Description

An ultrasonic detector for detecting surface fissures Technical Field

[0001] This utility model relates to the field of ultrasonic testing instruments, specifically an ultrasonic testing instrument for detecting surface fissures. Background Technology

[0002] Surface fissure detection is of great significance in fields such as geological exploration, construction quality inspection, and road and bridge maintenance. Traditionally, this type of detection work often relies on manual operation using handheld ultrasonic testing instruments. However, in practical applications, this method has revealed several problems and inconveniences.

[0003] First, when using traditional handheld ultrasonic detectors, operators need to frequently bend over or squat to ensure the probe is in close contact with the ground for detection. This method is not only inefficient but also places a significant strain on the operator's body, potentially leading to occupational health problems with prolonged use. Second, because one hand needs to hold the probe while the other operates the main unit for data reading and analysis, this operation limits flexibility and convenience. Especially in complex terrain conditions, this single operating method can severely restrict work efficiency. Therefore, a new ultrasonic detector for surface crack detection is needed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide an ultrasonic detector for detecting surface fissures, which has the advantages of convenient operation, high efficiency and stability, and portability, and solves the problems of inconvenient operation, low efficiency and physical burden on operators of traditional handheld ultrasonic detectors.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic detector for detecting surface fissures, comprising a main unit and a detection probe, wherein the detection probe is provided with a stepping mechanism;

[0006] The detection probe includes a transducer and a data cable. The transducer transmits data to the host via the data cable. The pedaling mechanism includes a sliding sleeve, a pedal clamp, and an elastic band. The sliding sleeve is fitted onto the outer end of the transducer and slidably connected to it. A first rotating shaft is provided at the bottom of the side end face of the pedal, and the pedal is rotatably connected to the sliding sleeve via the first rotating shaft. A second rotating shaft is provided on the side end face of the clamp and rotatably connected to the pedal. The upper end of the elastic band is fixed to the end of the clamp away from the second rotating shaft, and the lower end of the elastic band is fixed to the end of the pedal away from the first rotating shaft.

[0007] In a preferred embodiment of the ultrasonic detector for detecting surface fissures according to this utility model, the outer end face of the sliding sleeve is provided with a first storage groove corresponding to the shape of the pedal, the pedal is installed at the bottom of the first storage groove, the inner end face of the first storage groove is provided with a slot, and the side end face of the pedal is provided with a locking strip that cooperates with the slot.

[0008] In a preferred embodiment of the ultrasonic detector for detecting surface fissures according to this utility model, the upper end surface of the pedal is provided with a second storage groove corresponding to the shape of the clamp, and the clamp is installed in the second storage groove.

[0009] In a preferred embodiment of the ultrasonic detector for detecting surface fissures according to this utility model, the lower end face of the clamp is provided with a magnet that engages with the foot pedal.

[0010] As a preferred embodiment of the ultrasonic detector for detecting surface fissures according to this utility model, the bottom of the first receiving groove is provided with a limiting plate to restrict the rotation angle of the pedal.

[0011] In a preferred embodiment of the ultrasonic detector for detecting surface fissures according to this utility model, the upper end face of the transducer is provided with a guide groove, a spring is provided in the guide groove, and the lower end face of the sliding sleeve is provided with a guide rod that slides in cooperation with the guide groove. The sliding sleeve and the transducer are elastically slidably connected through the guide groove, the guide rod and the spring.

[0012] As a preferred embodiment of the ultrasonic detector for detecting surface fissures according to this utility model, the bottom of the guide rod is provided with a limiting slip head to prevent the slip sleeve from falling off.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model utilizes a combination structure of a flip-up pedal, clamp, and elastic band in its foot pedal mechanism. The operator can use their foot to step on the pedal to drive the sliding sleeve to press down on the transducer, making it fit tightly against the ground. This allows for stable detection of the probe without the need for handheld operation, freeing up both hands to operate the main unit. The ring formed by the clamp and elastic band can fix the device to the shoe upper, and the probe position can be adjusted by moving the foot. This solves the pain point of traditional detection requiring frequent bending over or hand operation, significantly improving detection efficiency and reducing labor intensity.

