Description

Technical Field

[0001] This invention relates to the field of concrete construction equipment technology, specifically to a high-power, multi-point synchronous concrete vibration device. Background Technology

[0002] Concrete vibration refers to a construction technique in which mechanical vibration energy is transferred to the concrete during the concrete pouring process through vibrating equipment. This causes relative movement within the concrete, thereby expelling air, reducing voids, and improving the density and uniformity of the concrete. Vibration allows the concrete to flow better under its own weight and fill all corners of the formwork, avoiding defects such as honeycomb, pitting, and voids. It also improves the strength, durability, and overall quality of the concrete. Concrete vibration typically uses equipment such as immersion vibrators, attached vibrators, or plate vibrators. The appropriate vibration method and vibration time are selected based on the type and thickness of the concrete and the construction environment to ensure the best vibration effect.

[0003] Chinese patent CN219344057U discloses a concrete vibrator. This concrete vibrator starts by inserting a vibrating rod into the concrete. During the vibration of the vibrating rod, the vibrating sleeve vibrates synchronously. Air bubbles at the bottom of the concrete escape through the second through hole, the hollow cavity between the vibrating sleeve and the vibrating rod, and the first through hole. The concrete slurry formed during the vibration flows back to the deep layers of the concrete through the first through hole, the hollow cavity, and the second through hole, thereby improving the uniformity of concrete vibration mixing, reducing the residual air bubbles in the concrete, and improving the concrete vibration treatment effect.

[0004] Existing concrete vibrators generally rely on external power sources, making it difficult to operate normally and efficiently at construction sites without or with insufficient power. At the same time, traditional vibrators are mostly single-bar or low-power structures, resulting in low vibration efficiency and difficulty in achieving large-area, multi-point synchronous operation, which limits the operating range and fails to meet the needs of rapid construction and large-area concrete pouring. Summary of the Invention

[0005] The purpose of this invention is to provide a high-power, multi-point synchronous concrete vibration device to solve the problems of existing vibrators being dependent on power sources, having low efficiency, and being unable to perform large-area synchronous vibration.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] (1) This invention utilizes the coordinated operation of a diesel tractor, a lifting mechanism, a diesel generator, a vibration mechanism, and a control cabinet. The diesel generator provides independent power, eliminating the dependence on external power sources. Multiple high-power vibration mechanisms enable large-area, multi-point synchronous vibration operations, significantly improving construction efficiency.

[0024] (3) The present invention achieves reliable rigid fixation of the vibratory rod in the transportation state and flexible limit of the flexible shaft in the working state through the coordinated work of the clamping mechanism and the vibration mechanism. The adaptive dual-mode design of the clamping mechanism not only ensures the safety of equipment movement, but also effectively prevents the flexible shaft from winding, colliding and abnormal swinging, ensuring that the vibratory rod can transmit stable vibration force in different positions, and extending the service life of key components while ensuring the vibration effect.

[0036] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] As attached Figure 1 To be continued Figure 8 As shown:

[0038] Example 1:

[0039] This invention provides a high-power, multi-point synchronous concrete vibration device, including a diesel tractor 1. The diesel tractor 1 has been modified to reduce its speed, with the travel speed controlled at about 6-8 meters per minute, which can fully meet the requirements for concrete vibration and compaction. It also uses small-tread tires to effectively avoid indentations on the cast-in-place concrete and maximize the flatness of the concrete pouring. The diesel tractor 1 is equipped with a seat, a steering wheel, and two sets of control levers. One set is the tractor's own travel control lever, and the other set is a dedicated control lever for the lifting mechanism 2. The operator can precisely control the lifting and lowering actions of the lifting mechanism 2 through the dedicated control lever.

