A device for detecting the anti-leakage performance of metal bellows after bending

Abstract

The invention discloses a device for detecting the anti-leakage performance of a metal bellows after bending, and relates to the technical field of material detection and engineering application. When the clamping force is too large, a clamping plate, a short rod, and a positioning rod are used to prevent a slide plate from continuing to move, that is, the movement of the clamping plate is restricted. In this way, an anti-clamping effect is achieved when the bellows is clamped. If the bellows is damaged during the clamping process, it may affect the detection result of its anti-leakage performance. Subsequently, the other end of the bellows is also clamped. At this time, the bellows is in a bent shape. At this time, it is sealed by using a sealant, and then liquid is injected into the other end to detect whether the bellows is leaking. According to the extensibility of the bellows, the bellows can be stretched or contracted with the movement of the telescopic frame, so that tiny leakage points that may have existed originally may become more obvious due to the deformation of the bellows, so as to facilitate faster detection of leakage.

Description

Technical Field

[0001] The invention relates to the technical field of material detection and engineering application, in particular to a device for detecting the anti-leakage performance of a metal bellows after bending. Background Art

[0002] There are some limitations in the existing methods for testing the anti-leakage performance of metal bellows after bending. For example, according to industry specifications, the metal bellows needs to be bent into the arc required by the specifications, and the bent bellows needs to be placed in a vertical position on the ground as required by the specifications. However, most of the existing test instruments are roughly processed and do not have corresponding vertical verification devices. Only manual bending and direct observation of the vertical situation with the naked eye cannot accurately meet the requirements of the specifications. Inaccurate bending arc will directly affect the results of the bellows anti-leakage test. If the bellows are not placed perpendicular to the ground, the hydraulic pressure at the lower end of the bellows will drop after grouting or watering inside the bellows, affecting the test results.

[0003] The patent with the patent announcement number CN214894752U involves the field of material testing and engineering application technology. The patent discloses a device for measuring the anti-leakage performance of a metal bellows after bending, including a detection plate, on which an arc plate is fixedly installed, and on which a number of fixing clamps are installed for fixing the metal bellows to be measured along the arc plate; a limit ring is also provided on the detection plate, and the limit ring is located below the arc plate, and the limit ring is used to limit the lower end of the metal bellows to be measured. By installing a fixing clamp on the arc plate, the patent can quickly complete the fixation of the metal bellows to be measured, improve the efficiency of fixation, and at the end of the test, the metal bellows to be measured can be quickly disassembled without removing the fixing clamp, avoiding the loss of parts.

[0004] In the above patent, at the end of the test, the metal bellows to be measured can be quickly disassembled without removing the fixing clamp, thereby avoiding the loss of parts. However, the current measuring equipment has the following problems: the lack of anti-pinching measures may cause the metal bellows to be squeezed or scratched during the clamping process, thereby causing surface damage. Such damage may destroy the original structure of the bellows and affect its sealing and anti-leakage performance. If only a single angle detection can be performed, potential leakage points of the bellows at other angles may be missed, thereby affecting the accurate judgment of the overall anti-leakage performance of the bellows. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a device for detecting the anti-leakage performance of a metal bellows after bending, which solves the problems raised in the above-mentioned background technology.

[0007] According to the above technical solution, a slot is provided on the side of the limit block close to the skateboard, and a slope is provided on the side of the locking rod close to the short rod. The side of the locking rod close to the slot is provided as a slope. When the short rod moves, it will contact the slope of the locking rod so that the locking rod is inserted into the slot. At this time, the skateboard cannot continue to move, that is, the movement of the splint is restricted. A No. 2 spring is provided between the locking rod and the skateboard, and the locking rod is reset by the No. 2 spring.

