Description

Technical Field

[0001] The present application belongs to the technical field of non-destructive testing of boiler tube panel welded joints, and in particular, relates to a device for non-destructive testing of boiler tube panel welded joints. Background Art

[0002] During the shutdown and maintenance period, the welding joints of the superheater pipes on the heating surface of the boiler need to be non-destructively tested. During the inspection process, X-ray flaw detection technology is usually required. Since the interior of the boiler is a suspended steel frame structure with no fixed support points, a large number of scaffoldings need to be built in advance as a supporting structure. This solution is labor-intensive and time-consuming, which directly affects the start-up time of the generator set, resulting in increased maintenance costs for the power plant and reduced power generation revenue.

[0003] The patent with publication number CN112304980A discloses a directional X-ray flaw detector support device for non-destructive testing of boiler tube panel welding joints and a method of using the same. The support frame is mounted on the boiler tube panel, and a support plate is mounted on the support frame. A flaw detector bracket is placed on the support plate, and a directional X-ray flaw detector is placed on the flaw detector bracket. The device is fixed to the boiler internal tube panel through a pipe clamp as a supporting structure by two diagonal support brackets. The support plates laid on the horizontal cross bars of the two diagonal support brackets are used to support the flaw detector bracket. The directional X-ray flaw detector is placed on the insulating rubber pad of the support ring, and the flaw detector bracket can be pushed to perform non-destructive testing on welding joints at the same height.

[0004] The above patent does not need to build a large number of scaffoldings. It supports the device by building two diagonal bracing brackets and using several diagonal bracing brackets as supporting structures. However, in actual use, the above patent places the flaw detector through a support plate, and adjusts the height of the flaw detector through screws and support rings. Although the height can be adjusted, the adjustment height is limited, and as the height gradually increases, the supporting effect will gradually deteriorate and become more and more dangerous, which needs to be improved. Summary of the invention

[0005] The purpose of this application is to provide a device for non-destructive testing of boiler tube panel welding joints, which can solve the above-mentioned problems.

[0006] The purpose of the present application is to provide a boiler tube panel welding joint non-destructive testing device, including a boiler tube panel support frame and a flaw detector, and also includes a supporting device for supporting the flaw detector, the supporting device including:

[0007] Fixed frame;

[0008] The clamping device is arranged on the fixing frame and can move up and down on the fixing frame;

[0009] Control devices;

[0010] The control device controls the clamping device to rise and fall on the fixing frame.

[0011] The above-mentioned equipment for non-destructive testing of boiler tube panel welded joints is adopted, and the fixed frame is used as the main structure of the supporting equipment to provide a stable support platform for the subsequent clamping device and control device. The clamping device is arranged on the fixed frame and can move up and down in the vertical direction on the fixed frame. The main function of the clamping device is to firmly clamp the flaw detector to ensure its stability and accuracy during the detection process. The control device is connected to the clamping device and is used to control the lifting and lowering movement of the clamping device on the fixed frame. Through the control device, the operator can easily adjust the height of the flaw detector to meet the detection requirements of boiler tube panel welded joints of different heights. By adopting the method of using the control device to drive the clamping device to move up and down on the fixed frame, the height adjustment range of the flaw detector of the present application is expanded, which makes it easier for the operator to adapt to the detection requirements of boiler tube panel welded joints of different heights, and improves the detection efficiency and accuracy. And as the height of the flaw detector increases, the traditional support method often has the problem of poor support effect. The support equipment of the present application ensures that the flaw detector can obtain a stable support effect at different heights through the close cooperation between the fixed frame and the clamping device, reduces the safety risks in the detection process, improves the reliability of the equipment, and avoids the safety hazards such as shaking and falling off that may occur in traditional support methods.

[0012] Furthermore, the fixing frame includes:

[0013] Base;

[0014] The mounting frame is arranged on the base, is a rectangular frame and is arranged obliquely, and a movable space for the clamping device to move is arranged in the middle thereof;

[0015] A guide groove is provided on the mounting frame, and guide slide bars cooperating with the guide groove are provided on both sides of the clamping device;

[0016] It also includes a driving mechanism, which is arranged on the base and connected to the clamping device, and is used to drive the clamping device to move up and down along the guide groove.

