Description

Technical Field

[0001] This application relates to the field of water conservancy engineering construction, and in particular to an excavator piling mechanism that facilitates piling. Background Technology

[0002] In daily life, especially in the construction of water conservancy projects, excavators are often used, such as for dredging river channels and driving piles on both sides. Traditionally, pile driving is done manually by inserting a portion of the wooden pile into the river channel before pressing it down with an excavator bucket, and then inserting the next wooden pile.

[0003] The current piling technology has the following problems: 1. Difficulty in controlling verticality: The geological conditions at the bottom of the river are complex and variable, making it difficult to accurately control the force and direction when directly pressing down, which easily leads to the tilting of the fir piles. Non-vertical piles reduce bearing capacity and may break or shift due to uneven stress over time. Verticality control during piling is a challenge. Due to the potentially complex and variable geological conditions at the bottom of the river, if the excavator cannot accurately control the force and direction during piling, the fir piles are prone to tilting. Non-vertical piles not only affect their bearing capacity but may also break or shift due to uneven stress during subsequent use, thus weakening the river protection effect. 2. Pile bodies are easily damaged or cracked: Fir piles themselves have low compressive strength (low density). Improper operation during direct pressing may cause excessive local stress, leading to cracking or surface damage, affecting structural integrity. 3. Insufficient spacing and arrangement accuracy: When operating with excavators in conjunction with manual labor, insufficient support or excessive pressing speed may lead to uneven pile spacing. Excessive spacing weakens the protective effect, while insufficient spacing increases costs and affects water flow. 4. Equipment operational limitations: Excavator bucket driving of piles requires inverted wooden piles and manual support, demanding a high level of operator skill. If the driving depth is insufficient or the stability is poor, secondary adjustments are required, which reduces efficiency.

[0004] Based on this, this application provides an excavator piling mechanism that facilitates piling to solve the above problems. Utility Model Content

[0005] In order to improve the efficiency of river piling and accurately control the verticality of wooden piles, this application provides an excavator piling mechanism that facilitates piling.

[0006] The excavator piling mechanism provided in this application, which facilitates piling, adopts the following technical solution:

[0007] An excavator piling mechanism for easy piling includes:

[0008] Mounting bracket for mounting on the excavator boom;

[0009] A clamp is mounted on the side of the mounting base, and the clamp can be closed or opened;

[0010] A vibrator is fixed inside the mounting base. A pile driving head is installed at the output end of the vibrator. A limit ring is provided at the bottom end of the pile driving head. A limiting space is formed between the inner wall of the limit ring and the end of the pile driving head to restrict the movement of the end of the wooden pile.

[0011] By adopting the above technical solutions, a piling mechanism for excavators that facilitates piling has been realized, effectively solving problems such as difficulty in verticality control, easy damage to the pile body, insufficient spacing and arrangement accuracy, and limitations in equipment operation during traditional piling processes. Specific effects are as follows: The cooperation between the mounting base and the excavator's boom ensures overall structural stability, providing reliable support for the piling process and reducing pile tilting caused by equipment instability. The clamp design allows for flexible adjustment to accommodate piles of different sizes, improving piling efficiency and accuracy while avoiding safety hazards associated with manual support. The combination of the vibrator and the pile head utilizes vibration energy to reduce soil resistance, making it easier to insert the pile into the target position, reducing damage to the pile and improving construction efficiency. The limiting space formed by the limiting ring and the end of the pile head allows for precise control of the pile insertion depth and position, ensuring pile verticality and avoiding structural problems caused by uneven stress.

[0012] Optionally, the limiting ring is a solid circular ring.

[0013] By adopting the above technical solution, the design of the full-circle solid ring can provide complete limiting space, effectively preventing the wooden pile from shifting or tilting during the piling process, thereby ensuring the verticality and stability of the wooden pile and improving the accuracy and reliability of piling.

[0014] Optionally, the clamp includes a fixing plate, on which a slider is fixed, and a guide rail is provided on the side of the mounting base. The slider is slidably connected to the guide rail, and a locking element for locking the slider and the guide rail is provided on the slider.

