Abstract
Description
Technical Field
[0001] This utility model relates to the field of flaw detection equipment technology, specifically to a steel structure flaw detection equipment that is easy to operate. Background Technology
[0002] A steel structure flaw detector is a non-destructive testing device used to detect internal and surface defects in steel structures. It primarily employs techniques such as ultrasonic waves, magnetic particle testing, X-rays, or penetrant testing to ensure the safety and reliability of the structure. During use, the surface to be tested must first be cleaned, the instrument calibrated, and then the probe is moved along the steel structure or a testing medium is applied. The location, size, and nature of the defects are determined by analyzing the signals or observing the developed images. Finally, the test results are recorded, and whether they meet safety standards is assessed. It is suitable for quality inspection and maintenance of steel structures in buildings, bridges, and ships.
[0003] However, when flaw detectors inspect steel structures, the existing technology involves moving the probe back and forth across the surface of the steel structure to detect any minor damage. However, the probe rubs against the steel structure, and when continuous observation is needed after damage is detected, the operator must hold the probe firmly without moving it, making the operation inconvenient. Furthermore, prolonged probe movement can easily cause friction between the probe and the steel structure, leading to probe wear and affecting its longevity, thus requiring frequent probe replacements.
[0004] In view of this, we propose an easy-to-operate steel structure flaw detection device. Utility Model Content
[0005] The purpose of this utility model is to provide an easy-to-operate steel structure flaw detection device, which solves the problem of wear and tear between the probe and the steel structure and the need for operators to hold it for a long time without moving it.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An easy-to-operate steel structure flaw detection device includes a flaw detector body, a connecting line provided on the rear side of the flaw detector body, and a flaw detection probe fixedly connected to the end of the connecting line away from the flaw detector body; it also includes a control component to prevent wear on the flaw detection probe when detecting flaws in the steel structure, and to ensure smoother and more stable movement of the flaw detection probe; the control component includes a fixing frame, which is sleeved on the outside of the flaw detection probe, a connecting column fixedly connected to the surface of the fixing frame, a base fixedly connected to the end of the connecting column away from the fixing frame, a support rod hinged to the inner side of the connecting column, ball bearing sleeves fixedly connected to the surface of the support rod and the surface of the base, and balls disposed on the inner side of the ball bearing sleeves; the number of connecting columns is four, and the four sets of connecting columns are arranged in a circular array with the center line of the fixing frame as the axis.
[0008] Preferably, a limit baffle is fixedly connected to the surface of the support rod, and a torsion spring is fixedly connected to the surface of the support rod, with the end of the torsion spring away from the support rod being fixedly connected to the surface of the connecting column.
[0009] Preferably, a sliding plate is slidably connected to the inner side of the connecting column, and the side of the sliding plate near the flaw detection probe is fixedly connected to the side of the flaw detection probe.
[0010] Preferably, an abutment rod is fixedly connected to the surface of the slide, and a spring is sleeved on the outer side of the abutment rod. One end of the spring is fixedly connected to the surface of the slide, and the other end of the spring is fixedly connected to the inner side of the connecting column.
[0011] Preferably, a pull rod is slidably connected to the inner side of the support rod, and a linkage block is fixedly connected to one end of the pull rod near the connecting column. The inner side of the linkage block is an inclined surface, and an insertion hole is provided on the inner side of the linkage block.
[0012] Preferably, a rotating rod is hinged to the end of the pull rod away from the linkage block, the rotating rod passes through the support rod, and the rotating rod is hinged to the support rod.
[0013] Preferably, a rubber plug is fixedly connected to the surface of the rotating rod, the end of the rubber plug near the ball is an arc-shaped surface, and a second torsion spring is fixedly connected to the surface of the rotating rod, the end of the second torsion spring away from the rotating rod being fixedly connected to the surface of the support rod.
