Description

[Detailed Description of the Invention] The present invention relates to a tool for attaching and detaching a protective cable cover to and from an overhead cable.

Conventionally, there were no tools for attaching and detaching protective cable covers to overhead cables, so when attaching or removing a cable cover from an overhead cable, it was necessary to open the crack in the cable cover with both hands when attaching or detaching it. was working.

However, this method required a considerable amount of force to be applied at a high place to open the crack, making the work difficult and dangerous.

In view of the above-mentioned problems, the present invention aims to provide a tool that can safely attach and detach protective covers to overhead cables with a small amount of force. A pair of guide strips are provided which have grooves in the longitudinal direction into which the crack edges provided in the grooves can fit, and the guide strips connect the distal ends to each other with the grooves facing outward, and the guide strips connect the distal ends to each other with the grooves facing outward. The rear ends of the guide strips are curved so as to gradually project outward and are connected to each other via a connecting rod, and a fixing rod orthogonal thereto is attached to the upper tip side of the guide strip. The cable cover attaching/detaching tool is characterized in that a grip part is attached to the center of the upper part.

The present invention will be explained below with reference to the drawings. The drawing shows an embodiment of the present invention, in which 1.2 is a pair of semicircular guide strips having semicircular grooves 1a and 2a in the longitudinal direction; The grooves 1a and 2a are turned outward and the leading ends are connected to each other by means such as gluing or welding, and the rear end is curved so as to gradually protrude outward from the joint, and is connected via the connecting rod 3. are connected to each other.

Reference numeral 4 denotes a fixed rod of a predetermined length attached to the upper tip side of the guide strips 1 and 2 so as to be perpendicular thereto; 5 also indicates a fixed rod of the guide strips 1 and 2;
It is a grip part provided at the center of the upper part of the guide strip 2, and is fixed to the distal end side of the guide strips 1 and 2 and the middle of the connecting rod 3 via the legs 5a and 5b.

Note that 10 is a cable cover that is attached to an overhead cable (not shown) through a crack 11, and the grooves la and lb are
The edge 10a of the crack 11 can be fitted into the opening.

Next, a method of using the cable cover attachment/detachment tool constructed as described above will be explained.

First, hold the grip part 5 with one hand, place the tips of the guide strips 1 and 2 into the cracks 11 of the cable cover 10, and fit the edges 10a into the grooves 1a and 2a of the guide strips 1 and 2. and then attach the guide strips 1 and 2 to the cable cover 10.
Push it in toward the opposite end.

Since the rear end sides of the guide strips 1 and 2 are gradually curved outward, the wedge effect creates a crack 11 in the cable cover 10.
As shown in FIG. 3, the opening 12 is pushed outward with a slight force and becomes a large opening 12.

Therefore, by inserting the overhead cable into the cable cover 10 through this opening 12, the cable cover 10 can be attached to the overhead cable.

Also, when removing the cable cover 10 from an overhead cable, the guide strip 1.2 can be pushed into the crack 11 of the cable cover 10 from its tip end, as described above.

During this pushing operation, even if the crack edge 10a is about to come off from the grooves 1a+2a on the tip side of the guide strips 1, 2, the fixing rod 4 will come into contact with the upper edge of the crack 11 of the cable cover 10 and guide the cable cover 10. Since the distal end side of the strip 1.degree. 2 is prevented from falling down, in combination with the wedge effect of the guide strips 1 and 2 described above, the pushing operation can be performed extremely smoothly.

Furthermore, since the guide strips 1 and 2 are semicircular, there is no risk of damaging the outer sheath of the overhead cable during the pushing operation.

As explained above, the cable cover attachment/detachment tool according to the present invention includes a pair of guide strips each having a groove in the longitudinal direction into which a crack edge provided in the longitudinal direction of the cable cover can fit. The leading ends of the guide strips are connected to each other with the grooves facing outward, and the rear ends of the guide strips are curved so as to gradually project outward from the joint and are connected to each other via a connecting rod. A fixed rod is attached to the side and perpendicular to this, and a grip is attached to the center of the upper part of the guide strip, so the overall structure is very lightweight.Moreover, the grip can be grasped to easily move the tip of the guide strip. By simply fitting the edge of the crack in the cable cover into the groove and pushing it in, the crack in the cable cover can be pushed open with a small amount of force, so this type of work at heights can be done easily and safely. There is.

Furthermore, since the edge of the crack fits into the groove of the guide strip during pushing and the fixing rod comes into contact with the upper edge of the crack, the guide strip does not come off from the crack. It also has the advantage of allowing smooth pushing work.
