Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspending tool for suspending an electric wire construction tool at a predetermined position when performing electric wire construction using an indirect live-wiring tool.

[0002]

2. Description of the Related Art Conventionally, when constructing an electric wire, in order to prevent a power failure in the surrounding area, a live wire construction method has been adopted in which the construction is carried out in a live state (a state in which electric current is applied to the electric wire). There is. In the work using this live wire construction method, a covering sheet (hereinafter referred to as an insulating sheet) having an insulating property is used to cover a portion in a current-carrying state to prevent accidental short circuit or electric shock to workers. It was

In addition, as a countermeasure against electric shock accidents, so-called indirect live line work is carried out by using an indirect live line tool provided with a gripping hand that can be opened and closed by remote control at the tip of the rod-shaped main body. Many construction methods are also used. In this indirect live-wire construction method, the above-mentioned indirect live-wire tool is used to hold an appliance for electric wire construction, and a worker installs or removes the appliance at a predetermined location without approaching the construction location.

[0004]

By the way, since the indirect live-wiring tool grasps an electric wire construction tool with a gripping hand at the tip of a long rod-shaped main body, when the tool is heavy, the indirect live-wiring tool is used. The tip side of the tool becomes heavy and difficult to balance. In particular, the above-mentioned insulating sheet and the like must be lifted well in the unfolded state and covered at an appropriate position, so it was extremely difficult to perform such work with an indirect live-wire tool.

When it is desired to cover the vertical surface of a construction site with an insulating sheet, the insulating sheet is fixed to the construction site in the past, but conventionally, the insulating sheet was tied with a string or the like. Since it is a fine work that is not suitable for indirect live-wire tools, the original indirect live-wire construction method could not be performed.

[0006] Therefore, an object of the present invention is to provide a suspending tool for an electric wire construction tool such that an insulating sheet or other electric wire construction tool can be easily attached by using an indirect hot-wiring tool.

[0007]

Means for Solving the Problems, Actions, and Effects The present invention, which has been made to achieve the above-mentioned object, uses an indirect live-wiring tool capable of gripping an article by remote control as described in claim 1. It is a hanging tool for electric wire construction equipment that is attached to a bar-shaped object such as a horizontal girder and hangs the electric wire construction equipment at the mounting position, and is erected at an interval on the upper surface of the base. , The first and second hook-shaped arms whose upper ends are curved in opposite J-shapes in mutually opposite directions, and both curved portions are arranged in parallel, and are provided on the lower surface side of the base, The electric wire construction tool is pulled up to a predetermined position, and it is provided with a hanging means capable of hanging it at that position.

According to the hanging tool for electric wire construction of the present invention,
The first and second hook-shaped arms on the upper surface are caught by a suitable girder, etc. above the construction site, and the suspending means on the lower surface pulls up the wire construction device to the construction site, and the device is in that position. Be hung. In attaching the suspending tool to the horizontally suspended rod-like object, first, the suspending tool is lifted from below the rod-like object so that the rod-like object enters between the first and second hook-shaped arms. Then, when both curved portions are lifted up above the rod-shaped object, the suspending tool is twisted 90 degrees about the vertical line, and the rod-shaped object is simultaneously welcomed inside the first and second hook-shaped arms. . So if you hang down the suspending tool a little,
The second hook-shaped arm is caught by the rod-shaped object, and the attachment of the suspending tool is completed.

The hanging device thus attached cannot be removed from the rod unless it is moved by the reverse procedure of the above procedure, that is, by intentionally lifting the hanging device again and twisting it 90 degrees in the opposite direction. Therefore, it cannot be disengaged from the rod-like object by the movement of the suspending tool during normal use (for example, rotation around the rod-like object or sliding of the rod-like object in the axial direction). Further, since the attachment of the suspending tool is completed only by the operation of raising and lowering the suspending tool and the operation of twisting it, the suspending tool can be easily attached even by using an indirect live-wire tool.

The suspending means provided on the lower surface of the suspending tool may be, for example, one in which a hook is attached to the tip of a rope, a chain or the like, and further, a hoist or a pulley for winding the rope or the chain may be combined. May be. If you pull up the wire construction tool by such a hanging means,
Even if you do not lift heavy equipment with an indirect live-wire tool, you can lift and attach only light hanging equipment, and you can easily lift the heavy equipment by the hanging means of the hanging equipment to the construction site. it can.

