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
the present invention relates to a kind of contact system, be specifically related to a kind of electrified railway and coaling rigid moveable contact line under funnel bin.
Background technology
This continuous coaling facilities of funnel bin with its accurately high, speed soon, quantitatively to coaling and the technical characterstic such as environmental protection obtains the application of popularization.Because funnel bin is erected at above railway, coaling in coaling operation process near chute mouth and can not have contact net electrification equipment, but, the transportation speed in district of coalingging is passed in and out for improving coal transporting train, and the continuous coaling operation that do not stop, need to arrange moveable contact line below funnel bin, when coaling operation, contact system local is removed, and when being coaling in district in train turnover, contact system moves to above railway as electric locomotive is powered., mostly there is following technical matters: 1, insulated contact guide rod can not be powered for electric locomotive in current existing portable contact system structure, when electric locomotive can only wait for during the mistakenly stop of non-electricity zone that under funnel bin diesel locomotive is rescued; 2, adopt rack pinion or chain sprocket drive, there is long-pending coal dust clamping stagnation problem; 3, adopting leakage hopper under single contact wire, there is block of bow collector of electric locomotive safe in operation problem in contact wire easy coal breakage contamination when funnel bin coaling operation of exposure; 4, the drive motor on two groups of door type frames lacks simultaneous techniques, there is fatigue and the life problems of single contact wire; 5, mobile catenary needs independent operation step, there is the hidden danger of human operational error, and affects coaling operation efficiency.
Summary of the invention
The object of this invention is to provide a kind of body construction intensity high and can effectively avoid the electrified railway of coal breakage contamination to coaling rigid moveable contact line under funnel bin.
The technical solution adopted in the present invention is:
Electrified railway is coaling rigid moveable contact line under funnel bin, includes at two groups of door type frames of funnel bin both sides and the rigid movable contact network body between two groups of door type frames, it is characterized in that:
The crossbeam of two groups of described door type frames is respectively provided with a traveling dolly, connects rigid movable contact network body bottom two traveling dollies, two traveling dollies are connected with the chute of coalingging under funnel bin with hauling rope by pulley;
Rigid movable contact network body two-end structure and fixing contact system seamlessly transit.
The bus duct of described rigid movable contact network body is suspended on bottom two traveling dollies by insulator, connects hoist cable above bus duct by dropper, and hoist cable is connected to traveling dolly side by spring tensioner.
Described traveling dolly is connected with No. two hauling ropes, No. two hauling ropes are walked around No. three fixed pulleys being fixed on door type frame corner and are hung with iron falling mound.
The described connection channel-section steel end of coalingging on chute is connected with a hauling rope, No. two fixed pulleys be fixed on H type davit walked around by a hauling rope, walk around the fixed pulley being fixed on door type frame corner again, walk around the movable pulley that traveling dolly is arranged again, terminal is anchored on the crossbeam of door type frame.
The present invention has the following advantages:
Rigid moveable contact line of the present invention can make electric locomotive not fall pantograph and charged by funnel bin of coalingging, and meets electric locomotive and leads directly to traffic requirements.Rigid movable contact network body can hide contact wire completely while raising structural strength, reduces electric locomotive receptor site bow operating troubles.Mobile catenary and coalingging between chute of funnel bin take mechanical linkage mode, do not establish drive motor, power consumption and contact system repair and maintenance work capacity can be reduced, avoid nonsynchronous technical barrier between two of prior art drive motor, owing to not establishing independent operation step, coaling operation efficiency can be improved and avoid human operational error.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention will be described in detail.
Electrified railway of the present invention is coaling rigid moveable contact line under funnel bin, includes at two groups of door type frames 1 of chute 18 both sides of coalingging and the rigid movable contact network body 3 between two groups of door type frames 1.The crossbeam 5 of two groups of door type frames 1 is all provided with and connects rigid movable contact network body 3, two traveling dollies 11 bottom a traveling dolly 11, two traveling dollies 11 and be connected with chute 18 of coalingging with hauling rope by pulley.Pulley and hauling rope constitute transmission device 15 of the present invention, are the power switching devices of coalingging between chute 18 and rigid movable contact network body 3.Bus duct 7 two ends of rigid movable contact network body 3 are provided with the bus duct terminal 9 for seamlessly transitting with fixing contact system 4.
Rigid movable contact network body 3 is made up of hoist cable 6, bus duct 7, contact wire 8, dropper 10 and insulator 12.The bus duct 7 of rigid movable contact network body 3 is suspended on bottom two traveling dollies 11 by insulator 12, and by the hoist cable 6 that dropper 10 connects above bus duct 7, hoist cable 6 is connected to traveling dolly 11 side by spring tensioner 13.Rigid movable contact network body 3 adopts the rigid suspended of band hoist cable 6, rigid suspended employing " Π " type bus duct 7 clamped contact wire 8, and self does not establish tension compensating, and hoist cable 6 is used for ensureing rigid suspended flatness.
