Description

Technical Field

[0001] The utility model relates to a pile driving guide frame. Background Art

[0002] In construction projects, especially in large-scale infrastructure such as marine engineering, bridge construction, high-rise buildings, and port terminals, pile sinking is a crucial step. The quality of pile sinking is directly related to the safety and stability of the entire project.

[0003] Traditional pile driving operations often need to be carried out separately at each pile driving point, which makes it difficult to effectively use the piles that have been driven as a reference or auxiliary. As a result, the relative position relationship between adjacent piles is difficult to accurately control, which in turn affects the stability and bearing capacity of the entire foundation.

[0004] Therefore, a pile driving guide frame is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to overcome the existing defects and provide a pile driving guide frame, which improves the precision and accuracy of pile driving, greatly shortens the operation cycle, and improves construction efficiency.

[0006] The technical solution to achieve the above-mentioned purpose is: a pile driving guide frame, including a frame-shaped base frame, a truss group is connected to the middle and rear ends of the frame-shaped base frame, and the truss group is rotatably connected to the crossbeam; the truss group in the middle of the frame-shaped base frame is connected to a fixed rod, and the fixed rod is connected to a mobile drive assembly; the front end of the frame base frame is connected to a roller.

[0007] Preferably, the frame-shaped chassis includes two chassis rods, the front ends of the two chassis rods are connected by a connecting bottom rod, and a limiting groove is formed between the two chassis rods; the roller is arranged on the connecting bottom rod.

[0008] Preferably, the mobile drive assembly includes a hydraulic cylinder, the output end of the hydraulic cylinder is rotatably connected to the fixed rod through a hinge seat, the tail end of the hydraulic cylinder is connected to a fixed block, a slidingly connected pin passes through the fixed block, the lower end of the pin is connected to the pin block, and the upper end is connected to the handle.

[0009] Preferably, a flared plate is connected to each of the front end opposite surfaces of the two chassis rods.

[0010] Preferably, there are two rollers, each of which is connected to the connecting bottom rod via a fixing frame.

[0011] Preferably, the crossbeam is made of high-strength alloy steel, and its surface is covered with a wear-resistant coating.

[0012] Preferably, a lifting ring is connected to the frame-shaped base frame.

[0013] The beneficial effects of the present invention are as follows: the pile driving guide frame, by arranging limit grooves on the frame-shaped base frame, can accurately define the position and direction of the pile column to be sunk during the pile driving process, effectively reducing the pile driving deviation caused by complex geological conditions, thereby improving the precision and accuracy of pile driving. At the same time, the pile columns that have been sunk are used as a reference or auxiliary, so that the relative position relationship between adjacent pile columns is easier to accurately control, thereby enhancing the stability and bearing capacity of the entire foundation structure. The pile driving guide frame is equipped with a driving assembly, which can drive the structural frame to flexibly move forward or backward on the pile columns that have been sunk, and there is no need to perform separate operation preparations at each pile driving point, which greatly shortens the operation cycle and improves construction efficiency.

[0018] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center," "up," "down," "left," "right," "vertical," "horizontal," "inside," "outside," and the like, indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be construed as limiting the present invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figure 1-3As shown, a pile driving guide frame includes a frame base 1, a truss group 2 is connected to the middle and rear end of the frame base 1, and the truss group 2 is rotatably connected to the crossbeam 6; the truss group 2 in the middle of the frame base 1 is connected to the fixed rod 14, and the fixed rod 14 is connected to the mobile drive assembly; the front end of the frame base 1 is connected to the roller 3.

[0021] Specifically, the frame-shaped base frame 1 includes two base bars 15, the front ends of which are connected by a connecting base bar 16. A retaining slot 4 is formed between the two base bars 15. The width of the retaining slot 4 matches the width of the pile 12, ensuring that when the pile 12 is placed within the retaining slot 4, both sides of the pile 12 are effectively supported and restrained. Two rollers 3 are mounted on the connecting base bar 16. Each roller 3 is connected to the connecting base bar 16 via a fixing bracket 18. A gap 13 is formed between two adjacent piles 12 that have been driven into the ground.

[0022] Specifically, by setting a limit groove 4 on the inner side of the frame-shaped base frame 1, the limit groove 4 can accurately define the position and direction of the pile column 12 to be sunk during the pile sinking process, effectively reducing the pile sinking deviation caused by complex geological conditions, thereby improving the precision and accuracy of pile sinking. At the same time, using the pile columns 12 that have been sunk as a reference or auxiliary, the relative position relationship between adjacent pile columns 12 is easier to accurately control, thereby enhancing the stability and bearing capacity of the entire foundation structure. The pile sinking guide frame is equipped with a driving assembly, which can drive the structural frame to flexibly move forward or backward on the pile columns 12 that have been sunk, without the need for separate operation preparation at each pile sinking point, which greatly shortens the operation cycle and improves construction efficiency.

[0023] Specifically, a retaining groove 4 is formed on the inner side of the frame-shaped base frame 1. A cylindrical crossbeam 6 is fixedly connected to the top of the truss assembly, and the crossbeam 6 can slideably contact the top of the already driven pile column 12. The frame-shaped base frame 1 and the spaced and fixed truss assembly together constitute the main framework of the structural frame. This not only improves the rigidity and stability of the overall structure, but also effectively resists the various forces and moments generated during the pile driving process, ensuring the safe progress of the pile driving operation. The cylindrical crossbeam 6 is arranged so that it can slideably contact the top of the already driven pile column 12.

