Description

  The present invention relates to a nut. In particular, the present invention relates to a nut structure that is used for tightening a member in combination with a bolt or the like, and that can easily perform a temporary tightening operation prior to a final tightening operation at a high place.

  It is known that there are two types of hot-line work for carrying out power distribution work without power interruption of the transmission line: direct hot-wire method and indirect hot-wire method. In the direct hot wire construction method, workers wear protective equipment such as high-pressure rubber gloves and directly carry out power distribution work by touching the current transmission line. On the other hand, the indirect hot wire construction method can use an indirect hot wire tool such as a hot stick (insulating operation rod) to carry out power distribution work without directly touching the current transmission line. In recent years, a shift from a direct hot wire method to an indirect hot wire method is progressing from the viewpoint of improving the working environment.

  The hot stick is equipped with a tool for carrying out power distribution work at the tip, and this tool can be remotely operated by a handy operation unit. An operator who performs power distribution work can perform a work such as “support” or “gripping” at a high place by using a hot stick. In addition, the hot stick can detachably hold a tool at the tip, and supports various operations by exchanging the tool.

  FIG. 8 is a perspective view showing an example of a support fitting mounted on a utility pole. Referring to FIG. 8, the utility pole (not shown) has a brace 7 mounted thereon. The arm metal 7 generally supports a high-voltage electric wire via a lever. In addition, the arm metal 7 may support a pole transformer.

  Referring to FIG. 8, a support fitting 8 is attached to the arm bracket 7. For example, a bird damage prevention device (not shown) for preventing the flying of birds and nesting is supported at the end of the support bracket 8. The illustrated support fitting 8 is constituted by a C-shaped channel-shaped angle member 8a and a bolt member 8b bent in an L shape.

  Referring to FIG. 8, one end of the bolt member 8b is engaged with a long hole 81a opened in the angle member 8a. The other end portion of the bolt member 8b is provided with a male screw portion 81b. The other end of the bolt member 8b passes through a hole provided in the contact plate 8c. Then, the support fitting 8 can be clamped to the arm metal 7 by screwing the nut 8n into the male screw portion 81b. As for the support metal fitting 8, the other end part of the bolt member 8b protrudes comparatively long so that it can respond to the arm metal 7 which has many kinds of width W.

  Referring to FIG. 8, even when the nut 8n is fastened to the bolt member 8b, a hot stick is used for safety measures when a live wire is installed near the support fitting 8. ing. For this reason, the nut 8n is fastened to the bolt member 8b by using a hot stick 9 having an indirect ratchet wrench (hereinafter abbreviated as a ratchet) 90 attached to the tip.

  FIG. 9 is a front view of the hot stick 9 described above. Referring to FIG. 9, the hot stick 9 includes an attaching / detaching portion 91, an operation portion 92, and a handle portion 93. A ratchet 90 is detachably attached to the attachment / detachment portion 91 via a chrysanthemum attachment (not shown). Other tools can also be attached to the detachable portion 91 via a twist lock adapter (not shown).

  Referring to FIG. 9, the operation unit 92 is composed of a long tubular body, and can grip the operation unit 92 and operate the ratchet 90. The handle portion 93 is formed of a long tubular body, and connects the attachment / detachment portion 91 and the operation portion 92. The handle portion 93 is made of an insulating synthetic resin and electrically insulates the detachable portion 91 and the operation portion 92 from each other.

  Referring to FIG. 8, the ratchet 90 is incorporated in the main body 9 h by integrating a socket 9 a having a large diameter and a socket 9 b having a small diameter. The ratchet 90 is a so-called two-size ratchet wrench. Moreover, these sockets 9a and 9b are opened so that the bolt member 8b can be inserted, and the inside penetrates coaxially.

  Referring to FIG. 8, the ratchet 90 includes a ratchet mechanism including a ratchet wheel and a detent for stopping. The ratchet mechanism can rotate the nut 8n only in one direction. Further, when the ratchet 90 is rotated in the opposite direction, the ratchet mechanism turns idle, so that the nut 8n can be fastened quickly. The ratchet 90 is provided with a lever 9c for switching the direction in which the sockets 9a and 9b are idle.

  Referring to FIG. 8, the ratchet 90 includes two joint portions k1 and k2. The joint portion k1 can change the orientation of the sockets 9a and 9b on a horizontal plane. The position of the joint part k2 can be changed so as to turn the sockets 9a and 9b on the vertical plane. At the end of the ratchet 90, a horseshoe-shaped chrysanthemum 9d is provided. Then, the chrysanthemum 9d can be fixed to the attaching / detaching portion 91 (see FIG. 9).

