Description

  The present invention relates to a tip tool for a remote gripping tool, and more particularly to a tool that can reliably grip an object even with an existing remote gripping tool.

  Conventionally, Yatsuko (remote gripping tool) that can grip a target object at a remote position is known, and using this Yatco, for example, a protective pipe is put on an electric wire installed on a power pole, Work such as removing the nest of crows nested at the top has been carried out.

  For example, as shown in FIG. 5, such a Yatsuko can be briefly described as follows: a gripping unit 110 that grips an object, an operation unit 120 that is operated by an operator, and the operation unit 120 that is at hand. And a support transmission unit 130 that is disposed on the side and is connected to a distal end position at which the gripping unit 110 is separated to transmit an operation force from the operation unit 120 to the gripping unit 110 to operate. The grip portion 110 of the YATCO 100 is a curved rotation member (rotation main body) that is rotatably supported (connected) about a rotation shaft 113 disposed on the support rod 131 of the support transmission portion 130. Member) 111, and a curved rotation member (rotating main body member) 112 that is fixed (connected) to the support rod 131 of the support transmission unit 130 and rotates relative to the rotation member 111 while remaining stationary. When the rotating members 111 and 112 are rotated relative to each other, the respective leading end portions 111a and 112a are brought into contact with and separated from each other, and the object can be grasped or separated.

  Since this Yatco 100 is based on the basic operation of being sandwiched between the tip portions 111a and 112a of the rotating members 111 and 112 of the grip portion 110, various tip tools have been proposed to provide other functions. For example, it is possible to perform a work like a so-called radio pliers in which a rod-like member having a tapered rod-like member is detachably attached to the tip portions 111a and 112a to bring the rod-like members into contact with each other (for example, so-called radio pliers). , See Patent Document 1).

  However, in such a remote gripping tool, the rotating members 111 and 112 of the gripping part 110 rotate relative to each other about the rotating shaft 113 so that the end parts 111a and 112a come in contact with and separate from each other. Since the rotating members 111 and 112 are formed in a curved shape that is separated from the distal end portions 111a and 112a toward the rotating shaft 113 side, the rotating members 111 and 112 are formed on the rotating shaft 113 side of the distal end portions 111a and 112a. , The rotation members 111 and 112 are separated from each other to form a space.

  For this reason, the remote grasping tool grasps the object to be grasped by sandwiching it between the opposing surfaces of the small-sized tip portions 111a and 112a, or the tip of the rod-shaped member as described in Patent Document 1 above. If the surface of the target object is made of a material that slides, it must be carefully attached so that it cannot be gripped firmly and will not fall off.

  Accordingly, an object of the present invention is to provide a remote gripping tool tip that can be securely gripped even by a remote gripping tool such as a Yatco.

  One aspect of the invention of the tip for a remote gripping tool that solves the above-described problem is a remote gripping tool that grips an object so that the tips of a pair of rotating body members disposed at a remote position come in contact with and separate from each other. A pair of attachment portions attached to the distal end of the rotating body member, and a pair of extensions attached to the attachment portion and gripped so as to sandwich an object by contacting and separating with the turning operation of the turning body member And the one extension portion is formed with a bifurcated portion that is bent inward at the tip end side, and the other extension portion is bent inward at the tip end side between the bifurcated shape portions. A single-shaped portion to be inserted and removed is formed.

  In the aspect of the present invention, by attaching the attachment portion to each of the tip end portions of the rotating body member, the tip portion of the turning body member is bent at the tip end side and the tip end side is bent inward. A pair of extension portions having a single shape portion can be set. Therefore, in the extending direction of the distal end portion of the rotating main body member, the bifurcated portion of the pair of extending portions bent inward and the distal end side of the single-shaped portion intersect or are closer to the intermediate portion. The object to be grasped can be grasped.

  As described above, according to one aspect of the present invention, the object can be gripped by a pair of extension portions each having a bifurcated shape portion and a single shape portion that are bent inward and intersect or approach each other. It is possible to maintain a state where the target object is easily and reliably gripped without the target object to be gripped slipping away.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1-6 is a figure which shows 1st Embodiment of the tip tool for remote gripping tools which concerns on this invention.

  In FIG. 1, tip tools 10A and 10B are attached to the gripping part 110 of the Yatco (remote gripping tool) 100 shown in FIG.

  First, as shown in FIG. 5, 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. The YATCO 100 is made of an insulating material such as a plastic or rubber material so that the insulation is ensured, except for a metal grip portion 110 that requires strength and the like.

