Description

Technical Field

[0001] The invention relates to the technical field of weld detection, and in particular to a cross weld detection device for a bridge steel structure. Background Art

[0002] Highway routes pass through rivers, harbors, lakes, reservoirs, irrigation canals and other water bodies, or cross deep valleys with large elevation differences, or cross other traffic routes. In order to keep traffic smooth, bridges need to be built. In the production of welded structures, the quality of welds obtained by the current welding technology has not yet achieved sufficient stability. Therefore, in order to ensure the quality of welded components, welds must be inspected to ensure that they meet the specified technical requirements and the safe use of the structure. Nondestructive testing of welds refers to the use of ultrasonic testing, magnetic particle testing or penetrant testing to inspect whether the quality of welds meets the specified requirements and design intent without damaging the performance and integrity of the welds being inspected.

[0003] After searching, the patent with patent announcement number CN202021151057.9 discloses a cross-intersecting weld detection device for a highway bridge steel structure. Although the device is used by winding the wire 5 around the winding wheel 41 for one circle, holding the handle 43, driving the winding wheel 41 to rotate forward, winding the remaining wire 5 around the winding wheel 41, and then hanging the L-shaped rod 45 on one side of the detection probe 3 in the through hole 46 on the fixing plate 44, thereby fixing the detection probe 3 on the weld detection body 1, when performing the detection, the L-shaped rod 45 on the detection probe 3 is taken out from the through hole 46 of the fixing plate 44, holding the handle 43, and driving the winding wheel 41 to rotate forward, and winding the remaining wire 5 around the winding wheel 41, and then hanging the L-shaped rod 45 on one side of the detection probe 3 in the through hole 46 on the fixing plate 44, thereby fixing the detection probe 3 on the weld detection body 1, when performing the detection, the L-shaped rod 45 on the detection probe 3 is taken out from the through hole 46 of the fixing plate 44, and holding the handle 43. Handle 43, rotate the winding wheel 41 in the opposite direction, and lengthen the wire 5. The weld detection body 1 is supported and placed by the support frame 10. When the weld detection body 1 is working, heat is dissipated through the heat dissipation holes 7. The dustproof net 9 prevents dust from entering the weld detection body 1 through the heat dissipation holes 7. The bolts 8 next to the dustproof net 9 are unscrewed, and the dustproof net 9 can be disassembled and cleaned. However, when the device is used, when the defective position is detected, it is also necessary to mark the defective part through other equipment or devices, which not only increases the complexity of the operation, but also may reduce the detection efficiency, because it is necessary to frequently switch or carry additional marking tools during the detection process. And the display screen and the control interface are directly exposed to the outside, lacking the necessary protection. During transportation or carrying, these vulnerable parts are easily hit, scratched or contaminated, resulting in equipment damage or functional failure. This not only increases the maintenance cost, but also may affect the accuracy and reliability of the detection. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a device for detecting cross welds of a bridge steel structure, which solves the problems raised in the background art.

[0005] The solution of the present invention to solve the above technical problems is as follows:

[0006] A cross weld detection device for a bridge steel structure comprises a body, an upper cover is rotatably mounted on the body through a damping hinge, an ultrasonic probe is connected to the body through a cable, and a base is mounted on the bottom end of the body;

[0007] The machine body is provided with a control panel, the back of the machine body is provided with a wiring board, the cable is connected to the machine body signal through the wiring board, a reel is installed at one end of the cable away from the machine body, the ultrasonic probe is located on the reel, and the cable passes through the reel to be connected to the ultrasonic probe signal;

[0008] The base is provided with side plates and a containing box, wherein the side plates are symmetrically distributed on both sides of the containing box, and a marking module is installed in the containing box, wherein the marking module is evenly distributed in the containing box, and the marking module irradiates and marks the detected defect positions.

