Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a verticality control device for pipe pile driving. Background Technology

[0002] In the field of construction engineering, pipe pile driving is a crucial foundational operation. With the continuous development of the construction industry, the requirements for the quality and efficiency of pipe pile driving are becoming increasingly stringent. The verticality of the pipe piles directly affects the stability and safety of the building. Significant deviations in verticality can lead to uneven settlement of the foundation, thereby impacting the overall structural safety. Simultaneously, accurately controlling the verticality of the pipe piles helps improve construction efficiency, reduce subsequent correction and repair work, and lower construction costs. Therefore, effectively controlling the verticality during pipe pile driving has become a key issue in the construction industry.

[0003] In traditional pipe pile driving construction, the verticality of the pipe pile is usually controlled by manual observation and adjustment based on the experience of the construction workers. The construction workers visually observe the inclination of the pipe pile, use simple measuring tools such as plumb lines to roughly judge the verticality of the pipe pile, and then try to keep the pipe pile vertical by adjusting the position and angle of the crane.

[0004] However, relying on manual observation and adjustment methods has low accuracy and reliability, and cannot provide real-time and precise control over the verticality of pipe piles, so it needs to be improved. Summary of the Invention

[0005] To address the problem of the inability to control the verticality of sinking pipe piles, this application provides a verticality control device for pipe pile driving.

[0006] The verticality control device for pipe pile driving provided in this application adopts the following technical solution: A verticality control device for driving pipe piles includes a base plate, a limiting frame, and a lifting rope. The limiting frame is disposed on the base plate, the pipe pile passes through the limiting frame, and the inner wall of the limiting frame abuts against the side wall of the pipe pile. The lifting rope is connected to a crane, and the end of the lifting rope away from the crane is connected to the pipe pile through an installation component.

[0007] By adopting the above technical solution, during installation, the installation components are installed on the pipe pile, and the hoisting rope is connected to the pipe pile. Then, the crane is started, and the hoisting rope drives the pipe pile up and down, aligning the pipe pile with the base plate and passing it through, so that the pipe pile is inserted into the limiting frame. At this time, the inner wall of the limiting frame is in contact with the pipe pile, thereby limiting the pipe pile. The installation components and the limiting frame serve as two limiting points for the pipe pile, realizing the control of the verticality of the pipe pile, thus ensuring that the pipe pile is installed at the preset point and increasing the stability of the vertical installation of the pipe pile.

[0008] Optionally, the installation assembly includes an installation block, a wire rope, and a clamp. The installation block is fixed to the end of the hoisting rope away from the crane. One end of the wire rope is fixed to the installation block, and the other end is fixed to the clamp. The clamp is fixedly sleeved on the pipe pile.

[0009] By adopting the above technical solution, the installation block serves as an intermediate component connecting the hoisting rope and the wire rope. The wire rope connects the installation block and the clamp, and the clamp is fixed to the pipe pile, thereby realizing the connection between the hoisting rope and the pipe pile. This allows the crane's power to be stably transmitted to the pipe pile, enabling the lifting and transportation of the pipe pile.

[0010] Optionally, the mounting block is provided with an adjustment assembly for driving the pipe pile into a vertical state. The adjustment assembly includes an adjustment block, a driving member, and two adjustment rods. The adjustment block is located on the mounting block, the driving member is located on the adjustment block, and the two adjustment rods are connected by a connecting rod. The pipe pile is located between the two adjustment rods. The driving member is connected to the middle part of the connecting rod. The driving member is used to drive the connecting rod to rotate about the middle part of the connecting rod as an axis. The adjustment rod can abut against the pipe pile.

