Description

Technical Field

[0001] This utility model relates to the field of pipe pile construction technology. More specifically, this utility model relates to a construction device for assisting pile feeding on a pile driver. Background Technology

[0002] In rotary drilling pile installation, a rotary drilling rig is typically used to drill and pre-drill holes at the designed pile location. Then, a crane is used to lift and move the precast pipe piles at a single point, and the piles are vertically lowered after being aligned with the hole position. This pile installation method combines the advantages of bored piles and precast piles, and is well-suited for construction conditions with complex geological conditions, while reducing interference with the surrounding existing geological environment.

[0003] However, in practical applications, when using cranes to lift and align precast pipe piles, the single-point lifting method is prone to shaking due to its own movement and environmental conditions, leading to difficulties in alignment and low efficiency. This is especially true when the rotary drilling rig and crane are integrated into the same pile driving equipment, where the shaking pipe pile is very likely to collide with the existing structure of the pile driving machine, causing damage and deformation to both the pile driving machine and the pipe pile structure, seriously affecting the efficiency and quality of pile foundation construction. In addition, when the length of a single precast pipe pile is insufficient, the shaking generated by the single-point lifting structure during pile splicing on the pile driving machine can prevent the subsequent pipe pile segment from being quickly, accurately, and stably aligned and fixed with the pipe pile segment in the hole, making it difficult to guarantee the quality of pile splicing.

[0004] To solve the above problems, it is necessary to design a construction device that assists in feeding piles on the pile driver, so as to improve the construction efficiency and quality of precast pipe piles in the pile planting method during the feeding and splicing process. Summary of the Invention

[0017] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0018] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified.

Therefore, they should not be construed as limitations on this utility model.

[0019] like Figure 1-5 As shown, this utility model provides a construction device for assisting pile feeding on a pile driver. The pile driver is equipped with a pile driving platform 1, with a pile driving hole corresponding to its center. Two sets of columns 2 are spaced apart along the length of the pile driving platform 1, and are arranged opposite each other on both sides of the pile driving hole. The construction device includes: A traction mechanism 3 is disposed between the two sets of columns 2. The traction mechanism 3 includes a rotary motor 31, which is fixed on the inner side wall of one set of columns 2. The motor shaft of the rotary motor 31 is arranged along the length direction of the pile driving platform 1. A telescopic rod 32 has its fixed end coaxially fixedly connected to the motor shaft of the rotary motor 31, and its movable end facing the other set of columns. The projection of the telescopic rod 32 on the pile driving platform 1 is located on the diameter line of the pile driving hole. A reel 33 is coaxially fixedly connected to the movable end of the telescopic rod 32. A traction rope 34 has one end fixed to the reel 33 and the other end detachably connected to the bottom of the hoisted pipe pile 9. Two sets of positioning components 4 are located on the same plane and are perpendicular to each other. The projection of any set of positioning components 4 on the pile driving platform 1 is located on the diameter line of the pile driving hole. Each set of positioning components includes two positioning components 4, which are respectively fixed on the two sets of columns 2 and are coaxially opposite to each other. Each positioning component 4 includes an electric push-pull rod 41 and an arc clamp 42. One end of the electric push-pull rod 41 is fixedly connected to the inner side wall of the corresponding column 2, and the outer arc surface of the arc clamp 42 is fixedly connected to the other end of the electric push-pull rod 41. When the four arc clamps 42 move to the mutual abutment position under the action of each electric push-pull rod 41, they together form a complete ring structure that matches the outer diameter of the pipe pile 9. The controller is electrically connected to both the rotary motor 31 and the electric push-pull rod 41.

