Abstract
Description
Technical Field
[0001] This utility model relates to the field of foundation pile sinking guidance technology, and in particular to a guidance device for foundation pile sinking. Background Technology
[0002] A foundation pile is a columnar structure that penetrates deep into the soil or rock strata. It can be traced back to ancient wooden and stone piles, and has been developed into reinforced concrete piles, steel piles, etc. Its core function is to transfer the building load to the deep stable strata, solve the problems of soft soil, insufficient bearing capacity or settlement risk in shallow soil, and is widely used in high-rise buildings, bridges, ports, offshore wind power and other projects. Traditional construction faces challenges such as pile position deviation, loss of verticality control and poor geological adaptability.
[0003] The existing guiding devices for pile driving only use ordinary guide tubes. When driving the piles, the piles descend too quickly due to their own weight, which can easily cause the pile heads to collide and be damaged, increasing maintenance costs and safety hazards. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] The present invention discloses a guiding device for foundation pile sinking, which is mainly applied to scenarios where existing foundation pile sinking guiding devices are prone to collision and damage to the pile head due to excessive speed during foundation pile sinking.
[0029] Reference Figures 1-4 A guiding device for foundation pile driving, comprising:
[0030] Support 4, a fixed platform 3 is fixedly connected to the upper side of support 4, and the same guide tube 8 is slidably connected to the inside of the opposite side of support 4 and fixed platform 3. A rubber ring 16 is fixedly connected to the lower side of guide tube 8.
[0031] The fixed base 2 is fixedly connected to the upper side of the fixed platform 3, and the upper side of the fixed base 2 is equipped with a crane 1;
[0032] Fixing plates 15, multiple fixing plates 15 are fixedly connected to the outer wall of guide tube 8 at equal intervals;
[0033] Lifting cylinder 10, two lifting cylinders 10 are fixedly connected at equal intervals to the lower side of the fixed platform 3, the guide tube 8 is located between the two lifting cylinders 10, the lower side of the two lifting cylinders 10 is fixedly connected to the connecting plate 9, and the other end of the two connecting plates 9 is fixedly connected to the outer wall of the guide tube 8.
[0034] The buffer components 17 are arranged at equal intervals inside the guide tube 8. The buffer components 17 are used to slow down the speed of the foundation pile during sinking and to prevent the pile head from colliding and causing damage.
[0035] Reference Figure 4 and Figure 5 In a preferred embodiment, the buffer component 17 includes:
[0036] Partition 1701, two partitions 1701 are fixedly connected to the inner wall of the fixed plate 15 at equal intervals. The two partitions 1701 are located inside the fixed groove opened on the opposite side of the guide tube 8 of the fixed plate 15. The two partitions 1701 are provided with a sliding groove on the opposite side. The same U-shaped buffer plate 1702 is slidably connected inside the sliding groove.
[0037] Two buffer springs 1703 are fixedly connected at equal intervals to one side of the U-shaped buffer plate 1702, and the other ends of the two buffer springs 1703 are fixedly connected to the same fixed plate 15.
[0038] Compression spring 1704, multiple compression springs 1704 are fixedly connected at equal intervals to the opposite ends of the other side of the U-shaped buffer plate 1702, and the other ends of the multiple compression springs 1704 located at both ends are respectively fixedly connected to ratchet plates 1705.
[0039] In this scheme, buffer component 17 also includes:
[0040] The rotating rod 1708 is connected to the rotating holes on both sides of the inner wall of the U-shaped buffer plate 1702 via bearings, and the outer wall of the rotating rod 1708 is fixedly connected to the roller 1706.
[0041] Buffer dial 1707, two buffer dials 1707 are fixedly connected to the outer wall of rotating rod 1708 at equal intervals, and roller 1706 is located between the two buffer dials 1707.
