Description

Technical Field

[0001] The present invention relates to the technical field of power grid engineering equipment, and in particular to an intelligent pole grabber. Background Art

[0002] During the installation of power facilities, the placement of poles is a critical step. Traditional pole placement methods rely heavily on manual labor combined with simple machinery, resulting in low efficiency and potential safety hazards. For example, when placing a pole after drilling a hole in the ground, it is difficult to ensure that the pole is placed smoothly and intact in the hole, and problems such as tilting and scratching are prone to occur. Moreover, during the lowering of the pole, there is a lack of effective clamping and guiding structures, and the clamping force cannot be automatically adjusted according to changes in the pole diameter, resulting in poor stability of the pole. In addition, the drilling equipment and pole clamping equipment are mostly independent structures, which are cumbersome to operate and have poor coordination. At the same time, the lack of effective protection for the drill bit during the drilling process increases the risk of injury to workers.

[0003] Therefore, a device is needed that can complete the pole placement operation efficiently, safely and stably. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the existing installation of electric poles, such as it is difficult to maintain the vertical state, it is difficult to control the accuracy of the pole lowering, and the electric pole is damaged due to tilting and scratching. An intelligent pole grabber is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An intelligent pole grabber comprises a crane, wherein a drilling rig and a drill barrel are provided above the crane;

[0007] The end of the mechanical arm at the top of the crane is rotatably connected to a drilling rig, which includes a drill barrel, a drill bit, and a rotating shaft. The drilling rig is used to drill holes in the ground to facilitate the subsequent placement of electric poles.

[0008] The drill barrel is fixed on one side of the drilling rig. The drill barrel includes a connecting frame, a slewing support and a bracket plate. Two sets of clamping structures are provided in the bracket plate for clamping the electric pole, and the two sets of clamping structures are arranged up and down;

[0009] A lowering structure is provided in the support plate, and the lowering structure is located between two groups of clamping structures.

[0010] In one possible design, the drilling rig also includes a lifting plate sliding in the drill barrel, the rotating shaft rotates at the bottom of the lifting plate, the drill bit is fixed at the bottom end of the rotating shaft, the rotating shaft and the drill bit cooperate to drill holes in the ground, a threaded rod is connected to the drill barrel through the base rotation, and the threaded rod is threadedly connected to the lifting plate to drive the drill bit to rise and fall; the threaded rod is driven to rotate by the motor, and the threaded rod drives the drill bit and the lifting plate to rise and fall, and the motor drives the drill bit to rotate through the rotating shaft, and then cooperates with the lifting of the lifting plate to perform drilling operations, which is convenient for the later placement of electric poles.

[0011] In one possible design, the clamping structure includes a first claw and a second claw that are rotated in the bracket plate through a pin shaft, and a claw cylinder is rotatably connected in the bracket plate. The output shaft of the claw cylinder is rotatably connected to one end of the first claw, and the ends of the first claw and the second claw that are close to each other are rotatably connected through a connecting rod, which is used to drive the second claw to rotate synchronously through the connecting rod when the first claw rotates to complete the clamping of the pole. A constraint structure is provided in the first claw and the second claw, which is used to ensure the stability of the clamping during the clamping process of the pole, and can cooperate with the lowering structure to make the pole descend smoothly to avoid tilting of the pole. Scratches; the first claw drives the second claw to rotate through the connecting rod, and the first claw and the second claw rotate toward the middle. At this time, the clamping seat engages the spur gear to ensure that the first rotating wheel is stationary, and then the pole is clamped under the action of the first rotating wheel. In addition, when the pole is lowered in the later stage, the clamping force of the first claw and the second claw is reduced. The first claw and the second claw only play a guiding role to avoid tilting when the pole is below. The oil inlet of the claw cylinder can only reduce the pressure and cannot be directly cut off. The first claw and the second claw must always have clamping force to ensure automatic contraction when the pole diameter changes, and continuously maintain the stability and centering of the pole.

