Description

Technical Field

[0001] The invention belongs to the technical field of construction equipment, and in particular relates to a vibration mixing device and method for high-speed construction. Background Art

[0002] As a new concrete mixing technology, vibration mixing technology has unique advantages over ordinary mixing. It combines the forced mixing of blades with the vibration of the mixing shaft to achieve uniformity of the mixture in a short time. Secondly, in the face of the inherent low-efficiency areas of mixing machinery, vibration mixing technology has achieved improvements and enhancements, thereby improving the quality of the mixture and greatly enhancing efficiency.

[0003] General concrete vibrating and stirring is only provided with a vibration motor and a mixing drum. When the distribution of concrete in the mixing drum, viscosity and other parameters change, it is impossible to automatically adjust the intensity of vibration or stirring according to the parameters. For this reason, Chinese patent CN216707897U discloses an intelligent vibration stirring device, which includes a mixing box, and the intelligent vibration stirring device also includes a stirring shaft, which is arranged in the mixing box and can rotate relative to the mixing box, and the stirring shaft is provided with a stirring arm, and a mounting cavity is provided on the stirring arm; a vibrator, which is arranged in the mounting cavity and fixedly connected to the stirring arm, and the vibrator has an output end; a vibration member, which is installed at the output end of the vibrator, and the vibration member covers the mounting cavity; an elastic sealing gasket, which is arranged in the Between the vibrating member and the stirring arm; a pressure sensor, which is installed on the stirring arm, and the vibrating member abuts against the pressure sensor; it can detect the state of concrete in the mixing box in real time, and control the vibrator in time to achieve a better vibration stirring effect; however, in the above structure, although a pressure sensor is provided to detect the pressure in the entire mixing drum and then adjust the vibration, the concrete being mixed exhibits certain fluid properties and is unevenly distributed in the mixing drum. Simple pressure detection cannot detect the unevenly distributed cement in the mixing drum in steps, and the detection result is not accurate enough. Therefore, the adjustment based on the detection result is not accurate enough, and the vibration stirring effect is not good. Therefore, a vibration stirring device and method for high-speed construction with high detection accuracy and good vibration stirring effect is needed. Summary of the Invention

[0004] In order to solve the above problems existing in the prior art, the present invention provides a vibration mixing device and method for high-speed construction, which has the characteristics of high detection accuracy and good vibration mixing effect.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A vibrating mixing device for high-speed construction, comprising a mixing drum, a vibration platform, and a control module. The mixing drum is disposed on the vibration platform. A stirring shaft is disposed in the mixing drum. One end of the stirring shaft passes through the bottom of the mixing drum and is connected to a rotating motor.

A plurality of stirring rods are disposed on the surface of the stirring shaft.

[0007] The mixing drum is slidably connected to the mixing shaft, and the mixing drum is connected to a rotator, which is used to drive the mixing drum to rotate in the opposite direction of the rotation direction of the rotation shaft.

[0008] A weight distribution sensor is provided on the surface of the vibration table, and the weight distribution sensor is used to detect the center of gravity distribution on the vibration table and upload it to the control module. The control module increases the vibration power of the mixing drum when the center of gravity distribution is far away from the stirring shaft, and increases the vibration power of the stirring shaft when the center of gravity distribution is close to the stirring shaft.

[0009] As a preferred technical solution of the present invention, several first pressure sensors are provided on several stirring rods, and several second pressure sensors are provided on several stirring blades. Several of the first pressure sensors and the second pressure sensors are electrically connected to the control module respectively. Several of the first pressure sensors are used to detect the pressure around the stirring rods and upload it to the control module. Several of the second pressure sensors are used to detect the pressure around the stirring blades and upload it to the control module. The control module adjusts the rotation speed of the stirring shaft and the stirring drum according to the stirring rod pressure and the stirring blade pressure respectively.

[0010] As a preferred technical solution of the present invention, the control module increases the vibration power of the stirring rod and reduces the vibration power of the stirring drum when the stirring rod pressure is greater than the stirring blade pressure. The control module reduces the vibration power of the stirring rod and increases the vibration power of the stirring drum when the stirring rod pressure is less than the stirring blade pressure.

[0011] As a preferred technical solution of the present invention, several of the first pressure sensors are used to detect the pressure P1 around the stirring rod and upload it to the control module, and several of the second pressure sensors are used to detect the pressure P2 around the stirring blade and upload it to the control module. The control module calculates the values ​​of A1 and A2 respectively, and instructs the vibration power of the mixing drum to be adjusted to A1 times, and the vibration power of the stirring shaft to be adjusted to A2 times;

[0013] As a preferred technical solution of the present invention, the control module is electrically connected to two vibration frequency analyzers, which are used to measure the vibration frequencies of the stirring rod and the stirring drum respectively. The control module determines whether the phase difference between the vibration of the stirring rod and the vibration of the stirring drum is less than a threshold value. When the judgment result is yes, the control module instructs the vibration table to delay the vibrator of the stirring rod.

