Description

Technical Field

[0001] The present application relates to the technical field of concrete surface bubble detection, and in particular to a concrete surface bubble detection device. Background Art

[0002] With the development of modern construction, concrete, a widely used building material, plays a crucial role in the safety and durability of building structures. Air bubbles are easily introduced into concrete during mixing, transportation, and pouring. If not properly managed, these bubbles can reduce the density and strength of the concrete, affecting its long-term performance. Therefore, effective detection and assessment of air bubbles on the concrete surface has become a key step in ensuring project quality.

[0003] Currently, technologies used to detect bubbles on concrete surfaces primarily include traditional methods such as visual inspection, manual tapping, drilling, water testing, formwork testing, pinhole testing, and specific gravity testing. These methods are simple to operate and low-cost, but their accuracy and reliability are limited, making them difficult to meet the requirements of high-precision engineering projects. In recent years, ultrasonic testing has gained popularity due to its high accuracy and non-destructive nature. It detects bubbles by measuring the propagation time and reflection of ultrasound waves in concrete.

[0004] While existing ultrasonic detection technology theoretically offers high accuracy, it still faces challenges in practical application. Newly poured concrete surfaces often have uneven surfaces, residual mortar, and aggregate. These factors can cause ultrasonic signals to scatter and attenuate, reducing detection accuracy. Utility Model Content

[0005] The purpose of this application is to solve the problems of unevenness, residual mortar and aggregate on the surface of newly poured concrete, which will cause scattering and attenuation of ultrasonic signals and reduce the accuracy of detection. This application provides a concrete surface bubble detection device.

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

[0007] The jacking assembly is installed at one end of the L-shaped base for driving the lifting slide to move along the length direction of the lifting slide, and a jacking assembly is installed at one end of the L-shaped base for driving the lifting slide to move along the length direction of the L-shaped base.

[0008] By adopting the above technical solution, by setting up the coordinated use of the jacking assembly and the driving assembly, it is convenient to use a grinder to grind the top of the concrete block placed on the top of the jacking platform, and then use the transmission rack 1 in conjunction with the transmission gear and the transmission rack 2 to drive the grinder away from the top of the concrete block while driving the ultrasonic detector to fit the flat surface of the polished top of the concrete block for detection, effectively reducing the problem of scattering and attenuation of ultrasonic signals caused by the uneven concrete surface, residual mortar and aggregate, and improving the detection accuracy of the device.

[0009] Furthermore, the driving assembly includes a lifting screw rotatably connected to the inside of the lifting slide, the lifting screw is threadedly connected to the lifting slide, the top of the L-shaped base is fixedly connected to a lifting motor, and the output end of the lifting motor is fixedly connected to the lifting screw.

[0010] By adopting the above technical solution and setting up the lifting screw and the lifting slide for use together, starting the lifting motor can drive the lifting slide to drive the ultrasonic detector to move along the length direction of the lifting slot, effectively improving the practicality of the device.

[0011] Furthermore, the lifting assembly includes a lifting electric push rod fixedly connected to one end of the L-shaped base, the output end of the lifting electric push rod passes through the support platform and is fixedly connected to the lifting platform, and the four corners of the bottom of the lifting platform are fixedly connected with a guide slide rod, one end of the guide slide rod passes through the support platform and is slidably connected to the support platform.

[0012] By adopting the above technical solution and setting up the coordinated use of the jacking electric push rod and the guide slide rod, starting the jacking electric push rod can push the jacking platform to drive the concrete block to move stably along the length direction of the guide slide rod, thereby further improving the practicality of the device.

[0013] Furthermore, friction lines are provided on the top of the lifting platform.

[0014] By adopting the above technical solution and providing the friction lines, the friction force on the top of the jacking platform is effectively improved, thereby improving the stability between the concrete block and the jacking platform.