[0015] By adopting the above technical solution, a slider is provided on the fixing plate of the clamp, and a guide rail is provided on the side of the mounting base, allowing the clamp to slide and adjust its position along the guide rail, thereby quickly adjusting the installation position of the clamp. At the same time, a locking component is provided on the slider to lock and fix the slider to the guide rail, ensuring the stability of the clamp during the piling process, avoiding positional displacement due to vibration, and improving piling accuracy and construction safety.

[0016] Optionally, the locking element is a 7-shaped locking handle.

[0017] By adopting the above technical solution, the figure-7 locking handle makes it easier for operators to lock and release the slider, thereby quickly adjusting and fixing the position of the clamp, improving the working efficiency and flexibility of the piling mechanism.

[0018] Optionally, both ends of the guide rail are located outside the mounting base.

[0019] By adopting the above technical solution, the clamp can be installed or removed directly from both ends of the guide rail, further improving the installation and removal efficiency of the clamp and facilitating subsequent maintenance.

[0020] Optionally, the gripper includes two symmetrically arranged grippers, and the inner side of the grippers is provided with a rubber pad or anti-slip teeth.

[0021] By adopting the above technical solution, the clamp includes two symmetrically arranged jaws, which can more firmly clamp the wooden pile and prevent the pile from shifting during the pile driving process. The rubber pads or anti-slip teeth on the inner side of the jaws further increase the friction between the jaws and the wooden pile, effectively preventing the wooden pile from sliding or falling off under vibration or impact, thereby improving the stability and safety of the pile driving operation.

[0022] Optionally, a micron-sized diamond layer is deposited on the end face of the pile head.

[0023] By adopting the above technical solution, depositing a micron-sized diamond layer on the end face of the pile head can significantly improve the hardness and wear resistance of the pile head, thus effectively coping with high-hardness soils under extreme conditions such as frozen soil and reefs. Specific effects include: 1) enhancing the wear resistance of the pile head and extending its service life; 2) improving rock penetration efficiency, increasing it by 3 times compared to traditional pile heads; and 3) ensuring stability and accuracy during the pile driving process and reducing construction interruptions caused by equipment wear.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The limiting space formed by the limiting ring and the end of the pile head can precisely control the insertion depth and position of the wooden pile, ensure the verticality of the pile, and avoid structural problems caused by uneven force.

[0026] 2. The combined use of a vibrator and a pile driver can efficiently transmit vibration energy, ensuring that the wooden piles penetrate the soil quickly and greatly improving pile driving efficiency;

[0027] 3. The clamp's foldable or unfoldable design facilitates adjustment of the pile's position and secure clamping, adapting to piles of different diameters and enhancing the equipment's versatility and construction flexibility. Attached Figure Description

[0033] The following will be combined with the appendix Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. The described embodiments are only possible technical implementations of this utility model and not all possible implementations. Those skilled in the art can obtain other embodiments in conjunction with the embodiments of this utility model without creative effort, and these embodiments are also within the protection scope of this utility model.

[0034] The inventors of this application have discovered that traditional piling methods in the prior art have problems such as difficulty in controlling verticality, easy damage to the pile body, insufficient spacing and arrangement accuracy, and limitations in equipment operation. To address these issues, this application mainly adopts the following solution, which achieves the effect of significantly improving piling efficiency and quality through mechanical structure innovation and thermodynamic auxiliary design. The following is a further detailed description of this application.

[0035] Example 1

[0036] This application provides an excavator piling mechanism for easy piling, referring to... Figure 1 and Figure 2 The system includes a mounting base 1, a clamp 2, and a vibrator 3. The mounting base 1 is mounted on the excavator's boom, and the clamp 2 is mounted on the side of the mounting base 1, capable of closing or opening. The vibrator 3 is fixed inside the mounting base 1, and a pile driving head 4 is mounted on the output end of the vibrator 3. A limit ring 5 is provided at the bottom end of the pile driving head 4, forming a limiting space 51 between the inner wall of the limit ring 5 and the end of the pile driving head 4 to restrict the movement of the pile end. This structural design achieves precise positioning and efficient pile driving, while ensuring the stability of the pile during the driving process, avoiding the verticality deviation and pile damage problems caused by manual operation in traditional methods.

