Description

Technical Field

[0001] This invention relates to the field of pile driving technology, and in particular to a static pile driver for composite foundations. Background Technology

[0002] Static pressure piling is a method of foundation pile construction in engineering. It involves using a static pile driver to drive precast piles into the soil, utilizing the machine's own weight and counterweights to provide the reaction force. The advantages of static pressure piling include completely avoiding the vibration, noise, and pollution caused by hammer driving, resulting in no damage to the pile, no noise, no vibration, no impact, and no pollution during construction. Most existing static pressure piling machines use a clamping mechanism to hold the pile tightly, then use the machine's own weight and counterweights to provide the reaction force to drive the precast pile into the soil. However, during the movement of the static pressure piling machine, it is difficult to ensure that the clamped pile is precisely aligned with the intended pile position, leading to a deviation between the finished pile and the pre-set position. This prevents the on-site construction from being completed accurately according to requirements. Furthermore, existing static pressure piling machines require manual assistance during rotation, posing significant safety hazards to on-site workers. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a composite foundation static pressure pile machine to address the shortcomings of the prior art.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A composite foundation static pressure pile driver includes two long supports arranged parallel and spaced along the front-back direction, a main platform, and a pile driving mechanism. The pile driving mechanism is vertically arranged between the two long supports. The main platform is arranged on the pile driving mechanism. The pile driving mechanism is connected to the main platform through a horizontal plane driving mechanism, and the horizontal plane driving mechanism can drive the main platform to rotate in the horizontal plane or move in the left-right direction relative to the pile driving mechanism. The main platform and the long supports are connected through a displacement driving assembly, and the displacement driving assembly can drive the long supports to move up and down or back and forth relative to the main platform. The pile driving mechanism can press the pile body placed therein into the soil below.

[0005] The beneficial effects of this invention are as follows: The composite foundation static pressure pile driver of this invention drives the main platform to rotate in the horizontal plane or move in the left and right direction relative to the pile driving mechanism through the horizontal plane driving mechanism, and drives the long support to move up and down or back and forth relative to the main platform through the displacement driving assembly, so as to realize the free movement of the entire device, independently complete the cross axis alignment of the pile position, so as to accurately drive the pile into the soil of the pile position below. The operation is simple and convenient, and the horizontal plane driving mechanism realizes the rotation process without the need for manual on-site assistance, which greatly improves the safety of on-site operation.

[0006] Based on the above technical solution, the present invention can be further improved as follows:

[0007] Further: The pile driving mechanism includes a pile driving bracket, a central support seat, and a pile driving assembly. The central support seat is disposed between the two long supports. The main platform has a through hole in the middle for the pile driving bracket to pass through. The central support seat is located below the through hole. The main platform is disposed on the pile driving bracket and can rotate horizontally relative to the pile driving bracket. The lower end of the pile driving bracket passes through the through hole of the main platform and is connected and fixed to the central support seat. The pile driving bracket is connected to the main platform through a horizontal driving mechanism, and the horizontal driving mechanism can drive the main platform to rotate horizontally relative to the pile driving bracket and the central support seat, or move in the left and right direction. The pile driving assembly is provided with the upper end of the pile driving bracket. The pile driving assembly can press the pile body located in the pile driving bracket into the soil below the central support seat.

[0008] The beneficial effects of the above-mentioned further solution are: the horizontal plane driving mechanism can drive the main platform to rotate horizontally circumferentially relative to the pile driving support and the central support seat, thereby realizing the rotation of the main platform and the long support seat, or, it can drive the platform to move left and right relative to the pile driving support and the central support seat, thereby realizing left and right movement. It is fully hydraulically driven, requires no manual assistance, and is very convenient and safe.

[0009] Further: The pile driving assembly includes two sets of pile driving mechanisms, a clamping beam, and a cover plate assembly. The two sets of pile driving mechanisms are symmetrically arranged on the pile driving support and located on the front and rear sides of the pile driving support. The clamping beam is slidably arranged between the front and rear sides of the pile driving support, and the front and rear ends of the clamping beam are respectively connected to the driving ends of the corresponding pile driving mechanisms. The cover plate assembly slides on the clamping beam and can slide in the left and right direction to facilitate opening or closing the clearance hole in the middle of the clamping beam for inserting the pile. The clamping beam is provided with a clamping mechanism around the clearance hole for clamping the pile and moving downward together with the pile and the clamping beam. The two pile driving mechanisms can synchronously drive the clamping beam to move downward so that the pile placed in the clearance hole is pressed into the soil below the central support when the clearance hole is closed.

