[0043] The invention will now be further described with reference to the accompanying drawings.

[0044] Example 1: A modular construction system for petrochemical construction, see [link to example]. Figures 1 to 16 It includes vertical members of the transport frame 1, horizontal members of the transport frame 2, right-angle connectors 3, T-shaped connectors 4, rotating auxiliary straight frame 5, horizontal members of the rotating support frame 6, vertical members of the rotating support frame 7, equipment support frame 8, fixing belt 9, arc-bottom connecting frame 10, diameter-changing transition section of the flat-bottom connecting frame 11, and connecting ring of the flat-bottom connecting frame 12.

[0045] The right-angle connector 3 and the T-shaped connector 4 allow the vertical members 1 and horizontal members 2 of the transport frame to be inserted. After insertion, they are connected by bolts to form a base frame for placing the arc-bottomed equipment 13 or the flat-bottomed equipment 14. The right-angle connector 3 is located at the top corner of the base frame, and the T-shaped connector 4 is located in the middle of the base frame. The vertical member 1 of the transport frame, located between the two T-shaped connectors 4, increases the overall structural strength of the base frame.

[0046] The lengths of the vertical members 1 and the horizontal members 2 of the transport frame can be adjusted according to the different equipment to be placed. If the equipment to be placed is long, multiple T-shaped connectors 4 can be set according to the overall length of the equipment and the length of a single horizontal member 2, mainly to enhance the overall stability of the base frame.

[0047] The rotating auxiliary frame 5 is located at one end of the base frame and is also connected to the base frame by bolts. The vertical cross-section of the rotating auxiliary frame 5 is arc-shaped, and the diameter of this arc is affected by the cross-sectional area of ​​the equipment. Therefore, different models of rotating auxiliary frames 5 need to be selected according to different equipment.

[0048] The rotating auxiliary straight frame 5 is provided with a rotating support frame horizontal member 6 and a rotating support frame vertical member 7 at the end away from the base frame. The rotating support frame horizontal member 6, the rotating support frame vertical member 7 and the right-angle connector 3 together form a side support for the bottom of the equipment.

[0049] The equipment support frame 8 has placement openings on both sides of its bottom end for placing the transverse members 2 of the transport frame. After the equipment support frame 8 is placed on the transverse members 2 of the transport frame, the two are connected by bolts, facilitating the installation and disassembly of the equipment support frame 8. The upper surface of the equipment support frame 8 is arc-shaped for placing equipment, and the diameter of this arc is the same as the diameter of the equipment to be placed on the equipment support frame 8.

[0050] After the equipment is placed on the equipment support frame 8, it is secured by the fixing straps 9. The ends of the fixing straps 9 are connected and secured to the ends of the equipment support frame 8 by welding or bolting.

[0051] The arc-bottom connecting frame 10, the flat-bottom connecting frame diameter transition section 11, and the flat-bottom connecting frame connecting ring 12 are bottom support components that support the bottom of the equipment. Different bottom support components are used depending on the type of equipment.

[0052] When the equipment is a curved-bottom device 13, a curved-bottom connecting frame 10 is installed on the rotating auxiliary straight frame 5. The curved-bottom connecting frame 10 includes a connecting rod fixed to the rotating auxiliary straight frame 5 by bolts, and a support plate fixed to the side of the connecting rod 5 away from the rotating auxiliary straight frame 5. A buffer pad is added between the bottom of the curved-bottom device 13 and the equipment support frame 8, and the bottom of the curved-bottom device 13 and the curved-bottom connecting frame 10 are in direct contact after the buffer pad is added. If the bottom of the equipment is a flange structure, the curved-bottom connecting frame 10 can be replaced with a flange face and connected and fixed by bolts.

[0053] When the equipment is a flat-bottomed device 14, a flat-bottomed connecting frame diameter-changing transition section 11 and a flat-bottomed connecting frame connecting ring 12 are installed on the rotating auxiliary straight frame 5. The flat-bottomed connecting frame diameter-changing transition section 11 and the flat-bottomed connecting frame connecting ring 12 are connected and fixed with bolts. The connecting rod of the flat-bottomed connecting frame diameter-changing transition section 11 and the top of the rotating auxiliary straight frame 5 are also connected and fixed with bolts. The flat-bottomed device 14 is placed on the equipment support frame 8, and a buffer pad is added between the bottom of the device 14 and the equipment support frame 8. The bottom of the flat-bottomed device 14 and the flat-bottomed connecting frame connecting ring 12 are connected and fixed with bolts.

[0054] Example 2: A method for using a modular construction system for petrochemical construction, comprising the following steps:

[0055] Step 1: Assembling the base frame. Based on the length of the equipment to be placed, select the appropriate length of the vertical rod 1 and the horizontal rod 2 of the transport frame. Then connect them using right-angle connectors 3 and T-shaped connectors 4, and finally connect them with bolts to complete the abutment assembly.

[0056] Step 2: Installation of the rotating auxiliary frame and side supports. Install the rotating auxiliary frame 5 to one end of the base frame using bolts. Then, connect and install the horizontal members 6 and vertical members 7 of the rotating support frame using right-angle connectors 3. This completes the installation of the side supports, which are then bolted onto the rotating auxiliary frame 5.

[0057] Step 3: Installation of equipment support frames and bottom support components. Based on the overall length of the equipment to be placed, select an appropriate number of equipment support frames 8 and evenly install the equipment support frames 8 onto the bottom frame. Depending on the different equipment being placed (size and center of gravity), select different bottom support components (arc-bottom connecting frame 10 or flat-bottom connecting frame diameter transition section 11 and flat-bottom connecting frame connecting ring 12).

[0058] Step 4: Place the equipment on the equipment support frame 8. Add a buffer pad between the bottom of the equipment and the bottom support. The bottom of the equipment and the bottom support should be in direct contact after the buffer pad is added.

[0059] When the equipment is a rounded-bottom device 13, the bottom support is a rounded-bottom connecting frame 10. If the bottom of the equipment is a flange structure, the rounded-bottom connecting frame 10 can be replaced with a flange face and fixed by bolts.

[0060] When the device is a flat-bottomed device 14, the bottom support consists of a flat-bottomed connecting frame diameter transition section 11 and a flat-bottomed connecting frame connecting ring 12. The bottom of the flat-bottomed device 14 is connected and fixed to the flat-bottomed connecting frame connecting ring 12 using bolts.

[0061] Step 5: Secure the equipment. Use the securing straps 9 to bind and secure the equipment 14. The ends of the securing straps 9 are connected and secured to the ends of the equipment support frame 8, which can be done by welding or bolting.

[0062] Step Six: Equipment Transportation. After the equipment 14 is fixed, it can be transported by loading onto a vehicle or ship. During transportation, the vertical members 1 and the horizontal members 2 of the transport frame will be in direct contact with the vehicle or ship and can be welded and fixed.

[0063] Step 7: Actual installation of the equipment. After the equipment is transported to the installation site, the lifting equipment hoists the top of the equipment. The equipment, together with the integrated device, rotates around the rotating auxiliary frame 5. After the equipment is erected, the modular construction system is dismantled, completing the transportation and straightening work of the equipment.
