Description

Technical Field

[0001] This invention relates to the field of pile driver technology, and in particular to a pile driver for building construction. Background Technology

[0002] Piling machines are often used in the construction of foundation pits in water conservancy projects. Piling machines are used to drive piles into the ground to serve as the foundation for supporting structures. By driving piles into the soil quickly and evenly, piling machines can provide strong support and stability, ensuring the structural integrity and reliability of buildings.

[0003] In existing construction projects, pile drivers are operated from a control room. The tracked wheels move the machine, which in turn moves the frame and hammer. When the machine reaches the designated position, an external crane moves the pile to a position below the hammer and vertically to the ground. At this point, a winch is activated, releasing a steel cable that causes the hammer to fall and collide with the top of the pile. Simultaneously, the winch retracts the steel cable, returning the hammer to its highest position. This process is repeated to strike the pile, driving it into the soil and completing the pile driving operation inside the foundation pit.

[0004] However, due to the large impact force experienced by the piles when they are driven into the ground, the piles may tilt or shift during the driving process, causing the piles to be driven out of the designated location and area, thus affecting the piles' support effect on the building. Summary of the Invention

[0005] This invention addresses the problem that the large impact force experienced by piles when driven into the ground can cause them to tilt or deviate during the driving process, resulting in the piles not reaching the designated position and area, thus affecting their support effect on the building. The invention provides a pile driver for construction engineering.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pile driver for construction engineering, comprising a machine body, a track wheel provided on one side of the machine body, a control room provided on one side of the machine body, a support pole provided on one side of the machine body, a winch provided on one side of the machine body, a steel rope provided on one side of the support pole, one end of the steel rope being connected to the output end of the winch, and a striking block provided at the other end of the steel rope, and a positioning device for straightening and assisting in limiting the pile column provided on one side of the support pole.

[0007] The aforementioned components achieve the following effects: First, personnel operate the track wheels from the control room, causing the track wheels to move the machine body, which in turn moves the frame and hammer block. When the machine body reaches the designated position, an external crane moves the pile to a position below the hammer block and vertically to the ground. At this point, the winch is activated, releasing the steel cable, causing the hammer block to fall and collide with the top of the pile. Simultaneously, the winch retracts the steel cable, returning the hammer block to its highest position. This process is repeated to strike the pile, causing it to penetrate the soil under the continuous impact of the hammer block, thus completing the piling operation inside the foundation pit.

[0008] Preferably, the positioning device includes a frame, an adjustment device between the frame and the support rod, the frame being sleeved on the surface of the support rod, two first circular holes symmetrically formed on the surface of the frame, two positioning holes symmetrically formed on the surface of the frame, retaining rings fixedly connected to the side of the frame near each of the two first circular holes, a circular hole frame fixedly connected to one side of the frame, a drive motor fixedly connected to one side of the circular hole frame, a circular shaft fixedly connected to the output end of the drive motor, the circular shaft being located inside the frame, two first gears symmetrically fixedly connected to the surface of the circular shaft, one of the first gears being located inside the circular hole frame, a screw being provided inside each of the two first circular holes, and two retaining rings... Each screw is fitted onto the surface of two screws. One end of each screw is fixedly connected to a positioning rod, which is slidably connected to the inner wall of two positioning holes. A rectangular cover is fixedly connected to the adjacent end of each screw. Multiple rollers are rotatably connected to the inner wall of each rectangular cover. The other end of each positioning rod is fixedly connected to the two rectangular covers. A threaded toothed ring is threaded onto the surface of each screw. A slot is provided on one side of each threaded toothed ring, which is fitted onto the surface of two retaining rings through the slot. A toothed chain is fitted onto the surface of each of the two first gears and the two threaded toothed rings. The two toothed chains mesh with the two corresponding first gears and threaded toothed rings.

