A special track for transmission line construction and transportation and its construction method

Abstract

The invention relates to a special rail for construction and transportation of power transmission lines and a construction method thereof, comprising a first rail, a connecting rail and a second rail, the bottoms of the first rail, the connecting rail and the second rail are all provided with first support columns, The first support column is provided with a second support column, and the bottoms of the first support column and the second support column are provided with support seats; the first track is provided with a worm rod, and the two ends of the worm rod are connected by bearings and the second support column. A track connection, the worm rod is connected with a driving motor; the upper part of the first track, the connecting rail and the second track is provided with a head and a drag table, and the head and the drag table are respectively provided with a first connecting rod and a second connecting rod. Rod, the first connecting rod and the second connecting rod are hinged, the bottom of the machine head is provided with a first crawler, and the inside of the first crawler is provided with a driving wheel and a guide wheel; The service life is longer, while reducing the fuel consumption of the engine, it can effectively avoid the phenomenon of unstable operation or slipping on the climbing section.

Description

technical field [0001] The invention relates to a special rail for transmission line construction and transportation and a construction method thereof, which are applied in the technical field of transmission line construction equipment. Background technique [0002] As we all know, Fujian's terrain is high in the northwest and low in the southeast, showing a situation of "near the mountains and the sea". The area of ​​mountains and hills in the territory accounts for about 90% of the total area of ​​the province. In order to avoid densely populated areas, EHV and UHV transmission lines are mostly located in mountainous areas with sparse population and poor transportation conditions. For a long time, the reality of power transmission construction sites such as high mountains, steep slopes, and dangerous roads has been unable to change. , the transportation conditions are quite bad. At present, the most used transportation methods are cableway transportation, mule-horse tran...

In order to avoid densely populated areas, EHV and UHV transmission lines are mostly located in mountainous areas with sparse population and poor transportation conditions. For a long time, the reality of power transmission construction sites such as high mountains, steep slopes, and dangerous roads has been unable to change. , the transportation conditions are quite bad

At present, the most used transportation methods are cableway transportation, mule-horse transportation, and crawler-type transportation. If it encounters a rainy day, it will affect the transportation of construction materials and thus affect the project schedule; crawler transportation needs to build a flat road before transportation, and has high requirements for the transportation site, especially when climbing In the lot, once the brake is insufficient or the brake is unstable, it will have poor climbing ability, inability to stop or slip after a long time of use, and there is a large difference in speed between uphill and downhill, and it is prone to malfunction during operation. Problems such as stability or even engine flameout, which lead to risks in transportation and low work efficiency
