Description

[0002] With the acceleration of urbanization, the construction of infrastructure such as bridges and high-rise buildings has flourished. Precast beams, as key load-bearing components, have increasingly stringent quality requirements. During the research and development stage of precast beams, traditional strength testing methods have shown signs of fatigue and are unable to meet the testing requirements for high-quality products.

[0003] At present, traditional rebound testing is commonplace. The surface of the beam is tapped lightly with a rebound hammer, and the strength is estimated by the rebound value. However, the operation has significant disadvantages. Human factors such as uneven force, measurement point position deviation, and rebound angle inaccuracy seriously interfere with the accuracy of the rebound data, resulting in large fluctuations in the results and questionable credibility. Although the core drilling method can intuitively obtain core samples for strength measurement, drilling holes in the beam body to take cores will destroy the integrity of the overall structure.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1-Figure 8As shown, a prefabricated beam strength detection device provided by an embodiment of the present invention includes a base 101, a telescopic cylinder 102 is fixedly arranged on the upper surface of the base 101, and a mounting frame 103 is fixedly arranged at the telescopic end of the telescopic cylinder 102, and a fixing opening 104 is provided on the upper and lower surfaces of the mounting frame 103, and a displacement plate 105 is movably arranged in the mounting frame 103, and a mounting opening is provided on the outer wall of the displacement plate 105, and a telescopic cylinder 106 is fixedly arranged in the mounting opening, and a mounting plate 107 is fixedly arranged at the telescopic end of the telescopic cylinder 106, and an ultrasonic transducer 10 is arranged below the mounting plate 107. 8. The ultrasonic transducer 108 includes a transmitting transducer and a receiving transducer. A universal wheel 109 is fixedly provided on the lower surface of the base 101. The base 101 also includes: a connecting mechanism, which is arranged between the mounting plate 107 and the ultrasonic transducer 108, and is used to connect the mounting plate 107 and the ultrasonic transducer 108, and enable the ultrasonic transducer 108 to apply a constant pressure to the surface of the prefabricated beam; a displacement mechanism, which is arranged in the mounting frame 103, and is used to drive the displacement plate 105 to move in a horizontal position; a limiting mechanism, which is arranged on the outside of the mounting frame 103, and is used to promote stability between the mounting frame 103 and the prefabricated beam.

[0029] The two ends of the prefabricated beam to be inspected can be suspended in the air by means of erection, and then the installation frame 103 is placed at a suitable position on the outside of the prefabricated beam to be inspected by moving the base 101, and the installation frame 103 is driven to move up and down by the telescopic cylinder 102, so that the prefabricated beam is kept in the center position in the installation frame 103, and before the inspection, the prefabricated beam can be clamped by the limiting mechanism on the outside of the installation frame 103, so that the installation frame 103 and the prefabricated beam can be kept relatively stable, so that the inspection is more accurate, and then the position of the displacement plate 105 on the outside of the prefabricated beam can be flexibly adjusted by the displacement mechanism. When the displacement plate 105 is adjusted to a suitable position, the installation plate 107 can be driven to move by the telescopic cylinder 106, and the installation plate 107 drives the ultrasonic transducer 108 to move through the connecting mechanism, so that the ultrasonic transducer 108 and the measuring point arranged on the outer wall of the prefabricated beam are fitted together, and the transmitting transducer in the ultrasonic transducer 108 emits ultrasonic waves, which pass through the prefabricated beam. After internal propagation, it is received by the receiving transducer in another group of ultrasonic transducers 108. By moving the ultrasonic transducer 108 to different measuring points and repeating the above operation, multiple groups of data can be collected to obtain information at different positions inside the concrete. At the same time, by performing ultrasonic testing on precast beams of known strength, wave velocity data is obtained, and a compressive strength test is performed to obtain the corresponding strength value, and a relationship curve is established between the wave velocity and the compressive strength. The wave velocity of the precast beam obtained in the actual test is substituted into the relationship curve, and the strength of the concrete can be calculated. Compared with traditional testing equipment, the above-mentioned testing device does not need to transfer the precast beam to the testing equipment for testing, and can realize on-site testing of the precast beam. At the same time, multiple groups of mounting frames 103 can be used in combination. When the precast beam is long and the measuring points are far apart, the detection operation can also be performed. Furthermore, this detection method will not cause damage to the surface of the precast beam, will not affect the subsequent normal use of the precast beam, and has a better use effect.

