Description
Technical field:
The present invention relates to the cone type piercer technical field, is a kind of push rod drag chain jigger running gear specifically, and having solved ejector rob trolley provided existing drag chain can't be efficiently, the technical problem of reliability service.
Background technology:
Cone type piercer is the capital equipment that hot rolled seamless steel tube is produced, and the metal deformation district constitutes by top and bottom rolls, left and right sides guide plate (or godet) and top are common.The top is installed in the front end of push rod, and push rod is installed on the ejector rob trolley provided axletree.Ejector rob trolley provided outlet one side that is positioned at punch can move back and forth front and back down in the driving of a cover hoisting system, so that with push rod and the top position of sending into and deactivate.Ejector rob trolley provided needed energy medium comprises through drag chain, being connected to the pipeline and the control cable of hydraulic oil, lubricating oil, cooling water on the ejector rob trolley provided car body from the stiff end of drag chain.Before rolling, ejector rob trolley provided advancing, top and push rod are admitted to the operating position; When rolling end, ejector rob trolley providedly to return fast, hollow billet is left with push rod in the top, and rolling next time in the initial position wait.Punch is every once rolling, ejector rob trolley providedly all will move back and forth once.Ejector rob trolley provided movement travel long (27 meters of ranges, impulse stroke can reach 22 meters), time are short, therefore correspondingly require drag chain long, and also (length reaches 14.5 meters, speed 2 meter per seconds, acceleration 4 meter per seconds than higher for the speed of drag chain and acceleration
2).When the upper strata drag chain droops when the lower floor drag chain contacts, both phase mutual friction, chain link receives change impacts, is easy to fatigue fracture.If drag chain ruptures at the volley, also possibly cause medium pipeline and control cable breakage, even cause steel-fastening behind the punch, increase maintenance cost and accident cost greatly.Therefore, quality, reliability of operation and the regular maintenance to ejector rob trolley provided drag chain itself requires high.
Summary of the invention:
The objective of the invention is to overcome the deficiency of prior art, a kind of push rod drag chain jigger running gear is provided, mainly solve problems such as not high, the easy damage of existing drag chain functional reliability, influence production and increase maintenance cost.
In order to reach this purpose, the present invention is achieved in that a kind of push rod drag chain jigger running gear, it comprise ejector rob trolley provided drag chain and ejector rob trolley provided on medium pipeline; Medium pipeline and ejector rob trolley provided drag chain link together, and ejector rob trolley provided drag chain stiff end is fixed on the equipment supporter, and ejector rob trolley provided drag chain movable end is fixed on the ejector rob trolley provided car body; Its special character is that the both sides of ejector rob trolley provided rail brackets respectively establish a cover jigger guide rail, on every cover jigger guide rail, establishes a cover drag chain jigger, and the drag chain jigger moves on the jigger guide rail; The drag chain jigger is a strip, and there are two row's running rollers both sides, and there is row's carrying roller the inboard; Respectively there is wirerope wheel at drag chain jigger two ends; Wirerope is walked around two wirerope wheels, and the wirerope two ends are fixed on the wirerope tensioning apparatus, and the wirerope tensioning apparatus is installed on the ejector rob trolley provided rail brackets; Wirerope carries out tensioning through the wirerope tensioning apparatus, wirerope middle part through the wirerope fixture be fixed on ejector rob trolley provided on.
Further, said drag chain jigger realizes that through wirerope and the wirerope wheel that is located at drag chain jigger two ends Half Speed drags.
Compared with present technology a kind of push rod drag chain jigger running gear of the present invention has outstanding substantive distinguishing features and marked improvement: 1, adopt the drag chain jigger; Ejector rob trolley provided drag chain in carrying roller holder by on the drag chain jigger; Be rolling friction between ejector rob trolley provided drag chain and the carrying roller; Impaired light, reliable, the long service life of ejector rob trolley provided drag chain, thus maintenance cost can be reduced, the direct motion of support equipment safety; 2, the drag chain jigger is dragged by ejector rob trolley provided through wirerope and wirerope wheel, does not need supporting hoisting mechanism, and is simple in structure, reliable and practical.

The specific embodiment:
In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and specify the present invention.
Embodiment 1, referring to Fig. 1,2,3,4,5,6,7,8,9,10,11,12, by prior art ejector rob trolley provided drag chain 4 and medium pipeline installed; The two links together, and ejector rob trolley provided 1 moves back and forth before and after on ejector rob trolley provided guide rail under the driving of a cover hoisting system, and the stiff end of ejector rob trolley provided drag chain 4 is fixed on the equipment supporter; The movable end of drag chain 4 is fixed on ejector rob trolley provided 1 the car body, in the both sides of the rail brackets of ejector rob trolley provided 1 operation one cover drag chain jigger guide rail 2 is installed respectively, and a cover drag chain jigger 3 is installed on every cover jigger guide rail 2; Drag chain jigger 3 is a strip, and there are two row's running rollers both sides, and there is row's carrying roller the inboard; Drag chain jigger 3 moves on jigger guide rail 2; Respectively there is wirerope wheel 8 at drag chain jigger 3 two ends, and wirerope is walked around two wirerope wheels 8, and the two ends of wirerope 6 are fixed on the wirerope tensioning apparatus 5; Wirerope tensioning apparatus 5 is installed on ejector rob trolley provided 1 rail brackets; Wirerope 6 carries out tensioning through wirerope tensioning apparatus 5, and wirerope 6 middle parts are fixed on ejector rob trolley provided 1 through wirerope fixture 7, and drag chain jigger 3 realizes that through wirerope 6 and the wirerope wheel 8 that is located at drag chain jigger 3 two ends Half Speed drags.
A kind of push rod drag chain jigger running gear of the present invention; When ejector rob trolley provided motion; Ejector rob trolley provided dragging on the ejector rob trolley provided drag chain to the drag chain jigger, simultaneously ejector rob trolley provided the wheel with wirerope through wirerope drags the drag chain jigger, thereby makes the drag chain jigger with ejector rob trolley provided motion.When ejector rob trolley provided advancing, the wirerope of drag chain jigger rear end wheel is equivalent to a movable pulley, and guide rail travels forward the drag chain jigger in the pulling lower edge of wirerope; When ejector rob trolley provided retreating, the wirerope of drag chain jigger front end wheel is equivalent to another movable pulley, and guide rail moves the drag chain jigger backward in the pulling lower edge of wirerope; Because the reason of movable pulley, the movement velocity of drag chain jigger have only ejector rob trolley provided half the.So, when ejector rob trolley provided reciprocating motion, the drag chain jigger also and then moves back and forth together in the same way.Through the fixed position of adjustment wirerope on ejector rob trolley provided, drag chain jigger and ejector rob trolley provided is arrived simultaneously before extreme position and back extreme position.