[0012] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion. The swing arm ends up being rotated with the push rod to the left of the swing arm. The swing arm ends being rotated with the push rod to the right of the swing arm. The cooperation of the pin rod is used to drive the swing bracket to rotate, which is used to clamp the electric pole. The swing bracket is rotatably connected with a driving wheel, and the two driving wheels are used to clamp the electric pole. A hydraulic motor is fixed in the swing bracket, and the output shaft of the hydraulic motor is fixedly connected to the driving wheel, which is used to drive the driving wheel to rotate and complete the downward transportation of the electric pole; the output shaft of the push rod cylinder pushes the guide plate to move, and drives the push-pull rod to move outward with the cooperation of the oblique waist groove and the second pin rod. The push-pull rod drives the swing bracket to rotate toward the middle through the cooperation of the give way groove and the third pin rod, and then the two driving wheels complete the clamping of the electric pole, and then the hydraulic motor drives the driving wheel to rotate. The two driving wheels can drive the electric pole to move downward. The driving wheel is made of rubber to ensure that there is sufficient friction to drive the electric pole to move, and will not scratch the electric pole, and slowly place the electric pole in the hole.

[0013] In a possible design, the constraint structure includes an arcuate groove arranged in the first clamping claw, a plurality of circular shafts are rotatably connected in the arcuate groove through the base, the outer walls of the plurality of circular shafts are fixedly sleeved with a first rotating wheel, a spur gear is fixed to one end of the circular shaft, a plurality of circular grooves are provided in the first clamping claw, a sliding seat is slidably connected in the circular groove, a push rod is fixed on one side of the sliding seat, one end of the push rod slides and extends into the arcuate groove and is fixed with a clamping seat, and the clamping seat cooperates with the spur gear to brake the circular shaft and the first rotating wheel, so that the first rotating wheel can clamp the electric pole, a spring is fixed to the end of the sliding seat away from the clamping seat through a spring seat, and the other end of the spring is fixedly connected to the inner wall of one side of the circular groove through the spring seat, and the spring can drive The clamping seat is always matched with the spur gear. A first magnet is fixed on the side of the sliding seat close to the spur gear, and an electromagnet is fixed on the inner wall of the circular groove close to the spur gear. A repulsive force is generated between the electromagnet and the first magnet, which is used to drive the clamping seat to release the brake on the spur gear, so that when the driving wheel drives the electric pole to move downward in the later stage, the electric pole can be prevented from being scratched by the first claw and the second claw; the clamping seat is engaged with the spur gear under the elastic force of the spring, so that the first rotating wheel is stationary. When the first claw and the second claw approach each other, the first rotating wheel in the first claw and the second claw can clamp the electric pole to avoid hard contact between the first claw, the second claw and the electric pole. In addition, when the electric pole moves downward in the later stage, the first claw, the second claw and the electric pole can also be prevented from being scratched.

[0014] In one possible design, the constraint structure also includes a second rotating wheel fixed on one side of the spur gear, and the second rotating wheel is coaxial with the spur gear. A U-shaped plate is fixed to the bottom of the push rod, and the second rotating wheel is located inside the U-shaped plate. A brake pad is fixed to the inner wall of one side of the U-shaped plate. The brake pad cooperates with the second rotating wheel to increase the friction force applied to the circular shaft during rotation, thereby preventing the pole from directly sliding down under its own gravity when the driving wheel drives the pole downward in the later stage.

[0015] In one possible design, a first connecting ear is fixed to one side of the drill barrel, and the first connecting ear is rotatably connected to the end of the mechanical arm at the top of the crane.

The motor can drive the bracket plate to rotate through the cooperation of the worm wheel and the worm, so as to adjust the angle of the electric pole, and two support seats are fixed on the side of the bracket plate away from the rotary support, which are used to limit the support of the electric pole when clamping the electric pole.

[0017] In one possible design, the repulsive force between the electromagnet and the first magnet is greater than the elastic force of the spring, which is used to release the clamping seat from the spur gear and enable the second rotating wheel to cooperate with the brake pad to increase the resistance to the rotation of the first rotating wheel.

