Description

Technical Field

[0001] This utility model relates to the field of piling equipment technology, specifically to an automatic piling correction device. Background Technology

[0002] Driven piles (also known as pile driving) are a widely used construction technique in foundation engineering. They are precast piles (such as reinforced concrete piles and prestressed concrete piles) are driven into the soil layer by the impact energy of a pile hammer. The pile body and the surrounding soil are squeezed and compacted to form a foundation structure with high bearing capacity and stability. During the pile driving process, the control of the verticality deviation of the pile body is the key to ensuring the quality of the pile.

[0003] Traditional pile driving correction techniques mainly rely on manual visual inspection and experience-based judgment, correcting deviations by adjusting the pile frame guide structure or the direction of the pile hammer force. However, manual observation is easily affected by ambient light, distance, and the operator's subjective factors, making it difficult to achieve high-precision correction. During the pile sinking process, the deviation accumulates rapidly, and the response of manual intervention is delayed, which can easily lead to pile tilting or even scrapping. Therefore, we propose an automatic pile driving correction device to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] An automatic pile driving correction device includes:

[0006] A rectangular base, wherein guide rods are fixed at the four corners of the top of the rectangular base, and a connecting plate is fixed between the tops of the guide rods on the same side. A rectangular groove is opened in the middle of the top of the rectangular base, and a channel is constructed in the middle of the rectangular groove.

[0007] A movable plate is slidably sleeved between the guide rods. An installation column is fixedly embedded in the middle of the movable plate. An installation groove is opened at the bottom of the installation column, and the upper end of the precast pile is embedded in the installation groove.

[0008] A trapezoidal seat is embedded inside the rectangular groove, and a guide tube is fixedly embedded in the middle of the trapezoidal seat, through which the precast pile slides.

[0009] Furthermore, the mounting groove is conical in shape, and its diameter gradually decreases from its port to its interior.

[0010] Furthermore, a pull rope is connected to the inner top wall of the mounting groove, and a sponge ball is provided at the free end of the pull rope.

[0011] Furthermore, the two inclined surfaces of the trapezoidal seat are symmetrically constructed with U-shaped grooves, and the two sides of the rectangular groove are threaded with limiting rods extending into the U-shaped grooves.

[0012] Furthermore, the rectangular seat has a U-shaped notch at the center of its front and rear sides that communicates with the rectangular groove, and the trapezoidal seat has a positioning rod fixed on its front and rear sides, the positioning rod being slidably embedded inside the U-shaped notch.

[0013] Furthermore, a cross groove is provided in the middle of the top of the mounting post.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] This application provides an automatic pile driving correction device, mainly to solve the problem that existing technologies rely primarily on manual visual inspection and experience-based judgment, correcting deviations by adjusting the pile frame guide structure or the direction of the pile hammer force. However, manual visual inspection is easily affected by ambient light, distance, and the operator's subjective factors, making it difficult to achieve high-precision correction. Furthermore, the rapid accumulation of deviations during pile sinking and the delayed response of manual intervention can easily lead to pile tilting or even failure. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-5 Please provide a detailed explanation:

[0024] An automatic pile driving correction device includes:

[0025] A rectangular base 1 is provided with guide rods 2 fixed at the four corners of the top of the rectangular base 1. A connecting plate 3 is fixed between the tops of the guide rods 2 on the same side. A rectangular groove 101 is provided in the middle of the top of the rectangular base 1. A channel 102 is constructed in the middle of the rectangular groove 101.

[0026] The movable plate 4 is slidably sleeved between the guide rods 2. The middle part of the movable plate 4 is fixedly embedded with the mounting column 5. The bottom of the mounting column 5 is provided with the mounting groove 501. The upper end of the precast pile is embedded in the mounting groove 501.

[0027] A trapezoidal seat 6 is embedded inside a rectangular groove 101. A guide tube 7 is fixedly embedded in the middle of the trapezoidal seat 6. The precast pile slides through the guide tube 7. The two inclined surfaces of the trapezoidal seat 6 are symmetrically constructed with U-shaped grooves 601. Limiting rods 10 extending into the U-shaped grooves 601 are threadedly connected to both sides of the rectangular groove 101.

