Description

Technical Field

[0001] The utility model relates to the technical field of pipeline construction, in particular to a portable pipeline centering connector. Background Art

[0002] In the field of civil engineering pipeline construction, it is often necessary to lay pipelines over a large area. However, in order to ensure that the pipelines are easy to transport and install, the pipelines are divided into different sections and lengths. However, the materials, diameters, etc. of each section of the pipeline may be different.

[0003] When connecting pipelines, not only the connection position should be considered to facilitate construction, but also various issues such as different materials, diameters, thicknesses, etc. The most important thing is that the pipelines should be connected correctly to ensure the use effect.

[0004] Current construction methods:

[0005] ①One worker holds the ends of the two pipes to be connected and aligns them manually, while another worker connects them;

[0006] ② When the pipeline is heavy or cannot be handled by one person, two or more workers will operate the two ends of the pipeline respectively, align them, and then one worker will connect them;

[0007] ③ Place the pipeline on the ground, use stones, sand or wooden wedges to support the low places, and use your feet and body weight to press down the high places to achieve the purpose of alignment;

[0008] ④The connection between pipelines is usually made by welding, heating, sealant, connectors, joint sleeves, etc.

[0009] There are problems with the current construction method:

[0010] ① The workers hold the pipes close to each other, and the alignment accuracy of the pipes is extremely challenging for their personal level, which has a huge impact on the control of construction quality. In addition, the alignment efficiency is not high and deviations are prone to occur;

[0011] ② Multiple people perform alignment operations, which not only wastes labor, but also requires constant adjustment of the alignment positions on both sides, making coordination and operation difficult;

[0012] ③Due to the operations of electric welding, heating and glue injection, workers need to wear protective equipment, which may cause harm to other people around them, thus creating a great safety hazard for the surrounding personnel;

[0013] ④ When pipelines are placed on the ground, high pipelines are prone to be squeezed and cracked or damaged due to uneven weight, and low pipelines are prone to rolling or slipping at the support pad position, which have a serious impact on the alignment and connection of the pipelines;

[0014] ⑤ When the pipeline is not aligned, not only the material consumption increases exponentially, but also during use, the joints are easily damaged because the degree of patency is seriously lower than that of normal pipelines. Utility Model Content

In addition, the present embodiment is easy to operate, greatly reduces the requirements on personnel quality, saves labor, and avoids injuries to construction workers caused by sparks generated during construction.

[0036] Specifically, the outer frame 1 is a square frame, and there are at least two limit openings 11. When there are two limit openings 11, the two limit openings 11 are diagonally arranged, which can effectively align the two outer frames 1 and ensure that they can align the two pipelines 4.
