Description

Technical Field

[0001] The present invention relates to the technical field of pile foundation construction, and more specifically to an anti-deviation device for pile foundation construction. Background Art

[0002] A pile foundation is a deep foundation composed of piles and a pile cap connecting the pile tops, or a single-pile foundation connecting columns and pile foundations. In high-rise building construction projects, pile foundations are widely used. The phenomenon of pile foundation deviation generally occurs due to poor site soil quality or large differences in soil quality. When the pile foundation deviates, the acting force of the upper load is not on the center line of the pile foundation, and the pile foundation is eccentrically compressed, which may cause the building to collapse in severe cases.

[0003] During the use of the existing pile foundation anti-deviation devices, although they can meet the basic anti-deviation support requirements, there are still many deficiencies. For example:

[0004] When installing the device, it is not convenient to level the device, which easily causes the device to be in an inclined state, making it difficult to achieve a good support and anti-deviation effect; when fixing the device, it is difficult to achieve a relatively stable fixing effect; the existing anti-deviation devices usually support the pile foundation after its installation and cannot support and limit it during the pile driving process of the pile foundation, with poor functionality.

[0016] The beneficial effects of the present invention compared with the prior art are:

[0017] 1. When the connecting screw rotates, the connection function of the two splicing bases can be realized through the connection with the thread groove. When one of the connecting screws rotates, it drives the rectangular sliding plate to move horizontally, so that the straight rack engages with the semi-circular rack, and then drives the rotating shaft to rotate through the meshing of the semi-circular rack and the transmission gear. With the help of the second synchronous pulley and the synchronous belt, the lifting screw is driven to rotate, driving the lifting plate to descend, and pushing a plurality of horizontal insertion rods to move synchronously away from the axis direction through the connecting rod, which not only realizes the connection of the two splicing bases, but also effectively improves the stability of the splicing base limit.

[0018] 2. After installing the two splicing leveling plates, observe the levelness through the electronic level body. Start the driving motor to drive the adjusting screw to rotate. With the help of the first synchronous pulley and the synchronous belt, and the connection of the cross-shaped block and the cross-shaped groove, the four square sliders move synchronously, driving the leveling roller to press the V-shaped inclined surface at the bottom of the splicing leveling plate to achieve precise leveling. This process greatly improves the installation efficiency, ensures the levelness of the splicing leveling plate, and provides a good foundation for subsequent work.

[0019] 3. When hoisting and installing the pile foundation, start the anti-deviation motor to drive the moving screw rod and bevel gear to rotate. Through the meshing of the bevel gear and the semi-circular bevel rack, the four convex sliders and the L-shaped sliding plate move synchronously towards the axis until the extrusion wheel contacts the outer wall of the circumferential side of the pile foundation. When the pressure values of the four pressure sensors are the same, the pile foundation is vertical. If the pile foundation is offset, the relative pressure sensor values change. At this time, start the adjustment motor to drive the adjustment screw rod, so that the relative two lifting blocks rise and fall respectively, and extrude the pile foundation to make it return to vertical, thus effectively ensuring the verticality of the pile foundation installation, improving the quality and safety of the pile foundation installation, and reducing the potential risks brought by the pile foundation offset.

Specific embodiments

[0034] The following further describes the present invention in conjunction with specific embodiments. However, those skilled in the art should understand that the detailed description given here in conjunction with the drawings is for better explanation. The structure of the present invention necessarily goes beyond these limited embodiments, and for some equivalent replacement schemes or common means, no detailed description will be given herein, but they still fall within the protection scope of this application.

[0035] Figures 1 - 13 is the best embodiment of the present invention. The following further describes the present invention in conjunction with the attached Figures 1 - 13 drawings.

