Description

Technical Field

[0001] The present invention relates to the field of engineering detection technology, and more specifically to a sampling device for geotechnical engineering detection. Background Art

[0002] Engineering testing is an important task to ensure the safety of construction projects that have been built, are under construction, and will be built. It tests the foundations, building materials, construction technology, and building structures related to the buildings during the entire construction process. At present, the sampling equipment cannot exclude large rocks in the rock and soil; rock and soil is a general term for any rock and soil that makes up the earth's crust from the perspective of engineering construction; rock and soil can be subdivided into five categories: hard (hard rock), sub-hard (soft rock), weakly connected, loosely unconnected, and with special composition, structure, state, and properties. China is accustomed to calling the first two categories rock and the last three categories soil, collectively referred to as "rock and soil".

[0003] In this regard, China's patent application number: CN114441223B discloses a geotechnical engineering detection sampling device, including a sampling cannula, the bottom of the sampling cannula is fixedly connected with a displacement cone, the two sides of the outside of the sampling cannula and close to the top are symmetrically fixedly connected with a rotating support rod, the surface of the outside of the sampling cannula is evenly provided with a driving thread, the bottom of the outside of the displacement cone is fixedly connected with an insertion circular groove, the bottom of the insertion circular groove is evenly provided with a stone removal mechanism, the middle position of the inside of the sampling cannula is slidably connected with a compacting plate, the surface of the compacting plate is evenly provided with sieve holes, the surface of the inside of the sampling cannula is evenly fixedly connected with a resistance-increasing cone plate, and the inner surface of the resistance-increasing cone plate is in corresponding contact with the outer side of the compacting plate. The present invention relates to the field of engineering detection technology. The geotechnical engineering detection sampling device removes the rock and soil inside the bottom of the device to the outside, avoids blockage caused by stones accumulating under the device, and improves the sampling accuracy.

[0004] However, in actual use, the sampling cannot continue downwards after the insertion groove touches the harder rock when moving downwards, which will also cause the sampling to be interrupted. The above-mentioned mechanism can only remove the rocks near the insertion groove, and cannot remove the stones at the bottom completely and evenly. It has certain limitations in removal. Therefore, it has become an urgent problem to be solved to perfect and improve the above-mentioned problems. Summary of the invention

[0005] The object of the present invention is to provide a sampling device for geotechnical engineering detection, so as to solve the problem raised in the above-mentioned background technology that after the insertion circular groove touches the harder rock when moving downward, it is impossible to continue sampling downward, which will also cause the sampling to be interrupted. The above-mentioned mechanism can only remove the rocks near the insertion circular groove, and cannot remove the stones at the bottom completely and evenly, and has certain limitations in removal.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0007] A sampling device for geotechnical engineering detection, comprising a sampling tube, a limiting plate is fixedly connected to one side of the surface of the sampling tube, a mounting cone is arranged on the lower surface of the sampling tube, a stabilizing ring is fixedly connected to the outer surface of the mounting cone, a first motor is arranged on the top surface of the stabilizing ring, and an output end of the first motor passes through the interior of the stabilizing ring and is mounted with a first drill rod;

[0008] A first mounting ring is fixedly connected to the outer surface of the first drill pipe, a stabilizing block is fixedly connected to the left surface of the first mounting ring, and a cleaning rod is fixedly connected to the left surface of the stabilizing block;

[0009] The inner side wall of the stabilizing block is fixedly connected to a second motor, a first limiting roller is provided at an output end of the second motor, a first rotating disk is fixedly connected to an end of the first limiting roller away from the second motor, a second rotating disk is fixedly connected to an outer surface of the first rotating disk, a moving frame is installed on an outer surface of the second rotating disk, a first interference rod is fixedly connected to the lower end of the moving frame, and a second interference rod is fixedly connected to the upper end of the moving frame.

[0010] Preferably, a limiting frame is provided on one side of the surface of the moving frame, the limiting frame is installed on the inner bottom wall of the stabilizing block, and the first abutting rod passes through the lower surface of the stabilizing block.

[0011] Preferably, two groups of the limiting frames are provided, and the installation positions of the two groups of the limiting frames are symmetrical to each other.

[0012] Preferably, a belt body is provided on the outer surface of the first limiting roller, a second limiting roller is provided on the inner wall of the belt body, a second rotating disk is fixedly connected to the front surface of the second limiting roller, and the second rotating disk has the same structure as the first rotating disk.

[0013] Preferably, a second drill rod is provided on the lower surface of the stabilizing ring, a second mounting ring is provided on the outer surface of the second drill rod, and the second mounting ring has the same structure as the stabilizing block.

[0014] Preferably, an electric push rod is fixedly connected to the top surface of the inner wall of the sampling tube, a servo motor is arranged on the lower surface of the electric push rod, and a drilling rod is arranged at the output end of the servo motor.

[0015] Preferably, a limiting plate is provided on one side of the surface of the drilling rod, and a limiting ring is fixedly connected to the top surface of the limiting plate.

[0016] Preferably, a tight ring and a fixing sleeve are sequentially arranged on the other side of the surface of the drilling rod from top to bottom, and a rubber strip is evenly and fixedly connected to the outer surface of the tight ring.

[0017] Preferably, a stabilizing disk is movably mounted on the outer surface of the fixing sleeve, a sampling tube is inserted and mounted inside the stabilizing disk, and a groove is formed at the lower end of the sampling tube.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The sampling tube is installed on the rock and soil as a whole. After the harder rock and soil are crushed, the first motor is started, and then the first motor drives the first drill rod to rotate forward and reversely, so as to drive the stabilizing block to rotate forward and backward. The design of the trapezoidal block can prevent the rock and soil from adhering to the front and rear surfaces of the stabilizing block. Then, the rotation of the stabilizing block drives the cleaning rod to rotate at the crushed rock, so that the cleaning rod can repeatedly beat the stone after it hits the stone, so as to move the stone to the edge of the pit;

[0020] 2. When the stabilizing block moves, the second motor inside drives the first limiting roller to rotate, and then the first limiting roller drives the first rotating disk to rotate. When the first rotating disk drives the second rotating disk to rotate, the moving frame moves back and forth up and down. The movement of the moving frame can be limited by the design of the limiting frame to ensure that the movement trajectory of the moving frame is consistent, so that the first resistance rod and the second resistance rod can be pushed to extend and retract up and down. When the first resistance rod and the second resistance rod are exposed on the surface of the stabilizing block, the stones in the rock and soil can be slapped by the first resistance rod and the second resistance rod, so that the stones are moved to the edge of the pit, and the rocks and stones inside the rock and soil can be removed well.

[0021] 3. When sampling, the electric push rod drives the servo motor and the drilling rod downward as a whole. At this time, the sampling tube will continue to move downward, so that the rock and soil will enter the interior of the sampling tube. At the same time, when the drilling rod rotates, the tight ring and the rubber strip will also rotate, so that the outer surface of the sampling tube can be slapped. At this time, the rock and soil on the upper end of the sampling tube will move downward, and the sampling tube will be inserted into the inside of the rock and soil, so that more rock and soil can be sampled, and the rock and soil will be more compact, ensuring the sampling effect of the rock and soil;

[0022] 4. By starting the electric push rod, the drill rod can be driven to move downward as a whole, so that when the drill rod hits the harder rock and soil, the servo motor is started, and the servo motor drives the drill rod to rotate, thereby breaking the rock and soil. Then, the design of the limiting plate and limiting ring can avoid the splash of stones generated when the rock and soil are broken. BRIEF DESCRIPTION OF THE DRAWINGS
