Description

Technical Field

[0001] This utility model relates to the field of modular construction technology for marine platforms, specifically to a torch arm installation support device. Background Technology

[0002] In the modular construction of offshore platforms, as the scale of the modules gradually increases, the required size of the flare arms also increases. In previous flare arm construction, the tie rods were typically positioned after the bottom chord was in place, and the upper main chord was installed last. However, the tie rod interfaces of the flare arm have three directions of positioning, making positioning difficult and requiring readjustment when installing the main chord. Although some flare arm construction now uses support fixtures to position and install the main chord first, these fixtures are highly specialized, consume a large amount of materials, and require cutting and scrapping upon removal. These methods result in long construction periods, material waste, and installation difficulties. Utility Model Content

[0026] Example 1

[0027] A torch arm mounting support device, such as Figure 1-7 As shown, it includes several supporting devices that cooperate with each other. The supporting devices include a base 1, a support column 2, a crossbeam 10, a movable seat 16, a rotating seat 17, and a counterweight 7. The support column 2 is fixedly connected to the middle of the top of the base 1 along the longitudinal direction. The crossbeam 10 is rotatably connected to the top of the support column 2. The crossbeam 10 has a through straight groove 101 on the side away from the support column 2.

[0028] The straight through groove 101 is connected to a movable seat 16 via a moving mechanism. The top of the movable seat 16 is connected to a rotating seat 17 via a rotating mechanism. The top of the rotating seat 17 is provided with an arc-shaped groove (e.g., Figure 3 , 7 As shown), the arc-shaped groove is used in conjunction with the bottom chord post 29, and the counterweight 7 is located on one side of the base 1. The counterweight 7 is connected by a connecting rod (such as...). Figure 1 , 2 As shown in the figure (not marked), the counterweight 7 is fixedly connected to the end of the crossbeam 10 away from the straight through groove 101, and the counterweight 7 is rotatably connected to the base 1 around the axis of the support column 2.

[0029] Based on the above structural details, the support device adjusts the position of the rotating seat 17 in three ways, including:

[0030] A. The rotating seat 17 moves along the straight through groove 101 under the drive of the moving mechanism;

[0031] B. The rotating seat 17 rotates around the axis of the support column 2 under the drive of the crossbeam 10;

[0032] C. The rotating seat 17 rotates at the top of the moving seat 16 under the drive of the rotating mechanism; several supporting devices achieve support and position adjustment of the bottom chord column 29 through the coordinated adjustment of the position of the rotating seat, such as... Figure 7 As shown.

[0033] In this embodiment, adjusting the position of the rotating seat means adapting it to the position of the bottom chord column to achieve a supporting effect. This utility model, through three forms of rotating seat position adjustment, can achieve full position coverage of the rotating seat within the rotation range of the straight through groove on the outer periphery of the support column. It is not only suitable for the positioning and installation of the bottom chord column of the torch arm, but also for other types of installation occasions that require repeated position adjustments. When in use, it is not necessary to precisely position the support column, which greatly reduces the difficulty of positioning and adjusting the required installation device, thereby improving construction efficiency, reducing construction costs, and avoiding material waste.

[0034] Example 2

[0035] like Figure 1-4 As shown, the base 1 has a disc-shaped structure. A first annular guide rail 3 is coaxially provided on the upper surface of the base 1. A first annular slider 4 is slidably connected on the first annular guide rail 3. The counterweight 7 is fixedly provided on the top of the first annular slider 4. The top of the counterweight 7 is fixedly connected to the end of the crossbeam 10 through a vertically arranged connecting rod. A connecting plate 8 is fixedly provided on the outer side of the counterweight 7. The connecting plate 8 is fixedly connected to the base 1 through positioning bolts 9.

[0036] This invention effectively improves the support effect of the crossbeam by setting a counterweight, and the counterweight can drive the crossbeam to rotate, ensuring good support while flexibly adjusting the position of the bottom chord column. The function of the positioning bolt 9 is to fix the rotation angle of the crossbeam.

[0037] Example 3

[0038] like Figure 1 , 4 As shown, an annular positioning area 5 is coaxially provided on the upper surface of the base 1 on the outer side of the first annular guide rail 3. The annular positioning area 5 has a plurality of positioning holes 22 evenly distributed around the axis. The positioning bolt 9 is used in conjunction with the positioning holes 22. A scale line 23 for marking the rotation angle of the crossbeam is provided on the upper surface of the base 1 on the outer side of the annular positioning area 5.

[0039] When using it, you can first draw an installation drawing, draw the placement position of the support column on the installation drawing, then mark the required rotation angle of the crossbeam, then mark the position of the rotating seat on the straight through groove, and the rotation angle of the rotating seat itself. This realizes the positioning of the arc groove at the top of one rotating seat. After positioning the arc grooves of multiple support devices, the positioning of the support system when supporting the bottom chord column is realized.