[0011] By adopting the above technical solution, after the pipe pile is fixed with a clamp, when the pipe pile is in a vertical state, it is located in the middle of the two adjusting rods. When the pipe pile deviates, that is, the pipe pile deflects about the connection between the pipe pile and the clamp, causing the pipe pile to push against the driving component in the direction of deflection. This causes the driving component to start and drive the connecting rod to rotate, thereby driving the two adjusting rods to make circular motion. That is, the two adjusting rods, which were originally symmetrical in the horizontal direction, gradually move towards the vertical direction. Specifically, one adjusting rod moves upward and the other moving downward, until one adjusting rod abuts against the pipe pile and applies a pushing force to the pipe pile, driving the pipe pile back to a vertical state. At this time, the driving component loses power and drives the connecting rod to reset, so that the connecting rod returns to a symmetrical state in the horizontal direction. The entire process uses the abutment between the adjusting rod and the pipe pile to adjust the verticality of the pipe pile, avoid the pipe pile from deviating, and improve the stability of the pipe pile's fixed-point installation.

[0012] Optionally, a rubber sleeve is fitted onto the adjusting rod.

[0013] By adopting the above technical solution, the rubber sleeve has elasticity and anti-slip properties, which can increase the friction between the adjusting rod and the pipe pile, while avoiding damage to the surface of the pipe pile by the adjusting rod.

[0014] Optionally, the driving component includes a moving gear, a moving rack, and two driving rods. The moving gear is rotatably connected to the adjusting block and fixed to the middle of the connecting rod. The moving rack is horizontally disposed on the adjusting block and can slide on the adjusting block. The moving rack meshes with the moving gear. The driving rods are fixedly connected to the moving rack. The pipe pile is located between the two driving rods, and both driving rods abut against the side wall of the pipe pile.

[0015] By adopting the above technical solution, when the pipe pile deflects, the pipe rotation drives the drive rod to move, thereby driving the moving rack to slide on the adjusting block, driving the moving gear to rotate, and then causing the connecting rod to rotate, so that the adjusting rod abuts against the pipe pile and pushes the pipe pile to achieve the adjustment of the verticality of the pipe pile.

[0016] Optionally, the mounting block is equipped with a rotary motor, which is coaxial with the pipe pile and fixed to the adjusting block, for driving the adjusting block to rotate about the pipe as the axis.

[0017] By adopting the above technical solution, when the rotary motor is working, it drives the adjusting block to rotate, thereby enabling the adjusting component to adjust the verticality of the pipe pile at different angles.

[0018] Optionally, a mounting hole is provided through the substrate, a limiting frame is provided on the bottom wall of the substrate, and the limiting frame is coaxial with the mounting hole. A limiting component is provided in the mounting hole, and the limiting component is used to limit the displacement of the pipe pile in the mounting hole.

[0019] By adopting the above technical solution, when the pipe pile passes through the base plate and through the center of the limiting frame, the limiting component abuts against the side wall of the pipe pile, which plays a limiting role, preventing the pipe pile from shifting and causing the limiting frame to deform, and further improving the stability of the vertical fixed-point installation of the pipe pile.

[0020] Optionally, the limiting component includes a limiting ring and a plurality of limiting rods. The limiting ring is coaxial with the mounting hole, and the limiting rods are located between the limiting ring and the inner wall of the mounting hole. One end of the limiting rod is hinged to the inner wall of the mounting hole by a torsion spring, and the other end is hinged to the limiting ring. The plurality of limiting rods are arranged radially with the center of the limiting ring as the center.

[0021] By adopting the above technical solution, when the pipe pile passes through the limiting ring, the inner wall of the limiting ring abuts against the side wall of the pipe pile. When the pipe pile deviates horizontally, it drives the limiting ring to move in the mounting hole, causing the distance between the limiting ring and the inner wall of the mounting hole to change. This causes the limiting rod to rotate, driving the torsion spring to deform. The elastic force of the torsion spring causes the limiting rod to always apply a restoring thrust to the limiting ring, thereby correcting the position of the pipe pile and improving the verticality of the pipe pile.

[0022] Optionally, the limiting rod includes a positioning rod and a positioning sleeve. One end of the positioning rod is connected to a torsion spring, and the other end is inserted into the positioning sleeve. The end of the positioning sleeve away from the positioning rod is hinged to a limiting ring. A spring is provided inside the positioning sleeve, and the spring is sleeved on the positioning rod.

