[0002] Steel box girder, also known as steel plate box girder, is a common structural form for long-span bridges. It is generally used on bridges with larger spans. It is called a steel box girder because it looks like a box. Steel box girders have the advantages of light weight, high strength, large span, and convenient construction. Therefore, they are widely used in highway construction. In highway bridge construction, steel box girders are often used as main beams or bridge decks to bear the weight and load of vehicles and pedestrians, which can improve the carrying capacity and safety of highways, and also reduce the cost and time of engineering construction.

[0003] In the prior art, during the installation process, steel box girders are generally processed in sections at a processing plant and then transported to the site. Large machinery is used to stand on the construction site and lift them in sections and blocks.

Two slots 410 are provided on the top of the two fixed boxes 403 near the card slot 409, and one end of a plurality of plug rods 413 is movably embedded in the interior of the plurality of slots 410. The protective plates 411 can be used to protect the equipment inside the two fixed boxes 403 to prevent dust or impurities from adhering to the surface of the PLC controller 414 and the battery 415. By pulling the connecting plate 412 upwards to move the plug rod 413 from the slot 410, and then continuing to pull the connecting plate 412 to slide the protective plate 411 out of the card slot 409, the battery 415 can be charged.

[0044] The method of use and working principle of the present invention are as follows: when in use, a plurality of slings 306 are respectively embedded in the outer surfaces of a plurality of lifting ears 6, and then the fastening bolts 308 are screwed into the mounting holes 307, and pass through the lifting ears 6, and come out from another mounting hole 307, and then the nuts 309 are screwed on to fix them, and the slings 306 and the lifting ears 6 are fixedly installed, so that the lifting device 1 and the steel box girder body 5 are installed together, and the slings 306 and the lifting ears 6 are connected by fastening bolts 308 and nuts 309, which can provide higher connection stability and reduce the risk of shaking and loosening of the steel box girder body 5 during the lifting process. Two front and rear connection points are set in the installation component 3, that is, through two connecting rings 303, the hanging ring 304 and the corresponding wire rope 305 The steel box girder body 5 is hoisted on both sides to improve the hoisting balance, which can better maintain the load balance between the suspension points and reduce the risk of stress concentration. The hoisting device 1 is connected to the external hoisting device, and the hoisting device 1 is lifted by the external hoisting device to drive the two lifting rings 2 to move upward, further drive the movement of the steel box girder body 5, and hoist the steel box girder body 5 to the installation point for installation. The hoisting device 1, the wind speed sensor 402, the warning light 404, the buzzer 405, the power sensor 416, the battery 415 and the PLC controller 414 are electrically connected. The battery 415 can be used to power other devices, and the PLC controller 414 can be used to control the opening and closing of other devices. When hoisting the steel box girder body 5 When the wind speed sensor 402 is started, as the load-bearing block 301 moves, the wind speed sensor 402 can detect the wind speed at the steel box girder body 5. The wind speed sensor 402 usually has a sensitive element, which responds to the air flow and converts the response into an electrical signal and outputs it to the PLC controller 414. The maximum and minimum working thresholds of the wind speed are pre-set inside the PLC controller 414. The PLC controller 414 identifies and compares the received wind speed values. When the wind speed value exceeds the maximum value, the PLC controller 414 controls the buzzer 405 to start and emit a buzzer sound to remind the staff that the wind speed is high and there is a risk of lifting. Measures need to be taken to deal with it, or the lifting work needs to be suspended, so as to achieve wind speed detection. The effect solves the problem that during the hoisting process of the steel box girder, the wind force is mostly sensed manually, but most of the workers are on the ground. The steel box girder gradually rises during the hoisting process. The wind speed on the ground is affected by some obstructions and is different from the wind speed at high altitudes. The wind speed perception is affected, and the wind speed change cannot be responded to in time, which will lead to unexpected situations. The power sensor 416 can detect the power of the battery 415 and transmit the detection result to the PLC controller 414. When the power of the battery 415 is too low, the PLC controller 414 will control the prompt light 404 to flash to remind the workers to charge. The outer surface of the buzzer 405 is provided with a protective shell 406 to protect the buzzer 405.The dustproof hole 407 and the dustproof net 408 can prevent dust from blocking the sound outlet of the buzzer 405 and affecting the use effect of the buzzer 405. The protective plate 411 can protect the equipment inside the two fixed boxes 403 to prevent dust or impurities from adhering to the surface of the PLC controller 414 and the battery 415. By pulling the connecting plate 412 upward, the plug 413 moves from the slot 410, and then continue to pull the connecting plate 412 to make the protective plate 411 slide out of the card slot 409, and the battery 415 can be charged.

[0045] Among them, the lifting equipment 1, wind speed sensor 402, warning light 404, buzzer 405, power sensor 416, battery 415 and PLC controller 414 are all existing technologies, and their components and usage principles are all public technologies, which will not be explained in detail here.
