Abstract
An extension shaft bracket of a rolling mill comprises a frame which is formed by an upper beam, a lower beam and a vertical column and an upper drive hydraulic cylinder, and is characterized in that: the upper drive hydraulic cylinder is hinged and suspended on the upper beam, a bracket assembly is arranged on the frame, is slidably assembled on the vertical column, and comprises an upper bracket body and a lower bracket body which are fixedly connected with each other, the piston rod of the upper drive hydraulic cylinder is hinged with the bracket assembly, when a roller is changed, under the action of the upper drive hydraulic cylinder, the upper and the lower bracket bodies slide up and down along with the bracket assembly along the vertical column, and can respectively support an upper universal extension shaft sleeve and a lower universal extension shaft sleeve. The extension shaft bracket of the rolling mill has a simple structure, the cost is reduced, also the space is saved, the interferential problem of a lower drive hydraulic cylinder and a hydraulic cylinder for changing the roller in the existing extension shaft bracket of the rolling mill is avoided, and the plane layout difficulty of a steel rolling technology is solved.
Description
Technical field
The utility model relates to a kind of carriage, relates in particular to a kind of extension shaft for rolling mill carriage.
Background technology
At mill, connecing shaft tray is a kind of equipment of extensive employing.During mill roll, connect shaft tray and hold the universal-joint spindle axle sleeve earlier, treat that old roll roller is after extracting rolling-mill housing out, new roll roller is the feeding rolling-mill housing, and the roll homalocephalus can successfully be connected with the universal-joint spindle axle sleeve.
Referring to Fig. 1; Existing extension shaft for rolling mill carriage comprise drive hydraulic cylinder 1, down drive hydraulic cylinder 5 and drive bracket 2 respectively, bottom bracket 4 slides up and down along column 3, so that let bracket 2, bottom bracket 4 hold universal-joint spindle axle sleeve 6 and following universal-joint spindle axle sleeve 7 respectively during roll change; In milling train when work,, also will suitably go up and down bracket 2, bottom bracket 4 are in order to avoid with last universal-joint spindle axle sleeve 6, universal-joint spindle axle sleeve 7 bumps down.
The extension shaft for rolling mill carriage only just uses when mill roll; Can not use the carriage drive hydraulic cylinder during milling train work, still, existing extension shaft for rolling mill carriage must dispose two proportioning valves and two displacement transducers come the accurately lifting travel of control hydraulic cylinder; Therefore, increased cost; Simultaneously; Roll under the span condition of limited the mill master; The old factory rehabilitation that particularly reuses is in the time of need arranging mill train, because existing extension shaft for rolling mill carrier structure is complicated under limited span; Bottom bracket drives hydraulic cylinder and can interfere with the hydraulic cylinder that roll change is used, and brings difficulty for the steel rolling process floor plan.
The utility model content
The purpose of the utility model is to provide a kind of simple in structure, extension shaft for rolling mill carriage that cost is low.
The purpose of the utility model is to realize like this; A kind of extension shaft for rolling mill carriage comprises the framework that is made up of entablature, sill and column and go up driving hydraulic cylinder, it is characterized in that: said going up drives that hydraulic cylinder is hinged to be suspended on the entablature; Said framework is provided with saddle assemblies and is slidedly assemblied on the said column; Said saddle assemblies comprises pop-up support body and bottom bracket body and connects firmly, and said to go up the piston rod and the said saddle assemblies that drive hydraulic cylinder hinged, during roll change; Under the effect of last driving hydraulic cylinder, pop-up support body and bottom bracket body slide up and down along said column with saddle assemblies can hold universal-joint spindle axle sleeve and following universal-joint spindle axle sleeve respectively.
Above-mentioned saddle assemblies also comprises middle guide cylinder and connects firmly with above-mentioned pop-up support body and bottom bracket body that said middle guide cylinder is slidedly assemblied on the said column.
Said frame is fixed on the mill housing through bracing frame.
The utlity model has following beneficial effect; The utility model removes driving hydraulic cylinder down; Be connected with saddle assemblies through last driving hydraulic cylinder, make pop-up support body and bottom bracket body on the saddle assemblies can hold universal-joint spindle axle sleeve and following universal-joint spindle axle sleeve simultaneously respectively, not only simple in structure; Reduced cost; And conserve space, the problem that the hydraulic cylinder of having avoided following driving hydraulic cylinder and roll change in the existing extension shaft for rolling mill carriage to use interferes has solved the difficulty of steel rolling process floor plan.

The specific embodiment
Embodiment; A kind of extension shaft for rolling mill carriage; Comprise the framework that constitutes by entablature 8, sill 10 and two root posts 3 and go up and drive hydraulic cylinder 1; Last driving hydraulic cylinder 1 hinged being suspended on the entablature 8, framework is provided with saddle assemblies 9, and saddle assemblies 9 comprises that pop-up support body 9a, bottom bracket body 9c and middle guide cylinder 9b and three connect firmly; The piston rod and the saddle assemblies 9 of last driving hydraulic cylinder 1 are hinged, and middle guide cylinder 9b is slidedly assemblied on the column 3, and framework is fixed on the mill housing 11 through bracing frame 12; During roll change, under the effect of last driving hydraulic cylinder, pop-up support body 9a and bottom bracket body 9c slide up and down along column 3 with middle guide cylinder 9b can hold universal-joint spindle axle sleeve 6 and following universal-joint spindle axle sleeve 7 respectively.
Claims (3)
