Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of weld detection, in particular to a bridge steel structure cross-shaped weld detection device. BACKGROUND

[0002] Highway lines pass through rivers, harbors, lakes, reservoirs, irrigation canals and other water areas, or cross deep valley areas with large height differences, or cross other traffic lines. In order to maintain smooth traffic, bridges need to be erected. In the production of welded structures, the quality of the welds obtained by the welding technology currently used has not yet reached sufficient stability. In order to ensure the quality of the welded components, the welds must be inspected to ensure that the welds meet the specified technical requirements and the safety of the structure for use. Non-destructive testing of welds refers to the use of ultrasonic testing, magnetic particle testing or penetrant testing to inspect whether the weld quality meets the specified requirements and design intent without damaging the performance and integrity of the inspected weld.

[0003] After searching, patent No. CN202021151057.9 discloses a highway bridge bridge steel structure cross-shaped weld detection device. Although the device can be used by winding the wire 5 on the winding wheel 41 for one turn, holding the handle 43, driving the winding wheel 41 to rotate forward, winding the remaining wire 5 on the winding wheel 41, then hanging the L-shaped rod 45 on one side of the detection probe 3 in the through hole 46 on the fixed plate 44, thereby fixing the detection probe 3 on the weld detection body 1, taking the L-shaped rod 45 on the detection probe 3 out of the through hole 46 of the fixed plate 44 during detection, holding the handle 43, reversing the winding wheel 41, and stretching 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, it is cooled through the heat dissipation holes 7, the dust screen 9 prevents dust from entering the weld detection body 1 through the heat dissipation holes 7, the bolt 8 beside the dust screen 9 is unscrewed, and the dust screen 9 can be disassembled and cleaned. However, when a defect is detected, other equipment or devices are needed to mark the defect position, which not only increases the complexity of the operation, but also may reduce the detection efficiency, because additional marking tools need to be frequently switched or carried during the detection process. Moreover, the display screen and the control interface are directly exposed to the outside, lacking necessary protection. During transportation or carrying, these vulnerable components are easily impacted, scratched or contaminated, resulting in equipment damage or function failure. This not only increases maintenance costs, but also may affect the accuracy and reliability of detection. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a bridge steel structure cross-shaped weld detection device, which solves the problems raised in the background art.

[0005] The technical problems solved by the present application are as follows:

[0006] A bridge steel structure cross-over weld detection device, comprising a machine body, an upper cover is rotatably installed on the machine body through a damping hinge, an ultrasonic probe is connected to the machine body through a cable, and a base is installed at the bottom end of the machine body.

[0007] A control panel is arranged on the machine body, a wiring board is arranged on the back of the machine body, the cable is connected to the machine body through the wiring board, a winding device is installed at the end of the cable away from the machine body, the ultrasonic probe is located on the winding device, and the cable is connected to the ultrasonic probe through the winding device.

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

[0009] On the basis of the above technical solution, the present application can also be improved as follows.

[0010] Further, a handle is installed at the end of the machine body away from the wiring board, and the machine body is carried through the handle.

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

[0012] The design of the handle 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 in cases where on-site detection is required or multiple detections are performed at different locations. Direct lifting or carrying the machine body may increase the risk of impact or damage. The design of the handle provides a dedicated and more stable gripping point, which helps to reduce damage caused by accidental falling or collision during carrying or moving.

[0013] Further, the base is connected and fixed to the machine body through bolts, sliding blocks are arranged on both sides of the containing box, sliding grooves are formed in the side plates, and the containing box is limitingly and slidably installed between the side plates through the sliding blocks and the sliding grooves.

