[0026] Existing large-volume concrete is usually vibrated by an inserted vibrating device. During the vibration process, workers are required to constantly move the vibrating device to different positions, which results in slow construction speed and low efficiency. In addition, the degree of concrete vibration depends solely on the workers' visual observation and judgment, which is greatly affected by the workers' experience. As a result, uneven concrete vibration is prone to occur, and it is difficult to effectively control the density of concrete vibration.
[0027] The present invention provides a large-volume concrete vibrating device, comprising a vibrator 10, a pressure sensor 20 and a controller. The vibrator 10 comprises a vibrating rod 11, a variable frequency motor 12 and a telescopic vibrating block 13. The vibrating rod 11 comprises a hand-held section 111 and a vibrating section 112. The variable frequency motor 12 is installed between the hand-held section 111 and the vibrating section 112. The variable frequency motor 12 is used to drive the vibrating section 112 to vibrate. The telescopic vibrating block 13 is installed on the vibrating section 112. The telescopic vibrating block 13 can be extended in a direction close to or away from the vibrating rod 11. The pressure sensor 20 is installed on the vibrating section 112. The pressure sensor 20 is used to obtain a pressure value in the concrete when the vibrating section 112 is inserted into the concrete. The controller is electrically connected to the pressure sensor 20 and the variable frequency motor 12. The controller is used to control the power of the variable frequency motor 12 according to the pressure value obtained by the pressure sensor 20.
[0028] See also Figure 1 , the vibrating rod 11 extends up and down, the variable frequency motor 12 is installed in the middle of the vibrating rod 11, the part of the vibrating rod 11 located above the variable frequency motor 12 is the hand-held section 111, and the part of the vibrating rod 11 located below the variable frequency motor 12 is the vibrating section 112. When the vibrating section 112 extends into the concrete, the telescopic vibrating block 13 extends in a direction away from the vibrating rod 11, and then the telescopic vibrating block 13 vibrates the concrete driven by the variable frequency motor 12. As the concrete is continuously vibrated, the pressure sensor 20 can obtain the pressure value in the concrete at different vibration degrees in real time, and the controller controls the variable frequency motor 12 to adjust to different powers according to the pressure value obtained by the pressure sensor 20, so that the telescopic vibrating block 13 vibrates the concrete with the corresponding vibration intensity.
[0029] The large-volume concrete vibrating device proposed by the present invention is provided with a telescopic vibrating block 13 installed on the vibrating section 112 of the vibrating rod 11. When the vibrating section 112 is extended into the concrete for vibrating, the telescopic vibrating block 13 can extend in a direction away from the vibrating rod 11 to increase the coverage area of the vibrator 10, thereby increasing the vibration depth and improving the vibration efficiency. The pressure value in the concrete is obtained by installing a pressure sensor 20 on the vibrating section 112 of the vibrating rod 11. The controller controls the power of the variable frequency motor 12 according to the pressure value, so that the vibrator 10 can vibrate the concrete with different vibration intensities according to the concrete under different vibration degrees, and can adjust the vibration intensity in real time to ensure that the bubbles in the concrete are discharged smoothly, so that the stress distribution in the concrete is more uniform, and the density of the concrete after vibration is effectively improved, thereby improving the quality of the concrete.
[0030] In one embodiment, the telescopic vibrating block 13 includes a connecting shaft 131, a scissor rod 132, a driving member 133 and a plurality of vibrating blocks 134. The connecting shaft 131 is passed through the plurality of vibrating blocks 134, and each vibrating block 134 can be slidably matched with the connecting shaft 131. The plurality of vibrating blocks 134 are connected through the scissor rod 132. The driving member 133 is used to drive the scissor rod 132 to telescope in a direction close to or away from the vibrating rod 11 so as to drive each vibrating block 134 to slide along the connecting shaft 131 through the scissor rod 132.
