Abstract
Description
Technical Field
[0001] This utility model relates to the field of piling, specifically to a guide for driving H-type precast piles. Background Technology
[0002] Using precast piles for construction can significantly improve construction efficiency and reduce costs. Ensuring precise driving of precast piles is the core of precast pile construction, a crucial factor in guaranteeing construction quality and shortening the construction cycle. Currently, in precast pile driving, tilting and deviation are common occurrences, necessitating the extraction and re-driving of the driven pile. While guide devices can improve driving accuracy, they are not suitable for all precast pile driving requirements, especially for precast piles with unique cross-sectional shapes. Utility Model Content
[0003] The purpose of this invention is to provide a guide for driving H-type precast piles, which can improve the driving accuracy, quality and efficiency of H-type precast piles.
[0004] To achieve the above objectives, the present invention adopts the following scheme.
[0005] A guide for driving H-type precast piles is characterized by comprising a first pile clamping guide arm and a second pile clamping guide arm rotatably mounted on a pile driver. The first and second pile clamping guide arms are arranged horizontally opposite each other. The front ends of the first and second pile clamping guide arms are respectively provided with a first pile clamping mounting part and a second pile clamping mounting part. The first pile clamping guide arm and the first pile clamping mounting part are arranged in an L-shape, and the second pile clamping guide arm and the second pile clamping mounting part are also arranged in an L-shape.

The axial directions of the first pile clamping guide wheel, the second pile clamping guide wheel, the first pile clamping guide arm, and the second pile clamping guide arm are all consistent with direction F1, which is the length direction of the first pile clamping guide arm. The first and second pile clamping guide arms are respectively connected to a rotation adjustment component for adjusting their rotation.
[0006] A further solution is as follows: The pile driver is equipped with a first bushing and a second bushing, and the middle parts of the first pile clamping guide arm and the second pile clamping guide arm are rotatably installed in the first bushing and the second bushing, respectively. The first pile clamping installation part and the second pile clamping installation part are respectively located at one end of the first pile clamping guide arm and the second pile clamping guide arm. The rotation adjustment component is connected to the other end of the first pile clamping guide arm and the second pile clamping guide arm.
[0007] The first and second pile clamping installation sections are also equipped with a first anti-deviation component and a second anti-deviation component to prevent the precast piles from deviating.
[0008] The first anti-deviation component and the second anti-deviation component have the same structure. The first anti-deviation component includes A1 anti-deviation roller and A2 anti-deviation roller, which are rotatably installed. The plane where the center lines of A1 anti-deviation roller and A2 anti-deviation roller are located is called plane A. Plane A is arranged parallel to directions F1 and F2. Direction F2 is the length direction of the first clamping pile mounting part. Surfaces A1 and A2 are arranged at an angle and the angle points to the side closer to the guide arm of the first clamping pile. Surface A1 is the outer tangent of anti-deviation roller A1 and is arranged perpendicular to plane A. Surface A2 is the outer tangent of anti-deviation roller A2 and is arranged perpendicular to plane A.
[0009] The A1 and A2 anti-deviation rollers are cylindrical rollers, and their center lines are arranged at an angle.

Detailed Implementation
[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0022] As used herein, the terms “parallel,” “perpendicular,” and the like are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors.
[0023] For some engineering projects, the height of the precast pile head above the ground after piling is required to be relatively small. This necessitates that the clamping device 04 and the pile hammer 03 move to the underside of the guide, a feature that traditional guides cannot reliably achieve. The solution adopted in this invention is as follows... Figures 1-4As shown, a guide for driving an H-type precast pile 30 includes a first guide unit 10 and a second guide unit 20. The first guide unit 10 and the second guide unit 20 each include a first pile clamping guide arm 11 and a second pile clamping guide arm rotatably mounted on a pile driver 01. The first pile clamping guide arm 11 and the second pile clamping guide arm are arranged horizontally opposite each other. The front ends of the first pile clamping guide arm 11 and the second pile clamping guide arm are respectively provided with a first pile clamping mounting part 12 and a second pile clamping mounting part. The first pile clamping guide arm 11 and the first pile clamping mounting part 12 form an L-shape. The second pile clamping guide arm and the second pile clamping installation part are arranged in an L-shape. The front ends of the first pile clamping installation part 12 and the second pile clamping installation part are respectively equipped with a rotatably mounted first pile clamping guide wheel 13 and a second pile clamping guide wheel. The axial directions of the first pile clamping guide wheel 13, the second pile clamping guide wheel, the first pile clamping guide arm 11, and the second pile clamping guide arm are all consistent with direction F1, which is the length direction of the first pile clamping guide arm 11. The first pile clamping guide arm 11 and the second pile clamping guide arm are respectively connected to a rotation adjustment assembly for adjusting their rotation. By rotating the first pile clamping guide arm 11 and the second pile clamping guide arm, the first pile clamping installation part 12 and the second pile clamping installation part can be moved closer or further apart, ensuring reliable clamping when the precast pile needs to be clamped and guided, and reliable avoidance when it is necessary to avoid the passage of the clamping device 04 and the pile hammer 03, thus improving the adaptability range of pile driving. The first pile clamping guide wheel 13 and the second pile clamping guide wheel are used to clamp and guide the first pile surface 32 on the H-shaped precast pile 30.