[0009] Based on the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, a handle is installed at one end of the body away from the wiring board, and the body is carried by the handle.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] The handle design makes the entire device easier to carry and move. Users can easily transfer the detection device from one work site to another by holding the handle, especially when on-site testing or multiple tests in different locations are required. Lifting or carrying the body directly may increase the risk of it being hit or damaged. The handle design provides a dedicated, more stable grip point, helping to reduce damage caused by accidental drops or collisions during carrying or moving.

[0013] Furthermore, the base is connected and fixed to the body by bolts, sliders are provided on both sides of the accommodating box, and sliding grooves are provided on the side plates. The accommodating box is slidably installed between the side plates by means of the sliders and the sliding grooves.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] The base is fixed to the body by bolts. This connection method is relatively tight and can effectively ensure the stability and firmness between the body and the base. Bolt connection is not only high in strength, but also has certain earthquake and impact resistance, and can adapt to complex and changeable working environments. Compared with other fixing methods such as welding, bolt connection can be easily installed and disassembled. This makes it possible to complete related operations more quickly and efficiently when repairs, replacement of parts or adjustment of equipment layout are required, reducing maintenance costs and time costs. The storage box is installed between the side panels through sliders and slide grooves. This design allows the position of the storage box to be adjusted within a certain range. This provides users with greater flexibility and allows them to adjust the position of the storage box according to actual work needs in order to better place or remove items (such as marking modules, etc.)

[0016] Furthermore, the receiving box is inlaid with a second magnet, and the side plate is inlaid with a first magnet. After the receiving box slides into place, the second magnet and the first magnet are adsorbed and fixed between the two side plates.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The adsorption force between the magnets can provide a strong fixing effect, ensuring that the container box can be tightly fixed between the two side panels after sliding into place, and is not prone to shaking or displacement. This fixing method is more stable and reliable than traditional mechanical locking or snap fixing. The magnet adsorption fixing method allows users to fix and release the container box without using additional tools or operations. The user only needs to slide the container box to the specified position, and the magnet will automatically adsorb and fix the container box; when the container box needs to be released, only a certain external force needs to be applied to overcome the adsorption force of the magnet, which is very convenient to operate. Compared with traditional mechanical locking or snap fixing methods, the magnet adsorption fixing method will not cause wear or damage. Because the adsorption force between the magnets is achieved through the action of the magnetic field, the fixing effect can be achieved without physical contact, so it will not cause wear or damage to the container box or the side panels.

[0019] Furthermore, a damping rod is provided in the base, and the marking module is provided with a rotating seat, which is rotatably mounted on the damping rod, and a plastic bent pipe is connected to the rotating seat, and a laser indicator is installed at one end of the plastic bent pipe away from the rotating seat.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] The rotating seat is rotatably mounted on the damping rod, which makes the laser pointer more flexible. Users can adjust the direction and angle of the laser pointer according to actual detection needs to more accurately mark the defect location in the weld. At the same time, this design also improves the adaptability of the equipment to different working environments and detection requirements. The design of the shapeable elbow allows users to adjust the position and posture of the laser pointer as needed. The elbow has a certain flexibility and plasticity and can be bent or twisted to adapt to specific spatial layouts or detection needs. This design not only improves the flexibility of the equipment, but also makes it easier for the laser pointer to reach hard-to-reach areas. The laser pointer uses a high-precision beam to illuminate and mark the defect location in the weld with extremely high accuracy. Combined with the design of the shapeable elbow and the rotating seat, users can ensure that the laser beam accurately points to the defect location, improving detection efficiency and accuracy. By integrating the damping rod, rotating seat, shapeable elbow and laser pointer together, the design achieves a compact structure and efficient use of space. This not only reduces the overall size and weight of the equipment, but also makes the equipment easier to carry and install. At the same time, the compact structure also helps to improve the stability and reliability of the equipment.