[0017] The base, as the basic part of the fixing frame, provides a stable support surface to ensure the stability of the entire fixing frame structure. The mounting frame is arranged on the base, presenting a rectangular frame structure, and is arranged at an angle, which helps to increase the structural strength and stability of the fixing frame, and is also conducive to the movement of the clamping device in the activity space. There is an activity space for the clamping device to move in the middle of the mounting frame. The guide groove is arranged on the mounting frame to provide guidance for the movement of the clamping device. The shape and size of the guide groove match the guide slide bar on the clamping device to ensure that the clamping device can move smoothly along the guide groove. Guide slide bars that cooperate with the guide groove are arranged on both sides of the clamping device. The guide slide bars are inserted into the guide grooves, so that the clamping device can move up and down along the guide grooves, which helps to maintain the stability and accuracy of the clamping device during the movement. The driving mechanism is arranged on the base and connected to the clamping device to provide power to drive the clamping device to move up and down along the guide groove.

[0018] The fixed frame forms a stable support structure through the close cooperation of the base, mounting frame, guide groove and guide slide bar, which can ensure the stability and accuracy of the clamping device during movement and improve the detection efficiency. The setting of the drive mechanism enables the clamping device to move up and down along the guide groove, thereby realizing the flexible adjustment of the height of the flaw detector. It not only has a large range but also high precision, which can meet the detection needs of boiler tube screen welding joints of different heights. At the same time, through the cooperation of the guide groove and the guide slide bar, as well as the precise control of the drive mechanism, the stability and safety of the clamping device during movement are ensured.

[0019] Further: the driving mechanism comprises:

[0020] A winder is arranged on the base;

[0021] A guide wheel is arranged on the mounting frame;

[0022] A sliding buffer structure is arranged in the guide groove and connected to the guide slide rod;

[0023] A connecting crossbar is arranged on the clamping device;

[0024] Among them, a pull rope is arranged on the winder, and the other end of the pull rope passes through the guide wheel and is connected to the connecting cross bar.

[0025] The winder is arranged on the base, and is responsible for providing the power for winding and releasing the pull rope, thereby driving the clamping device to move up and down along the guide groove. The guide wheel is arranged on the mounting frame, and is used to change the movement direction of the pull rope, and guide it to smoothly pass through the mounting frame and connect to the connecting cross bar. The sliding buffer structure is arranged in the guide groove and connected to the guide slide bar. It is used to absorb the impact and vibration of the clamping device during the movement, and ensure the stability of the flaw detector when adjusting up and down. The connecting cross bar is arranged on the clamping device, which is the connecting component between the pull rope and the clamping device, and is responsible for transmitting the tension of the pull rope to the clamping device, thereby driving it to move up and down. The pull rope is responsible for transmitting the power of the winder, thereby driving the clamping device to move up and down. It is made of high-strength, wear-resistant and corrosion-resistant materials to ensure its reliability and safety in long-term use. The locking mechanism is used to fix the position of the clamping device after it is adjusted to the desired position. This can ensure that the flaw detector will not move or shake due to external factors during the detection process, thereby improving the accuracy and safety of the detection. The locking mechanism can adopt a variety of locking mechanisms in the existing technology, such as locking bolts, locking buckles, etc., to adapt to different application scenarios and needs.

[0026] Through the close cooperation of the winder, guide wheel, sliding buffer structure and connecting cross bar, the driving mechanism can realize flexible adjustment of the height of the clamping device and the flaw detector. At the same time, the existence of the sliding buffer structure also ensures the stability of the flaw detector during the up and down adjustment process, avoiding errors and safety hazards caused by impact and vibration. The overall design of the driving mechanism of the present application is compact and reasonable, and the connection between the various components is tight and stable, which ensures the reliability and stability of the driving mechanism during long-term use and reduces the failure rate and maintenance cost. The existence of the locking mechanism allows the operator to easily fix it after adjusting the height of the clamping device and the flaw detector. It not only simplifies the operation process, but also improves the safety of operation and avoids safety accidents caused by improper operation.

