Description

Technical Field

[0002] In basement structure reinforcement projects, anchor piles are key supporting components, and their stress state directly affects the safety of the overall structure. In existing technologies, anchor pile jacking equipment mostly uses a fixed hydraulic system, which makes it difficult to dynamically adjust the jacking force according to the real-time stress changes of the pile body, which can easily lead to uneven force on the pile body or excessive energy consumption of the equipment. At the same time, traditional equipment lacks a self-locking mechanism, and the hydraulic system needs to continuously supply pressure to maintain the position of the jacking rod, which not only increases energy consumption, but may also cause safety hazards due to hydraulic fluctuations. In addition, existing equipment requires manual disassembly of positioning components when adjusting the jacking height, which is cumbersome and inefficient.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] In one embodiment: Figure 1 and Figure 2 The invention relates to an adjustment device for a building construction technology field. The device mainly comprises a base 1 and an anchor pile body 3. A frame 2 is welded and fixed to the top of the base 1. A crossbeam 8 and a pressure plate 17 are slidably connected in sequence from top to bottom in 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.

[0020] Reference Figure 4 and Figure 5 A positioning structure is provided between the frame 2 and the crossbeam 8, which is used to release the brake between the crossbeam 8 and the frame 2 when necessary 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, which is used to drive 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 away from each other are rotatably connected to the tops of the two plug rods 9 respectively. A plurality of pin slots 14 are provided on the inner walls of the frame 2 on both sides that are close to each other, and the pin slots 14 are plugged into and matched with the plug rods 9 to position 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 the top of one side of the crank 15 to facilitate driving the rotating shaft 10 and the rotating plate 11 to rotate.

[0021] In actual operation, to adjust the height of beam 8, the operator can rotate crank 15 and shaft 10 via rotating column 16. Shaft 10 rotates rotating plate 11, which, via connecting rod 13, pulls plunger 9 toward the center, disengaging plunger 9 from pin slot 14 and releasing the locking mechanism between frame 2 and beam 8. The operator can then move beam 8 up or down to the desired position. Then, releasing rotating column 16, torsion spring 12 resets rotating plate 11, reinserting plunger 9 into its corresponding pin slot 14, completing the positioning of beam 8.

[0022] 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 body 3 when the hydraulic cylinder 18 stops operating, so as to absorb the slight deformation of the anchor pile body 3 during the force application process and ensure the stability of the anchor pile body.

[0023] 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 via an oil pipe and is used to control the operation of the hydraulic cylinder 18's push rod. In actual operation, the operator can adjust the magnitude and direction of the hydraulic cylinder 18's push force by controlling the hydraulic pump station 7, thereby achieving precise adjustment of the stress of the anchor pile body 3.

[0024] Reference Figure 3 、 Figure 6 、 Figure 8 and Figure 9A protective ring 23 is also fixed to the top of the pressure plate 17, and the protective ring 23 is mounted on the outer wall of the hydraulic cylinder 18 to protect the hydraulic cylinder 18. The top of the protective ring 23 is provided with multiple sets of self-locking structures, which are used 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 set according to actual needs, such as cylindrical, square or polygonal, to adapt to different installation environments or enhance structural adaptability. The outer wall of the push rod of the hydraulic cylinder 18 has multiple slots 24 arranged longitudinally. 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 where the first fixing plate 28 and the base 25 are close to each other. Both ends of the tension spring 29 are fixedly connected to the first fixed plate 28 and the base 25 via spring seats, driving the positioning rod 26 to closely contact the outer wall of the push rod of the hydraulic cylinder 18. The parameters of the tension spring 29 range from 50 to 200 N / mm in spring stiffness and 100 to 500 N in preload force. The specific values ​​can be adjusted according to actual needs.

[0025] When the push rod of hydraulic cylinder 18 extends, positioning rod 26, under the tension of tension spring 29, always abuts against the outer wall of the push rod of hydraulic cylinder 18. When positioning rod 26 is aligned with retaining groove 24, positioning rod 26 is inserted into retaining groove 24 under the action of tension spring 29, completing the locking of the push rod of hydraulic cylinder 18. This reduces operating losses of hydraulic pump station 7.

[0026] 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. A plurality of 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 plurality of first fixing plates 28 away from the positioning rod 26. An inclined groove 31 is provided in each of the plurality of second fixing plates 30, and a pin rod 32 is slidably connected in the inclined groove 31, and the pin rod 32 is fixed in the corresponding U-shaped rod 33. In actual operation, when it is necessary to release the self-locking of the push rod of the hydraulic cylinder 18, the operator can push the sliding ring 34 downward. The sliding ring 34 drives the U-shaped rod 33 and the pin rod 32 to move downward synchronously, and the cooperation of the pin rod 32 and the inclined groove 31 can drive the first fixing plate 28 and the positioning rod 26 to move outward, thereby releasing the plug-in fit between the positioning rod 26 and the card slot 24, which is convenient for the later retraction of the push rod of the hydraulic cylinder 18.

