Description

Technical Field

[0001] This utility model relates to the field of foundation testing, and in particular to a prefabricated foundation testing auxiliary support structure that is easy to disassemble and assemble. Background Technology

[0002] With social development, engineering construction projects are increasing. As the foundation of engineering structures, the stability of the foundation directly affects the safety and service life of the entire project. Foundation testing is an indispensable key link in engineering construction. By comprehensively testing the bearing capacity, deformation characteristics, and integrity of the foundation, potential problems can be identified in time and reinforcement measures can be taken to ensure the quality of the project. Among them, foundation slope testing is particularly important. To achieve accurate testing of foundation slopes, radar monitoring devices are widely used. They can monitor the internal structure and soil distribution of foundation slopes by transmitting and receiving radar waves and analyze potential hidden dangers.

[0003] Existing radar monitoring devices often suffer from fixed or difficult-to-adjust angles in their support structures. The terrain of the foundation slope is usually quite complex, with varying slope gradients and surface flatness. Furthermore, during the detection process, the detection angle of the radar monitoring device needs to be flexibly adjusted according to the location and depth of the target and changes in the on-site environment to ensure that the radar waves can accurately cover the target area and obtain clear and complete detection data. If the angle cannot be fine-tuned, when the target is located at different heights or inclinations on the slope, the radar monitoring device may not be able to maintain the optimal detection angle with the target area, resulting in weakened detection signals, data distortion, or the existence of detection blind spots. Utility Model Content

[0004] In view of this, the present invention provides a prefabricated foundation detection auxiliary support structure that is easy to disassemble and assemble. The main technical problem to be solved is that the angle of the existing radar monitoring device support structure is fixed or difficult to fine adjust, resulting in low detection accuracy and poor efficiency.

[0005] To achieve the above objectives, this utility model provides a prefabricated foundation testing auxiliary support structure that is easy to disassemble and assemble, including a support frame, a support base movably mounted at the bottom of the support frame, a connecting shaft threaded inside the support base, three support rods movably mounted at the bottom of the connecting shaft, an mounting plate movably mounted at the top of the support frame, one end of the mounting plate being connected to the top of the support frame via a movable shaft, a radar monitoring device being bolted to the top of the mounting plate, a rotating assembly being installed between the support frame and the support base, and an adjusting assembly being installed between the support frame and the mounting plate;

[0006] The adjustment assembly includes a lead screw, a movable block, an ear plate, and a connecting rod. The lead screw is rotatably mounted on the top of the support frame, the movable block is threaded to the outer wall of the lead screw, the ear plate is fixedly connected to the bottom of the mounting plate, and one end of the connecting rod is rotatably connected to the movable block, while the other end is rotatably connected to the ear plate. Rotating the lead screw moves the movable block, which in turn pushes the ear plate and the mounting plate to rotate around a movable axis via the connecting rod, thus achieving fine-tuning of the radar monitoring device's angle.

[0007] The preferred technical solution of this utility model is as follows: the support base is semi-circular, and the rotating assembly includes a worm and a worm wheel. The worm is rotatably mounted on the bottom of the support frame, and the worm wheel is disposed on the outer wall of the support base, with the worm and worm wheel meshing with each other. Rotating the worm and worm wheel meshing drives the support frame to rotate relative to the support base, thereby realizing the horizontal rotation adjustment of the radar monitoring device.

[0008] The preferred technical solution of this utility model is as follows: Each support rod includes an outer rod, a telescopic rod, and a locking pin. The outer rod is movably connected to the bottom of the outer wall of the connecting shaft. The telescopic rod is slidably installed inside the outer rod. An installation groove is formed inside the portion of the telescopic rod embedded in the outer rod. A spring is fixedly installed inside the installation groove. The locking pin is embedded in the installation groove, and its inner wall is fixedly connected to the spring. When the spring is compressed, the locking pin is completely placed in the installation groove and extends out of the corresponding locking hole as the telescopic rod slides to the corresponding locking hole under the action of the spring. The telescopic rod slides inside the outer rod, and the locking pin engages with different locking holes under the action of the spring, realizing the adjustment of the support rod length to adapt to different terrain heights.

[0009] The preferred technical solution of this utility model is as follows: an arc-shaped groove is formed at the bottom of the support frame, and an arc-shaped connecting block is fixedly connected to the top of the support base. The arc-shaped connecting block is movably installed inside the arc-shaped groove. The arc-shaped connecting block slides within the arc-shaped groove, providing guidance and connection for the rotation of the support frame relative to the support base, ensuring rotational stability.

[0010] The preferred technical solution of this utility model is as follows: a first cross groove is formed on the outer wall of the worm gear, and a second cross groove is formed on the outer wall of the lead screw. The first and second cross grooves facilitate the rotation of the worm gear and lead screw using a cross screwdriver, improving the convenience of adjustment operations.

[0011] The preferred technical solution of this utility model is as follows: a pointed foot is fixedly connected to the bottom of the telescopic rod. The pointed foot can be inserted into the ground to enhance the friction between the support rod and the ground, improve the overall stability of the support structure, and prevent slippage.