[0020] (3) By staggering the control module to adjust the power of the mixing drum and the mixing shaft, the simultaneous increase of the power of the mixing shaft and the mixing drum is avoided, which reduces the probability of concrete being compacted in the mixing drum, thereby reducing the probability of a decrease in the mixing effect;

[0021] (4) By making the control module analyze the vibration frequency of the stirring rod and the stirring drum, and when the vibration frequency phases of the stirring rod and the stirring drum are close and less than the threshold, the vibration table is instructed to delay the vibration phase of the vibrator of the stirring rod, thereby reducing the probability of the vibration phases of the stirring rod and the stirring drum overlapping, thereby reducing the probability of vibration affecting the structural life of the stirring drum and the stirring shaft, and improving the durability of the equipment.

[0028] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0029] See also Figure 1-3 A high-speed construction vibration mixing equipment includes a mixing drum 1, a vibration platform 3 and a control module 4. The mixing drum 1 is set on the vibration platform 3. A mixing shaft 2 is set in the mixing drum 1. One end of the mixing shaft 2 passes through the bottom of the mixing drum 1 and is connected to a rotating motor. The rotating motor is used to drive the mixing shaft 2 to rotate. The axis of the mixing shaft 2 coincides with the axis of the mixing drum 1. A plurality of stirring rods 21 are set on the surface of the mixing shaft 2.

[0030] Specifically, the mixing drum 1 is cylindrical, and an opening with an area consistent with the cross-section of the mixing shaft 2 is opened at the center of the bottom surface of the mixing drum 1. One end of the mixing shaft 2 extends out of the mixing drum 1 through the opening. At this time, one end of the mixing shaft 2 passes through the bottom of the mixing drum 1, and the mixing drum 1 and the mixing shaft 2 are slidably connected;

[0031] At the same time, the mixing drum 1 is connected to a rotator 11, which is used to drive the mixing drum 1 to rotate in the opposite direction of the rotation direction of the rotation axis. The inner wall of the mixing drum 1 is provided with a plurality of mixing blades 12, and the plurality of mixing blades 12 are staggered with a plurality of stirring rods 21. The mixing shaft 2 and the mixing drum 1 are respectively connected to a vibrator 22, which is used to vibrate the mixing shaft 2 and the mixing drum 1;

[0032] As for the structure of the vibration table 3, specifically, the stirring rod 21 is additionally connected to a vibrator 22, and a bearing platform 13 is provided on the vibration table 3. The bearing platform 13 includes two inclined surfaces facing the mixing drum 1, and a roller 14 is provided on each inclined surface. The roller 14 is cylindrical, and the axis of the roller 14 is parallel to the axis of the mixing drum 1, and the side of the roller 14 is tangent to the side of the mixing drum 1. At this time, the roller 14 provides support for the mixing drum 1 below the mixing drum 1 and fixes the mixing drum 1 on the vibration table 3. When the mixing drum 1 rotates, the mixing drum 1 drives the roller 14 to rotate, and the roller 14 provides the mixing drum 1 with a degree of freedom of rotation. At the same time, when the vibration table 3 vibrates, the vibration mechanical wave is transmitted to the mixing drum 1 along the vibration table 3, the bearing platform 13 and the roller 14, completing the vibration of the mixing drum 1 while realizing the rotation of the mixing drum 1 itself;

[0033] During use, the operator adds the concrete to be mixed into the mixing drum 1, rotates the motor to drive the mixing shaft 2 to rotate, and the mixing drum 1 rotates in the reverse direction. The supporting platform 13 and the roller 14 maintain the mixing drum 1 in place, realizing the relative rotation of the mixing drum 1 and the mixing shaft 2. At the same time, the mixing blades 12 and the stirring rods 21 arranged in the space inside the mixing drum 1 and staggered with each other stir the concrete therein to complete the mixing of the concrete. The shock waves of the vibrating table 3 and the vibrator 22 are transmitted to the mixing blades 12 and the stirring rods 21 to complete the vibration mixing of the concrete.