[0022] Furthermore, a spring winding wheel is rotatably installed in the reel through a clockwork spring, and the cable is evenly wound around the spring winding wheel in the reel.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] The spring provides the power for the spring reel to automatically rewind. When the cable is released for testing or other purposes, the spring automatically drives the spring reel to rotate and wind the cable back evenly without manual operation. This automation function greatly improves work efficiency and reduces the tediousness of manual operation. Since the cable is evenly wound on the spring reel in the reel, there will be no problems such as cable knotting and random winding. This not only makes the cable release and rewinding process smoother, but also facilitates the user to pick up and organize during use. Through automatic rewinding and even winding, the cables are stored and managed in an orderly manner in the reel. This avoids the wear and aging of the cables caused by long-term disorderly stacking, thereby extending the service life of the cables.

[0025] Furthermore, a handle is installed in the reel, and a lower pressure plate is provided in the reel. An upper pressure plate is provided above the lower pressure plate in the reel, and a spring is provided between the upper pressure plate and the lower pressure plate, and the handle is elastically supported by the spring.

[0026] The beneficial effects of adopting the above further scheme are:

[0027] The handle design allows users to operate the reel more conveniently. Through the handle, users can easily control the reeling and releasing actions without directly touching or operating other components inside the reel. This design improves the convenience of operation and allows users to complete the reeling and releasing of the cable more quickly. The handle, lower pressure plate, upper pressure plate and spring are integrated inside the reel to achieve a compact structure and efficient use of space. This design not only reduces the overall size and weight of the reel, but also makes the reel easier to carry and install. At the same time, the compact structure also helps to improve the stability and reliability of the reel.

[0028] Furthermore, a through hole is formed on the lower pressing plate, the cable passes through the through hole of the lower pressing plate, and the lower pressing plate is pressed and fixed by a spring.

[0029] The beneficial effects of adopting the above further scheme are:

[0030] The lower pressure plate uses the spring to press down on the cable to fix it. This fixing method can ensure that the cable remains stable in the reel and is not easy to loosen or fall off. The elastic force of the spring provides continuous pressing force, so that the cable can maintain a stable position during the reeling and releasing process. Due to the use of the spring-down pressing and fixing method, the user can quickly fix the cable in the reel without using additional tools or performing complicated operations. Similarly, when the cable needs to be released, it is only necessary to simply release the pressing state of the lower pressure plate, which is very convenient to operate.

[0031] Furthermore, a power interface is provided on one side end surface of the body, the body is connected to an external power source through the power interface, and the laser pointer is electrically connected to a wiring board through a power line, and the laser pointer is powered through the wiring board of the body.

[0032] The beneficial effects of adopting the above further scheme are:

[0033] This design connects the body to an external power source through a power interface, ensuring that the laser pointer can obtain a stable and reliable power supply. This stable power supply environment helps the laser pointer maintain normal working conditions and improves the stability and reliability of the device. External power supplies usually have high stability and reliability and can provide stable voltage and current for the laser pointer. This helps reduce the impact of power fluctuations on the laser pointer and ensure the normal operation of the device.

[0034] The present invention provides a cross weld detection device for a bridge steel structure.

[0035] Beneficial effects:

[0036] The device is designed with a handle for easy carrying and movement, making the inspection work more flexible and convenient. The upper cover is connected to the body through a damping hinge, which not only protects the internal equipment but also facilitates opening for maintenance and operation.

[0037] The ultrasonic probe is connected to the machine body through a cable, which is used to accurately detect the quality of the weld, improving the accuracy and efficiency of the detection. The reel is equipped with a spring reel that can automatically reel the cable, avoiding confusion and loss of the cable, and also facilitating the pulling and reeling of the cable. The design of the grip allows the user to easily control the retraction and release of the cable, further improving the convenience of operation.

[0038] The base is fixedly connected to the body by bolts, providing a stable support platform and ensuring the stability of the detection process. The receiving box slides between the side panels through the slider and the slide groove, and is fixed to each other by the second magnet and the first magnet. This design not only ensures the stability of the receiving box, but also facilitates the adjustment of its position. The setting of the marking module enables the detected defect position to be accurately marked, improving the intuitiveness and traceability of the detection results.

