Description

A piling auxiliary robotic arm for photovoltaic piling Technical Field

[0001] This invention relates to the field of photovoltaic pile installation technology, specifically to a pile auxiliary robotic arm for photovoltaic pile driving. Background Technology

[0002] Photovoltaic pile projects have advantages such as directly converting solar energy into electrical energy using solar cells, reliability, stability, long lifespan, and easy installation and maintenance. Photovoltaic installation requires piling, usually done using a piling machine, to drive the photovoltaic piles into the installation area. A photovoltaic pile component is a power generation device that generates direct current when exposed to sunlight. It is composed of thin solid photovoltaic cells made almost entirely of semiconductor materials. Because it has no moving parts, it can operate for a long time without any wear and tear. Professional engineering construction is limited by land and photovoltaic resources. Ground-mounted photovoltaic power stations are often planned in sites with different terrain types such as tidal flats, hills, Gobi Desert, and desert. When constructing in such areas, it is necessary to pre-plan the photovoltaic ground piles to reduce the impact of large terrain undulations on the installation effect of the photovoltaic power generation project. The accurate installation of photovoltaic ground piles determines the service life of the photovoltaic project.

[0003] In the prior art, publication number "CN205100217U" discloses a photovoltaic piling machine, including a walking mechanism, a piling mechanism mounted on the walking mechanism, and a measuring mechanism for measuring the piling points of the piling mechanism. The measuring mechanism transmits the measured signals to the control unit for analysis and processing, and adjusts the operating state of the walking mechanism based on the analysis and processing results. The measuring mechanism measures the geographical location of the piling point, compares and analyzes the offset between the piling point and the predetermined piling point, and adjusts the walking mechanism to move according to the analysis results, so that the piling point coincides with the predetermined piling point, ensuring that the driven piles are located on the same straight line.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] In the aforementioned devices and existing technologies, the piling effect is improved by calibrating the deviation between the piling point and the preset piling point. However, during the piling process, the pile body continuously enters the pile hole under the hammer of the piling machine. When photovoltaic pile construction is carried out on tidal flats, the ground on the tidal flats is relatively soft. When the pile body is inserted into the pile hole during the hammering process, the end of the pile body lacks external support, making it impossible for the end of the pile body to maintain the calibrated position and insert into the pile hole. As the pile body is continuously subjected to force, it is easy for the photovoltaic pile body to tilt, thereby causing the pile body to deviate from the preset position of the pile hole. After deviating from the pile hole, the pile body collides with the inside of the pile hole, which can easily cause the pile body to break. The damaged pile body will break into the preset hole. The broken pile body is not easy to remove from the preset pile hole, which increases the construction cost of photovoltaic projects and also increases the construction difficulty of photovoltaic projects.

[0019] Preferably, the positioning top plate has a strip-shaped groove, and one of the second electro-hydraulic telescopic rods is installed inside the strip-shaped groove.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. Before construction, the operator first installs the positioning base plate on the top of the pile hole, so that the first positioning hole on the positioning base plate is concentric with the pile hole. The pile body is lifted by the chuck and inserted into the pile positioning unit. The pile positioning unit can calibrate the end of the inserted pile body, so that the pile body is correctly inserted into the second positioning hole, thereby ensuring that the pile body remains perpendicular to the first positioning hole under the hammer of the pile driver.

[0022] 2. The pile body is vertically inserted into the first positioning hole. As the pile body descends, it remains vertically lowered under the guidance of the pile body guiding unit. At the same time, the pile body guiding unit supports the outside of the pile body to keep it stable during the descent. Under the support of the pile body, the pile body guiding unit will squeeze the protrusion. The protrusion pushes the annular plate to squeeze the first telescopic airbag, so that the gas in the first telescopic airbag is injected into the telescopic cylinder through the conduit. The output end of the telescopic cylinder extends and pushes the pile positioning unit to move upward, further allowing the pile positioning unit to stably calibrate and support the upper end of the pile body.

[0023] 3. While the annular plate is compressing the first telescopic airbag, it drives the inclined block to descend. The two sides of the inclined block compress the connecting rod and the baffle respectively. When the inclined block compresses the connecting rod, it will push the connecting rod to move. When the connecting rod moves, it will push the stabilizing block to unfold, increasing the contact area between the positioning base plate and the external installation plane, maintaining the overall stability of the device, and facilitating the improvement of the pile driving stability effect.

