Description

Split type track switch beam body

Technical field

The utility model belongs to rail traffic switch manufacture technical field, and in particular to a kind of split type track switch beam body.

Background technology

Suspension type unoccupied orbital trouble according to the difference of bogie be divided into face bottom surface out of shape it is continuous, with discontinuous two kinds.

The discontinuous track switch in face out of shape has steady wheel group, guide wheel group on bogie, can be provided by torsional rotation force Square steps on sky in short-term in the unilateral travelling wheel of track switch design permission, and the type track switch is mainly used in Germany.Changing points driving is adopted With a goat of more standard, total power is less than 1kw.Operation principle：Made by the power of goat With the pivoting for pushing intermediate revolution core rail respectively；Turn preceding solution of revolution fork core is realized in the flexible cycle of the trapezoidal Steel Structure in front end Lock, in place locking.The type track switch is only applicable to small freight volume, the empty rail system of axis weight relatively light (3.5 tons).

Track switch operating method

As equipment crucial in circuit, it is necessary to meet the requirement of signal, while meet the maintenance under special state, behaviour It is required, therefore the operation of track switch is had into following three kinds of citation forms：

Remote operation (signal and gearing)-is usually

Track switch runs well in use, completing the manipulation of track switch by long-range signal box, and track switch receives drop-on-demand, leads to The control system of turnout passing itself completes turn-out track, and by the closely connected signal of itself, in place after the comprehensive descision of travel switch, to Long-range signal box beams back signal in place.

When live push-botton operation-maintenance overhaul

Track switch is in maintenance overhaul, by sending out the mandate requirement of execute-in-place to long-range signal box, and by license Afterwards；The maintenance overhaul action of each substep is completed by the control system of track switch itself.

At this time two limit positions should be able to pass through itself closely connected signal, travel switch in place comprehensive descision, to long-range Signal box beam back position signal.

When on-site manual operation-has a power failure and breaks down

Track switch should be able to complete corresponding action when having a power failure and breaking down by the handle of each driving motor tail portion.