[0018] In one possible design, a rotating rod is rotated through the second connecting ear, and a protective plate is fixed to the bottom end of the rotating rod for protecting the drill bit to prevent the worker from being injured by contact with the drill bit. A support rod is fixed to the top of the protective plate, and an arc plate is fixed on the side of the two support seats away from each other. The arc plate is coaxial with the worm gear, and the arc plate cooperates with the support rod to support the support plate when the protective plate rotates to the direction of the bracket plate to prevent the clamping structure in the bracket plate from tilting when clamping the electric pole. A strip groove is provided on one side of the drill barrel, and a device fixedly connected to the lifting plate is slidably connected in the strip groove. The first pin rod, the outer wall of the rotating rod is provided with a spiral groove, the top and bottom of the spiral groove are provided with vertical grooves, the first pin rod slides in cooperation with the spiral groove and the vertical groove; when the lifting plate drives the first pin rod to move downward and enters the vertical groove from the spiral groove, it can drive the protective plate to rotate 90° and rotate out from under the drill bit to avoid the drill bit colliding with the protective plate when moving downward; when the lifting plate drives the first pin rod to move upward and moves from the spiral groove to the vertical groove, the drill bit completes the upward movement and contraction, and the rotating rod drives the protective plate to rotate to the bottom of the bracket plate, and the support rod just supports the adjacent arc plate, supports the bracket plate, and avoids the clamping structure in the bracket plate from tilting when clamping the electric pole.

[0019] Beneficial effect: In the present invention, one side of the bracket plate is slidably connected to two push-pull rods, and a second pin is fixed inside one end of the two push-pull rods close to each other, and two oblique waist-shaped grooves are provided in the guide plate, and a yield groove is provided in the two push-pull rods, and a third pin slides in the yield groove, and the third pin is fixed in the swing bracket, and the swing bracket is rotatably connected with a driving wheel; the push rod cylinder pushes the guide plate to move, and drives the push-pull rod to move outward under the cooperation of the oblique waist-shaped groove and the second pin, and the push-pull rod drives the swing bracket to rotate toward the middle through the cooperation of the yield groove and the third pin, and then the two driving wheels complete the clamping of the electric pole, and the hydraulic motor drives the driving wheel to rotate, and the two driving wheels can drive the electric pole to move downward, and slowly place the electric pole in the hole to avoid scratches on the electric pole;

In addition, when the electric pole is lowered in the later stage, the brake on the first rotating wheel is released, so that the electric pole can move down stably and avoid hard friction between the first claw, the second claw and the electric pole, thereby ensuring the integrity of the first claw, the second claw and the electric pole, and can also guide the lowered electric pole;

[0021] When the lifting plate drives the first pin rod to move downward and enters the vertical groove from the spiral groove, the rotating rod drives the guard plate to rotate 90 degrees and rotate out from under the drill bit to avoid collision with the guard plate when the drill bit moves downward. When the lifting plate drives the first pin rod to move upward and moves from the spiral groove into the vertical groove, the rotating rod drives the guard plate to rotate to the bottom of the bracket plate, and the support rod just supports the adjacent curved plate, supports the bracket plate, and avoids the clamping structure in the bracket plate from tilting when clamping the electric pole.

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] In one embodiment: refer to Figures 1-14 The utility model relates to the technical field of power grid engineering equipment. The utility model mainly comprises a crane 1, a drilling rig 2, a drill barrel 3, a clamping structure, a lowering structure and a constraint structure.

[0040] Reference Figure 1-Figure 3 and Figure 6 Crane 1 serves as the support and mobile foundation for the entire intelligent bar grabber, with a robotic arm mounted on top. The distal end of the robotic arm is pivotally connected to the drill barrel 3 via a first connecting lug 4, enabling rotational adjustment within a certain range. A second connecting lug 9 is fixed to one side of the drill barrel 3, which is fixedly connected to a connecting bracket 17, thereby connecting the drill barrel 3 to the drilling rig 2.

[0041] Reference Figure 3 The drilling rig 2 comprises a drill barrel 3, a drill bit 7, and a rotating shaft 6. A lifting plate 5 is mounted within the drill barrel 3 and slides up and down within the drill barrel 3 via a threaded rod 8. The threaded rod 8 is driven by a motor, thereby driving the lifting plate 5 up and down within the drill barrel 3. The rotating shaft 6 rotates at the bottom of the lifting plate 5, and the drill bit 7 is fixed to the bottom end of the rotating shaft 6. When the motor drives the threaded rod 8 to rotate, the lifting plate 5 drives the rotating shaft 6 and drill bit 7 up and down. Simultaneously, the motor drives the drill bit 7 to rotate via the rotating shaft 6, thereby completing the drilling operation.