[0010] The beneficial effects of the above-mentioned further solution are: by sliding the cover plate assembly on the clamping beam, the clearance hole can be opened through the cover plate assembly, thereby facilitating the placement of the pile. After the pile is placed, the clearance hole is covered by the cover plate assembly, and the pile is clamped by the clamping beam, ensuring that the pile is smoothly pressed into the soil at the pile location.

[0011] Further: The cover plate assembly includes two cover plate driving mechanisms and a cover plate. The two cover plate driving mechanisms are horizontally parallel and spaced apart on the clamping beam, and are located between one side of the cover plate and the corresponding pile driving mechanism. The cover plate is slidably disposed on the upper end of the clamping beam. The driving ends of the two cover plate driving mechanisms are respectively connected and fixed to both sides of the cover plate. The clamping mechanism is provided with a clamping mechanism for clamping the pile body and moving downward together with the pile body and the clamping beam around the clearance hole. The two cover plate driving mechanisms synchronously drive the cover plate to slide in the left and right direction to open or close the clearance hole.

[0012] The beneficial effects of the above-mentioned further solution are: by setting the cover plate driving mechanism, the cover plate can be driven to slide in the left and right direction, thereby automatically opening or closing the clearance hole to achieve safe operation. At the same time, the clamping mechanism can clamp the pile body to ensure that the pile body is smoothly pressed into the soil.

[0013] Furthermore, the clamping mechanism includes multiple clamping cylinders and clamping plates that are the same number as and correspond one-to-one with the clamping cylinders. The multiple clamping cylinders are arranged around the clearance hole in the clamping beam. The clamping plates are arranged at the driving end of the corresponding clamping cylinders, and the multiple clamping cylinders synchronously drive the corresponding clamping plates to clamp the pile body.

[0014] The beneficial effect of the above-mentioned further solution is that by setting multiple clamping cylinders around the relief hole in the clamping beam, the corresponding clamping plates can be driven simultaneously to clamp the pile in the relief hole, and it is applicable to piles of different specifications, with strong versatility.

[0015] Further: The horizontal driving mechanism includes two horizontal driving mechanisms, which are symmetrically arranged on the front and rear sides of the pile driving support. One end of each horizontal driving mechanism is rotatably connected to the main platform, and the other end is rotatably connected to the corresponding side of the pile driving support. When the displacement driving assembly drives the central support to lift off the ground, the synchronous telescopic movement of the two horizontal driving mechanisms can drive the pile driving support and the central support to move left and right relative to the main platform. When the two horizontal driving mechanisms telescopically move asynchronously, they can drive the pile driving support and the central support to rotate horizontally circumferentially relative to the main platform.

[0016] The beneficial effect of the above-mentioned further solution is that by setting the horizontal drive mechanism between the main platform and the pile driving support, when the two horizontal drive mechanisms move synchronously, they can drive the pile driving support and the central support to move left and right relative to the main platform. When the two horizontal drive mechanisms move asynchronously, they can generate rotational force to drive the pile driving support and the central support to rotate relative to the main platform, thereby facilitating the alignment of the cross axis with the pile position under pure hydraulic control.

[0017] Further: The displacement drive assembly includes four sets of lifting drive mechanisms and two sets of front and rear drive mechanisms. The long support is provided with slide rails that match the front and rear drive mechanisms along the front and rear direction. The front and rear drive mechanisms are slidably mounted on the slide rails, and the drive ends of the front and rear drive mechanisms are fixedly mounted. The main platform is connected to the corresponding front and rear drive mechanisms through four sets of vertically arranged lifting drive mechanisms around its perimeter. The lifting drive mechanisms can synchronously drive the long support to move up and down relative to the main platform and the central support. When the lifting drive mechanism drives the long support to lift off the ground, the front and rear drive mechanisms can drive the long support to move back and forth relative to the main platform and the central support.

[0018] The beneficial effects of the above-mentioned further solution are: the synchronous movement of the four sets of lifting drive mechanisms can realize the lifting movement of the long support relative to the main platform and the central support, thereby making the long support or the central support off the ground. Through the cross-lifting of the long support and the central support, in conjunction with the front and rear drive mechanisms and the horizontal plane drive mechanism, the entire device can move freely, thus facilitating the alignment of the cross axis with the pile position under pure hydraulic control.

