Description

Technical Field

[0001] This utility model relates to the field of precast pile driving construction technology, specifically a precast pile angle correction device and a pile driver. Background Technology

[0002] Static pile driving is a commonly used pile driving method. It generally uses a static pile driver to apply pressure to the top or side wall of the precast pile to smoothly press the pile into the foundation.

[0003] Existing static pressure pile drivers can only move horizontally or longitudinally on the ground, and cannot make small adjustments to the angle and position of precast piles on the horizontal plane. This often results in discrepancies between the actual position of the precast pile after construction and the pre-set pile orientation. For underground pile walls, this can cause the transverse splicing surfaces of adjacent precast piles to not fit together, creating large gaps and failing to achieve a sealing and waterproofing effect, severely impacting the quality of pile foundation construction.

[0049] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] In this document, terms such as "upper," "lower," "inner," and "outer" are established based on the positional relationships shown in the accompanying drawings. Depending on the drawings, the corresponding positional relationships may also change. Therefore, they should not be interpreted as an absolute limitation on the scope of protection. Moreover, relational terms such as "first" and "second" are only used to distinguish one component from another that has the same name, and do not necessarily require or imply any such actual relationship or order between these components.

[0051] Example 1

[0052] Figure 1 is a schematic diagram showing that the pre-set construction position of the precast pile during pile driving construction mentioned in the background technology is inconsistent with the actual position of the precast pile after construction. A1 (solid box) is the pre-set construction position of the precast pile, and A2 (dashed box) is the actual position of the precast pile after construction. In this case, for underground pile walls, the transverse splicing surfaces of two adjacent precast piles cannot fit together, resulting in a large splicing gap and failing to achieve the sealing and water-stopping effect.

[0053] Figure 2 is a structural schematic diagram of a precast pile angle correction device disclosed in an embodiment of this utility model. Figure 3 This is a structural schematic diagram of a precast pile angle correction device disclosed in another embodiment of the present utility model. Figure 5 for Figure 3 An enlarged diagram of section C. Figure 6 This is a partial structural diagram of the base disclosed in an embodiment of the present utility model.

[0054] like Figures 2-3 , Figures 5-6 As shown, the precast pile angle correction device provided by this utility model is used to correct the angle of the precast pile during the precast pile driving construction process. It includes: a base 1, a movable part 2, and at least one driving component 3. The base 1 is provided with a vertical channel 11. The movable part 2 is at least partially rotatably inserted into the vertical channel 11. The movable part 2 can be equipped with a pile gripper 23, which is used to grip the precast pile. The driving component 3 is installed on the base 1 to drive the movable part 2 to deflect around the vertical axis, thereby correcting the horizontal angle deviation of the precast pile, ensuring that the precast pile is driven into the designated position, effectively improving the accuracy of the pile driving orientation, ensuring that the transverse splicing surfaces of two adjacent precast piles are completely fitted, and improving the sealing and water-stopping effect at the pile joint.

[0055] Furthermore, such as Figure 2 and Figure 3As shown, the base 1 includes a platform 12 and multiple (two or more) circumferentially surrounding vertical channels 11 arranged on the platform 12, with one end of the drive component 3 mounted on the platform 12 or the reaction frame 13. Further, to achieve precise control of the deflection angle of the movable part 2, the drive component 3 can be a telescopic rod. One end of the drive component 3 is hinged to the platform 12 or the reaction frame 13, and the other end is hinged to the movable part 2. Specifically, the drive component 3 is a cylinder or a hydraulic cylinder. Preferably, the drive component 3 is a hydraulic cylinder, which can provide a large thrust to overcome the resistance of the soil to the precast pile and adjust the deflection angle of the precast pile. The required deflection angle of the movable part 2 can be achieved by adjusting the extension length of the telescopic rod.

[0056] In addition to being a telescopic rod, the driving component 3 can also include a deflection power source mounted on the base 1, a deflection component mounted on the movable part 2, and a transmission connection between the deflection power source and the deflection component through a transmission structure. This allows the deflection power source to drive the deflection component to rotate, thereby enabling the movable part 2 to deflect around its own vertical central axis. The deflection power source can be a hydraulic motor or an electric motor, and the deflection component can be a rotating gear, a deflection shaft, etc. The transmission structure can be at least one or more of the following: a single gear, multiple meshing gear sets, a combination of gear and chain or belt drive, or a worm gear structure. Any transmission structure that can achieve the goal of driving the movable part to deflect at a certain angle is acceptable and is not limited to the transmission structures listed above.