[0024] Specifically, the mobile drive assembly includes a hydraulic cylinder 7, the output end of the hydraulic cylinder 7 is rotatably connected to the fixed rod 14 through a hinge seat 17, the tail end of the hydraulic cylinder 7 is connected to the fixed block 8, and the fixed block 8 is penetrated by a slidingly connected pin 9, the lower end of the pin 9 is connected to the pin block 11, and the upper end is connected to the handle 10.

[0025] Specifically, the hydraulic cylinder 7 is connected to a hydraulic station. When working, after the hydraulic cylinder 7 releases pressure, its cylinder body is pushed forward, causing the piston rod of the hydraulic cylinder 7 to contract and inserting the pin 9 into the gap 13. At this time, the pin 9 serves as a support point, and the piston rod of the hydraulic cylinder 7 extends, thereby driving the frame chassis 1 to move forward. When the piston rod contracts again under the driving force of the hydraulic pump station, it drives the frame chassis 1 to move backward, thereby making the pile column 12 to be sunk close to the pile column 12 that has been sunk.

[0026] Specifically, a longitudinal slot is provided within the fixed block 8, and a latch 9 is slidably connected to the longitudinal slot. A handle 10 is fixedly connected to one end of the latch 9, and a pin block 11 is fixedly connected to the other end. The pin block 11 is adapted to fit within the gap 13 between two already sunk piles 12. The latch 9 is slidably connected to the fixed block 8 via the longitudinal slot, allowing construction workers to easily control the movement of the latch 9 using the handle 10, without the need for complex tools or tedious adjustments, thereby improving construction efficiency. The latch 9 is securely inserted into the gap 13 between the already sunk piles 12 via the pin block 11, providing a stable support point for the pile driving guide frame. This not only enhances the stability of the pile driving guide frame during the pile driving process, but also helps prevent it from shaking or deflecting due to external forces.

[0027] Specifically, a flared plate 5 is connected to the front facing surfaces of the two chassis rods 15. The flared plate 5 provides an eight-shaped flared opening at the top of the limiting groove 4. The eight-shaped flared opening guides the component pile 12 to be inserted into the limiting groove 4 more easily and accurately.

[0028] Specifically, the crossbeam 6 is made of high-strength alloy steel and its surface is covered with a wear-resistant coating, which ensures that the crossbeam 6 has good wear resistance when sliding relative to the pile 12 .

[0029] Specifically, a lifting ring is connected to the frame-shaped base frame 1. The lifting ring provides a convenient connection point for overall lifting, making the installation, disassembly and movement of the pile driving guide frame between different working points easier and more efficient.

[0030] When in use, at the target position, first use the traditional method to sink several piles 12 as a reference to ensure that the position, depth and verticality of these piles 12 meet the design requirements; hoist the pile sinking guide frame onto the pile 12 that has been sunk, and use the hoisting ring and lifting equipment to firmly place the guide frame in the predetermined position; the mobile drive component is started, and the drive structure frame moves forward a certain distance along the surface of the pile 12 that has been sunk. The determination of this distance requires ensuring that there is enough space between the limit groove 4 and the pile 12 that has been sunk. The space should be larger than the width of a pile 12 to be sunk, so that the pile to be sunk can be hoisted and placed smoothly; after confirming that the position of the guide frame is correct, use the lifting equipment to hoist the pile 12 to be sunk to the limit groove In the reserved space between the groove 4 and the pile column 12 that has been sunk, at this time, it should be ensured that the position and direction of the pile to be sunk are accurate so that the subsequent pile sinking operation can proceed smoothly; the frame base 1 moves backward through the mobile driving component, so that the pile column 12 to be sunk in the limit groove 4 is tightly attached to the pile column 12 that has been sunk; after the pile column 12 to be sunk is tightly attached to the pile column 12 that has been sunk, the pile sinking operation is started, and the pile sinking equipment pushes the pile column 12 to be sunk to gradually sink to a predetermined depth. During the entire pile sinking process, the roller 3 plays a guiding role; after the pile sinking is completed, check the pile sinking quality and the relative position relationship between adjacent pile columns 12. If the construction requirements are met, continue to repeat the above steps to carry out the pile sinking operation of the next pile column 12.

[0031] The pile driving guide frame is provided with a limit groove 4 on the frame base 1. The limit groove 4 can accurately define the position and direction of the pile column to be driven during the pile driving process, effectively reducing the pile driving deviation caused by complex geological conditions, thereby improving the precision and accuracy of pile driving. At the same time, the pile column that has been driven is used as a reference or auxiliary, so that the relative position relationship between adjacent pile columns is easier to accurately control, thereby enhancing the stability and bearing capacity of the entire foundation structure. The pile driving guide frame is equipped with a driving component, which can drive the structural frame to flexibly move forward or backward on the pile column that has been driven. There is no need to perform separate operation preparations at each pile driving point, which greatly shortens the operation cycle and improves construction efficiency.