[0015] Furthermore, the bottom of the follower skateboard is fixedly connected to a horn head, the top of the follower skateboard is fixedly connected to a dust suction pump, the input end of the dust suction pump is connected to the horn head through a pipe, the top of the follower skateboard is fixedly connected to a conical dust collecting barrel, and the output end of the dust suction pump is connected to the conical dust collecting barrel through a pipe.

[0016] By adopting the above technical solution and arranging the use of a dust suction pump in conjunction with a horn head, it is convenient to drive the follower slide to drive the grinder to separate from the top of the concrete along the length direction of the guide slide groove. By starting the dust suction pump and cooperating with the horn head, the debris generated by grinding the concrete surface can be sucked into the interior of the conical dust collecting barrel for collection, thereby effectively improving the practicality of the device.

[0017] Furthermore, a dust collecting groove is provided at the bottom of the conical dust collecting barrel, and an exhaust pipe is fixedly connected to the top of the conical dust collecting barrel.

[0018] By adopting the above technical solution and setting up the dust collecting trough and the exhaust pipe for use together, it is convenient to utilize the conical structure inside the conical dust collecting barrel to guide the heavier debris to slide into the dust collecting trough for collection, while the lighter air is discharged through the exhaust pipe, which effectively improves the practicality of the device.

[0019] Furthermore, the four corners of the bottom of the L-shaped base are fixedly connected with supporting feet, and the bottoms of the supporting feet are fixedly connected with rubber pads.

[0020] By adopting the above technical solution, by setting the supporting feet and the rubber pads for use together, a flexible contact is formed between the L-shaped base and the ground through the rubber pads, which reduces the wear between the L-shaped base and the ground and improves the installation stability of the L-shaped base.

[0021] In summary, this application has at least one of the following beneficial effects:

[0022] 1. By setting up the coordinated use of the jacking assembly and the drive assembly, it is convenient to use a grinder to grind the top of the concrete block placed on the top of the jacking platform. Then, by using the coordinated use of the transmission rack 1, the transmission gear, and the transmission rack 2, the grinder is driven away from the top of the concrete block, while the ultrasonic detector is driven to fit the polished flat surface of the top of the concrete block for detection, which effectively reduces the scattering and attenuation of ultrasonic signals caused by the uneven concrete surface, residual mortar and aggregate, and improves the detection accuracy of the device.

[0023] 2. By setting up the use of the dust suction pump and the horn head, when the follower slide is driven to drive the grinder to separate from the top of the concrete along the length direction of the guide chute, the dust suction pump is started to cooperate with the horn head to suck the debris generated by grinding the concrete surface into the interior of the conical dust collecting barrel for collection, thereby effectively improving the practicality of the device.

[0033] Moreover, the lifting assembly includes a lifting electric push rod 15 fixedly connected to one end of the L-shaped base 1, the output end of the lifting electric push rod 15 passes through the support platform 2 and is fixedly connected to the lifting platform 3, and the four corners of the bottom of the lifting platform 3 are fixedly connected with a guide slide 16, one end of the guide slide 16 passes through the support platform 2 and is slidably connected to the support platform 2;

[0034] Furthermore, a friction groove 17 is provided on the top of the lifting platform 3 .

[0035] When in use, first place the concrete block on the top of the lifting platform 3, and set the friction groove 17 to increase the friction between the lifting platform 3 and the concrete block, thereby improving the stability of the concrete block. Then, by starting the lifting electric push rod 15, the lifting platform 3 is pushed to drive the concrete block to move upward along the length direction of the guide slide rod 16, and the lifting electric push rod 15 pushes the concrete block to form a conflict with the output end of the grinder 12. At this time, the grinder 12 is started to grind the top of the concrete block, so that the top of the concrete block forms a flat surface that is compatible with the ultrasonic detector 6;

