Description

Technical Field

[0001] This utility model relates to the field of weld inspection technology, specifically a weld inspection device with digital display function. Background Technology

[0002] Non-destructive testing of welds refers to the inspection of weld quality to ensure it meets specified requirements and design intent without damaging the performance and integrity of the weld being inspected, using methods such as ultrasonic testing, radiographic testing, magnetic particle testing, or penetrant testing. Non-destructive testing of welds is often applied in the field of steel structure pipeline welding. Weld inspection equipment can be used to perform flaw detection on the welded joints of steel structure pipelines, thereby ensuring the strength and tightness of the welded joints.

[0003] When using existing weld inspection equipment, the steel structure pipe to be inspected is usually placed on a suitable rack. Then, the staff will use a handheld ultrasonic flaw detector or other devices to inspect the weld joints of the steel structure pipe. Since most steel structure pipes are cylindrical, the staff needs to constantly rotate the steel structure pipe to change the inspection position. This inspection method, which mainly relies on manual operation, is quite cumbersome. Moreover, when there are too many steel structure pipes to be inspected, it will bring a considerable workload to the staff, which is not conducive to the inspection of steel structure pipe welds.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-8As shown, a weld inspection device with digital display function includes a base 1, a support base 2 fixedly connected to the top surface of the base 1, a control panel 3 fixedly connected to one side of the support base 2, and a controller installed inside the control panel 3.

It should be noted that the controller can be a PLC controller or a microcontroller. Two movable slots 4 are symmetrically arranged on the top of the base 1. An L-shaped plate 5 is provided above the movable slots 4, and a circular groove 7 is provided inside the L-shaped plate 5. A support plate 8 is provided inside the circular groove 7.

The entire structural pipeline rotates, facilitating quick replacement of the inspection position. The bottom of the L-shaped plate 5 is equipped with a first adjustment component 6 that adjusts the position of the third adjustment component 10. By setting the first adjustment component 6, the distance between the two third adjustment components 10 can be adjusted, making the position of the third adjustment component 10 more suitable for the actual length of the steel structural pipeline to be inspected. The upright 17 is installed on the top of the base 1, and a strip seat 18 is provided on one side of the upright 17. Inside the strip seat 18 is an inspection component 20 for performing weld flaw detection.

The driven gear ring 93 and the axis of the support plate 8 are in the same plane. One side of the driven gear ring 93 is connected to the support plate 8. The top of the drive gear 92 meshes with the driven gear ring 93. A first slider 94 is fixedly connected to the outside of the support plate 8. A first groove 95 corresponding to the first slider 94 is opened on the inner wall of the circular groove 7. The first slider 94 is located inside the first groove 95. The first motor 91 is connected to the controller terminal via a data cable. Figure 3 , Figure 6 and Figure 7 As shown, the first motor 91 can drive the drive gear 92 to rotate, and the drive gear 92 then drives the support plate 8 to rotate as a whole through the driven gear ring 93. This makes it easier for staff to quickly change the inspection position of the steel structure pipeline. Compared with common weld inspection devices that mainly rely on manual operation, this utility model simplifies the inspection process of the welded joints of steel structure pipelines, reduces the inspection difficulty of the welded joints of steel structure pipelines, and reduces the workload of staff.

[0033] The third adjustment component 10 includes a motor compartment 101 disposed on one side of the L-shaped plate 5. The motor compartment 101 is fixedly installed on one side of the support plate 8. A second motor 104 is fixedly installed inside the motor compartment 101. A support cylinder 102 is fixedly connected to one side of the motor compartment 101. A bidirectional ball screw 103 is coaxially disposed inside the support cylinder 102. One end of the bidirectional ball screw 103 is rotatably connected to the inner wall of the support cylinder 102. The other end of the bidirectional ball screw 103 passes through the motor compartment 101 and is connected to the output end of the second motor 104. Both ends of the bidirectional ball screw 103 are helically connected to a nut block 105 on their outer sides. Multiple first U-shaped seats 108 are symmetrically installed on the outer side of the nut blocks 105. A limiting groove 1013 corresponding to the first U-shaped seats 108 is opened on the inner wall of the support cylinder 102. The first U-shaped seat 108 is located inside the limiting groove 1013. A first L-shaped seat 106 corresponding to the limiting groove 1013 is provided on the periphery of the support cylinder 102. A second U-shaped seat 109 is fixedly connected to the side of the first L-shaped seat 106 near the support cylinder 102. A connecting rod 1010 is provided between the first U-shaped seat 108 and the second U-shaped seat 109. The connecting rod 1010 is rotatably connected to the first U-shaped seat 108 and the second U-shaped seat 109 via a rotating shaft. A friction pad 107 is fixedly connected to the other side of the first L-shaped seat 106. Multiple second sliders 1011 are symmetrically installed on the outer wall of the nut block 105. A second sliding groove 1012 corresponding to the second slider 1011 is opened on the inner wall of the support cylinder 102. The second slider 1011 is located inside the second sliding groove 1012. Figure 6 , Figure 7 and Figure 8 As shown, the second motor 104 drives the bidirectional ball screw 103 to rotate. Then, the bidirectional ball screw 103 drives the screw nuts 105 at both ends to move closer to each other. Through the cooperation between the first U-shaped seat 108, the second U-shaped seat 109 and the connecting rod 1010, multiple first L-shaped seats 106 can expand outwards simultaneously, thereby positioning and fixing the steel structure pipe to be inspected from both ends, realizing quick clamping of the steel structure pipe. At the same time, in actual use, the friction pad 107 can be made of rubber or silicone material. The friction pad 107 can increase the friction between the first L-shaped seat 106 and the steel structure pipe, making the steel structure pipe less prone to shaking and loosening, which helps to improve the stability of weld inspection work.

