Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe construction, in particular to a rotatable steel pipe connector. Background Art

[0002] Steel pipe is a steel material with a hollow cross-section and its length is much larger than its diameter or circumference. It is divided into round, square, rectangular and special-shaped steel pipes according to the cross-sectional shape. It is divided into carbon structural steel pipe, low alloy structural steel pipe, alloy steel pipe and composite steel pipe according to the material. It is divided into steel pipe for transportation pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc. according to the purpose.

[0003] Combining existing technologies, we found that:

[0004] During the construction of steel pipes on site, when vertical or diagonal steel pipes need to be removed or installed, the construction site is often unable to safely remove or install the steel pipes due to the limitation of the lifting angle. The conventional practice is to first cut off the steel pipe and leave one end partially connected, lift the steel pipe to keep it horizontal, and then cut off the other end. This method cannot guarantee that the retained part of the steel pipe will not break during the lifting process. The breaking force of the steel pipe when it breaks poses a risk of mechanical injury, and there is also a risk of damage to the lifting machinery. Therefore, the conventional method has a lot of room for improvement in terms of safety. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes a rotatable steel pipe connector, which forms a rotatable system through the cooperation between multiple semi-ring plates, ear plates, upper rotating arms, lower rotating arms and pin shafts. By installing them respectively at the ends of two steel pipe bodies close to each other, the steel pipe bodies can be cut and welded to ensure construction safety.

[0006] The technical solution to achieve the purpose of the utility model is: a rotatable steel pipe connector, comprising two steel pipe bodies, two semi-ring plates are symmetrically arranged on the outer side of one end of the two steel pipe bodies close to each other, and the adjacent two semi-ring plates are fixed by multiple sets of bolts and nuts respectively, and also includes: a rotating assembly and an adjusting assembly, the rotating assembly is arranged on one side of two of the semi-ring plates; the adjusting assembly is arranged on the inner side of the other two semi-ring plates; the rotating assembly includes multiple groups of ear plates fixed on the outer side of two of the semi-ring plates, and pins arranged at one position of two of the semi-ring plates, the inner sides of the multiple groups of ear plates are rotatably connected to the upper rotating arm and the lower rotating arm, and the other ends of the multiple upper rotating arms and the lower rotating arms are rotatably connected to the outer side of the pin.

[0007] In some embodiments, the adjustment assembly includes a sleeve fixed to the outer side of the other two semi-ring plates, the inner sides of the two sleeves are rotatably connected to screws, the outer sides of the two screws are rotatably connected to moving rods through threads, the two moving rods are respectively slidably connected to one end of the two sleeves, and the two moving rods are slidably connected to the inner sides of the other two semi-ring plates, and one end of the two moving rods is fixed with an abutment plate.

[0008] In some embodiments, a handle is fixed to one end of each of the two screws.

[0009] In some embodiments, the two abutting plates are specifically arranged in an arc shape.

[0010] In some embodiments, one side of the two abutting plates is provided with anti-slip grooves.

[0011] In some embodiments, the plurality of semi-ring plates are made of stainless steel.

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0013] Firstly, the utility model forms a rotatable system through the cooperation between multiple half-ring plates, ear plates, upper rotating arms, lower rotating arms and pins. By installing them respectively at the ends of two steel pipe bodies close to each other, and then cutting and welding the steel pipe bodies, the construction safety is guaranteed;

[0014] Secondly, the present invention rotates two screws separately, and the rotation of the screws drives the moving rod to move through the thread engagement, thereby controlling the movement of the two abutment plates. The positions of the two abutment plates can be adjusted, and ultimately the plates can be adapted to steel pipe bodies of different sizes and diameters to ensure installation.
