A piling device for slope construction

Abstract

This invention discloses a piling device for slope construction, specifically relating to the technical field of piling equipment. It includes a support frame with a piling assembly mounted on it. The piling assembly comprises a centering cylinder, an mounting cylinder, a support plate, a convex tooth block, a rotating rod, a gear, a toothed rod, a spring, a central cylinder, a slip ring, and a guide plate. The centering cylinder is fixed to the bottom of the inner cavity of the support frame. This invention uses a gear to drive the pile body to rotate and cut the slope soil, loosening gravel and hard soil layers to reduce soil penetration resistance. Simultaneously, downward pressure drives the gear to move downwards, compressing the spring so that the concave cavity repeatedly contacts and rebounds with the convex tooth block, generating a high-frequency periodic impact force. Rotation and soil loosening reduce the load on the impact-driven soil penetration, while the impact enhances the rotational cutting effect. The synchronous coupling of these two processes solves the problems of slow soil penetration and easy pile jamming associated with single-mode methods. It is particularly suitable for complex geological conditions with alternating soft and hard slopes, significantly shortening the construction cycle and improving operational efficiency.

Description

Technical Field

[0001] This invention relates to the field of piling equipment technology, and more specifically, to a piling equipment for slope construction. Background Technology

[0002] In the construction of slope engineering projects such as water conservancy and highways, protective piles need to be driven into the slope to reinforce the slope and prevent landslides and collapses. The construction environment is generally characterized by large changes in slope, alternating soft and hard soil layers, and the presence of gravel / weathered rock, which places high demands on the efficiency of pile driving equipment in entering the soil, the accuracy of pile formation, and the adaptability to working conditions.

[0003] Existing slope piling equipment mostly adopts a single impact or single rotation operation mode, which has obvious functional limitations. For example, the patented equipment with announcement number CN222008903U only ensures the verticality of the pile through the guide structure, and cannot achieve synchronous coupling of rotation and impact. This results in high soil penetration resistance and low construction efficiency. During the piling process, the pile body is prone to horizontal displacement due to impact, and the displacement problem is more prominent when constructing on the slope surface, making it difficult to guarantee the accuracy of pile formation. At the same time, the impact load is mostly rigidly transmitted, which can easily cause pile head cracking and pile body bending. Moreover, the key components of the equipment are severely worn by strong vibration, resulting in a short service life. In addition, existing equipment is difficult to adapt to slopes with different gradients and complex geological conditions, has poor versatility, and requires frequent equipment replacement or process adjustment, which further affects the construction progress. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a piling device for slope construction, which aims to solve the problems mentioned in the background art.

[0005] The present invention provides the following technical solution: a piling device for slope construction, comprising a support frame, wherein a piling assembly is provided on the support frame; The piling assembly includes a centering cylinder, a mounting cylinder, a support plate, a toothed block, a rotating rod, a gear, a rack, a spring, a central cylinder, a slip ring, and a guide plate; The centering cylinder is fixed to the bottom of the inner cavity of the support frame, the mounting cylinder is slidably assembled to the top of the inner cavity of the support frame, and the mounting cylinder is fixedly connected to the support plate in the middle. A toothed block is embedded on one side of the pallet, and a rotating rod is movably connected to the middle of the toothed block, so that the rotating rod can move up and down relative to the toothed block and rotate circumferentially. The bottom end of the rotating rod is fixed with a gear, the outer side of the gear meshes with a rack, the rack is vertically set, and the gear always maintains meshing with the rack during the up and down movement; A recessed cavity is formed at the top of the gear, and a spring is sleeved on the outside of the rotating rod. The top end of the spring abuts against the bottom of the convex tooth block, and the bottom end abuts against the top of the gear. The central cylinder is fixed at the top of the inner cavity of the centering cylinder, the slip ring is slidably sleeved on the outside of the central cylinder, and there are multiple guide plates distributed in a ring at the bottom of the central cylinder. Each guide plate is hinged to the central cylinder at one end and to the slip ring at the other end through a hinge. When the slip ring slides along the axial direction of the central cylinder, it causes the guide plate to deflect and converge to clamp the positioning pile.

[0006] Furthermore, the piling assembly also includes a pressure column, a rubber pad, and a piling head; The pressure column is fixed to the bottom of the gear, the rubber pad is embedded inside the pressure column, and the pile head is assembled at the bottom of the rubber pad.

[0007] Furthermore, multiple clamping rods are fixed to the bottom of the rubber pad. These clamping rods are arranged in a ring and extend to the middle of the pile head to clamp the top of the pile body and achieve the positioning of the pile body within the pile head.

