Abstract

The utility model relates to a novel roll changer of the work roll, which is used in the medium and heavy plate production line of a large iron and steel corporation as equipment for changing the work roll of the mill. The roll changer is composed of a body, an orbit, a driving device and a roll changing trolley. The structure of the roll changer is that the body is composed of a first body and a second body which are arranged on the fixed orbit on the both sides at the front of the roll changer and driven by a first transverse cylinder and a second transverse cylinder; the roll changing trolley is installed on the opposite of the work roll. The orbit is composed of a moving orbit and a fixed orbit; the moving orbit is controlled by an orbit position controlling cylinder, which can be connected with the fixed orbit to be a whole or be a right angle to be taken back. The utility model has features of novel structure, shortening the change time, less land occupied, low weight and saving investment, so which belongs to a novel roll changer of the work roll with economy and practicality together.

Description

The new type working roll changing machine

Technical field

The utility model relates to a kind of new type working roll changing machine, is to be applied to a kind of equipment that operation roll of mill is changed in the iron and steel corporation Heavy Plate Production line.

Background technology

What the operation roll of mill changing machine of at present domestic hot rolled steel plate production unit was commonly used is that hydraulic cylinder promotes Traverse Displacement Unit, and another one hydraulic pressure push-and-pull cylinder is used for working roll outside milling train is pulled out to roll line.The structure floor space is big, and weight of equipment is big, and hydraulic cylinder travel is limited, working roll directly can not be moved between grinding roller.Need be suspended on the car that collapses by crane, and just can forward between grinding roller.Present steel plant all require working roll system directly to move between grinding roller as long as the place can be satisfied.So just needing the so long stroke structure of roll change buggy just can meet the demands.Need when changing backing roll the work roll shifting support body is hung away with overhead traveling crane, for backing roll is reserved enough spaces, like this process influence roll change cycle, operation is also complicated.At existing problem in the above-mentioned prior art, a kind of novel work roll changing machine of research and design, existing problem is very necessary in the prior art thereby overcome.

Summary of the invention

In view of existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of novel work roll changing machine of research and design, thereby existing floor space is big in the solution prior art, and weight of equipment is big. the roll change cycle is long, and operation is also than complicated problems.A kind of new type working roll changing machine described in the utility model is made up of car body, track, drive unit and roll change buggy.Its structure is that car body is made up of car body one and car body two, divides to be listed on the trapped orbit of both sides, working roll front, and is driven by the traversing cylinder one and the traversing cylinder two on apportion both sides respectively.Roll change buggy is installed in the opposite of working roll.Track is made up of movable rail and trapped orbit, and movable rail can be connected into one with trapped orbit by the control of rail position control cylinder, or the withdrawal that meets at right angles.

The utility model mainly is fixed roll change cross moving track to be changed to movable, and at ordinary times milling train when work, track is packed up, and could release when having only the working roll of replacing, forms complete roll change cross moving track with trapped orbit.Two parts about traversing support body also is divided into are held new, old working roll system respectively, respectively by two traversing Driven by Hydraulic Cylinder.When changing backing roll, traversing support body and movable rail move to both sides respectively, vacate the centre position, backing roll just from then on the space shift out milling train.Effect is:

1) reduces the roller roll change program step that changes jobs, shorten roll changing time.

2) help changing backing roll, reduce roll change time, take on-the-spot place less.

3) weight of equipment is light, reduces investment outlay.

Advantages such as the utlity model has novel structure, shorten roll changing time, take up an area of less, weight of equipment is light, reduce investment outlay, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.

Description of drawings

The utility model has two accompanying drawings, wherein

Accompanying drawing: 1, a kind of new type working roll changing machine structural representation

Accompanying drawing: 2, a kind of new type working roll changing machine track structure schematic diagram

Among the figure: 1, traversing cylinder 1, car body 1, roll change buggy 4, car body 25, traversing cylinder 26, rail position control cylinder 7 movable rail 8, trapped orbit

The specific embodiment

Specific embodiment of the utility model as shown in drawings, car body 1 and car body were listed on the trapped orbit 8 of both sides, working roll front in 24 minutes, and were driven by the traversing cylinder 1 on apportion both sides and traversing cylinder 25 respectively.Roll change buggy 3 is installed in the opposite of working roll.Movable rail 7 can be connected into one with trapped orbit 8 by 6 controls of rail position control cylinder, or the withdrawal that meets at right angles.

Car body 1 shown in the accompanying drawing 1 and car body 24 be respectively by 25 controls of traversing cylinder 1 and traversing cylinder, is positioned on the trapped orbit 8 of ready position of both sides, milling train center.Two car bodies can move to the center of milling train respectively.New roller and old roller lay respectively on two car bodies.Pulling out and push by roll change buggy 3 push-and-pulls of working roll realizes.State when the rail position control cylinder 6 control movable rail 7 shown in the accompanying drawing 2 are sentenced roll change state and milling train work respectively.

Claims

1. a new type working roll changing machine is made up of car body, track, drive unit and roll change buggy (3); It is characterized in that car body is made up of car body one (2) and car body two (4), divide to be listed on the trapped orbit (8) of both sides, working roll front, and respectively by the traversing cylinder one (1) and two (5) drivings of traversing cylinder on apportion both sides; Roll change buggy (3) is installed in the opposite of working roll; Track is made up of movable rail (7) and trapped orbit (8), and movable rail (7) is by rail position control cylinder (6) control, can and trapped orbit (8) be connected into one, or the withdrawal that meets at right angles.
