Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an automated stress adjustment device for anchor piles used in basement structural reinforcement. Background Technology

[0002] In basement structural reinforcement projects, anchor piles serve as critical supporting components, and their stress state directly impacts the overall structural safety. Existing technologies for anchor pile jacking equipment primarily employ fixed hydraulic systems, making it difficult to dynamically adjust the jacking force based on real-time stress changes in the pile. This can easily lead to uneven stress distribution on the pile or excessive energy consumption. Furthermore, traditional equipment lacks a self-locking mechanism, requiring continuous pressure supply to maintain the jacking rod position, increasing energy consumption and potentially causing safety hazards due to hydraulic fluctuations. Additionally, adjusting the jacking height requires manual disassembly of positioning components, a cumbersome and inefficient process. In terms of monitoring, traditional equipment relies heavily on manual inspections, making it impossible to obtain real-time data on key parameters such as pile stress and strain, hindering the timely detection of potential risks.

[0003] Therefore, developing a stress adjustment device for anchor piles that can monitor the pile condition in real time, automatically adjust the jacking force, and reduce energy consumption has significant engineering application value. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing anchor pile stress automatic adjustment devices for basement structure reinforcement, which are difficult to dynamically adjust the jacking force according to the real-time stress changes of the pile, lack a self-locking mechanism, and require manual disassembly of positioning components when adjusting the jacking height.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] In one possible design, the self-locking structure includes a base fixedly connected to the top of the pressure plate, a positioning rod sliding through the base, and multiple slots arranged longitudinally around the outer periphery of the hydraulic cylinder push rod; a first fixing plate is fixedly connected to the end of the positioning rod away from the hydraulic cylinder, and a tension spring is provided between the first fixing plate and the base, with the two ends of the tension spring fixedly connected to the first fixing plate and the base respectively through spring seats, and the tension spring is sleeved around the outer periphery of the positioning rod.

[0011] In one possible design, the self-locking structure further includes a sliding ring slidably sleeved on the outer periphery of the protective ring, and multiple U-shaped rods fixedly connected to the top of the sliding ring; multiple first fixing plates are fixedly connected to a second fixing plate on the side away from the positioning rod, the second fixing plate is provided with an inclined groove, and a pin is slidably connected in the inclined groove, the pin being fixedly connected in the corresponding U-shaped rod.

[0012] In one possible design, a linkage structure is also included; the linkage structure includes a sliding groove disposed in the crossbeam, a sliding rod slidably connected in the sliding groove, a movable cylinder slidably connected to the top of the pressure plate, a push rod fixedly connected to one side of the movable cylinder, and a trapezoidal rod fixedly connected to one side of the sliding ring; the sliding rod is fixedly connected to one of the insert rods, the bottom end of the sliding rod is slidably inserted into the movable cylinder, and the push rod is slidably engaged with the inclined surface of the trapezoidal rod.

[0013] In one possible design, the bottom of the base is fixedly connected to multiple hydraulic leveling legs, all of which are connected to a hydraulic pump station via oil pipes; a tilt sensor is fixedly connected to the bottom of the base.

[0014] In one possible design, a fiber optic grating sensor is installed inside the anchor pile; wherein the fiber optic grating sensor monitors the stress parameters of the anchor pile in real time, and the hydraulic pump station adjusts the jacking force of the hydraulic cylinder according to the monitoring data.

[0015] In one possible design, the hydraulic cylinder has a pressure sensor at its oil port, which is connected to an oil pipe; the pressure sensor detects the hydraulic cylinder oil pressure in real time so as to adjust the thrust force in conjunction with the data from the fiber optic grating sensor.

[0016] In one possible design, the bottom of the positioning rod near the hydraulic cylinder has a second inclined surface; the top of the pressure plate is fixedly connected to a slide rail, and the moving cylinder is slidably connected to the slide rail.

