Description
Technical Field
[0001] This utility model relates to the field of foundation testing technology, and in particular to a precise engineering foundation bearing capacity testing device. Background Technology
[0002] In the field of engineering construction, the foundation, as the basis of the entire building structure, is crucial for ensuring project quality and safety through accurate assessment of its bearing capacity. Before construction begins, the foundation's bearing capacity must be precisely tested to determine if it meets design requirements. In urban areas, if the foundation bearing capacity of high-rise residential buildings is insufficient, serious safety hazards such as settlement, tilting, or even collapse may occur. Using this testing device allows for precise acquisition of foundation bearing capacity data in the early stages of construction, helping engineers to rationally design foundation reinforcement schemes or adjust building structural designs, ensuring the stability and safety of the building.
[0003] In existing technologies, most testing devices face significant challenges when frequently changing testing points at construction sites. Due to structural limitations and a lack of effective mobility aids, the relocation process is extremely difficult, incurring substantial manpower and time costs. Furthermore, once the device is moved to a new testing point, it is difficult to place it quickly and stably on the ground, and any shaking or instability can severely affect the accuracy of the testing data. In addition, existing testing devices have significant shortcomings in terms of testing accuracy, failing to accurately detect subtle changes in the foundation under different pressures. This results in a large discrepancy between the testing results and the actual bearing capacity of the foundation, posing potential risks to the construction project. Utility Model Content
[0004] The purpose of this invention is to solve the problems in the prior art, such as the difficulty in moving the device when changing the detection points, the difficulty in stabilizing the device after moving it, and the difficulty in accurately detecting the device during use. Therefore, this invention proposes a precise engineering foundation bearing capacity testing device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a precision engineering foundation bearing capacity testing device, comprising a testing frame, a lifting device fixedly connected to the top of the testing frame, a gravity hammer fixedly connected to the bottom of the lifting device, a base plate fixedly connected to the bottom of the testing frame, a connecting frame fixedly connected to the top of the base plate, a testing component slidably connected to the surface of the connecting frame, a sliding groove provided on the side of the testing frame, a groove provided at the bottom end of the side of the testing frame, a fixing structure fixedly connected to the bottom end of the side of the testing frame, the fixing structure comprising a fixing plate, a screw threadedly connected to the inside of the fixing plate, and a support plate rotatably connected to the bottom end of the screw.
[0006] Furthermore, the lifting device includes a connecting block, which is fixedly connected to the top of the inspection frame. A motor is fixedly connected to the side of the connecting block, and a roller is fixedly connected to the output end of the motor.

A pull rope is fixedly connected to the outer side of the roller, and a lifting plate is fixedly connected to the bottom end of the pull rope. The gravity hammer is fixedly connected to the bottom of the lifting plate.
[0007] Furthermore, both ends of the lifting plate are fixedly connected to locking blocks, and the sides of the locking blocks are fixedly connected to connecting rods, and the locking blocks are slidably connected within the sliding grooves.
[0008] Furthermore, the detection assembly includes a mounting plate that is slidably connected to a connecting frame. A connecting ring is fixedly connected to one end of the mounting plate away from the connecting frame. A detection rod is fixedly connected to the inner wall of the connecting ring. A load-bearing plate is fixedly connected to the top of the detection rod. A detection sensor is provided at the bottom of the outer surface of the detection rod.
[0009] Furthermore, the support plate includes a T-shaped plate, which is connected through the groove. A fixing pile is fixedly connected to the bottom end of the T-shaped plate, and the fixing structure is symmetrically distributed on the side of the testing frame.
[0010] Furthermore, a hole is provided in the center of the top surface of the base plate, and a movable wheel is fixedly connected to the bottom of the base plate.
[0011] Furthermore, the detection rod passes through the hole to detect the foundation.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, by setting movable wheels at the bottom of the base plate, the ease of movement of the device when changing test points is greatly improved, and the labor and time costs are reduced; at the same time, by setting a fixed structure, the height of the support plate can be adjusted by rotating the screw, and the fixed stake can be inserted into the ground, so that the device can be placed stably after being moved to a new test point, effectively reducing the impact of device shaking on the test results. This fixed structure solves the problems of difficulty in moving when changing test points and difficulty in placing the device stably after moving.
[0014] 2. In this utility model, by setting the detection components, the locking block and sliding groove in the lifting device ensure the stability of the vertical impact of the gravity hammer, which significantly improves the accuracy of the detection. During use, the operation of the motor drives the rotation of the roller, which causes the pull rope to be released and retracted.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a precise engineering foundation bearing capacity testing device, including a testing frame 1, a lifting device 2 fixedly connected to the top of the testing frame 1, a gravity hammer 5 fixedly connected to the bottom of the lifting device 2, a base plate 3 fixedly connected to the bottom of the testing frame 1, a connecting frame 6 fixedly connected to the top of the base plate 3, a testing component 7 slidably connected to the surface of the connecting frame 6, a sliding groove 11 provided on the side of the testing frame 1, a groove 12 provided at the bottom end of the side of the testing frame 1, and a fixing structure 4 fixedly connected to the bottom end of the side of the testing frame 1.
[0023] The following section will describe in detail the specific setup and function of its fixed structure 4 and lifting device 2.
[0024] In this embodiment: the fixing structure 4 includes a fixing plate 41, the fixing plate 41 is internally threaded with a screw 42, and the bottom end of the screw 42 is rotatably connected to a support plate 43.