[0034] During the above process, the concrete being mixed exhibits certain fluid properties, and there is a probability that the concrete will be unevenly distributed in the mixing drum 1. When the concrete is more distributed on the inner wall of the mixing drum 1, it has less contact with the mixing shaft 2 and the mixing rod 21. At this time, increasing the vibration intensity of the mixing shaft 2 has limited effect on improving the vibration mixing effect. Similarly, when the concrete is more distributed around the mixing shaft 2, increasing the vibration intensity of the mixing drum 1 has limited effect on improving the mixing effect. In order to accurately adjust the vibration intensity according to the distribution of concrete, a weight distribution sensor is provided on the surface of the vibration table 3. The weight distribution sensor is used to detect the center of gravity distribution on the vibration table 3 and upload it to the control module 4. The control module 4 increases the vibration power of the mixing drum 1 when the center of gravity distribution is far away from the mixing shaft 2, and increases the vibration power of the mixing shaft 2 when the center of gravity distribution is close to the mixing shaft 2.

[0035] Specifically, the weight distribution sensor is an array composed of several weight sensors, and several weight sensors are arranged on the surface of the vibration table 3 supporting the mixing drum 1. Several weight sensors are electrically connected to the control module 4 and upload the pressure they are subjected to. When concrete is distributed around the mixing drum 1, the weight sensors located at the vibration table 3 away from the center are subjected to more pressure. At this time, the control module 4 judges that the concrete is distributed on the inner wall of the mixing drum 1 through the changes in data uploaded by the weight sensors arranged in the array. At this time, the control module 4 increases the vibration power of the mixing drum 1; when concrete is concentrated on the surface of the mixing shaft 2, the weight sensors located near the center of the vibration table 3 are subjected to more pressure. At this time, the control module 4 judges that the concrete is distributed on the surface of the mixing shaft 2 through the changes in data uploaded by the weight sensors arranged in the array. At this time, the control module 4 increases the vibration power of the mixing shaft 2;

[0036] By providing a weight distribution sensor and enabling the control module 4 to adjust the vibration intensity in a targeted manner according to the weight distribution, the detection accuracy is improved, thereby improving the accuracy of the adjustment based on the detection results and improving the vibration stirring effect.

[0037] In the above process, although the vibration intensity is adjusted according to the distribution of concrete, in addition to the vibration intensity, the rotation speed of the mixing drum 1 will also affect the effect of vibration mixing. For this reason, a number of first pressure sensors are provided on the stirring rods 21, and a number of second pressure sensors are provided on the stirring blades 12. The first pressure sensors and the second pressure sensors are electrically connected to the control module 4 respectively. The first pressure sensors are used to detect the pressure around the stirring rods 21 and upload it to the control module 4. The second pressure sensors are used to detect the pressure around the stirring blades 12 and upload it to the control module 4. The control module 4 adjusts the rotation speed of the stirring shaft 2 and the mixing drum 1 according to the pressure of the stirring rods 21 and the pressure of the stirring blades 12 respectively.

[0038] Specifically, when the pressure around the stirring rod 21 detected by the first pressure sensor is relatively high, it means that more cement has accumulated on the stirring rod 21. It is necessary to further increase the rotation speed of the stirring rod 21 to shake off some of the concrete while enhancing the mixing effect on the surrounding concrete. At this time, the control module 4 increases the rotation speed of the stirring shaft 2. Similarly, when the pressure of the stirring blade 12 detected by the second pressure sensor is relatively high, it means that more cement has accumulated on the surface of the stirring blade 12. It is necessary to further increase the rotation speed of the mixing drum 1 to shake off some of the concrete and enhance the mixing effect on the surrounding concrete. At this time, the control module 4 increases the rotation speed of the mixing drum 1.

[0039] By setting a first pressure sensor and a second pressure sensor to detect the pressure of the stirring rod 21 and the pressure of the stirring blade 12, and enabling the control module 4 to increase the speed of the stirring shaft 2 when the pressure of the stirring rod 21 increases, and to increase the speed of the mixing drum 1 when the pressure of the stirring blade 12 increases, the speed is adjusted according to the distribution of concrete, further improving the adjustment accuracy while improving the vibration stirring effect.

[0040] In the above process, there is a probability that the vibration intensity of the mixing drum 1 and the vibration intensity of the mixing shaft 2 will be increased at the same time. At this time, the concrete therein is likely to be compacted by the staggered mixing blades 12 and the mixing shaft 2 under the action of high-power vibration, resulting in partial compaction and solidification of the concrete in the mixing drum 1, which reduces the mixing effect. To avoid such a situation, the control module 4 increases the vibration power of the stirring rod 21 and reduces the vibration power of the mixing drum 1 when the pressure of the stirring rod 21 is greater than the pressure of the stirring blade 12. The control module 4 reduces the vibration power of the stirring rod 21 and increases the vibration power of the mixing drum 1 when the pressure of the stirring rod 21 is less than the pressure of the stirring blade 12.

