[0002] Steel structures have advantages such as being lightweight and high-strength, energy-saving and environmentally friendly, and easy to construct, and are widely used in many building fields such as high-rise buildings, super high-rise buildings, stadiums, transportation hubs, and convention centers.

[0003] In practice, situations may arise where the steel structure is not long enough. Therefore, adjacent steel structures are connected using methods such as bolts, welding, and anchor bolts. During welding, the weld metal cannot freely shrink, leading to welding stress and deformation during heating and cooling. To monitor welding deformation and determine weld quality, the welding location needs to be inspected. However, welding deformation varies greatly. Large deformations can be observed visually, but small deformations are difficult to detect after welding. Therefore, existing technologies use portable magnetic particle detectors for easy carrying and inspection. However, these portable magnetic particle detectors require manual addition of magnetic powder-containing suspension liquid, which is inefficient, time-consuming, labor-intensive, and incomplete, thus affecting the detection efficiency and results of the magnetic particle detector.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The diagram shown is a structural schematic of a steel structure welding deformation measurement and detection device for building engineering provided in one embodiment of the present invention, comprising: Steel pipe structure 1; Portable magnetic particle flaw detector 2 is placed on top of steel pipe structure 1; The magnetic flux storage tank 3 is fixedly installed on the right side of the portable magnetic particle flaw detector 2. The first slide groove 7 is symmetrically opened on the side of the portable magnetic particle flaw detector 2, and a traction plate 18 is slidably arranged thereon. A second slider 19 is fixedly installed on the middle of the outer side of the traction plate 18. A high-precision camera 21 is movably mounted on the bottom of the traction plate 18; The spraying structure and the purging structure are symmetrically arranged on the front and rear sides of the portable magnetic particle flaw detector 2, and are movably connected to the second slider 19.

[0020] In this embodiment of the utility model, when a deviation is found in the working position of the spraying structure, the purging structure and the high-precision camera 21, the working position is adjusted accordingly by the traction plate 18 and the spraying structure, the purging structure and the high-precision camera 21 on its side. Thus, the working position of the spraying structure, the purging structure and the high-precision camera 21 can be adjusted without lifting the portable magnetic particle flaw detector 2. By symmetrically arranging spraying and purging structures on the front and rear sides of the portable magnetic particle flaw detector 2, the magnetic suspension fluid can be sprayed onto the welding position of the steel pipe structure 1, and excess magnetic suspension fluid at the welding position of the steel pipe structure 1 can be removed, thereby improving the subsequent detection accuracy. The positions of the spraying structure, purging structure and high-precision camera 21 can be adjusted in real time through the traction plate 18 and the second slider 19 on the first slide groove 7 on the surface of the portable magnetic particle flaw detector 2, so as to improve the spraying, purging and detection accuracy.

[0021] like Figure 2 , Figure 3and Figure 5 As shown, in a preferred embodiment of the present invention, the portable magnetic particle flaw detector 2 has symmetrically provided storage slots 10 on both sides of its bottom. A magnetic electrode plate 11 is hinged to the outer end of the storage slot 10. A limit structure is provided in the middle of the bottom of the portable magnetic particle flaw detector 2 to constrain the position of the magnetic electrode plate 11. The limiting structure includes a second slide groove 13, a spring 14, a limiting plate 16, and a first slider 17. The second slide groove 13 is located in the middle of the lower end of the portable magnetic particle flaw detector 2. A through groove 15 is provided at the bottom of the second slide groove 13, which is connected to the two side storage grooves 10. The first slider 17 is slidably disposed inside the second slide groove 13. The limiting plate 16 is inserted into the through groove 15 and is fixedly connected to the bottom of the first slider 17. The spring 14 is symmetrically disposed inside the second slide groove 13, and its inner end is fixedly connected to the side of the first slider 17.

[0022] In this embodiment of the utility model, when in use, the limiting plate 16 is pushed to the left, which in turn causes the first slider 17 at its top to overcome the elasticity of the springs 14 on both sides and move to the left, thereby allowing the magnetic electrode plate 11 on the right side to be taken out. Then, the limiting plate 16 is pushed to the right, so that the magnetic electrode plate 11 on the left side can be taken out for operation. By setting a limiting structure at the bottom of the portable magnetic particle flaw detector 2, the magnetic electrode 11 hinged in the storage slot 10 can be constrained to prevent the magnetic electrode 11 from being exposed to the outside when not in operation, which could cause the magnetic electrode 11 to collide with external objects, resulting in damage to the magnetic electrode 11 and rendering it unusable.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the spraying structure includes a low-power pump 5 and a pumping pipe 12. The low-power pump 5 is fixedly installed on the front side of the top of the magnetic flux storage tank 3. An atomizing nozzle 6 is movably installed at the outlet of the magnetic flux storage tank 3. The lower end of the atomizing nozzle 6 is movably installed in the middle of the second slider 19 on the front side. The pumping pipe 12 is located inside the magnetic flux storage tank 3, and its top is movably connected to the inlet at the bottom of the low-power pump 5.

