Description

Technical Field

[0001] This utility model relates to the field of steel components, and in particular to a flaw detection and testing device for steel components. Background Technology

[0002] A steel component flaw detection device is a device used to detect internal defects in steel components. It mainly uses methods such as ultrasonic waves, magnetic particles, penetrant testing, or X-rays to detect whether there are internal defects such as cracks, pores, slag inclusions, and lack of fusion without compromising the performance of the steel components. This device is crucial for ensuring the material and welding quality of steel components and is an indispensable inspection method in steel structure engineering.

[0003] Existing steel component flaw detection devices lack a structure for evenly applying coupling agent. When coupling agent is needed, it cannot be evenly applied using the device's built-in structure; a separate brush is required, which is inconvenient and time-consuming.

[0004] Therefore, to address the problem that existing steel component flaw detection devices lack a structure for uniformly applying couplant, requiring a separate brush for application and causing inconvenience and time consumption, a new steel component flaw detection device can be designed. This device incorporates a mounting slot for the drive motor, reducing the overall footprint. During operation, the drive motor's output drives the active gear, which in turn rotates the main brush head synchronously. This facilitates the uniform application of couplant to the steel component surface during flaw detection. Utility Model Content

[0005] To overcome the problem that existing steel component flaw detection devices do not have a structure for uniformly applying coupling agent, and require a separate brush to spread the agent evenly when needed, which is inconvenient and time-consuming.

[0006] The technical solution of this utility model is as follows: a steel component flaw detection device, including a flaw detector body; it also includes a mounting groove, a drive motor, a transmission shaft, a drive gear, and a main brush head. One end of a cable is provided on the right side surface of the flaw detector body, and the other end of the cable is provided with a flaw detector head. A mounting groove is provided on the right side of the front surface of the flaw detector body. The drive motor is installed inside the mounting groove. The output end of the drive motor is provided with a transmission shaft. The front surface of the transmission shaft is connected to the drive gear, and the front surface of the drive gear is provided with the main brush head.

[0007] Preferably, the installation slot can be used to install the drive motor, reducing the overall footprint. When the drive motor is working, its output end will drive the drive gear to rotate. When the drive gear rotates, it can drive the main brush head to rotate synchronously, thereby assisting the operator in evenly applying the coupling agent squeezed onto the surface of the steel component during flaw detection. This solves the problem that the existing steel component flaw detection device does not have a structure for evenly applying the coupling agent. When the coupling agent needs to be used, a separate brush is required to spread it evenly, which is inconvenient and time-consuming.

[0008] Preferably, a driven gear is rotatably connected to the right side of the front surface of the flaw detector body, and an auxiliary brush head is provided on the front surface of the driven gear.

[0009] Preferably, both the driving gear and the driven gear are fitted with belts on their outer surfaces, and the belts mesh with the driving gear and the driven gear.

[0010] Preferably, a screw groove is provided in the middle of the front surface of the flaw detector body. A bidirectional screw is rotatably connected to the upper and lower sides of the inner surface of the screw groove. Two mutually symmetrical movable seats are threaded through the outer surface of the bidirectional screw. A clamping assembly is provided on the front surface of the movable seats. A knob is provided on the top rotating shaft of the bidirectional screw through the upper surface of the flaw detector body.

[0011] Preferably, the clamping assembly includes a clamping plate, a positioning groove, and an auxiliary shaft; the front surface of the movable seat is provided with a clamping plate, and the side surface of the clamping plate near the belt is provided with a positioning groove, and the inner surface of the positioning groove is rotatably connected to the front and rear sides with auxiliary shafts.

[0012] Preferably, a slot is provided at the edge of the front surface of the flaw detector body, a protective cover is provided on the front surface of the flaw detector body, and a plug is provided on the rear surface of the protective cover at the position corresponding to the slot, and the slot and the plug are matched.

[0013] Preferably, fixing plates are provided on the front positions of both sides of the flaw detector body, one end of a rubber band is installed on the front position of the side surface of the fixing plate, and the other end of the rubber band is provided with a buckle. The left and right sides of the protective cover are provided with slots that match the buckles.

[0014] The beneficial effects of this utility model are:

[0015] 1. The installation slot allows for the installation of the drive motor, reducing the overall footprint. When the drive motor is in operation, its output will drive the drive gear to rotate. The drive gear will then drive the main brush head to rotate synchronously, thus assisting the operator in evenly applying the couplant extruded onto the steel component surface during flaw detection. This solves the problem that existing steel component flaw detection devices do not have a structure for evenly applying couplant, requiring a separate brush for application, which is inconvenient and time-consuming.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a steel component flaw detection device, including a flaw detector body 1; it also includes a mounting groove 4, a drive motor 5, a transmission shaft 6, a drive gear 7, and a main brush head 8. One end of a cable 2 is disposed on the right side surface of the flaw detector body 1, and the other end of the cable 2 is disposed on a flaw detector head 3. A mounting groove 4 is formed on the right side of the front surface of the flaw detector body 1. The drive motor 5 is disposed inside the mounting groove 4. The output end of the drive motor 5 is disposed on the transmission shaft 6. The front surface of the transmission shaft 6 is connected to the drive gear 7, and the front surface of the drive gear 7 is disposed on the main brush head. The head 8, through the installation slot 4, can be used to install the drive motor 5, reducing the overall footprint. When the drive motor 5 is working, its output end will drive the drive gear 7 to rotate. When the drive gear 7 rotates, it can drive the main brush head 8 to rotate synchronously, thereby assisting the staff to evenly apply the coupling agent squeezed onto the surface of the steel component during flaw detection. This solves the problem that the existing steel component flaw detection device does not have a structure for evenly applying the coupling agent. When the coupling agent needs to be used, a separate brush needs to be found to spread it evenly, which is inconvenient and time-consuming.