[0036] A pile foundation construction anti-deviation device includes two splicing bases 1, which are connected by a connection mechanism. A leveling mechanism is jointly arranged in the two splicing bases 1. The leveling mechanism includes two leveling rollers 13, and the two leveling rollers 13 are respectively slidably arranged in the two splicing bases 1. The two leveling rollers 13 are symmetrically arranged. The leveling mechanism further includes two splicing leveling plates 2, and the two splicing leveling plates 2 are respectively clamped to the two splicing bases 1 through a clamping mechanism. Pointed insertion rods 3 are fixedly installed at the bottoms of the two splicing bases 1, and a limiting mechanism is arranged in each of the two pointed insertion rods 3. The limiting mechanism includes four horizontal insertion rods 23. Cross-shaped sliding holes are formed in the peripheral outer walls of the pointed insertion rods 3, and the four horizontal insertion rods 23 are all slidably installed in the cross-shaped sliding holes. A control mechanism is jointly arranged on the peripheral outer walls of the four horizontal insertion rods 23, and the control mechanism is connected to the connection mechanism. An anti-deviation mechanism is jointly arranged on the tops of the two splicing leveling plates 2. The anti-deviation mechanism includes four lifting blocks 49, and the four lifting blocks 49 are connected through an adjusting component. Pressing wheels 54 are slidably arranged on the sides of the four lifting blocks 49 through an induction component.

[0037] With the above structure, during use, after connecting the two splicing bases 1 through the connection mechanism and placing them at the construction position, after connecting the two splicing leveling plates 2, they are clamped and installed on the two splicing bases 1 through the clamping mechanism. By driving the two leveling rollers 13 to move synchronously through the leveling mechanism, through the extrusion effect with the two splicing leveling plates 2, the horizontal adjustment function can be realized, which is convenient for preventing deviation during pile foundation installation. And when connecting the two splicing bases 1, through the connection between the connection mechanism and the control mechanism, the fixed limiting function of the two splicing bases 1 can be realized. After the horizontal adjustment is completed, through the action of the adjusting component, the four lifting blocks 49 and the four pressing wheels 54 are driven to move towards each other synchronously, realizing the extrusion anti-deviation function of the pile foundation. Through the setting of the induction component, when the pile foundation descends and deviates, the pile foundation can be adjusted in time, and the functionality is relatively strong.

[0038] As Figure 5 and Figure 6 As shown, the connection mechanism includes two connection screws 14. Rectangular sliding grooves are formed in the mutually adjacent sides of the two splicing bases 1. Threaded holes are formed in the inner walls of the sides of two of the rectangular sliding grooves, and threaded grooves are formed in the inner walls of the sides of the other two rectangular sliding grooves. The two connection screws 14 are respectively threadedly installed in the two threaded holes. One ends of the two connection screws 14 extend outside the threaded holes and are fixedly installed with plum blossom knobs 15. The other ends of the two connection screws 14 are respectively threadedly installed in the two threaded grooves. Rectangular sliding plates 16 are rotatably installed on the peripheral outer walls of the two connection screws 14, and the two rectangular sliding plates 16 are respectively adapted to the four rectangular sliding grooves. Through the threaded connection function of the two connection screws 14 with the two threaded holes and the two threaded grooves, the fixed connection function of the two splicing bases 1 can be realized when the connection screws 14 are rotated, and the connection effect is relatively stable.

[0039] Specifically, rotate the plum blossom knob 15 to drive the connecting screw 14 to rotate. Through the connection between the connecting screw 14 and the threaded hole, the connecting screw 14 can be driven to move horizontally until the connecting screw 14 is threadedly connected to the threaded groove, thereby realizing the fixed connection function of the two splicing bases 1.

