Description

Technical Field

[0001] This utility model relates to the field of CRH3 series EMU vehicle maintenance technology, and in particular to a combination tool for treating the adhesive surface of the end junction box cover. Background Technology

[0002] During advanced maintenance of CRH3 series EMUs, in accordance with the vehicle maintenance procedures, it is necessary to perform inspections on the electrical connection-related components (jump wires, terminals, terminal blocks, electrical connectors, etc.) at the ends of each model of the train, including visual cleaning, component inspection, and electrical connection status checks. To ensure the stability of electrical functions, operators need to visually inspect the inside of the enclosure for moisture or water ingress. For end junction boxes that have become damp or have water ingress, fault data analysis and recording should be performed. In particular, electrical components and cables that have developed rust or verdigris should be replaced promptly. Through long-term collection and analysis of vehicle operation fault data, it was found that electrical grounding faults were mainly concentrated in the end junction box area. Most fault data indicated that this was primarily caused by water ingress or dampness inside the box. By analyzing fault gaps and conducting on-site simulations, the underlying causes of the faults were identified. The key to solving the problem lay in the handling of residual sealant and reapplication of sealant during the disassembly and installation of the end junction box inspection port cover. The original tools (flathead screwdriver, utility knife) were insufficient to completely remove residual sealant due to space limitations, resulting in hidden quality issues such as air bubbles and breaks on the sealant surface. Furthermore, during the reapplication process, repeatedly smoothing the sealant surface and removing excess sealant with only fingers increased the operator's workload and posed a risk of injury from sealant chemicals.

[0003] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a combination tool for treating the adhesive surface of the end junction box cover. Utility Model Content
