Abstract
Description
Technical Field
[0001] This utility model relates to the field of ground-based detection, specifically to a ground-based detection technology application device. Background Technology
[0002] Foundation testing is a comprehensive technology that assesses the load-bearing capacity of foundation soil through field tests, in-situ measurements, and laboratory analysis. Its core objective is to determine the properties of the foundation soil and identify characteristic values of the foundation's bearing capacity, providing a basis for engineering design. Foundation testing requires the use of detection devices.
[0003] For example, patent application CN 216899955 U discloses a foundation bearing capacity testing device for building construction, including a probe rod body and a support assembly for supporting the probe rod body. The support assembly includes a support plate, a guide hole, a support rod, a fixed base plate, a claw hook, and an adjustment assembly. This utility model's foundation bearing capacity testing device for building construction uses a support rod to support the support plate, and facilitates guiding the probe rod body through the guide hole on the support plate, effectively preventing the probe rod body from shifting position during the pressure application process.
[0004] Because the ground surface is not flat during foundation construction, the above-mentioned technology, which only uses a claw to grip the ground to support the probe, is unstable. When the hammer strikes, it will shake, causing the claw to slide on the ground and the entire detection device to tip over. Therefore, there is an urgent need in the market to develop a foundation detection technology application device to help people solve existing problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Please see Figures 1-4This utility model provides an embodiment of a ground detection technology application device, including a detection rod 1, a probe 101 fixedly connected to the lower end of the detection rod 1, a limiting seat 2 connected to the upper end of the detection rod 1, a falling hammer rod 202 fixedly connected to the upper end of the limiting seat 2, a hammer 204 provided on the falling hammer rod 202, a support base 3 provided at the lower middle part of the detection rod 1, a guide tube 301 fixedly connected to the middle of the support base 3, the lower middle part of the detection rod 1 passing through the interior of the guide tube 301, and a ring array rotating on the outer side of the lower end of the support base 3. Three support rods 4 are connected in a dynamic connection. An adjusting seat 5 is rotatably connected to one side of the lower end of each support rod 4. An internally threaded rotating tube 6 is rotatably connected to the middle of the adjusting seat 5. A screw 7 is installed inside the internally threaded rotating tube 6. The lower end of the screw 7 extends out of the lower end of the internally threaded rotating tube 6 and is fixedly connected to a chisel 701. The upper end of the screw 7 extends out of the upper end of the internally threaded rotating tube 6 and is fixedly connected to a rotating disk 703. The upper ends of all three support rods 4 are inserted into the support seat 3 and are rotatably connected via a first rotating shaft 401. One side of the adjusting seat 5 is fixed. A rotating connecting part 501 is connected, which is inserted into the lower end of the support rod 4 and rotatably connected through the second rotating shaft 502. The upper and lower ends of the internal thread rotating tube 6 extend out of the upper and lower end faces of the adjusting seat 5, respectively, and are fixedly connected to the limiting rings 601, so that the internal thread rotating tube 6 can rotate on the adjusting seat 5. The upper end of the internal thread rotating tube 6 passes through the inside of the upper limiting ring 601 and extends out of the upper end of the limiting ring 601. In use, the three support rods 4 are opened outward from the lower end of the supporting seat 3 by rotating the first rotating shaft 401. By pressing the rotating disk 703, the three screws 7 drive the drill rods 701 to be inserted into the ground for fixation. When the adjusting seat 5 is tilted, the internal thread rotating tube 6 is rotated, so that the internal thread rotating tube 6 is raised and lowered on the screws 7 through the threaded connection with the screws 7. When the internal thread rotating tube 6 is raised and lowered, the adjusting seat 5 is raised and lowered simultaneously, thereby causing the adjusting seat 5 to raise the support rods 4 in the tilt direction of the supporting seat 3, thereby achieving the leveling of the adjusting seat 5 and ensuring that the probe rod 1 is perpendicular to the ground.
[0024] Please see Figure 2 and Figure 4 The screw 7 is threadedly connected to the internally threaded rotating tube 6. The lower end of the drill rod 701 is fixedly connected to a spiral blade 702. When the rotating disk 703 is pressed, it can rotate synchronously, so that the rotating disk 703 drives the screw 7 and the drill rod 701 to rotate. When the drill rod 701 is inserted into the ground, it drives the spiral blade 702 to rotate synchronously. When the spiral blade 702 rotates, it is easy to drive the drill rod 701 to be inserted into the ground.
[0025] Please see Figure 2 and Figure 3The upper end of the outer end face of the probe rod 1 is fixedly provided with an external threaded part 102, and the middle part of the lower end face of the limit seat 2 is provided with an internal threaded hole 201. The upper end of the probe rod 1 is inserted into the internal threaded hole 201 and the external threaded part 102 is threadedly connected and fixed to the limit seat 2. The two can be separated by rotating the limit seat 2 or the probe rod 1, which is convenient for disassembly.
[0026] Please see Figure 2 and Figure 3 The upper end of the drop hammer rod 202 is fixedly connected to the limit plate 203. The hammer 204 has a through hole 205 in the middle. The drop hammer rod 202 passes through the through hole 205 in the middle of the hammer 204. Both sides of the hammer 204 are fixedly connected to the handles 206. The hammer 204 is pulled up on the drop hammer rod 202 by the handles 206. Then, the handles 206 are released, so that the hammer 204 falls and hits the limit seat 2. The limit seat 2 causes the detection rod 1 to descend, and the detection rod 1 causes the probe 101 to be inserted into the ground for detection.
[0027] Working Principle: In use, the three support rods 4 are first extended outwards from the lower end of the support base 3 to form a triangular support structure. Then, the rotating disk 703 is pressed to insert the drill rod 701 into the ground. Simultaneously, the rotating disk 703 rotates, driving the screw 7 and the helical blade 702 to rotate, enhancing the grip of the drill rod 701. When the adjusting seat 5 tilts, the internal thread rotating tube 6 is rotated, causing it to rise and fall on the screw 7 through its threaded connection. The rising and falling of the internal thread rotating tube 6 synchronously drives the adjusting seat 5 to rise and fall, thereby raising the support rods 4 in the tilt direction of the support base 3, achieving leveling of the adjusting seat 5, and ensuring that the probe rod 1 is perpendicular to the ground. After leveling, the operator holds the handle 206 to raise the hammer 204 to the upper part of the drop hammer rod 202. After release, the hammer 204 falls freely to strike the limiting seat 2. The impact force is transmitted through the probe rod 1 to the probe 101, penetrating the foundation. The foundation bearing capacity is assessed by measuring the penetration depth through multiple hammer blows. After the detection is completed, the detection rod 1 can be disassembled for maintenance or replacement by rotating the limiting seat 2 in the reverse direction. This device effectively overcomes the shaking problem caused by uneven ground through a three-point adaptive leveling mechanism, improving detection accuracy and safety.