[0040] Such as Figure 1 、 Figure 2 and Figure 3 shown, the leveling mechanism further includes four square sliders 6. Sliding grooves are provided on the opposite inner walls of the two splicing bases 1. Circular holes are provided on the inner walls of one side of the four sliding grooves. Adjusting screws 7 are rotatably installed in the four circular holes. The four adjusting screws 7 are connected by a linkage component. The four square sliders 6 are respectively threadedly installed on the four adjusting screws 7. Connecting shafts 12 are rotatably installed together on the opposite side parts of each pair of matching square sliders 6. Two leveling rollers 13 are respectively fixedly sleeved on the outer walls of the circumferences of the two connecting shafts 12. The bottoms of the two splicing leveling plates 2 are both provided with V-shaped inclined surfaces. The bottom inclined surfaces of the two splicing leveling plates 2 are respectively in contact with the outer walls of the circumferences of the two leveling rollers 13. An electronic level body 5 is fixedly installed on the top of one of the splicing leveling plates 2. Specifically, the electronic level body 5 can adopt an improved electronic level disclosed in the prior art with the publication number of CN217980297U. Its specific working principle will not be elaborated here. Through the arrangement of multiple adjusting screws 7, it is possible to drive multiple square sliders 6 to move horizontally synchronously, thereby driving the two connecting shafts 12 and the two leveling rollers 13 to move horizontally synchronously, and thus realizing the horizontal adjustment function through the extrusion effect on the splicing leveling plate 2.

[0041] Specifically, when the four adjusting screws 7 rotate synchronously, the four square sliders 6 can be driven to move horizontally synchronously through the threading effect, thereby driving the two connecting shafts 12 and the two leveling rollers 13 to move horizontally synchronously to realize the leveling function.

[0042] Such as Figure 2 and Figure 4As shown, the linkage assembly includes two cross-shaped blocks 11. One end of each of the two adjusting screws 7 is rotatably installed on the inner wall of the side of the two sliding grooves. A transmission cavity is formed in one of the splicing bases 1. One end of the remaining two adjusting screws 7 extends into the transmission cavity and is fixedly sleeved with a first synchronous pulley 8. A first synchronous belt 9 is commonly engaged and installed on the two first synchronous pulleys 8. A driving motor 10 is fixedly installed on the side of one of the splicing bases 1. Specifically, the driving motor 10 can be controlled by a PLC controller. The output shaft of the driving motor 10 is connected to the end of one of the adjusting screws 7. The sides of the two cross-shaped blocks 11 are respectively fixedly connected to the ends of two of the adjusting screws 7. Cross-shaped grooves are formed at the ends of the other two adjusting screws 7. The two cross-shaped blocks 11 respectively correspond to the two cross-shaped grooves. Through the setting of the cross-shaped blocks 11 and the cross-shaped grooves, the connection function of the two adjusting screws 7 can be realized, so that when one of the adjusting screws 7 rotates, it drives the other adjusting screw 7 to rotate synchronously.

[0043] Specifically, when installing the two splicing bases 1, the two cross-shaped blocks 11 can be respectively clamped with the two cross-shaped grooves, so that when two of the adjusting screws 7 rotate, they can drive the other two adjusting screws 7 to rotate synchronously.

[0044] As Figure 10 and Figure 11 shown, the clamping mechanism includes a mounting shaft 30. A mounting groove is formed at the top of the splicing adjusting plate 2. A through hole is formed in the inner wall of the side of the mounting groove. The mounting shaft 30 is slidably installed in the through hole. Semi-circular clamping grooves are formed in the inner walls of the sides of the two splicing bases 1. One end of the mounting shaft 30 extends into the two semi-circular clamping grooves. The other ends of the two mounting shafts 30 extend into the mounting groove and are fixedly connected with an operation plate 31. A compression spring 32 is arranged on the side of the operation plate 31. The other end of the compression spring 32 is fixedly installed on the inner wall of the side of the mounting groove. Through the setting of the two mounting shafts 30, the installation function of the two splicing adjusting plates 2 can be realized, so that after the splicing adjusting plates 2 are installed, they can still rotate, so as to realize the horizontal adjustment function. A plurality of connecting plates 34 are arranged on the tops of the two splicing adjusting plates 2. Connecting holes are formed in the sides of the plurality of connecting plates 34. Fixing bolts 33 are arranged in each pair of adapted connecting holes. Nuts are threaded on the plurality of fixing bolts 33. A plurality of guide shafts 35 are fixedly installed on the sides of the two splicing adjusting plates 2 close to each other. A plurality of guide grooves 36 are formed in the sides of the two splicing adjusting plates 2 close to each other. The plurality of guide shafts 35 are respectively arranged corresponding to the plurality of guide grooves 36.