[0027] Furthermore, the sliding buffer structure includes:

[0028] A first guide groove is disposed in the guide groove;

[0029] The damping assembly comprises a piston rod and a barrel, wherein one end of the piston rod away from the barrel is fixed to the bottom of the first guide groove, and the barrel is slidably disposed in the first guide groove;

[0030] A first spring is disposed in the first guide groove, and two ends of the first spring are respectively connected to the top of the first guide groove and an end of the cylinder away from the piston rod;

[0031] A guide buffer assembly is disposed in the first guide groove and connected to the barrel;

[0032] Wherein, two ends of the first spring are fixedly connected to the top of the first guide groove and the barrel.

[0033] The first guide groove is arranged in the guide groove, which provides a limited movement space for the sliding buffer structure, ensuring the stability and accuracy of the barrel during the sliding process. As the core component of the sliding buffer structure, the damping assembly includes a piston rod and a barrel, one end of the piston rod is fixedly connected to the bottom of the first guide groove, and the barrel is slidably arranged in the first guide groove. When the clamping device moves along the guide groove, the barrel will slide in the first guide groove, and the movement of the piston rod relative to the barrel will produce a damping effect, thereby slowing down the movement speed of the clamping device and increasing stability. The first spring is arranged in the first guide groove, and its two ends are respectively connected to the top of the first guide groove and the end of the barrel away from the piston rod. Its telescopic effect can further absorb the impact and vibration of the clamping device during the movement, thereby improving the buffering effect. The guide buffer assembly is arranged in the first guide groove and connected to the barrel, which is used to guide the sliding of the barrel in the first guide groove and further enhance the buffering effect.

[0034] Through the close cooperation between the damping assembly and the first spring, the sliding buffer structure can significantly absorb the impact and vibration of the clamping device during movement, which can not only improve the stability of the flaw detector when adjusting up and down, but also extend the service life of the equipment. The existence of the damping assembly slows down the speed of the clamping device during movement, thereby achieving a smooth adjustment effect, helping the operator to more accurately control the height of the flaw detector and improve the accuracy and safety of detection.

[0035] Furthermore, the guide buffer assembly includes:

[0036] A second guide groove is disposed in the guide groove;

[0037] A first sliding block is connected to an end of the barrel away from the first spring and is slidably disposed in the second guide groove;

[0038] A second sliding block is disposed in the second guide groove and is hinged to the first sliding block;

[0039] a second spring, one end of which is connected to the second slider, and the other end of which is connected to the top of the second guide groove;

[0040] Wherein, a through hole is arranged on the first sliding block for the second spring to pass through.

[0041] The second guide groove is arranged in the guide groove, providing a limited movement space for the first slider and the second slider, ensuring the stability and accuracy of the slider during the sliding process. The first slider is connected to the end of the barrel away from the first spring, and is slidably arranged in the second guide groove. When the barrel slides in the first guide groove, the first slider will slide in the second guide groove accordingly. The second slider is arranged in the second guide groove and is connected to the first slider by a hinged manner. This connection mode enables the second slider to change the angle between the second slider and the first slider, which is convenient for the first slider to cooperate with the second guide groove. One end of the second spring is connected to the second slider, and the other end is connected to the top of the second guide groove. When the first slider and the second slider slide in the second guide groove, the second spring will expand and contract, thereby further absorbing impact and vibration. A through hole is provided on the first slider for the second spring to pass through, which ensures that the second spring can be correctly connected to the first slider and the second slider and play its buffering role.

[0042] Through the close cooperation of the first slider, the second slider and the second spring, the guide buffer assembly can further enhance the buffering effect of the sliding buffer structure. When the clamping device moves, the second spring will expand and contract, thereby absorbing the energy generated during the movement and improving the stability of the device. At the same time, the angle change of the second slider relative to the first slider enables the guide buffer assembly to better adapt to the change of the second guide groove path during the sliding process, thereby improving the stability of the adjustment.

[0043] Furthermore, the second guide groove includes a guide section and a limit section, the guide section is arranged straightly, the limit section is arc-shaped, and the second sliding block cooperates with the limit section and can slide into the limit section.

