Slewing arrangement of the present utility model and rolling is provided with between a body to drive and rolls a jacking system of body up-and-down movement, slewing arrangement can drive jacking system and roll a body and rotate, jacking system can drive and roll a body up-and-down movement, can easily workpiece be transmitted in the rotation that has between two stations of the vertical discrepancy in elevation, bring convenience to transportation work.
In addition, the slide block structure that arranges on the crank structure of jacking system be arranged on the chute that rolls on a body and form sliding pair, jacking system and rolling also arranges the promising guide piece that rolls the up-and-down movement guiding of a body between a body, guide piece can guarantee to roll a body and not produce planar movement and only move up and down, the motor-driven crank structure rotates, and crank drives slide block structure one side mobile driving in the chute that rolls a body on one side and rolls body up-and-down movement under the constraint of guiding mechanism.Of the present utility model simple in structure, motion is steady, and kinematic mechanism can steadily slow down before rolling a body to move to highs and lows, can not produce impact.In addition, crank structure is four, is separately positioned on the two ends of two wheel shafts, and motor drives four crank structures by synchronous drive mechanism and rotates and provide the power of up-and-down movement, power to be evenly distributed to have guaranteed to roll the reliable easy motion of a body for rolling a body.
The track adjusting wheel of the utility model guiding mechanism is rotated and is assemblied on jacking system, the side face of track adjusting wheel coordinates with the corresponding side surface that is fixedly installed on the square guidepost that rolls bed body bottom to be realized rolling a body with respect to the guiding of jacking system, make and roll a body and can only can not all around move with respect to the jacking system up-and-down movement, guidance mode is ingenious, it is friction of rolling between guidepost and track adjusting wheel, friction force is little, and motion flexibly.
Guide frame of the present utility model comprises a pair of guidepost that is arranged on same straight line, the relative side of two guideposts coordinates guiding with separately track adjusting wheel, all coordinate with corresponding separately track adjusting wheel with adjacent to side guidepost side, it is good that guidepost is set to two guide effect.
Crank structure of the present utility model is eccentric roller, and intensity, the rigidity of eccentric roller are larger, good reliability.