[0040] Lifting mechanism 2 is installed on one side of the top of the frame of diesel tractor 1;

[0041] The lifting mechanism 2 includes a support adjustment frame 21, two ear plate mounting frames 22, a telescopic drive assembly 23, multiple limiting mechanisms 24, multiple clamping mechanisms 25, and a distance sensor 26. The support adjustment frame 21 is movably mounted on the outer wall of the diesel tractor 1 frame via a connecting shaft. The high-strength connecting shaft is equipped with anti-detachment pins and lubricating bearings at both ends, enabling the support adjustment frame 21 to rotate flexibly at multiple angles and ensuring that it is not prone to jamming during long-term operation. The two ear plate mounting frames 22 are respectively mounted on the upper and lower sides of the outer wall of the telescopic drive assembly 23, and the top of the upper ear plate mounting frame 22 is mounted on the support adjustment frame 21. The ear plate mounting frame 22 is detachable, which facilitates later maintenance and component replacement. Multiple limiting mechanisms 24 are all located at the top of the support adjustment frame 21. Multiple clamping mechanisms 25 are all located on the right side of the outer wall of the support adjustment frame 21. The distance sensor 26 is mounted on the lower side of the middle of one end of the support adjustment frame 21, which has dustproof and waterproof functions, is suitable for harsh construction environments, and can accurately monitor the distance to the working surface.

[0042] Diesel generator 3 is installed at the top center of the diesel tractor 1 frame and is fixedly installed by a vibration damping bracket to reduce vibration transmission during operation. Diesel generator 3 is set to 30kW.

[0043] Multiple vibration mechanisms 4 are all installed on the lifting mechanism 2. Each vibration mechanism 4 is equipped with an independent switch, which can be fully opened, intermittently opened, or partially opened. Operators can flexibly adjust the vibration point and power according to the construction conditions.

[0044] Control cabinet 5 is installed on the lower side of the outer wall of lifting mechanism 2 and is fixedly installed by an insulating plate. The cabinet is equipped with a dustproof heat dissipation grille and a waterproof sealing gasket.

[0045] The diesel generator 3 is electrically connected to the vibratory motor 41, the telescopic drive assembly 23, the distance sensor 26, and the control cabinet 5 via wires, which can eliminate the dependence on external power supply. The wires are covered with protective sleeves to prevent wear and leakage during construction. The operating status of the vibratory motor 41, the telescopic drive assembly 23, and the distance sensor 26 is controlled by the control cabinet 5. The control cabinet 5 has a built-in PLC control system, which can preset vibration parameters and realize automated operation, ensuring that the operation of each component is coordinated and unified.

[0046] Working Principle: This device uses a diesel tractor 1 as a mobile and carrying platform, powered by its onboard diesel generator 3. The generator 3 provides independent power, eliminating reliance on external power sources. Combined with multiple high-power vibration mechanisms 4, it achieves large-area, multi-point synchronous vibration operations, significantly improving construction efficiency. During operation, operators can flexibly adjust the opening mode of each vibration mechanism 4 according to the construction area and concrete pouring thickness using independent switches. It can be fully open, intermittently open, or partially open. Vibration parameters are set via the control cabinet 5, which then instructs the telescopic drive assembly 23 to raise and lower the support adjustment frame 21 via the ear plate mounting bracket 22. This adjusts the height of the multiple vibration mechanisms 4 mounted above the support adjustment frame 21. A distance sensor 26 mounted on the lower side of the support adjustment frame 21 monitors the distance to the concrete surface in real time and feeds the signal back to the control cabinet 5. The telescopic drive assembly 23 is fine-tuned using a closed-loop control method to ensure accurate insertion depth of the vibrator 43. Simultaneously, the control cabinet 5... The corresponding vibration motor 41 is set to start, and the power is transmitted to the vibrating rod 43 at the end through the flexible shaft 42, causing it to generate high-frequency vibration and insert into the concrete, realizing multi-point and efficient vibration of large-area concrete. The diesel tractor 1 moves at a low speed of 6-8 meters per minute, and the small-tread tires avoid causing indentations to the cast-in-place concrete, ensuring the compaction of the concrete while maximizing the flatness of the concrete surface. During the vibration process, multiple limiting mechanisms 24 are used to constrain and straighten the direction of each flexible shaft 42 to prevent entanglement, while multiple clamping mechanisms 25 set on the right side of the support adjustment frame 21 fix the vibrating rod 43 in the non-operation state to ensure stability during transportation and movement. This concrete vibration device, with the mobility of the diesel tractor 1 and the height adjustment function of the lifting mechanism 2, can adapt to the vibration depth requirements of different pouring scenarios, meeting the needs of rapid construction and large-area concrete pouring, and improving the adaptability of the device in the field or in construction sites without electricity, further enhancing the overall construction efficiency.