[0020] In the above technical solution, the pile driver includes a chassis system, a front end, and a rear end. The chassis system enables movement and supports the front and rear end structures. The pile driving platform 1 is erected between the front and rear ends. The front end has a control room for controlling the overall movement of the pile driver, and the rear end has a crane 8 and its associated operating platform. The crane adopts a conventional crane structure, and its boom has in-situ rotation and angle adjustment functions. Lifting equipment is installed at the top of the boom for single-point lifting of the pipe piles. The crane's power system is a hydraulic system, and a hydraulic pump is correspondingly installed on the pile driving platform. The two sets of columns serve as mounting frames for the pile driver's hydraulic pump. Thus, the construction device for assisting pile feeding on the pile driver fully utilizes the existing structure of the pile driver for layout and installation, meeting the installation position requirements and achieving the functions of assisting pile feeding and splicing without the need for additional mounting brackets.

[0021] One end of the traction rope is attached to the pipe pile. The traction rope is wound up by controlling the rotation of the reel driven by the rotary motor. During the rotation and lowering process after the crane lifts the pipe pile at a single point, the traction rope can be wound up simultaneously to traction and limit the bottom end of the pipe pile in a free (swaying) state. The traction rope is always taut, effectively avoiding collision deformation and damage caused by irregular swaying of the bottom end of the pipe pile. This ensures efficient, stable, and safe operation of processes such as pile feeding and splicing. Even for pile drivers with complex structures, the pipe pile can avoid interference with the existing structure of the pile driver by reasonably controlling the extension length of the telescopic rod at different lifting stages. After the pipe pile enters between the two sets of columns and is initially aligned with the pile hole under the joint control of the traction mechanism and the crane, the connection between the traction rope and the bottom of the pipe pile is released. By retracting the telescopic rod, the telescopic rod and the reel can be moved away from the vertical projection range of the pipe pile (the space directly above the pile hole) to avoid interfering with the continued descent of the pipe pile to the positioning components and the pile hole. The telescopic rod adopts a conventional adjustable telescopic structure. After its length is adjusted, it can be temporarily fixed at the current length position (the length will no longer change), which avoids the telescopic rod length from continuing to change under the action of external force during the traction process, thus affecting the correctness of the traction direction of the pipe pile.

[0022] The inner ring surface of the complete circular structure is adapted to the outer circumference of the pipe pile. Each arc clamp has the same structure, with each individual arc clamp being a portion of the complete circular structure divided radially into 1 / 4 equal parts. The inner arc surfaces of the two arc clamps of the two positioning components in the same group are positioned opposite each other. The electric push-pull rod is detachably connected to the corresponding column. Under the action of the controller, the electric push-pull rod can simultaneously advance, using the front arc clamp to hold the pile, thus achieving horizontal positioning and limiting of the pipe pile. When the subsequent process is pile driving, the initial position of each arc clamp is maintained. In the initial pile-holding state, the pipe pile is continuously lowered vertically under this limited position, allowing it to smoothly enter the pile hole on the ground after passing through the lower pile hole and drive to the set elevation. When the subsequent process is pile splicing, the pile is first driven until the bottom surface of the pipe pile segment on the crane abuts against the top surface of the pipe pile segment in the pile hole. Then, the electric push-pull rods are further controlled to drive the arc clamps inward to tighten and fix the current position of the pipe pile segment during hoisting, ensuring its stability in position and posture during subsequent pile splicing construction, thereby ensuring the quality of pile splicing. Simultaneous advancement of multiple electric push-pull rods enables precise alignment and lowering limit of the pipe pile (with the lower pile hole). During pile driving (lowering), individual electric push-pull rods can also be used for micro-adjustments of the pile body, improving the flexibility of pile driving posture adjustment. Conventional electric push rods can be used.

[0023] The controller is equipped with a control panel, which is electrically connected to the controller. Construction personnel can control the four push-pull rods from the control room / operating console on the pile driver. Both the controller and the control panel are integrated into the original control system in the control room / operating console (the construction device and the pile driver communicate with each other), which enables the controller to better realize the linkage control of the traction mechanism, positioning components and crane, while improving the convenience of operation and ensuring the personal safety of construction personnel.

[0024] In another technical solution, the construction device for assisting pile feeding on the pile driver has a guide groove on the inner arc surface of the arc clamp 42 along the vertical direction, and a guide wheel (not shown in the figure) is provided inside it. The guide wheel is rotatably connected to the guide groove through a horizontally set rotating shaft. The wheel surface of the guide wheel is set to face the opening surface of the guide groove and is flush with it.

