Description

Technical Field

[0001] This utility model relates to the field of soil and rock bearing capacity testing technology, and in particular to a retractable soil and rock bearing capacity testing device. Background Technology

[0002] Soil and rock bearing capacity testing is the process of assessing the maximum supporting capacity that soil or rock can provide when bearing the loads of structures such as buildings, bridges, and roads. This test is crucial for ensuring the safety, stability, and economy of engineering projects.

[0003] For example, a foundation bearing capacity testing device with publication number CN222477403U includes a base plate, a testing frame, a height adjustment component, and a testing component. The testing frame is located in the middle of the top wall of the base plate, the height adjustment component is located inside the upper part of the testing frame, and the testing component is located inside the testing frame and connected to the height adjustment component. The height adjustment component includes a drive motor and a rotating shaft. A drive cavity is provided at the top of the testing frame, and the drive motor is located on one side of the drive cavity. This invention uses a motor to drive the reel to rotate, releasing the winding of the suspension rope onto the punch head. The punch head then moves down to impact the bearing block, and the testing rod moves down to insert into the foundation. However, because the device connects the punch head through a suspension rope, it is prone to shaking due to external factors during the unwinding process, resulting in inconsistent impact points each time, which affects the test results.

[0004] Therefore, it is necessary to design a retractable soil and rock bearing capacity testing device that can automatically clamp, lift, and release the striking block while guiding it to ensure that the striking block hammer always lands in the same position, thus ensuring the accuracy of the test. Utility Model Content

[0005] To overcome the shortcomings of existing technologies that connect the punching head with a suspension rope, which are prone to shaking due to external factors during unwinding, resulting in inconsistent impact points and affecting test results, this invention provides a retractable soil and rock bearing capacity testing device that can automatically clamp, lift, and release the striking block while guiding it, ensuring that the hammer landing point of the striking block is always in the same position, thus ensuring the accuracy of the test.

[0006] The technical implementation scheme of this utility model is as follows: a retractable soil bearing capacity testing device, including a base, a folding frame, a connecting plate, a test rod, a multi-section telescopic rod, a connecting frame, a hydraulic rod, a striking block, and a clamping assembly. The folding frame is rotatably provided on the front and rear parts of the base, and the connecting plate is rotatably connected between the folding frames. The test rod is placed in the middle of the base and passes through the connecting plate. Two multi-section telescopic rods are connected to the upper sides of the front and rear parts of the connecting plate. The telescopic ends of the multi-section telescopic rods are connected to the connecting frame. The hydraulic rods are connected to the upper sides of the front and rear parts of the base. The hydraulic rods are electrically connected to the processor through a control module. The telescopic ends of the hydraulic rods are connected to the connecting plate. A striking block is placed on the upper side of the test rod and passes through the bottom of the connecting frame. The striking block is slidably connected to the connecting frame. The connecting frame is provided with a clamping assembly that can automatically clamp, lift, and release the striking block.

[0007] Furthermore, multiple mounting holes are provided on both the left and right sides of the base.

[0008] Furthermore, a guide hole is provided in the middle of the connecting plate.

[0009] Furthermore, the clamping assembly includes a motor, a reciprocating lead screw, a guide rod, a connecting block, a spring, a clamping block, and a pressing block. The motor is connected to the upper right side of the connecting frame. The motor and the processor are electrically connected through a control module. The reciprocating lead screw is connected to the output shaft of the motor. The reciprocating lead screw is rotatably connected to the connecting frame. The guide rod is connected to the front right side of the connecting frame. The connecting block is threadedly connected to the reciprocating lead screw. The guide rod is slidably connected to the connecting block. Two clamping blocks are slidably connected to the left side of the connecting block. Springs are connected between the left and right sides of the clamping blocks and the connecting blocks. A pressing block is connected to the inner upper part of the connecting frame.

[0010] Furthermore, notches are cut into all the clamping blocks.

[0011] Furthermore, the extruded block has a triangular structure.

[0012] The beneficial effects are as follows: 1. This utility model uses a clamping block to move downwards and contact the right side of the striking block. The clamping block holds the striking block, and after the connecting block moves upwards to a certain position, the squeezing block squeezes the clamping block, causing the clamping block to move outwards. This makes the striking block hammer towards the test rod, achieving the effect of automatically clamping, lifting, and releasing the striking block while guiding it, ensuring that the hammer landing point of the striking block is always in the same position, and ensuring the accuracy of the test.

