Description

Technical Field

[0001] This application relates to the field of welding equipment technology, and more specifically to an obstacle-avoiding magnetic wheel assembly for an internal welding mobile platform. Background Technology

[0002] Internal welding is a common practical problem encountered in welding production, especially in the welding of large bridges, pressure vessels, oil and gas pipelines, etc. Since it is difficult for construction personnel to enter the interior of the structure, internal welding is often completed using a dedicated internal welding mobile platform.

[0003] These welding platforms primarily utilize permanent magnet wheels with strong magnetic force for movement. However, the welding process inevitably generates a large amount of spatter. This molten metal, splashed from the weld pool, cools rapidly upon contact with air, forming irregular metal particles. These particles severely hinder the smooth and precise rolling of the magnetic wheels on the internal welding platform, leading to a significant decrease in internal welding quality and precision. Currently, it is difficult to achieve timely and rapid cleaning of spatter particles during the internal welding process manually, and no dedicated automated cleaning equipment has been implemented.

[0044] 50 - Internal welding mobile platform. Detailed Implementation

[0045] like Figure 1 - Figure 8 As shown, the obstacle-avoiding magnetic wheel set for an internal welding mobile platform described in this application is applied to an internal welding mobile platform 50 and includes:

[0046] Example 1

[0047] The axle 10 includes a fastening section 101, a wheel assembly mounting section 102, a wheel stop flange section 103, and a platform mounting section 104 distributed sequentially along the axial direction, and the platform mounting section 104 is rotatably connected to the internal welding moving platform 50; the fastening section 101, the wheel assembly mounting section 102, and the wheel stop flange section 103 extend in a direction away from the internal welding moving platform 50;

[0048] A plurality of wheel disks 20 are disposed in the wheel assembly mounting section 102, and the wheel disks 20 are made of magnetic material; specifically, the magnetic material of the wheel disks 20 is artificial magnet steel. During use, the surface of the wheel disks 20 can adsorb some of the splashed metal particles. This adsorption helps to reduce the accumulation of metal particles in the welding area, thereby reducing the impact of metal particles on welding quality and precision to a certain extent, and reducing the impact of metal particles generated during welding on the movement of the internal welding moving platform 50; the outer edge of the wheel disks 20 has an arc-shaped structure.

[0049] At least one limiting member 30 is disposed on the wheel assembly mounting section 102, and the limiting member 30 is located between two adjacent wheel discs 20; specifically, the limiting member 30 is a limiting ring, which is circular and has a through hole in the middle that is adapted to the outer surface of the wheel assembly mounting section 102.

[0050] Fastener 40 is connected to fastening section 101. Fastener 40 and wheel flange section 103 abut against the wheel disc 20 from both axial ends of wheel assembly mounting section 102 to restrict the axial movement of wheel disc 20. Specifically, fastener 40 is a nut. Fastener 40 is connected to fastening section 101 so that fastener 40 abuts against one end of wheel assembly mounting section 102 near fastening section 101. Wheel flange section 103 abuts against one end of wheel assembly mounting section 102 near wheel flange section 103. Thus, fastener 40 and wheel flange section 103 abut against the wheel disc 20 provided on wheel assembly mounting section 102 from both axial ends of wheel assembly mounting section 102 to restrict the axial movement of wheel disc 20.

[0051] The wheel 20, the limiting member 30, and the fastener 40 all rotate synchronously with the wheel axle 10. The wheel axle 10 is rotatably connected to the internal welding moving platform 50. During the movement, the wheel axle 10 rotates, thereby driving the internal welding moving platform 50 to move. Therefore, during the rotation of the wheel axle 10, the wheel 20, the limiting member 30, and the fastener 40 all rotate synchronously with the wheel axle 10.

[0052] Furthermore, in this embodiment, the wheel assembly mounting section 102 is divided into a first wheel disc mounting section, a second wheel disc mounting section, and a third wheel disc mounting section from the end near the fastening section 101 to the end near the wheel stop flange section 103.

[0053] Multiple roulette wheels 20 are arranged at intervals in both the first roulette wheel mounting section and the second roulette wheel mounting section; that is, there is a certain gap between every two roulette wheels 20 in the first roulette wheel mounting section and the second roulette wheel.

[0054] Multiple roulette wheels 20 are arranged adjacent to each other in the third roulette wheel mounting section; that is, the distance between any two roulette wheels 20 in the third roulette wheel mounting section is 0.

[0055] Furthermore, in this embodiment, the shortest surface interval between two adjacent discs 20 on the first disc mounting section is L1, and the shortest surface interval between two adjacent discs 20 on the second disc mounting section is L2, satisfying L1:L2=2:1;

[0056] The thickness of the limiting member 30 along the axial direction is equal to that of L2.