[0034] A drive shaft 13 is fixedly connected to the side of the support plate 8 away from the motor compartment 101. A conductive slip ring 12 is provided on the outer side of one end of the drive shaft 13. The rotor of the conductive slip ring 12 is connected to the drive shaft 13. Multiple second L-shaped seats 11 are symmetrically installed on the outer side of the stator of the conductive slip ring 12. One end of the second L-shaped seat 11 is connected to the L-shaped plate 5. The second motor 104 is connected to the rotor terminal of the conductive slip ring 12 via a data cable. The conductive slip ring 12 is connected to the controller terminal via a data cable. Figure 1 , Figure 3 and Figure 6 As shown, by setting the conductive slip ring 12, the data line connected to the second motor 104 can be prevented from being twisted off due to excessive rotation during the process of ensuring stable power supply and signal transmission, thereby improving the working stability of the third adjustment component 10.

[0035] The fourth adjustment component 19 includes a guide groove 191 disposed inside the upright 17. A guide block 192 is slidably connected inside the guide groove 191. A U-shaped frame 195 is fixedly connected to one side of the guide block 192. One end of the U-shaped frame 195 is connected to the strip seat 18. Fixed seats 193 are vertically installed at the top and bottom of the guide groove 191. A second hydraulic cylinder 194 is fixedly installed at the bottom of the lower fixed seat 193. The top of the second hydraulic cylinder 194 passes through the fixed seat 193 and is connected to the guide block 192. The second hydraulic cylinder 194 is connected to the controller terminal via a data cable. Figure 1 , Figure 2 and Figure 3 As shown, after the third adjustment component 10 completes the clamping work of the steel structure pipeline, the second oil cylinder 194 can drive the guide block 192 to slide back and forth along the inner wall of the guide groove 191, so that the strip seat 18 can be moved down as a whole, which facilitates the subsequent weld flaw detection work.

[0036] The inspection component 20 includes an opening 201 located inside a strip-shaped base 18. A limiting frame 202 is fixedly connected to the bottom of the opening 201. A mounting base 203 is located inside the limiting frame 202. An ultrasonic testing probe 204 is fixedly connected to the bottom of the mounting base 203. Third sliders 205 are fixedly connected to both sides of the mounting base 203. A third groove 206 corresponding to the third slider 205 is formed on the inner wall of the limiting frame 202. The third slider 205 is located inside the third groove 206. A positioning plate 207 is fixedly connected to the top of the mounting base 203. Locking bolts 208 are provided at both ends of the positioning plate 207. A fixing groove 209 corresponding to the locking bolts 208 is formed on the top of the strip-shaped base 18. The ultrasonic testing probe 204 is connected to the controller terminal via a data cable. Figure 3 , Figure 4 As shown, in actual use, the ultrasonic testing probe 204 can be moved to the weld of the steel structure pipeline to be inspected via the third slide 206 and the third slider 205. Then, the ultrasonic testing probe 204 can be positioned and fixed as a whole using the locking bolt 208 and the fixing groove 209 to prevent the ultrasonic testing probe 204 from shifting during the inspection process. The ultrasonic testing probe 204 enables the flaw detection inspection of the weld of the steel structure pipeline, which helps to ensure the strength and tightness of the weld of the steel structure pipeline.

[0037] A liquid crystal touch screen 21 is fixedly installed on one side of the control panel 3. The liquid crystal touch screen 21 is connected to the controller via a digital display, such as... Figure 1 , Figure 3 As shown, the detection data from the ultrasonic testing probe 204 is transmitted to the controller in the form of a signal. The controller then displays the detection data to the staff intuitively through the LCD touch screen 21, which makes it easier for the staff to understand the detection status of the welded joints of the steel structure pipeline.

[0038] The top of the support base 2 is provided with a placement groove 16, and multiple U-shaped rods 14 are symmetrically installed on the inner wall of the placement groove 16. Support rollers 15 are rotatably connected to the outer sides of the U-shaped rods 14. Figure 3 , Figure 5 As shown, the support roller 15 on the outside of the U-shaped rod 14 can greatly reduce the friction between the steel structure pipe and the inner wall of the placement groove 16, thereby enabling the steel structure pipe to be better driven by the second adjustment component 9.

[0039] Working principle: First, the operator sends the steel structure pipe to be inspected into the placement groove 16. Then, the distance between the two third adjustment components 10 can be adjusted by the first adjustment component 6, so that the position of the third adjustment component 10 is more suitable to the actual length of the steel structure pipe to be inspected. Then, the third adjustment component 10 can be used to position and fix the steel structure pipe from both ends, thus realizing quick clamping of the steel structure pipe. After the steel structure pipe is clamped, the inspection component 20 is moved downward by the fourth adjustment component 19, which facilitates the weld flaw detection. Then, the inspection component 20 can be used to perform flaw detection inspection of the weld of the steel structure pipe, which helps to ensure the strength and tightness of the weld of the steel structure pipe. At the same time, the steel structure pipe located between the third adjustment components 10 can be rotated by the second adjustment component 9, which facilitates quick change of the inspection position of the steel structure pipe.
