Description

Technical Field

[0001] The present invention relates to the technical field of concrete engineering detection, and more particularly, to an intelligent monitoring device for concrete engineering construction. Background Art

[0002] During the concrete construction process, first, the pouring equipment, formwork, steel bars and other equipment are inspected, then pouring is carried out, and after pouring, vibration is carried out to ensure the compactness of the poured concrete. After vibration, the quality of the concrete in the pouring area is also analyzed and judged. Only when it meets the construction quality can the subsequent construction steps be entered, otherwise timely remedial construction is required.

[0003] The existing technology generally detects the quality of concrete pouring through manual inspection by on-site technical personnel responsible. By observing the defects on the surface of the concrete after pouring and vibration, including honeycombing, pockmarking, cracks or obvious air bubble accumulation and other defects, or by judging during the vibration process. For example, when the vibrating rod is inserted into the concrete, if the sound gradually changes from low frequency to high frequency and is stable, it indicates that the internal air has been discharged and the vibration is sufficient. However, these manual monitoring methods are easily affected by the light, viewing angle and construction noise at the construction site during observation, and the judgment process has a strong dependence on subjective experience, making it difficult to obtain accurate and stable detection results and unable to provide stable detection for the overall concrete project.

[0004] How to invent an intelligent monitoring device for concrete engineering construction to improve these problems has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

The contact parts of the second slider, the third slider, the second hydraulic cavity, the piston four, and the first hydraulic cavity are sealed.

[0012] Preferably, the piston four is designed in a T shape, and one end of the piston four extends into the second hydraulic cavity.

The one-way shafts are rotatably connected with the piston four, and torsion springs for resetting are arranged at the connection parts.

[0013] Preferably, the cleaning mechanism includes a sealing ring opened inside the inspection vehicle. A rotating ring is rotatably connected inside the sealing ring.

[0017] In summary, the beneficial effects of the present invention are as follows:

[0018] 1. Through the meshing cooperation of the driving motor and the track, every time the inspection vehicle travels a specified distance, a specified amount of gas will be pumped into the first sealing cavity through the cooperation of the cam and the second piston, and driven by the driving force of the gas, the inspection probe will be driven to penetrate into the concrete surface layer. Through the cooperation of the buffer mechanism, the inspection probe will stop and complete a detection, realizing the equidistant automatic detection of the concrete engineering construction area. Moreover, the detection coverage is large, the detection points are uniform. Through the inspection probe, not only the objective accuracy of the detection is improved, the overall defects of the concrete engineering construction can be effectively detected in time, and the thickness and uniformity of the pouring can be detected at multiple points equidistantly as a whole. Moreover, manual operation of the detection is not required, which greatly improves the accuracy and efficiency of the detection and ensures the overall quality of the concrete engineering construction.

[0019] 2. During the cyclic detection process, when the piston III drives the detection probe to rise under the action of the spring elastic force, the driving gas inside the first sealing cavity is finally discharged into the sealing ring. The driving gas drives the rotation of the rotating ring and drives the impeller to rotate to provide water source, forming a gas-liquid mixture, and performing a rotating spray rinse on the detection probe from top to bottom. This not only reduces the usage amount of the aqueous solution and reduces the impact on concrete construction, but also through the synergistic action of compressed air and water flow, forms bubbles to impact and break the concrete slurry or impurities attached to the surface of the probe, avoiding the interference of residues on the ultrasonic signal transmission. At the same time, combined with the rotation of the rotating ring, it can achieve a non-dead-angle rotating rinse, ensuring the cleaning effect of the detection probe after detection, thereby ensuring the stability and accuracy of the subsequent detection process.

