Abstract
Description
Technical Field
[0001] This utility model relates to the field of pile foundation positioning technology, and more specifically, it relates to a pile foundation positioning and anti-deviation device for pile foundation engineering. Background Technology
[0002] In modern construction engineering, pile foundation positioning is a crucial preliminary task. Typically, at least four or more positioning points are identified on the construction site. These points are marked by foundation piles to provide precise guidance for subsequent construction processes. These foundation piles used for positioning are called positioning piles, and their accuracy directly affects the quality and safety of the entire construction project.
[0003] With the rapid development of the construction industry, the requirements for pile foundations have become increasingly stringent. However, existing pile positioning methods have some serious defects. The most common practice is to drive the piles directly into the ground, but this method has many problems in actual operation. First, the piles are prone to displacement during the driving process. Second, even if the piles are successfully driven in, subsequent external forces may cause small but critical displacements in the pile position. Although these displacements seem small, they may be amplified in the entire building structure, ultimately leading to serious safety hazards and quality problems.
[0004] Another prominent problem is that existing positioning devices are difficult to adapt to complex terrain conditions. The ground at construction sites is often uneven, and traditional positioning devices lack effective adjustment mechanisms to cope with this situation. This results in the positioning device not being able to fully fit the ground, and there may be situations where it is suspended or has poor contact at certain points. When the pile foundation is driven in later, these unstable contact points may cause the pile foundation to shift. This shift not only affects the overall stability of the building, but also increases the safety risks after completion, posing a potential threat to future residents.
[0005] In addition, existing pile foundation positioning and anti-deviation devices also have operational problems during use. They usually require surveyors to manually adjust multiple support devices. This manual operation introduces a lot of subjective factors. Differences in the experience, skills and judgment standards of different operators may lead to inconsistent adjustment results. This subjectivity may cause some points of the support device to have poor contact with the ground, or overall imbalance. More seriously, this manual adjustment makes it difficult to ensure that the support device is absolutely perpendicular to the ground, and the deviation in perpendicularity will directly affect the positioning accuracy of the pile foundation.

[0017] (III) Beneficial Effects
[0018] Compared with the prior art, this utility model provides a pile foundation positioning and anti-deviation device for pile foundation engineering, which has the following beneficial effects:
[0019] 1. The pile foundation positioning and anti-deviation device used in this pile foundation project achieves precise guidance during pile installation by setting a positioning device on the outside of the pile and adopting a combination structure of base plate and base. The design of guide wheel on the inside of the base and guide groove on the outside of the pile is coordinated to ensure the stability of the pile during insertion and effectively prevent the pile from deviating during installation, which greatly improves the accuracy of pile positioning. The rolling cooperation between the guide wheel and the guide groove significantly reduces the frictional resistance when the pile is inserted, making the installation process smoother and improving construction efficiency.
[0020] 2. The support device adopts a combination structure of support rods, threaded sleeves and support sleeves, etc. Precise adjustment is achieved through threaded connection. The top plate at the top of the support rod and the hemispherical top block at the bottom ensure good contact with the ground and uniform force distribution. The fixing block inside the support sleeve is connected to the limiting sleeve through the connecting rod, which enhances the overall structural strength. This multi-point support design can effectively adapt to different terrain conditions and ensure the stability and verticality of the device.
[0021] 3. The adapter mechanism, through the precise cooperation of the slot, driven wheel, driving wheel, limit sleeve, push spring, locking block, and storage slot, along with the top mounting bracket and the power system of the motor and reducer, achieves automatic adjustment of the support structure. This avoids the subjectivity of traditional manual adjustment, improves adjustment accuracy and efficiency, and forms an adaptive system. The meshing transmission between the driving wheel and the driven wheel, combined with the drive of the motor and reducer, realizes the adjustment of the support structure. The rounded corner design of the slot and locking block, combined with the elastic support of the push spring, allows the system to adaptively adjust according to the ground conditions. When a support point contacts the ground, the mechanism design of the locking block sliding out of the slot avoids excessive pressure and ensures the balance of multi-point support. This adaptive mechanism not only improves the flexibility of the device but also ensures the stability and reliability of the support, effectively solving the problem that traditional positioning devices are difficult to adapt to complex terrain.