[0044] The guide section is arranged straightly to provide a stable sliding path for the first slider and the second slider. When the clamping device moves normally, the slider mainly slides in the guide section. The limiting section is arc-shaped and connected to the guide section. When the second slider slides to the end of the guide section, it enters the limiting section, which is intended to limit its further movement by changing the moving direction of the slider and provide an additional buffering effect. The second slider is designed to cooperate with the limiting section and slide into the limiting section during the sliding process. When the slider enters the limiting section, its moving direction changes, thereby limiting the further movement of the clamping device.

[0045] By setting a limit section, when the slider slides to the end of the guide section, it will enter the limit section and be restricted by it, which can prevent the clamping device from continuing to move downward in unexpected situations such as the breakage of the pull rope, thereby protecting the safety of equipment and personnel. At the same time, the arc-shaped design of the limit section enables the slider to change the direction of movement when sliding in, thereby dispersing the force during the downward movement in the arc direction. The dispersion effect can reduce the impact on equipment and personnel and improve the buffering effect. In unexpected situations such as the breakage of the pull rope, the clamping device and the flaw detector may move downward rapidly due to loss of support. The present application can slow down the downward movement speed and reduce the impact force by setting a limit section and dispersing the impact force, thereby improving the safety of equipment and personnel.

[0046] Furthermore, first sliding protrusions are provided on both sides of the first sliding block and the second sliding block, the cross section of the first sliding protrusion is circular, and a first limiting sliding groove cooperating with the first sliding protrusion is provided on the side wall of the second guide groove.

[0047] The first slider is connected to the barrel, and the second slider is hinged to the first slider. The two sliders slide together in the second guide groove, ensuring the stability and accuracy of the slider during the sliding process. The first slider and the second slider are both provided with first sliding protrusions on both sides. The cross-sections of these protrusions are circular. The circular cross-section design enables the sliding protrusions to better adapt to the shape of the first limiting slide groove during the sliding process, reducing friction and wear.

[0048] The side wall of the second guide groove is provided with a first limiting groove that cooperates with the first sliding protrusion. The shape and size of these grooves match the first sliding protrusion, ensuring the stability and accuracy of the slider during the sliding process. The cooperation between the first sliding protrusion and the first limiting groove enables the slider to remain stable during the sliding process, and is not prone to displacement or shaking, which helps to improve the overall stability and accuracy of the equipment. At the same time, the first sliding protrusion with a circular cross-section can better adapt to the shape of the first limiting groove, thereby reducing friction and wear during the sliding process, helping to extend the service life of the equipment and reduce maintenance costs. In addition, the design of the first limiting groove provides a clear sliding path for the slider, enhances guidance, facilitates the movement of the first slider and the second slider, and improves reliability.

[0049] Furthermore, a second limiting sliding groove adapted to the barrel portion is provided in the first guide groove, and a second sliding protrusion adapted to the second limiting sliding groove is provided on the barrel portion.

[0050] The second limiting slide groove is arranged in the first guide groove, and its shape and size match the second sliding protrusion on the barrel, which can ensure the stability and accuracy of the barrel when sliding in the first guide groove. The second sliding protrusion is arranged on the outer surface of the barrel and is adapted to the second limiting slide groove. When the barrel slides in the first guide groove, the second sliding protrusion will fit closely with the second limiting slide groove, which not only ensures the stable sliding of the barrel, but also prevents the barrel from deflecting or shaking during the sliding process, which helps to improve the overall stability and accuracy of the sliding buffer structure.

[0051] The beneficial effects of this application are:

[0052] 1. By using a control device to drive the clamping device to move up and down on the fixed frame, the height adjustment range of the flaw detector of the present application is expanded, which allows operators to more conveniently adapt to the inspection requirements of boiler tube panel welding joints at different heights, improving the inspection efficiency and accuracy. It also ensures that the flaw detector can obtain a stable support effect at different heights, reducing the safety risks during the inspection process;

[0053] 2. Through the close cooperation between the damping component and the first spring, the sliding buffer structure can significantly absorb the impact and vibration of the clamping device during movement, which can not only improve the stability of the flaw detector when adjusting up and down, but also extend the service life of the equipment. The existence of the damping component slows down the speed of the clamping device during movement, thereby achieving a smooth adjustment effect, helping the operator to more accurately control the height of the flaw detector and improve the accuracy and safety of detection;

[0054] 3. By setting the limit section, the clamping device can be prevented from continuing to move down in unexpected situations such as rope breakage, thereby protecting the safety of equipment and personnel. At the same time, the arc design of the limit section allows the slider to change the direction of movement when sliding in, thereby dispersing the force during downward movement in the arc direction, reducing the impact on equipment and personnel and improving the buffering effect. In unexpected situations such as rope breakage, by setting the limit section and dispersing the impact force, the downward movement speed can be slowed down and the impact force can be reduced, thereby improving the safety of equipment and personnel.

