Description

Technical Field

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

[0002] In engineering testing, sampling equipment is often used to collect soil samples to obtain representative soil samples for comprehensive and accurate analysis of physical, chemical, and mechanical properties, providing crucial data support for engineering design, construction, and subsequent safety assessments.

[0003] Existing technologies, such as the utility model with publication number CN219996549U, relate to a surveying device for subway engineering surveying and research, belonging to the field of surveying equipment technology. It mainly solves the problem that sampling can only be performed at the roadbed location, while sampling soil from both sides is inconvenient. The proposed technical solution includes a support component with a movable plate. On the other side of the support component is a driving component that moves the movable plate up and down. A sampling component for drilling is located at the bottom of the movable plate. An adjustment component for adjusting the drilling position of the sampling component is installed at the top of the movable plate. The adjustment component includes an adjustment plate rotatably connected to the movable plate via a rotating shaft. This utility model, through the adjustment component, drives the sampling component to rotate. During sampling, the position of the sampling component can be adjusted according to actual needs, allowing the device to not only drill and sample at the foundation where the device is placed but also to sample soil at other heights, ensuring convenient and efficient sampling during surveying and solving the problem of only being able to sample at the roadbed location while sampling soil from both sides is inconvenient.

[0004] In daily work, it has been found that with existing sampling devices, once a sampling is completed, if a second sampling is to be carried out, the used sampling container must first be replaced, and then a new blank sampling container must be installed on the device before the device can be restarted for the second sampling. The entire operation process not only consumes a lot of time and energy, but also greatly reduces the overall work efficiency, bringing many inconveniences and troubles to soil sampling work in engineering testing. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing sampling equipment in which it is inconvenient to use, and to propose a sampling device for engineering testing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sampling device for engineering testing, comprising a base plate, a bracket fixedly connected to the surface of the base plate, wheels provided on the lower surface of the base plate, a sampling device provided on the surface of the base plate, the sampling device including a rotating frame rotatably connected to the surface of the base plate, four sliding grooves formed on the surface of the rotating frame, and connecting sleeves slidably connected to the inner walls of the sliding grooves, sampling cylinders inserted into the inner walls of each of the four connecting sleeves, a connecting part provided between the connecting sleeve and the sampling cylinder, a spring provided between the rotating frame and the sliding grooves on the surface of the connecting sleeve, and the surface of the connecting sleeve being fixedly connected... There are two auxiliary blocks. A cylinder is fixedly connected to the surface of the bracket. A control ring is fixedly connected to the output end of the cylinder. A through hole is opened on the surface of the base plate for the sampling cylinder to pass through. Collection components are provided on both sides of the base plate.

[0020] Specifically, the sampling device 4 includes a rotating frame 41 rotatably connected to the surface of the base plate 1. The surface of the rotating frame 41 is provided with four sliding grooves 413, and the inner wall of the sliding grooves 413 is slidably connected with connecting sleeves 45.

Collection components 46 are provided on both sides of the base plate 1.

[0021] In this embodiment: When sampling, the rotating frame 41 is rotated, which drives the connecting sleeve 45 and the sampling cylinder 44 to rotate. After rotating to a certain position, the control ring 410 is located between the connecting sleeve 45 and the auxiliary block 49. At this time, the cylinder 43 can drive the connecting sleeve 45 and the sampling cylinder 44 to move, thereby realizing the sampling operation. After sampling, the connecting sleeve 45 and the sampling cylinder 44 are reset. The rotating frame 41 is rotated again, and the next set of sampling cylinders 44 can be used for sampling, improving the overall ease of use.

[0022] Specifically, the spring 47 is located in the inner wall of the sliding groove 413 on the surface of the rotating frame 41, and the two ends of the spring 47 are fixedly connected to the connecting sleeve 45 and the inner wall of the sliding groove 413 on the surface of the rotating frame 41, respectively.

[0023] In this embodiment, the spring 47 can provide thrust to the connecting sleeve 45 and the sampling cylinder 44 to ensure stability.

[0024] Specifically, the connecting part 48 includes a rod 481 that is inserted into the inner wall of the connecting sleeve 45. The sampling cylinder 44 has a through hole 484 on its surface. The rod 481 is inserted into the inner wall of the through hole 484. When connecting the connecting sleeve 45 and the sampling cylinder 44, the rod 481 is simply inserted into the through hole 484 on the surfaces of the connecting sleeve 45 and the sampling cylinder 44 to achieve the connection operation.

[0025] Specifically, a threaded head 483 is fixedly connected to the surface of the insertion rod 481, and a threaded sleeve 482 is fixedly connected to the surface of the connecting sleeve 45. The threaded head 483 is threadedly connected to the inner wall of the threaded sleeve 482.

[0026] In this embodiment: after the insertion rod 481 is inserted into the through hole 484 on the surface of the connecting sleeve 45 and the sampling cylinder 44, the insertion rod 481 can be rotated to connect the threaded head 483 with the threaded sleeve 482, thereby improving the stability of the insertion rod 481.

[0027] Specifically, a motor 42 is fixedly connected to the surface of the bracket 2, and the output end of the motor 42 passes through the bracket 2 and is fixedly connected to the surface of the rotating frame 41.

[0032] Working principle: During sampling, the sampling cylinder 44 is first inserted into the connecting sleeve 45. Then, the insertion rod 481 is inserted into the inner wall of the connecting sleeve 45 and the sampling cylinder 44. After being inserted to a certain position, the insertion rod 481 is rotated, and the threaded head 483 on the surface of the insertion rod 481 is threadedly connected to the threaded sleeve 482 to achieve a positioning effect. Then, the motor 42 is turned on, and the motor 42 drives the rotating frame 41 to move. After rotating to a certain position, the control ring 410 can be located between the connecting sleeve 45 and the auxiliary block 49. The cylinder 43 is turned on, and the cylinder 43 drives the connecting sleeve 45 and the sampling cylinder 44 to move through the control ring 410. The spring 47 is stressed, and the sampling cylinder 44... 4. After passing through the perforation on the surface of the base plate 1, soil samples can be taken. During sampling, the marker block 412 can be used in conjunction with the scale 411 to achieve precise depth sampling. After sampling, the cylinder 43, in conjunction with the control ring 410, drives the connecting sleeve 45 and the sampling cylinder 44 to reset. When sampling again, the motor 42 is turned on, and the motor 42 drives the rotating frame 41 to move. After rotating to a certain position, another set of sampling cylinders 44 is located below the cylinder 43. At this time, the control ring 410 is located between the connecting sleeve 45 and the auxiliary block 49, and the sampling operation can be performed. After subsequent sampling is completed, the sampling cylinder 44 can be removed and placed in the collection box 461 for collection.
