A series combined concrete utility pole

Abstract

The invention belongs to the technical field of power supply engineering, and particularly discloses a series combination type concrete utility pole. The series combination type concrete utility pole comprises an upper pole body and a lower pole body, wherein the upper pole body is slidably connected with the lower pole body; a pair of arc-shaped first guide grooves arranged in a splayed mode are formed in the side wall of the upper pole body, and a trapezoidal protrusion is arranged at the bottom end of the upper pole body; a pair of symmetrically arranged groove-shaped second guide grooves are formed in the upper side wall of the lower pole body; supporting blocks with sliding grooves are fixedly connected to lower end openings of the second guide grooves, and the lower ends of the second guide grooves communicate with the sliding grooves; ejecting blocks sleeve the sides, near the center of the lower pole body, of the sliding grooves, and the ejecting blocks are slidably connected with the sliding grooves; inclined surfaces parallel to the side surface of the trapezoidal protrusion are arranged on the right sides of the ejecting blocks; and the second guide grooves are internally and slidably connected with elastic inserting strips. According to the series combination type concrete utility pole, the upper ends of the elastic inserting strips are inserted into the first guide grooves to clamp the upper pole body, so that the stable and firm connection between the upper pole body and the lower pole body is ensured.

Description

technical field [0001] The invention belongs to the technical field of power supply engineering, in particular to a series combined concrete utility pole. Background technique [0002] Telephone poles are bridges for electricity, allowing electricity to be transported to various places. The common telegraph poles we have are wooden poles and cement poles. There are many general types of utility poles, such as: concrete utility poles are utility poles made of concrete and steel bars or steel wires. Iron poles: utility poles made of pig iron, concrete utility poles are prestressed and non-prestressed. The cross-section of the utility pole has square, octagonal, I-shaped, ring or other special-shaped cross-sections. The most commonly used are circular cross-section and square cross-section. [0003] The transmission lines in mountainous areas are generally arranged along mountain roads, and the utility poles are installed on one side of the road. The mountain roads are narro...