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] See also Figures 1 to 7 As shown, the embodiments provided by the present invention are:

[0052] Embodiment 1

[0053] A cross weld detection device for a bridge steel structure includes a body 7, an upper cover 5 is rotatably mounted on the body 7 via a damping hinge 4, an ultrasonic probe 1 is connected to the body 7 via a cable 3, a base 8 is mounted on the bottom end of the body 7, a handle 6 is mounted on the end of the body 7 away from the wiring board 702, the body 7 is carried by the handle 6, and the design of the handle 6 makes the entire device easier to carry and move. The user can easily transfer the detection device from one work site to another by holding the handle 6, especially when on-site detection or multiple detections at different locations are required. Directly lifting or carrying the body 7 may increase the risk of it being hit or damaged. The design of the handle 6 provides a dedicated, more stable gripping point, which helps to reduce damage caused by accidental drops or collisions during carrying or moving.

[0054] Embodiment 2

[0055] In order to facilitate the stretching or winding of the cable 3, for example, Figures 1 to 5As shown, the present invention also includes: a control panel 701 is provided on the body 7, a wiring board 702 is provided on the back of the body 7, the cable 3 is connected to the body 7 by signal through the wiring board 702, a reel 2 is installed at the end of the cable 3 away from the body 7, the ultrasonic probe 1 is located on the reel 2, the cable 3 passes through the reel 2 and is connected to the ultrasonic probe 1 by signal, a spring reel 204 is installed in the reel 2 through the rotation of the spring spring, the cable 3 is evenly wound on the spring reel 204 in the reel 2, and the spring spring 202 provides the spring reel 204 with power for automatic reeling. When the cable 3 is released for detection or other purposes, the spring spring 202 will automatically drive the spring reel 204 to rotate and evenly wind the cable 3 back without manual operation. This automatic function greatly improves work efficiency and reduces the tediousness of manual operation. Since the cable 3 is evenly wound on the spring reel 204 in the reel 2, there will be no problems such as the cable 3 being knotted or wound randomly. This not only makes the cable 3 smoother during the release and reeling process, but also facilitates the user to take, place and organize during use. Through the automatic reeling and uniform winding method, the cable 3 is stored and managed in an orderly manner in the reel 2. This avoids the wear and aging of the cable 3 caused by long-term disorderly stacking, thereby extending the service life of the cable 3. A grip 205 is installed in the reel 2. The grip 205 is located in the reel 2 and a lower pressure plate 203 is provided. The reel 2 is provided with an upper pressure plate 201 above the lower pressure plate 203. A spring 202 is provided between the upper pressure plate 201 and the lower pressure plate 203. The grip 205 is elastically supported by the spring 202. The design of the grip 205 allows the user to operate the reel 2 more conveniently. Through the grip 205, the user can easily control the reeling and releasing actions of the reel 2 without directly touching or operating other components in the reel 2. This design improves the convenience of operation, allowing the user to complete the reeling and releasing of the cable 3 more quickly. The components such as the handle 205, the lower pressure plate 203, the upper pressure plate 201 and the spring 202 are integrated inside the reel 2, achieving a compact structure and efficient use of space. This design not only reduces the overall volume and weight of the reel 2, but also makes the reel 2 easier to carry and install. At the same time, the compact structure also helps to improve the stability and reliability of the reel 2. A through hole is provided on the lower pressure plate 203, and the cable 3 passes through the through hole of the lower pressure plate 203. The lower pressure plate 203 is pressed down by the spring to press and fix the cable 3. When the cable 3 needs to be reeled, the user holds the reel 2 and presses the handle 205. The handle 205 compresses the spring 202 and then loosens the cable 3, thereby facilitating the pulling or reeling of the cable 3. The lower pressure plate 203 is pressed down by the spring 202 to press and fix the cable 3. This fixing method can ensure that the cable 3 remains stable in the reel 2 and is not easy to loosen or fall off. The elastic force of the spring 202 provides a continuous pressing force, so that the cable 3 can maintain a stable position during the winding and releasing processes.Since the spring 202 is used to press and fix the cable 3, the user can quickly fix the cable 3 in the reel 2 without using additional tools or performing complicated operations. Similarly, when the cable 3 needs to be released, it is only necessary to simply release the pressing state of the lower pressing plate 203, which is very convenient.

