Description

Technical Field

[0001] This utility model relates to the field of foundation testing technology, and in particular to a protective mechanism for a foundation testing device. Background Technology

[0002] Foundation testing refers to the process of testing and analyzing the bearing capacity, stability, and deformation performance of a building's foundation, aiming to ensure the safety and stability of the building. Drilling sampling equipment extracts soil or rock samples from the foundation using drilling technology. These samples are fundamental to analyzing the physical and mechanical properties of the foundation. For example, drilling sampling can reveal the structure and properties of soil layers, as well as the rock and soil characteristics of the bearing stratum, thus providing a scientific basis for foundation design and construction.

[0003] In existing technologies, drilling and sampling processes may generate debris such as mud and gravel. If these debris are not controlled, they may contaminate equipment and construction personnel, and even affect the standardization of subsequent operations. Therefore, we propose a protective mechanism for a foundation testing device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a protective mechanism for a foundation detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A protective mechanism for a foundation testing device includes two inner protective plates hinged together. Two outer protective plates are slidably connected to the outer walls of the two inner protective plates, also hinged together. Ear plates are fixedly connected to the outer walls of both outer protective plates. Sliding holes are formed at the top of each ear plate, and vertical rods are slidably connected to the inner walls of each sliding hole. An arc-shaped plate is fixedly connected to the top of each inner protective plate. Through holes are formed on the outer walls of both ear plates, and bolts are threaded onto the inner walls of each through hole. Two mating blocks are fixedly connected to the outer wall of one outer protective plate, and two mating grooves are formed on the outer wall of the other outer protective plate. The inner walls of the two mating grooves are slidably connected to the outer walls of the two mating blocks, respectively. A locking assembly is provided on the outer walls of the outer protective plates.

[0007] Preferably, the locking assembly includes two hooks. Two I-shaped columns are fixedly connected to the outer wall of one of the outer protective plates. A circular sleeve is rotatably fitted onto the outer wall of each of the two I-shaped columns. One end of each of the two hooks is fixedly connected to the outer wall of the two circular sleeves. Two cylindrical blocks are fixedly connected to the outer wall of the other outer protective plate. Through holes are provided on the outer wall of each of the two cylindrical blocks. By setting the locking assembly, the two outer protective plates are fixed in position to prevent them from moving during use.

[0008] Preferably, both vertical rods have threaded holes at their bottoms, and the inner walls of both threaded holes are threaded with T-shaped posts, which limit the movement distance of the vertical rods.

[0009] Preferably, the tops of the two vertical rods are fixedly connected to the bottoms of the two arc-shaped plates, and the vertical rods are used to assist the two arc-shaped plates and the two inner protective plates in moving up and down.

[0010] Preferably, one end of each of the two bolts is pressed against the outer wall of the two vertical rods, and the vertical rods are fixed to the ear plate by means of the bolts.

[0011] Preferably, the same hydraulic soil sampling drill is placed inside the two inner protective plates.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution, by setting up an inner protective plate, an outer protective plate, vertical rods, T-shaped columns, ear plates, bolts, arc-shaped plates, connecting blocks, I-shaped columns, round sleeves, hooks, columnar blocks, and through holes, can form a vertically retractable enclosure.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1-4 As shown, a protective mechanism for a foundation testing device includes two inner protective plates 1, which are hinged together. Two outer protective plates 2 are slidably connected to the outer walls of the two inner protective plates 1, and are also hinged together. The two outer protective plates 2 and the two inner protective plates 1 form a barrier to prevent mud, gravel, and other debris from splashing. Ear plates 5 are fixedly connected to the outer walls of the two outer protective plates 2. Sliding holes are provided at the top of the two ear plates 5. Vertical rods 3 are slidably connected to the inner walls of the two sliding holes. Threaded holes are provided at the bottom of the two vertical rods 3. T-shaped columns 4 are threadedly connected to the inner walls of the two threaded holes. By rotating the two T-shaped columns 4, they can slide out from the inner walls of the two threaded holes, allowing the two inner protective plates 1 to slide out from inside the two outer protective plates 2.

