Description

Technical Field

[0001] This utility model relates to the field of road inspection technology, specifically to an ultrasonic inspection device for municipal roads. Background Technology

[0002] The main road crack detection instruments are ultrasonic crack detectors. Ultrasonic crack detectors can detect whether there are cracks in the road. In the process of using traditional ultrasonic probes, in order to reduce the influence of air on the transmission of ultrasonic waves, it is usually necessary to directly fill the probe and the detection surface with a coupling agent to expel the air. However, filling with coupling agent during road detection will increase the cost of use and make subsequent cleaning difficult.

[0003] A search revealed a Chinese patent for an ultrasonic testing device for municipal roads (publication number: CN222525121U). This patent uses a probe support mechanism to support the probe. When encountering uneven road surfaces, the damper extends and retracts accordingly, ensuring that the caster wheel is in contact with the road surface, thereby maintaining a constant distance between the probe and the road surface.

[0004] While the aforementioned patented method of maintaining a constant distance between the probe and the ground can reduce the impact of distance on detection accuracy, the gap between the probe and the ground will be filled with air, which will affect the transmission of ultrasonic waves and thus affect the detection accuracy. Therefore, those skilled in the art have proposed an ultrasonic testing device for municipal roads. Utility Model Content

[0005] The purpose of this invention is to provide an ultrasonic testing device for municipal roads, which solves the problem in the prior art where air between the probe and the ground affects the transmission of ultrasonic waves.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An ultrasonic testing device for municipal roads, comprising:

[0008] The mounting plate has an ultrasonic testing device on its top and two sets of symmetrically distributed casters on its bottom.

[0009] An auxiliary structure is provided at the bottom of the mounting plate, and the auxiliary structure is used to reduce the impact of gaps on the detection of ultrasonic testing equipment;

[0010] A dust removal structure is disposed on the surface of the mounting plate;

[0011] The auxiliary structure includes a mounting shell disposed at the bottom of the mounting plate, and a connecting cavity is provided inside the mounting shell. The detection probe of the ultrasonic testing equipment passes through the interior of the connecting cavity and is slidably connected to the inner wall of the mounting shell.

[0012] Preferably, the top of the mounting shell is provided with a connecting groove, and a first spring is fixedly connected to the inner wall of the connecting groove. The upper end of the first spring passes through the connecting groove and is fixedly connected to the bottom of the mounting plate.

[0013] Preferably, a storage cylinder is fixedly connected to the top of the mounting plate, a pressing plate is slidably connected inside the storage cylinder, a second spring is fixedly connected between the top of the pressing plate and the inner wall of the storage cylinder, a conduit is connected to the bottom of the storage cylinder, and the other end of the conduit passes through the mounting plate and communicates with the connecting cavity.

[0014] Preferably, both the storage cylinder and the connecting cavity are filled with coupling agent.

[0015] Preferably, the dust removal structure includes a connecting shell fixedly connected to the top of the mounting plate, a filter screen for blocking the opening of the connecting shell is embedded in the top of the connecting shell, a fan is provided inside the connecting shell, and a connecting pipe is connected to the bottom of the connecting shell.

[0016] Preferably, a fixing shell is fixedly connected to the surface of the mounting shell, and the surface of the fixing shell is connected to a uniformly distributed exhaust pipe.

[0017] Preferably, the other end of the connecting pipe extends through the mounting plate and communicates with the interior of the fixed shell.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0019] 1. By setting up an auxiliary structure, the mounting shell can contact the ground to avoid damage caused by collision between the probe and the ground. At the same time, since the probe is located inside the connecting cavity, and the connecting cavity is filled with couplant, together with the storage shell, extrusion plate, conduit and second spring, the connecting cavity is always filled with couplant when the mounting shell contacts the ground under different undulating road conditions. This avoids the situation where gaps exist inside the connecting cavity due to the downward position of the mounting shell, which will affect the transmission of ultrasonic waves. The mounting shell and couplant can reduce the gap between the probe and the ground, which will affect the transmission of ultrasonic waves due to air, and effectively improve the detection accuracy.

