[0028] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions:

[0029] I. This invention uses a synchronous ball clamping mechanism to fix spherical nodes by clamping, thereby increasing the stability during welding operations and effectively reducing the requirement for the flatness of the spherical node surface. Then, a lifting clamping rod mechanism set on four U-shaped carriages initially clamps the rods. A split traction mechanism uses the power of the traction drive mechanism to pull the U-shaped carriages to move synchronously, so that the U-shaped carriages can drive the rods to connect synchronously with the spherical nodes, ensuring that the position of each rod on the equipment is relatively uniform. Then, the lifting clamping rod mechanism clamps and fixes the rods a second time for subsequent welding operations.

[0030] Second, the skid mechanism of this invention uses a skid-mounted method to assemble the four side bases and the central base, and uses a split traction mechanism to connect the U-shaped carriages on the four side bases to the traction drive mechanism on the central base, making the overall equipment easier to disassemble and assemble, reducing the difficulty of transportation and storage, and allowing the number of side bases and U-shaped carriages to be installed to be selected according to the actual working conditions, thus increasing the applicability of the equipment.

[0031] Third, this invention uses a docking adjustment component in conjunction with a synchronous ball clamping mechanism to drive the spherical node to move up, down, and rotate as a whole. After the welding of the four rods on the spherical node is completed, the rods are separated from the lifting clamping mechanism by lifting. Then, the angle of the spherical node is adjusted by rotation so that the space between the four rods on the spherical node can be used to continue welding the rods. Furthermore, the two lifting clamping mechanisms on the U-shaped carriage can be used to adjust the docking angle between the spherical node and the rods by lifting, so as to quickly assist the workers in performing spatial misalignment welding at eight angles on the spherical node.

[0083] When the horizontal welding operation of the four sides of the spherical node is needed, the spherical node is placed in the storage groove 602 by moving, and then the sliding disc 704 is pushed to slide in the guide groove 705 by the piston rod of the fourth hydraulic cylinder 706, so as to guide the sliding disc 704 in motion by the guide groove 705, and then the synchronous connecting rod 703 is moved by the sliding disc 704 in motion, and the arc-shaped clamping ball plate 701 is clamped and fixed to the spherical node by the synchronous connecting rod 703 through the second connecting block 702. Then the lifting clamp rod mechanism 3 is placed on the four side machine bases 102 and the four U-shaped carriages 103 by moving the rod member, and after the placement is completed, the first connecting block 306 is moved by the piston rod of the second hydraulic cylinder 305, the arc-shaped clamping plate 307 is moved by the first connecting block 306 in motion, and the outer wall of the rod member is extruded by the pressure rod wheel 82 cooperating with the spring 85 and the wheel seat 83, so as to preliminarily extrude and limit the rod member.

[0084] When the rod member is preliminarily extruded and limited, the first worm 504 is rotated by the output shaft of the traction drive motor 505, the first worm 504 in rotation drives the first worm gear disc 503 to rotate by the tooth pattern, the first worm gear disc 503 in rotation drives the turntable 501 to rotate by the connecting sleeve 502, the turntable 501 in rotation drives the connecting rod 403 to move by the traction connecting seat 401 cooperating with the sleeve ring 404, the U-shaped carriage 103 slides in the side machine base 102 by the connecting rod 403 in motion through the connecting support 402, the protruding part 90 is arranged to guide between the U-shaped carriage 103 and the side machine base 102, so that the U-shaped carriage 103 is synchronously moved by the split traction mechanism 4 cooperating with the power of the traction drive mechanism 5, the rod member extrudes and fits the outer wall of the spherical node by the lifting clamp rod mechanism 3 in motion, and the lifting clamp rod mechanism 3 can slide outside the rod member by pressure, so as to synchronously correct the position of the rod member on the four U-shaped carriages 103, to ensure that one end of each rod member can fully fit the spherical node, then the first connecting block 306 is pushed by the second hydraulic cylinder 305 to drive the arc-shaped clamping plate 307 to continue moving, the arc-shaped clamping plate 307 in motion clamps the rod member, and the wheel seat 83 is slid into the sliding groove 81 by the pressure rod wheel 82 under the action of pressure, the wheel seat 83 in motion drives the spring 85 to be compressed, so as to clamp and fix the position of the rod member, so as to carry out the welding work between the rod member and the spherical node subsequently.

[0086] In order to ensure the stability of the spatial misalignment of the rod, the arc-shaped clamping plate 307 can be used to clamp and fix the rod by driving the second hydraulic cylinder 305 while lifting the rod. After the rod is lifted to the specified height, the first hydraulic cylinder 303 on the side away from the center seat 101 is used to push the compensation connecting piece 302 to drive the support rod frame 301 to continue to move, so that the whole rod is inclined to the spherical node. Then the split traction mechanism 4 is used to pull the U-shaped carriage 103 by the traction driving mechanism 5, and the moving U-shaped carriage 103 drives one end of the inclined rod to abut to the surface of the spherical node. It should be noted that a groove with a certain slope should be opened in one end of the rod in advance to avoid the protruding part of the rod from contacting the spherical node in advance when moving horizontally, which may cause the movement to be blocked and the full butt joint operation to be unable to be completed.

Any person skilled in the art can easily think of various changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
