Description

Technical Field

[0001] This application relates to the field of pile driving, and in particular to a small automatic pile driving device. Background Technology

[0002] Precast piles are piles of various materials and forms (such as wooden piles, concrete square piles, prestressed concrete pipe piles, steel piles, etc.) made in factories or on construction sites. They are driven, pressed, or vibrated into the soil using pile driving equipment, which can reduce the settlement and deformation of buildings.

[0003] Currently, during piling operations, construction companies need to bring a large amount of related equipment to the site to install pile frames before driving the piles sequentially. After piling is completed, the pile frames are dismantled. However, in the construction of small piles, in order to save on construction costs, some small piles are driven manually by workers. This easily leads to pile misalignment, resulting in poor piling efficiency and a lot of dust at the construction site, causing dust pollution during the piling process and affecting the physical and mental health of the construction workers. Summary of the Invention

[0004] In order to improve the accuracy of pile driving and reduce the impact of dust on the health of workers, this application provides a small automatic pile driving device.

[0005] The small-scale automatic pile driving device provided in this application adopts the following technical solution: A small automatic pile driving device includes a base, a pile driving mechanism, a limiting mechanism, and a dust suppression mechanism; The piling mechanism includes a lifting plate slidably mounted on a base, a driving assembly for driving the lifting plate to move up and down, a swing assembly mounted on the lifting plate, and a pile driving head connected to the swing assembly. The lifting plate slides in the vertical direction, and the swing assembly is used to drive the pile driving head to swing back and forth. The base has an clearance groove on the side near the pile head. The limiting mechanism includes two pile frames arranged opposite each other, a lifting component that drives the pile frames to slide, and a buffer component that is slidably connected between the two pile frames. The pile frames are vertically arranged and slidably connected to the side wall of the clearance groove. When the pile head swings, it strikes the buffer component. The dust suppression mechanism includes a water tank mounted on a lifting plate, a water pipe connected to the water tank, an atomizing nozzle connected to the water outlet of the water pipe, a squeezing assembly mounted on the water tank, and a one-way transmission assembly that drives the squeezing assembly to work. The squeezing assembly is used to squeeze the water inside the water tank to the atomizing nozzle for spraying. The one-way transmission assembly is located between the squeezing assembly and the swing assembly. When the swing assembly works, it drives the squeezing assembly to work synchronously.

[0006] By adopting the above technical solution, all the devices used for piling are integrated on a base. During piling, the base is moved to the construction position, the clearance groove is located above the pile pit, and the bottom end of the pile is inserted into the pile pit using a crane, so that the pile is located in the middle of the clearance groove and the bottom ends of the two pile frames are in contact with the ground. The buffer component is located at the top of the pile. Then, as the lifting plate slides down, the swing component drives the pile head to swing and strike the buffer component. The two pile frames limit the buffer component to ensure that the striking block can accurately strike the pile, which helps to prevent the pile from tilting and improves the accuracy and convenience of piling.

[0007] At the same time, when the swing component is working, it will drive the extrusion component to work synchronously. Each time the pile is driven, the extrusion component will squeeze the water inside the water tank and spray it out from the atomizing nozzle, which will reduce the dust and thus reduce the impact of dust on the health of the workers.

[0008] Furthermore, this application achieves linkage between the piling mechanism and the dust suppression mechanism by setting a one-way transmission component, eliminating the need to set a drive source on each mechanism, reducing the number of drive sources, thereby reducing power consumption, which helps to reduce costs and meet usage requirements.

[0009] Optionally, the drive assembly includes a U-shaped plate horizontally disposed above the lifting plate, a plurality of guide rods fixedly disposed between the U-shaped plate and the base, a lead screw rotatably connected between the U-shaped plate and the base, and a first motor for driving the lead screw to rotate. The guide rods slide through the lifting plate, and the lead screw is threadedly connected to the lifting plate.

[0010] By adopting the above technical solution, when the first motor drives the lead screw to rotate, the lifting plate moves in the vertical direction. At the same time, several guide rods guide and limit the movement of the lifting plate, making the movement of the lifting plate more stable.