[0030] As an embodiment of the present invention, please refer to Figure 4 and Figure 5The connecting mechanism includes a fixed rod 201 fixedly arranged on the outer wall of the mounting plate 107, and a movable plate 202 is fixedly arranged at the end of the fixed rod 201, and a vertical rod 203 is movably arranged on the outer wall of the movable plate 202, and a baffle 204 is fixedly arranged on the end of the vertical rod 203 close to the mounting plate 107, and a support plate 207 is fixedly arranged on the end of the vertical rod 203 away from the mounting plate 107, and the ultrasonic transducer 108 is fixedly arranged on the outer wall of the support plate 207, and a first spring 205 is sleeved on the outer side of the vertical rod 203, one end of the first spring 205 is connected to the outer wall of the movable plate 202, and the other end of the first spring 205 is connected to the baffle 204, and an adhesive component is also arranged on the outer side of the movable plate 202, which is used for bonding the ultrasonic transducer 108 between the ultrasonic transducer 108 and the prefabricated beam before the ultrasonic transducer 108 is bonded to the surface of the prefabricated beam. When the ultrasonic transducer 108 needs to be fitted with the surface of the prefabricated beam for detection, the mounting plate 107 can be driven close to the prefabricated beam by the telescopic cylinder 106. When the ultrasonic transducer 108 is fitted with the surface of the prefabricated beam, as the mounting plate 107 moves further, the movable plate 202 will be prompted to slide on the outside of the vertical rod 203, so that the first spring 205 is stretched until the touch switch 206 on the outer wall of the mounting plate 107 contacts the baffle 204, which will prompt the telescopic cylinder 106 to stop stretching and ensure that the first spring 205 maintains a constant stretching amount, thereby allowing the ultrasonic transducer 108 to apply a constant resisting force to the surface of the prefabricated beam, ensuring that the ultrasonic transducer 108 is stably fitted with the prefabricated beam while avoiding damage to the ultrasonic transducer 108 and the surface of the prefabricated beam, thereby achieving a better use effect.

[0031] As an embodiment of the present invention, please refer to Figure 4 and Figure 5The bonding component includes a coupling agent replenisher 301 fixedly arranged on the outer wall of the movable plate 202, a hose 302 is connected to the material guide end of the coupling agent replenisher 301, a storage box 303 is fixedly arranged on the outer wall of the support plate 207, and the end of the hose 302 is connected to the storage box 303, and the outer wall of the storage box 303 is connected to equidistantly distributed agent guide tubes 304, and the agent guide tubes 304 are located on both sides of the ultrasonic transducer 108. A trigger component is also provided on the support plate 207, which is used to replenish the coupling agent in time before the ultrasonic transducer 108 is about to be attached to the prefabricated beam. When the ultrasonic transducer 108 is about to approach the prefabricated beam, the trigger component is triggered. Under the action of the component, the coupling agent replenisher 301 can be prompted to introduce a proper amount of coupling agent into the agent storage box 303 through the hose 302, and then sprayed to the measuring point on the surface of the prefabricated beam through the agent guide tube 304. In this way, when the ultrasonic transducer 108 is in contact with the prefabricated beam, the coupling agent can play a role in bonding the prefabricated beam and the ultrasonic transducer 108, ensuring that the ultrasonic transducer 108 is well coupled with the surface of the prefabricated beam. The coupling agent usually uses butter, vaseline, paste and other coupling agents to reduce the air gap between the transducer and the surface of the prefabricated beam, so that the ultrasonic wave can be effectively transmitted into and out of the prefabricated beam, making the detection result more accurate and the use effect better.

[0032] As an embodiment of the present invention, please refer to Figure 4 and Figure 5 The trigger assembly includes a lever 401, a through hole is formed on the outer wall of the support plate 207, and the lever 401 is movably arranged in the through hole, a square frame 402 is fixedly arranged on one end of the lever 401 close to the mounting plate 107, a second spring 403 is sleeved on the outer side of the lever 401, one end of the first spring 205 is connected to the square frame 402, and the other end of the first spring 205 is connected to the outer wall of the support plate 207, a support rod 404 is fixedly arranged on the outer wall of the support plate 207 close to the square frame 402, and the end of the support rod 404 is fixedly arranged on the outer wall of the support plate 207 A touch switch 405 is fixedly provided at the bottom, and the touch switch 405 is located below the frame 402. When the ultrasonic transducer 108 gradually approaches the prefabricated beam, the push rod 401 will first contact the surface of the prefabricated beam. As the ultrasonic transducer 108 continues to move, the push rod 401 will lift the frame 402 and stretch the second spring 403. At this time, the frame 402 will leave the touch switch 405, and the adhesive component can be automatically triggered to supplement the coupling agent between the ultrasonic transducer 108 and the prefabricated beam, thereby achieving a better use effect.

