Description

Technical Field

[0001] The invention relates to the technical field of stress detection devices, and in particular to a residual stress detection device for processing and manufacturing a steel box truss arch bridge steel structure. Background Art

[0002] The steel box truss arch bridge is composed of a steel box girder and a truss structure. This combined structure enables the bridge to have the advantages of high rigidity and small deformation of the steel box girder, as well as the characteristics of reasonable force and high material utilization of the truss structure.

[0003] The arch rib is the skeleton of the main arch ring of the arch bridge, and is responsible for transferring the load to the arch seat and other supporting structures. During the construction and use of the arch bridge, the arch rib needs to bear multiple forces such as its own weight, bridge deck load, wind load, temperature stress, etc. Therefore, its stress state is one of the key indicators for evaluating the performance of the arch bridge.

[0004] During the welding process of the arch rib, the weldment will be subjected to uneven local heating and cooling, resulting in welding residual stress inside the weldment. This residual stress is the main factor causing cracks and deformation in welded components, and has a great impact on the welding quality. Welding residual stress not only exists in the weld area, but may also extend to the surrounding materials, affecting the overall structural performance; therefore, after the welding is completed, it is necessary to detect the stress on its surface to understand the size and distribution of the welding residual stress, and provide a basis for subsequent construction adjustments and reinforcement measures; however, after the arch rib welding is completed, during the inspection process, there is a large amount of welding slag on the surface of the weld, which affects the inspection effect, and the existing welding slag cleaning device has a poor cleaning effect.

[0005] For example, the ultrasonic detection device and method for residual stress of steel structure welds provided by authorization announcement No. CN117824896B continuously squeezes the reciprocating disk under the rotation of the eccentric block in the device, so that the reciprocating disk drives the bump rod to move back and forth left and right, causing the spring damper to deform, thereby causing the frame to vibrate, shaking off the moisture and welding slag on the surface of the steel plate, so that the water flow and welding slag can quickly fall to the upper end of the workbench, and the welding slag attached to the surface of the steel plate is cleaned.

[0006] It has major drawbacks: the reciprocating disk is sleeved on the lug rod, and when the reciprocating disk is resisted by the eccentric wheel, it cannot drive the lug rod to move back and forth, and can only make the reciprocating disk move back and forth on the lug rod, and the vibration effect is poor, almost non-existent; at the same time, the connection structure in the prior art is complicated, and the eccentric wheel can only rotate when the steel plate rotates, and the vibration effect is poor. Vibration can only be generated while rotating, and it cannot be controlled separately. Summary of the invention

[0007] The embodiment of the present application provides a residual stress detection device for processing and manufacturing steel structures of steel box truss arch bridges, thereby solving the problem in the prior art that a reciprocating disk is sleeved on a lug rod, and when the reciprocating disk is resisted by an eccentric wheel, it cannot drive the lug rod to move back and forth, and can only make the reciprocating disk move back and forth on the lug rod, resulting in a poor vibration effect, or almost no vibration. At the same time, the connection structure in the prior art is complicated, and the eccentric wheel can only rotate when the steel plate rotates, resulting in a poor vibration effect, and vibration can only be generated while rotating, and cannot be controlled independently, thereby achieving an improved vibration effect, thereby improving the cleaning effect, and fixing the reciprocating plate on a telescopic rod, and when the reciprocating plate moves, it can drive the telescopic rod to move together, and the complicated connection mechanism is deleted for independent control, and each structure can be controlled independently, thereby improving the vibration effect on the steel plate.

[0058] Thirdly, after the elastic member is deformed, the iron ball hits the reciprocating plate through the elastic force after the elastic member is reset.

[0059] Fourthly, the elastic membrane is changed into an airbag structure, and there are multiple airbag structures, each of which is controlled individually and corresponds to multiple iron balls one by one. The inflation amount in different elastic membranes can be controlled to be different, thereby changing the impact force on the reciprocating plate. Through vibrations of different frequencies and rates, the cleaning effect of different welding slag on different steel plates can be improved. At the same time, by controlling the expansion of the elastic membrane alone, in the process of one rotation of the vibration block, it can resist the reciprocating plate to make it reach a farther place, increase the initial force, and improve the vibration cleaning effect.