[0015] 2. The sliding sleeve and pedal of this utility model are respectively provided with a first storage groove and a second storage groove. With the help of magnetic adsorption and slot locking structure, the pedal and clamp can be folded and stored in the groove, which prevents the parts from shaking or accidentally unfolding when carrying. At the same time, it reduces the size of the equipment. The design of the limiting plate precisely controls the unfolding angle of the pedal, ensuring that the direction of the stepping force is vertically downward, which prevents slippage and avoids the probe tilting. These structures work together to solve the problem of the large size and inconvenience of traditional equipment, while ensuring the stability during operation.

[0016] 3. The transducer and the sliding sleeve of this utility model are elastically connected through a guide rod, a spring and a limiting slider. When stepped on, the spring provides controllable downward pressure, which not only ensures that the transducer is fully in contact with the ground, but also avoids excessive pressure that could damage the probe. The limiting slider further restricts the movement range of the sliding sleeve, preventing the sliding sleeve from falling off or the transducer from accidentally detaching when the foot is lifted. This solves the problem of easy damage to equipment caused by traditional rigid pressure structures and improves the safety and reliability of long-term use. Attached Figure Description

[0023] Please refer to Figures 1-5. An ultrasonic detector for detecting surface fissures includes a main unit 1 and a detection probe 2. The detection probe 2 is equipped with a stepping mechanism 3.

[0024] The detection probe 2 includes a transducer 201 and a data cable 202. The transducer 201 transmits data to the host 1 via the data cable 202. The pedal mechanism 3 includes a sliding sleeve 301, a pedal 302, a clamping plate 303, and an elastic band 304. The sliding sleeve 301 is fitted onto the outer end of the transducer 201 and slidably connected to it. A first rotating shaft 3023 is provided at the bottom of the side end face of the pedal 302. The pedal 302 is rotatably connected to the sliding sleeve 301 via the first rotating shaft 3023. A second rotating shaft 3031 is provided on the side end face of the clamping plate 303 and rotatably connected to the pedal 302. The upper end of the elastic band 304 is fixed to the end of the clamping plate 303 away from the second rotating shaft 3031, and the lower end of the elastic band 304 is fixed to the end of the pedal 302 away from the first rotating shaft 3023.

[0025] The pedal 302 can be flipped outward along the first pivot 3023. The user can press down the transducer 201 by stepping on the pedal 302, so that the transducer 201 is in contact with the ground and remains stable, thus freeing up both hands to operate the main unit 1. After the user is proficient in stepping on the pedal 302, the clamp 303 can be flipped outward along the second pivot 3031. At this time, the clamp 303, the elastic band 304 and the inside of the pedal 302 form a ring, which can be fitted onto the shoe. Thus, the foot drives the detection probe 2 to move and detect different areas of the ground. The elastic band 304 protrudes upward to form a pull ring shape, which makes it easy to pull and quickly unfold the pedal 302.

[0026] Furthermore, the outer end face of the sliding sleeve 301 is provided with a first storage groove 3011 corresponding to the shape of the pedal 302. The pedal 302 is installed at the bottom of the first storage groove 3011. The inner end face of the first storage groove 3011 is provided with a slot 3012. The side end face of the pedal 302 is provided with a retaining strip 3021 that cooperates with the slot 3012.

[0027] By providing a first storage groove 3011 on the side end face of the sliding sleeve 301, the pedal 302 can be flipped upward along the first rotating shaft 3023 and stored in the first storage groove 3011. The cooperation of the locking strip 3021 and the locking groove 3012 improves the stability of the pedal 302 and prevents the pedal 302 from unfolding on its own during carrying.

[0028] Furthermore, the upper end surface of the pedal 302 is provided with a second storage groove 3022 corresponding to the shape of the clamp 303, and the clamp 303 is installed in the second storage groove 3022.

[0029] When not in use, the clamp 303 can be stored in the second storage slot 3022 without affecting the use of the pedal 302. When the pedal 302 is flipped upward and stored in the first storage slot 3011, the clamp 303 can also be stored in the first storage slot 3011 together, reducing the space occupied and improving the portability of the device.

[0030] Furthermore, the lower end face of the clamping plate 303 is provided with a magnet 3032 that is attracted and engaged with the pedal 302.

[0031] The magnetic 3032 is used to attract the clamp 303, which improves the stability of the clamp 303 and the pedal 302, and prevents the clamp 303 from popping open on its own when not in use, thus affecting operation. It also prevents shaking and abnormal noise during carrying.

