Described two groups of jacking cylinders, two groups of passing cylinders, four groups of correction cylinder components and two passing displacement pickups are all connected with electric-control system.
Operational process of the present invention and relative theory as described below:
As shown in Figure 4, heavy duty (large-scale workpiece) is placed on step rate, and now within second group of jacking cylinder, slide rail is fulcrum jack-up step rate and heavy duty; Subsequently, second group is passed slide rail within the piston rod of cylinder is counter-force point retraction, pulls step rate to move forward and to the front end of interior slide rail, i.e. its piston rod retraction complete (first step A).Meanwhile, pass cylinder by external slide rail forward until first group of piston rod passing cylinder stretches out completely for first group, and first group of jacking cylinder piston rod stretches out; When (namely after its piston rod retraction) after the cylinder body of second group of passing cylinder covers a stroke, when second group of jacking cylinder puts down step rate and starts piston rod to bounce back, first group of piston rod passing cylinder stretches out completely, and first group of jacking cylinder piston rod contact external slide rail, now step rate and load just support (first step B) by first group of jacking cylinder.First group of jacking cylinder take external slide rail as fulcrum jack-up step rate and heavy duty; Subsequently, first group of piston rod passing cylinder take external slide rail as counter-force point retraction, pulls step rate to move forward until first group of piston rod passing cylinder bounces back complete (second step A).Meanwhile, pass cylinder by interior slide rail forward until second group of piston rod passing cylinder stretches out completely for second group, and the piston rod of second group of jacking cylinder stretches out again; When (namely after its piston rod retraction) after the cylinder body of first group of passing cylinder covers a stroke, when first group of jacking cylinder puts down step rate and starts piston rod to bounce back, second group of piston rod passing cylinder stretches out completely, and the piston rod of second group of jacking cylinder is slide rail in contact, now step rate and load are just supported by second group of jacking cylinder, be returned to incipient state, prepare to be transitioned into slippage on 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 alternately once, step rate can constant speed slippage forward on inside and outside two slide rails, avoids the intermediate hold of step wise slippage for every two steps.
Passing cylinder is that counter-force point pulls the principle of step rate to be with slide rail; Jacking cylinder jack-up load, thus slide rail also carry load weight and due to antifriction crawler shoe effect (the present embodiment adopt crawler shoe reduce friction, can also other conventional proper form reduce positive pressure on friction pair or friction coefficient reaches the effect reducing friction), friction force now between jacking cylinder and slide rail is less than the friction force between slide rail and (cement) ground, so can slide rail be counter-force point when passing cylinder retraction, drive step rate slippage forward on slide rail.
In traveling process, if conveying arrangement of the present invention needs to adjust direct of travel, then adjusted by the cooperation of four groups of corrections cylinder component, two passing displacement pickups and electric-control systems.The data of passing position can be drawn by the data acquisition of passing displacement pickup, the offset commands sent 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 offset an angle according to control command.
The Principle of Process of correction cylinder component and passing displacement pickup adjustment direct of travel is as follows: first passes displacement pickup gathers passing displacement data and feeds 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 making 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; Accordingly and pass displacement data and allow correction cylinder provide a side thrust to pass step rate, make step rate deflect slippage, corresponding displacement pickup carries out data acquisition to offset displacement and feeds back to electric-control system electric-control system again subsequently.Second passes displacement pickup gathers passing displacement data and feeds back to electric-control system, electric-control system accordingly and above-mentioned related data, allow the correction cylinder of the 3rd group and the 4th group provide a side thrust pass in slide rail, the skew making interior slide rail that the skew of step rate and external slide rail can be coordinated to produce certain angle is stretched out, corresponding displacement pickup carries out data acquisition to this offset displacement, then electric-control system is fed back to, electric-control system sends next step instruction accordingly, and cycle control is until complete the adjustment of direct of travel.
The detailed process of four groups of correction cylinder components to the adjustment of the direct of travel of conveying arrangement is as follows: when entering adjustment direction process, the first step, first group on step rate and second group cylinder component synergic adjustment of rectifying a deviation makes external slide rail deflection eject, and prepares for stepping Beam deflects slippage; Second step, step rate deflects slippage under the reverse adjustment of first group and second group correction cylinder component; 3rd step, the 3rd group on external slide rail and the 4th group cylinder component synergic adjustment of rectifying a deviation makes the angular deflection of stretching out of interior slide rail adaptation external slide rail and step rate stretch out, repetition forward like this (can stop if having adjusted to required direction), just can realize the adjustment of the direct of travel of step rate, thus achieve the adjustment of conveying arrangement direct of travel.
The present invention is not limited to above-mentioned embodiment, if do not depart from the spirit and scope of the present invention to various change of the present invention or modification, if these are changed and modification belongs within claim of the present invention and equivalent technologies scope, then the present invention is also intended to comprise these changes and variation.
