Description

Technical Field

[0001] The present invention relates to the technical field of weathering steel welding quality detection, and specifically provides a quality detection device for weathering steel welding. Background Art

[0002] Weathering steel, namely atmospheric corrosion-resistant steel, is a series of low-alloy steels between ordinary steel and stainless steel. Weathering steel is made by adding a small amount of corrosion-resistant elements such as copper and nickel to plain carbon steel, and has the characteristics of high strength, toughness, plasticity, formability, welding and cutting, abrasion resistance, high temperature resistance, fatigue resistance, etc. of high-quality steel; the weather resistance is 2-8 times that of plain carbon steel, and the painting property is 1.5-10 times that of plain carbon steel. At the same time, it has rust resistance, which can extend the service life of components, reduce thickness and consumption, save labor and energy. Weathering steel is mainly used for steel structures such as railways, vehicles, bridges, towers, photovoltaic, and high-speed projects that are exposed to the atmosphere for a long time.

[0003] When connecting weathering steel, welding is usually used for fixation. In the prior art, the human eye is generally used to judge whether the welding quality of the welded product is qualified. However, the judgment by the human eye has a very high probability of error because the internal welding situation cannot be observed, and the efficiency is also very low. Some mechanical detection devices are large in size and difficult to carry around to detect the quality of the welded joints of weathering steel installed on some construction sites, which greatly reduces the work efficiency.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1

[0030] See also Figures 1 - 5, a quality inspection device for weathering steel welding shown in the figure includes a fixed rod 1, a measuring device 5, an adjusting device 6 and a detection mechanism 7. One end of the fixed rod 1 is rotatably connected to a handle 2, and a rotating rod 3 is fixedly connected to the handle 2. The rotating rod 3 penetrates the fixed rod 1 and is rotatably connected to the fixed rod 1. One end of the rotating rod 3 is fixedly connected to a rotating block 4. The measuring device 5 is provided with two groups and is respectively installed on the rotating block 4 and the fixed rod 1, and is used to fix and tap the weathering steel parts on both sides of the weathering steel welding part, and feedback the welding quality of the middle welding part through the vibration frequency of the other side. The adjusting device 6 is installed on the handle 2, and is used to adjust the angle between the two groups of measuring devices 5 and measure and fix the angle. The detection mechanism 7 is installed between the two groups of measuring devices 5, and is used to always face the welding position in the middle of the two groups of measuring devices 5 when the measuring device 5 rotates, and to detect the flatness of the welding part in linkage when the measuring device 5 is tapped for detection.

[0031] See also Figures 1 - 9 The measuring device 5 shown in the figure includes two groups of device boxes 8 fixedly installed on the rotating block 4 and the fixed rod 1 respectively. Two groups of device grooves 9 are opened on the device box 8. A sliding tube 10 is slidably connected in the device groove 9.

[0033] Example 2

[0034] See also Figures 4 - 11Embodiment 2 is described. This embodiment further describes Embodiment 1. The knocking member 14 shown in the figure includes a first spring 15 fixedly installed in the sliding tube 10. A knocking rod 16 is slidably connected in the sliding tube 10. A knocking head 17 is fixedly connected at one end of the knocking rod 16. The knocking head 17 is made of rubber material. A driving member 18 is provided on the device box 8 for driving the two groups of knocking rods 16 to slide back and forth continuously in the sliding tube 10, and the operating state is not affected by the position of the sliding tube 10.

[0035] See also Figures 6 - 11 The driving member 18 shown in the figure includes a rotating ring 19, and the side of the rotating ring 19 is provided with a corrugated groove 20 which is slidably connected to one end of the two groups of knocking rods 16 respectively, and a driving frame 21 is fixedly connected to the rotating ring 19, and a gear column 22 is fixedly connected to the side of the driving frame 21, and a driving motor 23 is fixedly connected in the device box 8, and the output end of the driving motor 23 is fixedly connected to a first gear 24 meshing with the gear column 22, and a fixing ring 25 which is fixedly connected to one end of the two groups of sliding tubes 10 is rotatably connected to the rotating ring 19, and a first tension spring 26 which is fixedly connected to the device box 8 is fixedly connected to the fixing ring 25, and an indicator light 27 which is used to display whether the vibration received by the vibration sensor 12 meets the standard vibration frequency of the weathering steel welding strength is fixedly connected to the side of the rotating ring 19.

[0036] See also Figures 6 - 11 The clamping member 13 shown in the figure includes two groups of clamping plates 28 respectively located on both sides of the device box 8, two groups of toggle rods 29 are fixedly connected to the two groups of clamping plates 28, a rotating shaft 30 is fixedly connected to the toggle rod 29, a bracket 31 rotatably connected to the rotating shaft 30 is fixedly connected to the device box 8, a clockwork spring 32 fixedly connected to the side of the device box 8 is fixedly connected to the rotating shaft 30, one end of the toggle rod 29 is in conflict with the sliding block 11, and rubber pads 33 are fixedly connected to the sides of the two groups of clamping plates 28.

