Description

本発明は主として架線工事に用いる遠隔操作用ヤットコに関するものである。   The present invention relates to a remote control yakko mainly used for overhead wire work.

架線工事において、電線、スリーブ、検電器、補修カバーなどを遠隔操作で把持しうる工具として、遠隔操作用ヤットコが用いられている(特許文献1参照)。   In overhead wire construction, a remote control YATKO is used as a tool that can grip an electric wire, a sleeve, a voltage detector, a repair cover, and the like by remote control (see Patent Document 1).

そして従来の遠隔操作用ヤットコは、図5に示すように、遠隔操作棒1の先端部に固定把持部2と可動把持部3とを備え、可動把持部を遠隔操作により回転させることによって、固定把持部2の先端把持面4と可動把持部3の先端把持面5との間で被把持物を把持するように構成されている。

The object to be grasped is configured to be gripped between the tip gripping surface 4 of the gripper 2 and the tip gripping surface 5 of the movable gripper 3.
JP 2003-170364 A

上記従来の遠隔操作用ヤットコは、固定把持部の先端把持面と可動把持部の先端把持面との間に被把持物を把持する構成となっているため、軟らかい被覆部を有する被覆電線や、把持するために都合の良い平面部を有する検電器、補修カバーなどの把持には適しており、落下事故などを起こさず、確実にこれらの被把持物を把持して架線工事などを行うことができる。   Since the conventional remote control yatco is configured to grip the object to be gripped between the tip gripping surface of the fixed gripping part and the tip gripping surface of the movable gripping part, a covered electric wire having a soft covering part, It is suitable for gripping voltage detectors, repair covers, etc. that have a convenient flat part for gripping, and it is possible to securely grip these objects and perform overhead work without causing a fall accident. it can.

しかし、従来の遠隔操作用ヤットコは、その把持面が平面で、比較的小面積であるため、硬くて円形断面を有する電線の芯線部やスリーブを確実安定に把持することが困難で、架線工事などの作業中に落下事故を起こす危険性が大であるという問題があった。   However, the conventional remote control YATCO has a flat gripping surface and a relatively small area, so it is difficult to reliably and securely grip the core and sleeve of a wire with a hard and circular cross section. There was a problem that the risk of dropping accidents during work was great.

本発明は上記課題を解決するため、遠隔操作棒の先端に固定把持部と可動把持部とを備え、固定把持部の先端把持面と可動把持部の先端把持面との間隔が、遠隔操作により可動把持部を回動させることによって変化する遠隔操作用ヤットコにおいて、固定把持部の中間部に、凹状把持面を有するサブ把持体を、可動把持部側に向けて進出する進出位置と、後退する後退位置との2位置のいずれかに設定できるよう進退動可能に取付け、前記サブ把持体を前記後退位置に設定したとき、被把持物を固定把持部の先端把持面と可動把持部の先端把持面との間に把持でき、前記サブ把持体を前記進出位置に設定したとき、被把持物を可動把持部の中間部とサブ把持体の凹状把持面との間に把持できるように構成したことを特徴とする。   In order to solve the above problems, the present invention is provided with a fixed gripping portion and a movable gripping portion at the tip of a remote control rod, and the distance between the tip gripping surface of the fixed gripping portion and the tip gripping surface of the movable gripping portion is controlled by remote control. In the remote control yatco that changes by rotating the movable gripping part, the sub gripping body having the concave gripping surface is moved backward toward the movable gripping part in the middle part of the fixed gripping part and retreats. When the sub-gripping body is set to the retracted position so that it can be set to one of the two positions of the retracted position and the sub-gripping body is set to the retracted position, the object to be grasped is grasped at the tip gripping surface of the fixed gripper and the tip of the movable gripper. Configured so that the object to be gripped can be gripped between the intermediate portion of the movable gripping portion and the concave gripping surface of the sub gripping body when the sub gripping body is set at the advanced position. It is characterized by.

本発明によれば、サブ把持体を後退位置に設定したときは、従来の遠隔操作用ヤットコと同様に固定把持部の先端把持面と可動把持部の先端把持面との間に、被覆電線、検電器、補修カバーなどを把持でき、サブ把持体が邪魔にならず、固定把持部と可動把持部が含まれる空間の全体を利用して、比較的大型の被把持物を、屈曲等の変形を与えることなく把持することができる。他方、サブ把持体を進出位置に設定したときは、固定把持部の中間部とサブ把持体の凹状把持面との間に、円形断面を有する被覆電線、特に硬くて円形断面を有する電線の芯線部やスリーブを、その移動を拘束した状態で、確実に把持することができる。そして、各種の被把持物のそれぞれの把持に適した状態に切り替える操作は、サブ把持体の進退動位置を切替える動作で行うことができるため、容易である。   According to the present invention, when the sub gripping body is set in the retracted position, the covered electric wire, between the tip gripping surface of the fixed gripping portion and the tip gripping surface of the movable gripping portion, as in the conventional remote control yakko, Capable of gripping voltage detectors, repair covers, etc., the sub gripping body does not get in the way, and the entire space including the fixed gripping part and the movable gripping part is used to deform a relatively large object to be gripped. It is possible to grip without giving. On the other hand, when the sub gripping body is set to the advanced position, the core wire of the covered electric wire having a circular cross section, in particular, a hard and circular cross section, between the intermediate portion of the fixed gripping portion and the concave gripping surface of the sub gripping body. The part and the sleeve can be reliably gripped in a state where the movement is restricted. The operation for switching to a state suitable for each gripping of various objects to be gripped can be easily performed because the operation can be performed by switching the advance / retreat position of the sub gripper.

