Technical field:
The utility model relates to a pipeline protection device, in particular to a pipeline protection ring, which is used for isolating and protecting pipelines when oil pipelines, gas pipelines, common steel pipes and other metal pipelines are stacked in an oil field.
Background art:
The outer layers of oil pipelines, gas pipelines and many other pipelines in oil fields are treated with anti-corrosion and coated with protective layers. If pipelines are not isolated and protected during transportation, they will rub against each other, which will easily damage the protective layer on the surface and affect the service life of pipelines.
Summary of the invention
The invention aims to overcome the shortcomings of the prior art and provide a pipeline protection ring which is convenient to use and labor-saving to operate, and can effectively protect oil pipelines, gas pipelines, common steel pipes and other metal pipelines in the oil field.
The purpose of the invention is realized by the following technical scheme: two arc-shaped strips are connected end to end to form a ring, one joint of the arc-shaped strips consists of a clamping groove and a clamp extending into the clamping groove, and the other joint consists of a mortise and a tenon embedded in the mortise, or the joints of the arc-shaped strips all consist of mortises and tenons embedded in the mortise; The card slot and the card extending into the card slot are provided with holes, the connector is located in the holes, the card slot and the card are fixedly or movably connected, and the mortise and tenon are embedded. From the above description, it can be seen that the utility model has the following advantages: firm connection, not easy to fall off, convenient to put on and take off the pipeline, greatly reducing the labor intensity of users, and effectively protecting the surface layer of the pipeline.
Fig. 1 is a structural schematic diagram of the utility model, fig. 2 is a sectional view of the connection between the card and the card slot in fig. 1, fig. 3 is another structural schematic diagram of the utility model, and fig. 4 is a concrete embodiment of the arc bar structural diagram in fig. 3.
The utility model will be further described with the attached drawings, as shown in figure 1. The pipeline protection ring is formed by connecting two arc-shaped strips 2 end to end to form a ring. The arc-shaped strip 2 has two connectors, one of which consists of a card slot 3 and a card 4 extending into the card slot 3, as shown in fig. 2, and the other consists of a mortise 6 and a tenon 5 embedded in the mortise 6. There are holes in the card slot 3 and the card 4 extending into the card slot 3, and the connector 1 is a rivet located in the hole for fixedly connecting the card slot 3 and the card 4. The mortise 6 and the tenon 5 embedded in the mortise 6 are provided with holes, the bolt is located in the holes, and the mortise 6 and the tenon 5 are movably connected. When in use, two arc-shaped strips 2 fixedly connected by the card slot 3 and the card 4 are sleeved on the pipeline to be protected, the tenon 5 of the mortise 6 at the other end of the arc-shaped strips 2 is butted, the tenon 5 is embedded in the mortise 6, and the connector/kloc-0 is inserted into the butting hole of the tenon 5 of the mortise 6, so that the pipeline protection ring is firmly sleeved on the pipeline to be protected, which is convenient for transportation and stacking; When the protective ring on the pipeline needs to be untied, the protective ring can be removed from the pipeline only by pulling out the pins on the mortise 6 and tenon 5, without any tools, and it is very convenient to put on and take off.
As shown in fig. 3, the pipeline protection ring consists of two arc-shaped strips 2 connected end to end, and the structure of one arc-shaped strip is shown in fig. 4. The arc-shaped strip 2 has two connectors, both of which are composed of a mortise 6 and a tenon 5 embedded in the mortise 6. The mortise 6 and the tenon 5 embedded in the mortise 6 have holes, the connector 1 is located in the holes, and the mortise 6 and the tenon 5 are fixedly or movably connected. The connector 1 of one connector is a rivet, and the connector 1 of the other connector is a wire. When in use, two arc-shaped strips 2 connected with tenons 5 and mortises 6 through rivets are sleeved on the pipeline to be protected, the tenons 5 of mortises 6 at the other ends of the arc-shaped strips 2 are butted, the tenons 5 are embedded in the mortises 6, the connector/kloc-0 is inserted into the butting holes of the tenons 5 of the mortises 6, and the lines are hinged, so that the pipeline protection ring can be firmly sleeved on the pipeline to be protected, which is convenient for transportation and stacking; When the protective ring on the pipeline needs to be untied, the protective ring can be removed from the pipeline only by screwing the iron wire on the mortise 6 and tenon 5, which is very convenient.
