Description
Technical field
The utility model is applicable to railway switch machine, particularly a kind of conversion locking mechanism with adjustable friction damper.
Background technology
Switch machine is conventionally using motor as propulsion source, for track switch conversion provides power, the function that realizes locking track switch and the location status of track switch is represented.The drive disk assembly of switch machine and rotor still have certain inertia can continue motion after cutting off the electricity supply, after there is Transmission bounce-back in using at the scene, cut off the fault that represents even release, especially the good equipment of break-in state, its inner driving efficiency is compared with high and damping is less, more easily bounce-back.For head it off, some type has been set up damper in transmission device, but the damper of friction-type in use damping can decline, after long-term use, still there will be bounce-back fault.
Summary of the invention
The purpose of this utility model is to be to provide a kind of conversion locking mechanism with adjustable friction damper, and it is easy to use, has solved the problem of switch machine transmission device bounce-back.
The technical solution of the utility model is: which comprises at least locking iron, lock dog, lock dog frame, adjustable friction damper, throw rod, actuating sleeve, it is characterized in that: actuating sleeve has the mounting groove matching with throw rod cross section, throw rod penetrates in mounting groove and is flexibly connected; Mounting groove one side of actuating sleeve has tapped bore, and adjustable friction damper is threaded with actuating sleeve, forms friction and be flexibly connected between a face of adjustable friction damper and throw rod.
Described adjustable friction damper comprises: friction lining, elastic element, adjustable column, torsional stop, between friction lining and adjustable column, be provided with elastic element, and adjustable column and actuating sleeve are threaded, and friction lining and throw rod side plane are close to.
Described adjustable column exposes termination and is processed as multi-edge column-shaped, and torsional stop is connected with polygon prism groove and the hypotenuse supporting with adjustable column multi-edge column-shaped, and adjustable column is connected by polygon prism groove and the hypotenuse of multi-edge column-shaped and torsional stop.
Described actuating sleeve is provided with the interface with drive element, the adjusting position biasing of interface and adjustable friction damper; Adjustable friction damper adopts the biasing of homonymy left and right, or adopts the biasing of homonymy front and back, or adopts heteropleural biasing, or adopts deflection angle to setover.
Feature of the present utility model is: owing to being provided with adjustable friction damper 4 on actuating sleeve 6, make the friction force between actuating sleeve 6 and throw rod 5 adjustable, thereby reach the object that regulates actuating sleeve 6 dampings.Reduce switch machine bounce-back and cut off the probability failure that represents even release.Can solve the problem that damping diminishes after long-term use, improve Availability, Reliability And Maintain-ability.
Below in conjunction with executing routine accompanying drawing, the utility model is described further:
