Description

Technical Field

[0001] The invention relates to the technical field of weld detection, in particular to an intelligent weld detection device with a rotation function. Background Art

[0002] Welds are the key parts that connect structural components. Any defects may lead to structural failure and cause safety accidents. Therefore, it is necessary to test the quality of welds. In the field of weld quality inspection, non-destructive testing technology is the core means to ensure structural safety. However, the functional limitations of probes in the prior art have become a key issue restricting the improvement of inspection efficiency and accuracy. For example, the inspection device mostly uses fixed or linear moving probes. For example, in the steel structure weld inspection device, the probe can only move up and down or left and right, but cannot rotate around the weld axis, resulting in limited inspection angles and difficulty in covering various areas of complex welds (such as circumferential defects of girth welds). The existing weld inspection technology has low inspection efficiency and poor coverage due to the lack of probe rotation function. Summary of the invention

[0003] The purpose of the present invention is to provide a weld intelligent detection device with a rotation function to solve the problems raised in the prior art.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a weld intelligent detection device with a rotation function, comprising a moving mechanism, which serves as a power source for the multi-directional movement of the entire weld intelligent detection device, driving the weld intelligent detection device to move in multiple directions, so as to facilitate the weld intelligent detection device to detect the weld, and also comprising a connecting plate and a detection rod, wherein the connecting plate is connected to the moving mechanism, a base plate is installed on the connecting plate, and a driving member is installed on the base plate, and the driving member causes the detection rod to rotate around its own center, and the detection rod rises one length unit every time the detection rod rotates one circle.

[0005] The base plate is semi-embedded to install the driving component, a housing is installed below the base plate, a rod housing is installed at the output end of the driving component, the detection rod is a hollow probe rod, one end of the probe rod is connected to the rod housing, a detection element is installed in the probe rod, and the housing is arranged on the outside of the probe rod.

[0006] The probe rod is provided with a moving ring, and the casing is provided with a stationary ring adapted to the rotation of the moving ring. The detection rod detects the weld. Each time the driving member drives the detection rod to rotate one circle, the connecting plate and the bottom plate of the moving mechanism step upward by one length unit. The length unit is set according to the detection requirements. The detection rod moves to the upper edge of the weld, stops the detection, and then enters the next weld detection cycle. Through the rotation detection of the weld by the detection rod, on the one hand, the detection range is expanded to avoid multiple detections of the same weld position. On the other hand, welding problems can be discovered earlier, which is conducive to the rapid follow-up of subsequent repair work. This improves welding quality and welding efficiency.

[0007] A threaded rack is provided on the bottom plate, and the detection rod is a hollow threaded rod with a threaded groove on the outer surface. A screw hole matching the threaded groove is provided in the middle of the threaded rack, and the threaded rack is threadedly connected to the threaded rod. Key grooves are symmetrically provided on the threaded rod along the center line direction, and a flat key matching the key groove is provided at the output end of the driving member. The flat key can slide along the key groove. When the driving member rotates the threaded rod through the flat key and the key groove, the threaded rod moves along its own center line direction under the cooperation of the thread groove and the screw hole.

[0008] The connecting plate includes a carrier plate connected to the moving mechanism and a driving shell rotatably connected to the carrier plate, the carrier plate is provided with a driving disk and a bottom ring sleeved on the outside of the driving disk, a disk sleeve is rotatably mounted on the bottom ring, a connecting plate is mounted on the disk sleeve, the driving shell is mounted on the connecting plate, and a rotating plate connected to the bottom plate is mounted on one side of the driving shell. When the bottom plate needs to be driven to rotate so that the threaded rod can detect welds at different angles or positions, the driving disk drives the connecting plate to rotate through the disk sleeve, and the driving shell drives the bottom plate to rotate through the rotating plate under the drive of the connecting plate.

[0009] Two groups of card blocks are symmetrically arranged on the driving housing, each group includes two card blocks, and the card blocks are provided with arc-shaped arc grooves, and the bending directions of the arc grooves on the two groups of card blocks are opposite, and two rotating shafts are symmetrically installed on the rotating plate, and the two rotating shafts are respectively located in the arc grooves of the two groups of card blocks;

