Description

Technical Field

[0001] This utility model relates to the field of boiler inspection, specifically a power plant boiler inspection tool with a tapping inspection function. Background Technology

[0002] During boiler operation, pressure-bearing components may experience defects such as corrosion, deformation, wear, scaling, overheating, and leakage under the action of high-temperature and high-pressure water and steam media, as well as under the radiation of external high-temperature flames or the scouring of flue gas. Regular boiler inspection is an important technical means to ensure the safe operation of boilers. It is divided into internal inspection and external inspection. The most common methods for internal inspection are visual inspection and hammer inspection.

[0003] A search revealed a multifunctional boiler inspection tool disclosed in application number CN202122599361.0. This tool includes a main body comprising an inspection hammer assembly and an inspection hammer handle assembly. The inspection hammer handle assembly is located on the right side of the hammer assembly. The position of the connecting rod can be adjusted via the handle assembly, allowing it to be positioned appropriately. A flaw detector is installed inside the handle; if damage is found after inspection with the hammer assembly, it can be specifically detected using the flaw detector, thus identifying specific boiler problems for timely handling. The hammer assembly allows for striking different parts using the front and rear hammers, and an internal light provides illumination, making the striking location more accurate. The overall device has a simple structure, is easy to operate, and is highly practical. However, the above description has the following drawbacks in actual use: the tool cannot inspect boiler inner walls to a specific depth, and the manual striking function is limited due to structural limitations. Therefore, a more practical power plant boiler inspection tool with a striking inspection function is needed. Utility Model Content

The two ends of the positioning block 23 move along the inner walls of the two through slots 24 and the through groove 13, respectively. This, combined with the positioning pointer 25's adjustment of the scale on the two scales 26, adjusts the position of the mounting base 211 at the other end of the adjusting rod 22. Simultaneously, the positioning block 23 moves the limiting block 27 along the surface of the strip block 1. When the desired position is reached, the two limiting pins 29 are inserted into the corresponding limiting holes 28 and positioning holes 12, thus completing the positioning purpose for the tapping inspection of the inner wall of the power plant boiler. Two micro motors 31 drive two sliders 32 to reciprocate and vibrate on the inner walls of the two grooves 212. The two sliders 32 drive two sets of moving blocks 33 to reciprocate on the guide rods 37 on the inner walls of the two sets of moving grooves 213. The two sets of moving grooves 213 also compress several sets of springs 38 to different degrees, which facilitates the reciprocating striking operation of the first hammer head 34 and the second hammer head 35. This facilitates the striking inspection of the inner wall of the boiler at a deeper location after positioning. The camera 217 and the lighting lamp 215 are used to take pictures and inspect the striking position.
