Description

Technical Field

[0001] This invention relates to the field of pile foundation positioning technology, specifically to a pile foundation positioning and anti-deviation structure for pile foundation engineering. Background Technology

[0002] Pile foundation positioning is one of the core procedures in building pile foundation construction, which determines the overall quality of pile foundation construction. It is widely used in various infrastructure scenarios such as housing construction, bridge engineering, and rail transit. The pile foundation column needs to be accurately and vertically inserted into the ground. Its positioning verticality and accuracy affect the stability and bearing capacity of the subsequent building structure. Therefore, the vertical stability of the guide structure and the adaptability of the positioning structure are crucial in the pile foundation positioning process.

[0003] Existing pile foundation positioning devices are prone to tilting when the ground is uneven, as the guiding and positioning structure is easily affected by the ground slope, thus affecting the verticality of the pile foundation and causing deviation during pile positioning. Furthermore, to prevent this deviation from affecting positioning accuracy, the guiding mechanism needs repeated adjustments until it is perpendicular to the ground. This adjustment process is time-consuming and not conducive to adaptive adjustments based on ground inclination, reducing the positioning accuracy of pile foundation construction. In addition, existing pile foundation positioning devices are typically placed at the location where the pile needs to be driven in, using their own weight to provide stable guidance for the subsequent pile penetration. When the pile penetrates the ground, external force is required for guidance, which can easily act on the positioning device itself, causing it to shift in place and affecting the vertical angle of the pile after penetration.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0005] The purpose of this invention is to provide a pile foundation positioning and anti-deviation structure for pile foundation engineering to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pile foundation positioning and anti-deviation structure for pile foundation engineering, comprising a base, with mounting columns symmetrically connected through the four corners of the base, a support seat connected through a fixed seat above the mounting columns, a protruding position on the outer side of the mounting columns fixed to the fixed seat, a support seat installed above the fixed seat, a platform installed above the support seat, a movable sleeve installed at the central opening of the cavity inside the platform, a guide tube installed inside the movable sleeve, bidirectional threaded rods symmetrically rotatably installed inside the cavity of the platform, a fixed plate threadedly slidingly connected to the left and right sides of the two bidirectional threaded rods, the right ends of the two bidirectional threaded rods connected to the fixed seat through a motor gear set, racks connected to the front side of the right fixed plate and the rear side of the left fixed plate, toothed rings symmetrically meshing on the outer sides of the two racks, a bevel gear fixedly installed at the lower end of the inner shaft of the toothed ring, an oil adjustment assembly between the four bevel gears and the guide tube, and a fixing assembly between the bevel gears and the mounting columns.

[0007] Optionally, the movable sleeve is designed as a spherical structure, the central opening of the platform corresponds to the spherical shape of the movable sleeve, the central opening of the platform is used for the movable sleeve to move circumferentially within the platform, and the lower section of the guide tube is designed to be longer and heavier at the lower part of the movable sleeve.

[0008] Optionally, the oil adjustment assembly includes four sliders. The upper ends of the four sliders are rotatably connected to bevel gears via bearings. Sloping groove plates are slidably connected to the front and rear sides of the sliders via protruding columns. The sloping groove plates are installed in the vertical grooves on the inner wall of the support seat notch. Sliding groove plates are slidably installed at the lower ends of the four sliders. A plug body is connected to the bottom of the sliding groove plate. An oil tank is slidably connected to the lower end of the plug body via a spring seal. The oil tank is installed on the upper end of the fixed seat. The inner cavities of the four oil tanks are connected to four oil tanks (secondary) via hoses and electric control valves. The four oil tanks (secondary) are fitted and fixedly installed in the inner opening at the top of the guide tube. A plug body (secondary) is slidably installed in the inner cavity of the oil tank (secondary) via a spring seal. A contact block is fixed to the inward output end of each of the four plug bodies (secondary).

[0009] Optionally, the rack teeth are installed at an angle, and the angle of the rack corresponds to the angle of the bevel gear. The angle of the opening on the inclined slot plate also corresponds to the angle of the bevel gear.

[0010] Optionally, the oil tanks are distributed at equal angles around the inside of the top of the guide tube, and the inner cross-section of the contact block is wider at the top and narrower at the bottom. The contact block is used for positioning according to the diameter of the pile column.

