Description

Rigid moveable contact line

Technical field

The utility model relates to a kind of movably railway electrification contact system, particularly is arranged at places such as railway container harbour, loading ramp, maintenance garage, public iron level crossing, at a time between in can realize that its rigid contact net that moves moves.Comprise one section rigid-flexibility transition section in the utility model.

Background technology

Above the electrified railway circuit, must be provided with the contact system that electric power is provided to locomotive.And railway container harbour, loading ramp, maintenance garage etc. that contact net for power supplying is set are located, because the charged contact system of aspect on the compartment, make loading and unloading operation etc. that certain difficulty all be arranged, nor safety.A solution of present stage is after the container train by electric locomotive traction enters Freight Stations, changes by internal combustion again and transfers locomotive to carry out shunting service, train is stopped the laggard luggage of loading and unloading track that is not provided with the power supply gauze thereon unload operation.But this mode of operation exists following shortcoming: a. from container train running flow process, electric locomotive sails into when loading and unloading track (electrochemical linked network) is prepared to dispatch a car outside the street loading zone, the inevitable existence because the train that internal combustion accent machine pushes is not in place or because of inertia is strayed into the problem in loading and unloading track in the street loading zone (non-electrification district), electric locomotive can not be travelled by electricity.B. the not electrochemical linked network of loading and unloading track in the street loading zone, the container train of electric locomotive traction can not directly enter loading and unloading track in the street loading zone, can only adopt internal combustion accent machine to carry out shunting service, and not only efficient is low, and influence receiving track and normally drive a vehicle, have influence on the quick, smooth and easy of Railway Container Transport.

Summary of the invention

The utility model provides a kind of movably contact system, this contact system can move to beyond the job position when carrying out cargo handling operation, to avoid the influence of contact system to operations such as loading and unloading, and after operations such as loading and unloading are finished, contact system can return to its control position, and power supply power locomotive is subjected to.

The utility model is a kind of rigid moveable contact line, it by: be fixed with revoliving arm with hinge on it, two power pillars, that be fixed with revoliving arm with hinge on it and be located at passive pillar between two power pillars, be fixed in the insulator of the front end of revoliving arm,, in rigid suspended, be provided with expansion joints in the fixing movable rigid suspended formation of insulator front end, the above revoliving arm of two power pillars is with motor, actuator drives, and is equiped with limit switch on its driving device.

The limit switch of driving device is near switch in the utility model.

Movable rigid suspended end of the present utility model and can be provided with the plug that electrically contacts of a protrusion with the rigid section touching position position of rigid-flexibility transition section, be provided with in rigid-flexibility transition section and touching position position, moveable contact line end one can with the female socket that plug matches that electrically contacts of aforesaid protrusion.The electrically contacting plug and be located at female socket on the rigid-flexibility transition section of protrusion of movable rigid suspended end is located in utilization, can realize movable rigid suspendedly connecing electricity at control position, and the function that when off-position, can cut off the power supply.

The utlity model has following advantage:

1, the utility model provides this rigid moveable contact line may command contact system to remove from track top and reset.Therefore after railway container harbour, loading ramp, maintenance garage, public iron level crossing etc. locate to be provided with this device, when having train to enter street loading zone, the contact system that is fixed on the revoliving arm is in control position, promptly be positioned at the top of track central authorities, can make electric locomotive be subjected to the electrical haulage train to enter street loading zone; When loading and unloading operation, drive motor work, driving driving device makes revoliving arm produce the rotation on plane, the rigid suspended main track that shifts out on the revoliving arm is fixed in drive, has enlarged the loading and unloading operation space, does not influence loading and unloading operation, simultaneously, owing between rigid suspended and just outstanding transition phase, be provided with the power connection equipment of forming by concavo-convex slot and plug, can make the rigid suspended outage of removing main track, further guaranteed the safety of loading and unloading operation.Reached not only realize in the street loading zone electrified but also do not influence the purpose of loading and unloading operation.

2, the utility model integral structure is simple relatively, and manufacturing cost is lower.

3, Zhuan Zhi reliability is higher.