[0009] The effect achieved by the above components is as follows: By setting the positioning device, the pile is first placed inside the frame, so that the pile is positioned between the two rectangular covers. At this time, the drive motor is started, causing the drive motor to drive the round shaft to rotate, which in turn drives the two first gears to rotate. The two first gears, through the gear chain, drive the two screw rings to rotate, causing the two screw rings to rotate along the surface of the retaining ring. This causes the two screw rings to drive the two screws to move in opposite directions, which in turn drives the two positioning rods to move in opposite directions along the inside of the two positioning holes. This causes the two screws to drive the two rectangular covers to move in opposite directions, so that the two rectangular covers move in opposite directions. The rectangular covers drive multiple rollers to move in opposite directions. When two rectangular covers move to the position where the rollers press against the pile surface, the two rectangular covers, together with the multiple rollers, clamp and fix the pile. When the pile is struck, the rotation of the rollers allows the pile to continue moving downwards while being clamped, thus achieving the clamping and positioning of the pile. This reduces the likelihood of the pile tilting or shifting due to impact force during the driving process, preventing the pile from being driven out of the designated position and area, which would affect the pile's support effect on the building. This improves the stability of pile driving and the quality of construction.

[0010] Preferably, a rectangular plate is fixedly connected to the inner wall of the frame, a first electric telescopic rod is fixedly connected to one side of the rectangular plate, a first roller frame is fixedly connected to the output end of the first electric telescopic rod, a second circular hole is opened on one side of the rectangular plate, a third circular hole is opened on one side of the frame, a circular groove is opened on one side of the frame, a spring rod is slidably connected to the inner wall of the circular groove, the other end of the spring rod is fixedly connected to the frame, a second roller frame is fixedly connected to the end of the spring rod away from the frame, a rope is fixedly connected to the side of the second roller frame close to the frame, the rope is located inside the second circular hole and the third circular hole, a reel is fixedly connected to the end of the rope away from the second roller frame, and the reel is fixedly sleeved on the surface of the circular shaft.

[0011] The effects achieved by the aforementioned components are as follows: By setting up the first and second roller frames, after personnel place the pile into the frame using an external crane, the drive motor is activated, causing the drive motor to rotate the circular shaft, which in turn rotates the reel. The reel winds up the rope, causing the rope to move along the inside of the second and third circular holes. This causes the rope to pull the second roller frame closer to the frame, which in turn pushes the pile closer to the first roller frame. Simultaneously, the first electric telescopic rod is activated, moving the first roller frame closer to the second roller frame. When the first roller frame reaches the position where it is in contact with the pile, the pile is pushed to the designated position by the second roller frame and then intercepted by the first roller frame. This straightens the pile and quickly places it into the clamping area of ​​the two rectangular covers. In conjunction with the rectangular covers on both sides, the pile is straightened and quickly positioned, allowing it to be quickly corrected and positioned after being placed inside the frame. This improves the construction efficiency and ease of pile driving.

[0012] Preferably, a reinforcing block is fixedly connected to one end of the rope near the second roller frame, and the reinforcing block is fixedly connected to the second roller frame.

[0013] The effect achieved by the above components is that by setting up the reinforcing blocks, the connection strength between the rope and the second roller frame can be increased, reducing the possibility of the rope separating when the second roller frame is pulled.

[0014] Preferably, a plurality of auxiliary strips are symmetrically fixedly connected to the surface of the opening of the frame, and the plurality of auxiliary strips are arranged at equal intervals.

[0015] The effect achieved by the above components is that by setting auxiliary strips, the auxiliary strips can intercept the piles, reduce the contact area between the piles and the frame entrance, and reduce the large wear on the surface of the piles when they are pushed in by the second roller frame.

[0016] Preferably, the frame has two L-plates fixedly connected symmetrically to its surface, and the two toothed chains are respectively disposed inside the two L-plates.

[0017] The effect achieved by the above components is that by setting the L-plate, the L-plate can intercept and limit the toothed chain, reducing the positional deviation of the toothed chain during use and affecting the normal transmission of the screw hole toothed ring.

