Description

  The present invention relates to a polisher, and more particularly, to a tool that easily polishes an object at a remote location.

  Conventionally, when connecting a disconnected electric wire, the sheath of the electric wire is peeled off, and after the core wire of the electric wire is polished, a connection sleeve is sheathed on the core wire and compression connected to make a conductive connection It is carried out.

  When this electric wire is connected to a power pole, it is necessary to work in a remote position, and when a power failure cannot be made, it is necessary to work with an insulating operation rod or the like.

As a tool for connecting electric wires using this type of insulation operation rod, the electric wire skin is devised so that the electric wire can be removed from the opening on one end side, and the electric wire can be stripped and the core wire polished at the same time. There is a peeling device (see, for example, Patent Documents 1 to 3).
JP-A-8-163730 Japanese Patent Laid-Open No. 10-14046 Japanese Patent Laid-Open No. 11-332048

  In such a conventional electric wire skinning device, the electric wire inlet is opened in a cylindrical shape, and in the case of a hard material such as a power line, it is less likely to be bent. Then, it is possible to remove the coating of the electric wire and polish the core wire without problems by inserting from the insertion port.

  However, in the case of an electric wire that is easily bent, such as a pull-down line connected to the power line, the electric wire may be bent to such an extent that it cannot be inserted into the insertion port of the skinning device without any problem.

  In such a case, the electric wire is gripped by the YATCO 203 by attaching the electric wire brush 201 to the tip of the insulation operating rod 202 as shown in FIG. It is necessary to polish the core D of D.

  However, since the electric wire brush 201 is rubbed and pressed while pressing the peripheral surface of the core d of the electric wire D from the side, as shown in FIG. There is a possibility that it will be bent and cannot be inserted into the connecting sleeve (exposed to the core d of the electric wire D). When the core d of the electric wire D is bent, as shown in FIG. 10 (b), it is necessary to make a correction so as to be straight, and the electric wire D can be connected efficiently. I can't.

  Moreover, not only the core wire d of such an electric wire D but a case where it is necessary to perform various operations accompanied by a polishing operation without deforming an object at a remote position, for example, without deforming a plate-like member or a small piece electrode. There is also.

  Therefore, the present invention makes it possible to polish a remote position object without deforming it by making a remote work tool available, and in particular, to polish without deforming the core of the electric wire. An object of the present invention is to provide a polisher capable of facilitating wire connection work and the like.

  1st invention of the polisher which solves the said subject WHEREIN: The holding | grip which hold | grips so that a pair of rotation member may rotate relatively centering on a rotating shaft, and a front-end | tip part may contact | connect, and it may pinch | interpose a target object , An operation unit that operates to rotate the rotation member of the gripping unit, and a gripping unit that is connected to a position separated from the operation unit to transmit an operation force applied to the operation unit to the gripping unit A polishing device comprising a pair of attachments each having a transmission portion and attached to the distal end of the rotating member of the remote working tool, the mounting tool being attached to the distal end of the rotating member of the remote working tool It has an attachment part which attaches so that attachment or detachment is possible, and a polish member provided in the opposing surface of the attachment part attached to the tip part of a rotation member, and can be contacted / separated.

  According to the present invention, the remote work tool is configured to relatively rotate the rotation member of the gripping part by sandwiching the object by transmitting the operation force from the remote operation part separated from the work object via the transmission part. The tip part can be brought close to the tip part, and the attachment part of the mounting tool is attached to each of the tip part, and the object is sandwiched by the polishing member on the opposite surface of the tip part (attachment part). Can be made. Therefore, by using a remote work tool, it is possible to polish the object by sliding the polishing member while sandwiching the object without applying a force from one direction to the object and bending it.

  In addition to the specific matter of the first invention, the second invention of the polisher that solves the above problem is that the polishing member of the mounting tool is a brush in which wires are densely planted on the opposing surfaces of the mounting portions. It is comprised by these.

  In this invention, it can polish by pinching | interposing a target object with the brush (polish member) of the opposing surface of the attaching part attached to the front-end | tip of a remote work tool. Therefore, the residue etc. remaining on the surface of the object can be effectively peeled off by the brush wire and polished.

