An engineering pavement compactness detection device and detection method

Abstract

This invention discloses a device and method for testing the compaction degree of engineering pavement, comprising a machine body composed of a vertical plate and a horizontal plate. Through the coordinated use of a lifting mechanism, a clamping mechanism, a pressing mechanism, a blade-removing mechanism, an auxiliary mechanism, a leveling mechanism, and a soil-taking mechanism, the device first completely presses the ring cutter body into the soil, then removes the ring cutter body from the soil. Next, two sets of leveling blades level the excess soil at the top and bottom of the ring cutter body. Finally, the soil-taking blade rotates and moves downwards to remove the soil from inside the ring cutter body, which falls into the heating frame. After the soil is completely removed, the reading on the electronic scale is recorded. Then, the heating element on the inner wall of the heating frame is activated to dry the soil until the electronic scale reading no longer changes. The electronic scale reading is recorded again. Based on the two readings and the corresponding calculation formula, the soil compaction degree can be determined. The entire process is automated, meeting the needs of workers.

[0063] Those skilled in the art will understand that the extension or retraction of the output end of the third electric push rod 801 causes the moving plate 802 to move to the left or right; the extension or retraction of the output end of the fourth electric push rod 804 causes the soil-taking blade 805 to move downward or upward; and the output end of the fourth drive motor 806 drives the drive wheel 807 to rotate, which, under the action of the belt, causes the driven wheel 808 to rotate, thereby causing the fourth electric push rod 804 and the soil-taking blade 805 to rotate as a whole.

[0064] To clearly describe the working principle of this invention, we will use... Figure 1 The explanation is as follows:

[0065] S1. Move the machine body 1 to the location to be tested and fix it. Drive the first lead screw 201 to rotate through the output end of the first stepper motor 203, so that the lifting plate 103 moves downward, driving the ring cutter body 104 that is clamped and fixed to move downward and press into the ground. Due to the clamping method, the top of the ring cutter body 104 is still exposed above the ground. At this time, the clamping mechanism 3 releases the clamping of the ring cutter body 104, and the lifting plate 103 is reset under the action of the output end of the first stepper motor 203.

[0066] S2. The output end of the first electric push rod 406 extends, causing the pressure plate 407 to move downward, so that the pressure plate 407 is located below the two sets of first clamping members 305. The output end of the second stepper motor 404 drives the second lead screw 402 to rotate, so that the movable block 405 moves along the second guide rod 403, causing the pressure plate 407 to be located at the bottom center of the lifting plate 103.

[0067] S3. Continue to drive the first stepper motor 203, so that the lifting plate 103 moves downward, driving the pressure plate 407 to move downward and smash the top of the ring cutter body 104. Repeat this several times until the ring cutter body 104 is completely pressed into the soil. Then, the pressure plate 407 is reset with the cooperation of the output end of the second stepper motor 404 and the output end of the first electric push rod 406. The lifting plate 103 is also reset under the action of the output end of the first stepper motor 203.

[0068] S4. The output end of the second electric push rod 506 extends, causing the lifting component 507 to move downward, so that the lifting component 507 is located below the two sets of first clamping components 305. The output end of the third stepper motor 504 drives the third lead screw 502 to rotate, causing the L-shaped plate 505 to move to the right, causing the lifting component 507 to move to the right and be located at the bottom center of the lifting plate 103.

[0069] S5. The output of the first stepper motor 203 drives the first lead screw 201 to rotate, causing the lifting plate 103 and the lifting component 507 to move downwards as a whole. At the same time, the output of the first drive motor 510 is started, causing the drive gear 511 to rotate, which drives the driven gear 512, the first cylinder 508, the second cylinder 509, and the drilling teeth to rotate as a whole, realizing drilling. The bottom of the ring cutter body 104 passes through the interior of the first cylinder 508 and the second cylinder 509. When the two sets of cutters 517 move downwards to a position below the ring cutter body 104, the second... The output of the servo motor 516 drives the second threaded rod 514 to rotate, causing the two sets of cutters 517 to move closer to each other. The two sets of cutters 517 support the ring cutter body 104. Then, with the cooperation of the output of the first stepper motor 203 and the output of the first drive motor 510, the first cylinder 508, the second cylinder 509 and the drilling teeth are drilled out of the ground as a whole, and the ring cutter body 104 is taken out of the ground. It is worth noting that, since the bottom of the second cylinder 509 has a conical structure, excess soil will slide out along the inclined surface inside the second cylinder 509.