[0025] Specifically, the guide wheel's surface at the corresponding guide groove opening is tangent to the opening surface of the guide groove. Therefore, the installation position of the guide wheel will not affect the contact and limiting of the arc clamp with the pipe pile. During the continued hoisting and lowering of the pipe pile, the guide wheel rotates synchronously under the frictional force of the pipe pile moving relative to the arc clamp, which plays a forward guiding role in the direction of pile driving. At the same time, it transforms the original sliding friction into rolling friction, effectively reducing the friction between the pipe pile and the positioning component (arc clamp), which is conducive to the smooth and efficient driving of the guided pile.

[0026] In another technical solution, the construction device for assisting pile feeding on the pile driver includes a traction rope 34 that is detachably connected to the bottom of the pipe pile 9 via a connecting mechanism. The connecting mechanism includes two track beams 51, which are staggered on the same plane and fixedly connected to form a cross-shaped track structure; two sets of limiting posts 52, which are correspondingly set on the two track beams 51. Each set of limiting posts 52 includes two limiting posts, which are oppositely set at both ends of the corresponding track beam 51. Each limiting post 52 is set perpendicular to the plane where the cross-shaped track structure is located and slides along the length direction of the track beam 51 under the action of the drive motor. The controller is electrically connected to each drive motor and controls it synchronously; and an ear plate 53 is fixed at the bottom center point of the cross-shaped track structure via a base. The ear plate 53 is fixedly connected to the end of the traction rope 34.

[0027] In the above technical solution, the connecting mechanism achieves a detachable connection with the bottom of the pipe pile through the synchronous inward / outward movement of each limiting post. During actual construction, the top surface of the cross-shaped track structure is aligned with the bottom end face of the pipe pile, and then each limiting post is controlled to move inward synchronously to tighten until each limiting post presses against the bottom outer periphery (side) of the pipe pile, thus achieving rapid centering connection and relative fixation between the connecting mechanism (traction rope) and the pipe pile. When it is necessary to disconnect the traction rope from the pipe pile, the connecting mechanism can be completely removed from the bottom of the pipe pile by controlling each limiting post to move outward synchronously to release the pipe pile.

[0028] Specifically, each limiting post is a cylindrical structure, and the length of each track beam does not exceed the distance between the two sets of posts. A track is embedded in the top surface of the track beam, and each limiting post is slidably connected to its corresponding track. A rack is fixed along the length direction on the bottom or side surface of the track. A gear is located at the bottom of each limiting post, corresponding to and meshing with the rack. The gear is rotatably connected to the limiting post via a rotating shaft. A drive motor is fixed at a suitable position at the bottom of the limiting post (if there is no installation space inside the track, an installation slot can be opened at the bottom of the limiting post to install the drive motor inside the limiting post). The output shaft of the drive motor is fixedly connected to the rotating shaft to drive the rotating shaft to rotate, thereby rotating the gear and causing the limiting post to move relative to the rack. A small drive motor can be used, which is electrically connected to the controller. Each limiting post is initially positioned equidistant from the center point of the cross-shaped track structure on its corresponding track beam. Under the control of the controller, each drive motor operates synchronously, causing the limiting posts to move synchronously (approaching / moving away) from the center point on the track beam. Thus, the limiting structure formed by the four limiting posts can accommodate various pipe pile diameters while ensuring that the center point of the connection structure is always located on the pipe pile axis. This means the traction rope fixing point at the center point is always on the pipe pile axis, facilitating faster alignment of the pipe pile with the center of the driving hole / positioning component and further improving the accuracy of the traction mechanism in guiding and pulling the pipe pile. Furthermore, the connection mechanism is easy and quick to assemble and disassemble, eliminating the need for additional traction rope connection points on the pipe pile. Even in multi-segment construction, repeated disassembly and assembly of the traction rope is unnecessary, effectively improving the overall efficiency of pipe pile construction.

