Description

Technical Field

[0001] This application relates to the field of pile driver technology, and more specifically, to a pile head and a pile driver. Background Technology

[0002] In the field of photovoltaic support, traditional pile drivers typically use grooved pile heads. The column is fixed and piles are driven by inserting the column head into the groove. The process of matching the column with the grooved pile head is time-consuming and affects the pile driving efficiency.

[0003] At the same time, when dealing with columns of different specifications, the piling machine needs to change the pile head tooling to match the corresponding column specifications. Not only does it need to carry multiple sizes of pile heads, but the time required to change the pile heads also leads to low piling efficiency and increased labor and time costs.

[0004] Therefore, this application proposes a pile head for a pile driver and a pile driver to solve the aforementioned problems. Utility Model Content

[0005] To address the aforementioned problems, this application provides a pile head for a pile driver and a pile driver.

[0006] The technical solution for a pile head for a pile driver provided in this application is as follows:

[0007] A pile head for a pile driver, for mating with the top of a column, the column comprising a web and flanges, including:

[0008] A fixing module is used for fixed connection with the pile driver;

[0009] A piling module, comprising a main body and multiple limiting members, wherein the main body is detachably connected to the fixing module for abutting against the top of the column; the multiple limiting members are disposed on the main body for abutting against the web and wing plates of the column.

[0010] Furthermore, the main body is provided with multiple through holes, and the limiting member is detachably connected to the main body through the through holes.

[0011] The above technical solution enhances the flexibility of the pile head. When facing columns of different specifications, the corresponding limiting parts can be easily replaced, enabling the pile head to adapt to more column specifications, further improving piling efficiency, reducing the manpower and time costs caused by changing pile head tooling, and the detachable limiting parts can be easily replaced individually when damaged, reducing maintenance costs.

[0012] Furthermore, the through hole is an oblong hole, which includes a first oblong hole. When the limiting member is connected to the main body through the first oblong hole, it is used to abut against the wing plate of the column.

[0013] Through the above technical solution, the design of the waist-shaped hole provides adjustable space for the installation of the limiting component. During the installation process, the position of the limiting component can be finely adjusted according to the actual position and size of the column wing plate, so that the limiting component fits better with the column wing plate and enhances the fixing effect.

[0014] Furthermore, the first waist-shaped hole extends longitudinally along a first direction, and the waist-shaped hole also includes a second waist-shaped hole extending longitudinally along a second direction. When the limiting member is connected to the main body through the second waist-shaped hole, it is used to abut against the web of the column.

[0015] The second direction is perpendicular to the first direction.

[0016] Through the above technical solution, this design enables the pile head to precisely limit the web and flange of the column from two vertical directions, fully adapting to the size changes of columns of different specifications, further improving the adaptability of the pile head to different columns, ensuring a stable connection under various conditions, and efficiently completing the piling operation.

[0017] Furthermore, the waist-shaped hole includes four first waist-shaped holes and two second waist-shaped holes. The two limiting members connected to the second waist-shaped holes are respectively used to abut against the opposite sides of the web of the column, and the four limiting members connected to the first waist-shaped holes are respectively used to abut against the two wing plates at opposite ends of the column.

[0018] The above technical solution ensures balanced positioning of all parts of the column. During the piling process, the column is subjected to uniform force in all directions, making it less prone to deviation or shaking. This greatly improves the accuracy and stability of piling, ensuring the smooth progress of the piling work, while also adapting to changes in the web and wing plate dimensions of columns of different specifications.

[0019] Furthermore, the fixing module includes fasteners and two oppositely arranged fixing plates, which are respectively connected to both ends of the pile driver via the fasteners.

[0020] The above technical solution provides a simple and reliable connection method that is easy to install and disassemble. It not only securely fixes the pile head to the pile driver, ensuring stability during the pile driving process, but also allows for easy disassembly of the fixing module when the pile head needs to be replaced or the pile driver needs maintenance, improving work efficiency and reducing the risk of the pile head falling off due to an unstable connection.

[0021] Furthermore, both of the fixing plates are provided with a slot on the side near the main body;

[0022] The piling module also includes snap-fit ​​parts located on opposite sides of the main body. Through the cooperation of the snap-fit ​​parts and the slot parts, the main body can be detachably connected to the fixing module.

[0023] Through the above technical solution, the two work together to achieve a detachable connection between the piling module and the fixing module. This connection structure makes the replacement of the piling module more convenient. When it is necessary to replace the piling module for different specifications of columns, simply separate or insert the snap-fit ​​part from the snap-fit ​​part. No complicated tools or operations are required, saving time and labor costs, and further improving the adaptability of the pile head to different columns.

