The hoisting component 9 includes a mounting frame 91, a fastening nut 92, a limiting frame 93, a limiting slot 94 and a fastening stud 95. The mounting frame 91 is fixedly installed on the bottom end face of the first lifting chain 8. A limiting frame 93 is inserted and installed on the bottom end face of the mounting frame 91. Fastening nuts 92 are arranged on both sides of the end face of the mounting frame 91. A fastening stud 95 is arranged on the top end face of the limiting frame 93, and the top end of the fastening stud 95 passes through the mounting frame 91 and is threadedly connected to the fastening nut 92, which is convenient for fixing the position of the mounting frame 91. A limiting slot 94 is arranged inside the limiting frame 93, which can facilitate the hoisting of both ends of the steel structure. Second lifting chains 10 are fixedly installed on both sides of the bottom end face of the vertical beam frame 7. A positioning component 11 is arranged at the bottom of the second lifting chain 10. The positioning component 11 includes a positioning seat 111, a sleeve 112, a telescopic rod 113, a positioning card plate 114, a fitting wall plate 115 and a mounting positioning hole 116. The positioning seat 111 is fixedly installed on the bottom end face of the second lifting chain 10. A sleeve 112 is fixedly installed inside the positioning seat 111. A telescopic rod 113 is inserted and installed at one end of the sleeve 112. Fastening pins are threadedly connected and installed on both sides of the end face of the sleeve 112, and the fastening pins pass through the sleeve 112 and are fixedly connected to the outer wall of the telescopic rod 113 inside the sleeve 112, which is convenient for fixing the position of the telescopic rod 113. A positioning card plate 114 is welded and installed at one end face of the telescopic rod 113. Fitting wall plates 115 are welded and installed on the top and bottom end faces of the positioning card plate 114, and two mounting positioning holes 116 are opened on the end face of the fitting wall plate 115.

[0022] Working principle of the present invention: When in use, the cross beam frame 6 and the vertical beam frame 7 are installed and fixed through the connecting component 5. The cross beam frame 6 is fixedly installed in the cross beam slot 53 of the hoisting base 51, so that the cross beam frame 6 can have a stable supporting effect on the hoisting component 9 at the bottom of the first hoisting chain 8. The vertical beam frame 7 is fixedly installed in the vertical beam slot 52 of the hoisting base 51, so that the vertical beam frame 7 can have a stable supporting effect on the positioning component 11 at the bottom of the second hoisting chain 10. The first hoisting chain 8 and the hoisting component 9 on one side of the bottom of the cross beam frame 6 are installed at one end of the steel structure. One end of the steel structure is placed in the limit card slot 94 of the limit frame 93. Then, after inserting the fastening stud 95 at the top of the limit frame 93 into the interior of the mounting frame 91, it is threadedly fixed with the fastening nut 92 through the fastening stud 95. Then, the other end of the steel structure is fixed in the same way through the first hoisting chain 8 and the hoisting component 9 on the other side of the bottom of the cross beam frame 6. After the two ends of the steel structure are fixed, the second hoisting chain 10 and the positioning component 11 at the bottom of the vertical beam frame 7 are used to connect the central position of the steel structure. The length of the telescopic rod 113 in the sleeve 112 is adjusted, and the length of the telescopic rod 113 is fixed using a fastening pin, so that the sleeve 112 on one side of the telescopic rod 113 drives the positioning seat 111 and the second hoisting chain 10 to move until the positioning card plate 114 fits against the surface of the steel structure. At this time, the second hoisting chain 10 can be in a taut state. The steel structure is clamped and installed in the center of the positioning card plate 114 through the two positioning card plates 114. Bolts of a suitable specification are used to pass through the installation positioning holes 116 on the fitting wall plate 115, so as to fixedly install the steel structure in the center of the positioning card plate 114. After the fixation is completed, the hook of the crane is clamped with the lifting plate 2 at the top of the lifting ring 1, so that the lifting ring 1 and the lifting plate 2 can be lifted. When the lifting ring 1 and the lifting plate 2 are subjected to tension, the cross beam frame 6 and the vertical beam frame 7 can be hoisted through the load-bearing chain 3 and the connecting component 5, and then the steel structure is hoisted. During the hoisting process, the anti-winding strut 4 can prevent the load-bearing chain 3 from winding. Moreover, since the central position of the steel structure is fixed by the second hoisting chain 10 and the positioning component 11, the steel structure can be effectively prevented from shaking, improving the stability during hoisting the steel structure and making the use safer.