[0037] In this embodiment, the driving motor 23 model is preferably LD60 micro motor, and one end of the sliding tube 10 is pressed against the surface of the weathering steel. The sliding tube 10 drives the sliding block 11 to slide in the device groove 9, and the sliding block 11 pushes one end of the toggle rod 29, so that the toggle rod 29 rotates around the rotating shaft 30. While the clockwork spring 32 is compressed, the rubber pads 33 on both sides clamp the two sides of the weathering steel to complete the fixation. Starting the driving motor 23 can drive the first gear 24 to rotate, thereby driving the gear column 22 to rotate. The gear column 22 drives the driving frame 21 and the rotating ring 19 to rotate, so that the corrugated groove 20 continuously pushes one end of the knocking rod 16. The knocking rod 16 slides in the sliding tube 10 and compresses the first spring 15, so that the knocking head 17 continuously extends out to hit the surface of the weathering steel. The vibration intensity can be measured by the vibration sensor 12 on the device box 8 on the other side, and the detection structure is displayed by the indicator light 27 (such as red represents unqualified and green represents qualified).

[0038] It is worth noting that when the sliding tube 10 contacts the weathering steel, it will push the fixing ring 25 to slide. When the first tension spring 26 is stretched, the rotating ring 19 drives the gear column 22 to slide. At this time, the corrugated groove 20 is always in contact with one end of the knocking rod 16. At the same time, the movement of the gear column 22 does not affect the meshing transmission between it and the first gear 24. The rubber knocking head 17 and the rubber pad 33 can effectively prevent damage to the surface of the weathering steel.

[0039] Example 3

[0040] See also Figures 2 - 7 Embodiment 3 is described. This embodiment further describes Embodiment 1. The detection mechanism 7 shown in the figure includes an arc-shaped guide rail 34. The upper and lower ends of both sides of the arc-shaped guide rail 34 are fixedly connected with elastic ropes 35 respectively fixedly connected to the sides of the device boxes 8 on both sides. A laser probe 36 for detecting the flatness of the welding part is slidably connected to the arc-shaped guide rail 34. The laser probe 36 is provided with a linkage part 37 for linking the laser probe 36 to reciprocate in the arc-shaped guide rail 34 when the rotating rings 19 on both sides rotate.

[0041] See also Figures 6 - 7 The linkage part 37 shown in the figure includes two groups of pull ropes 38 fixedly installed on both sides of the laser probe 36, and the upper and lower ends of the arc guide rail 34 are fixedly connected with guide rings 39. The side of the rotating ring 19 is fixedly connected with a pull rod 40. The two groups of pull ropes 38 are fixedly connected to the two groups of pull rods 40, and the two groups of pull ropes 38 are slidably connected to the inner walls of the two groups of guide rings 39.

[0042] See also Figures 4 - 5 The adjusting device 6 shown in the figure includes a scale ring 41 fixedly mounted on the handle 2, the scale ring 41 is rotatably connected to the fixed rod 1, and the fixed rod 1 is provided with a limiting member 42 for limiting the scale ring 41.

[0043] See also Figures 4 - 5 The limiting member 42 shown in the figure includes a toggle block 43, a sliding groove 44 is provided on the fixed rod 1, the toggle block 43 is slidably connected to the sliding groove 44, a plug-in rod 45 is fixedly connected to the toggle block 43, a plurality of groups of plug-in grooves 46 with equal spacing are provided on the side of the scale ring 41, and a second tension spring 47 fixedly connected to the sliding groove 44 is fixedly connected to the side of the toggle block 43.

[0044] In this embodiment, by pushing the toggle block 43 so that the plug-in rod 45 is released from the plug-in slot 46, the handle 2 can be turned to drive the device box 8 on one side to rotate. The angle between the two groups of device boxes 8 can be judged by the degree on the scale ring 41, so as to determine whether the welding angles of the two groups of welded weathering steels are consistent. When the angle is adjusted appropriately, the toggle block 43 is released, and the second tension spring 47 pulls the toggle block 43 so that the plug-in rod 45 is inserted into the plug-in slot 46 to complete the fixation. Since the tension of the elastic ropes 35 on both sides on the arc guide rail 34 is the same, no matter how the device boxes 8 on both sides are rotated to any desired angle, the arc guide rail 34 can be located on the bisector of the angle between the two groups of device boxes 8. At the same time, since the welding parts of the weathering steel are mostly located on the bisector of the two groups of weathering steel potassium capsules, the moving scanning direction of the laser probe 36 is more in line with the welding position, and the rotating ring 19 is rotated. When rotating, the pull rod 40 will be driven to continuously pull the pull rope 38. The pull rope 38 has a certain elasticity, and when one group of rotating rings 19 rotates, the rotating rings 19 of the other group are in a stationary state. At the same time, the pull rod 40 on the rotating ring 19 in the stationary state is in a position where the pull rope 38 is pulled to the maximum limit, so that when the rotating ring 19 in the rotating state rotates, the pull rope 38 can be driven to continuously pull the laser probe 36 back and forth between the upper and lower ends of the arc guide rail 34, so that the laser probe 36 can more comprehensively scan the flatness of the welding part and transmit it to the mobile phone through some APP or display the scanning results by installing a display screen (not shown) on the fixed rod 1. The spacing of the plug-in slots 46 can be set smaller. When the plug-in rod 45 is inserted into the adjacent plug-in slots 46, the rotation angle of the handle 2 is about 1 to 5° (the specific degree can be determined according to the maximum measurement error range value).