[0024] Furthermore, a reinforcing plate is provided on the side of the two fixing plates that are close to each other.

[0025] Through the above technical solution, the reinforcing plate enhances the structural strength of the connection between the fixing plate and the pile driver, improves the overall stability of the fixing module, and can better withstand the impact force transmitted by the pile driver during the pile driving process, preventing the fixing plate from deforming due to stress and affecting the connection stability between the pile head and the pile driver.

[0026] Furthermore, each of the two fixing plates has a laterally extending connecting portion at one end near the main body, and a screw pair is provided between the two connecting portions. The screw pair is symmetrically fitted with limiting sleeves at both ends near the two connecting portions for limiting the hook of the pile driver.

[0027] Through the above technical solution, the limiting cylinder can limit the position of the pile driver hook, prevent the hook from shifting during the pile driving process, and ensure the normal operation of the pile driver when hoisting the column.

[0028] A pile driver, comprising the aforementioned pile head.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] (1) In this application, by setting the pile head of the pile driver to include a fixed module and a pile driving module that can be detachably connected, when facing columns of different specifications, only the pile driving module needs to be replaced to adapt to the corresponding column specifications, which not only significantly reduces the cost, but also greatly improves the convenience of disassembly and replacement.

[0031] (2) In this application, the limiting component is detachably connected to the main body. When facing columns of different specifications, only the limiting component of the corresponding specification needs to be replaced to achieve adaptation, thereby further improving the piling efficiency.

[0032] (3) In this application, multiple limiting members can be connected to the main body through the waist-shaped hole. Moving the limiting members along the length direction of the waist-shaped hole can change the spacing of the multiple limiting members to press against columns of different specifications, which significantly improves the versatility and applicability of the pile head of the pile driver.

[0045] See Figures 1 to 5 As shown, this application discloses a pile head for a pile driver, used to engage with the top of a column 3. The column 3 includes a web 31 and wing plates 32. In a specific embodiment, the column 3 is preferably an H-beam or a C-beam, and there are two wing plates 32 located at opposite ends of the web 31, with the web 31 perpendicular to the wing plates 32.

[0046] The pile head of the pile driver includes a fixed module 1 and a pile driving module 2. The fixed module 1 is used to be fixedly connected to the pile driver. The pile driving module 2 includes a main body 21 and multiple limiting members 22. The main body 21 is detachably connected to the fixed module 1 and is used to abut against the top of the column 3. The multiple limiting members 22 are provided on the main body 21 and are used to abut against the web plate 31 and the wing plate 32 of the column 3.

[0047] Specifically, the fixed module 1 can be adapted to various piling modules 2 of different specifications. The size and shape of the main body 21 of each piling module 2 are designed according to the different specifications of the columns 3. When facing columns 3 of different specifications or types, the columns 3 can be quickly and accurately adapted by directly replacing the piling module 2. This is especially suitable for situations where the specifications of the columns 3 vary greatly, which greatly improves piling efficiency. Moreover, the design of piling modules 2 of different specifications allows the piling head of the piling machine to adapt to the needs of various columns 3, enhancing the versatility and practicality of the piling head.

[0048] In this embodiment, by setting the pile head of the piling machine to include a detachably connected fixed module 1 and a piling module 2, when facing columns 3 of different specifications, the piling module 2 can be replaced to adapt to the corresponding specifications of the columns 3, without having to replace the entire pile head of the piling machine. This not only significantly reduces costs but also greatly improves the convenience of disassembly and replacement.

[0049] See Figures 1 to 5 As shown, the main body 21 is provided with multiple through holes, and the limiting member 22 is detachably connected to the main body 21 through the through holes; this enhances the flexibility of the pile head. When facing columns 3 of different specifications, the limiting member 22 can be easily disassembled and installed, and its position can be adjusted, so that the pile head can be adapted to more types of columns 3, further improving the piling efficiency and reducing the manpower and time costs caused by replacing pile head tooling. The detachable limiting member 22 is convenient to be replaced individually when damaged, reducing maintenance costs.

[0050] In one embodiment, the through hole is a circular hole, and the limiting member 22 is detachably connected to the main body 21 through the circular hole. Specifically, the main body 21 is provided with a circular hole through which the limiting member 22 passes. When dealing with columns 3 of different specifications, only the limiting member 22 of the corresponding specification needs to be replaced to achieve adaptation, without the need to frequently replace the piling module 2, thus saving time and costs.