[0031] See also Figure 3 , Figure 3 The schematic diagram of the structure of the telescopic vibrating block 13 of the mass concrete vibrating device provided by the present invention in the extended state. The connecting shaft 131 runs through the middle of each vibrating block 134, and each vibrating block 134 can slide along the connecting shaft 131. The scissor rod 132 is connected to the side of each vibrating block 134, and the telescopic direction of the scissor rod 132 is consistent with the extension direction of the connecting shaft 131. The driving member 133 drives the scissor rod 132 to expand, so as to drive each vibrating block 134 to slide in the direction away from the vibrating rod 11 through the scissor rod 132, so that the distance between any two adjacent vibrating blocks is increased, thereby increasing the vibration range of the vibrator 10 and improving the vibration efficiency.
[0032] In one embodiment, the telescopic vibrating block 13 is installed on the vibrating section 112 through a sliding assembly 14. The sliding assembly 14 includes a slider 141 and a slide rail 142. The slide rail 142 is connected to the vibrating rod 11 and extends in a direction away from the vibrating rod 11. The slider 141 and the slide rail 142 are slidably matched. The connecting shaft 131 is passed through the slider 141. The scissor rod 132 is connected to the slider 141 and multiple vibrating blocks 134. The driving member 133 can drive the slider 141 to slide along the slide rail 142, and can drive the scissor rod 132 to telescope in a direction close to or away from the vibrating rod 11 to drive each vibrating block 134 to slide along the connecting shaft 131 through the scissor rod 132.
[0033] See also Figure 2 , Figure 2 The present invention is a schematic diagram of the structure of the telescopic vibrating block 13 of the large-volume concrete vibrating device in a retracted state. The slide rail 142 is connected to the vibrating rod 11, the connecting shaft 131 is connected to the slider 141 and extends in a direction away from the vibrating rod 11, and the scissor rod 132 is connected to the side of the slider 141 and the multiple vibrating blocks 134. The driving member 133 can drive the slider 141 to slide along the slide rail 142 in a direction away from the vibrating rod 11, so that the slider 141 drives the multiple vibrating blocks 134 away from the vibrating rod 11, and at the same time, the driving member 133 can drive the scissor rod 132 to expand, so as to drive each vibrating block 134 to slide in a direction away from the vibrating rod 11 through the scissor rod 132, so that the slider 141 and the multiple vibrating blocks 134 can provide vibration to the concrete within the range, effectively improving the vibration efficiency. In one embodiment, there are two slide rails 142 , and both sides of the slider 141 can slide with the two slide rails 142 respectively, so that the two slide rails 142 clamp the slider 141 in front of the two slide rails 142 , thereby improving the stability of the slider 141 during the sliding process.
[0034] In one embodiment, the sliding assembly 14 further includes a brush 143 . The brush 143 is installed on a side of the sliding rail 142 facing the sliding block 141 .
[0035] See also Figure 2 The brush 143 is installed on the slide rail 142 and extends to the side of the slider 141. When the telescopic vibrating block 13 completes the vibration, the driving member 133 drives the slider 141 to slide along the slide rail 142 toward the vibrating rod 11. The brush 143 brushes the concrete remaining on the side of the slider 141 to keep the slider 141 clean, thereby extending the service life of the slider 141 and the slide rail 142.
[0036] In one embodiment, the scissor rod 132 is connected to the side of each vibration block 134 through a sleeve 135. It can be understood that during the extension and retraction process of the scissor rod 132, the scissor rod 132 is hinged to the connecting side of each vibration block 134 through the sleeve 135, and the sleeve 135 is provided to enable the scissor rod 132 to rotate relative to the side of each vibration block 134, so as to facilitate the extension and retraction of the scissor rod 132.
[0037] In one embodiment, a shock absorbing block 113 is arranged between the hand-held section 111 and the vibrating section 112, and the shock absorbing block 113 includes a shell 1131 and a shock absorbing pad 1132. The hand-held section 111 and the vibrating section 112 are respectively connected to opposite sides of the shell 1131, and the variable frequency motor 12 and the controller are both installed in the shell 1131, and a shock absorbing pad 1132 is padded between the variable frequency motor 12 and the controller and the inner wall of the shell 1131.
