[0034] The present invention will be further described below with reference to specific embodiments and accompanying drawings. More details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can make similar extensions and derivations based on actual application situations without departing from the spirit of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0035] It should be noted that these and other accompanying drawings are merely examples and are not drawn to scale, and should not be used as a limitation on the scope of protection of this utility model.

[0036] Large components commonly found in the nuclear industry, such as elbows, can weigh up to tons and are also quite large, posing numerous inconveniences when assembling with flanges. For example, with large-diameter pipe elbows, during the long assembly and rotation process with flanges, the flange or elbow may become misaligned, affecting the alignment and requiring constant position adjustments, which impacts the quality of the mating and consumes considerable manpower and resources. Furthermore, the short length of the flange itself poses a safety risk of it falling off.

[0037] The flange assembly device described in this disclosure is used to solve the problem of inconvenience in assembling large mating parts with flanges, so as to complete the assembly process efficiently, improve assembly efficiency and quality, reduce small assembly errors, and save manpower and material resources.

[0038] like Figure 1 As shown, the flange assembly device is used to assemble the mating parts and the flange, where the mass and / or volume of the mating parts 1 is much larger than that of the flange 2.

[0039] The elbow flange assembling device comprises a butt joint piece bearing frame 10 and a flange bearing frame 20. The butt joint piece bearing frame 10 is used for bearing the butt joint piece 1, and comprises one or more butt joint piece adjusting bolts 11, the tail end of the butt joint piece adjusting bolt 11 abutting against the butt joint piece 1, so as to adjust the posture of the butt joint piece 1. The "posture" here includes but is not limited to the concentricity, perpendicularity and three-dimensional orientation and the like.

[0040] The flange bearing frame 20 is opposite to the butt joint piece bearing frame 10, and is used for bearing the flange 2, and comprises one or more flange adjusting bolts 22, the tail end of the flange adjusting bolt 22 abutting against the flange 2, so as to adjust the posture of the flange.

[0041] The flange bearing frame 20 and the butt joint piece bearing frame 10 are two independent bodies, and the relative spacing therebetween can also adjust the assembling gap of the butt joint piece 1 and the flange 2 by adjusting the position of the flange bearing frame 20 or the butt joint piece bearing frame 10.

[0042] In some embodiments, the butt joint piece bearing frame 10 and the flange bearing frame 20 are respectively formed by steel welding, so that some simple profiles such as channel steel, square steel and the like which are common in engineering sites are spliced and then fixed, and have high economy. Preferably, the channel steel and the square steel support are welded perpendicularly to each other, so as to ensure that the butt joint can be placed perpendicularly to the horizontal plane. The nut 30 is fixedly arranged on the butt joint piece bearing frame 10 and the flange bearing frame 20, and the butt joint piece adjusting bolt 11 and the flange adjusting bolt 22 are fixedly arranged on the butt joint piece bearing frame 10 and the flange bearing frame 20 through the nut.

[0043] The outer shape of the butt joint piece bearing frame 10 and the flange bearing frame 20 is adapted to the outer shape of the butt joint piece and the flange. In Figure 1 and Figure 2 In the embodiment shown in the drawings, the butt joint piece 1 is an elbow, the elbow comprises a butt joint end 101, a non-butt joint end 102 and an elbow pipe 103 connecting the butt joint end 101 and the non-butt joint end 102, and the butt joint piece bearing frame 10 is configured by a steel pipe to accommodate the space 18 of the elbow pipe 103, and further comprises a cross bar 19 for bearing the butt joint end 101 which has a lower position. Relatively, the structure of the flange bearing frame 20 is simpler, and comprises a cross bar and a fence 25 for bearing the flange.