[0027] Reference Figure 5-Figure 8In order to further improve the degree of automation and ease of operation of the equipment, a linkage structure is also provided. The linkage structure is used to synchronously release the lock of the positioning rod 26 on the push rod of the hydraulic cylinder 18 when the positioning structure releases the brake between the crossbeam 8 and the frame 2. The linkage structure includes a sliding groove 37 provided in the crossbeam 8, and a sliding rod 36 (chrome-plated) is slidably connected in the sliding groove 37. The sliding rod 36 is fixedly connected to one side of one of the insertion rods 9 close to the rotating shaft 10, and is used to drive the sliding rod 36 to move through the insertion rod 9. The top of the pressure plate 17 is slidably connected to the moving cylinder 35, and the bottom end of the sliding rod 36 slides and extends into the moving cylinder 35. A push rod 38 is fixed to the side of the moving cylinder 35 close to the hydraulic cylinder 18, and a trapezoidal rod 39 is fixed to one side of the sliding ring 34. The push rod 38 slides with the inclined surface of the trapezoidal rod 39 to drive the sliding ring 34 to move downward.

[0028] In actual operation, when the rotating column 16 drives the rotating plate 11 and the rotating shaft 10 to rotate, releasing the insertion rod 9 from the pin slot 14, the insertion rod 9 simultaneously disengages from the pin slot 14, pushing the movable cylinder 35 and the push rod 38 toward the center via the sliding rod 36. The push rod 38 cooperates with the trapezoidal rod 39 to drive the sliding ring 34 downward. The sliding ring 34, through the cooperation of the U-shaped rod 33 (chrome-plated), the pin 32 (chrome-plated), and the inclined slot 31, drives the positioning rod 26 outward, thereby releasing the locking force of the positioning rod 26 on the hydraulic cylinder 18's push rod. This allows the crossbeam 8 to move downward when the hydraulic cylinder 18's push rod retracts, facilitating subsequent pushing of the anchor pile 3. The entire process is simple to operate and highly automated, significantly improving pushing efficiency.

[0029] Reference Figure 1 and Figure 3 In order to ensure that the equipment can operate stably on uneven ground, multiple hydraulic leveling legs 5 are fixed to the bottom of the base 1. The multiple hydraulic leveling legs 5 are connected to the hydraulic pump station 7 through oil pipes. A tilt sensor 6 is also fixed to the bottom of the base 1 to detect the inclination of the base 1. In actual operation, the tilt sensor 6 transmits the detected inclination data to the hydraulic pump station 7. The hydraulic pump station 7 adjusts the moving distance of the output end of each hydraulic leveling leg 5 based on this data, thereby adjusting the horizontality of the base 1. This ensures that the hydraulic cylinder 18 can apply a jacking force to the anchor pile body 3 in the vertical direction, thereby improving the stability and jacking effect of the equipment.

[0030] Reference Figure 1 and Figure 2To monitor the stress, strain, and temperature of the anchor pile 3 in real time, a fiber grating sensor 4 is installed inside the anchor pile 3. This sensor is connected to an external control center via a wireless transmission module. In actual operation, as the anchor pile 3 is pushed into the ground, the fiber grating sensor 4 monitors the stress, strain, and temperature of the anchor pile 3 in real time and transmits this data to the control center. Based on this data, the control center adjusts the magnitude and direction of the thrust output by the hydraulic pump station 7, thereby precisely adjusting the stress of the anchor pile 3.

[0031] Reference Figure 1 、 Figure 2 and Figure 8 To monitor the oil pressure within hydraulic cylinder 18 in real time during operation, a pressure sensor 22 is installed at the oil port of hydraulic cylinder 18. Pressure sensor 22 is connected to the corresponding oil pipe and transmits 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 within hydraulic cylinder 18 based on the data from fiber grating sensor 4 and pressure sensor 22 to ensure accurate and stable thrust force on the anchor pile body 3.

[0032] Reference Figure 2 、 Figure 8 and Figure 9 A second inclined surface 27 is provided at the bottom of the positioning rod 26 near the hydraulic cylinder 18. This second inclined surface 27 is used to push the positioning rod 26 outward when the push rod of the hydraulic cylinder 18 extends, allowing the positioning rod 26 to 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 movable cylinder 35 is slidably connected to the slide rail 40. The slide rail 40 ensures that the movable cylinder 35 slides smoothly on the pressure plate 17 under the action of the sliding rod 36, thereby improving the stability and reliability of the equipment.

