TECHNICAL FIELD

[0001] The present application relates to the technical field of generator set installation, in particular to a quick installation box mechanism device for a natural gas differential pressure generator set on an offshore platform. BACKGROUND

[0002] The installation and maintenance space of a conventional natural gas differential pressure generator set used on land is sufficient, and a crane or a forklift can be used for operation during equipment installation, fault maintenance or periodic maintenance, which is convenient and efficient. Therefore, the skid-mounted design of the natural gas differential pressure generator set usually adopts an integrated structure design, which is simple and reliable.

[0003] However, on an offshore platform, the space is limited, the crane is limited in weight, and the installation tools are limited. When the weight of the skid-mounted generator set exceeds the limit of the platform crane, the skid-mounted equipment needs to be disassembled, and the box, prime mover or generator is separately removed and hoisted. After hoisting to the platform, the centering assembly is performed, which is time-consuming and laborious.

[0004] Similarly, the same problem exists in the transportation, hoisting, installation and disassembly process of the natural gas differential pressure generator set, resulting in high installation difficulty and cost. Moreover, the differential pressure generator set is usually installed in a compact production process area on the platform, which is adjacent to the production process facilities. The installation and maintenance operation is not only limited by the overall space size, but also limited by the weight, direction and other factors. Therefore, the traditional skid-mounted structure method cannot be applied, and an innovative split structure needs to be designed. On the one hand, the split structure can be hoisted separately to meet the weight limit of the offshore platform crane. On the other hand, the split structure can be simply and quickly installed and disassembled to meet the operation space size, direction and other limitations of the offshore platform. Therefore, we propose a quick installation box mechanism device for a natural gas differential pressure generator set on an offshore platform. SUMMARY

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] See also Figure 1-6 The present invention provides a technical solution: a quick installation box mechanism device for a natural gas pressure differential generator set on an offshore platform, comprising a box base 1 and a unit base 2, wherein the unit base 2 is installed inside the box base 1, and the width of the unit base 2 is smaller than the width of the inner wall of the box base 1; a double roller assembly 3, which is arranged below the unit base 2 and is used for the installation of the unit base 2 and the box base 1, and comprises a plurality of support members 4 respectively arranged at both sides below the unit base 2, and a plurality of rolling shafts are rotatably connected to the support members 4 5. The rolling shafts 5 are all provided with bearings 6, and are connected to rollers 7 through the bearings 6; the load-bearing components 8 are arranged under the support member 4 and adapted to the box base 1, wherein the box base 1 is fixedly connected with a positioning block 19 installed in conjunction with the unit base 2, and the positioning block 19 is used to limit the final position of the unit base 2 after it is pushed into the box base 1, and the box base 1 is provided with positioning screws 20 for fixing the unit base 2, and the positioning screws 20 are used to fix the two after the position of the unit base 2 is determined.

[0025] Furthermore, the support member 4 includes two groups of mirror-image support side panels 15, and the support side panels 15 are generally right-angled. A positioning sleeve 16 is provided between the two groups of support side panels 15, and a stud bolt 17 is provided in the positioning sleeve 16 to pass through the two groups of support side panels 15. The two ends of the stud bolt 17 are threadedly connected with a fastening nut 18. Among them, according to the length of the existing unit base 2, there are a total of six groups of support members 4, and they are evenly symmetrically arranged under the unit base 2. Without affecting the normal pushing of the unit base 2 into the box base 1, the number of support members 4 is saved. In addition, each group of support members 4 is provided with four rollers 7, and the four groups of rollers 7 are symmetrically arranged in pairs on the two groups of support side panels 15, which can stably move the unit base 2 on the rollers 7 and facilitate the disassembly and maintenance of the two sides.

[0026] like Figure 1 、 Figure 2 、 Figure 5 as well as Figure 6As shown, the load-bearing assembly 8 includes a plurality of jacks 9 respectively arranged under the plurality of support members 4. The outer side of the jack 9 is detachably connected to a mounting ring 10. A telescopic rod 11 is fixedly connected between the corresponding mounting rings 10 on both sides below the unit base 2. A plug-in sleeve 12 is fixedly connected to the mounting ring 10. The plug-in sleeve 12 is provided with a plug-in groove 13, and the plug-in sleeve 12 is arranged vertically to the telescopic rod 11. A plug-in rod 14 is fixedly connected to the mounting ring 10 in the opposite direction of the plug-in sleeve 12. The plug-in rod 14 is adapted to the plug-in groove 13, wherein the end of the plug-in rod 14 away from the mounting ring 10 is set to be conical.

[0027] In a specific embodiment, during installation, the box base 1 is first hoisted to the installation position by using an offshore platform crane, and then multiple sets of jacks 9 are symmetrically placed at the entrance on the side of the box base 1. The jacks 9 on both sides are pulled, and the telescopic rods 11 between the symmetrical mounting rings 10 on both sides cooperate to extend and retract, and are adjusted accordingly according to the width of the unit base 2. The jacks 9 on the same side cooperate with the plug sleeves 12 and the plug rods 14 in opposite directions of the mounting rings 10, and the plug rods 14 are inserted into the plug grooves 13 on the plug sleeves 12. The overall position is adjusted synchronously, which is convenient for operation and saves labor hours. The end of the plug rod 14 is set to a cone shape, which is convenient for manual insertion into the plug groove 13 during docking.

[0028] Put multiple sets of double roller assemblies 3 on the top surface of the jack 9 in turn, and the support 4 contacts the jack 9. By controlling the jack 9 to operate, the double roller assembly 3 is controlled to rise and fall, so that the roller 7 at the top of the support 4 is higher than the installation surface of the box base 1, and then the unit base 2 is hoisted to the side of the box base 1 and above the roller 7. At this time, the male channel steel at the bottom end of the unit base 2 is located between the rollers 7 on both sides of the support 4. Then push the unit base 2 to make it translate on the rollers 7 and gradually move into the inside of the box base 1. When the unit base 2 moves out from the rollers 7 on both sides of the outermost end and contacts the other four sets of rollers 7, the plug sleeve is put into the box base 1. 12 is pulled to remove the plug rod 14 at the opposite direction of the mounting ring 10 from the other set of plug sleeves 12, and carried to the other end of the box base 1, so that the plug sleeve 12 is plugged into the plug rod 14 inside the box base 1. According to the actual distance, this operation is repeated in a cycle until the unit base 2 moves to contact the positioning block 19. At this time, the unit base 2 reaches the installation position and is fixed to the current position in the box base 1 by the positioning screws 20, thereby completing the installation. After that, the double roller assembly 3 and the load-bearing assembly 8 can be removed. When the expander generator on the unit base 2 is maintained later, the above operation is reversed.

[0029] It is worth noting that in order to facilitate the maintenance of the roller 7, the support member 4 is detachable. After unscrewing the fastening nuts 18 at both ends of the stud bolt 17, the stud bolt 17 is pulled out from between the positioning sleeve 16 and the two sets of support side plates 15. The two sets of mirror-image support side plates 15 are separated, and the rolling shaft 5 and the bearing 6 in the roller 7 can be disassembled and maintained. After that, the two sets of rollers 7 on the support side plates 15 can be maintained separately.