[0017] Beneficial effects: In this invention, a fiber optic grating sensor is installed inside the anchor pile, and the hydraulic cylinder is connected to the hydraulic pump station via an oil pipe; the fiber optic grating sensor is connected to an external control center via a wireless transmission module, which is used to monitor the stress, strain, and temperature of the anchor pile in real time when the anchor pile is pushed to the ground, so as to facilitate the subsequent adjustment of the pushing force applied by the hydraulic cylinder by the hydraulic pump station, ensuring that the anchor pile is always in the best working condition and timely detection of potential safety hazards;

[0018] In this invention, a positioning rod slides through the base, and a first fixing plate is fixed to the end of the positioning rod away from the hydraulic cylinder. A tension spring is provided on the side of the first fixing plate that is close to the base. Both ends of the tension spring are fixedly connected to the first fixing plate and the base through spring seats. When the push rod of the hydraulic cylinder extends, the positioning rod always abuts against the outer wall of the push rod of the hydraulic cylinder under the tension of the tension spring. When the positioning rod is aligned with the slot, the positioning rod is inserted into the slot under the action of the tension spring, thus locking the push rod of the hydraulic cylinder and reducing the operating loss of the hydraulic pump station when maintaining the push rod of the hydraulic cylinder at rest.

[0019] In this invention, a rotating plate is fixed to the outer wall of the rotating shaft, and connecting rods are rotatably connected to both sides of the bottom of the rotating plate. The ends of the two connecting rods that are far apart from each other are rotatably connected to the tops of the two insert rods respectively. The rotating shaft and the rotating plate are driven to rotate by the rotating column and the crank. The rotating plate pulls the insert rods towards the middle through the connecting rods. The insert rods disengage from the pin grooves, releasing the frame from the crossbeam. This allows the height of the crossbeam to be controlled, which is convenient for applying a jacking force to the anchor pile body in cooperation with the hydraulic cylinder later.

[0020] In this invention, a sliding rod is slidably connected within the sliding groove, and the sliding rod is fixedly connected to one of the insert rods. A movable cylinder is slidably connected to the top of the pressure plate, and the sliding rod extends slidably into the movable cylinder. A push rod is fixed to the side of the movable cylinder near the hydraulic cylinder, and a trapezoidal rod is fixed to one side of the sliding ring. When the insert rod disengages from the pin groove, it pushes the movable cylinder and the push rod towards the center via the sliding rod. The push rod, in cooperation with the trapezoidal rod, drives the slot and the U-shaped rod to move downwards. The U-shaped rod, through the cooperation of the pin and the inclined groove, drives the positioning rod to move outwards, thereby releasing the locking of the positioning rod to the hydraulic cylinder push rod. When the hydraulic cylinder push rod retracts, it can drive the crossbeam to move downwards, facilitating subsequent jacking of the anchor pile. The operation is simple and the jacking efficiency is improved.

[0021] In this invention, the adjustment device effectively solves the problems existing in the prior art through technologies such as automated control, reliable self-locking, deformation compensation, linkage operation, leveling function, and real-time monitoring and feedback, and improves the quality and efficiency of anchor pile stress adjustment. This device can provide strong protection for the safety and stability of basement structures in basement structure reinforcement projects. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] In one embodiment: Refer to Figure 1 and Figure 2 The equipment, relating to the field of building construction technology, mainly includes a base 1 and an anchor pile body 3. A frame 2 is welded and fixed to the top of the base 1, and a crossbeam 8 and a pressure plate 17 are slidably connected from top to bottom inside the frame 2. The pressure plate 17 is placed on top of the anchor pile body 3 to apply a jacking force to the anchor pile body 3.

