[0023] According to one aspect of this application, embodiments of this application provide a multi-mode mixing pile machine function conversion system, please refer to the following: Figs. 1 to 4The multi-mode mixing pile machine function conversion system includes the original single-shaft mixing pile machine's power head 1000, frame, walking system, operator's cab, guide frame, detachable power expansion module 2000, extended mixing drill rod 3000, adjustable multi-hole guide frame 4000, and multi-functional drill bit connecting beam 5000. The detachable power expansion module 2000 can be selectively installed on one or more sides of the original single-shaft mixing pile machine's power head 1000 via a quick-connect structure. The extended mixing drill rod 3000... The two output shafts of the detachable power expansion module 2000 are connected via a coupling and arranged parallel to the original single-axis mixing drill rod to form a multi-axis mixing drill rod system. The adjustable multi-hole guide frame 4000 connects to or replaces the original single-axis pile driver's guide frame through a standardized interface. It is equipped with an adjustable drill rod clamping and guiding device corresponding to multiple mixing drill rods. The multi-functional drill bit connecting crossbeam 5000 is detachably connected to the bottom of multiple mixing drill rods, and its length can be adjusted according to the number of drill rods.
[0024] In this embodiment, the multi-mode mixing pile machine function conversion system includes the original single-axis mixing pile machine's power head 1000, frame, walking system, operating room, guide frame, detachable power expansion module 2000, extended mixing drill rod 3000, adjustable multi-hole guide frame 4000, and multi-functional drill bit connecting beam 5000. Through a set of highly modular additional components, without damaging the main structure of the original single-axis mixing pile machine, the system utilizes its original power source and walking chassis to achieve a functional upgrade from single-axis mixing to three-axis mixing through quick assembly and disassembly. The detachable power expansion module 2000, along with the original power head 1000, provides power to the extended mixing drill rod 3000. The newly added extended mixing drill rod 3000 and the original drill rod form a three-axis drill rod group. The original single-hole guide frame is replaced with an adjustable multi-hole guide frame 4000, and a special drill rod clamping and guiding device is installed. The multi-functional drill bit connecting beam 5000 is added to the bottom of the drill rod, connecting the three drill rods into one unit.
[0025] In one embodiment, the detachable power expansion module 2000 has an internal gear transmission mechanism. Its input shaft is connected to the output shaft of the original single-shaft pile driver power head 1000 via a quick-change coupling. The detachable power expansion module 2000 is an independent, sealed gearbox. It has a single-stage helical cylindrical gear transmission mechanism, specifically including one input shaft, one intermediate transmission shaft, and two output shafts. The input shaft is precisely connected to the output shaft of the original single-shaft pile driver power head 1000 via a quick-change coupling. Power is input from this shaft and synchronously distributed to the two output shafts via the gear set at a 1:1 transmission ratio, enabling the three mixing drill rods to rotate synchronously. The gearbox uses splash lubrication to ensure smooth transmission, low noise, and long service life. The coupling can be a flange-type coupling with a positioning stop and a quick-locking pin.
[0026] In one embodiment, the detachable power extension module 2000 can be selectively installed on one or more sides of the original power head 1000 via a quick-connect structure including a hydraulic locking mechanism and an automatic positioning system. This module can be configured as a dual-axis or tri-axis extension module, internally employing a planetary gear transmission mechanism. It obtains power from the original power head 1000 through a quick-connect mechanism and drives the extension drill pipes at a set transmission ratio, ensuring that all drill pipes rotate synchronously and in the same direction.
[0027] In one embodiment, the extended stirring drill rod assembly 3000 is connected to the output shaft of the detachable power extension module 2000 via a coupling, and together with the original single-axis drill rod, they form a multi-axis stirring system.
[0028] In one embodiment, the adjustable multi-hole guide frame 4000 connects to or replaces the original guide frame via a standardized interface. It is equipped with a hydraulically controlled movable bearing seat as a drill pipe clamping and guiding device, which can be steplessly adjusted on the guide rail to adapt to different pile diameter requirements. The bearing seat also integrates an intelligent lubrication system.
[0029] In one embodiment, the multi-functional drill bit connecting beam 5000 adopts a modular design, which can accommodate different numbers of drill rods by adding or removing connecting sections and using a pin-type quick-connect structure and safety locking device, connecting the bottom of each drill rod to maintain their synchronous operation and stable spacing. In one embodiment, the intelligent control system is used to monitor and control parameters such as the rotational speed, torque, and drilling depth of multiple mixing drill rods in real time to ensure construction quality.
[0030] The replacement process is as follows: First, preparations were made before construction. The original single-axis pile driver's mixing drill rod, drill bit, and original guide frame were disassembled.
[0031] Install the power extension module: Use hoisting equipment to lift the selected dual-axis or tri-axis detachable power extension module 2000 to the side of the original power head 1000. The automatic positioning system on the module first performs initial positioning, and then the hydraulic locking mechanism is activated to firmly lock the module to the side wall of the power head 1000. At this time, the quick docking mechanism on the module's input shaft completes docking with the output shaft of the original power head 1000.
[0032] Install the guide system: Hoist the adjustable multi-hole guide frame 4000 onto the main frame and fix it to the original guide frame mounting base through its standardized interface.
[0033] Install the drill rod and crossbeam: On the ground, assemble the modular connecting sections of the multi-functional drill bit connecting crossbeam 5000 to the required length using pins and safety lock pins, and connect them to each drill bit via flanges. Lift the assembly as a whole, connecting the central drill bit to the original single-shaft drill rod, and the drill bits on both sides to the extended mixing drill rod 3000. Finally, connect the upper end of the extended drill rod to the output shaft of the detachable power extension module 2000 via a coupling.
[0034] Adjusting the guide device: The adjustable multi-hole guide frame 4000 is fitted onto the three drill rods. The position of each movable bearing seat is adjusted through the hydraulic system to precisely clamp each drill rod, and then locked.
[0035] In three-axis working mode, the original pile driver's power system is activated, and power is synchronously distributed to the three drill rods via the detachable power extension module 2000. The intelligent control system monitors various parameters. The winch system lowers the entire drill rod assembly for mixing operations. The adjustable multi-hole guide frame 4000 ensures verticality, and the multi-functional drill bit connecting beam 5000 ensures synchronization at the bottom.
[0036] To restore the single-axis mode, disassemble each expansion module, drill rod, crossbeam, and guide frame in reverse order, and then reassemble the original single-axis components.
[0037] The detachable power expansion module 2000 is rigidly connected to the side wall of the power head 1000 via a quick-connect structure. This quick-connect structure includes a positioning component and a fastening component. The positioning component, located at the mating surface of the housing, includes at least two tapered positioning pins, which provide precise positioning during initial installation to ensure proper alignment of the shaft holes of the quick-change coupling. The fastening component uses several sets of high-strength precision bolts (M20-M24) evenly distributed around the perimeter of the housing. These bolts securely fasten the housing of the detachable power expansion module 2000 to the reinforced side plate of the power head 1000, forming a stable anti-torsional structure.
[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0039] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
