Abstract
The utility model discloses a hot rolling coiler winding drum, which comprises a main shaft, an extension shaft, a plurality of stud bolts and nuts, wherein the stud bolts and the nuts are used for connecting the main shaft and the extension shaft, and the outer ends of the stud bolts extending out of the extension shaft are outer square heads. In addition, a wafer with an inner square hole is sleeved on the outer square head of each stud bolt; an anti-loosening plate is arranged between each two adjacent stud bolts; two circular holes are arranged on the anti-loosening plate; and the wafers are sleeved into the circular holes and welded with the circular holes. As the anti-loosening plate is arranged between each two adjacent stud bolts to enable the stud bolts to be mutually restrained and not to rotate, the hot rolling coiler winding drum effectively prevents the stud bolts from loosening, and the stud bolts can be conveniently locked without particular devices and special tools and only by a common torque wrench. The hot rolling coiler winding drum is convenient, rapid, time-saving, labor-saving, economical and safe.
Description
Technical field
The utility model relates to a kind of hot rolling coiler reel.
Background technology
Hot rolling downcoiler reel is the core monomer equipment on the hot rolling master rolling line, and generally between 550 ℃～750 ℃, band steel toe portion is huge to the impact of reel, its operating mode very severe for its operating temperature.Hot rolling master rolling line coiler mandrel mainly can be divided into Wedge type and rod-plunger formula by structure at present.What the utility model patent related to is the combination of multi-point pushing locking nut, cutting ferrule and the clamp of a whole set of particular design, is mainly used in rod-plunger formula hot rolling downcoiler reel.
Rod-plunger formula hot rolling downcoiler reel mainly is made up of main shaft, mandrel, fanning strip and outrigger shaft.Its structure is that mandrel is contained in the centre of reel hollow spindle, and four fanning strips, 90 degree each other are contained in the outside of main shaft, and are connected with mandrel with bearing pin by connecting rod.Plunger is equipped with in spool spindle inside, and heat-resisting compression spring is housed in the plunger.For the needs that increase rigidity, the reel fore side has the auxiliary outer outrigger shaft that supports, and overlaps studs by eight between spool spindle and is connected with nut.
Rod-plunger formula reel structure novelty, simple structure, easy to maintenance, but in use its outrigger shaft connects double-screw bolt and only depends on that to smear thread locking glue locking.When low temperature batched high-strength line-pipe steel, the impact that reel is subjected to was big especially, and it is loosening double-screw bolt once repeatedly to occur, and the reel outrigger shaft is beated and surpassed the fault of design permissible value.Reel does not arrive design service life, and just machine maintenance is multiple down, greatly influences the continuous ordinary production of hot rolling line, all causes greater loss for hot rolling mill and reel production unit.
The utility model content
The purpose of this utility model is to provide a kind of hot rolling coiler reel that can effectively prevent bolt looseness.
This hot rolling coiler reel that the utility model provides, comprise main shaft, outrigger shaft, some stud and nuts that is used to connect described main shaft and outrigger shaft, described stud is outer square toes in the outer end of stretching out outrigger shaft, other has the disk of square hole in the band to be enclosed within on the outer square toes of described stud, between the two adjacent studs locking plate is arranged, two circular holes are arranged on this locking plate, be used to pack into described disk and welding with it.
In order to prevent the rotation of stud, described nut is provided with some little screws, described stud is carried out locking fastening by corresponding some Screws by described little screw.
The utility model hot rolling coiler reel, owing between two studs, be provided with locking plate, make between the stud and pin down mutually, can not rotate again, effectively prevented the loosening of stud, and do not need special device and specific purpose tool, only need common torque wrench just it can easily be locked.The utility model is convenient and swift, and is time saving and energy saving, economic security.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A profile of Fig. 1.
The specific embodiment
From Fig. 1 and Fig. 2 as can be seen, this hot rolling coiler reel of the present utility model, comprise main shaft 1, outrigger shaft 2, some studs 3 and nut 4, wherein stud 3 and nut 4 are used to connect main shaft 1 and outrigger shaft 2, a pad 6 is arranged between stud 3 and the nut 4, nut 4 is provided with some little screws, by little screw stud 3 is carried out locking fasteningly by corresponding some Screws 41, prevents that nut 4 and Screw 41 integral body from getting loose from main shaft 1.When the fastening stud 3 of need, at first nut 4 is twisted back cushion sheets 6 with manual mode, return nutting 4 then, the about 1～1.5mm in gap of control nut 4 and pad 6.Intersect with small wrench and to tighten whole Screws 41 in advance, repeatedly intersect one by one with manual torque wrench at last and tighten Screw 41, rely on all Screws 41 with pad 6 that outrigger shaft 2 contacts on axial jacking force that stud 3 is produced, lock outrigger shaft 2.
Stud can firmly be connected main shaft 1 with outrigger shaft 2, thereby guarantee the normal operation of equipment.
Claims (2)
1. hot rolling coiler reel, comprise main shaft (1), outrigger shaft (2), some stud (3) and nuts (4) that is used to connect described main shaft (1) and outrigger shaft (2), it is characterized in that described stud (3) is outer square toes in the outer end of stretching out outrigger shaft (2), other has the disk (31) of square hole in the band to be enclosed within on the outer square toes of described stud (3), the plate of loosening (5) is arranged between the two adjacent studs, this loosens two circular holes on the plate (5), be used to pack into described disk (31) and welding with it.