[0047] Example 2:

[0048] This embodiment is basically the same as the previous embodiment, except that the support adjustment frame 21 includes a fixed tube 211, a support frame 212, two support rods 213, a mounting rod 214, four reinforcing rods 215, two support plates 216, and a mounting plate 217. The support frame 212 is installed at the bottom end of the fixed tube 211. The two support rods 213 are respectively installed on both sides of the bottom end of the support frame 212. The mounting rod 214 is installed between the right sides of the bottom end of the two support rods 213. The four reinforcing rods 215 are respectively installed in pairs at the top of the two support rods 213 and are symmetrically and obliquely welded between the top of the two support rods 213 and the outer wall of the support frame 212 to form a triangular stable structure, which improves the overall deformation resistance. The two support plates 216 are respectively installed on the left side of the top of the two support rods 213, and the mounting plate 217 is installed between the top of the two support plates 216.

[0049] The limiting mechanism 24 includes a limiting frame 241, two threaded grooves 242, two limiting nuts 243, and two buffer sleeves 244. The limiting frame 241 is movably inserted through the top of the fixed tube 211. The two threaded grooves 242 are both opened on the lower side of the outer wall of the limiting frame 241. The two limiting nuts 243 are threadedly installed on the lower side of the outer wall of the limiting frame 241, and the height of the limiting frame 241 is adjusted in conjunction with the threaded grooves 242. The two buffer sleeves 244 are respectively sleeved on both sides of the outer wall of the limiting frame 241, and the outer wall of the buffer sleeve 244 is fixedly connected to the inner wall of the mounting hole of the fixed tube 211.

[0050] The fixed tube 211 has multiple mounting holes, which provide an assembly base for the limiting mechanism 24. The support frame 212 is set as an H-shaped structure, and the two support plates 216 are set as triangular structures. The H-shaped structure and the triangular structure utilize geometric stability to improve the overall rigidity and anti-deformation capacity of the support adjustment frame 21, ensuring load-bearing reliability. The fixed tube 211, support frame 212, support rod 213, mounting rod 214, reinforcing rod 215, support plate 216 and mounting plate 217 of the support adjustment frame 21 are all fixedly connected by welding. Welding achieves rigid fixation of each component, forming an integrated frame, avoiding loosening when multiple vibration mechanisms 4 operate synchronously, ensuring stable transmission of vibration energy and safe operation of the equipment.

[0051] The limiting frame 241 is designed with a U-shaped structure to accommodate the layout and constraint of the flexible shaft 42. The limiting nut 243 has a rubber sleeve on the outer wall of the limiting frame 241 facing the buffer sleeve 244. The buffer sleeve 244 is made of rubber. The rubber sleeve and the rubber buffer sleeve 244 can absorb vibration and isolate impact, prevent the limiting frame 241 from rigidly colliding with the fixed tube 211, and protect the flexible shaft 42 and the limiting mechanism 24 itself.

