Description

Technical Field

[0001] The utility model relates to the technical field of cooler tube bundle processing, in particular to a repair tool for a cooler tube bundle. Background Art

[0002] A common tool used for cooler tube bundle repair is a tube bundle extractor or tube bundle extraction tool. This tool is used to safely and efficiently remove and install cooler tube bundles for repair and replacement of damaged or aged tube bundles.

[0003] After searching, Chinese patent announcement number: CN217240517U discloses an electric spindle maintenance tool, including a mobile work trolley, an electric spindle stator part and an electric spindle rotor part. The top of the mobile work trolley is provided with a connection mechanism to prevent the disassembly from being unable to be removed due to the strong internal magnetic field during disassembly and maintenance. The electric spindle maintenance tool is configured to insert the electric spindle into the retaining frame, fix the electric spindle rotor part with the sliding bracket connecting nut, then loosen the front and rear bearing end cover fixing bolts, move the sliding plate, and the slide block moves laterally along the slide rail, which can overcome the strong magnetic field, slowly separate, and gradually pull out the electric spindle rotor part and the front end cover part, and then place the rotor and the bearing assembly on the rotor maintenance placement seat to replace and assemble the new bearings, thereby solving the problem that the strong magnetic field inside the electric spindle causes the strong suction force to make it impossible to effectively separate and install the electric spindle. However, when the above-mentioned device is used to repair the electric spindle, the electric spindle needs to be flushed. Traditionally, it is done manually on the ground. Due to the large impact force of the water gun, it is easy to swing during operation, which is very inconvenient and consumes physical strength, making it inconvenient to flush the tube bundle well. Therefore, a maintenance tool for the cooler tube bundle is proposed to solve the above-mentioned problem. Utility Model Content