[0033] As an embodiment of the present invention, please refer to Figure 3 and Figure 8The displacement mechanism includes an electric slide rail 501 fixedly arranged in the installation frame 103, and a first slider 502 is slidably arranged in the electric slide rail 501, a surrounding frame 503 is fixedly arranged between adjacent first sliders 502, and an electric slide rail 504 is fixedly arranged on the inner wall of the surrounding frame 503, a second slider 505 is slidably arranged in the electric slide rail 504, and the displacement plate 105 is fixedly arranged between adjacent second sliders 505, and the surrounding frame 503 can be moved forward and backward by sliding the first slider 502 in the electric slide rail 501, and the displacement plate 105 can be moved left and right by sliding the second slider 505 in the electric slide rail 504, so that the horizontal position of the displacement plate 105 can be flexibly adjusted, and the use effect is better.

When the precast beam is located in the installation frame 103, the lifting plate 603 can be driven to move by the telescopic cylinder three 602, and the clamping plate 607 can be driven to move together by the connecting component on the outer side of the lifting plate 603, so as to play the role of clamping the precast beam, so that the ultrasonic transducer 108 and the precast beam remain relatively stable during the detection process, the detection is more accurate, and the use effect is better.

[0035] As an embodiment of the present invention, please refer to Figure 7 The connecting assembly includes a telescopic rod 604 fixedly arranged on the outer wall of the clamping plate 607, and the telescopic rod 604 penetrates the lifting plate 603, and a baffle 605 is fixedly arranged at the end of the telescopic rod 604.

When the rubber gasket 608 on the outer wall of the clamp plate 607 contacts the surface of the precast beam, as the lifting plate 603 moves further, the third spring 606 on the outside of the telescopic rod 604 will be stretched until the lifting plate 603 contacts the touch switch 3 609 on the surface of the clamp plate 607, which will prompt the telescopic cylinder 3 602 to stop extending and retracting, so that the clamp plate 607 applies a moderate clamping force to the precast beam, ensuring stable clamping while avoiding damage to the surface of the precast beam, and achieving better use effect.

[0036] When in use, the two ends of the prefabricated beam to be inspected can be suspended in the air by means of erection, and then the mounting frame 103 is placed at a suitable position on the outside of the prefabricated beam to be inspected by moving the base 101, and the mounting frame 103 is driven to move up and down by the telescopic cylinder 102, so that the prefabricated beam is kept in the center position in the mounting frame 103, and before the inspection, the prefabricated beam can be clamped by the limiting mechanism on the outside of the mounting frame 103, so that the mounting frame 103 and the prefabricated beam can be kept relatively stable, so that the inspection is more accurate, and then the position of the displacement plate 105 on the outside of the prefabricated beam can be flexibly adjusted by the displacement mechanism. When the displacement plate 105 is adjusted to a suitable position, the mounting plate 107 can be driven to move by the telescopic cylinder 106, and the mounting plate 107 drives the ultrasonic transducer 108 to move through the connecting mechanism, so that the ultrasonic transducer 108 and the measuring point arranged on the outer wall of the prefabricated beam are fitted together, and the transmitting transducer in the ultrasonic transducer 108 emits ultrasonic waves, which are passed through the prefabricated beam.

At the same time, by performing ultrasonic testing on prefabricated beams of known strength, wave velocity data is obtained, and a compressive strength test is performed to obtain the corresponding strength value, and a relationship curve is established between the wave velocity and the compressive strength. The wave velocity of the prefabricated beam obtained in the actual test is substituted into the relationship curve, and the strength of the concrete can be calculated. Compared with traditional testing equipment, the above-mentioned testing device does not need to transfer the prefabricated beam to the testing equipment for testing, and can realize on-site testing of the prefabricated beam. At the same time, multiple groups of mounting frames 103 can be used in combination. When the prefabricated beam is long and the measuring points are far apart, the detection operation can also be performed. Furthermore, this detection method will not cause damage to the surface of the prefabricated beam, will not affect the subsequent normal use of the prefabricated beam, and has a better use effect.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