[0011] Optionally, the fixing component includes a transmission gear, the outer side of which meshes with a bevel gear, and a threaded sleeve is fixedly connected to the transmission gear via an inner shaft. The threaded sleeve is rotatably mounted in the upper cavity of the mounting column via a bearing. A sliding column is threadedly connected to the inner side of the threaded sleeve via a helical groove. The sliding column is vertically limited and slidably mounted in the middle opening of the mounting column. A threaded groove column is rotatably connected to the lower end of the sliding column via a bearing. The threaded groove column is threadedly connected to the lower cavity of the mounting column.

[0012] Optionally, the upper section of the sliding column is provided with a partial helical protrusion on its outer wall. The helical protrusion is used for the sliding column to rotate and move within the inner cavity of the threaded sleeve. The lower section of the mounting column is provided with a protrusion on its inner wall. The protrusion is used for the threaded column to rotate and move within the mounting column.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention, through the cooperation between a platform, a spherical movable sleeve, and a guide tube, allows the movable sleeve to adaptively adjust its circumferential angle within the platform's opening using its spherical structure. The lower section of the guide tube is designed to be longer and heavier than the upper section of the guide tube in the movable sleeve. Under the influence of gravity, in conjunction with the circumferential movement of the spherical movable sleeve, the guide tube remains perpendicular to the ground, enabling rapid adaptive adjustments even on uneven ground. Simultaneously, the bidirectional threaded rod's positive and negative threads on both sides drive the fixing plates on both sides to move synchronously towards the center until they clamp and fix the movable sleeve from both sides. This positions and fixes the adjusted spherical movable sleeve and guide tube, effectively preventing the guide tube from shifting and affecting the vertical positioning of the pile foundation column. This achieves anti-deviation positioning of the pile foundation, improving its verticality and accuracy. This invention, through the arrangement of an oil adjustment component and a fixing component, allows the contact block to push the oil in the second oil tank when the diameter of the pile foundation column is large. The oil then enters the first oil tank through a hose, pushing the plug body to move. This, in turn, drives the sliding plate, slider, and bevel gear to move in coordination. As the bevel gear moves along the inclined surface of the rack, the meshing position between the bevel gear and the transmission gear gradually changes from a smaller diameter to a larger diameter. This change in diameter meshing drives the transmission gear to rotate, allowing the rotational speed of the transmission gear to be adaptively adjusted according to the diameter of the pile foundation column. Through the cooperation of the oil adjustment component and the fixing component, the underground drilling depth of the screw groove column can be adjusted synchronously with the adjustment of the rotational speed of the transmission gear. When the diameter of the pile foundation column is large, the drilling depth of the screw groove column is deeper, further improving the positioning accuracy of the pile foundation column in the guide tube.

