Description

Technical Field

[0001] The utility model relates to the technical field of ground pressure bearing test, in particular to a ground pressure bearing device. Background Art

[0002] Ground pressure test is a professional evaluation method used to determine the bearing capacity and stability of the ground under different loads. This test is crucial to the design and construction of infrastructure such as buildings, roads, and bridges. By simulating actual load conditions, testers can accurately evaluate the compressive strength and deformation characteristics of the ground, thereby ensuring the safety and stability of the structure. The results of the ground pressure test can provide a scientific basis for engineering design and construction, avoid potential safety hazards, and ensure the smooth progress of the project.

[0003] The existing Chinese patent with announcement number CN210315699U discloses a pressure-bearing device for foundation bearing capacity detection, including two transversely arranged fixing bars and two longitudinally arranged supporting bars, each fixing bar is provided with grooves with the same number as the supporting bars, each supporting bar is fixed in the corresponding groove of the fixing bar, and the lower surfaces of the fixing bar and the supporting bar are in the same plane; the fixing bar and the supporting bar cooperate with each other to form a tic-tac-toe arrangement, a square accommodating cavity is provided therein, and a connecting piece is provided in the accommodating cavity to form a whole with the fixing bar and the supporting bar and to evenly distribute the force received by the connecting piece to the fixing bar and the supporting bar.

[0004] Although the above scheme can avoid the occurrence of warping at both ends of the pressure plate and improve the accuracy of the detection data, the pressure-bearing device is relatively fixed, which limits its applicability in different test scenarios. When testing is required for different sizes of ground or different pressure requirements, pressure plates of different sizes need to be replaced, which increases the complexity and time cost of the testing process. Therefore, it does not meet the existing needs. For this reason, we propose a ground pressure-bearing device. Utility Model Content

[0005] The utility model aims to provide a ground pressure bearing device to solve the problem that the ground pressure bearing device mentioned in the background technology has a fixed structure and is not easy to change the pressure bearing area.

[0006] To achieve the above object, the utility model provides the following technical solution: a ground pressure bearing device, comprising a connecting block, first support blocks are arranged on both sides and front and rear sides of the outside of the connecting block, second support blocks are arranged on the outside of the first support blocks, third support blocks are arranged on the outside of the second support blocks, and fourth support blocks are arranged on the outside of the third support blocks;

[0007] It also includes a slide groove, which is opened at the four corners of the outer wall of the connecting block, the four corners of the outer sides of the first support block, the second support block and the third support block, and the inner sides of the first support block, the second support block, the third support block and the fourth support block are welded with four slide rods, one end of each of the slide rods extends to the inside of the slide groove, and each of the slide rods is slidably matched with the slide groove;

[0008] It also includes a storage groove, which is opened on the outer wall of the connecting block, the outside of the first support block, the second support block and the third support block, and there are two storage grooves. A first limit block is arranged inside the storage groove, and the first limit block is connected to the storage groove through a first rotating shaft.

[0009] Preferably, a second limiting block is arranged inside the first limiting block, and the second limiting block is connected to the first limiting block via a second rotating shaft.

[0010] Preferably, an open groove is formed on the outer side of each of the first limiting blocks.

[0011] Preferably, four return springs equidistantly distributed in a ring shape are arranged outside the slide rod.

[0012] Preferably, a sliding block is welded to one end of the sliding rod located inside the sliding groove, and the sliding block is slidably matched with the sliding groove.

[0013] Preferably, two limiting grooves are provided on the inner sides of the first supporting block, the second supporting block, the third supporting block and the fourth supporting block, and the limiting grooves are adapted to the first limiting block.

[0014] Preferably, the connecting block, the first supporting block, the second supporting block, the third supporting block and the fourth supporting block are in contact with each other.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model provides the first support block, the second support block, the third support block and the fourth support block on both sides and the front and rear ends of the connecting block. When conducting a ground pressure test, the operator can pull the fourth support block as required, and the slide bar will slide inside the slide groove, so that the fourth support block can be separated from the third support block. The movement of the four fourth support blocks can increase the pressure-bearing area. At the same time, the operator can move the first support block, the second support block and the third support block, and can further adjust the fourth support block. The operator can move these support blocks according to the specific requirements of the test scene, thereby realizing the adjustment of the overall structure of the pressure-bearing device. This all-round adjustment can adapt to tests of different sizes of ground and different pressure requirements, greatly improving its applicability in various test scenes.

[0017] 2. The utility model has reset springs arranged at the front, back, top and bottom of the outside of the sliding rod. When the operator adjusts the position of the support block according to the test requirements, the reset spring will be in a compressed or stretched state, storing a certain amount of elastic potential energy. When the test is completed or the device needs to be folded up, the reset spring will release the stored elastic potential energy, pushing or pulling the support block to move to the initial position. Since the reset springs are arranged at the front, back, top and bottom, the support block can be subjected to uniform force in multiple directions, thereby achieving fast, smooth and accurate reset. This automatic reset design not only simplifies the operating process and improves test efficiency, but also effectively avoids device damage or data errors caused by improper manual reset.