[0018] Preferably, the inner walls of the two rectangular covers are symmetrically and fixedly connected to two second electric telescopic rods, the output ends of the four second electric telescopic rods are fixedly connected to round rods, multiple steel wire ropes are fixedly connected between two corresponding round rods, and multiple intercepting blocks are fixedly connected to the surface of the multiple steel wire ropes.

[0019] The aforementioned components achieve the following effect: By setting up intercepting blocks, when personnel need to position smaller piles, the smaller piles are first clamped using two rectangular covers and multiple rollers. Then, the two corresponding second electric telescopic rods inside the rectangular covers are activated, causing the four second electric telescopic rods to push their corresponding two round rods to move in opposite directions. These round rods then push multiple steel wire ropes and multiple intercepting blocks to move in opposite directions. When the multiple intercepting blocks, in conjunction with the steel wire ropes, move to a position where they are in contact with the pile surface, they cover the pile surface and provide auxiliary restraint. This reduces the possibility that the first and second roller frames cannot contact the smaller pile surface when positioning it, preventing the smaller pile from tilting away from the rectangular covers. This further improves the flexibility of pile positioning.

[0020] Preferably, each of the multiple intercepting blocks has multiple balls on one side, and the multiple balls are arranged at equal intervals.

[0021] The effect achieved by the above components is that by setting ball bearings, the ball bearings can reduce the friction and wear between the intercepting block and the pile surface by utilizing their own rotational properties, thereby increasing the service life of the intercepting block.

[0022] Preferably, the adjusting device includes a guide rail, which is fixedly connected to the frame rod and located inside the frame. The circular shaft is located inside the guide rail. A T-shaped frame is fixedly connected to the side of the guide rail away from the frame rod. A toothed rod is fixedly connected to the inner wall of the T-shaped frame. A T-shaped groove is formed on one side of the frame. A rectangular hole is formed on the side of the frame near the T-shaped groove. The inner wall of the rectangular hole is connected to the inner wall of the T-shaped groove. The surface of the T-shaped frame is slidably connected to the inner wall of the T-shaped groove. A circular hole block is fixedly connected to the side of the frame near the rectangular hole. A self-locking motor is fixedly connected to one side of the circular hole block. A second gear is fixedly connected to the output end of the self-locking motor. The second gear is located inside the rectangular hole, and the surface of the second gear meshes with the surface of the toothed rod.

[0023] The effect achieved by the above components is as follows: By setting the adjustment device, the self-locking motor is first started, which drives the second gear to rotate. Under the action of the second gear meshing with the rack, the second gear moves up and down along the surface of the rack during rotation. The output shaft of the self-locking motor drives the round hole block to move, which in turn drives the frame to slide up and down along the T-shaped frame surface under the action of the T-slot. This causes the frame to move the two rectangular covers up and down. When the two rectangular covers move to a position lower than the top of the pile, the height of the frame is adjusted, so that the two rectangular covers can always be positioned at the middle of the pile or below the top of the pile for positioning. This reduces the situation where the height of the rectangular covers is higher than the top of the pile during the process of the pile being driven into the ground, which affects the normal impact of the striking block on the pile, and improves the pile driving efficiency of the striking block.

[0024] Preferably, a support plate is fixedly connected to one side of the guide rail, and the support plate is fixedly connected to the frame rod.

[0025] The effect achieved by the above components is that by setting up a support plate, the support plate can increase the connection strength between the guide rail and the frame rod, and reduce the possibility of the guide rail separating from the frame rod under stress during use.

[0026] In summary, the beneficial effects of the present invention are as follows: By setting up a positioning device, the pile can be limited during the process of being driven into the ground, reducing the possibility of the pile tilting or shifting due to impact force during the driving process. This would prevent the pile from being driven out of the designated position and area, thus affecting the pile's support effect on the building and improving the stability of pile driving and construction quality.

[0027] By setting an adjustment device, the positioning device can always be positioned at the middle of the pile or below the top of the pile, which reduces the situation where the height of the rectangular cover is higher than the top of the pile during the process of the pile being driven into the ground, thus affecting the normal impact of the striking block on the pile and improving the pile driving efficiency of the striking block.

