Description

Technical Field

[0001] This utility model relates to the technical field of pile diameter control devices, specifically to a pile diameter control device for cement-soil compaction pile construction. Background Technology

[0002] The compaction method is an effective way to reinforce foundations above the groundwater level. In recent years, the compaction method has been widely used. A compaction pile is formed by pressing or driving a steel pipe with a plug, valve or cone into the soil to form a hole and compact the soil layer. Then, filler such as lime, soil and sand is put into the hole to form a pile. In existing technologies, pile driving machines are typically used to drill holes at the desired locations. The diameter of the pile pipe is the same as the designed pile diameter. By driving a steel pipe with the same diameter as the pile hole into the soil and then pulling the pipe out to form the hole, the pile diameter can be directly controlled. Replacing the pile pipe is a common operation in pile driving construction to adapt to different engineering needs. The pile diameter of the compaction pile can be adjusted as needed. However, the pile diameter often deviates due to equipment shaking or insufficient verticality. For example, an inclined pile hole may cause the local diameter to be too large or too small. Utility Model Content

[0003] This utility model proposes a pile diameter control device for cement-soil compaction pile construction, which solves the problem in the prior art that the pile diameter often deviates due to equipment shaking and insufficient verticality, and that tilted pile holes may cause local diameters to be too large or too small.

[0004] The technical solution of this utility model is as follows: A pile diameter control device for cement-soil compaction pile construction includes a pile driving machine and a pile pipe. The pile driving machine includes a base, and a lifting mechanism is provided on the base. The pile pipe can be lifted and lowered on one side of the base through the lifting mechanism. The lifting mechanism includes a lifting head, a connecting plate, a fixed seat, and a clamping mechanism. One end of the connecting plate is fixedly connected to one end of the lifting head. The fixed seat is rotatably disposed below the connecting plate through an adjustment mechanism. A placement groove is provided on the fixed seat for accommodating one end of the pile pipe. The clamping mechanism is disposed on the fixed seat for clamping and fixing the pile pipe.

[0005] Preferably, the adjustment mechanism includes a fixed plate, a first rotating shaft, and a first driving member. The fixed plate is fixedly connected to both ends of the connecting plate. The first rotating shaft is rotatably connected to one end of the fixed plate. The two first rotating shafts are rotatably connected to both ends of the fixed seat. The first driving member is disposed on the connecting plate and the fixed seat and is used to drive the fixed seat to rotate and fix around the axis of the first rotating shaft.

[0006] Furthermore, the first driving component includes a hydraulic cylinder, an abutment seat, a second rotating shaft, an abutment plate, a force-bearing plate, and a limiting ring. The hydraulic cylinder is mounted on the connecting plate, and the output end of the hydraulic cylinder passes through the connecting plate and extends therefrom. One end of the abutment seat is fixedly connected to the output end of the hydraulic cylinder. A slot is provided on the abutment seat, and the second rotating shaft is rotatably disposed in the slot. One end of the abutment plate is rotatably connected to the second rotating shaft. One end of the force-bearing plate is fixedly connected to one end of the fixed seat. A through slot is provided on the force-bearing plate, and the other end of the abutment plate is located in the through slot. The limiting ring is fitted onto the other end of the abutment plate and is fixedly connected to the abutment plate.

[0007] Furthermore, the clamping mechanism includes a movable plate, an extension plate, and a clamping plate. Two movable slots are symmetrically opened in the fixed base. The movable plate is slidably disposed in the movable slot through a second driving member. One end of the extension plate is fixedly connected to one end of the movable plate, and one end of the clamping plate is fixedly connected to the other end of the extension plate.

[0008] As a further embodiment of this application, the second driving component includes a threaded rod, a connecting shaft, and a driving motor. The threaded rod is rotatably disposed within the moving groove. The two threaded rods are respectively threaded into the two moving plates. The two ends of the connecting shaft are respectively coaxially and fixedly connected to one end of the two threaded rods. The driving motor is mounted on the fixed base, and the output end of the driving motor is coaxially and fixedly connected to one end of one of the threaded rods.

[0009] As a further embodiment of this application, the force-bearing plate is provided with a snap-fit ​​groove that cooperates with the limiting ring, and the snap-fit ​​groove and the through groove are connected.