  The grip portion 110 is formed in an arc shape, is connected to one end side of the transmission rod 132 of the support transmission portion 130, and is pivotally supported around a rotation shaft 113 disposed on the support rod 131 side. A rotating member (rotating main body member) 111, and a rotating member (rotating main body member) 112 which is similarly formed in an arc shape and fixed to one end side of the support rod 131 of the support transmission unit 130, It is comprised by. The gripping part 110 can be gripped so that the target object is sandwiched by the rotating members 111 and 112 rotating relative to each other about the rotating shaft 113 to bring the distal ends 111a and 112a into contact with and away from each other. Is built as such.

  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 connection lever 123 connected to the transmission rod 132 of the support transmission portion 130 and the rotation shaft 121a of the fixture 121 are transmitted to the connection lever 123 and the rotation of the lever handle 122 is transmitted to the support transmission portion 130. A spring material (not shown) that urges the transmission rod 132 to push upward in FIG. 5 (the direction in which the distal end portions 111a and 112a of the rotating members 111 and 112 are separated from each other). It has been made.

  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. 5 and the movable rotating member 111 of the gripping portion 110 is rotated in a direction approaching the stationary rotating member 112, the distal end portions 111 a and 112 a. The objects can be brought close to each other, and the object can be grasped and grasped. On the other hand, when the lever handle 122 is released and the Yatchco 100 is released from the operating force via the transmission rod 132, the transmission rod 132 is pushed upward in FIG. When the member 111 is rotated in a direction away from the stationary rotation member 112, the tip 111a and 112a are separated from each other to return 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 lever handle 122 is rotated to pull the transmission rod 132 to rotate. When gripping the target object with the tip portions 111a and 112a of 111 and 112 approaching, the spring 133 is elastically stretched according to the operation force to maintain the state of gripping and gripping the target object with high reliability. be able to. 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 FIG. 1, the distal end tools 10 </ b> A and 10 </ b> B are provided with a pair of attachment portions 11 and extension portions 31 and 41, thereby allowing the distal end portions 111 a and 112 a of the rotating members 111 and 112 of the gripping portion 110 of the YATCO 100. (Hereinafter, simply shortened with the tip end portions 111a, 112a, etc. of the YATCO 100 as appropriate.) The tools are used in pairs, and each mounting portion 11 is fixed to each of the end portions 111A, 112A of the YATCO 100. It is common to maintain the mounting state while the extension portions 31 and 41 connected to the mounting portion 11 are interlocked with the rotating members 111 and 112 of the YATCO 100, respectively. It is designed to grab and grasp the target object in a cooperative manner.

  The attachment portions 11 of the tip tools 10A and 10B include a box-type housing 12 that is inserted into a state of covering the front-end portions 111a and 112a of the rotating members 111 and 112 of the Yatco 100, and the box-shaped housing 12 that has the front-end portions 111a, The detachable portion 13 is detachably fixed to the 112a and maintains the attached state.

  As shown in FIG. 3, the box-shaped housing 12 is formed with an insertion port 15 that opens to insert the front end portions 111 a and 112 a of the Yatco 100 into an interior state. On the upper surface side (above FIG. 3 (a)), slits 16 for accommodating ribs (not shown) formed on both side surfaces of the tip portions 111a and 112a are formed. A portion 13 is provided. Here, in the drawing, the insertion port 15 is formed in a shape in which the facing distance is further away from the back side because the front end portions 111a and 112a of the YATCO 100 are completely brought into contact with each other when the attachment portion 11 is attached. It is because it cannot be made into a state.

  The attaching / detaching portion 13 has a through-hole 17a penetrating in a vertical direction in a cylindrical portion 17 integrally formed on the upper surface of the box-type housing 12, and the through-hole 17a has a through-hole 17a. An engagement pin 18 for projecting the tip 18a inside, and both ends of the engagement pin 18 and the inner surface of the through hole 17a of the cylindrical portion 17 are fixed, and the tip 18a of the engagement pin 18 is connected to the box-shaped housing. A spring (biasing means) 19 that urges so as to protrude into 12 is housed.