[0032] Furthermore, a limiting plate 3014 is provided at the bottom of the first storage slot 3011 to limit the rotation angle of the pedal 302.

[0033] The limit plate 3014 restricts the rotation angle of the pedal 302, which facilitates the application of force when stepping on it, and at the same time controls the direction of the force to be vertically downward. This prevents slippage when stepping on it and also prevents the detection probe 2 from tilting.

[0034] Furthermore, the upper end face of the transducer 201 is provided with a guide groove 2011, and a spring 2012 is provided in the guide groove 2011. The lower end face of the sliding sleeve 301 is provided with a guide rod 3013 that slides in cooperation with the guide groove 2011. The sliding sleeve 301 and the transducer 201 are elastically slidably connected through the cooperation of the guide groove 2011, the guide rod 3013 and the spring 2012.

[0035] When the user steps on the pedal 302, the pedal 302 drives the sliding sleeve 301 to slide downwards. Then, the spring 2012 generates downward pressure on the transducer 201, which improves the contact between the transducer 201 and the ground. On the other hand, the sliding stroke of the sliding sleeve 301 is greater than the height of the pedal 302 off the ground. The elastic connection structure avoids excessive downward pressure that could damage the transducer 201, thus improving the stability of the equipment.

[0036] Furthermore, the bottom of the guide rod 3013 is provided with a limiting slide head 3015 to prevent the slide sleeve 301 from falling off.

[0037] By limiting the upward sliding stroke of the guide rod 3013 through the limiting slider 3015, the sliding sleeve 301 is prevented from falling off when the user lifts their foot, thus preventing the transducer 201 from being pulled out and causing wear on the transducer 201 during movement, thereby improving the stability of the equipment.

[0038] When using this testing instrument, firstly, if it is necessary to bring the transducer 201 into contact with the ground for testing, the testing probe 2 can be moved to the testing area. Since the pedal 302 can be flipped outward along the first rotating shaft 3023, the pedal 302 can be flipped until it is parallel to the ground. The user can then step on the pedal 302. At this time, the pedal 302 drives the sliding sleeve 301 to press down on the transducer 201, making the transducer 201 stably in contact with the ground. This frees up both hands to operate the main unit 1. After the user is familiar with operating the pedal 302, if different areas of the ground need to be tested, the clamp 303 can be moved along the second rotating shaft 3031. When the foot is flipped outwards, a ring is formed inside the clamping plate 303, elastic band 304, and pedal 302. This ring allows the foot-operated mechanism 3 to be fitted onto the shoe. The foot moves the detection probe 2 within a small range. When the desired location is reached, the pedal 302 is pressed down for detection. During the carrying process, because the outer end face of the sliding sleeve 301 is provided with a first storage groove 3011 corresponding to the shape of the pedal 302, the pedal 302 can be flipped upwards along the first rotating shaft 3023 and stored in the storage groove. Furthermore, the retaining strip 3021 on the side end face of the pedal 302 cooperates with the retaining groove 3012 on the inner end face of the storage groove, preventing the pedal 302 from being flipped outwards. 2. Self-unfolding: The upper surface of the pedal 302 is provided with a second storage groove 3022 corresponding to the shape of the clamp 303. When the clamp 303 is not in use, it can be hidden in the groove. When the pedal 302 is flipped upward and retracted into the first storage groove 3011, the clamp 303 can also be retracted, reducing space occupation. In addition, the magnet 3032 on the lower surface of the clamp 303 can be attracted and engaged with the pedal 302, improving the stability of the engagement and preventing the clamp 303 from popping open on its own. When in use, the limiting plate 3014 at the bottom of the first storage groove 3011 restricts the rotation angle of the pedal 302, making it easier for the user to step and exert force. The direction of force is controlled by a spring 2012 installed in the guide groove 2011 on the upper end face of the transducer 201. The guide rod 3013 on the lower end face of the sliding sleeve 301 slides in cooperation with the guide groove 2011. The sliding sleeve 301 and the transducer 201 are elastically slidably connected through this structure. When the user steps on the pedal 302, the pedal 302 drives the sliding sleeve 301 to slide downward. The spring 2012 generates downward pressure on the transducer 201, which improves the fit and avoids damage to the transducer 201 due to excessive pressure. At the same time, the limiting slide head 3015 at the bottom of the guide rod 3013 can prevent the sliding sleeve 301 from falling off, thus improving the stability of the equipment.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
