The labor intensity of the operators and the construction cost are relatively high, and the construction efficiency is low.

[0004] Therefore, there is an urgent need to design a quick assembly auxiliary device for pump protection pipes of an offshore oil platform to solve the problems of pump protection pipe assembly and welding mentioned above. Content of the Utility Model

Obviously, the described embodiments are some but not all of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0024] Those skilled in the art can understand that although some embodiments herein include certain features included in other embodiments rather than other features, the combination of the features of different embodiments means within the scope of the present utility model and forms different embodiments. For example, in the claims, any one of the claimed embodiments can be used in any combination.

[0025] Next, refer to the attached Figure 1 to the attached Figure 2 Describe the quick assembly auxiliary device for the pump protection pipe of the offshore oil platform of the present utility model.

[0026] As Figure 1 shown, the quick assembly auxiliary device for the pump protection pipe of the offshore oil platform in the present utility model is composed of three identical clamping units. The clamping unit includes an I-beam base 4 and a leveling base 5. The leveling base 5 abuts against the I-beam base 4. An adjusting bolt is screwed on the leveling base 5, and the end of the adjusting bolt screwed with the leveling base 5 abuts against the I-beam base 4. Square steel is provided on the leveling base 5, and the height of the square steel is adjusted by the connected fastening bolt 12. A jack 6 is connected to the square steel, and one end of the jack 6 away from the square steel is connected to a guide plate 7. The guide plate 7 abuts against the butting interface of the adjacent pump protection pipe in the vertical direction so that the pump protection pipes can be welded after assembly. By fixing the three clamping units on the surrounding deck of the pump protection pipe at one time, it can be flexibly adjusted according to the different heights of the butting interfaces, and the resultant force of the three jacks 6 towards the central position is used to position the protection pipe. This application eliminates the need to weld guide plates for each butting interface, greatly reduces the number of welding and grinding operations, saves construction materials, reduces the labor intensity of the operators and the construction cost, and improves the construction efficiency.

[0027] Furthermore, asFigure 1 and Figure 2 As shown in Figure 2 , the adjusting bolts include an upper adjusting bolt 8 and a lower adjusting bolt 9. Both the upper adjusting bolt 8 and the lower adjusting bolt 9 are screwed onto the leveling base 5. The ends of the upper adjusting bolt 8 and the lower adjusting bolt 9 that are screwed onto the leveling base 5 abut against the upper wing plate of the I-beam base 4. The leveling base 5 includes a main board 51 and auxiliary boards 52. The auxiliary boards 52 are symmetrically arranged at both ends of the main board 51. The auxiliary boards 52 at both ends of the main board 51 are respectively clamped onto the I-beam base 4. Upper adjusting bolts 8 are respectively screwed at the four corners of the main board 51, and the multiple upper adjusting bolts 8 respectively abut against the upper surface of the upper wing plate along the vertical direction.

[0028] In this embodiment, preferably, the present application is composed of three identical clamping units, namely a first clamping unit 1, a second clamping unit 2, and a third clamping unit 3. The included angles between the clamping units are all 120 degrees. After the pump protection pipe is hoisted to a certain height, the three clamping units use the resultant force in the central direction by the jacks 6 to quickly position the pump protection pipe.

[0029] Preferably, the positions of the upper adjusting bolt 8 and the lower adjusting bolt 9 correspond. The I-beam base 4 is welded on the deck. Since the flatness of the deck is not uniform, by turning the upper adjusting bolt 8 and the lower adjusting bolt 9, the upper adjusting bolt 8 and the lower adjusting bolt 9 are made to abut against the upper wing plate of the I-beam base 4, thereby making the leveling base 5 horizontal.

[0030] The auxiliary boards 52 are respectively welded at both ends of the main board 51. Preferably, the leveling base 5 is integrally in a C shape, which is convenient for the leveling base 5 to be clamped onto the upper wing plate of the I-beam base 4. Upper adjusting bolts 8 are respectively screwed at the four corners of the main board 51. The four upper adjusting bolts 8 are respectively screwed along the vertical direction into the screw holes of the main board 51. One end of the four upper adjusting bolts 8 abuts against the upper surface of the upper wing plate. By adjusting the screwed lengths of the four upper adjusting bolts 8, the levelness of the leveling base 5 is adjusted.