[0010] The beneficial effects of this utility model are as follows: In this utility model, by setting a clamping mechanism, one end of the pile tube is placed in the placement groove. By starting the drive motor, the two clamping plates move towards each other to clamp and fix one end of the pile tube in the placement groove. This can adapt to pile tubes of different diameters and clamp the pile tube stably. In this invention, the tilt sensor and hydraulic cylinder are activated through the cooperation of a connecting plate, a fixed base, a tilt sensor, and an adjustment mechanism. The output end of the hydraulic cylinder "supports" the fixed base. When the tilt sensor detects that the fixed base is tilted, the tilt sensor data is transmitted to the controller in real time. The controller then transmits a signal to the hydraulic cylinder, which drives the force plate to rotate the fixed base around the axis of the first rotating shaft. Once the fixed base is level, the output end of the hydraulic cylinder stops driving and continues to hold the abutment plate against the force plate. This facilitates the adjustment of the tilt angle of the pile pipe, maintains the horizontal state of the pile pipe, and allows the pile pipe to move vertically downwards under the drive of the lifting mechanism for drilling. This avoids insufficient verticality of the pile pipe, which could lead to deviations in the pile diameter. Tilted pile holes can cause local diameters to be too large or too small.

[0014] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0015] like Figures 1-5 As shown, this embodiment proposes a pile diameter control device for cement-soil compaction pile construction, including a pile driving machine 1 and a pile pipe 2. The pile driving machine 1 includes a base 3, and a lifting mechanism 4 is provided on the base 3. The pile pipe 2 can be lifted and lowered on one side of the base 3 through the lifting mechanism 4. The lifting mechanism 4 includes a lifting head 5, a connecting plate 6, a fixed seat 7, and a clamping mechanism. like Figure 2 , Figure 3 and Figure 4 As shown, one end of the connecting plate 6 is fixedly connected to one end of the lifting head 5. A placement groove 8 is provided on the fixed base 7 to accommodate one end of the pile pipe 2. The fixed base 7 is rotatably positioned below the connecting plate 6 via an adjustment mechanism. It should be noted that an angle sensor 23 is installed on the fixed base 7. The adjustment mechanism includes a fixed plate 9, a first rotating shaft 10, and a first driving component. Fixed plates 9 are fixedly connected to both ends of the connecting plate 6. A first rotating shaft 10 is rotatably connected to one end of each fixed plate 9. The two first rotating shafts 10 are rotatably connected to both ends of the fixed base 7, respectively. The first driving component is located on the connecting plate 6 and the fixed base 7, and is used to drive the fixed base 7 to rotate and fix around the axis of the first rotating shaft 10. The first driving component includes a hydraulic cylinder 11, an abutment seat 12, a second rotating shaft 13, and an abutment... Plate 14, force plate 15 and limiting ring 16, hydraulic cylinder 11 is installed on connecting plate 6, hydraulic cylinder 11 is equipped with controller matching tilt sensor 23, output end of hydraulic cylinder 11 passes through connecting plate 6 and extends, one end of abutment seat 12 is fixedly connected to output end of hydraulic cylinder 11, a slot is opened on abutment seat 12, second rotating shaft 13 is rotatably set in the slot, one end of abutment plate 14 is rotatably connected to second rotating shaft 13, one end of force plate 15 is fixedly connected to one end of fixed seat 7, through slot is opened on force plate 15, the other end of abutment plate 14 is in through slot, limiting ring 16 is fitted on the other end of abutment plate 14 and fixedly connected to abutment plate 14, a snap-fit ​​groove is opened in force plate 15 to cooperate with limiting ring 16, snap-fit ​​groove and through slot are connected; Specifically, by activating the tilt sensor 23 and the hydraulic cylinder 11, the output end of the hydraulic cylinder 11 "supports" the fixed seat 7. When the tilt sensor 23 detects that the fixed seat 7 is tilted, the data of the tilt sensor 23 is transmitted to the controller in real time. The controller transmits a signal to the hydraulic cylinder 11, which drives the fixed seat 7 to maintain balance. The output end of the hydraulic cylinder 11 pushes the abutment seat 12 to move longitudinally. The abutment seat 12 drives the abutment plate 14 to move longitudinally. The abutment plate 14 is locked in the locking groove by the limiting ring 16. At this time, the other end of the abutment plate 14 is fixedly connected to the force plate 15. The abutment plate 14 pushes the force plate 15 to move longitudinally. The force plate 15 drives the fixed seat 7 to rotate around the axis of the first rotating shaft 10. The rotation of the fixed seat 7 drives one end of