[0008] According to the above technical solution, the auxiliary device includes a leak plate, a connecting rod, an extrusion plate and a sealing plug. The leak plate is fixedly installed at the bottom of the lower sliding frame, and the connecting rod rotates to penetrate the upper and lower sides of the leak plate. The circumferential surface of the connecting rod is provided with a second threaded groove, and the extrusion plate is threadedly installed on the circumferential surface of the connecting rod. The sealing plug is arranged on the circumferential surface of the connecting rod. The bellows is clamped after being covered on the outer wall of the sealing plug, and the threaded groove 2 is driven to rotate by rotating the connecting rod. The extrusion plate moves upward through the threaded groove 2. The movement of the extrusion plate will contact the sealing plug, and the sealing plug will expand under the action of pressure, and finally the bottom end of the bellows will be blocked.

[0009] According to the above technical solution, the auxiliary device also includes a connecting button and a hollow block. The connecting button is fixedly installed on the movable end of the telescopic frame, and the hollow block is fixedly installed on the right side of the connecting button. The movement of the connecting button drives the movement of the hollow block.

[0010] According to the above technical solution, the auxiliary device also includes a triangular block, a No. 3 spring and a guide plate. The triangular block is slidably installed on the inner wall of the hollow block. The No. 3 spring is arranged between the hollow block and the triangular block. The triangular block is driven to reset by the arranged No. 3 spring. The guide plate is fixedly installed on the outer wall of the leak plate. When the triangular block moves to the same horizontal line as the limit groove, the No. 3 spring is released and drives the triangular block to be inserted into the limit groove.

[0011] According to the above technical scheme, the collecting device includes a fixed cylinder, a sliding rod, a No. 4 spring and a piston block. The fixed cylinder is fixedly installed on the inner wall of the fixed frame, the sliding rod is slidably installed on the inner wall of the fixed cylinder, the No. 4 spring is arranged between the sliding rod and the fixed cylinder, and the sliding rod is driven to reset by the arranged No. 4 spring. The piston block is fixedly installed on the top of the sliding rod, and hydraulic oil is arranged inside the fixed cylinder. A leakage hole is opened on the top of the piston block. The movement of the sliding rod drives the piston block to move and compresses the No. 4 spring at the same time. The contact between the piston block and the hydraulic oil slows down the reset speed of the No. 4 spring, that is, the reset speed of the sliding rod is slowed down.

[0012] According to the above technical solution, the collecting device also includes a collecting trough and a gear. The collecting trough is fixedly installed on the top of the base, and the gear is rotatably installed on the inner wall of the collecting trough. A water outlet is provided on the front side of the collecting trough. After the seal is released, the liquid in the bellows will flow out from the bottom to the leakage plate and then fall into the collecting trough. The liquid will also fall into the collecting trough along the guide plate.

[0013] According to the above technical solution, the collecting device also includes an L-shaped rod and a sealing rod. The L-shaped rod is slidably installed on the inner wall of the collecting trough, one side of the sealing rod slides through the inner and outer walls of the water outlet, and the other side of the sealing rod is slidably installed on the inner wall of the collecting trough. A tooth groove 1 is provided at the bottom of the L-shaped rod, and a tooth groove 2 is provided at the top of the sealing rod. The tooth groove 1 is meshed with a gear, and the tooth groove 2 is meshed with a gear. When the guide plate translates, it will contact the L-shaped rod to cause the L-shaped rod to move to the left. The L-shaped rod moves through the tooth groove 1 to drive the gear to rotate. The gear rotates and contacts the tooth groove 2 to cause the sealing rod to move to the right. The movement of the sealing rod will gradually open the water outlet.