[0051] In other possible embodiments, the main body 21 is provided with multiple sets of circular holes located at different positions on the main body 21 to accommodate columns 3 of different specifications. The limiting member 22 is fixedly connected to the sets of circular holes at different positions on the main body 21 to accommodate columns 3 of different specifications.

[0052] See Figures 1 to 5 As shown, the through hole is an oblong hole, including a first oblong hole 23. When the limiting member 22 is connected to the main body 21 through the first oblong hole 23, it abuts against the wing plate 32 of the column 3. The oblong hole design provides adjustable space for the installation of the limiting member 22, that is, the limiting member 22 can be moved along the length direction of the first oblong hole 23 to change the relative position and spacing of the limiting member 22 on the main body 21, thereby adapting to columns 3 of different specifications and significantly improving the versatility and applicability of the piling module 2. Specifically, during the installation process, the position and spacing of multiple limiting members 22 can be adjusted according to the actual size of the column 3, so that the limiting member 22 fits better with the wing plate 32 of the column 3 and enhances the fixing effect.

[0053] See Figures 1 to 5 As shown, the first waist-shaped hole 23 extends longitudinally along the first direction, and the waist-shaped hole also includes a second waist-shaped hole 24 extending longitudinally along the second direction. When the limiting member 22 is connected to the main body 21 through the second waist-shaped hole 24, it is used to abut against the web plate 31 of the column 3; the second direction is perpendicular to the first direction.

[0054] Specifically, refer to Figure 3 and Figure 4 The first direction is perpendicular to the wing plate 32 of the column 3, and the second direction is perpendicular to the web plate 31 of the column 3. This arrangement of the first waist-shaped hole 23 and the second waist-shaped hole 24 allows the pile head to precisely limit the web plate 31 and wing plate 32 of the column 3 from two perpendicular directions, fully adapting to the dimensional changes of different specifications of the column 3. This further improves the adaptability of the pile head to different columns 3, ensuring a stable connection under various conditions and efficiently completing the piling operation.

[0055] In other possible embodiments, by adjusting the relative position and spacing of the limiting member 22 on the main body 21 along the length direction of the waist-shaped hole, and by combining different numbers or specifications of limiting members 22, not only is the convenience of disassembly and replacement improved, but the versatility and applicability of the pile head of the pile driver are further enhanced.

[0056] Furthermore, the piling module 2 includes at least four limiting members 22, and the main body 21 is provided with at least two first waist-shaped holes 23 and two second waist-shaped holes 24. Specifically, the two first waist-shaped holes 23 are respectively located on the side where the two wing plates 32 of the column 3 are close to each other, and the two second waist-shaped holes 24 are respectively located on opposite sides of the web plate 31 of the column 3. The two limiting members 22 connected to the main body 21 through the first waist-shaped holes 23 are respectively used to abut against the side where the two wing plates 32 are close to each other, and the two limiting members 22 connected to the main body 21 through the second waist-shaped holes 24 are respectively used to abut against the opposite sides of the web plate 31.

[0057] Furthermore, by moving the limiting member 22 along the length direction of the first waist-shaped hole 23 (i.e., along the first direction) until the two limiting members 22 respectively abut against the two wing plates 32, the spacing of the two wing plates 32 of different specifications of the column 3 can be adapted; by moving the limiting member 22 along the length direction of the second waist-shaped hole 24 (i.e., along the second direction) until the two limiting members 22 respectively abut against the two sides of the web plate 31, the thickness of the web plate 31 of different specifications of the column 3 can be adapted, significantly improving the versatility and applicability of the pile head of the pile driver.

[0058] In one embodiment, column 3 is an H-beam. See also Figures 1 to 5 As shown, the waist-shaped holes include four first waist-shaped holes 23 and two second waist-shaped holes 24. Two limiting members 22 connected to the second waist-shaped holes 24 are respectively used to abut against opposite sides of the web 31 of the column 3. The four limiting members 22 connected to the first waist-shaped holes 23 are respectively used to abut against the two wing plates 32 at opposite ends of the column 3. The four limiting members 22 are arranged in pairs and are located on both sides of the web 31. This arrangement of the first waist-shaped holes 23 and the second waist-shaped holes 24 ensures balanced limiting of various parts of the column 3. During piling, the column 3 is subjected to uniform force in all directions, making it less prone to deviation or swaying, greatly improving the accuracy and stability of piling, ensuring smooth piling work, and adapting to changes in the dimensions of the web 31 and wing plates 32 of columns of different specifications.

[0059] Furthermore, the limiting member 22 includes a washer 26 and a bolt. The bolt passes through the through hole in the washer 26 and the main body 21 and is locked in place to fix the washer 26 to the main body 21. In addition, by replacing the washer 26 with different sizes, it is possible to adapt to different specifications of the column 3.

