Description

Technical Field

[0001] The invention relates to the technical field of concrete detection, and in particular to a prefabricated concrete part strength detection device. Background Art

[0002] Concrete is one of the most important civil engineering materials in contemporary times. Concrete products produced in a standardized and mechanized manner in a factory are called precast concrete parts. Precast parts can be manufactured in advance in the factory and then transported to the site for installation, which greatly shortens the construction period. However, after production, strength testing devices are required to test the strength of precast part samples. Strength testing devices are an important tool to ensure the quality of precast parts.

Two groups of bearing plates are provided above the detection table, and the bearing plates are slidably connected to the detection table. The bearing plates are placed above the rollers and contact the rollers. The bearing plates are slidably connected to the detection table, and the friction between the bearing plates and the detection table can be reduced by the rollers. The precast component is placed on the bearing plates and can adjust its position on the detection table. By using the bearing platform to drive the prefabricated component to move on the testing platform, the force application point of the pressure plate on the prefabricated component can be changed, and the strength test of different positions of the prefabricated component can be carried out more conveniently.

[0033] like Figures 1 to 8 As shown, the strength testing equipment for precast concrete parts comprises a testing platform 1, the top of the testing platform 1 is fixedly connected with a gantry 2, the top of the gantry 2 is provided with a hydraulic cylinder 3, the driving end of the hydraulic cylinder 3 is fixedly connected with a pressure testing plate 4, the upper part of the testing platform 1 is provided with a protective component, the interior of the testing platform 1 is provided with a positioning component, the middle part of the testing platform 1 is provided with a placement groove 9, the interior of the placement groove 9 is provided with a cleaning component, the upper part of the cleaning component is provided with an air blowing component, the protective component is arranged around the placement groove 9, the positioning component is arranged on both sides of the inner wall of the placement groove 9, and the cleaning component is used in conjunction with the air blowing component;

[0034] The concrete prefabricated part to be inspected is placed in the placement groove 9, and the positioning component is used to clamp and position the prefabricated part. The surface of the prefabricated part can be fitted to achieve the purpose of clamping the prefabricated part, which is convenient for clamping and positioning concrete prefabricated parts of different shapes. Then, during the downward pressing process, the protective component will be driven to operate, and the surrounding areas of the placement groove 9 will be enclosed to achieve a protective effect. After the inspection is completed, the broken concrete prefabricated fragments will be cleaned up first, and then the cleaning component and the blowing component will be used to clean the remaining broken sand and dust.

[0035] like Figure 2 and Figure 3As shown, the protection component includes a long rod 501 fixedly connected to the side of the pressure detection plate 4, a sliding groove 502 is provided on the inner wall of the side of the gantry 2, and the long rod 501 slides in the sliding groove 502, and the outer surface of the long rod 501 is hinged with an inclined rod 503, and the end of the inclined rod 503 away from the long rod 501 is hinged with a side plate 504, and the upper surface of the detection platform 1 is provided with a limiting groove 506, and the bottom end of the side plate 504 is fixedly connected to a limiting base 505, and the limiting base 505 slides inside the limiting groove 506, and the front and rear sides of the detection platform 1 are provided with a shaft rod 508, and the outer surface of the shaft rod 508 is fixedly connected with a flap 809, and the end of the shaft rod 508 is provided with a gear 1 510, and the end of the limiting base 505 is fixedly connected with a rack 1 507, and the rack 1 507 is meshed with the gear 1 510.

[0036] During the downward movement of the pressure detection plate 4, the long rod 501 will be driven to slide in the slide groove 502. During the downward movement of the long rod 501, the inclined bar will be driven to push the side plate 504 to move to both sides. During the movement of the limit base 505, the rack 507 will be driven to move. After the rack 507 is meshed with the gear 510, the gear 510 will be driven to rotate, and then the shaft 508 will be driven to rotate. The flap 809 will flip 180 degrees as the shaft 508 rotates, so that the side plate 504 and the flap 809 form a baffle around the placement groove 9, which has a protective effect. It can block the fragments of the concrete prefabricated parts that are broken and splashed during the detection process, avoid the fragments from hitting the staff or machinery, and improve the safety during the detection process.

