[0027] In the implementation of this utility model: the user places materials on the lifting frame 2, and then starts the hoist to lift the materials to a high place. When it is necessary to adjust the height of the materials, the electromagnet 36 is activated, which drives the active block 35 to move away from the bottom shaft 33, thereby causing the two driven blocks 38 to move away from each other, so that the intermediate shaft 31 is located at the lowest point of its movement range. At this time, the middle gear 312 meshes with the bottom gear 331, and the drive component 32 is activated to drive the bottom shaft 33 to rotate, thereby changing the height of the lifting frame 52 and the materials on it. When it is necessary to fix the lifting frame 2, the electromagnet 36 is activated, driving the driving block 35 to move closer to the bottom shaft 33. The rack 37 meshes with the bottom gear 331 to lock the bottom shaft 33. Then the driving block 35 continues to move towards the bottom shaft 33. At this time, the spring is compressed, and the pusher block 352 drives the driven block 38 to move closer to each other. Under the action of the connecting rod 381, the intermediate shaft 31 rises to the highest point of its range of motion. The middle gear 312 meshes with the top gear 341. At this time, the driving component 32 can drive the top shaft 34 to rotate, so that the two threaded blocks 391 on the same side shaft 39 move closer to each other. Under the action of the cross rod group 393, the fixing plate 392 descends and abuts against the top surface of the lifting frame 2 to fix the lifting frame 2. Users can ensure good transmission efficiency by adding transmission gears to the side shaft 39 and top shaft 34 and replacing the belt with a chain. They can also adjust the spring coefficient to reset the device (i.e., when the driven blocks 38 are far apart). The spring can give the rack 37 a large enough thrust to keep the bottom shaft 33 locked, thus achieving the position switching of the intermediate shaft 31 while ensuring the safety of the device.

[0028] This utility model provides a temporary fixing device for high-altitude steel structure hoisting construction, which has the following advantages:

[0029] 1.

[0030] 2. By setting a rack and pinion and a bottom gear, the bottom shaft can be locked while driving the intermediate shaft to rise and fall, thus ensuring that the components will not shake during welding, ensuring good safety, and reducing the risk of personal injury to the user.