[0012] This utility model has at least the following beneficial effects:

[0013] (1) By setting an adjustment component, when it is necessary to fine-tune the tilt angle of the radar monitoring device, a cross screwdriver is inserted into the second cross groove to rotate the lead screw. The lead screw drives the moving block connected to the outer wall thread to slide along the top of the support frame. The moving block pushes the ear plate through the connecting rod. The ear plate drives the mounting plate to rotate around the movable shaft connected to the support frame, thereby changing the tilt angle of the radar monitoring device at the top of the mounting plate. This realizes the function of fine-tuning the radar monitoring device after installation, ensuring that the device can maintain the best angle with the detection target and improving the accuracy and integrity of the detection data.

[0014] (2) By setting up a rotating component, when it is necessary to adjust the horizontal detection direction of the radar monitoring device, a cross screwdriver is inserted into the first cross groove to rotate the worm. The worm meshes with the worm wheel teeth on the outer wall of the support base, causing the support frame to rotate relative to the support base. At the same time, the arc-shaped connecting block slides in the arc-shaped groove to provide guiding support, thus realizing the horizontal rotation adjustment function of the radar monitoring device after installation, enabling it to flexibly cover the detection area in different directions, reduce the detection blind zone, and improve the detection efficiency.

[0015] (3) By setting up support rods, according to the undulations of the foundation slope, press the locking pin to compress the spring and withdraw it from the lock hole, pull the telescopic rod to slide to a suitable length in the outer rod, and after releasing the locking pin, the spring pushes the locking pin into the corresponding lock hole to fix the length of the support rod. The three support rods can be adjusted separately, and with the bottom pointed foot inserted into the ground, stable support is achieved. This realizes the function of installing the radar monitoring device in any terrain, ensuring that the device remains stable in complex terrain and providing a reliable foundation for detection work.

[0024] The embodiment provides a prefabricated foundation testing auxiliary support structure that is easy to disassemble and assemble, such as... Figures 1 to 5As shown, the support structure includes a support frame 1, a support base 2, and a mounting plate 5. The support frame 1 serves as the main frame of the entire support structure, connecting the support base 2 and the mounting plate 5. The support base 2 is movably mounted on the bottom of the support frame 1, providing a rotational support foundation for the support frame 1. A connecting shaft 3 is threaded into the internal part of the support base 2, connecting the support base 2 and the support rods 4. Three support rods 4 are movably mounted on the bottom of the connecting shaft 3, forming a triangular support structure to enhance overall stability. The mounting plate 5 is movably mounted on the top of the support frame 1, used to mount and fix the radar monitoring device 6. The top of the mounting plate 5 is bolted to the radar monitoring device 6, which is used to detect the foundation slope. The bolted connection facilitates the disassembly and installation of the radar monitoring device 6. A rotating assembly 7 is installed between the support frame 1 and the support base 2, allowing for horizontal rotation adjustment of the support frame 1 relative to the support base 2. An adjustment assembly 8 is installed between the support frame 1 and the mounting plate 5, allowing for fine adjustment of the tilt angle of the mounting plate 5.

[0025] In the embodiments, such as Figure 2 As shown, the adjusting assembly 8 includes a lead screw 801, a moving block 802, an ear plate 803, and a connecting rod 804. The lead screw 801 is rotatably mounted on the top of the support frame 1 and can rotate freely on the top of the support frame 1 to provide power to the moving block 802. The moving block 802 is threadedly connected to the outer wall of the lead screw 801. When the lead screw 801 rotates, the moving block 802 moves axially along the lead screw 801 through threaded transmission. The ear plate 803 is fixedly connected to the bottom of the mounting plate 5. The ear plate 803 is used to connect the connecting rod 804 and the mounting plate 5 and transmit the thrust of the connecting rod 804 to the mounting plate 5. The connecting rod 804 is movably mounted between the moving block 802 and the ear plate 803 and can rotate between the moving block 802 and the ear plate 803, converting the linear motion of the moving block 802 into the rotational motion of the ear plate 803.

