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 rigid moveable contact line under the funnel bin of coalingging.
Background technology
This continuous coaling facilities of funnel bin with its accurately high, speed soon, is quantitatively coaling and technical characterstic such as environmental protection has obtained the application of promoting.Because funnel bin is erected at the railway top, coalingging in the operation process of coalingging can not have the contact system charging equipment near the chute mouth, but, for improving the transportation speed that the coal transporting train turnover is coaling and distinguished, and the operation of coalingging continuously of not stopping, need the funnel bin below that moveable contact line is set, the contact system part is removed when coalingging operation, and contact system is the electric locomotive power supply above moving to railway when coaling in the district in the train turnover.Present existing portable contact system structure, have following technical matters mostly: 1, insulation contact guide rod can not be powered for electric locomotive, when electric locomotive can only be waited for the diesel locomotive rescue during non-electricity zone mistakenly stop under funnel bin; 2, adopt rack-and-gear transmission or chain sprocket drive, have long-pending coal dust clamping stagnation problem; 3, adopt leakage hopper under the single contact wire, the contact wire of exposure is easy coal breakage contamination when funnel bin is coaling operation, has block of bow collector of electric locomotive safe in operation problem; 4, the drive motor on two groups of door type frames lacks simultaneous techniques, has fatigue and the life problems of single contact wire; 5, mobile catenary needs the independent operation step, has human operational error's hidden danger, and influences the operating efficiency of coalingging.
Summary of the invention
It is high and can effectively avoid the electrified railway of the coal breakage contamination rigid moveable contact line under the funnel bin of coalingging to the purpose of this invention is to provide a kind of body construction intensity.
The technical solution adopted in the present invention is:
The electrified railway rigid moveable contact line under the funnel bin of coalingging includes two groups of door type frames and the rigidity mobile catenary body between two groups of door type frames in the funnel bin both sides, it is characterized in that:
A traveling dolly respectively is installed on the crossbeam of described two groups of door type frames, and two traveling dollies bottom connects rigidity mobile catenary bodies, and two traveling dollies are connected with the chute of coalingging under the funnel bin by pulley and hauling rope;
Rigidity mobile catenary body two-end structure and fixedly contact system seamlessly transit.
The bus duct of described rigidity mobile catenary body is suspended on two traveling dolly bottoms by insulator, and the bus duct top connects hoist cable by dropper, and hoist cable is connected to traveling dolly side by spring tensioner.
Be connected with No. two hauling rope on the described traveling dolly, No. two hauling ropes are walked around No. three fixed pulleys that are fixed on door type frame corner and are hung with iron bob stone roller.
Connection channel-section steel end on the described chute of coalingging is connected with hauling rope No. one, No. one hauling rope is walked around No. two fixed pulleys that are fixed on the H type davit, walk around a fixed pulley that is fixed on door type frame corner again, walk around the movable pulley that arranges on the traveling dolly 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 the funnel bin of coalingging, and satisfies the straight-through traffic requirements of electric locomotive.Rigidity mobile catenary body can hide contact wire fully when improving structural strength, reduce electric locomotive receptor site bow operating troubles.The mechanical linkage mode is taked in coalingging of mobile catenary and funnel bin between the chute, do not establish drive motor, can reduce power consumption and contact system repair and maintenance work capacity, avoid nonsynchronous technical barrier between two drive motor of prior art, owing to do not establish the independent operation step, can improve and coaling operating efficiency and avoid the human operational error.