[0060] See Figure 1 , Figure 2 , Figure 4 and Figure 5 The fixing module 1 includes fasteners 11 and two oppositely arranged fixing plates 12. The two fixing plates 12 are respectively connected to both ends of the pile driver through the fasteners 11. This connection method is simple and reliable, and is easy to install and disassemble. It can not only firmly fix the pile head of the pile driver on the pile driver to ensure the stability during the pile driving process, but also make it easy to disassemble the fixing module 1 when it is necessary to replace the pile head or maintain the pile driver, thereby improving work efficiency and reducing the risk of the pile head falling off due to unstable connection.

[0061] See Figure 1 , Figure 2 , Figure 4 and Figure 5 Each of the two fixing plates 12 has a slot 13 on one side near the main body 21. The piling module 2 also includes a snap-fit ​​part 25 on opposite sides of the main body 21. Through the cooperation of the snap-fit ​​part 25 and the slot 13, the piling module 2 can be detachably connected to the fixing module 1. The two work together to achieve a detachable connection between the piling module 2 and the fixing module 1. This connection structure makes it easier to replace the main body 21. When different specifications of columns 3 are needed, simply loosen the fasteners 11 connecting the fixing plates 12 on both sides to the piling machine, and separate or snap the snap-fit ​​part 25 from the slot 13 to achieve the replacement of the main body 21 of different specifications. Finally, tighten the fasteners 11 to carry out the piling operation. No complicated tools and operations are required, saving time and labor costs, and further improving the adaptability of the pile head to different columns 3.

[0062] Specifically, the slot portion 13 includes a first surface 131 and a second surface 132 arranged opposite each other in the vertical direction, and a first sidewall 133 and a second sidewall 134 arranged opposite each other in the horizontal direction. The first surface 131, the second surface 132, the first sidewall 133, and the second sidewall 134 together form the slot portion 13. When the engaging portion 25 engages with the slot portion 13, the first sidewall 133 and the second sidewall 134 respectively abut against the opposite sides of the engaging portion 25 to achieve a detachable connection between the piling module 2 and the fixing module 1. Furthermore, the distance between the first surface 131 and the second surface 132 is greater than or equal to the thickness of the engaging portion 25 to accommodate the thickness of piling modules 2 of different specifications.

[0063] See Figure 1 , Figure 2 ,and Figure 4 A reinforcing plate 14 is provided on the side of the two fixing plates 12 that are close to each other. The reinforcing plate 14 enhances the structural strength of the connection between the fixing plate 12 and the pile driver, improves the overall stability of the fixing module 1, and can better withstand the impact force transmitted by the pile driver during the pile driving process, preventing the fixing plate 12 from deforming due to force and affecting the connection stability between the pile head and the pile driver.

[0064] See Figure 1 , Figure 2 , Figure 4 and Figure 5 Each of the two fixing plates 12 has a laterally extending connecting part 15 at one end near the main body 21. A screw pair 16 is provided between the two connecting parts 15. A limiting cylinder 17 is symmetrically sleeved at both ends of the screw pair 16 near the two connecting parts 15 to limit the position of the pile driver hook. The limiting cylinder 17 can limit the position of the pile driver hook, prevent the hook from shifting during the pile driving process, and ensure the normal operation of the pile driver when hoisting the column 3.

[0065] A pile driver includes the aforementioned pile head. When installing the pile head, the fixing module 1 is first connected to both ends of the pile driver using fasteners 11. The strength and stability of the connection between the fixing module 1 and the pile driver are enhanced by reinforcing plates 14. At the same time, the pile driver hook is limited by the screw pair 16 between the connecting parts 15 and the limiting cylinder 17 to ensure the normal operation of the pile driver when hoisting the column 3.

[0066] When dealing with columns 3 of different specifications, the relative position and spacing of the limiting parts 22 on the main body 21 can be adjusted through the waist-shaped holes, and / or, different numbers or sizes of limiting parts 22 can be replaced to make the limiting parts 22 press against the web plate 31 and wing plate 32 of the column 3, so as to complete the rapid engagement of the column 3 with the pile head of the piling machine; when the type or specifications of the column 3 vary greatly, the corresponding specifications of the piling module 2 can be directly replaced to adapt to the column 3.

[0067] Through the above methods, the pile head of the piling machine and the column 3 of different specifications can be quickly matched, reducing the time for matching the pile head of the piling machine with the column 3 and changing tooling, and greatly improving the piling efficiency.

[0068] 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.