[0045] Specifically, by moving the two mounting shafts 30 towards each other, the two splicing leveling plates 2 can be installed into the two splicing bases 1, thereby realizing the installation function of the two splicing leveling plates 2. When the two mounting shafts 30 are released, the elastic action of the two compression springs 32 can drive the two mounting shafts 30 to reset synchronously, thereby realizing the clamping function with multiple semi-circular grooves.

[0046] As Figure 7 and Figure 9 shown, the control mechanism includes a lifting screw 24. A circular cavity is formed in the pointed plug 3. The bottom end of the lifting screw 24 is rotatably installed on the inner wall of the bottom end of the circular cavity. A rectangular cavity is formed in the splicing base 1. The top end of the lifting screw 24 penetrates into the rectangular cavity and is rotatably installed on the inner wall of the top of the rectangular cavity. Four connecting grooves are formed in the bottom inner wall of the circular cavity. The four connecting grooves are all communicated with the cross-shaped sliding holes. Four U-shaped blocks 28 are slidably installed in the four connecting grooves. The bottom ends of the four U-shaped blocks 28 are respectively fixedly connected to the outer walls of the circumferences of the four horizontal plug rods 23. The opposite inner walls of the four U-shaped blocks 28 are rotatably installed with connecting rods 29. The outer wall of the circumference of the lifting screw 24 is threadedly installed with lifting plates 27. Rotating grooves are formed in the four side parts of the lifting plates 27. The other ends of the four connecting rods 29 are respectively rotatably installed in the four rotating grooves. With such a setting, through the connection action of the multiple connecting rods 29, when the lifting plate 27 moves downward, it can drive the multiple horizontal plug rods 23 to move synchronously away from the axis direction and insert into the ground, improving the fixing function of the splicing base 1.

[0047] Specifically, when the lifting screw 24 rotates, the lifting plate 27 can be driven to move downward through the threaded action. Thus, under the connection action of the four connecting rods 29, the four U-shaped blocks 28 and the four horizontal plug rods 23 are driven to move synchronously away from the axis direction, thereby improving the fixing and limiting function of the splicing base 1.

[0048] As Figure 6 , Figure 7 and Figure 8As shown in the figure, the control mechanism further includes two first semi-circular rotating plates 18. First semi-circular grooves are formed on the side parts of the two splicing bases 1 close to each other. The two first semi-circular grooves are respectively communicated with four rectangular sliding grooves and two rectangular cavities. First limiting grooves are formed on the circumferential inner walls of the two first semi-circular grooves. First semi-circular limiting blocks 19 are rotatably installed in the two first limiting grooves. The circumferential inner walls of the two first semi-circular rotating plates 18 are fixedly connected to the circumferential outer walls of the two first semi-circular limiting blocks 19 respectively. Semi-circular racks 20 are fixedly arranged on the circumferential outer walls of the two first semi-circular rotating plates 18. A straight rack 17 is fixedly installed on the side part of one of the rectangular sliding plates 16. The straight rack 17 is meshed and installed with the two semi-circular racks 20. The control mechanism further includes a rotating shaft 21. The two ends of the rotating shaft 21 are respectively rotatably installed on the opposite inner walls of the rectangular cavity. A transmission gear 22 is fixedly sleeved on the circumferential outer wall of the rotating shaft 21. The transmission gear 22 is meshed and installed with the two semi-circular racks 20. Second synchronous belt wheels 25 are fixedly sleeved on the circumferential outer walls of the rotating shaft 21 and the lifting screw rod 24 respectively. A second synchronous belt 26 is meshed and installed on the two second synchronous belt wheels 25. Through the meshing actions of the two semi-circular racks 20, the straight rack 17, the two second synchronous belt wheels 25 and the second synchronous belt 26, when connecting the two splicing bases 1, the fixed limiting function of the splicing bases 1 can be strengthened synchronously.

