Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an intelligent vibrator for precision construction. Background Technology

[0002] The quality of concrete vibration construction directly affects the overall strength, durability, and safety of the structure. Traditional vibration operations have long relied on manual experience, which has problems such as the inability to quantify and record key process parameters such as vibration time and insertion depth, and difficulty in ensuring operational accuracy. This can easily lead to over-vibration or under-vibration, resulting in a decrease in the homogeneity of the concrete and thus creating potential quality hazards for the structure.

[0003] Especially in municipal engineering projects, such as vacuum flushing wells and tunnel segments, the subsequent repairs caused by insufficient compaction often consume a lot of manpower and time. Therefore, it is necessary to effectively control the key technical points during concrete vibration construction to ensure that the vibration operation meets the specifications and guarantees that the concrete has the required strength and good appearance quality after molding.

Detailed Implementation

[0020] Example 1 like Figure 1 , 2 In section 5, an intelligent vibrator for precision construction includes a vibrating head 1, a power pipe 2, and a handheld box 3. The vibrating head 1 is connected to the handheld box 3 via the power pipe 2. A pressure sensor 5 is installed at the bottom of the vibrating head 1, and an infrared rangefinder 15 is installed on one side of the handheld box 3. The pressure sensor 5 is used to time the vibration by detecting the contact pressure between the vibrating head 1 and the concrete. The handheld box 3 is used to detect the insertion depth of the vibrating head 1 and to process and calculate the data from the pressure sensor 5 and the infrared rangefinder 15.

[0021] In the construction of cast-in-place concrete structures, especially complex structures such as vacuum flushing wells, traditional concrete vibration operations rely heavily on the experience and responsibility of workers. This results in uncontrollable and unmeasurable key parameters such as vibration time, insertion depth, and effective range. This can easily lead to quality defects such as honeycombing, pitting, and lack of compaction due to inadequate vibration (under-vibration or over-vibration), causing large-scale rework, project delays, and increased construction costs. This invention aims to overcome these shortcomings by providing an integrated intelligent vibrator that enables real-time monitoring, intelligent judgment, and feedback of key parameters throughout the vibration process, fundamentally improving the standardization and quality control of vibration operations.

[0022] Especially when conducting vibration tests on concrete, it is necessary to accurately record vibration parameters, insertion angle, insertion depth, and insertion point location to analyze the differences in appearance and internal details of the solidified concrete block and summarize the most suitable parameter range. Therefore, accurately recording the vibration process is the core and most basic step for obtaining accurate data. However, current vibration operations lack the steps and processes for accurately obtaining the above data, leading to non-standard construction practices.

[0023] The pressure sensor installed on the vibrating head 1 in this application can detect the contact pressure with the concrete in real time. The pressure sensor is integrated into the tip of the vibrating head and has a range of 0.5–2.0 MPa. It is used to detect the contact pressure between the vibrating head and the concrete and uses the pressure signal as the start and end signals of single-point vibration timing. The infrared rangefinder can acquire and record the insertion depth of the vibratory head 1, thereby achieving accurate data acquisition. Through the cooperation of the above components, the accuracy of the data during vibration is guaranteed.

[0024] like Figure 3-6 In the preferred embodiment, the top of the handheld box 3 is provided with an indicator light 301, a buzzer 302 and a handle 303. The two sides of the handheld box 3 are respectively provided with a protective cover 304 and a power supply module 305. The power pipe 2 passes through the protective cover 304. The other side of the handheld box 3 is also detachably provided with an electronic level 7.

[0025] By holding the handle 303 and combining the parameters on the electronic level 7, the operator can accurately obtain the current tilt angle of the handheld box 3, which facilitates the subsequent acquisition of the insertion angle of the vibrator head 1. In traditional construction processes, the insertion angle is mainly controlled by the experience of the workers, which results in inconsistent benchmarks.

[0026] The power pipe 2 passes through the protective sleeve 304, preventing breakage and damage at the end connecting the power pipe 2 to the handheld box 3 due to repeated bending. Indicator light 301 provides guidance on vibration specifications; when the vibration angle and depth are within the allowable range, indicator light 301 turns green; when exceeding the allowable range, indicator light 301 turns red, and buzzer 302 sounds an alarm. Power supply module 305 provides the power base for all components. Furthermore, power supply module 305 uses a removable battery, facilitating easy installation, removal, and battery replacement, thereby improving operational efficiency.

