Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, and in particular relates to a drilling and piling machine with a straightening function. Background Technology

[0002] To improve the bearing capacity of the foundation, pile foundation engineering is often involved in building, bridge, or municipal engineering projects. Piling machines are used to drive piles into the foundation. Many pile drivers are now equipped with drilling mechanisms to form pile holes. However, because the working sites are usually muddy ground, pile drivers struggle to achieve sufficient stability, causing slight deviations in the drill rod during drilling, affecting the verticality of the pile hole and the quality of pile driving. Manual adjustments are time-consuming and labor-intensive, failing to meet the efficiency and precision requirements of modern engineering construction. Furthermore, the drilling mechanisms on current pile drivers generally only allow for drilling of fixed sizes. When different hole diameters are required, the drilling mechanism must be changed. Frequent changes to the drilling mechanism not only increase the complexity and time cost of construction but also increase the workload of construction workers, significantly reducing the overall efficiency of the project.

[0025] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0026] This utility model proposes a drilling and piling machine with a straightening function, which solves the problem of slight deviation of the drill rod due to the instability of the soil surface at the pile foundation operation site during drilling operations. It can conveniently and effectively adjust the verticality of the drill rod to ensure the verticality of the pile hole and the quality of pile driving. In addition, the drilling and piling machine proposed in this application can also perform drilling and hole enlargement operations for pile holes of different diameters as needed without replacing the drill rod, reducing labor intensity and improving the overall efficiency of drilling operations.

[0027] like Figures 1-3As shown, this application proposes a drilling pile driver with a straightening function. It includes a base body 1, a rotating top seat 2, and a fixing mechanism 26. The base body 1 is rotatably connected to a drilling mechanism, which can form pile holes on the ground to meet the subsequent pile driving requirements. The rotating top seat 2 is rotatably connected to the top of the base body 1 and can rotate relative to the base body 1. The rotating top seat 2 is provided with an extension arm extending outward from the base body 1 and a counterweight lateral movement mechanism. The counterweight lateral movement mechanism is connected to a counterweight block 7 and can drive the counterweight block 7 to move along the extension arm to adjust the verticality of the base body 1. The fixing mechanism 26 is the supporting foundation of the base body 1, which is set at the bottom of the base body 1 and is used to fix the base body 1 to the ground.

[0028] The aforementioned technical solution addresses the problem of drilling mechanism misalignment caused by insufficient flatness and bearing capacity of the soil surface at the pile foundation work site. Its working principle is as follows: Before drilling begins, by analyzing the direction and angle of the drilling mechanism's misalignment, the rotating top seat 2 is rotated, adjusting the direction of the counterweight 7 relative to the machine base 1. Then, the counterweight lateral movement mechanism adjusts the counterweight 7 to move closer to or further away from the machine base 1, similar to using a lever principle to adjust the posture of the machine base 1, thereby straightening it and ultimately ensuring the drilling mechanism is in a vertical position. This allows for drilling operations to form vertical pile holes on the ground, ensuring the verticality of the pile holes and the quality of pile driving. The drilling and pile driving machine proposed in this application has a simple overall structure, is easy to use, has a wide adjustment range and high adjustment precision, and possesses excellent practicality.

[0029] The specific dimensions and shape of the base body 1 in this application are not limited here; preferably, the cross-section of the base body 1 is set to be circular, the main body of the rotating top seat 2 is the same in shape and size as the base body 1 and aligned, and the extended arm is set along the radial direction of the base body 1 so as to adjust the position of the counterweight 7 according to the angle of deviation and improve the adjustment efficiency.

[0030] In one specific embodiment, the base body 1 is provided with a first rotating mechanism for driving the rotating top seat 2 to rotate axially. The first rotating mechanism includes a first driving member 13 and a first rotating shaft 9 located at the driving end of the first driving member 13. The first rotating shaft 9 extends out of the top of the base body 1 and is connected to the bottom of the rotating top seat 2. By running the first driving member 13, the first rotating shaft 9 can be driven to rotate, thereby causing the rotating top seat 2 and the counterweight 7 to rotate, so as to adjust the direction of the counterweight 7 relative to the base body 1.

[0031] Furthermore, the aforementioned base body 1 has a first internal groove 8 inside, and a first rotating mechanism is disposed within the first internal groove 8, wherein a first rotating shaft 9 is rotatably connected to the first internal groove 8 in a vertical direction; preferably, the top end of the first rotating shaft 9 is connected to the center position of the rotating top seat 2, and the bottom end is connected to the first driving member 13; the first driving member 13 in this application can be a servo motor, hydraulic motor, or pneumatic motor, etc., and is not limited here, as long as it can drive the first rotating shaft 9 to rotate axially. By setting the first rotating mechanism, the rotating top seat 2 can be rotated axially, which facilitates the adjustment of the position of the counterweight 7.