[0041] Specifically, the vibrator 22 that applies vibration to the stirring rod 21 and the mixing drum 1 is two stepper motors. The two stepper motors apply vibration to the stirring rod 21 and the mixing drum 1 respectively. The control module 4 outputs electrical signals of the same frequency to the two stepper motors, so that the vibrator 22 applies vibrations of the same frequency to the mixing drum 1 and the stirring rod 21. The control module 4 controls the output torque of the two stepper motors respectively, thereby adjusting the vibration power of the mixing drum 1 and the stirring rod 21 respectively.

[0042] When the control module 4 increases the vibration power of one of the mixing drum 1 or the mixing shaft 2, it reduces the vibration power of the other component, thereby achieving staggered adjustment of the vibration power of the mixing drum 1 and the mixing shaft 2;

[0043] In the above adjustment process, specifically, the control module 4 is pre-input with a standard pressure value P0, a plurality of first pressure sensors are used to detect the pressure P1 around the stirring rod 21 and upload it to the control module 4, and a plurality of second pressure sensors are used to detect the pressure P2 around the stirring blade 12 and upload it to the control module 4. The control module 4 calculates the values ​​of A1 and A2 respectively, and instructs the vibration power of the mixing drum 1 to be adjusted to A1 times, and the vibration power of the stirring shaft 2 to be adjusted to A2 times, wherein A1=P1 / P0×c; A2=P2 / P0×c, and c is a pre-calculated constant;

[0044] When P1 > P2, A1 > A2. When the control module 4 instructs the vibration power of the mixing drum 1 to be adjusted to A1 times and the vibration power of the mixing shaft 2 to be adjusted to A2 times, it is completed to increase the vibration power of the mixing shaft 2 and decrease the vibration power of the mixing drum 1 when the pressure of the stirring rod 21 is greater than the pressure of the stirring blade 12; similarly, when P2 < P1, A1 < A2. When the control module 4 instructs the vibration power of the mixing drum 1 to be adjusted to A1 times and the vibration power of the mixing shaft 2 to be adjusted to A2 times, it is completed to increase the vibration power of the mixing drum 1 and decrease the vibration power of the mixing shaft 2 when the pressure of the stirring blade 12 is greater than the pressure of the stirring rod 21;

[0045] By making the control module 4 stagger the adjustment of the power of the mixing drum 1 and the mixing shaft 2, the simultaneous increase in the power of the mixing shaft 2 and the mixing drum 1 is avoided, the probability of the concrete being compacted in the mixing drum 1 is reduced, and further the probability of the mixing effect decreasing is reduced.

[0046] In the above process, when the mixing drum 1 and the mixing shaft 2 vibrate at the same frequency, there is a probability that the vibration waves of the contact part between the two will be superimposed, resulting in a resonance phenomenon. Furthermore, the structure of the contact part between the two is more affected by the vibration, accelerating the consumption of the structural life of the mixing drum 1 and the mixing shaft 2. To avoid such a situation, the control module 4 is electrically connected to two vibration frequency analyzers. The two vibration frequency analyzers are respectively used to measure the vibration frequencies of the stirring rod 21 and the mixing drum 1. The control module 4 judges whether the phase difference between the vibration of the stirring rod 21 and the vibration of the mixing drum 1 is less than the threshold value. When the judgment result is yes, the control module 4 instructs the vibrator 22 to delay the vibration phase of the stirring rod 21;

[0047] Specifically, when the control module 4 judges that the phase difference between the vibration of the stirring rod 21 and the vibration of the mixing drum 1 is less than the threshold value, the control module 4 counts the complete phase of half of the vibration wave of the mixing shaft 2, denoted as the reference phase. Subsequently, the control module 4 counts the time corresponding to the reference phase, denoted as the delay time, and stops sending the electrical signal to the stepping motor until the electrical signal is resent after a delay time. The phase difference threshold value can be manually input in advance by the operator or automatically calculated by the control module 4;

[0048] By making the control module 4 analyze the vibration frequencies of the stirring rod 21 and the mixing drum 1, and when the vibration frequency phases of the stirring rod 21 and the mixing drum 1 are relatively close and less than the threshold value, instructing the vibration table 3 to delay the vibration phase of the vibrator 22 of the stirring rod 21, the probability of the vibration phases of the stirring rod 21 and the mixing drum 1 overlapping is reduced, and further the probability of the vibration affecting the structural life of the mixing drum 1 and the mixing shaft 2 is reduced, improving the durability of the equipment.