[0011] Optionally, the swing assembly includes a fixed frame mounted on the lifting plate, a pile driving rod rotatably connected to the fixed frame at one end, a rotating shaft rotatably connected to the fixed frame, and a support rod fixedly connected to the rotating shaft. The pile driving head is fixedly connected to the other end of the pile driving rod. The rotating shaft is located below the pile driving rod. The axis of the rotating shaft is horizontally set and perpendicular to the length direction of the pile driving rod. The rotating shaft is driven by a second motor fixedly mounted on the lifting plate. The support rod is arranged radially along the rotating shaft. A roller is rotatably connected to the end of the support rod away from the rotating shaft. An inclined block is provided on the side of the pile driving rod near the lifting plate. When the pile driving rod is in a horizontal state, the inclined block is located between the rotating shaft and the pile driving head, and the inclined surface faces the rotating shaft. A diagonal brace is provided on the side of the fixed frame away from the pile head. A telescopic rod is hinged between the diagonal brace and the pile head. A first spring is sleeved on the outside of the telescopic rod, and the first spring is fixedly connected between the diagonal brace and the pile head.

[0012] By adopting the above technical solution, during pile driving, the second motor drives the rotating shaft to rotate, and the rotating shaft drives the support rod to rotate synchronously. During the rotation of the support rod, the roller abuts against the inclined surface on the inclined block, thereby lifting the end of the pile driving rod where the pile driving head is set. At this time, the first spring is in a compressed state.

[0013] When the roller leaves the inclined plane, the pile driving rod returns to its original position under the action of gravity and the elastic force of the first spring, thereby causing the pile driving head to strike the buffer assembly and realize pile driving.

[0014] Optionally, the buffer assembly includes a guide plate slidably disposed between two pile frames, a striking block disposed at the bottom of the guide plate, a plurality of limiting seats connected to the bottom of the lifting plate, and a sliding rod slidably passing through the limiting seats. The guide plate is horizontally disposed, and a fixed plate is fixedly disposed near each sliding rod. The sliding rod passes through the limiting seat from bottom to top and is fixedly connected to the fixed plate. A second spring is sleeved on the outside of the sliding rod, and the second spring is fixedly connected between the limiting seat and the fixed plate.

[0015] By adopting the above technical solution, the guide plate is slidably connected to the lifting plate, and the two are connected together by a second spring, so that the guide plate slides synchronously with the lifting plate during operation and can move relative to the lifting plate. When the pile head strikes the guide plate, the striking force is applied to the pile through the guide plate, causing the guide plate, the striking block and the pile to descend synchronously to achieve the pile driving effect. After one strike, the guide plate is reset under the elastic force of the second spring.

[0016] Optionally, the clearance groove is provided with a sliding groove on the side wall near the pile frame, and the pile frame is slidably connected inside the sliding groove. Each of the lifting components includes a second cylinder set on the base and a top plate connected to the piston rod of the second cylinder. The piston rod of the second cylinder moves in the vertical direction, and the top plate is fixedly connected to the top of the pile frame.

[0017] By adopting the above technical solution, when the second cylinder is working, it drives the pile frame to move in the vertical direction, so that the bottom ends of the two pile frames contact the ground during pile driving, which facilitates the guidance of the pile during pile driving. There is no need for manual installation and disassembly of the pile frame, saving the time spent on installation and disassembly of the pile frame, which not only reduces labor but also helps to reduce costs.

[0018] Optionally, the extrusion assembly includes a piston slidably disposed inside the water tank, a movable rod connected to the side of the piston away from the water pipe, a rack connected to the movable rod, and a gear rotatably disposed on the lifting plate. The gear meshes with the rack, and the one-way transmission assembly is used to drive the gear to rotate in one direction.

[0019] By adopting the above technical solution, when the gear rotates, it drives the rack to move, thereby causing the moving rod to push the piston to move inside the water tank, squeezing the water inside the water tank to flow into the atomizing nozzle, spraying it on the construction site to achieve the effect of dust reduction.

