Abstract
The utility model relates to a short circuit device in rail circuit, in particular to a short circuit device in rail circuit of gear-engaged locomotive between wheel pairs. The technical problem to be solved by the utility model includes low shunting sensitivity due to large contact resistance between wheels of the locomotive, resulting from the gap among gears and the lubricating oil filled in the gap. The short circuit device of rail circuit of gear-engaged locomotive between wheel pairs comprises a support and a copper alloy carbon brush fixed on the support, wherein the support is fixed on the main body of the locomotive, and the copper alloy carbon brush is adjacent to a brake pad. The utility model is mainly used for improving signal shunting sensitivity during single unit operation of the locomotive.
Description
Technical field:
The utility model relates to a kind of track circuit short circuit device, and particularly a kind of wheel can improve the shunting sign sensitivity of locomotive when light locomotive running to being the track circuit short circuit device of gear mesh locomotive.
Background technology:
U.S.'s Teramo generally is used for interval interior shipping work than the TM4650 type locomotive that company produces, and this locomotive when interval light locomotive running not detected artifacts of track circuit often takes place, and causes interval shunting sign bad, and production brings adverse effect to transportation safety.According to the track circuit action principle, when having locomotive operation, interval circuit takes turns making two rails form short circuit by it, track circuit shows that this interval has locomotive to take, and the TM locomotive wheel is to a conducting by gear mesh, when locomotive turns round, there is the gap and is full of lubricating oil owing between gear, make locomotive wheel big, thereby cause shunting sensitivity to reduce a contact electricity resistance.The initial short circuit device that is made of pinch device and antifriction-bearing box that installed additional between body and brake disc is used for reducing locomotive wheel to a contact electricity resistance, but have only the service life that is in operation about 15 days, and because the Internal and external cycle of antifriction-bearing box is by a contact that is connected to of steel ball, effect is undesirable.This just requires and must redesign short circuit device, improves service life and utilization effect.
Summary of the invention: the purpose of this utility model provides a kind of wheel to being the track circuit short circuit device of gear mesh locomotive, in order to improve the shunting sign sensitivity of locomotive when the light locomotive running.The utility model technical issues that need to address are: have the gap between gear and be full of lubricating oil, make locomotive wheel big to a contact electricity resistance, thereby cause shunting sensitivity to reduce.
The technical solution of the utility model is: wheel comprises support and is fixed on copper alloy carbon brush on the support that support is fixed on the car body to being the track circuit short circuit device of gear mesh locomotive, the copper alloy carbon brush is abutted against brake facing.
The beneficial effects of the utility model are: by gear drives such as additional track short circuit device tripping difies, because brake disc and wheel hub one, thereby make left and right sides rail wheel conducting.And contacting between copper alloy carbon brush and brake disc be the face contact, greatly reduces contact resistance, improved the shunting sign sensitivity of locomotive when light locomotive running.
Description of drawings:
Accompanying drawing is the utility model mounting structure scheme drawing
Among the figure: 1-rim, 2-brake facing, 3-support, 4-diff, 5-wheel shaft, 6-copper alloy carbon brush.
The specific embodiment: with reference to accompanying drawing, wheel comprises support 3 and is fixed on copper alloy carbon brush 6 on the support that support is fixed on the car body to being the track circuit short circuit device of gear mesh locomotive, and copper alloy carbon brush 6 is abutted against brake facing 2.
Described support 3 can be fixed on the brake clamp between car body wheel hub and the brake facing, on support, install by copper alloy carbon brush 6, adjust the distance of 2 of support 3 and brake facings, make copper alloy carbon brush 6 and locomotive brake sheet 2 keep suitable thrust, like this by additional track short circuit device tripping diff 4 gear drives such as grade, because brake facing and wheel hub 1 one, thereby make left and right sides rail wheel conducting.In the test of different circuits, area operation (unit speed at 0-20KM/H time), record between two rails residual voltage through unit in the 0.08-0.45V scope, (the technical requirements of residual voltage≤2.7V) along separate routes when meeting track circuit and taking.This track circuit short circuit device has obtained bigger raising service life simultaneously, can reach the time more than 18 months, and maintenance is convenient, gets final product place in operation to only needing to change the copper alloy carbon brush in limited time.
