Description

Technical Field

[0001] This invention belongs to the field of building foundation pile engineering testing technology, specifically a geological exploration and testing sampling device and method for building foundation pile engineering. Background Technology

[0002] In building foundation pile engineering, geological investigation and testing is a crucial step. The quality and stability of building foundation piles are closely related to the properties of the underground soil layers. Soil layers at different depths may have significant differences in physical properties, chemical properties, and mechanical properties. Sampling devices are key tools for obtaining underground geological information. Therefore, before foundation pile construction, it is necessary to use geological investigation and testing sampling devices to conduct geological exploration of the construction area and to take samples deep underground.

[0003] Existing geological survey and sampling devices for some building foundation pile projects can only be fixed at a specific depth for sampling. To obtain samples at different depths, the device needs to be repeatedly disassembled and adjusted, making it inconvenient to sample soil layers at different depths. The bottom of existing sampling devices is mostly flat, which is time-consuming and laborious to cut through the soil layer. Furthermore, when removing samples from the soil, the bottom of existing geological survey and sampling devices for building foundation pile projects is not sealed, and soil samples are prone to falling out, which cannot guarantee the integrity of the samples. Existing geological survey and sampling devices for building foundation pile projects are not convenient enough for observing and removing samples. They require the samples to be completely removed before they can be observed, which increases the number of operating steps and the risk of sample damage. The process of removing samples is cumbersome and inefficient. Summary of the Invention

[0004] The purpose of this invention is to provide a geological survey and sampling device and method for building foundation pile engineering. A second motor drives a rotating gear to rotate, which in turn drives a connecting rod to rotate, thereby adjusting the rotation of the connecting plate and the cutter. The angle of the cutter's rotation is adjusted. When the cutter is in a vertical position, multiple cutters form a serrated shape at the bottom of the rotating tube. During sampling, an external drive device drives the storage tube, rotating tube, and adjusting mechanism to rotate and move downwards simultaneously, while the cutter rotates, facilitating sampling by the user. When sampling soil samples at different depths is required, the cutter is adjusted to a closed state, and the external drive device drives the storage tube and the rotating... The tube and the closed-state cutter rotate, allowing the soil layer to be rotated to a suitable depth. After the cutter is adjusted to a vertical position, sampling can continue. Simultaneously, when the sample needs to be removed from the soil after sampling, adjusting the cutter to the closed state prevents soil samples from falling out, ensuring sample integrity. The rotation of the tube is regulated by a first motor, and the scale on the surface of the tube allows for easy observation of the sampled soil condition. A preliminary assessment of the soil quality can be made without completely removing the soil. An electric telescopic rod pushes a push plate, causing the rotating tube to slide and loosen the soil inside the storage tube, allowing it to fall into an external storage container. This simplifies the soil sampling process and improves sampling efficiency.

[0005] The technical solution adopted in this invention is as follows: a geological exploration and sampling device for building foundation pile engineering, comprising: a storage tube; a rotating tube, wherein the rotating tube is slidably sleeved on the outer surface of the storage tube; a moving mechanism, wherein the moving mechanism is disposed on the storage tube and the rotating tube and is configured to adjust the position of the rotating tube; and an adjusting mechanism, wherein the adjusting mechanism is disposed on the moving mechanism and is configured to take soil samples.

[0006] The moving mechanism includes a fixed box, a pushing component, and a power component. The fixed box is slidably sleeved on the outer surface of the storage tube, the pushing component is disposed on the storage tube, and the power component is disposed on the fixed box and the rotating tube.

[0007] The pushing component includes an electric telescopic rod, a pushing plate, and multiple limiting plates. One end of the electric telescopic rod is fixedly connected to the lower inner wall of the storage tube. The top of the pushing plate is fixedly connected to the extended end of the electric telescopic rod. One end of each limiting plate is fixedly connected to the outer surface of the pushing plate, and the other end of the limiting plate is rotatably embedded in the inner surface wall of the rotating tube.