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

[0015] The base is connected and fixed with the machine body by bolts. This connection mode is relatively tight, which can effectively ensure the stability and firmness between the machine body and the base. The bolt connection not only has high strength, but also has certain anti-seismic and anti-impact ability, which can adapt to complex working environment. Compared with welding and other fixing methods, the bolt connection can be conveniently installed and disassembled. This makes it possible to complete the related operation more quickly and efficiently when maintenance, replacement of parts or adjustment of equipment layout is needed, thereby reducing the maintenance cost and time cost. The containing box is installed between the side plates by sliding through the sliding block and the sliding groove. This design allows the position of the containing box to be adjusted within a certain range. This provides greater flexibility for users, who can adjust the position of the containing box according to actual work needs, so as to better place or take out the articles (such as marking modules) therein.

[0016] Further, the containing box is inlaid with a second magnet, and the side plate is inlaid with a first magnet. After the containing box is slid into position, the second magnet and the first magnet are fixed between the two side plates by mutual attraction.

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

[0018] The attraction force between the magnets can provide strong fixing effect, ensuring that the containing box can be tightly fixed between the two side plates after being slid into position, and is not easy to shake or displace. This fixing method is more stable and reliable than traditional mechanical locking or buckle fixing. The magnet attraction fixing method allows users to fix and release the containing box without using additional tools or operations. Users only need to slide the containing box to the specified position, and the magnets will automatically attract and fix the containing box. When the containing box needs to be released, only a certain external force is needed to overcome the attraction force of the magnets, and the operation is very convenient. Compared with traditional mechanical locking or buckle fixing method, the magnet attraction fixing method will not cause wear or damage. Because the attraction force between the magnets is realized by magnetic field action, no physical contact is needed to produce the fixing effect, so there is no wear or damage to the containing box or the side plate.

[0019] Further, the base is provided with a damping rod, the marking module is provided with a rotating seat, the rotating seat is rotatably installed on the damping rod, the rotating seat is connected with a shapeable elbow pipe, and the shapeable elbow pipe is provided with a laser indicator at one end away from the rotating seat.

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

[0021] The rotating seat is rotatably installed on the damping rod, so that the laser pointer has higher flexibility. Users can adjust the direction and angle of the laser pointer according to actual detection needs, 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 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 layout or detection requirements. 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 irradiates and marks the defect position in the weld through a high-precision light beam, 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 position, improving detection efficiency and accuracy. By integrating the damping rod, rotating seat, shapeable elbow, and laser pointer, the design achieves compact structure and efficient use of space. This not only reduces the overall volume and weight of the equipment, but also makes it easier to carry and install. At the same time, the compact structure also helps to improve the stability and reliability of the equipment.

[0022] Further, a spring winding wheel is rotatably installed in the winding device by a clockwork spring, and the cable is uniformly wound on the spring winding wheel in the winding device.

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

[0024] The clockwork spring provides power for the automatic winding of the spring winding wheel. After the cable is released for detection or other purposes, the clockwork spring automatically drives the spring winding wheel to rotate, uniformly winding the cable back, without the need for manual operation. This automatic function greatly improves work efficiency and reduces the tediousness of manual operation. Since the cable is uniformly wound on the spring winding wheel in the winding device, there is no problem of cable knotting or winding disorder. This not only makes the cable more smooth during release and winding, but also facilitates the user's taking and arranging during use. Through automatic winding and uniform winding, the cable is orderly stored and managed in the winding device. This avoids problems such as wear and tear and aging of the cable due to long-term disordered storage, thereby prolonging the service life of the cable.

[0025] Further, a handle is installed in the winding device, the handle is provided with a lower pressing plate in the winding device, an upper pressing plate is provided above the lower pressing plate in the winding device, a spring is provided between the upper pressing plate and the lower pressing plate, and the handle is elastically supported by the spring.

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

[0027] The design of the handle makes it more convenient for users to operate the winder. Through the handle, users can easily control the winding and releasing actions of the winder without directly touching or operating other components inside the winder. This design improves the convenience of operation, allowing users to quickly complete the winding and releasing work of the cable. Integrating components such as the handle, lower pressing plate, upper pressing plate, and spring inside the winder achieves compact structure and efficient use of space. This design not only reduces the overall volume and weight of the winder, but also makes it easier to carry and install. At the same time, the compact structure also helps to improve the stability and reliability of the winder.

