[0002] Steel structure joints refer to the key areas that connect various components in steel structures. Steel structures are mainly connected and fixed by bolts to ensure the stability of the entire structure. During use, steel structures or steel structure joints may be damaged or require maintenance. Through installation and disassembly, structural adjustments or replacements can be made more easily to adapt to design changes or different project requirements.

[0003] The common method of loading and unloading bolts of steel structure joints is manual tightening. Manual tightening during installation cannot ensure that each bolt is precisely tightened according to the design requirements, which may lead to uneven connection points or quality problems, affecting the stability of the overall structure. At the same time, the nut must be placed in the threaded opening at the other end of the steel structure joint in advance waiting for the bolt to enter. Manual tightening during disassembly cannot involve the nut at the other end of the steel structure joint, which may cause the nut to rotate with the bolt after the bolt rotates to remove part of the force, making it difficult to loosen the bolt as a whole, increasing the difficulty of disassembly.

At this time, the engaging block 15 is engaged in the engaging groove 16, reducing the volume of the loading and unloading device for easy storage.

[0036] Working principle: When the steel structure joint loading and unloading device is used, the motor 6 drives the gear 7 to mesh with the rack 5 to make the slider 4 slide to the left in the slide groove 3, and then put the screw into the gun head of the bolt gun 1 and align it with the threaded opening at the steel structure joint. The damping shaft 28 rotates the rotating bar 90 degrees counterclockwise, and the nut is put into the hexagonal block 10. The rotation of the motor 6 to the gear 7 is released, and the slider 4 slides to the right in the slide groove 3 through the rebound of the spring 27. At this time, the hexagonal block 10 with the nut is against the threaded opening at the other end of the steel structure. When the bolt gun 1 is started, the screw in the gun head penetrates the threaded opening in the steel structure joint and rotates into the nut in the hexagonal block 10 to install and fix the steel structure and the steel structure joint.

When the angle of the hexagonal block 10 and the nut is not right and cannot be engaged, the slide bar 21 is pushed into the hole groove 20. At this time, the hexagonal block 22 will leave the twelve-angle groove 24 and enter the circular groove 25. The slide bar 21 is rotated to drive the hexagonal block 22 to rotate in the circular groove 25, and at the same time drive the hexagonal block 10 to rotate fine-tune. After the fine-tuning, the slide bar 21 is released to make the spring 23 rebound, and the hexagonal block 22 is pushed into the twelve-angle groove 24 and engaged. At this time, the fine-tuned hexagonal block 10 can be engaged with the nut at the other end of the steel structure joint for disassembly.