[0023] By adopting the above technical solution, when the pipe pile deviates, the positioning rod slides in the positioning sleeve, the spring plays a buffering role, and the torsion spring will also generate a corresponding torsional force, further improving the correction force for the deviated pipe pile and facilitating the correction of the verticality of the pipe pile.

[0024] Optionally, the limiting ring is provided with a plurality of rollers, which are capable of rotating on the limiting ring.

[0025] By adopting the above technical solution, the friction between the pipe pile and the limiting ring is reduced, allowing the pipe pile to pass through the limiting ring more smoothly during the pile driving process.

[0026] In summary, this application includes at least one of the following beneficial effects: 1. During installation, the installation components are installed on the pipe pile, and the hoisting rope is connected to the pipe pile. Then, the crane is started, and the hoisting rope is driven to move the pipe pile up and down, so that the pipe pile is aligned with the base plate and passes through, so that the pipe pile is inserted into the limiting frame. At this time, the inner wall of the limiting frame is in contact with the pipe pile, thereby limiting the pipe pile. The installation components and the limiting frame serve as two limiting points for the pipe pile, thereby controlling the verticality of the pipe pile and ensuring that the pipe pile is installed at the preset point, which increases the stability of the vertical installation of the pipe pile. 2. After the pipe pile is fixed in place with the clamp, when the pipe pile is vertical, it is located in the middle of the two adjusting rods. When the pipe pile shifts, that is, the pipe pile deflects about the connection between the pipe pile and the clamp, causing the pipe pile to push against the driving component in the direction of deflection. This causes the driving component to start and drive the connecting rod to rotate, thereby driving the two adjusting rods to make circular motion. That is, the two adjusting rods, which were originally symmetrical in the horizontal direction, gradually move towards the vertical direction. Specifically, one adjusting rod moves upward and the other moves downward until one adjusting rod abuts against the pipe pile and applies a pushing force to the pipe pile, driving the pipe pile back to the vertical position. At this time, the driving component loses power and drives the connecting rod to reset, so that the connecting rod returns to the symmetrical state in the horizontal direction. The whole process uses the abutment between the adjusting rod and the pipe pile to adjust the verticality of the pipe pile, avoid the pipe pile shifting, and improve the stability of the pipe pile fixed-point installation.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses a verticality control device for pipe pile driving. (Refer to...) Figure 1 and Figure 2 The verticality control device for pipe pile driving includes a base plate 10, a limiting frame 11, and a lifting rope 20. The limiting frame 11 is mounted on the base plate 10, and the pipe pile passes through the limiting frame 11. The inner wall of the limiting frame 11 abuts against the side wall of the pipe pile, which can limit the horizontal displacement of the pipe pile and prevent the pipe pile from swaying significantly in the horizontal direction. The lifting rope 20 is connected to a crane, and the end of the lifting rope 20 away from the crane is connected to the pipe pile through an installation assembly 30 to realize the lifting and transportation of the pipe pile.

[0031] Reference Figure 1 and Figure 2 Specifically, the installation component 30 includes an installation block 31, a wire rope 32, and a clamp 33. The installation block 31 is fixed to the end of the lifting rope 20 furthest from the crane. One end of the wire rope 32 is fixed to the installation block 31, and the other end is fixed to the clamp 33. The wire rope 32 has good flexibility and strength, ensuring connection stability. The clamp 33 is fixedly fitted onto the pipe pile. The clamp 33 is generally composed of two semi-circular metal plates, which are fastened to the pipe pile with bolts. Alternatively, the clamp 33 can also be made of steel strip. The installation block 31 serves as an intermediate component connecting the lifting rope 20 and the wire rope 32. The wire rope 32 connects the installation block 31 and the clamp 33, and the clamp 33 is fixed to the pipe pile, thus achieving the connection between the lifting rope 20 and the pipe pile. This allows for the stable transmission of the crane's force to the pipe pile, enabling the lifting of the pipe pile.

