Abstract
The utility model relates to a construction tool for a long distance transportation pipeline, in particular to an external clamp of a hydraulic tightening pipeline. The external clamp is used for solving the technical problem that the long distance transportation pipeline needs to be clamped before being welded. The construction tool is realized by the following technical scheme that the external clamp of a hydraulic tightening pipeline comprises two hinged semicircular anchor ear racks; the opening and closing end of the anchor ear racks is provided with a hydraulic supporting and pulling device. Compared with the prior art, the external clamp has the advantages of simple structure, reasonable design and high working efficiency and is convenient to carry and use.
Description
Technical field
The utility model relates to a kind of long distance pipeline construction tool, is specially the fastening pipeline external clamp of a kind of hydraulic pressure.
Background technology
Along with the develop rapidly of petrochemical industry, the natural gas consumption constantly increases, and the construction scale of oil and gas pipeline is increasing.The welding of pipeline is the key point of whole construction, and the speed of welding is determining the progress of engineering.For speeding up the work, guarantee to weld the counterpart quality, need a kind of contra-aperture device fast portable, simple to operate.
Summary of the invention
The technical problem of counterpart provides a kind of hydraulic pressure fastening pipeline external clamp to the utility model before the long-distance transportation pipeline welding in order to solve.
The utility model is realized by following technical scheme, and the fastening pipeline external clamp of a kind of hydraulic pressure comprises two hinged semicircular hoop fastening frames, is provided with the hydraulic pressure jacking-drawing device at the folding end of hoop fastening frame.
Operation so then, earlier the hydraulic pressure jacking-drawing device is loosened, the two ends that will need butt-welded two pipelines again, be enclosed between the hoop fastening frame, the primer fluid drawing device that bears down on one closes up two semicircular hoop fastening frames gradually then, the pipeline on both sides is docking together exactly, can carries out welding operation then.
Compared with prior art, the utility model is simple in structure, and is reasonable in design, carries and easy to use high efficiency.Promptly can improve work efficiency and can guarantee to weld the counterpart quality again.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure 1, the 2-hoop fastening frame, 3-link plate, 4-bearing pin, 5-hydraulic pressure jacking-drawing device, 6-pipeline.
The specific embodiment
As schematically shown in Figure 1, the fastening pipeline external clamp of a kind of hydraulic pressure comprises two hinged semicircular hoop fastening frames 1,2, is provided with hydraulic pressure jacking-drawing device 5 at the folding end of hoop fastening frame 1,2.The folding end of a hoop fastening frame 1 is connected with link plate 3 by bearing pin therein, and the folding end of another hoop fastening frame 2 is provided with slideway, and the other end of link plate 3 is connected in the slideway by bearing pin 4, and described hydraulic pressure jacking-drawing device 5 connects bearing pin 4.Described hydraulic pressure jacking-drawing device 5 is a manual hydraulic device.By hoop fastening frame 1,26 pairs in pipeline is lumped together, after involutory end, in the time of need pulling down mouthpart, turn on fuel tap earlier, make 5 pressure releases of hydraulic pressure jacking-drawing device, it is promptly detachable to take link plate again apart.