In particular, when the insulating sheet exemplified in the prior art is attached to a construction site, each suspending means of several suspenders is attached to the upper end portion of the insulating sheet in a safe place without electric shock. It can be easily done by connecting it to several places of the above, attaching the suspending tool to an appropriate position such as a girder above the construction site with an indirect live-wire tool, and then pulling up the insulating sheet to the construction site with the suspension means. You can cover the construction site with the insulation sheet spread out. Therefore, the installation of the insulating sheet is completed even if the worker does not approach the construction site, and the safety of the work in the live wire construction method is improved.

By the way, in the hanging tool of the present invention, the rod-shaped object is first passed between the first and second hook-shaped arms, and then the rod-shaped object penetrates through the opening portions of both hook-shaped arms, and finally. A rod-shaped object enters the concave portion formed by bending. Therefore, as described in claim 2 of the present invention, the interval between the first and second hook-shaped arms is
It is desirable that the width be approximately the same as the width of the recess formed by the curve.

With this configuration, the girder having a size that can enter the recess in the width direction can be surely passed between the first and second hook-shaped arms, and moreover, the girders of the first and second hook-shaped arms. The spacing is not unnecessarily large, so the entire suspension is compact. Therefore, it becomes easier to handle with an indirect hot-line tool.

Further, as described in claim 3, it is preferable that the depth of the recess is approximately half the total height of the inverted J-shaped portion including the recess. In this way, the girder of the dimension that can enter the recess in the height direction is
Since the opening portion of the hook-shaped arm can be surely passed and the opening portion does not become uselessly large, the entire hanging device becomes compact. Therefore, even in the case of such a configuration, the handling by the indirect hot-line tool becomes easier.

By the way, since the hanging tool of the present invention is attached to a rod-like object by using an indirect live-wire tool, it is desirable that the hanging tool can be reliably gripped by the indirect live-wire tool. For that purpose, as described in claim 4, it is preferable that the base portion is made of a plate-shaped body extending in a standing direction of the first and second hook-shaped arms.

[0016] According to the hanging tool configured as described above,
The base part can be easily sandwiched by an indirect live-wire tool from the plate thickness direction, and can be easily lifted upward with both hook-shaped arms facing upward. Further, as described in claim 5, a non-slip member having a large surface frictional resistance and serving as a non-slip when the base is gripped by the indirect hot-line tool may be provided on the outer peripheral surface of the base. good.

According to this structure, a frictional force acts between the gripping hand of the indirect live wire tool and the suspending tool, and the suspending tool is prevented from dropping from the gripping hand. Further, although various configurations can be considered as the suspending means, as described in claim 6, the suspending means includes a pulley hung on the lower surface of the base, a rope passed through the pulley, and It is preferable that the rope is provided at the end portion of the rope and is configured with a hook that can be hooked on a wire construction tool.

According to the hanging device thus constructed, when the hook is hooked on the electric wire construction device and the rope is pulled, the device is pulled toward the pulley, and when the device is pulled up to the desired position, it can be easily accessed. You can tie the rope to the appropriate place in the box and hang the device. With such a suspending means, the structure can be constructed at a relatively low cost and the desired effect can be sufficiently obtained.

[0019]

Embodiments of the present invention will now be described with reference to the drawings. The hanging tool 1 for the electric wire construction tool as an example is
As shown in FIG. 1, a nylon attachment member 3 attached to a girder or the like at the upper part of the electric chamber frame, a nylon pulley 5 hung from a lower portion of the attachment member 3 through a vinylon rope 4, and a pulley. The rope 7 is made of vinylon, and the resin hooks 9 are provided at both ends of the rope 7.

Of these components, the mounting member 3 includes a plate-shaped base portion 11 extending in the vertical direction, as shown in FIG.
The first and second hook-shaped arms 13 and 15 are provided upright on the upper surface of the base portion 11 with a space therebetween, and are arranged on the outer peripheral surface of the base portion 11.
Anti-slip rubber 19 fixed with a BS resin stopper 17
And a through hole 21 for allowing the rope 4 to pass therethrough. As shown in the drawing, the upper ends of the first and second hook-shaped arms 13 and 15 are curved in opposite J-shapes in opposite directions, and both curved portions are arranged in parallel.

