Smooth type spliced electrical pole

Abstract

The invention discloses a smooth type spliced electrical pole. The smooth type spliced electrical pole comprises a main body pole base, a spliced pole body, a connecting flange, reinforcing ribs, a sliding sleeve and a connecting sleeve, wherein the spliced pole body is arranged on the upper portion of the main body pole base, the connecting flange is arranged at the lower end of the main body pole base and shares the same axis with the main body pole base, the reinforcing ribs are evenly distributed on the inner edge of the main body pole base, the sliding sleeve is fixedly arranged on an inner ring of the bottom end of the spliced pole body, and the connecting sleeve is arranged on the lower portion of the spliced pole body and is connected with an inner ring of the sliding sleeve in a sleeving mode. According to the smooth type spliced electrical pole, splicing and assembling of the main body pole base and the spliced pole body are adopted, installing and transporting speed can be improved, effective transportation in narrow and rugged spaces is convenient, rush repairing time is shortened, and the potential safety hazard for people around is reduced; through the combination of a common shearing disc and a reinforced shearing disc, the anti-shearing strength is improved, pull-crack damages caused by eccentricity are avoided, supplementary anchorage is conducted through the connecting flange, and the stability is improved.

Description

technical field [0001] The invention relates to the technical field of electric power transmission equipment, in particular to a smooth spliced ​​electric pole. Background technique [0002] At present, the overhead lines for power transmission are generally erected with cement poles. In case of natural disasters such as ice and snow, earthquakes, or accidents that cause power poles and broken wires, in order to ensure the rapid recovery of the fault, the power will be dredged as soon as possible and the normal power supply will be restored. However, in mountainous areas where cranes and other transportation vehicles cannot reach, due to the particularity of its terrain and environment, it is not only difficult to erect poles manually, but sometimes it takes more than ten hours or even several hours to erect a pole. day, and because the volume and weight of the utility poles are very large, a single pole even reaches 800 to 900 kg, and the length reaches about 10m, which bri...

[0002] At present, the overhead lines for power transmission are generally erected with cement poles. In case of natural disasters such as ice and snow, earthquakes, or accidents that cause power poles and broken wires, in order to ensure the rapid recovery of the fault, the power will be dredged as soon as possible and the normal power supply will be restored. However, in mountainous areas where cranes and other transportation vehicles cannot reach, due to the particularity of its terrain and environment, it is not only difficult to erect poles manually, but sometimes it takes more than ten hours or even several hours to erect a pole. day, and because the volume and weight of the utility poles are very large, a single pole even reaches 800 to 900 kg, and the length reaches about 10m, which brings a lot of inconvenience to its efficient transportation in a narrow and rugged space, thus further The difficulty and repair efficiency of artificial poles in mountainous areas are exacerbated, and there is an urgent need for an assembled utility pole with a simple structure to facilitate assembly and transportation, reduce the installation process, and reduce the safety hazards to people around

[0003] Steel utility poles are easy to corrode, and the cost of manufacture, processing and maintenance is relatively high. Currently, they are not widely used in China. The compressive strength of concrete materials commonly used in construction is usually only about 100MPa, and the tensile strength is about 10MPa. Traditional utility poles Most of them are ordinary cement utility poles with a small amount of steel skeleton, which are constructed of cement mortar and reinforcing ribs. However, the strength of this utility pole is not high, especially its tensile strength is low. When the crossing line is long and the eccentric force acting on the end of the utility pole is large (such as a corner utility pole, the lines on both sides are asymmetrical, the pole body is prone to cracking and damage, and when a line fault occurs, the defect in shear force More obvious, badly needs enhancement

[0004] Traditional utility poles rely on their own depth for anchoring, and the anchoring effect is greatly affected by the local soil quality. There is no other anchoring means, and they usually work normally. However, under extreme conditions such as strong winds, the stability is too poor, and it is very easy to break the power pole. line failure