[0037] Specifically, the mounting base 1 can be installed on the excavator boom by bolt connection, and the mounting base 1 can be rotated by the excavator boom to adjust the clamping angle or piling angle. The material of the mounting base 1 can be high-strength alloy steel or aluminum alloy, etc., to meet the usage requirements under different working conditions.

[0038] The clamp 2 includes a fixed plate 21 and two symmetrically arranged grippers 22 mounted on the fixed plate 21. The fixed plate 21 is fixed to the side of the mounting base 1. The grippers 22 can be driven by a hydraulic cylinder or a pneumatic cylinder to achieve closing or unfolding actions.

[0039] In a preferred embodiment, the inner side of the gripper 22 may be provided with a rubber pad or anti-slip teeth to increase the friction with the surface of the wooden pile and prevent the wooden pile from sliding during the piling process. In addition, the opening angle of the gripper 2 can be adjusted according to actual needs. For example, when the diameter of the wooden pile is large, the opening angle of the gripper can be appropriately increased to ensure the firmness of the grip.

[0040] In a preferred embodiment, the limiting ring 5 is a solid circular ring, and its inner wall forms a limiting space 51 with the end of the pile head 4. The size of this space can be adjusted according to the diameter of the wooden pile to ensure that the end of the wooden pile does not shift during the piling process. The limiting ring 5 can be made of stainless steel or wear-resistant alloy to extend its service life. In other embodiments, the limiting ring 5 can also be composed of multiple arc blocks, as long as they can restrict the radial movement of the wooden pile.

[0041] In another embodiment, the inner wall of the limiting ring 5 is provided with multiple protrusions to increase the friction with the end of the wooden pile and prevent the pile from rotating during piling. The protrusions can be cylindrical, prismatic, or conical in shape, depending on the specific application requirements.

[0042] Furthermore, in a preferred embodiment, a micron-sized diamond layer is deposited on the four end faces of the pile head, with a thickness typically controlled between 0.1 mm and 0.3 mm. Too thin a layer may result in insufficient wear resistance, while too thick a layer increases manufacturing costs. The diamond layer can be prepared using chemical vapor deposition (CVD) or physical vapor deposition (PVD) processes.

[0043] The implementation principle of this embodiment is as follows: the wooden pile is precisely positioned by the clamp 2, and the high-frequency vibration energy generated by the vibrator 3 is transmitted to the pile head 4, so that the pile head 4 can quickly drive the wooden pile under the action of high-frequency vibration, thereby achieving efficient pile driving. The design of the limiting space 51 can precisely control the position of the wooden pile, ensure the verticality of the pile, and avoid structural problems caused by uneven force.

[0044] Example 2

[0045] The difference between this embodiment and Embodiment 1 is that the clamp 2 is movable on the mounting base 1. (Refer to...) Figure 3 A slider 23 is fixed on the back of the fixing plate 21, and a guide rail 24 is provided on the side of the mounting base 1. The slider 23 is slidably connected to the guide rail 24, and a locking part 25 is provided on the slider 23 to lock the slider 23 and the guide rail 24.

[0046] The slider 23 can be made of polytetrafluoroethylene (PTFE) or polymer composite material to reduce frictional resistance and extend service life. The cross-sectional shape of the guide rail 24 can be dovetail, rectangular, circular or T-shaped. For example, the T-shaped guide rail 24 provides better guiding performance, and the circular guide rail 24 is easier to process and install.

[0047] In a preferred embodiment, the two ends of the guide rail 24 are located outside the mounting base 1, and the clamp 2 can be quickly installed and removed from the mounting base 1, improving the convenience of maintenance.

[0048] In another embodiment, the locking element 25 is a L-shaped locking handle used to fix the slider 23 at a designated position on the guide rail 24. The locking handle can be made of stainless steel or engineering plastic; the former has higher strength and corrosion resistance, while the latter is lightweight and less expensive.

[0049] The embodiments of this application can adjust the installation position of the clamp 2, making the clamp 2 more convenient to maintain.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
