Abstract
Description
Technical Field
[0001] This application relates to the field of engineering surveying technology, and in particular to a quick-installation benchmark pile. Background Technology
[0002] Benchmark piles are permanent markers used in engineering construction to provide precise reference points. They are typically made of sturdy materials such as concrete and steel, and have precise measurement points at their top. Their core function is to serve as a reference for the entire engineering surveying, construction layout, and deformation monitoring process. They provide a unified and stable measurement basis for the planar position, elevation, and dimensions of buildings and structures, ensuring that all parts of the project meet design standards during construction and operation. They also provide a continuous benchmark reference for subsequent maintenance, renovation, and expansion work.
[0003] The working principle of a benchmark pile is based on its inherent stability and accuracy. In the early stages of construction, professional surveying techniques such as total stations and levels are used to determine its precise coordinates in a specific coordinate system (plane or elevation), and these coordinates are then used as a fixed reference value. During subsequent construction or monitoring, surveying instruments use the benchmark pile's coordinates as a starting point, comparing the relative positions of the measured point and the benchmark pile (such as distance, angle, and elevation difference) to calculate the precise data for the measured point. This allows for accurate control and monitoring of parameters such as the structural position, elevation, and deformation, ensuring that all construction stages and monitoring data are always based on a unified benchmark, thus guaranteeing project accuracy and consistency.
[0004] Currently, some existing benchmark piles suffer from inconvenient U-shaped component adjustment during use. When adjusting the angle, height, or position according to actual working conditions, the operation is cumbersome, requiring various specialized tools, and precise positioning is difficult to achieve during adjustment, easily leading to over- or under-adjustment. Furthermore, after long-term use, the connection points of the U-shaped components become stuck due to wear and corrosion, further exacerbating the adjustment difficulty. This not only affects the efficiency of the benchmark pile but also reduces the accuracy of measurement data due to improper adjustment, causing inconvenience to subsequent engineering surveying and construction work. Therefore, a quick-installation benchmark pile is proposed to solve these problems. Utility Model Content

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.
[0032] Example: A benchmark pile that can be installed quickly, referring to... Figures 1 to 3 The system includes a drill rod 1, to which an adjusting mechanism 2 is fixedly connected. Through this fixed connection, the adjusting mechanism 2 can move and be fixed in position relative to the drill rod 1, ensuring its stability during operation. A U-shaped component 3 is fixedly connected to the rear of the adjusting mechanism 2. The U-shaped component 3 serves as a connection carrier between the reference pile and external equipment or components. Through this fixed connection, it can move synchronously with changes in the position of the adjusting mechanism 2 on the drill rod 1. A connecting mechanism 4 is fixedly connected internally to the rear of the adjusting mechanism 2. When the adjusting mechanism 2 moves the U-shaped component 3, the connecting mechanism 4 ensures the stability of the connection between the U-shaped component 3 and the adjusting mechanism 2.
[0033] Specifically, drill rod 1 provides the mounting base for adjustment mechanism 2. Adjustment mechanism 2 can move and be fixed on drill rod 1, and U-shaped part 3 connected to its rear side moves synchronously with it; connection mechanism 4 ensures that U-shaped part 3 and adjustment mechanism 2 are firmly connected, and together realize the position adjustment and stable connection of U-shaped part 3.
[0034] The adjusting mechanism 2 includes a movable ring 21, which forms the main frame of the adjusting mechanism 2. The ring structure fits snugly against the outside of the drill rod 1, providing mounting positions and support for other components of the adjusting mechanism 2. The inner wall of the movable ring 21 is fixedly connected to the outside of the drill rod 1. This fixed connection ensures that the movable ring 21 is stably fitted onto the drill rod 1, preventing it from shifting or shaking when moving on the drill rod 1. A limiting post 22 is fixedly connected to the front inner wall of the movable ring 21. The limiting post 22, through its fixed connection to the front inner wall of the movable ring 21, can move along with the movable ring 21. Sliding strips 24 are fixedly connected to the left and right inner walls of the movable ring 21. When the movable ring 21 moves on the drill rod 1, the sliding strips 24 can be embedded in the sliding grooves on both sides of the drill rod 1, forming a sliding fit with the grooves.
[0035] Specifically, the moving ring 21 of the adjustment mechanism 2 is fitted onto the drill rod 1 as the main frame, and the limiting post 22 on its front side moves with it. The sliding strips 24 on the left and right sides are embedded in the sliding groove of the drill rod 1 to form a sliding fit. This structure enables the moving ring 21 to move stably along the drill rod 1, providing support for other components and ensuring adjustment stability.
