Description

Technical Field

[0001] The invention relates to the technical field of civil engineering construction, in particular to a sampling and measuring device for civil engineering construction and a measuring method thereof. Background Art

[0002] Civil engineering is a general term for the science and technology of building various engineering facilities. Any engineering facility is inevitably affected by natural or human factors (usually called loads). In order to ensure safety, various engineering facilities must have the ability to resist the combined effects of the above-mentioned various loads;

[0003] Generally, when the compression resistance of the sampling device is measured during the construction process, the sampling is basically completed. The soil is made to fall into a container through the squeezing device in the sampling device, and then the pressing device with a measuring sensor is used to press and measure the top of the soil sample. When the soil falls into the container, due to the gravity of the soil itself, the soil is prone to collide with the container during the falling process.

[0016] Furthermore, a method for using a sampling and measuring device for civil engineering construction is provided, the sampling and measuring device for civil engineering construction comprising the following steps:

[0017] S1: First, connect the device to the construction vehicle through the top of the main body, and place the device at the location where sampling is required by the construction vehicle. Then, start the hydraulic rod to drive the sampling tube to descend. When the sampling tube descends, it will drive the sampling port and insert it into the soil. After the soil is collected, place the bag inside the working box, and then drive the sampling tube to rise by the hydraulic rod;

[0018] S2: Then start the electric push rod 2, which will push the sampling tube when working, so that the sampling tube moves to the top of the fixed mechanism, and then the sampling tube is driven up again by the hydraulic rod, so that the push rod squeezes the bottom plate, and then multiple push rods push the soil, so that the soil falls into the bag inside the working box;

[0019] S3: Then start the measuring sensor and electric push rod 1. When the electric push rod 1 descends, it will push the measuring sensor and the chassis to squeeze the soil. When the chassis squeezes the soil, the chassis will perform real-time measurement and apply pressure to the soil sample block until the soil sample block collapses. At this moment, the measuring sensor will record the maximum resistance value of the soil sample block collapse and complete the measurement.

[0020] The present invention has the following beneficial effects:

[0021] 1. In the present invention, when soil falls into the working box, the motor is started. When the motor is working, the gears on the output end of the motor are driven to rotate. At the same time, when the motor is working, the T-shaped rod is driven through the cross plate to rotate the T-shaped rod inside the special-shaped disk. When the T-shaped rod rotates to the protrusion on the special-shaped disk, the T-shaped rod moves in the cross plate toward the soil, and then rotates with the rotation of the cross plate. When the T-shaped rod moves forward, the moving T-shaped rod brings the fixed frame, so that the fixed frame drives the swing plate to fit the soil. The surface of the bag, and then when the T-bar rotates with the cross plate, the roller at the bottom of the T-bar will contact the inner wall of the special-shaped disk and rotate. When the roller rotates, the rotating roller will pass the special-shaped bar, so that the special-shaped bar drives the swing frame to reciprocate inside the fixed frame. At this time, the reciprocating swing frame will squeeze the soil through the swing plate, which can ensure that the soil reaches a certain density before the compression test, while maintaining the integrity of the soil, avoiding bumps when the soil falls, resulting in incompleteness, and affecting the accuracy of compaction measurement.

[0022] 2. In the present invention, when the swing frame reciprocates inside the fixed frame, the reciprocating swing frame will drive the rotating shaft to rotate synchronously. When the swing frame drives the rotating shaft to rotate, the rotating rotating shaft will squeeze the inclined rod. After the inclined rod is squeezed, it will press against the rotating shaft to rotate the rotating shaft. When the rotating shaft rotates, it will push the two-way tooth plate through the moving rod to make the two-way tooth plate rotate around the connecting rod. When the connecting rod rotates, the rotating connecting rod will drive the rack to make the rack slide inside the swing frame. Since there are four racks and two of them are in a group, when the connecting rod rotates, the two groups of racks will slide one after the other. When the two sets of racks are sliding, the racks will drive the swing plate to rotate in contact with the surface of the soil. At this time, the swing plate rotating on the soil surface will squeeze the soil during rotation, so that the soil can cover a wider area when the swing plate squeezes the soil, ensuring that the soil is evenly compacted, avoiding unevenness when the swing frame drives the swing plate to squeeze the soil. At the same time, when the swing plate rotates, it can also reduce the situation where the swing plate is under excessive pressure when squeezing the soil, avoiding the situation where the soil is broken before measurement due to excessive pressure and uneven squeezing, affecting the measurement results.