[0030] Reference Figure 1-10As shown, this embodiment discloses a pile driver for construction engineering, including a body 1, a track wheel 2 on one side of the body 1, a control room 3 on one side of the body 1, a support pole 4 on one side of the body 1, a winch 5 on one side of the body 1, a steel cable 6 on one side of the support pole 4, one end of the steel cable 6 being connected to the output end of the winch 5, and the other end of the steel cable 6 being equipped with a striking block 7. A positioning device 8 for straightening and assisting in limiting the pile column is provided on one side of the support pole 4. First, the personnel operate the track wheel 2 from inside the control room 3, causing the track wheel 2 to rotate. The machine body 1 is moved, which in turn moves the frame rod 4 and the hammer block. When the machine body 1 moves to the designated position, the pile is moved by an external crane to a position below the hammer block 7 and vertically placed on the ground. At this time, the winch 5 is started, which releases the steel cable 6, causing the hammer block 7 to fall and collide with the top of the pile. At the same time, the winch 5 retracts the steel cable 6, returning the hammer block 7 to its highest position. This operation is repeated to strike the pile, causing the pile to enter the soil under the continuous impact of the hammer block 7, thus completing the pile driving operation inside the foundation pit.

[0031] Reference Figure 3-10As shown, this embodiment discloses a positioning device 8 including a frame 81. An adjustment device 9 is provided between the frame 81 and the support rod 4. The frame 81 is sleeved on the surface of the support rod 4. Two first circular holes 83 are symmetrically opened on the surface of the frame 81, and two positioning holes 84 are symmetrically opened on the surface of the frame 81. A retaining ring 85 is fixedly connected to one side of the frame 81 near the two first circular holes 83. A circular hole frame 82 is fixedly connected to one side of the frame 81. A drive motor 814 is fixedly connected to one side of the circular hole frame 82. A circular shaft 815 is fixedly connected to the output end of the drive motor 814. The circular shaft 815 is located inside the frame 81. Two first gears 816 are symmetrically fixedly connected to the surface of the circular shaft 815, one of which is located inside the circular hole frame 82. The first circular hole 83 is equipped with a screw 817 inside. Two retaining rings 85 are respectively fitted onto the surfaces of the two screws 817. One end of each screw 817 is fixedly connected to a positioning rod 820. The two positioning rods 820 are slidably connected to the inner walls of the two positioning holes 84. A rectangular cover 821 is fixedly connected to the adjacent ends of each screw 817. Multiple rollers 822 are rotatably connected to the inner walls of each rectangular cover 821. The other ends of the two positioning rods 820 are fixedly connected to the two rectangular covers 821. A threaded toothed ring 818 is threaded onto the surface of each screw 817. A retaining groove 823 is opened on one side of each of the two toothed rings 818. The two toothed rings 818 are respectively fitted onto the surfaces of the two retaining rings 85 through the retaining grooves 823. The two first gears A toothed chain 819 is fitted onto the surface of both the first gear 816 and the two threaded gear rings 818. The two toothed chains 819 mesh with the two corresponding first gears 816 and threaded gear rings 818, respectively. By setting the positioning device 8, the pile is first placed inside the frame 81, so that the pile is located between the two rectangular covers 821. At this time, the drive motor 814 is started, so that the drive motor 814 drives the round shaft 815 to rotate, so that the round shaft 815 drives the two first gears 816 to rotate, so that the two first gears 816 drive the two threaded gear rings 818 to rotate through the toothed chains 819, so that the two threaded gear rings 818 rotate along the surface of the retaining ring 85, so that the two threaded gear rings 818 drive the two screws 817 to move in opposite directions, so that the two screws 817 drive the two positioning rods. The screws 817 move in opposite directions along the two positioning holes 84, causing the two rectangular covers 821 to move in opposite directions. These rectangular covers 821 then drive multiple rollers 822 to move in opposite directions. When the two rectangular covers 821 move to the position where the rollers 822 press against the pile surface, they work with the rollers 822 to clamp and fix the pile. When the pile is struck, the rotation of the rollers 822 allows it to continue moving downwards while being clamped, thus achieving proper clamping and positioning. This reduces the risk of the pile tilting or shifting due to impact during driving into the ground, preventing the pile from being driven into the designated position and area, and thus affecting the pile's support effect on the building.This improved the stability of pile driving and the quality of construction.

