[0036] The working principle of the welding system for the stiffened node plate on the steel truss beam is as follows:

[0037] First, before welding, the staff first put the device on the steel truss to be welded, and then the node plate material is installed in place through the outside, and then the cable pipeline of the power supply system connects the device with the external power supply and hydraulic system, which can provide the power required for the operation of the device;

[0038] Second, the core controller 6 controls the oil cylinder 84 to pull the gear ring 83 and the connecting shaft 85 on its left and right sides to adjust the distance. The sliding sleeve shaft 81 and the sliding shaft body are driven to move. The sliding sleeve shaft 81 is connected to the inner and outer shaft bodies. The convex wheel 7 moves with the displacement to make the stepped wheel body close to the beam body. At the same time, the double-shaft motor in the self-propelled assembly 1 is driven to drive the driven gear 82 and the gear ring 83 to mesh through the sliding sleeve shaft 81. The gear ring 83 and the connecting shaft 85 are driven to rotate, and the coil chain 86 and the convex wheel 7 are driven to follow the transmission. The convex wheel 7 drives the self-propelled assembly 1 to walk on the beam body. During the transmission of the coil chain 86, the chain plate at the bottom of the coil chain 86 moves up due to gravity and contacts the button control panel 88. The power is introduced into the coil chain 86 through the elastic rod 87 to make the coil inside it energized and keep the magnetic state. The coil chain 86 and the beam body maintain a certain adsorption state to improve the walking strength of the self-propelled assembly 1;

[0039] Third, during the displacement of the self-propelled assembly 1, the cast iron plate 55 is contacted by the cable-stayed beam on the steel truss and rotates to tightly adhere to the surface of the cable-stayed beam. The cast iron plate 55 rotates, and the T-shaped shaft 53 rotates to change the pressure in the upper and lower chambers of the ring-shaped oil cylinder 52. At this time, the pressure sensor 54 monitors the pressure in the upper and lower chambers of the ring-shaped oil cylinder 52, and analyzes and judges the turning direction and inclination angle of the cast iron plate 55 using the monitoring data of the pressure sensor 54. The angle between the steel truss and the cable-stayed beam above it can be obtained. At the same time, the cast iron plate 55 can be adsorbed and tightly adhered to the cable-stayed beam by energizing the coil 56, and the fixing effect of the whole device is improved by the cooperation of the convex wheel 7 and the adsorption assembly 8. After completing the displacement and walking, the first servo motor 41 drives the sliding block 43 to displace on the top plate 3 through the transmission screw rod 42. Since the retraction structure of the adsorption assembly 8 is provided, the transmission amount of the first servo motor 41 driving the top plate 3 can be obtained by the retraction data of the adsorption assembly 8 and the thickness data of the sliding groove of the top plate 3;

[0040] Fourth, the welding assembly 45 and the polishing assembly 46 are pushed by the push oil cylinder 44 to approach the welding point position of the node plate in turn, the welding assembly 45 can perform the welding action on the node plate along the side of the steel truss and the cable-stayed beam under the cooperation of the first servo motor 41 and the first adjusting assembly 2, the image is collected by the first camera 452, then the polishing head 464 and the coil sleeve shaft 465 are driven to rotate by the second servo motor 462 through the worm gear assembly 463, the polishing head 464 can polish the welding position during the rotation, and the second camera 466 can adjust the angle and collect the image of the polishing position when the coil inside the coil sleeve shaft 465 is electrified.

[0041] The welding system for the stiffened node plate on the steel truss is improved, the front assembly 5 is arranged on the top side of the self-walking assembly 1, the detection between the pressure sensor 54 and the cast iron plate 55 can obtain the angle between the steel truss and the cable-stayed beam above the steel truss, and the fixing effect of the whole device is improved through the cooperation of the cast iron plate 55, the convex wheel 7 and the adsorption assembly 8; the adsorption assembly 8 is arranged below the self-walking assembly 1, the clamping type convex wheel 7 is adopted, and the walking strength of the self-walking assembly 1 on the steel truss is improved through the adsorption cooperation of the adsorption assembly 8; the second adjusting assembly 4 is arranged on the top side of the self-walking assembly 1, the welding assembly 45 and the polishing assembly 46 are pushed by the push oil cylinder 44 to approach the welding point position of the node plate in turn and perform the processing procedure, and the welding and monitoring efficiency of the node plate is improved.
