Description

本発明は、対象物切断部と対象物把持部とを備える切断工具に関する。対象物は、例えば、高圧引下用架橋ポリエチレン絶縁電線（ＰＤＣ：ＰｌａｎｅｔｒａｎｓｆｏｒｍｅｒＤｒｏｐｗｉｒｅＣｒｏｓｓｌｉｎｋｅｄｐｏｌｙｅｔｈｙｌｅｎｅ、以下、ＰＤ線と記載することがある。）等の線条類である。 The present invention relates to a cutting tool including an object cutting portion and an object gripping portion. The object is, for example, a line such as a cross-linked polyethylene insulated wire for high-voltage pulling (PDC: Plane transformer Drop wire Crosslinked polyethylene, hereinafter may be referred to as PD wire).

架空敷設された線条類を切断するための切断工具が知られている。 Cutting tools for cutting fictitiously laid wires are known.

例えば、特許文献１（特許第４８６２９８２号公報）には、一対の切断刃を有する切断部と、該一対の切断刃を開閉操作する操作部と、線条類を挟み付ける方向にばね付勢された一対の把持片を含む把持部とを有する切断工具が開示されている。特許文献１に記載の切断工具では、一対の切断刃の切断間隔の中央位置と、一対の把持片の把持間隔の中央位置とが略心合わせされた状態で切断操作が実行される。線条類の切断に際しては、まず、開放レバーの操作により、一対の把持片が互いに離間される。次に、一対の把持片間に、切断すべき線条類が配置される。続いて、開放レバーから手を離すことにより、一対の把持片によって、切断すべき線条類が把持される。その後、一対の把持片によって線条類が把持された状態で、操作部が操作され、一対の切断刃によって、線条類が切断される。切断刃によって切断された線条類の一方側が、一対の把持片によって保持され、切断刃によって切断された線条類の他方側が、片手で把持されているため、切断時に、線条類が跳ね返ることがない。 For example, in Patent Document 1 (Patent No. 4862982), a cutting portion having a pair of cutting blades, an operating portion for opening and closing the pair of cutting blades, and a spring urged in a direction of sandwiching the wires. A cutting tool having a grip portion including a pair of grip pieces is disclosed. In the cutting tool described in Patent Document 1, the cutting operation is executed in a state where the center position of the cutting interval of the pair of cutting blades and the center position of the gripping interval of the pair of gripping pieces are substantially aligned. When cutting the wires, first, the pair of gripping pieces are separated from each other by operating the release lever. Next, the lines to be cut are arranged between the pair of gripping pieces. Subsequently, by releasing the hand from the release lever, the lines to be cut are gripped by the pair of gripping pieces. After that, the operation unit is operated in a state where the wires are gripped by the pair of gripping pieces, and the wires are cut by the pair of cutting blades. Since one side of the wires cut by the cutting blade is held by a pair of gripping pieces and the other side of the wires cut by the cutting blade is held by one hand, the wires bounce off during cutting. Never.

特許第４８６２９８２号公報Japanese Patent No. 4862982

図２乃至図３（Ｂ）を参照して切断工具１の概要を説明する。切断工具１は、対象物切断部２と、対象物把持部４と、対象物切断部２と対象物把持部４とを連結する連結部材５と、付勢部材６とを具備する。図２には、対象物切断部２と、対象物把持部４と、連結部材５と、付勢部材６以外の任意付加的な部材も記載されている。なお、「対象物」は、「切断対象物」を意味し、「対象物」には、例えば、ＰＤ線等の線条類が含まれる。 The outline of the cutting tool 1 will be described with reference to FIGS. 2 to 3B. The cutting tool 1 includes an object cutting portion 2, an object grip portion 4, a connecting member 5 that connects the object cutting portion 2 and the object grip portion 4, and an urging member 6. FIG. 2 also shows an object cutting portion 2, an object gripping portion 4, a connecting member 5, and an optional additional member other than the urging member 6. The "object" means an "object to be cut", and the "object" includes, for example, lines such as PD lines.