[0010] On one side end face of the driving housing close to the rotating plate, there is a groove. In the middle of the groove, there is a through groove penetrating the driving housing. At both ends of the groove, a plurality of side cylinders are symmetrically arranged. On the rotating plate, at the position between two rotating shafts, a plurality of sliding rails are arranged. One sliding rail matches two side cylinders that are in a symmetrical relationship and are distributed at both ends of the groove. On each sliding rail, two tracks are symmetrically arranged. On each track, two sliders are slidably installed. The two sliders are respectively rotatably connected to the two side cylinders. The bending directions of the two arc grooves are opposite, which can prevent the rotating shaft from slipping out of the two arc grooves. In order to adapt to the detection of welds at different heights, angles or positions by the detection rod, with or without using the driving disc, the side cylinders can drive the rotating plate to rotate around one of the rotating shafts, and the other rotating shaft will disengage from the arc groove. When it is necessary to use the side cylinders to drive the rotating plate to rotate around the lower rotating shaft, the two side cylinders on the same sliding rail cooperate with each other (that is, one extends and the other contracts) to drive the two sliders to move up synchronously, so that all the sliders are located at the upper ends of the plurality of sliding rails. Then, the side cylinder in the contracted state starts to extend, and the other side cylinder also extends synchronously, so that the upper rotating shaft gradually moves out of the arc groove. Supported by the lower clamping block, the rotating plate rotates around the lower rotating shaft, so that the detection rod deflects under the drive of the bottom plate; on the contrary, it rotates around the upper rotating shaft. The side cylinders at both ends of the groove are connected to one end of the rotating plate through the sliders and the sliding rails. Furthermore, a stable triangular frame is formed among the side cylinders, the driving housing and the rotating plate, and a plurality of such triangular frames are formed, so that the rotating plate can maintain structural stability during and after the deflection angle process.

[0011] A ball is penetrated through the output end of the side cylinder. The ball is slidably connected to the output end of the side cylinder. On two side cylinders that are located at both ends of the groove and are in a symmetrical relationship, a ball plate is installed. The ball plate is rotatably installed outside the ball. On one side of the plurality of ball plates, a "worker"-shaped pulling plate is commonly installed. In the middle position of the pulling plate, a middle cylinder is rotatably installed. The middle cylinder is located in the through groove and one end is rotatably connected to the connection plate. When the side cylinder drives the rotating plate to rotate around a rotating shaft, the middle cylinder follows the side cylinder to work, and the middle cylinder will contract or extend due to the change in position. The middle cylinder is movably connected to the side cylinder through the ball plate and the pulling plate, and cooperates with the side cylinder to form a plurality of triangular frames.

[0012] The clamping block includes a fixed block fixed on the driving housing and a movable block inserted into the driving housing. On the driving housing, at the position where the movable block is inserted, there is an avoidance groove expanded to one side. The fixed block and the movable block cooperate with each other to form an arc groove;

[0013] "L"-shaped locking plates are symmetrically installed at both ends of the drive housing, one end of the movable block is inserted in the locking plate, a reset spring is arranged between one end of the movable block and the locking plate, and one end of the locking plate is connected to two locking cylinders. When the moving mechanism cannot drive the detection rod to move above the weld due to product structure limitations or installation space limitations, the middle cylinder and the side cylinder can be used at the same time. When driving the rotating plate to move forward, the locking cylinder is controlled to work first, so that the locking cylinder drives the locking plate to move in the direction of the avoidance groove, so that one side surface of the movable block is separated from the surface of the drive housing, so that the movable block can slide freely on the locking plate and the drive housing. The length of the center cylinder is locked, and the position of the pull plate and the ball plate is fixed by the center cylinder. Then the side cylinders on both sides of the groove are extended synchronously. Under the restriction of the center cylinder, the pull plate and the ball plate, the extension direction of the side cylinder is fixed. The two sliders on the same slide rail move in opposite directions. Under the support of the side cylinder and the mutual restriction of the upper and lower side cylinders, the rotating plate pulls the movable block through the rotating shaft (the end face of the movable block that fits the rotating shaft is an arc surface. Under the restriction of the arc surface, the rotating shaft will pull the movable block to move synchronously) to move outward, so that the rotating plate finally moves straight to the top of the weld. The rotating plate, the upper and lower side cylinders, the center cylinder and the movable block cooperate with each other to form multiple triangular frames, which ensures the structural stability of the detection rod during detection.

[0014] The driving component is a hollow T-type reducer, and the output end of the driving component is connected to the driving motor.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When detecting welds, each time the driver drives the detection rod to rotate one circle, the detection rod will step up one length unit until it moves to the upper edge of the weld, stop the detection, and then enter the next weld detection cycle. Through the rotation detection of the detection rod on the weld, on the one hand, the detection range is expanded to avoid multiple detections of the same weld position, and on the other hand, welding problems can be discovered earlier, which is conducive to the rapid follow-up of subsequent repair work. This will improve welding quality and welding efficiency.

