Detailed implementation manners

[0057] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0058] The purpose of the present invention is to provide a pile driver leveling device to solve the problems existing in the above-mentioned prior art. By using an adjusting longitudinal beam and an adjusting cross beam and cooperating with each adjusting cylinder, the mast assembly can be adjusted and the mast assembly can be kept horizontally stable on different terrains.

[0059] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0060] AsFigures 1 to 36 As shown in the figure, this embodiment provides a pile driver leveling device, which includes a self-propelled chassis 9 and a pile frame assembly 1 located above the self-propelled chassis 9. An adjusting longitudinal beam 6 is rotatably installed on the self-propelled chassis 9, and the rotation axis of the adjusting longitudinal beam 6 extends along the traveling direction of the self-propelled chassis 9. An adjusting cross beam 5 is rotatably installed on the adjusting longitudinal beam 6, and the rotation axis of the adjusting cross beam 5 is perpendicular to the rotation axis of the adjusting longitudinal beam 6. The pile frame assembly 1 is installed at the top position of the adjusting cross beam 5 and has an installation interval with the self-propelled chassis 9. A plurality of adjusting oil cylinders 2 are arranged around the outer peripheral sides of the positions where the adjusting longitudinal beam 6 and the adjusting cross beam 5 are located at the installation interval. The telescopic directions of the adjusting oil cylinders 2 are all vertically extended, and their tops are installed on the pile frame assembly 1, and their bottoms are movably abutted against the top surface of the self-propelled chassis 9. When the self-propelled chassis 9 travels to an uneven ground, the self-propelled chassis 9 tilts along with the inclination state of the ground. Then, by driving the corresponding adjusting oil cylinders 2 to extend and retract, the pile frame assembly 1 rotates on the adjusting longitudinal beam 6 along with the adjusting cross beam 5, and the pile frame assembly 1 and the adjusting cross beam 5 rotate on the self-propelled chassis 9 along with the adjusting longitudinal beam 6, so as to realize the adjustment of the pile frame assembly 1 and keep the pile frame assembly 1 horizontally stable under different terrains.

[0061] Preferably, four groups of adjusting oil cylinders 2 are arranged at the installation interval, and are divided into a left front oil cylinder, a left rear oil cylinder, a right front oil cylinder, and a right rear oil cylinder. The left front oil cylinder and the right front oil cylinder are located at the front side positions of the adjusting longitudinal beam 6 and the adjusting cross beam 5 along the traveling direction, and are symmetrically distributed on both sides of the positions where the adjusting longitudinal beam 6 and the adjusting cross beam 5 are located along the direction perpendicular to the traveling direction. The left rear oil cylinder and the right rear oil cylinder are located at the rear side positions of the adjusting longitudinal beam 6 and the adjusting cross beam 5 along the traveling direction, and are symmetrically distributed on both sides of the positions where the adjusting longitudinal beam 6 and the adjusting cross beam 5 are located along the direction perpendicular to the traveling direction.

[0062] As Figure 12 shown, when the ground is a flat terrain, the self-propelled chassis 9 travels parallel to the ground, and the left front oil cylinder, the left rear oil cylinder, the right front oil cylinder, and the right rear oil cylinder extend simultaneously to make the pile frame assembly 1 parallel to the self-propelled chassis 9. As Figure 16 shown, when the ground inclines to the right side along the traveling direction, by extending the left front oil cylinder and the left rear oil cylinder and retracting the right front oil cylinder and the right rear oil cylinder, the right-tilt leveling of the pile frame assembly 1 with the ground is realized. As Figure 20 shown, when the ground inclines to the left side along the traveling direction, by extending the right front oil cylinder and the right rear oil cylinder and retracting the left front oil cylinder and the left rear oil cylinder, the left-tilt leveling of the pile frame assembly 1 with the ground is realized. As Figure 25 shown, when the ground inclines along the traveling direction, by extending the left rear oil cylinder and the right rear oil cylinder and retracting the left front oil cylinder and the right front oil cylinder, the front-tilt leveling of the pile frame assembly 1 with the ground is realized. As Figure 28As shown, when the local ground surface is inclined away from the traveling direction, the left front cylinder and the right front cylinder extend, and the left rear cylinder and the right rear cylinder retract, so as to realize the backward tilting and leveling of the pile frame assembly 1 with the ground.