[0028] Further, a through hole is formed through the lower pressing plate, the cable passes through the through hole of the lower pressing plate, and the lower pressing plate is pressed down by the spring to press and fix the cable.

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

[0030] The lower pressing plate presses and fixes the cable through the spring, which can ensure that the cable remains stable in the winder and is not easily loose or detached. The spring force provides continuous pressing force, so that the cable can maintain a stable position during winding and releasing. Since the spring pressing and fixing method is used, the user can quickly fix the cable in the winder without using additional tools or performing complex operations. Similarly, when releasing the cable, it is only necessary to simply release the pressing state of the lower pressing plate, which is very convenient to operate.

[0031] Further, a power interface is formed on one side end surface of the machine body, the machine body is in communication with an external power source through the power interface, and the laser indicator is electrically connected to the wiring board through a power line, and the laser indicator is powered through the wiring board of the machine body.

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

[0033] The design connects the machine body with the external power source through the power interface, ensuring that the laser indicator can obtain stable and reliable power supply. This stable power supply environment helps the laser indicator to maintain normal working state, improving the stability and reliability of the equipment. The external power source usually has high stability and reliability, which can provide stable voltage and current for the laser indicator. This helps to reduce the influence of power fluctuation on the laser indicator and ensures the normal operation of the equipment.

[0034] The present application provides a bridge steel structure cross intersection weld detection device.

[0035] Advantages:

[0036] The device is designed with a handle for easy carrying and moving, making the detection work more flexible and convenient. The upper cover is rotatably connected to the machine 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 for accurate detection of weld quality, improving the accuracy and efficiency of detection. The spring winding wheel is arranged in the winder, which can automatically wind the cable, avoiding the confusion and loss of the cable, and also facilitating the pulling and winding of the cable. The design of the handle makes the user can easily control the winding and unwinding of the cable, further improving the convenience of operation.

[0038] The base is fixedly connected to the machine body by bolts, providing a stable support platform to ensure the stability of the detection process. The containing box is limited to slide between the side plates through the sliding block and the sliding groove, and is fixed by the mutual attraction of the second magnet and the first magnet. This design not only ensures the stability of the containing box, but also facilitates the adjustment of its position. The setting of the marking module makes the detected defect position can be accurately marked, improving the intuitiveness and traceability of the detection result. BRIEF DESCRIPTION OF DRAWINGS

[0055] In order to facilitate the stretching or winding of the cable 3, for example, Figures 1 to 5As shown, the application also includes: the body 7 is provided with a control panel 701, the back of the body 7 is provided with a wiring board 702, the cable 3 is connected with the body 7 through the wiring board 702, the end of the cable 3 away from the body 7 is provided with a winding device 2, the ultrasonic probe 1 is located on the winding device 2, the cable 3 is connected with the ultrasonic probe 1 through the winding device 2, the spring winding wheel 204 is rotatably installed in the winding device 2 through the clockwork spring, the cable 3 is uniformly wound on the spring winding wheel 204 in the winding device 2, the clockwork spring 202 provides power for the automatic winding of the spring winding wheel 204. When the cable 3 is released for detection or other purposes, the clockwork spring 202 will automatically drive the spring winding wheel 204 to rotate, and the cable 3 will be uniformly wound back, without manual operation. This automatic function greatly improves the work efficiency and reduces the tediousness of manual operation. Since the cable 3 is uniformly wound on the spring winding wheel 204 in the winding device 2, there will be no problems such as knotting and winding disorder. This not only makes the cable 3 more smooth during release and winding, but also facilitates the user to take, place and arrange during use. Through the automatic winding and uniform winding mode, the cable 3 is orderly stored and managed in the winding device 2. This avoids the problems such as wear and tear and aging caused by long-term disordered storage of the cable 3, thereby prolonging the service life of the cable 3. The winding device 2 is provided with a handle 205, the handle 205 is located in the winding device 2 and provided with a lower pressing plate 203, an upper pressing plate 201 is provided above the lower pressing plate 203 in the winding device 2, a spring 202 is provided between the upper pressing plate 201 and the lower pressing plate 203, and the handle 205 is elastically supported by the spring 202.

