Description

Technical Field

[0001] This application relates to the technical field of steel frame welding, and in particular to vertical steel frame welding robots. Background Technology

[0002] A steel frame is a combination of multiple steel bars to form a complete grid, figuratively called a steel cage or steel skeleton. A complete steel frame helps to restrain concrete and improve the integrity of concrete components.

[0003] Traditional welded steel frames involve arranging steel bars on the ground and then welding them on the ground.

[0004] Workers need to move horizontally constantly to weld steel frames on the ground to complete each welding point. The constant horizontal position changes affect welding efficiency, and the welding quality is related to the worker's skill level. Summary of the Invention

[0005] To improve welding efficiency and ensure welding quality during steel frame welding, this application provides a vertical steel frame welding robot.

[0006] The vertical steel frame welding robot provided in this application adopts the following technical solution:

[0007] A vertical steel frame welding robot, comprising a lifting assembly, a support frame, a rebar hanger, and a robot body for welding the steel frame;

[0008] The lifting assembly includes a lifting frame, a first rack, a first motor, and a first gear. The first motor is fixedly connected to the robot body, the first gear is fixedly ring-fitted on the rotating shaft of the first motor, the first rack is vertically fixed on the lifting frame, the first gear meshes with the first rack, and the robot body is slidably connected to the lifting frame.

[0009] The support frame is slidably disposed on one side of the lifting frame, and the support frame slides in the horizontal direction; when the support frame moves, the shortest distance between the robot body and the support frame remains unchanged.

[0010] The rebar rack is vertically mounted on a support frame and is used for placing rebars.

[0011] By adopting the above technical solution, the rebar rack is placed vertically on the support frame. Then, the longitudinal and transverse reinforcing bars required for welding the steel frame are placed on the rebar rack. The robot body is then activated to weld the longitudinal and transverse reinforcing bars. When it is necessary to move the welding position, the support frame can be moved to change the horizontal direction of the welding position. The first motor is then activated, and the first motor, through the transmission of the first gear and the first rack, changes the vertical position of the robot body. Ultimately, the vertical direction of the welding position is changed, and the welding robot can ensure a stable welding effect. The entire device replaces manual hand-held welding torch movement, thereby improving the welding efficiency of the steel frame welding and ensuring the welding quality.

[0012] Optionally, the rebar rack is a rectangular frame, with uprights slidably arranged inside the rebar rack. The uprights slide along the length of the bottom edge of the rebar rack, and multiple bracket assemblies slide on the uprights. Adjacent bracket assemblies slide along the length of the uprights and are spaced apart.

[0013] The bracket assembly includes a drag rod, a U-shaped plate, a limiting bolt, and a first set screw handle. The limiting bolt passes through the open end of the U-shaped plate and is looped around the upright along with the U-shaped plate. The drag rod is set perpendicular to the upright, with one end fixed to the U-shaped plate and the other end in a cantilevered state. The first set screw handle is used to lock the position of the U-shaped plate on the upright.

[0014] By adopting the above technical solution, the limiting bolt and the U-shaped plate form a closed ring, which fits onto the upright, allowing the drag rod to slide on the upright without detaching. By rotating the first set screw handle, the U-shaped plate is fixed to the outer wall of the upright, thus limiting the drag rod after it slides to the appropriate position. After adjusting the position of the drag rod, it can accommodate steel bars of different shapes and spacings, allowing the steel bars to be placed on the drag rod.

[0015] Optionally, the bottom inner wall and the top inner wall of the rebar swing frame are both fixed with slide rails. The length direction of the slide rails is set along the length direction of the bottom or top of the rebar swing frame. A slider is fixed at the end of the upright. The slider slides on the slide rail. A second set screw handle for locking the position of the slider is provided on the slider.

[0016] By adopting the above technical solution, the slider slides on the slide rail. When it slides to the designated position, the slider is positioned on the slide rail by rotating the second set screw handle, thereby realizing the positioning after the position of the upright is adjusted. The position of the upright can be adjusted in the horizontal direction to adapt to the placement of steel bars with different shapes and different spacings.

[0017] Optionally, a limit block is fixed on the tow rod, the limit block is located at the top of the tow rod and near the U-shaped plate, and the end of the tow rod away from the U-shaped plate gradually tilts upward.

[0018] By adopting the above technical solution, the upward tilt of the cantilevered end of the tow rod makes it difficult for the reinforcing bars placed on the tow rod to slip off the tow rod, while the limiting block also has the effect of limiting the reinforcing bars placed on the tow rod.

[0019] Optionally, a magnetic strip is fixed to the top of the tow rod, and the magnetic strip is located between the limiting block and the raised end of the tow rod.

