[0033] The pile driving mechanism provided by the embodiments of the present application comprises the fixed block 1, the pile hammer 2, the limiting assembly 3 and the limiting moving assembly 4, wherein the pile hammer 2 is installed at the middle part of the fixed block 1, and is used to strike the pile body 7. The limiting assembly 3 comprises the first arc-shaped limiting plate 31 and the second arc-shaped limiting plate 32, and the limiting moving assembly 4 can drive the first arc-shaped limiting plate 31 and the second arc-shaped limiting plate 32 to move towards or away from each other. When the pile driving mechanism is used, first, the fixed block 1 is moved to above the pile body 7, and the pile body 7 is placed between the first arc-shaped limiting plate 31 and the second arc-shaped limiting plate 32, then the limiting moving assembly 4 is used to drive the first arc-shaped limiting plate 31 and the second arc-shaped limiting plate 32 to move towards each other, the pile body 7 is clamped by the first arc-shaped limiting plate 31 and the second arc-shaped limiting plate 32, and is limited, finally, the pile hammer 2 is used to strike the pile body 7. Since the first arc-shaped limiting plate 31, the first arc-shaped limiting plate 31 and the limiting moving assembly 4 are provided, the pile body 7 can be limited, the pile body 7 can be prevented from deviating and tilting, and the pile driving quality is improved.

[0034] In an embodiment, the fixed block 1 can be fixed on the mechanical arm of the excavator, and then the fixed block 1 is moved to the upper side of the pile body 7 through the mechanical arm. The first arc-shaped limiting plate 31 and the second arc-shaped limiting plate 32 are spliced, and the cross section thereof is circular.

[0035] In order to realize the movement and limiting of the first arc-shaped limiting plate 31 and the second arc-shaped limiting plate 32, the pile driving mechanism further comprises a limiting connecting assembly 5. The limiting connecting assembly 5 is connected with the fixed block 1, and the limiting moving assembly 4 is installed on the limiting connecting assembly 5.

[0036] Further, the limiting connecting assembly 5 comprises two connecting plates 51 and two fixed plates 52. The top of the two connecting plates 51 is fixed on the opposite sides of the fixed block 1 respectively, and the two fixed plates 52 are oppositely arranged and connected with the bottom of the two connecting plates 51 respectively. Preferably, the connecting plates 51 and the fixed block 1, and the connecting plates 51 and the fixed plates 52 are connected through welding.

[0037] In an embodiment, the limiting moving assembly 4 comprises limiting plates 41, limiting connecting rods 42 and moving plates 43. The number of the limiting plates 41, the limiting connecting rods 42 and the moving plates 43 is two. The two fixed plates 52 are provided with limiting grooves 53 extending along the width direction of the fixed plates 52. The two limiting plates 41 are located in the two limiting grooves 53 respectively. The two moving plates 43 are connected with the top of the two limiting plates 41 respectively. One end of the two limiting connecting rods 42 is connected with the bottom of the two limiting plates 41 respectively. The other end of one of the limiting connecting rods 42 is connected with the first arc-shaped limiting plate 31, and the other end of the other limiting connecting rod 42 is connected with the second arc-shaped limiting plate 32. Preferably, the moving plates 43 and the top of the limiting plates 41 are connected through welding, the limiting connecting rods 42 and the bottom of the limiting plates 41 are also connected through welding, and the same, the limiting connecting rods 42 and the first arc-shaped limiting plate 31 or the limiting connecting rods 42 and the second arc-shaped limiting plate 32 are also connected through welding.

[0038] The moving plates 43 are located on the upper surface of the fixed plates 52, and the lower side of the moving plates 43 is close to the upper surface of the fixed plates 52. Since the fixed plates 52 are provided with the limiting grooves 53, and the limiting plates 41 are located in the limiting grooves 53, the limiting plates 41 can move in the limiting grooves 53, and the movement of the limiting plates 41 can be limited through the limiting grooves 53.

[0039] In order to drive the limiting plates 41 to move in the limiting grooves 53, the limiting moving assembly 4 further comprises a moving driving piece 44 and a moving rod 45. The moving driving piece 44 is fixed on one of the fixed plates 52, and the moving driving piece 44 is connected with the moving rod 45. The two moving plates 43 are connected with the moving rod 45. The moving driving piece 44 drives the two moving plates 43 to move towards or away from each other through the moving rod 45.

[0040] Further, the moving driving member 44 is a driving motor, a motor base 46 is installed on the fixed plate 52, and the driving motor is installed on the fixed plate 52 through the motor base 46. The moving rod 45 is a screw rod, and an output end of the driving motor is connected with one end of the screw rod through a shaft coupling, so that the driving motor can drive the screw rod to rotate.

[0041] In an embodiment, the screw rod is a right and left thread screw rod, the screw rod has right threads (right-handed threads) and left threads (left-handed threads), the screw rod is threadedly connected with one of the moving plates 43 through the right threads, and the screw rod is threadedly connected with the other moving plate 43 through the left threads.