  In addition to the specific matter of the second invention, the third invention of the polisher that solves the above-mentioned problem is that the wire of the polishing member of the wearing tool is refracted into the shape of “<”, and the “ It is planted in the opposing surface of each attaching part so that the refraction direction of "<" may become opposite.

  In this invention, the object can be sandwiched and polished by a brush (a polishing member) in which a wire rod refracted in a “<” shape is planted on the opposite surface of the attachment portion attached to the tip of the remote work tool. Accordingly, the refracting wire rod can be restored without falling down on the “K” shape of the brush, and the “K” shape is set in the opposite direction so as to be in pressure contact with each other. However, it is less likely that the other side will be brought down by meshing without falling down in the same direction, and the residue remaining on the polished surface of the object can be effectively hooked and peeled off by the tip of the wire of the brush.

  In addition to the specific matters of any of the first to third inventions, the fourth invention of the polisher that solves the above-mentioned problems is characterized in that the attachment part of the mounting tool is disposed between the polishing member and the polishing member. An elastic member that enables tilting is interposed.

  In this invention, when the object is sandwiched by the polishing member of the mounting portion attached to the tip of the remote work tool, the polishing member is made by the elastic force of the elastic member so as to face in parallel with the surface of the object. Can be tilted. Therefore, the polishing member can be brought into sliding contact with the surface of the object with an equal pressure, and the entire surface of the object can be effectively polished by the entire surface of the polishing member.

  In addition to the specific matters of any of the first to fourth inventions, the fifth invention of the polisher that solves the above-mentioned problems is characterized in that the polishing member of the wearing tool is from the tip of the rotating member to which the attachment portion is attached. Is also extended to the rotating shaft side of the rotating member, and the rotating end of the member that fixes the polishing member abuts against each other when approaching each other to start the rotation of the polishing member. A moving fulcrum is provided.

  In this invention, when the object is sandwiched by the polishing member of the mounting portion attached to the distal end of the remote work tool, the extended end of the front side of the polishing member (the rotary shaft side of the rotary member of the remote work tool) When the rotation fulcrums of the parts abut, the polishing members rotate around the rotation fulcrum so as to face each other in a parallel state. Therefore, when the object is a thin object or a wire, the entire surface of the polishing member can be brought into contact with each other with equal pressure, and the object can be polished more effectively on the entire surface of the polishing member. .

  As described above, according to the present invention, by attaching the mounting tool to the tip of the rotating member of the gripping portion of the remote work tool, the object can be sandwiched and pressed by the polishing member at the tip, and the object can be pressed. The polishing member can be slid in contact with the object in a state of sandwiching the object without being bent by applying force from the direction. Therefore, for example, in the case of a core wire of an electric wire, the polishing member in a state of sandwiching the core wire can be slidably contacted and polished by rotating around the periphery.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described with reference to the drawings. 1-6 is a figure which shows 1st Embodiment of the polisher based on this invention.

  In FIGS. 1 and 2, the polishers 10 and 20 are designed to have a structure that can be attached to the gripping part 110 located on the distal end side of the yatco (remote work tool) 100 shown in FIG. 4, and are attached to the yatco 100. In this state, it is possible to perform an operation of polishing an object at a remote position.

  First, as shown in FIG. 4, the YATCO 100 includes a gripping unit 110 that grips an object such as various parts and materials, an operation unit 120 that inputs an operation (force) of the gripping unit 110, and the gripping unit 110. And a support transmission unit 130 that is coupled to a position at which the operation unit 120 is separated by a support bar 131 and that transmits an operation performed by an operator input to the operation unit 120 to the gripping unit 110 by a transmission bar 132. This Yatco 100 is generally made of an insulating material such as a plastic or rubber material to ensure insulation.

  The holding part 110 is formed in an arc shape and is fixed to one end side of the support rod 131 of the support transmission part 130, and is similarly formed in an arc shape and one end of the transmission bar 132 of the support transmission part 130. And a movable member 112 that is pivotally supported around a rotation shaft 113 that is connected to the stationary member 111 and disposed on the stationary member 111 (support bar 131) side. The grip 110 is formed between the rotating shaft 113 by moving the stationary member 111 and the movable member 112 relative to each other about the rotating shaft 113 to bring the tip portions 111a and 112a into contact with and away from each other. It is constructed so that the object can be grasped and grasped in the space formed or between the tip portions 111a and 112a thereof. That is, the stationary member 111 and the movable member 112 of the grip part 110 of the YATCO 100 constitute a rotating member that relatively rotates.

