Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding equipment technology, and in particular to a multi-directional four-wheel welding trolley for pipe welding. Background Technology
[0002] In the process of welding components onto large pipes or plates, operators typically need to manually hold the welding torch. This method is not only difficult to operate, but also gradually reduces welding efficiency due to the continuous welding operation time. To solve this technical problem, four-wheeled welding carriages for pipe welding have been introduced to the market. These welding carriages move via wheels and tracks and are equipped with a transmission mechanism with two linear motion axes, specifically the lateral linear axis of the welding carriage itself and the vertical linear axis of the welding torch adjustment device. Given that pipe welding requires all-position welding, the welding torch's posture needs to be dynamically adjusted in different phases of the pipe. However, the current two-linear-axis solution suffers from insufficient degrees of freedom and limited accessibility; furthermore, most welding carriages use a lead screw as the lateral adjustment mechanism for the welding torch, which not only increases the difficulty of disassembly and assembly but also brings inconvenience to maintenance.

In this embodiment, the support plate 5 is located on the left side of the electrical control cabinet 4 (…). Figure 4 Furthermore, to ensure a reasonable spatial layout, the support plate 5 is set vertically.
[0029] The lateral movement assembly includes two rows of limiting wheels 8 rotatably mounted on one side of the support plate 5, a moving rod 9 slidably disposed between the two rows of limiting wheels 8, a connecting seat 10 fixedly mounted on the end of the moving rod 9 facing the welding torch 3, and a lateral movement mechanism for driving the moving rod 9 to slide horizontally relative to the support plate 5 along its axial direction. Each row of limiting wheels 8 has at least two wheels, and the axle of the limiting wheels 8 is perpendicular to the surface of the support plate 5. The upper and lower sides of the moving rod 9 are provided with sliding grooves that cooperate with the limiting wheels 8, allowing the moving rod 9 to slide smoothly against the support plate 5.

[0036] Working Principle: This utility model discloses a multi-directional four-wheel welding trolley for pipe welding. In use, first loosen the clamping cap 17, and adjust the tilt angle of the welding torch 3 to the optimal state by adjusting the adjusting section 14 of the swing arm 11. Then, tighten the clamping cap 17 again to ensure positioning. The travel motor 33 drives the travel wheels 2 to bring the trolley to the predetermined position. Then, the lateral motor 22 drives the lateral gear 23 to rotate. The lateral gear 23 meshes with the lateral rack 21, pushing the moving rod 9 to slide horizontally along its axis, causing the welding torch 3 to move laterally closer to the workpiece to be welded. Then, the lifting motor 19 drives the lifting gear 20 to rotate, and the lifting gear 20 meshes with the lifting... The lowering rack 18 engages, pushing the lifting plate vertically downward, causing the welding torch 3 to move downward to the initial welding position. Subsequently, the lifting motor 19, the transverse motor 22, and the swing motor 25 cooperate to drive the welding torch 3 to perform multi-directional adjustments in three-dimensional space according to the preset welding program, making the welding carriage more adaptable to the welding needs of complex pipes and plates. When disassembly and maintenance are required, simply rotate the transverse gear 23 to disengage the end of the moving rod 9 away from the connecting seat 10 from the limiting wheel 8, and rotate the lifting gear 20 to disengage the lifting slider 7 upward from the lifting rail 6. Disassembly and assembly are quick, and maintenance is convenient.
[0037] [Example 2] Please refer to Figure 4-5 Since welding generates a large amount of harmful fumes, which is detrimental to the health of operators and makes it difficult to observe the welding effect on site, this embodiment optimizes this aspect.
[0038] The difference from Embodiment 1 is that this embodiment also includes a dust collection assembly. The dust collection assembly includes a dust collection box 26 fixedly mounted on the upper end of the base 1, a dust collection cover 27 fixedly mounted on one side of the welding head of the welding torch 3, a conveying pipe 28 connecting the dust collection cover 27 and the dust collection box 26 with one end extending into the dust collection box 26, a dust collection fan 29 fixedly mounted inside the dust collection box 26 and positioned directly opposite the extension end of the conveying pipe 28, and a filter plate 30 positioned between the dust collection fan 29 and the extension end of the conveying pipe 28, and slidingly engaged with the dust collection box 26; the filter plate slides with the dust collection box 26 for easy replacement after long-term use; the conveying pipe 28 is a flexible hose. A dust collection drawer 31 is provided on the side of the filter plate 30 facing the opening of the conveying pipe 28, and an opening is provided on one side of the dust collection box 26 for easy removal of the dust collection drawer 31. A door 32 is rotatably mounted at the opening, and a handle is fixedly mounted on the door 32.
[0039] During welding, the dust collection fan 29 is started, and negative pressure is generated in the dust collection box 26. The harmful gas particles such as carbon monoxide generated at the welding point are sucked into the dust collection hood 27 and enter the dust collection box 26 through the conveying pipe 28. The solid particles in the dust collection box 26 are filtered by the filter plate 30. After a period of use, the box door 32 can be opened to clean the particle layer remaining on the surface of the filter plate 30 and transport it to the outside of the box through the dust collection drawer 31.
[0040] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