[0014] The present invention provides a device for detecting the anti-leakage performance of a metal bellows after bending. It has the following beneficial effects: (1) The invention, through the setting of the detection device, fixes one end of the bellows by means of the round rod, the slide plate and the clamping plate. When the clamping force is too large, the slide plate cannot be moved further by means of the clamping plate, the short rod and the positioning rod, that is, the movement of the clamping plate is restricted. In this way, the bellows is prevented from being pinched when being clamped. If the bellows is damaged during the clamping process, it may affect the test result of its anti-leakage performance. The damage on the surface of the bellows may cause leakage in the place where the bellows should not leak during the anti-leakage test, thereby affecting the accurate judgment of the anti-leakage performance of the bellows. Then, the other end of the bellows is clamped in the same way. At this time, the bellows The tube is curved. At this time, it is sealed with sealant, and then liquid is injected into the other end to detect whether the bellows is leaking. The telescopic frame is extended to drive the fixed rod, round rod one and round rod two to move at the same time. According to the extensibility of the bellows, the bellows can be stretched or contracted as the three move. When the bellows is physically extended and contracted, the tiny leakage points that may have existed may become more obvious due to the deformation of the bellows, so as to facilitate faster detection of leakage. During the detection, the fixed rod, round rod one and round rod two can also be rotated to enable detection from more angles, and the electric clamp can be used to detect the bellows with different curvatures.

[0015] (2) This invention, through the setting of auxiliary devices, traditional sealing methods often require the use of materials for sealing. In the absence of these materials, it may lead to an increase in detection time and affect detection efficiency. At this time, the bellows is covered on the outer wall of the sealing plug and clamped, and the sealing plug is contacted with the sealing plug through the connecting rod and the extrusion plate. Under the action of pressure, the sealing plug expands and finally blocks the bottom end of the bellows. In this way, it can still be sealed without the help of external materials, saving materials and reducing detection costs. The telescopic skeleton cannot continue to move upward through the connecting button, hollow block, triangular block, and No. 3 spring. In this way, the telescopic skeleton has a maximum extension distance when extending the bellows, preventing the bellows from being stretched to tear when exceeding this distance without restriction, thereby causing the detection to fail.

[0016] (3) The invention, through the setting of the collecting device, cushions the movement of the telescopic frame through the sliding rod, the piston block and the No. 4 spring, which can make the detection process smoother and reduce the influence of external interference on the detection results, thereby improving the accuracy and reliability of the detection. After the detection is completed, the seal is released, and the liquid in the bellows will flow out from the bottom to the leakage plate and then fall into the collection tank. By collecting the liquid, it is more convenient to observe the state, color and other characteristics of the liquid, which is helpful to analyze the leakage of the bellows, such as whether there is leakage caused by corrosion and other problems. The water outlet is sealed by the sealing rod, and the sealing rod is moved to the right by the guide plate, the L-shaped rod and the gear. The movement of the sealing rod will gradually open the water outlet, allowing the liquid to be discharged from it, so that there is no need for manual discharge. BRIEF DESCRIPTION OF THE DRAWINGS

The No. 1 spring 16 drives the clamp 15 to reset, one side of the short rod 17 is fixedly installed on the surface of the clamp 15, and the other side of the short rod 17 slides through the inner and outer walls of the slide plate 14, and the positioning rod 18 is slidably installed on the surface of the slide plate 14. In this way, the anti-pinching effect of the bellows is achieved when clamping. If the bellows is damaged during the clamping process, it may affect the test results of its anti-leakage performance. Damage to the surface of the bellows may cause leakage in places where the bellows should not leak during the anti-leakage test, thereby affecting the accurate judgment of the anti-leakage performance of the bellows.

[0021] A slot is provided on the side of the limit block 12 close to the slide plate 14, and a slope is provided on the side of the positioning rod 18 close to the short rod 17. The side of the positioning rod 18 close to the slot is provided with a slope.