[0034] Reference Figure 4 and Figure 5 A positioning structure is provided between the frame 2 and the crossbeam 8 to release the brake between the crossbeam 8 and the frame 2 when needed, so as to adjust the height of the crossbeam 8. The positioning structure includes two connecting rods 13 sliding on the top of the crossbeam 8 and a rotating shaft 10 rotating on the top of the crossbeam 8. A rotating plate 11 is fixedly sleeved on the outer wall of the rotating shaft 10, and a torsion spring 12 is also sleeved on the outer wall of the rotating shaft 10. The top and bottom ends of the torsion spring 12 are fixedly connected to the bottom of the rotating plate 11 and the top of the crossbeam 8 respectively through spring seats, for driving the rotating plate 11 to reset. Connecting rods 13 are rotatably connected to both sides of the bottom of the rotating plate 11, and the ends of the two connecting rods 13 that are far apart from each other are rotatably connected to the tops of two insert rods 9 respectively. Multiple pin slots 14 are provided on the inner walls of the two sides of the frame 2 that are close to each other, and the pin slots 14 are engaged with the insert rods 9 for positioning the crossbeam 8. A crank 15 is fixed to the top of the rotating shaft 10, and a rotating column 16 is rotatably connected to one side of the top of the crank 15, which facilitates driving the rotating shaft 10 and the rotating plate 11 to rotate.

[0035] In actual operation, when the height of the crossbeam 8 needs to be adjusted, the operator can drive the crank 15 and the rotating shaft 10 to rotate via the rotating column 16. The rotating shaft 10 drives the rotating plate 11 to rotate, and the rotating plate 11 pulls the insert rod 9 towards the center via the connecting rod 13, causing the insert rod 9 to disengage from the pin groove 14, thereby releasing the jamming between the frame 2 and the crossbeam 8. At this time, the operator can move the crossbeam 8 up and down to the desired position, then release the rotating column 16, the torsion spring 12 drives the rotating plate 11 to reset, and the insert rod 9 is reinserted into the corresponding pin groove 14, completing the positioning of the crossbeam 8.

[0036] Reference Figure 2 and Figure 6 A hydraulic cylinder 18 is fixed to the top of the pressure plate 17. A disc spring 19 is fixed to the top of the push rod of the hydraulic cylinder 18, and the top of the disc spring 19 is in contact with the bottom of the crossbeam 8. The disc spring 19 is used to provide deformation compensation for the anchor pile 3 when the hydraulic cylinder 18 stops running, so as to absorb the small deformation of the anchor pile 3 during the stress process and ensure the stability of the anchor pile.

[0037] Reference Figure 1 and Figure 2 A hydraulic pump station 7 is provided on one side of the base 1. The hydraulic pump station 7 is connected to the hydraulic cylinder 18 through an oil pipe and is used to control the operation of the push rod of the hydraulic cylinder 18. In actual operation, the operator can adjust the magnitude and direction of the push force of the hydraulic cylinder 18 by controlling the hydraulic pump station 7, thereby achieving precise adjustment of the stress of the anchor pile 3.

[0038] Reference Figure 3 , Figure 6 , Figure 8 and Figure 9A protective ring 23 is fixed to the top of the pressure plate 17, and the protective ring 23 is fitted onto the outer wall of the hydraulic cylinder 18 to protect the hydraulic cylinder 18. The top of the protective ring 23 has multiple self-locking structures to lock the push rod of the hydraulic cylinder 18 when the hydraulic cylinder 18 stops pushing. The self-locking structure includes a base 25 fixed to the top of the protective ring 23 and a positioning rod 26 that slides through the base 25. The shape of the positioning rod 26 can be customized according to actual needs, such as cylindrical, square, or polygonal, to adapt to different installation environments or enhance structural adaptability. Multiple slots 24 are arranged longitudinally on the outer wall of the push rod of the hydraulic cylinder 18. The positioning rod 26 cooperates with the slots 24 to lock the push rod of the hydraulic cylinder 18. A first fixing plate 28 is fixed to the end of the positioning rod 26 away from the hydraulic cylinder 18, and a tension spring 29 is provided on the side of the first fixing plate 28 that is close to the base 25. Both ends of the tension spring 29 are fixedly connected to the first fixed plate 28 and the base 25 through spring seats, and are used to drive the positioning rod 26 to press tightly against the outer wall of the hydraulic cylinder 18 push rod. The parameter range of the tension spring 29 is: spring stiffness between 50-200N / mm, preload between 100-500N, and the specific values ​​can be adjusted according to actual needs.

