported.

  As described above, when the attached tool 3 is attached to the distal end of the remote control rod 2 via the tip connection tool 1, the remote control rod 2 is lifted, and as shown in FIG. The remote control rod 2 is operated and hooked on the covered electric wire 39 so that the covered electric wire 39 to be connected to the lead cable 30 connected to the connection terminal portion 29 is inserted into the holding groove 28a. Subsequently, when the rotary operation unit 19 at the lower end of the remote control rod 2 shown in FIG. 3 is gripped and rotated in the forward direction, this rotation is converted into a rotating member, a tip connecting tool, and a mounted object accommodated in the remote control rod 2. It is transmitted to the screw shaft 31 via the joint member 33 of the instrument 3. Therefore, the screw shaft 31 is moved relative to the clamp body 23 in a relative direction protruding upward from the screw hole 23a, so that the movable contact base 27 on which the upper end of the screw shaft 31 is rotatably supported rises. Then, the contact blade 24 advances toward the covered electric wire 39.

  Then, as shown in FIG. 6, the cutting edge of the contact blade 24 is cut into the insulating covering material 39b of the covered electric wire 39, and eventually comes into contact with the core wire 39a and becomes electrically conductive. At this time, the rotation operation unit 19 of the remote control rod 2 is rotated and tightened until the torque limiter built in the remote operation rod 2 makes a clicking sound, so that reliable electrical conduction between the contact blade 24 and the core wire 39a is achieved. Can be obtained. As a result, the lead cable 30 having one end connected in advance to the power cut-side covered wire is connected to the live wire-side covered wire 39 at the other end, so the lead cable 30 is cut and separated on both sides. It becomes a bypass line which connects 39 mutually.

  Subsequently, when the tip connecting tool 1 is removed from the attachment tool 3, as shown in FIG. 6, one of the operation shafts 12 of the tip connecting tool 1 is hit with a rod-like body 40 in the direction in which the fixing screw 11 is loosened. Thus, the operation of hitting the two operation shafts 12 alternately with the rod-like body in the same direction is repeated. As a result, as shown in FIG. 7, the fixing screw 11 is loosened, and the connection lock state between the tip connection tool 1 and the attached device 3 is released. Subsequently, as shown in FIG. 8, when the remote control rod 2 is operated and the engagement shaft 13 is extracted from the stop groove 37 c of the engagement slit 37 through the horizontal groove 37 b from the vertical groove 37 a, The tool 1 is detached from the mounted device 3. At the time of this detachment operation, the spring force of the compression coil spring 17 of FIG. 2 acts so as to hold the engagement shaft 13 in the stop groove 37c. The tip connecting tool 1 is a compression coil like a conventional tool. Unlike the structure in which the attached device 3 is held by the spring force of the spring 17, the attached device 3 is firmly connected and supported by fastening of the fixing screw 11, so that the compression coil spring 17 is a weak spring. It is set to force, and it can be easily removed without requiring a large operation force in the operation of removing the tip connecting tool 1 from the attached device 3.

  The tip connecting tool 1 of the above embodiment is inexpensive by modifying the existing tip connecting tool by forming the screw groove 7 in the tool base portion 4 and screwing the fixing screw 11 into the screw groove 7. Can be produced. For this reason, in the above embodiment, the case where the compression coil spring 17 and the slider 14 of the existing tip connecting tool remain as they are is illustrated. However, the compression coil spring 17 and the slider 14 are covered by fastening of the fixing screw 11. Since the fixture 3 can be firmly connected and supported, it can be excluded. If excluded, the cost can be reduced with the simplification of the configuration, and the spring force does not act when the engagement shaft 13 is engaged with or disengaged from the engagement slit 37. There is an advantage that the operation of attaching and detaching the tip connecting tool 1 to the attached device 3 becomes easier.

  In the above embodiment, the case where the connection clamp device having the contact blade 24 is used as the attachment device 3 has been described as an example. However, the tip connecting tool 1 of the present invention uses the insulating coating material 39b of the covered electric wire 39. It is also applied to the case where a connection clamp device, a wire gripper, or the like of a type that obtains electrical conduction by sandwiching a fixed die and a movable die on a core wire 39a that has been peeled off by a predetermined length and used as a target of an attached device be able to. However, in that case, it is a condition that the attached devices include a general-purpose joint member 33 having an engagement slit 37 in which a vertical groove 37a, a horizontal groove 37b, and a stop groove 37c are continuously formed. Become. In addition, the engagement slit 37 can be formed in a substantially T shape having a pair of vertical grooves 37a, horizontal grooves 37b, and toe grooves 37c, as shown by a two-dot chain line in FIG. In this case, there is an advantage that the direction of rotation when the tip connecting tool 1 or the attached device 3 is relatively rotated is arbitrary.

  In the present invention, after the engagement shaft is fitted into the engagement slit of the joint member in the mounted device and the mounted device is temporarily fixed, the fixing screw is rotated by the operation shaft and is pressed against the lower end surface of the joint member. By tightening the joint member, the joint member of the attached device is sandwiched between the engagement shaft and the fixing screw, and the attached device can be stably connected in a strong coupled state without fear of wobbling. Even when attaching a large attachment device, the attachment device can be attached in a state where it can be reliably and stably supported, and when removing it from the attachment device, by loosening the fixing screw with the operation rod, Since the connection lock state between the tip connection tool and the mounted device can be released, the engagement shaft can be removed from the engagement slit without requiring a large operating force. It is possible to provide a distal end connecting tool a marked effect can be removed by pulling out the.