[0049] Specifically, when one of the connecting screw rods 14 rotates, it can drive one of the rectangular sliding plates 16 and the straight rack 17 to move synchronously. Then, through the meshing action of the straight rack 17 and the two semi-circular racks 20, the transmission gear 22 is driven to rotate. By the rotation of the transmission gear 22, the rotating shaft 21 is driven to rotate, and under the meshing action of the two second synchronous belt wheels 25 and the second synchronous belt 26, the lifting screw rod 24 is driven to rotate.

Through the meshing action of the multiple bevel gears 42 and the two semi-circular bevel racks 45, when one of the moving screws 40 rotates, it can drive the other three moving screws 40 to rotate synchronously, thereby realizing the synchronous adjustment function of the four extrusion wheels 54.

[0051] Specifically, start one of the deviation prevention motors 46 to drive one of the moving screws 40 and the bevel gear 42 to rotate synchronously. Then, through the meshing action of the bevel gear 42 and the two semi-circular bevel racks 45, drive the other three bevel gears 42 to rotate synchronously, thereby driving the other three moving screws 40 to rotate synchronously. Through the thread action, drive the four extrusion wheels 54 to realize the synchronous movement function.

[0052] As Figure 12 and Figure 13 As shown in the figure, the adjustment component further includes four convex sliders 41. The four convex sliders 41 are respectively slidably installed in the four convex grooves and are respectively threadedly connected to the four moving screws 40. L-shaped sliding plates 38 are fixedly installed on the tops of the four convex sliders 41. Reinforcing shafts 39 are fixedly arranged on both sides of the four L-shaped sliding plates 38. Lifting grooves are provided on the sides of the four L-shaped sliding plates 38. Adjusting screws 47 are rotatably installed on the opposite inner walls of the four lifting grooves. Adjusting motors 48 are fixedly installed on the tops of the four L-shaped sliding plates 38. Specifically, the multiple adjusting motors 48 are all controlled by a PLC controller. The output shafts of the four adjusting motors 48 are respectively connected to the tops of the four adjusting screws 47. Four lifting blocks 49 are respectively threadedly installed on the four adjusting screws 47. Through the arrangement of the four L-shaped sliding plates 38, the position of the four extrusion wheels 54 can be adjusted, which is convenient for adapting to piles with different diameters.

[0053] Specifically, when the four moving screws 40 rotate synchronously, they can drive the four convex sliders 41, the four L-shaped sliding plates 38, and the four pressing wheels 54 to achieve synchronous movement functions, so as to adapt to pile foundations with different diameters.

[0054] As Figure 13 shown, the induction component includes a pressure sensor 51. Specifically, the pressure sensor 51 is controlled by a PLC controller. A square groove is provided on the side of the lifting block 49. The pressure sensor 51 is fixedly installed on the inner wall of the side of the square groove. A square sliding rod 50 is slidably installed in the square groove. One end of the square sliding rod 50 extends outside the square groove and is fixedly installed with a U-shaped plate 52. A return spring 53 is sleeved on the outer wall of the circumferential side of the square sliding rod 50. A rotating rod is rotatably installed on the opposite inner walls of the U-shaped plate 52. The pressing wheel 54 is fixedly sleeved on the rotating rod. Through the settings of the pressure sensor 51 and the lifting block 49, while detecting the inclination of the pile foundation, the angle of the pile foundation can be corrected through the lifting action of the pressing wheel 54, and the functionality is relatively strong.

[0055] The working principle and usage process of the present invention: When in use, first move the two splicing bases 1 to the construction position. After inserting the two cross-shaped blocks 11 into the two cross-shaped slots, place the splicing base 1 on the construction position, so that the two pointed insertion rods 3 are inserted into the ground respectively, realizing the fixing function of the splicing base 1. Rotate the two plum blossom knobs 15 respectively to drive the two connecting screws 14 to rotate synchronously. Through the threaded action of the connecting screw 14 and the threaded hole, the two connecting screws 14 can move horizontally synchronously until they are respectively threadedly connected to the two threaded slots, completing the connection operation of the two splicing bases 1.