[0024] 4. When the inclined block presses against the baffle, the inclined block will push the baffle and the insert rod installed on one side of the baffle to move. During the movement of the insert rod, it will push the second ball bearing to fit against the surface of the pile body. The ring-shaped second ball bearing will provide stable calibration support for the lower end of the pile body, further ensuring that the pile body is accurately inserted into the pile hole during the pile driving process.

[0025] In the process of using this invention, before construction, the operator first installs the positioning base plate on the top of the external pile hole, and makes the first positioning hole on the positioning base plate concentric with the pile hole. The pile body is lifted by the chuck and inserted into the top of the positioning platform. Since the third positioning hole where the chuck is located is also concentric with the first positioning hole, the pile body and the pile hole are concentric at this time.

[0026] The pile is inserted into the sleeve by the chuck and then into the center area of ​​multiple support blocks. The operator then releases the chuck, and the pile is continuously lowered into the first positioning hole by the rollers. During the descent, the pile is continuously squeezed by the rollers, and the support blocks are squeezed down to squeeze the protrusions. The protrusions drive the annular plate to squeeze the first telescopic air bladder, so that the gas inside the first telescopic air bladder is injected into the pneumatic telescopic rod. After the pneumatic telescopic rod is injected with gas, the output end of the pneumatic telescopic rod extends and pushes the installation block to move upward, thereby stabilizing and calibrating the upper end of the pile.

[0027] During the process of the support block being squeezed, one side of the support block will push the squeezing block to squeeze the output end of the telescopic cylinder, so that the gas inside the telescopic cylinder is injected into the second telescopic airbag through the air supply hose. When the card block is pushed by the inflation of the second telescopic airbag to stick to the surface of the pile, multiple sets of card blocks are arranged in a ring, so that the outside of the pile can be effectively and stably supported.

[0028] The ring plate, when squeezed, pushes the inclined block down, which in turn pushes the baffle and the rod installed on one side of the baffle to move. During the movement of the rod, the second ball bearings are pushed to fit against the surface of the pile. The ring-shaped second ball bearings provide stable calibration support for the lower end of the pile, further ensuring that the pile is accurately inserted into the external pile hole during the pile driving process.

[0029] When the inclined block presses against the connecting rod, it will push the connecting rod to move. When the connecting rod moves, it will push the stabilizing block to unfold, increasing the contact area between the positioning base plate and the external mounting surface, maintaining the overall stability of the device, and facilitating the improvement of the pile driving stability effect. When the inclined block separates from the connecting rod, the return spring will push the retaining ring to reset, so that the connecting rod is reinserted into the through hole area. As the connecting rod moves, it drives the stabilizing block to be inserted into the receiving groove. Attached Figure Description

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please refer to Figures 1-11. This invention provides a technical solution: a pile body auxiliary robotic arm for photovoltaic piling.

[0044] Example 1: A piling auxiliary robotic arm for photovoltaic piling includes a positioning platform 1, a positioning base plate 2, a drive tube 6, and a lifting frame 7. The positioning base plate 2 has a first positioning hole 21 on its surface, and the positioning platform 1 has a second positioning hole 11 on its surface. The positioning platform 1 is mounted on top of the positioning base plate 2. The drive tube 6 is mounted on top of the positioning platform 1, and a drive motor 61 is installed inside the drive tube 6. The lifting frame 7 is mounted at the output end of the drive motor 61. The lifting frame 7 has a mounting groove 71 on its surface, and a first electro-hydraulic telescopic rod 73 is installed inside the mounting groove 71. A push plate 72 is installed at the output end of the first electro-hydraulic telescopic rod 73. A positioning top plate 8 is provided on one side, and a third positioning hole 81 is provided on the surface of the positioning top plate 8. A chuck 84 is installed on both sides of the third positioning hole 81. A second electro-hydraulic telescopic rod 83 is installed on the outside of the positioning top plate 8. The output end of the second electro-hydraulic telescopic rod 83 passes through the positioning top plate 8 and connects to one side of the chuck 84. The second positioning hole 11 and the third positioning hole 81 are both concentrically arranged with the first positioning hole 21. A strip groove 82 is formed on the positioning top plate 8, and one of the second electro-hydraulic telescopic rods 83 is installed inside the strip groove 82. In this embodiment, the positioning bottom plate 2 is vertically installed on the surface of the external pile hole, and the surface of the positioning bottom plate 2... The first positioning hole 21 is concentric with the external pile hole. The second positioning hole 11 and the third positioning hole 81 are both concentric with the first positioning hole 21. This ensures that the pile body is always perpendicular to the external pile hole during installation. During use, the drive motor 61 inside the drive tube 6 drives the lifting frame 7 to deflect, thereby clamping and installing the external pile body through the second electro-hydraulic telescopic rod 83 and the chuck 84. After installation, the pile body is raised and lowered by driving the first electro-hydraulic telescopic rod 73, and the chuck 84 inserts the pile body into the sleeve 3 and into the center area of ​​multiple sets of support blocks 44. After the operator releases the chuck 84, the pile body is continuously lowered into the first positioning hole 21 by the roller 46. The second electro-hydraulic telescopic rod 83 installed inside the strip groove 82 is symmetrically arranged with the second electro-hydraulic telescopic rod 83 installed on one side of the positioning top plate 8, ensuring the clamping effect of the adjacent chuck 84 on both sides of the pile body. The first positioning hole 21 is opened in the center area of ​​the surface of the positioning base plate 2 to ensure the average force on the bottom of the positioning base plate 2 and reduce the shaking of the positioning base plate 2. The second positioning hole 11 is opened in the center area of ​​the surface of the positioning platform 1 to ensure the average force on the bottom of the positioning platform 1 and avoid the overall center of gravity of the device being unstable.