Specific embodiments

[0037] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Refer to Figure 1-14, the present invention provides an intelligent monitoring device for concrete engineering construction, including a detection vehicle 100 and a slide rail 200. A sliding seat 201 is slidably connected to the slide rail 200. A track 202 is connected to the side wall of the sliding seat 201. A driving mechanism, a detection mechanism and a cleaning mechanism are arranged inside the detection vehicle 100;

[0039] The driving mechanism includes a driving motor 102 arranged inside the detection vehicle 100. The output shaft of the driving motor 102 is connected to a driving wheel 103 and a first gear 104. It should be noted that the driving motor 102 is a double-headed motor, and the output shafts at both ends are respectively in transmission connection with the central rotating shafts of the driving wheel 103 and the first gear 104. A second sealing cavity 307 and a first sealing cavity 300 are formed inside the detection vehicle 100. A communication pipe 301 is arranged between the second sealing cavity 307 and the first sealing cavity 300 to connect them. A piston 308 with a spring is movably sleeved inside the second sealing cavity 307. A second gear 309 meshing with the first gear 104 is arranged inside the detection vehicle 100. The rotating shaft of the second gear 309 is connected to a cam 310 cooperating with the piston 308. Specifically, when the second gear 309 drives the cam 310 to rotate, the cam 310 can cyclically push the piston 308 to compress the air inside the second sealing cavity 307, and continuously pump the gas into the first sealing cavity 300 through the communication pipe 301 and the check valve inside the communication pipe 301. And a check valve for air intake is arranged in the second sealing cavity 307. When the piston 308 returns to the inside of the second sealing cavity 307 due to the elastic force of the spring, it sucks in gas from the outside, so as to continuously compress and pump the external gas into the first sealing cavity 300. A piston 302 with a spring is movably sleeved inside the first sealing cavity 300. A first slider 303 cooperating with the piston 302 is movably sleeved inside the detection vehicle 100. A first switch 304 cooperating with the bottom of the first slider 303 is arranged inside the detection vehicle 100;

[0040] It should be noted that a pressure rod is further arranged above the sliding seat 201 to provide pressure when the detection vehicle 100 travels, so as to ensure the meshing of the driving wheel 103 and the track 202;

[0041] The detection mechanism includes a sealed chamber three 400 opened inside the detection vehicle 100. An intake pipe 305 is provided between the sealed chamber one 300 and the sealed chamber three 400. The slider one 303 is provided with a communication groove one 306 that cooperates with the intake pipe 305. Inside the sealed chamber three 400, a piston three 401 with a spring is sleeved. The bottom of the piston three 401 is connected to a detection probe 500. Inside the detection vehicle 100, a slider two 404 and a slider three 405 that cooperate with the piston three 401 are sleeved. A buffer assembly is provided between the slider two 404 and the slider three 405. Inside the detection vehicle 100, a switch two 406 that cooperates with the slider two 404 is provided. Inside the detection vehicle 100, a switch three 407 that cooperates with the slider three 405 is also provided. An exhaust pipe 403 that communicates with the sealed chamber three 400 is opened inside the detection vehicle 100. The slider two 404 is provided with a communication groove two 412 that cooperates with the exhaust pipe 403.

[0042] It should be noted that the detection probe 500 is an ultrasonic probe in the prior art. Preferably, it can be a longitudinal wave straight probe, which uses a single crystal wafer to vertically emit longitudinal waves and is used to detect the uniformity and shallow defects inside the concrete.

[0043] Furthermore, the tops of the first slider 303, the bottoms of the first slider 303, and the tops of the second slider 404 are all designed as magnets. Inside the inspection vehicle 100, there are magnetic poles that attract the first slider 303 and the second slider 404. Specifically, taking the second slider 404 as an example, above the second slider 404 inside the inspection vehicle 100, there is a magnetic pole corresponding to and attracting the second slider 404. When the piston three 401 pushes the second slider 404 to move upward by a certain distance during the return stroke, the magnetic pole at the top of the second slider 404 approaches the magnetic pole arranged above the second slider 404 inside the inspection vehicle 100, resulting in an increase in magnetic force, causing the second slider 404 to be attracted and thus quickly reset. Since the gas discharge inside the third sealing cavity 400 is carried out step by step, through the design of the magnet, as long as the gas discharge inside the third sealing cavity 400 causes the internal pressure of the third sealing cavity 400 to reach a certain level, when the piston three 401 resets to the specified position and pushes the second slider 404 to move a specified distance, the second slider 404 can move upward with the assistance of magnetic force, directly causing the second communication groove 412 to accelerate upward and completely misalign with the exhaust pipe 403, closing the exhaust of the exhaust pipe 403, and triggering the second switch 406 by the pressing between the second communication groove 412 and the exhaust pipe 403. By means of the second slider 404, problems such as slow exhaust causing the piston three 401 to push the second slider 404 to gradually rise, the flow area gradually becoming smaller, and finally getting stuck near the flow critical value resulting in seal leakage are avoided. Similarly, the first slider 303 will, under the thrust of the upward and downward movement of the piston one 302, as long as a certain thrust is provided to make the first slider 303 move upward or downward by a small distance, the remaining stroke can be assisted by magnetic force to accelerate the upward or downward movement of the first slider 303, so that the first slider 303 quickly moves upward to misalign and block the intake pipe 305, or the first slider 303 accelerates downward to quickly connect the first sealing cavity 300 and the intake pipe 305, while pressing and triggering the first switch 304.