[0032] Please see Figures 1-6A pile foundation positioning and anti-deviation device for pile foundation engineering includes a pile 1. A positioning device is provided on the outside of the pile 1. The positioning device includes a base plate 2 and a base 3. The base 3 is located on the outside of the pile 1. The base plate 2 is fixedly located at the bottom end of the base 3. A support device is installed on the base plate 2. The support device includes a support rod 4, a threaded sleeve 5, and a support sleeve 6. The outer wall of the support rod 4 is movably connected to the threaded sleeve 5 by threads. Multiple threaded sleeves 5 are rotatably installed on the top of the support sleeve 6. Multiple support sleeves 6 are detachably installed on the base plate 2. An adapter mechanism is provided on the support sleeve 6. The adapter mechanism includes a slot 7 and a... The support rod 4 has a drive wheel 8, a drive wheel 9, a limiting sleeve 10, a push spring 11, a locking block 12, and a storage groove 13. Multiple locking grooves 7 are opened on the outside of the support rod 4. The driven wheel 8 is fixedly connected to the outside of the screw sleeve 5. The drive wheel 9 is rotatably installed on the top of the support sleeve 6 and meshes with multiple driven wheels 8. The limiting sleeve 10 is fixedly installed on the inside of the support sleeve 6. Multiple storage grooves 13 are opened on the inside of the limiting sleeve 10. The push spring 11 is movably installed in the storage groove 13. The locking block 12 is connected to one end of the push spring 11 and slides in the storage groove 13. One end of the locking block 12 is engaged in the locking groove 7.
[0033] Multiple guide wheels 14 are movably provided on the inner side of the base 3, and guide grooves 15 are correspondingly provided on the outer side of the pile 1, with the guide wheels 14 movably positioned in the guide grooves 15.
[0034] In this embodiment, when the device is used for pile foundation positioning, the base 3 and base plate 2 are first leveled and fixed on the ground. Then, the pile 1 is gradually inserted into the inner side of the base 3, and the multiple guide grooves 15 on the outer side of the pile 1 correspond to the positions of the guide wheels 14. Then, the pile 1 is slid into the inner side of the base 3, and the guide wheels 14 roll along the guide grooves 15, making the movement of the pile 1 smoother. Then, the top of the pile 1 is hammered by an external hydraulic hammer, so that the conical block at the bottom of the pile 1 is gradually inserted into the soil. Finally, the pile 1 is gradually hammered into the ground.
[0035] Please see Figures 1-6 As a further implementation of the overall equipment: a top plate 16 is fixedly provided at the top of the support rod 4.
[0036] The bottom end of the support rod 4 is fixed with a top block 17, which is a hemispherical structure design.
[0037] A fixing block 18 is fixedly provided inside the support sleeve 6, and a connecting rod 19 is fixedly provided on the outside of the fixing block 18. The fixing block 18 is fixedly connected to the limiting sleeve 10 through the connecting rod 19.
[0038] The top of the support sleeve 6 is fixedly provided with a mounting bracket 20, and the top of the mounting bracket 20 is provided with a motor 21.
[0039] The top of the mounting bracket 20 is detachably equipped with a reducer 22. The output end of the reducer 22 passes through the mounting bracket 20 and is connected to the drive wheel 9. The input end of the reducer 22 is connected to the output end of the motor 21.
[0040] Both the inner wall of the card slot 7 and the outer wall of the card block 12 adopt a rounded corner structure design.
[0041] More specifically, when it is necessary to stably and vertically install the base 3 and the base plate 2 on the ground, first place the base 3 and the base plate 2 on the ground, then horizontally install an external level on the base plate 2, and then adjust the base 3 and the base plate 2, observing with the level to ensure that the base 3 and the base plate 2 are perpendicular to the ground. Then, use external force to simply limit the position of the base 3 and the base plate 2, and then simultaneously turn on all the motors 21. After the output end of the motor 21 is reduced by the reducer 22 connected to the output end, it drives the drive wheel 9 set on the inner side of the mounting bracket 20 to rotate. Then the drive wheel 9 will drive all the driven wheels 8 to rotate respectively. Then, the driven wheel 8 will drive the threaded sleeve 5 to rotate synchronously on the support sleeve 6. Since the outer side of the support rod 4 is movably connected to the inner wall of the threaded sleeve 5 through the thread, and the locking block 12 set on the inner side of the limiting sleeve 10 and the locking groove 7 opened on the outer side of the support rod 4 cooperate to limit the support rod 4, so that the support rod 4 will not rotate. Then the support rod 4 will slide along the threaded sleeve 5 and the support rod 4, and the support rod 4 will drive the locking groove 7 opened on the outer side to slide, so that the locking block 12 will slide relative to the locking groove 7. Then the top block 17 set at the bottom of the support rod 4 will gradually contact the ground one by one. When part of the top block 17 set at the bottom of the support rod 4 contacts the ground... Upon contact, due to the limitation imposed by the peripheral device on the base 3 and the base plate 2, and the inability of the support rod 4 to continue sliding along the limiting sleeve 10 and the threaded sleeve 5, and at this time the motor 21 still drives the drive wheel 9 to rotate through the reducer 22, thereby causing the driven wheel 8 to continue driving the threaded sleeve 5 to rotate. Since the support rod 4 can no longer slide, the threaded sleeve 5 will apply a rotational force to the support rod 4, and then the inner wall of the slot 7 will press against the outer wall of the block 12. Due to the rounded corners of the inner wall and edges of the slot 7, and the rounded corner design of the outer wall of the block 12, the block 12 will gradually slide out of the slot 7 and into the storage slot 13. At the same time, the block 12 will press against the storage slot 13. The push spring 11 in the groove 13 compresses the support rod 4, causing it to rotate with the screw sleeve 5. This prevents the support rod 4 from continuing to lower the top block 17. Once the top blocks 17 at the bottom of all the support rods 4 are in contact with the ground, the motor 21 is turned off. Then, the base 3 and the base plate 2 are directly fixed to the ground using external fixing devices. This allows the device to achieve surface support through the cooperation of multiple support rods 4, flexibly adapting to various ground surfaces and improving the device's flexibility and stability. The fixing block 18 and connecting rod 19 further strengthen the internal structural strength of the support sleeve 6, ensuring stable use of the device.