[0019] Furthermore, a pile lifting mechanism is provided on one side of the pile driving mechanism on the main platform. The lifting sling of the pile lifting mechanism is equipped with a lifting device that is adapted to the pile body and can clamp the pile body. The pile lifting mechanism drives the lifting device and the pile body clamped by the lifting device to move above the pile driving support and puts the pile body into the pile driving mechanism.

[0020] The beneficial effects of the above-mentioned further solution are: by setting up the pile lifting mechanism and the lifting device adapted to the pile body, the pile body can be clamped relatively easily and smoothly placed into the pile driving support, realizing the integrated operation of pile lifting and pile driving, which greatly improves the operation efficiency.

[0021] Furthermore, a control room is provided on the main platform on the other side of the pile driving mechanism, and a hydraulic system is provided in the control room that is connected to the horizontal plane drive mechanism, the pile driving mechanism and the displacement drive assembly respectively.

[0022] The beneficial effects of the above-mentioned further solution are: by setting up the control room and hydraulic system, it is convenient to control the pile driving mechanism to complete the pile driving action in the control room, and the pile lifting mechanism can be used in conjunction with the pile lifting mechanism to realize the integrated operation of pile lifting and pile driving.

[0023] Furthermore, the composite foundation static pressure pile driver also includes two sets of counterweight beams, which are symmetrically arranged at both ends of the main platform.

[0024] The beneficial effects of the above-mentioned further solution are: by setting the counterweight beam, the stability of the entire static pressure pile driver can be increased, and by symmetrically setting the two sets of counterweight beams at both ends of the main platform, the force balance of the entire main platform can be guaranteed.

[0031] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0032] like Figures 1 to 4As shown, a composite foundation static pressure pile driver includes two long supports 1 arranged parallel to each other along the front-to-back direction, a main platform 3, and a pile driving mechanism. The pile driving mechanism is vertically arranged between the two long supports 1. The main platform 3 is arranged on the pile driving mechanism. The pile driving mechanism is connected to the main platform 3 through a horizontal plane drive mechanism, which can drive the main platform 3 to rotate in the horizontal plane or move in the left-right direction relative to the pile driving mechanism. The main platform 3 is connected to the long supports 1 through a displacement drive assembly, which can drive the long supports 1 to move up and down or back and forth relative to the main platform 3. The pile driving mechanism can press the pile body placed inside it into the soil below.

[0033] The composite foundation static pressure pile driver of the present invention drives the main platform 3 to rotate or move in the left and right direction relative to the pile driving mechanism in the horizontal plane through the horizontal plane driving mechanism, and drives the long support 1 to move up and down or back and forth relative to the main platform 3 through the displacement driving assembly, so as to realize the free movement of the entire device and independently complete the cross axis alignment of the pile position, so as to accurately drive the pile into the soil of the pile position below. The operation is simple and convenient, and the horizontal plane driving mechanism realizes the rotation process without the need for manual on-site assistance, which greatly improves the safety of on-site operation.

[0034] In one or more embodiments of the present invention, the pile driving mechanism includes a pile driving bracket 4, a central support seat 5, and a pile driving assembly. The central support seat 5 is disposed between two long supports 1. The main platform 3 has a through hole in the middle for the pile driving bracket 4 to pass through. The central support seat 5 is located below the through hole. The main platform 3 is disposed on the pile driving bracket 4 and can rotate horizontally relative to the pile driving bracket 4. The lower end of the pile driving bracket 4 passes through the through hole of the main platform 3 and is connected and fixed to the central support seat 5. The pile driving bracket 4 is connected to the main platform 3 through a horizontal driving mechanism, and the horizontal driving mechanism can drive the main platform 3 to rotate horizontally relative to the pile driving bracket 4 and the central support seat 5, or move in the left and right direction. The pile driving assembly is provided with the upper end of the pile driving bracket 4. The pile driving assembly can press the pile body located in the pile driving bracket 4 into the soil below the central support seat 5. The horizontal driving mechanism can drive the main platform 3 to rotate horizontally circumferentially relative to the pile driving support 4 and the central support seat 5, thereby realizing the rotation of the main platform 3 and the long support 1. Alternatively, it can drive the platform 3 to move left and right relative to the pile driving support 4 and the central support seat 5, thereby realizing left and right movement. It is fully hydraulically driven, requiring no manual assistance, which is very convenient and safe.

