[0043] Slide sleeves 34 are provided on both sides of the bottom of the fixed plate 1, and the two slide sleeves 34 are fixedly connected to the bottom of the two first threaded blocks 3301 and the second threaded block 3302 respectively. The two slide sleeves 34 are slidably connected on both sides of the inside with clamping plates 35, and the two clamping plates 35 are fixedly connected to the opposite ends with racks 36, and the two racks 36 are arranged in opposite directions. The tops of the two slide sleeves 34 are fixedly connected with third motors 37, and the output ends of the two third motors 37 pass through the slide sleeves 34 and are rotatably connected with the slide sleeves 34.

In this way, when the steel structure is hoisted, the steel structure can be directly installed during the hoisting process without manual climbing to a high place for installation, which increases safety and greatly reduces the operation of intermediate installation steps and improves installation efficiency.

[0046] After the steel structure is installed, the clamping plate 35 is loosened from the steel structure to separate the device from the installed steel structure, and the steel structure is hoisted again, so that multiple steel structures are gradually installed.

[0047] When the fourth motor 39 is started to drive the first screw rod 3201 to rotate, the first screw rod 3201 drives the first threaded block 3301 to move, so that the first threaded block 3301 slides inside the slide rail 31, and drives the sliding sleeve 34 to move, or the fourth motor 39 drives the second screw rod 3202 to rotate and drive the second threaded block 3302 to move, and the second threaded block 3302 drives another sliding sleeve 34 to move, which is conducive to moving one sliding sleeve 34 and shortening the distance between the two sliding sleeves 34, so as to adapt to different sizes of steel structures for installation. When one end of the steel structure is installed, the hoisting machine drives the fixed plate 1 to move toward the side where the installation is completed. At the same time, the two fourth motors 39 are started at the same time to drive the first screw rod 3201 and the second screw rod 3202 to rotate synchronously, thereby driving the first threaded block 3301 and the second screw rod 3202 to move, so that the fixed plate 1 and the two sliding sleeves 34 move relative to each other, so that the sliding sleeve 34 drives the steel structure to move to the other end, and then the mounting bolts 6 are installed on the other side of the steel structure, which is conducive to the installation of structures of different lengths.