[0008] The power component includes a first motor, a fixed gear, and a fixed gear ring. The fixed gear ring is fixedly embedded on the outer surface of the rotating tube. The first motor is fixedly connected to the top of the fixed box. The fixed gear is fixedly sleeved on the output end of the first motor, and the fixed gear and the fixed gear ring mesh with each other.

[0009] The adjustment mechanism includes a mounting box, multiple sets of support components, multiple sets of connecting components, multiple sets of transmission components, and rotating components. The top of the mounting box is fixedly connected to the bottom of the rotating tube. Each set of support components, rotating components, and connecting components is mounted on the mounting box, and each set of transmission components is mounted on the support components and connecting components.

[0010] Each set of support components includes two support plates, two connecting plates, a connecting rod, a cutter, and two distance sensors. The top of each support plate is fixedly connected to the upper inner wall of the mounting box. The two ends of the connecting rod are rotatably connected between the two support plates. Each connecting plate is fixedly sleeved on the outer surface of the connecting rod. The top of the cutter is fixedly connected to one end of the two connecting plates. The outer surfaces of the two distance sensors are respectively fixedly embedded on one side of the outer surface of the cutter.

[0011] The rotating component includes a second motor, a rotating gear, a rotating gear ring, and a transmission conical gear ring. The second motor is fixedly connected to the upper inner wall of the mounting box. The rotating gear is fixedly sleeved on the output end of the second motor. The top end of the transmission conical gear ring is rotatably embedded in the upper inner wall of the mounting box. The rotating gear ring is fixedly connected to the inner surface wall of the transmission conical gear ring, and the rotating gear ring and the rotating gear mesh with each other.

[0012] Each of the connecting components includes a mounting plate and a transmission rod. The bottom of the mounting plate is fixedly connected to the lower inner wall of the mounting box, and one end of the transmission rod rotatably passes through one side of the outer surface of the mounting plate.

[0013] Each set of transmission components includes a fixed bevel gear and two transmission bevel gears. The fixed bevel gear is fixedly sleeved on one end of the transmission rod, and the mounting plate meshes with the transmission bevel gear ring. One of the transmission bevel gears is fixedly sleeved on the other end of the transmission rod, and the other transmission bevel gear is fixedly sleeved on the outer surface of the connecting rod. The two transmission bevel gears mesh with each other.

[0014] A sampling method for a geological survey and sampling device used in building foundation pile engineering includes the following steps:

[0015] Step 1: Soil Sampling: Connect the storage tube via an external drive device. During sampling, the external drive device rotates the storage tube, rotating tube, and adjusting mechanism, causing them to move downwards simultaneously. At this time, multiple cutters are in a closed state. The adjusting mechanism rotates and drills into the ground. Then, the second motor is turned on, driving the rotating gear to rotate. Through the meshing of the rotating gear and the rotating gear ring, the rotating gear ring drives the transmission conical gear ring to rotate. Through the meshing of the transmission conical gear ring and the fixed conical gear, the fixed conical gear drives the transmission rod and one of the transmission conical gears to rotate. Through the meshing of two transmission conical gears, the other transmission conical gear drives the connecting rod to rotate, causing the connecting plate and the cutter to rotate. Adjust the position of the cutter to make it vertical. The external drive device rotates the storage tube, rotating tube, and adjusting mechanism, causing them to move downwards simultaneously. Through the setting of the cutter, the soil enters the rotating tube for storage. Soil samples can be taken from different depths as needed. After sampling, the second motor rotates to adjust the cutter to a closed state. Then, the storage tube and rotating tube are taken out. The bottom of the storage tube and rotating tube can be sealed to prevent soil samples from falling out.

[0016] Step 2: Observe the condition of the sampled soil: Turn on the first motor and adjust the rotation of the rotating tube. Through the meshing of the fixed gear and the fixed gear ring, the fixed gear ring drives the rotating tube to rotate on the outer surface of the storage tube, and the condition of the sampled soil can be observed.

