Embodiment Construction

[0019] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0020] like figure 1 Shown is a quick assembly and detachable steel pipeline extrusion shut-off device, which consists of a base 1, a fixed knife edge 2, a movable knife edge 3, a beam 4, a hydraulic cylinder 5, a column 6, a piston 9, a piston rod 10 and corresponding connectors composition. The hydraulic cylinder 5 is composed of a cylinder head 7 and a cylinder body 8 . The base 1, the fixed knife edge 2, the movable knife edge 3, the beam 4, and the hydraulic cylinder 5 are arranged sequentially from bottom to top, and the fixed knife edge 2, the movable knife edge 3 and the beam 4 are parallel to each other. The left and right sides of the plane on the base 1 are vertically inserted with columns 6, and the fixed knife edge 2 and the moving knife edge 3 are arranged between the left and right side columns 6. Fixed knife edge 2 is installed on the base ...

Abstract

The invention discloses a quick assembly and disassembly type steel pipeline extrusion cut-off device. From bottom to top, the quick assembly and disassembly type steel pipeline extrusion cut-off device is sequentially provided with a base (1), a fixed knife edge (2), a movable knife edge (3), a cross beam (4) and a hydraulic cylinder (5), wherein upright columns (6) are perpendicularly inserted in the left and right sides of the plane on the base (1); the movable knife edge (3) is connected to the upright columns (6) in a sliding mode; the hydraulic cylinder (5) comprises a cylinder cover (7) and a cylinder body (8); a piston (9) is arranged in the cylinder body (8) and fixedly connected to a piston rod (10); and the piston rod (10) is inserted into the central hole of the movable knife edge (3) after penetrating through the cylinder cover (7) and the cross beam (4). The invention provides a hydraulic device which has simple structure and is convenient for quick disassembly and assembly and convenient to carry. The quick assembly and disassembly type steel pipeline extrusion cut-off device can be used for salvaging pipeline bursting accidents in the transportation process of large-diameter pipelines, and performs the function of quickly cutting off the pipeline or weakening the medium flow. The quick assembly and disassembly type steel pipeline extrusion cut-off device is a novel salvage device for long-distance pipelines, and is efficient, practical, safe and reliable.

Description

technical field [0001] The invention relates to a hydraulic mechanical device, which can quickly flatten steel pipelines, and is suitable for emergency rapid extrusion and shut-off when large-diameter (DN200-DN500) steel oil (gas) pipelines break and leak. Background technique [0002] Under normal circumstances, the distance between pumping stations of long-distance pipelines is relatively long (100-300km long, 30-50km short). And close the shut-off valve upstream and downstream of the accident point to reduce the leakage of the medium. However, the accident pipeline may be far away from the preset fixed cut-off valve. Even if the valve is closed, there are still a large number of valuable, harmful and dangerous media (such as gasoline, diesel, liquefied petroleum gas and other petroleum products) in the pipeline. Loss will also cause secondary disasters such as fire, explosion, and environmental pollution. Existing various mechanical devices or equipment cannot handle la...
