Description

Technical Field

[0001] This application relates to the field of welding equipment technology, and more specifically to a self-cleaning welding mobile device for internal welding. 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 specialized internal welding mobile devices.

[0003] A search reveals that existing technologies, such as patent CN201520304217.1, disclose a U-rib welding device, comprising: a moving platform capable of entering the interior of the U-rib to be welded; a welding mechanism disposed on the moving platform for welding the corner joints of the U-rib from the interior; and a driving mechanism driving the moving platform to move within the U-rib. This U-rib welding device can weld the corner joints of the U-rib from the interior, thereby improving the structural strength of the welded U-rib unit; simultaneously, it can reduce weld defects within the U-rib, thus improving the fatigue strength of the U-rib unit. However, the above-mentioned U-rib welding device also has the following drawbacks in practical applications:

[0004] Firstly, the mobile platform has moving wheels on the underside and limit wheels on both sides to enable the platform to move and position within the U-rib. However, when the mobile platform enters the U-rib, impurities such as particles, stains, and dust inside the U-rib can affect the movement of the moving wheels, making it difficult for the mobile platform to move smoothly along the predetermined route within the U-rib, which can adversely affect the continuous and stable welding process.

[0005] Secondly, during the actual welding process, a large number of spattered metal particles are generated. Once these metal particles adhere to the surface of the wheels, they will seriously hinder the stable rolling of the moving wheels. Since the head of the welding torch of the welding mechanism is located at the front end of the moving platform, there will be metal particles in front of the moving platform after welding. This makes it impossible for the moving platform to move forward to the next welding point to run stably. In fact, the metal particles may even adhere to the surface of the moving wheels, causing the moving platform to be unstable. When welding for the next time, it will be difficult for the welding torch to accurately aim at the corner joint of the U-rib. Even if there is a corner joint tracking mechanism, image acquisition device and welding torch controller, the basic moving platform is unstable, and these mechanisms cannot play their full role. Ultimately, it is difficult to guarantee the welding accuracy and quality problems such as uneven weld and insufficient welding strength are likely to occur. Utility Model Content

[0057] like Figure 1 - Figure 8 As shown, the self-cleaning welding mobile device for internal welding described in this application includes a moving component 10, a driving component, a cleaning component 20 disposed on the moving component, and at least two sets of welding guide components 30.

[0058] The cleaning component 20 is disposed at one end of the moving component 10;

[0059] Two sets of welding guide components 30 are disposed opposite to each other on the moving component 10. The two sets of welding guide components 30 are close to the two sides of the moving component 10, and the welding end of the welding guide component 30 extends toward the end of the moving component 10 away from the cleaning component 20.

[0060] The moving component 10 has one end equipped with the cleaning component 20 as its front end and the other end as its rear end. The moving component 10 moves forward or backward in the horizontal direction via a drive component; that is, when the moving component 10 enters the interior of the workpiece 60 to be welded, the front end of the moving component 10 equipped with the cleaning component 20 enters first. Figure 7 and Figure 8 The figures shown are a front view and a rear view of the movable component 10 inside the workpiece 60 to be welded.

[0061] By placing the cleaning component 20 at the front end of the moving component 10, particles, stains, dust, and other impurities on the path can be removed in advance during the movement of the moving component 10 into the workpiece 60 to be welded. This prevents impurities from affecting the movement of the moving component 10, allowing it to move smoothly along a predetermined route and ensuring the continuous and stable welding of subsequent components. Furthermore, the welding end of the welding guide component 30 extends towards the end of the moving component 10 away from the cleaning component 20, meaning the welding end is located at the rear end of the moving component 10. This ensures that metal particles splashed during welding fall onto the rear end of the moving component 10, preventing the moving component 10 from being affected by metal particles when it moves forward to the next welding point. It also reduces the possibility of metal particles falling onto the self-cleaning welding moving device and affecting subsequent welding.

[0062] Furthermore, in this embodiment, the cleaning assembly 20 includes a cleaning scraper mechanism 201 and a pressure spring plate 202;

[0063] One end of the pressure spring plate 202 is connected to the moving component 10, and the other end is connected to the sweeping mechanism 201;

[0064] The sweeping mechanism 201 is slidably connected to the front end of the moving component 10, and the sweeping mechanism 201 moves upward or downward in the vertical direction on the moving component 10 by the elastic force of the pressure spring plate 202; that is, the pressure spring plate 202 has an elastic force downward in the vertical direction. When the sweeping mechanism 201 is subjected to an external force upward in the vertical direction, the sweeping mechanism 201 presses against the pressure spring plate 202, causing the sweeping mechanism 201 to move upward in the vertical direction. When no external force is applied to the sweeping mechanism 201, the sweeping mechanism 201 moves downward in the vertical direction by the elastic force of the pressure spring plate 202.

[0065] Furthermore, in this embodiment, the sweeping mechanism 201 includes a sweeping plate 2011 and a sweeping brush 2012 connected to each other, and the sweeping brush 2012 is connected to the lower end of the sweeping plate 2011.