[0023] 3. In the present invention, when the rack is rotated by the bidirectional tooth plate, the rack will slide inside the swing frame. When the rack slides, the sliding rack will drive the elastic plate to move through the fixed rod. Since the elastic plate is elastic, the elastic plate will shake when the elastic plate moves. When the elastic plate shakes, the shaking elastic plate will drive the sliding plate through the movable plate, so that the sliding plate slides inside the limiting plate 2. When the sliding plate slides, the sliding sliding plate will drive the spring block to shake. When the spring block shakes, it will periodically collide with the side wall of the swing plate. At this time, the collision force generated by the spring block on the side wall of the swing plate can further destroy the structure between the soil particles, making them more closely arranged, thereby increasing the density of the soil.

[0024] 4. In the present invention, when the moving rod pushes the two-way toothed plate to rotate back and forth, the rotating two-way toothed plate will drive the connecting rod to rotate, and the connecting rod will drive the air outlet frame to rotate through the cylindrical rod when rotating. When the air outlet frame rotates, the rotating air outlet frame will drive the piston plate to squeeze the telescopic plate in the rotation direction of the cylindrical rod. After being squeezed, the telescopic plate will slide in the air outlet frame against the piston plate. When the piston plate slides, it will squeeze the gas inside the air outlet frame. After being squeezed, the gas in the air outlet frame will pass through the front end of the air outlet frame and spray into between the two air collecting bags, causing the air collecting bags to expand slightly. At this time, when the swing plate is pushed by the rack to deflect, the deflected swing plate will pull the C-shaped rod through the limit rod to rotate the C-shaped rod. When the C-shaped rod rotates, the rotating C-shaped rod will drive the roller to slide from the opening of the air collecting bag. When the roller slides, the roller will squeeze the opening of the air collecting bag, so that part of the gas inside the air collecting bag is concentrated at the rear end of the air collecting bag, and the rear end of the air collecting bag is expanded. After the air collecting bag expands, a buffer layer will be formed between the swing plate and the spring block, which can reduce the impact force of the spring block when the spring block hits the swing plate, so as to avoid the soil becoming loose due to excessive impact force when the spring block hits the side wall of the swing plate, and to avoid the soil collapse before measurement, which will cause the measuring sensor to be unable to measure the soil and affect the measuring effect of the measuring sensor.

When the chassis 104 squeezes the soil, the chassis 104 will perform real-time measurement and apply pressure to the soil sample block until the soil sample block collapses. At this moment, the measuring sensor 103 will record the maximum resistance value of the collapse of the soil sample block to complete the measurement.

