[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a triple-tube high-pressure jet grouting pile driver with active traction tunneling, including a pile driver body 1. A vertical frame 2 is rotatably mounted on the front end of the pile driver body 1 via a hinge seat 4. A diagonal hydraulic rod 3 is hinged between the vertical frame 2 and the pile driver body 1. The tilt of the vertical frame 2 can be controlled by the extension and retraction of the diagonal hydraulic rod 3, thereby controlling the tunneling angle of the drill rod 11. A slide rail 5 is fixedly mounted on the front side of the vertical frame 2 along the height direction. A lifting mounting frame 6 is provided on the front side of the slide rail 5. The back of the lifting mounting frame 6 is slidably mounted on the slide rail 5 via two sets of sliders 7. A slide rod 8 is fixedly mounted in the inner cavity of the lifting mounting frame 6. Two sets of slide seats 9 are slidably mounted on the slide rod 8. A top drive device 10 is fixedly mounted on the front side of the slide seats 9. The drill rod 11 is mounted on the bottom of the top drive device 10.

[0022] Specifically, a buffer spring 12 is sleeved on the outer wall of the slide rod 8, and the upper and lower ends of the buffer spring 12 abut against the slide seat 9 and the top of the inner cavity of the lifting mounting frame 6. A limit sensor 13 is also provided on the top of the inner cavity of the lifting mounting frame 6. The limit sensor 13 is connected to an external controller, and the controller can control the start and stop speed and torque of the drive motor 17.

[0023] Furthermore, a pair of fixed pulleys 14 are fixedly installed at the upper and lower ends of the upright frame 2, and a high-strength transmission belt 15 is tensioned between the four fixed pulleys 14. The lifting mounting frame 6 is fixedly connected to the high-strength transmission belt 15 and can move up and down with the movement of the high-strength transmission belt 15.

[0024] Furthermore, a transmission belt drive device is also provided on the back of the upright frame 2. The transmission belt drive device includes a drive mounting base 16, and a drive motor 17 is mounted on the back of the drive mounting base 16. The output end of the drive motor 17 is connected to a transmission wheel 18. A drive wheel 19 is engaged on one side of the transmission wheel 18, and the drive wheel 19 is engaged with the high-strength transmission belt 15. After the drive motor 17 is started, the high-strength transmission belt 15 can be driven to move through the sequential transmission of the transmission wheel 18 and the drive wheel 19, thereby driving the lifting mounting frame 6 to move up and down.

[0025] It is worth noting that, in order to adjust the tension of the transmission belt during equipment installation, two sets of screws 20 are fixedly installed on the back of the upright 2 corresponding to the position of the drive mounting seat 16. The screws 20 pass through the mounting holes on the drive mounting seat 16 and are positioned by two sets of double nuts 21. By adjusting the distance between the drive mounting seat 16 and the back of the upright 2, the tension of the high-strength transmission belt 15 can be controlled.

[0026] It is worth noting that the lifting mounting bracket 6 has a C-shaped structure with the opening facing forward.

[0027] The diagonal hydraulic rod 3, limit sensor 13, and drive motor 17 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, rear, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0028] Working principle: During use, when the drill rod 11 descends without significant resistance, the speed of the drive motor 17 can be appropriately increased to improve tunneling efficiency. When the drill rod 11 encounters a relatively hard pebble area, due to the increased resistance, the top drive device 10 overcomes the elastic force of the buffer spring 12 and moves upward relative to the lifting mounting frame 6 until the limit sensor 13 detects the approach signal of the top drive device 10 and feeds the detection signal back to the controller. The controller then controls the drive motor 17 to decelerate, reducing the feed speed, thereby reducing the tunneling resistance of the drill bit and preventing the drill bit from jamming or breaking the tooth structure. After the drill bit passes through the hard pebble area, due to the reduced resistance, under the restoring elastic force of the buffer spring 12, the limit sensor 13 detects that the top drive device 10 has moved away. At this time, the drive motor 17 is controlled to speed up again to improve tunneling efficiency.