[0056] Embodiment 3

[0057] In order to facilitate the irradiation marking of the detected defect position, for example, Figures 1 to 7As shown, the present invention also includes: the base 8 is connected and fixed with the body 7 by bolts, sliders 803 are provided on both sides of the containing box 806, and a slide groove 801 is provided on the side plate 805, and the containing box 806 is installed between the side plates 805 by limiting the sliding of the slider 803 and the slide groove 801, and the base 8 is connected and fixed with the body 7 by bolts. This connection method is relatively tight, and can effectively ensure the stability and firmness between the body 7 and the base 8. The bolt connection is not only high in strength, but also has certain seismic and impact resistance, and can adapt to complex and changeable working environments. Compared with other fixing methods such as welding, the bolt connection can be easily installed and disassembled. This makes it possible to complete the relevant operations more quickly and efficiently when it is necessary to repair, replace parts or adjust the equipment layout, reducing maintenance costs and time costs. The containing box 806 is installed between the side plates 805 by limiting the sliding of the slider 803 and the slide groove 801. This design allows the position of the containing box 806 to be adjusted within a certain range. This provides users with greater flexibility, and the position of the container box 806 can be adjusted according to actual work needs, so as to better place or take out the items therein (such as the marking module 9, etc.). The container box 806 is inlaid with a second magnet 804, and the side plate 805 is inlaid with a first magnet 802. After the container box 806 slides into place, the second magnet 804 and the first magnet 802 are mutually adsorbed and fixed between the two side plates 805. The adsorption force between the magnets can provide a strong fixing effect, ensuring that the container box 806 can be tightly fixed between the two side plates 805 after sliding into place, and it is not easy to shake or move. This fixing method is more stable and reliable than traditional mechanical locking or snap fixing. The magnet adsorption fixing method allows users to fix and release the container box 806 without using additional tools or operations. The user only needs to slide the container box 806 to the specified position, and the magnet will automatically adsorb and fix the container box 806; when the container box 806 needs to be released, it only needs to apply a certain external force to overcome the adsorption force of the magnet, and the operation is very convenient. Compared with the traditional mechanical locking or snap-on fixing method, the magnet adsorption fixing method will not cause the problem of wear or damage. Because the adsorption force between the magnets is achieved through the action of the magnetic field, the fixing effect can be produced without physical contact, so it will not cause wear or damage to the storage box 806 or the side plate 805. The base 8 is provided with a side plate 805 and a storage box 806. The side plates 805 are symmetrically distributed on both sides of the storage box 806, and the storage box 806 is installed with a marking module 9. The base 8 is provided with a damping rod 904. The marking module 9 is provided with a rotating seat 903. The rotating seat 903 is rotatably mounted on the damping rod 904. The rotating seat 903 is connected to a plastic curved tube 901. The end of the plastic curved tube 901 away from the rotating seat 903 is installed with a laser indicator 902. The rotating seat 903 is rotatably mounted on the damping rod 904, so that the laser indicator 902 has higher flexibility.The user can adjust the direction and angle of the laser pointer 902 according to the actual detection requirements so as to more accurately mark the defect position in the weld. At the same time, this design also improves the adaptability of the equipment to different working environments and detection requirements. The design of the shapeable elbow 901 allows the user to adjust the position and posture of the laser pointer 902 as needed. The elbow has a certain flexibility and plasticity and can be bent or twisted to adapt to a specific spatial layout or detection requirements. This design not only improves the flexibility of the equipment, but also enables the laser pointer 902 to reach hard-to-reach areas more easily. The laser pointer 902 irradiates and marks the defect position in the weld with a high-precision beam, which has extremely high accuracy. Combined with the design of the shapeable elbow 901 and the rotating seat 903, the user can ensure that the laser beam accurately points to the defect position and improves the detection efficiency and accuracy. By integrating the damping rod 904, the rotating seat 903, the shapeable elbow 901 and the laser pointer 902, the design achieves a compact structure and efficient use of space. This not only reduces the overall volume and weight of the equipment, but also makes the equipment easier to carry and install. At the same time, the compact structure also helps to improve the stability and reliability of the equipment. A power interface is provided on one side end face of the body 7. The body 7 is connected to an external power source through the power interface, and the laser pointer 902 is electrically connected to the terminal block 702 through a power line. The laser pointer 902 is powered by the terminal block 702 of the body 7. This design connects the body 7 to an external power source through the power interface, ensuring that the laser pointer 902 can obtain a stable and reliable power supply. This stable power supply environment helps the laser pointer 902 maintain a normal working state and improves the stability and reliability of the equipment. The external power supply usually has high stability and reliability and can provide a stable voltage and current for the laser pointer 902. This helps to reduce the impact of power fluctuations on the laser pointer 902 and ensure the normal operation of the equipment. The marking modules 9 are evenly distributed in the container box 806, and the marking modules 9 irradiate and mark the detected defect positions.