[0008] Furthermore, a motor is fixed to one side of the top of the pallet, and the output end of the motor is connected to the top of the rack for driving the rack to rotate; Multiple miniature electric push rods are hinged to the outer side of the central cylinder. The output end of each miniature electric push rod is hinged to a slip ring to drive the slip ring to slide axially. Two hydraulic rods are symmetrically hinged to the side wall of the centering cylinder. The top of each hydraulic rod is hinged to the outer wall of the mounting cylinder to drive the mounting cylinder to slide up and down along the support frame.

[0009] Furthermore, a base plate is hinged to one side of the bottom of the support frame, and a telescopic rod is hinged between the base plate and the other side of the bottom of the support frame. The tilt angle of the support frame relative to the base plate is adjusted by extending and retracting the telescopic rod.

[0010] Furthermore, a column is fixed on the base plate, a deflection plate is hinged to the top of the column, a deflection cylinder is hinged to the side wall of the column, and the output end of the deflection cylinder is hinged to the deflection plate, which is used to drive the deflection plate to deflect around the top of the column.

[0011] Furthermore, a fixed connecting seat is fixed on the top of the deflection plate, and two pile-feeding clamps are symmetrically arranged on the connecting seat to clamp the pile body. When the deflection plate deflects, it drives the pile-feeding clamps and the pile body to be transported to the central axis of the centering cylinder.

[0012] Furthermore, the central axes of the pressure column, pile head, centering cylinder, and central cylinder coincide to ensure the coaxiality of force transmission during pile driving.

[0013] The technical effects and advantages of this invention are as follows: 1. This invention uses gears to drive the pile body to rotate and cut the slope soil, loosening gravel and hard soil layers to reduce the resistance to soil entry. Simultaneously, downward pressure drives the gears downward, compressing the springs so that the concave cavity repeatedly contacts and rebounds with the convex tooth block, generating a high-frequency periodic impact force. Rotation and soil loosening reduce the load on the impact-driven soil entry, while the impact enhances the rotational cutting effect. The synchronous coupling of these two processes solves the problems of slow soil entry and easy pile jamming associated with single-mode methods. It is particularly suitable for complex geological conditions with alternating soft and hard slopes, significantly shortening the construction cycle and improving operational efficiency. 2. During the synchronous operation of rotation and impact, the present invention continuously applies downward pressure to counteract the rebound of the pile body caused by the impact, ensuring that the impact force is transmitted vertically downward. The gear, rotating rod, and pile body are set coaxially throughout the entire process. With the annular centering constraint of the centering cylinder, central cylinder, and guide plate, the three linkages of pressure stabilization to prevent rebound, coaxial anti-sway, and centering to control displacement suppress the horizontal displacement of the pile body from multiple dimensions such as power transmission, motion trajectory, and external constraints. This effectively solves the pain points of easy tilting and inaccurate positioning when driving piles on slopes, ensuring that the pile body is vertically inserted into the soil and that the pile quality is stable and reliable. 3. The reaction force generated by the high-frequency impact of this invention is flexibly absorbed by the elastic deformation of the spring. On the one hand, this avoids pile head cracking and pile bending caused by rigid impact, adapting to the requirements of pile integrity in slope construction. On the other hand, it blocks the transmission of strong vibration to key components such as gears, motors, and support frames, reducing component wear and the probability of failure. The buffer protection protects the pile body and reduces equipment wear. In conjunction with the rotating impact system, it achieves a balance between efficient operation and safety protection, adapting to harsh outdoor working conditions on slopes and extending the service life of the equipment.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] Example 1

[0025] This embodiment discloses a piling device for slope construction, such as... Figure 1 , Figure 2 As shown, the main body of the equipment includes a support frame 1, a base plate 21, a piling assembly, and a piling angle adjustment assembly.

[0026] like Figure 2 As shown, the support frame 1 is a rectangular frame, with a base plate 21 hinged to one side of the bottom via a pin. The base plate 21 is a rectangular steel plate that is placed on the slope to provide stable support. The other side of the bottom of the support frame 1 is hinged to the base plate 21 via a telescopic rod 22. The telescopic rod 22 is an electric telescopic rod, and its telescopic length can be controlled by an electric control system to adjust the tilt angle of the support frame 1 relative to the base plate 21, adapting to slopes with a gradient of 0-45°.

[0027] Pile driving components

[0028] like Figure 4As shown, a fixed column 23 is welded onto the base plate 21, and a deflection plate 24 is hinged to its top via a bearing. A deflection cylinder 27 is hinged to the side wall of the column 23, and the output end of the deflection cylinder 27 is hinged to the side of the deflection plate 24 via a pin. A connecting seat 25 is welded to the top of the deflection plate 24, and two pneumatic pile clamps 26 are symmetrically installed on the connecting seat 25. The pile clamps 26 can clamp the pile body. During operation, the deflection cylinder 27 extends and retracts, driving the deflection plate 24 to deflect horizontally around the top of the column 23, thereby transporting the pile body clamped by the pile clamps 26 to the center position directly above the centering cylinder 2.

