Abstract

PROBLEM TO BE SOLVED: To easily mount and demount a cover and to surely protect the glass by connecting a glass cover of two-split structure by a pin at one side of a divisin part to obtain an open-close structure, covering a peripheral edge part and a backside of a ceramics part of the glass with the cover, and fixing the cover by a locking means at an open-close side. SOLUTION: A hole for inserting a pin of the glass is formed on a center of an almost circular bottom part 2, an upper end of a side wall 3 formed by standing a peripheral edge of the bottom part 2 is slightly converged inside, further the whole body is divided into two, they are jointed by a pin 4 at one side to obtain an open-close structure, a locking means 5 is mounted at an open-close side, and a notch 6 is formed on a part of an upper end of the side wall 3 to expose a glass mark. This glass cover 1 for construction having two- split structure is opened around the pin 4, the cover 1 is mounted on the glass on the ground, the bottom part 2 is contacted with a bottom of the glass ceramic part, and the cover is closed to fit the side wall 3 to the peripheral edge part of the ceramic part, and to fix the same by a locking means 5. Whereby the contamination and the damage of the glass when it is mounted on a steel tower can be surely prevented by using this glass cover 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction insulator cover useful for assembling and transporting an insulator used for an overhead transmission line.

[0002]

2. Description of the Prior Art Insulators for overhead power transmission lines, particularly insulator series, are constructed by connecting a predetermined number of insulators on the ground as shown in FIG. At this time, the adjacent insulators may come into contact with each other, or may come into contact with metal fittings on the ground or on a steel tower, thereby damaging the porcelain portion of the insulator.

[0003]

Conventionally, an insulator mat has been used to protect the insulator, and the insulator mat is laid on the construction site to protect the insulator from the ground. At the time of installation of the device on the steel tower, it was not possible to prevent the contamination caused by rainwater and the damage caused by the contact between the insulators and the metal fittings. After installation of the device on the tower, replacement and cleaning of the defective insulator is very time-consuming.

Therefore, the problems to be solved by the present invention (objects)
An object of the present invention is to provide a detachable construction insulator cover that can surely protect the insulator in view of the above-mentioned problems of the related art.

[0005]

A construction insulator cover provided by the present invention has a two-part structure, and is provided with an opening / closing structure by joining pins on one side of a divided part, and having a locking means on the opening / closing side. It is.

[0006] The cover is shaped so as to cover the peripheral portion and the back (fold) side of the porcelain portion of the insulator, and it is preferable to provide a cutout in the portion covering the peripheral portion so that the insulator mark can be exposed.

[0007]

FIG. 1 shows an embodiment of a construction insulator cover according to the present invention, wherein (a) is a side surface, (b) is a bottom surface,
(C) shows an open plane, and (d) shows a closed plane. Fig. 2 shows an example in which the above-mentioned construction insulator cover is covered. (A) is a side face on the insulator mark side, (b) is a perspective bottom view looking up from below, and (c) is a view looking down from above. Each of the perspective planes is shown.

The construction insulator cover of this embodiment has the shape shown by reference numeral 1 in FIG. 1 and has a substantially circular bottom portion 2 having a hole formed in the center, and a rising upper end at the periphery of the bottom portion 2. It is shaped with the side wall 3 converging slightly inside, and the whole is divided into two parts, and it is joined with the pin 4 on one side of the divided part, and there is no structure that can be opened and closed as shown in FIGS. And locking means 5 on the open / close side. A cutout 6 is provided in a part of the upper end of the side wall 3 in relation to an insulator mark described later.

The construction insulator cover 1 of this embodiment is laid on the ground as shown in FIG. 2 and is used for packing the transportation for the insulator attached to the steel tower at the stage of the terrain where the soiling and damage are increased. Attach when unraveled.

The construction insulator cover 1 is placed on the insulator in an open state as shown in FIG. 1 (c), and is simply closed as shown in FIG. 1 (d) to complete the attachment to the insulator. After the installation, as shown in FIG.
With the pin 11 passed through, the side wall 3 is fitted to the peripheral portion of the porcelain portion 12 of the insulator 10 and is fixed to the insulator 10 and locked by the lock means 5 so as not to open. .

The construction insulator cover 1 mounted as described above covers the bottom and folds of the insulator porcelain portion 12 with the bottom portion 2, and covers the peripheral portion of the insulator porcelain portion 12 with the side wall 3. At the edge of the porcelain part and the fold part which are easily damaged.

As described above, the construction insulator cover 1 that covers the insulator 10 is configured as an insulator device by aligning the notch 6 with the position of the insulator mark 13 (as shown in FIG. 3).
It is possible to correct the mark position after assembling.

After assembling the insulator to which the construction insulator cover 1 has been attached as shown in FIG. 3 and mounting it on a steel tower, the construction insulator cover 1 is removed simply by removing the locking means 5 of the construction insulator cover 1. Can be removed. The removed construction insulator cover can be reused.

[0014]

According to the present invention as described above, the desired object (object) of providing a detachable construction insulator cover capable of reliably protecting the insulator can be attained. The effect is great.