[0027] like Figure 7-9 In the preferred embodiment, a fixing frame 8 is detachably provided on the lower side of the protective sleeve 304. The fixing frame 8 includes a first bracket 801 and a second bracket 802. The first bracket 801 is connected to the handheld box 3 by screws 14. The first bracket 801 and the second bracket 802 are hinged together. Multiple reversing units 9 are respectively provided on the first bracket 801 and the second bracket 802. The power tube 2 is wound around the reversing unit 9. A triaxial acceleration sensor 4 is provided on the top of the vibrating head 1. A straight tube 13 is detachably provided on the upper side of the vibrating head 1. The power tube 2 passes through the straight tube 13. The straight tube 13 is connected by a U-shaped clip 813 and a second bracket 802. A controller 6 is provided between the buzzer 302 and the handle 303. The controller 6 includes a display screen 601 and buttons 602.

[0028] The fixing frame 8 is made of lightweight materials, such as carbon fiber, ensuring strength while maintaining a light overall weight for easy handling and operation. The fixing frame 8 can constrain the power pipe 2 and control the angle of the vibrating head 1. Because the first support 801 and the second support 802 can change their bending angle as needed, such as... Figure 3 In most cases, it is necessary to ensure that the vibrator head 1 is vertically aligned and inserted into the concrete for vibration. At the same time, for ease of use, when the construction worker holds the handle 303, the handheld box 3 may have an initial tilt angle. At this time, the electronic level 7 obtains the angle of the handheld box 3 that the construction worker is accustomed to, and adjusts the angle between the first support 801 and the second support 802 to ensure that the second support 802 is perpendicular to the concrete. At the same time, since the power pipe 2 bends during the adjustment of the angle of the first support 801 and the second support 802, the reversing unit 9 ensures the safety and efficiency of the adjustment, avoids the problem of the power pipe 2 bending and being damaged, and at the same time, the power pipe 2 is constrained as a whole, making the power transmission more direct and efficient. When tilting vibration is required, after obtaining the initial tilt angle of the handheld box 3 under the operating habits of the construction personnel, the angles of the first support 801 and the second support 802 are adjusted accordingly to achieve convenient control of the above process. By setting the straight pipe 13, the interval of the vibrating head 1 is realized, and the angle constraint of the vibrating head 1 can be relatively stably realized. The controller 6 is equipped with a display screen 601, which displays various parameters. The tolerance alarm prompt range can also be adjusted by the button 602.

[0029] Since there are still scenarios where inclined vibration is used, the straight pipe 13 is used for transition and connection constraint, thereby ensuring the accurate insertion angle of the vibration head 1. This avoids the process of manually holding the upper end of the vibration head 1 for insertion and vibration under normal operation, and avoids contact impact or injury to personnel.

[0030] In the preferred embodiment, the first bracket 801 is hinged to the second bracket 802 via the second shaft 808. The second shaft 808 is also provided with a transfer wheel 10. The transfer wheel 10 is sleeved on the second shaft 808 via a fixed cylinder 1001. An angle adjustment unit 11 is also provided on both sides of the second shaft 808. The infrared rangefinder 15 is set at the lower part of the second bracket 802 via a ranging unit 12. The lower part of the second bracket 802 is provided with a sealing plate 807. The sealing plate 807 is symmetrically provided with square holes 811. The square holes 811 are provided with second threaded holes 812 through both sides. The U-shaped clip 813 is provided with countersunk holes 814 on both sides. The U-shaped clip 813 and the square holes 811 are inserted into each other. The screw 14 passes through the second threaded holes 812 and the countersunk holes 814.

[0031] The adapter wheel 10 enables angle changes for the power pipe 2 and also constrains it, ensuring smooth bending movements. The U-shaped clip facilitates easy installation and removal, allowing for angle control of the straight pipe 13 while providing some room for movement. The angle adjustment unit 11 assists construction personnel in precisely adjusting and locking the angle between the first support 801 and the second support 802. Simultaneously, the ranging unit 12 adaptively adjusts its position based on the angle between the second support 802 and the horizontal plane, ensuring that the infrared rangefinder 15's working direction is directly facing the concrete surface, resulting in more accurate data. This allows for accurate determination of the insertion depth of the vibrator head 1 based on the angle between the second support 802 and the horizontal plane. All of these processes ensure precise and efficient vibration compaction.