[0052] Working Principle: The support adjustment frame 21, constructed by welding together a fixed pipe 211, an H-shaped support frame 212, a support rod 213, a mounting rod 214, a reinforcing rod 215, a triangular support plate 216, and a mounting plate 217, forms a stable and adjustable support frame for the vibration mechanism 4. This provides a centralized mounting foundation and rigid support for multiple vibration mechanisms 4, and also provides a stable rigid support frame for the entire lifting mechanism 2. Each vibration mechanism 4 is equipped with an independent switch, allowing for full opening, interval operation, or partial opening. Its vibration motor 41 is centrally mounted on the mounting plate 217, and the generated vibration is transmitted to the vibrator 43 via a flexible shaft 42. During operation, the operator first adjusts the opening mode of the vibration mechanism 4 according to the working conditions, and then activates the telescopic drive assembly 23 through the control cabinet 5. This drives the support adjustment frame 21 to move up and down around its connection axis with the diesel tractor 1 frame, thereby synchronously adjusting the working height of all the opened vibration mechanisms 4. The diesel tractor 1 moves at a low speed of 6-8 meters per minute. The tire tread effectively avoids indentations on the cast-in-place concrete, adapting to the process requirements of vibration compaction. During this process, the flexible shaft 42 passing through the top of the fixed tube 211 is constrained and protected by the limiting mechanism 24. The U-shaped limiting frame 241 passes through the mounting hole on the fixed tube 211 to limit the flexible shaft 42, which can flexibly adjust and lock the layout position of the flexible shaft 42. It is then fixed by tightening the limiting nut 243. The rubber buffer sleeves 244 on both sides can effectively absorb and isolate the vibration transmitted by the flexible shaft 42, preventing rigid collision and wear between the limiting frame 241 and the fixed tube 211. This ensures the structural reliability and effective transmission of vibration energy when multiple vibration units operate synchronously under high load, improving the stability and service life of the equipment. At the same time, the mounting rod 214 on the right side of the support adjustment frame 21 provides a mounting base for multiple clamping mechanisms 25. It can fix the vibrator 43 in the non-operating state or form a flexible limit on the flexible shaft 42 in the operating state, ensuring reliable high-power, multi-point synchronous vibration operation.

[0053] Example 3:

[0054] This embodiment is basically the same as the previous embodiment, except that the clamping mechanism 25 includes a fixed base 251, a mounting groove 252, two limiting grooves 253, a positive and negative screw 254, and a limiting rod 255. The mounting groove 252 is opened on one side of the bottom end of the fixed base 251. The fixed base 251 is installed on the outer wall of the mounting rod 214 through the mounting groove 252. Both limiting grooves 253 are opened on the top of the fixed base 251. The positive and negative screw 254 is installed between the inner walls of the two sides of one of the limiting grooves 253 through a bearing. The bearing is equipped with a dust cover to reduce dust entry. The limiting rod 255 is installed between the inner walls of the two sides of the other limiting groove 253.

[0055] The clamping mechanism 25 also includes two clamping plates 256, two clamping slots 257, two adjusting handles 258, and three protective sleeves 259. The two clamping plates 256 are slidably installed between the two limiting slots 253, and the clamping plates 256 are threadedly connected to the positive and negative screws 254 and slidably connected to the limiting rods 255. The two clamping slots 257 are respectively opened in the middle of the opposite surfaces of the two clamping plates 256. The two adjusting handles 258 are respectively installed at both ends of the positive and negative screws 254. The three protective sleeves 259 are all sleeved on the outer wall of the positive and negative screws 254, covering the key transmission parts of the screws.

[0056] The vibration mechanism 4 includes a vibration motor 41, a flexible shaft 42, and a vibrating rod 43. The vibration motor 41 is mounted on the top of the mounting plate 217. The motor housing is made of aluminum alloy, which is lightweight and has excellent heat dissipation performance. The flexible shaft 42 is mounted on the output end of the vibration motor 41. The flexible shaft 42 is mounted on the fixed tube 211 through the limiting mechanism 24 and on the mounting rod 214 through the clamping mechanism 25. The double limiting ensures that the flexible shaft 42 does not move during the vibration process. The vibrating rod 43 is mounted on the other end of the flexible shaft 42 away from the vibration motor 41. The vibrating rod 43 is set to 3000 watts.