[0013] 2. This utility model activates the hydraulic rod, which drives the connecting plate upward, causing the folding frame to rotate and unfold, thus adjusting the height of the striking block. This allows for convenient adjustment of the striking block's height, facilitating the use of test rods of different lengths for drop hammer testing. Attached Figure Description

Detailed Implementation

[0020] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] A retractable soil and rock bearing capacity testing device, such as Figures 1-5 As shown, the device includes a base 1, a folding frame 2, a connecting plate 3, a test rod 4, a multi-section telescopic rod 5, a connecting frame 6, a hydraulic rod 7, a striking block 11, and a clamping assembly. The base 1 has four mounting holes on both its left and right sides for easy installation and fixation. The base 1 has folding frames 2 rotatably mounted on its front and rear sides, with a connecting plate 3 rotatably connecting the folding frames 2. The test rod 4 is placed in the middle of the base 1, passing through the connecting plate 3. A guide hole is provided in the middle of the connecting plate 3 to facilitate the passage of the test rod 4. Two multi-section telescopic rods 5 are connected to the upper sides of both the front and rear sides of the connecting plate 3, with a connecting frame 6 connecting the telescopic ends of the multi-section telescopic rods 5. Hydraulic rods 7 are connected to the upper sides of both the front and rear sides of the base 1, and each hydraulic rod 7 is electrically connected to the processor via a control module. The telescopic ends of the hydraulic rods 7 are connected to the connecting plate 3. A striking block 11 is placed on the upper side of the test rod 4, passing through the bottom of the connecting frame 6 and slidably connected to it. A clamping assembly is provided on the connecting frame 6.

[0022] like Figure 4 and Figure 5As shown, the clamping assembly includes a motor 8, a reciprocating lead screw 9, a guide rod 10, a connecting block 12, a spring 13, a clamping block 14, and a pressing block 15. The motor 8 is connected to the upper right side of the connecting frame 6. The motor 8 and the processor are electrically connected through a control module. The reciprocating lead screw 9 is connected to the output shaft of the motor 8. The reciprocating lead screw 9 is rotatably connected to the connecting frame 6. The guide rod 10 is connected to the front right side of the connecting frame 6. The connecting block 12 is threaded onto the reciprocating lead screw 9. The guide rod 10 is slidably connected to the connecting block 12. The left side of the connecting block 12 is slidably connected to two clamping blocks 14. Each clamping block 14 has a notch to facilitate the pressing block 15 pressing the clamping block 14. Springs 13 are connected between the left and right sides of the clamping block 14 and the connecting block 12. The pressing block 15 is connected to the inner upper part of the connecting frame 6. The pressing block 15 has a triangular structure to facilitate the pressing of the clamping block 14.

[0023] When using this device, first install the base 1 onto the soil bearing capacity testing area, then pass the test rod 4 through the connecting plate 3 and the base 1, so that the test rod 4 is inserted into the test ground. Then, the processor starts the motor 8 through the control module, driving the reciprocating screw 9 to rotate, causing the connecting block 12 to move downward along the guide rod 10 under the action of the thread, so that the clamping block 14 moves downward to contact the right side of the striking block 11. At this time, the clamping block 14 moves outward, and the spring 13 is compressed and contracted. After moving to a certain position, the spring 13 returns to its original position, driving the clamping block 14 to move and reset, so that the clamping block 14 clamps the right side of the striking block 11, and then... The multi-lead screw 9 continues to rotate, driving the connecting block 12 to move upward, causing the striking block 11 to move upward along the connecting frame 6. When the connecting block 12 moves upward to a certain position, the pressing block 15 will press the notch on the clamping block 14, causing the clamping block 14 to move outward. The spring 13 is compressed and contracts, causing the striking block 11 to hammer vertically downward along the connecting frame 6 onto the test rod 4, causing the test rod 4 to insert into the ground for testing. The multi-section telescopic rod 5 retracts along with it, thus automatically clamping, lifting and releasing the striking block 11 while guiding it, ensuring that the hammering point of the striking block 11 is always in the same position, ensuring the accuracy of the test.

[0024] When different lengths of test rods 4 are required, the hydraulic rod 7 can be activated to move the connecting plate 3 upward, causing the folding frame 2 to rotate and unfold, adjusting the height of the striking block 11. This allows for easy adjustment of the height of the striking block 11, facilitating the use of test rods 4 of different lengths for drop hammer testing.
