Description
Technical field
The invention belongs to railway security anti-slip parking facility field, particularly relate to the anti roll device of a kind of cargo train.
Background technology
Boundary member in railway line is mostly the principle utilizing two braking rail to clamp wheel braking at present, and they have spring mechanical
The versions such as formula, electromagnetic type, fluid pressure type and dead-weight, all there is following defect in these boundary memberes: brake force is all by braking
After rail and part wheel extruding, friction produces, and brake force is the biggest, brakes less reliable, and the brake force of passive adding pressure type is less,
Alleviating not thorough, when involving, resistance is big and noise big, and installs complexity and injure primary track.Existing boundary member installs one
As be stock rail waist punch, then by bolt, the bracing frame of boundary member is fixed on stock rail, the most also to adjust
Tie distance, thus have impact on the safety of railway, add the difficulty of maintenance.
Tradition skate also is largely used to prevent wagon running away, and it is may be used that skate is stuck between wheel and rail prevention vehicle motion
The method leaned on, but owing to skate is artificially to be freely placed on circuit, leakage is put and is leakage removed skate and happen occasionally, and nothing after placing
Method is persistently kept an eye on, and timing can only be taked to patrol and examine, and the stolen thing of skate often occurs, and once carelessness makes vehicle runaway occur, will
There is automobile crash and human casualty accident.
China Patent Publication No.: 2014146959U, publication date: 2010.5.5, invention and created name is a kind of for Train brake