[0042] Reference Figure 6 and Figure 10-13 The clamping structure is disposed within the support plate 21 and is used to clamp the electric pole. The clamping structure includes a first claw 31 and a second claw 32 that are pivotally connected within the support plate 21 via a pin. A claw cylinder 33 is pivotally connected within the support plate 21, and the output shaft of the claw cylinder 33 is pivotally connected to one end of the first claw 31. The adjacent ends of the first and second claws 31, 32 are pivotally connected via a connecting rod 34. When the output shaft of the claw cylinder 33 is extended or retracted, it drives the first and second claws 31, 32 to rotate synchronously, thereby clamping or releasing the electric pole.

[0043] Reference Figure 12 and Figure 13 In order to ensure the stability and centering of the clamping, a constraint structure is provided in both the first clamping claw 31 and the second clamping claw 32. The constraint structure includes an arc-shaped groove 35 provided in the first clamping claw 31, and a plurality of circular shafts 36 are rotatably connected to the arc-shaped groove 35 through a base. A first rotating wheel 37 is fixedly sleeved on the outer wall of the circular shaft 36, and a spur gear 38 is fixed to one end of the circular shaft 36. A circular groove 39 is provided in the first clamping claw 31, and a sliding seat 40 is slidably connected to the circular groove 39. A push rod 44 is fixed to one side of the sliding seat 40, and one end of the push rod 44 slides and extends into the arc-shaped groove 35 and is fixed with a clamping seat 45. The clamping seat 45 cooperates with the spur gear 38 to brake the circular shaft 36 and the first rotating wheel 37, so that the first rotating wheel 37 can clamp the pole. A spring 41 is fixed to the end of the sliding seat 40 away from the clamping seat 45 via a spring seat. The other end of the spring 41 is fixedly connected to the inner wall of one side of the circular groove 39 via the spring seat. (The parameters of spring 41 range from 0.5mm to 2mm in wire diameter, 5mm to 20mm in outer diameter, 10mm to 50mm in free length, and 10N / mm to 10N / mm in stiffness.) Spring 41 drives the clamping seat 45 to always engage the spur gear 38, ensuring stable clamping. Furthermore, a first magnet 42 is fixed to the side of the sliding seat 40 near the spur gear 38, and an electromagnet 43 is fixed to the inner wall of the circular groove 39 near the spur gear 38. The repulsive force between the electromagnet 43 and the first magnet 42 drives the clamping seat 45 to release the brake on the spur gear 38, preventing the pole from rubbing against the first and second clamping claws 31 and 32 when the drive wheel 29 later moves the pole downward.

[0044] Reference Figure 13The constraint structure also includes a second rotating wheel 46 fixed to one side of the spur gear 38, and the second rotating wheel 46 is coaxial with the spur gear 38. A U-shaped plate 47 is fixed to the bottom of the push rod 44, and the second rotating wheel 46 is located inside the U-shaped plate 47. A brake pad 48 is fixed to the inner wall of one side of the U-shaped plate 47, and the brake pad 48 cooperates with the second rotating wheel 46 to increase the friction force on the circular shaft 36 when it rotates. When the electromagnet 43 is energized to generate a repulsive force, the holder 45 is separated from the spur gear 38 under the action of the repulsive force, and at the same time, the brake pad 48 contacts the second rotating wheel 46, increasing the resistance to the rotation of the first rotating wheel 37, thereby preventing the pole from directly sliding down under the action of its own gravity when the driving wheel 29 drives the pole downward in the later stage.