Thereby, the attachment part 11 of tip tool 10A, 10B is
The large-diameter portion 18b on the rear end side of the engaging pin 18 of the detachable portion 13 is picked up and pulled up against the elastic force of the spring 19 so that the tip portions 111a and 112a of the Yatco 100 are inserted into the box-shaped housing 12. As shown in FIG. 4, when the large-diameter portion 18b of the engagement pin 18 is released, the engagement pin 18 is inserted into a recess P formed on the outer surface of the tip end portions 111a and 112a. The tip 18a can be inserted (engaged) to be detached from the box-shaped housing 12, and the tip 18a can be attached and fixed so as not to be detached.
The tip portions 111a and 112a of the Yatco 100 are removed from the mounting portion 11 by picking and pulling up the large-diameter portion 18b of the engagement pin 18 located on the upper surface side of the box-shaped housing 12 of the tip tools 10A and 10B. Can do. Further, the attaching / detaching portion 13 of the tip end tool 10A, 10B inserts the tip end portions 111a, 112a of the Yatco 100 into the box-shaped housing 12 while resisting the elastic force of the spring 19 without pulling up the engaging pin 18. Needless to say, it may be inserted through the mouth 15.

  In addition, the detachable portion 13 has a locking pin 18c standing on the side surface of the shaft portion of the engaging pin 18, while the locking pin 18c can be moved vertically in the through hole 17a of the cylindrical portion 17. A slit 17b for accommodating is formed.

  As a result, the attachment portion 11 of the distal end tool 10A, 10B picks up the large-diameter portion 18b of the engagement pin 18 and lifts it so that the engagement pin 18c is released from the slit 17b, thereby rotating the engagement pin 18c. It can be locked to the upper surface of the columnar portion 17 (side of the slit 17b), and can be held in a state where the tip 18a does not protrude into the box-shaped housing 12 even if the operator releases his / her hand. In this state, the front end portions 111a and 112a of the Yatco 100 can be easily inserted from the insertion port 15 of the box-shaped housing 12 of the mounting portion 11, and thereafter, the large-diameter portion 18b is rotated in the reverse direction to engage. By engaging the locking pin 18c of the coupling pin 18 into the slit 17b, the distal end 18a of the engaging pin 18 is engaged with the depression on the outer surface of the distal end portion 111a, 112a of the YATCO 100, and the distal end tools 10A, 10B are set. can do.

  Returning to FIG. 1, the extension portions 31 and 41 of the distal end tools 10 </ b> A and 10 </ b> B separate the box-shaped housing 12 of the attachment portion 11 from the rotation shaft 113 of the Yatco 100 as illustrated in FIG. 2. The extension portion 31 of the tip tool 10A includes bifurcated portions 32 and 33 extending from both side walls of the box-shaped housing 12 of the attachment portion 11, while the extension portion 41 of the tip tool 10B is The center of the box-shaped housing 12 of the mounting portion 11 is formed so as to include a single-shaped portion 42 extending with a thickness of about the gap between the bifurcated portions 32 and 33.

  The bifurcated portions 32 and 33 and the single-shaped portion 42 of the extended portions 31 and 41 are formed to have a thickness obtained by dividing the width direction of the box-shaped housing 12 of the mounting portion 11 into three equal parts. The holding surface side of the body 12 (the back side with respect to the tip portions 111a and 112a) has grip surfaces 32a, 33a, and 42a that extend in the direction away from the rotation shaft 113 of the YAT 100, and the tip portions 32b, 33b, 42b is formed in a shape that bends inward and intersects. In other words, the bifurcated portions 32 and 33 and the single-shaped portion 42 of the extending portions 31 and 41 have the gripping surfaces 32a, 33a, and 42a on the attachment portion 11 side as they extend the gripping surface side of the box-shaped housing 12. Accordingly, the extension surfaces in the adjacent direction coincide with each other, and the tip portions 32b, 33b, and 42b rotate to a position exceeding the extension surface, and one is provided between the tip portions 32b and 33b of the bifurcated portions 32 and 33. The distal end portion 42 b of the shape portion 42 is inserted / removed with the rotation operation of the rotation members 111, 112 of the YATCO 100. Here, the bifurcated portions 32 and 33 of the extended portions 31 and 41 and the gripping surfaces 32a, 33a and 42a of the single-shaped portion 42 have the same extension surface in the adjacent direction. However, the present invention is not limited to this. For example, it is needless to say that the outer surface may be formed in a shape exceeding the mating extension surface, for example, in a columnar cross section.