[0057] Furthermore, the movable part 2 can deflect clockwise and / or counterclockwise around its own vertical central axis. As a preferred embodiment, the deflection angle range of the movable part 2 around clockwise or counterclockwise is 0°-5°. It can be understood that the deflection angle range of the movable part 2 is determined according to the deviation of the precast pile position in the actual pile driving construction. As long as the position of the precast pile can be corrected, it is acceptable. In other implementations, the deflection angle range of the movable part can be appropriately adjusted, not limited to 0°-5°.

[0058] like Figure 3 As shown, the number of driving components 3 can be one, two, three, or more, depending on actual needs. Multiple driving components 3 are preferably spaced apart around the movable part 2. In this embodiment, four driving components 3 work together to drive the movable part 2 to rotate smoothly, thereby adjusting the angle of the movable part 2 and the precast pile, correcting the position of the precast pile to completely coincide with the preset pile position. The four driving components 3 can be set at the same height, or at least some of them can be spaced apart vertically, as long as their coordinated actions achieve the deflection of the movable part 2.

[0059] Figure 7 is a schematic diagram of the precast pile angle correction device disclosed in this embodiment of the present invention without the installation of the movable part. Figure 8 This is a schematic diagram of the structure of the guide frame disclosed in the embodiment of this utility model.

[0060] Furthermore, such as Figures 7-8 As shown, the movable part 2 includes a guide frame 22, which includes two or more guide posts 221 spaced apart circumferentially, and at least one ring beam 222 circumferentially clamped to the outside of the guide posts 221. A pile gripper 23 can be installed in the space between the guide posts 221. The guide posts 221 extend vertically and guide the pile gripper 23 to move vertically up and down. In this embodiment, the movable part 2 includes two ring beams 222 spaced apart along the length of the guide posts 221. Each ring beam 222 has two drive members 3 spaced apart, and the two drive members 3 on each ring beam 222 are arranged opposite to each other. The two ring beams 222 enhance the overall rigidity and structural strength of the movable part 2.

[0061] Furthermore, guide rails 2211 are provided on the guide post 221 (such as...). Figure 8 The pile driver 23 is driven by the external pile-driving cylinder 6 to slide vertically along the guide rail 2211 to perform pile driving operations, which improves the accuracy of pile driving.

[0062] In order to make the active part 2 follow a preset trajectory (such as...) Figure 9 (As shown by the dashed circle) deflection, improving the accuracy of the deflection of the movable part 2, a deflection guide assembly 4 is provided between the ring beam 222 and the reaction frame 13, specifically, as... Figure 4 As shown, the deflection guide assembly 4 includes: a guide roller 41 disposed on one of the reaction frame 13 and the ring beam 222, and an arc-shaped guide surface 42 disposed on the other of the reaction frame 13 and the ring beam 222. The arc-shaped guide surface 4 and the guide roller 41 roll in cooperation to guide the movable part 2 to deflect around its own vertical central axis, so that the movable part 2 deflects along a preset trajectory to accurately correct the horizontal angle deviation of the precast pile.

[0063] like Figure 3 and Figure 7 As shown, preferably, there are multiple deflection guide components 4, which are spaced apart and distributed at the corners of the outer wall of the ring beam 222. When the driving member 3 drives the movable part 2 to deflect, the multiple deflection guide components 4 cooperate with each other to guide the movable part 2 to deflect around the vertical axis. In other embodiments, the number of deflection guide components 4 can be one or more, and the specific number is not limited. The specific position of the deflection guide components 4 can be set according to actual needs, and is not limited to being set at the corners of the outer wall of the ring beam 222.

