Rigid movable overhead line system below electrified railway coal hopper bunker

Abstract

The invention relates to a rigid movable overhead line system below an electrified railway coal hopper bunker. The existing movable contact line system generally driven by gear and rack or sprockets jams easily by accumulated dust, operation of locomotive pantographs has security problem, independent operation steps are required, and potential hazards caused by manual misoperation exist. The rigid movable overhead line system comprises two portal frames on two sides of a hopper bunker and a rigid movable contact line system body between the portal frames. A travelling trolley is mounted on a beam of each portal frame. The bottom of every travelling trolley is connected with the rigid movable contact line system body. The travelling trolleys are connected with a charge chute below the hopper bunker through pulleys and traction ropes. Two ends of the rigid movable contact line system body are smoothly connected with a fixed contact line system. The rigid movable overhead line system allows a locomotive to pass the coal hopper bunker without lowering the pantograph or being electrified, the requirement of the locomotive for straight-through transport is met, the structural strength of the rigid movable contact line system body is higher, contact lines can be fully covered, and operation troubles of the locomotive pantograph are less.

Description

technical field [0001] The invention relates to a catenary, in particular to a rigid movable catenary under an electrified railway coal charging funnel bin. Background technique [0002] The continuous coal charging equipment of the funnel bin has been popularized and applied due to its technical characteristics of high precision, high speed, quantitative coal charging and environmental protection. Since the hopper warehouse is erected above the railway, there must be no catenary live equipment near the opening of the coal loading chute during the coal loading operation. A movable catenary is set under the hopper bin, and the catenary is partially removed during the coal loading operation, and the catenary is moved to the top of the railway when the train enters and exits the coal loading area to supply power for the electric locomotive. Most of the existing movable catenary structures have the following technical problems: 1. The insulated contact guide rod cannot supply ...

AI Technical Summary

Problems solved by technology

Most of the existing movable catenary structures have the following technical problems: 1. The insulated contact guide rod cannot supply power to the electric locomotive, and when the electric locomotive stops by mistake in the non-electric area under the funnel storehouse, it can only wait for the rescue of the diesel locomotive; 2. Adopt rack and pinion transmission or sprocket transmission, there is a problem of coal dust sticking; 3. A single contact wire is used to pass through the funnel bin, and the exposed contact wire is easy to fall coal and accumulate dirt during the coal loading operation in the funnel bin. The operation safety of the electric locomotive pantograph; 4. The driving motors on the two sets of gantry frames lack synchronization technology, and there are fatigue and life problems of a single contact wire; 5. The mobile catenary requires independent operation steps, and there are human errors Hidden dangers, and affect the efficiency of coal loading operations
