Description

Bottom fixing seat for pole erection

technical field

The invention belongs to the technical field of pole erection in power transmission lines, and in particular relates to a bottom fixing seat for pole erection.

Background technique

As we all know, transmission lines play an extremely important role in power systems. Because the erection of transmission lines usually uses utility poles or pylons as supports, and utility poles play a major role in various branch lines, because utility poles Most of them are erected on the side of the road or in other public places, that is to say, they can be seen everywhere; due to the erection of electric poles, it is necessary to install guy wires to ensure the stability of the utility poles, so it is more common to injure people by pulling wires in reports. The current method is to use the wires A thicker safety warning sign is set to remind pedestrians to avoid injury, but some people are still injured by the pull wire, which is usually easily overlooked at night because the pull wire is too thin.

Contents of the invention

In order to solve the problems in the prior art, the object of the present invention is to provide a bottom fixing seat for erecting a utility pole.

In order to realize the above-mentioned purpose of the invention, the present invention adopts the technical scheme as follows:

A bottom fixing seat for pole erection, comprising an upper fixing sleeve, several supporting ribs, a lower fixing sleeve and a fixing plate, the upper and lower fixing sleeves are ring-shaped, and are arranged on the lower end surface of the upper fixing sleeve along the circumferential direction There are several threaded blind holes, and several through holes are arranged on the upper end surface of the lower fixing sleeve, and the threaded blind holes and the through holes correspond to each other one by one, and support ribs are perforated in the corresponding threaded blind holes and through holes , the upper end of the support rib is located in the threaded blind hole, and the lower end of the support rib passes through the through hole.

Further, an annular fixing plate is sheathed on the lower fixing sleeve, and an anchor rod hole is opened on the annular fixing plate through its upper and lower end surfaces, and an anchor rod is pierced in the anchor rod hole.

Further, threads are provided on the outer surface of the upper end of the anchor rod, fastening bolts are screwed on the upper end of the anchor rod, and the fastening bolts are located on the upper surface of the annular fixing plate.

Further, a helical blade is provided on the body of the anchor rod.

Further, threads are provided on the outer surface of the upper ends of the support ribs, and the upper ends of the support ribs are threadedly connected with the threaded blind holes.

Owing to adopting above-mentioned technical scheme, the present invention has the following advantages:

The present invention is pre-buried in the foundation pit, and then the lower end of the utility pole is put into the upper and lower fixing sleeves from top to bottom, and then poured with concrete, and the concrete is connected with the utility pole through the support rib; Due to the functions of the upper and lower fixing sleeves, the invention enables the cement utility pole to obtain the required support strength, thereby avoiding the use of the pull wires and avoiding the occurrence of injury caused by the pull wires.

detailed description

The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1, a bottom fixing seat for erecting a wire pole includes an upper fixing sleeve 1, a number of support ribs 2, a lower fixing sleeve 3 and a fixing plate 4, the upper and lower fixing sleeves are ring-shaped, and the upper and lower fixing sleeves are in the shape of rings. The lower end surface of the fixed sleeve 1 is provided with a number of threaded blind holes along the circumferential direction, and a number of through holes are arranged on the upper end surface of the lower fixed sleeve, and the threaded blind holes and the through holes correspond to each other one by one. Both the hole and the through hole are perforated with support ribs 2, the upper end of the support rib 2 is located in the threaded blind hole, and the lower end of the support rib 2 passes through the through hole.

In order to further improve the stability of the installation of the wire rod, an annular fixing plate 4 is set on the lower fixing sleeve 3, and the fixing plate 4 is provided with an anchor hole 5 passing through its upper and lower end surfaces, and an anchor rod is pierced in the anchor hole 5 6.

The outer surface of the upper end of the anchor rod 6 is provided with threads, and the upper end of the anchor rod is screwed with a fastening bolt 7, and the fastening bolt is located on the upper surface of the annular fixing plate.

A helical blade 8 is arranged on the body of the anchor rod 6 .

The outer surface of the upper end of the support rib 2 is provided with threads, and the upper end of the support rib is screwed to the threaded blind hole through threads.

In the specific application of the present invention, the present invention is pre-embedded in the foundation pit, and then the lower end of the utility pole is put into the upper and lower fixing sleeves from top to bottom, and then poured with concrete, and the concrete is connected with the utility pole through the support rib to form a Integral; and due to the effect of the anchor rod and the upper and lower fixing sleeves, the invention enables the cement pole to obtain the required support strength, thereby avoiding the use of pull wires and avoiding the occurrence of injury caused by the pull wires.