[0020] Optionally, one end of the pile driving rod is fixedly provided with a rotating rod, which is rotatably connected to the fixed frame. The one-way transmission assembly includes a central rod rotatably mounted on the lifting plate, a rotating cylinder coaxially rotatably sleeved outside the central rod, an inner ratchet coaxially mounted at one end of the rotating cylinder, a turntable disposed inside the inner ratchet, a pawl rotatably connected at one end to the turntable, and a spring piece fixedly connected at one end to the turntable. The rotating rod is arranged parallel to the central rod, and the rotating rod and the central rod are driven by a belt. The turntable is fixedly connected to the central rod, the rotating cylinder is coaxially fixedly connected to the gear, the other end of the pawl is engaged with the inner ratchet, and the other end of the spring piece abuts against the surface of the pawl. When the pile driving rod drives the pile driving head to lift upward, the pawl slides on the surface of the inner ratchet. When the pile driving rod drives the pile driving head to rotate downward, the pawl drives the inner ratchet to rotate synchronously, so that the gear rotates and drives the piston to squeeze water.

[0021] By adopting the above technical solution, the rotating rod and the central rod are connected by a belt drive. When the pile driving rod drives the pile driving head upward, the central rod drives the turntable to rotate synchronously. At this time, the pawl slides over the surface of the inner ratchet, and the inner ratchet is in a stationary state. When the pile driving rod drives the pile driving head downward, the pawl inserts into the gap between the two teeth of the inner ratchet, thereby driving the inner ratchet to rotate synchronously. After the inner ratchet rotates, it drives the rotating drum to rotate, and then the rotating drum drives the gear to rotate, ultimately driving the extrusion assembly to work, thereby reducing dust at the construction site while driving piles.

[0022] Optionally, the base is provided with a plurality of first cylinders, the piston rods of the first cylinders move vertically and movably pass through the base, and a retaining plate is fixedly connected to the piston rods of the first cylinders, the retaining plate abutting against the ground.

[0023] By adopting the above technical solution, and by setting a first cylinder and a retaining plate, when the equipment is moved to a suitable position, the first cylinder can drive the retaining plate to move downward, so that the retaining plate can contact the ground, which greatly increases the friction between the equipment and the ground and improves the stability of piling.

[0024] Optionally, the abutment plate is horizontally arranged, and each abutment plate is provided with a plurality of mounting holes.

[0025] By adopting the above technical solution, bolts can be inserted into the installation hole to fix the abutment plate to the ground, thereby ensuring stability during the piling process and improving the piling effect.

[0026] Optionally, a push rod is fixedly installed on the side of the base away from the pile frame, and several casters are provided on the bottom of the base.

[0027] By adopting the above technical solution, staff can easily move the base on the ground by pushing it with a push rod, and reduce the resistance of the base on the ground by using the moving wheels, thereby improving the convenience of moving the base.

[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. All the equipment used for piling is integrated onto a single base. During piling, the base is moved to the construction position, with the clearance groove positioned above the piling pit. A crane is used to insert the bottom end of the pile into the pit, positioning the pile in the center of the clearance groove and ensuring the bottom ends of the two pile frames are in contact with the ground. The buffer assembly is positioned at the top of the pile. As the lifting plate slides downwards, the swing assembly drives the pile head to swing and strike the buffer assembly. The two pile frames limit the buffer assembly, ensuring the striking block accurately strikes the pile, thus preventing piling deviation and improving accuracy and convenience. Simultaneously, the swing assembly drives the extrusion assembly to work synchronously. Each piling operation causes the extrusion assembly to squeeze water from the water tank, which is then sprayed from the atomizing nozzle, effectively reducing dust and minimizing the health impact of dust on workers.

[0029] 2. The guide plate is slidably connected to the lifting plate, and the two are connected together by a second spring, so that the guide plate slides synchronously with the lifting plate during operation and can move relative to the lifting plate. When the pile head strikes the guide plate, the striking force is applied to the pile through the guide plate, causing the guide plate, the striking block and the pile to descend synchronously to achieve the pile driving effect. After one strike, the guide plate returns to its original position under the elastic force of the second spring.