[0032] The aforementioned counterweight lateral movement mechanism includes a first sliding actuator 6. The output end of the first sliding actuator 6 is connected to a first lead screw 4. The first lead screw 4 is arranged along the length direction of the extended arm and is threadedly connected to a first slider 5. The bottom of the first slider 5 is connected to a counterweight 7. By operating the first sliding actuator 6, the first lead screw 4 can be driven to rotate, thereby causing the first slider 5 and the counterweight 7 to move along the length direction of the extended arm, so that the counterweight 7 moves closer to or further away from the machine base body 1.

[0033] The first sliding actuator 6 in this application can be located in the main body of the rotating top seat 2 or at one end of the extended arm, without limitation. In a specific embodiment, the first sliding actuator 6 is located in the main body of the rotating top seat 2 near the end of the extended arm. The bottom of the extended arm is provided with a first sliding groove 3. The first lead screw 4 is rotatably connected in the first sliding groove 3, and one end of it is connected to the first sliding actuator 6. The counterweight 7 is connected to the bottom of the first slider 5. By running the first sliding actuator 6, the first slider 5 can drive the counterweight 7 to slide in the first sliding groove 3, which cooperates with the rotation of the rotating top seat 2 to adjust the relative position of the counterweight 7 with respect to the machine base body 1, and finally completes the straightening of the machine base body 1, so that the drilling mechanism is in a vertical state.

[0034] The aforementioned base body 1 is also provided with a second rotating mechanism for driving the drilling mechanism to rotate. The second rotating mechanism includes a second driving member 19 and a second rotating shaft 15 located at the driving end of the second driving member 19. The second rotating shaft 15 is connected to the drilling mechanism. When the drilling mechanism is in a vertical state, the second driving member 19 is operated, thereby driving the second rotating shaft 15 to rotate, which in turn drives the drilling mechanism to rotate, and finally completes the drilling operation.

[0035] Specifically, the base body 1 in this application also has a second internal groove 14 inside, and a third rotating shaft is rotatably connected to the inside of the second internal groove 14 in the vertical direction. Its top end is connected to the second driving member 19, and its bottom end is connected to the drilling mechanism. The second driving member 19 in this application can be a servo motor, hydraulic motor, or pneumatic motor, etc., and there is no limitation, as long as it can drive the second rotating shaft 15 to rotate axially. By setting the second transmission mechanism, the drilling mechanism can be rotated.

[0036] The aforementioned drilling mechanism includes a drill rod 24 lateral movement assembly and a drill rod 24 connected to the drive end of the drill rod 24 lateral movement assembly. The drill rod 24 lateral movement assembly is connected to a second rotating shaft and drives the drill rod 24 mechanism to move laterally. Normally, the drilling mechanism performs drilling operations by rotating the drill rod 24. When the axis of the drill rod 24 coincides with the axis of the second rotating shaft 15, the borehole rotates axially, forming a pile hole with the same outer diameter as the drill rod 24. When the axis of the drill rod 24 does not coincide with the axis of the second rotating shaft 15, the drill rod 24 rotates eccentrically relative to the second rotating shaft 15, thereby forming a rotation range greater than its own radius. By setting up a drill rod 24 lateral movement component, the position of the drill rod 24 relative to the second rotating shaft 15 can be adjusted, enabling hole enlargement operations or forming pile holes larger than the size of the drill rod 24 without replacing the drill rod 24. This meets the drilling operation requirements under different working conditions, especially for situations where there are multiple specifications of piles on the same foundation. It avoids the operational difficulties and labor intensity caused by replacing the drill rod 24, significantly improving construction efficiency.

[0037] Furthermore, the drill rod 24 lateral movement assembly includes a turntable 25, the top of which is connected to the bottom end of the second rotating shaft 15. A second sliding actuator 23 is provided at one end of the bottom of the turntable 25. The output end of the second sliding actuator 23 is connected to a second lead screw 21, which extends radially along the second rotating shaft 15 and is threadedly connected to a second slider 22. The bottom of the second slider 22 is connected to the drill rod 24. The turntable 25 can rotate axially under the drive of the second rotating shaft 15, thereby further driving the drill rod 24 to rotate. Simultaneously, the drill rod 24 can move along the axial direction of the second rotating shaft 15 under the drive of the second slider 22. When the axis of the drill rod 24 does not coincide with the axis of the second rotating shaft 15, the drill rod 24 rotates eccentrically relative to the second rotating shaft 15 to achieve hole enlargement or to form a pile hole larger than the size of the drill rod 24.

[0038] Specifically, the bottom of the turntable 25 is provided with a second slide groove 20, which is arranged radially along the second rotating shaft 15. A second lead screw 21 is rotatably provided inside the slide groove 20. One end of the second lead screw 21 is connected to a second sliding driver 23 and threadedly connected to a second slider 22. By running the second sliding driver 23, the second slider 22 can be driven to slide in the second slide groove 20, thereby adjusting the position of the drill rod 24 connected to the second slider 22.

