Description

Technical Field

[0001] This utility model belongs to the technical field of building construction, and in particular relates to a concrete vibration device. Background Technology

[0002] In the field of building construction, concrete vibration is one of the key processes to ensure the quality of concrete structures. Traditional vibration devices are widely used on construction sites to achieve the compaction of concrete. However, with the increasing demands of urban construction on the construction environment, the problems with existing vibration devices are becoming more and more prominent.

[0003] The motors in existing vibratory compaction devices are mostly electromagnetic motors, which generate significant electromagnetic noise during operation. This noise is particularly problematic in densely populated areas or locations with strict noise restrictions. It not only disturbs nearby residents but may also violate local environmental regulations. Furthermore, these devices lack temperature monitoring and protection functions, and the motors may experience performance degradation or even malfunction due to overheating during prolonged continuous operation, thus affecting the construction progress.

[0004] To address these issues, we provide a concrete vibrating device. Utility Model Content

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figures 1-5This utility model is a concrete vibration device, including a handle 1, a flexible hose 2 fixedly connected to one end of the handle 1, and a vibrating rod 3 fixedly connected to the other end of the flexible hose 2; a driving assembly is provided in the inner cavity of the vibrating rod 3, the driving assembly includes an ultrasonic motor 4 fixedly connected to the inner cavity of the vibrating rod 3, a coupling 5 fixedly connected to the output shaft of the ultrasonic motor 4, a spring seat 6 fixedly connected to one end of the coupling 5, a first spring 7 fixedly connected to the other end of the spring seat 6, and an eccentric vibrating hammer 8 fixedly connected to the other end of the first spring 7; a feedback control assembly is provided in the inner cavity of the handle 1, the feedback control assembly includes a control box 9 provided in the inner cavity of the handle 1, a frequency converter 10 provided in the inner cavity of the control box 9, a sound sensor 11 provided in the inner cavity of the vibrating rod 3, an ultrasonic motor drive circuit board 12 provided on one side of the inner cavity of the control box 9, a vibration frequency speed control board 13 provided on the other side of the inner cavity of the control box 9, and a temperature control self-diagnostic adjustment system board 14 provided in the inner cavity of the control box 9.

[0028] Further details: The ultrasonic motor 4, frequency converter 10, sound sensor 11, ultrasonic motor drive circuit board 12, vibration frequency speed control board 13, temperature control self-diagnostic adjustment system board 14, and temperature self-diagnostic sensing device 15 (all existing technologies, their internal structures are not described in detail) replace the traditional electromagnetic motor with the ultrasonic motor 4, using high-frequency vibration to drive the eccentric hammer, avoiding electromagnetic noise. The frequency converter 10 drives the output current of different frequencies according to the received electrical signal. When high noise is detected, the frequency converter 10 outputs a higher frequency current to adjust the working state of the vibrating rod 3, thereby achieving noise reduction. The sound sensor 11 is used to sense... The ambient sound conditions are monitored. When the vibrator 3 emits noise during operation, the sound control sensor 11 converts the received sound signal into an electrical signal. This electrical signal is transmitted to the connected frequency converter 10. The ultrasonic motor drive circuit board 12 provides a suitable drive signal to the ultrasonic motor 4 inside the vibrator 3, enabling it to work normally. The vibration frequency speed control board 13 can adjust the vibration frequency according to different construction requirements (such as different concrete density requirements) and the feedback signal from the sound control sensor 11. The temperature control self-diagnostic adjustment system board 14 is responsible for monitoring the operating temperature of the ultrasonic motor 4 to ensure that it works within a suitable temperature range and avoids performance issues caused by excessively high or low temperatures.

