Railway catenary comprehensive operation vehicle body

Abstract

Provided is a railway contact network comprehensive operation vehicle. The railway contact network comprehensive operation vehicle comprises a vehicle body and an underframe. The vehicle body is fixed at the upper end of the underframe and is of a square cylindrical structure, cabs are arranged at the front end and the rear end of the vehicle body, the front end of each cab is of a streamline type structure, the underframe is of a double middle beam box type structure, and partition walls are arranged in the vehicle body to divide the vehicle body into a plurality of intervals, and a plurality of intervals are communicated with each other. An operating device installing seat, a detection device installing seat, a movable skylight for workers to go in and out and an anti-skidding walkway are arranged at the top of the vehicle body, and interior decorations are installed on an inner wall surface of the vehicle body simultaneously. A vehicle side wall is directly welded to an underframe edge beam, a ceiling steel structure is welded to a side wall through an upper chord beam, an overall framework half load-bearing type vehicle structure is formed and has enough strength and stiffness, the self weight of the vehicle is reduced, the front-end and rear-end streamlines of the vehicle meet the requirements of the quasi-high speed pneumatic appearance, a steel plate is formed by splicing welding, and the railway contact network comprehensive operation vehicle is simple in structure and is easily formed by processing.

Description

technical field [0001] The invention belongs to the technical field of railway catenary maintenance machinery, and in particular relates to a railway catenary operation vehicle body. Background technique [0002] With the large-scale speed increase of existing railway lines in my country to 160-200km / h and the opening of new passenger dedicated lines of 200km / h and above, it is difficult for the original operating vehicles to adapt to the needs of railways under the new situation. High-speed, energy-saving and high-reliability The comprehensive operation vehicle will become a new demand for the maintenance department of the railway catenary. Currently, the vehicle body is usually made of solid plates, and its own weight is too large to adapt to high-speed running. Therefore, it is necessary to improve. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a car body of a railway catenary comprehensive operation vehicle,...

[0002] With the large-scale speed increase of existing railway lines in my country to 160-200km / h and the opening of new passenger dedicated lines of 200km / h and above, it is difficult for the original operating vehicles to adapt to the needs of railways under the new situation. High-speed, energy-saving and high-reliability The comprehensive operation vehicle will become a new demand for the maintenance department of the railway catenary. Now the vehicle body is usually made of solid plates, and its own weight is too large to adapt to high-speed running. Therefore, it is necessary to improve