[0032] Reference Figure 4-7 As shown, this embodiment discloses a rectangular plate 86 fixedly connected to the inner wall of the frame 81. A first electric telescopic rod 87 is fixedly connected to one side of the rectangular plate 86. A first roller frame 88 is fixedly connected to the output end of the first electric telescopic rod 87. A second circular hole 89 is opened on one side of the rectangular plate 86, a third circular hole 810 is opened on one side of the frame 81, and a circular groove 813 is opened on one side of the frame 81. A spring rod 832 is slidably connected to the inner wall of the circular groove 813. The other end of the spring in the spring rod 832 is fixedly connected to the frame 81, and a second roller frame 83 is fixedly connected to the end of the spring rod 832 away from the frame 81. 1. A rope 830 is fixedly connected to the side of the second roller frame 831 near the frame 81. The rope 830 is located inside the second circular hole 89 and the third circular hole 810. A reel 829 is fixedly connected to the end of the rope 830 away from the second roller frame 831. The reel 829 is fixedly sleeved on the surface of the circular shaft 815. By setting up the first roller frame 88 and the second roller frame 831, when personnel use an external crane to put the pile into the frame 81, the drive motor 814 is started, causing the drive motor 814 to drive the circular shaft 815 to rotate, which in turn drives the reel 829 to rotate, so that the reel 829 rotates the rope. 830 is wound up, causing the rope 830 to move inside the second circular hole 89 and the third circular hole 810. This pulls the second roller frame 831 towards the frame 81, causing the second roller frame 831 to push the pile towards the first roller frame 88. Simultaneously, the first electric telescopic rod 87 is activated, moving the first roller frame 88 towards the second roller frame 831. When the first roller frame 88 reaches the position where it contacts the pile, the pile is pushed to the designated position by the second roller frame 831 and then intercepted by the first roller frame 88, thus straightening the pile and quickly reaching both... The clamping area of ​​the rectangular cover 821, together with the rectangular covers 821 on both sides, achieves the straightening and rapid positioning of the pile column, so that the pile column can be quickly corrected and positioned after being placed inside the frame 81, which improves the construction efficiency of personnel and the convenience of pile driving. The end of the rope 830 near the second roller frame 831 is fixedly connected to the reinforcing block 833. The reinforcing block 833 is fixedly connected to the second roller frame 831. By setting the reinforcing block 833, the connection strength between the rope 830 and the second roller frame 831 can be increased, reducing the possibility of the rope 830 separating when pulling the second roller frame 831.

[0033] Reference Figure 5As shown, this embodiment discloses that multiple auxiliary strips 812 are symmetrically fixedly connected to the surface of the opening of the frame 81. The multiple auxiliary strips 812 are arranged at equal intervals. By setting the auxiliary strips 812, the auxiliary strips 812 can intercept the pile, reduce the contact area between the pile and the entrance of the frame 81, and reduce the large wear on the surface of the pile when it is pushed in by the second roller frame 831. Two L plates 811 are symmetrically fixedly connected to the surface of the frame 81, and two toothed chains 819 are respectively set inside the two L plates 811. By setting the L plates 811, the L plates 811 can intercept and limit the toothed chains 819, reduce the positional deviation of the toothed chains 819 during use, and affect the normal transmission of the screw hole toothed ring 818.

