Description
Technical Field
[0001] This utility model relates to the technical field of supporting equipment for pile foundation construction, and in particular to a high-efficiency positioning and guiding structure for pile foundation construction devices. Background Technology
[0002] As a fundamental part of building construction, the quality of pile foundation engineering directly affects the stability and safety of the entire building. During the pile foundation construction process, it is necessary to use construction equipment to accurately position and guide the piles to ensure that the piles can be driven vertically into the ground and always remain in the preset design position.
[0003] Currently, existing pile foundation construction equipment mostly uses traditional rigid clamps or single bolt fastening methods to fix piles. This method lacks sufficient structural stability and adjustment flexibility when facing the complex stress environment of the construction site, and it is difficult to form a stable triangular support system. This causes the pile foundation to tilt or shift its position when subjected to lateral external forces, which seriously affects the construction accuracy and work efficiency. In addition, the pile foundation construction process is accompanied by continuous and severe mechanical vibration. The existing construction equipment base and fixing components lack a special vibration damping and buffer design, which causes the huge impact energy generated during construction to be directly transmitted to the equipment base and various connection parts. Long-term severe vibration causes stress concentration at the connection welds of the equipment, which in turn leads to weld cracking or even structural fracture. This not only significantly shortens the service life of the equipment, but also brings serious safety hazards to the construction site.
[0004] Therefore, this utility model proposes an efficient positioning and guiding structure for pile foundation construction devices to address the shortcomings of existing technologies. Utility Model Content

[0006] This utility model provides an efficient positioning and guiding structure for a pile foundation construction device, including: a base, a fixed seat; and a fixing mechanism for positioning and guiding the pile foundation, wherein the fixing mechanism includes a clamping plate, a connecting rod, a fixing rod, a fixing block, and bolts.

[0017] This utility model has the following beneficial effects:
[0018] 1. This utility model solves the problems of unstable pile foundation fixing, inaccurate positioning, and easy tilting or loosening during pile foundation construction by setting a linkage mechanism consisting of a clamping plate, a connecting rod, and a fixing rod around the fixed seat on the top wall of the base. The linkage mechanism forms a stable triangular support structure by pulling the clamping plate and locking it with bolts.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.
[0029] Example:
[0030] Please refer to Figures 1 to 6 This utility model provides an efficient positioning and guiding structure for a pile foundation construction device. This utility model aims to solve the problems of inaccurate pile foundation positioning, easy tilting and loosening, and the inability to effectively absorb vibration energy generated during construction, which leads to fatigue damage to the device structure.
[0031] Please refer to Figure 1 and Figure 2 The high-efficiency positioning and guiding structure of the pile foundation construction device includes a base 1 and a fixed seat 206 fixedly connected to the middle of the top wall of the base 1. The base 1 serves as the installation support foundation for the entire device, bearing the overall weight and vibration load during construction. The inner wall of the fixed seat 206 is cylindrical, used to accommodate the pile foundation to be constructed and provide foundation limit during construction. The top wall of the base 1 is provided with a fixing mechanism 2 for positioning and guiding the pile foundation. The top wall of the base 1 is also provided with a vibration damping mechanism 3 for absorbing the vibration energy generated during the pile foundation construction. The fixing mechanism 2 is located around the fixed seat 206 and is connected to the pile foundation. The vibration damping mechanism 3 is located on the left and right sides of the top wall of the base 1 and works in conjunction with the fixed seat 206.