[0044] In this way, the butt joint piece carrier 10 and the flange carrier 20 are used to carry the butt joint piece 1 and the flange 2 respectively, and the butt joint piece adjusting bolt 11 and the flange adjusting bolt 22 are used to adjust the positions of the butt joint piece 1 and the flange 2. For example, the butt joint piece adjusting bolts 11 arranged on both sides, the bottom and the back of the butt joint piece carrier 10 are used to fix butt joint pieces 1 of different thicknesses, the butt joint piece adjusting bolts arranged at the back are used to fine-tune the perpendicularity of the butt joint piece 1, and the butt joint piece adjusting bolts arranged at the bottom are used to adjust the height of the elbow. For another example, the flange adjusting bolts 22 arranged at the bottom and both sides of the flange carrier 20 are used to fix flanges of different diameters, and the flange adjusting bolts arranged at the bottom are used to adjust the height of the flange.

[0045] Preferably, to avoid damaging the butt joint piece and the flange, the tail ends of the butt joint piece adjusting bolt and the flange adjusting bolt are arc-shaped 24, and a protective rubber sleeve can also be arranged to avoid damaging the steel surface of the flange during transportation and assembly.

[0046] The flange assembly device also comprises a centering control assembly, which comprises a sensor and a controller. The sensor is arranged at the center of the butt joint piece 1 and is signal-connected with the controller, and is used to detect the center line of the flange 2. The controller is used to calculate and output the compensation amount for aligning the center line of the flange 2 with the center of the butt joint piece 1.

[0047] That is, the sensor is placed at the center line of the side of the butt joint piece 1 facing the flange, such as the end face of the butt joint end of the elbow. The center of the flange is captured by the sensor, and if there is a deviation, the sensor feeds back a signal to the controller to calculate the position compensation amount of the flange. In this way, it is easier to adjust the relatively small flange in terms of quality and size for a large butt joint piece.

[0048] Preferably, on the basis of the above embodiment, the flange carrier also comprises a bolt automatic adjusting member, such as an electric wrench assembly, which is signal-connected with the controller and is used to adjust the extension amount of the flange adjusting bolt to adjust the posture of the flange. The controller transmits the position compensation amount signal of the flange to the bolt automatic adjusting member to automatically adjust the posture of the flange and realize centering.

[0049] The sensor includes but is not limited to a laser sensor or an ultrasonic distance measuring sensor.

[0050] The specific use process of the flange assembly device will be introduced below.

[0051] In use, first, the flange sets the device to the working area of the horizontal surface. Then, the butt joint is placed on the butt joint carrier by lifting or manually, and the levelness and perpendicularity of the elbow are measured by using a level, and the levelness is adjusted by using one or more butt joint adjusting bolts, so that the butt joint is placed horizontally and vertically, and the butt joint adjusting bolt is used to clamp and fix the butt joint, so that the butt joint does not deviate during work. Then, the flange is placed in the flange carrier, and the height of the flange is adjusted by using the flange adjusting bolt below the flange, so that the distance between the flange and the elbow is adjusted, and the gap between the sets is satisfied. Rotate the flange, adjust the flange bolt hole position, put the sensor into the butt joint, and automatically adjust the center line of the flange and the center line of the elbow by using the centering control assembly and the bolt automatic adjusting piece, and then perform the set.

[0052] The flange set device is safe, reliable and easy to operate, and the use of lifting equipment and the help of other personnel during the set are saved, the position of the butt joint and the flange is coarsely adjusted and finely adjusted by using the butt joint adjusting bolt and the flange adjusting bolt, a large amount of manpower and material resources are saved, the installation quality is improved, and the installation efficiency is greatly improved.

[0053] The application uses specific words to describe the embodiments of the application. As "one embodiment", "an embodiment" and / or "some embodiments" means a certain feature, structure or characteristic related to at least one embodiment of the application. Therefore, it should be emphasized and noted that the "an embodiment" or "one embodiment" or "an alternative embodiment" mentioned in different positions in the specification does not necessarily refer to the same embodiment. In addition, some features, structures or characteristics in one or more embodiments of the application can be properly combined.

[0054] Although the utility model discloses the above-mentioned preferable embodiment, it is not used to limit the utility model, and any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the utility model. Therefore, any modification, equivalent change and modification of the above-mentioned embodiment according to the technical essence of the utility model, which does not deviate from the technical scheme of the utility model, falls within the protection scope defined by the claims of the utility model.