[0039] As the push rod of hydraulic cylinder 18 extends, the positioning rod 26 remains in contact with the outer wall of the push rod under the tension of the tension spring 29. Once the positioning rod 26 is aligned with the slot 24, it inserts into the slot 24 under the action of the tension spring 29, thus locking the push rod of hydraulic cylinder 18. This reduces operating losses in the hydraulic pump station 7.

[0040] Reference Figure 8 and Figure 9 The self-locking structure also includes a sliding ring 34 that is slidably sleeved on the outer wall of the protective ring 23. Multiple U-shaped rods 33 are fixed to the top of the sliding ring 34, and a second fixing plate 30 is fixed to the side of the multiple first fixing plates 28 away from the positioning rod 26. Each of the multiple second fixing plates 30 has a groove 31, and a pin 32 is slidably connected within the groove 31, with the pin 32 fixed within the corresponding U-shaped rod 33. In actual operation, when it is necessary to release the self-locking of the hydraulic cylinder 18's push rod, the operator can push the sliding ring 34 downwards. The sliding ring 34 drives the U-shaped rods 33 and the pin 32 to move downwards synchronously. The engagement of the pin 32 with the groove 31 drives the first fixing plate 28 and the positioning rod 26 to move outwards, thereby releasing the insertion engagement between the positioning rod 26 and the slot 24, facilitating the subsequent retraction of the hydraulic cylinder 18's push rod.

[0041] Reference Figures 5-8To further improve the automation level and ease of operation of the equipment, a linkage structure is also provided. This linkage structure is used to simultaneously release the locking of the positioning rod 26 to the hydraulic cylinder 18 push rod when the positioning structure releases the brake between the crossbeam 8 and the frame 2. The linkage structure includes a sliding groove 37 within the crossbeam 8, and a sliding rod 36 (chrome-plated) is slidably connected within the sliding groove 37. The sliding rod 36 is fixedly connected to one of the insert rods 9 near the rotating shaft 10, and is used to drive the sliding rod 36 to move via the insert rod 9. A moving cylinder 35 is slidably connected to the top of the pressure plate 17, and the bottom end of the sliding rod 36 extends slidably into the moving cylinder 35. A push rod 38 is fixed to the side of the moving cylinder 35 near the hydraulic cylinder 18, and a trapezoidal rod 39 is fixed to one side of the sliding ring 34. The push rod 38 and the inclined surface of the trapezoidal rod 39 slide in cooperation, driving the sliding ring 34 to move downwards.

[0042] In actual operation, when the rotating plate 11 and rotating shaft 10 are rotated by the rotating column 16 to release the insertion fit between the insert rod 9 and the pin groove 14, the insert rod 9 disengages from the pin groove 14 and simultaneously pushes the moving cylinder 35 and push rod 38 towards the center via the sliding rod 36. The push rod 38, in cooperation with the trapezoidal rod 39, drives the sliding ring 34 to move downward. The sliding ring 34, through the cooperation of the U-shaped rod 33 (chrome-plated), the pin 32 (chrome-plated), and the inclined groove 31, drives the positioning rod 26 to move outward, thereby releasing the locking of the positioning rod 26 to the hydraulic cylinder 18 push rod. In this way, when the hydraulic cylinder 18 push rod retracts, it can drive the crossbeam 8 to move downward, so as to facilitate the subsequent jacking of the anchor pile 3. The whole process is simple to operate, highly automated, and greatly improves the jacking efficiency.

