[0031] Reference Figure 1-2 This utility model provides a single-point lifting device with an adjustable center of gravity for hoisting MBR modules, including a main frame 1, a sliding counterweight 2, and an adjustable connecting part 3. The sliding counterweight 2 is movably mounted on the main frame 1, allowing adjustment of the overall center of the lifting device after the MBR module is hoisted. The adjustable connecting part 3 enables the lifting device to connect with the MBR module, allowing the main frame 1 to be connected to external hoisting equipment to achieve the hoisting of the MBR module.
[0032] A lifting point 4 is fixed in the middle of the main frame 1. The lifting point 4 can be connected to the lifting equipment to realize the connection between the lifting device and the lifting equipment. Specifically, the main frame 1 includes two vertical rods 11 and two horizontal rods 12. The two vertical rods 11 are arranged in parallel and are strip-shaped. The two horizontal rods 12 are arranged in parallel at both ends of the vertical rods 11. The two vertical rods 11 are fixed between the two horizontal rods 12, and the vertical rods 11 and the horizontal rods 12 are arranged perpendicularly. The main frame 1 has a simple structure and low manufacturing cost, and can provide stable support for the hoisted MBR module. It should be noted that the main frame 1 can also use other shaped plates to support the MBR module. However, the main frame 1 composed of rods is lightweight and simple, and facilitates the installation of other connection structures inside.
[0033] A support frame 5 is fixed inside the main frame 1, and the lifting point 4 is fixed inside the support frame 5. Specifically, the support frame 5 includes two support rods 51 and a connecting rod 52. The support rods 51 are fixed between two vertical rods 11 and are arranged along the extension direction of the vertical rods 11. The connecting rod 52 is fixed between the two support rods 51, and the lifting point 4 is fixed between the two vertical rods 11. The support frame 5 can improve the strength of the lifting device and can be connected to the lifting point 4.
[0034] The adjustable connecting part 3 is detachably connected to the lower side of the main frame 1. Multiple slide rails 111 are fixed to the lower side of the main frame 1, and multiple sliding counterweights 2 are slidably connected to the slide rails 111. Threaded holes are provided on the side walls of the sliding counterweights 2, and bolts 21 that can tighten against the slide rails 111 are threaded into these holes. In use, the adjustable connecting part 3 can be connected to the MBR module. By disassembling the adjustable connecting part 3, it can be fixed at different positions on the main frame 1, thus adapting to connect with MBR modules of different sizes, demonstrating strong applicability. After the lifting device and MBR module are connected, the lifting device and lifting point 4 are then connected. By moving the sliding counterweights 2, the lifting device is leveled, thereby placing the center of gravity of the lifting device on the lifting point 4, improving the stability and safety of the lifting device.
[0035] As one embodiment, the adjustable connection part 3 includes two mutually perpendicular connecting plates 31. Each connecting plate 31 has a connecting hole 311 on its surface. The MBR lifter can be connected to the connecting hole 311 for lifting. The connection structure between the MBR lifter and the connecting hole 311 is prior art and will not be described further in this application. A mounting plate 32 is fixed to the two connecting plates 31 at the corner of the two connecting plates 31. The mounting plate 32 has a through hole 321 on its surface. The crossbar 12 has multiple mounting holes 121 arranged along the extension direction of the crossbar 12. Threads are formed in the mounting holes 121, and screws 322 that can pass through the through holes 321 are threaded into the mounting holes 121. By removing the screws 322, the position of the adjustable connection part 3 can be adjusted on the crossbar 12, thereby allowing the connection position between the lifter and the MBR module to be adjusted within a certain range according to the size of the MBR module.
[0036] As one embodiment, multiple slide rails 111 are fixed to the lower side of the vertical rod 11. Two slide rails 111 are provided below the vertical rod 11. The extension direction of the slide rails 111 is the same as the extension direction of the vertical rod 11. The slider moves along the extension direction of the vertical rod 11, so that the slider can adjust the horizontal state of the lifting device, so that the lifting device can be set horizontally, and the center of the lifting device is adjusted to be close to the lifting point 4 to keep the lifting device stable.
[0037] As one embodiment, a bubble level 6 is fixed to the upper side of the vertical rod 11 of the main frame 1, which facilitates real-time indication of the horizontal status of the lifting equipment, improving lifting accuracy and safety. The bubble level 6 is prior art, and its specific structure will not be described in detail in this application.
[0038] The implementation principle of this utility model is as follows: During use, the adjustable connecting part 3 can be connected to the MBR module. By disassembling the adjustable connecting part 3, it can be fixed at different positions on the main frame 1, thus adapting to connect with MBR modules of different sizes, making it highly versatile. After the lifting device and the MBR module are connected, the lifting device and the lifting point 4 are then connected. By moving the sliding counterweight 2, the lifting device is leveled, thereby ensuring that the center of gravity of the lifting device is located on the lifting point 4, improving the stability and safety of the lifting device.
