[0002] In pipeline construction, municipal engineering and foundation pit operations, it is often necessary to sample and analyze the soil layers to assess parameters such as geological conditions and soil bearing capacity.

[0003] Traditional sampling methods rely heavily on manual operation or fixed machinery, which suffers from problems such as inconvenience in movement, limited sampling location, and low operating efficiency. Especially in narrow or uneven pit working environments, the equipment is difficult to adjust its position and height flexibly, and the sampling process lacks effective support, which can easily lead to sampling deviation or equipment instability. Although there are some mobile sampling devices available, they are often single-function and lack auxiliary support and counterweight balance design for the sampling process. They are also difficult to adjust quickly and operate stably under complex working conditions. In addition, sampling equipment and auxiliary tools are usually carried separately, which is inconvenient for on-site storage and management, affecting the continuity and safety of operations.

[0017] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example 1

[0019] Please refer to Figures 1-3. The soil sampling device before deep pipeline foundation pit operation includes a movable plate 1. A bearing seat 2 is fixedly embedded on one side of the movable plate 1. A support frame 3 is movably embedded in the bearing seat 2. A sampler is connected to the upper end of the side wall of the support frame 3. An auxiliary support is installed on one side of the sampler. A counterweight assembly is installed on the upper end of the movable plate 1. Four adjusting movable devices are installed at the four corners of the movable plate 1.

[0020] When sampling the pipeline pit, firstly, adjust the four adjusting devices at the four corners of the moving plate 1 according to the site requirements to make the moving plate 1 horizontal in the working position. Then, move the moving plate 1 to the working position by pushing it. According to the sampling requirements, adjust the sampler on one side of the support frame 3 to place it in the designated position in the pipeline pit. Then, put the counterweight sand into the counterweight assembly to improve the overall structure's anti-overturning ability during sampling and ensure operational safety. Finally, adjust the height of the auxiliary support to make its bottom end fit with the ground on the other side of the pipeline pit to further ensure sampling stability. The support frame 3 is connected to the moving plate 1 through the bearing seat 2, which can achieve horizontal rotation, which is beneficial for the extraction of the sample.

[0021] In the specific implementation process, the sampler includes a sliding frame 4. One side of the sliding frame 4 is fixedly connected to the upper end of the side wall of the support frame 3. A sliding block 5 is movably embedded in the sliding frame 4. A lead screw 6 is movably embedded in the side walls at both ends of the sliding frame 4 through bearings. The lead screw 6 movably passes through the center of the sliding block 5. A sampling winch 7 is installed at the bottom end of the sliding block 5.

[0022] When sampling in the pipeline pit, after the operator has set up the equipment, they first turn the screw 6 in the sliding frame 4. The screw 6 engages with the internal thread of the sliding block 5, changing the position of the sliding block 5 in the sliding frame 4. This aligns the sampling winch 7 with the designated sampling position in the pipeline pit. A storage structure, such as a storage trough or storage box, is installed at the bottom of the sampling winch 7 to hold the soil sample. Since there is a large amount of soil to be sampled in the pipeline pit, the operator enters the pit, excavates the soil sample, places it in the storage structure, and controls the sampling winch 7 by switching it on and off to change the height of the sampling device. This allows for sampling at different heights within the pipeline pit, reducing the labor intensity of manually lifting soil samples.

[0023] Meanwhile, when using other sampling equipment in the pipeline pit, a sampling winch can be used to assist in raising and lowering the soil sampling equipment. For example, if a spiral soil drill or a gasoline-powered sampling drill is needed, these types of equipment are relatively heavy and inconvenient to lower into the pit. When they need to be taken out of the pit, it will be more difficult for the operator. A hanging rope or bracket can be set at the bottom of the sampling winch to temporarily fix the soil sampling equipment and prevent it from falling.

[0024] It should be noted that the technical solution should also include a corresponding power supply structure, which can be powered by a storage battery. The battery should be installed at an appropriate location on the equipment. Additionally, a control switch for the sampling winch 7 should be added so that the power supply structure can supply power to the sampling winch 7 and the control switch. The control switch can then be used to raise and lower the sampling winch.