[0032] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The fixing mechanism 2 includes a clamping plate 201, a connecting rod 202, a fixing rod 203, a fixing block 204, and bolts 205. Fixing blocks 204 are fixedly connected to the upper middle parts of both sides of the outer wall of the fixing seat 206. A fixing rod 203 is rotatably connected to the inner wall of the fixing block 204. A connecting rod 202 is rotatably connected to the outer wall of the fixing rod 203 away from the fixing block 204. A clamping plate 201 is rotatably connected to the inner wall of the connecting rod 202. The clamping plate 201 is constructed to conform to the shape of the outer wall of the pile foundation and slides against it. Multiple bolts 205 are threaded at equal intervals on the inner wall of the clamping plate 201. The threaded connection of these bolts 205 allows the ends of the bolts 205 to extend out of the inner wall of the clamping plate 201 to press against the pile foundation, or to retract into the inner wall of the clamping plate 201 to release the pile foundation. The fixing block 204 and the fixing rod 205... The rotational connection between the three rods allows the fixed rod 203 to rotate around the pivot 304 of the fixed block 204, thereby causing the connecting rod 202 to change position. The rotational connection between the connecting rod 202 and the clamping plate 201 is achieved through a pin, allowing the clamping plate 201 to swing around the connection point of the connecting rod 202 as the axis. The clamping plate 201, the connecting rod 202, and the fixed rod 203 together form a stable triangular support structure. By pulling the clamping plate 201, it slides upward along the outer wall of the pile foundation. While the clamping plate 201 moves, it pulls the connecting rod 202, and the connecting rod 202 then pulls the fixed rod 203, thereby forming a stable and adjustable triangular structure for efficient positioning and guidance of the pile foundation. Tightening the bolt 205 securely locks the clamping plate 201 to the pile foundation, preventing the pile foundation from tilting or loosening during construction.
[0033] As a preferred embodiment, in order to absorb the vibration energy generated during pile foundation construction to reduce the vibration amplitude and frequency of the structure and prevent weld cracking, please refer to... Figure 5 and Figure 6 The top wall of the base 1 is provided with a vibration damping mechanism 3, which includes a fixed plate 301, a fixed frame 302, a limiting plate 303, a rotating shaft 304, a damper 305, and a connecting plate 306. Fixed plates 301 are fixedly connected to both the left and right sides of the top wall of the base 1. A fixed frame 302 is fixedly connected to the upper middle part of the outer wall of the fixed plate 301. A rotating shaft 304 is rotatably connected to the inner wall of the fixed frame 302. A limiting plate 303 is fixedly connected to one end of the rotating shaft 304 near the fixed seat 206.
[0034] In a preferred embodiment, to address the power transmission issue between the fixed base 206 and the vibration damping mechanism 3 and to avoid damage caused by rigid collisions, one side of the limiting plate 303 maintains elastic contact with the outer wall of the fixed base 206. Specifically, an elastic washer or spring is provided between the limiting plate 303 and the outer wall of the fixed base 206 to achieve elastic contact and engagement, allowing the fixed base 206 to flexibly push the limiting plate 303 when it vibrates.
[0035] In a preferred embodiment, in order to amplify the damping effect and dissipate energy efficiently by utilizing the lever principle, a connecting plate 306 is fixedly connected to the end of the rotating shaft 304 away from the fixed base 206. A damper 305 is rotatably connected to the outer wall of the fixed plate 301. The top of the damper 305 is rotatably connected to the end of the connecting plate 306. The kinetic energy is converted into heat energy and dissipated by the swinging of the connecting plate 306 to compress or stretch the damper 305.
[0036] Working principle: When fixing the pile foundation, the pile foundation is first installed into the inner space of the fixing seat 206. The clamping plate 201 is pulled upward to slide upward along the outer wall of the pile foundation. During the upward movement of the clamping plate 201, the connecting rod 202 is driven to move. The connecting rod 202 pulls the fixing rod 203 to rotate around the fixing block 204. When it moves to a suitable height, a stable triangular support structure is formed between the fixing rod 203 and the connecting rod 202 and the side of the pile foundation. Then, the multiple bolts 205 on the clamping plate 201 are tightened so that the bolts 205 are pressed against the surface of the pile foundation, and the clamping plate 201 and the pile foundation are firmly locked to prevent the pile foundation from tilting or loosening during construction.
[0037] During the pile foundation construction process, severe vibrations occur. When the fixed seat 206 experiences slight displacement or swaying due to vibration, the outer wall of the fixed seat 206 presses against or collides with the limiting plate 303, which is in elastic contact with it. The limiting plate 303 swings under force and drives the connecting plate 306 on the other side to rotate and swing through the rotating shaft 304. The end of the connecting plate 306 then presses or pulls the damper 305 downward. At this time, the damper 305 performs telescopic movement. The damping characteristics inside the damper 305 are used to absorb energy and convert the mechanical impact kinetic energy into heat energy for dissipation. The vibration reduction mechanism 3 effectively reduces the amplitude and frequency of structural vibration and prevents weld cracking and fatigue damage of the device.
