Description

Technical Field

[0001] This utility model relates to the field of foundation construction equipment technology, and in particular to a stable pile driving frame for foundation construction. Background Technology

[0002] In the field of construction engineering, foundation construction is a core step in ensuring the stability of building structures. Piling rigs, as key equipment in foundation construction, are primarily used to drive piles into the ground, providing reliable support for the building through the interaction between the piles and the soil. Whether in civil buildings, industrial plants, or municipal infrastructure construction, the quality of piling rig operations directly affects the foundation's bearing capacity and the overall safety of the building. They play an irreplaceable role in improving construction efficiency and ensuring project quality. As the construction industry's requirements for construction precision and stability continue to increase, higher demands are being placed on the technical performance of piling rigs. Currently, existing piling rigs need to adapt to different terrain conditions during actual construction, and some sites have insufficient ground flatness. The bases of existing piling rigs mostly use fixed support structures or simple adjustable supports. During adjustment, it is difficult to accurately control the height difference between different parts of the base, usually requiring repeated manual measurement and adjustment. This is not only cumbersome and time-consuming, but also prone to causing the entire piling rig to tilt due to insufficient adjustment precision. This tilting will cause uneven force on the pile head during driving, resulting in deviation of the pile driving direction, affecting the accuracy of foundation construction, and may even increase the safety hazards of subsequent building structures due to pile tilting. At the same time, the guide and limiting structure design of existing piling rigs is relatively simple, some only using single or double-sided guide plates for limiting. During long piles and repeated driving, the hard contact between the guide structure and the pile head can easily cause wear on the pile head, or insufficient limiting force can cause the pile head to tilt and deviate. This affects the vertical driving effect of the pile and may shorten the service life of the equipment, making it difficult to balance the requirements of guiding stability and pile head protection.

[0003] In response to this technical problem, this application proposes a stable piling frame for foundation construction. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stable pile driving frame for foundation construction. The frame uses a motor-driven bidirectional screw to adjust the height of the base, ensuring the equipment is level. Simultaneously, a handwheel, gear, and gear ring are used in conjunction to drive rollers to clamp the pile head, ensuring vertical pile driving and improving pile driving efficiency and safety.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A stable piling frame for foundation construction includes a fixed frame and a base. The outer wall of the fixed frame is fixedly connected to the upper left side of a support plate. A pulley is fixedly connected to the upper inner side of the fixed frame. A slide rail is fixedly connected to the left outer wall of the fixed frame. A sliding plate is slidably connected to the left outer wall of the slide rail. An impact block is slidably connected to the left outer wall of the sliding plate. A pile head is fixedly connected to the bottom end of the sliding plate. A fixing ring is fixedly connected to the lower outer wall of the fixed frame. A guide component is provided inside the fixing ring. A winding roller is fixedly connected to the right outer wall of the base. A first motor is provided on the right outer wall of the winding roller. A hydraulic rod is rotatably connected to the middle outer wall of the base. The other end of the hydraulic rod is fixedly connected to the right outer wall of the fixed frame. A support plate is connected to the bottom right end of the base through a drive component.

[0006] Furthermore, the guide assembly includes a rack slidably connected inside the fixed ring, a sliding block fixedly connected to one end of the rack, and a roller fixedly connected to the outer wall of the sliding block.

[0007] Furthermore, the drive assembly includes a second motor fixedly connected to the inside of the left side of the support plate, a bidirectional screw fixedly connected to the rotating end of the second motor, an auxiliary block threadedly connected to the outer wall of the bidirectional screw, and the outer wall of the auxiliary block slidably connected to the inside of the left side of the support plate.

[0008] Furthermore, a gear is rotatably connected inside the fixed ring, and the outer wall of the rack is meshed with the upper side of the outer wall of the gear.

[0009] Furthermore, a gear ring is rotatably connected inside the fixed ring, and the lower outer wall of the gear is meshed with the outer side of the gear ring.

[0010] Furthermore, a handwheel is slidably connected to the upper side of the gear, and the outer wall of the handwheel is threadedly connected to the upper side of the outer wall of the fixing ring.