[0045] Reference Figure 6-Figure 9 The lowering structure is arranged in the bracket plate 21, between the two sets of clamping structures, and is used to place the electric pole smoothly and intactly in the hole in the ground. The lowering structure includes a push rod cylinder 22 fixed in the bracket plate 21 by bolts, and the output shaft of the push rod cylinder 22 is fixed with a guide plate 50. The guide plate 50 is slidably connected to the bracket plate 21, and two push-pull rods 25 are slidably connected to one side of the bracket plate 21. A second pin rod 24 is fixed inside the end of the two push-pull rods 25 that are close to each other. Two oblique waist-shaped grooves 23 are provided in the guide plate 50, and the two second pin rods 24 slide in the two oblique waist-shaped grooves 23 respectively. When the output shaft of the push rod cylinder 22 is extended and retracted, it can drive the guide plate 50 to rise and fall. When the guide plate 50 is raised and lowered, the movement of the push-pull rod 25 is controlled by the cooperation between the oblique waist-shaped groove 23 and the second pin rod 24. One side of the bracket plate 21 is rotatably connected to two swing brackets 28. A clearance groove 26 is provided in each of the two push-pull rods 25. The clearance groove 26 is located at the end of the push-pull rod 25 away from the guide plate 50. A third pin 27 slides in the clearance groove 26, and the third pin 27 is fixed in the swing bracket 28. The push-pull rod 25 drives the swing bracket 28 to rotate through the cooperation of the clearance groove 26 and the third pin 27, so as to clamp the electric pole. A drive wheel 29 is rotatably connected in the swing bracket 28, and the two drive wheels 29 cooperate to clamp the electric pole. A hydraulic motor 30 is fixed in the swing bracket 28, and the output shaft of the hydraulic motor 30 is fixedly connected to the drive wheel 29, so as to drive the drive wheel 29 to rotate.

[0046] Specifically, when the output shaft of the push rod cylinder 22 pushes the guide plate 50, the push-pull rod 25 moves outward in coordination with the oblique waist-shaped groove 23 and the second pin 24. The push-pull rod 25, through the coordination of the clearance groove 26 and the third pin 27, drives the swing bracket 28 to rotate toward the center, thereby clamping the pole with the two drive wheels 29. The hydraulic motor 30 then drives the drive wheels 29 to rotate, and the two drive wheels 29 can move the pole downward. The drive wheels 29 are made of rubber, ensuring sufficient friction to drive the pole without scratching it.

[0047] Reference Figure 6 The side of the connecting frame 17 facing away from the drilling rig 2 is fixedly connected to a slewing support 18. A worm gear 19 is rotatably connected to the slewing support 18, and one side of the worm gear 19 is fixedly connected to a support plate 21. A worm 20 is rotatably connected to the slewing support 18, meshing with the worm gear 19. A motor is housed within the slewing support 18 to drive the worm 20. The motor, through the cooperation of the worm gear 19 and the worm 20, drives the support plate 21 to rotate, thereby adjusting the angle of the pole.

[0048] Reference Figure 6 Two support seats 49 are fixed on one side of the bracket plate 21 away from the slewing support 18. The support seats 49 are used to limit the support of the pole when clamping the pole, ensuring the stability and centering of the pole during the clamping process.

[0049] In another embodiment: Figure 3 、 Figure 4 and Figure 14 , improved on the basis of Example 1: the drill barrel 3, as an important component of the drilling rig 2, not only provides space for the drill bit 7 to be lifted, lowered and rotated, but also integrates functional modules such as a clamping structure and a lowering structure. A strip groove 13 is provided in the drill barrel 3, and a first pin rod 14 fixedly connected to the lifting plate 5 is slidably connected in the strip groove 13. The first pin rod 14 slides with the spiral groove 15 and the two vertical grooves 16 on the outer wall of the rotating rod 10, realizing the function of driving the protective plate 11 to rotate when the lifting plate 5 is lifted. At the same time, an arc-shaped plate 51 is also fixed to one side of the support seat 49, and the arc-shaped plate 51 cooperates with the support rod 12 on the protective plate 11. When the protective plate 11 rotates to the bottom of the bracket plate 21, the support rod 12 supports the adjacent arc-shaped plate 51, thereby further supporting the bracket plate 21, and preventing the clamping structure in the bracket plate 21 from tilting when clamping the electric pole.

[0050] The protective plate 11 is rotatably connected to the bottom end of the rotating rod 10 and is used to protect the drill bit 7. When the lifting plate 5 drives the first pin rod 14 downward, the first pin rod 14 enters the vertical groove 16 from the spiral groove 15, driving the rotating rod 10 and the protective plate 11 to rotate 90 degrees and rotate out from under the drill bit 7 to prevent the drill bit 7 from colliding with the protective plate 11 when moving downward. When the lifting plate 5 drives the first pin rod 14 upward, the drill bit 7 completes its upward movement and retracts, and the rotating rod 10 drives the protective plate 11 to rotate to the bottom of the bracket plate 21. At the same time, the support rod 12 supports the adjacent arc plate 51, thereby supporting the bracket plate 21, preventing the clamping structure in the bracket plate 21 from tilting when clamping the pole.

