Description

Technical Field

[0001] The utility model relates to the field of PE pipeline installation, and particularly relates to a PE pipeline limiting device. Background Art

[0002] During the installation of PE pipelines, considering that PE pipelines are light in weight and easy to deform, the pipelines will float due to buoyancy during the concrete pouring process, and the pipelines will not be installed straight due to pipeline deformation during the installation process, and subsequent manual adjustment is required. Currently, there is no special tool for pipeline limiting, and manual adjustment and control are required, resulting in low work efficiency and poor effects. Summary of the Utility Model

One end of the first cross beam is provided with a first threaded column, and one end of the second cross beam is provided with a second threaded column. The first threaded column moves up and down relative to the first cross beam, and the second threaded column moves up and down relative to the second cross beam. A number of first limiting columns are movably arranged on the bottom surface of the first cross beam, and a number of second limiting columns are movably arranged on the bottom surface of the second cross beam.

[0006] Further, the first cross beam and the second cross beam are of a hollow structure, and a limiting groove is arranged at the bottom. The first limiting column or the second limiting column includes an upper top plate and a support column, and the upper top plate is clamped in the limiting groove, and the support column extends downward.

[0007] Further, a number of threaded holes are arranged on the top plate of the second cross beam, and first bolts are arranged in the threaded holes to limit the relative movement of the first cross beam and the second cross beam through the first bolts.

[0008] Further, threaded holes are respectively arranged on the side surfaces of the first cross beam and the second cross beam, and second bolts are arranged in the threaded holes to fix the first threaded column and the second threaded column through the second bolts.

[0009] Further, the sizes and heights of the first limiting column and the second limiting column are adjustable to match different application scenarios.

[0010] Further, arc-shaped grooves are arranged at the bottoms of the first limiting column and the second limiting column. When in use, the PE pipe is limited in the arc-shaped grooves to prevent the PE pipe from moving and being damaged.

[0011] Advantageous technical effects of the present invention:

[0012] The present invention provides a PE pipe limiting device. When in use, first adjust the first cross beam and the second cross beam to an appropriate width so that the first threaded post and the second threaded post are closely arranged side by side against both sides of the PE pipe, and fix the first cross beam and the second cross beam through the second bolt. Then insert the first threaded post and the second threaded post into the soil, and adjust the heights of the first cross beam and the second cross beam so that the first limiting post and the second limiting post tightly clamp the PE pipe and fix the first limiting post and the second limiting post through the first bolt. Clamp the PE pipe in the above way to prevent the pipe from floating during the concrete pouring process. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1

[0022] See Figures 1-5, a PE pipe limiting device, including a first cross beam 1 and a second cross beam 2. In this embodiment, both the first cross beam 1 and the second cross beam 2 are hollow square pipe structures, and the size of the second cross beam 2 is smaller than that of the second cross beam 2. Therefore, the second cross beam 2 can be inserted into the first cross beam 1 and move within the first cross beam 1.

[0023] One end of the first cross beam 1 is provided with a through threaded hole, and a first threaded post 3 is arranged in the threaded hole. The first threaded post 3 can move up and down relative to the first cross beam 1. A threaded hole is provided on the front side surface of the first cross beam 1, and a first bolt 10 is arranged in the threaded hole. When it is not necessary to move the first threaded post 3, the first threaded post 3 is fixed by the first bolt 10.

[0024] One end of the second cross beam 2 is provided with a through threaded hole, and a second threaded post 4 is arranged in the threaded hole. The second threaded post 4 can move up and down relative to the second cross beam 2. A threaded hole is provided on the front side surface of the second cross beam 2, and a second bolt 11 is arranged in the threaded hole. When it is not necessary to move the second threaded post 4, the second threaded post 4 is fixed by the second bolt 11.

[0025] Limiting grooves 9 are provided on the lower bottom plates of the first cross beam 1 and the second cross beam 2. A first limiting post 5 is arranged in the limiting groove 9 of the first cross beam 1, and a second limiting post 6 is arranged in the limiting groove 9 of the second cross beam 2. The first limiting post 5 and the second limiting post 6 include an upper top plate 7 and a support post 8. The upper top plate 7 is clamped in the limiting groove 9, and the support post 8 extends downward.

[0026] See Figure 6 , in this embodiment, an arc groove 12 is provided at the bottom of the support post 8 to match the cylindrical PE pipe. During use, the PE pipe is limited in the arc groove 12 to prevent the PE pipe from moving and being damaged.

[0027] During the actual use process, the sizes of the first limiting post 5 and the second limiting post 6 can be adjusted to facilitate matching PE pipes with different diameters.

[0029] A number of threaded holes are provided on the upper top surface of the second cross beam 2, and first bolts 10 are arranged in the threaded holes. The relative movement between the first cross beam 1 and the second cross beam 2 is restricted by the first bolts 10.

[0030] The usage process of the present utility model is as follows: When in use, first adjust the first crossbeam 1 and the second crossbeam 2 to an appropriate width, with the first threaded column 3 and the second threaded column 4 closely attached to and arranged parallel to both sides of the PE pipe, and fix the first crossbeam 1 and the second crossbeam 2 through the second bolt 11. Then insert the first threaded column 3 and the second threaded column 4 into the soil, adjust the height of the first crossbeam 1 and the second crossbeam 2, so that the first limiting column 5 and the second limiting column 6 tightly clamp the PE pipe and fix the first limiting column 5 and the second limiting column 6 through the first bolt 10. Clamp the PE pipe in the above manner to prevent the pipe from floating during the concrete pouring process.
