Description

Technical Field

[0001] The invention relates to the field of construction equipment detection, and in particular to a grouting material fullness detection device and method. Background Art

[0002] Prefabricated buildings are common components in modern buildings. Prefabricated buildings, such as prefabricated shear walls, are prefabricated in factories and then transported to on-site installation, which can significantly shorten the construction period. Prefabricated shear walls generally require grouting during installation. After the grouting construction, the grouting fullness needs to be tested to ensure the safety and stability of the structure. If the grouting is not full, the integrity and bearing capacity of the shear wall will be weakened, which may cause cracks, deformation or even damage to the structure when it is under stress, affecting the safe use of the building.

[0003] When the prior art detects the fullness of grouting, the acoustic wave detection method is generally used, which mainly uses the propagation characteristics of acoustic waves in different media to judge the fullness of the grouting material. However, when the prior art detects shear walls, in order to ensure the standardization of the detection, it is generally necessary to first divide the detection area on the wall, and then mark the detection points at fixed distances, and then detect the detection points one by one to ensure a comprehensive detection of the wall. However, this method is not only cumbersome to operate and significantly increases labor costs, but also has low detection efficiency, which affects the construction progress.

[0050] A detection method of a grouting material fullness detection device comprises the following steps:

[0051] S1: Adjust the track height to 100 degrees to determine the detection area;

[0052] S2: The second linear motor 104 drives the detection box 300 to move to the detection area;

[0053] S3: The detection box 300 climbs along the rack track 202, and performs a knocking and echo detection at a specified interval each time.

[0054] The working process of the grouting material fullness detection device and method is as follows:

[0055] First, the detection device is fixed to the shear wall as a whole by tightening the clamps 102 at both ends and clamping them at both ends of the prefabricated shear wall. Further, the linear motors 103 on both sides can be started at the same time to drive the track 100 to move along the track 2 101 in the vertical direction. After adjusting to the height area to be detected, the drive motor 302 is started, and the drive motor 302 drives the gear 1 303 to rotate. Through the meshing transmission of the gear 1 303 and the rack track 202, the detection box 300 is driven to climb along the rack track 202. The rotation of the gear 1 303 drives the gear 2 304 to accelerate the rotation. Further, through the coaxial transmission of the gear 2 304 and the cam 305, the cam 305 is driven to rotate, and the slider 1 306 is periodically pushed down, so that the slider 1 306 is moved upward. The inside of the sealed chamber 5 322 performs piston movement, and the gas is continuously pumped into the sealed chamber 1 308 through the exhaust pipe 307. The gas pushes the piston 1 309 upwards and compresses the spring 1 313. When the piston 1 309 moves up to contact the upper magnetic ring 2 314 and pushes the magnetic ring 2 314, the magnetic ring 2 314 moves up a short distance. Since a set of magnetic poles of the magnetic ring 2 314 and the magnetic ring 1 310 are close to each other, they attract each other. When the slider 2 311 moves up a short distance as a whole, since the lower magnetic ring 2 314 is separated from the lower magnetic ring 1 310, the distance increases and the magnetic force decreases, while the distance between the upper magnetic ring 2 314 and the upper magnetic ring 1 310 becomes smaller, and the magnetic force increases. Therefore, under the attraction of the magnetic force, the slider 2 311 will move upwards. The upper magnetic ring 2 314 is attracted to the upper magnetic ring 1 310. At this time, the slider 2 311 moves up to trigger the switch 1 312, and the drive motor 302 is controlled to stop. Further, the slider 2 311 moves up to make the valve block 315 move up so that the internal channel of the valve block 315 is connected with the sealed chamber 2 401. Under the elastic force of the spring 1 313, the piston 1 309 is pushed down to discharge the internal gas of the sealed chamber 1 308 into the sealed chamber 2 401 through the valve block 315 and the air inlet pipe 317, and the slider 3 402 and the detection rod 400 are pushed to move toward the shear wall. When the detection rod 400 continues to move after contacting the shear wall, the design of the spring between the detection rod 400 and the slider 3 402 can ensure that the detection rod 400 is in contact with the shear wall. There is a certain pressing force to ensure the contact between the detection rod 400 and the shear wall and the signal absorption efficiency, so as to ensure the detection effect. During the movement of the slider 3 402, after the slider 3 402 moves through the connecting pipe 319, the piston ring position of the slider 3 402 close to the sealing chamber 1 308 is located between the connecting pipe 319 and the exhaust port 320. At this time, the gas inside the sealing chamber 2 401 enters the sealing chamber 4 501 through the connecting pipe 319, pushing the piston 3 506 to move toward the piston 2 507, the reset spring 508 is stretched, and the storage spring 509 is compressed. When the piston 3 506 continues to move after contacting with the protrusion 2 504, the slider 5 502 is pushed toward the inside of the detection box 300 through the inclined surface of the protrusion 2 504.The movement of the slider 502 drives the protrusion 1 503 to move toward the inside of the detection box 300 to release the blocking of the piston 2 507, so that the piston 2 507 drives the detection hammer 500 to pop out in the direction of the shear wall under the elastic force of the storage spring 509, and hits the wall just above the detection rod 400, generating vibration and impact signals. The detection elements including the acceleration sensor inside the detection rod 400 receive the feedback signal from the inside of the wall and transmit it to the detection instrument 301. The detection instrument 301 analyzes the characteristics of the received fluctuation signal, and judges the existence and type of grouting defects according to the characteristic changes of the vibration signal during the detection process, such as amplitude, frequency and other characteristics, and then judges the overall fullness of the grouting, so as to make timely construction remedial according to the detection results.