[0064] like Figure 4 and Figure 11As shown, in order to adjust the position of the guide roller 41 and the arc-shaped guide surface 42 according to factors such as production errors and installation errors, so that the guide roller 41 abuts against the arc-shaped guide surface 42 and ensures that the actual deflection trajectory of the moving part 2 conforms to the preset deflection trajectory, the reaction frame 13 is equipped with a lateral adjustment rod 14. One end of the lateral adjustment rod 14 near the vertical channel 11 is connected to the guide roller 41. Specifically, the lateral adjustment rod 14 is provided with a mounting shaft 16, and the guide roller 41 is sleeved on the mounting shaft 16. The other end of the lateral adjustment rod 14 is connected to the reaction frame 13. At least part of the rod body of the lateral adjustment rod 14 is a telescopic rod structure or an extension rod structure. By adjusting the axial length of the lateral adjustment rod 14 itself, the lateral distance between the guide roller 41 and the arc-shaped guide surface 42 is adjusted so that the guide roller 41 abuts against the arc-shaped guide surface 42. Alternatively, the lateral adjustment rod 14 has multiple connection points along its length that are connected to the reaction frame 13. These connection points can be located on the lateral adjustment rod 14 away from the vertical channel 11. The guide roller 41 is positioned at one end or the middle of the lateral adjustment rod 14, depending on the specific needs. The axial length of the lateral adjustment rod 14 extending beyond the reaction frame 13 is adjusted, thereby adjusting the lateral distance between the guide roller 41 and the arc-shaped guide surface 42, so that the guide roller 41 abuts against the arc-shaped guide surface 42. In other embodiments, the lateral adjustment rod 14 may not be provided; the guide roller 41 is mounted to the reaction frame 13 or the ring beam 222 via the mounting shaft 16.

[0065] Preferably, the central angle of the arc-shaped guide surface 42 is greater than the preset deflection angle of the movable part 2, so as to ensure that the guide roller 41 always abuts against the arc-shaped guide surface 42 within the deflection angle range of the movable part 2, thereby better guiding the deflection movement of the movable part 2.

[0066] Preferably, the guide roller 41 and / or the arc-shaped guide surface 42 are provided with a wear-resistant layer or wear-resistant pad (not shown in the figure) to extend the service life of the guide roller 41 and / or the arc-shaped guide surface 42.

[0067] Preferably, both the outer surface of the guide roller 41 and the arc-shaped guide surface 42 are provided with teeth (not shown in the figure). The guide roller 41 and the arc-shaped guide surface 42 mesh with each other through the teeth. The teeth enable the guide roller 41 and the arc-shaped guide surface 42 to mesh stably. Preferably, when the outer contour dimension of the arc-shaped guide surface is fixed, the number of teeth is increased as much as possible to reduce the tooth width, thereby improving the accuracy of adjusting the deflection angle.

[0068] Figure 3 is a structural schematic diagram of a precast pile angle correction device disclosed in another embodiment of this utility model. Figure 10 This is a schematic diagram of the structure of the clamping unit 231 disclosed in the embodiment of this utility model.

[0069] like Figure 3 , Figure 10 As shown, to achieve stable clamping of precast piles and improve the accuracy of pile driving, the pile clamp 23 includes two or more clamping units 231, each clamping unit 231 clamping different sections along the length of the same precast pile. In other embodiments, there may be only one clamping unit 231. At least one clamping unit 231 is connected to an external pile driving cylinder 6, which drives the clamping unit 231 to slide along the guide post 221; wherein, the clamping unit 231 includes a hollow clamping head body 2311, a plurality of clamping blocks 2312 arranged sequentially along the inner circumference of the clamping head body 2311, and a plurality of pile clamping cylinders (not labeled) installed on the clamping head body 2311. Each pile clamping cylinder is connected to a clamping block 2312, and the inner walls of the plurality of clamping blocks 2312 together form a clamping space for accommodating the precast pile. In the embodiments of this application, as shown... Figure 10 As shown, the cross-sectional shape of the clamping space is polygonal, which is suitable for precast piles with polygonal cross-sectional shapes, such as triangular, quadrilateral, pentagonal, octagonal, cross-shaped, I-shaped, etc. This allows the clamping unit 231 to clamp the precast pile body at multiple positions along the circumference, and the clamping force on the precast pile body along the circumference is evenly distributed, so as to achieve the purpose of stably clamping the precast pile.

[0072] In this embodiment, the parts that are the same as in Embodiment 1 are given the same reference numerals, and the same text descriptions are omitted.