[0029] In another technical solution, the construction device for assisting pile feeding on the pile driver includes an electric telescopic rod that is electrically connected to the controller. This allows for precise control of the telescopic rod's length, controlling the reel to move precisely to the axis position (directly above) of the pile hole based on the fixed horizontal distance between the column and the pile hole and the designed length of the traction mechanism. This reduces the subjective errors that can occur when manually adjusting the telescopic rod's length, further improving the alignment accuracy between the pipe pile and the pile hole, as well as the various positioning components.

[0030] In another technical solution, the construction device for assisting pile feeding on the pile driver further includes a posture sensor, which is mounted on the traction rope and electrically connected to the controller. The posture sensor (not shown in the figure) can be fixed to the end of the traction rope near the pile. The attitude sensor is used to measure the verticality of the traction rope. After the electric telescopic boom is precisely moved to the axis position of the pile hole and the connection between the traction rope and the pipe pile is completed, the verticality of the traction rope can be used as a reference value to determine whether the crane boom has rotated and adjusted (angle) to the correct position. When the controller determines that the traction rope is in a completely vertical state based on the real-time detection data of the attitude sensor, it can be determined that the boom has lifted the pipe pile and moved it directly above the pile hole. Subsequently, the pipe pile can be lowered vertically by controlling the lifting equipment on the boom. When the traction rope is not in a vertical state, the attitude data measured by the attitude sensor can also be used as a reference for adjusting the boom's rotation angle and longitudinal angle. This is beneficial for monitoring and judging the real-time lifting status of the pipe pile and for further fine-tuning the position of the pipe pile. It avoids subjective judgment deviations that are easy to occur when manually visually aligning the pile and also avoids problems such as low pile feeding efficiency caused by repeated adjustments to the pipe pile position due to inaccurate alignment.

[0031] In another technical solution, the construction device for assisting pile feeding on the pile driver also includes a suspension bracket 6, which is fixed on the side wall of a group of columns that is not adjacent to another group of columns. The suspension bracket 6 has an L-shaped structure, with one end of its horizontal part fixed to the group of columns and the vertical part fixedly connected to the top of the other end of the horizontal part. The base includes a base plate 54, which is positioned directly below a track beam 51 at a parallel interval. The distance between the base plate 54 and the track beam 51 is equal to the thickness of the vertical section. A connecting block 55 is disposed between the track beam 51 and the base plate 54 and fixes the two together. The connecting block 55 is located at the bottom center point of the cross-shaped track structure, and the length of the connecting block 55 is less than the length of the base plate 54.

[0032] In the above technical solution, the connecting block and the base plate are both centered with the cross-shaped track structure (the center points of each component are aligned), and the ear plate is fixed at the bottom center of the base plate. Through the design of the base plate and the connecting block, a U-shaped groove is formed between the base plate and the corresponding track beam. The width of the groove (i.e., the distance between the base plate and the track beam) is adapted to the thickness of the vertical part of the suspension bracket. When the connecting mechanism is not in use, it can be temporarily stored by the suspension bracket, at which time the vertical part fits perfectly into the U-shaped groove.

[0033] In another technical solution, the construction device for assisting pile feeding on the pile driver includes a pressure sensing device 7 fixedly embedded on the inner arc surface of the arc clamp 42 or the inner sidewall of the limiting post 52, with its pressure sensing surface flush with the corresponding inner arc surface or inner sidewall. The pressure sensing device can be a pressure sensor, electrically connected to the controller. Therefore, when using the arc clamp to grip the pile or when using the connecting mechanism to dock with the bottom of the pipe pile, the direction of the current unbalanced force can be determined by the difference in readings of the pressure sensing devices on different arc clamps / different limiting posts. This allows for fine-tuning of the pipe pile's posture by adjusting the position of a single arc clamp, or ensuring the alignment accuracy and connection stability of the connecting mechanism relative to the bottom face of the pipe pile by adjusting the position of the connecting mechanism relative to the pipe pile's bottom face.

[0034] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
