Description

Technical Field

[0001] This utility model relates to the technical field of bearing capacity testing equipment, and in particular to a bearing capacity testing equipment for concrete pile foundations. Background Technology

[0002] Load-bearing capacity testing equipment technology is a technique that uses specialized instruments and methods to determine the load-bearing capacity and safety performance of engineering structures or materials under stress conditions.

[0003] According to CN207469261U, a static load testing device for pile foundations includes a first fixed plate with a telescopic clamping device on the upper right side. The device involves a pressing plate that compresses a pressure plate, applying pressure to the pile foundation as the pressure plate moves downwards. However, the aforementioned document describes a method where the pile foundation is positioned using the first clamping plate and the telescopic clamping device. This application of additional lateral pressure to the pile foundation affects its natural stress state, leading to distorted bearing capacity test data. Furthermore, the clamped portion cannot be tested due to pressure interference, failing to accurately reflect the bearing capacity or deformation characteristics of that section, resulting in incomplete data and interfering with test results. Additionally, the pressure applied by the pressure plate can cause unbalanced stress on the pile foundation, leading to bending or tilting, thus affecting the accuracy of the test data.

Detailed Implementation

[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] Reference Figures 1-4 The concrete pile foundation bearing capacity testing equipment includes a main body and a concrete pile foundation 18. The main body consists of a workbench 1, support legs, and a controller.

[0024] The workbench 1 is fixedly equipped with a mounting frame 19 and two telescopic rods 2 that are electrically connected to the controller. The telescopic rods 2 are used to adjust the position of the moving frame 3 to adapt to the bearing capacity testing of concrete pile foundations 18 of different lengths.

[0025] A movable frame 3 is fixedly installed at the output end of the telescopic rod 2, and two support rods extending into the workbench 1 are fixedly installed on the movable frame 3. The support rods are used to support the movable frame 3, improve the stability of the movable frame 3 when it moves under the drive of the telescopic rod 2, and prevent the movable frame 3 from deviating when it is subjected to force.

[0026] A detector 20 for testing the bearing capacity of the concrete pile foundation 18 is fixedly installed on the mounting frame 19.

[0027] The movable frame 3 is vertically installed at both ends of the workbench 1, and the support rod is horizontally installed on both sides of the telescopic rod 2. The workbench 1 has guide holes corresponding to the support rods. The guide holes guide the movement of the support rods and ensure that the movable frame 3 moves smoothly. The support frame 13 and the mounting frame 19 are concave structures.

[0028] The movable frame 3 is equipped with a positioning structure for positioning the concrete pile body 18. The positioning structure drives the lead screw 5 through the motor 10, which causes the nut 6 to drive the connecting rod 9 to deflect, so that the arc-shaped positioning plate 8 moves along the positioning frame 21 to apply uniform pressure to the inner wall of the concrete pile body 18, ensuring the stability of the concrete pile body 18 during testing, avoiding additional stress interference from rigid clamping, and ensuring the accuracy of test data.

[0029] The positioning structure includes a limiting frame 4 fixedly installed on the movable frame 3, and four circumferentially distributed positioning frames 21 fixedly installed on the limiting frame 4. The positioning frames 21 provide guidance for the slider 7 to prevent the slider 7 from deviating during the movement, and ensure the precise positioning of the positioning plate 8 on the concrete pile body 18. A screw rod 5 that passes through the limiting frame 4 is rotatably installed on the movable frame 3.

[0030] A motor 10 is fixedly installed on the movable frame 3, which is connected to the lead screw 5 and electrically connected to the controller. The motor 10 drives the positioning plate 8 to move through the nut 6 and the connecting rod 9, thereby positioning the concrete pile body 18. The lead screw 5 is slidably fitted with a matching nut 6.

[0031] The positioning frame 21 is slidably fitted with a slider 7, and a positioning plate 8 is fixedly installed on the slider 7 to position the inner wall of the concrete pile body 18. Two connecting rods 9 are installed between the positioning plate 8 and the nut 6 via pins.

[0032] The limiting frame 4 is horizontally positioned on one side of the movable frame 3, and the lead screw 5 is horizontally positioned and extends to one side outside the limiting frame 4.