[0014] By employing the above technical solution, this utility model provides an easy-to-operate steel structure flaw detection device. It possesses at least the following beneficial effects:
[0015] 1. This utility model uses a flaw detection probe to drive a sliding plate to slide within a connecting column. The sliding plate compresses a spring, which is then used to push the sliding plate back to its original position. As the sliding plate slides, it pushes a contact rod to gradually insert into the inner side of the linkage block, causing the contact rod to abut against the inclined surface inside the linkage block. This forces the linkage block to pull a lever. When the lever is pulled, it causes the rotating rod to rotate, thus preventing the rubber plug from contacting the ball bearing. This allows the flaw detection probe to be moved freely for inspection. When the flaw detection probe is released, the spring pushes the sliding plate back to its original position, and the rubber plug is repositioned under the ball bearing when the torsion spring pushes the rotating rod back to its original position, preventing the flaw detection probe from moving again. This facilitates the observation and inspection of the steel structure surface by the operator.
[0016] 2. When the flaw detection probe is used to detect steel structures, the ball bearings at the bottom of the base and the support rod create a gap between the flaw detection probe and the surface of the steel structure, but the distance is not too far to affect the detection. This allows the flaw detection probe to move freely without causing wear on its surface, making the operation convenient. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0025] An easy-to-operate steel structure flaw detection device, such as Figure 1 - Figure 5As shown, the device includes a flaw detector body 1, with a connecting line 3 on the rear side of the flaw detector body 1. A flaw detector probe 4 is fixedly connected to the end of the connecting line 3 furthest from the flaw detector body 1. It also includes a control component 2 to prevent wear on the flaw detector probe 4 during flaw detection of the steel structure, while ensuring smoother and more stable movement of the flaw detector probe 4. The control component 2 includes a mounting frame 21, which is sleeved on the outside of the flaw detector probe 4. A connecting post 22 is fixedly connected to the surface of the mounting frame 21, and a base 23 is fixedly connected to the end of the connecting post 22 furthest from the mounting frame 21. A support rod 24 is hinged to the inner side of the connecting post 22. The flaw detector body 1 is activated first, then the flaw detector probe 4 is grasped and aligned with the steel structure to be inspected. Then, the support rod 24 is slightly moved so that it can move on the base. When the base 23 is pushed, it opens up and then pushes the fixed frame 21. The surface of the support rod 24 and the surface of the base 23 are both fixedly connected with ball sleeves 25. The inner side of the ball sleeves 25 is provided with balls 26. Since the fixed frame 21 and the base 23 are fixedly connected with connecting columns 22, when the fixed frame 21 is pushed, it will push the base 23 through the connecting columns 22. Because the support rod 24 is moved in advance, the support rod 24 is already at an angle with the connecting columns 22. As the base 23 is pushed, the support rod 24 will gradually open up, causing the support rod 24 to rotate to a certain extent. The balls 26 at the bottom of the support rod 24 will also fit against the surface of the steel structure to be detected. There are four sets of connecting columns 22, and the four sets of connecting columns 22 are arranged in a circular array with the center line of the fixed frame 21 as the axis. A limit baffle 27 is fixedly connected to the surface of the support rod 24. A torsion spring 28 is also fixedly connected to the surface of the support rod 24, with the end of the torsion spring 28 away from the support rod 24 fixedly connected to the surface of the connecting column 22. A slider 29 is slidably connected to the inner side of the connecting column 22, with the side of the slider 29 near the flaw detector 4 fixedly connected to the side of the flaw detector 4. An abutment rod 210 is fixedly connected to the surface of the slider 29, with a spring 211 sleeved on the outer side of the abutment rod 210. One end of the spring 211 is fixedly connected to the surface of the slider 29, and the other end of the spring 211 is fixedly connected to the inner side of the connecting column 22. A pull rod 217 is slidably connected to the inner side of the support rod 24. The pull rod 217 pushes the flaw detection probe 4 to drive the slider 29 to slide inside the connecting column 22. The slider 29 will compress the spring 211, which is used for the spring 211 to push the slider 29 