[0057] The clamping groove 257 is designed with a V-shaped structure, which can accommodate vibrating rods 43 of different diameters. It also utilizes the inclined plane self-locking principle to improve clamping stability, ensuring reliable clamping whether for flexible limiting during operation or rigid fixing during transport. Three protective sleeves 259 are respectively fitted onto the outer walls of the positive and negative screws 254 on both sides and the middle. The protective sleeves 259 are designed with a foldable dustproof structure, their outer walls fitting the inner walls of the limiting groove 253. The foldable structure can flexibly extend and retract with the rotation of the positive and negative screws 254 without interfering with transmission. This provides full coverage installation and compatibility with the limiting groove. The adaptability of the slot 253 can effectively isolate dust and mud in the construction environment, avoid wear of the screw drive pair, and extend service life. The clamping plate 256 is provided with a protrusion that matches the limiting slot 253. The matching relationship between the protrusion and the limiting slot 253 can guide the clamping plate 256 to slide smoothly along the preset trajectory, avoid deviation or jamming, and ensure the synchronous movement and clamping accuracy of the two clamping plates 256. The fixing seat 251 is set as a triangular structure. By utilizing the geometric stability of the triangle, the anti-shaking ability of the fixing seat 251 after being connected to the mounting rod 214 is improved.

[0058] Working principle: Before operation, the operator adjusts the opening mode through the independent switches of each vibration mechanism 4 according to the working conditions. It can be fully opened, opened at intervals, or half-opened. Then, manually rotate the adjusting handle 258 to drive the positive and negative screw rod 254 to rotate, and further drive the two clamping plates 256 that are slidably nested in the limiting groove 253 to make precise moving in the same or opposite directions along the limiting rod 255, and the opening distance of the V-shaped clamping groove 257 is adjusted accordingly; when the device is in the transportation or standby state, the clamping plates 256 are fully closed to rigidly clamp and fix the rod body of the vibrating rod 43, ensuring safe movement. During the vibrating operation, the operator adjusts the clamping plates 256 to the preset working distance, takes out the vibrating rod 43, and inserts the flexible shaft 42 into the clamping mechanism 25. At this time, a loose guiding channel with a buffer gap is formed between the inner wall of the V-shaped clamping groove 257 and the outer wall of the flexible shaft 42. After the vibrating rod 43 and the flexible shaft 42 are inserted into the concrete, they can freely perform axial lifting and high-frequency radial vibration, and excessive lateral swing can be effectively restricted by this channel, thereby preventing multiple flexible shafts 42 from winding around each other or colliding with the surrounding structures; during the operation process, the diesel tractor 1 moves at a low speed of 6 - 8 meters per minute to meet the requirements of vibrating compaction, and small-tread tires are used to avoid indentation on the cast-in-place concrete to the greatest extent and ensure the pouring flatness; this design not only ensures that the vibrating rod 43 can transmit stable vibration force at different positions and guarantee the uniformity of vibrating effect, but also extends the service life of key components, while improving the operation convenience and maintenance convenience of the equipment. The three folding protective sleeves 259 expand and contract synchronously with the movement of the positive and negative screw rod 254, effectively isolating dust and mud and protecting the screw transmission pair; in addition, all the activated vibration motors 41 are centrally installed on the mounting plate 217 and synchronously controlled by the control cabinet 5 to achieve precise synchronization of centralized power and multi-point vibration. The distance sensor 26 real-time feeds back the height information for closed-loop control of the insertion depth. Finally, through the adaptive dual-mode design of the clamping mechanism 25 with rigid fixation during transportation and flexible limiting during operation, on the premise of fully retaining its structural integrity, the vibration transmission components are effectively managed without interfering with its core vibrating function.

Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention.