[0066] The cleaning plate 2011 is slidably connected to the front end of the moving component 10, and a sliding hole is provided at the sliding connection between the cleaning plate 2011 and the moving component 10.

[0067] A limiting element is provided through the sliding hole, and the sliding hole and the limiting element are in clearance fit; that is, the inner surface of the sliding hole does not contact the limiting element, that is, there is a gap between the inner surface of the sliding hole and the limiting element, so that when the cleaning scraper mechanism 201 moves upward or downward in the vertical direction, the limiting element slides upward or downward relative to the cleaning plate 2011 in the vertical direction along the sliding hole; the limiting element can be a screw;

[0068] One end of the limiting member abuts against the surface of the sweeping plate 2011, and the other end is provided with a sliding hole to connect with the moving component 10, so as to restrict the movement of the sweeping scraper mechanism 201 in the horizontal direction; that is, the sweeping scraper mechanism 201 can only move in the vertical direction, and restricting the movement of the sweeping scraper mechanism 201 in the horizontal direction can prevent the sweeping scraper mechanism 201 from detaching from the moving component 10 during use.

[0069] Furthermore, in this embodiment, each welding guide assembly 30 includes a T-shaped support column 301, a wire feeding mechanism 302, a welding mechanism 303, and a guide mechanism 304.

[0070] The lower end of the T-shaped support column 301 is connected to the movable component 10, and the two ends of the T-shaped support column 301 extend to the front end and rear end of the movable component 10, respectively.

[0071] The wire feeding mechanism 302 and the welding mechanism 303 are respectively connected to the two ends of the T-shaped support column 301, with the wire feeding mechanism 302 close to the front end of the moving component 10 and the welding mechanism 303 close to the rear end of the moving component 10.

[0072] The wire feeding mechanism 302 is connected above the T-shaped support column 301.

[0073] Furthermore, in this embodiment, the welding mechanism 303 includes a welding bracket 3031 and a welding torch 3032;

[0074] One end of the welding bracket 3031 is connected to the T-shaped support column 301, and the other end of the welding bracket 3031 is connected to one end of the welding torch 3032. The welding end of the welding torch 3032 extends away from the T-shaped support column 301, so that the welding end of the welding torch 3032 forms a certain distance from the rear end of the moving component 10. The specific distance can be adjusted according to the actual situation so that the welded metal particles can fall to the rear end of the moving component 10.

[0075] The welding bracket 3031 can adjust the angle and position of the welding torch 3032, so that the welding end of the welding torch 3032 can be welded to different positions.

[0076] Furthermore, in this embodiment, the guide mechanism 304 includes a support plate 3041, a first rotating plate 3042, a second rotating plate 3043, a first guide ball 3044, and a second guide ball 3045;

[0077] The middle part of the support plate 3041 is connected to the T-shaped support column 301 through the connector 50, and the two ends of the support plate 3041 extend to the front end and rear end of the moving component 10 respectively; the connector 50 is a connecting rod, one end of the connecting rod is connected to the middle part of the lower surface of the support plate 3041, and the other end of the connecting rod is connected to the upper surface of the T-shaped support column 301.

[0078] One end of the first rotating plate 3042 and one end of the second rotating plate 3043 are respectively rotatably connected to the two ends of the support plate 3041. The first rotating plate 3042 is close to the front end of the moving component 10, and the second rotating plate 3043 is close to the rear end of the moving component 10. Both the first rotating plate 3042 and the second rotating plate 3043 rotate horizontally around the support plate 3041.

[0079] The end of the first rotating plate 3042 away from the support plate 3041 is rotatably connected to the first guide ball 3044, and the end of the second rotating plate 3043 away from the support plate 3041 is rotatably connected to the second guide ball 3045.

[0080] Because it has two sets of welding guide components 30, that is, two sets of guide mechanisms 304, which are respectively close to the two sides of the moving component 10, when entering the interior of the workpiece 60 to be welded, the first guide ball 3044 and the second guide ball 3045 of the same set are used to contact the side of the interior of the workpiece 60 to be welded. The two sets of guide mechanisms 304 respectively contact the two side of the interior of the workpiece 60 to be welded. Depending on the width of the interior of the workpiece 60 to be welded, the first rotating plate 3042 and the second rotating plate 3043 can rotate around the support plate 3041 in the horizontal direction away from the side of the interior of the workpiece 60 to be welded.