[0044] It should be noted that a linear motor is arranged at the bottom of the sliding seat 201, which can drive the sliding seat 201 and the track 202 to slide inside the slide rail 200. Cooperating with the sliding of the inspection vehicle 100 on the track 202, it can achieve full - coverage detection of the detection area by moving horizontally and vertically.

[0045] It should be noted that the track 202 is assembled by splicing, and the splicing length can be freely selected according to the length of the construction area. Moreover, since the driving wheel 103 travels on the track 202 in a meshing manner, when the driving wheel 103 travels a specified distance on the track 202, the number of rotations of the driving wheel 103, the first gear 104, and the second gear 309 is certain. Furthermore, the number of rotations of the cam 310 and the number of times of pushing the piston two 308 to move and pump air also tend to be certain. Further, by specifying the length of the track 202, the amount of gas filled into the first sealing cavity 300 when the driving wheel 103 passes through the length of one section of the track 202 can meet half of the gas amount required to push the first slider 303 to open and supply gas to the third sealing cavity 400. Therefore, when the driving wheel 103 passes through two sections of the track 202, a gas filling and detection process for the third sealing cavity 400 can be completed. By reasonably designing the number of the tracks 202 according to the actual detection area, when the detection vehicle 100 completes the last detection work each time it approaches the two side slides 201, the detection vehicle 100 maintains a distance of one section of the track 202 from the slide 201. When the detection vehicle 100 continues to move a distance of one section of the track 202, the detection vehicle 100 contacts the switch group arranged on the side wall of the slide 201. The switch group controls to drive the slide 201 to move a certain distance on the slide rail 200, and at the same time controls the driving motor 102 to rotate in the reverse direction, so that the detection vehicle 100 moves in the reverse direction on the track 202. Since the pumping of air by the rotation of the cam 310 is not affected by the rotation direction, when the detection vehicle 100 moves in the reverse direction, pumping can continue. When moving in the reverse direction for a distance of one section of the track 202, the detection work inside the detection vehicle 100 is carried out again until the detection vehicle 100 moves to the other side slide 201, thus ensuring the cyclic monitoring of the device. At the same time, it should be noted that since the detection vehicle 100 itself has a certain length, when designing the specific length and laying quantity of the track 202, the influence of the self-length of the detection vehicle 100 is taken into consideration. The connection relationship between the track 202 and the slide 201 can be fixed by plugging bolts. The track 202 with excessive length can pass through the slide 201 and adjust the effective length of the track 202 before fixing. Moreover, when the detection vehicle 100 starts the first group of work, the initial starting position of the driving wheel 103 can be set at a position half of the working stroke away from the slide 201.

[0046] Refer to Figure 7-9, the buffer assembly includes a first hydraulic chamber 408 and a second hydraulic chamber 409 opened inside the detection vehicle 100. The lower end of the second slider 404 and the upper end of the third slider 405 both extend into the second hydraulic chamber 409. A fourth piston 402 is movably sleeved inside the first hydraulic chamber 408. A one-way valve pipe is provided between the fourth piston 402 and the second hydraulic chamber 409 for communication. A spring is provided between the fourth piston 402 and the first hydraulic chamber 408. Gas is filled inside the second hydraulic chamber 409 and between the fourth piston 402 and the first hydraulic chamber 408. The contact parts of the second slider 404, the third slider 405, the second hydraulic chamber 409, the fourth piston 402, and the first hydraulic chamber 408 are sealed.

