Described adjusting device 32 is arranged on the described tunnel type frame 1, can drive described plug detent mechanism 312 holds tightly or unclamps described plug 2, described adjusting device 32 comprises unclamping and pushes mechanism 321 and and hold tightly and push mechanism 322, can also comprise a screw lift 323.
Described unclamping pushes mechanism 321 and described holding tightly pushes the both sides that mechanism 322 is separately positioned on described swing span 3124, pushing described swing span 3124 respectively round about, unclamps or holds described plug 2 tightly thereby drive described a plurality of plug carrying roller.Described unclamping pushes mechanism 321 and described holding tightly pushes mechanism 322 and can be hydraulic cylinder, the front end of described hydraulic cylinder has telescopic piston rod, and is positioned at piston rod and the described post 3126 that holds that the described hydraulic cylinder front end of tunnel type frame 1 the same side stretches out and aligns.
Described screw lift 323 comprises a screw mandrel that can stretch in the horizontal direction, and described screw mandrel is connected the described outer end that pushes mechanism 321 of unclamping, and pushes mechanism 321 translation in the horizontal direction to drive described 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 described plug 2 and hold tightly, the described piston rod that pushes mechanism's 321 front ends that unclamps on the left of at first control is positioned at stretches out the described post 3126 that holds that promotion is connected the left side of described swing span 3124, described swing span 3124 is swung to the right, thereby spur the deflection of described a plurality of plug carrying roller clockwise direction, make described plug detent mechanism 312 be in the situation of opening maximum; Then by the slip of described wheel 315 in described guide rail 14, make described plug bracing frame 31 along the tunnel 11 axially enter described tunnel 11, when support frame as described above body 311 arrives the output shaft top of described jacking hydraulic cylinder 15, the output shaft of described jacking hydraulic cylinder 15 upwards pushes support frame as described above body 311, described wheel 315 breaks away from described guide rail 14, described plug 2 inserts between each plug carrying roller smoothly, and make described V-arrangement locating piece 313 match with described V-shaped groove body 12, described flat shape locating piece 314 matches with described 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 described piston rod that pushes mechanism's 321 front ends that unclamps retreats, and control the described piston rod that pushes mechanism's 322 front ends of holding tightly that is positioned at the right side simultaneously and stretch out the described post 3126 that holds that promotion is connected the right side of described swing span 3124, described swing span 3124 is swung to the left, spur the deflection counterclockwise of described a plurality of plug carrying roller, thereby a plurality of plug carrying roller is held described plug 2 tightly.
When needs unclamp and withdraw from plug 2, only need the described piston rod that pushes mechanism's 322 front ends of holding tightly of control to retreat, and the described piston rod that pushes mechanism's 321 front ends that unclamps on the left of control is positioned at simultaneously stretches out the described post 3126 that holds that promotion is connected the left side of described swing span 3124, described swing span 3124 is swung to the right, thereby spur the deflection of described 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 described plug detent mechanism 312 of adjustment to some extent, can by the flexible drive of described screw mandrel described unclamp push mechanism 321 in the horizontal direction near or away from described swing span 3124, thereby the described stroke that unclamps the piston rod that pushes mechanism 321 can change to some extent, thereby the hunting range that promotes described swing span 3124 changes to some extent, can make the openings of sizes of plug carrying roller change.
When described plug bracing frame 31 needs repairing, only need after described plug 2 withdraws from, the output shaft of controlling described jacking hydraulic cylinder 15 bounces back downwards, so described plug bracing frame 31 is fallen thereupon, described wheel 315 falls into described guide rail 14 again, described plug bracing frame 31 can be keeped in repair along the described frame body 10 of axially pulling out of described tunnel 11.
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, 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 repeatedly connecting the possibility of throwing off leakage of oil, be conducive to improve the precision of plug bracing or strutting arrangement opening degree, improved production efficiency, and reliable in structure, simple, cost is low.Yet the above only is 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.