[0011] Furthermore, a second rotating block is fixedly connected to the upper side of the auxiliary block, and a rotating rod is rotatably connected to the outer wall of the second rotating block.

[0012] Furthermore, the other end of the rotating rod is rotatably connected to a first rotating block, and the outer wall of the first rotating block is fixedly connected to the bottom end of the base.

[0013] This utility model has the following beneficial effects: In this invention, a motor drives a bidirectional screw to move an auxiliary block, allowing the rotating rod to adjust the height of various parts of the base through the two rotating blocks. This flexibly controls the height difference between the front and rear sides, ensuring that the device always remains horizontal. This significantly improves the stability and accuracy of the piling operation, avoids construction errors caused by equipment tilting, and improves the quality of foundation construction.

[0014] In this invention, the linkage of the handwheel, gear, and gear ring drives the rack and roller to retract synchronously and clamp the pile head. This ensures that the pile head is perpendicular to the driving direction, and the roller design does not affect the normal descent of the pile head, reducing the direct force on the equipment and improving driving efficiency and construction safety.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3This utility model provides an embodiment of a stable pile driving frame for foundation construction, comprising a fixed frame 1 and a base 8. The outer wall of the fixed frame 1 is fixedly connected to the upper left side of the support plate 9. A pulley 2 is fixedly connected to the inner upper side of the fixed frame 1. A slide rail 3 is fixedly connected to the outer left side of the fixed frame 1. A sliding plate 4 is slidably connected to the outer left side of the slide rail 3. An impact block 5 is slidably connected to the outer left side of the sliding plate 4. A pile head 6 is fixedly connected to the bottom end of the sliding plate 4. A fixed ring 7 is fixedly connected to the outer lower side of the fixed frame 1. A rack 23 is provided inside the fixed ring 7. A sliding block 24 is fixedly connected to one end of the rack 23. A roller 20 is fixedly connected to the outer wall of the sliding block 24. A winding roller 11 is fixedly connected to the outer right side of the base 8. A first motor 10 is provided on the outer right side of the winding roller 11. A hydraulic rod 12 is rotatably connected to the outer middle wall of the base 8. The other end of the hydraulic rod 12 is fixedly connected to the outer right side of the fixed frame 1. The support plate 9 is connected to the bottom right side of the base 8 via a second motor 13. The rotating end of the second motor 13 is fixedly connected to a bidirectional screw 17, and an auxiliary block 18 is threadedly connected to the outer wall of the bidirectional screw 17. The outer wall of the auxiliary block 18 is slidably connected to the inside of the left side of the support plate 9.

[0019] Specifically, during the use of the device, the rope inside the winding roller 11 is connected to the upper end of the impact block 5 via the pulley 2 and is driven by the first motor 10, causing the impact block 5 to slide up and down in front of the sliding plate 4. The sliding plate 4 slides on the slide rail 3. When pile driving is required, the winding roller 11 is driven to retract the rope, thereby raising the impact block 5. At this time, due to the damping device, the lower pile head 6 is above the ground. By releasing the tension of the winding roller 11, the impact block 5 falls quickly, impacting the pile head 6 and causing it to penetrate deep into the ground. During this process, because the base 8 occupies... With a large ground area, if the base 8 cannot maintain a stable state, deviations may easily occur during the impact of the pile head 6. Therefore, a leveling device is designed. The second motor 13 drives the bidirectional screw 17 to rotate. The rotation of the bidirectional screw 17 causes the auxiliary blocks 18 on both sides to slide to the sides, thereby causing the rotating rod 15 to rotate around the second rotating block 16. The first rotating block 14 on the other side is fixedly connected to the bottom of the base 8, thus creating a height difference. The design on both the front and rear sides can control the height difference between the front and rear sides, thereby maintaining the levelness of the device. Furthermore, because the pile head 6 is a long strip, it may deviate due to tilting during driving, making it difficult to maintain a vertical driving direction. Therefore, a guiding structure was designed. When the pile head 6 enters the fixed ring 7, the handwheel 22 can be rotated to rotate the lower gear 21, which in turn drives the outer gear ring 19 to rotate. The rotation of the gear ring 19 causes all gears 21 to rotate, and the rotation of the gears 21 drives the racks 23 on their respective upper outer walls to rotate, causing the sliding block 24 and roller 20 to retract inward, thereby clamping the pile head 6 in the middle. Because the rollers 20 are on the side, the device is not directly subjected to force, so the pressure is small and does not affect the descent of the pile head 6. During this process, the handwheel 22 is slidably connected to the gear 21, and the handwheel 22 is threadedly connected to the upper side of the fixed ring 7. Therefore, the threaded connection can maintain a stable structure for a short period of time.

