Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of building construction, and more particularly relates to a double-power-head cooperative construction device for vibroflotation and sand compaction piles. BACKGROUND

[0002] The vibroflotation and sand compaction pile is a kind of vibroflotation pile, mainly used for soft clay foundation. After the hole is formed by vibroflotation, coarse particle materials such as gravel and pebbles are backfilled into the hole to form a dense gravel pile body. The main function is to replace part of the soft soil to form a composite foundation, improve the bearing capacity and reduce the settlement.

[0003] According to the search of the Chinese patent with the announcement number CN118932970A, a device for increasing the soil cutting efficiency of a vibroflotation and sand compaction pile vibrator is disclosed. The device sprays high-pressure liquid through a ball to cut the stone, so that the vibroflotation pipe can continue to move downward. In this way, when encountering abnormally hard deep sand, the high-pressure liquid can be sprayed through the ball to cut, thereby speeding up the construction efficiency.

[0004] Based on the above search and the existing technology, it is found that the above-mentioned patent has certain defects. When the above-mentioned vibroflotation pile is used, the high-pressure liquid is sprayed through the ball to cut the stone when it encounters abnormally hard deep sand, which can improve the efficiency to a certain extent. However, this construction method is single-pile vibroflotation, and the vibroflotation efficiency is low. In addition, when the size of the vibroflotation pit changes, the vibroflotation pile needs to be replaced, which has poor applicability and needs to be improved. SUMMARY

[0005] In order to solve the above technical problems, the application provides a double-power-head cooperative construction device for vibroflotation and sand compaction piles to solve the above problems.

The rotation of each double-thread rod can move through the thread transmission between the internal thread groove and the sliding plate.

The limiting ring is located above the second lifting ring, the IMU sensor is on the same side as the limiting ring, the extension length of the limiting ring is greater than the length of the second lifting ring, and a connecting plate is symmetrically fixedly installed between the two fixed plates.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, by turning on the motor to drive the bidirectional threaded rod to rotate, the internal thread groove and the sliding plate will undergo precise thread transmission, which will drive the connecting ring to move in both directions of the vibratory compaction sand pile body, thereby realizing stepless adjustment of the spacing between the two piles, adapting to the different reinforcement needs of different vibratory compaction pits, avoiding the time-consuming manual disassembly and assembly, and improving convenience.

[0014] In this invention, by setting two vibratory compaction sand pile bodies on the coordinated adjustment structure, the double-moving piles can be simultaneously driven into the soil layer during construction. Combined with the sand and water injection through the delivery pipe, the construction efficiency and pile quality can be greatly improved.

[0015] In this invention, by arranging moving gyroscopes at the four corners of the fixed plate and combining them with IMU sensors, when the steel cable of the lifting device sways due to the synchronous vibration of the two vibratory compaction sand pile bodies, the phase difference between the two piles can be eliminated by the moving gyroscopes, thus eliminating vibration wave interference, avoiding uneven sand liquefaction, and further improving the vibratory compaction effect.

[0016] In this invention, by connecting the first lifting ring, the limiting ring, and the second lifting ring in series with the lifting equipment, and in conjunction with the IMU sensor and the four-corner moving gyroscope, the three-axis attitude angle and vibration spectrum of the fixed plate are detected in real time, thereby realizing anti-overturning control throughout the construction process, eliminating the pile tilting problem caused by hoisting sway, and improving reliability;

[0027] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0028] Please see Figures 1-8 This invention provides a dual-power head collaborative construction device for vibratory compaction sand piles, comprising two fixing plates 11, each with a through groove 12 extending through its interior, and symmetrical sliding grooves 14 formed on the side walls of each fixing plate 11.

[0029] A coordinated adjustment structure is fixedly installed at the center point inside each set of slides 14;

[0030] The coordinated adjustment structure includes a partition plate 13, a bidirectional threaded rod 15 rotatably installed inside each slide groove 14, and motors 16 symmetrically fixed on the side walls of two fixed plates 11. The output shaft of each motor 16 is fixedly installed with the bidirectional threaded rod 15. The start of the output shaft of each motor 16 can drive the bidirectional threaded rod 15 to rotate inside the slide groove 14. Both bidirectional threaded rods 15 are rotatably installed with the partition plate 13. Sliding plates 17 are symmetrically slidably installed between each set of slide grooves 14. Each sliding plate 17 has symmetrically opened internal threaded grooves 18. Each internal threaded groove 18 is threadedly installed with the bidirectional threaded rod 15. The rotation of each bidirectional threaded rod 15 can be moved by the threaded transmission between the internal threaded groove 18 and the sliding plate 17.