[0097] One end of the delivery pipe 230 away from the spray plate 220 passes through the bracket 2 150 and is fixed on the output end of the water pump 120. The delivery pipe 230 is made of rubber.

[0098] The adjustment assembly 700 includes a telescopic cylinder 1 710, a motor 1 720 and a telescopic rod 2 730;

[0099] The telescopic cylinder 1 710 is fixed on one side of the bracket 2 150 close to the bracket 1 130;

[0100] There are two telescopic rods 730, one end of which is fixed to the end of the telescopic cylinder 710 away from the bracket 150, and the motor 720 is fixed to the end of the telescopic rod 730 away from the telescopic cylinder 710;

[0101] The extension direction of the second telescopic rod 730 is parallel to the ground, and the rotation axis of the first motor 720 is parallel to the extension direction of the second telescopic rod 730;

[0102] The clamping assembly 300 includes a vertical plate 310, a fixed plate 320 and a clamping cylinder 330;

[0103] There are two fixing plates 320, which are symmetrically fixed on one side of the vertical plate 310, and the clamping cylinder 330 is fixed on the lower side of the fixing plate 320 located above;

[0104] One side of the inner plate 310 of one clamping assembly 300 away from the fixed plate 320 is rotatably connected to one end of the telescopic rod 1 410 away from the bracket 1 130, and the other side of the inner plate 310 of the other clamping assembly 300 away from the fixed plate 320 is fixed away from the output end of the motor 1 720;

[0105] The lower sides of the vertical plates 310 in the two clamping assemblies 300 are on the same horizontal plane, and the upper sides of the vertical plates 310 in the two clamping assemblies 300 are on the same horizontal plane;

[0106] The vibration assembly 500 includes a connecting plate 510, a second motor 520 and a vibration block 530;

[0107] The connecting plate 510 is fixed to one side of the bracket 130 close to the bracket 2 150 , the connecting plate 510 is located above the telescopic rod 1 410 , the motor 2 520 is fixed to one side of the connecting plate 510 , and the vibration block 530 is fixed to the output end of the motor 2 520 ;

[0108] When the motor 2 520 drives the vibration block 530 to rotate, the vibration block 530 can contact the side of the reciprocating plate 420 close to the bracket 1 130;

[0109] The detection assembly 600 includes an electric slide 2 610, a telescopic cylinder 2 620, a telescopic cylinder 3 630 and an ultrasonic probe 640;

[0110] The second electric slide 610 is fixed to the upper side of the support plate 110, the lower end of the second telescopic cylinder 620 is fixed to the slider of the second electric slide 610, the third telescopic cylinder 630 is fixed to the upper end of the second telescopic cylinder 620, and the ultrasonic probe 640 is fixed to one end of the third telescopic cylinder 630;

[0111] The telescopic direction of the telescopic cylinder 3 630 is parallel to the ground, the telescopic direction of the telescopic cylinder 2 620 is perpendicular to the ground, and the detection direction of the ultrasonic probe 640 is downward.