[0024] Please see Figures 1-5 In this embodiment, a driven gear 9 is rotatably connected to the right side of the front surface of the flaw detector body 1. An auxiliary brush head 10 is provided on the front surface of the driven gear 9. By providing the driven gear 9, the auxiliary brush head 10 can be rotated when it rotates, thereby cooperating with the main brush head 8 to improve the coating efficiency. A belt 11 is fitted on the outer surface of both the driving gear 7 and the driven gear 9. The belt 11 meshes with the driving gear 7 and the driven gear 9. By providing the belt 11, the driving gear 7 and the driven gear 9 can be linked together. Thus, when the driving gear 7 rotates, the driven gear 9 can be rotated through the belt 11. A screw groove 12 is provided in the middle of the surface. A bidirectional screw 13 is rotatably connected to the upper and lower sides of the inner surface of the screw groove 12. Two mutually symmetrical movable seats 14 are threaded through the outer surface of the bidirectional screw 13. A clamping assembly is provided on the front surface of the movable seats 14. A knob 16 is provided on the upper surface of the flaw detector body 1 through the top shaft of the bidirectional screw 13. By providing the knob 16, the bidirectional screw 13 can be rotated when the knob 16 is rotated. When the bidirectional screw 13 rotates, it can drive the two movable seats 14 that are threaded with it to move synchronously, thereby driving the clamping assembly to fit against the outer surface of the belt 11 and preventing the belt 11 from becoming loose.

[0025] Please see Figures 1-5In this embodiment, the clamping assembly includes a clamping plate 151, a positioning groove 152, and an auxiliary shaft 153. The front surface of the movable seat 14 is provided with the clamping plate 151. A positioning groove 152 is formed on the side of the clamping plate 151 closest to the belt 11. The auxiliary shaft 153 is rotatably connected to the front and rear sides of the inner surface of the positioning groove 152. By providing the auxiliary shaft 153, when the auxiliary shaft 153 contacts the belt 11, the friction between them will cause the auxiliary shaft 153 to rotate, thereby limiting the movement of the belt 11 without hindering its normal movement. A slot 17 is formed at the edge of the front surface of the flaw detector body 1. A protective cover 18 is provided on the front surface of the flaw detector body 1, and the rear surface of the protective cover 18 corresponds to the slot 17. Each position is provided with a plug 19, and the slot 17 matches the plug 19. By setting the protective cover 18, the protective cover 18 can be installed through the plug 19 and the slot 17 when no coupling agent needs to be applied. The left and right sides of the flaw detector body 1 are provided with fixing pieces 20 at the front position. One end of the rubber strip 21 is installed at the front position of the side surface of the fixing piece 20, and the other end of the rubber strip 21 is provided with a buckle 22. The left and right sides of the protective cover 18 are provided with slots 23, and the slots 23 match the buckles 22. By setting the buckles 22 and the slots 23, when the protective cover 18 is closed, the buckles 22 can be inserted into the slots 23, thereby fixing the protective cover 18 and preventing the protective cover 18 from loosening.

[0026] During operation, the driven gear 9, when rotated, drives the auxiliary brush head 10 to rotate, thus cooperating with the main brush head 8 to improve coating efficiency. A belt 11 links the driving gear 7 and the driven gear 9, so that when the driving gear 7 rotates, the belt 11 drives the driven gear 9 to rotate. A knob 16, when rotated, drives the bidirectional screw 13 to rotate. The bidirectional screw 13, when rotated, drives the two threaded moving seats 14 to move synchronously, thereby moving the clamping assembly and the outer surface of the belt 11. To ensure a snug fit and prevent the belt 11 from becoming loose, an auxiliary shaft 153 is provided. When the auxiliary shaft 153 contacts the belt 11, the friction between the two will cause the auxiliary shaft 153 to rotate, thus limiting the movement of the belt 11 without hindering its normal movement. A protective cover 18 is provided, which can be installed through the insert block 19 and the slot 17 without the need for coupling agent. A buckle 22 and a slot 23 are provided, which can be inserted into the slot 23 when the protective cover 18 is on, thereby fixing the protective cover 18 and preventing it from becoming loose.

[0027] Through the above steps, the installation slot 4 can be used to install the drive motor 5, reducing the overall footprint. When the drive motor 5 is working, its output end will drive the drive gear 7 to rotate. When the drive gear 7 rotates, it can drive the main brush head 8 to rotate synchronously, thereby assisting the staff to evenly apply the coupling agent squeezed onto the surface of the steel component during flaw detection. This solves the problem that the existing steel component flaw detection device does not have a structure for evenly applying the coupling agent. When the coupling agent needs to be used, a separate brush needs to be found to spread it evenly, which is inconvenient and time-consuming.
