[0033] The concrete anti-cracking detection device according to the present application will be further described in detail below with reference to specific embodiments and drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms, and is not limited to the embodiments described herein.
[0034] Please refer to Figure 1 In a preferred embodiment, the concrete anti-cracking detection device according to the present application comprises:
[0035] The detection table 1 is provided with a detachable fence 2 on the top, and the area enclosed by the fence 2 forms a detection area 101 for placing a concrete test piece (not shown in the drawings);
[0036] The lifting appliance 3 is erected above the detection area 101, and the lifting appliance 3 comprises a lifting rod 301 and a carrier 302 connected with the lifting rod 301, and a plurality of vibration heads 4 are arranged on the carrier 302;
[0037] A vibration assembly 5 is connected to the boom 301 and used to transmit vibration load to the carrier 302.
[0038] As can be seen from the above technical solution, the lifting device 3 is erected above the detection area 101, and the lifting device 3 includes the boom 301 and the carrier 302, the boom 301 is connected to the carrier 302, and the carrier 302 is provided with a plurality of vibration heads 4. In use, the concrete test piece is first placed in the detection area 101. Then the vibration assembly 5 is started, which transmits vibration load to the carrier 302 through the boom 301, and the vibration load then acts on the concrete test piece through the vibration heads 4, so as to realize the detection of the anti-cracking performance of the concrete by vibration.
[0039] Specifically, the detection table 1 provides a stable support platform for the entire detection device. The design of the detachable fence 2 facilitates the placement and removal of the test piece, while ensuring safety during the detection process. The area enclosed by the fence 2 forms a special detection area 101 for placing the concrete test piece to be detected. The lifting device 3 is composed of the boom 301 and the carrier 302, and is erected above the detection area 101. The boom 301 serves to support and transmit vibration load, while the carrier 302 is used to fix and support the vibration heads 4. The vibration heads 4 are evenly distributed on the carrier 302, ensuring that the vibration load can act uniformly on the concrete test piece. The vibration assembly 5 is the key component for generating and transmitting vibration load. Its output end is connected to the boom 301, and the vibration load is transmitted to the carrier 302 and the vibration heads 4 through the boom 301. The vibration assembly 5 can generate vibrations of different frequencies and amplitudes to simulate the vibration environment of concrete in actual use.
[0040] Further, please refer to Figure 2In some embodiments of the utility model, vibration assembly 5 includes ultrasonic generator 501 and at least one amplitude transformer 502, one end of amplitude transformer 502 is connected with the output end of ultrasonic generator 501, and the other end is connected with boom 301. Ultrasonic generator 501 is the core component of vibration assembly 5, and ultrasonic generator 501 is responsible for generating high-frequency vibration signals. These signals have the characteristics of high energy, good directivity and strong penetration, and are suitable for non-contact vibration detection of concrete test pieces. Amplitude transformer 502 is the key component connecting ultrasonic generator 501 and boom 301. It has the function of amplifying vibration signals, that is, it can amplify the high-frequency vibration signals generated by ultrasonic generator 501 and transmit them to boom 301. At the same time, the design of amplitude transformer 502 can also ensure the stability and consistency of the vibration signals during transmission. When ultrasonic generator 501 starts and generates high-frequency vibration signals, these signals are amplified by amplitude transformer 502 and transmitted to boom 301. Boom 301 transmits the vibration load to carrier 302 and vibration head 4, and finally acts on the concrete test piece. This transmission mode ensures that the vibration load can uniformly and stably act on the surface of the test piece, thereby realizing accurate evaluation of the crack resistance of concrete.
[0041] It should be noted that the amplitude transformer 502 is provided with a mounting hole (not shown in the drawing), and the boom 301 is arranged in the mounting hole. Through the cooperation design of the mounting hole and the boom 301, the stable connection between the two is ensured. This design avoids shaking and displacement during vibration transmission, improves the accuracy and reliability of detection.
[0042] Please refer to Figure 1 In some embodiments of the utility model, the number of amplitude transformers 502 is two, and the two amplitude transformers 302 are oppositely arranged on both sides of the detection table 1, and both of the two amplitude transformers 502 are connected with the output end of the ultrasonic generator 501. Specifically, in use, the high-frequency vibration signals generated by the ultrasonic generator 501 are transmitted to the two amplitude transformers 502 through the output end at the same time. Because the two amplitude transformers 502 are oppositely arranged, they can act on the boom 301 and the carrier 302 in a symmetrical manner, and then transmit to the concrete test piece. This symmetrical vibration loading method helps to improve the accuracy and reliability of detection. The design of double amplitude transformers 502 not only improves the uniformity of vibration loading, but also enhances the stability of the whole vibration assembly 5. In the vibration transmission process, the two amplitude transformers 502 can support and balance each other, avoiding shaking or damage caused by uneven force on a single amplitude transformer 502.
[0043] Further, please refer to Figure 3The carrier 302 is provided with a plurality of groove bodies 3021 extending along the length direction, and the vibration head 4 is installed in the groove body 3021. When the vibration assembly 5 is started, the high-frequency vibration signal generated by the ultrasonic generator 501 is transmitted to the carrier 302 through the amplitude lever 502 and the boom 301. Since the vibration head 4 is directly installed in the groove body 3021, the vibration load can be efficiently transmitted to the vibration head 4 and act on the concrete test piece. This transmission mode reduces energy loss and improves the efficiency of vibration transmission. After receiving the vibration load, the vibration head 4 acts on the concrete test piece to simulate the vibration environment in actual use. By observing and recording the reaction (such as crack generation and expansion) of the test piece during the vibration process, the crack resistance can be evaluated.
[0044] In some embodiments of the present application, the groove bodies 3021 are arranged at intervals on the carrier 302. When the vibration assembly 5 is started, the high-frequency vibration signal generated by the ultrasonic generator 501 is transmitted to the carrier 302 through the amplitude lever 502 and the boom 301. Since the groove bodies 3021 are arranged at intervals, the vibration load can be more evenly distributed and transmitted on the carrier. This helps to reduce energy loss during vibration and improve the efficiency of vibration transmission.
[0045] It should be noted that each groove body 3021 is provided with a plurality of uniformly arranged vibration heads 4. Since a plurality of vibration heads 4 are provided in each groove body 3021, these vibration heads 4 will simultaneously receive the vibration load and act on the concrete test piece. The vibration effect of the plurality of vibration heads 4 can be superimposed on each other, thereby enhancing the vibration effect and improving the accuracy and efficiency of detection. The vibration heads 4 in each groove body 3021 are uniformly distributed according to a predetermined layout, ensuring that each vibration head 4 can apply balanced vibration load to the concrete test piece during vibration. This uniform distribution design helps to reduce energy loss during vibration and improve the efficiency of vibration transmission.
[0046] In particular, in some embodiments of the present application, the end of the vibration head 4 facing the detection area 101 is circular. The circular design reduces energy loss during vibration, improves the efficiency of vibration transmission, and enables the vibration load to be more evenly transmitted to the concrete test piece.