[0020] Reference Figure 2 and Figure 3 A gear 21 is rotatably connected inside the fixed ring 7, and a rack 23 is meshed with the upper side of the outer wall of the gear 21. A gear ring 19 is rotatably connected inside the fixed ring 7, and the lower outer wall of the gear 21 is meshed with the outer side of the gear ring 19. A handwheel 22 is slidably connected to the upper side of the gear 21, and the outer wall of the handwheel 22 is threaded to the upper side of the outer wall of the fixed ring 7. A second rotating block 16 is fixedly connected to the upper side of the auxiliary block 18, and a rotating rod 15 is rotatably connected to the outer wall of the second rotating block 16. A first rotating block 14 is rotatably connected to the other end of the rotating rod 15, and the outer wall of the first rotating block 14 is fixedly connected to the bottom end of the base 8.

[0021] Specifically, a gear 21 is rotatably connected inside the fixed ring 7, and the outer wall of the rack 23 is meshed with the upper side of the outer wall of the gear 21. When the gear 21 rotates, it can drive the rack 23 to move horizontally, thereby adjusting the position of the sliding block 24 and the roller 20. A gear ring 19 is rotatably connected inside the fixed ring 7, and the lower outer wall of the gear 21 is meshed with the outer side of the gear ring 19. The rotation of the gear ring 19 can synchronously drive multiple gears 21 to rotate, ensuring the consistency of the movement of each rack 23 and roller 20, and ensuring a uniform clamping effect on the pile head 6. A handwheel 22 is slidably connected to the upper side of the gear 21, and the outer wall of the handwheel 22 is threadedly connected to the upper side of the outer wall of the fixed ring 7. Rotating the handwheel 22 can drive the gear 21 to rotate. At the same time, the threaded connection between the handwheel 22 and the fixed ring 7 can fix the position of the gear 21 after adjustment, maintaining the stability of the clamping state. A second rotating block 16 is fixedly connected to the upper side of the auxiliary block 18. A rotating rod 15 is rotatably connected to the outer wall of the second rotating block 16. A first rotating block 14 is rotatably connected to the other end of the rotating rod 15. The outer wall of the first rotating block 14 is fixedly connected to the bottom of the base 8. When the auxiliary block 18 moves under the action of the bidirectional screw 17, the rotating rod 15 will rotate around the first rotating block 14 and the second rotating block 16, thereby changing the height of the corresponding part of the base 8, realizing the leveling function of the device, and ensuring the stability of the piling process.

[0022] Working Principle: During pile driving, if the level of the device needs to be adjusted, the second motor 13 is started to drive the bidirectional screw 17 to rotate, causing the auxiliary blocks 18 on both sides to slide along the support plate 9 to both sides. At this time, the rotating rod 15 rotates around the second rotating block 16 and the first rotating block 14. By changing the height difference of different parts of the base 8, leveling is achieved, ensuring the overall stability of the device. When it is necessary to guide and limit the pile head 6, the handwheel 22 is turned to drive the gear 21 to rotate. The gear 21, through its meshing with the gear ring 19, drives all gears 21 to rotate synchronously, thereby driving the rack 23 and the sliding block 24 to move inward, so that the roller 20 clamps the pile head 6. The threaded connection between the handwheel 22 and the fixed ring 7 can maintain this clamping state. At the same time, the design of the roller 20 does not affect the descent of the pile head 6, and can also prevent its tilting and deviation, ensuring that the pile driving direction is vertical. In addition, the hydraulic rod 12 can adjust the tilt angle of the fixed frame 1 to adapt to different construction needs. The fixed connection between the fixed frame 1 and the support plate 9 and the large footprint of the base 8 further improve the overall stability of the device.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