The movement of the sliding plate 14 drives the clamping plate 15 to move, and the clamping plate 15 will contact the bellows and fix it. When the clamping force is too large, the clamping plate 15 is forced to move in the opposite direction and compress the spring 16 at the same time, and drive the short rod 17 to move. The movement of the short rod 17 will contact the inclined surface of the locking rod 18 so that the locking rod 18 is inserted into the locking groove. At this time, the sliding plate 14 cannot continue to move, that is, the movement of the clamping plate 15 is restricted. In this way, the anti-clamping effect of the bellows is achieved when clamping. If the bellows is damaged during the clamping process, it may affect the test results of its anti-leakage performance. Damage to the surface of the bellows may cause leakage in places where the bellows should not leak during the anti-leakage test, thereby affecting the The anti-leakage performance of the bellows is accurately judged, and then the other end of the bellows is also clamped. At this time, the bellows is in a curved shape. At this time, it is sealed with sealant, and then liquid is injected into the other end to detect whether the bellows is leaking. The output end of the electric push rod 4 moves the U-shaped frame 5 to move. The movement of the U-shaped frame 5 extends the telescopic skeleton 6. The extension of the telescopic skeleton 6 drives the fixed rod 7, round rod 1 8 and round rod 2 9 to move at the same time. According to the extensibility of the bellows, the bellows can be stretched or contracted as the three move. When the bellows is physically extended and contracted, the tiny leakage points that may have existed may become more obvious due to the deformation of the bellows, so as to facilitate faster detection of leakage. During the detection, the fixed rod 7, round rod 1 8 and round rod 2 9 can also be rotated so that detection can be performed from more angles, and the electric clamp 10 can also be used to detect the bellows with different curvatures.

[0023] See also Figure 1-Figure 7 On the basis of the above embodiment, in another embodiment of the present invention, an auxiliary device and a collecting device are arranged above the base 1, and the auxiliary device includes a leak plate 20, a connecting rod 21, an extrusion plate 22 and a sealing plug 23. The leak plate 20 is fixedly installed at the bottom of the lower sliding frame 11, and the connecting rod 21 rotates to penetrate the upper and lower sides of the leak plate 20. The circumferential surface of the connecting rod 21 is provided with a threaded groove 2, and the extrusion plate 22 is threadedly installed on the circumferential surface of the connecting rod 21. The sealing plug 23 is arranged on the circumferential surface of the connecting rod 21. Traditional sealing methods often require the use of materials for sealing. In the absence of these materials, the detection time may be increased, which affects the detection efficiency. In this way, it can still be sealed without the help of external materials, saving materials and reducing the detection cost.

[0024] The auxiliary device also includes a connecting button 24 and a hollow block 25. The connecting button 24 is fixedly installed on the movable end of the telescopic frame 6, and the hollow block 25 is fixedly installed on the right side of the connecting button 24. The movement of the connecting button 24 drives the movement of the hollow block 25.

[0025] The auxiliary device also includes a triangular block 26, a No. 3 spring 27 and a guide plate 28. The triangular block 26 is slidably installed on the inner wall of the hollow block 25. The No. 3 spring 27 is arranged between the hollow block 25 and the triangular block 26. The triangular block 26 is reset by the No. 3 spring. The guide plate 28 is fixedly installed on the outer wall of the leak plate 20. In this way, the telescopic skeleton 6 has a maximum extension distance when extending the bellows, preventing the bellows from being stretched to tear due to exceeding this distance without restriction, thereby causing the detection to fail to proceed normally.

[0026] The collecting device includes a fixed cylinder 30, a sliding rod 31, a No. 4 spring 32 and a piston block 33. The fixed cylinder 30 is fixedly installed on the inner wall of the fixed frame 3, the sliding rod 31 is slidably installed on the inner wall of the fixed cylinder 30, the No. 4 spring 32 is arranged between the sliding rod 31 and the fixed cylinder 30, and the sliding rod 31 is driven to reset by the arranged No. 4 spring 32. The piston block 33 is fixedly installed on the top of the sliding rod 31. Hydraulic oil is arranged inside the fixed cylinder 30, and a leakage hole is opened on the top of the piston block 33. In this way, the movement of the telescopic skeleton 6 is buffered, the detection process can be made smoother, and the influence of external interference on the detection results can be reduced, thereby improving the accuracy and reliability of the detection.

