Overhauling line of water supply and drainage system

Abstract

The invention relates to an overhauling line of a water supply and drainage system. The overhauling line of the water supply and drainage system comprises two overhauling lines, wherein one overhauling line comprises a to-be-overhauled buffer region, a water pumping device overhauling region, an electric drinking water boiler overhauling region and a storage region; the other overhauling line comprises a washing and drying region, a sewage box overhauling region, a toilet stool overhauling region and a storage region; the two overhauling lines share one to-be-overhauled buffer area; according to the requirements of an overhauling process of the water supply and drainage system, the convenience of overhauling and the sufficient utilization of space are simultaneously considered, so as to avoid repeatedly transporting devices, reduce repeated work and improve the overhauling efficiency; and the overhauling line is divided into the to-be-overhauled buffer region, a washing region, a working region and a repaired part storage region. Work station number for an overhauling test of the parts of the water supply and drainage system is small and the volumes of the parts are relatively large, so that an electric hoisting trolley is used for finishing the transportation of each part, ascending and descending a worktable and the like; corresponding equipment including the worktable, a test-bed, a control platform, a tool case and the like is arranged on each overhauling and assembling test region, thereby realizing the overhauling work of storing, decomposing, overhauling, assembling, testing and the like of the water supply and drainage system.

Description

technical field [0001] The invention relates to a maintenance device for a water supply and drainage system, in particular to a maintenance device suitable for the components of the water supply and drainage system of a CRH2 type train set, and compatible with the maintenance of components of the water supply and drainage system of other types of train sets. Background technique [0002] At present, the CRH1, CRH2, CRH3 and CRH5 EMUs in operation are the main types of high-speed trains in my country. With the rapid development of the train business, the quality of the corresponding train accessories needs to be improved, especially the improvement of the performance of the train water supply and drainage system. The comfort of passengers is greatly affected. Now most of the maintenance of the water supply and drainage system is not in order, and it is carried out in blocks. Overhaul was developed. Contents of the invention [0003] The purpose of the present invention is to...

[0002] At present, the CRH1, CRH2, CRH3 and CRH5 EMUs in operation are the main types of high-speed trains in my country. With the rapid development of the train business, the quality of the corresponding train accessories needs to be improved, especially the improvement of the performance of the train water supply and drainage system. The comfort of passengers is greatly affected. Now the maintenance of the water supply and drainage system is mostly out of order, and it is carried out in blocks. Not only the maintenance process is troublesome, but also most of them rely on manual labor, and the maintenance accuracy is not high. Therefore, it is especially for the water supply and drainage system. Overhaul was developed
