When the lifting mechanism 120 drives the shift disk 121 and the protective shell 130 to move downward, the pull rope 170 pulls the rack 325 to move along the guide column 2 324, thereby driving the gear 1 321 to rotate, and then drives the gear 2 and the gear ring to rotate, and then drives the support ring 210 to rotate, thereby driving the detection plate 222 to rotate, and the brush 226 on the board surface of the detection plate 222 cleans the impurities on the side circumferential surface of the ceramic carrier.

[0039] Working principle:

[0040] During the use of the present invention, when the lifting mechanism 120 drives the shift plate 121 and the protective housing 130 to move downward, the pull rope 170 pulls the rack 325 to move along the guide column 2 324, thereby driving the gear 1 321 to rotate, and then drives the gear 2 and the gear ring to rotate, and then drives the support ring 210 to rotate, thereby driving the detection plate 222 to rotate, and the brush 226 on the surface of the detection plate 222 cleans the impurities on the side circumferential surface of the ceramic carrier, and the rack 325 moves along the guide column 2 324. During the movement, the supporting rod 326 is driven to move, and then the guide rod 327 contacts the bottom edge of the lifting plate 333, thereby driving the lifting plate 333 to move upward, thereby driving the limiting plate 334 to move upward, and the limiting column 335 passes through the opening at the top of the carrier 110 and extends into the through hole of the ceramic carrier, thereby limiting the ceramic carrier to prevent the ceramic carrier from shifting. After the lifting mechanism 120 drives the shift plate 121 and the protective shell 130 to move downward, the bottom edge of the protective shell 130 contacts The top surface of the guide plate 224 drives the detection plate 222 to move away from the ceramic carrier, and then the telescopic cover 131 covers the ceramic carrier, and the cylinder 140 pushes the push plate 141 to move, thereby pushing the hydraulic oil in the liquid storage cylinder 150 into the protective shell 130 for pressurization, thereby pressurizing the telescopic cover 131, and thus pressurizing the side circumferential surface of the ceramic carrier. The pressure sensor 151 performs hydraulic detection on the liquid storage cylinder 150. When the predetermined pressure is reached, the side circumferential surface of the ceramic carrier is pressurized for a period of time, and then the pressure on the ceramic carrier is withdrawn through the cylinder 140. The lifting mechanism 120 drives the shift plate 121 and the protective shell 130 to move upward, and the elastic force of the spring 2 pushes the rack 325 to reset. In the process of pushing the rack 325 to reset, the elastic force of the spring 2 drives the detection plate 222 to rotate, and the ultrasonic probe on the surface of the detection plate 222 performs crack detection on the side circumferential surface of the ceramic carrier, thereby performing isostatic pressure test on the side circumferential surface of the ceramic carrier.

[0041] It should be noted that the above specific implementations are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can be made to the present invention. However, as long as these changes do not deviate from the spirit of the present invention, they should be within the scope of protection of the present invention. In addition, some terms used in the specification and claims of this application are not restrictive, but are only for the convenience of description.

3. A test method for an isostatic pressure test device for a honeycomb ceramic coated carrier side circumferential surface, applied to an isostatic pressure test device for a honeycomb ceramic coated carrier side circumferential surface according to any one of claims 1-2, characterized in that: The steps include: S1. When the lifting mechanism drives the shift plate and the protective shell to move downward, the pull rope pulls the rack to move along the guide column 2, thereby driving the gear 1 to rotate, and then drives the gear 2 and the gear ring to rotate, and then drives the support ring to rotate, thereby driving the detection plate to rotate, and the brush on the detection plate surface cleans the impurities on the side circumferential surface of the ceramic carrier. When the rack moves along the guide column 2, it drives the supporting rod to move, and then the guide rod contacts the bottom edge of the lifting plate, thereby driving the lifting plate to move up, thereby driving the limit plate to move up, and the limit column extends through the opening at the top of the bearing platform into the through hole of the ceramic carrier, thereby limiting the ceramic carrier; S2. After the lifting mechanism drives the shift plate and the protective shell to move downward, the bottom edge of the protective shell contacts the top surface of the guide plate 1, thereby driving the detection plate to move away from the ceramic carrier, and then the telescopic cover is covered on the ceramic carrier, and the cylinder pushes the push plate to move, thereby pushing the hydraulic oil in the liquid storage cylinder into the protective shell for pressurization, thereby pressurizing the telescopic cover, and thus pressurizing the side circumferential surface of the ceramic carrier. The pressure sensor performs hydraulic detection on the liquid storage cylinder. When the predetermined pressure is reached, the side circumferential surface of the ceramic carrier is pressurized for a period of time, and then the pressure on the ceramic carrier is removed by the cylinder, and the lifting mechanism drives the shift plate and the protective shell to move upward, and the elastic force of the spring 2 pushes the rack to reset. In the process of pushing the rack to reset, the elastic force of the spring 2 drives the detection plate to rotate, and the ultrasonic probe on the surface of the detection plate performs crack detection on the side circumferential surface of the ceramic carrier.