[0088] The winder 310 is provided with a pull rope 340 , and the other end of the pull rope 340 passes through the guide wheel 320 and is connected to the connecting cross bar 330 .

[0089] In the embodiment of the present application, the winder 310 is arranged on the base 110, and is responsible for providing the power for winding and releasing the pull rope 340, thereby driving the clamping device 200 to move up and down along the guide groove 122. The guide wheel 320 is arranged on the mounting frame 120, and is used to change the movement direction of the pull rope 340, and guide it to smoothly pass through the mounting frame 120, and is connected to the connecting cross bar 330.

It is used to absorb the impact and vibration of the clamping device 200 during the movement process, and ensure the stability of the flaw detector when it is adjusted up and down. The connecting cross bar 330 is arranged on the clamping device 200, and is a connecting component between the pull rope 340 and the clamping device 200, and is responsible for transmitting the pulling force of the pull rope 340 to the clamping device 200, thereby driving it to move up and down. The pull rope 340 is responsible for transmitting the power of the winder 310, thereby driving the clamping device 200 to move up and down. It is made of high-strength, wear-resistant and corrosion-resistant materials to ensure its reliability and safety in long-term use. The locking mechanism is used to fix the position of the clamping device 200 after it is adjusted to the desired position, which can ensure that the flaw detector will not move or shake due to external factors during the detection process, thereby improving the accuracy and safety of the detection.

The overall design of the driving mechanism 300 of the present application is compact and reasonable, and the connection between the various components is tight and stable, which ensures the reliability and stability of the driving mechanism 300 during long-term use and reduces the failure rate and maintenance cost. The existence of the locking mechanism allows the operator to easily fix it after adjusting the height of the clamping device 200 and the flaw detector. It not only simplifies the operation process, but also improves the safety of operation and avoids safety accidents caused by improper operation.

[0091] Embodiment 4:

[0092] An embodiment of the present application provides a device for non-destructive testing of boiler tube panel welded joints. In addition to the above-mentioned technical features, the device for non-destructive testing of boiler tube panel welded joints in the embodiment of the present application also includes the following technical features.

[0093] like Figure 3 and Figure 4 As shown, the sliding buffer structure 400 includes:

[0094] A first guide groove 410 is disposed in the guide groove 122;

[0095] The damping assembly 420 includes a piston rod 421 and a barrel 422. One end of the piston rod 421 away from the barrel 422 is fixed to the bottom of the first guide groove 410, and the barrel 422 is slidably disposed in the first guide groove 410.

[0096] The first spring 430 is disposed in the first guide groove 410, and its two ends are respectively connected to the top of the first guide groove 410 and an end of the cylinder 422 away from the piston rod 421;

[0097] The guide buffer assembly 500 is disposed in the first guide groove 410 and connected to the barrel 422;

[0098] The two ends of the first spring 430 are fixedly connected to the top of the first guide groove 410 and the cylinder portion 422 .

[0099] In the embodiment of the present application, the first guide groove 410 is arranged in the guide groove 122, providing a limited movement space for the sliding buffer structure 400, ensuring the stability and accuracy of the barrel 422 during the sliding process. The damping assembly 420, as the core component of the sliding buffer structure 400, includes a piston rod 421 and a barrel 422, one end of the piston rod 421 is fixedly connected to the bottom of the first guide groove 410, and the barrel 422 is slidably arranged in the first guide groove 410. When the clamping device 200 moves along the guide groove 122, the barrel 422 will slide in the first guide groove 410, and the movement of the piston rod 421 relative to the barrel 422 will produce a damping effect, thereby slowing down the movement speed of the clamping device 200 and increasing stability. The first spring 430 is disposed in the first guide groove 410, and its two ends are respectively connected to the top of the first guide groove 410 and the end of the cylinder 422 away from the piston rod 421. Its telescopic effect can further absorb the impact and vibration of the clamping device 200 during the movement, thereby improving the buffering effect. The guide buffer assembly 500 is disposed in the first guide groove 410 and connected to the cylinder 422, and is used to guide the sliding of the cylinder 422 in the first guide groove 410 and further enhance the buffering effect.