[0045] The positioning base plate 2 has storage slots 23 on both sides. A connecting hole 211 is provided in the area where the first positioning hole 21 connects with the storage slot 23. A stabilizing block 22 is provided inside the storage slot 23. A connecting rod 24 is installed on one end of the stabilizing block 22 near the connecting hole 211. A retaining ring 241 is fixedly sleeved on one end of the connecting rod 24. One end of the connecting rod 24 passes through the connecting hole 211. A return spring 242 is movably sleeved on the surface of the connecting rod 24. One end of the return spring 242 is fixed to one side of the retaining ring 241. The other end of the return spring 242 is fixed to the inner wall of the storage slot 23 near the connecting hole 211. A groove 13 is provided on the inner wall of the second positioning hole 11 near the area of ​​the first positioning hole 21. A first telescopic airbag 14 is installed at the bottom of the groove 13. The upper surface of the first telescopic airbag 14... An annular plate 16 is installed on the surface. A wedge 161 is provided at the bottom of the annular plate 16, and a protrusion 17 is provided at the top of the annular plate 16. A conduit 141 is connected to one side of the first telescopic airbag 14. A telescopic cylinder 18 is installed on the inner wall of the second positioning hole 11. Air supply hoses 19 are connected to both sides of the telescopic cylinder 18. Recessed holes 12 are opened on both sides of the positioning platform 1. A pneumatic telescopic rod 121 is installed inside the recessed hole 12. A connecting groove 122 is opened at the bottom of the recessed hole 12, and the connecting groove 122 communicates with the groove 13. The conduit 141 passes through the connecting groove 122 and communicates with the bottom of the pneumatic telescopic rod 121. In this embodiment, the connecting hole 211 and the receiving groove 23 are set as two sets, wherein the connecting hole 211 corresponds to the two sets of mounting brackets 5 inside the first positioning hole 21. While the forming plate 16 compresses the first telescopic airbag 14, it drives the inclined block 161 to descend. The two sides of the inclined block 161 respectively compress the connecting rod 24 and the baffle 54. When the inclined block 161 compresses the connecting rod 24, it pushes the connecting rod 24 to move. When the connecting rod 24 moves, it pushes the stabilizing block 22 to unfold, increasing the contact area between the positioning base plate 2 and the external mounting plane, maintaining the overall stability of the device, and facilitating the improvement of the pile driving stability effect. When the inclined block 161 compresses the baffle 54, the inclined block 161 pushes the baffle 54 and the insert rod 51 installed on one side of the baffle 54 to move. During the movement of the insert rod 51, it pushes the second ball bearing 52 to fit against the pile surface. The annularly arranged second ball bearing 52 provides stable calibration support for the lower end of the pile, further ensuring the stability of the pile. During the piling process, the pneumatic telescopic rod 121 is accurately inserted into the external pile hole. When gas is injected into the pneumatic telescopic rod 121, the output end of the pneumatic telescopic rod 121 extends and pushes the mounting block 31 to move upward, thereby providing stable calibration support for the upper end of the pile. When the inclined block 161 disengages from the connecting rod 24, the return spring 242 pushes the retaining ring 241 to reset, so that the connecting rod 24 is reinserted into the through hole 56 area. As the connecting rod 24 moves, it drives the stabilizing block 22 to be inserted into the receiving groove 23. When the inclined block 161 squeezes the connecting rod 24, it pushes the connecting rod 24 to move. When the connecting rod 24 moves, it pushes the stabilizing block 22 to unfold, increasing the contact area between the positioning base plate 2 and the external mounting plane, maintaining the overall stability of the device, and facilitating the improvement of the piling stability effect.