Through the handle 205, the user can easily control the winding and release actions of the winding device 2 without directly touching or operating other components in the winding device 2. This design improves the convenience of operation, so that the user can complete the winding and release work of the cable 3 more quickly. Integrating the handle 205, the lower pressing plate 203, the upper pressing plate 201 and the spring 202 and other components inside the winding device 2 realizes compact structure and efficient use of space. This design not only reduces the overall volume and weight of the winding device 2, but also makes the winding device 2 easier to carry and install. At the same time, the compact structure also helps to improve the stability and reliability of the winding device 2. The lower pressing plate 203 is provided with a through hole, the cable 3 penetrates through the through hole of the lower pressing plate 203, and the lower pressing plate 203 is pressed and fixed to the cable 3 through the spring. When the cable 3 needs to be wound, the user holds the winding device 2 and presses the handle 205, the handle 205 compresses the spring 202 and then releases the cable 3, so as to facilitate the cable 3 to be pulled or wound. The lower pressing plate 203 is pressed and fixed to the cable 3 through the spring 202, this fixing mode can ensure that the cable 3 remains stable in the winding device 2 and is not easy to loosen or fall off. The elastic force of the spring 202 provides continuous pressing force, so that the cable 3 can maintain a stable position during winding and release.Due to the adoption of the spring 202 downward pressing and compacting fixing mode, the user can quickly fix the cable 3 in the winder 2 without using additional tools or performing complex operations. Similarly, when it is necessary to release the cable 3, it is only necessary to simply release the compacting state of the downward pressing plate 203, and the operation is very convenient.

