A kind of cantilevered overpass bearing replacement device, including locomotive, manipulator, wherein the front upper fitting machine of locomotive
Tool hand, locomotive rear portion are arranged wagon box for holding bearing, the vertical arm of setting before the locomotive, and vertical arm is to side
Extend and extends to the bridge back side or less；The lower end of vertical arm is installed by lateral rotation arm in a rotatable manner；The transverse direction turns
Installation set is arranged in swing arm rear portion, and is mounted on lateral rotation arm lower end by installation set；It installs the front end of the lateral rotation arm
Counterweight is installed in branch attic base, rear end；In the front setting annular fluted disc of installation set, and driving device is set on vertical arm,
The engagement wheel engaged with annular fluted disc is installed in driving device；The branch attic base includes carrier, is arranged at the rear portion of carrier
Push plate, push plate are controlled by push rod, and push rod is mounted on and is fixed in the support base at carrier rear portion.
On above-mentioned machine in scheme, vertical arm is arranged in the front of locomotive so that locomotive laterally turns when on latter bridge
Branch attic base can be turned to the support position below previous bridge by swing arm through rotation, to replace the bearing of previous bridge.It can
The lateral rotation arm of rotation can avoid the blocking of bridge pier when the device passes through bridge pier again so that the device can carry out continuously
Property long-distance operation, save the bridge maintaining time.
Preferably, anticollision layer is arranged in the front end face edge of the carrier.Lateral rotation arm is rotated, branch attic base is made
It to be close to bridge pier wall surface, then could carries out the replacement of bearing, during this, branch attic base can be hit with bridge pier wall surface, if
Anticollision layer is set to be conducive to protect carrier.
Preferably, the vertically arranged spacer bar in the carrier front.Manipulator by bearing place with carrier on,
Bearing moves under the action of push plate, and spacer bar is arranged on carrier can reduce the frictional force suffered by bearing, meanwhile, isolation
Gap between bar can be carried out with bearing card and, play the role of positioning bearing.
