Description

Technical Field

[0001] This utility model relates to the field of limit bracket technology, and in particular to a non-destructive testing device for pressure vessels. Background Technology

[0002] Non-destructive testing (NDT) equipment for pressure vessels refers to devices used to inspect the internal and surface structure, properties, and condition of pressure vessels without damaging them. Using physical or chemical methods, such as ultrasonic, X-ray, magnetic particle, and penetrant testing, it can detect defects in pressure vessels, such as cracks, pores, and inclusions, to ensure the safe operation of pressure vessels and prevent safety accidents such as explosions and leaks.

[0003] For example, publication number CN216082542U discloses a non-destructive testing device for pressure vessels, including a base and a support column, with the base and support column fixed vertically. A horizontal plate is fixed to the outer surface of the support column, and an infrared flaw detector is installed between the two horizontal plates. A displacement mechanism is connected to the infrared flaw detector, which allows the infrared flaw detector to move up and down. A turntable is installed above the base, and a container body is slidably connected to the top of the turntable. This invention uses a second motor to drive a driving gear, which in turn drives a driven gear, which in turn drives a rotating column, which in turn drives the turntable, allowing the container body to rotate 360 ​​degrees. A first motor drives a transmission belt, which in turn drives a threaded rod, which in turn drives a fixed block, allowing the infrared flaw detector to move up and down. This combination enables the infrared flaw detector to perform full-angle inspection of the outer surface of the container body.

[0004] In the aforementioned patent, a second motor drives a drive gear to rotate, which in turn drives a driven gear to rotate, which in turn drives a rotating column to rotate, which in turn drives a turntable to rotate, allowing the container body to rotate 360 ​​degrees. However, there is still a problem that, after the container is placed on the turntable, there is no limiting structure for the container. The centrifugal force generated when the turntable rotates can easily cause the container to detach from the turntable surface. Therefore, a non-destructive testing device for pressure vessels is needed that can effectively limit the container. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing non-destructive testing devices for pressure vessels, where the container is placed on a turntable without a limiting structure. Therefore, this invention proposes a non-destructive testing device for pressure vessels.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a non-destructive testing device for pressure vessels, comprising a base plate, an electric guide rail, a guide seat, and an infrared flaw detector. A limiting device is provided on one side of the base plate, the limiting device comprising a servo motor, one end of the servo motor being fixedly connected to the base plate, a turntable being fixedly connected to the output end of the servo motor, an anti-slip pad being fixedly connected to the top of the turntable, a triangular frame being fixedly connected to the bottom of the turntable, three electric push rods being fixedly connected to the outer side of the triangular frame, a clamping plate being fixedly connected to the output end of the electric push rods, and an anti-slip plate being fixedly connected to one side of the clamping plate.

[0007] The effect achieved by the above components is that the servo motor starts and drives the turntable to rotate, causing the triangular frame to rotate synchronously, which in turn starts the electric push rod. The output end of the electric push rod then drives the clamping plate to move, thus adjusting the position of the anti-slip pad.

[0008] Preferably, three round rods are fixedly connected to the bottom end of the turntable, and a concave block is fixedly connected to one end of each round rod.

[0009] The effect achieved by the above components is that the concave block is fixed on the round rod, and the round rod is fixed on the turntable.

[0010] Preferably, the inner sides of the three recesses are slidably connected with protruding rings, one end of which is fixedly connected to the base plate.

[0011] The effect achieved by the above components is that the concave block moves and slides on the convex ring.

[0012] Preferably, a fixing frame is fixedly connected to the outer side of the electric push rod, and one side of the three fixing frames is fixedly connected to the turntable.

[0013] The effect achieved by the above components is to stabilize the electric push rod with the fixed frame.

[0014] Preferably, three telescopic rods are fixedly connected to the inner side of the turntable, and the output end of the telescopic rods is fixedly connected to the clamping plate.