[0035] In one or more embodiments of the present invention, the pile driving assembly includes two sets of pile driving mechanisms 6, a clamping beam 7, and a cover plate assembly. The two sets of pile driving mechanisms 6 are symmetrically arranged on the pile driving bracket 4 and located on the front and rear sides of the pile driving bracket 4. The clamping beam 7 is slidably arranged between the front and rear sides of the pile driving bracket 4, and the front and rear ends of the clamping beam 7 are respectively connected to the driving ends of the corresponding pile driving mechanisms 6. The cover plate assembly slides on the clamping beam 7 and can slide in the left and right direction to facilitate opening or closing the clearance hole in the middle of the clamping beam 7 for inserting the pile. The clamping beam 7 is provided with a clamping mechanism for clamping the pile and moving downward together with the pile and the clamping beam 7 around the clearance hole. The two pile driving mechanisms 6 can synchronously drive the clamping beam 7 to move downward so that the pile placed in the clearance hole is pressed into the soil below the central support seat 5 when the clearance hole is closed. By sliding the cover plate assembly onto the clamping beam 7, the clearance hole can be opened through the cover plate assembly, thus facilitating the placement of the pile. After the pile is placed, the clearance hole is covered by the cover plate assembly, and the clamping beam 7 clamps the pile, ensuring that the pile is smoothly pressed into the soil at the pile location.

[0036] In one or more embodiments of the present invention, the cover plate assembly includes two cover plate driving mechanisms 8 and a cover plate 9. The two cover plate driving mechanisms 8 are horizontally parallel and spaced apart on the clamping beam 7, and are located between one side of the cover plate 9 and the corresponding pile driving mechanism 6. The cover plate 9 is slidably disposed on the upper end of the clamping beam 7. The driving ends of the two cover plate driving mechanisms 8 are respectively connected and fixed to both sides of the cover plate 9. The clamping mechanism is provided with a clamping mechanism for clamping the pile body and moving downward together with the pile body and the clamping beam 7 around the clearance hole. The two cover plate driving mechanisms 8 synchronously drive the cover plate 9 to slide in the left and right direction to open or close the clearance hole. By setting the cover plate driving mechanism 8 to drive the cover plate 9 to slide in the left and right direction, the clearance hole can be automatically opened or closed to achieve safe operation. At the same time, the clamping mechanism can clamp the pile body to ensure that the pile body is smoothly pressed into the soil.

[0037] Specifically, in one or more embodiments of the present invention, the clamping mechanism includes a plurality of clamping cylinders 10 and clamping plates 11, which are the same number as and correspond one-to-one with the clamping cylinders 10. The plurality of clamping cylinders 10 are arranged around the clearance hole in the clamping beam 7, and the clamping plates 11 are arranged at the driving end of the corresponding clamping cylinders 10. The plurality of clamping cylinders 10 synchronously drive the corresponding clamping plates 11 to clamp the pile body. By arranging the plurality of clamping cylinders 10 around the clearance hole in the clamping beam 7, the corresponding clamping plates 11 can be driven simultaneously to clamp the pile body in the clearance hole. This mechanism is applicable to pile bodies of different specifications and has strong versatility.

[0038] Here, in order to ensure that the clamping plate 11 fits better with the pile body, the side wall of the clamping plate 11 facing the pile body is an arc shape adapted to the pile body. In this way, when multiple clamping plates 11 move towards the side wall of the pile body at the same time, they can fit tightly with the outer wall of the pile body, increasing the friction between them, thereby ensuring that multiple clamping plates 11 can firmly clamp the pile body and ensure the safety of the operation.

[0039] It should be noted that in this embodiment, there are four clamping cylinders 10 and four clamping plates 11. The four clamping cylinders 10 are arranged at intervals around the clearance hole, and the included angle between two adjacent clamping cylinders 10 is 90 degrees. The four clamping cylinders 10 are arranged symmetrically in all four directions.

[0040] In practice, in order to ensure that the clamping cylinder 10 drives the clamping plate 11 to clamp the pile body more stably, multiple reinforcing ribs are provided in the clamping beam 7, and a load-bearing plate is provided at the end of the clamping cylinder 10 away from the clamping plate 11. On the one hand, this ensures that the clamping cylinder 10 is stably supported, and on the other hand, it straightens the entire clamping beam and its internal structural components so that they do not deform.

[0041] Optionally, in order to make the clamping beam 7 move downward more smoothly along the pressing bracket 4, the clamping beam 7 has a cross-shaped structure adapted to the pile pressing bracket 4, and guide wheels 19 are respectively provided on the two adjacent outer walls of each right angle formed by two adjacent directions on the clamping beam 7, and the guide wheels 19 are respectively in contact with the outer wall of the corresponding leg of the pressing bracket 4, and the guide wheels 19 can roll up and down along the corresponding outer wall.