[0033] In another embodiment: Figure 7 , a positioning groove 20 is provided at the bottom of the crossbeam 8, and the top of the disc spring 19 fits against the top inner wall of the positioning groove 20. The positioning groove 20 is used to limit the disc spring 19 to prevent the disc spring 19 from shifting or falling off during the force application process. The inner wall of the positioning groove 20 is provided with a first inclined surface 21, and the first inclined surface 21 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 is extended, the disc spring 19 is gradually compressed and extended into the positioning groove 20 under the action of the pushing force. The first inclined surface 21 can guide the disc spring 19 to enter the positioning groove 20 smoothly, and ensure that the disc spring 19 fits tightly against the top inner wall of the positioning groove 20, thereby improving the deformation compensation effect of the disc spring 19.

[0034] A method for using an automatic stress adjustment device for anchor piles used for basement structure reinforcement comprises the following steps: S1. When in use, place the base 1 at the designated position, and place the anchor pile body 3 with the fiber Bragg grating sensor 4 installed inside vertically on the ground to be inserted, then move the pressure plate 17 downward and place it on the top of the anchor pile body 3, then drive the rotating shaft 10 and the rotating plate 11 to rotate through the rotating column 16 and the crank 15, and the rotating plate 11 pulls the insertion rod 9 to the middle through the connecting rod 13, and the insertion rod 9 is disengaged from the pin groove 14, releasing the clamping of the frame 2 and the crossbeam 8, and the hydraulic pump station 7 controls the push rod of the hydraulic cylinder 18 to retract to the corresponding position, then release the force applied to the crank 15, and the connecting rod 13 is reinserted into the corresponding pin groove 14 under the action of the torsion spring 12; S2. The hydraulic pump station 7 cooperates with the multiple hydraulic leveling legs 5 to control the movement of the push rods of the hydraulic leveling legs 5 respectively, and can accurately and brake the horizontality of the base 1 under the detection of the inclination sensor 6, without the need for technician supervision throughout the process; S3. When the anchor pile body 3 needs to be pressed, the hydraulic pump station 7 controls the extension of the push rod of the hydraulic cylinder 18. Under the action of the crossbeam 8, the hydraulic cylinder 18 applies a reverse thrust to the pressure plate 17 and the anchor pile body 3, pushing the anchor pile body 3 to the ground. During the pushing process, the fiber optic Bragg grating sensor 4 in the anchor pile body 3 monitors the stress, strain, temperature and other parameters of the anchor pile body 3 in real time. In addition, a wireless transmission module is added to transmit the monitoring data of the fiber optic Bragg 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 according to the analysis results and the pressure sensor 22 at this time, The oil pressure data in the hydraulic cylinder 18 is detected, and the jacking force of the anchor pile body 3 is dynamically adjusted through the hydraulic pump station 7 and the hydraulic cylinder 18 to ensure that the anchor pile body 3 is always in the best working condition; the working condition of the anchor pile body 3 is monitored in real time through the cooperation of the fiber grating sensor 4 and the pressure sensor 22, and potential safety hazards are discovered in time; based on the monitoring data, the stress condition of the anchor pile body 3 is intelligently analyzed and its development trend is predicted; the prestress of the anchor pile body 3 is dynamically adjusted to ensure that the bearing capacity and stability of the anchor pile body 3 always meet the design requirements; the degree of automation of the equipment is improved, and manual intervention and labor intensity are reduced; S4. In addition, when the hydraulic cylinder 18 is extended to a certain distance, in order to ensure that the anchor pile body 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 at rest, the hydraulic cylinder 18 push rod can be locked by mechanical locking. Specifically, when the hydraulic cylinder 18 push rod stops, the positioning rod 26 always abuts against the outer wall of the hydraulic cylinder 18 push rod 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 micro-deformation of the anchor pile body 3 and the ground contraction. S5. When the anchor pile body 3 extends to a certain depth and the stroke of the hydraulic cylinder 18 has reached its limit, the hydraulic cylinder 18 stops lifting. At this time, the staff drives the rotating plate 11 and the rotating shaft 10 to rotate by the rotating column 16, releasing the plug-in fit between the insertion rod 9 and the pin groove 14. When the insertion rod 9 disengages from the pin groove 14, the insertion rod 9 pushes the moving cylinder 35 and the push rod 38 to move toward the middle through the sliding rod 36. The push rod 38 cooperates with the trapezoidal rod 39 to drive the card groove 24 and the U-shaped rod 33 to move downward. 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 on the hydraulic cylinder 18 pushing rod. When the hydraulic cylinder 18 pushing rod contracts, it can drive the crossbeam 8 to move downward, so as to facilitate the anchor pile body 3 to be pushed later. The operation is simple and the pushing efficiency is improved.
