Description

Telescope-type electric pole {TELESCOPIC ELECTRIC POLE}

The present invention relates to a telescopic pole formed by being fixed so as not to rotate after the multiple overlapped multiple steel pipe members are stepped out.

In general, the pole is to form the pillar of the transmission line, it is made of a monolithic structure of pillar-shaped concrete.

However, this concrete pole has a problem that it takes a relatively large space to lengthen the length of the concrete pole, as well as very difficult to carry and install. In addition, if you want to install the electrical supply accessories, such as insulators after fixing the pole pole, the work must be made at a height, so there was a very dangerous problem in the installation work.

In order to solve this problem, a telescopic pole has been recently proposed in which a plurality of multiple overlapping steel pipe members are drawn out step by step and fixed to prevent mutual rotation.

However, even in such a telescopic pole, there are assembly problems that require fastening numerous fasteners around the outer steel pipe member in order to fix the plurality of steel pipe members so as not to rotate each other. Even if there is a problem that it is difficult to support the load of the electrical pipe installed on the steel pipe member and the pole located in the upper portion of the steel pipe member located on the lower side.

In some cases, a flange is formed on the upper end of the steel pipe member located in the lower part, and a groove is formed around the lower part of the steel pipe member located in the upper part, and then another flange member is inserted into the groove to artificially form a flange and assembled together. Although the configuration has been proposed, this is also difficult to assemble the electric pole due to the artificial flange formation, as well as the load is concentrated on the groove formed around the lower portion of the steel pipe member is installed on the steel pipe members and poles located on the top There was a problem that is difficult to support the load of the electrical installation.

Therefore, the object of the present invention can be made very easy to transport and installation work, in particular a plurality of steel pipe members are assembled and fixed to each other by a simple configuration at the same time the load by the electrical facilities installed on the upper steel pipe members and poles effectively To provide a telescope pole that can be supported.

The object of the present invention described above is located outside the plurality of steel pipe members formed in multiple overlapping to be pulled out in multiple stages and through the lower side of the steel pipe member located on the inner side at the time of maximum withdrawal of the steel pipe member located inside It is achieved by providing a telescopic pole which comprises a fastening member for supporting a steel pipe member located inward as it spans the top of the steel pipe member.

According to a preferred feature of the present invention, the U-shaped locking groove is formed on the upper end of the steel pipe member to which the fastening member spans to prevent left and right rotation of the steel pipe member supported by the fastening member.

According to a more preferred feature of the invention, the fastening member is fastened two horizontally side by side on the top of the steel pipe member.

According to a more preferred feature of the present invention, the outermost steel pipe member of the steel pipe member has a longer length than other steel pipe members so that other steel pipe members can be accommodated in a plurality of overlapping other steel pipe members When they are accommodated therein, the position fixing members are fastened horizontally through the upper and lower portions thereof so that the positions of the multiple overlapping steel pipe members can be fixed. Is displayed.

According to a further preferred feature of the invention, the lower side of the steel pipe member is formed with a fastening hole for penetrating the fastening member, the outer circumferential surface of the steel pipe member at the bottom of the U-shaped locking groove when the multi-step out of the steel pipe member A groove for guiding the drawing direction is formed in the longitudinal direction so that the fastening holes can coincide with each other, and protrusions engaged with the groove protrude inward from the upper ends of the steel pipe members.

In addition, the object of the present invention described above, a plurality of steel pipe members formed to overlap in multiple stages to be pulled out in multiple stages and horizontally penetrates the upper side of the steel pipe member located on the outside when the maximum withdrawal of the steel pipe member located inside It is also achieved by providing a telescoping pole consisting of a fastening member that is supported over the bottom of the lower portion of the steel pipe member located inwardly as fastened.

According to a preferred feature of the present invention, a U-shaped locking groove is formed at the lower end of the steel pipe member that is over the fastening member to prevent left and right rotation of the steel pipe member that is over the fastening member.

According to a more preferred feature of the invention, the fastening member is fastened two side by side horizontally on the upper side of the steel pipe member.

According to a more preferred feature of the present invention, the outermost steel pipe member of the steel pipe member has a longer length than other steel pipe members and other overlapping steel pipe members so as to be accommodated therein other steel pipe members overlapping multiplely When they are accommodated therein, the position fixing members are fastened horizontally through the upper and lower portions thereof so that the positions of the multiple overlapping steel pipe members can be fixed. Is displayed.

According to the telescope poles according to the present invention, as a plurality of steel pipe members overlap multiple to be pulled out in multiple stages, there is an excellent effect that it is very easy to carry and installation can be made very easy.

In addition, a plurality of steel pipe members are assembled and fixed to each other by the fastening member and at the same time, the load by the electric facilities installed on the upper steel pipe member and the pole can be effectively supported, and in particular, the fastening member is supported by the U-shaped locking groove. Accordingly, there is an excellent effect that the left and right rotation of the fastening member can be prevented.

In addition, when the telescope-type electric pole according to the present invention is buried in the ground, there is no need for a base plate, etc., so that the beautiful appearance can be provided.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, which are intended to describe in detail enough to be easily carried out by those skilled in the art to which the present invention pertains.
