Abstract
Disclosed is an impact-resistant anti-drop carrier roller for vertical rolls. The impact-resistant anti-drop carrier roller is arranged between two vertical rolls and comprises a carrier roller frame case body, a carrier roller group and two support crossbeams. Two sides of the carrier roller frame case body are connected with housing windows of the vertical rolls. The carrier roller group is arranged on the carrier roller frame case body and is limited by an upper gland bush. The two support crossbeams are respectively arranged at two sides of the carrier roller frame case body. The upper end of each support crossbeam is a bevel, one side of the support crossbeam is connected with the carrier roller frame case body, and the other side of the support crossbeam is arranged on the housing windows of the vertical rolls at two sides. By arranging the support crossbeams, impact to the carrier roller is totally born by the support crossbeams, and a bracket at the lower part only bears the force from a transverse positioning pin8. The unique structure of the support crossbeams makes the force to the support crossbeams totally split and transferred to the carrier roller frame case body and the housing windows at two sides, so the support crossbeams can not overturn under force. Therefore, impact resistance and vibration resistance of the carrier roller are improved by a large margin, thus meeting the requirements of reversible mills for thick slabs.
Description
Technical field
The utility model relates to the milling train field, particularly a kind of shock resistance slip-off preventing edger roll carrying roller.
Background technology
Carrying roller is mounted in the centre of two edger rolls in the middle of the edger roll, it is passive commentaries on classics that carrying roller itself does not have transmission, main effect is to play supporting steel plate during by vertical miller when steel plate, make steel plate can pass through vertical miller smoothly, carrying roller fixedly be to hold carrying roller by two bearings in carrying roller bottom, and bearing is just fixed by the bolt of 4 M48.It is the inlet of vertical miller at finishing mill that general vertical miller is forward type, and carrying roller just bears the power that steel plate is carried, and the edger roll idler structure of design can satisfy the requirement of technology fully at present.
But existing slab vertical miller is the rear-mounted outlet that is vertical miller at finishing mill, and finishing mill is a reversable mill.The edger roll carrying roller of existing structure need improve and further improve with regard to exposing some problems like this, and its outstanding shortcoming is: carrying roller cooling water deficiency, carrying roller insufficient lubrication, the support connecting bolt insufficient strength of carrying roller vertical direction location etc.Its consequence is exactly the fracture of support connecting bolt, and carrying roller is fallen into trench, and steel plate also will be scurried into trench thereupon.
The edger roll carrying roller is worked under huge impact power for a long time, frequently breaks down unavoidably.
Slab edger roll carrying roller fault is continuous, the fault of carrying roller mainly conclude following some:
Carrying roller located lateral pin comes off, and carrying roller is laterally moved, the possibility that causes the carrying roller secundly to cause monolateral gap to have greatly causing steel plate to scurry into the oil cellar.
Carrying roller cooling water deficiency causes carrying roller to be heated and rises extremely, causes the steel plate lower surface to scratch.
Invar plate discount directly hits on carrying roller, also directly pounds on carrying roller because of short steel billet, causes the fracture of carrying roller lower bracket set bolt to make carrying roller sink; In a single day carrying roller middle part backstop come off and will cause the carrying roller trench that drops, and at this moment the steel plate words of coming will be scurried into trench.
Summary of the invention
The purpose of this utility model is to design a kind of shock resistance slip-off preventing edger roll carrying roller, and it is strong to have an anti-impact force, is not subjected to the restriction of forward type and rear-mounted edger roll, can satisfy the requirement of slab reversable mill.
For achieving the above object, the technical solution of the utility model is,
A kind of shock resistance slip-off preventing edger roll carrying roller is arranged between two edger rolls; It comprises, carrying roller framework casing, and its both sides are connected with the edger roll memorial archway; The carrying roller group is arranged on the carrying roller framework casing, and spacing by upper press cover; It also comprises two supporting traverses, is arranged at carrying roller framework casing both sides respectively, and this supporting traverse top is an inclined-plane; This supporting traverse one side is connected with carrying roller framework casing, and opposite side is sat and is located on the edger roll memorial archway of both sides.
Further, described supporting traverse bottom radially has the through hole that wears for bolt; Offer a groove with the side that carrying roller framework casing leans; The both sides of corresponding two supporting traverses of described carrying roller framework casing are offered first fixed groove that is embedded for supporting traverse one end respectively, this first fixed groove bottom has and the corresponding connecting through hole of supporting traverse lower through-hole, by bolt supporting traverse is connected with carrying roller framework casing; One projection is formed at the top of carrying roller framework casing first fixed groove, and this projection is embedded at described supporting traverse lateral grooves; Described supporting traverse one side is embedded at carrying roller framework casing first fixed groove, and opposite side is sat and is located on the edger roll memorial archway of both sides.
Again, carrying roller framework casing described in the utility model both sides also offer second fixed groove, and edger roll memorial archway side that should carrying roller framework casing both sides is provided with projection, and this edger roll memorial archway projection is embedded at this second fixed groove.
In addition, carrying roller framework casing two bottom sides described in the utility model also is provided with the support of vertical direction location, and this support is connected with both sides edger roll memorial archway by connecting bolt.
Described support is connected with carrying roller framework casing by the located lateral pin, and the nut that gets loose of setting up defences.
Vertical direction at the edger roll carrying roller need be born huge impact load, intrinsic support connecting bolt can't bear so frequent shock loading at all, the utility model design increases by a supporting traverse at the middle part of edger roll body, drop on the edger roll memorial archway, original support connecting bolt is not stressed.Improved resistance to shock loads greatly.
The beneficial effects of the utility model
The utility model drops on original this body weight of carrying roller on the edger roll memorial archway, and impact resistance and anti-vibration ability significantly promote.The fault of edger roll carrying roller is thoroughly eliminated, guaranteed the quality of steel plate lower surface, thereby make the replacement cycle of carrying roller be extended for 3 months.