[0051] A method for using an intelligent pole grabber comprises the following steps:

[0052] S1. Move the drilling rig 2 and the drill barrel 3 to the location where the electric pole is to be installed by means of the crane 1. Adjust the positions of the drilling rig 2 and the drill barrel 3 by means of the mechanical arm on the crane 1. When drilling is required, the threaded rod 8 is driven to rotate by the motor. The threaded rod 8 cooperates with the lifting plate 5 to drive the rotating shaft 6 and the drill bit 7 to move downward. During the downward movement, the first pin 14 cooperates with the spiral groove 15 and the vertical groove 16 to drive the rotating rod 10 and the protective plate 11 to rotate, and the protective plate 11 is moved out from under the drill bit 7 to prevent the protective plate 11 from affecting the descent of the drill bit 7. Then, the drill bit 7 is driven to rotate by the motor to complete the drilling operation. At this time, the drill barrel 3 is perpendicular to the ground.

[0053] S2. When it is necessary to place the electric pole, the staff places the electric pole vertically and puts it against the two support seats 49. The output shaft of the claw cylinder 33 drives the first claw 31 to rotate, and the first claw 31 drives the second claw 32 to rotate through the connecting rod 34. At this time, the first claw 31 and the second claw 32 rotate toward the middle. At this time, the clamping seat 45 engages the spur gear 38 to ensure that the first rotating wheel 37 is stationary, and then the electric pole is clamped under the action of the first rotating wheel 37. Then the output shaft of the push rod cylinder 22 pushes the guide plate 50 to move, and drives the push-pull rod 25 to move outward under the cooperation of the oblique waist groove 23 and the second pin rod 24. The push-pull rod 25 drives the swing bracket 28 to rotate toward the middle through the cooperation of the give way groove 26 and the third pin rod 27, and then the two driving wheels 29 complete the clamping of the electric pole.

[0054] S3. After the pole is clamped, the motor drives the threaded rod 8 to rotate in the opposite direction, causing the drill bit 7 to move upward. When the first pin 14 moves into the vertical groove 16 above the spiral groove 15, the protective plate 11 rotates to the bottom of the bracket plate 21, and the support rod 12 can abut against the curved plate 51 to support the bracket plate 21, thereby preventing the bracket plate 21 from tilting during the pole clamping process.

[0055] S4. When the pole needs to be placed in the hole, the oil inlet of the clamping jaw cylinder 33 is decompressed to reduce the clamping force of the first clamping jaw 31 and the second clamping jaw 32. The first clamping jaw 31 and the second clamping jaw 32 only serve as a guide to prevent the pole from tilting when it is placed under the hole. The oil inlet of the clamping jaw cylinder 33 can only reduce the pressure but cannot be directly cut off. The first clamping jaw 31 and the second clamping jaw 32 must always have a clamping force to ensure that the pole automatically contracts when the diameter changes, and the stability and centering of the pole are continuously maintained.

[0056] S5. Then the electromagnet 43 is energized. The repulsive force of the electromagnet 43 on the first magnet 42 is greater than the elastic force of the spring 41. The push rod 44 drives the clamping seat 45 to move outward, releasing the clamping seat 45 and the spur gear 38. The push rod 44 drives the brake pad 48 to rotate synchronously through the U-shaped plate 47. The brake pad 48 conflicts with the second rotating wheel 46. The friction between the brake pad 48 and the second rotating wheel 46 can prevent the first rotating wheel 37 from rotating too easily (to prevent the pole from moving down quickly under the action of gravity). The design of the wheel 37 can avoid hard friction between the first claw 31, the second claw 32 and the pole during the downward movement of the pole, ensuring the integrity of the first claw 31, the second claw 32 and the pole. Then the hydraulic motor 30 drives the driving wheel 29 to rotate, and the two driving wheels 29 can drive the pole to move downward. The first rotating wheel 37 and the driving wheel 29 are both made of rubber, ensuring that there is enough friction to drive the pole to move without scratching the pole. The pole is slowly placed in the hole. After the pole is lowered into place, fill and compact it.

[0057] However, as is well known to those skilled in the art, the working principles and wiring methods of the electromagnet 43, the claw cylinder 33, the push rod cylinder 22 and the hydraulic motor 30 are commonplace, and are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.