[0036] Then, the lifting electric push rod 15 is started in the reverse direction to cooperate with gravity to drive the lifting platform 3 to pull the concrete block along the length direction of the guide slide 16 to break away from the interference with the grinder 12. Then, the lifting motor 14 is started to drive the lifting screw 13 to rotate, and the lifting screw 13 is driven to form a threaded connection with the lifting slide 5, thereby driving the lifting slide 5 to move downward along the length direction of the lifting chute 4, and the lifting slide 5 drives the ultrasonic detector 6 to move closer to the concrete block;

[0038] Then, the lifting slide 5 drives the ultrasonic detector 6 to fit into the flat surface of the top of the concrete and detect the bubbles on the surface of the concrete. This facilitates the automatic grinding of one end of the concrete before driving the ultrasonic detector 6 to detect the bubbles on the surface of the concrete, effectively reducing the scattering and attenuation of ultrasonic signals caused by the uneven concrete surface, residual mortar and aggregate, and improving the detection accuracy of the device.

At the same time, the internal conical structure of the conical dust collecting barrel 20 is utilized to make the heavier debris spirally fall along the inner wall of the conical dust collecting barrel 20 and slide into the interior of the dust collecting trough 21 for collection, while the lighter air is discharged from the interior of the conical dust collecting barrel 20 through the exhaust pipe 22, thereby facilitating the automatic collection of debris generated by the grinding of the grinder 12, effectively improving the practicality of the device.

[0042] Reference Figure 1The four corners of the bottom of the L-shaped base 1 are fixedly connected with support feet 23, and the bottom of the support feet 23 is fixedly connected with a rubber pad 24.

[0043] During use, when the L-shaped base 1 is placed on the ground, by setting the support feet 23 and the rubber pads 24, a flexible resistance is formed between the L-shaped base 1 and the ground, thereby effectively reducing the wear between the L-shaped base 1 and the ground, and at the same time improving the installation stability of the L-shaped base 1.

Then, the lifting electric push rod 15 is started to push the lifting platform 3 to drive the concrete block to move upward along the length direction of the guide slide rod 16, and the lifting electric push rod 15 pushes the concrete block to form a conflict with the output end of the grinder 12. At this time, the grinder 12 is started to grind the top of the concrete block, so that the top of the concrete block forms a flat surface that is compatible with the ultrasonic detector 6.

[0045] Then, the lifting electric push rod 15 is started in the reverse direction to cooperate with gravity to drive the lifting platform 3 to pull the concrete block along the length direction of the guide slide 16 to break away from the conflict with the grinder 12, and then the lifting motor 14 is started to drive the lifting screw 13 to rotate, and drive the lifting screw 13 to form a threaded connection with the lifting slide 5, thereby driving the lifting slide 5 to move downward along the length direction of the lifting chute 4, and making the lifting slide 5 drive the ultrasonic detector 6 to move closer to the concrete block, and at the same time, the lifting slide 5 drives the transmission rack 1 7 to engage with the transmission gear 8, and drives the transmission gear 8 to rotate, and at the same time drives the transmission gear 8 to engage with the transmission rack 2 11, thereby pushing the transmission rack 2 11 to drive the follower slide 10 to move along the length direction of the guide chute 9, and making the follower slide 10 drive the grinder 12 to break away from the top of the concrete block;

[0046] When the follower slide 10 is driven to drive the grinder 12 to separate from the top of the concrete along the length direction of the guide chute 9, the dust suction pump 19 is started to cooperate with the horn head 18 to quickly collect the debris generated by grinding the concrete surface, so that the debris passes through the dust suction pump 19 and enters the interior of the conical dust collecting barrel 20. At the same time, the internal conical structure of the conical dust collecting barrel 20 is utilized to make the heavier debris spirally fall along the inner wall of the conical dust collecting barrel 20 and slide into the dust collecting trough 21 for collection, while the lighter air is discharged from the interior of the conical dust collecting barrel 20 through the exhaust pipe 22. Then, the lifting slide 5 drives the ultrasonic detector 6 to fit the flat surface of the concrete top and detect bubbles on the concrete surface.