[0029] Example 2

[0030] Please see Figures 1-5Based on Example 1, a temperature self-diagnostic sensor 15 is fixedly connected to the surface of the ultrasonic motor 4. The output terminal of the temperature self-diagnostic sensor 15 is bidirectionally electrically connected to the temperature control self-diagnostic adjustment system board 14. The output terminal of the temperature control self-diagnostic adjustment system board 14 is bidirectionally electrically connected to the input terminal of the ultrasonic motor drive circuit board 12. A self-aligning ball bearing 16 is fixedly connected to the surface of the eccentric vibrating hammer 8. The outer ring of the self-aligning ball bearing 16 is fixedly connected to the inner cavity of the vibrating rod 3. The output terminal of the sound control sensor 11 is bidirectionally electrically connected to the input terminal of the frequency converter 10. The output terminal of the frequency converter 10 is bidirectionally electrically connected to the vibration frequency adjustment system board 12. The input end of the speed plate 13 is bidirectionally electrically connected, the output end of the vibration frequency speed control plate 13 is bidirectionally electrically connected to the input end of the ultrasonic motor drive circuit board 12, the output end of the ultrasonic motor drive circuit board 12 is bidirectionally electrically connected to the input end of the ultrasonic motor 4, a switch button 17 is provided on the surface of the handle 1, a speed control button 18 is provided on one side of the switch button 17, the output end of the speed control button 18 is bidirectionally electrically connected to the input end of the vibration frequency speed control plate 13, a second spring 19 is provided in the inner cavity of the hose 2, one end of the second spring 19 is fixedly connected to one end of the handle 1, and the other end of the second spring 19 is fixedly connected to one end of the vibrating rod 3.

[0031] Further details: The temperature self-diagnostic sensor 15 detects the operating temperature of the ultrasonic motor 4 to prevent overheating damage. Combined with the temperature control self-diagnostic adjustment system board 14, the drive parameters can be dynamically adjusted according to temperature changes. The self-aligning ball bearing 16 is designed to limit the rotation of the eccentric vibrating hammer 8, improving the stability of the rotation of the eccentric vibrating hammer 8. The speed adjustment button 18 is set to facilitate the operator to manually adjust the vibration frequency. The second spring 19 is designed to support the hose 2, ensuring the structural strength of the hose 2.

[0032] The working principle of this utility model is as follows: When the operator presses the switch button 17 on the side of the operating handle 1 to start the device, the control box 9 inside the handle 1 starts to work, providing initial electrical energy to the ultrasonic motor 4 inside the vibrating rod 3. The ultrasonic motor 4 starts to run, and the output shaft of the ultrasonic motor 4 drives the spring to rotate through the coupling and the spring seat 6. The spring drives the eccentric vibrating hammer 8 to vibrate, thus performing the vibration operation on the concrete.

[0033] During the vibration process, the sound control sensor 11 continuously monitors the noise level of the surrounding environment. If the noise exceeds the preset threshold, the frequency converter 10 in the control box 9 will adjust the signal output to the vibration frequency speed control board 13 according to the feedback signal from the sound control sensor 11. The vibration frequency speed control board 13 adjusts the current frequency output to the ultrasonic motor 4 in real time, thereby adjusting the vibration frequency of the vibrating rod 3 to reduce noise. At the same time, the temperature self-diagnostic sensor 15 also continuously monitors the temperature of the ultrasonic motor 4 and feeds the signal back to the temperature control self-diagnostic adjustment system board 14. If the temperature is too high or too low, the control box 9 will also adjust the working state of the ultrasonic motor 4 to ensure its normal operation.

[0034] After the vibration work is completed, the operator removes the vibrator 3. At this time, the sound control sensor 11 detects the change in the surrounding environment (such as the disappearance of the noise source) and feeds the signal back to the frequency converter 10. The frequency converter 10 drives the output of a lower frequency current to the ultrasonic motor 4 through the control system, so that the vibration frequency of the vibrator 3 is reduced, reducing noise generation. Finally, the operator releases the switch button 17, and the vibrator 3 stops working. This avoids noise pollution to nearby residents during the use of traditional vibration devices. It is quieter than traditional vibrators 3, greatly reducing on-site noise pollution, and has high construction efficiency and high turnover rate.
