[0025] It should be noted that the hydraulic pile cutting machine body 1 is sleeved on the outside of the pile foundation 2. The body is composed of multiple bases 3, which are equidistantly distributed to ensure stable operation of the equipment. A cylinder 4 is installed on one side of each base 3, and a drill rod 5 is slidably connected inside the cylinder 4. By controlling the telescopic movement of the cylinder 4, the drill rod 5 can be extended and retracted accordingly to perform pile cutting operations on the pile foundation 2. On the other side of the base 3, a positioning cylinder 6 is fixedly connected. One end of the drill rod 5 passes through the base 3 and is arranged inside the positioning cylinder 6. This design not only enables the drill rod 5 to maintain a stable trajectory during the telescopic process, but also allows the positioning cylinder 6 to resist the pile foundation 2, thereby improving the accuracy and efficiency of the pile cutting operation.

[0026] See also Figures 1 to 6 , the connecting assembly 9 includes: a plug rod 901, a sleeve 902, a rotating cylinder 903, an elliptical ball block 904 and a torsion spring 905. The bottom of the connecting plate 7 below one side of the base 3 is fixedly connected with the sleeve 902, and the bottom of the connecting plate 7 below one side of the base 3 is rotatably connected with the rotating cylinder 903, and the rotating cylinder 903 is sleeved on the outside of the sleeve 902.

[0029] It should be noted that the guide groove 907 is used to guide the elliptical ball block 904 to slide inside the sleeve 902 during the insertion of the plug rod 901, and cooperate with the elastic effect of the torsion spring 905 to achieve the positioning and stable connection of the plug rod 901;

[0030] See also Figures 1 to 6The bottom end of the plug rod 901 is provided with a chamfer 908;

[0031] It should be noted that the chamfer 908 is used to guide the elliptical ball block 904 to slide inside the sleeve 902 when the plug-in rod 901 is inserted between the connecting plate 7 and the embedded plate 8;

[0032] See also Figures 1 to 6 , a baffle 909 is fixedly connected to the top of the plug rod 901;

[0033] It should be noted that the baffle 909 is used to limit the insertion depth of the plug rod 901 to prevent the plug rod 901 from being over-inserted and damaging the connecting assembly 9;

[0034] See also Figures 1 to 6 , a circular eave 910 is provided at the bottom end of the rotating drum 903;

[0035] It should be noted that the annular eave 910 is used to make the rotation adjustment of the rotating drum 903 more labor-saving and convenient;

[0036] See also Figures 1 to 6 , two hydraulic pipelines 10 are provided between the oil cylinders 4, and the hydraulic pipelines 10 are used to connect adjacent oil cylinders 4 in parallel;

[0037] It should be noted that: to ensure uniform distribution and synchronous control of the hydraulic oil, the adjacent oil cylinders 4 can work synchronously, thereby improving the working performance and stability of the entire hydraulic pile cutter body 1;

[0038] See also Figures 1 to 6 , the top of the base 3 is fixedly connected with a lifting ring 11;

[0039] It should be noted that the hoisting ring 11 is used to facilitate the hoisting and transportation of the entire hydraulic pile cutter body 1, thereby improving the mobility and operating efficiency of the equipment.

[0040] The working principle of the annular partition plate assisted hydraulic pile cutting equipment provided by the utility model is as follows: after the drilling operation is completed and before the steel cage is installed, the staff will directly insert the annular partition plate into the main reinforcement of the exposed foundation and the outer end surface of the acoustic detection tube of the steel cage. The main purpose of this is to wrap these important structures to avoid damage in the subsequent pile cutting process. The hoop-type pile cutter is used to perform circumferential cutting at the connection of the pile foundation 2 and a certain position above to form an annular cutting belt. The cutting depth needs to be controlled within a certain range to ensure that the main reinforcement of the pile foundation 2 is not damaged;

[0041] Then, the hydraulic pile cutter body 1 is used to break the pile head. The hydraulic pile cutter body 1 is sleeved on the outside of the pile foundation 2. The body is composed of a plurality of bases 3. These bases 3 are evenly distributed to ensure the stable operation of the equipment. A cylinder 4 is installed on one side of each base 3. A drill rod 5 is slidably connected inside the cylinder 4. By controlling the telescopic movement of the cylinder 4, the drill rod 5 can be extended and retracted accordingly to perform a pile cutting operation on the pile foundation 2.

[0042] On the other side of the base 3, a positioning tube 6 is fixedly connected, and one end of the drill rod 5 passes through the base 3 and is arranged inside the positioning tube 6. This design not only allows the drill rod 5 to maintain a stable trajectory during the extension and retraction process, but also allows the positioning tube 6 to resist the pile foundation 2, thereby improving the accuracy and efficiency of the pile cutting operation;

[0043] In order to enhance the connection strength and stability between the bases 3, a connecting plate 7 is symmetrically fixedly connected to one side of the base 3 perpendicular to the positioning cylinder 6, and an embedded plate 8 is symmetrically fixedly connected to the other side. These embedded plates 8 are arranged between two adjacent connecting plates 7 and fit with the connecting plates 7.

[0044] A connecting assembly 9 is installed between the connecting plates 7. When it is necessary to connect adjacent bases 3, the plug-in rod 901 is slidably inserted through the connecting plate 7, and ensure that the plug-in rod 901 passes through the corresponding two embedded plates 8. At this time, the chamfer 908 at the bottom end of the plug-in rod 901 will guide the elliptical ball block 904 to slide in the sleeve 902, and the rotating cylinder 903 rotates under the action of the torsion spring 905. When the elliptical ball block 904 moves to align with the annular groove 906 at the bottom end of the plug-in rod 901, the rebound of the torsion spring 905 causes the rotating cylinder 903 to reverse, and one end of the elliptical ball block 904 is embedded in the annular groove 906, and the other end is fitted with the inner wall of the sleeve 902, so as to realize the positioning of the plug-in rod 901, thereby ensuring the stability of the connection;

[0045] During the pile cutting operation, the drill rod 5 cuts off the pile foundation 2 by controlling the telescopic movement of the oil cylinder 4. Since the bases 3 are firmly connected by the connecting assembly 9, the entire hydraulic pile cutting machine body 1 can maintain a stable posture, thereby improving the accuracy and efficiency of the pile cutting operation.

[0046] In addition, the oil cylinders 4 are connected in parallel through hydraulic pipelines 10 to ensure that adjacent oil cylinders 4 can work synchronously, further improving the overall performance of the equipment. The lifting ring 11 fixedly connected to the top of the base 3 facilitates the lifting and transportation of the entire hydraulic pile cutter body 1.

[0047] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