[0039] In a preferred embodiment, the second rotating shaft 15 is aligned with the axis of the base body 1. By aligning the axis of the second rotating shaft 15 with the axis of the base body 1, the stability of the base body 1 can be maximized during drilling operations, and it is also easier for operators to adjust the position of the drill rod 24 with the axis of the base body 1 as a reference.

[0040] Preferably, the first driving component and / or the second driving component adopt worm gear meshing transmission. By adopting worm gear meshing transmission, not only is the structure simple and easy to manufacture, but it also has the characteristics of large transmission ratio, smooth transmission, low noise and good self-locking performance. In one specific embodiment, the first driving member 13 is disposed on one side of the axis of the base body 1, and its driving end is the first driving shaft 11. The first driving shaft 11 is connected to the first worm 12, which is arranged in a direction perpendicular to the first rotating shaft 9 and meshes with the first worm wheel 10 outside the first rotating shaft 9. In another specific embodiment, the second driving member 19 is disposed on one side of the axis of the base body 1, and its driving end is the second driving shaft 17. The second driving shaft 17 is connected to the second worm 18, which is arranged in a direction perpendicular to the second rotating shaft 15 and meshes with the second worm wheel 16 outside the second rotating shaft 15. In this application, the positions of the first driving member 13 and the second driving member 19 can be arranged in different parts of the base body 1 as needed, as long as the technical effect of driving the first rotating shaft 9 and the second rotating shaft 15 to rotate can be achieved respectively.

[0041] In one specific embodiment, the first driving member 13 and the second driving member 19 are arranged in parallel vertically, the first worm 12 is parallel to the second worm 18, and the axes of the first rotating shaft 9 and the second rotating shaft 15 are aligned with the axis of the base body 1, so as to make full use of the internal space of the base body 1 and reduce the overall volume of the base body 1.

[0042] Furthermore, the fixing mechanism 26 in this application is evenly distributed and includes a positioning cone rod and a positioning drive for adjusting the length of the positioning cone rod. Specifically, the bottom end of the positioning cone rod is pointed and can extend into the ground under the gravity of the entire device, and will not easily move. In addition, by setting the positioning drive, the length of the positioning cone rod can be adjusted, thereby making preliminary adjustments to the verticality of the machine base body 1 and the drill rod 24 before the start of operation, so as to further make precise adjustments to the verticality of the drill rod 24 by rotating the top seat 2 and the counterweight moving mechanism.

[0043] In a preferred embodiment, the base body 1 of this application is further provided with an observation window, which is used by construction personnel to observe the position, movement and verticality of the drill rod mechanism at any time; the observation window is located at a position corresponding to the top of the drill rod mechanism.

[0044] This application also proposes a method for using a drilling pile driver with a straightening function, including the following steps:

[0045] When the drill rod 24 deviates, the first drive member 13 and the first sliding drive are activated until the drill rod 24 is in a vertical state. Specifically, the first drive member 13 is activated to drive the first rotating shaft 9 to rotate, which in turn causes the rotating top seat 2 to rotate and drives the extension arm and counterweight 7 to move to the required angle. Then the first sliding drive is activated to move the counterweight 7 towards or away from the machine base body 1 until the drill rod 24 is in a vertical state, and drilling operations can then be carried out.

[0046] When the radius of the pile hole is greater than the radius of the drill rod 24, the second sliding actuator 23 is operated until the distance between the end of the drill rod 24 away from the axis of the second rotating shaft 15 and the axis of the second rotating shaft 15 is equal to the radius of the pile hole. In actual use, when the radius of the pile hole is greater than the radius of the drill rod 24, it is necessary to first drill a foundation hole with the axis of the drill rod 24 aligned with the second rotating shaft 15, and then enlarge the foundation hole to form a pile hole that meets the requirements. Specifically, the second sliding actuator 23 is operated to move the second slider 22 and the drill rod 24 to the required position, and the second driving component 19 is started again to rotate the second rotating shaft 15, thereby causing the drill rod 24 to rotate eccentrically relative to the second rotating shaft 15 to form a pile hole.

[0047] Through the above-mentioned technical description, this application solves the problem of drilling mechanism tilting caused by insufficient flatness and bearing capacity of the muddy ground at the pile foundation operation site. By cooperating with the first rotating mechanism and the counterweight lateral movement mechanism, the relative position of the counterweight block and the machine base body is adjusted, thereby straightening the machine base body and ultimately making the drilling mechanism vertical, forming a vertical pile hole on the ground, ensuring the verticality of the pile hole and the quality of pile driving.

[0048] This application, by setting up a drill rod lateral movement component, can adjust the position of the drill rod relative to the second rotation axis, enabling hole enlargement operations or the formation of pile holes larger than the drill rod size without replacing the drill rod. This meets the drilling operation requirements under different working conditions, avoids the operational difficulties and labor intensity caused by replacing the drill rod, and significantly improves construction efficiency.

[0049] The drilling and piling machine proposed in this application has a simple overall structure, is easy to use, and has a wide adjustment range and high adjustment accuracy, making it highly practical.

[0050] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