[0029] Piling components

[0030] The piling components are the core of the equipment, such as... Figure 1 , Figure 3 , Figure 7 As shown, it includes a centering cylinder 2, an installation cylinder 3, a power transmission unit, an impact and vibration unit, a centering and guiding unit, and a pile driving execution unit.

[0031] The centering cylinder 2 is welded and fixed to the bottom of the inner cavity of the support frame 1 and is a cylindrical structure; the mounting cylinder 3 is cylindrical and its outer wall slides against the inner wall of the support frame 1. Two hydraulic rods 20 are symmetrically hinged to the side wall of the centering cylinder 2. The top of the hydraulic rods 20 is hinged to the outer wall of the mounting cylinder 3. The extension and retraction of the hydraulic rods 20 can drive the mounting cylinder 3 to slide up and down along the support frame 1.

[0032] Power transmission unit: such as Figure 5 As shown, a support plate 4 is welded to the middle of the mounting cylinder 3. The support plate 4 is a circular steel plate with a protruding tooth block 5 embedded on one side. A through hole is opened in the middle of the protruding tooth block 5, and a rotating rod 6 is slidably connected in the through hole through a bearing. The rotating rod 6 can rotate and slide up and down in the through hole. A servo motor 15 is fixed to the top of the support plate 4 with bolts. The output end of the motor 15 is connected to the top of the rack 8 through a coupling. The rack 8 is a vertical cylindrical rack, and a gear 7 is fixed to the bottom of the rotating rod 6. The gear 7 meshes with the rack 8. The motor 15 drives the rack 8 to rotate, which in turn drives the gear 7 and the rotating rod 6 to rotate synchronously.

[0033] Shock oscillation unit: such as Figure 6 As shown, a circular cavity 9 is formed at the top of the gear 7, and the inner wall of the cavity 9 is annularly wavy. A spring 10 is sleeved on the outside of the rotating rod 6. The spring 10 is a high-strength compression spring, with its top end abutting against the bottom of the convex tooth block 5 and its bottom end abutting against the top of the gear 7. When the gear 7 moves down with the mounting cylinder 3, the spring 10 is compressed, and the cavity 9 contacts the bottom protrusion of the convex tooth block 5. Combined with the elastic deformation of the spring 10, the gear 7 and the rotating rod 6 generate high-frequency up-and-down oscillations, forming impact force.

[0034] Calm and Guidance Unit: such as Figure 2As shown, the central cylinder 16 is welded and fixed to the top of the inner cavity of the centering cylinder 2, and the slip ring 17 is slidably sleeved on the outside of the central cylinder 16. Several miniature electric push rods are annularly hinged to the outside of the central cylinder 16, and the output end of the miniature electric push rods is hinged to the side wall of the slip ring 17. Several guide plates 19 are annularly distributed at the bottom end of the central cylinder 16. The guide plates 19 are arc-shaped steel plates, with one end hinged to the central cylinder 16 and the other end hinged to the slip ring 17 through the hinge 18. When the miniature electric push rod extends, it pushes the slip ring 17 downward, causing the guide plate 19 to deflect and converge around the hinge point, forming a conical positioning cavity that clamps the outside of the pile body. When the miniature electric push rod retracts, the slip ring 17 moves upward, the guide plate 19 opens, and the pile body is released. Furthermore, a steel ball for transition can be installed at the end of the guide plate 19 so that the steel ball rubs against the pile body. The pile body is guided and positioned by the guide plate 19, while the steel ball is used to reduce its friction.

[0035] Example 2

[0036] Based on Example 1, this example discloses a piling execution unit: such as Figure 7 As shown, a pressure column 11 is welded to the bottom of gear 7. The pressure column 11 is cylindrical and has a hydraulic rubber pad 12 embedded inside. The bottom end of the rubber pad 12 is fixed to the pile head 13, which is a conical steel head. Several clamping rods 14 are welded to the bottom of the rubber pad 12. The clamping rods 14 are arc-shaped rods, distributed in a ring and extending to the middle of the pile head 13, which can clamp the top of the pile body and prevent the pile body from sliding relative to the pile head 13. The central axes of the pressure column 11, the pile head 13, the centering cylinder 2, and the central cylinder 16 are coincident, ensuring the coaxial transmission of force.

