Problems solved by technology

But in practical application, because the distance between the contact wire and the rail surface is relatively low, when the platform rises to a certain height, the platform guardrail withstands the catenary wire and prevents it from rising. It is very unsafe to hang people on the contact net for maintenance, and the maintenance effect is not good.
The catenary components installed at the tunne

Embodiment Construction

[0024] figure 1 , figure 2 Among them, the main platform 1 is connected with the main column 2, and the left horizontal cantilever 7 and the right horizontal cantilever 8 are hinged on the main column 2 and the main platform 1. The left column 5 and the right column 6 link to each other with the left horizontal cantilever 7 and the right horizontal cantilever 8 respectively, and the left platform 3 and the right platform 4 link to each other with the left column 5 and the right column 6 respectively. The left side platform 3 and the right side platform 4 can turn around the left column 5 and the right column 6 respectively. Escalator 10 links to each other with main platform 1. The left horizontal cantilever 7 can rotate to the left around the hinge point of the main column 2, thereby rotating the left platform 3 to the far left. The right horizontal cantilever 8 can rotate to the right around the hinge point of the main column 2, thereby rotating the right platform 4 to t...

Abstract

The invention relates to a contact net inspection device. A main platform is arranged on the upper part of a main column. The rear ends of horizontal suspension arms are installed on the main column, and side columns are arranged at the front ends of the horizontal suspension arms. The side platforms are installed on the side columns. The main column consists of M retractable structures. A main oil cylinder for driving the main platform to lift is arranged on the lower part of the main platform. The side column consists of N retractable structures. Side oil cylinders for driving the side platforms to lift are arranged on the lower parts of the side platforms capable of rotating around the centers of the side columns. The main platform is provided with a suspension arm oil cylinder or a hydraulic motor for driving the horizontal suspension arms to drive the side platforms to rotate around a hinged point of the main column. The device provided by the invention is installed on a contact net operation trolley and can replace original rotary lifting operation platform for maintaining and preserving the contact net for electrified railways. The main platform is lifted to maintain the contact leads and parts on the lower part of the contact net. The side platforms can avoid the contact net lead and are lifted to the highest position. The device provided by the invention is convenient in operation, agile in function and compact in structure.

Description

technical field [0001] The invention relates to a catenary maintenance device. Background technique [0002] The catenary is a set of special transmission lines erected along the electrified railway to supply power to locomotives and motor cars. The contact wires in contact with the locomotive pantograph are at least 5700mm from the rail surface and the highest is 6500mm. The lowest is about 7000mm, and the highest is about 9000mm. [0003] The catenary maintenance vehicle is an important equipment vehicle for maintenance of the catenary. The current catenary maintenance operation vehicle is equipped with a rotary lifting operation platform. The platform is a single platform, which can be raised and lowered, and can also be rotated by plus or minus 120o. When the platform is raised to the highest level, the distance between the floor surface and the rail surface can reach 7200mm. But in practical application, because the distance between the contact wire and the rail surfa...
