Technical Field

[0001] This utility model relates to the field of measuring equipment technology, specifically a device for measuring the density of concrete pouring. Background Technology

[0002] With the rapid development of the construction industry, the requirements for controlling the quality of concrete construction are becoming increasingly stringent. The density of poured concrete in walls and bridge piers is a crucial indicator of construction quality, and its accurate measurement is essential for ensuring the stability and durability of buildings. This density can be measured using an ultrasonic concrete density measuring device. However, some existing ultrasonic concrete density measuring devices are cumbersome to operate, requiring multiple people or additional auxiliary tools to complete the measurement. This not only increases labor costs but may also lead to increased measurement errors, and they are inconvenient to use on walls of varying thicknesses. Utility Model Content

[0030] A device for measuring the density of concrete pouring, such as Figures 1-3As shown, the device includes an ultrasonic testing host 50 for measuring the compactness of poured concrete, and a measuring crossbeam 10 for measuring the concrete pouring wall. The measuring crossbeam 10 is equipped with a fixed clamp 20 and an adjustable clamp 30. A motor housing 40 is installed at one end of the measuring crossbeam 10. A movable slide groove 11 is provided on one side of the measuring crossbeam 10. A movable slide 31, which is slidably fitted to the movable slide groove 11, is installed at the end of the adjustable clamp 30. A servo motor 42 is installed inside the motor housing 40. The output shaft of the servo motor 42 is coaxially connected to an adjusting screw 43 inserted into the measuring crossbeam 10. The adjusting screw 43 is threadedly connected to the movable slide 31. The fixed clamp 20... Both the fixed clamp 20 and the adjustable clamp 30 have several evenly spaced insertion slots 21. An ultrasonic generator 22 is mounted on the fixed clamp 20, and an ultrasonic receiver 32 is mounted on the adjustable clamp 30. Through the structure of the measuring frame 10, fixed clamp 20, adjustable clamp 30, motor box 40, moving slide 11, moving slide 31, servo motor 42, and adjusting screw 43, this concrete pouring density measuring device can be operated by a single person. The servo motor 42 drives the adjusting screw 43 to rotate, which in turn drives the moving slide 31 to slide within the moving slide 11, thereby adjusting the position of the adjustable clamp 30 to accommodate concrete pouring walls of different widths. The ultrasonic generator 22 on the fixed clamp 20 and the ultrasonic receiver 32 on the adjustable clamp 30 can work together to calculate the concrete density by measuring the propagation time and speed of ultrasonic waves in the concrete. This device is simple to operate and improves measurement efficiency and accuracy.

[0031] Furthermore, both the ultrasonic generator 22 and the ultrasonic receiver 32 are equipped with connectors 33 that engage with the insertion slots 21, allowing the ultrasonic generator 22 and the ultrasonic receiver 32 to be securely mounted on the fixed clamp 20 and the adjustable clamp 30, which facilitates disassembly and replacement while ensuring the stability and accuracy of the measurement.

[0032] It is worth noting that both the ultrasonic generator 22 and the ultrasonic receiver 32 are embedded in the insertion slot 21, which can protect the ultrasonic generator 22 and the ultrasonic receiver 32.

[0033] Specifically, a handheld lever 41 with an anti-slip sleeve is installed at the end of the motor box 40 away from the measuring crossbar 10. Several sets of control switches 44 are installed on the outer wall of the handheld lever 41 to control the ultrasonic testing host 50 and the servo motor 42 respectively. The handheld lever 41 is convenient for the operator to hold, increasing the operator's comfort. The ultrasonic testing host 50 and the servo motor 42 can be remotely controlled through the control switches 44 on the handheld lever 41, improving the efficiency and convenience of measurement.

[0034] The ultrasonic testing host 50 is equipped with display screens 51 on both sides for synchronously displaying measurement data, enabling operators to view the measurement data in real time and make an intuitive judgment on the compactness of the concrete. The display screens 51 on both sides are convenient for observation.

[0035] In addition, the ultrasonic testing host 50 is equipped with a battery 52, which provides continuous power support for the ultrasonic testing host 50.

[0036] Working principle of this concrete pouring density measuring device:

[0037] First, the operator inserts the connectors 33 of the ultrasonic generator 22 and the ultrasonic receiver 32 into the corresponding connector slots 21 according to the location to be tested, ensuring that they are in close contact with the wall.

[0038] Then, the measuring frame 10 is placed on the concrete wall to be measured, and the servo motor 42 is started by the control switch 44 on the hand lever 41. The servo motor 42 drives the adjusting screw 43 to rotate, which in turn moves the position of the movable slide 31 and the adjustable clamp 30, so that the fixed clamp 20 and the adjustable clamp 30 can firmly clamp the wall.

[0039] Then, the control switch 44 of the ultrasonic testing host 50 is turned on. The ultrasonic generator 22 emits an ultrasonic signal, which passes through the concrete wall and is received by the ultrasonic receiver 32. The ultrasonic testing host 50 calculates the density of the concrete based on the propagation time and speed of the ultrasonic waves and displays the results on the displays 51 on both sides. The operator can evaluate the density of the concrete based on the data on the displays 51.

[0040] Finally, it should be noted that the electronic components in the ultrasonic testing host 50, ultrasonic generator 22, and ultrasonic receiver 32 in this embodiment are all general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components are connected by wires. The specific connection method should refer to the working principle above and complete the electrical connection in the order of operation of each electrical component. All of these are technologies known in the art.