[0046] The pile positioning unit is located at the top of the second positioning hole 11 and is used to cooperate with the chuck 84 to accurately place the pile body into the positioning platform 1.

[0047] The pile positioning unit includes a sleeve 3, with mounting blocks 31 on both sides of the sleeve 3. The bottom of the mounting blocks 31 is fixed to the output end of the pneumatic telescopic rod 121. An mounting plate 32 is provided on the inner wall of the sleeve 3. A second telescopic airbag 33 is provided on one side of the mounting plate 32. A locking block 34 is provided on the surface of the second telescopic airbag 33, and first ball bearings 35 are intermittently embedded in the locking block 34. One end of the air supply hose 19 is connected to the second telescopic airbag 33. In this embodiment, one side of the support block 44 pushes the compression block 47 to compress the output end of the telescopic cylinder 18, causing the gas inside the telescopic cylinder 18 to be injected into the second telescopic airbag 33 through the air supply hose 19. When the locking blocks 34 are pushed against the pile surface by the inflation of the second telescopic airbag 33, multiple sets of locking blocks 34 are arranged in a ring, providing effective and stable support to the outside of the pile. The mounting plate 32 is set at twelve intervals and is L-shaped, with the L-shaped mounting plates 32 connected end-to-end, allowing one side of the mounting plate 32 to support the second telescopic airbag 33. The second telescopic airbag 33 is covered on one side, and the adjacent mounting plate 32 can cover the other side of the second telescopic airbag 33, restricting the telescopic position of the second telescopic airbag 33. This allows the second telescopic airbag 33 to push the locking block 34 outward, while protecting the second telescopic airbag 33 and preventing collisions between adjacent second telescopic airbags 33. The bottom of the mounting block 31 is fixed to the output end of the pneumatic telescopic rod 121. When gas is injected into the pneumatic telescopic rod 121, the output end of the pneumatic telescopic rod 121 extends and pushes the mounting block 31 upward, thereby providing stable calibration support for the upper end of the pile. The locking block 34 is intermittently embedded with first ball bearings 35. When the locking block 34 is pushed against the surface of the pile by the second telescopic airbag 33, multiple sets of locking blocks 34 are arranged in a ring, so that the outside of the pile can be effectively stabilized and supported. At the same time, the first ball bearings 35 can guide the pile to insert into the central area of ​​multiple sets of support blocks 44. Each set of second telescopic airbags 33 is connected to two adjacent air supply hoses 19.

[0048] The pile guiding unit is installed inside the second positioning hole 11 to guide the end of the pile body placed inside the positioning platform 1, reduce the descent speed of the pile body, and make the end of the pile body aligned with the pile hole during the descent process.

[0049] The pile guiding unit includes a fixing block 4, which is installed on the inner wall of the second positioning hole 11. A fixing groove 41 is provided inside the fixing block 4, and a first rotating shaft 42 is fixed inside the fixing groove 41. A support block 44 is rotatably sleeved on the surface of the first rotating shaft 42. Torsion springs 43 are movably sleeved at both ends of the first rotating shaft 42. One end of the torsion spring 43 is fixed to the inner wall of the fixing groove 41, and the other end is fixed to one side of the support block 44. A support groove 441 is provided on the top of the support block 44. In this embodiment, two sets of torsion springs 43 are installed on each set of first rotating shafts 42. When the bottom end of the pile is inserted into the second positioning hole 11, the bottom of the pile first contacts the support block 44. The torsion springs 43 on the support block 44 push the rollers 46 on the support block 44 to fit against the bottom surface of the pile, and the torsion springs 43 maintain the support of the rollers 46 on the surface of the pile, thus effectively supporting the exterior of the pile. The pile provides stable support, and as the pile body continuously pushes the roller 46, it pushes the support block 44 to squeeze the telescopic cylinder 18, so that the gas inside the telescopic cylinder 18 is injected into the second telescopic airbag 33 through the air supply hose 19. The second telescopic airbag 33 pushes the locking block 34 to move outward, while protecting the second telescopic airbag 33 and preventing collisions between adjacent second telescopic airbags 33. The bottom of the mounting block 31 is fixed to the output end of the pneumatic telescopic rod 121. When gas is injected into the pneumatic telescopic rod 121, the output end of the pneumatic telescopic rod 121 extends and pushes the mounting block 31 to move upward, thereby providing stable calibration support for the upper end of the pile body. The locking block 34 is intermittently embedded with the first ball 35. When the locking block 34 is pushed by the second telescopic airbag 33 and adheres to the surface of the pile body, multiple sets of locking blocks 34 are arranged in a ring, so that the outside of the pile body can be effectively stabilized.