[0070] S6. With the cooperation of the output end of the second electric push rod 506 and the output end of the third stepper motor 504, the lifting component 507, the first cylinder 508 and the second cylinder 509 are reset as a whole. Then, the output end of the fifth stepper motor 604 drives the fifth lead screw 602 to rotate, causing the movable frame 605 to move forward, thereby driving the support cylinder 610 to move forward. At the same time, the output end of the sixth stepper motor 608 drives the sixth lead screw 606 to rotate, causing the movable component 609 to move to the right, driving the support cylinder 610 to move to the right, so that the support cylinder 610 is located directly below the second cylinder 509. And again, the output end of the second electric push rod 506 extends, causing the lifting component 507 to move downward, so that the bottom end of the second cylinder 509 is in contact with the top of the support cylinder 610.

[0071] S7. The second threaded rod 514 is driven to rotate by the output end of the second servo motor 516, so that the two sets of cutters 517 move away from each other and the ring cutter body 104 falls into the inside of the support cylinder 610. Then, the second cylinder 509 continues to reset under the contraction of the output end of the second electric push rod 506.

[0072] S8. The output end of the third servo motor 621 drives the third threaded rod 619 to rotate, causing the two sets of second clamping members 622 to move closer to each other and clamp and fix the outer surface of the ring cutter body 104. The output end of the third drive motor 613 drives the connecting frame 614 to rotate, causing the two sets of second clamping members 622 to face the flattening mechanism 7. Under the drive of the output end of the sixth stepper motor 608, the two sets of second clamping members 622 move to the left.

[0073] S9. The output end of the eighth stepper motor 704 drives the eighth lead screw 702 to rotate, causing the moving part 705 to move to the right along the eighth guide rod 703, thereby driving the two sets of leveling blades 706 to move to the right. The two sets of leveling blades 706 respectively level the excess soil at the top and bottom of the ring cutter body 104.

[0074] S10. Then, driven by the output of the sixth stepper motor 608, the two sets of second clamping members 622 move to the right, and the output of the third drive motor 613 drives the connecting frame 614 to rotate, so that the two sets of second clamping members 622 face the heating frame 106. Under the action of the output of the seventh stepper motor 617, the two sets of second clamping members 622 move downward, driving the clamped ring cutter body 104 to move downward, so that the ring cutter body 104 is located inside the heating frame 106. Then, through the extension of the output of the third electric push rod 801, the moving plate 802 moves to the left. Then, under the action of the output of the seventh stepper motor 617, the ring cutter body 104 moves upward, so that the top of the ring cutter body 104 is in the groove 803 at the bottom of the moving plate 802. The soil is brought into contact with the wall, and then, with the cooperation of the output end of the fourth electric push rod 804 and the output end of the fourth drive motor 806, the soil-removing blade 805 rotates and moves downwards, removing the soil from inside the ring cutter body 104 and letting it fall into the heating frame 106. Since the top of the ring cutter body 104 is sealed by the moving plate 802, the soil will not splash from above, improving the accuracy of the measurement. After the soil is completely removed, the reading of the electronic scale 105 is recorded. Then, the electric heating element on the inner wall of the heating frame 106 is activated to dry the soil until the reading of the electronic scale 105 no longer changes. The reading of the electronic scale 105 is recorded again. Based on the two readings and the corresponding calculation formula, the compaction degree of the soil can be obtained. The whole process is automated, convenient and fast, meeting the needs of the staff.

Drive the first lead screw (201) to rotate through the output end of the first stepper motor (203), so that the lifting plate (103) moves downward, driving the fixed ring cutter body (104) to move downward and press into the ground. Due to the clamping method, the top of the ring cutter body (104) is still exposed above the ground.

Then, the pressure plate (407) is reset under the cooperation of the output end of the second stepper motor (404) and the output end of the first electric push rod (406). The lifting plate (103) is also reset under the action of the output end of the first stepper motor (203). S4. The output end of the second electric push rod (506) extends, causing the lifting component (507) to move downward, so that the lifting component (507) is located below the two sets of first clamping components (305).

