Special die for concrete electric pole convenient to construct and production process

Abstract

The invention relates to the technical field of concrete electric poles, and discloses a special die for a concrete electric pole convenient to construct and a production process. The die comprises anupper pole steel die and a lower pole steel die, wherein the upper pole steel die comprises an upper pole concave cavity and an upper pole protruding column, and the lower pole steel die comprises alower pole concave cavity and a lower pole protruding column. The production process comprises the following steps of: producing an upper pole through the upper pole steel die by using an upper pole production line, producing a lower pole with a hollow inner cavity through the lower pole steel die by using a lower pole production line, and placing the upper pole into the hollow inner cavity of thelower pole by utilizing an assembling production line to obtain a finished electric pole product. The special die can be used to reliably, conveniently and efficiently produce the concrete electric pole with the advantages of being flexible in height adjustment, convenient to construct and maintain and high in structural strength and saving transportation space.

Description

technical field [0001] The invention relates to the technical field of concrete electric poles, in particular to a special mold for concrete electric poles with convenient construction and a production process. Background technique [0002] In order to facilitate the processing and transportation of concrete poles, concrete pole manufacturers generally process longer concrete poles in sections for transportation and on-site assembly. The butt joint of the steel ring is fixed by welding, but it is prone to misalignment, welding deformation, and pole end bending after assembly, and the welded part of the pole is easy to rust and rot after long-term use, and the durability is not strong and there is drop In addition, there are many construction tools that need to be carried, which is not conducive to carrying and on-site deployment. The construction steps are also complicated and cumbersome, which is not conducive to high-efficiency construction on site; [0003] The patent do...

AI Technical Summary

Problems solved by technology

[0004] Although the flange design of the above scheme can ensure faster assembly process and more stable structure after assembly, due to problems such as the structural design of the sectioned pole structure, it is impossible to use a static press to press the pole deep into the ground and erect the pole. During the process, the conventional process of digging, poles, filling and compaction is still required, which greatly affects the efficiency of pole erection; during transportation, although the difficulty of transportation and the length of the transport vehicle can be reduced by segmentation, it cannot save transportation space; In addition, once the concrete pole is erected, on the one hand, the height of the concrete pole after erection cannot be reasonably adjusted according to the national standard requirements of the lowest point of sag of the erected wire, unless the concrete pole is pulled out and the concrete pole is readjusted. The height of the ground surface and the distance between two concrete poles; on the other hand, when the ground surface at the point where the concrete poles are erected partially sinks, the height can be flexibly changed to ensure that the lowest point of the wire sag meets the national standard requirements
