Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, a pipeline welding leveling docking device of the utility model comprises two oppositely arranged docking plates 1, the docking plates 1 are provided with docking holes 101 for sleeved pipes 4, at least three crossbeams 2 are connected between the docking plates 1, the crossbeams 2 are evenly distributed around the periphery of the docking holes 101, the crossbeams 2 are provided with bolt holes 201 at intervals, and bolts 3 cooperating therewith are provided in the bolt holes 201. The bolts 3 corresponding to the bolt holes 201 arranged at intervals on the crossbeams 2 are respectively opposite to the side walls of the docking ends of the two pipes 4 to be welded. The two oppositely arranged docking plates 1 are fixedly connected by the crossbeams 2, and the number of the crossbeams 2 is three or four or more. The shape of the docking plate 1 is cylindrical or square columnar.

[0025] A pipeline welding leveling docking device based on the above structure, a pipeline welding leveling docking device of the present application is used for docking and leveling when the pipeline 4 is welded. When the pipeline welding leveling docking device docks and level the pipeline 4, the docking hole 101 of the docking plate 1 at one end of the pipeline welding leveling docking device is passed through the docking end of a pipeline 4, and the docking plate 1 is sleeved on the docking end of the pipeline 4, and the butt end of another pipeline 4 is passed through the docking hole 101 of the docking plate 1 at the other end of the pipeline welding leveling docking device, so that the two pipelines 4 form a preliminary docking and leveling alignment (alignment), and the two bolts 3 on the crossbeam 2 are respectively opposite to the side walls of the butt ends of the two pipelines 4, and the bolts 3 are tightened so that the bolts 3 are against the side walls of the pipeline 4, and the corresponding bolts 3 are tightened respectively to quickly and accurately level and align the two pipelines 4, so as to ensure that the butt ends of the two pipelines 4 are aligned (aligned) and fixed. After the butt ends of the two pipes 4 are aligned and fixed, the two pipes 4 can be welded by arc welding. After welding is completed, the bolts 3 are reversely loosened, the bolts 3 are separated from the side wall of the pipe 4, and the pipe welding leveling butt device is removed and used for butt, leveling, aligning and fixing of another pipe 4 to be welded. The pipe welding leveling butt device of the present application has a simple structure and is easy to operate. The operator can quickly and accurately butt, level and align the two pipes 4, thereby improving the efficiency and quality of the pipe 4 welding construction and reducing the labor intensity and construction cost. The butt end of the pipe 4 is the welding end of the pipe 4.

[0026] Preferably, four cross beams 2 are connected between the butt joint plates 1 .

[0027] The four cross beams 2 are evenly distributed on the periphery of the docking hole 101 or close to the periphery of the docking hole 101. When the pipeline welding leveling docking device docks and level the pipeline 4, the pipeline 4 is adjusted from four different directions to facilitate rapid leveling.

[0028] Wherein, the butt joint plate 1 is in a cylindrical shape.

[0029] The cylindrical butt joint plate 1 reduces the material and weight of the butt joint plate 1 and is convenient for operators to pick up and install.

[0030] Preferably, the docking plate 1 and the docking hole 101 are coaxial.

[0031] When the pipeline welding leveling docking device docks and level the pipeline 4, the two docking plates 1, the two docking holes 101 and the docking ends of the two pipelines 4 are coaxial, and the stress of the pipeline welding leveling docking device on the pipeline 4 and the reaction force of the pipeline 4 on the pipeline welding leveling docking device are uniform, which is conducive to the leveling and docking of the pipeline 4.

[0032] Preferably, the cross beam 2 is vertically arranged between the docking plates 1 , and the distance between the cross beam 2 and the edge of the docking hole 101 is the same.

[0033] The bolt holes 201 are evenly distributed along the length direction of the crossbeam 2 .

[0034] The bolt holes 201 are evenly distributed along the length direction of the beam 2. The two bolt holes 201 divide the beam 2 into three sections. When the pipeline welding leveling and docking device level and docks the pipeline 4, the stress of the bolts 3 on the pipeline 4 is uniform, which is conducive to the leveling and docking of the pipeline 4.

[0035] As an implementable embodiment, the butt joint plate 1 and the cross beam 2 are both steel structural members, and the butt joint plate 1 and the cross beam 2 are fixedly connected by welding.

[0036] The butt plate 1 and the cross beam 2 made of steel have high strength, high hardness, high toughness, high stability and corrosion resistance.

[0037] The outer walls of the butt joint plate 1 and the cross beam 2 are both provided with a protective layer.

[0038] A protective layer is provided on the outer wall of the butt joint plate 1 and the cross beam 2 to effectively prevent corrosion, thereby increasing the service life of the butt joint plate 1 and the cross beam 2, and thus increasing the service life of the pipeline welding leveling butt joint device. The number of protective layers is at least one layer, such as one layer or two layers or more layers. The protective layer may be a galvanized layer or an anti-corrosion paint layer.

[0039] Preferably, the protective layer is a paint layer.

[0040] The outer walls of the butt joint plate 1 and the cross beam 2 are sprayed with paint to form a paint layer, which reduces oxidation corrosion of the butt joint plate 1 and the cross beam 2. The anti-corrosion method of spraying paint to form a paint layer has low anti-corrosion cost.

[0041] Preferably, the number of the paint layers is two.

[0042] The number of paint layers is two, which provides better protection for the butt joint plate 1 and the cross beam 2 and brings better anti-corrosion effect to the butt joint plate 1 and the cross beam 2.

[0043] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
