Embodiment Construction

[0020] Such as Figure 1-4 As shown, the intelligent pipeline traverses the propulsion machine, which consists of a positioning seat (1), a bracket (2), 2 thrust cylinders (3), 24 thrust clamps (4), tie rods (5), and thrust frame (6) , Positioning guide seat (7), 8 clamping cylinders (8), thrust plate (9), walking device (10), 2 body opening and closing oil cylinders (11) and thrust rod (12).

[0021] The two thrust cylinders (3) are respectively hinged on both sides of the positioning seat (1) through the bracket (2), and can swing up and down with the steel pipe (15). The thrust cylinder (3) drives the thrust plate (3) through the thrust rod (12). 9) Exercise.

[0022] A closed thrust execution structure is composed of a thrust frame (6), a positioning guide seat (7) and a thrust plate (9). Make the overall force reasonable, uniform and high strength.

[0023] A total of 4 tie rods (5) are arranged, two symmetrically arranged on both sides of the steel pipe, one end of the tie ro...

Abstract

The invention relates to an intelligent pipeline crossing pusher. The technical scheme is as follows: a thrust cylinder is fixed on a positioning base through a support and connected with a thrust plate trough a thrust rod; a thrust frame, a positioning guide base and the thrust plate constitute a closed thrust execution structure; one end of a pull rod is connected with the thrust plate, and the other end is connected with the thrust frame; a plurality of thrust clamping devices are connected with the pull rod, positioned in the thrust frame respectively and moved radially in the thrust frame through pulling of the pull rod; a plurality of clamping cylinder are fixed on the positioning guide base; the whole pusher is opened and closed radially by body opening and closing cylinders; and a traveling device is connected with the thrust execution structure. The pusher is simple in structure and convenient to operate, a steel pipe ejector sleeve is clamped at one end of a steel pipe, and the pusher cooperates with a directional drill to drag back the steel pipe synchronously in a pull and push manner.

Description

technical field [0001] The invention belongs to the field of crossing engineering machinery, and in particular relates to an intelligent pipeline crossing propulsion machine for ensuring successful crossing of large-diameter oil, gas and water long-distance pipelines during crossing construction. Background technique [0002] With the rapid growth of domestic energy demand, my country will build more than 40,000 kilometers of oil and gas pipelines during the "Twelfth Five-Year Plan" period. In the construction of long-distance pipelines, it is inevitable to cross obstacles such as rivers and lakes. In crossing construction, directional drilling first drills and reams holes on the predetermined route, and then drags back the pipeline. All the pipelines are welded before being towed back, and the entire pipeline to be towed back is hundreds of meters long. During the pull-back process, the pull-back of the directional drill alone is used. Although the directional drill conti...
