Description

Technical Field

[0001] This utility model relates to a pipe clamp, belonging to the field of gas pipeline construction technology. Background Technology

[0002] Gas pipeline construction refers to the entire process of transforming a gas transmission and distribution system from blueprints into a physical facility, in accordance with engineering design requirements and relevant specifications. It encompasses a series of technical activities, from material preparation and pipeline laying to connection, system testing, and acceptance. Its core objective is to safely and efficiently construct gas transmission channels to ensure long-term stable operation.

[0003] During the construction of gas pipelines, thermal expansion and contraction caused by temperature changes can lead to a series of technical problems. For example, L-shaped or Z-shaped bends may not be able to absorb sufficient displacement, or the corrugated compensator may be selected incorrectly. For instance, if the axial compensator is used for lateral displacement or is not installed properly, the pipeline may expand when the temperature rises, which may generate axial thrust or lateral bending. This can cause the thermal compensation of the pipeline to fail, resulting in deformation of the support, cracking of the weld, or leakage of the flange.

[0004] In summary, during the construction of gas pipelines, there is a technical problem that the pipeline expands when the temperature rises, which may generate axial thrust or lateral bending, leading to the failure of the gas pipeline's thermal compensation. Utility Model Content

[0005] This invention aims to solve the technical problem of gas pipeline thermal compensation failure caused by pipeline expansion due to temperature rise during construction, which may generate axial thrust or lateral bending. Therefore, it provides a pipeline clamp comprising an upper shell, a lower shell, a sleeve clamp, a locking bolt, and an adjusting bolt.

[0006] The upper shell is an L-shaped plate, and the lower shell is an inverted L-shaped plate. The bottom end of the upper shell is hinged to the right end of the lower shell. A connecting plate is provided at the left end of the upper shell. The connecting plate and the left side plate of the lower shell are both provided with corresponding threaded holes. The locking bolt is detachably connected to the threaded holes. The connecting plate and the lower shell are detachably connected by the locking bolt. Sleeve clamps are installed in the middle of the inner side walls of the upper and lower shells. Through holes are provided on the upper side plate and the right side plate of the upper shell. The adjusting bolt is connected to the sleeve clamp through the through holes.

[0007] As another improvement of this utility model, the sleeve clamp includes an upper tube, a lower tube and a spring. The lower tube is fitted on the lower part of the outer side of the upper tube and has a concave arc-shaped clamping surface. One end of the spring is fixedly connected to the upper tube and the other end of the spring is fixedly connected to the lower tube.

[0008] As another improvement of this utility model, the upper tube includes an inner cylinder and an outer cylinder. The outer cylinder is fitted on the outside of the inner cylinder. A threaded hole is opened on the top surface of the outer cylinder. The end of the adjusting bolt passes through the through hole and the threaded hole and abuts against the upper surface of the inner cylinder.

[0009] As another improvement of this utility model, the concave arc-shaped clamping surface matches the shape of the external gas pipeline surface.

[0010] As another improvement of this utility model, an anti-slip pad is fixedly installed on the lower surface of the clamping surface of the lower tube.

[0011] As another improvement of this utility model, the anti-slip pad is made of rubber.

[0012] As another improvement of this utility model, the lower surface of the anti-slip pad is provided with anti-slip grooves.

[0013] As another improvement of this utility model, both the upper and lower shells are made of steel plates.

[0014] The beneficial effects of this utility model are:

[0015] 1.