[0043] Reference Figure 1 and Figure 3 To ensure stable operation of the equipment on uneven ground, multiple hydraulic leveling legs 5 are fixed to the bottom of the base 1. These hydraulic leveling legs 5 are connected to the hydraulic pump station 7 via oil pipes. An inclination sensor 6 is also fixed to the bottom of the base 1 to detect its tilt. In actual operation, the inclination sensor 6 transmits the detected tilt data to the hydraulic pump station 7. Based on this data, the hydraulic pump station 7 adjusts the movement distance of the output end of each hydraulic leveling leg 5, thereby adjusting the levelness of the base 1. This ensures that the hydraulic cylinder 18 can apply a jacking force to the anchor pile 3 in the vertical direction, improving the stability and jacking effect of the equipment.

[0044] Reference Figure 1 and Figure 2To monitor the stress, strain, and temperature of the anchor pile 3 in real time, a fiber optic grating sensor 4 is installed inside the anchor pile 3. The fiber optic grating sensor 4 is connected to an external control center via a wireless transmission module. In actual operation, when the anchor pile 3 is pushed to the ground, the fiber optic grating sensor 4 can monitor the stress, strain, and temperature of the anchor pile 3 in real time and transmit this data to the control center. Based on this data, the control center adjusts the magnitude and direction of the jacking force output by the hydraulic pump station 7, thereby achieving precise adjustment of the stress in the anchor pile 3.

[0045] Reference Figure 1 , Figure 2 and Figure 8 To monitor the internal oil pressure of the hydraulic cylinder 18 in real time during operation, a pressure sensor 22 is installed at the oil port of the hydraulic cylinder 18. The pressure sensor 22 is connected to a corresponding oil pipe to transmit the detected oil pressure data to the hydraulic pump station 7 or the control center. In actual operation, the operator can adjust the magnitude and direction of the oil pressure in the hydraulic cylinder 18 based on the data from the fiber optic grating sensor 4 and the pressure sensor 22 to ensure that the jacking force on the anchor pile 3 is accurate and stable.

[0046] Reference Figure 2 , Figure 8 and Figure 9 The positioning rod 26 has a second inclined surface 27 at its bottom near the hydraulic cylinder 18. The second inclined surface 27 is used to push the positioning rod 26 outwards when the hydraulic cylinder 18 pushes the rod, so that the positioning rod 26 can smoothly align with and insert into the next slot 24. A slide rail 40 is fixed to the top of the pressure plate 17, and the moving cylinder 35 is slidably connected to the slide rail 40. The slide rail 40 allows the moving cylinder 35 to slide smoothly on the pressure plate 17 under the action of the sliding rod 36, improving the stability and reliability of the equipment.

[0047] In another embodiment: Reference Figure 7 The bottom of the crossbeam 8 is provided with a positioning groove 20, and the top of the disc spring 19 fits against the inner wall of the top of the positioning groove 20. The positioning groove 20 is used to limit the disc spring 19 and prevent it from shifting or falling off during the force process. The inner wall of the positioning groove 20 is provided with a first inclined surface 21, which is used to guide the disc spring 19 to extend into the positioning groove 20. In actual operation, when the push rod of the hydraulic cylinder 18 extends, the disc spring 19 is gradually compressed and extended into the positioning groove 20 under the action of the push force. The first inclined surface 21 can guide the disc spring 19 smoothly into the positioning groove 20 and ensure that the disc spring 19 fits tightly against the inner wall of the top of the positioning groove 20, thereby improving the deformation compensation effect of the disc spring 19.

[0048] A method for using an automated stress adjustment device for anchor piles used in basement structural reinforcement includes the following steps:

[0049] S1. When in use, place the base 1 in the designated position and place the anchor pile 3, which has the fiber optic grating sensor 4 installed inside, vertically on the ground to be inserted. Then, move the pressure plate 17 down and place it on top of the anchor pile 3. Then, drive the rotating shaft 10 and the rotating plate 11 to rotate through the rotating column 16 and the crank 15. The rotating plate 11 pulls the insertion rod 9 towards the middle through the connecting rod 13. The insertion rod 9 disengages from the pin groove 14, releasing the clamp between the frame 2 and the crossbeam 8. Control the push rod of the hydraulic cylinder 18 to retract to the corresponding position through the hydraulic pump station 7. Then release the force applied to the crank 15. Under the action of the torsion spring 12, the connecting rod 13 is reinserted into the corresponding pin groove 14.

