Description

Technical Field

[0001] The utility model relates to the technical field of detectors, in particular to a portable non-destructive detector. Background Art

[0002] The ultrasonic detection method is a commonly used method in concrete detection. The ultrasonic detection method mainly detects whether there are holes and non-compactness inside the concrete, and it is a detection parameter in the entity detection of concrete structures.

[0003] When the existing ultrasonic detector detects concrete, it is necessary to keep the detection surface of the concrete flat. Generally, small grinding equipment needs to be prepared to grind the wall surface, which increases the number of equipment that operators need to carry during the detection operation, indirectly increasing the burden on the detection personnel. In addition, a coupling agent is required between the transducer and the detection surface to maintain a tight bond, and the coupling layer cannot be doped with air or sediment. When the existing transducer contacts the detection surface, the contact process is exposed to the external environment, greatly increasing the probability of sediment entering the coupling layer. Therefore, a portable non-destructive detector is proposed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that in the prior art, small grinding equipment generally needs to be prepared to grind the wall surface, which increases the number of equipment that operators need to carry during the detection operation and indirectly increases the burden on the detection personnel, and to propose a portable non-destructive detector.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

A driven conical gear ring is rotatably arranged on the surface of the transducer. A driving component for driving the driven conical gear ring to rotate is arranged on the surface of the transducer. A telescopic sleeve rod is rotatably arranged on the surface of the driven conical gear ring through a damping rotating shaft. A sliding rod is slidably connected inside the telescopic sleeve rod. One end of the sliding rod is fixedly connected with a grinding disc. A sealing folding cover is fixedly connected to the bottom end of the driven conical gear ring. A rubber ring is fixedly connected to the bottom end of the sealing folding cover.

[0007] Preferably, the driving component includes a motor box fixedly connected to the side wall of the ultrasonic detector body through an L-shaped connecting rod and a servo motor arranged inside the motor box. The output end of the servo motor is fixedly connected with a driving conical gear meshing with the driven conical gear ring.

[0008] Preferably, a pressing spring is fixedly connected between one end of the sliding rod and the inner wall of the telescopic sleeve rod. A telescopic rod is fixedly connected to the side wall of the telescopic sleeve rod, and a suction cup is fixedly connected to one end of the telescopic rod.

[0009] Preferably, a plurality of exhaust grooves are formed at the bottom end of the rubber ring.

[0010] Preferably, a plurality of convex grinding lines are arranged on the grinding surface of the grinding disc.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. In this solution, by providing a driving component, a driven conical tooth ring and a grinding disc, the driving component is used to drive the driven conical tooth ring to rotate, and then drive the grinding disc to rotate, so as to realize the function of grinding the concrete detection surface. Without the need to rely on special grinding equipment, it is convenient for detection operations and indirectly reduces the work burden of detection personnel.

[0013] 2. In this solution, by providing a sealing folding cover, a rubber ring, a telescopic rod and a suction cup, the sealing folding cover and the rubber ring can make the coupling agent in a closed state when contacting the concrete detection surface. When the sealing folding cover is compressed, the air inside it is discharged through the exhaust grooves at the bottom of the rubber ring, so as to discharge the dust remaining inside the sealing folding cover, and at the same time play a role in isolating external dust, reducing the probability of sediment entering the coupling layer.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Refer to Figures 1-5 , a portable non-destructive detector, including an ultrasonic detector body 1 and a transducer 2 connected to the ultrasonic detector body 1. A driven conical gear ring 6 is rotatably arranged on the surface of the transducer 2. A driving component for driving the driven conical gear ring 6 to rotate is arranged on the surface of the transducer 2. A telescopic sleeve rod 5 is rotatably arranged on the surface of the driven conical gear ring 6 through a damping rotating shaft. A sliding rod 10 is slidably connected inside the telescopic sleeve rod 5. One end of the sliding rod 10 is fixedly connected to a grinding disc 4. A plurality of raised grinding lines are arranged on the grinding surface of the grinding disc 4; A pressing spring 9 is fixedly connected between one end of the sliding rod 10 and the inner wall of the telescopic sleeve rod 5. A telescopic rod is fixedly connected to the side wall of the telescopic sleeve rod 5, and one end of the telescopic rod is fixedly connected to a suction cup 7.

