Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 In this invention, when replacing the insulator that suspends the electric line, the electric line is temporarily lifted so that the weight of the electric line is not applied to the insulator, the insulator is removed from the supporting steel, and the replacement work can be performed. For temporary receipt of train lines.

[0002]

[Prior art]

 When replacing insulators on a train line, the insulators cannot be removed unless the suspended weight suspended on the insulators on the train line is temporarily released. For this reason, one end of a lifting machine (trade name: Shimmerer) is hooked directly to the supporting steel near the insulator suspended from a steel pole or other supporting steel, for example, L-shaped steel or H-steel. The hook was hooked on the train line and the lever was rotated to raise the train line.

[0003] In this lifting machine, when the lever is rotated, the chain moves via a ratchet for preventing reverse rotation, and temporarily lifts and lifts the train line.

[0004]

[Problems to be solved by the invention]

 However, in order to suspend such a lifting machine directly on the supporting steel L-shaped steel or H-steel, it must be safely attached to the L-shaped steel or H-steel, and such a tool has not existed conventionally. An object of the present invention is to provide a temporary wire-rail hardware that can securely and easily fix a conventional unstable lifting machine to an L-shaped steel or an H-steel as a supporting steel material and that can be operated safely. is there.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, in the first invention, a U-shaped portion engaging with a supporting steel material extending from a telephone pole or the like, an upper side of the U-shaped portion is extended to be a flat surface, and bolted between the supporting steel material. An aluminum alloy made of a base part having a bolt hole, an inverted triangular support projecting obliquely upward from both ends of the base part, and a suspension part provided downward at the tip of the inverted triangular support. Of the train line.

In the second invention, the upper part of the U-shaped part is extended, and a train wire temporary receiving metal fitting is provided with an inverted triangular support along both sides of a tapered base extension extending upward and forward. (Operation) In the first invention, the U-shaped portion is engaged so as to pinch one side of a supporting steel material extending from a telephone pole or the like, and the supporting steel material and the base portion are bolted to each other by a bolt provided in a bolt hole. As a result, it is possible to reliably fix the entire temporary wire receiving hardware.

Further, the inverted triangular support projecting obliquely upward from both side edges of the base portion operates according to the principle of leverage so that the weight at the tip can be sufficiently received. The suspended portion at the tip bears the weight of the lifting machine and the trolley wire hung on the hook of the lifting machine. When the lever of the lifting machine is rotated, the train line can be lifted by the chain and the ratchet that prevents reverse rotation. Also, since the whole is made of aluminum alloy, the total weight of the temporary wire support hardware is light and the installation work is easy.

In the second invention, since the upper side of the U-shaped portion is extended and the inverted triangular support is provided on both side edges of the tapered base extension projecting forward and upward, the weight is lighter at the tip and the principle of leverage is reduced. The train line can be lifted through the lifting machine.

[0009]

[Embodiment of the invention]

 In the present invention, near the replacement insulator, insert the U-shaped part of the present invention into one side of the L-shaped steel or H steel as the supporting steel, insert a bolt into the bolt hole, and insert the bolt into the supporting steel material. Secure the receiving hardware. Since the present invention is made of aluminum alloy, it is easy to fix lightly and durable. The base extension is firmly fixed to the flat part, and the inverted triangular support extends forward and upward according to the principle of leverage, and can sufficiently support the lifting machine. If the lever of the lifting machine is turned, the electric wire engaged with the hook at the lower end is lifted, the weight of the electric wire hanging on the insulator is released, and the bolt fixing the insulator to the supporting steel is removed and replaced. Be able to work.

 Hereinafter, embodiments shown in the drawings will be described. Fig. 1 is a side view of the temporary wire holder of the present invention, 1 is a main body of the temporary wire holder, 2 is a U-shaped portion, 3 is a supporting steel material extending from a telephone pole or the like, for example, L-shaped steel or H steel. is there. The U-shaped part 2 is engaged with the edge of the supporting steel material 3 and fixed by bolts 4. Reference numeral 5 denotes a base portion, which is a flat surface having the upper side of the U-shaped portion 2 extended, and which is fixed to the supporting steel member 3 with bolts 4 through bolt holes 6. Reference numeral 7 denotes an inverted triangular support, which extends obliquely upward in front of the base portion 5. At the tip of the inverted triangular support 7, a downward suspension 8 is provided.

An inverted triangular support 7 is provided along both sides of a tapered base extension that extends the upper side of the U-shaped portion 2 and projects forward and upward. A lifting machine 10 that lifts an electric line 9 is suspended from the suspension unit 8, and a hook 11 is hooked on the electric line 9. Reference numeral 12 denotes an insulator which suspends a train line at an engagement portion 13.

When the electric line 9 is lifted by the lifting machine 10, the insulator 14 can be separated from the steel material 3 by loosening the bolt 14 on the head of the insulator 12, and the insulator 12 is replaced with a new insulator 12.

[Effect of the invention]

 In the present invention, aluminum alloy train wire temporary holding hardware is fixed to the supporting steel material, a lifting machine is hung on the hanging part at the tip, and the train wire is lifted to remove the weight hanging on the insulator, and it is easy and safe. Insulator replacement work is now possible. In the first invention, a lever wire of a considerable weight can be stably suspended by leverage of the inverted triangle support portion. In the second invention, the obliquely extending portion of the base extension portion is tapered so as to make the leverage action more reliable, and the lifting machine is hooked on the suspension portion provided at the tip of the inverted triangular support on both side edges, and the train is pulled. The wires have been lifted to facilitate insulator replacement work.