[0056] After one inspection is completed, as piston 1 309 continues to pump air into sealing chamber 2 401, the internal pressure of sealing chamber 2 401 and sealing chamber 4 501 continues to increase, and the piston ring of slider 3 402 close to the sealing chamber 1 308 continues to move to expose the exhaust port 320, so that excess gas is discharged through the exhaust port 320, until piston 1 309 moves down to contact with magnetic ring 2 314 below and pushes magnetic ring 2 314 to move a short distance. Similarly, under the magnetic force of magnetic ring 1 310 and magnetic ring 2 314, slider 2 311 moves down as a whole, so that valve block 315 moves down and breaks away from the blockage of intake pipe 317. Similarly, sealing chamber 1 308 cannot be connected to intake pipe 317 through valve block 315. 317 is connected. At this time, under the resetting action of the spring three 417 and the reset spring 508, the internal pressure gas of the detection instrument 301 and the sealing chamber two 401 is discharged through the air inlet pipe 317 and the air outlet pipe 316, so that the detection rod 400 and the detection hammer 500 are reset. It should be noted that in this process, the slider three 402 is reset so that the slider three 402 is close to the piston ring on the side of the sealing chamber one 308. After passing through the connecting pipe 319, the internal pressure gas of the sealing chamber four 501 can pass through the side wall of the middle section of the slider three 402 and then be discharged through the exhaust port 320, so that the internal gases of the sealing chamber four 501 and the sealing chamber two 401 are discharged and reset synchronously through two groups of channels during the resetting process, thereby improving the resetting speed.

[0057] During the extension of the detection rod 400, the gear four 405 can be pushed to rotate through the rack group 403, which further drives the gear three 404 to rotate. The transmission of the gear three 404 and the gear five 406 drives the baffle 407 to rotate synchronously to break away from the obstruction of the detection rod 400. At the same time, through the rotation of the rotating shaft 2 416, the pull rope 412 is wound up, driving the special-shaped slider 408 to slide inside the baffle 407 in the direction away from the spring 2 414, so that the spring 2 414 is stretched. At the same time, the movement of the special-shaped slider 408 reduces the internal pressure of the sealing chamber 3 409 , the external coupling agent is sucked into the sealed cavity three 409 through the hose. When the rack group 403 completely passes through the gear four 405, the shaped slider 408 moves upward to the block 413, and the block 413 is pushed into the baffle 407 through the bevel at the bottom of the block 413, so as to move through the block 413, and then the block 413 is engaged with the right-angled edge at the top of the block 413 to prevent the shaped slider 408 from resetting. When the detection rod 400 retracts and resets, the rack group 403 moves through the gear four 405 to drive the gear four 405 to reverse, and further drives the baffle 4 07 is reversed, the second shaft 416 is reversed to release the winding of the pull rope 412, and when the gear 405 passes through the rack group 403, the detection rod 400 is reset, and the baffle 407 is also reversed to be parallel to the detection surface of the detection rod 400. Under the contact pressure of the slider 411 with the detection rod 400, the slider 411 is pushed toward the inside of the special-shaped slider 408, and the slider 411 further pushes the block 413 through the hypotenuse of the block 413 to disengage the special-shaped slider 408, so that the special-shaped slider 408 is out of the limit state, and the spring 414 is pressed against the second slider 411. The shaped slider 408 moves and resets under the action of the elastic force. During the resetting process of the shaped slider 408, the residual coupling agent in the detection area at the end of the detection rod 400 is scraped and cleaned by the slider four 411. At the same time, the coupling agent inside the sealing cavity three 409 is compressed by the downward movement of the shaped slider 408, so that it passes through the one-way valve and is squeezed out from the nozzle 410, thereby realizing automatic replacement after the residual coupling agent on the surface of the detection rod 400 is removed, which not only ensures the improvement of the gap between the detection rod 400 and the detection area, but also reduces signal loss, improves the clarity and accuracy of the detection signal acquisition, and effectively improves the accuracy of detection.