  The operation unit 120 includes a fixture 121 attached to the other end side of the support rod 131 of the support transmission unit 130, and a lever whose one end side is pivotally supported by a rotary shaft 121a disposed in the fixture 121. One end side is pivotally supported on the handle 122 and the rotation shaft 121a of the fixture 121 so as to be coaxial with the lever handle 122, and the other end side is relatively rotatable via the rotation shaft 123a. The connecting lever 123 connected to the transmission rod 132 of the support transmission portion 130, and the rotation of the lever handle 122 is transmitted to the transmission rod 132 of the support transmission portion 130 via the connection lever 123, and the transmission rod 132 is shown in FIG. 4, the rotating shaft 121a of the fixture 121 so as to be biased upward (in the direction in which the distal end portions 111a and 112a of the immovable member 111 and the movable member 112 are separated from each other). A spring material (not shown) are disposed, and is made of.

  Accordingly, when the operator grips and supports the support bar 131 of the support transmission unit 130 and rotates the lever handle 122 of the operation unit 120 in the direction in which the operator approaches the support bar 131, the YATCO 100 transmits the support transmission. When the transmission rod 132 of the portion 130 is pulled downward in FIG. 4 and the movable member 112 of the gripping portion 110 is rotated in the direction approaching the immovable member 111, the tip portions 111a and 112a can be brought closer to each other. The object can be grasped and grasped. On the other hand, when the lever handle 122 is released and the operating force via the transmission rod 132 is released, the transmission rod 132 is pushed upward in FIG. 4 by the elastic force of the spring material, and the movable member 112 does not move. By rotating in a direction away from the member 111, the front end portions 111a and 112a are returned to a natural state.

  Here, the transmission rod 132 of the support transmission portion 130 is provided with a spring 133 in the vicinity of the connection portion with the connection lever 123, and the movable handle is obtained by rotating the lever handle 122 and pulling the transmission rod 132. When the object 112 is held close to the stationary member 112 and the object is gripped, the spring 133 is elastically stretched according to the operation force, so that the object can be reliably held and held. The pressure contact force of the brush 43 of the polishers 10 and 20, which will be described later, can be adjusted. In addition, the YATCO 100 includes an umbrella cover 134 for dripping moisture from the gripping part 110 side, and an umbrella cover 135 indicating a limit position where the work can be safely performed in consideration of insulation from a work target electric wire or the like. It is provided on the support rod 131 and the transmission rod 132 of the support transmission portion 130.

  Returning to FIGS. 1 and 2, the polishers 10 and 20 include an attachment portion 30 that is attached to and attached to the stationary member 111 of the gripping portion 110 of the YATCO 100 and the distal end portions 111 a and 112 a of the movable member 112. Since the gripping part 110 of the YATCO 100 rotates the stationary member 111 and the movable member 112 relative to each other, the bottom side of the attachment part 30 located inside the front end parts 111a and 112a can be brought into and out of contact with each other. That is, the polishers 10 and 20 are manufactured as attachments that are attached to and attached to the immovable member 111 of the grip portion 110 of the YATCO 100 and the distal end portions 111a and 112a of the movable member 112, and are designed to function as a polisher. ing. Here, since the wording of the immovable member 111 of the gripping portion 110 of the YATCO 100 and the front end portions 111a and 112a of the movable member 112 is too redundant, in the following, it will be abbreviated as the front end portions 111a and 112a of the YATCO 100. There is also.

  As shown in detail in FIG. 3, the attachment portion 30 includes a box-shaped housing portion 32 that covers and inserts the front end portions 111a and 112a of the Yatco 100, and a front-end portion 111a, The detachable portion 33 is detachably fixed to the 112a and maintains the attached state.

  The box-shaped housing portion 32 is formed with an insertion port 35 that opens to insert the tip portions 111a and 112a of the Yatco 100 into an interior state, and the upper surface side of the insertion port 35 (FIG. 3 ( Above (a), slits 36 are formed to accommodate ribs (not shown) formed on both side surfaces of the tip portions 111a, 112a, and an attaching / detaching portion 33 is disposed between the slits 36. ing.

