Description

Technical Field

[0001] This utility model relates to the field of pile driver technology, specifically to a pile driver with enhanced stability. Background Technology

[0002] Piling machines, as commonly used engineering machinery, are widely used in pile foundation construction for buildings, ports, bridges, water conservancy and hydropower projects. Traditional piling machines mainly consist of an upper frame, lower frame, lifting platform, drive system, and impact system. Their working principle involves the drive system driving the impact system to drive piles into the ground, thereby reinforcing the foundation and improving its bearing capacity. With the continuous expansion of construction projects and the increasing complexity of construction conditions, higher requirements are placed on the stability and construction efficiency of piling machines.

[0003] However, existing pile drivers have many problems and shortcomings in actual use. First, the ground support structure of traditional pile drivers is simple, making it difficult to maintain good stability under different geological conditions. Especially in complex terrain environments such as soft soil and slopes, tilting, sinking, or displacement are prone to occur, affecting pile driving accuracy and construction safety. Second, the lifting system of existing pile drivers lacks flexibility and is inconvenient to adjust, making it difficult to adapt to construction needs at different heights and angles. In addition, the structural design of traditional pile drivers lacks effective reinforcement and stabilization devices, making them prone to mechanical vibration and structural deformation during long-term high-intensity operation, reducing equipment lifespan and work efficiency.

[0004] Therefore, there is an urgent need to design a new type of pile driver with a reasonable structure, strong stability, and wide adaptability. By improving the lower frame support structure, optimizing the lifting system, and adding stabilizing mechanisms, the technical problems of existing pile drivers, such as poor stability under complex terrain conditions, inconvenient lifting and adjustment, and insufficient structural strength, can be solved, thereby improving the overall performance and construction effect of the pile driver and meeting the actual needs of modern engineering construction.

[0043] Please see Figure 1-5 This utility model provides a technical solution: a pile driver with enhanced stability, comprising:

[0044] Upper frame 1;

[0045] The lower frame 2 is located at the bottom of the upper frame 1. The upper frame 1 and the lower frame 2 are fixedly connected by a side frame 4 and several sets of guide support rods 3. A rack 8 is fixedly connected to one side of the side frame 4.

[0046] The lifting platform 5 is movably mounted on several sets of guide support rods 3. The top of the lifting platform 5 is equipped with a drive motor 6 and a linkage frame 9. The motor shaft of the drive motor 6 passes through the lifting platform 5 and is connected to an auger 7. The linkage frame 9 is fixedly connected to the drive motor 6, and the top of the linkage frame 9 is equipped with a lifting motor 10. The motor shaft of the lifting motor 10 is connected to a drive gear 11.

[0047] Several sets of stabilizing mechanisms are arranged in a regular circular array on the lower frame 2.

[0048] Specifically, the guide support rod 3 is fitted through the lifting platform 5 with a clearance fit, and the guide support rod 3 has a guiding function for the lifting platform 5.

[0049] Specifically, the side frame 4 and guide support rod 3 installed between the upper frame 1 and the lower frame 2 form a stable overall frame structure, effectively improving the overall rigidity and deformation resistance of the equipment. The movable sleeve design of the lifting platform 5 and the guide support rod 3, combined with the power transmission system of the drive motor 6, auger 7, and rack 8, enables smooth and precise lifting control of the lifting platform 5, meeting the construction needs at different heights. The coordinated design of the linkage frame 9 and the lifting motor 10 enhances the reliability and flexibility of the lifting system, while the meshing transmission mechanism of the drive gear 11 and the rack 8 ensures the stability and accuracy of the lifting process.

[0050] Specifically, this application forms a stable and reliable ground support system by setting several sets of stabilizing mechanisms in a regular circular array on the lower frame 2. This design greatly enhances the overall stability of the pile driver under various complex terrain conditions, effectively preventing the equipment from tilting, sinking or displacing during operation. It is particularly suitable for construction operations in complex terrain environments such as soft soil and slopes, ensuring pile driving accuracy and construction safety.

