Full-area railway overhead line system maintenance operation device

Abstract

The full-area railway overhead line system maintenance operation device comprises a main platform and two rotary platforms, the lower portion of the main platform is fixed to a vehicle body ceiling through a main platform mounting base, the two rotary platforms are arranged at the two ends of the main platform respectively, and the lower portions of the rotary platforms are fixed to a vehicle body underframe through rotary platform lifting columns; an auxiliary platform is arranged on the upper portion of the main platform and forms a main operation unit together with the main platform, and an auxiliary platform is arranged on the upper portion of each rotary platform and forms a rotary operation unit together with the rotary platform. According to the overhead line system operation device, all-area overhaul and maintenance of overhead line system wires, droppers, carrier cables, supporting devices, positioning devices and additional suspensions can be met, simultaneous operation of the carrier cables and contact lines of four suspension points of an overhead line system can be achieved, the operation efficiency is at least improved by four times or above compared with an existing operation device, the operation area is at least improved by 4.5 times or above compared with the existing operation device, and the operation cost is reduced. And the operation range has no blind area.

Description

technical field [0001] The invention belongs to the technical field of railway engineering machinery, and in particular relates to an all-area railway catenary maintenance operation device suitable for electrified railway catenary operation. Background technique [0002] At present, the maintenance operation devices of railway catenary mainly include lifting and rotating operation platform, three-operation platform, aerial work bucket and so on. The lifting and rotating operation platform is a traditional catenary operation device. Its structure, electrical and hydraulic controls are relatively backward, and due to structural limitations, it is impossible to overhaul the catenary catenary cable, the upper part of the column, the support and positioning device, etc.; three operating platforms There are three working platforms that can work at multiple points and on multiple sides at the same time, but the space and load of each working platform are small; the aerial work buck...

AI Technical Summary

Problems solved by technology

The lifting and rotating operation platform is a traditional catenary operation device. Its structure, electrical and hydraulic controls are relatively backward, and due to structural limitations, it is impossible to overhaul the catenary catenary cable, upper facilities of the column, support and positioning devices, etc.; three operating platforms With three working platforms, it is possible to work at multiple points and sides at the same time, but the space and load of each working platform are small; the aerial work bucket is flexible in operation, but there are also problems of small space and small load of a separate working bucket

To sum up, the existing operating devices have the problems of small operating space and load, low operating efficiency, and blind spots in the operating range.