[0030] 3. The rotating rod and the center rod are connected by a belt drive. When the pile driving rod lifts the pile head upwards, the center rod drives the turntable to rotate synchronously. At this time, the pawl slides over the surface of the inner ratchet, and the inner ratchet is stationary. When the pile driving rod drives the pile head downwards, the pawl inserts into the gap between the two teeth of the inner ratchet, thereby driving the inner ratchet to rotate synchronously. The rotation of the inner ratchet drives the rotating drum to rotate, which in turn drives the gear to rotate, ultimately driving the extrusion assembly to work, thus reducing dust at the construction site while driving piles.

[0044] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.

[0045] This application discloses a small automatic pile driving device.

[0046] Reference Figure 1 A small automatic pile driving device includes a base 11, a pile driving mechanism, a limiting mechanism, and a dust suppression mechanism. The pile driving mechanism, the limiting mechanism, and the dust suppression mechanism are all installed on the base 11, that is, all the devices used for pile driving are integrated on a single base 11. The pile driving mechanism drives the piles to be constructed, and the limiting mechanism limits the piles during the pile driving process to improve the pile driving accuracy. At the same time, the dust suppression mechanism sprays water on the construction site to reduce dust.

[0047] Reference Figure 1 and Figure 2To facilitate moving the base 11 to the desired piling position, several rotatable casters 13 are rotatably mounted on the bottom of the base 11. This embodiment uses four casters as an example. A push rod 12 is fixedly mounted on one side of the base 11 to facilitate moving the device to a suitable position for piling. A clearance groove 17 is provided on the side of the base 11 away from the push rod 12, where the piling to be driven is placed. A horizontal abutment plate 15 is provided on one side of each caster 13. A first cylinder 14 is mounted above each abutment plate 15. The cylinder body of the first cylinder 14 is mounted on the base 11. The piston rod of each first cylinder 14 passes through the base 11 and is fixedly connected to a abutment plate 15. Two mounting holes 16 are provided on each abutment plate 15.

[0048] Reference Figure 2 After the base 11 is positioned correctly, the first cylinder 14 is driven to work, which moves the abutment plate 15 downward, making it contact the ground while the moving wheel 13 does not contact the ground, greatly increasing the friction between the base 11 and the ground. At the same time, bolts are connected inside the mounting hole 16 to fix the abutment plate 15 to the ground, ensuring that the base 11 can be stably fixed to the ground.

[0049] Reference Figure 3 and Figure 4 The piling mechanism includes a lifting plate 26, a drive assembly, a swing assembly, and a pile head 35. The lifting plate 26 is horizontally mounted on the base 11. The drive assembly includes a U-shaped plate 23, guide rods 22, a lead screw 24, and a first motor 25. The U-shaped plate 23 is horizontally mounted above the base 11. Several guide rods 22 are fixedly mounted between the U-shaped plate 23 and the base 11. In this embodiment, four guide rods are used as an example. The guide rods 22 are vertically mounted, and each guide rod 22 slides through the lifting plate 26. A sliding bearing is provided between the lifting plate 26 and each guide rod 22. A side plate 27 is integrally formed on one side of the lifting plate 26. The lead screw 24 passes through the side plate 27 and is threadedly connected to the side plate 27. The first motor 25 is fixedly mounted on the U-shaped plate 23, and the output end of the first motor 25 is coaxially fixedly connected to the lead screw 24. When the first motor 25 is working, it drives the lead screw 24 to rotate. Since the lead screw 24 and the side plate 27 are threaded together, the lead screw 24 drives the lifting plate 26 to rise and fall when it rotates, so as to adjust the height of the lifting plate 26.