  The attaching / detaching portion 33 has a through hole 37 penetrating in a vertical direction through a cylindrical shape integrally formed on the upper surface of the box-shaped housing portion 32, and the box-shaped housing portion 32 is inserted into the through-hole 37. Engagement pin 38 for projecting tip 38a inside, and both end portions are fixed to the inner surface of this engagement pin 38 and through hole 37, and tip 38a of this engagement pin 38 projects into box-shaped casing 32. And a spring 39 for energizing the spring 39.

  As a result, the attachment portion 30 is pulled up against the elastic force of the spring 39 by the engagement pin 38 of the attachment / detachment portion 33 picking the large-diameter portion 38b on the rear end side, and the like. 111 a and 112 a can be inserted from the insertion port 35 of the box-shaped housing portion 32, and when the large-diameter portion 38 b of the engaging pin 38 is released, the distal end 38 a of the engaging pin 38 is moved to the distal end portion 111 a of the YATCO 100. , 112a is allowed to enter (engage) into a recess (not shown) formed on the outer surface of 112a, so that it can be fixed by being restricted from being detached from the box-shaped housing portion 32.

  In addition, the attaching / detaching portion 33 has a locking pin 38c erected on the side surface of the shaft portion of the engaging pin 38, and a slit 37a for receiving the locking pin 38c in the through hole 37 so as to be movable in the vertical direction. Is formed.

  As a result, the mounting portion 30 is rotated after the engaging pin 38 has been picked up while the large-diameter portion 38b is picked and the locking pin 38c is removed from the slit 37a, whereby the locking pin 38c is removed. 33 (cylindrical shape) can be locked to the upper surface (side of the slit 37a), and can be held in a state in which the tip 38a does not protrude into the box-shaped housing portion 32 even if the operator releases the hand. . In this state, the front end portions 111a and 112a of the Yatco 100 can be easily inserted from the insertion port 35 of the box-shaped housing portion 32, and then the large diameter portion 38b is rotated in the reverse direction to engage the engagement pin 38. By engaging the locking pin 38c into the slit 37a, the distal end 38a of the engaging pin 38 can be engaged with the recesses on the outer surfaces of the distal end portions 111a and 112a of the YATCO 100 and fixed.

  1 and 2 again, the polishers 10 and 20 have the bottom surface portion 42 of the box-shaped housing portion 32 of the mounting portion 30 in the opposite direction to the insertion direction of the insertion port 35. A brush 43 is fixed to the opposing surface 42a of the bottom surface portion 42 that is extended and located inside the tip end portions 111a and 112a of the Yatco 100 so as to contact and separate from each other.

  This brush 43 is made by densely planting wires (wires) 44a and 44b that are refracted into a "<" shape, and the convex side of the "<" shape of the wire 44a of the polisher 10 is forward. Also, the wire 44b of the polisher 20 is planted so that the concave side of the "<" shape is aligned forward, and the refraction direction of each wire 44a, 44b is set to be opposite to each other. ing.

  Accordingly, as shown in FIG. 5, the polishers 10 and 20 hold the object with the gripping portion 110 of the yatco 100 when the polisher 10 and 20 is attached to and attached to the tip portions 111 a and 112 a of the yatco 100 by the mounting portion 30. By operating in this way, the opposing brush 43 can be approached on the bottom surface portion 42 side of the mounting portion 30, and the object to be polished can be press-contacted so as to be gripped between the brushes 43.

  For this reason, in the polishers 10 and 20 attached to the front end portions 111a and 112a of the Yatco 100, for example, as shown in FIG. 6, the core wire d of the electric wire D is rotated while being pressed so as to be gripped between the brushes 43. As shown in FIG. 10 (b), without deforming the core wire d of the electric wire D by applying a force from one direction, as shown in FIG. 10 (a). The tip of the wire 44a, 44b of the brush 43 can be slid in contact with the surface of the core wire d in a straight state and polished. On the other hand, since the polishers 10 and 20 can be slid and polished so as to be gripped between the brushes 43, as shown in FIG. Can be polished.

