Description

Technical Field

[0001] The utility model belongs to the field of heating pipeline construction, in particular to a detachable steel pipeline orifice blocking device. Background Art

[0002] In the construction of heating network pipelines, as the construction progress changes, the sealing of pipeline openings is also a very important process. The pipeline sealing process is mainly to prevent people, animals, etc. from entering the pipeline by mistake, thus causing safety hazards. At the same time, it can prevent a large amount of water and silt and other debris from entering the pipeline during rainy weather, which will bring great hidden dangers to the subsequent heating construction and operation work.

[0003] At present, the conventional method of pipe plugging is: after the pipe welding is completed every day, a steel plate is temporarily spot welded on the pipe mouth for temporary plugging. However, when the construction is carried out the next day, the pipe mouth needs to be repeatedly welded, cut, and polished, which is time-consuming and labor-intensive, and will also affect the subsequent welding quality. In addition, there are some other plugging devices, which have a complex structure and a high cost, and are not suitable for use in actual heating pipe installation projects. Utility Model Content

[0004] In view of the problems existing in the existing thermal pipeline blocking devices, a detachable steel pipeline orifice blocking device is proposed. The utility model is easy to operate and has a good blocking effect. It can block the pipe orifice efficiently and environmentally friendly without damaging the original pipeline, which greatly saves time and labor costs.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a detachable steel pipe orifice plugging device, comprising an insulation pipe, an annular clamp is arranged on the insulation pipe, the annular clamp is detachably fixed on the outside of the insulation pipe, a plugging steel plate is arranged at the pipe orifice of the insulation pipe, and the plugging steel plate and the annular clamp are connected by a plurality of buckles;

[0006] The buckle includes an upper screw, a connecting piece and a lower connecting rod. The upper screw passes through a first mounting hole preset on the blocking steel plate and a second mounting hole preset on the connecting piece in sequence and is then fastened with a nut. One end of the lower connecting rod is connected to a hanging plate preset on the annular clamp, and the other end of the lower connecting rod passes through a third mounting hole preset on the connecting piece and is then fastened with a nut.

[0007] Furthermore, the annular clamp includes at least two arc clamps, both ends of the arc clamps are provided with connecting pieces, and the connecting pieces of adjacent arc clamps are butt-jointed and fastened by bolts.

[0008] Furthermore, the number of the arc-shaped cards is three or four.

[0009] Furthermore, the hanging plate is welded and fixed to the outer surface of the annular clamp, and a hanging hole connected to the lower connecting rod is opened in the middle of the hanging plate.

[0010] Furthermore, the first mounting holes are oblong holes, and the first mounting holes are evenly distributed in a ring shape on the blocking steel plate.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the utility model uses a buckle to connect the plugging steel plate and the annular clamp together, so that the plugging steel plate is buckled at the pipe mouth, and the pipe mouth is blocked by the plugging steel plate. The entire device does not require the original thermal pipeline, and the buckle, the plugging steel plate, and the annular clamp are all detachably connected and can be recycled. At the same time, the components used are all bolts, steel plates and other materials commonly found on construction sites, and the cost is low.

[0012] In addition, the plugging device of the utility model has the advantages of easy operation, good plugging effect, wide application range, etc. By replacing the annular clamps and plugging steel plates of different diameters, it can effectively cope with the plugging of pipe openings of various pipe diameters.

DETAILED DESCRIPTION

[0019] like Figure 1-Figure 4 As shown, a detachable steel pipe orifice plugging device includes an insulation pipe 1. As the object to be plugged, the degree and effect of its orifice plugging will directly affect its subsequent use effect. An annular clamp 2 is provided on the insulation pipe 1, and the annular clamp 2 can be detachably fixed on the outside of the insulation pipe 1. The size of the clamp is determined according to the size of the outer diameter of the insulation pipe 1, and the clamp is fastened to the outer surface of the steel pipe with bolts.

[0020] The annular clamp 2 includes at least two arc clamps 21, and both ends of the arc clamps 21 are provided with connecting pieces 22. The connecting pieces 22 of adjacent arc clamps 21 are connected and fastened by bolts. The number of arc clamps 21 is selected according to the outer diameter of the insulation pipe 1. For the insulation pipe 1 with a large diameter, four arc clamps 21 can be used for connection.

[0021] A plugging steel plate 23 is provided at the pipe opening of the insulation pipe 1. Usually, the plugging steel plate 23 is about 20 mm larger than the outer diameter of the steel pipe. There are prefabricated oblong holes around the plugging steel plate 23 for installing the clips 4. The clips are fixed on the surface of the steel pipe 10-20 cm away from the pipe opening. The plugging steel plate 23 is connected to the annular clip 2 by multiple clips 4.

[0022] The buckle 4 is the main component connecting the annular clamp 2 and the sealing steel plate 23. We need to determine the number of buckles 4 according to the size of the insulation pipe 1. The larger the pipe diameter, the more buckles 4 are configured. The position of the buckle 4 is mainly at the same position of the sealing steel plate 23 and the clamp, and it is installed evenly according to the size of the pipe diameter.

[0023] like Figure 1 As shown, the buckle 4 includes an upper screw rod 41, a connecting piece 42 and a lower connecting rod 43. The upper screw rod 41 passes through the first mounting hole 31 preset on the blocking steel plate 23 and the second mounting hole 421 preset on the connecting piece 42 in sequence and is fastened with a nut. The upper screw rod 41 connects the blocking steel plate 23 and the connecting piece 42 together.

[0024] One end of the lower connecting rod 43 is similar to a hook, and the other end is a screw. One end of the hook of the lower connecting rod 43 is connected to the hanging plate 5 preset on the annular clamp 2, and the other end of the lower connecting rod 43 passes through the third mounting hole 422 preset on the connecting member 42 and is fastened to the nut. The size of the upper screw 41 and the lower connecting rod 43 is determined according to the distance between the connecting member 42 and the blocking steel plate 23 and the annular clamp 2.

[0025] In addition, the hanging plate 5 is welded and fixed to the outer surface of the annular clamp 2, and a hanging hole connected to the lower connecting rod 43 is provided in the middle of the hanging plate 5. It is possible to ensure that there is at least one hanging plate 5 on each arc clamp 21, so that the whole device can be balanced.

[0026] In terms of application, the utility model has the advantages of simple plugging operation, good plugging effect, and wide application range. The pipe opening can be efficiently and environmentally friendly plugged without damaging the original pipeline, greatly saving time and labor costs. The plugging device used in this study can be recycled, which meets the advantages of environmental protection and material saving, and can effectively cope with the plugging of pipe openings of various diameters.

[0027] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