[0042] During the pile driving process, by setting up buffer spring 1703, compression spring 1704, ratchet plate 1705, roller 1706, and buffer wheel 1707, the outer wall of the pile is in direct contact with the roller 1706 under the action of buffer spring 1703 and roller 1706, which will not damage the anti-corrosion coating of the outer wall. The rotation of roller 1706 drives the two buffer wheels 1707 to continuously move the ratchet on the ratchet plate 1705 in contact with it. Due to the friction between the ratchet plate 1705 and the buffer wheel 1707, a certain resistance is generated to the rotation of roller 1706, which slows down the speed of the pile when it falls and prevents the pile head from colliding and being damaged due to excessive falling speed.
[0043] Reference Figures 1-3 In a preferred embodiment, hollow sliding plates 6 are fixedly connected to both sides of the fixed base 2. The lower sides of the two hollow sliding plates 6 are fixedly connected to the upper side of the fixed platform 3. Guide rail grooves are opened inside the two hollow sliding plates 6. Rotating holes are opened on both sides of the two hollow sliding plates 6. Lead screws 14 are connected to the two rotating holes through bearings. The same transmission belt 11 is provided at one end of the two lead screws 14 on the same side. The transmission belt 11 is located on one side of the fixed base 2. The moving block 13 is threaded onto the outer wall of the lead screw 14, and the side wall of the moving block 13 is slidably connected to the inside of the hollow sliding plate 6. The two moving blocks 13 are respectively located in the guide rail grooves opened inside the corresponding hollow sliding plates 6. Clamping cylinders 5 are provided inside the two moving blocks 13. Clamping claws 12 are fixedly connected to the opposite ends of the two clamping cylinders 5. A drive motor 7 is fixedly connected to the side of the fixed base 2 near the transmission belt 11. The drive end of the drive motor 7 is connected to one end of one of the lead screws 14 through a coupling.
[0044] During the pile driving process, a lifting cylinder 10 is installed. Under the action of the lifting cylinder 10, the guide pipe 8 slowly descends until the rubber ring 16 contacts the ground, so that the guide pipe 8 wraps the driving hole to prevent stones and other factors from entering the driving hole during pile driving and scratching the anti-corrosion layer on the pile surface.
[0045] Working Principle: First, the worker moves the foundation pile to the required position using a guide device. Then, the lifting cylinder 10 is activated. Under the action of the lifting cylinder 10, the guide tube 8 slowly descends until the rubber ring 16 contacts the ground, allowing the guide tube 8 to enclose the sinking hole and prevent stones or other factors from entering the sinking hole and scratching the anti-corrosion layer on the foundation pile surface during foundation pile sinking. Then, the drive motor 7 is activated, causing the two lead screws 14 to rotate under the action of the transmission belt 11. The moving block 13 moves towards the end away from the fixed seat 2 under the action of the lead screws 14, carrying the clamping claws 12. When it reaches the required position, the clamping cylinder 5 is activated to widen the distance between the two clamping claws 12. Then, the worker operates the crane 1 to transport the foundation pile between the two clamping claws 12. Then, the clamping cylinder 5 is activated again to tightly clamp the two clamping claws 12 against the outer wall of the foundation pile. Finally, the drive motor 7 is activated. The pile is moved to the upper side of the guide tube 8 under the gripping claw 12. Then, by adjusting the gripping cylinder 5, the pile is lowered into the guide tube 8. Inside the guide tube 8, the outer wall of the pile is in direct contact with the roller 1706 under the action of the buffer spring 1703 and the roller 1706, which will not damage the anti-corrosion coating of the outer wall. The rotation of the roller 1706 drives the two buffer wheels 1707 to continuously move the ratchet on the ratchet plate 1705 in contact with it. Due to the friction between the ratchet plate 1705 and the buffer wheel 1707, the rotation of the roller 1706 is made with a certain resistance, which slows down the speed of the pile when it falls and prevents the pile head from colliding and being damaged due to excessive speed. When the pile is lowered to the required position, the lifting cylinder 10 is controlled to lift the guide tube 8 and move the machine to carry out the subsequent pile lowering work.
[0046] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
