Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a precision positioning system for pile drivers used in building construction. Background Technology

[0002] Building construction refers to a series of activities that transform design drawings into actual buildings. It encompasses multiple stages, from site preparation and foundation construction to main structure construction and decoration. For example, in piling operations, the positioning device of a piling machine is used to determine the location of the piles, and through various mechanical and manual operations, the piles are accurately driven into the ground to provide a stable foundation for the building. The construction process must strictly adhere to relevant specifications and standards, involving multiple professional technologies such as earthwork engineering, concrete engineering, and steel structure engineering. It is a complex and systematic project aimed at creating building products that meet functional and quality requirements.

[0003] During piling, a positioning system and corresponding devices are needed to position the piling machine and prevent the drill rod from tilting or deviating. However, current precision positioning systems for piling machines used in construction engineering have the following drawbacks: Insufficient versatility: Many current precision positioning systems for piling machines struggle to effectively fix drill rods of different sizes, limiting their adaptability. When a construction project involves multiple specifications of drill rods, frequent adjustments or replacements are necessary, impacting construction efficiency and failing to meet complex and ever-changing engineering needs. Inconvenient maintenance: Damage to the fixing structure can easily lead to system failure. Replacement is complex, time-consuming, and labor-intensive, and untimely repairs may delay the construction schedule and increase costs. The system is particularly disadvantageous in emergency repair scenarios.

[0004] In response to this technical problem, this application proposes a precision positioning system for pile drivers used in building construction. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in effectively fixing drill rods of different sizes and the difficulty in replacing the fixing structure. The proposed system is a precision positioning system for pile drivers used in construction engineering. This system aims to fix drill rods of different sizes, improve the system's versatility, facilitate the replacement of different fixing structures by workers as needed, and prevent system failure due to damage to the fixing structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A precision positioning system for a pile driver used in building construction includes a base and a pile driver. A drill rod is mounted on the drive end of the pile driver, and a hydraulic lifting column is mounted on the top side of the pile driver. A lifting seat is fixedly connected to the top of the hydraulic lifting column. A slider is connected inside the lifting seat via an adjusting component, which adjusts the position of the slider. A dovetail groove is formed inside the slider, and a dovetail plate is interference-fitted inside the dovetail groove. A clamping plate for positioning the drill rod is fixedly connected to the outer wall of the dovetail plate. A fixing component is provided inside the slider to fix the dovetail plate into the dovetail groove.

[0008] Furthermore, the adjustment assembly includes a bidirectional screw and a limiting rod disposed inside the lifting seat. The bidirectional screw is rotatably connected inside the lifting seat, and the limiting rod is fixedly connected inside the lifting seat.

[0009] Furthermore, the bidirectional screw is threaded inside the slider, and the limiting rod is slidably connected inside the slider.

[0010] Furthermore, a helical gear is fixedly connected to the outer wall of the bidirectional screw, and the two helical gears mesh with each other. A motor is installed on the right side of the lifting seat, and the drive end of the motor is fixedly connected to the right end of the top bidirectional screw.

[0011] Furthermore, the fixing component includes a first baffle and a second baffle slidably connected inside the slider, the second baffle being inserted inside the first baffle, and the first baffle and the second baffle being located above the dovetail groove.

[0012] Furthermore, a fixing tube is fixedly connected to the outer wall of the slider, and an insert rod is slidably connected inside the fixing tube. The insert rod is inserted into the inside of the first baffle and the second baffle.

[0013] Furthermore, the insert has an internal threaded connection to a threaded rod, and the end of the fixed tube is rotatably connected to a handle via a damping shaft. The end of the threaded rod is rotatably connected inside the fixed tube, and the end of the threaded rod is fixedly connected inside the handle.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, two meshing helical gears enable the upper and lower bidirectional screws to rotate synchronously, thereby simultaneously adjusting the distance between the upper and lower sets of sliders. This allows the distance between the clamping plates to be adjusted, enabling the system to fix drill rods of different sizes and improving the system's versatility.

