Description

Technical Field

[0002] In the field of cargo box welding, traditional orbital welding technology is widely used. The existing orbital welding method generally includes the following steps: First, workers lay welding tracks on the ground or at the welding position to be processed. According to the welding length requirement, multiple sets of track segments with different lengths need to be spliced into an integral track. After the track laying is completed, a movable welding machine is installed on the track, and the welding torch head is precisely aligned with the weld seam by adjusting the position of the welding torch. Subsequently, the welding machine cart is driven to move along the track to achieve continuous welding of the cargo box welding position;

[0050] By driving the supporting plate 206 to move through the supporting threaded rod 205 in the supporting component, the support of the main track 201 is realized.

[0069] When the present invention is specifically implemented:

[0070] S1. Track assembly. Since the main track 201 is pre-connected to the switching track 302 by plugging, now only the installation of the slave track assembly 400 needs to be carried out. The installation quantity of the slave track assembly 400 is installed according to the welding requirements. During installation, first connect the first group of slave track assemblies 400 to one end of the switching assembly 300, and then install the second group of slave track assemblies 400 at one end of the first group of slave track assemblies 400;

[0071] When installing the first set of slave roller assemblies 400, first, pull the locking damping rod 310. The locking damping rod 310 will drive the locking rod 311 to move, so that one end of the locking rod 311 moves out from one side inside the second docking hole 309. At this time, insert the second docking block 402 at one end of the extension track 401 into the second docking hole 309. After insertion, release the locking damping rod 310, so that one end of the locking rod 311 is inserted into the connection hole 403, and then the extension track 401 can be fixed to the switching track 302, which also realizes the connection of the main rail assembly 200, the switching assembly 300 and the first set of slave rail assemblies 400. The connection of the second set of slave rail assemblies 400 is the same as that of the first set of slave rail assemblies. Insert one end of the second set of slave rail assemblies into one end of the first set of slave rail assemblies to complete the connection;

[0072] S2. Adjust the level of the overall track. When adjusting, first rotate the support threaded rod 205. The rotation of the support threaded rod 205 will drive the support plate 206 to move downward under the action of the guide rod 207 and contact the ground, thereby realizing the support of the track. At the same time, the level of the track is also adjusted to prevent the track from tilting and making it inconvenient for the movement of the moving trolley 100;

[0073] S3. When the track needs to be temporarily moved or briefly stored later, pull the slave rail assembly 400 at this time. The slave rail assembly 400 will drive the switching track 302 to move. When the switching track 302 moves, it will drive the cylinder 307 and the first docking block 308 to move respectively. When the cylinder 307 moves, it will cross the arc-shaped auxiliary block 306, and when the first docking block 308 moves, it will disengage from the first docking hole 202. After disengagement, rotate the slave rail assembly 400 at this time, so that the slave rail assembly 400 and the switching track 302 are perpendicular to the main track 201, which realizes temporary storage and also facilitates its movement through the main track 201, reducing the obstruction of the floor area; The disassembly of the slave rail assembly 400 and the switching assembly 300 will facilitate later storage and adaptation to the welding of cargo boxes of different lengths;

[0074] S4. Increase the height of the height increasing component 600. First, move the unlocking rod 614. When the unlocking rod 614 moves, it will drive the angle plate 612 to move, thereby driving the swing rod 611 to rotate. When the swing rod 611 rotates, it will drive the inserting rod 610 to move, so that one end of the inserting hole 610 is received into the hollow inserting block 609. After the reception, at this time, the staff can align one end of the hollow inserting rod 609 with the square hole 603 and insert it inward. After the insertion, at this time, release the unlocking rod 614. Under the action of the downward pressing damping rod 613, the angle plate 612 drives the swing rod 611 and the inserting rod 610 to move, so that one end of the inserting rod 610 is inserted into the round hole 604, thus completing the docking of the first rectangular rod 601 and the second rectangular rod 605. When the height needs to be increased subsequently, the second rectangular rod 605 of the next group can be inserted into the inserting hole 607 in the second rectangular rod 605 of the previous group in the above manner, and then fixed and connected together through the column hole 608 to complete the connection of multiple groups of the second rectangular rods 605;

[0075] S5. Adjust the height position of the welding component 700. When adjusting, first, insert one end of the second inserting rod 708 into the first height hole 602 or the second height hole 606. At this time, the second U-shaped frame 706, the welding hand 710, the welding gun 711 and the wire reel 712 can be fixed at the designated positions of the first rectangular rod 601 and the second rectangular rod 605. At this time, the staff rotates the bidirectional threaded rod 714, causing the two internal threaded blocks 715 to move and no longer be threadedly connected to the adjusting threaded rod 705. After the two internal threaded blocks 715 are separated respectively, at this time, the staff pulls the first inserting rod 703, so that one end of the first inserting rod 703 is disengaged from the first height hole 602 or the second height hole 606, and then moves the first U-shaped frame 701 upward or downward. When the first U-shaped frame 701 moves, it will drive the adjusting threaded rod 705 to move upward or downward. When the first U-shaped frame 701 moves to a suitable position, at this time, release the first inserting rod 703, so that the first inserting rod 703 is inserted into the corresponding first height hole 602 or second height hole 606. After the insertion, at this time, rotate the bidirectional threaded rod 714 again, so that the two internal threaded blocks 715 form a threaded sleeve. At this time, the staff can pull the second inserting rod 708, so that one end of the second inserting rod 708 is disengaged from the first height hole 602 and the second height hole 606. After the disengagement, at this time, rotate the adjusting threaded rod 705. When the adjusting threaded rod 705 rotates, it can drive the lifting of the welding hand 710, the welding gun 711 and the wire reel 712, thereby realizing the welding of the cargo box areas at different heights;

[0076] S6. Welding. During welding, first, according to the rotating assembly 500, move the welding gun 711 to the position where welding is required. After moving to the specified position, adjust the pitch angle of the welding gun 712 through the welding hand 710. At this time, welding can be carried out through the welding gun 711. During welding, by moving the trolley 100 on the main rail assembly, the switching assembly and the slave rail assembly 400, the welding of the cargo box can be completed.
