Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a self-clearing welding mobile device suitable for field welding. Background Technology

[0002] In the welding production of large bridges, pressure vessels, oil and gas pipelines, many large workpieces are difficult to transport to the factory for welding, thus requiring welding work to be carried out in the field. Due to direct contact with the outside environment, the field welding process is likely to be affected by adverse weather conditions such as wind, sand, rain, snow, and hail. For example, wind and sand can bring sand and dust into the welding area, severely impacting welding accuracy, weld microstructure, and mechanical properties. Faced with this practical problem, in actual production, the only solution is to erect temporary sheds or curtains to prevent contamination from wind, sand, rain, snow, and hail, but this increases the investment in welding operations and reduces production efficiency.

[0033] like Figures 1-4As shown in the figure, the self-clearing welding mobile device for field welding disclosed in this embodiment includes a mobile trolley 1, a welding assembly 2, and a clearing assembly 3. The welding assembly 2 is mounted on the mobile trolley 1 and has two welding ends, corresponding to the left and right sides of the mobile trolley 1, respectively. The clearing assembly 3 includes a front clearing mechanism 31, a middle clearing mechanism 32, and a rear clearing mechanism 33, located at the front, side, and rear ends of the mobile trolley 1. The middle clearing mechanism 32 is located near the welding ends and is used to remove spattered metal particles generated after welding.

[0034] In practical use, the mobile trolley 1 moves to the designated position, the front obstacle removal mechanism 31 clears the obstacles on the path of the mobile trolley 1 and the welding parts of the workpiece to be welded, and then the welding assembly 2 welds the workpiece to be welded. After the welding is completed, the mobile trolley 1 moves to the next area to be welded. During this movement, the middle obstacle removal mechanism 32 cleans up the spattered metal particles generated during the welding process, and the rear obstacle removal mechanism 33 further cleans the welding area of ​​the workpiece to prepare for the subsequent weld inspection operation.

[0035] Specifically, please refer to Figure 2 The mobile trolley 1 includes a chassis 11, four symmetrically arranged wheels 12 on the sides of the chassis 11, a handle 13 at the front of the chassis 11, and an electrical control box 14 mounted on the chassis 11. The chassis 11 is designed for both automatic and manual operation. The electrical control equipment is housed in the electrical control box 14 at the rear of the chassis 11. The handle 13 at the front of the chassis 11 allows the mobile trolley 1 to be manually pulled in manual mode or when the platform loses power. Four mounting holes are symmetrically arranged at the four corners of the chassis 11 for mounting front / rear obstacle removal mechanisms.

[0036] Preferably, the welding assembly 2 includes a wire spool 21, two wire feeding wheel sets 22, a wire feeding motor 23, a mounting base 24, and two welding torches 25. The wire spool 21 is located on the top of the mobile carriage 1, and welding wire is wound on the wire spool 21. The two wire feeding wheel sets 22 are positioned opposite each other on the top of the mobile carriage 1, and the welding wire is wound from the wire spool 21 onto the wire feeding wheel sets 22. The wire feeding motor 23 is located on the wire feeding wheel sets 22 and drives the rollers 221 on the wire feeding wheel sets 22 to rotate, thereby transmitting the welding wire. The mounting base 24 is located on the mobile carriage 1. The two welding torches 25 are symmetrically positioned on the top of the mobile carriage 1, and the welding wire on the two wire feeding wheel sets 22 is respectively connected to the two welding torches 25, with each welding torch 25 corresponding to a different welding end. In this embodiment, the welding torch 25 is fixedly positioned on the mounting base 24 by welding torch fastening screws. The welding wire coil is stored in the welding wire spool 21 for later use. The wire feeding wheel assembly 22 includes a support frame 222 set on the moving trolley 1. The rollers 221 are rotatably set on the support frame 222. The rollers 221 are divided into upper and lower layers. There are three rollers in the upper layer and two rollers in the lower layer. The wire feeding motor 23 drives the rollers 221 located in the lower layer near the welding torch 25 to rotate, thereby pulling the welding wire out of the welding wire spool 21. The front end of the welding wire is fed into the welding torch 25. The control components of the wire feeding motor 23 are placed in the electrical control box.

[0037] This embodiment also includes two camera probes 5 disposed on the left and right sides of the mobile trolley 1. Specifically, the two camera probes 5 are disposed on the left and right sides of the chassis 11 to monitor whether the moving wheels 12 in front of the mobile trolley 1 roll smoothly, and can monitor and detect the subtle changes in the moving trajectory when the moving wheels 12 press on foreign objects.