A screw shaft 29 that is guided by passing through the guide hole 26 is implanted and fixed to the fixed grip portion 2. A positioning nut 30 is screwed into a portion protruding from the right side plate portion 23 of the screw shaft 29. The positioning nut 30 includes a large-diameter portion 31 for rotating operation and a small-diameter portion 32 fitted into the circular recesses 27 and 28. When the positioning nut 30 is loosened and the small-diameter portion 32 is detached from the circular recesses 27 and 28, the positioning nut 30 is tightened in a state where the sub-gripping body 21 is rotated upward and positioned at the advanced position. Thus, by fitting the small-diameter portion 32 into the lower circular recess 28, the sub-gripping body 21 can be fixed at the retracted position.

図4は、サブ把持体21を前記後退位置に固定して使用する場合を示しており、これは図5に示す従来の遠隔操作用ヤットコと同様の使用状態を示している。前記遠隔操作棒1のハンドル8を操作して、補助操作棒7を下動させると、図に仮想線で示すように、可動把持部3は固定把持部2に接近するように回動し、これらの把持面5、4間に被把持物40aを把持することができる。その際サブ把持体21は、可動把持部3と固定把持部2とで囲まれる空間から、大略後退しているので、被把持物40aが大型のもの等であっても、把持動作の邪魔にはならない。そして図に示すように、被把持物40aが把持に適する平坦面を有するものであれば、これを確実に把持することができる。   FIG. 4 shows a case where the sub-gripping body 21 is used while being fixed at the retracted position, and this shows a use state similar to that of the conventional remote control yakko shown in FIG. When the auxiliary control rod 7 is moved downward by operating the handle 8 of the remote control rod 1, the movable gripping portion 3 is rotated so as to approach the fixed gripping portion 2, as indicated by a virtual line in the figure, The object to be grasped 40a can be grasped between these grasping surfaces 5 and 4. At that time, the sub-gripping body 21 is substantially retracted from the space surrounded by the movable gripping portion 3 and the fixed gripping portion 2, so that even if the object to be gripped 40a is a large object, the gripping operation is obstructed. Must not. As shown in the figure, if the object to be grasped 40a has a flat surface suitable for grasping, it can be reliably grasped.

図3は、サブ把持体21を前記進出位置に固定して使用する場合を示している。前記遠隔操作棒1のハンドル8を操作して、補助操作棒7を下動させると、図に仮想線で示すように、可動操作部3は前進位置にあるサブ把持体21に接近するように回動し、可動把持部3の中間部18とサブ把持体21の1対の凹状把持面20、20との間に被把持物40bを把持することができる。被把持物40bとしては、硬くて円形断面を有する電線の芯線部やスリーブが適しており、また図3に仮想線で示すように直径の異なる各種円形断面の被把持物4bの把持に適用することができる。この使用例においては、例えば芯線の場合その長手方向中央部の一側面に可動把持部3の中間部18が当接し、その長手方向の両側部2箇所の他側面にサブ把持体21の1対の凹状把持面20、20が当接した状態で、芯線を狭圧把持するので、スリーブに曲げ力が作用するが、芯線はそれに耐える硬さを有するため、曲げ変形することなく、確実にこれを把持することができる。   FIG. 3 shows a case where the sub-gripping body 21 is used while being fixed at the advanced position. When the auxiliary operation rod 7 is moved downward by operating the handle 8 of the remote operation rod 1, the movable operation unit 3 approaches the sub-gripping body 21 at the forward position as indicated by a virtual line in the figure. The object to be grasped 40b can be grasped between the intermediate portion 18 of the movable grasping portion 3 and the pair of concave grasping surfaces 20 and 20 of the sub grasping body 21 by rotating. As the object to be grasped 40b, a core portion or a sleeve of an electric wire having a hard and circular cross section is suitable, and as shown by an imaginary line in FIG. 3, it is applied to grasping an object to be grasped 4b having various circular cross sections having different diameters. be able to. In this use example, for example, in the case of a core wire, the intermediate portion 18 of the movable gripping portion 3 abuts on one side surface in the longitudinal direction, and a pair of sub gripping bodies 21 are formed on the other side surfaces of the two side portions in the longitudinal direction. Since the core wire is tightly gripped with the concave gripping surfaces 20 and 20 in contact with each other, a bending force acts on the sleeve. However, since the core wire is hard enough to withstand this, the core wire is securely deformed without bending deformation. Can be gripped.

本発明は上記実施例に示す外、種々の態様に構成することができ、例えばサブ把持体を固定把持部に着脱可能に取付けることができる。   The present invention can be configured in various modes other than those shown in the above-described embodiments. For example, the sub-grip body can be detachably attached to the fixed grip portion.

本発明は、硬くて円形断面を有する被把持物を含めた種々の被把持物を遠隔操作により確実に把持できる架線工事用の遠隔操作用ヤットコとして利用するのに適したものである。   INDUSTRIAL APPLICABILITY The present invention is suitable for use as a remote control yakko for overhead wire construction that can securely grip various objects to be gripped, including objects to be gripped having a hard and circular cross section, by remote control.