[0036] Two sliders 23 are fixedly connected to the inner front wall of the moving ring 21. When the limiting post 22 moves with the moving ring 21 or is adjusted in position, the sliders 23 slide in the groove, which can guide and support the movement of the limiting post 22. A control bar 25 is fixedly connected to the front of the limiting post 22. The operator can move the limiting post 22 by pulling or pushing the control bar 25, thereby controlling the position adjustment of the moving ring 21. A fixing component 26 is fixedly connected inside the moving ring 21. When the moving ring 21 moves the U-shaped part 3 to the target position, the fixing component 26 can cooperate with the limiting post 22 and other components to firmly fix the moving ring 21 to the drill rod 1.
[0037] Specifically, the slider 23 on the front side of the moving ring 21 serves as a guide support for the movement of the limiting post 22. The operator moves the limiting post 22 via the control bar 25 to adjust the position of the moving ring 21. The fixing component 26 inside the moving ring 21 cooperates with the limiting post 22 to fix the moving ring 21 at the target position, ensuring the stability of the U-shaped part 3.
[0038] Reference Figures 3 to 5 The connecting mechanism 4 includes two connecting columns 41. When the moving ring 21 moves on the drill rod 1, the connecting columns 41 move synchronously with it, thereby driving the U-shaped part 3 to move together, ensuring the consistency of movement between the U-shaped part 3 and the adjusting mechanism 2. A rotating shaft 42 is fixedly connected to the front interior of each of the two connecting columns 41. The rotating shaft 42 is fixed inside the connecting column 41, providing a pivot point for the rotation of the limiting semi-ring plate 43, allowing the limiting semi-ring plate 43 to rotate flexibly around it. Two limiting semi-ring plates 43 are fixedly connected to the exterior of each of the two rotating shafts 42. When tightened, they firmly fix the connecting column 41 to prevent it from loosening; when loosened, they facilitate the disassembly of the connecting column 41, thereby enabling the replacement of the U-shaped part 3.
[0039] Specifically, the two connecting posts 41 of the connecting mechanism 4 move synchronously with the moving ring 21, driving the U-shaped part 3 to move to maintain consistent movement; the rotating shaft 42 inside the connecting post 41 provides a rotation axis point for the limiting half-ring plate 43, and the limiting half-ring plate 43 achieves the fixing and replacement of the U-shaped part 3 by tightening or loosening the connecting post 41.
[0040] Each of the multiple limiting semi-ring plates 43 has a connecting block 44 fixedly connected to its front side. The connecting block 44 connects the limiting semi-ring plate 43 and the second rotating shaft 45, transmitting the movement of the limiting semi-ring plate 43 to the second rotating shaft 45, thus synchronizing their movements. The second rotating shaft 45 is fixedly connected to the front interior of each of the multiple connecting blocks 44. As an intermediate connector, it transmits the contraction force of the contraction column 46 and the tension force of the connecting rod 47 to the connecting block 44, thereby driving the limiting semi-ring plate 43 to rotate. The upper and lower ends of each of the multiple second rotating shafts 45 have contraction columns 46 fixedly connected inside. These columns contract when pulled by an external force and automatically reset after the external force disappears, providing power for the reset of the limiting semi-ring plate 43.
[0041] Specifically, the connecting block 44 on the front side of the limiting semi-ring plate 43 is connected to the rotating shaft 45 to achieve synchronous movement of the two; the rotating shaft 45 transmits the contraction force of the contraction column 46 and the tension of the connecting rod 47 to the connecting block 44, driving the limiting semi-ring plate 43 to rotate, while the contraction column 46 can retract and reset, providing power for the limiting semi-ring plate 43 to reset.
[0042] Each of the multiple rotating shafts 45 has a connecting rod 47 fixedly connected to its top. The connecting rod 47 connects the rotating shaft 45 and the connecting bar 49, transmitting the movement of the connecting bar 49 to the rotating shaft 45. The length and angle design ensures accurate force transmission direction. Two fixed chambers 48 are fixedly connected to the rear interior of the moving ring 21. The fixed chambers 48 provide installation space and protection for multiple components of the connecting mechanism 4, housing components such as the connecting block 44 and the retraction column 46 to prevent them from being interfered with or damaged by the external environment. Connecting bars 49 are rotatably connected to the opposite sides of the multiple connecting rods 47. The connecting bars 49 can rotate around the connecting rods 47 and the fixed shaft 402, serving to transmit force and change the direction of force.
[0043] Specifically, the connecting rod 47 at the top of the rotating shaft 45 connects to the connecting strip 49, accurately transmitting motion and force; the fixed compartment 48 on the rear side of the moving ring 21 stores and protects components such as the connecting block 44; the connecting strip 49 can rotate, transmit force and change direction, ensuring the linkage of all components of the connecting mechanism 4.
