Therefore, they cannot be understood as a limitation on the present invention.

[0032] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0033] like Figure 1As shown, the present invention discloses a pile driver with a stable support function, comprising a pile driver body 1, with a movable crawler 2 disposed at the bottom end thereof. The pile driver body 1 has the same structure as existing pile drivers, with the upper portion of the pile driver body 1 being able to rotate on the lower portion with the crawler 2, thereby facilitating adjustment of the pile driving position. A piling mechanism for piling and a driver control cabin 3 for controlling the piling mechanism are disposed at one end of the pile driver body 1. The driver control cabin 3 allows the piling mechanism to be operated for piling work, and the pile driver to be driven for movement.

[0034] like Figure 1 、 Figure 6 As shown, the piling mechanism includes a pile frame 23, which is rotatably connected to the pile driver body 1. A hydraulic cylinder 1 24 is mounted on the pile driver body 1. The bottom end of the hydraulic cylinder 1 24 is rotatably connected to the pile driver body 1, and the hydraulic rod of the hydraulic cylinder 25 is rotatably connected to the frame. A hydraulic cylinder 25 25 is mounted at the top of the pile frame 23. The hydraulic cylinder of the hydraulic cylinder 25 is connected to a lifting base 26 that is slidably mounted on the pile frame 23. A motor base 27 is mounted on the lifting base 26, which is equipped with a motor 28. The output end of the motor 28 is connected to a drill rod 29. A drill bit 30 is mounted at the bottom end of the drill rod 29. A protective cover 31 is provided at the bottom end of the pile frame 23 to protect the drill bit 30. During operation, the hydraulic rod of the hydraulic cylinder 24 extends forward, driving the pile frame 23 to rotate on the pile driver body 1 and shift it to a vertical position. Then the hydraulic cylinder 25 drives the lifting seat 26 to descend, and then drives the drill rod 29 to descend. At the same time, the motor 28 drives the drill rod 29 to rotate, and the drill bit 30 rotates while descending to drill and perform the piling work.

[0035] The other end of the pile driver body 1 is equipped with a hydraulic motor-type sediment extraction mechanism. This mechanism includes a hydraulic motor 4, which is connected to the sediment extraction structure, which in turn is connected to a sediment collection tank 7. The sediment extraction structure includes a centrifugal pump 6, which is equipped with a flanged inlet pipe 8. This inlet pipe 8 is connected to a pipeline through which the sediment generated by pile driving is extracted. The centrifugal pump 6 is connected to the sediment collection tank 7 via an extraction pipe. The sediment collection tank 7 is mounted on the pile driver body 1. The hydraulic motor 4 is connected to the centrifugal pump 6 via a speed reducer 5. The hydraulic motor 4 is an actuator in the hydraulic system, converting the fluid pressure energy provided by the hydraulic pump into mechanical energy on its output shaft. The fluid is the medium that transmits force and motion. The hydraulic motor 4 has high torque and occupies a small space. Using the hydraulic motor 4 instead of an electric motor to power sediment extraction not only provides greater power but also saves energy. The hydraulic motor 4 provides power, and the centrifugal pump 6 draws the silt into the silt collection box 7, avoiding the trouble of secondary cleaning after the silt is discharged everywhere. The silt collection box 7 is fixedly set on the pile driver body 1 and is provided with a discharge port, and a sealing cover is provided at the discharge port. A detachable counterweight block 9 is provided on the silt collection box 7, and the counterweight block 9 is connected to the silt collection box 7 by bolts. Because the pile driving mechanism is arranged at the front end of the pile driver body 1, and the silt collection box 7 is arranged at the rear end of the pile driver body 1, the pile driving mechanism itself is heavy, and the counterweight block 9 can balance the mass of the pile driving mechanism, thereby improving the stability of the overall device.

[0036] like Figure 2 、 Figure 3 、 Figure 4 As shown, support mechanisms for stable support are symmetrically arranged on both sides of the pile driver body 1. The support mechanism includes a fixed base 10, which is arranged on the side of the pile driver body 1. A telescopic cylinder 11 is mounted on the fixed base 10. The telescopic rod of the telescopic cylinder 11 extends through the fixed base 10 and is connected to the support structure. The support structure includes a connecting base 12. The top of the connecting base 12 is connected to the telescopic rod of the telescopic cylinder 11. The four corners of the bottom of the connecting base 12 are connected to the support base 13 via sliding assemblies. The sliding assembly includes a sliding column 14 and a sliding base 15. The sliding base 15 is provided with a slide groove 16 that matches the sliding column 14. The sliding column 14 is inserted into the slide groove 16 and slidably connected to the slide groove 16. The bottom end of the sliding base 15 is connected to the top of the support base 13, and the top end of the sliding column 14 is connected to the bottom end of the connecting base 12. The bottom end of the connecting base 12 is connected to the top of the support base 13 via a damper 17. The telescopic cylinder 11 is a hydraulic cylinder. The extension of the telescopic rod of the telescopic cylinder 11 drives the support structure to descend, thereby playing a supporting role. The damper 17 has a shock-absorbing effect, thereby improving the support stability.

[0037] like Figure 3 、 Figure 5As shown, a mounting plate 18 is provided at the bottom end of the support base 13. Sliders 19 are provided on both sides of the support base 13. Sliding grooves 20 are provided on the mounting plate 18 to match the slides 19. The slides 19 of the support base 13 are inserted into the sliding grooves 20, and the mounting plate 18 and the support base 13 are slidably connected. Limiting blocks 21 are provided in the sliding grooves 20 of the mounting plate 18 to limit the sliding movement of the slides 19. Several fixing cones 22 are provided at the bottom end of the mounting plate 18 for fixing.

[0038] During use, the slider 19 is aligned with the sliding slot 20, and the mounting plate 18 is pushed so that the mounting plate 18 is installed at the bottom end of the support base 13. Then, the telescopic cylinder 11 drives the connecting base 12 downward, and the connecting base 12 drives the supporting base 13 downward, so that the fixing cone 22 is inserted into the ground. During the piling operation, the vibration generated by the pile driver body 1 causes the connecting base 12 to move downward and squeeze the supporting base 13. The sliding column 14 slides within the sliding base 15, and the damper 17 acts as a shock absorber, reducing the amplitude and improving the support stability.

[0039] Therefore, the present invention adopts a pile driver with a stable support function of the above structure, which is lowered to the ground through the support mechanism on the side of the pile driver body to provide support force for the pile driver as a whole, and is fixed to the ground using the mounting plate 18 with a fixing cone 22, thereby improving the overall stability of the pile driver during the working process and reducing the impact of vibration generated during the working process of the pile driver on the piling work.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