[0022] It should be noted that: the driving component drives the driven conical gear ring 6 to rotate, and then drives the grinding disc 4 to rotate, which can flatten the detection surface of the concrete. Without the need to rely on other tools, it is convenient for the detection operation and indirectly reduces the workload of the detection personnel;

[0023] It is worth noting that: the raised grinding lines can help the grinding disc 4 quickly flatten the protrusions on the concrete detection surface and improve the flattening efficiency;

[0024] It is worth noting that: the pressing spring 9 cooperates with the sliding rod 10. When the pressing spring 9 is compressed by extrusion, under the elastic force of the pressing spring 9, the extrusion force between the grinding disc 4 and the detection surface can be greatly increased; At the same time, under the action of the telescopic sleeve rod 5, the sliding rod 10 can increase the distance between the grinding disc 4 and the transducer 2, which is convenient for flipping the grinding disc 4 to one side.

[0025] It is worth noting that: the suction cup 7 can play a certain supporting role for the transducer 2 and reduce the force required for the detection personnel to support the transducer 2.

[0026] A sealing folding cover 3 is fixedly connected to the bottom end of the driven conical gear ring 6. A rubber ring 8 is fixedly connected to the bottom end of the sealing folding cover 3, and a plurality of exhaust grooves are formed in the bottom end of the rubber ring 8.

[0027] It should be noted that when the sealing folding cover 3 is squeezed, the air inside it will be discharged through the exhaust grooves, and the dust and sediment inside the sealing folding cover 3 can be discharged together, reducing the amount of dust and sediment inside the sealing folding cover 3 while isolating the dust and sediment from the outside, greatly reducing the probability of dust and sediment entering the coupling layer.

[0028] The driving assembly includes a motor box 13 fixedly connected to the side wall of the ultrasonic detector body 1 through an L-shaped connecting rod 12 and a servo motor arranged inside the motor box 13. The output end of the servo motor is fixedly connected to a driving conical gear 11 that meshes with the driven conical gear ring 6.

[0029] It should be noted that the servo motor drives the driving conical gear 11 to rotate, and then drives the driven conical gear ring 6 to rotate. The driven conical gear ring 6 drives the grinding disc 4 to rotate through the telescopic sleeve rod 5 and the sliding rod 10, realizing the grinding function of the concrete detection surface.

[0030] The servo motor is a prior art, and its model is JB5274-91. It can realize the function of driving the driving conical gear 11 to rotate, and will not be elaborated here.

[0031] When the present utility model is in use, the grinding disc 4 is rotated in front of the transducer 2, and the servo motor is turned on. The servo motor drives the driven conical gear ring 6 to rotate through the driving conical gear 11, and then drives the grinding disc 4 to rotate through the telescopic sleeve rod 5 and the sliding rod 10, which can realize the leveling function of the concrete detection surface. Without the need to rely on special grinding equipment, it facilitates the detection operation and indirectly reduces the workload of the detection personnel;

[0032] Then the grinding disc 4 is flipped to one side, the coupling agent is applied to the surface of the transducer 2, and then the rubber ring 8 is made to contact the detection surface. The coupling agent is covered and isolated by the sealing folding cover 3, and then the contact operation between the coupling agent and the detection surface is carried out. During the contact process, the sealing folding cover 3 is squeezed, and the air inside it will be discharged through the exhaust grooves, and the dust and sediment inside the sealing folding cover 3 can be discharged together, reducing the amount of dust and sediment inside the sealing folding cover 3 while isolating the dust and sediment from the outside, greatly reducing the probability of dust and sediment entering the coupling layer.

[0033] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