to reset. When the slider 29 slides, it will push the abutment rod 210 to gradually insert into the inner side of the linkage block 212, so that the abutment rod 210 abuts against the inclined surface of the inner side of the linkage block 212, thereby forcing the linkage block 212 to pull the pull rod 217. When the pull rod 217 is pulled, it will drive the rotating rod 214 to rotate, so that the rubber plug 215 no longer abuts against the ball 26, thereby allowing the flaw detection probe 4 to be moved freely for detection. The end of the pull rod 217 near the connecting column 22 is fixedly connected to the linkage block 212. The inner side of the linkage block 212 is an inclined surface, and the inner side of the linkage block 212 is provided with an insertion hole 213.A rotating rod 214 is hinged to the end of the pull rod 217 away from the linkage block 212. The rotating rod 214 passes through the support rod 24 and is hinged to the support rod 24. A rubber plug 215 is fixedly connected to the surface of the rotating rod 214. When the support rod 24 rotates, it will drive the limiting baffle 27 to rotate along with it. The limiting baffle 27 will compress the torsion spring 28 to facilitate the subsequent pull of the support rod 24 back to its original position. At the same time, the balls 26 in the ball sleeve 25 on the base 23 and the balls 26 in the ball sleeve 25 on the support rod 24 are in contact with the surface of the steel structure. However, at this time, the side of the balls 26 in the ball sleeve 25 on the support rod 24 is blocked by the rubber plug 215 and cannot roll. The end of the rubber plug 215 near the balls 26 is an arc-shaped surface. A torsion spring 216 is fixedly connected to the surface of the rotating rod 214. The end of the torsion spring 216 away from the rotating rod 214 is fixedly connected to the surface of the support rod 24.
[0026] In using this easy-to-operate steel structure flaw detection device, first start the flaw detector body 1, then grasp the flaw detection probe 4 and align it with the steel structure to be inspected. Then, slightly move the support rod 24 so that it can open when the base 23 is pushed. Next, push the fixing frame 21. Since the fixing frame 21 is fixedly connected to the base 23 by a connecting column 22, when the fixing frame 21 is pushed, it will push the base 23 through the connecting column 22. Because the support rod 24 was moved in advance, it is already connected to the connecting column 22. There is an angle between them, and as the base 23 is pushed, the support rod 24 will gradually open, causing the support rod 24 to rotate to a certain extent. The ball bearings 26 at the bottom of the support rod 24 will also come into contact with the surface of the steel structure to be probed. When the support rod 24 rotates, it will drive the limiting baffle 27 to rotate along with it, and the limiting baffle 27 will compress the torsion spring 28, so that the support rod 24 can be pulled back to its original position later. The ball bearings 26 in the ball bearing sleeve 25 on the base 23 and the ball bearings 26 in the ball bearing sleeve 25 on the support rod 24 are in contact with the surface of the steel structure. The surfaces are in contact simultaneously, but at this time, the sides of the balls 26 inside the ball sleeve 25 on the support rod 24 are blocked by the rubber plug 215 and cannot roll. If it is necessary to move the flaw detection probe 4, the flaw detection probe 4 can be pushed to drive the slider 29 to slide inside the connecting column 22. The slider 29 will compress the spring 211, which is used for the spring 211 to push the slider 29 to reset. When the slider 29 slides, it will push the abutment rod 210 to gradually insert into the inner side of the linkage block 212, so that the abutment rod 210 abuts against the inclined surface of the inner side of the linkage block 212, thereby forcing The linkage block 212 pulls the lever 217. When the lever 217 is pulled, it will drive the rotating rod 214 to rotate, so that the rubber plug 215 no longer resists the ball 26. This allows the flaw detector 4 to be moved freely for inspection. When the flaw detector 4 is released, the spring 211 will push the slider 29 to reset, and the rubber plug 215 will be pushed back under the ball 26 when the torsion spring 216 pushes the rotating rod 214 to reset, so that the flaw detector 4 cannot be moved again, making it convenient for staff to observe and inspect the surface of the steel structure.
[0027] When the flaw detector 4 detects the steel structure, the base 23 and the ball bearings 26 at the bottom of the support rod 24 create a gap between the flaw detector 4 and the surface of the steel structure, but the distance is not too far to affect the detection of the flaw detector 4. This allows the flaw detector 4 to move freely without causing wear on its surface, making the operation convenient.