[0032] Reference Figure 2 and Figure 3Specifically, the mounting block 31 is equipped with an adjustment assembly 40 for driving the pipe pile into a vertical position. The adjustment assembly 40 includes an adjustment block 41, a driving member 42, and two adjustment rods 43. The adjustment block 41 is fixed to the mounting block 31 by bolts. The driving member 42 is mounted on the adjustment block 41 and is used to provide power. The two adjustment rods 43 are connected by a connecting rod 44, and the pipe pile is located between the two adjustment rods 43. The driving member 42 is connected to the middle of the connecting rod 44, and the driving member 42 is used to drive the connecting rod 44 to rotate about the middle of the connecting rod 44 as an axis. The adjustment rods 43 can abut against the pipe pile.

[0033] After the pipe pile is fixed in place by the clamp 33, when the pipe pile is in a vertical position, it is located in the middle of the two adjusting rods 43, meaning there is a gap between the pipe pile and the adjusting rods 43. When the pipe pile shifts, that is, when the pipe pile deflects about the connection point between the pipe pile and the clamp 33, the pipe pile pushes against the driving component 42 in the direction of deflection. This causes the driving component 42 to start and drive the connecting rod 44 to rotate, thereby driving the two adjusting rods 43 to make circular motion. That is, the two adjusting rods 43, which were originally symmetrical in the horizontal direction, gradually move towards the vertical direction. Specifically, one adjusting rod 43 moves upward and the other adjusting rod 43 moves downward, until one adjusting rod 43 abuts against the pipe pile and applies a pushing force to the pipe pile, driving the pipe pile back to a vertical position. At this time, the driving component 42 loses power and drives the connecting rod 44 to reset, so that the connecting rod 44 returns to a symmetrical state in the horizontal direction.

[0034] Throughout the process, the adjusting block 41 provides the mounting base for the driving component 42. The driving component 42 drives the connecting rod 44 and the adjusting rod 43 to move. The adjusting rod 43 abuts against the pipe pile to adjust the verticality of the pipe pile. Thus, the precise control of the driving component 42 and the abutment method between the adjusting rod 43 and the pipe pile enable the adjustment of the pipe pile's minute angle, thereby accurately adjusting the verticality of the pipe pile.

[0035] Reference Figure 2 and Figure 3 Specifically, a rubber sleeve 431 is fitted onto the adjusting rod 43. The rubber sleeve 431 is elastic and non-slip, which increases the friction between the adjusting rod 43 and the pipe pile, while preventing the adjusting rod 43 from damaging the surface of the pipe pile. The rubber sleeve 431 can be fitted onto the adjusting rod 43 by interference fit, and can be replaced or fixed by adhesive.

[0036] Reference Figure 2 and Figure 3Specifically, the driving component 42 includes a movable gear 421, a movable rack 422, and two driving rods 423. The movable gear 421 is rotatably connected to the adjusting block 41, and can be connected to the adjusting block 41 via bearings to ensure its flexible rotation. The movable gear 421 is fixed to the middle of the connecting rod 44. The movable rack 422 is horizontally arranged on the adjusting block 41 and can slide on the adjusting block 41. The movable rack 422 meshes with the movable gear 421. The driving rods 423 are fixedly connected to the movable rack 422. The pipe pile is located between the two driving rods 423, and both driving rods 423 abut against the side wall of the pipe pile.

[0037] When the pipe pile deflects, the pipe rotation drives the drive rod 423 to move, which in turn drives the moving rack 422 to slide on the adjusting block 41, driving the moving gear 421 to rotate, which in turn causes the connecting rod 44 to rotate, so that the adjusting rod 43 abuts against the pipe pile and pushes the pipe pile to achieve the adjustment of the verticality of the pipe pile.

[0038] Reference Figure 2 and Figure 3 Specifically, a rotary motor 311 is mounted on the mounting block 31. The rotary motor 311 is coaxial with the pipe pile and fixed to the adjusting block 41, driving the adjusting block 41 to rotate around the pipe pile as its axis. The rotary motor 311 can be bolted to the mounting block 31, and its output shaft is connected to the adjusting block 41. When the rotary motor 311 is working, it drives the adjusting block 41 to rotate, thereby enabling the adjusting assembly 40 to adjust the verticality of the pipe pile at different angles. The rotary motor 311 increases the adjustment range and flexibility of the adjusting assembly 40, better handling the offset of the pipe pile in different directions.