[0058] Working principle:

[0059] The ultrasonic probe 1 is the core component of the device, which detects the quality of the weld by emitting and receiving ultrasonic waves. When the ultrasonic wave encounters defects in the weld (such as cracks, pores, etc.), reflection, scattering and other phenomena will occur, and the signal received by the probe will change. The signal received by the probe is transmitted to the processing unit in the body 7 through the cable 3 for analysis and processing, so as to determine whether there are defects in the weld and its location, size and other information. The user can set the detection parameters, such as the frequency and gain of the ultrasonic wave, through the control panel 701 on the body 7 to meet different detection requirements. During the detection process, the user can judge the quality of the weld according to the real-time image or data on the display screen 501.

[0060] When the ultrasonic probe 1 is not used for detection, the cable 3 will be automatically reeled under the action of the spring reeling wheel 204 to avoid confusion and loss of the cable 3. The spring reeling wheel 204 provides reeling power through the clockwork spring 202 to ensure that the cable 3 can be reeled smoothly and orderly. When detection is required, the user holds the reel 2 and presses the handle 205. The handle 205 lifts the lower pressure plate 203 through the compression spring 202, thereby releasing the compression and fixation of the cable 3. When stretched to the required length, release the handle 205, and the lower pressure plate 203 will compress and fix the cable 3 again through the compression spring 202. At this time, the user can pull the cable 3 to move the ultrasonic probe 1 to the position to be detected for detection. After the detection is completed, hold the handle 205 again, and the cable 3 will be automatically reeled under the action of the spring reeling wheel 204.

[0061] When the ultrasonic probe 1 detects a defect in the weld, the user takes out the marking module 9 and irradiates and marks the defect position with the laser beam emitted by the marking module 9 .

[0062] The laser pointer 902 is connected to the rotating seat 903 through the plastic curved tube 901, and the rotating seat 903 is rotatably mounted on the damping rod 904. The user can adjust the direction and angle of the laser pointer 902 as needed to ensure the accuracy of the marking. The marking module 9 includes components such as the laser pointer 902, the plastic curved tube 901, the rotating seat 903 and the damping rod 904, which together realize the accurate marking function of the defect position. Multiple marking modules 9 can be installed in the housing box 806 so as to mark multiple defect positions at the same time or replace and adjust according to the detection requirements.