[0016] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention. Example 1

[0017] Please see Figures 1 to 11This invention provides a technical solution: a pile foundation positioning and anti-deviation structure for pile foundation engineering, including a base 1, with mounting columns 2 symmetrically connected to the four corners of the base 1. A support seat 4 is connected to a fixing seat 3 above the mounting columns 2. The outer protrusion of the mounting column 2 is fixed to the fixing seat 3. The support seat 4 is installed above the fixing seat 3, and a platform 5 is installed above the support seat 4. A movable sleeve 6 is installed at the central opening of the internal cavity of the platform 5. A guide tube 7 is installed inside the movable sleeve 6. The movable sleeve 6 is designed as a spherical structure, and the central opening of the platform 5 corresponds to the spherical shape of the movable sleeve 6. The central opening of the platform 5 is used for the movable sleeve 6 to... The guide tube 7, with its inner circumferential movement, is designed to be longer and heavier at the lower part of the movable sleeve 6. A double-threaded rod 8 is symmetrically and rotatably installed within the cavity of the platform 5. Fixed plates 9 are threadedly and slidably connected to the two double-threaded rods 8 on both the left and right sides. The right ends of the two double-threaded rods 8 are connected to the fixed seat 3 via a motor gear set. Racks 10 are connected to the front of the right fixed plate 9 and the rear of the left fixed plate 9. Gear rings 11 are symmetrically meshed on the outer sides of the two racks 10. A bevel gear 12 is fixedly installed at the lower end of the inner shaft of the gear ring 11. An oil regulating component is provided between the four bevel gears 12 and the guide tube 7. The liquid regulating assembly includes four sliders 131. The upper ends of the four sliders 131 are rotatably connected to bevel gears 12 via bearings. Sloping plates 132 are slidably connected to the front and rear sides of the sliders 131 via protrusions. The sloping plates 132 are installed in the vertical grooves on the inner wall of the notch of the support base 4. The toothed teeth of the rack 10 are installed at an angle, and the angle of the rack 10 corresponds to the angle of the bevel gear 12. The angle of the opening on the sloping plate 132 corresponds to the angle of the bevel gear 12. Sliding plates 133 are slidably installed at the lower ends of the four sliders 131. A plug 134 is connected to the bottom of the sliding plate 133. The lower end of the plug 134 is connected to... The spring-sealed sliding connection is connected to the first oil tank 135, which is installed on the upper end of the fixed base 3. The inner cavity of each of the four first oil tanks 135 is connected to the second oil tank 136 through hoses and electric control valves. The four second oil tanks 136 are fitted and fixedly installed in the inner opening at the top of the guide tube 7. The inner cavity of the second oil tank 136 is slidably installed with the second plug 137 through the spring seal. The inward output end of each of the four second plugs 137 is fixed with a stop block 138. The second oil tanks 136 are circumferentially and angularly distributed inside the top of the guide tube 7. The inner cross section of the stop block 138 is a structure that is wider at the top and narrower at the bottom. The stop block 138 is used for positioning according to the diameter of the pile column.

[0018] The base 1 is installed at the preset position of the pile foundation. Due to the unevenness of the ground, the spherical movable sleeve 6 self-adaptively adjusts circumferentially within the opening of the platform 5. Because the lower section of the guide tube 7 is longer and heavier than the upper section, under the combined effect of gravity and the circumferential movement of the spherical movable sleeve 6, the guide tube 7 always remains perpendicular to the ground, avoiding deviation that would affect the vertical positioning of the pile foundation column, thus achieving positioning and preventing deviation. After the guide tube 7 is vertically stable, the motor drives the gear set to rotate the two sets of bidirectional threaded rods 8. With the help of the positive and negative threads on the left and right sides, the two fixing plates 9 move synchronously towards the middle, contacting and clamping the spherical movable sleeve 6 and fixing it. Then, the pile foundation column is moved from the guide tube. 7. The upper end is vertically inserted. During its sinking process, it pushes open the four sets of abutment blocks 138, pushes the second plug body 137 to squeeze the oil in the second oil tank 136, and the oil enters the first oil tank 135 through the hose and pushes the first plug body 134 to move, thereby adjusting the position of the slide plate 133. The slider 131 and the bevel gear 12 slide with the slide plate 133 and are adjusted along the inclined plate 132, so that when the bevel gear 12 moves along the inclined surface of the rack 10, the meshing position with the transmission gear 141 gradually changes from a smaller diameter to a larger diameter, driving the transmission gear 141 to rotate, so that the speed of the transmission gear 141 can be adaptively adjusted with the diameter of the pile column. Example 2

