As shown in Figure 4, heavy duty (large-scale workpiece) is placed on the step rate, and this moment, second group of jacking cylinder was take interior slide rail as fulcrum jack-up step rate and heavy duty; Subsequently, second group of piston rod of passing cylinder bounce back take interior slide rail as counter-force point, and the pulling step rate moves forward and the front end of interior slide rail extremely, i.e. its piston rod bounce back complete (first step A).Meanwhile, first group of passing cylinder passed external slide rail forward until first group of piston rod of passing cylinder stretches out fully, and first group of jacking cylinder piston rod stretches out; After the cylinder body of second group of passing cylinder is covered a stroke (being that its piston rod retraction is complete rear), second group of jacking cylinder puts down step rate and when beginning piston rod bounced back, first group of piston rod of passing cylinder stretches out fully, and first group of jacking cylinder piston rod be the contact external slide rail, and this moment, step rate and load just supported (first step B) by first group of jacking cylinder.First group of jacking cylinder is take external slide rail as fulcrum jack-up step rate and heavy duty; Subsequently, first group of piston rod of passing cylinder bounces back take external slide rail as counter-force point, and the pulling step rate moves forward until first group of piston rod retraction complete (second step A) of passing cylinder.Meanwhile, second group of passing cylinder passed interior slide rail forward until second group of piston rod of passing cylinder stretches out fully, and the piston rod of second group of jacking cylinder stretches out again; After the cylinder body of first group of passing cylinder is covered a stroke (being that its piston rod retraction is complete rear), first group of jacking cylinder puts down step rate and when beginning piston rod bounced back, second group of piston rod of passing cylinder stretches out fully, and the piston rod of second group of jacking cylinder is the interior slide rail of contact, this moment, step rate and load were just supported by second group of jacking cylinder, be returned to incipient state, prepare to be transitioned into slippage on the interior slide rail (second step B).Such two groups of jacking cylinders support step rate and slide in turn on inside and outside two slide rails, and per two steps, alternately once step rate can forward slippage of constant speed on inside and outside two slide rails, avoided the step wise slippage in the middle of pause.
The passing cylinder spurs step rate take slide rail as counter-force point principle is; Jacking cylinder jack-up load, thereby slide rail also carry load weight and since the effect of antifriction crawler shoe (present embodiment adopts crawler shoe to reduce friction, positive pressure on the pair of can also other conventional proper form reducing friction or friction coefficient reach the effect that reduces friction), friction force between jacking cylinder and slide rail is less than the friction force between slide rail and (cement) ground at this moment, so can slide rail be the counter-force point when passing the cylinder retraction, drive step rate forward slippage on slide rail.
In traveling process, if conveying arrangement of the present invention need to be adjusted direct of travel, then adjust by the cooperation of four groups of correction cylinder components, two passing displacement pickups and electric-control system.Can draw the data of passing the position by the data acquisition of passing displacement pickup, the skew instruction of sending according to passing position data and electric-control system produces four road offset displacements (i.e. four road offset displacements of four groups of correction cylinder components), makes the working direction of stepping Beam according to angle of control command skew.
Correction cylinder component and pass displacement pickup to adjust the Principle of Process of direct of travel as follows: first passes displacement pickup to passing displacement data and gather and feeding back to electric-control system, electric-control system allows the correction cylinder of first group and second group provide a side thrust to pass external slide rail accordingly, the skew that makes external slide rail can produce certain angle is stretched out, corresponding displacement pickup carries out data acquisition to offset displacement, then feeds back to electric-control system; Electric-control system reaches the passing displacement data accordingly allows the correction cylinder provide a side thrust to pass step rate, but makes step rate deflection slippage, and corresponding displacement pickup again carries out data acquisition and feeds back to electric-control system offset displacement subsequently.Second passes displacement pickup to passing displacement data and gather and feeding back to electric-control system, electric-control system reaches above-mentioned related data accordingly, allow the correction cylinder of the 3rd group and the 4th group provide a side thrust pass in slide rail, the skew that makes interior slide rail can cooperate the skew of step rate and external slide rail to produce certain angle is stretched out, corresponding displacement pickup carries out data acquisition to this offset displacement, then feed back to electric-control system, electric-control system sends next step instruction accordingly, and cycle control is until finish the adjustment of direct of travel.
Four groups of correction cylinder components are as follows to the detailed process of the adjustment of the direct of travel of conveying arrangement: when entering adjustment direction process, the first step, first group and second group collaborative adjusting of the cylinder component of rectifying a deviation on the step rate ejects external slide rail deflection, for stepping Beam deflection slippage is prepared; Second step, step rate deflection slippage under the reverse adjusting of first group and second group correction cylinder component; The 3rd step, the collaborative angular deflection of stretching out of regulating to make interior slide rail adapt to external slide rail and step rate of the 3rd group and the 4th group cylinder component of rectifying a deviation on the external slide rail is stretched out, so repeat to pass forward (can stop if having adjusted to required direction), just can realize the adjustment of the direct of travel of step rate, thereby realize the adjustment of conveying arrangement direct of travel.
The present invention is not limited to above-mentioned embodiment, if various changes of the present invention or modification are not broken away from the spirit and scope of the present invention, if these are changed and modification belongs within claim of the present invention and the equivalent technologies scope, then the present invention also is intended to comprise these changes and change.