[0017] Step 3: Remove the sampled soil: Adjust the cutter to a vertical position by rotating the second motor, and move the push plate by the electric telescopic rod. The push plate drives the rotating tube to slide on the storage tube, pushing the soil in the storage tube, so that the soil is loosened and falls into the external storage container.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] (1) In this invention, the second motor drives the rotating gear to rotate, and the connecting rod rotates through the transmission, thereby adjusting the rotation of the connecting plate and the cutter. The angle of the cutter rotation is adjusted. When the cutter is adjusted to a vertical state, multiple cutters are serrated at the bottom of the rotating tube. During sampling, the storage tube, rotating tube and adjusting mechanism are rotated and moved downwards by the external driving device, and the cutter rotates, which facilitates sampling by the user. When it is necessary to sample soil samples at different depths, the cutter is adjusted to a closed state by the second motor. After the distance sensor senses that the cutter is closed, the second motor is automatically turned off. The storage tube, rotating tube and the closed cutter are rotated by the external driving device, and the soil layer can be rotated to a suitable depth. Then the cutter is adjusted to a vertical state by the second motor. When a certain distance is sensed between the two distance sensors, the second motor is automatically turned off, and sampling continues. At the same time, when it is necessary to remove the sample from the soil after sampling, the cutter is adjusted to a closed state to prevent the soil sample from falling and to ensure the integrity of the sample.

[0020] (2) In this invention, the rotation of the rotating tube is adjusted by the first motor, and the scale on the surface of the rotating tube is set so that the soil condition can be easily observed. The soil quality can be preliminarily judged without completely removing the soil. The electric telescopic rod pushes the push plate, which drives the rotating tube to slide and loosen the soil in the storage tube into the external storage container, simplifying the soil sampling process and improving the sampling efficiency.

Through the cutter 405, soil enters the rotating tube 2 for storage. Soil samples can be taken from different depths as needed. After sampling, the cutter 405 is adjusted to a closed state by rotating the second motor 407. Then, the storage tube 1 and rotating tube 2 are removed, and their bottoms can be sealed to prevent soil samples from falling out. Step two: Observe the state of the sampled soil: Turn on the first motor 30... 2. Drive the fixed gear 303 to rotate. Through the meshing of the fixed gear 303 and the fixed gear ring 304, the fixed gear ring 304 drives the rotating tube 2 to rotate on the outer surface of the storage tube 1, so that the soil condition of the sample can be observed. Step 3: Take out the sampled soil: Adjust the cutter 405 to a vertical state by rotating the second motor 407. Push the push plate 306 to move by the electric telescopic rod 305. The push plate 306 drives the rotating tube 2 to slide on the storage tube 1, pushing the soil in the storage tube 1, so that the soil is loosened and falls into the external storage container.

The storage tube (1), the rotating tube (2) and the adjustment mechanism (4) are driven to rotate and move downwards simultaneously through the external drive device. Through the setting of the cutter (405), the soil enters the rotating tube (2) through the cutter (405) for storage. Soil samples can be taken at different depths as needed. After sampling, the cutter (405) is adjusted to a closed state by rotating the second motor (407). Then the storage tube (1) and the rotating tube (2) are taken out. The bottom of the storage tube (1) and the rotating tube (2) can be sealed to prevent soil samples from falling out. S2. Observe the soil condition of the sample: Turn on the first motor (302) to drive the fixed gear (303) to rotate. Through the meshing of the fixed gear (303) and the fixed gear ring (304), the fixed gear ring (304) drives the rotating tube (2) to rotate on the outer surface of the storage tube (1), and the soil condition of the sample can be observed. S3. Take out the sampled soil: Adjust the cutter (405) to a vertical position by rotating the second motor (407), and push the push plate (306) to move by the electric telescopic rod (305). The push plate (306) drives the rotating tube (2) to slide on the storage tube (1), pushing the soil in the storage tube (1) to loosen the soil and fall into the external storage container.
