Description

Technical Field

[0001] The invention relates to the technical field of building steel structure welding construction, in particular to steel structure welding butt joint equipment used in building steel structure welding construction. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. It is widely used in large factories, stadiums, super high-rise buildings and other fields. When docking beams, it is necessary to use lifting equipment to lift them for docking and then weld them.

[0012] The present invention provides a steel structure welding butt joint device for use in welding construction of building steel structures, which has the following beneficial effects:

[0013] 1. The steel structure welding and docking equipment used in the steel structure welding construction of this building. When in use, the worker stands inside the workbench, and then the workbench is raised by a lifting vehicle so that the worker can weld with a welding gun. During welding, the pump is started, and the welding gas is sucked in through the suction head, and then discharged into the air filter through the pump.

[0014] 2. The steel structure welding and 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. When the first electric hoist reel is started, the first traction rope is reeled, so that the first traction rope lifts the beam to the bottom of the mounting plate through the lifting point. At this time, the beam is blocked by the mounting plate and cannot continue to move up. At this time, the mounting plate is lifted to the designated docking position. 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 the building steel structure welding construction is provided with side blocks, guide rails and mounting parts. The guide rails are placed into the grooves on the surface of the vertical columns. One end of the fixing screw is passed through the slots and through holes and out to the outside of the slots on the other side. The bolts are then screwed onto the outside of the tail ends of the fixing screws to fix the guide rails on the ground. One end of the second traction rope is passed through the lifting ring and the end of the second traction rope is tied up. One end of the first traction rope is passed through the guide wheel and tied to the lifting point on the beam. 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 and The walking rails are provided with matching teeth and tooth grooves, so that the fixed seat and side blocks and fixed plates, the rotating arm and the mounting plate, the connecting plate and the rotating shaft and the guide wheel can be driven to move upward through the walking wheels. 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 a large number of 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 and docking equipment used for building steel structure welding construction 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 access port, and then the second electric hoist winder is started, so that the second electric hoist winder winds up the second traction rope, so that the second traction rope drives the lifting ring and the storage box 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 that need to be used from the storage box through the access port for use. Therefore, the worker does not need to carry the tools or parts that need to be used when climbing, thereby improving the safety of the worker.

[0017] 5. The steel structure welding docking equipment for the welding construction of the building steel structure 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. 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 moves down to the designated position when the side block moves down. At the same time, when descending, the first traction rope is limited by the electric telescopic rod, the guide wheel, 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.