[0032] like Figure 11-16 In the preferred embodiment, the first support 801 includes a first support plate 803, and the second support 802 includes a second support plate 805. The first support plate 803 and the second support plate 805 are respectively provided with a first clamping plate 804 and a second clamping plate 806 on their sides. The tops of the two first clamping plates 804 are connected by a reversing unit 9, and the bottoms of the two second clamping plates 806 are connected by a reversing unit 9. The reversing unit 9 includes a base plate 901, and side plates 902 are respectively provided on both sides of the base plate 901. The two side plates 902 are connected by a first shaft 903. A support wheel 904 is sleeved on the first shaft 903. The two sides of the support wheel 904 are abutted against the inner side of the side plate 902 by a first spring 905.

[0033] The support wheel 904 on the reversing unit 9 constrains the direction of the power pipe 2. The support wheels 904 on multiple reversing units 9 cooperate with each other to achieve large-angle bending. At the same time, the support wheel 904 constrains the power pipe 2 to avoid the problem of overall jamming. Under the action of the first spring 905, it also achieves the function of center alignment, ensuring the stability of power transmission and making the vibrating head 1 work more efficiently.

[0034] In the preferred embodiment, a third through hole 810 is provided through the second clamping plate 806, the second shaft 808 is provided in the third through hole 810, and a first threaded hole 809 is provided on both sides of the first clamping plate 804. The angle adjustment unit 11 includes a locking rod 1101 and an angle plate 1105. The locking rod 1101 is fixed to the lower side of the third through hole 810. A locking plate 1106 is provided on the upper part of the angle plate 1105. The locking plate 1106 is fixed by screws 14 and the first threaded hole 809. An arc hole 1108 is provided through the angle plate 1105. A scale line 1109 is provided on one side of the arc hole 1108. The locking rod 1101 passes through the arc hole 1108, and the upper side of the locking rod 1101 is threaded with a locking sleeve 1110, which is pressed onto the angle plate 1105.

[0035] The angle plate 1105 and screw 14 on the angle adjustment unit 11 are installed on the first bracket 801, and the locking rod 1101 moves in the arc hole 1108. The angle of the second bracket 802 relative to the first bracket 801 is accurately obtained through the position of the locking rod 1101. The scale line 1109 provides intuitive angle data, which is convenient for construction personnel to make efficient adjustments.

[0036] In a preferred embodiment, a fourth through hole 1107 is provided through the locking plate 1106, and a screw 14 is provided in the fourth through hole 1107 and the first threaded hole 809. A support sleeve 1103 is provided on the locking rod 1101, and the support sleeve 1103 is supported on the lower part of the angle plate 1105. A slot 1102 is provided on the upper part of the locking rod 1101, and a pointer rod 1104 is inserted into the slot 1102. The pointer rod 1104 faces the scale line 1109. A protrusion 1111 is provided on the other side of the angle plate 1105, and the protrusion 1111 abuts against the lower part of the first clamping plate 804.

[0037] The angle gauge 1105 is accurately installed through the cooperation of the protrusion 1111 and the fourth through hole 1107. It will not move or rotate with the rotation of the second bracket 802. It is self-locking and stable. In addition, the pointer rod 1104 set on the locking rod 1110 is aligned with the scale line 1109, making the angle recognition more accurate and the viewing more convenient.

[0038] like Figure 17-20 In the preferred embodiment, the top of the vibrating head 1 is provided with a protrusion 101 and a frustum 102, the second through hole 103 is provided through the protrusion 101 and the frustum 102, the outside of the frustum 102 is provided with a groove 105, and the upper part of the frustum 102 is provided with an external thread 104. A connecting sleeve 1303 is provided at the lower part of the straight pipe 13. A first through hole 1301 is provided through the connecting sleeve 1303. An internal thread 1304 is provided at the lower part of the inner side of the connecting sleeve 1303. A second spring 1305 is provided at the top of the connecting sleeve 1303. The lower part of the second spring 1305 is located in the external thread 104. The power pipe 2 passes through the first through hole 1301, the second spring 1305 and the second through hole 103. An annular groove 1302 is provided on the upper outer side of the straight pipe 13. The inner side of the U-shaped clip 813 is attached to the outer wall of the annular groove 1302.