S5. The output of the first stepper motor (203) drives the first lead screw (201) to rotate, causing the lifting plate (103) and the lifting component (507) to move downward as a whole.

The bottom of the ring cutter body (104) passes through the interior of the first cylinder (508) and the second cylinder (509). When the two sets of cutters (517) move downward to a position below the ring cutter body (104), the... The output of the second servo motor (516) drives the second threaded rod (514) to rotate, causing the two sets of cutters (517) to move closer to each other. The two sets of cutters (517) support the ring cutter body (104). Then, with the cooperation of the output of the first stepper motor (203) and the output of the first drive motor (510), the first cylinder (508), the second cylinder (509) and the drilling teeth are drilled out of the ground as a whole, and the ring cutter body (104) is taken out of the ground. It is worth noting that, since the bottom of the second cylinder (509) is conical, excess soil will slide out along the inclined surface inside the second cylinder (509). S6. With the cooperation of the output end of the second electric push rod (506) and the output end of the third stepper motor (504), the lifting component (507), the first cylinder (508) and the second cylinder (509) are reset as a whole. Then, the output end of the fifth stepper motor (604) drives the fifth lead screw (602) to rotate, causing the movable frame (605) to move forward, thereby driving the support cylinder (610) to move forward. At the same time, the output end of the sixth stepper motor (608) drives the sixth lead screw (606) to rotate, causing the movable component (609) to move to the right, driving the support cylinder (610) to move to the right, so that the support cylinder (610) is located directly below the second cylinder (509). And again, the output end of the second electric push rod (506) extends, driving the lifting component (507) to move downward, so that the bottom end of the second cylinder (509) is in contact with the top of the support cylinder (610). S7. The second threaded rod (514) is driven to rotate by the output end of the second servo motor (516), so that the two sets of cutters (517) move away from each other and the ring cutter body (104) falls into the inside of the support cylinder (610). Then, the second cylinder (509) continues to reset under the contraction of the output end of the second electric push rod (506). S8. The output end of the third servo motor (621) drives the third threaded rod (619) to rotate, so that the two sets of second clamping parts (622) move closer to each other and clamp and fix the outer surface of the ring cutter body (104). The output end of the third drive motor (613) drives the connecting frame (614) to rotate, so that the two sets of second clamping parts (622) face the flattening mechanism (7), and under the drive of the output end of the sixth stepper motor (608), the two sets of second clamping parts (622) move to the left. S9. The output end of the eighth stepper motor (704) drives the eighth lead screw (702) to rotate, causing the moving part (705) to move to the right along the eighth guide rod (703), thereby driving the two sets of leveling blades (706) to move to the right. The two sets of leveling blades (706) respectively level the excess soil at the top and bottom of the ring cutter body (104). S10. Then, driven by the output of the sixth stepper motor (608), the two sets of second clamping members (622) move to the right, and the output of the third drive motor (613) drives the connecting frame (614) to rotate, so that the two sets of second clamping members (622) face the heating frame (106). Under the action of the output of the seventh stepper motor (617), the two sets of second clamping members (622) move downward, driving the clamped ring cutter body (104) to move downward, so that the ring cutter body (104) is located inside the heating frame (106). Then, through the extension of the output of the third electric push rod (801), the moving plate (802) moves to the left. Then, under the action of the output of the seventh stepper motor (617), the ring cutter body (104) moves upward, so that the top of the ring cutter body (104) and the bottom of the moving plate (802) are concave. The inner wall of the groove (803) abuts against the soil. Then, with the cooperation of the output end of the fourth electric push rod (804) and the output end of the fourth drive motor (806), the soil-taking knife (805) rotates and moves downward to take out the soil inside the ring knife body (104) and fall into the heating frame (106). Since the top of the ring knife body (104) is sealed by the action of the moving plate (802), the soil will not splash from the top, which improves the accuracy of the measurement. After the soil is completely taken out, the reading of the electronic scale (105) is recorded. Then, the electric heating element on the inner wall of the heating frame (106) is activated to dry the soil until the reading of the electronic scale (105) no longer changes. The reading of the electronic scale (105) is recorded again. The compaction degree of the soil can be obtained from the two readings and the corresponding calculation formula. The whole process is automated, convenient and fast, and meets the needs of the staff.