[0015] The effect achieved by the above components is that the movement of the clamping plate causes the output end of the telescopic rod to extend or retract, preventing the clamping plate from shifting position during movement.

[0016] Preferably, a support block is fixedly connected to the arc surface of the telescopic rod, and one side of the support block is fixedly connected to the fixed frame.

[0017] The aforementioned components achieve the effect of preventing the telescopic rod from shifting position.

[0018] Preferably, a fixing device is provided on one side of the base plate. The fixing device includes a U-shaped plate, one side of which is fixedly connected to the base plate. Two fixing blocks are fixedly connected to one side of the U-shaped plate, and a handle is fixedly connected to one end of each of the two fixing blocks.

[0019] The above components achieve the following effect: the handle is fixed to the fixing block, the fixing block is fixed to the U-shaped plate, and the U-shaped plate is fixed to the base plate.

[0020] Preferably, the arc surface of the handle is fixedly connected to an anti-slip sleeve, and the arc surface of the handle is fixedly connected to a stabilizing plate.

[0021] The above components achieve the following effects: the anti-slip sleeve increases friction, and the stabilizing plate prevents the handle from deforming.

[0022] Preferably, a stabilizing frame is fixedly connected to one side of the stabilizing plate, and one side of the stabilizing frame is fixedly connected to the U-shaped plate.

[0023] The effect achieved by the above components is to fix the stabilizer between the stabilizer plate and the U-shaped plate.

[0024] In summary, the beneficial effects of this utility model are as follows:

[0025] In this invention, a limiting device is used to limit the container being tested. The container is placed stably on the anti-slip plate, and then the electric push rod is activated. The output end of the electric push rod retracts, driving the clamping plate to move towards the container until the anti-slip pad on the clamping plate contacts the outer edge of the container, thus limiting the container. This limiting device solves the problem in a traditional pressure vessel non-destructive testing device where, after the container is placed on the turntable, there is no limiting structure for the container, and the centrifugal force generated when the turntable rotates easily causes the container to detach from the turntable surface.

[0026] In this invention, by means of a fixing device, when the testing device needs to be moved, the anti-slip sleeve is held and a pulling force is applied to the anti-slip sleeve. The pulling force is transmitted to the fixing block by the handle, and the U-shaped plate drives the base plate to detach from the placement position. The continuously applied pulling force can complete the movement of the testing device. By means of a fixing device, the problem of traditional pressure vessel non-destructive testing devices having few external force points, which makes it inconvenient to apply force for movement, is solved.

[0032] Reference Figure 1 As shown, this utility model provides a technical solution: a pressure vessel non-destructive testing device, including a base plate 1, an electric guide rail 4, a guide seat 5 and an infrared flaw detector 6. A limiting device 2 is provided on one side of the base plate 1, and a fixing device 3 is provided on one side of the base plate 1.

[0033] The specific settings and functions of the limiting device 2 and the fixing device 3 will be explained in detail below.