[0081] Furthermore, in this embodiment, the guide mechanism 304 also includes a return force 3046, a first rotary bearing 3047, and a second rotary bearing 3048;

[0082] Both the rotational connection between the first rotating plate 3042 and the support plate 3041, and the rotational connection between the second rotating plate 3043 and the support plate 3041, are equipped with return devices 3046. Both the first rotating plate 3042 and the second rotating plate 3043 can rotate back to their initial positions via the rebound force of the return devices 3046. Because the return devices 3046 have a rebound force, both the first rotating plate 3042 and the second rotating plate 3043 tend to move towards their initial positions. That is, when entering the interior of the workpiece 60 to be welded, the first rotating plate 3042 and the second rotating plate 3043... The movable plate 3043 rotates horizontally away from the inner side of the workpiece 60 to be welded around the support plate 3041, while the first rotating plate 3042 and the second rotating plate 3043 move towards the inner side of the workpiece 60 to be welded by the rebound force of the return device 3046, so that the first guide ball 3044 and the second guide ball 3045 abut against the inner side of the workpiece 60 to be welded. The two sets of first guide balls 3044 and second guide balls 3045 abut against the two sides inside the workpiece 60 to be welded, so as to guide the movement of the moving component 10.

[0083] The first rotary bearing 3047 is disposed at the rotary connection between the first rotary plate 3042 and the first guide ball 3044;

[0084] The second rotating bearing 3048 is disposed at the rotating connection between the second rotating plate 3043 and the second guide ball 3045.

[0085] Furthermore, in this embodiment, the moving component 10 includes a base 101, a moving wheel 102, and a handle 103;

[0086] Multiple movable wheels 102 are rotatably connected to both sides of the base 101, and movable wheels 102 are rotatably connected to both sides of the base 101 near the front end and near the rear end; that is, two movable wheels 102 are provided at the front end of both sides of the base 101, and two movable wheels 102 are provided at the rear end of both sides of the base 101.

[0087] A handle 103 is located at the front end of the base 101; by applying external force to the handle 103, the base 101 can be pulled or pushed, causing the base 101 to move in the horizontal direction.

[0088] Furthermore, in this embodiment, the cleaning plate 2011 is made of rubber material; the cleaning plate 2011 made of rubber material allows the two ends of the cleaning plate 2011 to undergo elastic deformation when entering channels of different widths, thereby enabling it to enter channels of different widths.

[0089] The cleaning brush 2012 is made of steel wire. The cleaning brush 2012 made of steel wire can clean up some larger particles, thereby avoiding the situation where the moving component 10 encounters large particles and becomes unstable during movement.

[0090] Furthermore, in this embodiment, the driving component includes a drive motor and a wire feeding motor 40;

[0091] The drive motor is installed inside the base 101, and the output end of the drive motor is rotatably connected to the moving wheel 102; the drive motor drives the moving wheel 102 to rotate, thereby driving the base 101 to move forward or backward in the horizontal direction.

[0092] The wire feeding motor 40 is located at one end of the T-shaped support column 301 near the wire feeding mechanism 302, and the output end of the wire feeding motor 40 is rotatably connected to the wire feeding mechanism 302; the wire feeding mechanism 302 has welding wire, and the wire feeding mechanism 302 is driven by the wire feeding motor 40 to feed the welding wire to the welding mechanism 303.

[0093] The following will, in conjunction with the above content, fully describe the working process of a self-cleaning welding mobile device for internal welding in this embodiment.

[0094] First, the drive motor drives the moving wheel 102 to rotate, causing the moving wheel 102 to move the base 101 into the interior of the workpiece 60 to be welded. The front end of the base 101 enters the interior of the workpiece 60 first, and the cleaning component 20 at the front end of the base 101 can remove particles, stains, dust and other impurities on the internal path of the workpiece 60 to be welded, so as to prevent impurities from affecting the movement of the moving component 10 and to enable the moving component 10 to move smoothly along the predetermined route. In addition, the two sets of guide mechanisms 304 can guide the movement of the moving component 10 from both sides that abut against the interior of the workpiece 60 to be welded, so as to prevent the movement of the moving component 10 from deviating inside the workpiece 60.

[0095] Next, after the base 101 moves to the position to be welded, welding is performed by the welding mechanism 303 set on the moving component 10. Since the moving component 10 is provided with two sets of welding mechanisms 303 arranged opposite to each other, and the two sets of welding mechanisms 303 are close to the two sides of the moving component 10 respectively, the two sides inside the workpiece 60 to be welded can be welded at the same time. The welding mechanism 303 includes a welding bracket 3031 and a welding torch 3032. The angle of the welding torch 3032 can be adjusted by the welding bracket 3031, so that the welding end of the welding torch 3032 can weld to different positions.

[0096] Then, the wire feeding motor 40 drives the wire feeding mechanism 302 to feed the welding wire to the welding mechanism 303 for welding. Since the welding end of the welding gun 3032 is a certain distance from the rear end of the moving component 10, the metal particles formed by welding fall to the rear end of the moving component 10, reducing the situation where the metal particles fall onto the self-cleaning welding moving device and affect subsequent welding.

[0097] Finally, after welding is completed, the component moves forward along the interior of the workpiece 60 to the next welding point. Since the metal particles formed by welding all fall to the rear end of the moving component 10, the moving component 10 will not be affected by the metal particles when it moves forward to the next welding point. This reduces the situation where metal particles are adsorbed onto the moving wheel 102 and affect the stability of the movement.

[0098] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application.

[0099] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this application.
