Description
Technical field
The invention belongs to passes through engineering machinery field, relates to particularly a kind of major diameter oil transportation, gas transmission, water delivery long distance pipeline and in crossing construction, guarantees that passing through successful intelligent pipeline passes through pusher.
Background technique
Along with increasing rapidly of domestic energy demand, during China " 12 " by newly-built more than 40,000 kilometers of oil and gas pipes.In Construction of Long-distance Pipelines, inevitably to pass through the obstacles such as rivers and lakes.In crossing construction, Directional Drilling, first in predetermined circuit punching, reaming, then carries out pipeline returning.First pipeline is all welded returning before dragging, whole piece returns the pipeline dragging and reaches hundreds of meters.Return to drag and in process, depend merely on Directional Drilling and return and drag, although Directional Drilling is constantly by drilling rod, outside pipeline, mud grouting is to reduce hauling pipe thrust, and reaching the steel pipe of hundreds of meters, to return while dragging resistance quite large.Return that hauling pipe line is longer, diameter is larger, more bad its resistance of stratum condition is larger.Its result often makes Directional Drilling return and drags overburdening, drags motionless or drill rod breaking, makes to pass through project failure, causes very large economic loss.As in July, 2007, Φ 660 pipe passes through in Mou Youjian company in Zhuhai, Guangdong, and during long 500 mitron line, Directional Drilling is due to load overload, could not return how long dragging and drag motionlessly due to load overload, has caused more than 100 ten thousand economic loss.Therefore,, in Pipeline Crossing Program construction, facts have proved that Directional Drilling can not meet the last demand of dragging steel pipe of returning completely, bores back the equipment that drags steel pipe in the urgent need to a kind of auxiliary directional.
Summary of the invention
In order to solve in existing crossing construction Directional Drilling, return and drag steel pipe, especially the overburdening hidden danger that large-diameter steel pipe exists, guarantee is passed through engineering and is carried out smoothly, and the invention provides a kind of the other end at steel pipe to coordinate Directional Drilling jointly to advance the intelligent pipeline of steel pipe to pass through pusher.The invention thrust is large, Qiang Du Gao ﹑ good stability, clamping force are very much not hindered steel pipe protective coating.
The technological scheme that the invention adopts is: intelligent pipeline passes through pusher push action cylinder and is fixed on positioning seat by support, and push action cylinder is connected with thrust disc by track bar; The thrust execution architecture that is formed sealing by thrust framework, positioning and guiding seat and thrust disc; Pull bar one end is connected with thrust disc, and the other end is connected with thrust framework, and some thrust binding clasps are connected with pull bar, and some thrust binding clasps are positioned at respectively in thrust framework, by pulling of pull bar, thrust binding clasp is radially moved in thrust framework; Some clamping cylinders are fixed on positioning and guiding seat; Body folding oil cylinder makes the folding of pusher overall radial; Traveling gear is connected with thrust execution architecture.
Above-mentioned intelligent pipeline passes through pusher, and described thrust binding clasp forms by pressing arc plate and compactor, and one end connection of compactor presses arc plate, and the compactor the other end is connected with pull bar by axle.
Above-mentioned intelligent pipeline passes through pusher, and described pressing on arc plate is covered with protective polyurethane layer.
Above-mentioned intelligent pipeline passes through pusher, is provided with adjusting nut, and adjusting nut is arranged on the front end of thrust disc.