[0017] 2. The edge cylinders at both ends of the groove are connected to one end of the rotating plate through sliders and slide rails, thereby forming a stable triangular frame between the edge cylinder, the drive housing and the rotating plate, and there are multiple triangular frames formed, so that the rotating plate can maintain structural stability during and after the deflection angle.

[0031] The detection element can be a miniature camera or an ultrasonic probe to perform visual detection of the weld, or ultrasonic detection.

[0032] Embodiment 1,

[0033] The base plate 2 is semi-embeddedly mounted with the driving component 3, a housing 6 is mounted below the base plate 2, a rod housing 4 is mounted at the output end of the driving component 3, the detection rod is a hollow probe rod 51, one end of the probe rod 51 is connected to the rod housing 4, a detection element is mounted in the probe rod 51, and the housing 6 is sleeved on the outside of the probe rod 51.

[0034] A moving ring 8 is disposed on the probe rod 51 , and a stationary ring 7 adapted to rotate with the moving ring 8 is disposed inside the casing 6 .

[0035] When the driving member 3 drives the probe rod 51 to rotate, the probe rod 51 rotates one circle, and the moving mechanism drives the probe rod 51 to rise one length unit.

[0036] Embodiment 2:

[0037] The bottom plate 2 is provided with a threaded frame 9, and the detection rod is a hollow threaded rod 52 with a thread groove on the outer surface. The detection element is installed inside the threaded rod 52. The middle of the threaded frame 9 is provided with a screw hole adapted to the thread groove. The threaded frame 9 is threadedly connected with the threaded rod 52. The threaded rod 52 is symmetrically provided with key grooves along the center line direction. The output end of the driving member 3 is provided with a flat key matching the key groove, and the flat key can slide along the key groove. When the threaded rod 52 detects the weld through the detection element, the driving member 3 rotates the threaded rod 52 through the flat key and the key groove. Under the cooperation of the thread groove and the screw hole, the threaded rod 52 moves one length unit along its own center line direction.

[0038] The connecting plate 1 includes a carrier plate 10 connected to the moving mechanism and a driving shell 14 rotatably connected to the carrier plate 10. A driving disk 11 and a bottom ring sleeved on the outside of the driving disk 11 are provided on the carrier plate 10. A disk sleeve 12 is rotatably mounted on the bottom ring. A connecting plate 13 is mounted on the disk sleeve 12. The driving shell 14 is mounted on the connecting plate 13. A rotating plate 15 connected to the bottom plate 2 is mounted on one side of the driving shell 14.

[0039] When the base plate 2 needs to be driven to rotate so that the threaded rod 52 can detect welds at different angles or positions, the drive disk 11 drives the connecting plate 13 to rotate through the disk sleeve 12, and the drive shell 14 drives the base plate 2 to rotate through the rotating plate 15 under the drive of the connecting plate 13.

[0040] Two groups of blocks 16 are symmetrically arranged on the driving housing 14, each group includes two blocks 16, and arc-shaped arc grooves 163 are arranged on the blocks 16. The bending directions of the arc grooves 163 on the two groups of blocks 16 are opposite. Two rotating shafts 18 are symmetrically installed on the rotating plate 15, and the two rotating shafts 18 are respectively located in the arc grooves 163 of the two groups of blocks 16.

[0041] The clamping block 16 includes a fixed block 161 fixed on the driving shell 14 and a movable block 162 inserted in the driving shell 14. The driving shell 14 has an avoidance groove extending to one side at the position where the movable block 162 is inserted. The fixed block 161 and the movable block 162 cooperate with each other to form an arc groove 163.

[0042] "L"-shaped locking plates 20 are symmetrically installed at both ends of the drive housing 14, one end of the movable block 162 is inserted into the locking plate 20, a return spring is arranged between one end of the movable block 162 and the locking plate 20, and one end of the locking plate 20 is connected to two locking cylinders 21.

[0043] A groove is provided on the end surface of one side of the driving shell 14 close to the rotating plate 15, and a through groove penetrating the driving shell 14 is provided in the middle of the groove. A plurality of side cylinders 23 are symmetrically provided at both ends of the groove. A plurality of slide rails 17 are provided on the rotating plate 15 between the two rotating shafts 18. One slide rail 17 matches two side cylinders 23 that are in a symmetrical relationship and distributed at both ends of the groove. Two tracks are symmetrically provided on each slide rail 17, and two sliders 19 are slidably installed on each track. The two sliders 19 are rotatably connected to the two side cylinders 23 respectively.

[0044] The bending directions of the two arc grooves 163 are opposite to each other, which can prevent the rotating shaft 18 from slipping out of the two arc grooves 163. In order to adapt the detection rod to detect welds of different heights, angles or positions, when using or not using the driving disk 11, the side cylinder 23 can drive the rotating plate 15 to rotate around one of the rotating shafts 18, and the other rotating shaft 18 will be disengaged from the arc groove 163.