  As a result, the extension portions 31 and 41 of the distal end tools 10A and 10B extend in a direction away from the rotation shaft 113 of the distal end portions 111a and 112a of the Yattco 100, thereby causing the rotating members 111 and 112 to rotate. Accordingly, the object can be gripped so that the object is sandwiched between the bifurcated portions 32 and 33 and the single-shaped portion 42, and the gripping surfaces 32a and 33a of the bifurcated-shaped portions 32 and 33 and the single-shaped portion 42 can be gripped. , 42a is in a state where the extension surfaces in the adjacent direction coincide with each other without a gap, so that even an object that is thin like an electric wire or thin like a sheet is gripped so as not to be detached with a desired gripping force. be able to. In addition, the extension portions 31 and 41 are connected to the bifurcated portions 32 and 33 and the one-shaped portion 42 even if the object to be sandwiched slides toward the tip side as the tip portions 111a and 112a of the Yatco 100 approach. The tip portions 32b, 33b, and 42b that are bent inwardly of each other can be kept in a state of being securely gripped by restricting them from coming close to and intersecting and slipping away.

  As described above, in the present embodiment, only the tip tools 10A and 10B are attached to the tip portions 111a and 112a of the YATCO 100 by the attachment portion 11 and set, and the bifurcated portions 32 and 33 of the extension portions 31 and 41 are provided. The object can be gripped by sandwiching it between the shape parts 42, and even if the object tries to slide toward the tip side, the tip part 32b, 33b, 42b is restricted from being detached and gripped securely. The state can be maintained.

  Next, FIG. 6 is a figure which shows 2nd Embodiment of the tip tool for remote gripping tools which concerns on this invention. Here, since the present embodiment is configured in substantially the same manner as the above-described embodiment, the same reference numerals are given to the same configuration, and the characteristic portions will be described (the same applies to other embodiments described below). .

  In FIG. 6, tip tools 10 </ b> A and 10 </ b> B are provided with extension portions 51 and 61 connected to each of the pair of attachment portions 11 instead of the extension portions 31 and 41 in the above-described embodiment. The bifurcated portions 52 and 53 that extend on both side walls of the box-shaped housing 12 of the mounting portion 11 are provided, while the extension portion 61 has the bifurcated portion 52 at the center of the box-shaped housing 12 of the mounting portion 11. It is formed so as to have a single-shaped portion 62 extended with a thickness of about a gap between 53.

  The bifurcated portions 52 and 53 and the single shape portion 62 of the extension portions 51 and 61 are formed to have a thickness obtained by dividing the width direction of the box-shaped housing 12 of the mounting portion 11 into three equal parts. A gripping surface (curved inner surface) that curves in an approaching direction after being separated from each other around an extended surface in a direction away from the rotation shaft 113 of the yatco 100 on the gripping surface side of the body 12 (on the back side with respect to the tip portions 111a and 112a). ) 52a, 53a, and 62a, and the tip portions 52b, 53b, and 62b are formed in an intersecting shape by bending (bending) inward. In other words, the bifurcated portions 52 and 53 of the extension portions 51 and 61 and the single-shaped portion 62 are curved on the gripping surfaces 52a, 53a and 62a on the attachment portion 11 side even when the tip portions 111a and 112a of the YATCO 100 are approached. While the inner surfaces are opposed to each other, the front end portion 62b of the one-shaped portion 62 is between the front end portions 52b and 53b of the bifurcated portions 52 and 53, and the rotation members 111 and 112 of the Yatco 100 are rotated. Inserts / removes with movement.

  As a result, the extension portions 51 and 61 of the distal end tools 10A and 10B extend in a curved shape in the direction separating the distal end portions 111a and 112a of the Yattco 100 from the rotation shaft 113, so that the rotation members 111 and 112 Grasping in a stable state so as to be positioned in the middle part (deepest part) of the curved inner surface so that the target object is sandwiched between the forked parts 52 and 53 and the single-shaped part 62 by being moved away from each other with the turning operation Even if the target object to be sandwiched slides toward the tip side as the tip portions 111a and 112a of the Yatco 100 approach, the tip that curves to the inside of the bifurcated portions 52 and 53 and the single shape portion 62 The state where the parts 52b, 53b, 62b are brought into close / intersect states and slipped and separated further can be restricted and the state of being securely held can be maintained.

  As described above, in the present embodiment, in addition to the function and effect of the above-described embodiment, the target object is positioned so as to be positioned in the middle portion between the bifurcated portions 52 and 53 and the single-shaped portion 62 of the extending portions 51 and 61. The object can be sandwiched and gripped, and the object can be held in a stable state while securing a state in which the object is prevented from slipping toward the distal end side and is separated from the distal end portions 52b, 53b, 52b. It can be securely gripped.

