Description

Technical Field

[0001] The present invention relates to the technical field of bridge construction, and in particular to a device for quickly splicing and welding a spatial hexagonal variable-section bending-torsion steel box. Background Art

[0002] The spatial hexagonal variable-section bending-torsion steel box is a complex steel structure form, which is usually used in long-span bridges, special-shaped buildings or special-shaped public facilities. It is characterized by complex geometric shape and the integration of cross-sectional changes, spatial bending and torsion, etc., which places high demands on design, manufacturing and construction.

[0003] The existing bridge's main arch ribs are composed of two steel arch ribs per span. The arch ribs of the seven spans have smooth lines, and the arch rib centerlines and contours are all spatial spline curves. The arch ribs are all hexagonal steel box structures with arc decorative panels on top. The main arch ribs are continuous arcs. The hexagonal variable-section steel box girders are docked in the air, making it difficult to determine the center of gravity. The docking angles need to be adjusted multiple times, making it impossible to dock accurately. Traditional trial assembly relies on empirical corrections. The deviation between the BIM model and the actual scene requires multiple hoisting-measurement-adjustment cycles, which prolongs the construction period. After docking, manual welding is required. The arc lines are difficult to weld and the weld trajectory is complex. The arc steel box docking joint is a three-dimensional spatial curve. Manual welding cannot ensure consistent penetration depth and weld smoothness. High-altitude welding relies on manual operation, and the weld quality is limited by the worker's skill level. Summary of the Invention

[0004] Based on the technical problems that the existing steel box splicing cannot be accurately docked, traditional trial assembly relies on experience correction, empty welding relies on manual operation, and the weld quality is limited by the workers' skill level, the present invention proposes a spatial hexagonal variable-section bending and torsion steel box rapid splicing and welding equipment.

[0005] The present invention provides a spatial hexagonal variable-section bending and torsion steel box rapid splicing and welding device, comprising a steel box, the outer surface of which is provided with a walking device, a deflection device and a welding device.

The walking device includes an adjusting mechanism and a moving mechanism. The adjusting mechanism adjusts the position of the moving mechanism.

[0007] The deflection device is located on the outer surface of the walking device and adjusts the position of the walking device on both sides. The deflection device includes a deflection mechanism and a self-locking mechanism. The deflection mechanism drives the walking device to deflect up and down, and the self-locking mechanism self-locks the deflection mechanism.

[0008] The welding device is located on the outer surface of the walking device and welds the spliced ​​steel boxes. The welding device includes a bypass mechanism and a welding assembly. The bypass mechanism drives the welding assembly to move around the steel box, and the welding assembly welds two adjacent steel boxes.

[0009] Preferably, the adjustment mechanism includes a support frame, which is arranged on the outer surface of the steel box, a control shell is fixedly installed on the upper surface of the support frame, and a control motor is fixedly installed on the inner wall of the control shell, the outer surface of the control shell is rotatably connected to a drive rod with a bevel gear through a bearing, one end of one drive rod and one end of the output shaft of the control motor are fixedly installed through a coupling, one end of the two drive rods are connected to the transmission through the cooperation of a chain and a sprocket, the outer surface of the support frame is rotatably connected to a gear set with a bevel gear through a bearing seat, and the bevel gear of the gear set is engaged with the bevel gear of the drive rod.

[0010] Through the above technical solution, after the driving rod is driven to rotate by controlling the motor, the driving rod drives another driving rod to rotate through the cooperation of the sprocket and the chain, and the gear set can be driven to rotate through the transmission of the bevel gear.

[0011] Preferably, the moving mechanism includes a rack rack, the outer surface of the rack rack is slidably plugged into the inner wall of the support frame, the rack of the rack rack is engaged with the gear of the gear set, and a driving roller assembly is fixedly mounted on the outer surface of the rack rack.

[0012] Through the above technical solution, after the rack rack is engaged with the gear set, the rotation of the gear set can drive the rack rack to move, so that the driving roller assembly fits the outer surface of the steel box, making it convenient for the support frame to be sleeved on the outer surface of the steel box. After contacting both sides of the steel box, the support frame can be fixed on the outer surface of the steel box. The driving roller assembly is driven by the motor through the gear set to rotate the roller, so that the support frame can move on the outer surface of the steel box.

[0013] Preferably, the deflection mechanism includes a deflection connecting plate, one end of the deflection connecting plate is fixedly mounted on the outer surface of the support frame, the outer surface of the deflection connecting plate is hinged with a deflection shell through a pin, the outer surface of the deflection shell is fixedly mounted on the outer surface of another support frame, the outer surface of the deflection shell is hinged with a deflection connecting block group through a pin, the deflection connecting block group is composed of multiple connecting blocks hinged end to end, and one end of the deflection connecting block group is hinged to the outer surface of the support frame through a pin.

The tooth grooves between the main locking block and the auxiliary locking block can increase the friction and the clamping force. After the rack of the main locking block moves, the transmission gear drives the movement of the rack of the auxiliary locking block, so that the main locking block and the auxiliary locking block can move relative to or in the opposite direction.