[0051] The drive gear 11 meshes with the rack 8, driving the drive gear 11 to rotate and thus move the lifting platform 5 up and down. Specifically, after the lifting motor 10 drives the drive gear 11 to rotate, the meshing transmission between the drive gear 11 and the rack 8 enables the synchronous lifting of the lifting platform 5 and the drive motor 6. The drive motor 6 then drives the auger 7 to rotate, achieving pile driving. Furthermore, the drive of the lifting motor 10 enables precise control and smooth movement of the lifting platform 5. Compared with traditional hydraulic lifting systems, this mechanical transmission mechanism features fast response, high precision, and simple control, greatly improving the flexibility of equipment adjustment and ease of operation. In addition, this transmission mechanism has a simple structure, is easy to maintain, and has a long service life, effectively reducing the equipment's failure rate and maintenance costs, and improving the economy and reliability of the pile driver.

[0052] Reference manual attached Figure 2 Stable institutions include:

[0053] The reinforcing frame 12 is fixedly connected to the lower frame 2;

[0054] The lower side connecting column 13 is fixedly connected to the reinforcing frame 12;

[0055] The base support block 14 is connected to the lower side connecting column 13 below;

[0056] The fixing cylinder 15 is fixed to the top of the base support block 14;

[0057] The limiting steel ball 16 is integrally connected to the bottom of the side lower connecting column 13;

[0058] The threaded ring 17 is fastened and connected to the lower end of the side connecting post 13.

[0059] Specifically, the multi-layered, multi-component stabilization mechanism design in this application significantly enhances the ground fixation effect of the pile driver. The fixed connection between the reinforcing frame 12 and the lower frame 2 strengthens the overall structural strength; the connection design between the side lower connecting column 13 and the base support block 14 enables effective force transmission; the combined application of the fixing cylinder 15, the limiting steel ball 16, and the fastening threaded ring 17 forms a quick-locking mechanism, facilitating the installation and disassembly of the stabilization mechanism. This integrated design not only improves the stability and safety of the pile driver but also takes into account the portability and flexibility of the equipment, making it particularly suitable for construction sites that require frequent movement and repositioning, greatly improving project efficiency and construction quality.

[0060] Reference manual attached Figure 2-3The outer surface of the fastening threaded ring 17 is connected to the inner wall of the fixed cylinder 15 via a threaded structure. The inner diameter of the fastening threaded ring 17 is smaller than the outer diameter of the limiting steel ball 16, and the outer diameter of the limiting steel ball 16 is matched with the inner diameter of the fixed cylinder 15. Specifically, the design of the fastening threaded ring 17 and the fixed cylinder 15 connected by a threaded structure, combined with the dimensional fit between the limiting steel ball 16 and the inner diameter of the fixed cylinder 15, forms an efficient and reliable quick-locking mechanism. This design allows the side lower connecting post 13 to be precisely positioned in the fixed cylinder 15 and securely locked by the fastening threaded ring 17, preventing loosening or displacement during use. The design that the inner diameter of the fastening threaded ring 17 is smaller than the outer diameter of the limiting steel ball 16 prevents the fastening threaded ring 17 from detaching from the side lower connecting post 13, greatly improving the reliability and safety of the connection. The locking mechanism is easy to operate, requires no special tools, greatly reduces the time for equipment installation and adjustment, and improves construction efficiency. At the same time, the mechanism is easy to disassemble, which facilitates the transportation and storage of the equipment, further enhancing the practicality and economy of the pile driver.

[0061] Reference manual attached Figure 4 The bottom of the base support block 14 is integrally connected with several sets of square stabilizing protrusions 18 in a regular matrix. Specifically, the regular matrix arrangement of the square stabilizing protrusions 18 at the bottom of the base support block 14 greatly increases the contact area and friction with the ground, forming a more stable support foundation. This design is particularly suitable for loose ground conditions such as soft soil and sand, effectively preventing the pile driver from sliding, sinking, or tilting during operation. The square stabilizing protrusions 18 have better torsional resistance than circular or other shapes, and can more effectively resist the horizontal forces and torques generated during pile driving, maintaining the stability of the equipment position. The regular matrix arrangement also ensures the uniform distribution of support force, avoids local stress concentration, extends the service life of the base support block 14, improves the reliability and durability of the entire stabilization mechanism, and provides a strong guarantee for the long-term stable operation of the pile driver.