[0044] Each of the multiple connecting bars 49 has a fixed shaft 402 rotatably connected to one of its opposite sides. When the guide rod 401 moves, the fixed shaft 402 drives the connecting bars 49 to rotate, thereby pulling the connecting rod 47 through the connecting bars 49. Two guide rods 401 are fixedly connected to the rear interior of the moving ring 21. The guide rods 401 provide a track for the installation and movement of the fixed shaft 402 and the lower pressure plate 403, restricting the direction of movement so that it can only move up and down in a straight line. The top ends of the two guide rods 401 are fixedly connected to the lower pressure plate 403. By pressing the lower pressure plate 403, the operator drives the guide rods 401 downwards, thereby triggering the linkage of the entire connecting mechanism 4 and releasing the connecting column 41.
[0045] Specifically, the fixed shaft 402 on the opposite side of the connecting bar 49 moves with the guide rod 401, causing the connecting bar 49 to rotate and pull the connecting rod 47; the guide rod 401 restricts the fixed shaft 402 and the lower pressure plate 403 to move up and down in a straight line. When the operator presses the lower pressure plate 403, the connecting mechanism 4 can be triggered to release the connecting column 41.
[0046] Reference Figures 1 to 3 The fixing component 26 includes a fixing post 261, which, through its connection with the moving ring 21 and the limiting post 22, locks the position of the moving ring 21, preventing it from sliding freely during operation and ensuring the stability of the U-shaped part 3. The fixing post 261 is externally fixedly connected to the inside of the moving ring 21. When the moving ring 21 moves, the fixing post 261 moves synchronously with it, ensuring that it is locked in the required position. A limiting block 262 is fixedly connected to the top of the fixing post 261, increasing the strength of the connection between the fixing post 261 and the moving ring 21 and ensuring that the fixing post 261 will not detach from the inside of the moving ring 21 during operation.
[0047] Specifically, the fixing post 261 of the fixing component 26 connects the moving ring 21 and the limiting post 22, which can lock the position of the moving ring 21 to ensure the stability of the U-shaped part 3; the fixing post 261 moves synchronously with the moving ring 21, and the limiting block 262 at its top end enhances the connection with the moving ring 21 and prevents the fixing post 261 from falling off.
[0048] The limiting block 262 is externally fixedly connected to the inner wall of the top of the moving ring 21. This fixed connection creates a rigid connection between the limiting block 262 and the moving ring 21, further enhancing the stability of the fixed post 261 inside the moving ring 21. The bottom end of the fixed post 261 is externally fixedly connected to the inner front side of the limiting post 22. When the bottom end of the fixed post 261 is inserted into the inner front side of the limiting post 22, it prevents the limiting post 22 from continuing to move with the moving ring 21. Slide grooves are provided on both the left and right sides of the drill rod 1. These grooves provide a track for the sliding of the slide bar 24. Their shape and size match the slide bar 24, limiting its direction of movement and ensuring that it can only slide along the axial direction of the drill rod 1. The adjacent sides of the two slide bars 24 are slidably connected to the inner walls of both sides of the drill rod 1. This sliding connection ensures the flexibility of the moving ring 21's movement and, through the cooperation of the slide bars 24 and the slide grooves, prevents the moving ring 21 from rotating on the drill rod 1, ensuring that the direction of the U-shaped part 3 remains consistent.
[0049] Specifically, the limiting block 262 is rigidly connected to the inner wall of the top of the moving ring 21 to enhance the stability of the fixed column 261. The bottom end of the fixed column 261 is connected to the limiting column 22 to prevent the moving ring 21 from continuing to move. The first groove of the drill rod 1 is guided by the slide bar 24. The slide bar 24 slides with the inner wall of the drill rod 1 to ensure that the moving ring 21 can move flexibly and prevent it from rotating, thus ensuring that the U-shaped part 3 is in the same direction.
[0050] The rear external side of the limiting post 22 is fixedly connected to the inner wall of the drill rod 1. When the moving ring 21 moves to the target position, the fixed post 261 can precisely cooperate with the limiting post 22 to achieve locking. The limiting post 22 has two sliding grooves on its left and right sides. These grooves ensure that when the moving ring 21 drives the slider 23, the slider 23 can move smoothly along a preset trajectory, providing a guarantee for the smooth adjustment of the moving ring 21. The adjacent sides of the two sliders 23 are slidably connected to the inner walls of the limiting post 22 on both sides. When the moving ring 21 moves, the sliders 23 slide within the two sliding grooves, which guides the movement of the moving ring 21, preventing it from shifting or shaking during movement and ensuring the stability of the adjustment process.
