Description

The utility model relates to support guide rings intended for the construction of pipeline crossings, mainly with a diameter of 57-377 mm, laid in a protective casing (case) under roads and railways, as well as other engineering structures to protect the insulation coating of the pipeline during its pulling in protective casing, as well as for electrical insulation of the pipeline from the protective casing.

The invention is known from the prior art (RF patent No. 2889056), which relates to the construction of pipeline transport and can be used to drag a pipeline, mainly with a diameter of 57-377 mm, inside a protective casing (case) or other pipe in the construction of crossings under roads and railways . The supporting plastic ring consists of two segments connected to each other, which are made along a radius defined by the outer diameter of the main pipeline and are equipped with fastening and receiving nodes. The receiving unit located at one end of the segment is made in the form of a rectangular groove open on three sides and provided with herringbone teeth on the inner surfaces, and the inlet node is located at the opposite end of the segment and is made in the form of a rectangular plate, on the outer surfaces of which “herringbone” type teeth with an appropriate pitch for fixing in the receiving unit of the second segment when assembling them into a half ring and into a ring.

The disadvantage of this design is that the support ring can only be used for one diameter of the pipeline.

The objective of the claimed utility model is to create a simple in design device that can be used to pull pipelines of two different diameters.

The technical result of the utility model is to reduce the number of equipment for the manufacture of support rings and providing the possibility of pulling through one device pipelines of two different diameters.

The indicated technical result is achieved in the first embodiment of the utility model due to the fact that the support-guide rings for pipelines of two different diameters are assembled from two identical segments, while for pipelines of different diameters, the segments during assembly are oriented differently relative to each other. Each segment of the support-guide ring is made with lodgements on opposite sides of the segment for pipelines of different diameters, the axis of the lodgements in plan being perpendicular to each other, and the surface of the lodgements intersect, forming a through hole in the segment. Segments are made with holes that allow you to assemble segments in pairs using fasteners in support rings for pipelines of two different diameters.

The specified technical result is achieved in the second embodiment of the utility model due to the fact that the support-guide rings for pipelines of two different diameters are assembled from a different number of identical segments for each pipeline diameter, while for pipelines of different diameters, the segments are oriented differently relative to each other during assembly friend. Each segment is made with lodgements on opposite sides of the segment for pipelines of two different diameters, the axes of the lodges are perpendicular to each other in plan, and the surfaces of the lodges intersect, forming a through hole in the segment. Lodges cover pipelines of two different diameters at different angles. Segments are made with holes that allow you to collect segments in the support guide rings for pipelines of two different diameters using fasteners.

 At the same time, due to the different angles of coverage of the lodgements of pipelines of two different diameters, a different number of identical segments is used to assemble the support-guide rings for pipelines of two different diameters.

New in the claimed device is that from the same segments can be assembled support guide rings for pipelines of two different diameters, which reduces the number of accessories for the manufacture of support guide rings, and allows you to use them when pulling pipelines of two different diameters.

The utility model is illustrated by figures 1-6.

Figure 1 shows a General view of the first variant of the segment of the support ring for two different diameters of the pipeline.

Figure 2 shows the assembled design of the support ring from the first variant of the segment for the pipeline of smaller diameter.

Figure 3 shows the assembled design of the support ring from the first variant of the segment for a pipeline of larger diameter.

Figure 4 shows a General view of the second variant of the segment of the support ring for two different diameters of the pipeline.

Figure 5 shows the assembled design of the support ring from the second variant of the segment for the pipeline of smaller diameter.

Figure 6 shows the assembled design of the support ring from the second variant of the segment for a pipeline of larger diameter.

Segment 1 (figure 1) is made with a lodgement 2 for a pipeline of smaller diameter and a lodgement 3 for a pipeline of larger diameter. Lodgments 2 and 3 are made on opposite sides of segment 1.

The supporting-guide ring for a pipe of a smaller diameter (Fig. 2) is assembled from two identical segments 1, using fasteners 4, while the segments 1 during assembly are facing each other with tool holders 2 for a pipe of a smaller diameter.

The support-guide ring for a larger diameter pipeline (Fig. 3) is assembled from two identical segments 1, using fasteners 4, while the segments 1 during assembly are turned to each other with tool holders 3 for a larger diameter pipeline.

Segment 5 (figure 4) is made with a lodgement 2 for a pipeline of smaller diameter and a lodgement 3 for a pipeline of larger diameter. The lodgements 2 and 3 are made on opposite sides of the segment 5. The lodgement 2 covers the pipeline of smaller diameter by 180 °, and the lodgement 3 covers the pipeline of larger diameter by 120 °.

The supporting-guide ring for a pipe of a smaller diameter (Fig. 5) is assembled from two identical segments 5, using fasteners 4, while the segments 5 are assembled facing each other with tool holders 2 for a pipe of a smaller diameter.

The supporting-guide ring for the pipeline of larger diameter (Fig.6) is assembled from three identical segments 5, using fasteners 4, while the segments 5 during assembly are turned to each other with tool holders 3 for the pipeline of larger diameter.

In the General case, the design elements of the device perform the following functions:

- segments 1 and 5 are connected in a support-guide ring around the dragged pipelines of various diameters, serve as a support for the dragged pipeline;

- lodgement 2 of segments 1 and 5 covers a pipeline of smaller diameter;

- lodgement 3 segments 1 and 5 covers a pipeline of larger diameter;

- fasteners 4 connect the segments 1 or 5 in the support guide ring.
