Description

Overturn protection device for catenary maintenance work vehicle

technical field

The invention belongs to the technical field of maintenance equipment, and in particular relates to a rollover protection device for a catenary maintenance vehicle.

Background technique

The top-mounting car body and protective railings are important components of the JJC catenary maintenance work vehicle, and are also the main protective structure to protect the maintenance operators. With the rapid development of my country's electrified railways, higher requirements are put forward for the protective structure of catenary equipment maintenance. At present, the original JJC catenary operating vehicle climbing ladder adopts a vertical ladder, and the upper and lower personnel need to climb to the working platform when the platform is raised, which has problems such as less protection area, inconvenient climbing when personnel carry tools for operation, and potential safety hazards. , it is difficult to meet the requirements of the current high-speed railway development.

The patent application number is 201510457902.2, and the file name is "An automatic overturning guardrail for a working platform". The automatic overturning guardrail set on the working platform is disclosed, which solves the problem that the railing on the working platform is too high and leads to super high, and at the same time, it imposes restrictions on the operators.