[0026] In the embodiments, such as Figure 3As shown, the rotating component 7 includes a worm 701 and a worm gear 702. The worm 701 is rotatably mounted on the bottom of the support frame 1 and can rotate at the bottom of the support frame 1, serving as the power input component for rotation adjustment. The support base 2 is semi-circular, and the worm gear 702 is disposed on the outer wall of the support base 2. The semi-circular structure is adapted to the worm gear 702 of the rotating component 7, facilitating smooth rotation. One end of the mounting plate 5 is connected to the top of the support frame 1 via a movable shaft, which allows the mounting plate 5 to rotate around the top of the support frame 1, providing a fulcrum for angle adjustment. The worm gear 702 cooperates with the worm 701 to achieve speed reduction transmission and direction change. The worm 701 and the worm gear 702 mesh with each other, and the rotation of the worm 701 drives the relative movement of the worm gear 702 and the support base 2, thereby realizing the rotation of the support frame 1. The outer wall of the worm gear 701 has a first cross groove 705, which facilitates the rotation of the worm gear 701 using a Phillips screwdriver. The outer wall of the lead screw 801 has a second cross groove 805, which also facilitates the rotation of the lead screw 801 using a Phillips screwdriver, improving the convenience of adjustment operations. The bottom of the support frame 1 has an arc-shaped groove 703, which provides a sliding track for the arc-shaped connecting block 704. The top of the support base 2 is fixedly connected to the arc-shaped connecting block 704. The arc-shaped connecting block 704 cooperates with the arc-shaped groove 703 to enhance the stability of the support frame 1 during rotation. The arc-shaped connecting block 704 is movably installed inside the arc-shaped groove 703 to ensure that the support frame 1 can rotate smoothly relative to the support base 2.

[0027] In the embodiments, such as Figure 4 and Figure 5As shown, the support rod 4 includes an outer rod 401, a telescopic rod 402, a mounting groove 403, a locking pin 404, a spring 405, and a locking hole 406. Three outer rods 401 are movably installed on the bottom of the outer wall of the connecting shaft 3. The outer rods 401 provide installation and sliding space for the telescopic rods 402. The telescopic rods 402 are slidably installed inside the outer rods 401. The telescopic rods 402 can extend and retract within the outer rods 401 to adjust the overall length of the support rod 4. The mounting groove 403 is provided at the part of the telescopic rod 402 that is embedded in the outer rod 401. The mounting groove 403 provides installation space for the locking pin 404 and the spring 405. In the space, a locking pin 404 is slidably installed inside the mounting groove 403. The locking pin 404 is used to insert into the lock hole 406 to fix the position of the telescopic rod 402. A spring 405 is fixedly installed inside the mounting groove 403. The spring 405 provides elastic force to the locking pin 404, making it tightly locked into the lock hole 406. The spring 405 and the locking pin 404 are fixedly installed inside each other. The outer wall of the outer rod 401 has a lock hole 406. Different positions of the lock hole 406 correspond to different telescopic lengths. The locking pin 404 is installed inside the lock hole 406 to achieve relative fixation between the telescopic rod 402 and the outer rod 401. A pointed foot 407 is fixedly connected to the bottom of the telescopic rod 402. The pointed foot 407 can be inserted into the soil or rock crevices to increase the friction between the support rod 4 and the ground, prevent the support structure from sliding during the testing process, and improve the overall stability.

[0028] The working process of this utility model is as follows: First, the support structure is assembled. The connecting shaft 3 is threaded into the inside of the support base 2. Then, the outer rods 401 of the three support rods 4 are movably installed at the bottom of the connecting shaft 3. The length of each support rod 4 is adjusted according to the terrain of the foundation slope. Pressing the locking pin 404 compresses it into the mounting groove 403 of the telescopic rod 402. Pulling the telescopic rod 402 allows it to slide within the outer rod 401, thereby adjusting the length of the support rod 4. When the overall length of the support rod 4 matches the ground height, the locking pin 404 moves to the corresponding locking hole 406. Under the action of the spring 405, it automatically springs open and engages with the corresponding locking hole 406, fixing the relative position of the telescopic rod 402 and the outer rod 401. The pointed feet 407 at the bottom of the three support rods 4 are inserted into the ground to form a stable triangular support, ensuring the entire support structure is placed stably.

[0029] Next, the radar monitoring device 6 is installed on the top of the mounting plate 5 using bolts. If it is necessary to adjust the horizontal detection direction of the radar monitoring device 6, a cross screwdriver is inserted into the first cross groove 705 on the outer wall of the worm 701 and rotated. The worm 701 meshes with the worm gear teeth 702 on the outer wall of the support base 2, causing the support frame 1 to rotate relative to the support base 2. At this time, the arc-shaped connecting block 704 at the top of the support base 2 slides in the arc-shaped groove 703 at the bottom of the support frame 1, providing guidance and support for the rotation until the radar monitoring device 6 is aligned with the required horizontal detection direction.

[0030] If it is necessary to fine-tune the tilt angle of the radar monitoring device 6 to adapt to the slope, use a cross screwdriver to insert into the second cross groove 805 on the outer wall of the lead screw 801 and rotate it. The lead screw 801 rotates on the top of the support frame 1, causing the moving block 802 connected to its outer wall to slide along the axial direction of the lead screw 801. The moving block 802 pushes the ear plate 803 through the connecting rod 804. The ear plate 803 causes the mounting plate 5 to rotate around its movable axis connected to the support frame 1. The radar monitoring device 6 on the top of the mounting plate 5 rotates synchronously with the mounting plate 5 to achieve fine-tuning of the tilt angle until the optimal detection angle is reached.

[0031] After the inspection is completed, each component can be disassembled by reversing the operation, which facilitates transportation and storage, and realizes the convenient disassembly and assembly function of the prefabricated structure.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