[0051] Specifically, the rear side of the limiting post 22 is fixed to the inner wall of the drill rod 1, providing a base for the fixed post 261 to lock the moving ring 21; the sliding grooves on its left and right sides guide the slider 23 to move smoothly, and the slider 23 slides with the inner wall of the limiting post 22 to guide the moving ring 21 to prevent it from deviating and ensure smooth adjustment.
[0052] The rear sides of the two connecting columns 41 are fixedly connected to the front inner wall of the U-shaped part 3. When the connecting columns 41 are locked, the U-shaped part 3 can be stably fixed on the adjusting mechanism 2. The opposite sides of the multiple retractable columns 46 are fixedly connected to the inner walls of the two fixed chambers 48. The fixed connection provides a stable support point for the retractable columns 46, so that after the retractable columns 46 are contracted under tension, they can drive the rotating shaft 45 to return to its original position by their own elastic force. The front sides of the multiple connecting blocks 44 are slidably connected to the rear inner walls of the two fixed chambers 48, ensuring that the limiting semi-ring plate 43 can accurately achieve the clamping and loosening action of the connecting columns 41, and preventing the movement of the connecting blocks 44 from deviating from the preset trajectory and affecting the normal operation of the entire connecting mechanism 4.
[0053] Specifically, the two connecting columns 41 fix the U-shaped part 3 to the adjusting mechanism 2, ensuring that the U-shaped part 3 is stable when the connecting columns 41 are locked; the shrinking column 46 is fixed to the inner wall of the fixed chamber 48, and can drive the rotating shaft 45 to reset by elastic force after shrinking under force; the connecting block 44 slides on the inner wall of the fixed chamber 48, ensuring that the limiting semi-ring plate 43 accurately clamps or loosens the connecting column 41, ensuring the normal operation of the connecting mechanism 4.
[0054] Multiple fixed shafts 402 are externally fixedly connected to the inner walls of two guide rods 401. When the guide rods 401 move up and down, the fixed shafts 402 can move synchronously with them, thereby driving the connecting strip 49 to rotate, ensuring that the force can be effectively transmitted from the guide rods 401 to the connecting strip 49. Multiple limiting semi-ring plates 43 are externally slidably connected to the front inner walls of two connecting posts 41. When the limiting semi-ring plates 43 hug the connecting posts 41, the friction between them can prevent the connecting posts 41 from moving, thus fixing the U-shaped part 3.
[0055] Specifically, the fixed shaft 402 is fixed to the inner wall of the guide rod 401, moves up and down with the guide rod 401 and drives the connecting strip 49 to rotate, so as to realize the effective transmission of force; the limiting semi-ring plate 43 is slidably connected to the inner wall of the front side of the connecting column 41, and when it is tightened, the connecting column 41 is fixed by friction, thereby fixing the U-shaped part 3.
[0056] The implementation principle of this application embodiment is as follows: When it is necessary to adjust the position of the U-shaped part 3 on the drill rod 1, the moving ring 21 slides along the sliding grooves on both sides of the drill rod 1 through the sliding strips 24 on its left and right inner walls, driving the U-shaped part 3 and the connecting mechanism 4 fixedly connected to its rear side to move synchronously along the drill rod 1. At the same time, the limiting post 22 on the front inner wall of the moving ring 21 moves along the sliding grooves on the left and right sides of the limiting post 22 under the action of the slider 23 sliding along the sliding grooves on the left and right sides of the limiting post 22. After moving to the target position, the limiting post 22 is fixedly connected to the inside of the drill rod 1. At the same time, the fixing component 26 begins to play its role. Under the limiting action of the limiting block 262, the bottom end of the fixing post 261 is inserted into the front interior of the limiting post 22, thereby fixing the moving ring 21 to the corresponding position on the drill rod 1, thus completing the position adjustment of the U-shaped part 3. This satisfies the diverse requirements of the benchmark pile for the position of the U-shaped part 3 in different usage scenarios, and improves the practicality and adaptability of the equipment.
[0057] When it is necessary to replace the U-shaped part 3, the lower pressure plate 403 drives the guide rod 401 to move, the guide rod 401 drives the fixed shaft 402 to move, the fixed shaft 402 drives the connecting strip 49 to rotate, the connecting strip 49 drives the connecting rod 47 to move, the connecting rod 47 drives the rotating shaft 2 45 to move, the rotating shaft 2 45 drives the connecting block 44 and the shrinking column 46 to move, the connecting block 44 drives the limiting semi-ring plate 43 to rotate around the rotating shaft 1 42, so that the limiting semi-ring plate 43 slides out from the front inner wall of the connecting column 41, releasing the limitation on the connecting column 41, thereby releasing the connecting column 41 and realizing the convenient replacement of the U-shaped part 3. This makes the replacement process of the U-shaped part 3 more convenient and efficient, reduces the time and labor costs required for replacement, and improves the maintenance convenience of the benchmark pile.