[0018] 3. The utility model provides receiving grooves on the outer walls of the connecting block, the first support block, the second support block and the third support block. When the fourth support block is separated from the third support block, the first limit block can be rotated so that one end of the first limit block is inserted into the limit groove on the inner side of the fourth support block, thereby limiting the fourth support block. At the same time, the first limit block can be limited by rotating the second limit block, thereby improving stability. The operator can also limit the first support block, the second support block and the third support block in a similar manner. The fixed limits between these support blocks can not only ensure their stability during the test, but also avoid data errors caused by relative displacement between the support blocks during the adjustment process.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 The utility model provides a technical solution: a ground pressure-bearing device, comprising a connecting block 1, first supporting blocks 2 are arranged on both sides and the front and rear sides of the connecting block 1, second supporting blocks 3 are arranged on the outer sides of the first supporting blocks 2, third supporting blocks 4 are arranged on the outer sides of the second supporting blocks 3, and fourth supporting blocks 5 are arranged on the outer sides of the third supporting blocks 4;

[0027] It also includes a slide groove 7, which is opened at the four corners of the outer wall of the connecting block 1, the four corners of the outer sides of the first support block 2, the second support block 3 and the third support block 4, and the inner sides of the first support block 2, the second support block 3, the third support block 4 and the fourth support block 5 are welded with four slide rods 6, one end of the slide rod 6 extends to the inside of the slide groove 7, and the slide rod 6 is slidably matched with the slide groove 7;

[0028] It also includes a storage groove 10, which is opened on the outer wall of the connecting block 1, the outer side of the first supporting block 2, the second supporting block 3 and the third supporting block 4, and there are two storage grooves 10. A first limit block 11 is arranged inside the storage groove 10, and the first limit block 11 is connected to the storage groove 10 through a first rotating shaft 14.

[0029] When in use, the operator pulls the fourth support block 5, and separates it from the third support block 4 by sliding the slide bar 6 in the slide groove 7. The slide block 8 ensures that the slide bar 6 will not completely fall out of the slide groove 7. The reset spring 9 is stretched when the fourth support block 5 moves, and the fulcrum is increased through the open groove 13. The first rotating shaft 14 is rotated to make the first limit block 11 fit into the limit groove 12, and the second rotating shaft 15 is rotated at the same time to make the second limit block 16 contact the storage groove 10, thereby fixing the position of the fourth support block 5. This design allows the pressure-bearing area to be adjusted in all directions to adapt to different sizes of ground and pressure test requirements.

[0030] See also Figure 4 A second limit block 16 is disposed on the inner side of the first limit block 11. The second limit block 16 is connected to the first limit block 11 through a second rotating shaft 15. The second limit block 16 can firmly support and limit the position of the first limit block 11 to prevent it from accidentally moving or rotating during operation, thereby enhancing the stability and safety of the entire structure.

[0031] See also Figure 3 , Figure 4 and Figure 5 The outer sides of the first limiting blocks 11 are provided with opening grooves 13, which provide a convenient point of force for the operator, making it easier to rotate the first limiting blocks 11, thereby achieving the limiting and unlocking operations on the fourth supporting block 5, thereby improving the convenience and efficiency of the operation;

[0032] See also Figure 4 and Figure 5 , four return springs 9 are arranged outside the slide rod 6 and are evenly spaced. The return springs 9 can provide uniform and stable elastic force to ensure that when the limit is released, the support block can quickly and smoothly return to the initial position. At the same time, the evenly spaced distribution of the four return springs 9 also ensures uniform force transmission, avoiding structural damage or deformation caused by uneven force;

[0033] See also Figure 4 and Figure 5 The sliding block 8 is welded to one end of the sliding rod 6 located inside the sliding groove 7, and the sliding block 8 is slidably matched with the sliding groove 7. The sliding block 8 ensures the stable sliding of the sliding rod 6 in the sliding groove 7, prevents the sliding rod 6 from shaking or tilting during the movement, and ensures the stable movement and positioning accuracy of the support block;

[0034] See also Figure 4 and Figure 5 The inner sides of the first support block 2, the second support block 3, the third support block 4 and the fourth support block 5 are each provided with two limiting grooves 12, and the limiting grooves 12 are all adapted to the first limiting block 11. The adaptability of the limiting grooves 12 to the first limiting block 11 makes the limiting operation more accurate and reliable, ensuring the stable connection and limiting effect between the support blocks;

[0035] Furthermore, the connecting block 1, the first supporting block 2, the second supporting block 3, the third supporting block 4 and the fourth supporting block 5 fit together, and the mutually fitting structural design reduces the gap and friction between the supporting blocks, making storage easier.

[0036] Working principle: when in use, the fourth support block 5 on the outside is pulled, and the fourth support block 5 will drive the sliding rod 6 to move synchronously, so that the sliding rod 6 slides out from the inside of the sliding groove 7, and the setting of the sliding block 8 can prevent the sliding rod 6 from escaping from the inside of the sliding groove 7, so that the fourth support block 5 can be separated from the third support block 4, and the reset spring 9 will be stretched at this time. The operator can increase the force point through the opening groove 13, and rotate the first limit block 11 through the first rotating shaft 14, so that one end of the first limit block 11 is inserted into the inside of the limit groove 12. At the same time, the operator can synchronously rotate the second rotating shaft 15 so that one end of the second limit block 16 can contact the storage groove 10. At this time, the fourth support block 5 can be moved toward the direction of the third support block 4 under the elastic recovery action of the reset spring 9, but due to the support of the first limit block 11, The fourth support block 5 can be limited to fix the position of the fourth support block 5, thereby separating the fourth support block 5 from the third support block 4. The movement of the four fourth support blocks 5 can increase the pressure-bearing area. At the same time, the operator can move the first support block 2, the second support block 3 and the third support block 4, and the fourth support block 5 can be further adjusted. These support blocks can be moved according to the specific requirements of the test scene, thereby realizing the adjustment of the overall structure of the pressure-bearing device. This all-round adjustment capability can adapt to tests of different sizes of ground and different pressure requirements, greatly improving its applicability in various test scenes. At the same time, when the limits of the first limit block 11 and the second limit block 16 are released, the support blocks can be quickly restored under the elastic action of the reset spring 9, making it more convenient to use.
