Device；Parent application day: on November 21st, 2014.
Technical field
The invention belongs to railway security anti-slip parking facility field, particularly relate to the parking side of the anti roll device of a kind of cargo train
Method.
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
Anti-theft safety skate, the curved baffle on the toe-cap including sole, being arranged on sole, the footwear limit of sole both sides and toe-cap,
Described curved baffle is provided with the pressure tentaculum of a little higher than curved baffle, and pressure tentaculum is supported by the return spring being fixedly installed on sole；Institute
State the sole in toe-cap inner chamber and be provided with positioning seat, positioning seat is fixed with transverse axis and rotating shaft, described rotating shaft two respectively with arm
Bar is flexibly connected, and armed lever is connected with the pole through rotating shaft by auricle, arranges between described pole lower end and pressure tentaculum lower end
Have one to stick up bar, described in stick up bar through transverse axis, described transverse axis forms tapered end through toe-cap both sides.When this utility model uses, only
Skate need to be locked on rail with private key, be not required to use steel chain and lockset hook, will not be stolen, when wheel of vehicle presses to wheel stopper
During plate, wheel will open briquetting pressure, promote and open lever, lift armed lever, brake and be opened by footwear lock, and vehicle just can be slided backward
Move, even if skate is slid onto at rail joint, also do not result in wagon running away, the accident that slides down of derailing, also without compromising on locking machine
Structure.Although this utility model solves the problem that tradition skate is antitheft, but the return spring of pressure tentaculum is elastomeric element, to shipping
The heavy weight braking of train is it is possible that damage return spring and cause overturn accident；Use frequently and return spring also can be made elastic
It is gradually lowered, makes this utility model the longest for service life.