[0050] Reference Figure 5 , Figure 6 and Figure 7The swing assembly includes a fixed frame 28, a pile driving rod 33, a rotating shaft 29, and a support rod 30. The fixed frame 28 is fixedly installed on the top of the lifting plate 26. One end of the pile driving rod 33 is fixedly rotated with a rotating rod 32. The rotating rod 32 is horizontally set, and the axis of the rotating rod 32 is perpendicular to the length direction of the pile driving rod 33. Both ends of the rotating rod 32 are rotatably connected to the side wall of the fixed frame 28 through bearings. The other end of the pile driving rod 33 is fixedly connected to the pile driving head 35.

[0051] Reference Figure 6 and Figure 7 The rotating shaft 29 is rotatably installed inside the fixed frame 28. The rotating shaft 29 is parallel to the rotating rod 32. A support rod 30 is fixedly connected to the surface of the rotating shaft 29. The support rod 30 is radially arranged along the rotating shaft 29. A roller 31 is rotatably connected to the end of the support rod 30 away from the rotating shaft 29. An inclined block 34 is fixedly connected to the side of the pile driving rod 33 that is close to the lifting plate 26. When the pile driving rod 33 is in a horizontal state, the inclined block 34 is located between the rotating shaft 29 and the pile driving head 35, and the inclined surface faces the rotating shaft 29.

[0052] Reference Figure 5 and Figure 6 A diagonal rod 40 is fixedly connected to the side of the fixed frame 28 away from the pile head 35. A first connecting seat 41 is fixedly installed at the top of the diagonal rod 40. A second connecting seat 42 is fixedly installed on the side of the pile rod 33 away from the lifting plate 26. A telescopic rod 44 is hinged between the first connecting seat 41 and the second connecting seat 42. A first spring 43 is fixedly connected between the first connecting seat 41 and the second connecting seat 42. The first spring 43 is sleeved on the outside of the telescopic rod 44.

[0053] Reference Figure 5 and Figure 6 A second motor 36 is fixedly connected to the lifting plate 26. The output end of the second motor 36 is coaxially fixedly connected to the first driving wheel 37. The end of the rotating shaft 29 is coaxially fixedly connected to the first driven wheel 38. A first belt 39 is provided between the first driving wheel 37 and the first driven wheel 38.

[0054] Reference Figure 3 , Figure 6 and Figure 7 Before pile driving, the clearance groove 17 is aligned with the pile hole position, and then the pile tip is inserted into the pile hole, so that the pile is placed vertically inside the clearance groove 17. When pile driving is required, the second motor 36 drives the rotating shaft 29 to rotate, and the rotating shaft 29 drives the support rod 30 to rotate synchronously. During the rotation of the support rod 30, the roller 31 lifts the inclined block 34, causing the pile driving rod 33 to rotate around the axis of the rotating rod 32 toward the inclined rod 40. At this time, the pile driving rod 33 drives the pile driving head 35 to lift, and the first spring 43 is compressed. When the roller 31 rotates to the point of disengagement from the inclined block 34, under the elastic force of the first spring 43 and the weight of the pile driving head 35, it can drive the pile driving rod 33 to rotate in the opposite direction, which in turn drives the pile driving head 35 to rotate in the opposite direction to strike the top of the pile, thus realizing pile driving.

[0055] Reference Figure 1 The limiting mechanism includes a pile frame 19, a lifting assembly, and a buffer assembly. A sliding groove 18 is provided on each of the two opposite side walls of the clearance groove 17. One pile frame 19 is slidably disposed inside each sliding groove 18. The pile frames 19 are U-shaped, with their openings facing each other. A lifting assembly is provided on each side of the two pile frames 19 that are far apart from each other. Each lifting assembly includes a second cylinder 20 and a top plate 21. The top plate 21 is horizontally disposed and fixedly installed on the top of the pile frame 19. The second cylinder 20 is located below the top plate 21 and fixedly installed on the base 11. The piston rod of the second cylinder 20 moves vertically and is fixedly connected to the bottom of the top plate 21. The second cylinder 20 drives the pile frame 19 to rise and fall, allowing the bottom of the pile frame 19 to contact the ground, ensuring the normal operation of the piling work. This eliminates the need for continuous manual installation and disassembly of the pile frame 19, saving time spent on installation and disassembly.