[0042] In one or more embodiments of the present invention, the horizontal driving mechanism includes two horizontal driving mechanisms 18, which are symmetrically arranged on the front and rear sides of the pile driving support 4. One end of each horizontal driving mechanism 18 is rotatably connected to the main platform 3, and the other end of each horizontal driving mechanism 18 is rotatably connected to the corresponding side of the pile driving support 4. When the displacement driving assembly drives the central support 5 off the ground, the synchronous telescopic movement of the two horizontal driving mechanisms 18 can drive the pile driving support 4 together with the central support 5 to move left and right relative to the main platform 3. When the two horizontal driving mechanisms 18 telescopic movement is asynchronous, they can drive the pile driving support 4 together with the central support 5 to rotate horizontally circumferentially relative to the main platform 3. By setting the horizontal drive mechanism 18 between the main platform 3 and the pile driving support 4, when the two horizontal drive mechanisms 18 move synchronously, they can drive the pile driving support 4 together with the central support seat 5 to move left and right relative to the main platform 3. When the two horizontal drive mechanisms 18 move asynchronously, they can generate rotational force to drive the pile driving support 4 together with the central support seat 5 to rotate relative to the main platform 3, thereby facilitating the alignment of the cross axis with the pile position under pure hydraulic control.

[0043] In one or more embodiments of the present invention, the displacement drive assembly includes four sets of lifting drive mechanisms 12 and two sets of front and rear drive mechanisms 13. The long support 1 is provided with a slide rail that matches the front and rear drive mechanisms 13 along the front and rear direction. The front and rear drive mechanisms 13 are slidably disposed on the slide rail, and the drive end of the front and rear drive mechanisms 13 is fixedly disposed. The four sides of the main platform 3 are respectively connected to the corresponding front and rear drive mechanisms 13 through four sets of vertically arranged lifting drive mechanisms 12. The lifting drive mechanisms 12 can synchronously drive the long support 1 to move up and down relative to the main platform 3 and the central support 5. When the lifting drive mechanism 12 drives the long support 1 to leave the ground, the front and rear drive mechanisms 13 can drive the long support 1 to move back and forth relative to the main platform 3 and the central support 5. The long support 1 can be raised or lowered relative to the main platform 3 and the central support 5 by the synchronous movement of the four sets of lifting drive mechanisms 12, thereby lifting the long support 1 or the central support 5 off the ground. By the cross-lifting of the long support 1 and the central support 5, in conjunction with the front and rear drive mechanisms 13 and the horizontal drive mechanism, the entire device can move freely, thus facilitating the alignment of the cross axis with the pile position under pure hydraulic control.

[0044] Optionally, in one or more embodiments of the present invention, a pile lifting mechanism 14 is provided on one side of the pile driving mechanism on the main platform 1. The lifting sling of the pile lifting mechanism 14 is equipped with a lifting device 15 adapted to the pile body and capable of clamping the pile body. The pile lifting mechanism 14 drives the lifting device 15 and the pile body clamped by the lifting device 15 to move above the pile driving support 4 and place the pile body into the pile driving mechanism. By setting up the pile lifting mechanism 14 and the lifting device 15 adapted to the pile body, the pile body can be clamped relatively easily and placed smoothly into the pile driving support 4, realizing integrated pile lifting and pile driving operations, which greatly improves the operation efficiency.

[0045] Optionally, in one or more embodiments of the present invention, a control room 16 is provided on the main platform 1 on the other side of the pile driving mechanism. The control room 16 contains a hydraulic system 2 connected to the horizontal plane drive mechanism, the pile driving mechanism, and the displacement drive assembly. By providing the control room 16 and the hydraulic system 2, it is convenient to control the pile driving mechanism to complete the pile driving action within the control room 16. Combined with the pile lifting mechanism 14, this enables integrated pile lifting and pile driving operations.

[0046] Optionally, in one or more embodiments of the present invention, the composite foundation static pressure pile driver further includes two sets of counterweight beams 17, which are symmetrically arranged at both ends of the main platform 3. By setting the counterweight beams 17, the stability of the entire static pressure pile driver can be increased, and by symmetrically arranging the two sets of counterweight beams 17 at both ends of the main platform 3, the force balance of the entire main platform 3 can be ensured.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