[0047] Further, the fourth piston 402 is designed in a T shape, and one end of the fourth piston 402 extends into the second hydraulic chamber 409. A slot 410 is opened at the end of the fourth piston 402 extending into the second hydraulic chamber 409. A pin 411 adapted to the slot 410 is provided at the bottom of the second slider 404. A spring is provided between the second slider 404 and the third slider 405. Two groups of one-way shafts 413 are provided on one side of the slot 410 close to the second hydraulic chamber 409. The one-way shafts 413 are rotatably connected to the fourth piston 402, and a torsion spring for resetting is provided at the connection.

[0048] It should be noted that the connection between the one-way shaft 413 and the fourth piston 402 is designed for one-way rotation, and the rotation direction of the one-way shaft 413 can only rotate along the rotation axis away from the slot 410.

[0049] Refer to Figure 7-14 , the cleaning mechanism includes a sealing ring 613 opened inside the detection vehicle 100. A rotating ring 600 is rotatably connected inside the sealing ring 613. Vanes 601 adapted to the inner side wall of the sealing ring 613 are provided on the outer side wall of the rotating ring 600. The exhaust pipe 403 is connected to the sealing ring 613. A communication cavity 608 is opened inside the rotating ring 600. A circle of communication holes 611 is opened on the outer side wall of the rotating ring 600. A plurality of spray pipes 606 connected to the communication cavity 608 are provided on the inner side wall of the rotating ring 600. An air inlet 612 connecting the communication holes 611 and the sealing ring 613 is opened on one side of the sealing ring 613 away from the exhaust pipe 403. A liquid discharge assembly is also provided inside the rotating ring 600.

[0050] Refer to Figure 2-14, the liquid drainage assembly includes a liquid storage cavity 605 opened inside the swivel ring 600. The liquid storage cavity 605 is communicated with the water tank 101. It should be noted that the water tank 101 continuously supplies liquid to the liquid storage cavity 605 by gravity through a pipeline. The water tank 101 can store liquid by itself or be supplied with liquid through an external pipeline. A plurality of liquid infusion cavities 602 are opened inside the swivel ring 600. The liquid infusion cavities 602 are designed in a cylindrical shape. A rotating shaft penetrating through the liquid infusion cavity 602 is arranged at the center of the liquid infusion cavity 602. A gear three 603 is connected to the top of the rotating shaft. An impeller 607 is arranged in the area of the rotating shaft located inside the liquid infusion cavity 602. A liquid inlet 609 communicating with the inside of the liquid infusion cavity 602 is opened on one side of the liquid infusion cavity 602 away from the axis of the swivel ring 600. A liquid discharge port 610 communicating with the inside of the communication cavity 608 is opened on one side of the liquid infusion cavity 602 close to the axis of the swivel ring 600. A gear ring 604 meshing with the gear three 603 is opened inside the inspection vehicle 100.

[0051] It should be noted that the position of the liquid infusion cavity 602 corresponds to the position of the spray pipe 606.

[0052] Furthermore, the outer edge of the impeller 607 is in contact with the inner wall of the liquid infusion cavity 602.

[0053] The working process of the intelligent monitoring device for a concrete engineering construction is as follows:

[0054] First, according to the concrete construction project, parallel slide rails 200 are laid on both sides of the area to be detected. At the same time, an appropriate number and length of tracks 202 are spliced and combined between two symmetrically arranged sliding seats 201 on the slide rails 200. Then, the inspection vehicle 100 is arranged on the track 202 to make the track 202 mesh with the driving wheel 103. Further, the driving motor 102 is started to drive the driving wheel 103 and the gear one 104 to rotate, so that the inspection vehicle 100 travels on the track 202 and conducts inspections.