[0025] The effect achieved by the above components is as follows: when the device is moved to the designated detection point, by rotating the screw 42, which is threadedly connected to the fixed plate 41, the screw 42 will move up and down within the fixed plate 41. Because the bottom end of the screw 42 is rotatably connected to the support plate 43, the up and down movement of the screw 42 drives the support plate 43 to adjust its height, so that the device can remain level even on uneven ground, reducing errors during detection.
[0026] In this embodiment: the lifting device 2 includes a connecting block 21, which is fixedly connected to the top of the detection frame 1. A motor 22 is fixedly connected to the side of the connecting block 21. A winding roller 23 is fixedly connected to the output end of the motor 22. A fixing block 24 is rotatably connected to the end of the winding roller 23 away from the connecting block 21. A pull rope 26 is fixedly connected to the outside of the winding roller 23. A lifting plate 25 is fixedly connected to the bottom end of the pull rope 26. A gravity hammer 5 is fixedly connected to the bottom of the lifting plate 25.
[0027] The effect achieved by the above components is as follows: after the motor 22 is powered on and started, its output shaft drives the roller 23 to rotate around the fixed block 24. As the roller 23 rotates, the pull rope 26 winds around or unwinds on the roller 23, thereby driving the lifting plate 25 to move up and down in the vertical direction. Since the gravity hammer 5 is fixed to the bottom of the lifting plate 25, the gravity hammer 5 will also move up and down accordingly.
[0028] Specifically, both ends of the lifting plate 25 are fixedly connected to a locking block 251, and a connecting rod 252 is fixedly connected to the side of the locking block 251. The locking block 251 slides within the slide groove 11.
[0029] The effect achieved by the above-mentioned components is that during the up-and-down movement of the lifting plate 25, the locking block 251 slides along the trajectory of the slide groove 11. This cooperation between the locking block 251 and the slide groove 11 can guide and limit the movement of the lifting plate 25, ensuring that the lifting plate 25 moves smoothly in the vertical direction and preventing it from shaking or deviating during the lifting process.
[0030] Specifically, the detection component 7 includes a mounting plate 71, which is slidably connected to the connecting frame 6. A connecting ring 72 is fixedly connected to one end of the mounting plate 71 away from the connecting frame 6. A detection rod 73 is fixedly connected to the inner wall of the connecting ring 72. A load-bearing plate 74 is fixedly connected to the top of the detection rod 73. A detection sensor 75 is provided at the bottom of the outer surface of the detection rod 73.
[0031] The effect achieved by the above components is that the mounting plate 71 is slidably connected to the connecting frame 6, so that the detection component 7 can flexibly adjust its position according to the deformation of the foundation, ensuring that the detection sensor 75 can accurately and stably detect the stress of the foundation under different pressures, and providing data support for accurate detection of the foundation bearing capacity.
[0032] Specifically, the support plate 43 includes a T-shaped plate 431, which is connected to the groove 12. The bottom end of the T-shaped plate 431 is fixedly connected to a fixing pile 432, and the fixing structure 4 is symmetrically distributed on the side of the testing frame 1.
[0033] The aforementioned components achieve the following effects: The T-shaped structure design of the T-plate 431 allows it to slide stably within the groove 12 when connected through it, and prevents displacement during height adjustment. The fixing pile 432, fixed to the bottom end of the T-plate 431, provides significant friction and support after being inserted into the ground, enhancing the stability of the device. The fixing structure 4 is symmetrically distributed on the side of the testing frame 1, simultaneously supporting and fixing the testing frame 1 from both sides, further ensuring the overall stability of the device during testing and preventing tilting or shaking due to uneven force on one side.
[0034] Specifically, a hole 31 is provided in the center of the upper surface of the base plate 3, and a movable wheel 32 is fixedly connected to the bottom of the base plate 3.
[0035] The effects achieved by the above components are as follows: the installation of the movable wheels 32 allows the entire device to be easily moved on the construction site, greatly improving the mobility of the device when changing test points and reducing the cost and difficulty of manual handling. The holes 31 on the base plate 3 provide space for the vertical movement of the test rod 73, ensuring that the test rod 73 can smoothly pass through the base plate 3 during the test and directly contact the foundation to realize the test operation of the foundation bearing capacity.
[0036] Specifically, the detection rod 73 passes through the hole 31 to detect the foundation.
[0037] The aforementioned components achieve the following effect: the detection rod 73 directly contacts the foundation through the hole 31, transmitting the pressure and reaction force of the foundation to the detection sensor 75 and the load-bearing plate 74 in the detection assembly 7. The hole 31 positions and guides the detection rod 73, ensuring that the detection rod 73 is perpendicular to the foundation during detection.
[0038] Working principle: When testing the bearing capacity of the foundation, first push the device and use the moving wheels 32 at the bottom of the base plate 3 to move the device to the position to be tested. After reaching the designated position, rotate the screw 42 in the fixing structure 4 to lower the support plate 43 and insert the fixing pile 432 into the ground to stabilize the device.
[0039] Next, the motor 22 in the lifting device 2 is started. The motor 22 drives the roller 23 to rotate, and the lifting plate 25 is lowered through the pull rope 26, causing the gravity hammer 5 to press down on the load-bearing plate 74. At the same time, the locking blocks 251 at both ends of the lifting plate 25 slide in the slide groove 11 to ensure that the gravity hammer 5 presses vertically. The mounting plate 71 in the detection assembly 7 slides on the connecting frame 6 to adapt to the deformation of the foundation.