[0037] like Figure 4 and Figure 5 As shown, the positioning assembly includes a rocking plate 601 arranged on the side of the detection platform 1, a transmission rod 602 is fixedly connected to the middle of the rocking plate 601, and one end of the transmission rod 602 extending into the interior of the detection platform 1 is fixedly connected to the second gear 603, and a folding rod 605 is movably arranged inside the detection platform 1, one end of the folding rod 605 is fixedly connected to the second rack 604, and the second rack 604 is meshed and connected with the second gear 603, and the other end of the folding rod 605 is fixedly connected to a clamping plate 606, and a sliding rod 607 is movably interspersed in the middle of the clamping plate 606, and the outer surface of the sliding rod 607 is sleeved with a spring 1 608, and the end of the sliding rod 607 away from the clamping plate 606 is hinged with an arc block 609;

[0038] The rotating oscillating plate 601 drives the gear 2 603 to rotate through the transmission rod 602. The rotation of the gear 2 603 drives the rack 2 604 on the upper and lower sides to move toward each other, which will then drive the clamping plate 606 to move toward the concrete prefabricated part. The arc block 609 on the side of the clamping plate 606 will first abut against the outer surface of the concrete prefabricated part. As the clamping plate 606 continues to advance, the arc block 609 will push the sliding rod 607 and the clamping plate 606 to slide and squeeze the spring 2 807 after abutment. Each arc block 609 can fit the surface of the prefabricated part to achieve the purpose of clamping the prefabricated part, thereby improving the adaptability of the positioning component and facilitating the clamping and positioning of concrete prefabricated parts of different shapes. Moreover, under the push of the clamping plate 606, the prefabricated part can be stably clamped in the middle of the placement groove 9, so that when the pressure detection plate 4 squeezes the prefabricated part, the prefabricated part is directly below the pressure detection plate 4, thereby ensuring the accuracy of the detection.

[0039] like Figure 6 and Figure 7 As shown, the cleaning assembly includes a motor 701 arranged inside the detection table 1, the driving end of the motor 701 is fixedly connected to a turntable 702, the upper surface edge of the turntable 702 is fixedly connected to a lever 703, the outer surface of the lever 703 is sleeved with a frame plate 704, the side of the frame plate 704 is fixedly connected to a push plate 705, and the end of the push plate 705 away from the frame plate 704 is fixedly connected to a cleaning brush 706, a positioning plate 707 is arranged inside the detection table 1, the positioning plate 707 is movably interspersed on the lower surface of the push plate 705, the cleaning brush 706 is arranged on the side of the placement groove 9, and a sewage outlet 708 is opened through the inner wall edge of the bottom end of the placement groove 9;

[0040] The motor 701 drives the turntable 702 to rotate and drives the lever 703 to rotate around the center of the turntable 702. During the rotation, the lever 703 pushes the frame plate 704 to make a linear reciprocating motion. The frame plate 704 and the cleaning brush 706 are connected by a push plate 705, and the push plate 705 is limited by the positioning plate 707. Then, the frame plate 704 pushes the cleaning brush 706 to move during the movement. The cleaning brush 706 moves back and forth with the frame plate 704 and cleans the placement slot 9.

[0041] like Figure 6 and Figure 8As shown, the air blowing assembly includes an air bag 801 arranged inside the test bench 1, a side of the air bag 801 away from the frame plate 704 is fixedly connected with a bellows 802, an end of the bellows 802 away from the air bag 801 is fixedly connected with an air pipe 803, an outer surface of the air pipe 803 is provided with air nozzles 804 distributed in a linear matrix, the air pipe 803 is fixedly connected to the top of the cleaning brush 706, the air nozzle 804 is inclined downward at forty-five degrees, both sides of the top of the air bag 801 are fixedly connected with T-shaped rods 806, the side of the T-shaped rod 806 is fixedly connected with a spring 2 807, a T-shaped slot 805 is provided inside the test bench 1, and the T-shaped rod 806 slides in the T-shaped slot 805;

[0042] The frame plate 704 will squeeze the airbag 801 during the movement. After the airbag 801 is squeezed, the air inside will enter the air pipe 803 from the bellows 802 and be ejected from the air nozzle 804, which can blow away the dust in the placement groove 9. The air pipe 803 is fixed to the top of the cleaning brush 706, so that the blowing effect can be added during the cleaning process, and the dust that the cleaning brush 706 cannot clean can be blown away.