[0055] When the inspection vehicle 100 is moving forward, the rotation of gear one 104 drives the acceleration of gear two 309, which further drives the rotation of cam 310, periodically pushing piston two 308 to compress the gas inside sealed chamber two 307 and pump it into sealed chamber one 300. The gas inside sealed chamber one 300 increases, pushing piston one 302 downward to compress the spring until piston one 302 moves downward to push slider one 303, causing slider one 303 to move downward to push switch one 304, driving motor 102 to stop moving. At the same time, the downward movement of slider one 303 causes communication groove one 306 to coincide and communicate with intake pipe 305, and the compressed gas inside sealed chamber one 300 enters sealed chamber three 400 through intake pipe 305. Further, the gas pressure inside sealed chamber three 400 increases, pushing piston three 401 downward, compressing the spring at the bottom of piston three 401. At the same time, the detection probe 500 connected to piston three 401 extends until piston three 401 moves downward to contact slider three 405 and push slider three 405 downward to the lowest position. At the same time, the downward movement of slider three 405 contacts switch three 407 and triggers it. At this time, the detection probe 500 is inserted into the surface layer of the concrete to be detected. Moreover, since slider three 405 moves downward to the limit position, piston three 401 no longer continues to move downward at this time, and the position of detection probe 500 is also fixed, ensuring the stability of the detection process. The power-on and startup of detection probe 500 are controlled by switch three 407 for several seconds to perform ultrasonic detection on the concrete pouring area here, and the detection data is transmitted to the on-site staff through the signal transmission device arranged inside inspection vehicle 100, facilitating the on-site staff to record and compare the detection results in real time.

[0056] It should be noted that during the downward movement of the third slider 405, the pressure inside the second hydraulic chamber 409 first decreases. The second slider 404 generates a downward force under the action of negative pressure and the spring elastic connection between the second slider 404 and the third slider 405. However, due to the blockage of the fourth piston 402 and the slot 410, it is difficult for the second slider 404 to move downward. At this time, the change in negative pressure inside the second hydraulic chamber 409 causes the second hydraulic chamber 409 to suck gas from the inside of the first hydraulic chamber 408 into the inside of the second hydraulic chamber 409. At the same time, the fourth piston 402 moves towards the inside of the second hydraulic chamber 409 to maintain pressure balance until the fourth piston 402 moves to engage with the pin 411 in the slot 410. At this time, the pin 411 moves downward and inserts into the slot 410. At this time, the fourth piston 402 retracts under the action of the spring elastic force between it and the first hydraulic chamber 408, and the second slider 404 and the pin 411 move downward synchronously, so that the second communication groove 412 communicates with the exhaust pipe 403. The pressurized gas inside the third sealing chamber 400 is discharged into the inside of the rotating ring 600 through the exhaust pipe 403. During this process, when the slot 410 and the pin 411 have relative displacement, the rotation of the one-way shaft 413 makes the pin 411 unaffected. Through the design of the buffer component, after the third slider 405 moves downward to the lowest position, the second slider 404 is blocked by the fourth piston 402. At this time, the gas exchange between the first hydraulic chamber 408 and the second hydraulic chamber 409 is carried out slowly through the one-way valve to achieve pressure balance, and the fourth piston 402 slowly extends, thereby causing the second slider 404 to move downward to connect the second communication groove 412 and the exhaust pipe 403. After the third slider 405 reaches the lowest position, the third piston 401 and the detection probe 500 can remain stationary for a certain period of time and carry out detection work, ensuring the stability of the detection process and the accuracy of the detection results.

[0057] Furthermore, during the above process, multiple sets of driving mechanisms and their corresponding components are provided, and the first sealing chambers 300 of each group are connected. Also, since the driving wheel 103 meshes with the track 202 for transmission, when the inspection vehicle 100 travels a specified distance, the number of rotation cycles of the driving wheel 103 and the first gear 104 is also a fixed value. Further, the number of working times of the second piston 308 being pushed by the rotation of the cam 310 to compress air is also a fixed value. Therefore, the total amount of gas entering the inside of the first sealing chamber 300 also tends to be the same. Therefore, whenever the inspection vehicle 100 travels a specified distance, a specified amount of gas can be pumped into the inside of the first sealing chamber 300, so that the first piston 302 moves downward to drive the first slider 303 to move and transport the gas inside the first sealing chamber 300 into the inside of the third sealing chamber 400 for a detection process. The inspection vehicle 100 realizes equal-distance automatic detection, realizes overall uniform detection, significantly improves the effect of detecting the overall concrete construction, effectively detects the defects in the concrete engineering construction in a timely manner, and conducts overall multi-point equal-distance detection on the pouring thickness and uniformity, effectively ensuring the overall quality of the concrete engineering construction.

