Description

Technical Field

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

[0002] Foundation bearing capacity testing refers to the process of assessing the ability of soil or rock strata to support buildings or other structures through a series of tests and analysis methods. Foundation bearing capacity refers to the maximum load that a unit area of ​​foundation can withstand without causing shear failure or excessive settlement.

[0003] A foundation bearing capacity testing device, such as the one disclosed in publication number CN218233582U, includes a base, a lifting mechanism, and a force-applying mechanism. A support plate is mounted on the surface of the base. The lifting mechanism includes a drive component and a first steel rope. The movable end of the drive component is fixedly connected to the first steel rope. A lifting component is mounted on the first steel rope, and a probe is mounted on the surface of the lifting component. The force-applying mechanism includes a rotating component and a second steel rope. The movable end of the rotating component is fixedly connected to one end of the second steel rope, and a force-applying component is mounted on the other end of the second steel rope. This device uses the cooperation between the rotating component on the horizontal plate and the second steel rope to drive the probe into the foundation through a through-hole. However, when unwinding the second steel rope, the force-applying component is easily affected by wind, causing it to sway. This results in inconsistent force points during each hammer drop, affecting the foundation bearing capacity testing results. Furthermore, the speed of the second motor during unwinding the second steel rope can also affect the force of the free-falling hammer, thus impacting the foundation bearing capacity testing.

[0004] Therefore, it is necessary to design a foundation bearing capacity testing device that can automatically clamp, lift, and release the striking block while guiding it to ensure detection accuracy and avoid different stress points with each strike. Utility Model Content

[0005] To overcome the shortcomings of existing foundation bearing capacity testing equipment, such as the swaying of the force-applying component due to wind during the unwinding of the second steel rope, resulting in inconsistent force points with each hammer drop and affecting the test results, and the influence of the second motor's drive speed during unwinding of the second steel rope on the force-applying component's free-falling force, thus affecting the foundation bearing capacity test, this invention provides a foundation bearing capacity testing device that can automatically clamp, lift, and release the striking block while guiding it, ensuring testing accuracy and avoiding inconsistent force points with each strike.

[0006] The technical solution of this utility model is: a foundation bearing capacity testing device, including a base, a rod, a support frame, a force probe, a triggering component, and a striking component. Two rods are placed on the left and right sides of the base, and a support frame is connected to the upper side of the base. A force probe is placed in the front middle part of the base. The support frame is equipped with a triggering component that can adjust the height of the free fall hammer. The middle part of the base is equipped with a striking component that can automatically strike and clamp.

[0007] Furthermore, the lower part of the insertion rod is a tapered structure.

[0008] Furthermore, it also includes casters, with multiple casters rotatably connected to the lower part of the base.

[0009] Furthermore, the triggering component includes an electric actuator, a slide rail, and protrusions. The electric actuator is connected to the upper part of the support frame. The electric actuator and the processor are electrically connected through a control module. The slide rail is connected to the telescopic end of the electric actuator, and two protrusions are connected to the upper inner side of the slide rail.

[0010] Furthermore, it also includes a striking assembly, which includes a motor, a lead screw, a sliding frame, clamping blocks, connecting parts, a telescopic spring, and striking blocks. The motor is connected to the center of the base, and the motor and the processor are electrically connected through a control module. A lead screw is connected to the output shaft of the motor, and the lead screw is rotatably connected to the support frame. A sliding frame is threaded onto the lead screw, and the sliding frame is slidably connected to the slide rail. Clamping blocks are rotatably connected to both the left and right sides of the sliding frame, and connecting parts are rotatably connected to the sides of the clamping blocks that are close to each other. Telescopic springs are connected between the connecting parts, and striking blocks are engaged between the clamping blocks. The striking blocks are slidably connected to the slide rail.

[0011] Furthermore, it also includes guide wheels. The front part of the base is rotatably connected to two guide wheels, both of which are in contact with the force-bearing probe.

[0012] The beneficial effects are: 1. As the sliding frame continues to move downward, the clamping block rotates to clamp the striking block. The clamping block moves upward and is squeezed by the protrusion, causing the clamping block to rotate. This makes the striking block move downward along the slide rail to strike the force probe. This achieves the effect of automatically clamping, lifting and releasing the striking block while guiding it, ensuring detection accuracy and avoiding different force points each time it is struck.