[0042] In summary, when using or operating the equipment: First, level and fix the base 3 and base plate 2 on the ground. Then, gradually insert the pile 1 into the inside of the base 3, so that the multiple guide grooves 15 on the outside of the pile 1 correspond to the positions of the guide wheels 14. Then, slide the pile 1 into the inside of the base 3, and let the guide wheels 14 roll along the guide grooves 15 to make the movement of the pile 1 smoother. Then, use the external hydraulic hammer to strike the top of the pile 1, so that the conical block set at the bottom of the pile 1 is gradually inserted into the soil. Finally, hammer the pile 1 into the ground.
[0043] When it is necessary to stably and vertically install the base 3 and the base plate 2 on the ground, first place the base 3 and the base plate 2 on the ground, then horizontally install an external level on the base plate 2, and then adjust the base 3 and the base plate 2, observing with the level to ensure that the base 3 and the base plate 2 are perpendicular to the ground. Then, use external force to simply limit the base 3 and the base plate 2, and then simultaneously turn on all motors 21. After the output end of the motor 21 is reduced by the reducer 22 connected to the output end, it drives the drive wheel 9 set on the inner side of the mounting bracket 20 to rotate. Then the drive wheel 9 will drive all the driven wheels 8 to rotate respectively. The driving wheel 8 drives the threaded sleeve 5 to rotate synchronously on the support sleeve 6. Since the outer side of the support rod 4 is movably connected to the inner wall of the threaded sleeve 5 via threads, and the locking block 12 on the inner side of the limiting sleeve 10 and the locking groove 7 on the outer side of the support rod 4 cooperate to limit the support rod 4, preventing it from rotating. Then, the support rod 4 slides along the threaded sleeve 5 and the support rod 4, and the support rod 4 drives the locking groove 7 on the outer side to slide, causing the locking block 12 to slide relative to the ground within the groove 7. Then, the top blocks 17 at the bottom of the support rod 4 gradually contact the ground. When some of the top blocks 17 at the bottom of the support rod 4 contact the ground... Due to the limitation imposed by the peripheral device on the base 3 and the base plate 2, and because the support rod 4 cannot continue to slide along the limiting sleeve 10 and the screw sleeve 5, and at this time the motor 21 still drives the drive wheel 9 to rotate through the reducer 22, thereby causing the driven wheel 8 to continue to drive the screw sleeve 5 to rotate. Since the support rod 4 cannot continue to slide, the screw sleeve 5 will apply a rotational force to the support rod 4. Then the inner wall of the slot 7 will press against the outer wall of the block 12. Due to the rounded corners of the inner wall and edges of the slot 7, and the rounded corner design of the outer wall of the block 12, the block 12 will gradually slide out of the slot 7 and into the storage slot 13. At the same time, the block 12 will press against the storage slot. The push spring 11 in section 13 compresses the support rod 4, causing it to rotate with the screw sleeve 5. This prevents the support rod 4 from continuing to lower the top block 17. Once the top blocks 17 at the bottom of all the support rods 4 are in contact with the ground, the motor 21 is turned off. Then, the base 3 and the base plate 2 are directly fixed to the ground using external fixing devices. This allows the device to achieve surface support through the cooperation of multiple support rods 4, flexibly adapting to various ground surfaces and improving the device's flexibility and stability. The fixing block 18 and connecting rod 19 further strengthen the internal structural strength of the support sleeve 6, ensuring stable use of the device.