[0034] Reference Figure 10 As shown, this embodiment discloses two second electric telescopic rods 824 symmetrically fixedly connected to the inner walls of two rectangular covers 821. Round rods 825 are fixedly connected to the output ends of all four second electric telescopic rods 824. Multiple steel wire ropes 826 are fixedly connected between two corresponding round rods 825. Multiple intercepting blocks 827 are fixedly connected to the surfaces of the steel wire ropes 826. By setting the intercepting blocks 827, when personnel need to position a small pile, the two rectangular covers 821 and multiple rollers 822 are used to clamp the small-volume pile. At this time, the two corresponding second electric telescopic rods 824 inside the rectangular covers 821 are activated, causing the four second electric telescopic rods 824 to push the corresponding two round rods 825 to move in opposite directions, so that the two round rods 825 on both sides push the multiple steel wire ropes 826 respectively. The multiple intercepting blocks 827 move in opposite directions. When the multiple intercepting blocks 827, together with the steel wire rope 826, move to a position that is in contact with the surface of the pile, the multiple intercepting blocks 827, together with the multiple steel wire rope 826, cover the surface of the pile and provide auxiliary restraint. This reduces the situation where the first roller frame 88 and the second roller frame 831 cannot be in contact with the surface of the small-volume pile when the two rectangular covers 821 are positioning the pile. This prevents the small-volume pile from tilting away from the two rectangular covers 821, and further improves the positioning flexibility of the pile. Each of the multiple intercepting blocks 827 is provided with multiple balls 828 on one side. The multiple balls 828 are arranged at equal intervals. By setting the balls 828, the balls 828 can use their own rotational properties to reduce the friction and wear between the intercepting blocks 827 and the surface of the pile, thereby improving the service life of the intercepting blocks 827.

[0035] Reference Figure 3 and Figure 4 as well as Figure 5As shown, this embodiment discloses an adjustment device 9 including a guide rail 91, which is fixedly connected to the support rod 4. The guide rail 91 is located inside the frame 81, and a round shaft 815 is located inside the guide rail 91. A T-shaped frame 92 is fixedly connected to the side of the guide rail 91 away from the support rod 4. A gear 93 is fixedly connected to the inner wall of the T-shaped frame 92. A T-shaped groove 98 is opened on one side of the frame 81, and a rectangular hole 99 is opened on the side of the frame 81 near the T-shaped groove 98. The inner wall of the rectangular hole 99 is connected to the inner wall of the T-shaped groove 98. The surface of the T-shaped frame 92 is slidably connected to the inner wall of the T-shaped groove 98. A round hole block 94 is fixedly connected to the side of the frame 81 near the rectangular hole 99, and a self-locking motor 95 is fixedly connected to the side of the round hole block 94. A second gear 96 is fixedly connected to the output end of the self-locking motor 95. The second gear 96 is located inside the rectangular hole 99, and the surface of the second gear 96 meshes with the surface of the gear 93. By setting the adjustment device 9... First, the self-locking motor 95 is started, which drives the second gear 96 to rotate. Under the action of the second gear 96 meshing with the rack 93, the second gear 96 moves up and down along the surface of the rack 93 during rotation. The output shaft of the self-locking motor 95 drives the circular hole block 94 to move, which in turn drives the frame 81 to slide up and down along the surface of the T-shaped frame 92 under the action of the T-slot 98. This causes the frame 81 to drive the two rectangular covers 821 to move up and down. When the two rectangular covers 821 move to a position lower than the top of the pile, the height of the frame 81 is adjusted, so that the two rectangular covers 821 can always be positioned in the middle of the pile or below the top of the pile for positioning. This reduces the situation where the height of the rectangular covers 821 is higher than the top of the pile during the process of the pile being driven into the ground, which affects the normal impact of the striking block 7 on the pile, and improves the pile driving efficiency of the striking block 7.

[0036] Reference Figure 3 and Figure 4 as well as Figure 5 As shown, this embodiment discloses that a support plate 97 is fixedly connected to one side of the guide rail 91. The support plate 97 is fixedly connected to the frame rod 4. By setting the support plate 97, the support plate 97 can increase the connection strength between the guide rail 91 and the frame rod 4, and reduce the situation where the guide rail 91 separates from the frame rod 4 under stress during use.