[0056] Reference Figure 1 , Figure 5 and Figure 8 The buffer assembly includes a guide plate 66, a striking block 71, a limiting seat 68, and a sliding rod 69. The guide plate 66 is horizontally positioned and slidably disposed between two pile frames 19. The striking block 71 is fixedly disposed at the bottom center of the guide plate 66. Two limiting seats 68 are fixedly disposed along the length of the guide plate 66 on the side of the lifting plate 26 near the guide plate 66. The limiting seats 68 are L-shaped. A sliding rod 69 is slidably passed through each limiting seat 68, and a fixing plate 67 is fixedly fixed to the top of each sliding rod 69. The fixing plate 67 is fixedly connected to one side of the guide plate 66. A second spring 70 is fixedly connected between each fixing plate 67 and each limiting seat 68, and the second spring 70 is sleeved on the outside of the sliding rod 69.

[0057] Reference Figure 5 and Figure 8 During operation, the guide plate 66 is positioned above the top of the pile, and the bottom end of the striking block 71 contacts the top of the pile. At this time, the second spring 70 is in a compressible state, reserving one driving stroke for each pile driving. Then, the first pile driving is carried out. During this process, the pile head 35 strikes the guide plate 66, and the striking force can be applied to the pile through the guide plate 66 and the striking block 71, realizing the synchronous descent of the guide plate 66, the striking block 71, and the pile.

[0058] Reference Figure 9 and Figure 10The dust suppression mechanism includes a water tank 59, a water pipe 60, an atomizing nozzle 61, an extrusion assembly, and a one-way transmission assembly. The water tank 59 is fixedly mounted on the lifting plate 26, located on one side of the fixed frame 28. The water tank 59 is cylindrical and its axis is horizontal. The atomizing nozzle 61 is fixedly mounted on the lifting plate 26, located on the side of the lifting plate 26 near the clearance groove 17. The water pipe 60 connects the atomizing nozzle 61 and the water tank 59. To ensure the stability of the water pipe 60, two pipe fixing parts 62 are fitted onto the water pipe 60, and each pipe fixing part 62 is fixedly connected to the lifting plate 26.

[0059] Reference Figure 10 and Figure 11 The extrusion assembly includes a piston 63, a moving rod 64, a rack 57, and a gear 56. The piston 63 is circular and coaxially mounted inside the water tank 59. The moving rod 64 is aligned with the axis of the piston 63 along its length and slides through the end of the water tank 59 away from the atomizing nozzle 61. One end of the moving rod 64 is fixedly connected to the piston 63. A guide rail 65 is fixedly mounted on the lifting plate 26, and the other end of the moving rod 64 is slidably connected to the guide rail 65. The rack 57 is fixedly mounted at the bottom of the moving rod 64, and the gear 56 is located below the rack 57 and meshes with it. When the gear 56 rotates, it drives the rack 57 to move, causing the piston 63 to extrude water from the water tank 59 and spray it out from the atomizing nozzle 61.

[0060] Reference Figure 9 , Figure 11 and Figure 12 The one-way transmission assembly includes a central rod 48, a rotating drum 55, an inner ratchet 52, a turntable 50, a pawl 51, and a spring 54. Two mounting plates 49 are fixed on the lifting plate 26. The mounting plates 49 are located at the end of the water tank 59 away from the water pipe 60. The central rod 48 is rotatably connected between the two mounting plates 49. The central rod 48 and the rotating rod 32 are arranged in parallel. One end of the rotating rod 32 is coaxially fixedly connected to the second driving wheel 45, and one end of the central rod 48 is coaxially fixedly connected to the second driven wheel 46. A second belt 47 is provided between the second driven wheel 46 and the second driving wheel 45. When the rotating rod 32 rotates, it drives the central rod 48 to rotate synchronously.

