Description

  The present invention relates to a coating peeling tool for high-pressure underlining. In particular, the present invention relates to a structure of a peeling tool suitable for peeling a coating of a drawn line that branches from a high-voltage distribution line installed on an upper part of an electric pole to a pole transformer or the like by an indirect hot wire method.

  For example, in the replacement work of a pole transformer or cutout (breaker) installed on a utility pole, an underline that branches off from a high-voltage distribution line is created by an indirect hot wire method using an insulation operation rod (hot stick). Disconnected. In order to crimp the terminal of the cut underline with a compression sleeve, an operation of peeling the underline coating using an insulating operation rod has been performed.

  As such a high voltage underline coating peeling tool, the underline coating can be peeled helically by the operation on the hand side of the insulation operating rod, and the stripping length of the coating can be adjusted arbitrarily. A coating peeling tool is disclosed (for example, see Patent Document 1).

  Further, such a high pressure underline coating peeling tool is a coating peeling tool having a pair of opening and closing members that can be mounted on the gripping portion of the insulating operation rod, and these opening and closing members are close to each other. It has a cutting blade with a semicircular cutting edge that cuts the sheath of the electric wire at the tip, and has divided blocks arranged at the lower part of the cutting blade, and the pair of divided blocks have their facing surfaces facing each other. A coating peeling tool is disclosed that has an accommodation hole into which the end of the electric wire can be inserted when in contact, and the end edge of the electric wire abuts the bottom surface of the accommodation hole, thereby defining the cutting length of the coating ( For example, see Patent Document 2).

  The coating peeling tool according to Patent Document 2 can easily cut only the coating so that the pair of cutting blades sandwich the electric wire, and pulls the insulating operation rod in the extending direction of the electric wire while rotating the pair of divided blocks in the circumferential direction. The coating can be peeled off.

  However, the coating peeling tool according to Patent Document 1 may cause a peeling failure because the rotary blade spirally moves with respect to the electric wire to peel off the coating. In this case, there is a concern that the compression sleeve cannot be inserted into the core wire of the electric wire up to a predetermined depth, resulting in poor crimping. There is a need for a coating stripping tool for an indirect hot wire method that can reliably strip the coating on the end of an electric wire with a predetermined stripping length.

  On the other hand, the coating peeling tool according to Patent Document 2 can surely peel the coating of the end of the electric wire with a prescribed peeling length, but there is a problem that when the pair of opening and closing members are opened, the peeled coating is scattered. There is a need for a coating stripping tool for the indirect hot wire method that can reliably recover the stripped coating. The above can be said to be the subject of the present invention.

  The present invention has been made in view of such problems, and can indirectly remove the coating of the terminal of the high-voltage underline with a predetermined peeling length, and can indirectly collect the coating of the peeled high-pressure underline. An object of the present invention is to provide a coating peeling tool for a hot wire method.

Further, a guide plate 12 that guides the second cutting blade 5b until it comes into contact with the first cutting blade 1b is fixed to the distal end portion 11 of the main body 1. Further, on the side surface of the distal end portion 11 of the main body 1, a scale 11 s serving as a guide for the peeling length of the underline W coating is displayed (see FIG. 2).

  Next, referring to FIG. 2 or FIG. 6, when the pair of first cutting blade 1b and second cutting blade 5b are brought into contact with each other, the drawing line is drawn on the right side of the first cutting blade 1b and the second cutting blade 5b. The coating of W can be cut. The drawing line W can be cut on the left side of the first cutting blade 1b and the second cutting blade 5b, and the coating of the drawing line W having a small core diameter can be peeled off on the right side of the first cutting blade 1b and the second cutting blade 5b. Thus, you may comprise the 1st cutting blade 1b and the 2nd cutting blade 5b.

  In order to peel the coating of the drawing line W using the peeling tool 10 configured as described above, first, the drawing line W is set to the main body 1 so as to be substantially orthogonal to the cutting edges of the pair of first cutting blades 1b. It is mounted on the front end portion 11. Next, when the second handle 2h of the operating lever 2 is closed toward the first handle 1h of the main body 1 as shown in FIG. 8 from the state shown in FIG. 2, the second cutting blade 5b and the presser The piece 41 can be moved (rotated) toward the distal end portion 11 of the main body 1.

  In the state shown in FIG. 8, the pressing piece 41 presses the down line W against the tip 11 of the main body 1, and the coating of the down line W is applied between the pair of first cutting blade 1 b and second cutting blade 5 b.

During this time, the pressing piece 41 maintains a state in which the underline W is pressed against the distal end portion 11 of the main body 1. Thereby, the peeling tool 10 can peel the film of the underline W from the core wire.

  Next, the operation of the link mechanism constituting the peeling tool 10 will be described. First, in the state shown in FIG. 2, the first rotation shaft 1s is rotatably inserted into the first connection hole 41h of the second link 4 (see FIG. 3). Further, the connecting pin 3p is located at a position S1 on the tip end side of the first long hole 41e of the second link 4 (see FIG. 3). On the other hand, in the state shown in FIG. 2, the 1 rotation shaft 1 s is located at the position S <b> 1 on the proximal end side of the second long hole 51 e of the third link 5 (see FIG. 4). Further, in the state shown in FIG. 2, the one rotation shaft 1s is located at the position S1 on the base end side of the third elongated hole 61e of the fourth link 6 (see FIG. 5). On the other hand, the connecting pin 3p is located at a position S3 on the lower end side (left side in FIG. 5) of the guide hole 61c of the fourth link 6 (see FIG. 5).

