Intelligent lifting insulated arm pantograph

Abstract

The invention belongs to the technical field of mechanical devices and rail transit transmission, and particularly relates to an intelligent lifting insulated arm pantograph. The intelligent lifting insulated arm pantograph comprises a lifting base, a lower insulated arm, an upper insulated arm, a pantograph head with an insulated pantograph horn, a pantograph lifting cylinder, an intelligent control cabinet, an angle sensor and a height sensor. The intelligent lifting insulated arm pantograph adopts the design of the upper and lower arms and the insulated pantograph horn, so that an insulatorbetween the pantograph and a vehicle body is omitted, and equivalently the minimum working height of the pantograph is increased; when the lifting base is in a lifted state, equivalently the maximumworking height of the pantograph is decreased; the minimum working height and the maximum working height of the pantograph during working are optimized, and the pantograph is always kept at the more comfortable working height, so that the current collecting stability of the pantograph is guaranteed and the service life of a pantograph sliding plate is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of mechanical devices and rail transit power transmission, and in particular relates to an intelligent lifting type insulating arm pantograph. Background technique [0002] The catenary is the main frame of the railway electrification project, and it is a special form of transmission line erected along the railway line to supply power to the electric locomotive. The catenary wire height (referred to as the guide height) refers to the vertical height of the contact line at the suspension positioning point from the rail surface. Under different situations and positions, the guide height varies greatly. For example, the middle position of a catenary section is much lower than the nodes due to gravity, and the conduction height in the tunnel is further reduced due to construction difficulty and cost considerations. These circumstances force the pantograph to be lower than It works under the allowable working he...

Problems solved by technology

For example, the middle position of a catenary section is much lower than the nodes due to gravity, and the conduction height in the tunnel is further reduced due to construction difficulty and cost considerations. These circumstances force the pantograph to be lower than It works under the allowable working height range. At this time, the pantograph-catenary pressure is high, and the wear and tear of the catenary and the carbon slide of the pantograph increase, which seriously affects the service life of both; Elevate the catenary, forcing the pantograph to work higher than its allowable working height range. At this time, the pantograph-catenary pressure is small, which can easily cause the pantograph to break off the grid and arc. The arc also seriously affects the catenary and pantograph. Carbon Skateboard Lifespan

A small pantograph with a short bow arm should be used for low conductance heights, and a large pantograph with long bow arms should be used for high conductance heights. However, there is currently no pantograph in the world that can adapt to different conductance sections at the same time.