[0020] Through the above technical solution, in order to push the main locking block to move, the pushing block can push the wedge block to move after it rises, and the wedge block pushes the main locking block to squeeze the spring and release the fixation of the wire rope.

[0024] Through the above technical solution, in order to weld the steel box, the winding gear ring is rotated on the mounting frame, and the winding gear ring drives the welding assembly to rotate, and welding is performed around the weld.

[0025] Preferably, the welding assembly includes a connecting frame, a robotic arm and a welding gun assembly, the connecting frame is fixedly mounted on the outer surface of the orbiting gear ring, the robotic arm is fixedly mounted on the outer surface of the connecting frame, and the welding gun assembly is fixedly mounted on one end of the robotic arm.

[0026] Through the above technical solution, the position of the distance from the weld can be adjusted by the robotic arm, which facilitates precise welding of the welding gun assembly.

[0029] 2. By setting a deflection device, rapid docking and welding can be facilitated. The wire roller can drive the wire rope to be wound through the drive of the winding motor, so that the flexible deflection connecting block group becomes hard after being tightened. After the three groups of deflection connecting block groups are tightened to different degrees, the connected support frame can be deflected up and down to different degrees, so that the degree of inclination of the support frame can be adjusted according to the position of the docked steel box. The release of the wire rope facilitates the deflection connecting block group to become soft, which facilitates the movement of the support frame. The cooperation of the deflection connecting block group and the wire rope can drive the walking devices at both ends to adjust the angle, and the welding of the welds at the docking point is completed through the middle welding device, which solves the technical problems that the existing steel box splicing cannot be accurately docked, the empty welding relies on manual operation, and the weld quality is limited by the workers' skill level.

A secondary locking block 53 with a rack is slidably inserted into the inner wall of the self-locking shell 5, and both the main locking block 51 and the secondary locking block 53 have teeth and grooves to increase the friction with the wire rope 45. The inner wall of the secondary locking block 53 is slidably inserted into the outer surface of the main locking block 51, and the inner wall of the self-locking shell 5 is rotatably connected to a transmission gear 54 through a bearing, and the transmission gear 54 is respectively engaged with the rack of the main locking block 51 and the rack of the secondary locking block 53.

[0053] Specifically, in order to push the main locking block 51 to move, a wedge block 55 is fixedly installed at one end of the main locking block 51, and a pushing block 56 with a rack is slidably inserted into the inner wall of the self-locking shell 5.

[0058] Working principle: When the arch ribs of the bridge need to be docked, the support frame 2 is hoisted and sleeved on the outer surface of the first section of the steel box 1 after the splicing is completed. The control motor 22 in the control housing 21 on the support frame 2 is controlled. The control motor 22 is started to drive a driving rod 23 to rotate. The rotation of the driving rod 23 drives another driving rod 23 to rotate through the transmission of the chain and the sprocket. The bevel gear on the driving rod 23 can drive the gear set 24 to rotate. The gear set 24 can drive the rack rack 3 to move. After the rack rack 3 moves, it pushes the driving roller assembly 31 to move. After the driving roller assembly 31 contacts the two surfaces on both sides of the steel box 1, When the support frame 2 is erected on the steel box 1 and the next section of the steel box 1 is moved to one end of the steel box 1 to be spliced ​​by the crane, the rotary motor 62 in the deflection housing 41 is started, which drives the rotating gear ring 61 on the support roller 6 to rotate, and drives multiple transmission rods 57 to rotate.

The main locking block 51 and the secondary locking block 53 move in opposite directions, releasing the clamping of the wire rope 45;

[0059] The reel 43 is rotated by the winding motor 43, and the wire roller 44 is driven to reel in the corresponding wire rope 45. After the deflection connecting block group 42 is tightened, the soft state becomes hard after the wire rope 45 is reeled in to different degrees, and the support frame 2 is deflected. After the support frame 2 is deflected toward the side of the docking steel box 1, the driving roller assembly 31 is started, and the deflected support frame 2 is sleeved on the outside of the steel box 1, and the driving roller assembly 31 stops rolling. The driving roller assembly 31 located on the support frame 2 outside the lifted steel box 1 is located on both sides of the steel box 1. After the driving roller assembly 31 moves relatively, the outside of the steel box 1 is clamped, so that the steel box 1 can be clamped. Through the winding adjustment of the wire rope 45 and the cooperation of the driving roller assembly 31, the support frame 2 on the lifted steel box 1 is moved and the angle of the clamped steel box 1 is deflected and adjusted, so that one end of the steel box 1 is docked with one end of the fixed steel box 1.

[0060] After the lifted steel box 1 is fixed and the entire arch rib is erected, the support frames 2 on both sides are respectively located on both sides of the welds to be welded, so that the mounting frame 7 is located above the welds. The orbiting gear ring 71 in the mounting frame 7 rotates when the orbiting motor 72 is started, driving the welding gun assembly 82 to weld around the weld, and the robotic arm 81 adjusts the position of the welding gun assembly 82.