Next, a method of using the suspending tool 1 thus constructed will be described. First, the mounting member 3 is gripped by the indirect live-wire tool, and the girder F above the construction site enters between the first and second hook-shaped arms 13 and 15 as shown in FIG. 3A. In such a direction, the girder F is lifted in the direction of the arrow P from below. Then, as shown in FIG. 3B, when the curved portions of both the first and second hook-shaped arms 13 and 15 are lifted above the girder F, the mounting member 3 is moved in the direction of the arrow Q in the figure. It is twisted 90 degrees. As a result, as shown in FIG. 3C, the girder F is simultaneously welcomed inside the first and second hook-shaped arms 13 and 15. Then, when the mounting member 3 is lowered in the direction of the arrow R in the drawing, as shown in FIG.
The second hook-shaped arms 13 and 15 are caught by the girder F, and the attachment of the attachment member 3 is completed. The mounting member 3 thus mounted cannot be removed unless it is moved by an intentional procedure of lifting the mounting member 3 and twisting it by 90 degrees in the direction opposite to the direction of the arrow Q in the drawing. Therefore, the mounting member 3
Even if the girder F is rotated around the girder F or is slid along the girder F, there is no fear that the girder F will come off.

When the mounting member 3 is mounted in this way,
A resin hook 9 at one end of the rope 7 shown in FIG.
Hook the wire construction tool. Then, the other end of the rope 7 is pulled to pull up the wire construction tool toward the pulley 5. After pulling up the electric wire construction tool to an appropriate position, hook the resin hook 9 at the other end of the rope 7 somewhere or tie the rope 7 to an appropriate place. As a result, the wire construction tool is suspended near the construction site.

Since the hanging tool 1 used in this way can hang the apparatus at a desired position, especially when an insulating sheet for covering a current-carrying part is mounted on a vertical surface of a construction site. Suitable for In the case of an insulating sheet, it must be hung in an unfolded state, so use several hanging tools 1 and hook the resin hook 9 of each hanging tool 1 into a hole or the like provided at the upper end of the insulating sheet. Hanging from several places.
The lower end of the insulating sheet hangs downward due to its own weight even if it is not fixed, so the vertical surface of the construction site is covered by this alone. When the insulating sheet is attached to the construction site by such a method, the installation of the insulating sheet is completed even if the worker does not approach the construction site, and the safety of the work in the live-wire construction method is improved.

By the way, the mounting member 3 of this embodiment is shown in FIG.
As shown in FIGS. 1A and 1B, the first and second hook-shaped arms 1 are provided.
The distance A between the grooves 3 and 15 is substantially the same as the width B of the concave portion 25 formed by the curve, and the depth C of the concave portion 25 is about half the total height D of the inverted J-shaped portion including the concave portion 25. The dimensions are. This ensures that a girder having a size (that is, width B and height C) that can enter the recess 25 is passed through, and that the entire mounting member 3 is made as small as possible, and the mounting member 3 is used with an indirect hot-line tool. This is for easy handling.

As described above, the hanging tool 1 of this embodiment
According to the above, the upper ends of the first and second hook-shaped arms 13 and 15 are curved in opposite J-shapes in opposite directions, and
Since both curved portions are arranged parallel to each other, they are erected on the upper surface of the base portion 11 with a space therebetween. Therefore, as described above, the mounting member 3 can be mounted on the girder by an extremely simple operation, and cannot be easily removed. . Therefore, even with the use of the indirect live-line tool, the mounting work can be performed reliably and easily.

Also, if the hanging tool 1 is attached to an appropriate position with an indirect live-wire tool, the electric wire construction tool can be hooked on the resin hook 9 and pulled up by the rope 7, so that a heavy tool or a large insulating sheet can be used. It can be lifted easily even with the help of a worker without having to approach the construction site. Therefore, safety in electric wire construction is improved.

Further, since the base portion 11 is a plate-shaped body, it can be easily gripped by an indirect live-wire tool, and in particular, since the outer peripheral portion thereof is covered with the anti-slip rubber 19, the mounting member 3 can be removed from the gripping hand of the indirect live-wire tool. It also has the effect of preventing slipping, and is extremely easy to handle with an indirect hot-line tool.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modes can be adopted without departing from the scope of the present invention.