[0037] The specific working principle is as follows:

[0038] Equipment positioning and angle adjustment: Place the base plate 21 on the slope where piling is to be carried out, start the telescopic rod 22, and adjust the length of the telescopic rod 22 according to the slope to make the support frame 1 vertical or adapt to the slope inclination angle, so as to ensure that the piling direction meets the construction requirements.

[0039] Pile conveying and clamping: Start the deflection cylinder 27 to drive the deflection plate 24 to deflect to the pile stacking area, and control the pile delivery clamp 26 to clamp the pile; then the deflection cylinder 27 moves in the opposite direction, driving the deflection plate 24 to rotate, and transporting the pile to the top of the centering cylinder 2, so that the pile falls vertically to the positioning cavity enclosed by the guide plate 19.

[0040] Centering and positioning: Activate the micro electric push rod, which extends to push the slip ring 17 down along the central cylinder 16, causing the three guide plates 19 to converge towards the center, clamping the outside of the pile body, constraining the horizontal displacement of the pile body, and completing the centering and positioning; at this time, the top of the pile body extends into the pile head 13, and the clamping rod 14 clamps the top of the pile body, realizing the fixation of the pile body and the pile head 13.

[0041] Rotary impact piling: The motor 15 and hydraulic rod 20 are started synchronously. The motor 15 drives the rack 8 to rotate, which in turn drives the gear 7, rotating rod 6, pressure column 11 and piling head 13 to rotate synchronously, so that the pile body rotates into the soil and reduces the resistance to soil penetration; the hydraulic rod 20 extends, driving the mounting cylinder 3, support plate 4, convex tooth block 5 and rotating rod 6 to move down as a whole, which drives the gear 7 to move down and compress the spring 10. The concave cavity 9 contacts the bottom protrusion of the convex tooth block 5, and with the elastic rebound of the spring 10, the gear 7 and piling head 13 generate high-frequency oscillating impact force, realizing synchronous piling of rotation and impact; the rubber pad 12 buffers the impact force to avoid damage to the equipment parts.

[0042] Reset to complete the operation: After the pile is driven to the specified depth, the motor 15 is turned off, the hydraulic rod 20 is controlled to retract, and the pile driving assembly is reset; the micro electric push rod retracts, the slip ring 17 moves up, and the guide plate 19 opens to release the pile; the deflection cylinder 27 drives the pile delivery clamp 26 to reset, completing the single pile driving operation. The above steps can be repeated to drive piles continuously.

[0043] During the aforementioned pile driving process, gear 7 drives the rotating rod 6, the pressure column 11, and the pile head 13 to rotate, causing the pile to rotate synchronously during the soil penetration process. This generates a cutting and loosening effect on the slope soil, reducing the resistance of the pile entering the soil. At the same time, downward pressure causes gear 7 to move downward, compressing spring 10. The concave cavity 9 and the bottom protrusion of the convex tooth block 5 continuously contact and separate during the rotation process. Combined with the elastic rebound of spring 10, a high-frequency periodic impact is formed, allowing the pile to simultaneously obtain rotational cutting force, static pressure, and impact force. This avoids the low efficiency caused by traditional equipment that can only perform single impact or single rotation. It is especially suitable for complex geological conditions such as slopes with alternating soft and hard surfaces and containing gravel or hard soil layers, significantly shortening the construction cycle.

[0044] During the rotation and downward pressure of gear 7, the pile body is always in a state of coaxial rotation and vertical pressure. With the centering guidance of centering cylinder 2, center cylinder 16 and guide plate 19, the horizontal swaying of the pile body under impact is effectively suppressed. At the same time, the continuous downward pressure can offset the rebound of the pile body caused by the impact, ensuring that the impact force is stably transmitted downward, so that the pile body can be smoothly driven into the soil in the vertical direction. This significantly reduces the tilting and deviation problems that are prone to occur when driving piles on slopes, and improves the quality of pile formation and construction accuracy.

[0045] The impact reaction force generated during pile driving is absorbed by the elastic deformation of spring 10, avoiding the direct rigid transmission of impact load to key components such as gear 7, rotating rod 6, motor 15 and support frame 1, reducing vibration and wear, and extending the service life of the equipment; at the same time, the buffering effect prevents the pile head from cracking and the pile body from bending due to excessive single impact, which is particularly suitable for scenarios in slope construction where the integrity of the pile body is required.

[0046] The rack 8 and gear 7 are always meshed. The power transmission of gear 7 is continuous during the up-and-down movement and rotation. The concave cavity 9 and the convex tooth block 5 repeatedly contact and separate during the rotation, so that the impact action is continuous, stable and controllable, avoiding problems such as power interruption and unstable impact, and adapting to the needs of long-term and continuous operation on slopes.

[0047] The above description is merely 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.