[0031] Furthermore, as Figure 1 shown, a plurality of lower adjusting bolts 9 are respectively screwed onto the auxiliary boards 52 at both ends, and the plurality of lower adjusting bolts 9 respectively abut against the lower surface of the upper wing plate along the vertical direction. The square steel includes a first square steel 10 and a second square steel 11. The second square steel 11 is vertically arranged on the main board 5 of the leveling base 5. The first square steel 10 is slidably arranged inside the second square steel 11. A jack 6 is connected to the first square steel 10 to clamp the butting joint of adjacent pump protection pipes. The jack 6 is fixedly connected to one side of the first square steel 10, and a guide plate 7 is connected to the end of the jack 6 away from the first square steel 10.

[0032] In this embodiment, preferably, two lower adjusting bolts 9 are respectively screwed on the auxiliary plates 52 at both ends. The four lower adjusting bolts 9 correspond to the positions of the four upper adjusting bolts 8. One screwed end of the four lower adjusting bolts 9 abuts against the lower surface of the upper wing plate. By adjusting the screwed length of the four lower adjusting bolts 9, the levelness of the leveling base 5 is adjusted.

[0033] The first square steel 10 is slidably arranged in the second square steel 11. Preferably, the thicknesses of the first square steel 10 and the second square steel 11 are not less than 4 mm to ensure sufficient strength. The second square steel 11 is vertically welded at the central position of the leveling base 2. The extending end of the first square steel 10 is connected with a jack 6. The jack 6 is fixedly connected to one side of the first square steel 10 to clamp the butting joint of the adjacent pump protection pipes, thereby realizing butt welding.

[0034] Further, as Figure 1 shown, the guide plate 7 includes a vertical section 71 and an inclined section 72. The inclined section 72 is connected to the vertical section 71. The pump protection pipe moves along the inclined section 72 to the vertical section 71 to clamp the butting joint of the adjacent pump protection pipes. A plurality of screwed holes are correspondingly formed in the first square steel 10 and the second square steel 11, and fastening bolts 12 are screwed in the screwed holes to adjust the extending length of the first square steel 10. The second square steel 11 is vertically welded at the central position of the main board 51.

[0035] In this embodiment, the verticality of the guide plate 7 is adjusted by the leveling base 5, the upper adjusting bolts 8 and the lower adjusting bolts 9. Preferably, the guide plate 7 is formed by connecting the vertical section 71 and the inclined section 72. The inclined section 72 is connected to the upper end of the vertical section 71. The pump protection pipe is guided along the inclined section 72 to the vertical section 71 for clamping.

[0036] Preferably, a plurality of screwed holes are correspondingly formed on one side of the first square steel 10 and the second square steel 11, and two fastening bolts 12 are screwed in the screwed holes. The diameter of the fastening bolts 12 is not less than 12 mm to ensure sufficient strength, and then the extending length of the first square steel 10 extending out of the second square steel 11 is adjusted.

[0037] The working principle of the quick butt-welding auxiliary device for the pump protection pipes of the offshore oil platform in the present utility model is as follows:

[0038] First, the leveling base 5 is clamped on the upper wing plate of the I-beam base 4, and the upper adjusting bolts 8 are screwed on the main board 51 of the leveling base 5, and the lower adjusting bolts 9 are screwed on the auxiliary plates 52 of the leveling base 5 to fix the leveling base 5.

[0039] Then, the screwed lengths of the upper adjusting bolts 8 and the lower adjusting bolts 9 are adjusted to make the leveling base 5 horizontal, and the verticality 71 of the guide plate 7 is adjusted. The extending position of the first square steel 10 is adjusted to make the height of the guide plate 7 consistent with the butting joint of the pump protection pipes.

[0040] Finally, the jack 6 of three identical clamping units clamps the docking port of the first pump protection pipe. The second pump protection pipe is guided along the inclined section 72 of the guide plate 7 to the vertical section 71, so that the docking port of the first pump protection pipe is docked with the docking port of the second pump protection pipe. After the assembly is completed, the docking ports of the pump protection pipes are welded.

[0041] Based on the rapid assembly auxiliary device for pump protection pipes on offshore oil platforms, the utility model is fixedly arranged on the surrounding deck of the pump protection pipe at one time through three clamping units, can be flexibly adjusted according to the different heights of the docking ports, and positions the protection pipe by the resultant force of the three jacks 6 towards the central position. This application eliminates the need to weld guide plates for each docking port, greatly reduces the number of welding and grinding operations, saves construction materials, reduces the labor intensity of operators and construction costs, and improves construction efficiency.

[0042] Obviously, the above-mentioned embodiments of the utility model are only examples for clearly illustrating the utility model, rather than limitations on the implementation manners of the utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here.
