[0014] 2. The steel structure welding docking equipment used in the welding construction of the building steel structure is provided with a mounting plate, a connecting plate and a first electric hoist reel.

At this time, the mounting plate is lifted to the designated docking position, and the beam can be lifted in a relatively narrow space without using a large lifting equipment, so that the beam and the vertical column can be docked.

[0015] 3. The steel structure welding and docking equipment for building steel structure welding construction is provided with side blocks, guide rails and mounting parts. The guide rails are placed in the grooves on the surface of the vertical columns, and then one end of the fixing screws is passed through the slots and through holes and passed out to the outside of the slots on the other side. Then the bolts are screwed on the outside of the tail ends of the fixing screws to fix the guide rails on the ground. Then one end of the second traction rope is passed through the lifting ring and the end of the second traction rope is tied up. Then one end of the first traction rope is passed through the guide wheel and tied to the lifting point on the beam. Then the output end of the driving motor drives the walking wheel to rotate, so that the walking wheel moves up along the inside of the walking rail. The walking wheel Matching teeth and tooth grooves are provided on the walking rails, so that the fixed seat, side block, fixed plate, rotating arm, mounting plate, connecting plate, rotating shaft and guide wheel can be driven upward by the walking wheel. While the guide wheel moves upward, the first electric hoist winder releases the first traction rope. When the mounting plate moves to the specified position, the operator uses a scaffolding or other climbing work platform to fix the mounting part on the vertical column with a first screw fixing structure to fix the position of the guide wheel. There is no need for the staff to carry more lifting components when climbing, which ensures the safety of the staff when climbing. The lifting components can be automatically raised and lowered on the vertical column.

[0016] 4. The steel structure welding butt joint equipment used for welding construction of building steel structures is provided with a second traction rope, a guide roller and a storage box. When in use, the worker at the bottom puts the tool into the storage box through the taking port, and then starts the second electric hoist winder to make the second electric hoist winder wind up the second traction rope, so that the second traction rope drives the lifting ring and the storage box to move up to a specified height, so that the worker on the climbing work platform can open the sealing plate and take out the tools or parts needed from the storage box through the taking port for use. Therefore, the worker does not need to carry the tools or parts needed when climbing, thereby improving the safety of the worker.

[0017] 5. The steel structure welding docking equipment for building steel structure welding construction is provided with a lifting ring, a second traction rope and a guide wheel. After the docking is completed, the staff separates the first traction rope from the lifting point on the beam, and the telescopic end of the electric telescopic rod drives the first moving block to move downward, so that the first moving block pushes the electric telescopic rod and the second friction block to move downward, and at the same time, the piston column moves, pushing the liquid inside the piston cylinder into the liquid bag through the connecting pipe, so that the liquid bag expands and pushes the second moving block and the first friction block to move upward, and the rotation of the rotating shaft is limited by the second friction block and the first friction block, and one end of the first traction rope is clamped by the clamping block and the guide wheel, and then the staff unscrews the first screw fixing structure, and then the output end of the first servo motor drives the rotating arm to rotate, so that the mounting plate and the mounting part rotate to one side of the side block, and then the side block moves downward, and when the side block moves down to the designated position After the lifting, the telescopic end of the electric telescopic rod pushes the first moving block to move upward, so that the first moving block pushes the piston column to move upward, so that the liquid inside the liquid bag is sucked into the piston cylinder through the connecting tube, so that the reset spring pushes the second moving block and the first friction block to move downward, and at the same time, the telescopic end of the electric telescopic rod pushes the first moving block, the clamping block and the first friction block to move upward, thereby releasing the limit on the first traction rope, and then the first traction rope is reeled in by the first electric hoist reel, and the second traction rope is separated from the lifting ring, and the second traction rope is reeled in by the second electric hoist reel, so as to facilitate the disassembly and transportation of the device, thereby facilitating its use. At the same time, when descending, the first traction rope is limited by the electric telescopic rod and the guide wheel as well as the second friction block and the first friction block, so as to prevent the first traction rope from falling when moving downward and causing harm to the staff on the ground.