[0045] The output end of the side-position cylinder 23 is penetrated by a ball, and the ball is slidably connected to the output end of the side-position cylinder 23. Ball plates 25 are installed on two side-position cylinders 23 that are located at both ends of the groove and are symmetric. The ball plates 25 are rotatably installed outside the balls. A "worker"-shaped pull plate 24 is commonly installed on one side of multiple ball plates 25. A middle-position cylinder 22 is rotatably installed at the middle position of the pull plate 24. The middle-position cylinder 22 is located in the through groove and one end thereof is rotatably connected to the connection plate 13. When the side-position cylinder 23 drives the rotating plate 15 to rotate around a rotating shaft 18, the middle-position cylinder 22 follows the side-position cylinder 23 to work, and the middle-position cylinder 22 will contract or extend due to the change in position. The middle-position cylinder 22 is movably connected to the side-position cylinder 23 through the ball plates 25 and the pull plate 24, and cooperates with the side-position cylinder 23 to form multiple triangular frames.

[0046] Before detecting the weld seam, if the rotating plate 15 needs to be deflected to send the detection rod into the weld seam, refer to Figure 7 , it is necessary to use the side-position cylinder 23 to drive the rotating plate 15 to rotate around a lower rotating shaft 18. The two side-position cylinders 23 on the same slide rail 17 cooperate with each other, that is, one extends and the other contracts to drive the two sliders 19 to move upward synchronously, so that all the sliders 19 are located at the upper ends of multiple slide rails 17. Then the side-position cylinder 23 in the contracted state starts to extend, and the other side-position cylinder 23 also extends synchronously, so that the upper rotating shaft 18 gradually moves out of the arc-shaped groove 163. Supported by the lower clamping block 16, the rotating plate 15 rotates around the lower rotating shaft 18, so that the detection rod deflects under the drive of the bottom plate 2; otherwise, it rotates around the upper rotating shaft 18. After the angle deflection is completed, the moving mechanism drives the detection rod into the weld seam, and the weld seam is detected by using the detection rod.

[0047] The side-position cylinders 23 at both ends of the groove are both connected to one end of the rotating plate 15 through the sliders 19 and the slide rails 17. Furthermore, a stable triangular frame is formed among the side-position cylinder 23, the drive housing 14 and the rotating plate 15, and multiple such triangular frames are formed, so that the rotating plate 15 can maintain structural stability during and after the angle deflection process.

[0048] Refer to Figure 6 and Figure 7When the moving mechanism cannot drive the detection rod to move above the weld due to product structure limitations or installation space limitations, the center cylinder 22 and the side cylinder 23 can be used simultaneously. When driving the rotating plate 15 to move forward, the locking cylinder 21 is controlled to work first, so that the locking cylinder 21 drives the locking plate 20 to move toward the avoidance groove, so that one side surface of the movable block 162 is separated from the surface of the driving shell 14, so that the movable block 162 can slide freely on the locking plate 20 and the driving shell 14. The length of the middle cylinder 22 is locked, and the positions of the pull plate 24 and the ball plate 25 are fixed by the middle cylinder 22. Then, the side cylinders 23 on both sides of the groove are extended synchronously. Under the restriction of the middle cylinder 22, the pull plate 24 and the ball plate 25, the extension direction of the side cylinder 23 is fixed, and the two sliders 19 on the same slide rail 17 move in opposite directions. Under the support of the side cylinder 23 and the mutual restriction of the upper and lower side cylinders 23, the rotating plate 15 pulls the movable block 162 outward through the rotating shaft 18, so that the rotating plate 15 finally moves straightly above the weld. The moving mechanism sends the threaded rod 52 into the weld for inspection through the connecting plate 1.

[0049] The rotating plate 15, the upper and lower side cylinders 23, the middle cylinder 22 and the movable block 162 cooperate with each other to form a plurality of triangular frames, thereby ensuring the structural stability of the detection rod during detection.

[0050] The working principle of the present invention is as follows: the connecting plate 1 is driven to move by a moving mechanism, so that the connecting plate 1 drives the bottom plate 2, the driving member 3 and the detection rod to move above the weld, and then the moving mechanism extends the detection rod into the weld, and the driving member 3 drives the detection rod to rotate, and the detection rod detects the weld. Each time the detection rod rotates one circle, the detection rod rises one length unit until the detection rod moves to the upper edge of the weld, and then the detection is stopped, and the moving mechanism drives the detection rod to enter the next weld detection cycle.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
