Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example 1

[0040] A grid truss steel member welding auxiliary device, such as Figure 1-Figure 3 Shown, including:

[0041] A base plate 1, and locking universal wheels 11 installed at the four corners of the bottom end of the base plate 1;

[0042] A control box 9 is installed on the substrate 1;

[0043] There are two support columns 2, and the two support columns 2 are symmetrically installed on the top of the base plate 1, and a support table 3 is rotatably installed on the two support columns 2. An adjustment component 4 is installed on the support column 2 to drive the two groups of support tables 3 to rotate around the support column 2, and a linear guide rail 31 is symmetrically installed on the support table 3. A slide plate 5 is slidably installed on the linear guide rail 31, and a clamping mechanism 6 is installed on the slide plate 5. A driving member 7 that drives the slide plate 5 to slide along the linear guide rail 31 is installed on the support table 3, and a rocker mechanism 8 is installed on the end of the support table 3 away from the support column 2.

[0044] like Figure 4 As shown, the clamping mechanism 6 includes a vertical baffle 61, which is fixedly mounted on one end of the slide 5 away from the supporting table 3, and a hydraulic rod 62 is fixedly mounted on the other end of the slide 5, and a sliding seat 63 is fixedly mounted on the telescopic end of the hydraulic rod 62, and a turning frame 64 (a rotating shaft or a rotating rod, as long as there is a rotating fulcrum, the turning frame 64 can be turned around the sliding seat 63) is rotatably mounted on the sliding seat 63, and a rotating motor 65 for driving the turning frame 64 to rotate is installed on the sliding seat 63, and a supporting and pressing assembly 66 is installed on the turning frame 64, and the rotating motor 65 and the hydraulic rod 62 are both electrically connected to the control box 9; a sliding groove (such as a T-shaped groove) that slides with the sliding seat 63 is provided on the slide 5.

[0045] like Figure 5-Figure 8As shown, the supporting and pressing assembly 66 includes a second hydraulic rod 661, which is fixedly mounted on the top of the turning frame 64 and electrically connected to the control box 9, and a lifting plate 662 is fixedly mounted on the telescopic end of the second hydraulic rod 661, and a positioning plate 663 is fixedly mounted on the lifting plate 662. A groove 601 is provided on one side of the positioning plate 663, and a bidirectional threaded rod 664 is rotatably mounted in the groove 601. A second motor 665 for driving the bidirectional threaded rod 664 to rotate is fixedly mounted on the top of the positioning plate 663, and the second motor 665 is electrically connected to the control box 9. Two groups of brackets 666 are symmetrically threaded on the bidirectional threaded rod 664, and the two groups of brackets 666 are both slidably matched with the groove 601, and a pressure wheel 667 (the pressure wheel 667 can rotate) is rotatably mounted on the end of the two groups of brackets 666 away from the positioning plate 663. The pressure wheels 667 installed on the two groups of brackets 666 are arranged to face each other and face outward.

[0046] It should be noted that: Figure 11 As shown, when in use, according to the butt joint angle of the welded steel structure, the adjusting component 4 is used to drive the support plate 3 on any one of the support columns 2 to rotate around the support column 2, and the angle of the support plates 3 on the two support columns 2 is adapted to the welding angle. Then the steel structure to be welded is placed on the slide 5 on the support plate 3. After placement, the sliding seat 63 is driven by the hydraulic rod 62 to slide along the slide 5 until the supporting and pressing component 66 presses the steel structure onto the vertical baffle 61. When the welded steel structure is an H-shaped steel, when the supporting and pressing component 66 is used, the hydraulic When rod 1 62 pushes the sliding seat 63 to slide, the two sets of brackets 666 are inserted into the belly of the H-beam. Then, motor 2 665 is controlled to drive the bidirectional threaded rod 664 to rotate. When the bidirectional threaded rod 664 rotates, the two brackets 666 are driven to move away from each other along the groove 601 until the pressure wheel 667 props up the inside of the H-beam. After propping up, the lifting plate 662 is driven by hydraulic rod 2 661 to adjust the height of the positioning plate 663 so that the bottom of the H-beam contacts the slide plate 5, completing the clamping. Then, hydraulic rod 1 62 is controlled to push it closer to the vertical baffle 61 for clamping. When welding is required, the driving member 7 is controlled to drive the slide plate 5 to slide along the linear guide 31 until the two H-beams to be welded are butted. After welding, when flipping is required for welding, the rotating motors 65 on the two support plates 3 are synchronously controlled to drive the turning frame 64 to flip.

[0047] It is worth noting that the entire welding butt installation operation here is controlled by the control box 9, which is equipped with a controller for controlling the movement of each motor and the corresponding operation buttons, as well as an electric hydraulic station for controlling the extension and retraction of the hydraulic rod, thereby realizing auxiliary welding operation control (which is the existing technology).

[0048] In this embodiment, a through slot is provided on the turning frame 64 for the lifting plate 662 to slide in, so that the hydraulic rod 661 can drive the lifting plate 662 to slide up and down along the through slot.

[0049] In the embodiments of the present invention, see Figure 1 、 Figure 4 and Figure 9 The adjustment component 4 includes a motor 41, which is fixedly mounted on one side of the support column 2, and a small gear 42 is fixedly mounted on the output end of the motor 41. A large gear 43 is fixedly mounted on one end of the support plate 3 that is rotatably connected to the support column 2, and the small gear 42 is engaged with the large gear 43. The motor 41 is electrically connected to the control box 9.

[0050] It should be noted that when the adjustment component 4 is in use, the motor 1 41 is controlled to drive the small gear 42 to rotate, and the small gear 42 is engaged with the large gear 43, thereby driving the support plate 3 to rotate around the support column 2, thereby adjusting the placement angle.

