Description

Technical Field

[0001] The present invention relates to the technical field of pipeline prefabrication and processing, and in particular to a high-precision assembly platform device for large pipelines. Background Art

[0002] With the development of the construction industry in China, the construction mode of prefabricated buildings that advocates green and low-carbon is promoted. The prefabricated building field includes the prefabrication and installation of large pipelines in machine rooms. Through BIM information technology modeling, pipeline cutting, assembly, and welding are completed in advance in the factory and transported to the site for flat installation. The construction period is shortened and the efficiency is significantly improved. It not only improves the construction quality, but also has the advantages of low carbon environmental protection, resource conservation, etc., avoiding the generation of a large amount of construction waste and the waste of labor. Compared with on-site construction, for pipeline prefabrication and assembly, all pipeline components are completed in the processing factory in advance and transported to the site, which requires extremely high processing quality and precision of the pipelines.

[0003] However, the precision of pipeline pre-processing is insufficient, which is not conducive to on-site assembly. There are often situations where the error is too large to be installed, and rework is required, affecting the construction progress and wasting manpower and material resources. In addition, when welding and assembling the cylinder body of a large-diameter pipeline with the flange at its end, it is necessary to ensure the coaxiality of the pipeline cylinder body and the flanges at both ends, and the bolt holes on the flanges at both ends also need to be ensured to correspond one by one, with high assembly precision requirements. Currently, before welding a traditional large-diameter pipeline and a flange, manual scribing is usually carried out in advance, and then welding is carried out according to the scribed position. This not only has a relatively high labor cost and low production efficiency, but also easily generates human errors, and the product quality cannot be effectively guaranteed.

[0063] During the assembly process of one end of a 90° elbow and a straight pipe, by controlling the entire angle limiting component 4, the rotation motor operates to drive the driving gear 42 to rotate. Subsequently, the rotation gear 45 conducts the rotation, and then drives the entire movable backing plate 3 to form a 90-degree angle with the fixed backing plate 2. Then, the movable angle plate 64 in the first moving groove 61 of the fixed backing plate 2 is translated and pushed to fit around the A surface of the 90° elbow. Since the movable angle plate 64 forms a 90° angle with the fixed backing plate 2 and also forms a 90° angle with the top surface of the platform body 1, the B surface of the 90° elbow also forms a 90° angle with the movable angle plate +64, the fixed backing plate 2, and the top surface of the platform body 1. Then, place the straight pipe and move it to the B surface of the 90° elbow, and adjust it to the required size using the dimension scale 15. Subsequently, turn on the electromagnetic suction panel 51 to adsorb the straight pipe and the 90° elbow to the inside of the fixed backing plate 2 and the movable backing plate 3, preventing the straight pipe and the 90° elbow from shaking during the spot welding and shaping process, and then complete the spot welding and shaping.

[0064] During the assembly process of both ends of a 45° elbow and a straight pipe with a flange, first adjust the position and lifting height through the second lifting backing plate height component 8. Subsequently, the second lifting backing plate 84 is parallel to the movable backing plate 3, so the second lifting backing plate 84 forms a 90° angle with the fixed backing plate 2. Then, install a flange at the straight pipe end of the 45° elbow and the straight pipe component. Then, turn on the electromagnetic suction panel 51, and at the same time, the clamping component 16 can be used to fix the flange to prevent the flange and the straight pipe from shaking, and then complete the spot welding and shaping.

[0065] During the assembly process of a three-way straight pipe and a branch pipe, first control the entire angle limiting component, start the rotation motor, and drive the movable backing plate 3 to rotate around the output shaft 41 until the angle with the fixed backing plate 2 is 180°. Subsequently, adjust the first lifting backing plate 1 to the required height again, place the straight pipe and the branch pipe. Then, turn on the electromagnetic suction panel 51 again to prevent the straight pipe from shaking and keep the straight pipe parallel to the fixed backing plate 2 and the movable backing plate 3. Since the first lifting backing plate 71 forms a 90° angle with the fixed backing plate and the movable backing plate at this time, the required size and angle of each branch pipe can be adjusted through the first lifting backing plate 71, and then complete the spot welding and shaping.