[0050] A second rotating shaft 45 is installed inside the support groove 441. A roller 46 is rotatably sleeved on the surface of the second rotating shaft 45. A wear-resistant mesh layer 461 is sleeved on the surface of the roller 46. A pressing block 47 is provided at the bottom of the support block 44. The pressing block 47 is in active contact with the output end of the telescopic cylinder 18. A smooth convex surface 48 is provided at the end of the support block 44 away from the first rotating shaft 42. The smooth convex surface 48 is in active contact with the protrusion 17. In this embodiment, the setting of the wear-resistant mesh layer 461 can reduce the wear of the contact area between the roller 46 and the pile body, and at the same time reduce the falling speed of the pile body, so that the pile body can be accurately inserted into the first positioning hole 21. When the pile body is detached from the support block 44, the torsion spring 43 can push the support block 44 to return to the initial state. The support block 44 continuously presses the protrusion 17 under the pressure of the pile body. Due to the smooth convex surface 48 at the bottom of the support block 44, the support block 44 will continuously push the protrusion 17 to press the first telescopic airbag 14. The gas inside the first telescopic airbag 14 Gas is injected into the pneumatic telescopic rod 121 through the conduit 141, which in turn pushes the output end of the pneumatic telescopic rod 121 to extend. When gas is injected into the pneumatic telescopic rod 121, the output end of the pneumatic telescopic rod 121 extends and pushes the mounting block 31 to move upward, thereby providing stable calibration support for the upper end of the pile. The second telescopic airbag 33 pushes the locking block 34 to move outward, while protecting the second telescopic airbag 33 and preventing collisions between adjacent second telescopic airbags 33. The bottom of the mounting block 31 is fixed to the output end of the pneumatic telescopic rod 121. When gas is injected into the pneumatic telescopic rod 121, the output end of the pneumatic telescopic rod 121 extends and pushes the mounting block 31 to move upward, thereby providing stable calibration support for the upper end of the pile. The locking block 34 is intermittently embedded with first ball bearings 35. When the locking block 34 is pushed by the second telescopic airbag 33 and adheres to the surface of the pile, multiple sets of locking blocks 34 are arranged in a ring, so that the outside of the pile can be effectively stabilized and supported.

[0051] Example 2:

[0052] Based on Embodiment 1, this embodiment considers that when the pile is inserted into the pile hole for pile driving, when the outside of the pile is stably supported, the pile can be inserted into the pile hole. During the hammering process of the external press machine, the pile will vibrate. If the bottom insertion area of ​​the pile lacks a pile holding unit, the pile will be inserted into the pile hole in a deviated state, and then collide with the inside of the pile hole, causing the pile to break. Therefore, in this embodiment, a pile holding unit is provided to ensure that the end of the pile can still be inserted into the pile hole in a normal state during the hammering process of the press machine, thus ensuring the pile driving effect.

[0053] The pile holding unit is installed inside the first positioning hole 21 and is used to hold the bottom end of the pile inserted into the first positioning hole 21 so that the pile maintains an accurate position when it is continuously driven into the pile hole.