[0062] Reference manual attached Figure 5The base support block 14 contains several sets of threaded tie rods 19 interlocked within a threaded structure, arranged in a regular matrix. Specifically, these threaded tie rods 19 form a deep fixing system, significantly enhancing the connection strength between the piling machine and the ground. The threaded tie rods 19 penetrate deep into the ground, forming a tight bond with the soil, greatly improving pull-out resistance and lateral resistance, effectively preventing displacement or overturning of the piling machine during high-intensity operations. The threaded structure design allows the threaded tie rods 19 to adjust their insertion depth according to soil conditions, providing strong adaptability and flexibility suitable for various complex terrain environments. The multiple sets of threaded tie rods 19 arranged in a regular matrix form a multi-point fixed support system, ensuring uniform distribution of support force and overall stability. Furthermore, the use of threaded tie rods 19 greatly reduces vibration transmission during piling, protecting equipment components, extending the service life of the piling machine, and also reducing the impact on the surrounding environment and noise pollution.

[0063] Specifically, when using it, the base support block 14 with square stabilizing protrusions 18 or the base support block 14 with threaded tie rods 19 can be selected according to the actual construction environment.

[0064] The lower frame 2 includes an inner ring 201 and an outer ring 202. The inner ring 201 is integrally connected to the inner wall of the outer ring 202. One end of the reinforcing frame 12 is tangentially and integrally connected to the outer surface of the inner ring 201, and the bottom of the reinforcing frame 12 is perpendicularly and integrally connected to the top of the outer ring 202. Specifically, the inner sides of the inner ring 201 and the outer ring 202 can be used for the installation movement of the auger 7. The lower frame 2 adopts a double-ring structure design combining the inner ring 201 and the outer ring 202, which greatly enhances the overall strength and rigidity of the lower frame 2. The integral connection of the inner ring 201 and the outer ring 202 forms a closed ring support structure with extremely high load-bearing capacity and deformation resistance, effectively bearing and dispersing the impact and vibration generated during pile driving. The tangential connection between the reinforcing frame 12 and the outer surface of the inner ring 201, as well as the vertical connection with the top of the outer ring 202, forms a scientifically sound mechanical transmission system. This ensures uniform force distribution and effective transmission, avoids localized stress concentration, and further improves the reliability and safety of the overall structure. This design not only enhances the connection strength between the lower frame 2 and the stabilizing mechanism but also optimizes the stress state of the entire piling machine, enabling the equipment to maintain good stability and durability during high-intensity, long-term continuous operation, greatly improving piling efficiency and construction quality.

[0065] The working principle of this enhanced stability piling machine is as follows: First, after the piling machine is transported to the construction site, it is fixed by several sets of stabilizing mechanisms. Depending on the actual construction environment, a base support block 14 with square stabilizing protrusions 18 is selected. The square stabilizing protrusions 18 at the bottom of the base support block 14 in the stabilizing mechanism are in full contact with the ground, increasing friction and support area; or a base support block 14 with threaded tie rods 19 is selected, and the threaded tie rods 19 are screwed into the ground through the base support block 14 to form a deep fixation. The limiting steel ball 16 at the bottom of the side lower connecting column 13 is inserted into the fixing cylinder 15 and locked by the threaded connection between the fastening threaded ring 17 and the fixing cylinder 15, ensuring a firm connection between the components of the stabilizing mechanism. Multiple sets of stabilizing mechanisms arranged in a regular circular array work together to form a multi-point support system, greatly improving the overall stability of the piling machine. After the equipment is fixed, the lifting motor 10 drives the drive gear 11 to rotate, which meshes with the rack 8 fixed on the side frame 4, driving the lifting platform 5 to move up and down along the guide support rod 3 to adjust to the required working height. The drive motor 6 on the lifting platform 5 is connected to the auger 7 through the motor shaft. When pile driving is required, the drive motor 6 is started, driving the auger 7 to rotate at high speed, generating a strong impact and rotational force to drive the pile into the ground. During operation, the structural design of the inner ring 201 and outer ring 202 of the lower frame 2, as well as the overall force-bearing system formed with the reinforcing frame 12, ensures that the equipment remains stable when subjected to strong impact and vibration. The guide support rod 3 ensures the smooth movement of the lifting platform 5, avoiding swaying and deviation. When it is necessary to adjust the working height or angle, precise adjustment can be achieved simply by controlling the lifting motor 10, without the need to re-fix the entire equipment, greatly improving the convenience of operation and work efficiency. After piling is completed, the stabilizing mechanism can be quickly released by disassembling the fastening threaded ring 17, removing the limiting steel ball 16 and the side lower connecting column 13, and pulling out the threaded tie rod 19, facilitating the movement and relocation of the equipment. The entire process is simple to operate, and the installation and disassembly are rapid, greatly improving construction efficiency and equipment utilization.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