[0056] When the two connecting screws 14 are moving, they can drive the two rectangular sliding plates 16 to move synchronously respectively. When one of the rectangular sliding plates 16 moves horizontally, it can drive the straight rack 17 to move synchronously, so that the straight rack 17 is meshed and installed with the two semi-circular racks 20, thereby driving the two first semi-circular rotating plates 18 and the two semi-circular racks 20 to rotate synchronously. When the two semi-circular racks 20 rotate, they are engaged with the two transmission gears 22 to drive the two rotating shafts 21 to rotate. When the rotating shaft 21 rotates, through the meshing action of the two second synchronous belt wheels 25 and the second synchronous belt 26, the lifting screw 24 can be driven to rotate. When the lifting screw 24 rotates, through the threaded action, the lifting plate 27 can be driven to move downward. Through the connection action of the four connecting rods 29, the four U-shaped blocks 28 and the four horizontal insertion rods 23 can be driven to move synchronously away from the axis direction, thereby strengthening the limiting function of the splicing base 1.

[0057] Align the multiple guide shafts 35 and multiple guide grooves 36 on the two splicing leveling plates 2 one by one, and then fix and connect the two splicing leveling plates 2 through the action of multiple fixing bolts 33 and multiple connecting plates 34. Slide the two operating plates 31 towards each other, thereby driving the two mounting shafts 30 to move towards each other synchronously. After moving the two splicing leveling plates 2 to an appropriate position, release the limit on the two operating plates 31, so that the two mounting shafts 30 are driven to reset under the elastic action of the two compression springs 32, realizing the clamping function with multiple semi-circular clamping grooves, and completing the installation of the splicing leveling plates 2. After the installation is completed, the electronic level body 5 can observe the levelness of the splicing leveling plates 2. Then start the driving motor 10 to drive one of the adjusting screws 7 to rotate, and then drive the other adjusting screw 7 to achieve synchronous rotation function under the meshing action of the two first synchronous belt wheels 8 and the first synchronous belt 9. And through the connection action of the two cross-shaped blocks 11 and the two cross-shaped grooves, it can drive the other two adjusting screws 7 to rotate synchronously, so that the four square sliders 6 move horizontally synchronously, and then drive the two connecting shafts 12 and the two leveling rollers 13 to move horizontally synchronously. Through the extrusion action between the two leveling rollers 13 and the V-shaped inclined surfaces at the bottom of the two splicing leveling plates 2 during horizontal movement, the two splicing leveling plates 2 can be driven to tilt at a certain angle until the electronic level body 5 is in a horizontal state.

[0058] Lift the pile foundation above the splicing base 1 and align it with the position of the central hole. Start the anti-deviation motor 46 to drive one of the moving screws 40 and the bevel gear 42 to rotate, so that through the meshing action of the bevel gear 42 and the two semi-circular bevel racks 45, drive the other three bevel gears 42 and the other three moving screws 40 to rotate synchronously, and then drive the four convex sliders 41 and the four L-shaped sliding plates 38 to move towards the axis direction through the thread action until the four pressing wheels 54 all contact the outer wall of the pile foundation. At this time, the four L-shaped sliding plates 38 continue to move, causing the four pressure sensors 51 to contact the four square sliding rods 50. When the pressure values on the four pressure sensors 51 are the same, the pile foundation is in a vertical state. At this time, install the pile foundation downward. When the pile foundation has a certain deviation phenomenon, the values on the opposite pressure sensors 51 will increase or decrease accordingly. At this time, start the adjustment motor 48 to drive the adjustment screw 47 to rotate, which can drive the lifting block 49 to achieve the lifting function. When one of the two opposite lifting blocks 49 rises and the other descends, the pile foundation can be squeezed, so that it returns to vertical and realizes the anti-deviation function.
