Said swing span 3124 rotatably is connected the top of the connecting portion of said a plurality of plug carrying rollers; Said swing span 3124 can be swung on the vertical plane of the axis of tunnel type frame 1, holds tightly or unclamps said plug along with the said a plurality of plug carrying rollers of the swing of said swing span cooperate.Shown in the specific embodiment among Fig. 2 is that said swing span 3124 is downward opening portal structures; Be rotatably connected to the top of the connecting portion 3121B of the said first plug carrying roller in the middle of the top of said portal structures, the two ends, bottom of said portal structures are rotatably connected to the top of connecting portion 3123B of connecting portion 3122B and said the 3rd plug carrying roller of the said second plug carrying roller respectively.The concrete shape of said swing span 3124 may change according to the needs of reality to some extent, enumerates no longer one by one at this.
Said two hold post 3126 all extends along horizontal direction, and is fixedly connected on the middle part of the portal structures both sides of said swing span 3124 respectively.
Said adjusting device 32 is arranged on the said tunnel type frame 1; Can drive said plug detent mechanism 312 holds tightly or unclamps said plug 2; Said adjusting device 32 comprises unclamping and pushes mechanism 321 and and hold tightly and push mechanism 322, can also comprise a screw lift 323.
Said unclamping pushes mechanism 321 and said holding tightly pushes the both sides that mechanism 322 is separately positioned on said swing span 3124, pushing said swing span 3124 respectively round about, unclamps or holds said plug 2 tightly thereby drive said a plurality of plug carrying roller.Said unclamping pushes mechanism 321 and said and holds tightly and push mechanism 322 and can be hydraulic cylinder; The front end of said hydraulic cylinder has telescopic piston rod, and is positioned at piston rod and the said post 3126 that holds that the said hydraulic cylinder front end of tunnel type frame 1 the same side stretches out and aligns.
Said screw lift 323 comprises the screw mandrel that can stretch in the horizontal direction, and said screw mandrel is connected the said outer end that pushes mechanism 321 of unclamping, and pushes mechanism 321 translation in the horizontal direction to drive said unclamping.
Tandem rolling tube machine of the present invention plug bracing or strutting arrangement 3 course of action on it in use is described below:
When needs stretch into said plug 2 and hold tightly; The said piston rod that pushes mechanism's 321 front ends that unclamps on the left of at first control is positioned at stretches out the said post 3126 that holds that promotion is connected the left side of said swing span 3124; Said swing span 3124 is swung to the right; Thereby spur the deflection of said a plurality of plug carrying roller clockwise direction, make said plug detent mechanism 312 be in the maximum situation of opening; Then through the slip of said wheel 315 in said guide rail 14; Make said plug bracing frame 31 along the tunnel 11 the said tunnel 11 of axial entering; When support frame as described above body 311 arrived the output shaft top of said jacking hydraulic cylinder 15, the output shaft of said jacking hydraulic cylinder 15 upwards pushed support frame as described above body 311, and said wheel 315 breaks away from said guide rail 14; Said plug 2 inserts between each plug carrying roller smoothly; And making said V-arrangement locating piece 313 match with said V-shaped groove body 12, said flat shape locating piece 314 matches with said locating platform 13, to realize the accurate location to plug bracing frame 31 centers; After treating that at last plug 2 insertions finish; Controlling the said piston rod that pushes mechanism's 321 front ends that unclamps retreats; And control the said piston rod that pushes mechanism's 322 front ends of holding tightly that is positioned at the right side simultaneously and stretch out the said post 3126 that holds that promotion is connected the right side of said swing span 3124; Said swing span 3124 is swung to the left, spur the deflection counterclockwise of said a plurality of plug carrying roller, thereby a plurality of plug carrying roller is held said plug 2 tightly.
When needs unclamp and withdraw from plug 2; Only need the said piston rod that pushes mechanism's 322 front ends of holding tightly of control to retreat; And control the said piston rod that pushes mechanism's 321 front ends that unclamps that is positioned at the left side simultaneously and stretch out the said post 3126 that holds that promotion is connected the left side of said swing span 3124, said swing span 3124 is swung to the right, thereby spurs the deflection of said a plurality of plug carrying roller clockwise direction; Each plug carrying roller can unclamp from plug 2, and plug 2 can withdraw from smoothly.
When the specification of plug 2 changes the openings of sizes of the plug carrying roller that needs the said plug detent mechanism 312 of adjustment to some extent; Can through the flexible drive of said screw mandrel said unclamp push mechanism 321 in the horizontal direction near or away from said swing span 3124; Thereby the said stroke that unclamps the piston rod that pushes mechanism 321 can change to some extent; Thereby the hunting range that promotes said swing span 3124 changes to some extent, can make the openings of sizes of plug carrying roller change.
When said plug bracing frame 31 needs repairing; Only need after said plug 2 withdraws from; The output shaft of controlling said jacking hydraulic cylinder 15 bounces back downwards; So said plug bracing frame 31 is fallen thereupon, said wheel 315 falls into said guide rail 14 once more, can axially the pull out said frame body 10 of said plug bracing frame 31 along said tunnel 11 be keeped in repair.
What the mainframe on the tandem rolling tube machine of the present invention adopted is O shape structure; The mainframe of its strength and stiffness C shape of the prior art relatively structure will inevitably improve greatly; And the plug bracing frame on the plug bracing or strutting arrangement on the tandem rolling tube machine is arranged to separate with adjusting device but the structure of working in coordination, and need not in the plug bracing frame, to reserve the space of installation adjusting device, so improved the strength and stiffness of plug bracing frame; And simplified pipe arrangement and reduced pipeline because of repeatedly connecting the possibility of throwing off leakage of oil; Help improving the precision of plug bracing or strutting arrangement opening degree, improved production efficiency, and reliable in structure, simple, cost is low.Yet the above is merely preferable possible embodiments of the present invention, and unrestricted protection scope of the present invention, so the equivalent structure that all utilizations specification of the present invention and accompanying drawing content have been done changes, all is included in protection scope of the present invention.