[0022] The top of each of the two inner protective plates 1 is fixedly connected to an arc-shaped plate 7. The top of each of the two vertical rods 3 is fixedly connected to the bottom of the two arc-shaped plates 7 respectively. The arc-shaped plates 7 are designed for easy hand-holding, allowing the two inner protective plates 1 to be moved up and down. The outer walls of the two ear plates 5 are provided with through holes. The inner walls of the two through holes are threaded with bolts 6. One end of each bolt 6 is pressed against the outer wall of the two vertical rods 3 respectively.

[0023] Two docking blocks 9 are fixedly connected to the outer wall of one of the outer protective plates 2, and two docking grooves are opened on the outer wall of the other outer protective plate 2. The inner walls of the two docking grooves are slidably connected to the outer walls of the two docking blocks 9 respectively. The docking blocks 9 and the docking grooves can assist the two outer protective plates 2 to rotate and dock, which facilitates the subsequent use of the two hooks 12 and the two through holes 14. The same hydraulic soil sampling drill 8 (hpd60) is placed inside the two inner protective plates 1. The hydraulic soil sampling drill 8 (hpd60) works on the principle of liquid pressure. When a liquid with a certain pressure is applied from the outside enters the sampler, the liquid will fill the inner cavity of the hollow drill bit (sampling cylinder), thereby forming hydrostatic pressure. When the hollow drill bit (sampling cylinder) enters the soil, the hydrostatic pressure of the liquid will resist the resistance of the soil and push the hollow drill bit (sampling cylinder) into the soil to collect soil samples.

[0024] The outer wall of the outer protective plate 2 is provided with a locking assembly, which includes two hooks 12. Two I-shaped columns 10 are fixedly connected to the outer wall of one of the outer protective plates 2. The outer walls of the two I-shaped columns 10 are rotatably fitted with round sleeves 11. One end of the two hooks 12 is fixedly connected to the outer walls of the two round sleeves 11 respectively. The two round sleeves 11 rotate through the two I-shaped columns 10 and drive the two hooks 12 to move.

[0025] Two cylindrical blocks 13 are fixedly connected to the outer wall of another outer protective plate 2. The outer walls of the two cylindrical blocks 13 are provided with through holes 14. The inner walls of the two through holes 14 are slidably connected to the outer walls of the two hooks 12 respectively. When the two hooks 12 are located in the through holes 14, due to the rotation angle and their own weight downward, the hooks 12 cannot slide out of the through holes 14 when they are not subjected to upward external force.

[0026] Working principle: When drilling and sampling the foundation soil, the hydraulic soil sampling drill 8 is moved to the sampling point. Then, the two outer protective plates 2 and the two inner protective plates 1 are moved to the vicinity of the drill bit position of the hydraulic soil sampling drill 8. The two hooks 12 are rotated so that one end slides out of the through hole 14 in the two cylindrical blocks 13, releasing the position fixation of the two outer protective plates 2. The two outer protective plates 2 and the two inner protective plates 1 are rotated to move outward, unfolding them and sliding them to the drill bit position of the hydraulic soil sampling drill 8. The two outer protective plates 2 and the two inner protective plates 1 are rotated again to bring them closer together and are repositioned by the locking assembly, forming a barrier around the drill bit of the hydraulic soil sampling drill 8. The two bolts 6 can be rotated as needed so that one end no longer presses against the outer wall of the two vertical rods 3, releasing the position fixation of the two vertical rods 3. The two arc plates 7 drive the two inner protective plates 1 to move upward, increasing the upward barrier range. The two vertical rods 3 move upward in a straight line through the two ear plates 5, ensuring that the two inner protective plates 1 do not rotate.

[0027] All standard parts used in this utility model can be purchased from the market. Irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.

Furthermore, the structure and principle of the components known to those skilled in the art can be learned by those skilled in the art through technical manuals or conventional experimental methods.