[0039] Reference Figure 1 and Figure 3 Specifically, a mounting hole 12 is formed through the substrate 10, and a limiting frame 11 is disposed on the bottom wall of the substrate 10, and the limiting frame 11 is coaxial with the mounting hole 12. A limiting component 50 is provided in the mounting hole 12, which is used to limit the displacement of the pipe pile in the mounting hole 12. The limiting component 50 includes a limiting ring 51 and several limiting rods 52. The limiting ring 51 is coaxial with the mounting hole 12, and the limiting rods 52 are located between the limiting ring 51 and the inner wall of the mounting hole 12. One end of the limiting rod 52 is hinged to the inner wall of the mounting hole 12 by a torsion spring 53, and the other end is hinged to the limiting ring 51. Several limiting rods 52 are arranged radially with the center of the limiting ring 51 as the center.

[0040] Reference Figure 1 and Figure 3The limiting rod 52 causes the limiting ring 51 to move and deform accordingly when the pipe pile deviates, thus limiting the pipe pile. When the pipe pile deviates, the limiting rod 52 causes the limiting ring 51 to move through the torsion spring 53, limiting the pipe pile. The cooperation between the limiting rod 52 and the limiting ring 51 can respond promptly according to the pipe pile's deviation, thereby limiting the pipe pile's deviation in real time during the pile driving process.

[0041] Reference Figure 1 and Figure 3 Specifically, the limiting rod 52 includes a positioning rod 521 and a positioning sleeve 522. One end of the positioning rod 521 is connected to a torsion spring 53, and the other end is inserted into the positioning sleeve 522. The end of the positioning sleeve 522 away from the positioning rod 521 is hinged to the limiting ring 51. A spring 523 is provided inside the positioning sleeve 522 and is sleeved on the positioning rod 521. The positioning rod 521 and the positioning sleeve 522 are made of metal, and the spring 523 provides cushioning and elasticity. When the pipe pile deviates, the positioning rod 521 slides in the positioning sleeve 522, the spring 523 plays a cushioning role, and the torsion spring 53 also generates a corresponding torsional force. The combination logic of positioning rod 521, positioning sleeve 522 and spring 523 is as follows: the sliding fit of positioning rod 521 and positioning sleeve 522 and the buffering effect of spring 523 enable the limiting rod 52 to adapt to the offset of the pipe pile. The buffering effect of spring 523 and the sliding fit of positioning rod 521 and positioning sleeve 522 can prevent the limiting rod 52 from causing rigid damage to the pipe pile, thereby enabling more flexible limiting of the pipe pile.

[0042] Reference Figure 1 and Figure 3 Specifically, the limiting ring 51 is equipped with several rollers 60, which can rotate on the limiting ring 51. The rollers 60 are generally rubber or plastic wheels. The rollers 60 reduce the friction between the pipe pile and the limiting ring 51, allowing the pipe pile to pass through the limiting ring 51 more smoothly during the pile driving process.

[0043] The implementation principle of the verticality control device for pipe pile driving according to an embodiment of this application is as follows: Through the coordinated action of multiple components such as the limiting frame 11, the installation component 30, the adjustment component 40, and the limiting component 50, the verticality of the pipe pile during the driving process can be controlled in real time and accurately. The limiting frame 11 and the limiting component 50 can limit the pipe pile in the horizontal direction, the installation component 30 connects the crane to the pipe pile, and the adjustment component 40 can precisely adjust the verticality of the pipe pile. Compared with traditional verticality control methods, this device is not affected by the experience and subjective judgment of construction personnel, and can respond promptly and effectively to dynamic deviations of the pipe pile during the driving process, thus improving the accuracy and reliability of pipe pile verticality control. The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