  Here, as another aspect of the present embodiment, as shown in FIG. 7, the extension parts 51, 61 of the distal end tools 10 </ b> A, 10 </ b> B include the bifurcated parts 52, 53 and the attachment part 11 of the one-shaped part 62. Similarly to the tip portions 52b, 53b, and 62b, the opposite end portions of the tip portions 52b, 53b, and 62b that are on the side may also form intersecting portions 52c, 53c, and 62c that curve and protrude toward the inside. . In this case, the intersecting portions 52c and 53c of the bifurcated shape portions 52 and 53 are in a state in which the root of the single shape portion 62 itself is provided between the cross portions 62c and the intersecting portion 62c of the single shape portion 62. Enters between the roots of the bifurcated portions 52, 53 across the intersections 52c, 53c. For this reason, even if the target object to be sandwiched slides toward the rotating shaft 113 as the front end portions 111a and 112a of the YATCO 100 approach, it is curved inward of the bifurcated portions 52 and 53 and the single shape portion 62. It is possible to maintain the gripping state by more reliably limiting the protruding intersecting portions 52c, 53c, and 62c to be in a state of approaching / intersecting and further slipping and detaching to the rotating shaft 113 side.

  The intersecting portions 52c, 53c, and 62c may be formed not only in the present embodiment but also applied to the first embodiment described above, and only in the bifurcated portions 52 and 53 and the single-shaped portion 62. Needless to say, it may be provided only in one of them.

  Next, FIG. 8 and FIG. 9 are views showing a third embodiment of the remote gripping tool tip according to the present invention.

  In FIG. 8, in the tip tool 70, instead of the extension portions 31, 41, 51, 61 in the above-described embodiment, the base end portions of the extension portions 81, 91 have the rotation shaft 71 in each of the pair of attachment portions 11. As shown in FIG. 9, the extension portions 81 and 91 are bifurcated portions in which the extension portions 81 extend from both side walls of the box-shaped housing 12 of the attachment portion 11. On the other hand, the extension portion 91 includes a single-shaped portion 92 that extends from the center of the box-shaped housing 12 of the mounting portion 11 with a thickness about the gap between the bifurcated portions 82 and 83. In the same manner as so-called radio pliers or the like, they are connected to each other by a rotation shaft 72 disposed at an intermediate portion close to the tip end side so as to be relatively rotatable.

  The bifurcated portions 82 and 83 and the single-shaped portion 92 of the extension portions 81 and 91 linearly extend from the rotation shaft 71 to the rotation shaft 72 as the tip tool 70, and then the rotation shaft 72. Further, gripping surfaces (curved inner surfaces) 82a, 83a, and 92a are formed by bending the tip side inwardly, and the tip portions 82b, 83b, and 92b intersect with each other when the tip portions 111a and 112a of the YATCO 100 approach each other. Is formed. That is, even if the bifurcated portions 82 and 83 and the one-shaped portion 92 of the extension portions 81 and 91 are brought close to each other, the gripping surface on the rotating shaft 72 side (attachment portion 11 side) even if the tip portions 111a and 112a of the YATCO 100 are approached 82 a, 83 a, and 92 a have the curved inner surfaces spaced apart from each other, and the tip portion 92 b of the single-shaped portion 92 is between the tip portions 82 b and 83 b of the bifurcated portions 82 and 83, and the rotating member 111 of the Yattco 100. , 112 is inserted / removed with the rotation operation. Here, in the present embodiment, the case where the entire extension portions 81 and 91 are formed in the bifurcated portions 82 and 83 and the single shape portion 92 will be described as an example. However, the present invention is not limited to this. It goes without saying that only the distal end side of the moving shaft 72 may be formed into a bifurcated shape portion and a single shape portion.

  As a result, the extension portions 81 and 91 of the tip tool 70 are located between the bifurcated portions 82 and 83 and the distal end side of the rotating shaft 72 of the single-shaped portion 92 as the rotating members 111 and 112 rotate. Can be gripped in a stable state so as to be positioned at the middle part (deepest part) of the curved inner surface so as to sandwich the target object, and the target object to be sandwiched as the leading ends 111a and 112a of the YATCO 100 approach each other Even if it slips to the front end side, the bifurcated portions 82 and 83 and the front end portions 82b, 83b, and 92b that are curved inwardly of the one-shaped portion 92 become close to each other and cross each other and slip further and detach. Therefore, it is possible to maintain the gripping state reliably.

  As described above, in the present embodiment, in addition to the operational effects of the above-described embodiment, the extension portions 81 and 91 can be handled as the assembled tip tool 70, and can be easily managed and used without falling apart. can do.

  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.