[0027] The collecting device also includes a collecting tank 34 and a gear 35. The collecting tank 34 is fixedly mounted on the top of the base 1, and the gear 35 is rotatably mounted on the inner wall of the collecting tank 34. A water outlet is provided on the front side of the collecting tank 34. By collecting the liquid, it is more convenient to observe the state, color and other characteristics of the liquid, which is helpful to analyze the leakage of the bellows, such as whether there is leakage caused by corrosion and other problems.

[0028] The collecting device also includes an L-shaped rod 36 and a sealing rod 37. The L-shaped rod 36 is slidably installed on the inner wall of the collecting groove 34. One side of the sealing rod 37 slides through the inner and outer walls of the water outlet, and the other side of the sealing rod 37 is slidably installed on the inner wall of the collecting groove 34. A tooth groove 1 is provided at the bottom of the L-shaped rod 36, and a tooth groove 2 is provided at the top of the sealing rod 37. The tooth groove 1 is meshed with the gear 35, and the tooth groove 2 is meshed with the gear 35, so that the liquid can be discharged therefrom without manual discharge.

[0029] When the present embodiment is working, the traditional sealing method often needs to use materials for sealing. In the absence of these materials, the detection time may be increased, affecting the detection efficiency. At this time, the bellows is covered on the outer wall of the sealing plug 23 and clamped, and the thread groove 2 is driven to rotate by rotating the connecting rod 21. The extrusion plate 22 moves upward through the thread groove 2. The movement of the extrusion plate 22 will contact the sealing plug 23, and the sealing plug 23 will expand under the action of pressure, and finally the bottom end of the bellows will be blocked. In this way, it can still be sealed without the help of external materials, saving materials and reducing the detection cost. When the sliding frame 11 moves, it drives the leak plate 20 to move, and the leak plate 20 moves at the same time. When the guide plate 28 is moved, the bottom is sealed all the time. The connecting button 24 is moved by the extension of the telescopic frame 6. The hollow block 25 is moved by the movement of the connecting button 24. At this time, the triangular block 26 is in a state of compressing the No. 3 spring 27. The movement of the hollow block 25 drives the triangular block 26 to move. When the triangular block 26 moves to the same horizontal line as the limiting groove, the No. 3 spring 27 is released and drives the triangular block 26 to insert into the limiting groove. At this time, the telescopic frame 6 cannot continue to move upward. In this way, the telescopic frame 6 has a maximum extension distance when extending the bellows, preventing the bellows from being stretched to tearing due to exceeding this distance without restriction, thereby causing the detection to fail to proceed normally. When the connecting button 24 moves, it will contact the slide bar 31, causing the slide bar 31 to move upward. The movement of the slide bar 31 drives the piston block 33 to move and compresses the No. 4 spring 32 at the same time. The piston block 33 contacts the hydraulic oil, which slows down the reset speed of the No. 4 spring 32, that is, the reset speed of the slide bar 31 is slowed down. In this way, the movement of the telescopic skeleton 6 is buffered, which can make the detection process smoother and reduce the influence of external interference on the detection results, thereby improving the accuracy and reliability of the detection. After the detection is completed, the seal is released, and the liquid in the bellows will flow out from the bottom to the leak plate 20 and then fall into the collection tank 34. The liquid will also fall into the collecting tank 34 along with the guide plate 28. By collecting the liquid, it is more convenient to observe the state, color and other characteristics of the liquid, which is helpful to analyze the leakage of the bellows, for example, whether there is leakage caused by corrosion and other problems. The water outlet is sealed by a sealing rod 37. When the guide plate 28 translates, it will contact the L-shaped rod 36, causing the L-shaped rod 36 to move to the left. The L-shaped rod 36 moves through the tooth groove 1 to drive the gear 35 to rotate. The gear 35 rotates and contacts the tooth groove 2, causing the sealing rod 37 to move to the right. The movement of the sealing rod 37 will gradually open the water outlet, allowing the liquid to be discharged from it, so that there is no need for manual discharge.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