[0039] During the adjustment of the angles of the first support 801 and the second support 802, the power pipe 2 bends, causing a relative change in its position. Therefore, an annular groove 1302 is provided on the straight pipe 13 to provide some room for movement and prevent jamming. Furthermore, since the vibrating head 1 hangs down under gravity and is positioned at the top of the annular groove 1302, the groove controls the safe distance of the vibrating head 1, thus constraining it. Simultaneously, the U-shaped clip 813 is easy to install and remove. During installation, the frustum 102 fully extends into the mating sleeve 1303. Initially, under the constraint of the second spring 1305, the vibrator head 1 is locked in place. When the vibrator head 1 experiences external resistance and undergoes some axial movement, the upper side of the straight pipe 13 is fixed to the second bracket 802 by the U-shaped clip 813. The vibrator head 1, with the second spring 1305 acting as a buffer, achieves the process of force relief, preventing damage to the power pipe 2. Simultaneously, the entire system is easy to install and dismantle, has reliable sealing, and prevents concrete from entering the vibrator head 1 or the straight pipe 13, resulting in more stable overall operation.

[0040] like Figure 10-16In the preferred embodiment, the ranging unit 12 includes an adapter plate 1201, which is connected to a second bracket 802. A first baffle 1202 and a second baffle 1203 are symmetrically arranged on the upper side of the adapter plate 1201. The first baffle 1202 and the second baffle 1203 cooperate to form a locking cavity 1207. A servo motor 1211 is provided in the locking cavity 1207. A first gear 1212 is provided on the output shaft of the servo motor 1211. The first gear 1212 is meshed with a second gear 1213. The two sides of the second gear 1213 are connected to the first baffle 1202 through a first fixing rod 1209 and a second fixing rod 1210, respectively. The second fixing rod 1210 is connected to a fixing sleeve 1219 through a straight plate 1218. The infrared rangefinder 15 is inserted into the fixing sleeve 1219.

[0041] The locking cavity 1207 enables convenient installation and removal of the servo motor 1211. The servo motor 1211 adjusts its position according to the tilt angle of the handheld box 3 under the operator's usage habits and the angle of the second support 802 under the vibration requirements (such as tilted vibration scenario). In the initial state, the measurement direction of the infrared rangefinder 15 on the servo motor 1211 is parallel to the length direction of the second support 802. The servo motor 1211 has an angle encoder inside, so the rotation angle is accurate, and the infrared rangefinder 15 is vertically aligned with the concrete, thereby ensuring that the vertical distance is obtained. Then, the insertion depth of the vibrating head 1 is calculated by the angle of the second support 802 relative to the horizontal plane. The overall data acquisition is fast and accurate.

[0042] In a preferred embodiment, a sixth through hole 1206 is provided through the middle of the first baffle 1202, and the first fixing rod 1209 and the second fixing rod 1210 are inserted into the sixth through hole 1206. The sixth through hole 1206 is provided with a fifth through hole 1204 and a third threaded hole 1205 on both sides respectively. The insertion rod 1208 passes through the fifth through hole 1204 and is threadedly connected to the third threaded hole 1205. The outer side of the insertion rod 1208 is attached to the top of the servo motor 1211. A gap is provided between the second fixing rod 1210 and the servo motor 1211. The second gear 1213 has a first locking hole 1214 and a second locking hole 1215 on both sides respectively. The first fixing rod 1209 is threadedly connected to the first locking hole 1214, and the second fixing rod 1210 is threadedly connected to the second locking hole 1215. The second fixing rod 1210 has a through groove 1216, and through holes 1217 are provided on both sides of the through groove 1216. The straight plate 1218 is inserted into the through groove 1216, and the pin 1220 passes through the straight plate 1218 and the through hole 1217.

[0043] The entire assembly and disassembly is convenient, the operation of the second gear 1213 is undisturbed, and space utilization is higher. The straight plate 1218 serves as the supporting base for the fixing sleeve 1219. Under the control of the second gear 1213, the angle is accurately adjusted. Furthermore, due to the gap between the second fixing rod 1210 and the servo motor 1211, there is no friction between their surfaces, preventing friction-induced heat generation. The open design allows for timely heat dissipation, and the structure is compact. Additionally, individual components can be manufactured using 3D printing as needed, thereby reducing overall usage and maintenance costs, as well as the overall weight.