[0058] It should be noted that after completing one detection, after the slider 311 moves down to trigger the switch 321, the switch 321 can delay the start of the drive motor 302 for a period of time, and the detection work is cyclically performed. The delayed start can ensure the time required for resetting.

[0059] It should be noted that, before each detection work starts, the gas needs to be pumped into the sealed chamber 1 308 by driving the cam 305 to push the reset piston 1 309 upward until the upper slider 2 311 is pushed upward synchronously, and the driving motor 302 is suspended when the detection work starts and when it is reset. Therefore, except for the detection and reset time, the gap time standard for each detection work is to fill the sealed chamber 1 308 with a specified amount of gas, and the amount of gas pumped into the sealed chamber 1 308 through the slider 1 306 in each rotation cycle of the cam 305 is also consistent. Therefore, the gap of each detection work requires the cam 305 to rotate a specified number of times to complete the total amount of gas pumped in, and through the coaxial design of the cam 305 and the gear 2 304, This indicates that the gap of each detection work requires Gear 2 304 and Gear 1 303 to rotate a specified number of times, and thus the distance that the gap of Gear 1 303 climbs on the rack track 202 for each detection work is also roughly the same. Therefore, this indicates that the device can automatically perform a detection operation every time the detection box 300 is lifted a certain distance. Therefore, the device can perform automatic equidistant detection along track three 201. Compared with the traditional manual detection after manual marking and division, automatic equidistant detection can be performed without marking points, and the detection efficiency is high. Moreover, the force of each striking stroke of the detection hammer 500 is consistent, ensuring that the excitation conditions of each detection input are consistent, thereby improving the comparability and repeatability of the data, improving the reliability of the data, and effectively improving the accuracy of the detection.

[0060] It should be noted that each time the detection box 300 moves to the highest point of the track three 201, it completes the detection of a group of vertical areas. At this time, the linear motor 2 104 drives the slide 200 to move a specified distance to the next detection point, and continues to detect along the track three 201. In order to ensure the cyclic operation of the detection box 300, after the detection box 300 rises and completes the detection work at the highest point, the distance between the detection box 300 and the top of the track three 201 is just half of the detection travel distance. The detection box 300 continues to rise and stops after contacting the top of the track three 201. When the linear motor 2 104 moves to detect the next horizontal area, the detection box 300 can move from top to bottom to detect the next group of areas from top to bottom. The detection box 300 moves down to When the highest detection point is reached, half of the subsequent detection stroke is just completed, thereby driving the detection rod 400 and the detection hammer 500 to extend for detection. Similarly, when the detection box 300 moves to a set of detection points at the lowest detection point to complete the detection, the distance between the detection box 300 and the slide 200 is also half of the detection stroke distance, so that the detection box 300 can be cyclically moved for detection. In order to enhance the automation effect of the device, in addition to manual operation by the staff, a switch group can be set at the top and bottom of the track three 201 to ensure that after the detection box 300 moves to the extreme position and triggers the switch group, the drive motor 302 will promptly pause the automatic movement of the linear motor two 104. After the linear motor two 104 moves a specified distance or a specified position, the drive motor 302 starts to move in the opposite direction, thereby ensuring that the detection work is automatically and stably carried out.