  Referring to FIG. 8 or FIG. 9, since the other end of the bolt member 8b protrudes long, it is necessary to operate the hot stick 9 a considerable number of times from the temporary tightening to the final tightening of the nut 8n. . In particular, using a long hot stick 9 to rotate the nut 8n located at a high place has a heavy physical burden on the worker.

  In order to deal with such problems, a tightening tool that greatly improves the efficiency of nut tightening work in electrical installation work such as an indirect hot wire method is disclosed (for example, see Patent Document 1).

  The tightening tool according to Patent Document 1 includes a cylindrical mounting body having elasticity, and a linear body wound spirally around the outer periphery of the mounting body. In the mounting body, a nut is inserted from the axial direction, and a holding hole that holds the nut so as not to rotate is opened at the center. One end of the linear body is fixed to the outer periphery of the mounting body. Then, when the mounting body is mounted on the bolt together with the nut and the other end portion of the linear body is pulled, the nut can be temporarily tightened quickly.

  Also, a screw body that can easily and quickly perform a rotating operation such as temporary fastening has been disclosed (for example, see Patent Document 2). The screw body according to Patent Document 2 includes a nut main body and a belt-like adhesive tape that is wound in an overlapping manner so as to be attached to the outer periphery of the nut main body.

  The screw body according to Patent Document 2 is capable of rotating the screw body when the start end portion of the adhesive tape is easily fixed from the outer periphery of the nut body and the terminal end portion of the adhesive tape is separated from the screw body. It is said.

JP 2007-104791 A JP 2005-24070 A

  Referring to FIG. 8, nut 8n is mounted in socket 9a (or socket 9b) in advance, and hot stick 9 is operated to mount nut 8n on bolt member 8b. In this case, since the nut 8n is located at a high place, the nut 8n may fall off the socket 9a (or the socket 9b).

  The tightening tool according to Patent Document 1 can quickly and temporarily tighten the nut 8n after the nut 8n is attached to the bolt member 8b. However, in the tightening tool according to Patent Document 1, in order to mount the nut 8n on the bolt member 8b, for example, it is necessary to grip the mounting body on which the nut 8n is mounted using a hot stick provided with a gripping tool. . For this reason, there exists a possibility that the nut 8n may fall off.

  Similarly, the screw body according to Patent Document 2 can quickly temporarily tighten the nut body after the nut body is mounted on the bolt member 8b. However, since the screw body according to Patent Document 2 is wound with the adhesive tape overlapped on the outer periphery thereof, it is difficult to previously attach the nut 8n to the socket 9a (or socket 9b).

  If the nut does not fall off from the ratchet provided at the tip of the hot stick, and if the nut can be fastened to the bolt quickly, the work time can be shortened by the indirect hot wire method, and the operator's fatigue can be reduced. The above can be said to be the subject of the present invention.

  This invention is made | formed in view of such a subject, and it aims at providing the nut which can prevent a nut falling from the socket of a ratchet, and can be temporarily tightened to a volt | bolt quickly.

  The inventors of the present invention wound a strip of tape around the outer periphery of the nut body, and pressed the nut body into the ratchet socket to prevent the nut from falling off, and the nut body was screwed onto the tip of the bolt. After joining, we found that these problems can be solved by pulling the other end of the linear body wound around the outer periphery of the nut body so that the nut body can be rotated and temporarily tightened. Based on this, it came to invent the following new nuts.

The cap is formed at the distal end portion, is formed in a cylindrical fitting portion that is press-fitted into the female screw portion, and is formed at the base end portion, and penetrates from one socket to the other socket. A spindle-shaped head held elastically in the hole.

  (3) It is preferable that the said nut main body has a groove part which can wind the said linear body helically, and this groove part forms the bottom face flat along the outer periphery of the said nut main body.

  (4) It is preferable that the linear body has a tensile strength capable of temporarily fastening the nut body.

  (5) The ratchet wrench may be attached to the tip of the hot stick.

  In the nut according to the present invention, a strip of tape is wound around the outer circumference of the nut body to press the nut body into a ratchet socket to prevent the nut from falling off, and the nut body is screwed onto the tip of the bolt. After joining, the nut body rotates and can be temporarily tightened quickly by pulling the other end of the linear body wound around the outer periphery of the nut body.