[0043] The technical solution provided by the present invention is to place the concrete prefabricated part to be tested into the placement groove 9, start the hydraulic cylinder 3 to push the pressure detection plate 4 to extrude the concrete prefabricated part, so as to achieve the purpose of testing the strength of the concrete prefabricated part. When the concrete prefabricated part is placed before the test, the rotating oscillating plate 601 drives the gear 2 603 to rotate through the transmission rod 602, and the gear 2 603 is meshed with the rack 2 604 on the upper and lower sides, and then during the rotation process, the rack 2 604 on the upper and lower sides will be driven to move toward each other, and the other end of the rack 2 604 is fixed to the splint 606 through the folding rod 605, and then the splint 606 will be driven to move toward the direction of the concrete prefabricated part, and the arc block 609 on the side of the splint 606 will first abut against the concrete prefabricated part. As the clamping plate 606 continues to advance, the arc block 609 will push the slide bar 607 and the clamping plate 606 to slide and squeeze the spring 807 after abutting against the outer surface of the prefabricated part. Since each arc block 609 is independent and the arc block 609 and the slide bar 607 are directly hinged, each arc block 609 can fit the surface of the prefabricated part to achieve the purpose of clamping the prefabricated part, thereby improving the adaptability of the positioning component, facilitating the clamping and positioning of concrete prefabricated parts of different shapes, and under the push of the clamping plate 606, the prefabricated part can be stably clamped in the middle of the placement groove 9, so that when the pressure detection plate 4 squeezes the prefabricated part, the prefabricated part is directly below the pressure detection plate 4, thereby ensuring the accuracy of the detection;

[0044] After the concrete prefabricated part is clamped and positioned, the hydraulic cylinder 3 is started to push the pressure detection plate 4 to squeeze the concrete prefabricated part. During the downward movement of the pressure detection plate 4, the long rod 501 is driven to slide in the slide groove 502. During the downward movement of the long rod 501, the inclined bar is driven to push the side plate 504 to move to both sides. Since the bottom of the side plate 504 slides in the limit groove 506 through the limit base 505, the side plate 504 can be positioned to ensure that the side plate 504 moves in a straight line. During the movement of the limit base 505, The rack 507 is driven to move, and after the rack 507 is meshed with the gear 510, the gear 510 is driven to rotate, and then the shaft 508 is driven to rotate. The flap 809 is turned 180 degrees with the rotation of the shaft 508, so that the side plate 504 and the flap 809 are formed around the placement groove 9 to form a baffle, which plays a protective role and can block the fragments of the concrete prefabricated parts that are broken and splashed during the inspection process, so as to prevent the fragments from hitting the staff or machinery, thereby improving the safety during the inspection process;

[0045] After the inspection is completed, the broken concrete prefabricated parts are cleaned up. At this time, there are still small pieces of sand and dust in the placement groove 9 that are inconvenient to clean. The motor 701 is started, and the motor 701 drives the turntable 702 to rotate and drives the lever 703 to rotate around the center of the turntable 702. The lever 703 will push the frame plate 704 to make a linear reciprocating motion during the rotation. The frame plate 704 and the cleaning brush 706 are connected by a push plate 705, and the push plate 705 is limited by the positioning plate 707, so that the frame plate 704 will push the cleaning brush 706 to move during the movement. The cleaning brush 706 moves back and forth with the frame plate 704 and cleans the placement groove 9. At the same time, the frame plate 704 will squeeze the air bag 801 during the movement. After the air bag 801 is squeezed, the air inside will be discharged from the corrugated board. The tube 802 enters the air pipe 803 and is sprayed out from the air nozzle 804, which can blow away the dust in the placement groove 9, and the air pipe 803 is fixed at the top of the cleaning brush 706, so that the blowing effect can be added during the cleaning process, and the dust that the cleaning brush 706 cannot clean can be blown away. During the extrusion process of the air bag 801, the T-bar 806 will slide in the T-slot 805 and squeeze the spring 2 807. When the frame plate 704 starts to move back, the spring 2 807 rebounds and drives the air bag 801 to recover, thereby achieving the effect of reciprocating blowing. The cleaning component and the blowing component work together to clean the placement groove 9, and clean the broken sand and dust into the drain outlet 708 at the same time and discharge them, thereby achieving the effect of quickly removing the broken sand and dust, and avoiding affecting the subsequent prefabricated part inspection.
