Description

A kind of roll-changing equipment of operation roll of mill

Technical field

The present invention relates to the milling equipment field, refer more particularly to a kind of roll-changing equipment of operation roll of mill.

Background technology

In medium and small cold-rolled strip enterprise, in the steel band Rolling Production process, often, working roller abrasion, damage or steel band roll specification because of changing, and need dismounting and change to make roller.At present, change working roll, major part still adopts balance sling, perhaps conventional method such as crane, crowbar cooperation.This roll-changing method, inefficiency, labour intensity is big, and roll changing time is long, influence of rolled production output.

Summary of the invention

The objective of the invention is to overcome above-mentioned weak point of the prior art and a kind of simple in structure, roll-changing equipment of shortening roll changing time, easy to operate, practical novel operation roll of mill is provided.

The present invention realizes in the following way:

A kind of roll-changing equipment of operation roll of mill includes traversing carriage 1, it is characterized in that: also include:

One elevating mechanism 3 is connected on the traversing carriage 1 by roller;

One horizontal support bar 7; Level is installed on the elevating mechanism 3;

One horizontal support bar hook 8 is installed on the rolling-mill housing 12;

One lifting hydraulic cylinder 4; Be installed on the traversing carriage 1, and be connected with elevating mechanism 3;

One telescopic hydraulic cylinder 5; Be installed on the elevating mechanism 3, and parallel with horizontal support bar 7;

One piston joint 6; Be installed on the flexible piston rod 51 of telescopic hydraulic cylinder 5;

One hydraulic control device 2; Be located on the traversing carriage 1;

Described lifting hydraulic cylinder 4 is connected with hydraulic control device 2 respectively with telescopic hydraulic cylinder 5.

Described traversing carriage 1 is provided with and moves wheel 11.

Piston rod attachment 6, one ends of the present invention are threaded with piston rod 51, and the other end is when the disassemble and assemble work roller, with the working roll end connection; Utilize piston rod 51 horizontal telescopic movings, pull out old working roll during dismounting, advance new working roll during assembling, carry out working roll and change operation.

Lifting hydraulic cylinder 4 of the present invention, main effect is to adjust elevating mechanism 3, and integral body such as superincumbent telescopic hydraulic cylinder 5 and horizontal support bar 7 are installed move up and down the location, horizontal support bar 7 is connected with horizontal support bar hook 8, like this, elevating mechanism 3, horizontal support bar 7 and rolling-mill housing 12 are just formed force structure, bear horizontal telescopic oil cylinder 5, the push-pull effort that when the disassemble and assemble work roller, produces.