[0034] Reference Figure 2 and Figure 3As shown in this embodiment: the limiting device 2 includes a servo motor 201, one end of which is fixedly connected to the base plate 1. A turntable 202 is fixedly connected to the output end of the servo motor 201. An anti-slip pad 207 is fixedly connected to the top of the turntable 202, and a triangular frame 203 is fixedly connected to the bottom of the turntable 202. Three electric push rods 204 are fixedly connected to the outer side of the triangular frame 203. A clamping plate 205 is fixedly connected to the output end of the electric push rods 204, and an anti-slip plate 206 is fixedly connected to one side of the clamping plate 205. This achieves the effect of the servo motor 201 starting to drive the turntable 202 to rotate, causing the triangular frame 203 to rotate synchronously, activating the electric push rods 204, and driving the clamping plate 205 to move, thus adjusting the position of the anti-slip pad 207. Three round rods 210 are fixedly connected to the bottom of the turntable 202, and a concave block 211 is fixedly connected to one end of each round rod 210. The concave blocks 211 are fixed to the round rod 210, which in turn is fixed to the turntable 202. A convex ring 212 is slidably connected to the inner side of each of the three concave blocks 211, with one end of the convex ring 212 fixedly connected to the base plate 1. This allows the concave blocks 211 to slide on the convex ring 212. A fixed frame 209 is fixedly connected to the outer side of the electric push rod 204, with one side of each of the three fixed frames 209 fixedly connected to the turntable 202. This ensures the fixed frames 209 provide stability for the electric push rod 204. Three telescopic rods 208 are fixedly connected to the inner side of the turntable 202, with the output end of each telescopic rod 208 fixedly connected to the clamping plate 205. This allows the clamping plate 205 to move, causing the output end of the telescopic rods 208 to extend or retract, preventing the clamping plate 205 from shifting position during movement. A support block 213 is fixedly connected to the arc surface of the telescopic rod 208, with one side of the support block 213 fixedly connected to the fixed frame 209. The support block 213 achieves the effect of preventing the telescopic rod 208 from shifting position.

[0035] Reference Figure 4 As shown in this embodiment: the fixing device 3 includes a U-shaped plate 31, one side of which is fixedly connected to the base plate 1. Two fixing blocks 32 are fixedly connected to one side of the U-shaped plate 31, and a handle 33 is fixedly connected to one end of each fixing block 32. This achieves the effect of fixing the handle 33 to the fixing blocks 32, fixing the fixing blocks 32 to the U-shaped plate 31, and fixing the U-shaped plate 31 to the base plate 1. An anti-slip sleeve 34 is fixedly connected to the arc surface of the handle 33, and a stabilizing plate 35 is fixedly connected to the arc surface of the handle 33. This achieves the effect of increasing friction with the anti-slip sleeve 34 and preventing deformation of the handle 33 with the stabilizing plate 35. A stabilizing frame 36 is fixedly connected to one side of the stabilizing plate 35, and one side of the stabilizing frame 36 is fixedly connected to the U-shaped plate 31. This achieves the effect of fixing the stabilizing frame 36 between the stabilizing plate 35 and the U-shaped plate 31.

[0036] Working principle: When the container to be tested needs to be limited by the limiting device 2, the operator first places the container stably on the anti-slip plate 206, then starts the electric push rod 204. The output end of the electric push rod 204 retracts, driving the clamping plate 205 to move towards the container until the anti-slip pad 207 on the clamping plate 205 contacts the outer edge of the container, thus limiting the container. Then, the electric push rod 204 is turned off. During the movement of the clamping plate 205, the output end of the telescopic rod 208 retracts synchronously to prevent the clamping plate 205 from shifting position. After the container is fixed, the servo motor 201 is started. The output end of the machine 201 drives the turntable 202 to rotate, causing the container to rotate accordingly. The round rod 210 drives the concave block 211 to slide on the convex ring 212, thereby supporting the turntable 202. At the same time, the electric guide rail 4 is controlled to move the guide seat 5 along the axial direction of the electric guide rail 4, thereby driving the infrared flaw detector 6 to adjust its position and unfold the container for inspection. Through the limiting device 2, the problem of traditional pressure vessel non-destructive testing devices, where the container is placed on the turntable 202 without a limiting structure, is solved. The centrifugal force generated when the turntable 202 rotates easily causes the container to detach from the surface of the turntable 202.

[0037] With the fixing device 3, when the testing device needs to be moved, the operator first holds the anti-slip sleeve 34 and applies a pulling force to the anti-slip sleeve 34. The pulling force is transmitted to the fixing block 32 by the handle 33, and the U-shaped plate 31 drives the base plate 1 to leave the placement position. The continuously applied pulling force can complete the movement of the testing device. With the fixing device 3, the problem of traditional pressure vessel non-destructive testing devices having few external force points, which makes it inconvenient to apply force for movement, is solved.