[0033] The positioning frame 21 has a limiting hole corresponding to the slider 7. The limiting hole cooperates with the I-shaped slider 7 to guide the slider 7 to slide and prevent the slider 7 from deviating during movement.

[0034] The slider 7 has an I-shaped structure, and the positioning plate 8 is horizontally positioned on one side of the slider 7. The positioning plate 8 is an arc-shaped structure that adapts to the inner wall of the concrete pile body 18. The positioning plate 8 increases the contact area with the inner wall of the concrete pile body 18, making the positioning pressure more uniform, improving the stability of positioning the concrete pile body 18, preventing excessive local pressure from damaging the concrete pile body 18, and ensuring the accuracy of the test.

[0035] The workbench 1 is equipped with a support frame 13 for supporting the concrete pile foundation 18 via a movable component. The movable component drives the support frame 13 to move via a gear 15 and a rack 17 meshing with a motor 2 16. The position of the support for the concrete pile foundation 18 can be flexibly adjusted according to the needs of the inspection operation to ensure the reliability of the inspection operation.

[0036] The movable component includes a T-slot formed on the worktable 1, and a movable block 11 extending to the top of the worktable 1 is placed in the T-slot. The movable block 11 cooperates with the T-slot of the worktable 1 to prevent the displacement frame 12 and the support frame 13 from shifting during movement.

[0037] A displacement frame 12, which is integrally connected to the support frame 13, is fixedly installed on the movable block 11. A rotating rod 14 is rotatably installed inside the displacement frame 12. A second motor 16, which is connected to the rotating rod 14 and electrically connected to the controller, is fixedly installed on the displacement frame 12. When the second motor 16 is working, it drives the rotating rod 14 to rotate. Through the meshing transmission of the gear 15 and the rack 17, it drives the support frame 13 to move, thereby realizing the flexible adjustment of the support position of the concrete pile foundation 18.

[0038] A gear 15 is fixedly installed on the rotating rod 14, and a rack 17 that meshes with the gear 15 is fixedly installed on the worktable 1.

[0039] The moving block 11 has a T-shaped structure. The rotating rod 14 and the gear 15 are horizontally arranged and extend to the outside of the displacement frame 12. The rack 17 is horizontally arranged below the gear 15.

[0040] It should be noted that the specific models and specifications of the controller, motor 10, motor 216, and detector 20 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation methods use existing technology in this field, so they will not be elaborated here.

[0041] The functional principle of this utility model can be explained through the following operation methods:

[0042] When it is necessary to perform bearing capacity testing on the concrete pile foundation 18;

[0043] The controller sends an extension command to the telescopic rod 2, and the telescopic rod 2 pushes the moving frame 3 to move, placing the concrete pile body 18 on the support frame 13 accordingly;

[0044] The controller sends a shortening command to the telescopic rod 2, causing the limit frame 4 to drive the positioning plate 8 to extend into the inner ring of the concrete pile body 18;

[0045] When the positioning frame 21 is close to the side wall of the concrete pile body 18, the controller sends a stop command to the telescopic rod 2;

[0046] The controller sends a start command to motor 10, which drives the lead screw 5 to rotate. The lead screw 5 drives the nut 6 to move. The nut 6 drives the connecting rod 9 to deflect around the pin seat. The deflection of the connecting rod 9 generates a position difference, which drives the slider 7 to move along the limiting hole of the positioning frame 21. The slider 7 drives the positioning plate 8 to apply pressure to the inner wall of the concrete pile body 18.

[0047] When the positioning plate 8 is in close contact with the inner wall of the concrete pile body 18, the controller sends a stop command to the motor 10 to achieve stable positioning of the concrete pile body 18.

[0048] When it is necessary to adjust the position of the support frame 13 to support the designated part of the concrete pile body 18;

[0049] The controller sends a start command to motor 16, which drives the rotating rod 14 to rotate. The rotating rod 14 drives the gear 15 to rotate. The gear 15 meshes with the rack 17 to drive the displacement frame 12 and the support frame 13 to move along the worktable 1.

[0050] After the support frame 13 moves to the designated position where the concrete pile body 18 needs to be supported, the controller sends a stop command to the motor 16, and the support frame 13 provides stable support for the concrete pile body 18.

[0051] The controller sends a start command to the detector 20 to perform a bearing capacity test on the concrete pile foundation 18.

[0052] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