[0054] The pile retaining unit includes a mounting frame 5, which is spaced in several groups. These groups of mounting frames 5 are installed on the inner wall of the first positioning hole 21. A through groove 55 is provided at the bottom of each mounting frame 5. One side of each group of mounting frames 5 has a through hole 56 communicating with the connecting hole 211. One end of a connecting rod 24 is inserted into the mounting frame 5. A sliding insert rod 51 is installed through one side of the mounting frame 5. A baffle 54 is installed at one end of the insert rod 51. An inclined block 161 makes movable contact with the connecting rod 24 and the baffle 54. A buffer spring 53 is movably sleeved on the surface of the insert rod 51. One end of the buffer spring 53 is connected to the mounting frame 5. The side is fixed, and the other end of the buffer spring 53 is fixed to one side of the baffle 54. The end of the insertion rod 51 is rolled and embedded with a second ball bearing 52. In this embodiment, when gas is injected into the pneumatic telescopic rod 121, the output end of the pneumatic telescopic rod 121 extends and pushes the mounting block 31 to move upward, thereby providing stable calibration support for the upper end of the pile. The locking block 34 is rolled and embedded with a first ball bearing 35 at intervals. When the locking block 34 is pushed by the second telescopic airbag 33 and adheres to the surface of the pile, multiple sets of locking blocks 34 are arranged in a ring, so that the outside of the pile can be effectively stabilized and supported. Mounting frame The mounting brackets 5 and support blocks 44 are arranged in twelve groups at intervals, with each group corresponding to a support block 44. Two sets of mounting brackets 5 have through holes 56 that connect to the connecting holes 211. This allows the connecting rod 24 to be inserted into the internal area of ​​the two sets of mounting brackets 5 through the through holes 56 and the connecting holes 211. When the inclined block 161 presses against the baffle 54, the inclined block 161 pushes the baffle 54 and the insert rod 51 installed on one side of the baffle 54 to move. During the movement of the insert rod 51, it pushes the second ball bearing 52 to adhere to the surface of the pile body. The annularly arranged second ball bearing 52 will impact the lower end of the pile body. Stable calibration support is provided to further ensure that the pile body is accurately inserted into the external pile hole during the pile driving process. When the inclined block 161 squeezes the connecting rod 24, it will push the connecting rod 24 to move. When the connecting rod 24 moves, it will push the stabilizing block 22 to unfold, increasing the contact area between the positioning base plate 2 and the external mounting plane, maintaining the overall stability of the device, and facilitating the improvement of the pile driving stability effect. When the inclined block 161 is separated from the connecting rod 24, the return spring 242 will push the retaining ring 241 to reset, so that the connecting rod 24 is reinserted into the through hole 56 area. As the connecting rod 24 moves, it drives the stabilizing block 22 to be inserted into the storage groove 23.

[0055] Working principle: During the use of this device, before construction, the operator first installs the positioning base plate 2 on the top of the external pile hole, and makes the first positioning hole 21 on the positioning base plate 2 concentric with the pile hole. The pile body is lifted by the chuck 84 and inserted into the top of the positioning platform 1. Since the third positioning hole 81 where the chuck 84 is located is also concentric with the first positioning hole 21, the pile body and the pile hole are concentric at this time.

[0056] The pile body is inserted into the sleeve 3 under the transport of the chuck 84 and inserted into the central area of ​​multiple sets of support blocks 44. Then, the operator releases the chuck 84, and the pile body is continuously lowered into the first positioning hole 21 under the transport of the roller 46. During the descent, the pile body is continuously squeezed by the roller 46. The support block 44 is squeezed down and squeezes the protrusion 17. The protrusion 17 drives the annular plate 16 to squeeze the first telescopic airbag 14, so that the gas inside the first telescopic airbag 14 is injected into the pneumatic telescopic rod 121. After the gas is injected into the pneumatic telescopic rod 121, the output end of the pneumatic telescopic rod 121 extends and pushes the mounting block 31 to move upward, thereby stabilizing and calibrating the upper end of the pile body.

[0057] During the process of the support block 44 being squeezed, one side of the support block 44 will push the squeezing block 47 to squeeze the output end of the telescopic cylinder 18, so that the gas inside the telescopic cylinder 18 is injected into the second telescopic airbag 33 through the air supply hose 19. When the locking block 34 is pushed by the inflation of the second telescopic airbag 33 to adhere to the surface of the pile, multiple sets of locking blocks 34 are arranged in a ring, so that the outside of the pile can be effectively and stably supported.

[0058] When the annular plate 16 is squeezed, it will push the inclined block 161 down. The inclined block 161 will push the baffle 54 and the insert rod 51 installed on one side of the baffle 54 to move. During the movement of the insert rod 51, it will push the second ball 52 to fit against the surface of the pile body. The annularly arranged second ball 52 will provide stable calibration support for the lower end of the pile body, further ensuring that the pile body is accurately inserted into the external pile hole during the pile driving process.

[0059] When the inclined block 161 presses against the connecting rod 24, it will push the connecting rod 24 to move. When the connecting rod 24 moves, it will push the stabilizing block 22 to unfold, increasing the contact area between the positioning base plate 2 and the external mounting plane, maintaining the overall stability of the device, and facilitating the improvement of the pile driving stability effect. When the inclined block 161 disengages from the connecting rod 24, the return spring 242 will push the retaining ring 241 to reset, so that the connecting rod 24 is reinserted into the through hole 56 area. As the connecting rod 24 moves, it drives the stabilizing block 22 to be inserted into the storage groove 23.