[0112] When in use, the position of the steel plate to be inspected is fixed by two clamping assemblies 300, and clamped by the clamping cylinder 330. The position between the two clamping assemblies 300 can be adjusted by the extension and retraction of the telescopic cylinder 710 to adapt to a larger steel plate size. Before the inspection, the water in the cavity of the support plate 110 is pumped out by turning on the water pump 120, and sprayed out through the nozzle on the lower side of the spray plate 220 to clean the welding part of the steel plate. At the same time, the spray plate 220 can adjust its position through the electric slide 210 to comprehensively clean the steel plate. During the cleaning process, the vibration block 530 is driven to rotate by the motor 520. During the rotation, the vibration block 530 contacts the reciprocating plate 420, causing the position of the reciprocating plate 420 to change. When the vibration block 530 no longer contacts the reciprocating plate 420, it is reset through the spring damper 430, and vibration is generated during the resetting process to clean the welding slag attached to the surface of the steel plate. During the cleaning process, the clamped steel plate can also be driven to rotate together through the motor 720 to tilt the steel plate and slide the welding slag on its surface. After the cleaning is completed, the welded weld is detected by the ultrasonic probe 640. The position of the ultrasonic probe 640 can be adjusted by the electric slide 2 610, the telescopic cylinder 2 620 and the telescopic cylinder 3 630 to detect welds at different positions. The water used for cleaning can be reused by filtering through the filter at the water inlet 111. After long-term use, it can be cleaned by removing the filter at the water inlet 111.

[0113] Compared with the prior art, during use, the vibration effect generated is improved, thereby improving the cleaning effect, so that the reciprocating plate 420 is fixed on the telescopic rod 410. When the reciprocating plate 420 moves, the telescopic rod 410 can be driven to move together, and the cumbersome connection mechanism is deleted for individual control. Each structure can be controlled individually, thereby improving the vibration effect on the steel plate.

[0114] Embodiment 2: When the embodiment 1 is in use, the vibration block 530 rotates to resist the reciprocating plate 420, changing the position of the reciprocating plate 420, so that vibration is generated during the resetting process of the reciprocating plate 420, and the welding slag attached to the surface of the steel plate is cleaned. However, during the resetting process of the reciprocating plate 420, the vibration block 530 is hit, resulting in the cessation of reciprocating vibration, resulting in a poor vibration effect. Based on this, the solution of the embodiment 1 is improved, such as Figure 4-Figure 6 As shown:

[0115] The rotation axis of the second motor 520 is parallel to the ground, and the axis of the second motor 520 is perpendicular to the extension direction of the telescopic rod 1 410. The vibration block 530 is in the shape of a half cylinder divided along its axis, and the cross section of the vibration block 530 is semicircular.

[0116] When the second motor 520 drives the vibration block 530 to rotate, the arc surface of the vibration block 530 contacts the reciprocating plate 420 .

[0117] During use, since the cross-section of the vibration block 530 is semicircular, the length of the spring damper 430 is continuously stretched in the process of the arc surface contacting the reciprocating plate 420. When there is no contact, the spring damper 430 is reset by the elastic force of the spring damper 430. During the reset process, vibration is generated to perform cleaning.

[0118] The position of the vibration block 530 is adjusted so that its rotation axis changes from perpendicular to the ground to parallel to the ground, and its shape is changed to a semicircle; after it rotates and contacts the reciprocating plate 420, with the plane facing downward, the reciprocating plate 420 will not hit the vibration block 530 during the rebound process and will not be intercepted by the vibration block 530, thereby improving the vibration effect and thus improving the cleaning effect of the welding slag on the surface of the steel plate.

[0119] Embodiment 3: When the embodiment 2 is in use, the reciprocating plate 420 is driven to move by the vibration block 530, and then reset by the elastic force of the spring damper 430. However, during use, the vibration cleaning effect generated is poor. Based on this, the solution of the embodiment 2 is improved, such as Figure 7 As shown:

[0120] The vibration assembly 500 further includes a groove 531, an elastic member 540, an iron ball 550 and an electromagnet 560;

[0121] The arc surface of the vibration block 530 is provided with a groove 531, and the electromagnet 560 is fixed in the groove 531;

[0122] The elastic member 540 is fixed at the opening of the groove 531 , and the iron ball 550 is fixed on the elastic member 540 ;

[0123] There are a plurality of iron balls 550 , which are evenly spaced and distributed.