[0100] Through the close cooperation between the damping assembly 420 and the first spring 430, the sliding buffer structure 400 can significantly absorb the impact and vibration of the clamping device 200 during the movement, which can not only improve the stability of the flaw detector when adjusting up and down, but also extend the service life of the equipment. In addition, the existence of the damping assembly 420 slows down the speed of the clamping device 200 during the movement, thereby achieving a smooth adjustment effect, helping the operator to more accurately control the height of the flaw detector and improve the accuracy and safety of detection.

[0101] Embodiment 5:

[0102] An embodiment of the present application provides a device for non-destructive testing of boiler tube panel welded joints. In addition to the above-mentioned technical features, the device for non-destructive testing of boiler tube panel welded joints in the embodiment of the present application also includes the following technical features.

[0103] like Figure 3 and Figure 4 As shown, the guide buffer assembly 500 includes:

[0104] A second guide groove 510 is disposed in the guide groove 122;

[0105] The first slider 520 is connected to one end of the barrel 422 away from the first spring 430 and is slidably disposed in the second guide groove 510;

[0106] The second slider 530 is disposed in the second guide groove 510 and is hinged to the first slider 520;

[0107] a second spring 540, one end of which is connected to the second slider 530, and the other end of which is connected to the top of the second guide groove 510;

[0108] The first sliding block 520 is provided with a through hole 521 for the second spring 540 to pass through.

[0109] In the embodiment of the present application, the second guide groove 510 is arranged in the guide groove 122, providing a limited movement space for the first slider 520 and the second slider 530, ensuring the stability and accuracy of the slider during the sliding process. The first slider 520 is connected to one end of the barrel 422 away from the first spring 430, and is slidably arranged in the second guide groove 510. When the barrel 422 slides in the first guide groove 410, the first slider 520 will slide in the second guide groove 510 accordingly. The second slider 530 is arranged in the second guide groove 510 and is connected to the first slider 520 by a hinged manner. This connection mode enables the second slider 530 to change the angle between the first slider 520 and the second slider 520, which is convenient for the first slider 520 to cooperate with the second guide groove 510. One end of the second spring 540 is connected to the second slider 530, and the other end is connected to the top of the second guide groove 510. When the first slider 520 and the second slider 530 slide in the second guide groove 510, the second spring 540 will expand and contract, thereby further absorbing shock and vibration. The first slider 520 is provided with a through hole 521 for the second spring 540 to pass through, which ensures that the second spring 540 can be correctly connected to the first slider 520 and the second slider 530 and play its buffering role.

[0110] Through the close cooperation of the first slider 520, the second slider 530 and the second spring 540, the guide buffer assembly 500 can further enhance the buffering effect of the sliding buffer structure 400. When the clamping device 200 moves, the second spring 540 will expand and contract, thereby absorbing the energy generated during the movement and improving the stability of the device. At the same time, the angle change of the second slider 530 relative to the first slider 520 enables the guide buffer assembly 500 to better adapt to the change of the path of the second guide groove 510 during the sliding process, thereby improving the stability of the adjustment.

[0111] Embodiment 6:

[0112] An embodiment of the present application provides a device for non-destructive testing of boiler tube panel welded joints. In addition to the above-mentioned technical features, the device for non-destructive testing of boiler tube panel welded joints in the embodiment of the present application also includes the following technical features.

[0113] like Figure 3 and Figure 4As shown, the second guide groove 510 includes a guide section 511 and a limit section 512 , the guide section 511 is arranged straight, the limit section 512 is arc-shaped, and the second sliding block 530 cooperates with the limit section 512 and can slide into the limit section 512 .

