Description

Technical Field

[0001] This utility model belongs to the field of clay sampling technology, and in particular relates to a sampling device for silty clay in extremely cold regions. Background Technology

[0002] The construction of heavy-duty industrial plant floors under backfill conditions in frigid regions faces severe technical challenges. Frequent freeze-thaw cycles in the frigid climate significantly reduce the stability of the backfill soil and the bearing capacity of the foundation. Combined with the heavy-duty requirements of industrial plants, this greatly increases the difficulty of floor construction, easily leading to quality problems such as ground settlement and cracking. These factors not only affect the service life and safety of the plant but also increase maintenance costs. Considering the regional characteristics of seasonally frozen soil areas, silty clay was selected, and its properties were studied. The main influencing factors included moisture content, dry density, freezing temperature, and the number of freeze-thaw cycles. Single-factor and orthogonal experiments were conducted under different conditions and levels in both open and closed systems. Regression analysis was performed using the single-factor experiments to determine the relationship between the thaw settlement coefficient of silty clay and moisture content, dry density, cold end temperature, and the number of freeze-thaw cycles. Through orthogonal experiments, the primary and secondary relationships of the influence of various factors on the seasonal thaw settlement coefficient of frozen soil were determined. For this type of soil, dynamic compaction and vibro-compaction stone pile treatment are proposed to improve the compaction of the foundation soil and the bearing capacity of the foundation, reduce uneven settlement of the foundation, and eliminate quality problems such as collapsibility of the foundation. This will provide a basis for projects using collapsible silt and silty clay as foundations of the same type. Sampling devices will be used when taking soil samples.

[0003] A technical problem with existing technologies is that when some sampling devices drill for silty clay in frigid regions, the downward movement of the rotary drill bit is guided and limited by the stationary position of the moving frame. However, vibrations occur during the actual operation of the rotary drill bit, which may cause the sampling frame to tilt, requiring additional force from the operators to stabilize it. Therefore, a sampling device for silty clay in frigid regions is needed. This device can improve stability by adding a diagonal bracing structure to the side of the sampling frame, allowing the bracing to support the ground. This creates a stable triangular structure between the ground, the bracing, and the sampling frame, thereby improving the stability of the sampling frame during use. Utility Model Content

[0004] The purpose of this invention is to provide a sampling device for silty clay in frigid regions. The technical problem to be solved is that the rotary drill bit will vibrate during operation, which may cause the sampling frame to tilt. This requires the staff to apply additional force to fix the sampling frame, affecting the sampling efficiency and sampling effect.

[0005] It has the advantage of improving the stability of the sampling device's position when in use by adding a diagonal brace structure to the side of the sampling frame, so that the diagonal brace can be supported by the ground, and a triangular stable structure is formed between the ground, the diagonal brace and the sampling frame, thereby solving the problems mentioned in the background art.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A sampling device for silty clay in extremely cold regions includes a sampling frame body. A lifting orifice plate is slidably installed on the surface of the sampling frame body. A drilling component is installed on the surface of the lifting orifice plate. Universal rollers are installed at the bottom of the sampling frame body. A side-hanging U-shaped plate is fixedly connected to the surface of the sampling frame body by bolts. An electric telescopic rod is fixedly installed on the inner wall of the side-hanging U-shaped plate. A sleeve is fixedly connected to the output shaft of the electric telescopic rod. A horizontal shaft is rotatably connected to the inner wall of the sleeve. A support plate one is rotatably connected to the bottom of the side-hanging U-shaped plate through a rotating shaft. A connecting support rod is rotatably connected between the support plate one and the horizontal shaft. A support plate two is welded to the bottom of the support plate one. A block-shaped slide rail is fixedly connected to the bottom of the support plate two. A sliding strip block is slidably connected to the inner wall of the block-shaped slide rail. A bolt rod is threadedly connected to the surface of the sliding strip block.

[0007] The sampling device for silty clay in frigid regions described above is further characterized by the following: a spring is fitted on the surface of the sampling frame, and the spring is a stainless steel spring.