[0058] When the gas inside the third sealing chamber 400 is discharged into the sealing ring 613 through the exhaust pipe 403, the gas pushes the rotating ring 600 to rotate through the blades 601 until it reaches the air inlet 612. The gas enters the inside of the communication chamber 608 through the air inlet 612 and the communication hole 611, and is further discharged through the nozzle 606. When the rotating ring 600 rotates, through the meshing transmission of the third gear 603 and the gear ring 604, the third gear 603 is driven to rotate. When the third gear 603 is stationary, the aqueous solution inside the liquid storage chamber 605 enters the liquid infusion chamber 602 through the liquid inlet 609. Blocked and separated by the impeller 607, it is difficult to enter the communication chamber 608 through the liquid discharge port 610. When the third gear 603 rotates, the impeller 607 rotates synchronously, and the aqueous solution entering through the liquid inlet 609 is transferred to the other liquid discharge port 610 through the rotation and transportation of the impeller 607, and is discharged into the communication chamber 608 through the liquid discharge port 610, flows into the nozzle 606, and is mixed with the compressed gas inside the communication chamber 608 and sprayed out through the end of the nozzle 606 to form a gas-liquid mixture, which flushes the surface of the detection probe 500. It should be noted that when the detection probe 500 detects, it is directly inserted into the concrete surface layer. The concrete that has just been vibrated and has not yet solidified has a certain fluidity. After the detection probe 500 with a Teflon anti-adhesion coating is inserted into the concrete surface layer, it can maintain good contact with the concrete surface layer. The flowing concrete is equivalent to a natural coupling agent, effectively ensuring the stability of the detection of the concrete construction layer. Moreover, the detection point is located on the concrete surface layer, and the reset and recovery are simple, without affecting the overall project quality. When the gas inside the third sealing chamber 400 enters the sealing ring 613 through the exhaust pipe 403, the pressure inside the third sealing chamber 400 continuously decreases. The piston 401 drives the detection probe 500 to rise under the action of the spring force. When the detection probe 500 rises, through the rotation of the rotating ring 600 and the spraying of the gas-liquid mixture inside the nozzle 606, the rising detection probe 500 can be sprayed and washed from top to bottom. This not only reduces the usage amount of the aqueous solution and the impact on the concrete construction, but also through the synergistic action of the compressed air and the water flow, forms bubble impacts to break the concrete slurry or impurities attached to the surface of the probe, avoiding the interference of residues on the ultrasonic signal transmission. At the same time, combined with the rotation of the rotating ring 600, it can achieve non-dead-angle rotary flushing, ensuring the cleaning effect of the detection probe 500 after detection, and thus ensuring the stability and accuracy of the subsequent detection process.

[0059] Further, after a part of the gas inside the third sealing chamber 400 is discharged, the third piston 401 resets and rises under the action of the spring elastic force. After contacting the second slider 404, it pushes the second slider 404 to rise. After the second slider 404 rises, it rises to push the second switch 406 through the cooperation of the magnet on the top of the second slider 404 and the magnet inside the detection vehicle 100. At the same time, the second communication groove 412 is misaligned with the exhaust pipe 403 to block the exhaust pipe 403. At this time, the detection work is completed, and the detection probe 500 has retracted into the detection vehicle 100. The second switch 406 controls the driving motor 102 to start, and controls the detection vehicle 100 to continue to move forward for the next detection work.

[0060] It should be noted that the elastic coefficient of the spring below the first piston 302 is greater than that of the spring below the third piston 401. Therefore, when the first sealing chamber 300 and the third sealing chamber 400 are connected, the first piston 302 will rise to pump gas into the third sealing chamber 400 until it is discharged through the exhaust pipe 403 until the specified air pressure is restored inside the third sealing chamber 400. At this time, the first piston 302 also rises under the action of the spring elastic force to push the first switch 304 to rise, so that the first communication groove 306 is misaligned with the intake pipe 305, and the subsequent cyclic gas storage work inside the first sealing chamber 300 is continued.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