[0031] By turning on the motor 16 to drive the bidirectional threaded rod 15 to rotate, the internal threaded groove 18 and the sliding plate 17 will undergo precise thread transmission, which will drive the connecting ring 19 to move the vibratory compaction sand pile body 21 in both directions, thereby realizing stepless adjustment of the spacing between the two piles, adapting to the differentiated reinforcement needs of different vibratory compaction pits, avoiding time-consuming manual disassembly and assembly, and improving convenience.

[0032] Each internal thread groove 18 is fixedly installed with a connecting ring 19. Each set of connecting rings 19 is provided with a vibratory compaction sand pile body 21. The lower end of each vibratory compaction sand pile body 21 is provided with a moving pile 22. The side wall of each vibratory compaction sand pile body 21 is provided with a conveying pipe 23.

[0033] By setting two vibratory compaction sand pile bodies 21 on the coordinated adjustment structure, the double-moving piles 22 can be driven into the soil layer simultaneously during construction. With the sand and water grouting from the delivery pipe 23, the construction efficiency and pile quality can be greatly improved.

[0034] Both conveying pipes 23 are located above the fixed plate 11. The upper ends of the two vibratory compaction sand pile bodies 21 are provided with first lifting rings 24. The four corners of the two fixed plates 11 are provided with storage slots 25. Each storage slot 25 is provided with a moving gyroscope 26. An IMU sensor 27 is symmetrically fixedly installed on the upper end of one of the fixed plates 11 (the motor 16, the moving gyroscope 26 and the IMU sensor 27 are controlled by an external PLC controller). The side walls of the two fixed plates 11 are symmetrically fixedly installed with second lifting rings 28 and limit rings 29 respectively. The limit ring 29 is located above the second lifting ring 28. The IMU sensor 27 is on the same side as the limit ring 29. The extension length of the limit ring 29 is greater than the length of the second lifting ring 28. A connecting plate 31 is symmetrically fixedly installed between the two fixed plates 11.

[0035] By arranging moving gyroscopes 26 at the four corners of the fixed plate 11 and combining them with IMU sensors 27, when the steel cable of the lifting device sways due to the synchronous vibration of the two vibratory compaction sand pile bodies 21, the phase difference between the two piles can be eliminated by the moving gyroscopes 26, the vibration wave interference can be eliminated, the problem of uneven liquefaction of sand can be avoided, and the vibratory compaction effect can be further improved.

[0036] By connecting the first lifting ring 24 with the limiting ring 29 and the second lifting ring 28 in series with the lifting equipment, and with the help of the IMU sensor 27 and the four-corner moving gyroscope 26, the three-axis attitude angle and vibration spectrum of the fixed plate 11 are detected in real time, thereby realizing anti-overturning control throughout the construction process, eliminating the pile tilting problem caused by hoisting sway, and improving reliability;

[0037] By setting a limit ring 29, and ensuring that the extension length of the limit ring 29 is greater than the length of the second hanging ring 28, excessive swing can be physically intercepted. Furthermore, by arranging the moving gyroscope 26 at the four corners and combining it with the IMU sensor 27, dual-insurance control can be achieved for high-risk working conditions, thereby improving overall stability.

[0038] Working principle:

[0039] In the first step, when in use, the operator can turn on the motor 16, so that the output shaft of the motor 16 drives the bidirectional threaded rod 15 to rotate inside the slide groove 14, so that the slide groove 14 and the internal thread groove 18 of the sliding plate 17 are threadedly driven, so that each set of sliding plates 17 on the inner side of the two fixed plates 11 drives the vibratory compaction sand pile body 21 to move away from or closer to each other through the connecting ring 19, thereby adjusting the distance between the two vibratory compaction sand pile bodies 21 to adapt to different processing vibratory compaction pits;

[0040] The second step involves the operator first connecting the lifting device to the two first lifting rings 24 using a crane. Simultaneously, the lifting device needs to be connected to the second lifting ring 28 below the limit ring 29 to complete the installation. Then, the operator can use the lifting device to move the entire device. The IMU sensor 27 monitors the three-axis attitude angles (pitch, roll, yaw) of the fixed plate 11 in real time, detecting the instantaneous angular velocity changes at the edge of the fixed plate 11. At the same time, the array of moving gyroscopes 26 in the four corner storage slots 25 is activated synchronously to keep the fixed plate 11 in a horizontal state and prevent swaying. Then, the operator can activate the moving pile 22 of the vibratory compaction sand pile body 21 to drive the soil layer to the design depth. Simultaneously, sand (requiring an external sand pump) and water are injected through the delivery pipe 23. The vibratory compaction sand pile body 21 vibrates at high frequency, squeezing the surrounding sand and soil, and filling the sand to form a dense pile body, thus completing the processing.

Many modifications and variations will be apparent to those skilled in the art.