[0050] S2. Through the cooperation of the hydraulic pump station 7 and multiple hydraulic leveling legs 5, the movement of the push rod of the hydraulic leveling legs 5 can be controlled separately, and the level of the base 1 can be accurately and braked under the detection of the tilt sensor 6, without the need for a technician to supervise the whole process.

[0051] S3. When it is necessary to drive the anchor pile 3, the hydraulic cylinder 18 is extended by controlling the hydraulic pump station 7. Under the action of the crossbeam 8, the hydraulic cylinder 18 applies a reverse thrust to the pressure plate 17 and the anchor pile 3, pushing the anchor pile 3 to the ground. During the pushing process, the fiber optic grating sensor 4 inside the anchor pile 3 monitors the stress, strain, temperature and other parameters of the anchor pile 3 in real time. In addition, a wireless transmission module is added to transmit the monitoring data of the fiber optic grating sensor 4 to the ground control center in real time. The ground control center processes and analyzes the monitoring data in real time, and based on the analysis results and the pressure sensor 22 at this time... The hydraulic cylinder 18 is monitored for oil pressure data. The jacking force of the anchor pile 3 is dynamically adjusted via the hydraulic pump station 7 and the hydraulic cylinder 18 to ensure the anchor pile 3 is always in optimal working condition. The working status of the anchor pile 3 is monitored in real time through the cooperation of the fiber optic grating sensor 4 and the pressure sensor 22, allowing for timely detection of potential safety hazards. Based on the monitoring data, the stress on the anchor pile 3 is intelligently analyzed, and its development trend is predicted. The prestress of the anchor pile 3 is dynamically adjusted to ensure that the bearing capacity and stability of the anchor pile 3 always meet design requirements. This improves the automation level of the equipment and reduces manual intervention and labor intensity.

[0052] S4. In addition, after the hydraulic cylinder 18 extends to a certain distance, in order to ensure that the anchor pile 3 can be continuously and stably inserted into the ground and to reduce the operating loss of the hydraulic pump station 7 when the hydraulic cylinder 18 push rod is stationary, the push rod of the hydraulic cylinder 18 can be locked by mechanical locking. Specifically, when the push rod of the hydraulic cylinder 18 stops, the positioning rod 26 is always in contact with the outer wall of the push rod of the hydraulic cylinder 18 under the tension of the tension spring 29. When the positioning rod 26 is aligned with the slot 24, the positioning rod 26 is inserted into the slot 24 under the action of the tension spring 29, thereby completing the locking of the hydraulic cylinder 18. In addition, the disc spring 19 compensates for the anchor pile 3 and the ground shrinkage and slight deformation.

[0053] S5. When the anchor pile 3 extends to a certain depth and the stroke of the hydraulic cylinder 18 reaches its limit, the hydraulic cylinder 18 stops lifting. At this time, the operator drives the rotating plate 11 and the rotating shaft 10 to rotate by rotating the column 16, releasing the insertion fit between the insert rod 9 and the pin groove 14. When the insert rod 9 disengages from the pin groove 14, the insert rod 9 pushes the moving cylinder 35 and the push rod 38 to move towards the middle through the sliding rod 36. The push rod 38 cooperates with the trapezoidal rod 39 to drive the slot 24 and the U-shaped rod 33 to move down. The U-shaped rod 33 drives the positioning rod 26 to move outward through the cooperation of the pin rod 32 and the inclined groove 31, thereby releasing the locking of the positioning rod 26 to the hydraulic cylinder 18 push rod. When the hydraulic cylinder 18 push rod retracts, it can drive the crossbeam 8 to move down, so that the anchor pile 3 can be pushed again later. The operation is simple and the pushing efficiency is improved.