[0020] 2. By setting up a dust removal structure, the fan can be actively started during the movement of the device. The fan guides the airflow through the filter screen for filtration, and then the bottom surface of the device in the direction of movement is dusted by the connecting pipe, the fixed shell and the exhaust pipe. This avoids the accumulation of dust from affecting the transmission of ultrasonic waves and further improves the detection accuracy. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 An ultrasonic testing device for municipal roads, comprising:

[0028] Mounting plate 1, with an ultrasonic testing device 2 on the top and two sets of symmetrically distributed casters 101 on the bottom;

[0029] Auxiliary structure 3 is located at the bottom of mounting plate 1. Auxiliary structure 3 is used to reduce the impact of gaps on the detection of ultrasonic testing equipment 2.

[0030] Dust removal structure 4 is disposed on the surface of mounting plate 1;

[0031] The auxiliary structure 3 includes a mounting shell 301 located at the bottom of the mounting plate 1. A connecting cavity 304 is provided inside the mounting shell 301. The detection probe of the ultrasonic testing device 2 passes through the connecting cavity 304 and is slidably connected to the inner wall of the mounting shell 301.

[0032] By installing the mounting shell 301, the detection probe can be protected from direct contact with the ground, which could lead to damage to the detection probe.

[0033] Please see Figure 1-4 The top of the mounting shell 301 is provided with a connecting groove 302. A first spring 303 is fixedly connected to the inner wall of the connecting groove 302. The upper end of the first spring 303 passes through the connecting groove 302 and is fixedly connected to the bottom of the mounting plate 1.

[0034] A storage cylinder 306 is fixedly connected to the top of the mounting plate 1. A compression plate 307 is slidably connected inside the storage cylinder 306. A second spring 308 is fixedly connected between the top of the compression plate 307 and the inner wall of the storage cylinder 306. A conduit 305 is connected to the bottom of the storage cylinder 306. The other end of the conduit 305 passes through the mounting plate 1 and is connected to the connecting cavity 304.

[0035] Both the storage cylinder 306 and the connecting cavity 304 are filled with coupling agent.

[0036] By setting the first spring 303, the mounting shell 301 can always be in contact with the ground. The position of the mounting shell 301 can be changed by squeezing the first spring 303 according to the undulation of the road, which can adapt to different road conditions. At the same time, the coupling agent filled inside the connecting cavity 304 can ensure that the ultrasonic waves generated by the ultrasonic testing equipment 2 can be transmitted well, avoiding the situation where there are gaps between the detection probe and the road surface or air affecting the ultrasonic detection. Furthermore, as the mounting shell 301 changes position with the undulation of the road, it can work with the squeezing plate 307, the second spring 308 and the conduit 305 to adjust the coupling agent inside the connecting cavity 304, ensuring that the coupling agent inside the connecting cavity 304 is always full, and avoiding the situation where gaps caused by the downward movement of the mounting shell 301 affect the transmission of ultrasonic waves.

[0037] Please see Figure 1-4 The dust removal structure 4 includes a connecting shell 401 fixedly connected to the top of the mounting plate 1. A filter screen 402 for blocking the opening of the connecting shell 401 is embedded in the top of the connecting shell 401. A fan 403 is provided inside the connecting shell 401. A connecting pipe 404 is connected to the bottom of the connecting shell 401.

[0038] A fixed housing 405 is fixedly connected to the surface of the mounting housing 301, and a uniformly distributed exhaust pipe 406 is connected to the surface of the fixed housing 405.

[0039] The other end of the connecting pipe 404 passes through the mounting plate 1 and is connected to the interior of the fixed shell 405.

[0040] By starting the fan 403, outside air can be guided through the filter screen 402 for filtration. The filtered air is then introduced into the fixed housing 405 through the connecting pipe 404 and finally discharged through the exhaust pipe 406. During this process, the exhaust pipe 406 can remove dust from the ground in the direction of the device's movement, reducing the impact of dust accumulation on the ultrasonic wave transmission and effectively improving the detection accuracy.

[0041] Working principle: By setting the auxiliary structure 3, it can be ensured that the bottom surface of the mounting shell 301 is always in contact with the ground during the movement of the device, and that the coupling agent inside the connecting cavity 304 is always filled to avoid the situation where gaps are caused by the downward movement of the mounting shell 301, which affects the ultrasonic transmission. At the same time, it can work with the dust removal structure 4 to remove dust from the ground in the direction of the device's movement during the movement, reducing the impact of dust accumulation on the ground and affecting the ultrasonic transmission, thus effectively improving the detection accuracy.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