[0063] In a specific embodiment, the pile frame assembly 1 is equipped with an inclination sensor, the inclination sensor is electrically connected to an encoder, the encoder is electrically connected to an electro-hydraulic valve, and the electro-hydraulic valve is connected to the oil circuits of each leveling cylinder. In this way, the inclination information of the pile frame assembly 1 can be monitored by the inclination sensor, and after obtaining the inclination information through the encoder, the electro-hydraulic valve is controlled to act, and then the extension amount and retraction amount of the corresponding leveling cylinder are controlled to realize the automatic leveling of the pile frame assembly 1.

[0064] In a specific embodiment, as Figure 7 shown, the self-propelled chassis 9 includes a chassis body, and an installation through hole penetrating in the vertical direction is formed on the chassis body. Preferably, the chassis body has a frame structure, and the chassis body includes two first support beams both extending perpendicular to the traveling direction. The two first support beams are spaced apart along the traveling direction of the chassis body, and two second support beams are connected between the two first support beams. The second support beams extend along the traveling direction and are spaced apart along the direction perpendicular to the traveling direction. Each first support beam and the second support beam surround to form the installation through hole. The adjusting longitudinal beam 6 is located at the middle position inside the installation through hole, and both ends of the adjusting longitudinal beam 6 are rotatably matched with the inner wall of the installation through hole, so as to realize the rotational installation of the adjusting longitudinal beam 6 on the self-propelled chassis 9, and the left and right inclination of the pile frame assembly 1 can be realized, that is, the rotation around the X axis can be realized. Moreover, there is a first moving interval for the adjusting cross beam 5 to rotate between the inner peripheral wall of the installation through hole, so that during the synchronous rotation of the adjusting cross beam 5 and the adjusting longitudinal beam 6, the adjusting cross beam 5 can be rotated in place.

[0065] In a specific embodiment, as Figure 9 shown, longitudinal shafts 7 are rotatably inserted between both ends of the adjusting longitudinal beam 6 and the inner peripheral wall of the corresponding installation through hole respectively, so as to realize the rotational cooperation between the adjusting longitudinal beam 6 and the installation through hole, and further realize the rotational installation of the adjusting longitudinal beam 6 on the self-propelled chassis 9. Further preferably, blind holes are respectively formed at both ends of the adjusting longitudinal beam 6, through holes are respectively formed on the inner wall of the installation through hole at positions corresponding to both ends of the adjusting longitudinal beam 6, the through holes and the blind holes are coaxially distributed, and the longitudinal shafts 7 are rotatably inserted between the through holes and the blind holes, so that both ends of the adjusting longitudinal beam 6 are rotationally matched with the self-propelled chassis 9 through the longitudinal shafts 7.

[0066] In a specific embodiment, as Figure 5As shown, the adjusting cross beam 5 is in the shape of a straight cylinder coaxial with the installation through hole and extends in the vertical direction. A slot engaged with the adjusting longitudinal beam 6 is formed at the bottom of the adjusting cross beam 5. The slot is in rotational fit with the adjusting longitudinal beam 6. Among them, a transverse shaft 8 is rotationally inserted between the slot and the adjusting cross beam 5 to realize the rotational installation of the adjusting cross beam 5 on the adjusting longitudinal beam 6, so as to realize the front-back inclination of the pile frame assembly 1, that is, to realize the rotation of the Y axis. There is a second moving interval for the adjusting cross beam 5 to rotate between the rotational connection of the slot and the adjusting longitudinal beam 6 and the inner top wall of the slot. Therefore, during the relative rotation of the adjusting cross beam 5 and the adjusting longitudinal beam 6, the adjusting cross beam 5 can be rotated in place. Preferably, two first positioning holes are formed on the inner wall of the installation through hole. The two positioning holes are distributed on both sides of the adjusting longitudinal beam 6, and two second positioning holes are installed on the adjusting cross beam 5. When the adjusting cross beam 5 is in a horizontal state, the two second positioning holes correspond to the respective first positioning holes one by one. In the transportation state or when leveling is not required, a pin shaft is inserted between the first positioning hole and the second positioning hole to fix the pile frame assembly 1 and keep the pile frame assembly 1 parallel to the crawler structure 10.

[0067] In a specific embodiment, as Figure 10 shown, the top end of the adjusting cross beam 5 extends upward from the installation through hole, and a slewing bearing 4 is provided between the adjusting cross beam 5 and the pile frame assembly 1. Among them, the driving reducer matched with the slewing bearing 4 is fixed on the pile frame assembly 1 and belongs to a part of the pile frame assembly 1. The outer ring of the slewing bearing 4 is connected to the pile frame assembly 1, and the inner ring is connected to the adjusting cross beam 5. The slewing bearing 4 and the adjusting cross beam 5 are coaxially distributed, and each adjusting oil cylinder 2 is coaxially arranged around the outer peripheral side of the slewing bearing 4 to realize the rotational fit connection between the pile frame assembly 1 and the adjusting cross beam 5 through the slewing bearing 4. By driving the pile frame assembly 1 with the driving reducer, the pile frame assembly 1 can be rotated 360° without the self-propelled chassis 9 moving, that is, to realize the rotation of the Z axis. Preferably, the slewing bearing 4 adopts a HSN series single-row four-point contact slewing bearing 4 and has an internal gear structure.