[0042] Since the screw rod is threadedly connected with one of the moving plates 43 through the right threads and threadedly connected with the other moving plate 43 through the left threads, in the process of driving the screw rod to rotate by the driving motor, the two moving plates 43 are driven to move towards or away from each other along the axial direction of the screw rod, so as to adjust the positions of the two moving plates 43. In the process of moving the two moving plates 43 towards or away from each other, the two moving plates 43 drive the two limiting plates 41 to move in the limiting grooves 53, one of the limiting plates 41 drives the first arc-shaped limiting plate 31 to move through one limiting connecting rod 42, the other limiting plate 41 drives the second arc-shaped limiting plate 32 to move through the other limiting connecting rod 42, so as to drive the first arc-shaped limiting plate 31 and the second arc-shaped limiting plate 32 to move towards or away from each other. The first arc-shaped limiting plate 31 and the second arc-shaped limiting plate 32 can be moved to limit different pile bodies 7, and are suitable for the use requirements of different diameters of the pile bodies 7.

[0043] In order to prevent the moving plates 43 from being separated from the moving rod 45, the limiting moving assembly 4 further comprises a limiting block 47, the limiting block 47 is located at one end of the moving rod 45, and the two moving plates 43 are located between the moving driving member 44 and the limiting block 47. Preferably, the limiting block 47 can be sleeved at one end of the moving rod 45, and the limiting block 47 is fixedly connected with the moving rod 45.

[0044] In order to prevent the outer side of the pile body 7 from being abraded, the pile driving mechanism of the embodiment of the application further comprises two rolling assemblies 6. One of the rolling assemblies 6 is connected with the inner wall of the first arc-shaped limiting plate 31, and the other rolling assembly 6 is connected with the inner wall of the second arc-shaped limiting plate 32. The two rolling assemblies 6 each comprise a rolling support 62 and a rolling wheel 61.

[0045] The rolling assembly 6 further comprises a rolling support 62, one end of the rolling support 62 of one of the rolling assemblies 6 is weldedly connected with the inner wall of the first arc-shaped limiting plate 31, and the rolling wheel 61 is rotatably connected with the other end of the rolling support 62; one end of the rolling support 62 of the other rolling assembly 6 is weldedly connected with the inner wall of the second arc-shaped limiting plate 32, and the rolling wheel 61 is rotatably connected with the other end of the rolling support 62.

[0046] Preferably, the rolling assembly 6 comprises a plurality of rollers 61 and a plurality of rolling supports 62, the number of the rollers 61 is the same as that of the rolling supports 62, and one roller 61 is rotatably connected to one end of each rolling support 62. The plurality of rolling supports 62 can be arranged at intervals along the inner wall of the first arc-shaped limiting plate 31 or the second arc-shaped limiting plate 32. A rotating shaft can be installed at the other end of the rolling support 62, and the roller 61 is installed on the rotating shaft and can rotate relative to the rotating shaft.

[0047] Since the rolling assembly 6 is arranged on the first arc-shaped limiting plate 31 and the second arc-shaped limiting plate 32, the rollers 61 of the rolling assembly 6 are in contact with the outer circumferential surface of the pile body 7, so that the pile body 7 is limited by the rollers 61 and is in a vertical state. Since the rollers 61 are in contact with the pile body 7, when the pile body 7 moves downward due to hammering, the rollers 61 and the pile body 7 are in rolling friction, thereby preventing the outer circumferential surface of the pile body 7 from being worn and ensuring the quality of the pile body 7.

[0048] When the pile driving mechanism of the embodiment of the present application is used, the fixed block 1 is first fixed on the mechanical arm of the excavator, then the fixed block 1 is moved to the upper end of the pile body 7, and the pile body 7 is located between the first arc-shaped limiting plate 31 and the second arc-shaped limiting plate 32, then the driving motor is started, the driving motor drives the screw rod to rotate, the screw rod drives the two moving plates 43 to move towards each other in the process of rotating, and then the first arc-shaped limiting plate 31 and the second arc-shaped limiting plate 32 are driven to move towards each other by the limiting plate 41 and the limiting connecting rod 42, until the rollers 61 are in contact with the pile body 7. In this way, the pile body 7 is limited to be in a vertical state, preventing the pile body 7 from deviating and tilting, etc., and improving the pile driving quality.

[0049] It should be noted that the above-mentioned “pile driving hammer 2” is prior art, which can be an existing pile hammer device for hammering the pile body 7. Specifically, the pile hammer device can be a hydraulic pile hammer device, which can realize the hammering of the pile body 7. The fixed block 1 and the mechanical arm of the excavator can be fixed by bolts or the like, and the specific fixing mode is also prior art, and the connection mode and structure are not limited in the present application. The above-mentioned “pile body 7” can refer to a steel pipe or the like.