[0008] The present invention provides a sampling device for silty clay in frigid regions as described above, further comprising: a rolling ball embedded in the surface of the sleeve, the rolling ball being in contact with the inner wall of the horizontal shaft.

[0009] The present invention provides a sampling device for silty clay in frigid regions as described above, further comprising: the end of the bolt rod penetrating the slide block and extending into the interior of the block slide rail; and the bottom of the block slide rail having an insertion hole adapted to the bolt rod.

[0010] The present invention provides a sampling device for silty clay in frigid regions as described above, further comprising: a limiting groove adapted to the horizontal shaft is provided on the surface of the side-mounted U-shaped plate.

[0011] The present invention provides a sampling device for silty clay in frigid regions as described above, further comprising: a hand handle welded to the surface of the lifting orifice plate.

[0012] The sampling device for silty clay in frigid regions described above is further characterized in that: the first support plate, the side-hanging U-shaped plate, the block slide rail, the second support plate, the connecting support rod, and the slide block are all stainless steel components.

[0013] This invention utilizes an electric telescopic rod to move the casing downwards, causing the casing to apply force to the connecting support rod via a horizontal shaft. This causes the connecting support rod to rotate via support plate one, which in turn rotates support plate two. Support plate two then rotates via a block-shaped slide rail and bolt rod, causing the sliding block to rotate and abut against the ground. This achieves the goal of improving the positional stability of the sampling device by adding a diagonal brace structure to the side of the sampling frame, allowing the diagonal brace to support the ground and forming a stable triangular structure between the ground, the diagonal brace, and the sampling frame. This invention also solves the technical problem that vibrations generated during the operation of rotary drilling bits can cause the sampling frame to tilt, thus affecting sampling efficiency and results.

[0019] Figure 1-4 This invention illustrates a sampling device for silty clay in frigid regions, comprising a sampling frame 1, a lifting orifice plate 2 slidably mounted on the surface of the sampling frame 1, a drilling assembly 3 mounted on the surface of the lifting orifice plate 2, and universal rollers 4 mounted on the bottom of the sampling frame 1. The universal rollers 4 are preferably nylon universal rollers with brakes, so that they can be locked and positioned during sampling to prevent the device from moving. For example, the spring 5 has a stiffness coefficient in the range of 20-40 N / mm, and the elastic coefficient can be adjusted according to the sampling depth and drilling resistance. A spring 5, made of stainless steel, is fitted onto the surface of the sampling frame 1. The spring 5 buffers and supports the descent of the drilling assembly 3 and the lifting plate 2 on the surface of the sampling frame 1, preventing damage caused by direct impact between the lifting plate 2 and the sampling frame 1. A side-hanging U-shaped plate 6 is fixedly connected to the surface of the sampling frame 1 by bolts. An electric telescopic rod 7 is fixedly installed on the inner wall of the side-hanging U-shaped plate 6. The electric telescopic rod 7 can be a linear push rod motor with an output stroke of 100-200 mm and a rated thrust greater than 500 N to ensure the driving force of the device when sampling in the frozen soil layer. The output shaft of the electric telescopic rod 7 is fixedly connected to a sleeve 8. A horizontal shaft 9 is rotatably connected to the inner wall of the sleeve 8. A ball bearing 10 is embedded in the surface of the sleeve 8 and is in contact with the inner wall of the horizontal shaft 9. The ball bearing 10 provides padding protection between the sleeve 8 and the horizontal shaft 9, avoiding direct contact and excessive wear, thereby reducing wear and extending the service life of both. The bottom of the side-mounted U-shaped plate 6 is rotatably connected to a support plate 11 via a pivot. A connecting support rod 12 is rotatably connected to the support plate 11 and the horizontal shaft 9. A support plate 2 13 is welded to the bottom of the support plate 11. A block slide rail 14 is fixedly connected to the bottom of the support plate 2 13. A slide block 15 is slidably connected to the inner wall of the block slide rail 14. A bolt rod 16 is threadedly connected to the surface of the slide block 15.