the abutment plate 14 to rotate under the support of the second rotating shaft 13 (the angle is offset). When the fixed seat 7 is adjusted to be horizontal, the output end of the hydraulic cylinder 11 stops driving and continues to make the abutment plate 14 press against the force plate 15. It should be added that the hydraulic cylinder 11 is a high-strength hydraulic cylinder 11, which can maintain the stability of the fixed seat 7; like Figure 2 As shown, the clamping mechanism is mounted on the fixed base 7 and is used to clamp the fixed pile pipe 2. The clamping mechanism includes a movable plate 17, an extension plate 18, and a clamping plate 19. Two movable slots are symmetrically opened in the fixed base 7. The movable plate 17 is slidably arranged in the movable slots through a second driving member. One end of the extension plate 18 is fixedly connected to one end of the movable plate 17, and one end of the clamping plate 19 is fixedly connected to the other end of the extension plate 18. The other end of the clamping plate 19 is arc-shaped and has an anti-slip layer. The second driving member includes a threaded rod 20, a connecting shaft 21, and a drive motor 22. The threaded rod 20 is rotatably arranged in the movable slot. The two threaded rods 20 are threadedly engaged with the two movable plates 17 respectively, and the threads of the two threaded rods 20 have opposite directions of rotation. Both ends of the connecting shaft 21 are coaxially and fixedly connected to one end of each of the two threaded rods 20. The drive motor 22 is mounted on the fixed base 7. The output end of the drive motor 22 is coaxially and fixedly connected to one end of a threaded rod 20. By starting the drive motor 22, the output end of the drive motor 22 rotates, which drives one threaded rod 20 to rotate. This threaded rod 20 drives the connecting shaft 21 to rotate, and the connecting shaft 21 drives the other threaded rod 20 to rotate. In this way, the two threaded rods 20 rotate simultaneously. The two threaded rods 20 drive the two moving plates 17 to move towards each other. The moving plates 17 drive the extension plate 18 to move, and the extension plate 18 drives the clamping plate 19 to move. By the two clamping plates 19 moving towards each other, one end of the pile tube 2 in the placement groove 8 is clamped and fixed. It should be added that the drive motor 22 is a power-off braking motor. After the two clamping plates 19 clamp and fix the pile tube 2, the output end of the drive motor 22 can continue to maintain a stable clamping of the pile tube 2 after the drive motor 22 is turned off. Working Principle: When installing and adjusting the level of the pile pipe 2, the pile diameter control device for cement-soil compaction pile construction places one end of the pile pipe 2 in the placement groove 8. The drive motor 22 is started, and its output rotates, driving a threaded rod 20 to rotate. This threaded rod 20 drives the connecting shaft 21 to rotate, which in turn drives another threaded rod 20. This simultaneous rotation of the two threaded rods 20 causes two moving plates 17 to move towards each other. The moving plates 17 then move the extension plate 18, which in turn moves the clamping plate 19. The two clamping plates 19 clamp and fix one end of the pile pipe 2 in the placement groove 8. The tilt sensor 23 and hydraulic cylinder 11 are then activated. The output of the hydraulic cylinder 11 "supports" the fixed base 7. When the tilt sensor 23 detects a tilt in the fixed base 7, its data is transmitted to the controller in real time. The controller then transmits a signal to the hydraulic cylinder 11, which then... The hydraulic cylinder 11 drives the fixed seat 7 to maintain balance and pushes the abutment seat 12 to move longitudinally through the output end of the hydraulic cylinder 11. The abutment seat 12 drives the abutment plate 14 to move longitudinally. The abutment plate 14 is locked in the locking groove by the limiting ring 16. At this time, the other end of the abutment plate 14 is fixedly connected to the force plate 15. The abutment plate 14 pushes the force plate 15 to move longitudinally. The force plate 15 drives the fixed seat 7 to rotate around the axis of the first rotating shaft 10. The rotation of the fixed seat 7 drives one end of the abutment plate 14 to rotate under the support of the second rotating shaft 13 (the angle is offset). When the fixed seat 7 is adjusted to be horizontal, the output end of the hydraulic cylinder 11 stops driving and continues to make the abutment plate 14 press against the force plate 15. This makes it easy to adjust the tilt angle of the pile pipe 2, keep the pile pipe 2 in a horizontal state, and allow the pile pipe 2 to move vertically downward under the drive of the lifting mechanism 4 to drill holes. This avoids the pile pipe 2 from being too vertical and causing the pile diameter to deviate. The tilted pile hole will cause the local diameter to be too large or too small.

[0016] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