対象物切断部２は、第１刃体１２と、第２刃体２２とを備える。第１刃体１２が、第１軸まわりに、第２刃体２２に対して相対的に回動することにより、第１刃体１２と第２刃体２２とが閉状態（切断位置）、または、開状態（開放位置）になる。 The object cutting portion 2 includes a first blade body 12 and a second blade body 22. The first blade body 12 rotates relative to the second blade body 22 around the first axis, so that the first blade body 12 and the second blade body 22 are closed (cutting position). Alternatively, it becomes an open state (open position).

対象物把持部４は、第１把持部材３２と第２把持部材４２とを備える。第１把持部材３２が、第１軸まわりに、第２把持部材４２に対して相対的に回動することにより、第１把持部材３２と第２把持部材４２とが閉状態（把持位置）、または、開状態（開放位置）になる。 The object gripping portion 4 includes a first gripping member 32 and a second gripping member 42. The first gripping member 32 rotates relative to the second gripping member 42 around the first axis, so that the first gripping member 32 and the second gripping member 42 are closed (grip position). Alternatively, it becomes an open state (open position).

対象物切断部２と対象物把持部４とは、第１軸に沿って配置される連結部材５によって連結される。対象物把持部４の第１把持部材３２には、長穴３３が設けられている。対象物把持部４が対象物を把持していない時、または、対象物把持部４が小径の対象物を把持している時、連結部材５は、長穴３３の第１位置にある。他方、対象物把持部４が大径の対象物を把持している時、連結部材５は、長穴３３の第２位置にある。当該長穴３３の存在により、対象物把持部４は、対象物の径に依存することなく、対象物を効果的に把持することが可能である。また、当該長穴３３の存在により、対象物が対象物把持部４に把持される際に、対象物が過剰に潰れるおそれがない。これらの効果が生じるメカニズムの詳細については、後述される。 The object cutting portion 2 and the object grip portion 4 are connected by a connecting member 5 arranged along the first axis. An elongated hole 33 is provided in the first gripping member 32 of the object gripping portion 4. When the object gripping portion 4 is not gripping the object, or when the object gripping portion 4 is gripping the object having a small diameter, the connecting member 5 is in the first position of the elongated hole 33. On the other hand, when the object gripping portion 4 grips an object having a large diameter, the connecting member 5 is in the second position of the elongated hole 33. Due to the presence of the elongated hole 33, the object gripping portion 4 can effectively grip the object without depending on the diameter of the object. Further, due to the presence of the elongated hole 33, there is no possibility that the object is excessively crushed when the object is gripped by the object grip portion 4. Details of the mechanism by which these effects occur will be described later.

図６（Ａ）および図６（Ｂ）は、第３ステップＳ３の実行後における切断工具１の状態を示す。図６（Ａ）および図６（Ｂ）に記載の例では、第１ジョー３５の第１把持面３７と、第２ジョー４５の第２把持面４７との間で、太径の線条類Ｗ２が把持されている。図６（Ａ）および図６（Ｂ）に記載の状態では、太径の線条類Ｗ２は、一対の切断刃部（１５、２５）によって、切断されている（図示されず）。第１ジョー３５および第２ジョー４５は、一対の切断刃部（１５、２５）による線条類Ｗ２の切断の前後において、切断箇所の一方側の線条類Ｗ２を把持する。なお、切断箇所の他方側の線条類Ｗ２は、切断工具１とは異なる把持工具によって把持されていてもよい。 6 (A) and 6 (B) show the state of the cutting tool 1 after the execution of the third step S3. In the example shown in FIGS. 6 (A) and 6 (B), a large diameter wire is formed between the first gripping surface 37 of the first jaw 35 and the second gripping surface 47 of the second jaw 45. W2 is gripped. In the state shown in FIGS. 6 (A) and 6 (B), the large-diameter wires W2 are cut (not shown) by a pair of cutting blades (15, 25). The first jaw 35 and the second jaw 45 grip the wires W2 on one side of the cutting portion before and after cutting the wires W2 by the pair of cutting blades (15, 25). The wires W2 on the other side of the cutting portion may be gripped by a gripping tool different from the cutting tool 1.