[0038] See also Figure 1The upper and lower sides of the housing 1131 are respectively connected to the hand-held section 111 and the vibrating section 112. The variable frequency motor 12 is installed in the housing 1131. The output shaft of the variable frequency motor 12 extends downward and is connected to the vibrating section 112. When the variable frequency motor 12 drives the vibrating section 112 to vibrate, the shock absorbing block 113 can absorb and isolate the vibration during the vibration process, so that the hand-held section 111 remains as stable as possible. The variable frequency motor 12 and the controller are wrapped in the housing 1131 by the shock absorbing pad 1132 to prevent the variable frequency motor 12 and the controller from colliding with the inner wall of the housing 1131, so that the shock absorbing pad 1132 provides protection for the variable frequency motor 12 and the controller.
[0039] In one embodiment, the handheld section 111 includes a handle 1111 and a shock absorbing plate 1112, and the shock absorbing plate 1112 is disposed between the handle 1111 and the shock absorbing block 113. Furthermore, the shock absorbing plate 1112 separates the handle 1111 from the shock absorbing block 113, and the shock absorbing plate 1112 and the shock absorbing block 113 work together to provide a shock absorbing effect for the handle 1111, further improving the stability and comfort of the operation of the handle 1111.
[0040] In one embodiment, the outer cover of the vibration section 112 is provided with a protective cover 1121 , a pressure probe 1122 is provided on the protective cover 1121 , a pressure sensor 20 is installed in the pressure probe 1122 , and the pressure sensor 20 is connected to the controller via a wire, which is provided in the protective cover 1121 .
[0041] It can be understood that the protective cover 1121 is disposed outside the vibrating rod 11, and the telescopic vibrating block 13 is mounted on the protective cover 1121 and can be telescopic in a direction close to or away from the vibrating rod 11. The protective cover 1121 provides protection for the vibrating section 112, which can reduce the wear of the vibrating section 112 during the vibrating process, thereby extending the service life of the vibrator 10. The pressure probe 1122 extends out of the protective cover 1121 and outward, so as to facilitate the measurement of the pressure value in the concrete.
[0042] In one embodiment, the protective cover 1121 is spaced apart from the vibrating section 112 , and an exhaust passage 1123 is formed between the protective cover 1121 and the vibrating section 112 . Exhaust holes communicating with the exhaust passage 1123 are formed at both ends of the protective cover 1121 .
[0043] Furthermore, when the vibrating section 112 is extended into the concrete for vibration, the gas in the concrete can enter the exhaust channel 1123 from the exhaust hole below the protective cover 1121, and be discharged from the concrete from the exhaust hole above the protective cover 1121. By setting the exhaust channel 1123, the gas in the concrete can be discharged faster, ensuring that the concrete after vibration is more compact.
[0044] The present invention also proposes a mass concrete vibrating method, which uses the mass concrete vibrating device described above. The specific structure of the mass concrete vibrating device refers to the above embodiment. Since the mass concrete vibrating method adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. The mass concrete vibrating method includes the following steps:
[0045] S10: Testing the uniformity of concrete under different pressures and establishing a mapping relationship between pressure value and uniformity;
[0046] S20: Performing a vibration test on concrete with different uniformities, establishing a corresponding relationship between different uniformities and vibration strengths, and inputting the corresponding relationship into a controller;
[0047] S30: inserting the vibrating section into the concrete, and collecting the pressure value of the concrete through the pressure sensor; the processor determines the uniformity of the concrete according to the pressure value, and controls the power of the variable frequency motor according to the uniformity, so that the vibrator reaches the corresponding vibration intensity;
[0048] S40: Expand the telescopic vibrating block and vibrate the concrete by the telescopic vibrating block until the pressure value collected by the pressure sensor reaches a preset value.
[0049] See also Figure 4 , Figure 4 The flow chart of the mass concrete vibrating method provided by the present invention is as follows. Before using the mass concrete vibrating device proposed by the present invention to vibrate concrete, by testing concrete with different uniformities, the corresponding pressure values inside the concrete with different uniformities and the required vibration strengths for the concrete with different uniformities can be obtained. Thus, when the mass concrete vibrating device vibrates the concrete, the pressure sensor 20 can obtain the pressure value inside the concrete, and the controller controls the power of the variable frequency motor 12 according to the pressure value, so that the vibrator 10 can vibrate the concrete with different vibration strengths according to the concrete with different vibration degrees, effectively improving the vibration effect and ensuring that the concrete is vibrated and compacted.