[0056] Example Three

[0057] In order to facilitate the irradiation marking of the detected defect position, for example, as shown in the figure, Figures 1 to 7As shown, the application also includes: the base 8 is connected and fixed with the body 7 by bolts, both sides of the containing box 806 are provided with sliding blocks 803, the side plates 805 are provided with sliding grooves 801, the containing box 806 is limitingly and slidingly installed between the side plates 805 through the sliding blocks 803 and the sliding grooves 801, the base 8 is connected and fixed with the body 7 by bolts, this connection mode is relatively close, which can effectively ensure the stability and firmness and reliability between the body 7 and the base 8. The bolt connection not only has high strength, but also has certain anti-seismic and anti-impact capacity, which can adapt to complex and changeable working environment. Compared with other fixing modes such as welding, the bolt connection can be conveniently installed and disassembled. This makes it possible to complete the related operation more quickly and efficiently when maintenance, component replacement or equipment layout adjustment is needed, thereby reducing the maintenance cost and time cost. The containing box 806 is limitingly and slidingly installed between the side plates 805 through the sliding blocks 803 and the sliding grooves 801, this design makes the position of the containing box 806 adjustable within a certain range. This provides greater flexibility for users, which can adjust the position of the containing box 806 according to actual work needs, so as to better place or take out the articles (such as the marking module 9) therein. The containing box 806 is inlaid with second magnets 804, the side plates 805 are inlaid with first magnets 802, the containing box 806 is fixed between the two side plates 805 by mutual adsorption of the second magnets 804 and the first magnets 802 after sliding into position, the adsorption force between the magnets can provide strong fixing effect, which ensures that the containing box 806 can be tightly fixed between the two side plates 805 after sliding into position and is not prone to shaking or displacement. This fixing mode is more stable and reliable than the traditional mechanical locking or buckle fixing. The magnet adsorption fixing mode makes it possible for users to complete the fixing and release of the containing box 806 without using additional tools or operations. Users only need to slide the containing box 806 to the specified position, and the magnets will automatically adsorb and fix the containing box 806; when the containing box 806 needs to be released, only a certain external force needs to be applied to overcome the adsorption force of the magnets, which is very convenient. Compared with the traditional mechanical locking or buckle fixing mode, the magnet adsorption fixing mode will not cause wear or damage. Because the adsorption force between the magnets is realized through magnetic field action, physical contact is not needed to produce the fixing effect, so the containing box 806 or the side plate 805 will not be worn or damaged, the base 8 is provided with the side plates 805 and the containing box 806, the side plates 805 are symmetrically distributed on both sides of the containing box 806, and the marking module 9 is installed in the containing box 806, 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 installed on the damping rod 904, the rotating seat 903 is connected with a plastic bend pipe 901, one end of the plastic bend pipe 901 away from the rotating seat 903 is provided with a laser indicator 902, and the rotating seat 903 is rotatably installed 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 needs, in order to more accurately mark the defect position in the weld. At the same time, this design also improves the adaptability of the device 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 requirement. This design not only improves the flexibility of the device, but also makes it easier for the laser pointer 902 to reach difficult-to-reach areas. The laser pointer 902 marks the defect position in the weld by irradiating it with a high-precision light beam, with 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, improving detection efficiency and accuracy. By integrating the damping rod 904, the rotating seat 903, the shapeable elbow 901, and the laser pointer 902 together, this design achieves a compact structure and efficient use of space. This not only reduces the overall volume and weight of the device, but also makes it easier to carry and install. At the same time, the compact structure also helps to improve the stability and reliability of the device. The side end face of the machine body 7 is provided with a power interface, the machine body 7 is in communication with the external power supply through the power interface, and the laser pointer 902 is electrically connected with the wiring board 702 through the power line. The laser pointer 902 is powered through the wiring board 702 of the machine body 7. This design connects the machine body 7 with the external power supply through the power interface, ensuring that the laser pointer 902 can obtain stable and reliable power supply. This stable power supply environment helps the laser pointer 902 to maintain normal working state, improving the stability and reliability of the device. The external power supply usually has high stability and reliability, which can provide stable voltage and current for the laser pointer 902. This helps to reduce the influence of power fluctuations on the laser pointer 902, ensuring the normal work of the device. The marking modules 9 are evenly distributed in the containing box 806, and the marking modules 9 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 waves encounter defects in the weld, such as cracks, pores, etc., reflection, scattering, and other phenomena occur, and the signals received by the probe change. The signals received by the probe are transmitted to the processing unit in the machine body 7 through the cable 3 for analysis and processing, so as to judge whether the weld has defects and the position, size, etc. of the defects. The user can set detection parameters such as the frequency and gain of the ultrasonic waves through the control panel 701 on the machine body 7 to adapt to different detection needs. During the detection process, the user can judge the quality of the weld according to the real-time images or data on the display screen 501.

[0060] When the ultrasonic probe 1 is not being used for testing, the cable 3 will automatically wind up under the action of the spring winding wheel 204, preventing the cable 3 from becoming tangled or lost. The spring winding wheel 204 provides winding power through the spring spring 202, ensuring that the cable 3 can be wound up smoothly and orderly. When testing is required, the user holds the winder 2 and presses the handle 205. The handle 205 lifts the lower pressure plate 203 through the compression spring 202, thereby releasing the clamping and fixing of the cable 3. When stretched to the required length, the user releases the handle 205, and the lower pressure plate 203 clamps and fixes 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 testing position for testing. After the test is completed, the user holds the handle 205 again, and the cable 3 will automatically wind up under the action of the spring winding wheel 204.

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

[0062] The laser pointer 902 is connected to the rotating base 903 via a malleable bend 901, and the rotating base 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 marking accuracy. The marking module 9 includes components such as the laser pointer 902, the malleable bend 901, the rotating base 903, and the damping rod 904, which together achieve the accurate marking function of defect locations. Multiple marking modules 9 can be installed in the housing 806 to mark multiple defect locations simultaneously or to be replaced and adjusted according to inspection needs.