[0044] Example 2 Combined with appendix Figure 1 To further illustrate Example 1, the vibrator includes a vibrating head 1, a power tube 2, and a handheld box 3. The handheld box 3 contains a drive motor for generating high-frequency vibration. The vibrating head 1 is made of high-strength alloy steel to withstand the wear and impact of concrete.

[0045] Multiple sensor modules are integrated onto the vibratory rod to collect all key physical parameters of the vibration operation in real time. Specifically, these include: Pressure sensor 5: This sensor is miniaturized and embedded inside the tip of the vibratory head 1, with a range of 0.5–2.0 MPa. When the vibratory head 1 is inserted into the concrete, the pressure sensor 11 detects that the pressure value exceeds a preset threshold (e.g., 0.5 MPa) and sends a signal to the control module as the starting point for single-point vibration timing; when the vibratory head is pulled out and the pressure value drops back below the threshold, it is taken as the end point of timing.

[0046] Triaxial accelerometer 4: This sensor is installed at the connection between the vibrating head 1 and the power pipe 2 to directly sense the vibration state. Its vibration frequency detection range is 100–150Hz, and its amplitude detection range is 1.5–2.0mm. By analyzing the vibration data, the controller can calculate and monitor the effective range of the vibration action.

[0047] Infrared ranging sensor 15: This sensor is mounted on the power pipe 2, close to the vibrating head 1, and has a range of 0–2m. It faces the concrete surface and is used to measure the insertion depth of the vibrating head 1 relative to the initial concrete surface in real time, ensuring that the insertion depth meets the specifications.

[0048] The controller has an MCU for the control module, and the timer is integrated into the MCU of the control module. It records the time interval between the start signal and the end signal from the pressure sensor 5 with an accuracy of 0.1 seconds, which is the duration of single-point vibration.

[0049] The controller is embedded inside the handheld box 3. Its core includes an MCU controller and a storage module. The MCU controller is used to receive and process the data collected by the multi-dimensional sensor module.

[0050] The alarm unit is located on the surface of the handheld device 3, allowing the operator to directly observe and hear it. It includes a three-color LED indicator and a buzzer. The alarm unit is connected to the control module. When the vibration time is lower than the set lower limit or exceeds the set upper limit, an audible and visual alarm is triggered, manifested by a flashing red light and a buzzer sounding. When all vibration parameters meet the set standards, the green light illuminates, prompting the operator to proceed to the next position.

[0051] The handheld device 3 is equipped with a wireless transmission module, employing a dual-mode chip supporting Bluetooth 5.0 and NB-IoT. It connects to the MCU controller, uploading key data such as vibration time, insertion depth, vibration frequency, and amplitude in real time to an external mobile terminal or remote backend management system. Upon receiving the data, the backend management system automatically summarizes and generates a visual vibration quality distribution map. In this map, qualified vibration points are marked in green, insufficient vibration in yellow, and over-vibration in red, allowing managers to clearly understand the construction quality of the entire work area.

[0052] The power supply module uses a high-capacity, waterproof rechargeable lithium battery, integrated into a dedicated compartment at the rear of the handheld device. It provides stable power to the vibratory rod body, multiple sensor modules, control module, alarm unit, and wireless transmission module via internal circuitry, ensuring continuous operation of the equipment for at least one shift.

[0053] During concrete vibration compaction, the operator holds the handheld box 3 and inserts the vibrator head 1 into the concrete. The pressure sensor 5 senses the pressure and starts timing, while the infrared distance sensor 15 monitors the depth and the triaxial accelerometer 4 monitors the vibration status. The MCU controller 6 processes this data in real time and compares it with preset values. If any parameter exceeds the standard, an audible and visual alarm immediately alerts the operator. All data is uploaded wirelessly, forming construction records and quality maps, achieving full-process digital and intelligent management of the vibration operation. This fundamentally avoids the problems of over-vibration and under-vibration caused by traditional reliance on manual experience, significantly improving the homogeneity and overall quality of the concrete structure.

The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