[0061] Reference Figure 9 , Figure 11 and Figure 12A rotating drum 55 is coaxially sleeved outside the central rod 48. A fixed seat 58 is fixedly installed on the lifting plate 26. The rotating drum 55 rotatably passes through the fixed seat 58. A gear 56 is fixedly sleeved outside the rotating drum 55. An inner ratchet 52 is fixedly sleeved outside the rotating drum 55.

One end of a pawl 51 is rotatably mounted on the turntable 50, and the other end of the pawl 51 is engaged with the inner ratchet 52. A limit plate 53 is fixedly installed on the turntable 50. One end of a spring piece 54 is fixedly connected to the limit plate 53, and the other end of the spring piece 54 abuts against the surface of the pawl 51.

[0062] Reference Figure 9 , Figure 11 and Figure 12 When driving piles, the pile driving rod 33 rotates downward to achieve the pile driving action, that is, the rotating rod 32 rotates in the direction closer to the pile driving head 35. The rotating rod 32 drives the central rod 48 and the turntable 50 to rotate in the same direction. The pawl 51 rotates with the turntable 50. Since the pawl 51 is engaged with the inner ratchet 52, the inner ratchet 52 rotates synchronously with the turntable 50, and then drives the gear 56 to rotate through the rotating cylinder 55, thereby driving the extrusion component to work. When the pile driving rod 33 rotates upward, the pawl 51 will not drive the inner ratchet 52 to rotate, that is, it cannot drive the extrusion component to work. Thus, dust suppression can be achieved once every time the pile driving head 35 rotates downward to drive piles, thereby achieving the effect of dust suppression while driving piles.

[0063] The implementation principle of a small automatic pile driving device according to an embodiment of this application is as follows: The base 11 is moved using a push rod 12 and a moving wheel 13, allowing the device to move to a suitable position while ensuring the pile is located in the center of the clearance groove 17. Two pile frames 19 are located on either side of the pile. The first cylinder 14 is driven to work, causing the clamping plate 15 to move downwards, making it contact the ground and fixing it in place. Then, the second cylinder 20 is controlled to raise and lower the pile frame 19, making its bottom contact the ground. The first motor 25 is then controlled to rotate the lead screw 24, causing the lifting plate 26 to descend while the guide plate 66 and the striking block 71 descend, until the bottom of the striking block 71 contacts the top of the pile.

[0064] Then, the second motor 36 drives the rotating shaft 29 and the support rod 30 to rotate. During the rotation of the support rod 30, the roller 31 lifts the inclined block 34, causing the pile driving rod 33 to drive the pile driving head 35 to rotate and lift. At this time, the first spring 43 is compressed. When the roller 31 rotates to the point of disengaging from the inclined block 34, it rotates in the opposite direction under the elastic force of the first spring 43 and the gravity of the pile driving head 35, causing the pile driving head 35 to strike the guide plate 66. The striking force is applied to the pile through the guide plate 66. After the pile sinks, the drive assembly drives the lifting plate 26 to move downward again, which facilitates another pile driving operation.

[0065] During pile driving, when the pile is driven, the rotating rod 32 drives the central rod 48 to rotate in the same direction. At this time, the pawl 51 rotates with the turntable 50 and engages with the inner ratchet 52. The inner ratchet 52 rotates synchronously with the turntable 50 and drives the gear 56 to rotate through the rotating cylinder 55. When the gear 56 rotates, it drives the rack 57 to move closer to the water tank 59. The piston 63 can squeeze the water inside the water tank 59 into the water pipe 60 and spray it out through the atomizing nozzle 61 to achieve the effect of dust suppression. That is, when not driving piles, the rotating rod 32 rotates in the opposite direction, and the turntable 50 drives the pawl 51 to rotate. At this time, the pawl 51 slides over the back of the teeth of the inner ratchet 52, and the inner ratchet 52 is in a stationary state, that is, it cannot drive the pressing component to work. Thus, every time the pile head 35 rotates downward to drive the pile, water is sprayed once at the atomizing nozzle 61 to achieve dust suppression once, thereby achieving the effect of dust suppression while driving piles.

[0066] 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.