[0016] In this invention, by inserting the dovetail plate into the dovetail groove, the dovetail plate and the dovetail groove are interference-fitted together. By sliding the first baffle and the second baffle above the dovetail plate and fixing the first baffle and the second baffle together with the insert rod, the clamp is fixed to the slider. This makes the fixing structure easy to disassemble, allowing the staff to replace different fixing structures as needed, and preventing the entire system from failing due to damage to the fixing structure.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-3 This utility model provides an embodiment of a precise positioning system for a pile driver used in building construction, comprising a base 1 and a pile driver 5. A drill rod 4 is installed at the drive end of the pile driver 5, which drives the drill rod 4 into the ground. A hydraulic lifting column 2 is installed on the top side of the pile driver 5, and a lifting seat 3 is fixedly connected to the top of the hydraulic lifting column 2. The height of the lifting seat 3 is adjusted by the hydraulic lifting column 2. A slider 7 is connected inside the lifting seat 3 via an adjusting component 19, which adjusts the position of the slider 7. (Refer to...) Figure 6 and Figure 7 The slider 7 has a dovetail groove inside, and a dovetail plate 15 is interference-fitted inside the dovetail groove. A clamping plate 8 for positioning the drill rod 4 is fixedly connected to the outer wall of the dovetail plate 15. The clamping plate 8 is fixed to the slider 7 by inserting the dovetail plate 15 into the dovetail groove. The slider 7 has a fixing component 20 inside, which fixes the dovetail plate 15 into the dovetail groove. (Refer to...) Figure 4 and Figure 5 The adjusting assembly 19 includes a bidirectional screw 9 and a limiting rod 10 disposed inside the lifting seat 3. The bidirectional screw 9 is rotatably connected inside the lifting seat 3, and the limiting rod 10 is fixedly connected inside the lifting seat 3. The bidirectional screw 9 is threadedly connected inside the slider 7, and the limiting rod 10 is slidably connected inside the slider 7. The bidirectional screw 9 drives the two opposing sliders 7 to slide, thereby adjusting the distance between the two sliders 7. A helical gear 11 is fixedly connected to the outer wall of the bidirectional screw 9. The two helical gears 11 mesh with each other, and the two bidirectional screws 9 rotate synchronously through the meshing helical gears 11, so that the upper and lower sliders 7 can be adjusted simultaneously. A motor 6 is installed on the right side of the lifting seat 3. The drive end of the motor 6 is fixedly connected to the right end of the top bidirectional screw 9, and the top bidirectional screw 9 is driven to rotate through the bidirectional screw 9.

[0029] Reference Figures 6-8The fixing component 20 includes a first baffle 13 and a second baffle 14 slidably connected inside the slider 7. The second baffle 14 is inserted into the inside of the first baffle 13. The first baffle 13 and the second baffle 14 are located above the dovetail groove. By sliding the first baffle 13 and the second baffle 14 above the dovetail groove, and simultaneously inserting the second baffle 14 into the first baffle 13, the dovetail plate 15 is blocked in the dovetail groove by the first baffle 13 and the second baffle 14, preventing the dovetail plate 15 from detaching from the dovetail groove. A fixing tube 12 is fixedly connected to the outer wall of the slider 7. A plug rod 16 is slidably connected inside the fixing tube 12. The plug rod 16 is inserted into the first baffle 13 and the second baffle 14. Inside the tube, the insertion rod 16 is inserted into the first baffle 13 and the second baffle 14, connecting the first baffle 13 and the second baffle 14 together to prevent the dovetail groove from being exposed due to separation of the first baffle 13 and the second baffle 14. The insertion rod 16 is internally threaded with a threaded rod 17. The end of the fixed tube 12 is rotatably connected to a handle 18 through a damping shaft. The end of the threaded rod 17 is rotatably connected inside the fixed tube 12, and the end of the threaded rod 17 is fixedly connected inside the handle 18. The threaded rod 17 is rotated by the handle 18, thereby driving the insertion rod 16 to slide, so that the insertion rod 16 is inserted into or disengaged from the first baffle 13 and the second baffle 14.

[0030] Working Principle: First, the base 1 is moved to the location where piling is required. Then, the piling machine 5 lifts the drill rod 4 into the lifting seat 3, positioning it between the clamping plates 8. Next, the hydraulic lifting column 2 is activated to raise the lifting seat 3, moving it to the top of the drill rod 4 and placing it against the bottom of the drive end of the piling machine 5. Then, parameters are set according to the size of the drill rod 4. The motor 6 is then activated to drive the double-sided screw 9 on the top side to rotate according to these parameters. Simultaneously, the helical gear 11 meshes with the screw 9 on the bottom side, driving it to rotate synchronously. This adjusts the distance between the two sliders 7 on the same layer, thereby adjusting the distance between the clamping plates 8 and causing the clamping plates 8 to move towards the drill rod 4, clamping it in place. Then, the piling machine can begin operation. The pile driver 5 drives the drill rod 4 into the ground. As the drill rod 4 moves downward, the hydraulic lifting column 2 is activated simultaneously to move the lifting seat 3 downward to keep the drill rod 4 fixed. After the pile driving is completed, the motor 6 is activated to drive the slider 7 to move, thereby disengaging the clamping plate 8 from the drill rod 4, thus completing the pile driving. When the clamping plate 8 needs to be replaced, first turn the handle 18 to rotate the threaded rod 17, thereby driving the insertion rod 16 to slide, so that the insertion rod 16 disengages from the first baffle 13 and the second baffle 14. Then slide the first baffle 13 and the second baffle 14 to expose the dovetail groove. Then pull the dovetail plate 15 out of the dovetail groove, thereby removing the clamping plate 8 from the slider 7. Then repeat the above operation in reverse to install the new clamping plate 8 onto the slider 7.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