[0054] When in use, first connect the device to the construction vehicle through the top of the main body 1, and place the device at the location where sampling is required by the construction vehicle, then start the hydraulic rod 201 to drive the sampling tube 203 to descend, and the sampling tube 203 will drive the sampling port 101 when descending and insert it into the soil. After the soil is collected, place the bag inside the working box 301, and then drive the sampling tube 203 to rise by the hydraulic rod 201, and then start the electric push rod 202, which will push the sampling tube 203 when working, so that the sampling tube 203 moves to the top of the fixing mechanism 3. Then, the sampling tube 203 is driven to rise again through the hydraulic rod 201, so that the top rod 204 squeezes the chassis 104, and then multiple top rods 204 will push the soil, causing the soil to fall into the bag inside the working box 301, and then the measuring sensor 103 and the electric push rod 102 are started. When the electric push rod 102 descends, it will push the measuring sensor 103 and the chassis 104 to squeeze the soil. When the chassis 104 squeezes the soil, the chassis 104 will perform real-time measurement and apply pressure to the soil sample block until the soil sample block collapses. At this time, the measuring sensor 103 will record the maximum resistance value of the collapse of the soil sample block to complete the measurement. When soil falls into the working box 301, the motor 303 is started. When the motor 303 is working, the gears 304 are driven to rotate through the teeth on the output end. At the same time, when the motor 303 is working, the T-bar 305 is driven through the cross plate 309, so that the T-bar 305 rotates inside the special-shaped disk 302. When the T-bar 305 rotates to the protrusion on the special-shaped disk 302, the T-bar 305 moves toward the soil in the cross plate 309, and then rotates with the rotation of the cross plate 309. When the T-bar 305 moves forward, the moving T-bar 305 brings the fixed frame 307, so that the fixed frame 307 drives the swing plate 408 is attached to the surface of the bag filled with soil, and then when the T-bar 305 rotates with the cross plate 309, the roller at the bottom of the T-bar 305 will contact the inner wall of the special-shaped disk 302 and rotate. When the roller rotates, the rotating roller will pass through the special-shaped bar 308, so that the special-shaped bar 308 drives the swing frame 306 to reciprocate inside the fixed frame 307. At this time, the reciprocating swing frame 306 will squeeze the soil through the swing plate 408, which can ensure that the soil reaches a certain density before the compression test, while maintaining the integrity of the soil, avoiding bumps when the soil falls, resulting in incompleteness and affecting the accuracy of compaction measurement.When the swing frame 306 reciprocates inside the fixed frame 307, the reciprocating swing frame 306 will drive the shaft 401 to rotate synchronously. When the swing frame 306 drives the shaft 401 to rotate, the rotating shaft 401 will squeeze the inclined rod 402. After the inclined rod 402 is squeezed, it will press against the shaft 401 to rotate the shaft 401. When the shaft 401 rotates, it will push the two-way tooth plate 404 through the moving rod 403 to make the two-way tooth plate 404 rotate around the connecting rod 405. When the connecting rod 405 rotates, the rotating connecting rod 405 will drive the rack 407 to slide inside the swing frame 306. Since there are four racks 407, and two of them are in a group, when the connecting rod 405 rotates, The two sets of racks 407 will slide one after the other. When the two sets of racks 407 are sliding, the racks 407 will drive the swing plate 408 to make the swing plate 408 rotate in contact with the surface of the soil. At this time, the swing plate 408 rotating on the soil surface will squeeze the soil during rotation, so that the soil can cover a wider area when the swing plate 408 squeezes the soil, ensuring that the soil is evenly compacted, avoiding unevenness when the swing frame 306 drives the swing plate 408 to squeeze the soil. At the same time, when the swing plate 408 rotates, it can also reduce the situation where the swing plate 408 is over-pressured when squeezing the soil, avoiding the situation where the soil is broken before measurement due to excessive pressure and uneven squeezing, affecting the measurement results. When the rack 407 is rotated by the bidirectional tooth plate 404, the rack 407 will slide inside the swing frame 306. When the rack 407 slides, the sliding rack 407 will drive the elastic plate 502 to move through the fixed rod 501. Since the elastic plate 502 is elastic, the elastic plate 502 will shake when the elastic plate 502 moves. When the elastic plate 502 shakes, the shaking elastic plate 502 will drive the sliding plate 506 through the movable plate 503, so that the sliding plate 506 slides inside the limiting plate 504. When the sliding plate 506 slides, the sliding sliding plate 506 will drive the spring block 505 to shake. When the spring block 505 shakes, it will periodically collide with the side wall of the swing plate 408. At this time, the collision force generated by the spring block 505 on the side wall of the swing plate 408 can further destroy the structure between the soil particles, making them more closely arranged, thereby increasing the density of the soil.When the moving rod 403 pushes the two-way tooth plate 404 to reciprocate, the rotating two-way tooth plate 404 will drive the connecting rod 405 to rotate. When the connecting rod 405 rotates, it will drive the air outlet frame 602 to rotate through the cylindrical rod 601. When the air outlet frame 602 rotates, the rotating air outlet frame 602 will drive the piston plate 603 to squeeze the telescopic plate 604 in the rotating direction of the cylindrical rod 601. After being squeezed, the telescopic plate 604 will push against the piston plate 603 in the air outlet frame. 602, the piston plate 603 will squeeze the gas inside the air outlet frame 602 when sliding, and the gas inside the air outlet frame 602 will be squeezed and sprayed into the space between the two air collecting bags 609 through the front end of the air outlet frame 602, so that the air collecting bags 609 will expand slightly. At this time, when the swing plate 408 is pushed by the rack 407 to deflect, the deflected swing plate 408 will pull the C-shaped rod 606 through the limit rod 608, so that the C-shaped rod 606 rotates. When the C-shaped rod 606 rotates, its middle part will rotate on the limit plate 406. When the C-shaped rod 606 rotates, the rotating C-shaped rod 606 will drive the roller 607 to slide from the opening of the air collecting bag 609. When the roller 607 slides, the roller 607 will squeeze the opening of the air collecting bag 609, so that part of the gas inside the air collecting bag 609 is concentrated at the rear end of the air collecting bag 609, and the rear end of the air collecting bag 609 is expanded. After the air collecting bag 609 expands, a buffer layer will be formed between the swing plate 408 and the spring block 505, which can reduce the impact force of the spring block 505 when the spring block 505 hits the swing plate 408, so as to avoid the soil becoming loose due to excessive impact force when the spring block 505 hits the side wall of the swing plate 408, and to avoid the soil collapsing before measurement, so that the measuring sensor 103 cannot measure the soil, thereby affecting the measuring effect of the measuring sensor 103.
