In Rear frame.
Preferably, it is located at the top of tire when counterweight is placed on front frame；It is located at when counterweight is placed in Rear frame
The top of steel wheel.
Preferably, described counterweight adopts the counterweight steel plate of arc.
Preferably, described counterweight includes the two parts being symmetrically disposed at front frame both sides or Rear frame both sides, every part
Counterweight is correspondingly arranged on a set of counterweight adjusting mechanism.
Preferably, front frame and Rear frame are hinged by swivel pin.
Compared with prior art, this utility model has a following beneficial technique effect:
This utility model is adjusted to the counterweight of setting on road roller by mechanical structure, the matter of distribution road roller
Amount, improves compaction quality and transition efficiency；In pavement compaction, the cooperation of the linkage being formed using major-minor arm hydraulic cylinder will
Counterweight moves forward, and increases steel wheel weight and greatly improves consolidation effect；During transition, the linkage that formed using major-minor arm hydraulic cylinder
Cooperation is rearmounted by counterweight, and increasing Rear frame weight increases rear car adhesive force and improve driving force.
Further, the counterweight being arranged by arc, that can not only improve that it is connected on front/rear frame is convenient
Property, and the impact to this body structure of car body for the counterweight can be reduced to greatest extent, and do not increase extra volume, counterweight is symmetrical
The top being arranged on tire, can preferably realize the weight of tire or steel wheel is loaded, improve it and corresponding drive or press
Actual effect fruit.