[0025] In the specific implementation process, the auxiliary support includes a guide frame 8, which is installed on the other side of the sliding frame 4. Two connecting bolts 9 are embedded in the upper wall of the guide frame 8. Four guide sleeves 10 are installed at the four corners of the guide frame 8. Two auxiliary rods 11 are movably embedded in the four guide sleeves 10. Support plates 12 are installed at the bottom of the two auxiliary rods 11. Two positioners are installed between the two auxiliary rods 11 and the four guide sleeves 10.

[0026] During assembly, two connecting bolts 9 are embedded in the guide frame 8 and the sliding frame 4 to fix the guide frame 8 and the sliding frame 4. During the sampling process, by turning the two locators, the two auxiliary rods 11 can move flexibly within the four guide sleeves 10, so that the support plate 12 at their bottom end contacts the ground. Then, the locators are tightened to fix the position of the auxiliary rods 11 and the support plate 12. At the same time, under the connection of the guide frame 8, the overall sampling stability of the sliding frame 4 is ensured. The connecting bolts 9 can realize the quick connection between the guide frame 8 and the sliding frame 4, and also facilitate the quick disassembly of the guide frame 8.

[0027] In the specific implementation process, the two positioners include a number of positioning holes 13, which are evenly opened on the outer wall of the two auxiliary rods 11. Two positioning plates 14 are connected to the outside of the four guide sleeves 10. Two positioning bolts 15 are movably embedded in the two positioning plates 14, and one end of each positioning bolt 15 is movably embedded in one of the two positioning holes 13.

[0028] When locking the auxiliary rod 11, first adjust the auxiliary rod 11 to the specified height within the four guide sleeves 10, so that two of the positioning holes 13 on the side wall of the auxiliary rod 11 correspond to the center of the positioning plate 14. Then, tighten the positioning bolt 15. The center of the positioning plate 14 is machined with an internal thread that matches the positioning bolt 15. When tightening the positioning bolt 15, under the action of the internal thread, the positioning bolt 15 moves towards the auxiliary rod 11 within the positioning plate 14 until one end of the positioning bolt 15 is inserted into the specified positioning hole 13 on the side wall of the auxiliary rod 11, thereby fixing the auxiliary rod 11.

[0029] In the specific implementation process, the counterweight assembly includes a storage box 16, which is fixedly installed at the center of the upper end of the movable plate 1, and a counterweight sand box 17 is installed on the other side of the upper end of the movable plate 1.

[0030] The storage box 16 allows for the storage of sampled soil, and the counterweight sand box 17 can be filled on-site to ensure the sampling stability of the device.

[0031] In the specific implementation process, the four adjusting and moving devices include four mounting sleeves 18, which are fixedly embedded in the four corners of the moving plate 1. Four moving rods 19 are movably embedded in the four mounting sleeves 18. Four moving wheels 20 are installed at the bottom of the four moving rods 19. Eight plug-in plates 21 are installed on both sides of the upper end of the four mounting sleeves 18. Several fixing holes 22 are opened on the side walls of the four moving rods 19. Four pins 23 are movably embedded in the eight plug-in plates 21 and the four moving rods 19.

[0032] When the device is moved, the four moving wheels 20 at the lower ends of the four moving rods 19 contact the ground to ensure the overall stability of the device's movement. The height of the moving rods 19 within the mounting sleeves 18 can be changed by the mounting sleeves 18, allowing independent adjustment of the four moving wheels 20. Finally, the four pins 23 are inserted into the eight plug plates 21 and the designated fixing holes 22 to fix the overall height of the moving rods 19, ensuring the overall stability of the moving wheels 20's movement.

[0033] In the specific implementation process, four reinforcing ribs 24 are installed at the connection position between the sliding frame 4 and the support frame 3.

[0034] This further ensures the overall strength of the sliding frame 4 and the stability of sampling during use.