[0073] Compared to Embodiment 1, the precast pile angle correction device provided in this embodiment has the following structural design differences:

[0074] like Figure 5 , Figure 12As shown, to constrain the vertical freedom of the movable part 2 and prevent it from swaying vertically during deflection, ensuring that the movable part 2 deflects only around its own vertical central axis, a vertical positioning component 15 is provided between the ring beam 222 and the base 1. The vertical positioning component 15 includes an abutment member 152 disposed on one of the base 1 and the ring beam 222, and an abutment surface disposed on the other of the base 1 and the ring beam 222, with the abutment member 152 and the abutment surface in vertical contact. The vertical positioning component 15 can be disposed between the reaction frame 13 and the ring beam 222 or between the platform 12 and the ring beam 222. The abutment 152 can be any one of an abutment block, a roller, or a ball. When the abutment 152 is an abutment block, the surface of the abutment block that contacts the abutment surface can be a flat surface or an arc surface. When the abutment 152 is a roller or a ball, the ring beam 222 and the base 1 are in rolling contact, and the moving part 2 deflects more smoothly relative to the base 1.

[0075] Preferably, in this embodiment, the abutment member 152 is an abutment roller 1521, with the abutment surface located at the top or bottom of the ring beam 222. The reaction frame 13 or platform 12 is equipped with a vertical adjustment rod 151, and the abutment roller 1521 is installed at one end of the vertical adjustment rod 151 near the ring beam 222. Specifically, the end of the vertical adjustment rod 151 near the ring beam 222 is connected to a mounting shaft 16, and the abutment roller 1521 is fitted onto the mounting shaft 16, thereby facilitating the installation of the abutment roller 1521 onto the reaction frame 13. Preferably, at least a portion of the vertical adjustment rod 151 is a telescopic rod structure or an extension rod structure. By adjusting the axial length of the vertical adjustment rod 151 itself, the vertical distance between the abutment roller 1521 and the abutment surface is adjusted, so that the abutment roller 1521 abuts against the abutment surface. Alternatively, the vertical adjustment rod 151 may have multiple connection points along its length that connect to the reaction frame 13 or platform 12. By adjusting the axial length of the vertical adjusting rod 151 extending from one end of the reaction frame 13, the vertical distance between the abutting roller 1521 and the abutting surface is adjusted, so that the abutting roller 1521 abuts against the abutting surface. In other embodiments, the vertical adjusting rod 151 may be omitted, and the abutting roller 1521 may be directly mounted to the reaction frame 13 or platform 12 via the mounting shaft 16.

[0076] Preferably, such as Figure 5As shown, two sets of vertical positioning components 15 are provided between the ring beam 222 and the base 1, respectively located on both sides of the ring beam 222 along the vertical direction, thereby restricting the upward and downward movement of the ring beam 222. Of course, vertical positioning components 15 can also be provided only between the top of the ring beam 222 and the base 1 or between the bottom of the ring beam 222 and the base 1, depending on the actual needs. When the vertical positioning component 15 is provided between the bottom of the ring beam 222 and the platform 12 or the reaction frame, the abutment roller 1521 is installed on the platform 12 or the reaction frame 13, and the outer peripheral surface of the abutment roller 1521 abuts against the bottom of the ring beam 222, or the abutment roller 1521 is installed on the bottom of the ring beam 222, and the outer peripheral surface of the abutment roller 1521 abuts against the platform 12 or the reaction frame 13, which serves to support the movable part 2 and make the deflection of the movable part 2 more flexible.

[0077] The abutment 152 can directly abut against the upper or lower surface of the ring beam 222, platform 12, or reaction frame 13, or the ring beam 222, platform 12, or reaction frame 13 can be provided with an abutment plate 5, and the abutment 152 abuts against the abutment plate 5. The abutment plate 5 can increase the structural strength of the ring beam 222, platform 12, or reaction frame 13, and at the same time, it is convenient to replace the abutment plate 5 when it is worn.

[0078] Example 3

[0079] In this embodiment, the parts that are the same as in Embodiment 1 are given the same reference numerals, and the same text descriptions are omitted.

[0081] Figure 14 This is a schematic diagram of another reaction frame and ring beam guiding fit disclosed in an embodiment of the present utility model;

[0082] Figure 15 for Figure 13 An enlarged schematic diagram of part D in the middle.

