Description

Technical Field

[0001] The utility model belongs to the technical field of municipal construction, and in particular relates to a symmetrical tensioning device for HDPE pipeline construction. Background Art

[0002] During the construction of HDPE pipes, since the pipes are long and flexible, a band is usually tied around the corrugations of the HDPE pipes, and then the band is pulled to move the ends of the pipes, so as to facilitate the adjustment of the position during docking. In actual construction, the pipe wall is subjected to a large unilateral tensile force due to the unilateral tensioning of the bands, which often causes deformation of the inner wall of the pipe. In severe cases, cracks may be formed on the inner wall and between the ribs of the HDPE pipe. Therefore, it is necessary to design a symmetrical tensioning device for HDPE pipe construction to solve the above problems. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a symmetrical tensioning device for HDPE pipeline construction, which solves the problem that the HDPE pipeline in the prior art is easily deformed or broken due to uneven force when being moved by pulling with a strap. The device has the characteristics of being able to distribute the stress to an external bracket, avoiding direct stress on the pipeline, and ensuring uniform force when the pipeline moves.

[0004] In order to realize the above-mentioned design, the technical solution adopted by the utility model is:

[0005] A symmetrical tensioning device for HDPE pipeline construction comprises a split upper clamp and a lower clamp, the upper clamp and the lower clamp have the same structure; the upper clamp and the lower clamp are bolted together to form a clamping mechanism with an annular structure and clamped at the corrugations on the outer surface of the HDPE pipeline.

[0006] Preferably, the upper clamp comprises a clamp ring of a semi-annular structure, and one side of the concave surface of the clamp ring is clamped and matched with the corrugations on the outer surface of the HDPE pipe.

[0007] Preferably, both ends of the clamp ring are vertically connected with wing plates, and the surfaces of the wing plates are provided with threaded holes and rope threading holes.

[0008] Preferably, one side of the convex surface of the clamp ring is connected to a frame plate with a U-shaped structure, and the frame plate and the one side of the convex surface of the clamp ring are welded at multiple points.

[0009] Preferably, the upper clamp and the lower clamp are connected to form an integral clamping mechanism by fastening bolts passing through threaded holes; and the frame plates are combined and connected to form a rectangular frame structure.

[0010] Preferably, a draw cord passes through the cord threading hole.

[0011] The beneficial effects of the above-mentioned symmetrical tensioning device for HDPE pipeline construction are as follows:

[0012] The device connects a clamping mechanism to the outside of the pipeline, and drives the pipeline to move by pulling the clamping mechanism through a pull rope, thereby preventing the pull rope from being directly strangled on the pipe wall, causing excessive force on a single point on one side of the pipeline to cause deformation or rupture; the external clamping mechanism can evenly apply stress to the pipe wall through a circular ring, effectively protecting the structure of the pipeline; and the frame plate of the external rectangular structure can provide support for the pipeline and the ground, preventing the pipeline from being damaged by direct friction with the ground during movement.