  Next, when the second handle portion 2h is closed toward the first handle portion 1h from the state shown in FIG. 2, the connecting pin 3p draws an arc locus from the position S3 of the guide hole 61c, and the guide hole 61c. To the position S4 on the upper end side (right side in FIG. 5) (see FIG. 5). That is, even if the operation lever 2 is closed, the fourth link 6 does not change from the state shown in FIG. 2 to the state shown in FIG.

  On the other hand, when the second handle portion 2h is closed toward the first handle portion 1h from the state shown in FIG. 2, the connecting pin 3p is restricted by the guide hole 61c and moves in an arc as described above. The two links 4 rotate counterclockwise (arrow L direction) with the first connecting hole 41h as a rotation center (see FIG. 3). That is, when the operation lever 2 is closed, the pressing piece 41 can be moved toward the distal end portion 11 of the main body 1 (see FIG. 8).

  In addition, when the second handle 2h is closed toward the first handle 1h from the state shown in FIG. 2, the connecting pin 3p is restricted by the guide hole 61c and moves in an arc as described above. The three links 5 rotate counterclockwise (arrow L direction) with the position S1 of the third elongated hole 61e as the center of rotation (see FIG. 4). That is, the 2nd cutting blade 5b can be moved toward the 1st cutting blade 1b (refer FIG. 8). In this case, the storage container 7 is arranged so that the opening side does not interfere with the bent piece 51 (see FIGS. 7 and 8).

  Referring to FIG. 8, the operation lever 2 is closed, and the pressing piece 41 is in contact with the distal end portion 11 of the main body 1 and the state immediately before the second cutting blade 5b is in contact with the first cutting blade 1b. Then, a load is generated in the link mechanism that prevents the coating of the underline W from being cut. This load acts to restrict the connecting pin 3p from further rising from the position S4 of the guide hole 61c (see FIG. 5). Therefore, when the second handle 2h is further closed toward the first handle 1h from the state shown in FIG. 8, the connecting pin 3p is guided by the first elongated hole 41e and the first rotating shaft 1s. To the position S2 on the base end side of the first elongated hole 41e (see FIGS. 3 and 9).

  With reference to FIG. 2, when the second cutting blade 5 b moves toward the first cutting blade 1 b, the second cutting blade 5 b descends while sliding on the inclined surface of the guide plate 12. In this case, referring to FIG. 5, the connecting pin 3p moves obliquely backward with respect to the first rotation shaft 1s. That is, the connecting pin 3p slightly moves from the position S4 to the position S5 that contacts the rear edge of the guide hole 61c.

  Referring to FIG. 3, when the connecting pin 3p moves from the position S4 to the position S5, the connecting pin 3p is fitted in the second connecting hole 51h (see FIG. 4), so that the second cutting blade 5b is pulled. A combined operation in which a lowering operation for cutting the coating of the underline W and a moving operation of drawing the coating of the underlining W from the core wire can be performed.

  Referring to FIG. 3, when the connecting pin 3p is moved from the position S1 to the position S2, the connecting pin 3p is fitted in the second connecting hole 51h, so that the first rotating shaft 1s is connected to the third link 5. On the other hand, it moves relatively from position S1 to position 2 (see FIG. 4). That is, the second cutting blade 5b can be translated in a direction away from the first cutting blade 1b (see FIG. 9). In this case, the storage container 7 has a part of the left side surface 7 cut away so that the left side surface 7e does not interfere with the bent piece 51 (see FIGS. 7 and 9).

  Referring to FIG. 3, when the connecting pin 3p moves from the position S1 to the position S2, the movement of the connecting pin 3p is restricted at the position S5 of the guide hole 61c. The four links 6 move relatively from the position S1 to the position S2 (see FIG. 5). That is, the covering drawer piece 61 can be translated in a direction away from the first cutting blade 1b (see FIG. 9). In this case, the storage container 7 is arranged so that the edge of the left side surface 7e is separated from the coated drawer piece 61 so that the edge of the left side surface 7e does not interfere with the coated drawer piece 61 (FIGS. 7 and 9). reference).

  When the operation lever 2 (second handle portion 2h) is released from the state shown in FIG. 9, the return force of the operation lever 2 is biased by the tension coil spring 21. 2 can be restored. Then, the cut coating of the underline W can be collected in the storage container 7 (see FIG. 1 or FIG. 2). The distal end side of the third link 5 constitutes the left side surface of the storage container 7, and the distal end side of the main body 1 constitutes the lower surface of the storage container 7 (see FIGS. 1 and 7).

  Thus, when the operation lever 2 is closed, the peeling tool 10 according to the embodiment cuts the coating of the terminal of the underline W with a predetermined peeling length, and pulls out the cut of the cut down line W from the core wire. Can be carried out continuously. Then, the cut coating of the underline W can be collected in the storage container 7 without being scattered outside.

  Next, an embodiment in which the peeling tool 10 is operated using an insulating operation rod will be described. FIG. 10 is a front view of the high-voltage underline coating / peeling tool according to the embodiment, in which the high-pressure underline coating / peeling tool is connected to a pair of gripping pieces that are opened and closed and arranged on the distal end side of the insulating operation rod. FIG. FIG. 11 is a front view showing a configuration of an insulating operation rod capable of operating the high pressure underline coating peeling tool according to the embodiment.