[0020] Figure 1-4 This invention illustrates an embodiment of a sampling device for silty clay in frigid regions, comprising a sampling frame 1. A lifting orifice plate 2 is slidably mounted on the surface of the sampling frame 1. A drilling assembly 3 is mounted on the surface of the lifting orifice plate 2. Universal rollers 4 are mounted on the bottom of the sampling frame 1. A side-hanging U-shaped plate 6 is bolted to the surface of the sampling frame 1. An electric telescopic rod 7 is fixedly mounted on the inner wall of the side-hanging U-shaped plate 6. A sleeve 8 is fixedly connected to the output shaft of the electric telescopic rod 7. A horizontal shaft 9 is rotatably connected to the inner wall of the sleeve 8. A support plate 11 is rotatably connected to the bottom of the side-hanging U-shaped plate 6 via a rotating shaft. A connecting support rod 12 is rotatably connected between the support plate 11 and the horizontal shaft 9. A second support plate 13 is welded to the bottom of the first support plate 11. A block-shaped slide rail 1 is fixedly connected to the bottom of the second support plate 13. 4. A slider block 15 is slidably connected to the inner wall of the block slide rail 14. A bolt rod 16 is threadedly connected to the surface of the slider block 15. The end of the bolt rod 16 passes through the slider block 15 and extends into the interior of the block slide rail 14. The bottom of the block slide rail 14 is provided with an insertion hole that matches the bolt rod 16. The surface of the side-mounted U-shaped plate 6 is provided with a limiting groove 17 that matches the horizontal shaft rod 9. A hand handle 18 is welded to the surface of the lifting hole plate 2. The hand handle 18 increases the surface area of ​​the lifting hole plate 2, preventing the hand from slipping when the lifting hole plate 2 is moved vertically by hand, thereby improving the grip. The support plate 11, the side-mounted U-shaped plate 6, the block slide rail 14, the support plate 2 13, the connecting rod 12, and the slider block 15 are all stainless steel components.

[0021] Working principle: When using this utility model, the user pushes the sampling frame 1 to move the universal rollers 4 on the ground, then places the sampling frame 1 vertically, and then moves the sleeve 8 downward through the electric telescopic rod 7. This causes the sleeve 8 to exert force on the connecting support rod 12 through the movement of the horizontal shaft rod 9 in the limiting slide groove 17. As a result, the connecting support rod 12 causes the support plate 11 to drive the support plate 2 13 to flip. Then, the support plate 2 13 drives the sliding block 15 to flip and abut against the ground through the block slide rail 14 and the bolt rod 16. The bolt rod 16 controls the sliding block 15. The sliding within the inner wall of the block slide rail 14 is adjusted and locked, which changes the effective length of the extended slide block 15, improving the applicability of the slide block 15 to support uneven ground. Then, by holding the hand handle 18, the lifting hole plate 2 is moved vertically, so that the lifting hole plate 2 drives the drilling component 3 to drill the soil. This achieves the goal of adding a diagonal brace structure to the side of the sampling frame, so that the diagonal brace can be supported by the ground, and a triangular stable structure is formed between the ground, the diagonal brace and the sampling frame, thereby improving the stability of the sampling frame position when the sampling device is in use.

[0022] In summary, this silty clay sampling device for frigid regions uses an electric telescopic rod 7 to move the sleeve 8 downwards. This causes the sleeve 8 to exert force on the connecting support rod 12 via the horizontal shaft 9. Consequently, the connecting support rod 12 causes the support plate 11 to rotate the support plate 13. Then, the support plate 13 rotates the sliding block 15 via the block slide rail 14 and bolt rod 16, causing it to abut against the ground. This achieves the goal of improving the positional stability of the sampling frame during use by adding a diagonal bracing structure to the side of the sampling frame, allowing the diagonal bracing to support the ground. This creates a triangular stable structure between the ground, the diagonal bracing, and the sampling frame, thereby improving the positional stability of the sampling frame during use.

[0023] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