[0051] In the embodiments of the present invention, see Figure 1 and Figure 4 The driving member 7 includes a driving motor 71, which is fixedly mounted on the support plate 3 and electrically connected to the control box 9. A lead screw 72 is rotatably mounted on the support plate 3 and coaxially fixedly connected to the output end of the driving motor 71. The slide plate 5 is provided with a threaded through hole that is threadedly connected to the lead screw 72. The driving motor 71 is controlled to drive the lead screw 72 to rotate, and when the lead screw 72 rotates, the slide plate 5 slides along the linear guide rail 31.

[0052] In the embodiments of the present invention, see Figure 1 、 Figure 6 、 Figure 9-10 The rocker mechanism 8 includes a support arm 81, one end of the support arm 81 is hinged to the support table 3, and the other end of the support arm 81 is rotatably installed with an auxiliary roller 82. The bottom end of the support table 3 is rotatably installed with a winding shaft 83. One side of the support table 3 is installed with a motor 3 84 for driving the winding shaft 83 to rotate. The motor 3 84 is electrically connected to the control box 9. A steel wire rope 85 is wound around the winding shaft 83, and the end of the steel wire rope 85 facing away from the winding shaft 83 is tied to one end of the support arm 81 where the auxiliary roller 82 is installed.

[0053] It should be noted that when the rocker mechanism 8 is in use, after the H-shaped steel member is placed on the slide 5, the control motor 3 84 drives the reel 83 to rotate, thereby driving the wire rope 85 to reel in. The wire rope 85 then pulls the support arm 81 to lift the arm until the auxiliary roller 82 contacts the bottom of the H-shaped steel member, providing auxiliary support for the other end of the steel member, facilitating stable welding of large steel members. During the flipping process of the H-shaped steel member, the height of the H-shaped steel member changes, and the pressure wheel 667 supports the H-shaped steel. The strength of the internal support can be determined by setting a ballast. After flipping, the rocker mechanism 8 is adjusted to provide auxiliary support.

[0054] In this embodiment, a steering wheel 86 for guiding the wire rope 85 is installed on the support platform 3 to facilitate stable retraction and release of the wire rope 85.

[0055] Example 2

[0056] An operating method of a grid truss steel member welding auxiliary device comprises the following steps:

[0057] S1. Welding angle adjustment: Adjust the placement angle of the support plate 3 on any support column 2 according to the welding angle; specifically, the adjustment is made by starting the motor 1 41 to drive the small gear 42 to rotate, and the small gear 42 engages with the large gear 43, thereby driving the support plate 3 to rotate around the support column 2 until the support plate 3 and the support plate 3 on the other support column 2 are adjusted to the designed welding angle;

[0058] S2. Loading: Place the two grid steel members to be welded on the slides 5 of the support plates 3 on the two support columns 2, respectively, and use the rocker mechanism 8 for auxiliary support;

[0059] S3, clamping and docking; after completing step S2, the steel member placed on the support plate 3 is clamped by the clamping mechanism 6, and after clamping, the driving member 7 is used to drive the slide plate 5 to slide, aligning the welding position to complete the docking;

[0060] S4, butt welding: After completing step S3, welding is performed. When the welding position needs to be flipped during welding, the two rotating motors are controlled to run synchronously, and the rotating motor 65 of the clamping mechanism 6 can drive the turning frame 64 to flip, thereby flipping and adjusting the clamped steel member.

[0061] The working principle of the grid truss steel member welding auxiliary device provided by the present invention is as follows:

[0062] When in use, according to the butt joint angle of the welded steel structure, the adjusting component 4 is used to drive the support plate 3 on any support column 2 to rotate around the support column 2 until the angle of rotation with the support plate 3 on the other support column 2 is adapted to the welding angle, and then the steel structure to be welded is placed on the slide 5 on the support plate 3. After placement, the hydraulic rod 1 62 is driven to drive the sliding seat 63 to slide along the slide 5 until the steel structure is pressed and fixed on the vertical baffle 61 by the supporting and pressing component 66. When the welded steel structure is an H-shaped steel, when the supporting and pressing component 66 is used, when the hydraulic rod 1 62 pushes the sliding seat 63 to slide, the two sets of brackets 666 are inserted into the belly of the H-shaped steel, and then the motor 2 665 is controlled to drive the bidirectional thread When the rod 664 rotates, the two-way threaded rod 664 drives the two brackets 666 to move away from each other along the groove 601, and move away until the H-shaped steel is supported by the pressure wheel 667. After being supported, the lifting plate 662 is driven by the hydraulic rod 2 661 to adjust the height of the positioning plate 663 so that the bottom of the H-shaped steel contacts the slide plate 5 to complete the clamping. Then, the hydraulic rod 1 62 is controlled to push it close to the vertical baffle 61 for clamping. When welding is required, the driving part 7 is controlled to drive the slide plate 5 to slide along the linear guide rail 31 until the two H-shaped steels to be welded are butt-jointed. After welding, when flip welding is required, the rotating motors 65 on the two supporting plates 3 are synchronously controlled to drive the turning frame 64 to flip.

[0063] Furthermore, in order to improve the welding stability of large steel structures, after the H-shaped steel structure is placed on the slide 5, the control motor 3 84 drives the winding shaft 83 to rotate, thereby driving the wire rope 85 to reel in, and then the support arm 81 is pulled by the wire rope 85 to lift the arm until the auxiliary roller 82 contacts the bottom of the H-shaped steel structure to provide auxiliary support for the other side of the steel structure.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