[0024] In this embodiment of the utility model, when in use, the low-power pump 5 on the front side of the top of the magnetic flux storage tank 3 on the right side of the portable magnetic particle flaw detector 2 is started by the control terminal 8 at the top left end of the portable magnetic particle flaw detector 2. The magnetic flux in the storage tank 3 is then pumped into the atomizing nozzle 6 at the front through the pumping pipe 12 at its bottom, and then sprayed from front to back at the welding position of the steel pipe structure 1. By setting up a spraying structure, magnetic flux can be automatically sprayed onto the welded joint of the steel pipe structure 1. The amount of deformation at the welded joint of the steel pipe structure 1 can then be controlled by the accumulation and reflection of the magnetic flux.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the purging structure includes a cleaning fan 4 and an air outlet pipe 22. The cleaning fan 4 is fixedly installed on the rear side of the top of the magnetic suspension liquid storage tank 3, and the air outlet pipe 22 is movably installed at the outlet of the cleaning fan 4, with its lower end movably installed in the middle of the rear second slider 19.

[0026] In this embodiment of the utility model, after the spraying work is completed, the spraying structure stops working, and then the cleaning fan 4 is started to filter the outside air and blow it from back to front through the air outlet pipe 22 at its top, so that the magnetic fluid at the non-welded position of the steel pipe structure 1 is blown away from the welded position of the steel pipe structure 1. By setting up a purging structure, the magnetic flux in the non-welding areas can be removed, leaving only the magnetic flux remaining at the weld deformation area of ​​the steel pipe structure 1. This allows for subsequent control of the welding deformation at the weld deformation area of ​​the steel pipe structure 1 using the remaining magnetic flux.

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, the length of the limiting plate 16 is greater than the length of the through groove 15, and extends into the interior of the receiving groove 10. The thickness of the limiting plate 16 is equal to the height of the through groove 15.

[0028] In this embodiment of the utility model, when in use, by making the length of the limiting plate 16 greater than the length of the through groove 15, and extending it into the interior of the receiving groove 10, the magnetic electrode sheet 11 after being received can be constrained to prevent it from falling off after being received. The thickness of the limiting plate 16 is equal to the height of the through groove 15, thereby facilitating the left and right movement of the limiting plate 16.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment of this utility model, the lower working directions of the spraying structure and the purging structure are arranged opposite to each other, and the high-precision camera 21, the spraying structure and the purging structure move synchronously.

[0030] In this embodiment of the utility model, when in use, by setting the working directions of the lower ends of the spraying structure and the blowing structure to be opposite, the blowing structure can remove the excess magnetic suspension liquid sprayed by the spraying structure, and the high-precision camera 21, the spraying structure and the blowing structure can move synchronously, thereby facilitating the high-precision camera 21 to observe and detect the spraying, blowing and welding deformation in real time.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, a control terminal 8 is fixedly installed on the top left side of the portable magnetic particle flaw detector 2, a battery box 9 is fixedly installed on the left side of the portable magnetic particle flaw detector 2, and a wire groove 20 is opened inside the portable magnetic particle flaw detector 2.

[0032] In this embodiment of the utility model, when in use, a control terminal 8 is fixedly installed on the top left side of the portable magnetic particle flaw detector 2, which facilitates the control of electrical equipment. A storage box 9 is fixedly installed on the left side of the portable magnetic particle flaw detector 2, which can supply power to the control terminal 8 and other electrical equipment. A wire groove 20 is provided inside the portable magnetic particle flaw detector 2, which facilitates the placement of connecting wires between various devices.

[0033] The present invention provides a device for measuring and detecting the welding deformation of steel structure in building engineering in the above embodiments. When measuring and detecting the deformation of the weld seam on the surface of the welded steel pipe structure 1, the bottom limiting plate 16 of the portable magnetic particle flaw detector 2 is moved left and right to release the constraint on the receiving groove 10, thereby allowing the magnetic electrode plate 11 in the receiving groove 10 to be moved out and its angle adjusted so that the magnetic electrode plate 11 can abut against both sides of the steel pipe structure 1 and generate a magnetic field when energized. Then, by using the control terminal 8 at the top left of the portable magnetic particle flaw detector 2, the low-power pump 5 at the front of the top of the magnetic suspension liquid storage tank 3 on the right side of the portable magnetic particle flaw detector 2 is started, thereby pumping the magnetic suspension liquid in the magnetic suspension liquid storage tank 3 into the atomizing spray pipe 6 at the front through the pumping pipe 12 at its bottom, and then spraying it from front to back at the welding position of the steel pipe structure 1. When a deviation in the working position of the atomizing nozzle 6 is found, the lower end of the atomizing nozzle 6 is moved left and right along the first sliding groove 7 on the side of the portable magnetic particle flaw detector 2 by the traction plate 18 and the second slider 19 on its side, thereby adjusting the working position of the lower end of the atomizing nozzle 6. Thus, the working position of the atomizing nozzle 6 can be adjusted without lifting the portable magnetic particle flaw detector 2, reducing the difficulty of adjustment. After the spraying work is completed, the low-power liquid pump 5 stops working, and then the cleaning fan 4 is started. The outside air is then filtered and blown from back to front through the air outlet 22 on its top, which in turn blows the magnetic liquid at the non-welded position of the steel pipe structure 1 away from the welded position of the steel pipe structure 1. At the same time, when the portable magnetic particle flaw detector 2 is working, the high-precision camera 21 at the bottom of the traction plate 18 is activated to observe and detect the welding position. Then, through the internal communication module of the control terminal 8, the captured image is transmitted to the user's mobile terminal in real time. The amount of welding deformation is determined by the reflection or accumulation of residual magnetic fluid at the welding position on the surface of the steel pipe structure 1.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
