Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a box-like object hanging device suitable for suspending a box-like object from a horizontally stretched linear object such as a power distribution line. .

(Prior art) Devices that measure the temperature of power distribution lines without contact are known as box-shaped objects that are moved along horizontally stretched linear objects such as power distribution lines. The device is moved along the power distribution line by rotating wheels provided on the top of the box-like body on the power distribution line.

By the way, with such a device, it is necessary to first place the wheels on the power distribution line and then use the wheels to suspend the device from the power distribution line. must be located in

(Problem that the invention seeks to solve) However, if the device is simply lifted vertically upwards from beneath the distribution line, the wheels are placed on the center of gravity of the device, so the top of the wheel will hit the bottom of the distribution line. , wheels cannot be placed on power lines.

Therefore, when suspending a device from a power distribution line using wheels, for example, lift the device so that the wheels are positioned to the side of the power distribution line, then move the device horizontally in the direction of the power distribution line and place the wheels on the power distribution line. There was a problem that the work was troublesome and the workability was poor because it was necessary to put the machine on the machine.

The present invention was developed in view of the above-mentioned conventional problems, and its purpose is to provide a box-like object hanging device that can easily suspend a box-like object from a wire-like object such as a power distribution line using wheels. It is about providing.

(Means for Solving the Problems) In order to achieve the above object, the box-shaped object hanging device according to the present invention is provided between a position on the center of gravity of the box-shaped object and a position distant from the center of gravity. is provided on the box-shaped object so as to be able to reciprocate and rotate around its own central axis, and by rotating it on a linear object such as a power distribution line, the box-shaped object can be attached to the linear object. The present invention is characterized in that it has wheels for moving along the box-like object, and wheel reciprocating means provided on the box-shaped object for reciprocating the wheels.

(Function) In the device for suspending a box-shaped object according to the present invention, the box-shaped object is lifted vertically upwards directly below the linear object while the wheels are moved to a position apart from the center of gravity of the box-shaped object. When the height of the lower part of the wheel slightly exceeds the height of the upper part of the linear object, the wheel is moved to the center of gravity of the box-shaped object.

(Embodiment) Hereinafter, a preferred embodiment of the box-shaped object hanging device according to the present invention will be described based on the drawings.

In FIG. 1, a box-shaped object 1 to which the box-shaped object hanging device according to the present invention is applied is a known device configured to be able to measure the temperature of a power distribution line 3 (wire-shaped object) without contact, for example. A wheel 5 is provided on the top thereof.

The wheels 5 are placed on the power distribution line 3 and rotated to move the box-like object 1 along the power distribution line 3 while the box-like object 1 is suspended from the power distribution line 3 .

And, as understood from FIG. 2, the wheel 5
is slidable in a guide groove 6 opened in the upper surface 2A of the casing 2 of the box-shaped object 1, and is rotatably attached to one end of a slide piece 7 by a rotating shaft 9. is rotationally driven by a motor 11 provided at the other end of the slide piece 7 via a pinion 12 and a belt 13.

Further, a cylindrical nut portion 14 with a threaded groove formed on the inner surface is provided at approximately the center of the slide piece 7, and is perpendicular to the slide piece 7. A cylindrical screw rod 15 having a screw groove formed on its outer peripheral surface is screwed together.

The screw rod 15 has both ends 15A and 15B rotatably supported on both sides of the casing 2 in the width direction, and is rotationally driven by a motor 17 provided at the inner bottom of the casing 2 via a pinion 18 and a belt 19. be done.

Therefore, the nut portion 14 is reciprocated in the left-right direction in FIG. 2 as the threaded rod 15 rotates, and as a result, the wheel 5 is reciprocated along the width direction of the casing 2.

When the wheel 5 is moved to the right end in FIG. 2, the wheel 5 is set to be located on the center of gravity G of the box-shaped object 1.

In this embodiment, the motors 11 and 17 are configured to be driven by remote control using infrared rays or the like, but since this configuration is conventionally known, a description thereof will be omitted.

Furthermore, a notch 20 is formed at the center in the width direction at the front of the box-like object 1, and the upper surface 2A of the casing 2 at the innermost part of the notch 20
, one end 30A of a rope 30 (described later) is fixed on the center of gravity G of the box-like object 1.

When suspending the box-shaped object 1 configured as described above from the power distribution line 3 using the wheels 5, first, with the wheels 5 spaced apart from the center of gravity G, hang a rope just below the power distribution line 3 as shown in FIG. 30 is suspended from the distribution line 3, and its free end 30B is wound up to form a box-shaped object 1.
Lift vertically upward.

At this time, the width in which the rope 30 swings in the width direction of the box-shaped object 1 is restricted by the notch 20, so that swings, rotation, etc. of the box-shaped object 1 are reduced, and the box-shaped object 1 is lifted smoothly.

In this way, lift the box-shaped object 1 and
4, when the lower height position of the wheel 5 slightly exceeds the upper height position of the distribution line 3, the motor 17 is driven to move the wheel 5 to a position on the center of gravity G. Move to.

Then, when the rope 30 is slightly loosened in this state, the box-shaped object 1 moves downward under its own weight, so that the wheels 5 ride on the distribution line 3 as shown in FIGS. 5 and 6.

As a result, the box-like object 1 is moved to the distribution line 3 by the wheels 5.
be hung in.

As explained above, in this embodiment, the box-shaped object 1
With the wheels 5 moved to a position away from the center of gravity G of
is lifted vertically upward.

Then, when the lower height position of the wheel 5 slightly exceeds the upper height position of the power distribution line 3, the box-shaped object 1
The wheels 5 are moved onto the center of gravity G, and as a result, the box-shaped object 1 is suspended from the power distribution line 3 by the wheels 5. Therefore, the box-shaped object 1 is moved to the distribution line 3 by the wheels 5.
This makes it possible to carry out the work of hanging it extremely easily and rationally.

(Effect) As can be understood from the above explanation, in the box-shaped object hanging device according to the present invention, the height position of the lower part of the wheel is slightly lower than the height position of the upper part of the linear object directly below the linear object. When the box-like object is lifted vertically upward until it passes the box-like object, the wheels are moved onto the center of gravity of the box-like object.

As a result, the wheels are placed on the linear object, and the box-like object is suspended from the linear object by the wheels.

Therefore, the work of suspending a box-shaped object from a linear object using wheels can be carried out extremely easily and rationally.