[0038] In this embodiment, the front obstacle clearing mechanism 31 and the rear obstacle clearing mechanism 33 have the same structure, both including two obstacle clearing parts symmetrically arranged at the front or rear corners of the mobile trolley 1. The obstacle clearing part 30 includes a support arm 301 rotatably connected to one corner of the front or rear of the mobile trolley 1, a brush handle 302 disposed at the end of the support arm 301 away from the mobile trolley 1, and first brush bristles 303 disposed on the left and right sides, the left and right corners of the bottom, and the bottom edge of the brush handle 302. In this embodiment, the brush handle 302 is a rectangular plate, and the two bottom corners of the rectangular plate are chamfered to install the first brush bristles 303 at the bottom left and right corners. Its material is an alloy material (stainless steel or aluminum alloy). Specifically, the first bristles 303 on the left and right sides and bottom edge of the brush handle 302 on the front clearing mechanism 31 are all soft bristles, which can be nylon bristles. They are used to remove sand or dust in front of the welding mobile trolley 1 first, so as to avoid causing hidden dangers to the normal operation of the mobile trolley 1. The first bristles 303 at the bottom left and right corners of the brush handle 302 on the front clearing mechanism 31 are hard bristles, which can be steel wire bristles. They can clean the dirt and dust in the area to be welded and the harder oxide film on the base material, so as to avoid the weld inclusion defects caused by foreign objects entering the molten pool, which would reduce the mechanical properties of the joint weld.

[0039] Preferably, the first bristles 303 on the left and right sides, the left and right corners of the bottom, and the bottom edge of the brush handle 302 on the rear clearing mechanism 33 are all made of hard bristles, i.e. steel wire bristles. This is because the spattered metal particles generated after welding are relatively hard and may be weakly welded to the surface of the workpiece. Therefore, the rigidity of the brush must be increased to ensure that these spattered metal particles can fall off the surface of the workpiece, thereby preparing for the subsequent weld inspection work.

[0040] Preferably, the support arm 301 includes a swing arm 3011 rotatably connected to one corner of the front end of the mobile trolley 1. A mounting handle 3021 is provided on the side of the brush handle 302, with a mounting hole on the mounting handle 3021. A spring 3012 is provided at the top of the mounting handle 3021. A through hole is provided at the end of the swing arm 3011 away from the mobile trolley 1. The spring 3012, the mounting hole, and the through hole are concentrically arranged. The spring 3012, the swing arm 3011, and the mounting handle 3021 are fixed together from top to bottom by swing arm fastening screws 3013 passing through the through hole, the spring 3012, and the mounting hole in sequence. The spring 3012 provides downward pressure to the brush handle 302, ensuring that the brush handle 302 remains firmly pressed against the surface of the workpiece to be cleaned, thus improving the cleaning effect and success rate.

[0041] Preferably, the intermediate obstacle removal mechanism 32 includes two intermediate obstacle removal sections symmetrically arranged on the left and right sides of the mobile trolley 1. Each intermediate obstacle removal section includes an intermediate brush handle 321 disposed on the side of the mobile trolley 1 and second brush bristles 322 disposed on the side, bottom corner, and bottom edge of the intermediate brush handle 321. The second brush bristles 322 on the side, bottom corner, and bottom edge of the intermediate brush handle 321 are all hard bristles. The intermediate brush handle 321 is designed in an L-shape to fit the side profile of the chassis 11. The edges of the component brush handle 321 are all made of wire brush. The intermediate brush handle 321 is also made of alloy material (stainless steel or aluminum alloy). Considering that a large number of spattered metal particles will be generated after welding, the wire brush has greater rigidity and can easily peel off the spattered metal particles that are weakly welded to the surface of the workpiece. At the same time, when high-temperature metal particles encounter the wire brush, they will not damage the integrity of the brush structure, whereas with nylon brushes, hot metal particles splashing onto the nylon brush will cause the brush to melt and deform.

[0042] This embodiment also includes two sets of positioning components 4 disposed on the left and right sides of the mobile carriage 1. Each set of positioning components 4 has two components, and the welding part is located between the two positioning components 4 in the same set. The positioning component 4 includes a telescopic arm 41 slidably connected to the mobile carriage 1 and a guide wheel 42 disposed at the end of the telescopic arm 41 away from the mobile carriage 1. Specifically, the middle brush handle 321 is installed on the side of the telescopic arm 41 on the rear side of the chassis 11 near the welding torch 25 and can move with the telescopic arm 41. This design can prevent a large number of metal spatter particles generated during the welding process from splashing onto the working surface of the rear guide wheel 42 and the rear moving wheel 12, effectively ensuring the stable movement of the mobile carriage 1 and the welding accuracy during the welding process. A linear slide rail 101 is designed on the mobile chassis 11 and between the front and rear moving wheels 12, which can precisely install and fix the telescopic arm 41. The telescopic arm 41 is provided with a groove adapted to the linear slide rail 101. The telescopic arm 41 and the guide wheel 42 can move one-dimensionally along the linear slide rail 101 to meet the welding positioning requirements of workpieces of different sizes.

[0043] In summary, the self-clearing welding mobile device for field welding in this embodiment, through the cooperation of the front clearing mechanism 31, the middle clearing mechanism 32 and the rear clearing mechanism 33, clears obstacles and welding waste while welding in the field, which improves welding efficiency and quality, reduces the time and labor intensity of manual clearing of obstacles and waste, and is highly adaptable to cope with different terrains and welding environments in the field.