[0124] When the vibration block 530 contacts the reciprocating plate 420 through its own arc surface, the electromagnet 560 is intermittently powered on and off. When the electromagnet 560 is powered on, the iron ball 550 is affected by the magnetic force and moves inward, causing the elastic member 540 to deform. When the electromagnet 560 is powered off, the iron ball 550 hits the reciprocating plate 420, causing the reciprocating plate 420 to vibrate. During the intermittent on and off of the electromagnet 560, multiple hits and knocks are performed.

[0125] After the elastic member 540 is deformed, the iron ball 550 hits the reciprocating plate 420 through the elastic force of the elastic member 540 after it is reset. Multiple impacts can cause the reciprocating plate 420 to vibrate multiple times. During the process of the vibration block 530 rotating one circle, the vibration effect of the steel plate is improved, thereby improving the cleaning efficiency of the welding slag attached to the surface of the steel plate.

[0126] Embodiment 4: During the use of embodiment 3, the iron ball 550 impacts the reciprocating plate 420 to generate vibration, and the welding slag attached to the surface of the steel plate is cleaned. However, when the device is in use, the vibration effect of the device on the steel plate can be further improved to improve the cleaning efficiency of the steel plate. Based on this, the solution of embodiment 3 is improved, such as Figure 8-Figure 9 As shown:

[0127] The vibration assembly 500 further includes an elastic membrane 541 and an air pump member 570;

[0128] There are multiple elastic membranes 541, and the multiple elastic membranes 541 are connected to each other to form an elastic member 540;

[0129] The elastic membrane 541 is fixed in the opening of the groove 531 . The number of the elastic membranes 541 is consistent with the number of the iron balls 550 , and they correspond one to one. The iron balls 550 are fixed on the elastic membranes 541 .

[0130] The elastic membrane 541 is hollow inside and has an airbag structure;

[0131] The air pump component 570 is fixed on a side of the vibration block 530 away from the motor 2 520 . The air pump component 570 has an air pump inside. The number of the air pumps is consistent with the number of the elastic membranes 541 and corresponds one to one. The output end of the air pump is connected to the elastic membrane 541 .

[0132] During use of the device, the air pump in the air pump component 570 can be controlled to fill different amounts of air into the elastic membrane 541 at different positions to make it expand differently. After the electromagnet 560 adsorbs the iron ball 550 and the power is cut off, the iron ball 550 can produce different impact forces when it hits the reciprocating plate 420. At the same time, the elastic membrane 541 can be expanded alone, and during a rotation of the vibration block 530, it can resist the reciprocating plate 420 to make it reach a farther place, thereby increasing the initial force.

[0133] The elastic membrane 541 is transformed into an airbag structure, and there are multiple ones, each of which is controlled separately and corresponds to the multiple iron balls 550 one by one. The inflation amount in different elastic membranes 541 can be controlled to be different, so as to change the impact force on the reciprocating plate 420. By vibrating with different frequencies and rates, the cleaning effect of different welding slag on different steel plates can be improved. At the same time, by controlling the expansion of the elastic membrane 541 separately, in the process of rotating the vibration block 530 once, it can resist the reciprocating plate 420 to make it reach a farther place, increase the initial force, and improve the vibration cleaning effect.

[0134] Taking the inspection of a steel plate with a length and width of one meter and a thickness of four centimeters as an example, the steel plate is fixed by the clamping assembly 300 in the above-mentioned device, and cleaning water is sprayed by the cleaning assembly 200. The vibration block 530 in the vibration assembly 500 contacts the reciprocating plate 420. While contacting, the electromagnet 560, the iron ball 550 and the elastic membrane 541 can also produce a vibration effect, which significantly improves the vibration efficiency and cleaning uniformity; at the same time, under the inflation effect of the elastic membrane 541, the reciprocating plate 420 obtains a greater initial force, produces a stronger vibration effect, and further improves the cleaning efficiency; under the same conditions, the improved device can improve the efficiency of about 20%-30% when cleaning steel plates of the same size compared to the existing device, thereby improving the vibration effect and the cleaning effect, and making it easier to flush and clean the welding slag.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