[0020] By adopting the above technical solution, the steel bars placed on the tow bar are magnetically attracted by the magnetic strip, which further improves the stability of the steel bars placed on the tow bar.

[0021] Optionally, the bottom inner wall of the rebar rack is provided with a U-shaped strip and a movable plate. The length direction of the U-shaped strip is along the length direction of the bottom of the rebar rack. The U-shaped strip is fixed upside down on the rebar rack. Multiple first holes are opened on the U-shaped strip. Adjacent first holes are spaced apart along the length direction of the U-shaped strip. The length direction of the first hole is perpendicular to the length direction of the U-shaped strip. The movable plate is slidably mounted on the U-shaped strip. The sliding direction of the movable plate is along the length direction of the U-shaped strip. Second holes are opened on the movable plate. Adjacent second holes are spaced apart along the length direction of the movable plate. The length direction of the second hole is perpendicular to the length direction of the movable plate. The distance between adjacent second holes is the same as the distance between adjacent first holes.

[0022] By adopting the above technical solution, the horizontal bars are placed on the drag bar, and the longitudinal bars are inserted into the first hole. The U-shaped strip provides the opening space for the first hole. The sliding plate is moved to make the first hole and the second hole misaligned, thereby adjusting the size of the space at the bottom of the longitudinal bar that can be inserted, realizing the limitation of the longitudinal bar after insertion, and also enabling the bar rack to adapt to bars of different diameters.

[0023] Optionally, a first guide rail is provided between the support frame and the ground, and a second rack is fixed on the first guide rail. The second rack is arranged along the length direction of the first guide rail. A second motor is vertically fixed on the outer wall of the support frame, and a second gear is fixed on the rotating shaft of the second motor. The second gear and the second rack mesh with each other, and the support frame slides on the first guide rail.

[0024] By adopting the above technical solution, the second motor rotates, and the second motor achieves the sliding of the support frame on the first guide rail through the meshing transmission of the second gear and the second rack. The movement of the support frame drives the movement of the steel bar swing frame, thereby realizing the movement of the steel frame. This facilitates the welding of each welding point on the steel frame, improves the welding efficiency of the steel frame, and also facilitates the subsequent transportation of the steel frame after the welding is completed.

[0025] Optionally, a second guide rail is provided between the lifting frame and the ground, and the lifting frame slides on the second guide rail; the second guide rail is arranged parallel to the first guide rail.

[0026] By adopting the above technical solution, the lifting frame can move on the second guide rail, realizing the effect of the robot body moving relative to the steel frame, and further improving the welding efficiency of the robot body to each welding point on the steel frame.

[0027] Optionally, the top of the support frame is provided with a flipping shaft, which is horizontally positioned and located at the top of the vertical side wall along the length of the support frame. A hanging ear is fixed on the vertical side wall of the steel bar swing frame. A bracket is provided on the side of the support frame away from the robot body, and a hydraulic cylinder is provided on the bracket. One end of the hydraulic cylinder body is rotatably connected to the bracket. The rotation shaft of the hydraulic cylinder is parallel to the flipping shaft. A movable pin is inserted into one end of the hydraulic cylinder piston, and the movable pin is inserted and connected to the hanging ear.

[0028] By adopting the above technical solution, the bracket provides a support point for the hydraulic cylinder. After the movable pin is inserted into the hanging lug, the hydraulic cylinder piston moves, causing the steel bar swing frame to change from a vertical state to a horizontal state. When the steel frame is welded, the steel bar swing frame is in a vertical state. After the steel frame is welded, the steel bar swing frame rotates and adjusts to a horizontal state, so that the gantry crane in the factory can lift the steel frame away. The ability of the steel bar swing frame to rotate facilitates the subsequent transportation of the steel frame.

[0029] Optionally, the robot body is equipped with supplementary lighting.

[0030] By adopting the above technical solution, the fill light is turned on to illuminate the welding position, so that the robot body can perform welding in a bright environment.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. The robot body, together with the lifting components and the second guide rail, enables horizontal and vertical position changes during the welding of the steel frame, improving welding efficiency while ensuring consistent welding quality.

[0033] 2. The setting of the tilting shaft and hydraulic cylinder allows the rebar swing frame to have two states: when the rebar swing frame is in the vertical state, it is during the welding of the steel frame; when the rebar swing frame is in the horizontal state, it is when the steel frame has been welded and needs to be hoisted and transported.

[0034] 3. The bracket assembly can adapt to different shapes and spacings of steel bars, and plays a supporting and limiting role for the steel bars. Attached Figure Description
