Technical Field
The utility model relates to a tubular product transportation field specifically is a guide tracked transportation structure of mountain area large-scale pipeline.
Background
In the installation process of large pipelines in mountainous areas, the large pipelines are limited by construction terrain and environment, and are difficult to be directly transported to installation positions, and need to be transported for the second time. If the temporary road is built and the large pipeline is transported for the second time by machinery, the construction cost is greatly increased and the environmental protection is not facilitated; and adopt artifical secondary transport, can reduce the efficiency of construction, and have great safety risk among the transportation process.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned defect, provide one kind because of simple structure, rational in infrastructure and simple installation, excellent in use effect's large-scale pipeline secondary transport structure in mountain area, can accomplish the large-scale pipeline transportation in mountain area safely, high-efficiently.
In order to achieve the above object, the present invention is realized as follows:
a guide rail type transportation structure for large pipelines in mountainous areas comprises a winch, two transportation trolleys, a rigid support frame, two channel steel guide rails, a connecting steel wire rope, a traction steel wire rope and a guide rope pulley, wherein the winch is arranged at the top of a secondary transportation section; the channel steel guide rail is two, the central line interval is the same with the large pipeline diameter of transportation and is the same with the pulley interval of travelling bogie, and the channel steel guide rail is laid along rigid support frame upper surface extremely and down in succession, with rigid support frame welded connection, and the cable guide pulley is arranged between two between the channel steel guide rail, with rigid support frame welded connection.
Guide tracked transport structure of mountain area large pipeline, the pipeline clamp internal diameter that constitutes travelling bogie is the same with transportation large pipeline external diameter, paste on the pipeline clamp inner wall and have the rubber layer that the one deck is 2mm thick to increase the friction between clamp and pipeline.
In the guide rail type transportation structure for the large pipeline in the mountainous area, the rigid support frame is erected by adopting steel pipes or section steel, and the strength and the stability of the rigid support frame meet the transportation requirements of the large pipeline.
The guide rail type transportation structure for the large pipeline in the mountainous area has the advantages that the width of the pulley of the transportation trolley is smaller than that of the U-shaped groove of the channel steel guide rail.
The guide rail type transportation structure for the large pipeline in the mountainous area is characterized in that N guide cable pulleys are provided, N is larger than or equal to 1, the first guide cable pulley is arranged at the top end of the rigid support frame, and the guide cable pulleys are arranged every 50m from top to bottom.
The transportation structure is simple in layout, reasonable in structure, simple and convenient to process and manufacture, convenient to install and arrange, and capable of safely and efficiently completing secondary transportation of large pipelines in mountainous areas by using the structure. Adopt the rigidity support frame as the basis of channel-section steel guide rail among the entire structure, utilize the variability of rigidity support frame structure, combine mountain area topography to carry out reasonable adjustment, make this structure can be applicable to the large-scale pipeline secondary transportation of multiple topography. When the rigid support frame is erected, the requirement of erecting the rigid support frame can be met only by locally flattening the terrain with a large gradient or locally hardening the soft soil foundation, the influence of pipeline installation and construction on the environment is reduced to the maximum extent, and the requirement of environmental protection is met.