[0068] In a specific embodiment, as Figure 12 shown, a roller 14 is installed at the bottom end of the adjusting oil cylinder 2. The roller 14 rotates and abuts against the top surface of the self-propelled chassis 9 to realize the rotational support of the adjusting oil cylinder 2 while maintaining the parallel state of the adjusting oil cylinder 2 by driving the slewing bearing 4 to rotate through the roller 14 at the bottom of the adjusting oil cylinder 2. Among them, the adjusting oil cylinder 2 includes a cylinder body 12 extending vertically and a telescopic rod that can extend downward from the cylinder body 12. The top end of the cylinder body 12 is installed on the pile frame assembly 1, and the bottom end of the telescopic rod is installed with a roller bracket 13. The roller 14 is rotatably installed on the roller bracket 13. And to ensure the stiffness of the cylinder body 12, a reinforcing ring 11 is coaxially sleeved at the top end of the cylinder body 12, and the top surface of the reinforcing ring 11 abuts against the bottom end of the pile frame assembly 1.

[0069] In a specific embodiment, as Figure 7 shown, a track plate in an annular structure is provided on the top surface of the self-propelled chassis 9. The track plate coaxially surrounds the outer peripheral side of the slewing bearing 4, and each roller 14 is rotationally abutted against the track plate so that the roller 14 can travel along the track plate, ensuring the smooth rotation of the pile frame assembly 1. Preferably, the track plate is made of an annular brass sheet.

[0070] In a specific embodiment, as Figure 13 shown, a slewing joint 3 is connected between the adjusting cross beam 5 and the pile frame assembly 1. The slewing joint 3 is located at the axial center position of the slewing bearing 4, and the slewing joint 3 communicates between the oil circuit on the chassis body and the oil circuit of the pile frame assembly 1. Specifically, the inner ring of the slewing joint 3 is connected to the adjusting cross beam 5 and is located at the middle position of the adjusting cross beam 5, so as to be able to install the oil supply structure on the chassis body and prevent the problem of oil pipe entanglement caused by the 360° rotation of the pile frame assembly 1.

[0071] In a specific embodiment, crawler structures 10 are symmetrically installed on both sides of the chassis body along the direction perpendicular to its traveling direction. The crawler structures 10 are in contact with the ground, and the chassis body is suspended above the ground to increase the contact area with the ground through the crawler structures 10 and ensure the stability during traveling. Among them, the crawler structure 10 includes a traveling support and a crawler. A plurality of traveling wheels are installed on the traveling support, and a driving mechanism for driving the traveling wheels to rotate is installed on the traveling support. The traveling wheels are arranged in sequence along the traveling direction, and the crawler is sleeved on each traveling wheel and is in contact with the ground, so as to realize the traveling of the crawler along the ground when the driving mechanism drives the traveling wheels to rotate.

[0072] In a specific embodiment, as Figures 33 to 36 shown, a plurality of telescopic legs 15 are installed on the pile frame assembly 1. Each telescopic leg 15 surrounds the outer peripheral side of the pile frame assembly 1. By providing the telescopic legs 15, after the pile machine leveling device is located at the required position, each telescopic leg 15 extends downward from the bottom and supports on the ground, so that the crawler mechanism is suspended above the ground. Among them, the telescopic leg 15 includes a leg support connected to the pile frame assembly 1. A telescopic oil cylinder that telescopically moves in the vertical direction is provided on the leg support. The bottom of the telescopic oil cylinder is movably installed with a foot. During the working process, the telescopic oil cylinder drives the foot to move downward and abut against the ground. And during the working process, through the adjusting cross beam 5, the adjusting longitudinal beam 6 and the adjusting oil cylinder 2, specifically, the adjusting oil cylinder 2 extends and retracts to adjust the distance between the chassis body and the crawler structure 10 and the ground, and the adjusting longitudinal beam 6 and the adjusting cross beam 5 adjust the angle between the crawler structure 10 and the ground, so that the crawler structure 10 acts and fits on the ground in the corresponding situation, increasing the contact area between the entire device and the ground and enhancing its stability during use.
