Description
Technical field
The present invention relates to contact net for power supplying detection field more particularly to a kind of contact line compensation device location information acquisition dresses
It sets.
Background technology
Contact line compensation device is automatic adjustment contact line and the compensation mechanism of load rope tensility and its general name of brake apparatus.
When the temperature is changed, clue is acted upon by temperature changes to expand with heat and contract with cold and elongate or shorten.Due in anchor section two
The end line rope place of casting anchor is mounted with compensator, under the action of its falling mound string gravity, is capable of the tension of adjust automatically clue and holding
Clue sag meets technology requirement, to make the stability of contact suspension be improved with elasticity, improves contact net operation
Quality.
Compensator is made of compensating sheave, compensation rope, bar with ball and eye, plummet rod, falling mound block and union piece.Compensating sheave point
For fixed pulley and movable pulley（It constructs identical）, fixed pulley change Impact direction, movable pulley can also be laborsaving in addition to changing Impact direction
The shift position and.Pulley is typically equipped with bearing.
It repays device and is serially connected in clue both ends and pillar bearing in anchor section, there is different benefits according to the difference of contact suspension type
Repay device structure.
Compensator makes the tension of clue keep balance by the gravity of falling mound string.When the temperature is changed, the flexible of clue makes pendant
Stone roller string rises and drop, and when the lifting of falling mound string is beyond allowable range, such as declining excessively makes falling mound string bottom surface contact ground or rising
Excessively plummet rod earrings hole is made to be stuck in fixed pulley slot, can all compensator be made to lose compensating action.Therefore with a, b of compensator
Value limits the range of falling mound string.
Contact net anchor section will appear offset under the effect of following factors：1）The tension imbalance of mid point anchor fixed point both sides
Lead to anchor field offset；2）Roadbed inclination leads to contact suspension weight tilt distribution in anchor section；3）The impact of wind-force or pantograph.
Contact net anchor field offset will produce following harm：The elastic property for destroying contact suspension, is unfavorable for current collection at high speed；
Easily cause the de- bow of pantograph or drill bow accident leads to the stagger of anchor point because anchor field offset can cause bracket to deviate（" it "
Word value）Change；The serious offset of bracket can cause the distance between carrier cable and ground connection object not enough to cause to discharge, and cause to feed
The serious contact net accidents such as breaker actuation and load the bitter end broken string of side.
Mid point anchor, general arrangement principle are to keep the tension of mid point anchor fixed point both sides clue equal as possible, and to the greatest extent may be used
It can be in the middle part of anchor section.Under special circumstances, when anchor segment length is shorter, mid point anchor can not be set, it is another by the hard anchor in anchor section one end
End line rope installs compensator, and hard anchor at this time is equivalent to mid point anchor.