[0028] Workflow Description

[0029] The first step is to embed the trapezoidal seat 6 into the rectangular groove 101 of the rectangular seat 1, and rotate the threaded limiting rods 10 on both sides to embed them into the U-shaped groove 601 on the inclined surface of the trapezoidal seat 6, thus fixing the trapezoidal seat 6. (It should be noted that the guide tube 7 inside the trapezoidal seat 6 is a matching set with the precast pile and can be customized according to different specifications of precast piles.)

[0030] The second step is to insert the bottom of the precast pile into the guide tube 7 in the middle of the trapezoidal seat 6, and embed the upper end into the installation groove 501 at the bottom of the movable plate 4, with the auxiliary pile body in the center.

[0031] The third step involves using a heavy hammer to strike the cross groove 502 at the top of the installation column 5, driving the precast pile to sink. The movable plate 4 slides down along the guide rod 2 at the top of the rectangular base 1, and the installation column 5 moves synchronously with the pile body. The guide tube 7 constrains the bottom of the pile body, and the installation groove 501 limits the top of the pile. Double correction ensures verticality until the pile sinking is completed.

[0032] This automatic pile driving correction device is designed with a combination of mounting column 5 and guide pipe 7. The guide pipe 7 constrains the bottom of the pile body, and the mounting groove 501 limits the top of the pile. It does not require dedicated personnel to monitor the correction process. Semi-automatic construction can be achieved by simply presetting the parameters of the limit rod 10, which saves labor costs. The automatic correction response speed is much faster than manual intervention, reducing downtime and adjustment time. It is especially suitable for rapid pile driving operations.

[0033] like Figure 3 As shown, in some embodiments, the mounting groove 501 is conical, with its diameter gradually decreasing from its port to the inside. More specifically, the sidewalls of the mounting groove 501 are conical surfaces, gradually narrowing from the port (larger opening) to the bottom (smaller opening). This design allows the precast pile to be forced to move closer to the axis due to the guiding effect of the conical surface when inserted, thereby achieving automatic centering.

[0034] like Figure 3 As shown, in some embodiments, the inner top wall of the mounting groove 501 is connected to a pull rope 8, and the free end of the pull rope 8 is provided with a sponge ball 9. More specifically, when the top of the precast pile is embedded in the conical mounting groove 501, the pile body is initially centered due to the constraint of the conical surface. The sponge ball 9, as a flexible medium, can buffer the rigid collision between the pile top and the mounting groove 501, and avoid local stress concentration in the pile body leading to cracks.

[0035] like Figure 4 As shown, in some embodiments, the rectangular base 1 has a U-shaped notch 103 at the middle of its front and rear sides that communicates with the rectangular groove 101. The trapezoidal base 6 has a positioning rod 11 fixed on its front and rear sides. The positioning rod 11 is slidably embedded in the U-shaped notch 103. More specifically, when the trapezoidal base 6 is embedded in the rectangular groove 101, its positioning rod 11 slides along the U-shaped notch 103. At this time, the lateral displacement of the trapezoidal base 6 is restricted. The symmetrical design of the U-shaped notch 103 forces the trapezoidal base 6 to be unable to shift laterally. The sliding cooperation between the positioning rod 11 and the U-shaped notch 103 forms a "track constraint" to ensure that the guide tube 7 of the trapezoidal base 6 is always coaxial with the mounting column 5.

[0036] like Figure 4 As shown, in some embodiments, a cross groove 502 is provided in the middle of the top of the mounting column 5. More specifically, manual pile driving relies on manual aiming, which is prone to deviation due to visual errors or unstable operation, resulting in lateral force that causes the pile to tilt. The cross groove 502 can assist the staff to hammer towards the center area, reduce the operation threshold, and improve the operation accuracy.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
