Abstract
一种轧机接轴托架，包括由上横梁、下横梁及立柱构成的框架和上驱动液压缸，其特征在于：所述上驱动液压缸铰接悬挂在上横梁上，所述框架上设有托架组合体并滑动装配在所述立柱上，所述托架组合体包括上托架体和下托架体且固联，所述上驱动液压缸的活塞杆与所述托架组合体铰接，换辊时，在上驱动液压缸的作用下，上托架体和下托架体随托架组合体沿所述立柱上下滑动可分别托住上万向接轴轴套和下万向接轴轴套。本实用新型不仅结构简单，降低了成本，而且节约空间，避免了现有轧机接轴托架中的下驱动液压缸与换辊用的液压缸发生干涉的问题，解决了轧钢工艺平面布置的困难。
A shaft connection bracket for a rolling mill, including a frame composed of an upper beam, a lower beam and a column, and an upper driving hydraulic cylinder, characterized in that: the upper driving hydraulic cylinder is hinged and suspended on the upper beam, and the frame is provided with a bracket The bracket assembly is slidingly assembled on the column, the bracket assembly includes an upper bracket body and a lower bracket body and is fixedly connected, and the piston rod of the upper driving hydraulic cylinder is hinged to the bracket assembly, When changing rolls, under the action of the upper drive hydraulic cylinder, the upper bracket body and the lower bracket body slide up and down along the column with the bracket assembly to hold the upper universal joint shaft sleeve and the lower universal joint shaft respectively bushing. The utility model not only has a simple structure, reduces the cost, but also saves space, avoids the problem of interference between the lower drive hydraulic cylinder in the existing rolling mill shaft bracket and the hydraulic cylinder for roll change, and solves the difficulty in the plane layout of the steel rolling process .
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.