[0040] Example 4

[0041] like Figure 1 , 2 As shown in Figure 3, several stiffening plates (not marked in the figure, intended to improve the stability of the support column) are evenly distributed around the axis of the support column 2 between the lower outer surface of the support column 2 and the upper surface of the base 1. The top of the support column 2 is connected to a fixed seat 12 via a thrust bearing 13. The bottom end of the crossbeam 10 is fixedly connected to the fixed seat 12. A second annular guide rail 19 is coaxially fixed on the outer wall of the support column 10 below the thrust bearing 13. A second annular slider 14 is slidably connected to the second annular guide rail 19. Several diagonal braces 15 are evenly distributed around the axis of the support column 2 between the second annular slider 14 and the bottom end of the fixed seat 12.

[0042] Example 5

[0043] like Figure 1-6 As shown, a first lead screw (not marked in the figure) and a second lead screw 25 are arranged side by side in the linear through groove 101. The moving mechanism includes a sliding block 28 that is slidably connected to the linear through groove 101 and screwed to the first lead screw and the second lead screw 25 respectively. The two ends of the first lead screw and the second lead screw 25 are rotatably connected to the two ends of the linear through groove 101 respectively. The end of the first lead screw passes through the end of the linear through groove 101 and is fixedly connected to the output shaft of the first servo motor 11 preset at one end of the crossbeam. One end of the first lead screw is provided with an active tooth. The wheel 26 and the second lead screw 25 are provided with a driven gear 27 at one end. The driving gear 26 and the driven gear 27 are meshed and connected. The top of the sliding block 28 is fixedly provided with a movable seat 16. The bottom end of the movable seat 16 is slidably connected to the upper end of the crossbeam 10. The middle part of the movable seat 16 is provided with a shaft hole 24 that passes through the sliding block 28. The middle part of the bottom end of the rotating seat 17 is fixedly connected to the output shaft of the second servo motor 18 preset at the bottom of the sliding block 28 through a rotating shaft passing through the shaft hole 24. The second servo motor constitutes a rotating mechanism.

[0044] like Figure 3 , 4 As shown, mounting plates 20 are fixedly installed at the ends of the rotating seats 17 where the arc groove is located. Cameras 21 are respectively installed on the upper surface of the mounting plates 20. The first servo motor 11 and the second servo motor 18 are electrically connected to the power supply through wires and control panel (not shown in the figure). The camera 21 is connected to the display screen and the power supply through wires. The control panel and the display screen are fixedly connected to the lower part of the outer surface of the support column 2.

[0045] In this embodiment, the rotation of the first servo motor drives the sliding block to move back and forth, which in turn drives the rotating seat to move back and forth along the straight through groove, thereby adjusting the position of the rotating seat. The second servo motor drives the rotating seat to rotate, further adjusting its position. The camera is used to collect visual information when the bottom chord column is supported in the arc-shaped groove. The operator can control the rotation angle of the rotating seat based on the visual information to ensure smooth support of the bottom chord column.

[0046] Example 6

[0047] The actual operation of the torch arm installation support equipment is as follows: Figure 1-7 As shown, the process is as follows:

[0048] According to the installation drawings, place multiple support devices in the designated construction positions, such as... Figure 7 As shown; the torch arm is lifted by a crane, and the bottom chord of the torch arm is mounted on the arc-shaped grooves of multiple support devices, as shown. Figure 7 As shown; when it is necessary to adjust the position of the bottom chord column 29, adjust the position of the rotating seat 17 of each support device according to the position to be adjusted, so that the multiple rotating seats 17 can re-support the bottom chord column 29.

[0049] The installation drawing includes: drawing the placement position of the support column 2 on the installation drawing, marking the required rotation angle of the crossbeam 10, marking the position of the rotating seat 17 on the straight through groove 101, and the rotation angle of the rotating seat 17 itself, thus realizing the positioning of the arc groove at the top of one rotating seat 17. After positioning the arc grooves of multiple support devices, the positioning of the support system when supporting the bottom chord column 29 is realized.

[0050] When making adjustments within the operation content, the following adjustment methods are included:

[0051] Adjustment method 1: Push the counterweight 7 to drive the first annular slider to rotate around the support column 2, so that the crossbeam 10 rotates through a set angle, and then fix the first annular slider 4 by the positioning bolt 9 to realize the first adjustment of the position of the rotating seat 17;

[0052] Adjustment method 2: The rotating seat 17 is moved along the straight through groove 101 to a set position by the moving mechanism to realize the second adjustment of the position of the rotating seat 17;

[0053] Adjustment method 3: The rotating seat 17 is rotated by a set angle through the rotating mechanism to achieve the third adjustment of the position of the rotating seat 17.

[0054] Depending on the required adjustment position, one or more combinations of adjustment methods 1-3 can be implemented. For example, adjustment method 1, 2, or 3 can be implemented alone, or adjustment methods 2 and 3, 1 and 2, 1 and 3, or 1 and 2 and 3 can be implemented in combination. After the position of the rotating seat 17 is adjusted, the arc-shaped grooves of each support device face the same direction and reconstruct the support structure of the bottom chord column 29. Figure 7 As shown.

[0055] It should be noted that when the position of the rotating seat needs to be readjusted, the torch arm can be temporarily lifted to separate the bottom chord column from the arc surface before the position can be adjusted.
