Description

The present invention relates to an auxiliary tool for an insulating operation rod. In particular, it is an auxiliary tool for insulating operation rods that can be detachably connected to the grip of an insulating operation rod such as a shared operation rod that can share advanced tools for different purposes, and can reduce the burden on the operator, and is a safe and stable indirect. Regarding the structure of auxiliary tools for insulating operation rods that can be used for live-line work.

It is known that there are two types of live-line work in which high-voltage distribution lines are distributed without power failure, the direct live-line method and the indirect live-line method. In the direct live-line method, the worker wears protective equipment such as high-voltage rubber gloves and directly touches the high-voltage distribution line that is energized to perform the power distribution work. On the other hand, in the indirect hot-line construction method, the operator can perform the distribution work by using an insulating operation rod (hot stick) or the like without directly touching the high-voltage distribution line being energized.

Generally, the insulating operation rod is composed of a long operation rod and a power distribution work tool (hereinafter referred to as a tip tool) attached to the tip of the operation rod. The insulating operation rod is configured so that the tip tool can be replaced according to the application such as gripping or cutting a high-voltage distribution line.

Various types of insulating operation rods for such indirect hot-line work have been developed, but so-called shared operation rods that can share advanced tools for different purposes are disclosed in the prior art documents (the prior art document). For example, see Patent Document 1).

FIG. 5 is a front view showing the configuration of an insulating operation rod according to an example. FIG. 6 is an enlarged perspective view of the tip end side and the base end portion side of FIG. FIG. 7 is a front view showing a configuration of an example of a tip tool that can be attached to and detached from the tip of an insulating operation rod. Note that FIG. 5 of the present application corresponds to FIG. 6 of Patent Document 1.

Referring to FIG. 5, the insulating operation rod (hereinafter referred to as a shared operation rod) 7 according to an example includes a tool portion 71, a handle portion 72, and a grip portion 73. A tip tool such as a bind hammer 8 described later can be attached to and detached from the tool portion 71 (see FIG. 7). The grip portion 73 is provided with anti-slip so that the worker can easily grip it. The handle portion 72 connects the tool portion 71 and the grip portion 73, and is made of a long tube having an insulating property.

Referring to FIG. 5, the handle portion 72 has a conical draining collar 7a attached to the intermediate portion. The draining collar 7a can block the water advancing from the tool portion 71. Further, a conical limit flange 7b is attached to the connection portion between the handle portion 72 and the grip portion 73. The mounting position of the limit collar 7b indicates the limit at which the shared operation rod 7 can be safely operated in consideration of the insulating property.

Referring to FIG. 5 or FIG. 6, the tool portion 71 includes a columnar shaft portion 71a and a pair of pins 71b and 71b. Further, the tool portion 71 has a push rod 71c and a ring nut 71d. The shaft portion 71a projects in the axial direction of the handle portion 72. The pair of pins 71b and 71b project from the outer periphery of the shaft portion 71a in opposite directions.

Referring to FIG. 6, the push rod 71c is urged by a compression coil spring (not shown) built in the tool portion 71 and protrudes from the tip surface of the shaft portion 71a.

Referring to FIG. 6, the ring nut 71d is arranged below the shaft portion 71a. The ring nut 71d is screwed with the shaft portion 71a. When the ring nut 71d is rotated in one direction, it comes into contact with the bottom surface of the joint portion 81 of the bind hammer 8 described later (see FIG. 7), and the bind hammer 8 can be fixed. When the ring nut 71d is rotated in the other direction, the ring nut 71d is separated from the bottom surface (see FIG. 7) of the joint portion 81 of the bind hammer 8 described later, and the bind hammer 8 can be released.

Referring to FIG. 5 or FIG. 6, the shared operation rod 7 further includes a cylindrical joint portion 74 at the base end portion. The joint portion 74 is formed in a cylindrical shape with an open bottom surface. The joint portion 74 has a shaft hole 74a into which the shaft portion of a foot rod (not shown) is fitted.

Further, referring to FIG. 5 or FIG. 6, the joint portion 74 has a pair of T-shaped engaging grooves 74b and 74b. After inserting a pair of pins provided on the addition rod (not shown) in the axial direction of the shaft hole 74a, these pins are rotated in the circumferential direction of the shaft hole 74a to make these pins into the engaging grooves 74b and 74b. Can be engaged. That is, an addition rod (not shown) can be added to the shared operation rod 7 shown in FIG.

The engaging means as described above is called a twist lock. Then, referring to FIG. 5 or FIG. 6, in a state where the addition rod (not shown) and the joint portion 74 are fitted to each other, the push rod presses the upper wall of the shaft hole 74a and the ring nut is placed on the bottom surface of the shaft hole 74a. A stick (not shown) can be securely fixed to the joint portion 74 by abutting against the joint portion 74.

For example, with reference to FIG. 5 or FIG. 6, a tip tool such as a hook-shaped bind hammer 8 can be attached to the tool portion 71 of the shared operation rod 7 (see FIG. 7).

Referring to FIG. 7, the bind hammer 8 can be detachably attached to the tool portion 71 of the shared operation rod 7 (see FIG. 5 or FIG. 6). The bind hammer 8 is provided with a cylindrical joint portion 81 at the base end portion.

Referring to FIG. 7, the joint portion 81 is formed in a cylindrical shape having an open bottom surface. The joint portion 81 has a shaft hole 81a into which the shaft portion 71a (see FIG. 6) is fitted. Further, the joint portion 81 has a pair of T-shaped engaging grooves 81b and 81b. After inserting a pair of pins 71b / 71b (see FIG. 6) in the axial direction of the shaft hole 81a, these pins 71b / 71b are rotated in the circumferential direction of the shaft hole 81a to obtain these pins 71b / 71b. It can engage with the engagement grooves 81b and 81b.

With reference to FIGS. 5 to 7, when the tool portion 71 and the joint portion 81 are fitted, the push rod 71c represses the upper wall of the shaft hole 81a, and the ring nut 71d hits the bottom surface of the shaft hole 81a. The bind hammer 8 can be securely fixed to the tool portion 71 in contact with the tool portion 71.

Referring to FIG. 7, the bind hammer 8 includes a rod-shaped shaft portion 8s and a hook portion 8a. The hook portion 8a is continuously bent in a C shape from the shaft portion 8s. Further, the bind hammer 8 is provided with a columnar pin portion 8p. The pin portion 8p protrudes from the shaft portion 8s on the side opposite to the opening 8k of the hook portion 8a. The name of the bind hammer is derived from the fact that the bind wire that supports the high-voltage distribution line on the insulator can be operated.

The shared operation rod 7 shown in FIG. 5 or FIG. 6 is a kind of insulating operation rod suitable for indirect hot-line work, but is particularly a “shared operation rod” because tip tools for different purposes can be freely connected. is called.

With reference to FIG. 5 or FIG. 6, a tip tool of a heavy object such as a compression tool may be attached to the tip of the shared operation rod 7. The shared operation rod 7 grips the grip portion 73 with both hands to operate the tip tool, but there is a problem that it is not easy to operate the tip tool when the tip tool is a heavy object. Further, when the tip tool is a heavy object, the physical and mental burden on the worker increases, which is a factor of increasing the fatigue of the worker.

From the above, by detachably attaching the arm support member to which the arm can be inserted into the grip of the shared operation rod, the operator can secure stable support performance to the arm of the operator. Auxiliary tools for insulating operation rods that can expand the working range are disclosed (see, for example, Patent Document 2).