[0019] Based on Example 1, please refer to Figures 1 to 11 A fixing assembly is provided between the bevel gear 12 and the mounting post 2. The fixing assembly includes a transmission gear 141, which meshes with the bevel gear 12 on its outer side. The transmission gear 141 is fixedly connected to a threaded sleeve 142 via an inner shaft. The threaded sleeve 142 is rotatably mounted in the upper cavity of the mounting post 2 via a bearing. A sliding post 143 is threadedly connected to the inner side of the threaded sleeve 142 via a spiral groove. The sliding post 143 is vertically limited and slidably mounted in the middle opening of the mounting post 2. A threaded post 144 is rotatably connected to the lower end of the sliding post 143 via a bearing. The threaded post 144 is threadedly connected to the lower cavity of the mounting post 2. A partial spiral protrusion is provided on the outer wall of the upper section of the sliding post 143. The spiral protrusion is used for the sliding post 143 to rotate and move within the cavity of the threaded sleeve 142. A protrusion is provided on the inner wall of the lower cavity of the mounting post 2. The protrusion is used for the threaded post 144 to rotate and move within the mounting post 2. The rotation of the transmission gear 141 drives the threaded sleeve 142 to rotate. The threaded sleeve 142 engages with the protrusion on the surface of the sliding column 143 through the threaded groove on its inner wall. Combined with the vertical sliding limit of the sliding column 143 and the mounting column 2, the sliding column 143 is driven to move down and press down the threaded groove column 144. The threaded groove column 144 engages with the protrusion on the inner wall of the lower end of the mounting column 2 through the threaded groove on its surface, and rotates to drill into the ground. The speed adjustment of the transmission gear 141 synchronously changes the drilling depth of the threaded groove column 144. The larger the diameter of the pile foundation column, the deeper the threaded groove column 144 drills, and the better the stability of the machine base 1.

[0020] Working principle: When using this pile foundation positioning and anti-deviation structure for pile foundation engineering, firstly, the base 1 is installed at the position of the pile foundation. Due to the unevenness of the ground, the spherical movable sleeve 6 makes adaptive circumferential angle adjustments within the opening of the platform 5. At the same time, the lower section of the guide tube 7 is designed to be longer and heavier than the upper section of the guide tube 7 of the movable sleeve 6. Therefore, under the action of gravity, in conjunction with the circumferential movement of the spherical movable sleeve 6, the guide tube 7 is always perpendicular to the ground, preventing the guide tube 7 from deviating and affecting the vertical positioning of the pile foundation column, thus achieving anti-deviation positioning of the pile foundation. Based on the above, when the guide tube 7 is perpendicular to the ground and remains stable, the motor drives the gear set to rotate the two sets of bidirectional threaded rods 8. The surfaces of the left and right sides of the bidirectional threaded rods 8 are designed with positive and negative threads, so that when the bidirectional threaded rods 8 rotate, they drive the left and right fixed plates 9 to move synchronously towards the middle until they come into contact and clamp from the left and right sides of the movable sleeve 6, thereby fixing the movable sleeve 6. Based on the above, the pile foundation column is vertically inserted from the upper end of the guide pipe 7. As the pile foundation column sinks vertically within the guide pipe 7, the four sets of contact blocks 138 are pushed outwards. The movement of the contact blocks 138 pushes the second plug 137 within the second oil tank 136. According to the diameter of the pile foundation column, the second plug 137 pushes out a corresponding volume of oil from the second oil tank 136. The oil enters the first oil tank 135 through the hose and pushes the first plug 134 within the first oil tank 135, thereby adjusting the position of the sliding plate 133. The block 131 and the bevel gear 12 slide on the surface of the slide plate 133 in conjunction with the sliding plate 133. At the same time, the block 131 adjusts its position along the inclined plate 132. As the bevel gear 12 moves along the inclined surface of the rack 10, the bevel gear 12 gradually changes from a smaller diameter meshing position with the transmission gear 141 to a larger diameter meshing position with the transmission gear 141. The change from a small diameter to a large diameter meshing position drives the transmission gear 141 to rotate, so that the rotation speed of the transmission gear 141 can be adaptively adjusted according to the diameter of the pile column. Based on the above, the rotation of the transmission gear 141 will drive the rotation of the threaded sleeve 142. The inner wall of the threaded sleeve 142 is designed with a threaded groove, and through cooperation with the protrusion on the surface of the sliding column 143, the sliding column 143 and the mounting column 2 slide vertically with a limit. The rotation of the threaded sleeve 142 causes the sliding column 143 to move downward along the mounting column 2, thereby pressing down the threaded groove column 144. The threaded groove on the surface of the threaded groove column 144 cooperates with the protrusion on the inner wall of the lower end of the mounting column 2, causing the threaded groove column 144 to rotate downward and drill into the ground. As the rotation speed of the transmission gear 141 is adjusted, the drilling depth of the threaded groove column 144 is adjusted. When the diameter of the pile column is large, the drilling depth of the threaded groove column 144 is deeper, which makes the stability of the base 1 better.