[0049] During the adjustment process, when the vibration power of the stirring rod 21 and the stirring drum 1 is large and resonance occurs, the impact on the life of the equipment structure is greater. At this time, it is necessary to stagger the vibration phases of the stirring drum 1 and the stirring rod 21 as much as possible, and improve the judgment standard for whether the vibration phases of the stirring rod 21 and the stirring drum 1 are too close. When the vibration power of the stirring rod 21 and the stirring drum 1 is small, resonance occurs, and the impact on the life of the equipment structure is smaller. At this time, too frequently detecting whether the vibration phases of the stirring rod 21 and the stirring drum 1 are too close, and stopping the electrical signal sent to the stepper motor when the detection result is yes, until the electrical signal is sent again after a delay time, will cause the vibration stirring equipment to frequently Stopping the machine when it is not necessary will affect the construction efficiency. At this time, there is no need to stagger the vibration phases of the mixing drum 1 and the stirring rod 21 to a large extent. For this purpose, the control module 4 is pre-input with a phase difference reference value ω0. The control module 4 calculates the phase difference threshold value ω according to the power P1 of the mixing drum 1, the vibration power P2 of the stirring rod 21 and the phase difference reference value ω0; wherein, the phase difference threshold value ω=[-1 / (x+2)+0.5]×ω0, x=(P1+P2) / 2, c is a pre-input constant, x≥0.1, and the phase difference reference value ω0 is obtained by calculating the 360° corresponding phase after counting the vibration wave phase of the mixing drum 1 by the control module 4. When the calculation result shows that x<0.1, the control module 4 takes x=0.1;

[0050] When the vibration frequency analyzer is used to measure the vibration wave phase of the stirring rod 21 and the stirring drum 1 respectively and uploads it to the control module 4, the control module 4 obtains the function of the vibration frequency over time and obtains the phase of the vibration wave accordingly. A complete cycle of the vibration wave, that is, the phase of the vibration wave corresponding to 360° is the phase difference reference value ω0. At this time, since the vibration frequencies of the stirring drum 1 and the stirring rod 21 are the same, when the vibration phases of the stirring drum 1 and the stirring rod 21 differ by ω0 / 2, the phase difference between the two is 180°, and the phase difference reaches the maximum value.

[0051] When the power of the mixing drum 1 and the stirring rod 21 is large, it means that resonance occurs, which has a greater impact on the life of the equipment structure. At this time, it is necessary to stagger the vibration phases of the mixing drum 1 and the stirring rod 21 as much as possible, and it is necessary to improve the judgment standard for whether the vibration phases of the stirring rod 21 and the mixing drum 1 are too close. At this time, the value of (P1+P2) / 2 is large, and the value of the phase difference threshold ω=(P1+P2) / 2×c×ω0 is large, approaching ω0 / 2, completing the process of adjusting the power of the mixing drum 1 and the stirring rod 21. When the vibration phases of the mixing drum 1 and the stirring rod 21 are large, it is necessary to stagger the vibration phases of the mixing drum 1 and the stirring rod 21 as much as possible, and improve the phase difference threshold. The value of the value ensures that when the vibration wave phases of the mixing drum 1 and the stirring rod 21 are close to each other to a smaller extent, the control module 4 will instruct the vibrator 22 to delay the vibration phase of the stirring rod 21, thereby ensuring the phase difference between the mixing drum 1 and the stirring rod 21. When the value of (P1+P2) / 2 is further increased, ω=[-1 / (x+2)+0.5]×ω0 approaches ω0 / 2. At this time, the control module 4 ensures that when the vibration phases of the mixing drum 1 and the stirring rod 21 slightly deviate from the maximum value ω0 / 2, an instruction is issued, thereby ensuring that the vibration phases of the mixing drum 1 and the stirring rod 21 are staggered as much as possible.

[0052] Similarly, when the power of the mixing drum 1 and the stirring rod 21 is large, the impact on the life of the equipment structure is smaller. At this time, there is no need to stagger the vibration phases of the mixing drum 1 and the stirring rod 21 as much as possible. At this time, the value of (P1+P2) / 2 is small, and the value of the phase difference threshold ω=(P1+P2) / 2×c×ω0 is small. When the power of the mixing drum 1 and the stirring rod 21 is small and there is no need to stagger the vibration phases of the mixing drum 1 and the stirring rod 21 as much as possible, the value of the phase difference threshold is reduced to ensure construction efficiency.

[0053] In order to facilitate the input of constants such as c, ω0 and P0, a control panel is also included. The control panel is electrically connected to the control module 4 and is used to input the values ​​of c, ω0 and P0.