[0057] Furthermore, in this embodiment, two limiting members 30 are provided between every two adjacent discs 20 on the first disc mounting section;

[0058] A limiting element 30 is provided between every two adjacent wheels 20 on the second wheel installation section;

[0059] For MIG welding, the maximum size and number of spatter particles decrease as the distance from the weld seam increases. Therefore, the distance from the weld seam increases sequentially for the first, second, and third disc mounting sections. Two limiting members 30 are installed near the weld seam in the first disc mounting section to increase the distance between adjacent discs 20. This allows larger spatter particles to fall smoothly into the gap between the discs 20 on the first disc mounting section when the obstacle-avoiding magnetic wheel assembly rotates. The second disc mounting section absorbs some of the spatter particles. The adjacent discs on the second disc mounting section... Smaller particles can also fall between the two discs 20. The third disc mounting section is far from the welding position and is set up close. Therefore, the disc 20 on the third disc mounting section can attract some particles through its outer edge. The size of the attracted particles is also smaller than the size of the particles attracted on the first and second disc mounting sections. This ensures that the obstacle-avoiding magnetic wheel set has sufficient support for the internal welding moving platform 50, while allowing the setting of the discs 20 to be selected according to the actual application situation. This avoids splashing particles from hindering the smooth and precise rolling of the obstacle-avoiding magnetic wheel set on the surface of the workpiece to be welded.

[0060] Furthermore, in this embodiment, the axial cross-section of the wheel assembly mounting section 102 is hexagonal;

[0061] Both the wheel disc 20 and the limiting member 30 have hexagonal through holes that are adapted to the wheel assembly mounting section 102. The wheel assembly mounting section 102 passes through the hexagonal through holes of the wheel disc 20 and the limiting member 30, so that both the wheel disc 20 and the limiting member 30 are connected to the wheel assembly mounting section 102.

[0062] Furthermore, in this embodiment, the straight-line distance between the two parallel edges on the axial cross-section of the wheel assembly mounting section 102 is W, the axial cross-sectional diameter of the fastening section 101 is D1, and the axial cross-sectional diameter of the wheel stop flange section 103 is D2, satisfying D1 < W < D2; the optimal choice for the axial cross-sectional diameter D2 of the wheel stop flange section 103 is 4cm, the optimal choice for W is 3cm, and the optimal choice for the axial cross-sectional diameter D1 of the fastening section 101 is 2cm, satisfying D1 < W < D2.

[0063] Furthermore, in this embodiment, the outer surface of the fastening section 101 is provided with threads, and the fastener 40 has a threaded hole adapted to the fastening section 101, and the fastener 40 is threadedly connected to the fastening section 101.

[0064] Furthermore, in this embodiment, the length of the wheel assembly mounting section 102 is 5cm to 15cm; the optimal length of the wheel assembly mounting section 102 is 8cm.

[0065] The diameter of the wheel 20 is 8cm to 15cm, and the axial thickness is 0.5cm to 1.5cm; the optimal diameter of the wheel 20 is 12cm, and the optimal axial thickness is 0.8cm.

[0066] The diameter of the limiting member 30 is 3cm to 6cm, and its axial thickness is 0.2cm to 1.5cm. The axial thickness of the limiting member 30 is equal to L2, i.e., L2 = 0.2cm to 1.5cm, and L1 is twice L2. Therefore, the optimal choice for the diameter of the limiting member 30 is 4cm, and the optimal choice for the axial thickness is 0.8cm. The optimal choice for L2 is L2 = 0.8cm, and the optimal choice for L1 is L1 = 1.6cm.

[0067] Furthermore, in this embodiment, the axle 10 is made of steel; the steel material of the axle 10 is any one of stainless steel, high-strength steel and tool steel, and in order to ensure the rigidity of the axle 10, the axle 10 is manufactured by integral machining.

[0068] The limiting component 30 is made of any one of stainless steel, aluminum alloy, and titanium alloy.

[0069] Fastener 40 is made of stainless steel or cast iron.

[0070] Example 2

[0071] This implementation is the same as that of Example 1, except that multiple discs 20 are arranged at equal intervals on the wheel assembly section 102, and a limiting member 30 is provided between each two adjacent discs 20, forming a structure in which discs 20 and limiting members 30 are alternately arranged; that is, the distance between each two adjacent discs 20 is equal, and there is a limiting member 30 between each two adjacent discs 20.

[0072] For laser welding, the size of the weld pool is significantly smaller than that of arc welding, and the maximum size of the spatter is smaller and the distribution is more uniform. Using the structure in Embodiment 2, the spatter particles, which are smaller than those in arc welding, can smoothly enter the gap of the wheel 20 during the rolling of the obstacle-avoiding magnetic wheel assembly while supporting the internal welding moving platform 50, so as to avoid hindering the forward rolling of the wheel assembly. Moreover, when the wheel 20 touches the spatter particles, the arc-shaped structure of the outer edge of the wheel 20 can also make the spatter particles fall smoothly into the gap of the wheel 20, realizing the rapid obstacle avoidance function of the obstacle-avoiding magnetic wheel assembly.

[0073] like Figure 8 As shown, obstacle-avoiding magnetic wheel sets are respectively installed at the front and rear ends on both sides of the internal welding moving platform 50 to support the internal welding moving platform 50 to perform linear motion.

[0074] In summary, the magnetic wheel 20, during its rolling process, can adsorb some of the splashed metal particles on its surface. This adsorption helps reduce the accumulation of metal particles in the welding area, thereby mitigating their impact on welding quality and precision to some extent. Because the magnetic wheel 20 has adsorption capabilities, the need for manual cleaning of splashed metal particles is reduced, improving work efficiency and reducing additional costs and time associated with cleaning. During internal welding, the magnetic wheel 20 adsorbs metal particles that obstruct movement, enabling the obstacle-avoiding magnetic wheel assembly to roll stably and position precisely, thus improving welding efficiency and quality. This ensures the smooth movement of the internal welding platform 50 within complex structures, providing welders with a stable working platform.