  At this time, since the brushes 43 of the polishers 10 and 20 are in sliding contact so that the wires 44a and 44b abut against the surface of the core wire d of the electric wire D, the coating material of the electric wire D remaining on the surface of the core wire d is not present. Even if it remains, it can be removed and polished, and even if an oxide film on its surface is formed, it can be effectively polished. Further, the brushes 43 of the polishers 10 and 20 refract the wires 44a and 44b in the opposite “C” shape so that they do not push and bend the opponent when approaching each other. The core wire d of the electric wire D is sandwiched between them and the tips of the wires 44a and 44b are brought into contact with each other so as to effectively polish the surface of the core wire d. be able to.

  Further, the polishers 10 and 20 are arranged in parallel to the end portion of the extension portion 42b of the bottom surface portion 42 of the mounting portion 30 so as to be opposed to each other and orthogonal to the rotational direction of the tip portions 111a and 112a of the YATCO 100. A pair of protrusions 45 are provided, and these protrusions 45 are operated when the YATCO 100 is operated so as to grip an object with the gripping part 110 to bring the opposing brush 43 closer on the bottom face part 42 side of the attachment part 30. It is designed to function as a rotation fulcrum by bringing the heads into contact with each other.

  As a result, the polishers 10 and 20 use the fact that the tip portions 111a and 112a of the Yatco 100 have some slackness, so that the brushes 45 when the brushes 43 on the bottom surface portion 42 side of the mounting portion 30 facing each other approach. When the heads of each other come into contact with each other, the brushes 43 are rotated so as to be parallel to each other, and the entire surface of the brush 43 is pressed so as to grip the object to be polished such as the core d of the electric wire D. And can effectively polish its surface.

  Thus, in this embodiment, the brushes 43 on the bottom surface 42 side of the polishers 10 and 20 are made to approach from both sides only by attaching the polishers 10 and 20 to the tip portions 111a and 112a of the Yatco 100. You can hold and polish the object you want to polish. Therefore, for example, the surface of the core wire d can be effectively polished without being bent by rotating it while pressing the core wire d of the electric wire D between the brushes 43 of the polishers 10 and 20. The connection work of the electric wire D by a connection sleeve etc. can be made easy.

  Next, FIG. 7 and FIG. 8 are views showing a second embodiment of the polisher according to the present invention. Here, since the present embodiment is configured in substantially the same manner as the above-described embodiment, the same components are denoted by the same reference numerals and the characteristic portions will be described.

  7 and 8, the polishers 50 and 60 are attached by attaching the attachment portions 30 to the tip portions 111a and 112a of the Yatco 100 shown in FIG. 4 in the same manner as the polishers 10 and 20 of the above-described embodiment. The brush 43 in which the wires 44a and 44b refracting in the opposite direction to the “<” are densely planted, the wire 44a and 44b is planted in the plate member 72, and The mounting portion 30 is disposed on the bottom surface portion 42 of the box-shaped housing portion 32.

  The plate member 72 is fixed to the bottom surface portion 42 of the mounting portion 30 via a plurality of springs 73, and the spring 73 supports the plate member 72 on the bottom surface portion 42 of the mounting portion 30 with a uniform elastic force. So that they are evenly distributed over the entire surface.

  Accordingly, when the brushes 43 are pressed against the object to be polished by the brushes 50 and 60, the plate member 72 is inclined by the elastic force of the spring 73 with respect to the bottom surface portion 42 of the mounting portion 30 according to the pressure contact force. As in the polishers 10 and 20 of the above-described embodiment, the wires 44a and 44b of the brush 43 are slid on the entire surface of the object such as the core wire d of the electric wire D without providing the protrusion 45 on the bottom surface portion 42. Can be polished.

  As described above, in the present embodiment, the operational effects of the above-described embodiment can be obtained in the same manner, and in addition, the plate member 72 can be obtained by the elastic force of the springs 73 that are uniformly arranged on the entire surface of the bottom surface portion 42 of the mounting portion 30. The brush 43 can be freely tilted. Accordingly, the brush 43 can be inclined according to the shape of the object to be polished, and the wires 44a and 44b can be more effectively slid in contact with the object such as the core d of the electric wire D and polished effectively. it can.

  Although one embodiment of the present invention has been described so far, it is needless to say that the present invention is not limited to the above-described embodiment, and may be implemented in various forms within the scope of the technical idea. For example, in the above-described embodiment, a case where a brush polishing member is provided will be described as an example. However, the present invention is not limited to this. Needless to say, a sandpaper or a gold scrubber may be provided.