[0114] In the embodiment of the present application, the guide section 511 is arranged straightly to provide a stable sliding path for the first slider 520 and the second slider 530. When the clamping device 200 moves normally, the slider mainly slides in the guide section 511. The limiting section 512 is arc-shaped and connected to the guide section 511. When the second slider 530 slides to the end of the guide section 511, it will enter the limiting section 512, which is intended to limit its further movement by changing the moving direction of the slider and provide an additional buffering effect. The second slider 530 is designed to cooperate with the limiting section 512 and slide into the limiting section 512 during the sliding process. When the slider enters the limiting section 512, its moving direction will change, thereby limiting the further movement of the clamping device 200.

[0115] By setting the limiting section 512, when the slider slides to the end of the guide section 511, it will enter the limiting section 512 and be restricted by it, which can prevent the clamping device 200 from continuing to move downward in unexpected situations such as the breakage of the pull rope 340, thereby protecting the safety of equipment and personnel. At the same time, the arc-shaped design of the limiting section 512 enables the slider to change the direction of movement when sliding in, thereby dispersing the force during the downward movement in the arc direction. The dispersion effect can reduce the impact on equipment and personnel and improve the buffering effect. In unexpected situations such as the breakage of the pull rope 340, the clamping device 200 and the flaw detector may move downward rapidly due to loss of support. The present application can slow down the downward movement speed and reduce the impact force by setting the limiting section 512 and dispersing the impact force, thereby improving the safety of equipment and personnel.

[0116] Furthermore, first sliding protrusions 550 are provided on both sides of the first sliding block 520 and the second sliding block 530 . The cross section of the first sliding protrusion 550 is circular. A first limiting sliding groove 560 cooperating with the first sliding protrusion 550 is provided on the side wall of the second guide groove 510 .

[0117] In some embodiments of the present application, the first slider 520 is connected to the barrel 422, and the second slider 530 is hinged to the first slider 520, and the two slide together in the second guide groove 510, ensuring the stability and accuracy of the slider during the sliding process. The first slider 520 and the second slider 530 are both provided with first sliding protrusions 550 on both sides, and the cross-sections of these protrusions are circular. The circular cross-section design enables the sliding protrusions to better adapt to the shape of the first limiting slide groove 560 during the sliding process, reducing friction and wear.

[0118] The side wall of the second guide groove 510 is provided with a first limiting slide groove 560 that cooperates with the first sliding protrusion 550. The shape and size of these slide grooves match the first sliding protrusion 550, ensuring the stability and accuracy of the slider during the sliding process. The cooperation between the first sliding protrusion 550 and the first limiting slide groove 560 enables the slider to remain stable during the sliding process, and is not prone to displacement or shaking, which helps to improve the overall stability and accuracy of the device. At the same time, the first sliding protrusion 550 with a circular cross-section can better adapt to the shape of the first limiting slide groove 560, thereby reducing friction and wear during the sliding process, helping to extend the service life of the device and reduce maintenance costs. In addition, the design of the first limiting slide groove 560 provides a clear sliding path for the slider, enhances the guiding property, helps the movement of the first slider 520 and the second slider 530, and improves reliability.

[0119] Embodiment 7:

[0120] An embodiment of the present application provides a device for non-destructive testing of boiler tube panel welded joints. In addition to the above-mentioned technical features, the device for non-destructive testing of boiler tube panel welded joints in the embodiment of the present application also includes the following technical features.

[0121] like Figure 5 As shown, a second limiting sliding groove 570 adapted to the barrel portion 422 is further provided in the first guide groove 410 , and a second sliding protrusion 580 adapted to the second limiting sliding groove 570 is provided on the barrel portion 422 .

[0122] In the embodiment of the present application, the second limiting slide groove 570 is arranged in the first guide groove 410, and its shape and size match the second sliding protrusion 580 on the barrel 422, which can ensure the stability and accuracy of the barrel 422 when sliding in the first guide groove 410. The second sliding protrusion 580 is arranged on the outer surface of the barrel 422 and is adapted to the second limiting slide groove 570. When the barrel 422 slides in the first guide groove 410, the second sliding protrusion 580 will be closely matched with the second limiting slide groove 570, which not only ensures the stable sliding of the barrel 422, but also prevents the barrel 422 from deflecting or shaking during the sliding process, which helps to improve the overall stability and accuracy of the sliding buffer structure 400.