図６（Ａ）および図６（Ｂ）に記載の状態において、第１把持部材３２の背面３９は、付勢部材６によって、押圧付勢されている。しかし、第１把持面３７と第２把持面４７との間に太径の線条類Ｗ２が介在しているため、第１ジョー３５と第２ジョー４５とは、付勢部材６による付勢力に抗して、離間されている。その結果、第１軸部材５１は、第２位置に位置している。第１把持部材３２と第２把持部材４２とが、把持位置である閉位置にあり（換言すれば、第１刃体１２と第２刃体２２とが、切断位置である閉位置にあり）、かつ、第１軸部材５１が第２位置にある時、第１把持部材３２の第１把持面３７と第２把持部材４２の第２把持面４７との間には、第２隙間が形成される。第２隙間は、相対的に大きな隙間（第１隙間よりも大きな隙間）であり、大径の線条類Ｗ２が効果的に把持されるのに適している。そして、線条類が、細径の線条類Ｗ１より太く、太径の線条類Ｗ２より細い場合は、第１軸部材５１は第１位置と第２位置の間に位置する。つまり、線条類の径に応じて、第１軸部材５１は、第１位置と第２位置との間で移動することができることから、異なる径の線条類を、効果的に把持することができる。 In the state shown in FIGS. 6A and 6B, the back surface 39 of the first gripping member 32 is pressed and urged by the urging member 6. However, since the large-diameter wires W2 are interposed between the first gripping surface 37 and the second gripping surface 47, the first jaw 35 and the second jaw 45 are urged by the urging member 6. Is separated against. As a result, the first shaft member 51 is located at the second position. The first gripping member 32 and the second gripping member 42 are in the closed position which is the gripping position (in other words, the first blade body 12 and the second blade body 22 are in the closed position which is the cutting position). Moreover, when the first shaft member 51 is in the second position, a second gap is formed between the first gripping surface 37 of the first gripping member 32 and the second gripping surface 47 of the second gripping member 42. Will be done. The second gap is a relatively large gap (a gap larger than the first gap), and is suitable for effectively gripping the large-diameter wires W2. When the wires are thicker than the small-diameter wires W1 and thinner than the large-diameter wires W2, the first shaft member 51 is located between the first position and the second position. That is, since the first shaft member 51 can move between the first position and the second position according to the diameter of the wires, it is possible to effectively grip the wires having different diameters. Can be done.

実施形態の切断工具１では、第１把持部材３２が、長穴である第３穴３３を備える。このため、対象物把持部４が小径の対象物を把持する時には、小さな第１隙間が形成される。その結果、小径の対象物が効果的に把持される。また、対象物把持部４が大径の対象物を把持する時には、大きな第２隙間が形成される。このため、把持に際して、大径の対象物が過剰に潰れることが抑制される。その結果、大径の対象物の損傷が回避される。 In the cutting tool 1 of the embodiment, the first gripping member 32 includes a third hole 33 which is an elongated hole. Therefore, when the object gripping portion 4 grips an object having a small diameter, a small first gap is formed. As a result, an object having a small diameter is effectively gripped. Further, when the object gripping portion 4 grips an object having a large diameter, a large second gap is formed. Therefore, it is possible to prevent an object having a large diameter from being excessively crushed during gripping. As a result, damage to large diameter objects is avoided.

本発明の切断工具を用いると、より簡易な操作で、対象物を把持しつつ、対象物を切断することが可能である。したがって、対象物の設置業者、対象物の補修業者、あるいは、対象物の撤去業者にとって有用である。 By using the cutting tool of the present invention, it is possible to cut an object while grasping the object with a simpler operation. Therefore, it is useful for an object installer, an object repairer, or an object remover.
