[0002] The installation and maintenance space of the traditional natural gas differential pressure generator set used on land is sufficient. When installing the equipment, repairing faults or disassembling for regular maintenance, tools such as cranes or forklifts can usually be used for operation, which is convenient and efficient. Therefore, the skid-mounted design of the natural gas differential pressure generator usually adopts an integrated structural design, which is simple and reliable.

[0003] However, due to space constraints, crane weight limits, installation equipment and other conditions on offshore platforms, if the weight of the skid-mounted generator set exceeds the platform crane limit and the entire skid cannot be lifted by the platform crane, the skid-mounted equipment needs to be disassembled, and the box, prime mover or generator needs to be removed and lifted separately, and then aligned and assembled after being lifted to the platform. This process is time-consuming and labor-intensive.

[0004] Similarly, the transportation, hoisting, installation and disassembly of natural gas differential pressure generator sets have the same problems, which makes installation difficult and costly. In addition, differential pressure generators are usually installed in the compact production process area of ​​the platform, close to the production process facilities. Installation and maintenance operations are not only limited by the overall space size, but also by weight, direction, etc. Therefore, the traditional skid-mounted structure is no longer applicable, and it is necessary to design an innovative split structure that can be hoisted separately to meet the weight limit of the offshore platform crane, and on the other hand, can be easily and quickly installed and disassembled to meet the restrictions on the size and direction of the offshore platform operating space. To this end, we propose a quick installation box mechanism device for natural gas differential pressure generator sets on offshore platforms. Summary of the invention

[0024] See also Figure 1-6 The present invention provides a technical solution: a quick installation box mechanism device for a natural gas pressure difference 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 member 4 5, bearings 6 are provided on the rolling shafts 5, and rollers 7 are connected through the bearings 6; load-bearing components 8, which are arranged below the support member 4 and matched with the box base 1, wherein a positioning block 19 installed in cooperation with the unit base 2 is fixedly connected to the box base 1, and the positioning block 19 is used to limit the final position of the unit base 2 after being pushed into the box base 1, and a positioning screw 20 for fixing the unit base 2 is provided on the box base 1, and the positioning screw 20 is 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 support side panels 15 that are mirror-imaged, and the support side panels 15 are in a right-angle shape as a whole. A positioning sleeve 16 is arranged between the two groups of support side panels 15, and a stud bolt 17 that penetrates the two groups of support side panels 15 is arranged in the positioning sleeve 16. Both 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, a total of six groups of support members 4 are arranged, and they are evenly symmetrically arranged below 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, four rollers 7 are arranged on each group of support members 4, and the four groups of rollers 7 are symmetrically arranged on the two groups of support side panels 15 in pairs, so that the unit base 2 can be stably moved on the rollers 7, and it is convenient to disassemble the two sides for maintenance.

[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 groups of support members 4, and a mounting ring 10 is detachably connected to the outer side of the jack 9, and a telescopic rod 11 is fixedly connected between the corresponding mounting rings 10 on both sides below the unit base 2, and a plug-in sleeve 12 is fixedly connected to the mounting ring 10, and a plug-in groove 13 is provided in the plug-in sleeve 12, and the plug-in sleeve 12 is vertically arranged to the telescopic rod 11, and a plug-in rod 14 is fixedly connected to the mounting ring 10 in the opposite direction of the plug-in sleeve 12, and 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 arranged to be conical.

[0027] In a specific implementation, during installation, the box base 1 is first hoisted to the installation position by an offshore platform crane, and then multiple groups of jacks 9 are symmetrically placed at the entrance of the side of the box base 1 in sequence, and 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, and the jacks 9 on the same side cooperate with the plug sleeves 12 and the plug rods 14 in the opposite directions of the mounting rings 10, and the plug rods 14 are inserted into the plug slots 13 on the plug sleeves 12, and the overall position is adjusted synchronously, which is convenient for operation and saves man-hours, and the end of the plug rod 14 is set to a cone, which is convenient for manual insertion into the plug slot 13;

[0028] Put multiple sets of double roller assemblies 3 on the top surface of the jack 9 in sequence, and the support member 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 member 4 is higher than the installation surface of the box base 1. Then, the unit base 2 is hoisted to the side of the box base 1 and is located above the roller 7. At this time, the male channel steel at the bottom of the unit base 2 is located between the rollers 7 on both sides of the support member 4. Then, the unit base 2 is pushed to 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, it contacts the other four sets of rollers 7. At this time, the plug-in sleeve 12 is pulled to move the plug-in rod 14 at the opposite direction of the mounting ring 10 out of the other group of plug-in sleeves 12, and carried to the other end of the box base 1, so that the plug-in sleeve 12 is plugged with the plug-in 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 the unit base 2 is fixed to the current position in the box base 1 by the positioning screws 20, thereby completing the installation, and then 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 have been 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.