[0013] 2. This utility model uses an electric actuator to move the slide rail up and down, causing the protrusion to move up and down. By adjusting the height of the protrusion, the trigger height for the clamp to release can be adjusted, thus achieving the effect of adjusting the trigger height for the clamp to release, which is convenient to adapt to different detection needs.

Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] A foundation bearing capacity testing device, such as Figures 1-3 As shown, it includes a base 1, movable wheels 2, insertion rods 3, support frame 4, force probe 15, guide wheels 16, triggering component, and striking component. The lower part of the base 1 is rotatably connected to four movable wheels 2. The left and right sides of the base 1 are equipped with two insertion rods 3, one in front and one in back. The lower part of the insertion rods 3 are tapered to facilitate insertion into the ground. The upper side of the base 1 is connected to the support frame 4. The force probe 15 is placed in the front middle part of the base 1. The front middle part of the base 1 is rotatably connected to two guide wheels 16, both of which are in contact with the force probe 15. The support frame 4 is equipped with a triggering component, and the middle of the base 1 is equipped with a striking component.

[0022] like Figures 1-4 As shown, the triggering component includes an electric actuator 5, a slide rail 6, and a protrusion 7. The electric actuator 5 is connected to the upper part of the support frame 4. The electric actuator 5 and the processor are electrically connected through the control module. The slide rail 6 is connected to the telescopic end of the electric actuator 5. Two protrusions 7 are connected to the upper inner side of the slide rail 6.

[0023] like Figures 1-5As shown, it also includes a striking assembly, which includes a motor 8, a lead screw 9, a sliding frame 10, a clamping block 11, a connecting piece 12, a telescopic spring 13, and a striking block 14. The motor 8 is connected to the middle of the base 1. The motor 8 and the processor are electrically connected through a control module. The lead screw 9 is connected to the output shaft of the motor 8. The lead screw 9 is rotatably connected to the support frame 4. The sliding frame 10 is threadedly connected to the lead screw 9. The sliding frame 10 is slidably connected to the slide rail 6. The left and right sides of the sliding frame 10 are rotatably connected to the clamping blocks 11. The side of the clamping blocks 11 that is close to each other is rotatably connected to the connecting piece 12. The telescopic spring 13 is connected between the connecting pieces 12. The striking block 14 is snapped between the clamping blocks 11. The striking block 14 is slidably connected to the slide rail 6.

[0024] When using this equipment, first move the base 1 to the foundation bearing capacity testing area using the casters 2 for assisted movement. Then, insert the rod 3 into the ground to fix the base 1. Next, start the motor 8, which drives the lead screw 9 to rotate, causing the sliding frame 10 to move downwards under the action of the thread. This moves the clamping block 11 downwards. When the clamping block 11 moves downwards and contacts the striking block 14, it will rotate, causing the connecting piece 12 to rotate on the clamping block 11. The telescopic spring 13 is compressed and contracted. When the sliding frame 10 continues to move downwards, the telescopic spring 13 returns to its original position, causing the clamping block 11 to rotate. The clamping block 11 then acts on the striking block 14. The device is clamped, and then the sliding frame 10 is moved upward by the screw 9 through the screw thread, which in turn moves the clamping block 11 upward. After moving to a certain height, the clamping block 11 is squeezed by the protrusion 7, which causes the upper part of the clamping block 11 to rotate inward, so that the striking block 14 is disengaged from the clamping block 11. The striking block 14 moves downward along the slide rail 6 to strike the force probe 15, which in turn moves the force probe 15 downward, causing the guide wheel 16 to rotate. The guide wheel 16 guides the force probe 15 to prevent tilting, so that the striking block 14 can be automatically clamped, lifted and released while being guided, ensuring detection accuracy and avoiding different force points each time it is struck.

[0025] When it is necessary to adjust the height of the drop hammer, the electric actuator 5 can be activated to move the slide rail 6 up and down, causing the protrusion 7 to move up and down. By adjusting the height of the protrusion 7, the trigger height for the release of the clamp 11 can be adjusted, thus making it easier to adapt to different testing needs.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
