[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0030] like Figure 1-2As shown, a rapid inspection device for rubber rod holes in prefabricated box girders for high-speed railways is used to inspect the holes of prefabricated box girders 1. A rubber rod 2 is installed in the hole of the prefabricated box girder 1. The rubber rod 2 needs to be pulled out after the curing of the prefabricated box girder 1 is completed. The inspection device provided by the present application includes a first mounting seat 4 and a detection body 3, wherein one side of the first mounting seat 4 is connected to the end of the rubber rod 2 to be pulled out in a detachable manner. Specifically, the first mounting seat 4 is a disc or a flange, and its outer diameter is smaller than the outer diameter of the rubber rod 2, so that it can move in the hole of the prefabricated box girder 1 and be fixedly connected to the end face of the rubber rod 2 by bolts or glue.

[0031] The other side of the first mounting base 4 is connected to the detection body 3. The first mounting base 4 can be integrally formed with the detection body 3 or fixed in a detachable manner. The detection body 3 is a rod-shaped or columnar structure as a whole, and its outer peripheral surface is integrated with a searchlight 6, a video probe 7, an acoustic wave transmitting terminal 5, an acoustic wave receiving terminal 9 and an information storage module 11.

[0032] In an optional embodiment, the detection body 3 is a hollow polygonal structure made of rubber material, with a battery inside. A group of searchlights 6, video probes 7, sound wave transmitting terminals 5 and sound wave receiving terminals 9 are provided on any side of the detection body 3, so that the channel quality can be detected on different sides. The data detected by the sound wave receiving terminal 9 and the video probe 7 are stored through the information storage module 11, and the channel quality can be determined by later checking the stored data. The detection body 3 is set to be multi-faceted, and the channel defect position can be accurately determined based on the detection data from different sides.

[0033] In this embodiment, the detection body 3 is preferably a quadrangular prism, the circumscribed circle diameter of which is smaller than the diameter of the rubber rod 2 to be pulled out, thereby avoiding friction between the external components of the detection body 3 and the channel during the pulling process.

[0034] In an optional embodiment, the video probe 7, the sound wave transmitting terminal 5 and the sound wave receiving terminal 9 are correspondingly connected to the information storage module 11. Specifically, in this application, the connection and power supply of each module are carried out through a data transmission interface, which can be a USB interface or other types of fool-proof interfaces.

[0035] Specifically, the searchlight 6 is installed on the detection body 3 through a socket. The socket can be a rubber block, fixed to the detection body 3 by bolts or bonding. The socket includes two fixed blocks 13 distributed at intervals. The adjacent sides of the two fixed blocks 13 are provided with a first slot. The searchlight 6 is set on the fixed seat. The distance between the fixed seat and the two fixed blocks 13 is adapted. First blocks corresponding to the first slot are provided on both sides of the fixed seat. The first blocks and the first slot are slidably assembled. One end of the two fixed blocks 13 is connected as a closed end through a connecting part 12. The closed end is provided with a first interface. A first connector corresponding to the first interface is provided on the fixed seat. The first interface and the first connector are docked in the process of inserting the fixed block 13. The first interface extends to the inside of the detection body 3 through a connecting line and is connected to the battery through a circuit board.

[0036] The outer wall of the detection body 3 is provided with a mounting groove 8 close to the searchlight 6. The mounting groove 8 is used to install the video probe 7, so that the inner wall of the channel is illuminated by the searchlight 6, which is convenient for the video probe 7 to take video shots. The video probe 7 is inserted into the mounting groove 8 through the mounting base; a second interface corresponding to the mounting base is provided inside the mounting groove 8, and a second connector corresponding to the second interface is provided on the mounting base. The installation of the mounting groove 8 further reduces the length of the video probe 7 extending from the outer wall of the detection body 3, thereby ensuring the safety of the video probe 7 to the greatest extent. The second interface extends to the interior of the detection body 3 through a connecting line and is connected to the battery through a circuit board.

[0037] An information storage module 11 is located on the end face of the detection body 3, away from the first mounting base 4. A second mounting base 10 is mounted on the information storage module 11, aligning with the inscribed circle of the detection body 3 and securely attached to the detection body 3 via bolts. A third interface is provided at the end of the detection body 3, and a third connector corresponding to the third interface is provided on the second mounting base 10. This third interface extends into the interior of the detection body 3 via a connecting cable and is connected to the battery via a circuit board.

[0038] Furthermore, the sound wave transmitting terminal 5 is arranged at the end of the detection body 3 close to the first mounting seat 4, and the sound wave receiving terminal 9 is arranged at the end of the detection body 3 away from the first mounting seat 4. The sound wave transmitting terminal 5 will emit sound waves into the channel for flaw detection, and then the sound wave receiving terminal 9 will transmit the sound waves that bounce back after touching the channel to the information storage module 11 for storage.

[0039] The detection body 3 is provided with a fourth interface corresponding to the sound wave transmitting terminal 5, and the sound wave transmitting terminal 5 is provided with a fourth connector corresponding to the fourth interface. The fourth interface extends to the inside of the detection body 3 through a connecting line and is connected to the battery through a circuit board.

[0040] The detection body 3 is provided with a fifth interface corresponding to the sound wave receiving terminal 9, and the sound wave receiving terminal 9 is provided with a fifth connector corresponding to the fifth interface. The fifth interface extends to the inside of the detection body 3 through a connecting line and is connected to the battery through a circuit board.

[0041] During specific use, as the pulling detection body 3 of the rubber rod 2 passes through the hole completely, the video probe 7 will perform high-definition holographic recording on the inner wall of the hole. At this time, the sound wave transmitting end 5 will emit sound waves to the inner wall of the extraction hole for flaw detection, and then the sound wave receiving end 9 will recover the sound waves that touch the inner wall of the extraction hole and bounce back. The recovered sound waves are stored in the information storage module 11. When the rubber rod 2 is completely pulled out, the searchlight 6, video probe 7, sound wave transmitting end 5 and sound wave receiving end 9 stop working. At this time, the extraction device can be removed from the rubber rod 2, and then the information storage module 11 can be removed. Then the information storage module 11 can be plugged into a designated reading device (PC end) for comparison with the qualified corrugation. At the same time, the video screen can be carefully observed for the hole wall. At the same time, the specific location of the gap, hidden injury or unqualified place can be calculated according to the extraction speed and the length of the extraction hole, so that the workers can remedy it in time.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
