Detailed Implementation

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-4This utility model provides a static load test platform for foundation piles, including a support frame 1, a support frame 2, a top plate 3, a U-shaped frame 4, and a counterweight 5. The support frame 2 is fixedly installed on the upper part of the support frame 1, the top plate 3 is fixedly installed on the top of the support frame 2, and a stabilizing frame 301 is fixedly connected to both sides of the top of the top plate 3. The U-shaped frame 4 is stably installed on the upper part of the top plate 3 through the stabilizing frame 301. The counterweight 5 is installed on the U-shaped frame 4. A connecting device 8 is provided at the bottom of the U-shaped frame 4 and is installed on the top plate 3. A foundation pile 7 is installed below the connecting device 8, and a movable support mechanism 6 is provided on the support frame 1.

[0024] The movable support mechanism 6 includes a movable component 61 and a support component 62. The movable component 61 is disposed on the support frame 1 for moving and adjusting the device, and the support component 62 is disposed inside the support frame 1 for supporting and adjusting the device.

[0025] The movable support mechanism 6 facilitates the movement of the entire device and provides stable support and positioning, thereby enabling stable static load testing of the foundation pile 7 and improving its stability in use. The movable component 61 also improves the installation efficiency of the device.

[0026] The connecting device 8 includes a connecting frame 801, which is installed through the top plate 3. A gravity sensor 802 is installed inside the connecting frame 801 and located below the U-shaped frame 4. A connector 803 is fixedly connected inside the connecting frame 801 and connected to the gravity sensor 802. A support rod 805 is fixedly connected to the bottom of the gravity sensor 802. A display 804 is fixedly installed on the front side of the connecting frame 801 and connected to the gravity sensor 802.

[0027] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the movable component 61 includes an electric telescopic rod 611, which is fixedly installed on the front and rear sides of the top of the support frame 1. A slider 612 is fixedly connected to the bottom of the electric telescopic rod 611. A groove 613 is provided in the support frame 1 corresponding to the slider 612. The slider 612 slides in the support frame 1 by matching the groove 613. A moving wheel 614 is fixedly installed at the bottom of the slider 612. The moving wheel 614 is provided through the slider 612 at the bottom of the support frame 1.

[0028] In use, the electric telescopic rod 611 operates, causing the slider 612 to slide within the slide groove 613, which in turn pushes the moving wheel 614 downward to support the device, thus facilitating the overall movement of the device. Furthermore, the operation of the electric telescopic rod 611 retracts the moving wheel 614 into the slide groove 613, thereby allowing the bottom of the support frame 1 to be supported by the ground, thus supporting the entire device.

[0029] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the support component 62 includes a mounting groove 621, which is opened inside the support frame 1. A movable plate 622 is slidably arranged inside the mounting groove 621. Two movable plates 622 are symmetrically arranged on the left and right sides of the mounting groove 621. A connecting block 623 is fixedly connected to one side of the movable plate 622. The connecting block 623 is provided with a limit groove 624 on the support frame 1 and communicates with the mounting groove 621. A support plate 625 is fixedly connected to one side of the connecting block 623. The support plate 625 is set outside the support frame 1 through the connecting block 623. The bottom horizontal height of the support plate 625 is flush with the bottom horizontal height of the support frame 1. A bidirectional threaded rod 626 is threadedly connected to the movable plate 622. The bidirectional threaded rod 626 is rotatably installed on the support frame 1 through a bearing. A motor 627 is fixedly connected to one end of the bidirectional threaded rod 626. The motor 627 is fixedly installed on the outer surface of the support frame 1.

[0030] In use, the motor 627 operates, causing the bidirectional threaded rod 626 to rotate, which in turn causes the two movable plates 622 on it to move towards each other. The movable plates 622 slide within the mounting groove 621, thereby pushing the connecting block 623 to slide within the limiting groove 624. This pushes the support plate 625 out of the support frame 1. By pushing the support plate 625 out, the support area of ​​the support frame 1 is increased, thereby ensuring the stability of the device support and improving the stability of the experimental work.

[0031] This solution has the following working process: When this device is in use, the electric telescopic rod 611 operates, causing the slider 612 to slide within the groove 613, thereby pushing the moving wheel 614 downwards to support the device. This facilitates the overall movement of the device, allowing it to be moved onto the foundation pile 7 for a static load test. The support rod 805 is positioned at the top of the foundation pile 7, working in conjunction with the gravity sensor 802 and connector 803 to conduct the test. At this time, the electric telescopic rod 611 retracts the moving wheel 614 into the groove 613, allowing the bottom of the support frame 1 to be supported by the ground, thus providing overall support for the device. The support is provided, and the motor 627 operates to rotate the bidirectional threaded rod 626, thereby causing the two movable plates 622 on it to move towards each other. The movable plates 622 slide in the mounting groove 621, which in turn pushes the connecting block 623 to slide in the limiting groove 624, thereby pushing the support plate 625 out of the support frame 1. By pushing out the support plate 625, the support area of ​​the support frame 1 is increased, thereby ensuring the stability of the device support and improving the stability of the experimental work. By placing a counterweight 5 on the upper part of the U-shaped frame 4, a static load test is conducted on the foundation pile 7, and the stability of the U-shaped frame 4 is improved by the stabilizing frame 301.

[0032] In summary: The movable support mechanism 6 facilitates the movement of the entire device and provides stable support and positioning, thereby enabling stable static load testing of the foundation pile 7 and improving its operational stability. Furthermore, the movable component 61 enhances the installation efficiency of the device.