[0024] like Figure 2 , 3As shown, a further embodiment is as follows: A first bushing 16 and a second bushing are respectively installed on the pile driver 01. The middle portions of the first pile clamping guide arm 11 and the second pile clamping guide arm are rotatably installed within the first bushing 16 and the second bushing, respectively. The first pile clamping mounting part 12 and the second pile clamping mounting part are respectively located at one end of the first pile clamping guide arm 11 and the second pile clamping guide arm. A rotation adjustment component is connected to the other end of the first pile clamping guide arm 11 and the second pile clamping guide arm. The first pile clamping mounting part 12 and the second pile clamping mounting part are also respectively equipped with a first anti-deviation component and a second anti-deviation component to prevent the precast pile from deviating. The first and second anti-deviation components have the same structure. The first anti-deviation component includes rotatably mounted anti-deviation rollers A1 14 and A2 15. The plane containing the center lines of anti-deviation rollers A1 14 and A2 15 is denoted as plane A. Plane A is parallel to directions F1 and F2, with direction F2 being the length direction of the first pile clamping mounting part 12. Surfaces A1 and A2 are arranged at an angle, with the angle pointing towards the side closest to the first pile clamping guide arm 11. Surface A1 is the outer tangent of anti-deviation roller 14 and is perpendicular to plane A, and surface A2 is the outer tangent of anti-deviation roller 15 and is perpendicular to plane A. By having anti-deviation rollers A1 14 and A2 15 roll and abut against the second pile surface 31 on the H-shaped precast pile 30, tilting or deviation of the H-shaped precast pile 30 during pile driving is prevented, thus improving the pile driving quality. The partial roller surfaces of anti-deviation rollers A1 (14) and A2 (15) are located outside the first clamping pile mounting portion 12. Specifically, there are two implementation methods: First, anti-deviation rollers A1 (14) and A2 (15) are cylindrical rollers, with their center lines arranged at an angle. Second, anti-deviation rollers A1 (14) and A2 (15) are conical rollers, with their center lines arranged parallel. The appropriate method can be selected based on specific needs to improve the effectiveness of the application.
[0025] A more preferred embodiment is that the first and second pile clamping mounting parts 12 and 12 are triangular or trapezoidal mounting bases, with their length directions aligned with the height of the triangle or trapezoid. The rotation adjustment assembly includes a first and a second hydraulic cylinder. The other ends of the first and second pile clamping guide arms 11 and 12 are respectively equipped with a first crank 17 and a second crank. The piston rods of the first and second hydraulic cylinders are hinged to the first and second cranks, respectively. An assembly rod 18 is mounted on the first bushing 16, and a positioning device 19 is mounted on the assembly rod 18. The length directions of the first and second hydraulic cylinders are perpendicular to direction F. The cylinder bodies of the first and second hydraulic cylinders are hinged to the pile driver 01, thereby adjusting the rotation of the first and second pile clamping guide arms 11 and 12 by adjusting the extension and retraction of the piston rods. More specifically, the guide is installed on the drop hammer pile driver 01, and the pile driver 01 is equipped with a vertically arranged pile frame 02. The first bushing 16 and the second bushing are both fixedly installed on the pile frame 02.
[0026] In summary, the technical solution provided by this utility model can reliably guide the H-type precast pile 30, thereby improving the pile driving quality, pile driving efficiency, and applicable scope of the H-type precast pile 30.
[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional methods in the field.