[0083] Compared to Embodiment 1, the precast pile angle correction device provided in this embodiment has the following structural design differences: mainly in the structure of the deflection guide component 4, such as... Figure 14As shown, the deflection guide assembly 4 of the first structure provided in this embodiment includes a first arc-shaped surface 43 disposed on the reaction frame 13 and a second arc-shaped surface 44 disposed on the ring beam 222. The second arc-shaped surface 44 protrudes towards the first arc-shaped surface 43. The centers of the corresponding circles of the first arc-shaped surface 43 and the second arc-shaped surface 44 coincide and their curvatures match. When the driving member 3 drives the movable part 2 to deflect, the second arc-shaped surface 44 slides along the first arc-shaped surface 43 to guide the movable part 2 to deflect around its own vertical central axis. The first arc-shaped surface 43 can be formed by recessing the surface of the reaction frame 13 towards the vertical channel 11, or an arc plate with the first arc-shaped surface 43 can be fixedly installed on the reaction frame 13. Similarly, the second arc-shaped surface 44 can be formed by recessing the surface of the ring beam 222 towards the vertical channel 11, or an arc plate with the second arc-shaped surface 44 can be fixedly installed on the ring beam 222.

[0084] Preferably, the central angle of the first arc surface 43 is greater than the central angle of the second arc surface 44, so that the second arc surface 44 and the first arc surface 43 always remain in contact during the deflection process of the movable part 2, thereby better guiding the deflection movement of the movable part 2.

[0085] like Figure 13 , Figure 15 As shown, the deflection guide assembly 4 of the second structure provided in this embodiment includes an arc-shaped guide surface 45 disposed on the reaction frame 13 and an abutment element 46 disposed on the ring beam 222. The side of the abutment element 46 facing the arc-shaped guide surface 45 has an arc surface. The abutment element 46 can be integrally formed by protruding from the ring beam 222 towards the arc-shaped guide surface, or the abutment element 46 can be fixedly installed on the ring beam 222. When the driving member 3 drives the movable part 2 to deflect, the abutment element 46 slides along the arc-shaped guide surface to guide the movable part 2 to deflect around its own vertical central axis. The center of the arc-shaped guide surface is on the vertical central axis of the movable part 2 itself. The arc-shaped guide surface can be formed by recessing the surface of the reaction frame 13 towards the vertical channel 11, or an arc-shaped plate with an arc-shaped guide surface can be fixedly installed on the reaction frame 13.

[0086] Example 4

[0087] In this embodiment, the parts that are the same as those in Embodiments 1-3 are given the same reference numerals, and the same text descriptions are omitted.

[0088] This embodiment provides a pile driver, including a precast pile angle correction device as described in any of embodiments 1-3, a pile driving cylinder 6, and a traveling mechanism (not shown). The pile driving cylinder 6 is installed on the top of the movable part 2 and connected to the pile gripper 23. The traveling mechanism is connected to the base 1 and is located at the bottom of the base 1 to allow the precast pile angle correction device to move on the ground. Specifically, the cylinder body of the pile driving cylinder 6 is fixed on the top of the guide column 221 of the guide frame 22 or on the ring beam 222. The extended end of the pile driving cylinder 6 is connected to the top of the clamp body 2311. When the pile gripper 23 clamps the precast pile, the pile driving cylinder 6 drives the pile gripper 23 to move vertically along the guide column 221, thereby driving the precast pile clamped by the pile gripper 23 to perform pile driving operations. The traveling mechanism can adopt walking, tracked, wheeled, tracked-wheel hybrid, or rail-based structures, all of which are existing technologies and will not be elaborated here. Walking mechanism is preferred because it is highly flexible and can move and operate flexibly in various terrains and environments. It is suitable for various construction sites and is easy to operate and maintain.

[0089] Preferably, to automate the pile driving construction, the pile driving cylinder 6, the pile gripper 23, and the drive unit 3 are each electrically connected to an external controller. During the pile driving process, the controller (not shown) controls the pile gripper 23 to clamp the precast pile, and then controls the external pile driving cylinder 6 to drive the clamping unit 231 to move vertically along the guide column 221 to drive the precast pile into the soil. When the position of the precast pile deviates, the controller sends a command to the drive unit 3 to extend outward or retract inward by a set length to drive the movable part 2 to deflect horizontally by a set angle along its own vertical central axis. When the position of the precast pile is adjusted to completely coincide with the preset pile position, the controller sends a command to the drive unit 3 to stop extending and retracting, thereby completing the position adjustment of the precast pile.

[0090] 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.