[0037] The working principle is as follows: First, the personnel operate the track wheels 2 in the control room 3, which drives the machine body 1 to move. The machine body 1 then drives the frame rod 4 and the hammer block to move. When the machine body 1 moves to the designated position, the pile is moved to a position below the hammer block 7 and vertically placed on the ground by an external crane. At this time, the winch 5 is started, which releases the steel cable 6, causing the hammer block 7 to fall and collide with the top of the pile. At the same time, the winch 5 retracts the steel cable 6, returning the hammer block 7 to its highest position. This operation is repeated to strike the pile, causing the pile to penetrate into the soil under the continuous impact of the hammer block 7, thus completing the pile driving operation inside the foundation pit.

[0038] First, the pile is placed inside the frame 81, positioned between the two rectangular covers 821. Then, the drive motor 814 is activated, causing the circular shaft 815 to rotate. This, in turn, drives two first gears 816, which in turn drive two threaded gear rings 818 via gear chains 819. These rings rotate along the surface of the retaining ring 85, causing two screws 817 to move in opposite directions. These screws then drive two positioning rods 820 to move in opposite directions along the interior of two positioning holes 84. This, in turn, causes the two rectangular covers 821 to move in opposite directions, which in turn drive multiple rollers 822 to move in opposite directions. When the two rectangular covers 821 move to the position where the rollers 822 press against the pile surface, they clamp and fix the pile in place. When the pile is struck, the rotation of the rollers 822... Under the action, the pile can continue to move downwards while being clamped. At the same time, the drive motor 814 is activated, which drives the circular shaft 815 to rotate. The circular shaft 815 drives the reel 829 to rotate, causing the reel 829 to wind up the rope 830. The rope 830 moves along the inside of the second circular hole 89 and the third circular hole 810, causing the rope 830 to pull the second roller frame 831 to move closer to the frame 81. The second roller frame 831 pushes the pile closer to the first roller frame 88. At the same time, the first electric telescopic rod 87 is activated, which drives the first roller frame 88 to move closer to the second roller frame 831. When the first roller frame 88 moves to the position where it is in contact with the pile, the pile is pushed to the designated position by the second roller frame 831 and then intercepted by the first roller frame 88. This straightens the pile and quickly reaches the clamping area of ​​the two rectangular covers 821. With the cooperation of the rectangular covers 821 on both sides, the pile is straightened and quickly positioned.

[0039] When personnel need to position smaller piles, the small-volume piles are first clamped using two rectangular covers 821 and multiple rollers 822. Then, the two corresponding second electric telescopic rods 824 inside the rectangular covers 821 are activated, causing the four second electric telescopic rods 824 to push the corresponding two round rods 825 to move in opposite directions. This causes the two round rods 825 on both sides to push multiple steel wire ropes 826 and multiple intercepting blocks 827 to move in opposite directions. When the multiple intercepting blocks 827 move in conjunction with the steel wire ropes 826 to a position that is in contact with the surface of the pile, the multiple intercepting blocks 827 and the multiple steel wire ropes 826 cover the surface of the pile and provide auxiliary restraint, thereby achieving further positioning of the small-volume pile.

[0040] When the pile is struck to a position where its top is close to the surface of the rectangular cover 821, the self-locking motor 95 is activated, causing the self-locking motor 95 to drive the second gear 96 to rotate. Under the action of the second gear 96 meshing with the rack 93, the second gear 96 moves up and down along the surface of the rack 93 during rotation. The output shaft of the second gear 96, in conjunction with the self-locking motor 95, drives the circular hole block 94 to move, causing the circular hole block 94 to drive the frame 81 to slide up and down along the surface of the T-shaped frame 92 under the action of the T-slot 98. This causes the frame 81 to drive the two rectangular covers 821 to move up and down. When the two rectangular covers 821 move to a position lower than the top of the pile, the height of the frame 81 is adjusted.
